Abstract
Aspects of the present disclosure provided techniques that may be applied in systems that utilize bundled transmissions from a base station (e.g., an eNodeB) to a user equipment (UE), when a user equipment (UE) is in a connected mode of operation. An exemplary method performed by a UE for processing a downlink control channel sent as a bundled transmission over a bundle of subframes, comprises determining when to start monitoring for the control channel; and monitoring for the control channel in a limited number of downlink subframes, based on the determination.
Claims22
A method of processing a control channel by a user equipment (UE), comprising:
- determining when to start monitoring, within an on duration of a discontinuous reception (DRX) operating mode, for a control channel sent as a bundled transmission over a bundle of subframes, wherein:
- the determining is based, at least in part, on a bundling size of the control channel;
- and
- the determining comprises determining multiple possible starting positions for monitoring for the control channel within the on duration, wherein the multiple possible starting positions are separated by at least one transmission time interval (TTI);
- and
- monitoring, based on the determining, for the control channel in a subset of the bundle of subframes.
A method of transmitting a control channel by a base station, comprising:
- providing information to a user equipment (UE) indicating when to start monitoring, within an on duration of a discontinuous reception (DRX) operating mode, for a control channel to be sent as a bundled transmission over a bundle of subframes, where in:
- the information indicates multiple possible starting positions for monitoring for the control channel within the on duration;
- the multiple possible starting positions are based, at least in part, on a bundling size of the control channel;
- and
- the multiple possible starting positions are separated by at least one transmission time interval (TTI);
- and
- sending the control channel as a bundled transmission.
An apparatus for processing a control channel by a user equipment (UE), comprising:
- at least one processor configured to:
- determine when to start monitoring, within an on duration of a discontinuous reception (DRX) operating mode, for a control channel to be sent as a bundled transmission over a bundle of subframes, wherein the at least one processor is configured to:
- determine when to start monitoring based, at least in part, on a bundling size of the control channel;
- and
- determine when to start monitoring by determining multiple possible starting positions for monitoring for the control channel within the on duration, wherein the multiple possible starting positions are separated by at least one transmission time interval (TTI);
- and
- monitor, based on the determining, for the control channel in a subset of the bundle of subframes;
- and
- a memory coupled with the at least one processor.
