In an aspect, the remaining portion includes uplink control information (UCI).
Certain aspects provide a method for wireless communication a User Equipment (UE). The method generally includes deciding to spatially multiplex a Physical Uplink Shared Channel (PUSCH) and a Sounding Reference Signal (SRS) for simultaneous transmission via different sets of one or more antennas; determining that Uplink Control Information (UCI) is to be transmitted using resources assigned for the PUSCH, and that at least a portion of time and frequency resources for the PUSCH is to be used for transmission of the SRS; determining a resource mapping pattern for mapping the UCI to the PUSCH resources, wherein the resource mapping pattern avoids collision of the UCI with the SRS; mapping the UCI to the PUSCH resources based on the resource mapping pattern; and transmitting the spatially multiplexed PUSCH and the SRS after the mapping.
In an aspect, the mapping includes mapping at least a portion of UCI bits indicating acknowledgement/negative acknowledgement (ACK/NACK) using the PUSCH resources not to be used for the SRS.
In an aspect, the mapping includes, after mapping the at least a portion of the UCI bits indicating ACK/NACK, mapping a remaining portion of the UCI bits indicating ACK/NACK and at least a portion of the UCI bits indicating channel state indication (CSI) using the PUSCH resources to be used for SRS.
In an aspect, the mapping includes mapping UCI bits indicating acknowledgement/negative acknowledgement (ACK/NACK) before mapping the UCI bits indicating channel state indication (CSI).
