Abstract
A control channel transmission may include information for downlink transmissions, and another control channel, such as a physical micro sleep indicator channel (PMSICH), may include information for uplink transmissions that a user equipment (UE) may use to enter a power-saving micro sleep state. A base station may drop PMSICH transmissions in the event that downlink resources are constrained. A UE that receives a PMSICH transmission may determine an uplink transmission duration, and enter a micro sleep state for all or a portion of the uplink transmission duration.
Claims30
A method for wireless communication, comprising:
- identifying a control region in a downlink transmission;
- demodulating the identified control region of the downlink transmission;
- identifying a micro sleep indicator received in the control region that indicates a micro sleep state may be entered for at least a portion of one or more transmission time intervals (TTIs);
- and
- entering the micro sleep state for at least the portion of the one or more TTIs based at least in part on the micro sleep indicator.
A method for wireless communication, comprising:
- identifying a downlink transmission duration for downlink transmissions to one or more user equipment (UEs) and an uplink transmission duration for uplink transmissions from the one or more UEs;
- determining a micro sleep indicator that indicates the one or more UEs may enter a micro sleep state for at least a portion of the downlink transmission duration, the uplink transmission duration, or any combination thereof;
- and
- transmitting the micro sleep indicator to the one or more UEs in a control channel.
An apparatus for wireless communication, comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
- identify a control region in a downlink transmission;
- demodulate the identified control region of the downlink transmission;
- identify a micro sleep indicator received in the control region that indicates a micro sleep state may be entered for at least a portion of one or more transmission time intervals (TTIs);
- and
- enter the micro sleep state for at least the portion of the one or more TTIs based at least in part on the micro sleep indicator.
