Abstract
Various solutions for multiplexing of short physical downlink control channel and data with respect to user equipment and network apparatus in mobile communications are described. An apparatus may receive a reuse indication from a control channel. The apparatus may determine whether a plurality of control channel elements (CCEs) are reused for a data channel according to the reuse indication. The apparatus may further receive the data channel in the CCEs in an event that the reuse indication indicates that the CCEs are reused.
Claims20
A method, comprising:
- receiving, by a processor of an apparatus, radio resource control (RRC) signaling indicating unused resource elements;
- receiving, by the processor, a usage indication from a control channel;
- determining, by the processor, whether a plurality of control channel elements (CCEs) in control channel search spaces are in use or not in use for a data channel according to the usage indication;
- receiving, by the processor, the data channel;
- and
- performing, by the processor, a data channel rate-matching operation to rate-match around one or more of the CCEs not used for the data channel according to the usage indication and a data channel resource containing a downlink control information (DCI) that schedules the data channel,
- wherein the DCI contains a plurality of bits a value of each indicating whether a corresponding resource or set of resources is used for the data channel, and
- wherein the performing of the data channel rate-matching operation comprises applying indication of the plurality of bits to different CCEs within a given resource according to the unused resource elements indicated in the RRC signaling.

An apparatus, comprising:
- a transceiver capable of wirelessly communicating with a plurality of nodes of a wireless network;
- and
- a processor communicatively coupled to the transceiver, the processor capable of:
- receiving, via the transceiver, radio resource control (RRC) signaling indicating unused resource elements;
- receiving, via the transceiver, a usage indication from a control channel;
- determining whether a plurality of control channel elements (CCEs) in control channel search spaces are in use or not in use for a data channel according to the usage indication;
- receiving, via the transceiver, the data channel;
- and
- performing a data channel rate-matching operation to rate-match around one or more of the CCEs not used for data channel according to the usage indication and a data channel resource containing a downlink control information (DCI) that schedules the data channel,
- wherein the DCI contains predefined bits a value of each indicating whether a corresponding resource or set of resources is used for the data channel, and
- wherein, in performing the data channel rate-matching operation, the processor applies indication of the predefined bits to different CCEs within a given resource according to the unused resource elements indicated in the RRC signaling.
