Abstract
Various embodiments herein may relate to default beam operations for uplink transmissions. In particular, some embodiments are directed to default beam operations for physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH) or sounding reference signal (SRS) transmissions in multi-transmission reception point (TRP) scenarios. Other embodiments may be disclosed or claimed.
Claims19
-18. (canceled)
An apparatus comprising:
- memory to store configuration information for an uplink transmission by a user equipment (UE);
- and
- processing circuitry, coupled with the memory, to:
- retrieve the configuration information from the memory, wherein the configuration information includes an indication that a default beam operation is enabled for the uplink transmission and that physical downlink control channel (PDCCH) repetitions are enabled for multi-transmission reception point (TRP) operation;
- and
- encode a message for transmission to the UE that includes the configuration information.
One or more non-transitory computer-readable media storing instructions that, when executed by one or more processors, cause a next-generation NodeB (gNB) to:
- determine configuration information for an uplink transmission by a user equipment (UE), wherein the configuration information includes an indication that a default beam operation is enabled for the uplink transmission and that physical downlink control channel (PDCCH) repetitions are enabled for multi-transmission reception point (TRP) operation;
- and
- encode a message for transmission to the UE that includes the configuration information, wherein the configuration information in the message is included in downlink control information (DCI).
A user equipment (UE) comprising:
- memory to store a configuration message received from a next-generation NodeB (gNB), wherein the configuration message includes configuration information for an uplink transmission by the UE, wherein the configuration information includes an indication that a default beam operation is enabled for the uplink transmission and that physical downlink control channel (PDCCH) repetitions are enabled for multi-transmission reception point (TRP) operation;
- and
- one or more processors to encode an uplink message for transmission based on the configuration information.
