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:
Technology for a user equipment (UE) operable to report periodic channel state information (CSI) to an eNodeB is disclosed. The UE can determine a reporting period (Npd) of a serving cell of the UE. The UE can determine a Time-Division Duplex (TDD) uplink-downlink (UL-DL) configuration of a primary cell of the UE. The UE can encode multiple periodic CSI reports for transmission to the eNodeB using a physical uplink control channel (PUCCH) on the primary cell according to the reporting period Npd.
Abstract:
Technology for a first eNodeB is disclosed. The first eNodeB can decode an uplink-downlink (UL-DL) time-division duplexing (TDD) subframe reconfiguration received from a second eNodeB. The UL-DL TDD subframe reconfiguration can be for the first eNodeB. The first eNodeB can encode the UL-DL TDD subframe reconfiguration received from the second eNodeB for transmission to a plurality of user equipment (UEs).

Abstract:
Mobile communication devices, such as user equipment (UE) using 3GPP-LTE or LTE Advanced, may communicate directly with another UE through a system called Device-to-Device (D2D) communication. The establishment of a D2D communication session may involve having one of the UEs trigger the signaling procedures. In particular, a D2D resource re-allocation method may be used to optimize the D2D communication resource utilization efficiency in a dynamic manner, which is fully controlled by one of the D2D pair (termed the master UE or M-UE). The M-UE may be arranged to re-allocate resources based on the buffer status report (BSR) of the UEs in the D2D communication session. The M-UE may be further arranged to dynamically change the configuration of the transmission window based on characteristics of the D2D communication session.

Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for transmitting periodic channel state information having large payload sizes. Other embodiments may be described and claimed.
Abstract:
Technology for adapting uplink-downlink (UL-DL) time-division duplexing (TDD) subframe configurations in a heterogeneous network (HetNet) is disclosed. One method can include a reference enhanced Node B (eNB) determining a preferred adaptive UL-DL configuration. The eNB can receive node configuration information for at least one neighboring node. The eNB can reconfigure an adaptive UL-DL configuration for at least one of the reference eNB and the at least one neighboring node based on the node configuration information and sounding reference signal (SRS) subframe scheduling of the reference eNB and the at least one neighboring eNB.
Abstract:
An apparatus and method to facilitate provision of acknowledgement signals in a wireless communications network are disclosed herein. An evolved node B (eNodeB) transmits radio resource control (RRC) signals indicating inclusion of an enhanced physical hybrid automatic repeat request (ARQ) indicator channel (e-PHICH) in a radio frame. The eNodeB configures the radio frame including the e-PHICH. At least one subframe of the radio frame includes a first resource block (RB) associated with a first UE, a second RB associated with a second UE, and a third RB. The first RB includes a physical downlink control channel (PDCCH) control region in a Slot 0 of the subframe and a first enhanced PDCCH (e-PDCCH) allocation in the Slot 0 and in a Slot 1 of the subframe. The e-PHICH allocation is included in the third RB or at least the Slot 1 of the subframe of the first RB.
Abstract:
An enhanced physical down link control channel (ePDCCH) for Long Term Evolution (LTE) systems is described that is constructed using enhanced control channel elements (eCCEs). Techniques are also described by which user equipment (UE) may be implicitly allocated uplink resources for transmitting acknowledgements to data received via downlink resources allocated by an ePDCCH.
Abstract:
Examples are disclosed for timers associated with powering receiver circuitry at a wireless device or user equipment. The examples include separately defining one or more timers based on different time division duplex (TDD) configurations. The different TDD configurations may be used for communications between user equipment and serving cells supported by one or more base stations such as evolved node Bs (eNBs) in a Long Term Evolution (LTE) wireless network. The defined timers may be used by the user equipment to selectively power receiver circuitry. Other examples are described and claimed.
