Abstract
A first UE may transmit, to a network entity, UE capability of the first UE. The first UE may further receive, from the network entity, a first DCI that schedules a downlink transmission for the first UE and provides IC information for an uplink transmission for a second UE scheduled to at least partially overlap in time and frequency with the downlink transmission. The first UE may further decode the downlink transmission based on at least a portion of the IC information for the uplink transmission.
Claims35
An apparatus for wireless communication at a first user equipment (UE), comprising:
- memory;
- and
- one or more processors coupled to the memory and configured to cause the first UE to:
- receive, from a network entity, a single downlink control information (DCI) that includes:
- a first indicator of a schedule for a downlink transmission associated with the first UE, and
- a second indicator that provides interference cancellation (IC) information for an uplink transmission associated with a second UE, wherein the uplink transmission is scheduled to at least partially overlap in time and frequency with the downlink transmission, wherein the network entity does not comprise the second UE;
- and
- decode the downlink transmission based on at least a portion of the IC information for the uplink transmission.
An apparatus for wireless communication at a network entity, comprising:
- memory;
- and
- one or more processors coupled to the memory and configured to cause the network entity to:
- schedule a downlink transmission for a first user equipment (UE) and an uplink transmission for a second UE, wherein the uplink transmission at least partially overlaps in time and frequency with the downlink transmission, wherein the network entity does not comprise the second UE;
- and
- output, to the first UE, a single downlink control information (DCI), wherein the single DCI includes:
- a first indicator of the scheduled downlink transmission for the first UE, and
- a second indicator that provides interference cancellation (IC) information for the scheduled uplink transmission for the second UE.
A method for wireless communication at a first user equipment (UE), comprising:
- receiving, from a network entity, a single downlink control information (DCI) that includes:
- a first indicator of a schedule for a downlink transmission associated with the first UE, and
- a second indicator providing interference cancellation (IC) information for an uplink transmission associated with a second UE, wherein the uplink transmission is scheduled to at least partially overlap in time and frequency with the downlink transmission, wherein the network entity does not comprise the second UE;
- and
- decoding the downlink transmission based on at least a portion of the IC information for the uplink transmission.
A method for wireless communication at a network entity, comprising:
- scheduling a downlink transmission for a first user equipment (UE) and an uplink transmission for a second UE, the uplink transmission at least partially overlapping in time and frequency with the downlink transmission, wherein the network entity does not comprise the second UE;
- and
- outputting, to the first UE, a single downlink control information (DCI), wherein the single DCI includes:
- a first indicator of the scheduled downlink transmission for the first UE, and
- a second indicator providing interference cancellation (IC) information for the scheduled uplink transmission for the second UE.
