    摘要: Embodiments of a User Equipment (UE) and methods for packet based device-to-device (D2D) discovery in an LTE network are generally described herein. In some embodiments, UE may be enabled for proximity services and may be configured to receive signaling from an enhanced node B (eNB) indicating resources allocated for D2D discovery. The UE may configure a discovery packet in accordance with a predetermined configuration to have at least a discovery payload and a cyclic-redundancy check (CRC). The discovery payload may include discovery-related content. The UE may be configured to transmit the discovery packet on at least some of the indicated resources for receipt by a receiving UE. In some embodiments, a demodulation reference signal (DMRS) may be selected to indicate a payload size and/or MCS of the discovery packet's payload.

    摘要: 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.

    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: Technology to support mapping for Hybrid Automatic Retransmission re-Quest (HARQ) for Carrier Aggregation (CA) is disclosed. One method can include a user equipment (UE) identifying, within a radio frame, a type 2 DownLink (DL) sub-frame within a virtual bundling window associated with a Secondary Component Carrier (SCC). The type 2 DL sub-frame can be virtually moved from a Primary Component Carrier (PCC) for HARQ-ACKnowledge (HARQ-ACK) multiplexing of the virtual bundling window. The UE can extract a Component Carrier Element (CCE) number for a first CCE used by a Physical Downlink Control CHannel (PDCCH) transmission corresponding to the type 2 DL sub-frame. The UE can determine a Physical Uplink Control CHannel (PUCCH) resource for carrying a HARQ-ACK multiplexing message based on the CCE number when a PCC window size of the PCC is greater than an SCC window size of the SCC.

    摘要: An eNodeB (eNB), user equipment (UE) and method for operating in enhanced coverage (EC) modes are generally described. The UE may receive one or more physical broadcast channel (PBCH) signals, dependent on whether the UE is in a normal coverage mode or in one of the EC modes. The PBCH signal may be combined to form a combined PBCH signal, when the UE is in an EC mode, and decoded to determine one of a plurality of sets of resource regions associated different EC modes for communication with the eNB. The signal may be scrambled using a Radio Network Temporary Identifier (RNTI) dependent on at least one of a signal type of the control signal and the EC mode. Paging and the system information block (SIB) signals in a Physical Downlink Shared Channel (PDSCH) may be decoded without decoding a physical downlink control channel (PDCCH) signal associated with the PDSCH.
