摘要： Systems and methods for selecting Physical Uplink Control Channel (PUCCH) resources are disclosed. An Enhanced Physical Downlink Control Channel (EPDCCH) is detected in signals received from a base station in a first subframe. A HARQ-ACK resource indicator offset (ΔARO) value is identified for the EPDCCH. A PUCCH resource is selected for transmission of a Hybrid Automatic Repeat reQuest-ACKnowledgement (HARQ-ACK) corresponding to the EPDCCH. The PUCCH resource is selected based upon the ΔARO value. The ΔARO value may correspond to a semi-statically configured PUCCH resource. A second PUCCH resource may be selected for transmission of the HARQ-ACK on a second antenna port. A HARQ-ACK resource offset field value may be detected in a Downlink Control Information (DCI) format of the EPDCCH. A table that maps the HARQ-ACK resource offset field value for certain DCI formats to ΔARO values may be used to determine the ΔARO value for the EPDCCH.

摘要： A wireless transmission system included at least one user equipment and a base station. The base station is operable to form a downlink control information block, modulate the downlink control information, precode the modulated downlink control information, and transmit the precoded, modulated downlink control information on at least one demodulation reference signal antenna port to the at least one user equipment. The precoded, modulated downlink control information is mapped to a set of N1 physical resource block pairs in a subframe from an orthogonal frequency division multiplexing symbol T1 to and orthogonal frequency division multiplexing symbol T2.

摘要： Carrier aggregation allows concurrent transmission on multiple component carriers (CC) to increase the data rate. A user equipment (UE) device in a cellular network provides periodic or aperiodic channel state information of the DL channel to a base station (eNB) for each of the aggregated CCs. The UE receives two or more reference signals corresponding to two or more aggregated CCs from an eNB. The UE computes a plurality of channel state information (CSI) reports for each of two or more aggregated CCs derived from the two or more reference signals. The UE receives a positive CSI request from the eNB for a CSI report and transmits CSI feedback to the eNB comprising one or more CSI reports selected from the plurality of CSI reports.

摘要： An apparatus for use in a wireless communication network, comprising a processing resource configured to determine a time interval for periodic time division duplex (TDD) Uplink/Downlink (UL/DL) reconfiguration windows, generate a UL/DL reconfiguration command to indicate a dynamic TDD UL/DL allocation change, and encode the UL/DL reconfiguration command in a physical downlink control channel (PDCCH) data, and a radio front end (RF) interface coupled to the processing resource and configured to cause the encoded UL/DL reconfiguration command to be transmitted to a first of a plurality of wireless user equipment (UEs) in a first of the UL/DL reconfiguration windows, wherein the encoded UL/DL reconfiguration command is transmitted via a PDCCH to provide a fast TDD UL/DL reconfiguration.

摘要： Embodiments of the invention use signaling mechanisms that enable dynamic reconfiguration of the UL/DL resource partitioning by user equipment (UE) in a TDD wireless communication system, such as the 3GPP TDD Long Term Evolution (TD-LTE) system. The dynamic reconfiguration of the UL/DL resource partitioning disclosed herein may also be applied to any other TDD wireless system employing dynamic reconfiguration of the TDD UL/DL configuration.
