Abstract:
An apparatus and method for managing interference to facilitate allocation of a dynamic uplink and downlink configuration are disclosed herein. Determining whether a first cell causes interference less than a pre-determined threshold level to one or more neighboring cells or whether flexible subframes of radio frames associated with the one or more neighboring cells operate as downlink subframes. In response to the determining condition being met, allocating a first flexible subframe of a first radio frame associated with the first cell to operate as a downlink subframe at normal transmit power level. In response to the determining condition not being met, allocating the first flexible subframe of the first radio frame associated with the first cell as one of a downlink subframe operating in a reduced transmit power level or as an uplink subframe.

Abstract:
Embodiments of a system and method for reporting channel state information (CSI) in a wireless network are generally described herein. In some embodiments, an apparatus of a User Equipment (UE) can include physical layer circuitry to receive, in a first subframe, a first aperiodic CSI request from a first cell group, and a second aperiodic CSI request from a second cell group. The UE can include processing circuitry to determine a number of requested CSI processes corresponding to the first aperiodic CSI request and the second aperiodic CSI request. Additionally, the processing circuitry can select a subset of the requested CSI processes when the determined number of requested CSI processes is more than five. Furthermore, the processing circuitry can calculate CSI for the selected CSI processes.

Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for multiplexing channel state information and hybrid automatic repeat request-acknowledgement information. Other embodiments may be described and claimed.
Abstract:
Disclosed is a method of transmitting, from an enhanced Node B (eNB), an indication of an uplink/downlink (UL-DL) subframe configuration of a scheduling cell and a scheduled cell in a wireless time-division duplex (TDD) system. Embodiments include identifying the type of the UL-DL subframe configuration of the scheduling cell and determining a UL-DL subframe configuration to use for UL resource allocation of the scheduled cell. Other embodiments include identifying a reference UL-DL subframe configuration to use for UL resource allocation of the scheduled cell.
Abstract:
Technology for reducing coexistence interference in a multi-radio device is disclosed. One method comprises applying discontinuous reception (DRX) to a user equipment (UE) having a plurality of radio transceivers. The DRX can include a long DRX cycle for the UE. One of a 2 milliseconds (ms), 5 ms, and 8 ms cycle start offset period may be provided for the long DRX cycle to reduce coexistence interference between the plurality of radio transceivers in the UE. The cycle start offset period is selected to provide at least one Hybrid Automatic Repeat Request (HARQ) process reservation pattern to reduce the coexistence interference between the plurality of radio transceivers in the UE.
Abstract:
An apparatus is provided for a device-to-device, D2D, communication enabled user equipment, UE, comprising a processing section to determine, based on a signal received from another UE, a channel condition between the UE and the another UE; the UE to report the determined channel condition to an evolved Node B, eNB. The processing section is to initiate D2D communication based on a communication from the eNB, received in response to the report. Also, an apparatus is provided for a network element, comprising An input to receive a describing a channel condition between a first UE and a second UE; a processor to determine, based on the channel condition, whether or not D2D communication between the first UE and the second UE is to be enabled; and an output to output a result of the determination when the processor determines D2D communication is to be enabled. Related methods are also provided.

Abstract:
Disclosed is a method including communicating, by a mobile device, with a base station via first and second component carriers having different frequency bands and time division duplexing (TDD) configurations. The method may include receiving one or more downlink transmissions via the second component carrier. The method may include selecting a hybrid automatic repeat request (HARQ) timing sequence based on the TDD configurations of the first and second component carriers. The method may include transmitting one or more positive acknowledgment and/or negative acknowledgement (ACK/NACK) signals, associated with the one or more downlink transmissions, according to the selected HARQ timing sequence. Other embodiments may be described and claimed.
Abstract:
Embodiments of a central processing unit and methods for supporting coordinated multi-point (CoMP) transmissions in a 3GPP LTE network with non-ideal backhaul links are generally described herein. In some embodiments, the CPU may be arranged for scheduling and assigning resources for subordinate enhanced node Bs (eNBs) over the backhaul links for CoMP transmissions. The scheduling may include an additional number of HARQ processes to compensate, at least in part, for backhaul link latency.
