Abstract
Method and apparatus for sidelink assisted interference cancellation. The apparatus receives a set of uplink transmission parameters of a second UE in a neighbor cell. The apparatus performs interference cancellation of an uplink transmission of the second UE on a downlink transmission received from a serving cell. The interference cancellation based at least on the set of uplink transmission parameters of the second UE. The apparatus may provide, to a base station, an indication indicating support for the interference cancellation. The apparatus may indicate, to the base station, a type of interference cancellation operation to be performed by the first UE.
Claims24
An apparatus for wireless communication at a first user equipment (UE), comprising:
- memory;
- at least one transceiver;
- and
- at least one processor, communicatively connected to the memory and the at least one transceiver, the at least one processor configured to:
- receive, from a second UE, in a sidelink transmission between the first UE and the second UE, a set of uplink transmission parameters of the second UE in a neighbor cell;
- and
- perform interference cancellation of an uplink transmission of the second UE on a downlink transmission received from a serving cell, the interference cancellation based at least on the set of uplink transmission parameters of the second UE received in the sidelink transmission, wherein the set of uplink transmission parameters of the second UE corresponds to the uplink transmission scheduled for the second UE in a downlink slot for the first UE.
An apparatus for wireless communication to a first user equipment (UE) in a first cell, comprising:
- memory;
- at least one transceiver;
- and
- at least one processor, communicatively connected to the memory and the at least one transceiver, the at least one processor configured to:
- obtain, from a base station associated with a second cell, a set of uplink transmission parameters of a second UE in the second cell, wherein the first cell is different from the second cell;
- and
- transmit the set of uplink transmission parameters of the second UE to the first UE in the first cell, wherein the set of uplink transmission parameters of the second UE corresponds to an uplink transmission scheduled for the second UE in a downlink slot for the first UE.
A method of wireless communication at a first user equipment (UE), comprising:
- receiving, from a second UE, in a sidelink transmission between the first UE and the second UE, a set of uplink transmission parameters of the second UE in a neighbor cell;
- and
- performing interference cancellation of an uplink transmission of the second UE on a downlink transmission received from a serving cell, the interference cancellation based at least on the set of uplink transmission parameters of the second UE received in the sidelink transmission, wherein the set of uplink transmission parameters of the second UE corresponds to the uplink transmission scheduled for the second UE in a downlink slot for the first UE.
A method of wireless communication to a first user equipment (UE) in a first cell comprising:
- obtaining, from a base station associated with a second cell, a set of uplink transmission parameters of a second UE in the second cell, wherein the first cell is different from the second cell;
- and
- transmitting the set of uplink transmission parameters of the second UE to the first UE in the first cell, wherein the set of uplink transmission parameters of the second UE corresponds to the uplink transmission scheduled for the second UE in a downlink slot for the first UE.
