Abstract
A User Equipment (UE) configured to control lengths of one or more monitoring cycles of the UE based, at least in part on a range of a discontinuous reception (DRX) cycle and one or more power conditions of the UE. The monitoring cycle is used to select a beam for transmission by the UE. The DRX cycle is used by the UE during RRC_INACTIVE state and the range of the DRX cycle determines one or more beam correspondence conditions.
Claims15
A User Equipment (UE) comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the UE at least to perform:
- controlling lengths of one or more monitoring cycles of the UE based, at least in part on a range of a discontinuous reception (DRX) cycle and one or more power conditions of the UE, wherein the monitoring cycle is used to select a beam for transmission by the UE;
- and
- wherein (i) the DRX cycle is used by the UE during an RRC_INACTIVE state and the range of the DRX cycle determines one or more beam correspondence conditions and (ii) the UE is able to meet the one or more beam correspondence conditions during the RRC_INACTIVE state by using a gyroscope to estimate a rotation of the UE in order to determine whether a previously selected beam remains valid for transmission by the UE.
A method comprising:
- controlling lengths of one or more monitoring cycles of a user equipment (UE) based, at least in part on a range of a discontinuous reception (DRX) cycle and one or more power conditions of the UE, wherein the monitoring cycle is used to select a beam for transmission by the UE;
- and
- wherein (i) the DRX cycle is used by the UE during an RRC_INACTIVE state and the range of the DRX cycle determines one or more beam correspondence conditions and (ii) the UE is able to meet the one or more beam correspondence conditions during the RRC_INACTIVE state by using a gyroscope to estimate a rotation of the UE in order to determine whether a previously selected beam remains valid for transmission by the UE.
A non-transitory computer readable storage medium comprising a computer program comprising computer program instructions that, when executed by processing circuitry, cause;
- controlling lengths of one or more monitoring cycles of a user equipment (UE) based, at least in part on a range of a discontinuous reception (DRX) cycle and one or more power conditions of the UE, wherein the monitoring cycle is used to select a beam for transmission by the UE;
- and
- wherein (i) the DRX cycle is used by the UE during an RRC_INACTIVE state and the range of the DRX cycle determines one or more beam correspondence conditions and (ii) the UE is able to meet the one or more beam correspondence conditions during the RRC_INACTIVE state by using a gyroscope to estimate a rotation of the UE in order to determine whether a previously selected beam remains valid for transmission by the UE.
