Abstract: Briefly, in accordance with one or more embodiments, a base transceiver station having a first set of antennas and a second set of antennas geographically separated from the first set of antennas transmits a reference signal to a first device, and receives feedback from the first device. The feedback represents information that can be used to construct a weight adjustment vector. The base transceiver station selects a precoding vector from a codebook based at least in part on the feedback received from the first device, calculates the weight adjustment vector based at least in part on the feedback, and applies the weight adjustment vector to the selected precoding vector to provide an adjusted precoding vector. The base transceiver station then may transmit data to the first device using the adjusted precoding vector.

Abstract: Technology for a user equipment (UE) configured for blind decoding downlink control information (DCI) from an enhanced physical downlink control channel (EPDCCH). The UE can receive, from a base station, the EPDCCH that includes the DCI. The UE can attempt one or more times to decode the DCI from enhanced control channel elements (ECCE) of the EPDCCH from physical resource block (PRB) region candidates in a PRB set using a selected set of enhanced resource element group (EREG) index maps for the ECCE until the DCI is successfully decoded. The resource elements (REs) of a PRB pair can include a block of symbols mapped in sequence to resource elements on an associated port when the REs are part of the EREGs assigned for the EPDCCH transmission.

Abstract: Technology to provide physical uplink control channel (PUCCH) resource allocation in time division duplex (TDD) for a hybrid automatic retransmission request-acknowledge (HARQ-ACK) transmission in a subframe n is disclosed. In an example, a user equipment (UE) can include first circuitry configured to detect a downlink control channel within a prior specified subframe that is received in time before the subframe n. The UE can include second circuitry configured to: determine that the downlink control channel detected within the prior specified subframe is one of a physical downlink control channel (PDCCH) or an enhanced physical downlink control channel (EPDCCH); and determine one of a legacy PUCCH resource for the HARQ-ACK transmission when the downlink control channel detected within the prior specified subframe is the PDCCH or an enhanced PUCCH resource for the HARQ-ACK transmission when the downlink control channel detected within the prior specified subframe is the EPDCCH.
