Abstract
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus is a UE. The UE receives, from a base station, a measurement configuration for measuring cross-link interference (CLI) in a subband full-duplexing (SBFD) slot and a reporting configuration for reporting the CLI. The UE performs measurements of the CLI on measurement resources indicated by the measurement configuration. The UE reports an indication of the measured CLI to the base station according to the reporting configuration.
Claims19
A method of wireless communication of a user equipment (UE), comprising:
- receiving, from a base station, a measurement configuration for measuring cross-link interference (CLI) in a subband full-duplexing (SBFD) slot having an uplink subband and a downlink subband that do not overlap and that reside within a same component carrier, the uplink subband and the downlink subband being separated by a guardband, wherein frequency resources of the SBFD slot are shared for both downlink transmissions and uplink transmissions, and a reporting configuration for reporting the CLI;
- performing measurements of the CLI on measurement resources indicated by the measurement configuration, wherein the measurement configuration specifies a cross-correlation sequence, the measurement resources comprise a reference signal resource configured in the SBFD slot, and the performing measurements comprises:
- receiving a sequence of signals on the reference signal resource in the SBFD slot;
- and
- determining the CLI based on a correlation of the specified cross-correlation sequence with the received sequence of signals or a difference between the received sequence of signals and an expected received signal sequence;
- and
- reporting an indication of the measured CLI to the base station according to the reporting configuration.
An apparatus for wireless communication, the apparatus being a user equipment (UE), comprising:
- a memory;
- and
- at least one processor coupled to the memory and configured to:
- receive, from a base station, a measurement configuration for measuring cross-link interference (CLI) in a subband full-duplexing (SBFD) slot having an uplink subband and a downlink subband that do not overlap and that reside within a same component carrier, the uplink subband and the downlink subband being separated by a guardband, wherein frequency resources of the SBFD slot are shared for both downlink transmissions and uplink transmissions, and a reporting configuration for reporting the CLI;
- perform measurements of the CLI on measurement resources indicated by the measurement configuration, wherein the measurement configuration specifies a cross-correlation sequence, the measurement resources comprise a reference signal resource configured in the SBFD slot, and to perform the measurements, the at least one processor is configured to:
- receive a sequence of signals on the reference signal resource in the SBFD slot;
- and
- determine the CLI based on a correlation of the specified cross-correlation sequence with the received sequence of signals or a difference between the received sequence of signals and an expected received signal sequence;
- and
- report an indication of the measured CLI to the base station according to the reporting configuration.
A non-transitory computer-readable medium storing computer executable code for wireless communication of a user equipment (UE), comprising code to:
- receive, from a base station, a measurement configuration for measuring cross-link interference (CLI) in a subband full-duplexing (SBFD) slot having an uplink subband and a downlink subband that do not overlap and that reside within a same component carrier, the uplink subband and the downlink subband being separated by a guardband, wherein frequency resources of the SBFD slot are shared for both downlink transmissions and uplink transmissions, and a reporting configuration for reporting the CLI;
- perform measurements of the CLI on measurement resources indicated by the measurement configuration, wherein the measurement configuration specifies a cross-correlation sequence, the measurement resources comprise a reference signal resource configured in the SBFD slot, and the code to perform the measurements comprises code to:
- receive a sequence of signals on the reference signal resource in the SBFD slot;
- and
- determine the CLI based on a correlation of the specified cross-correlation sequence with the received sequence of signals or a difference between the received sequence of signals and an expected received signal sequence;
- and
- report an indication of the measured CLI to the base station according to the reporting configuration.
