Abstract
In embodiments, apparatuses, methods, and storage media may be described for identifying subframes in a radio frame on which a UE may receive a Physical Downlink Control Channel (PDCCH) or enhanced PDCCH (ePDCCH) transmission. Specifically, the UE may receive multiple indications of uplink/downlink (UL/DL) subframe configurations and identify one or more subframes in which the UE may receive the PDCCH or ePDCCH transmission. The UE may then monitor one or more of the identified subframes and base discontinuous reception (DRX) timer functionality on one or more of the identified subframes.
Claims17
One or more non-transitory computer-readable media comprising instructions that, when executed by one or more processors, are to:
- identify, based on an indication of a downlink-reference (DL-reference) uplink/downlink (UL/DL) subframe configuration received via one or more radio resource control (RRC) signals, a value of k subframes associated with an interval between a DL transmission and a UL hybrid automatic repeat request (HARQ) feedback related to the DL transmission in accordance with the DL-reference UL/DL configuration;
- identify a HARQ round-trip time (RTT) of k+4 subframes based on the value of k subframes;
- and
- perform a HARQ process related to the HARQ RTT of k+4 subframes.
An apparatus comprising:
- means to receive an indication of a downlink-reference (DL-reference) uplink/downlink (UL/DL) subframe configuration via one or more radio resource control (RRC) signals;
- means to identify, based on the indication, a value of k subframes associated with an interval between a DL transmission and a UL hybrid automatic repeat request (HARQ) feedback related to the DL transmission in accordance with the DL-reference UL/DL configuration;
- means to identify a HARQ round-trip time (RTT) of k+4 subframes based on the value of k subframes;
- and
- means to perform a HARQ process related to the HARQ RTT of k+4 subframes.
A user equipment (UE) comprising:
- a processor to:
- identify, based on an indication of a downlink-reference (DL-reference) uplink/downlink (UL/DL) subframe configuration received via one or more radio resource control (RRC) signals, a first subframe associated with a DL transmission and a second subframe associated with a UL hybrid automatic repeat request (HARQ) feedback related to the DL transmission in accordance with the DL-reference UL/DL configuration;
- identify, based on an interval between the first subframe and the second subframe, a value of k subframes;
- and
- activate a timer related to a value of k+4 subframes;
- and
- transceiver circuitry coupled with the processor, the transceiver circuitry to:
- receive the DL transmission and the indication of the DL-reference UL/DL subframe configuration;
- and
- transmit the UL HARQ feedback.
An apparatus comprising:
- one or more processors;
- and
- one or more non-transitory computer-readable media comprising instructions, that when executed by the one or more processors, cause the one or more processors to:
- identify, based on an indication of a downlink-reference (DL-reference) uplink/downlink (UL/DL) subframe configuration received via one or more radio resource control (RRC) signals, a value of k subframes associated with an interval between a DL transmission and a UL hybrid automatic repeat request (HARQ) feedback related to the DL transmission in accordance with the DL-reference UL/DL configuration;
- identify a HARQ round-trip time (RTT) of k+4 subframes based on the value of k subframes;
- and
- perform a timer related to the HARQ RTT of k+4 subframes.
