    摘要： Devices, methods, user equipment (UE), evolved node B (eNB), and storage media are described suitable for coexistence operations for uplink communications on multiple unlicensed carriers. Various embodiments are implemented in LTE systems with license-assisted access (LAA) associated communications. In one embodiment, a UE processes one or more uplink grants from an eNB scheduling transmissions on multiple unlicensed carriers at a first time, and indicating a first channel access procedure. The UE then selects a first unlicensed carrier and performs the first channel access procedure, and performs a second channel access procedure on a second unlicensed carrier of the multiple unlicensed carriers.

    摘要： Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for scheduling of multiple uplink transmissions in unlicensed spectrum. One embodiment involves receiving, at an eNB, a first uplink scheduling request from a UE, scheduling a plurality of uplink subframes on the unlicensed channel in response to the first uplink scheduling request, and initiating transmission of a first subframe to the first UE in response to the scheduling of the plurality of uplink subframes, wherein the first subframe comprises one or more downlink control indicators (DCIs) allocating the plurality of uplink subframes to the first UE.

    摘要： Techniques for transmission of a physical downlink control channel (PDCCH) or enhanced PDCCH (EPDCCH) within a partial subframe of a license assisted access (LAA) burst are discussed. One example apparatus comprises a processor configured to generate a LAA burst; generate one or more downlink control channel messages that comprise at least one of PDCCH messages or EPDCCH messages; generate a physical layer encoding of the LAA burst comprising a first partial subframe, wherein the first partial subframe comprises a physical layer encoding of the one or more downlink control channel messages; and output the first partial subframe comprising the physical layer encoding of the one or more control channel messages to transmitter circuitry for subsequent transmission via an unlicensed carrier.
