Abstract
Embodiments of the present disclosure include methods, apparatuses, and instructions for receiving at a user equipment (UE) of a third generation partnership project (3GPP) network an offset value selected from a plurality of offset values in downlink control information. The UE also receives one or more enhanced control channel elements (eCCEs) of an enhanced physical downlink control channel (ePDCCH). The UE may then determine an allocation of an uplink resource for a transmission on a physical uplink control channel (PUCCH) based at least in part on the index of a first eCCE and the offset value.
Claims23
An eNodeB (eNB) comprising:
- first circuitry to:
- transmit, on an enhanced physical downlink control channel (ePDCCH), an
- indication of an offset value selected from a plurality of offset values comprising
- offset values of −2, −1, 0, and 2;
- and
- transmit, on the ePDCCH, one or more enhanced control channel elements
- (eCCEs) of the ePDCCH;
- and
- second circuitry to identify a signal on an uplink resource of a physical uplink control channel (PUCCH) that is allocated based at least in part on an index of a first eCCE of the one or more eCCEs and the selected offset value.
One or more non-transitory computer-readable media comprising instructions to, upon execution of the instructions by one or more processors of a user equipment (UE), cause the UE to:
- monitor an enhanced physical downlink control channel (ePDCCH) for an offset value selected from a set comprising −2, −1, 0, and 2;
- obtain one or more enhanced control channel elements (eCCEs) of the ePDCCH;
- and
- determine an allocation of an uplink resource of a physical uplink control channel (PUCCH) based at least in part on an index of a first eCCE of the one or more eCCEs and the offset value.
An eNodeB (eNB) comprising:
- a transmitter to transmit an indication of an offset value of 2, and one or more enhanced control channel elements (eCCEs) of an enhanced physical downlink control channel (ePDCCH);
- a processor coupled with the receiver, the processor to allocate an uplink resource of a physical uplink control channel based at least in part on an index of a first eCCE of the one or more eCCEs and the offset value;
- and
- a receiver coupled with the transmitter, the receiver to receive a signal on a physical uplink control channel (PUCCH) that uses an uplink resource that is allocated based at least in part on an index of a first eCCE of the one or more eCCEs and the offset value.
