摘要： Radio frame configuration circuitry for use in a device of a wireless communication system is provided. The radio frame configuration circuitry uses control circuitry to select between a plurality of different time-division duplex, TDD, configurations for a radio frame having slots with a configured duration. Transceiver circuitry performs TDD communications based on selections made by the control circuitry such that an average periodicity of switching between transmission of information and reception of information during the TDD communication is the same despite switching between different ones of the plurality of different TDD configurations. The radio frame configuration circuitry can be incorporated in a UE or an eNodeB or a Peer Radio Head. A corresponding method is provided.

摘要： Disclosed in some examples are systems, machine-readable media, methods, and cellular wireless devices which implement a Listen-Before-Talk (LBT) access scheme for a device operating according to a cellular wireless protocol in an unlicensed channel. A cellular wireless device may utilize the cellular wireless protocol in the unlicensed channel after the LBT access scheme has determined that a channel (a defined range of frequencies) in the unlicensed channel is idle for a particular period of time.

摘要： Systems, apparatus, user equipment (UE), evolved node B (eNB), computer readable media, and methods are described for multi-carrier listen before talk operations. In various embodiments, a transmitting device may assign one or more primary carriers to perform listen before talk (LBT) operations, with non-primary carriers performing a channel sensing operation at the end of the LBT operations of at least one primary channel. In various embodiments, the LBT operations at the primary carriers may use a shared random countdown number or an independent random countdown.

摘要： Embodiments of an Evolved Node-B (eNB) and methods for HARQ transmission are disclosed herein. The eNB may transmit, to a reduced-latency User Equipment (UE), an initial HARQ block and a diversity HARQ block for a reduced-latency data block. A sub-frame spacing between the transmissions of the HARQ blocks may be less than a sub-frame spacing used for transmissions of HARQ blocks to UEs not operating as reduced-latency UEs. The HARQ blocks for the reduced-latency data block may be transmitted in a reduced-latency region of time and frequency resources reserved for HARQ processes with reduced-latency UEs. In addition, HARQ blocks may be transmitted in time and frequency resources exclusive of the reduced-latency region to other UEs not operating as reduced-latency UEs.

摘要： A user equipment (UE) can reserve shared spectrum between two wireless protocols upon the request from a tower. For example, an enhanced node B (eNB or eNodeB) transmits a message to associated UEs including a set of candidate UEs, a length of time to reserve, and a frequency band to use. UEs perform medium sensing on the specified spectrum if a UE finds its identifier in the set of candidate UEs. Candidate UEs transmit a clear to send (CTS) message with channel reservation information if the medium is idle. A result of the success or failure of the CTS transmission attempt is sent back to the eNB. Upon receiving the feedback information from the UEs, the eNB starts sending data to those UEs that sent the positive feedback on the channel reservation.
