[0004] The 3GPP has been working on the standardization of LTE (E-UTRAN). In the absence of UL data, data-non-associated control signals (e.g., ACK/NACK, periodic CQI) are transmitted on the PUCCH. Furthermore, it has been decided that:

(a) ACK/NACK (only) signals are transmitted utilizing modulated CAZAC₁ sequences (coherent): BPSK is used for 1-bit ACK/NACK and QPSK for 2-bit ACK/NACK. Block-wise spreading with SF=3/SF=4 (pilot/data) is applied for the modulated CAZAC sequences.
1 The applied sequences may not be true CAZAC but computer searched Zero-Autocorrelation (ZAC) sequences. The same sequences are applied as reference signals with bandwidth allocation of one resource block.

(b) Periodic CQI (and combinations of CQI and ACK/NACK) is also transmitted utilizing modulated CAZAC sequences. Block-spreading is not used.

[0005] In the 3GPP TSG RAN WG1 meeting #47bis in Sorrento, it was agreed that a non-contention based SR mechanism for time synchronized users will be supported.

[0006] The basic principles for SR multiplexing were agreed to in the 3GPP TSG RAN WG1 meeting #50bis in Shanghai. Reference in this regard may further be made to R2-074333, 3GPP TSG-RAN WG2#59bis, Alcatel-Lucent, "Handling NAS messages during HO," October 8-12, 2007, Shanghai, China.

[0007] In the Shanghai meeting, the following was also decided:

(i) There are two sizes of the SR corresponding to two states. Either the UE requests to be scheduled or (in case of no transmission) the UE does not request to be scheduled.

(ii) On-off keying based on ACK/NACK design: The length 7 sequence is split into two orthogonal sequences of length 3 and length 4. FIG. 1 shows the length 7 sequence 40 with two constituent orthogonal sequences 42, 44 of lengths 3 and 4, respectively.

(iii) There will be compatibility with ACK/NACK transmissions from different UEs.

(iv) Different resources corresponding to a cyclic shift and an orthogonal cover code can be assigned for scheduling requests and ACK/NACK.

[0008] It is noted that the ACK/NACK signaled on the UL is related to DL-SCH (Physical Downlink Shared Channel, PDSCH). In the case where the UE has no data to transmit (i.e., on the UL), the ACK/NACK is signaled on the PUCCH. When the UE has UL data to transmit, the ACK/NACK is signaled on the PUSCH.

[0009] 3GPP document "Multiplexing of Scheduling Request and ACK/NACK and/or CQI", R1-073011, describes a method of combining scheduling request and acknowledgement and transmitting them on an ACK allocated resource.

DETAILED DESCRIPTION:

[0026] Consider a multiplexing case where data-non-associated control signals, such as ACK/NACK (e.g., DL ACK/NACK) and/or periodic CQI, exist simultaneously with an UL SR. Further assume that the UE is not transmitting UL data since separate SR/buffer status reporting principles will be used when the UE has scheduled UL data transmission on the PUSCH. As noted above, in the absence of UL data data-non-associated control signals are transmitted on the PUCCH.

[0027] To date, SR decisions made in 3GPP RAN1 only cover the case where a SR is transmitted standalone. However, it may occur that the SR is transmitted with additional data-non-associated control signals, such as ACK/NACK and/or periodic CQI (e.g., ACK/NACK + SR, periodic CQI + SR, periodic CQI + ACK/NACK + SR). Various complications may arise in such cases.

[0028] FIG. 2 illustrates an example of ACK/NACK and SR resource assignments for UL transmissions on the PUCCH. In FIG. 2, ACK/NACK and SR have been configured for different frequency-hopping radio resources. FIG. 3 shows an example of ACK/NACK resources configured for 18 parallel ACK/NACK channels. FIG. 4 shows an example of SR resources configured for 72 parallel SR channels.

[0029] Each UE has certain code resources allocated to two different channels: one UE may occupy, for example, the eighth (8th) ACK/NACK resource and the twenty-eighth (28th) SR resource, respectively (see FIGS. 3 and 4).

[0030] One problem with the considered signaling combinations is related to the single-carrier property of LTE UL - it is not possible to transmit signals via multiple frequency bands (see FIG. 2) such that the beneficial low PAR properties of single-carrier transmission are maintained. However, due to the lack of a common pilot in the UL direction, it would not be economical to transmit two low rate control signals (e.g., SR + ACK/NACK and/or CQI) via two separate clusters (or via four clusters if SR and ACK/NACK and/or CQI have been configured into non-overlapping frequency resources).

[0031] There are some prior art techniques being discussed in RAN1 to avoid the multicarrier/multi-cluster transmission in the presence of a SR:

(a) One technique is to prioritize a predetermined signaling type (e.g., ACK/NACK instead of SR or SR instead of CQI). This means that when two signaling types exist in a same subframe, only the signaling type with the higher priority is transmitted whereas the lower priority signaling is not transmitted at all. One problem with this approach is the increased SR (or CQI) delay. This delay may be significant, for example, in a VoIP application.

(b) Periodic CQI + SR: The idea would be to arrange the periodic CQI reporting and SR signaling in such a way that they do not appear in a same subframe. One problem with this approach is that the arrangement will introduce limitations for either SR or CQI signaling. This may also be difficult to arrange as the periodicity of SR and CQI may not be the same.

(c) ACK/NACK + SR: It is possible to avoid this situation by introducing certain scheduler limitations for UEs being allocated for the given SR resource (i.e., do not allocate DL data for a time resource which will cause an ACK/NACK transmission to occur for a TTI in which the UE has simultaneous SR transmission).

(d) It would also be possible to develop a special multiplexing scheme for different alternatives (e.g., different schemes for ACK/NACK + SR, periodic (CQI + SR, ACK/NACK + periodic CQI + SR). Problems with this approach are related to link performance (modulation method) and/or resource allocation (multicode method, sequence selection method). Reference with regard to this technique may be made to commonly-owned U.S. provisional patent application no. 60/936,033, "Multiplexing of Scheduling Request and ACK/NACK and/or CQI Transmitted on PUCCH" by Tiirola et al. filed on June 18, 2007 (attorney docket no. 863.0067.P1(US)). Further reference in this regard may be made to R2-074139, 3GPP TSG-RAN WG2#59bis, NEC, "X2 downlink forwarding delay," October 8-12, 2007, Shanghai, China.

[0032] Exemplary embodiments of the invention provide improved techniques for signaling a SR with an ACK/NACK and/or CQI. In some exemplary embodiments, different multiplexing procedures are provided for cases with positive SR than for cases with negative SR. In accordance with the 3GPP TSG-RAN WG1#50bis Shanghai decisions, when the SR is transmitted standalone, only positive SRs are signaled (i.e., there is no transmission for negative SR).

[0033] In one, non-limiting exemplary embodiment of the invention:

(i) For negative SR, the ACK/NACK and/or CQI are signaled using original ACK/NACK (ACK/NACK PUCCH) and/or CQI resources (CQI PUCCH).

(ii) For positive SR, the ACK/NACK signal is transmitted using the SR resources (SR PUCCH). Transmission of the ACK/NACK on the SR resource(s) can be performed in a similar way to when ACK/NACK is transmitted on the ACK/NACK resource (unmodulated sequence 1 and modulated sequence 2 or unmodulated sequence 1 and unmodulated sequence 2). In this case, the ACK/NACK resource (ACK/NACK PUCCH) is left unused.

(iii) For positive SR without a simultaneous ACK/NACK signal, the SR signal is transmitted using the original SR resource(s), SR PUCCH. The simultaneous CQI is dropped (i.e., not transmitted) and the CQI resource(s), (CQI PUCCH)is left unused.

[0034] In such a manner, simultaneous transmission of ACK/NACK and (positive) SR is supported whereas there is no provision for simultaneous transmission of (positive) SR and CQI.

[0035] It is briefly noted that, as utilized herein, "positive SR" signifies that the UE desires to transmit a SR (e.g., to a Node B). Similarly, "negative SR" indicates that the UE does not desire to transmit a SR (e.g., to a Node B). Any reference to "resource" should be construed as covering a single resource or multiple resources assigned for the specified signaling.

[0036] With a negative SR, it is possible to signal the ACK/NACK and/or CQI using the original resources allocated for ACK/NACK or CQI, respectively. The SR resource(s) is left (SR PUCCH) unused. Thus, the following hold: If there is a negative SR and an ACK/NACK, transmit the ACK/NACK using only the original ACK/NACK resource(s), ACK/NACK PUCCH. If there is a negative SR and a CQI (e.g., periodic CQI), transmit the CQI using only the original CQI resource(s), CQI PUCCH. If there is a negative SR and both ACK/NACK and a CQI, transmit the ACK/NACK and CQI using only the original ACK/NACK and CQI resources, CQI PUCCH respectively.

[0037] As noted above, with a positive SR, simultaneous transmission of ACK/NACK and SR is supported whereas there is no support for simultaneous transmission of CQI and SR. Simultaneous transmission of ACK/NACK and positive SR is performed using the SR resource(s), SR PUCCH. Thus, the following procedures are applied:

[0038] If there is a positive SR and an ACK/NACK, signal the ACK/NACK using the existing SR resource(s), SR PUCCH. The ACK/NACK resource(s), ACK/NACK PUCCH, are left unused. The ACK/NACK can be transmitted similarly to when it is transmitted on its own resource (e.g., unmodulated sequence 1, BPSK/QPSK-modulated sequence 2).

[0039] If there is a positive SR and a CQI (e.g., periodic CQI), the SR is prioritized over the CQI. That is, transmit the SR using only the original SR resource (e.g., on the PUCCH). The CQI resource, CQI PUCCH is left unused.

[0040] If there is a positive SR and both ACK/NACK and CQI, the ACK/NACK is signaled using only the original SR resource (e.g., on the PUCCH). The CQI resource, CQI PUCCH is left unused and the CQI is not transmitted. The ACK/NACK can be transmitted similarly to when it is transmitted on its own resource (e.g., unmodulated sequence 1, BPSK/QPSK-modulated sequence 2).

[0041] On the Node B side, the Node B is responsible for the UL/DL resource allocation (e.g., for CQI, DL data and ACK/NACK, SR). Therefore, the Node B can receive the ACK/NACK, CQI and SR from the various resources, taking into account the different UE operation in light of positive or negative SR.

[0042] In further exemplary embodiments, the Node B can modify the above-stated prioritizations, for example, using RRC signaling (e.g., cell-specific, UE-specific). In such a manner, and as a non-limiting example, the Node B could modify the prioritization such that CQI is prioritized over ACK/NACK.

[0043] FIG. 5 shows a flowchart illustrating one non-limiting example of a method for practicing the exemplary embodiments of this invention. In box 52, it is determined whether there is a positive SR ("YES") or a negative SR ("NO"). If there is a negative SR, the method proceeds to boxes 54 and 56. In box 54, if there is an ACK/NACK (w/o CQI), the ACK/NACK is transmitted using ACK/NACK resources and the SR resources are unused. In box 56, if there is a CQI (with or without ACK/NACK), the CQI (or CQI+ACK/NACK) is transmitted using CQI resources, CQI PUCCH, and the SR resources (and ACK/NACK PUCCH) are unused. If there is a positive SR ("YES" for box 52), the method proceeds to box 58. In box 58, it is determined whether ACK/NACK is present ("YES") or not ("NO"). If ACK/NACK is not present ("NO" for box 58), then in box 60 the SR is transmitted using the SR resources and the additional resource which may be data-non-associated (DNA) resources, such as ACK/NACK PUCCH and CQI PUCCH are unused. No CQI is transmitted, regardless of whether or not it is present. If ACK/NACK is present ("YES" for box 58), then in box 62 the ACK/NACK is transmitted using the SR resources and the DNA resources, such as ACK/NACK PUCCH and CQI PUCCH are unused. No CQI is transmitted, regardless of whether or not it is present.

[0044] Reference is made to FIG. 6 for illustrating a simplified block diagram of various electronic devices that are suitable for use in practicing the exemplary embodiments of this invention. In FIG. 6, a wireless network 12 is adapted for communication with a user equipment (UE) 14 via an access node (AN) 16. The UE 14 includes a data processor (DP) 18, a memory (MEM) 20 coupled to the DP 18, and a suitable RF transceiver (TRANS) 22 (having a transmitter (TX) and a receiver (RX)) coupled to the DP 18. The MEM 20 stores a program (PROG) 24. The TRANS 22 is for bidirectional wireless communications with the AN 16. Note that the TRANS 22 has at least one antenna to facilitate communication.

[0045] The AN 16 includes a data processor (DP) 26, a memory (MEM) 28 coupled to the DP 26, and a suitable RF transceiver (TRANS) 30 (having a transmitter (TX) and a receiver (RX)) coupled to the DP 26. The MEM 28 stores a program (PROG) 32. The TRANS 30 is for bidirectional wireless communications with the UE 14. Note that the TRANS 30 has at least one antenna to facilitate communication. The AN 16 is coupled via a data path 34 to one or more external networks or systems, such as the internet 36, for example.

[0046] At least one of the PROGs 24, 32 is assumed to include program instructions that, when executed by the associated DP, enable the electronic device to operate in accordance with the exemplary embodiments of this invention, as discussed herein.

[0047] In general, the various exemplary embodiments of the UE 14 can include, but are not limited to, user equipments, terminals, mobile phones, cellular phones, personal digital assistants (PDAs) having wireless communication capabilities, portable computers having wireless communication capabilities, image capture devices such as digital cameras having wireless communication capabilities, gaming devices having wireless communication capabilities, music storage and playback appliances having wireless communication capabilities, Internet appliances permitting wireless Internet access and browsing, as well as portable units or terminals that incorporate combinations of such functions.

[0048] The embodiments of this invention may be implemented by computer software executable by one or more of the DPs 18, 26 of the UE 14 and the AN 16, or by hardware, or by a combination of software and hardware.

[0049] The MEMs 20, 28 may be of any type suitable to the local technical environment and may be implemented using any suitable data storage technology, such as semiconductor-based memory devices, magnetic memory devices and systems, optical memory devices and systems, fixed memory and removable memory, as non-limiting examples. The DPs 18, 26 may be of any type suitable to the local technical environment, and may include one or more of general purpose computers, special purpose computers, microprocessors, digital signal processors (DSPs) and processors based on a multi-core processor architecture, as non-limiting examples.

[0050] By utilizing exemplary embodiments of the invention, unlike with other prior art techniques supporting simultaneous transmission of ACK/NACK and SR, SR, ACK/NACK and CQI performance can be maintained with very little, if any, change.

[0051] In many cases, it may be possible to configure periodic CQI and periodic SR into different subframes. In such cases, the performance degradation caused by dropping CQI is estimated to be very marginal.

[0052] Furthermore, accepted modulation options may be utilized in conjunction with exemplary embodiments of the invention. That is, there is no need to specify separate modulation or multiplexing options for positive SR versus negative SR. Existing data-non-associated signaling can be maintained as similar as possible with both positive SR and negative SR. Furthermore, no changes are needed for CM properties.
