Association of subband full duplex configurations and bandwidth parts
Certain aspects of the present disclosure provide techniques for association of subband full duplex (SBFD) configurations and bandwidth parts (BWP). An example method, performed at a user equipment (UE), generally includes receiving signaling indicating one or more associations between one or more subband full duplex (SBFD) configurations and one or more bandwidth parts (BWPs), determining whether one of the SBFD configurations is applicable to a first BWP based on the associations, and communicating on the first BWP in accordance with the determination.
1 . A method for wireless communication at a user equipment (UE), comprising:
receiving signaling indicating one or more associations between one or more subband full duplex (SBFD) configurations and one or more bandwidth parts (BWPs), wherein:
the signaling comprises radio resource control (RRC) signaling indicating a higher-layer parameter with one or more bits, and
each bit indicates whether one of the one or more SBFD configurations is applicable to a BWP associated with that bit;
determining whether one of the one or more SBFD configurations is applicable to a first BWP based on the one or more associations, the determination based on a bit in the higher-layer parameter associated with the first BWP; and
communicating on the first BWP in accordance with the determination.
2 . The method of claim 1 , wherein the higher-layer parameter is indicated as part of an SBFD configuration of a serving cell configuration.
3 . The method of claim 1 , wherein the higher-layer parameter is indicated as part of a BWP configuration for the first BWP.
4 . The method of claim 1 , further comprising
receiving an update to the higher-layer parameter, wherein the determination is based on the update.
5 . The method of claim 1 , wherein at least one of the higher-layer parameter or the update is received via at least one of RRC signaling, downlink control information (DCI) or a medium access control (MAC) control element (CE).
6 . The method of claim 1 , further comprising
receiving signaling indicating at least one of a switch to a second BWP that is not associated with an SBFD configuration, a release of the one or more SBFD configurations, or an updated SBFD time pattern indicating no SBFD symbols.
7 . The method of claim 1 , wherein the signaling indicates at least one association between an uplink and downlink BWP pair to an SBFD configuration ID.
8 . The method of claim 1 , wherein the one or more SBFD configurations are cell-specific or UE-dedicated.
9 . The method of claim 1 , further comprising
receiving an indication of at least one time pattern indicating time locations for which the one or more SBFD configurations apply.
10 . The method of claim 9 , wherein the indication indicates at least one of: a single time pattern applicable to multiple BWPs, or multiple time patterns applicable to multiple BWPs.
11 . A method for wireless communication at a network entity, comprising:
transmitting signaling indicating one or more associations between one or more subband full duplex (SBFD) configurations and one or more bandwidth parts (BWPs), wherein:
the signaling comprises radio resource control (RRC) signaling indicating a higher-layer parameter with one or more bits, and
each bit indicates whether one of the one or more SBFD configurations is applicable to a BWP associated with that bit;
determining whether one of the one or more SBFD configurations is applicable to a first BWP based on the one or more associations, the determination based on a bit in the higher-layer parameter associated with the first BWP; and
communicating with a user equipment (UE) on the first BWP in accordance with the determination.
12 . The method of claim 11 , wherein the higher-layer parameter is indicated as part of an SBFD configuration of a serving cell configuration.
13 . The method of claim 11 , wherein the higher-layer parameter is indicated as part of a BWP configuration for the first BWP.
14 . The method of claim 11 , further comprising
transmitting an update to the higher-layer parameter, wherein the determination is based on the update.
15 . The method of claim 14 , wherein at least one of the higher-layer parameter or the update is received via at least one of RRC signaling, downlink control information (DCI) or a medium access control (MAC) control element (CE).
16 . The method of claim 11 , further comprising
transmitting signaling indicating at least one of a switch to a second BWP that is not associated with an SBFD configuration, a release of the one or more SBFD configurations, or an updated SBFD time pattern indicating no SBFD symbols.
17 . The method of claim 11 , wherein the signaling indicates at least one association between an uplink and downlink BWP pair to an SBFD configuration ID.
18 . The method of claim 11 , wherein the one or more SBFD configurations are cell-specific or UE-dedicated.
19 . The method of claim 11 , further comprising
transmitting an indication of at least one time pattern indicating time locations for which the one or more SBFD configurations apply.
20 . The method of claim 19 , wherein the indication indicates at least one of: a single time pattern applicable to multiple BWPs, or multiple time patterns applicable to multiple BWPs.
