摘要： A next generation vehicle-to-everything (NGV) station (STA) operating as an initiating station (ISTA) for performing non-trigger-based NGV ranging may encode an NGV ranging null-data packet (NDP) announcement (NGV NDPA) frame for transmission to a responding station (RSTA) to initiate the non-trigger-based NGV ranging. The NGV STA may also encode an initiator-to-responder (I2R) NGV ranging null-data packet (NDP) (I2R NGV ranging NDP) for transmission following the NGV NDPA frame. The I2R NGV ranging NDP may be encoded in accordance with a NGV Ranging NDP format that may include an NGV signal field (NGV-SIG), a repeated NGV-SIG (RNGV-SIG), an NGV Short Training field (NGV-STF) and an NGV long training field (NGV-LTF). The NGV-LTF may include one or two sets of LTF symbols depending on a number of LTF symbol repetitions (LTF_REP). Each set of LTF symbols may have one or two LTF symbols depending on a number of spatial streams (NUM_SS) and the NGV-LTF may be encoded without a packet extension (PE).

摘要： This disclosure describes systems, and methods related to determining carrier frequency offset of a wireless communication channel based on a determined phase difference. In some embodiments, an access point is caused to receive one or more streams comprising one or more encoded long training field (LTF) symbols over the wireless communication channel from one or more user devices. The access point then determines a first phase of the wireless communication channel upon receipt of a first LTF symbol, and determines a second phase of the wireless communication channel upon receipt of a second LTF symbol. The access point next determines a phase difference between the first phase and the second phase. Based on the determined phase difference, the access point determines a carrier frequency offset of the wireless communication channel. Lastly, the access point modifies the wireless communication channel based at least in part on the determined CFO.

摘要： A system and method for distributed scheduling of transmissions between device-to-device (D2D) communications is disclosed. The distributed scheduling method employs a distributed scheduling structure in which device identifiers rather than connection identifiers are used to enable scheduling of a D2D data transfer between devices in a wireless neighborhood. The novel distributed scheduling structure is scalable to a larger number of D2D devices than is feasible with a connection ID-based tone matrix.

摘要： Technology for performing indexing on localized enhanced control channel elements (eCCEs) and distributed eCCEs for ePDCCH in a radio frame is disclosed. One method comprises indexing localized eCCEs and distributed eCCEs independently based an aggregation level for an enhanced physical downlink control channel (ePDCCH) transmission. For example, physical indexes of the localized eCCEs may be indexed in frequency increasing order while the indexing is aggregation level specifically mapped to physical indexes. For distributed eCCEs, the logical indexing may further take inter-cell interference (ICIC) coordinate region into consideration. The eCCE indexes belonging to the search space for a given aggregation level (AGGL) may distribute across different ICIC coordinate regions. Further, an AGGL specific global logical indexing may be applied to localized eCCEs and distributed eCCEs with the logical indexes for localized eCCEs and distributed eCCEs interleaved with each other. The ICIC region may also be considered in the global indexing. The AGGL specific eCCE indexing can be used for ePDCCH assignment and blind decoding and/or resource allocation for ePDCCH. The physical eCCE indexes can be used for implicit index derivation for a physical uplink control channel (PUCCH).
