Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a semi-persistent scheduling (SPS) configuration message from a base station, the SPS configuration message containing at least one SPS parameter for downlink SPS communications over a shared radio frequency spectrum band. The UE may identify, based on the SPS configuration, one or more subframes or slots allocated for the downlink SPS communications. The UE may perform the downlink SPS communications during the one or more subframes or slots and according to the SPS configuration.
Claims49
A method for wireless communications, comprising:
- receiving a semi-persistent scheduling (SPS) configuration message from a base station, the SPS configuration message comprising at least one SPS parameter for downlink SPS communications over a shared radio frequency spectrum band;
- identifying, based at least in part on the SPS configuration, one or more subframes or slots allocated for the downlink SPS communications;
- and
- performing the downlink SPS communications during the one or more subframes or slots and according to the SPS configuration.
A method for wireless communications, comprising:
- identifying one or more user equipment (UE) for performing downlink semi-persistent scheduling (SPS) communications over a shared radio frequency spectrum band;
- transmitting an SPS configuration message to the one or more UEs that comprises at least one SPS parameter for the downlink SPS communications over the shared radio frequency spectrum band;
- and
- performing the downlink SPS communications during one or more subframes or slots according to the SPS configuration.
An apparatus for wireless communications, comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory and executable by the processor to:
- receive a semi-persistent scheduling (SPS) configuration message from a base station, the SPS configuration message comprising at least one SPS parameter for downlink SPS communications over a shared radio frequency spectrum band;
- identify, based at least in part on the SPS configuration, one or more subframes or slots allocated for the downlink SPS communications;
- and
- perform the downlink SPS communications during the one or more subframes or slots and according to the SPS configuration.
An apparatus for wireless communications, comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, wherein the instructions are executable by the processor to:
- identify one or more user equipment (UE) for performing downlink semi-persistent scheduling (SPS) communications over a shared radio frequency spectrum band;
- transmit an SPS configuration message to the one or more UEs that comprises at least one SPS parameter for the downlink SPS communications over the shared radio frequency spectrum band;
- and
- perform the downlink SPS communications during one or more subframes or slots according to the SPS configuration.
