Abstract
Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for downlink resource scheduling in wireless networks. In some embodiments, the scheduling may include multi-subframe cross carrier scheduling utilizing downlink control information. Other embodiments may be described and/or claimed.
Claims16
An apparatus comprising:
- scheduling circuitry to:
- receive, from an eNB, downlink control information (DCI) in a first subframe of a primary serving cell (Pcell) of the eNB, the DCI to include a carrier indication field (CIF) value;
- access mapping information, based on the CIF value and a carrier aggregation level;
- and
- determine, based on the mapping information, that the DCI pertains to a second subframe of a secondary serving cell (Scell), wherein the second subframe occurs later in a frame sequence than the first subframe;
- and
- decoder circuitry coupled with the scheduling circuitry to decode a downlink resource of a physical downlink shared channel (PDSCH) transmission in the second subframe of the Scell based on said determination that the DCI pertains to the second subframe,
- wherein:
- the mapping information includes a subframe pairing index that corresponds to a predetermined subframe pairing of subframes 0 and 3 or of subframes 1 and 4;
- and
- the scheduling circuitry is to determine that the DCI pertains to the second subframe based on the subframe pairing index.

An apparatus comprising:
- scheduling circuitry to:
- schedule downlink control information (DCI) in a physical downlink control channel (PDCCH) of a first subframe of a first component carrier of a plurality of component carriers aggregated for communication with a user equipment;
- schedule data for the user equipment in a physical downlink shared channel (PDSCH) of a second subframe of a second component carrier of the plurality of component carriers, wherein the DCI is configured to identify the second subframe of the second component carrier and the second subframe occurs later in a frame sequence than the first subframe;
- and
- access mapping information based on a number of the plurality of component carriers and the second subframe of the second component carrier to identify a CIF value that may be used, along with the number of the plurality of component carriers, to provide an indication that the DCI pertains to the second subframe of the second component carrier;
- and
- encoder circuitry to encode the DCI with the CIF value in the PDCCH and the data in the PDSCH,
- wherein:
- the mapping information includes a subframe pairing index that corresponds to a predetermined subframe pairing of subframes 0 and 3 or of subframes 1 and 4;
- and
- the scheduling circuitry is to identify the CIF value based on the subframe pairing index.

One or more non-transitory, computer-readable media having instructions that, when executed, cause an apparatus to:
- access downlink control information (DCI) received from an eNB in a first subframe of a primary serving cell (Pcell), the DCI to include a carrier indication field (CIF) value;
- access mapping information, based on the CIF value and a carrier aggregation level;
- determine, based on the mapping information, that the DCI pertains to a second subframe of a secondary serving cell (Scell), wherein the second subframe occurs later in a frame sequence than the first subframe;
- and
- decode a downlink resource of a physical downlink shared channel (PDSCH) transmission in the second subframe of the Scell based on said determination that the DCI pertains to the second subframe
- wherein:
- the mapping information includes a subframe pairing index that corresponds to a predetermined subframe pairing of subframes 0 and 3 or of subframes 1 and 4;
- and
- the apparatus is to determine that the DCI pertains to the second subframe based on the subframe pairing index.
