摘要:
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.

摘要:
A user equipment (UE) enables synchronous peer-to-peer communication between devices for out of network coverage and partial network coverage scenarios. The UE performs a synchronization procedure and selects a spectrum resource within an uplink (UL) spectrum for device-to-device (D2D) communication. The UE, representing a synchronization source, generates timing information and synchronization signals for synchronizing a group of wireless communication devices (peer UEs) with the UE in a local synchronization area. The UE transmits, in selected or pre-allocated time or frequency resources, a synchronization signal including the timing information in order to synchronize devices in the local synchronization area.

Technology for a user equipment (UE) to communicate in a device to device (D2D) network is described. A temporary identification (Temp ID) can be received from an enhanced node B (eNB). A D2D discovery resource allocation can be received within a physical uplink channel from the eNB. A UE D2D discovery resource can be selected from the D2D discovery resource allocation based on the Temp ID. A D2D discovery beacon can be transmitted from the UE D2D discovery resource to enable other UEs to detect the UE.

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.

Embodiments of a UE to operate in accordance with a device-to-device (D2D) communication mode are disclosed herein. The UE may include hardware processing circuitry to determine a synchronization reference time based on reception of signals from an eNB. The hardware processing circuitry may be further to, during a D2D communication session, transmit Multi-Time Transmission Interval Bundle Groups (MTBG) of data symbols during a first group of Data Transmission Intervals (DTI) and refrain from transmission of data symbols during a second group of DTIs. Starting times of the DTIs may be based at least partly on the synchronization reference time. The hardware processing circuitry may be further to transmit, during an in-network communication session, data symbols according to a Time Transmission Interval (TTI) reference time synchronized to the synchronization reference time.

Embodiments of an enhanced node B (eNB), user equipment (UE) and methods of signaling for proximity services and device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments, the eNB may transmit signaling to indicate D2D discovery zone configuration to proximity service (ProSe) enabled UEs. The signaling may indicate time and frequency resources and a periodicity of a discovery zone and may indicate operational parameters for the discovery zone. The resources of the D2D discovery zone may be allocated for D2D discovery signal transmission by the ProSe-enabled UEs.
摘要:
An evolved Node-B (eNB), user equipment (UE) and method for handling overlapping resource pools for device-to-device (D2D) transmission are generally described. Resources for D2D communication with at least one other UE may be requested by the UE. The allocated pools may overlap. The overlapping pools may comprise pools of the same type or different types. The types of pools may include a discovery pool, a Scheduling Assignment (SA) pool and a Mode-2 data pool. The eNB may resolve conflict among the pools by transmitting an indication of allocation of only one of the pools or may permit the UE to determine which pool to use for transmission. The pool may be selected based on at least one of usage index, configuration identity, and usage priority. The usage index may include traffic types, mode switching, L2 control, UE classification, data rate, real-time/non-real time, latency, and Quality of Service (QoS).

摘要:
A user equipment (UE) is capable of directly communicating with one or more other UEs using a 3rd Generation Partnership Project (3GPP) communication specification. The UE is configured to identify a gap size for a device-to-device communication. The UE is configured to identify a cyclic prefix length for the device-to-device communication and transmit the device-to-device communication comprising a subframe having a physical uplink shared channel (PUSCH) structure. The subframe has the identified cyclic prefix length, and one or more last symbols of the subframe include a gap having the identified gap size.
