User equipment capability signaling
A user equipment (UE) configured for signaling UE capability is described. The UE includes a processor and instructions stored in memory that is in electronic communication with the processor. The UE sends an indicator regarding whether the UE can support different time division duplex (TDD) configurations on different bands for a band combination. The UE also sends an indicator regarding whether the UE can support concurrent transmission and reception on different bands for the band combination. The UE additionally sends an indicator regarding whether the UE can support different uplink timing adjustments for the band combination.
1. A user equipment (UE) configured for signaling UE capability, comprising:
a processor;
memory in electronic communication with the processor; and
instructions stored in the memory, the instructions being executable to:
send, to an evolved Node B (eNB), a radio resource control (RRC) message including capability information of the UE, wherein
the capability information includes specific information that is configured to indicate, for each band combination of a plurality of band combinations, whether the UE supports different timing adjustments; and
the capability information is configurable to indicate that (i) the UE supports different timing adjustments for a first band combination of the plurality of band combinations, and (ii) the UE does not support different timing adjustments for a second band combination of the plurality of band combinations.
2. An evolved Node B (eNB) configured for receiving signaling for user equipment (UE) capability, comprising:
a processor;
memory in electronic communication with the processor; and
instructions stored in the memory, the instructions being executable to:
receive, from a UE, a radio resource control (RRC) message including capability information of the UE, wherein the capability information includes specific information that is configured to indicate, for each band combination of a plurality of band combinations, whether the UE supports different timing adjustments, and
the capability information is configurable to indicate that (i) the UE supports different timing adjustments for a first band combination of the plurality of band combinations, and (ii) the UE does not support different timing adjustments for a second band combination of the plurality of band combinations.
3. A method for signaling user equipment (UE) capability from a UE, comprising:
sending, to an evolved Node B (eNB), a radio resource control (RRC) message including capability information of the UE, wherein the capability information includes specific information that is configured to indicate, for each band combination of a plurality of band combinations, whether the UE supports different timing adjustments; wherein
the capability information is configurable to indicate that (i) the UE supports different timing adjustments for a first band combination of the plurality of band combinations, and (ii) the UE does not support different timing adjustments for a second band combination of the plurality of band combinations.
4. A method for receiving signaling for user equipment (UE) capability by an evolved Node B (eNB), comprising:
receiving, from a UE, a radio resource control (RRC) message including capability information of the UE, wherein the capability information includes specific information that is configured to indicate, for each band combination of a plurality of band combinations, whether the UE supports different timing adjustments; wherein
the capability information is configurable to indicate that (i) the UE supports different timing adjustments for a first band combination of the plurality of band combinations, and (ii) the UE does not support different timing adjustments for a second band combination of the plurality of band combinations.
