Abstract
This disclosure provides systems, methods, and devices for wireless communication that support a bandwidth part (BWP) switch request. In a first aspect, a method of wireless communication includes receiving downlink control information (DCI) that indicates a BWP switch request. The method also includes, prior to execution of a BWP switch based on the BWP request, determining whether a first value of a first field of the DCI is valid. Other aspects and features are also claimed and described.
Claims30
A method of wireless communication performed by a user equipment (UE), the method comprising:
- receiving a radio resource control (RRC) signaling that comprises one or more non-bandwidth part (non-BWP) specific parameters;
- receiving, on a first BWP, downlink control information (DCI) that indicates one or more resource assignments to the UE and a BWP switch request;
- validating a resource grant by comparing one or more fields of the DCI with the one or more non-BWP specific parameters;
- and
- switching to a second BWP or maintaining the first BWP based on a result of the validating;
- wherein the one or more non-BWP specific parameters indicates a number of layers, a carrier indicator, or combination thereof.
A user equipment (UE) comprising:
- a memory storing processor-readable code;
- and
- at least one processor coupled to the memory, the at least one processor configured to execute the processor-readable code to cause the at least one processor to:
- receive a radio resource control (RRC) signaling that comprises one or more non-bandwidth part (non-BWP) specific parameters;
- receive, on a first BWP, downlink control information (DCI) that indicates one or more resource assignments to the UE and a BWP switch request;
- validate a resource grant by comparing one or more fields of the DCI with the one or more non-BWP specific parameters;
- and
- switch to a second BWP or maintain the first BWP based on a result of the validating;
- wherein the one or more non-BWP specific parameters indicates a number of layers, a carrier indicator, or combination thereof.
An apparatus configured for wireless communication, the apparatus comprising:
- means for receiving a radio resource control (RRC) signaling that comprises one or more non-bandwidth part (non-BWP) specific parameters;
- means for receiving, on a first BWP, downlink control information (DCI) that indicates one or more resource assignments to the UE and a BWP switch request;
- means for validating a resource grant by comparing one or more fields of the DCI with the one or more non-BWP specific parameters;
- and
- means for switching to a second BWP or maintaining the first BWP based on a result of the validating;
- wherein the one or more non-BWP specific parameters indicates a number of layers, a carrier indicator, or combination thereof.
A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:
- receiving a radio resource control (RRC) signaling that comprises one or more non-bandwidth part (non-BWP) specific parameters;
- receiving, on a first BWP, downlink control information (DCI) that indicates one or more resource assignments to the UE and a BWP switch request;
- validating a resource grant by comparing one or more fields of the DCI with the one or more non-BWP specific parameters;
- and
- switching to a second BWP or maintaining the first BWP based on a result of the validating;
- wherein the one or more non-BWP specific parameters indicates a number of layers, a carrier indicator, or combination thereof.
