Abstract
A user equipment (UE) is disclosed. The UE includes a processor configured to transmit a rank indicator (RI) using one of an assigned periodic RI reporting resource that precisely aligns with the start on an on-duration of a discontinuous reception (DRX) operation mode of the UE and a first assigned periodic RI reporting resource after the start of the on-duration.
Claims18
A user equipment (UE), comprising:
- a transmitter;
- a receiver;
- and
- one or more processors configured to:
- control the receiver a resource configuration, the resource configuration indicating a periodic reporting resource for transmitting rank indicators (RIs);
- control the receiver in the UE to have an active time, wherein the active time includes at least a time period corresponding to an on duration and a time period when an inactivity timer is running;
- control the transmitter to transmit an RI using the RI reporting resource that immediately follows a beginning of the on duration;
- control the transmitter to transmit an RI using each subsequent RI reporting resource until an end of the active time;
- and
- control the transmitter to discontinue transmission of RI at the end of the active time.
A method for user equipment (UE) including a receiver and a transmitter, comprising:
- controlling the receiver to receive a resource configuration, the resource configuration indicating a periodic reporting resource for transmitting rank indicators (RIs);
- controlling the receiver in the UE to have an active time, wherein the active time includes at least a time period corresponding to an on duration and a time period when an inactivity timer is running;
- controlling the transmitter to transmit an RI using the RI reporting resource that immediately follows a beginning of the on duration;
- controlling the transmitter to transmit an RI using each subsequent RI reporting resource until an end of the active time;
- and
- controlling the transmitter to discontinue transmission of RI at the end of the active time.
A computer program product encoded on a non-transitory medium, the product comprising computer readable instructions for causing one or more processors to perform operations comprising:
- controlling a receiver to receive a resource configuration, the resource configuration indicating a periodic reporting resource for transmitting rank indicators (RIs);
- controlling the receiver in the UE to have an active time, wherein the active time includes at least a time period corresponding to an on duration and a time period when an inactivity timer is running;
- controlling a transmitter to transmit an RI using the RI reporting resource that immediately follows a beginning of the duration;
- controlling the transmitter to transmit an RI using each subsequent RI reporting resource until an end of the active time;
- and
- controlling the transmitter to discontinue transmission of RI at the end of the active time.
