Methods and systems for allocating HARQ resources in the PUCCH with TDD for the enhanced physical downlink control (EPDCCH) channel

摘要

Method (1800) applied in a wireless device (12) operating in a 3GPP LTE wireless communication network (50) configured for time division duplexing operation, TDD, said method comprising receiving (1810) information from DCI downlink control through an enhanced physical downlink control channel ePDCCH, in a downlink subframe, planning the received ePDCCH a transmission in the downlink shared channel to the wireless device (12), or indicating a release of the semi-persistent SPS planning towards the wireless device, in which the method further comprises: determining (1820) a resource index for a physical uplink control channel resource, PUCCH, based on the lower index of improved control element , eCCE, of the received DCI, at a specific offset value for the device previously signaled to the device wireless vo by radio resource control signaling, RRC, and on an index i, in which index i identifies the downlink subframe in a predetermined set of multiple downlink subframes associated with an uplink subframe, in that said determination is in accordance with a sequential allocation of PUCCH resources in the uplink subframe in relation to the downlink subframes associated with the uplink subframe associated with the uplink subframe, for each of a plurality of resource sets in the ePDCCH in which the DCI has been detected; and transmitting (1830) a hybrid automatic repeat feedback, HARQ, in the uplink subframe, using a PUCCH resource corresponding to the determined resource index.
