Abstract
The present disclosure proposes a user equipment (UE) and method for monitoring physical downlink control channel (PDCCH) for small data transmission (SDT) and a network node and method for configuring a UE with downlink (DL) radio resource for PDCCH for SDT. The method at the UE for monitoring PDCCH in downlink (DL) radio resource for SDT in a non-connected state comprises: receiving, from a network node serving the UE, a message indicating the DL radio resource to be monitored by the UE for SDT; and monitoring one or more PDCCHs in the indicated DL radio resource for SDT in the non-connected state.
Claims20
A method at a user equipment (UE) for monitoring Physical Downlink Control Channel (PDCCH) in downlink (DL) radio resource for small data transmission (SDT) in a non-connected state, the method comprising:
- receiving, from a network node serving the UE, a message indicating the DL radio resource to be monitored by the UE for SDT;
- and
- monitoring one or more PDCCHs in the indicated DL radio resource for SDT in the non-connected state, wherein the non-connected state is an RRC_INACTIVE state, and wherein the DL radio resource is indicated in the message by a control resource set (CORESET) field or a CORESET ID field.
A user equipment (UE) for monitoring Physical Downlink Control Channel (PDCCH) in downlink (DL) radio resource for small data transmission (SDT) in a non-connected state, the UE comprising:
- a processor;
- and
- a memory storing instructions which, when executed by the processor, cause the processor to:
- receive from a network node serving the UE, a message indicating a DL radio resource to be monitored by the UE for SDT;
- and
- monitor one or more PDCCHs in the indicated DL radio resource for SDT in the non-connected state, wherein the non-connected state is an RRC_INACTIVE state, and wherein the DL radio resource is indicated in the message by a control resource set (CORESET) field or a CORESET ID field.
A method at a network node for configuring a user equipment (UE) with downlink (DL) radio resource for Physical Downlink Control Channel (PDCCH) for small data transmission (SDT) in a non-connected state, the method comprising:
- transmitting, to the UE, a message indicating the DL radio resource to be monitored by the UE for SDT;
- and
- transmitting, to the UE, one or more PDCCHs for SDT in the indicated DL radio resource, wherein the non-connected state is an RRC_INACTIVE state, and wherein the DL radio resource is indicated in the message by a control resource set (CORESET) field or a CORESET ID field.
