NETWORK SIDE DEVICE, USER EQUIPMENT, AND SPECTRUM SHARING METHOD THEREOF

Description

TECHNICAL FIELD

[0001] The present invention relates to the field of communications technologies, and in particular, to a network side device, user equipment, and a spectrum sharing method thereof.

BACKGROUND

[0002] In the field of communications technologies, a spectrum resource is an important resource for a wireless communications system. During deployment by using an existing access technology, a corresponding frequency needs to be determined first. During deployment of a network by using an access technology, different frequencies are selected for an existing Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS) and a Long Term Evolution technology (Long Term Evolution, LTE) system, so as to perform data transmission by using a spectrum resource. During data transmission of an existing system, a case of a shortage of spectrum resources that is caused by excessively heavy load of the system or a waste of spectrum resources that is caused by excessively light load of the system usually occurs, which easily results in unbalanced use of spectrum resources.

[0003] In US 2011/0269456 A1, a wireless communication device have a first network role associated with a first identity and a second network role associated with a second identity. The two identities can share some resource, such as baseband equipment and/or data. The wireless communication device includes a communication processing subsystem which supports different identities using common hardware to operate on different identities. The wireless device may have more than two identities and may be able to access more than two networks at substantially the same time. For example, this can enable a user to appear as different persons on a network using the same wireless device.

Apparently, the described embodiments are merely some but not all of the embodiments of the present invention.

[0009] Refer to FIG. 1, which is a schematic structural diagram of a communications system according to a first embodiment of the present invention. The communications system includes user equipment 10 and a network side device 11. The network side device 11 performs data transmission with the user equipment 10 by using a first system or a second system.

[0010] In this embodiment, the network side device 11 is provided with a shared frequency of the first system and the second system, so that the first system performs data transmission by using the shared frequency, or the second system performs data transmission by using the shared frequency. Optionally, the first system is a UMTS, and the second system is an LTE system. In other embodiments, the first system is an LTE system, and the second system is a UMTS. Alternatively, the first system and the second system may be a combination of an LTE system, a UMTS, and a Global System for Mobile Communications (Global System for Mobile Communications, GSM) and other communications systems; for example, the first system is a GSM, and the second system is a UMTS.

[0011] The network side device 11 includes a first network device 12 and a second network device 13. When the network side device 11 performs data transmission with the user equipment 10, the second network device 13 first acquires load information of the first system and load information of the second system, and acquires a cycle period of the shared frequency of the first system and the second system, and the second network device 13 then obtains time slice allocation information according to the load information of the first system, the load information of the second system, and the cycle period, where the time slice allocation information includes a first time slice and a second time slice. In this embodiment, the second network device 13 preferably slices the cycle period into the first time slice and the second time slice according to a proportion of load of the first system to load of the second system. For example, the proportion of the load of the first system to the load of the second system is 1:2, so that a proportion of the first time slice to the second time slice is 1:2. In addition, the second network device 13 determines valid times of the first time slice and the second time slice within the cycle period according to the proportion of the load of the first system to the load of the second system, where the valid time may be a specific time point. In other embodiments, the second network device 13 obtains the time slice allocation information according to the load information of the first system, the load information of the second system, and the cycle period in other manners, for example, by using a formula algorithm.

[0012] After the second network device 13 generates the time slice allocation information, the second network device 13 sends the time slice allocation information to the first network device 12 or the second network device 13, and the first network device 12 or the second network device 13 sends the time slice allocation information to the user equipment 10.

la réception d'informations d'indication de qualité de canal, CQI, ou d'informations d'indication de commande de précodage, PCI, à partir de l'équipement utilisateur ; et

la surveillance, à l'aide des informations de CQI ou des informations de PCI, de la qualité de canal de la transmission de données réalisée en utilisant la fréquence partagée.

6. Procédé selon la revendication 4 ou 5, dans lequel le premier système et le second système sont une combinaison de deux systèmes dans les systèmes suivants : un système d'évolution à long terme, LTE, un système universel de télécommunications mobiles, UMTS, et un système global de communications mobiles, GSM, et d'autres systèmes de communication.

7. Equipement utilisateur, comprenant :

une unité de réception (101), configurée pour recevoir, à partir d'un dispositif de réseau, des informations d'attribution de tranches de temps d'une période de cycle d'une fréquence partagée entre un premier système et un second système, dans lequel les informations d'attribution de tranches de temps comprennent des informations de découpage temporel qui découpent la période de cycle en une première tranche de temps pour le premier système et une seconde tranche de temps pour le second système ; et

l'équipement utilisateur étant caractérisé en outre par

une unité d'envoi (103), configurée pour envoyer des données à la première tranche de temps à l'aide du premier système et en utilisant la fréquence partagée, et envoyer des données à la seconde tranche de temps à l'aide du second système et en utilisant la fréquence partagée.

8. Equipement utilisateur selon la revendication 7, comprenant en outre :

une unité de traitement (102), configurée pour générer des informations d'indication de qualité de canal, CQI, ou des informations d'indication de commande de précodage, PCI, en fonction des informations d'attribution de tranches de temps ;

dans lequel l'unité d'envoi est configurée en outre pour envoyer les informations de CQI ou de PCI à un dispositif de réseau, dans lequel le dispositif de réseau est un premier dispositif de réseau ou un second dispositif de réseau.

9. Dispositif côté réseau, comprenant :

une unité de traitement (122, 132), configurée pour acquérir une période de cycle d'une fréquence partagée entre un premier système et un second système, et obtenir des informations d'attribution de tranches de temps de la période de cycle, dans lequel les informations d'attribution de tranches de temps comprennent des informations de découpage temporel qui découpent la période de cycle en une première tranche de temps et une seconde tranche de temps,

le dispositif de réseau étant caractérisé en outre en ce que la première tranche de temps est destinée à la transmission, par un équipement utilisateur, de données sur la fréquence partagée à l'aide du premier système, la deuxième tranche de temps est destinée à la transmission, par l'équipement utilisateur, de données sur la fréquence partagée à l'aide du second système ; et

une unité d'envoi (123, 133), configurée pour envoyer les informations d'attribution de tranches de temps à l'équipement utilisateur.

10. Dispositif côté réseau selon la revendication 9, comprenant en outre :

une unité de réception, configurée pour recevoir des informations d'indication de qualité de canal, CQI, ou des informations d'indication de commande de précodage, PCI, à partir de l'équipement utilisateur ; et

l'unité de traitement est configurée en outre pour surveiller, à l'aide des informations de CQI ou des informations de PCI, la qualité de canal de la transmission de données réalisée en utilisant la fréquence partagée.
