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.

說(shuō)明書(shū)

In an aspect, detecting that the PUCCH and the SRS are to be transmitted simultaneously includes detecting the SRS is to be transmitted on the same OFDM symbol in a same resource block as the DMRS.

In an aspect, determining the time and frequency resources includes determining a comb pattern for the SRS same as a comb pattern used for the DMRS; and determining the resources for the SRS based on the determined comb pattern on subcarriers not occupied by the DMRS.

In an aspect, detecting that the PUCCH and the SRS are to be transmitted simultaneously includes detecting that at least a remaining portion of the PUCCH and the SRS are configured to be transmitted on a same OFDM symbol of a same resource block.

In an aspect, determining the time and frequency resources includes determining the same OFDM symbol of the same resource block for transmission of the remaining portion and the SRS if the SRS is at least one of X resource blocks wide or Y times wider than the PUCCH.

In an aspect, values of X and Y are determined based on at least one of a SRS use case or a format of the PUCCH.

In an aspect, the value of X and Y are configured via Radio Resource Control (RRC) signaling.

In an aspect, determining the time and frequency resources further includes determining a puncturing pattern for the SRS; and determining the resources for the remaining portion by puncturing resource elements (REs) scheduled for the SRS based on the puncturing pattern.

In an aspect, the puncturing pattern is based on a format of the PUCCH.

In an aspect, the determining further includes rate matching transmission of the SRS around transmission of the remaining portion.
