Beam management for physical uplink shared channels in dense deployments

A user equipment (UE), comprising:

• communications circuitry capable of connecting to a wireless network,
• a processor, and
• a memory storing instructions which, when executed by the processor, cause the processor to:
• receive one or more downlink transmissions comprising Radio Resource Control (RRC) signaling and Downlink Control Information (DCI) that schedules one or more Physical Uplink Shared Channels (PUSCHs),
• wherein the RRC signaling indicates two Sounding Reference Signal (SRS) resource sets (SRSRS) including a first SRSRS and a second SRSRS,
• wherein the DCI includes a 2-bit SRSRS selection field, a first SRS Resource Indicator (SRI) field, and a second SRI field for non-codebook-based and/or codebook-based PUSCH operation,
• wherein the 2-bit SRSRS selection field indicates one of codepoint values of 0 to 3,
• wherein the codepoint value of 0 indicates that the first SRI field is used to indicate the first SRSRS and that the second SRI field is unused,
• wherein the codepoint value of 1 indicates that the first SRI field is used to indicate the second SRSRS and that the second SRI field is unused,
• wherein the codepoint value of 2 indicates that the first SRI field is used to indicate the first SRSRS and that the second SRI field is used to indicate the second SRSRS,
• wherein the codepoint value of 3 indicates that the first SRI field is used to indicate the first SRSRS and that the second SRI field is used to indicate the second SRSRS, and
• wherein the first SRSRS corresponds to a lower ID than the second SRSRS;
• and
• transmit one or more PUSCH occasions.
