Abstract
Aspects present herein relate to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus may receive a first indication of assistance information associated with a Uu DRX configuration and an SL DRX configuration. The apparatus may also transmit a second indication of the assistance information associated with the Uu DRX configuration and the SL DRX configuration. Additionally, the apparatus may receive an indication of the Uu DRX configuration and an indication of the SL DRX configuration.
Claims29
An apparatus for wireless communication at a user equipment (UE), comprising:
- memory;
- and
- at least one processor coupled to the memory and configured to:
- receive a first indication of assistance information associated with a UE-universal mobile telecommunications system terrestrial radio access network (UTRAN) (Uu) discontinuous reception (DRX) configuration and a sidelink (SL) DRX configuration;
- transmit a second indication of the assistance information associated with the Uu DRX configuration and the SL DRX configuration, wherein the assistance information comprises one or more existing SL DRX configurations of at least one other UE;
- and
- receive an indication of the Uu DRX configuration and an indication of the SL DRX configuration, wherein the SL DRX configuration is based on the one or more existing SL DRX configurations and a capability of the UE, and wherein the SL DRX configuration does not overlap with the one or more existing SL DRX configurations.
A method of wireless communication at a user equipment (UE), comprising:
- receiving a first indication of assistance information associated with a UE-universal mobile telecommunications system terrestrial radio access network (UTRAN) (Uu) discontinuous reception (DRX) configuration and a sidelink (SL) DRX configuration;
- transmitting a second indication of the assistance information associated with the Uu DRX configuration and the SL DRX configuration, wherein the assistance information comprises one or more existing SL DRX configurations of at least one other UE;
- and
- receiving an indication of the Uu DRX configuration and an indication of the SL DRX configuration, wherein the SL DRX configuration is based on the one or more existing SL DRX configurations and a capability of the UE, and wherein the SL DRX configuration does not overlap with the one or more existing SL DRX configurations.
An apparatus for wireless communication at a base station, comprising:
- memory;
- and
- at least one processor coupled to the memory and configured to:
- receive, from a user equipment (UE), an indication of assistance information associated with a UE-universal mobile telecommunications system terrestrial radio access network (UTRAN) (Uu) discontinuous reception (DRX) configuration and a sidelink (SL) DRX configuration, wherein the assistance information comprises one or more existing SL DRX configurations of at least one other UE;
- configure the SL DRX configuration and the Uu DRX configuration based on the indication of the assistance information, wherein the SL DRX configuration is based on the one or more existing SL DRX configurations and a capability of the UE, and wherein the SL DRX configuration does not overlap with the one or more existing SL DRX configurations;
- and
- transmit, to the UE, an indication of the SL DRX configuration and an indication of the Uu DRX configuration.
A method of wireless communication at a base station, comprising:
- receiving, from a user equipment (UE), an indication of assistance information associated with a UE-universal mobile telecommunications system terrestrial radio access network (UTRAN) (Uu) discontinuous reception (DRX) configuration and a sidelink (SL) DRX configuration, wherein the assistance information comprises one or more existing SL DRX configurations of at least one other UE;
- configuring the SL DRX configuration and the Uu DRX configuration based on the indication of the assistance information, wherein the SL DRX configuration is based on the one or more existing SL DRX configurations and a capability of the UE, and wherein the SL DRX configuration does not overlap with the one or more existing SL DRX configurations;
- and
- transmitting, to the UE, an indication of the SL DRX configuration and an indication of the Uu DRX configuration.
