Uplink transmission for multi-panel operation
Methods, systems, and storage media are described for uplink transmission for multi-panel operation. Other embodiments may be described and/or claimed.
1. An apparatus comprising:
memory to store panel index information to indicate an antenna port group that a user equipment (UE) is to use for a physical uplink control channel (PUCCH) signal or a physical uplink shared channel (PUSCH); and
processing circuitry, coupled with the memory, to:
retrieve the panel index information from the memory, wherein the panel index information indicates a number of beams that can be simultaneously transmitted by the UE for the PUCCH signal or the PUSCH signal;
generate a message that includes the panel index information; and
encode the message for transmission to the UE.
2. The apparatus of claim 1 , wherein the processing circuitry is further to receive, from the UE, the PUCCH signal or the PUSCH signal in accordance with the panel index information.
3. The apparatus of claim 1 , wherein the message is to be transmitted via radio resource control (RRC) signaling or medium access layer (MAC) Control Element (CE) signaling.
4. The apparatus of claim 1 , wherein the processing circuitry is to derive the panel index information from a sounding reference signal (SRS) resource.
5. The apparatus of claim 1 , wherein the panel index information indicates a maximum number of beams that can be simultaneously transmitted by the UE.
6. The apparatus of claim 1 , wherein the panel index information is corresponds to a sounding reference signal (SRS) resource, a synchronization signal block (SSB) resource, or a channel state information-reference signal (CSI-RS) resource.
7. The apparatus of claim 1 , wherein the panel index information is to indicate a respective power control parameter for each respective panel.
8. One or more non-transitory, computer-readable media storing instructions, that, when executed by one or more processors, cause a user equipment (UE) to:
receive a configuration message that includes panel index information to indicate an antenna port group of the UE for transmitting a message, wherein the message is a physical uplink control channel (PUCCH) message or a physical uplink shared channel (PUSCH) message, and wherein the panel index information indicates a number of beams that can be simultaneously transmitted by the UE for the PUCCH message or the PUSCH message; and
encode the message for transmission in accordance with the panel index information.
9. The one or more non-transitory, computer-readable media of claim 8 , wherein the instructions are further to cause the UE to:
transmit an indication of a first uplink control information (UCI) type and a second UCI type via PUCCH using a first panel; and
transmit an indication of the second UCI type via PUCCH using a second panel.
10. The one or more non-transitory, computer-readable media of claim 9 , wherein the first UCI type is a hybrid automatic request-acknowledge (HARQ-ACK), and the second UCI type is a channel state information (CSI) report or scheduling request (SR).
11. The one or more non-transitory, computer-readable media of claim 8 , wherein the configuration message is received via radio resource control (RRC) signaling or medium access layer (MAC) Control Element (CE) signaling.
12. The one or more non-transitory, computer-readable media of claim 8 , wherein the panel index information is derived from a sounding reference signal (SRS) resource.
13. The one or more non-transitory, computer-readable media of claim 8 , wherein the panel index information indicates a maximum number of beams that can be simultaneously transmitted by the UE.
14. The one or more non-transitory, computer-readable media of claim 8 , wherein the panel index information corresponds to a sounding reference signal (SRS) resource, a synchronization signal block (SSB) resource, or a channel state information-reference signal (CSI-RS) resource.
15. The one or more non-transitory, computer-readable media of claim 8 , wherein the panel index information is to indicate a respective power control parameter for each respective panel.
16. One or more non-transitory, computer-readable media storing instructions, that, when executed by one or more processors, cause a user equipment (UE) in a cellular communications network to:
determine a configuration message that includes panel index information indicating an antenna port group of the UE for transmitting a message, wherein the configuration message corresponds to a channel state information reference signal (CSI-RS), and wherein the panel index information indicates a number of beams that can be simultaneously transmitted by the UE for the message; and
encode the configuration message for transmission to a base station in the cellular communications network.
17. The one or more non-transitory, computer-readable media of claim 16 , wherein the message comprises one of a physical uplink control channel (PUCCH) message or a physical uplink shared channel (PUSCH) message, and wherein the PUCCH message or the PUSCH message is transmitted in accordance with the panel index information.
18. The one or more non-transitory, computer-readable media of claim 16 , wherein the message is to be transmitted via radio resource control (RRC) signaling or medium access layer (MAC) Control Element (CE) signaling.
19. The one or more non-transitory, computer-readable media of claim 16 , wherein the panel index information indicates a maximum number of beams that can be simultaneously transmitted by the UE.
20. The one or more non-transitory, computer-readable media of claim 16 , wherein the panel index information corresponds to a sounding reference signal (SRS) resource, a synchronization signal block (SSB) resource, or a channel state information-reference signal (CSI-RS) resource.
