Abstract (en)
[origin: WO2022241706A1] In some wireless communication scenarios, it may be intended that a user equipment (UE) is to transmit control information on multiple carriers, with each carrier carrying respective control information associated with a respective different TRP and/or cell and/or cell group. The UE can implement multiple transmitter chains, but the provision of multiple transmitter chains is expensive. Embodiments are disclosed in which a UE instead implements a single transmitter chain for transmitting control information associated with two different TRPs, cells, and/or cell groups. The control information is time-division multiplexed, with various rules implemented in different scenarios, such as when the control information overlaps in time.
