摘要
A design is provided for spatially multiplexing uplink channels. A user equipment (UE) detects that a Physical Uplink Control Channel (PUCCH) and a Sounding Reference Signal (SRS) are to be transmitted simultaneously. The UE decides to spatially multiplex the PUCCH and the SRS for simultaneous transmission via different sets of one or more antennas. The UE determines time and frequency resources for the PUCCH and the SRS to avoid collision of at least a portion of the PUCCH with the SRS. The UE transmits the spatially multiplexed PUCCH and SRS using the determined time and frequency resources.

Additionally or alternatively, the puncturing pattern depends on the PUCCH format. For example, the UE punctures SRS resources if colliding with PUCCH formats 0 and 2, and does not puncture the SRS resources if colliding with PUCCH formats 1, 3, or 4.
In certain aspects, when the PUCCH (or at least the UCI portion of the PUCCH) is configured to collide with SRS, the UE may rate match the SRS around the PUCCH (or at least the UCI) transmission. For example, following the same example as used for explaining puncturing, rate matching means that, UE re-generates another SRS signal of length 6, e.g., a1, . . . ,a6 based on the new length of the SRS, and transmits a1, . . . ,a6 on the 6 non-overlapping REs.
