摘要： Systems and methods are disclosed that relate to management of uplink (UL) transmissions in unlicensed spectrum. In some embodiments, a method of operation of a network node in a wireless communication network comprises signaling, to a wireless device, an indication of one or more allocated sets of Resource Blocks (RBs) that are allocated to the wireless device by a UL grant for transmission on a UL carrier in an unlicensed frequency spectrum. The one or more allocated sets of RBs are one or more of a plurality of defined sets of RBs that correspond to a plurality of interlaces, respectively, that each spread out across an entire bandwidth of the UL carrier. In this manner, higher UL user and system performance can be obtained.

摘要： According to some embodiments, a method for use in a wireless device of acquiring system information in a frequency-hopping network comprises obtaining an indication that the wireless device is configured for frequency hopping among a plurality of frequency channels. At least one of the plurality of frequency channels is a discovery channel. The discovery channel includes one or more dense discovery signals. A dense discovery signal is denser than a corresponding discovery signal included in the non-discovery channels of the plurality of frequency channels. The method further comprises tuning a radio receiver of the wireless device to the discovery channel, and acquiring system information using the one or more dense discovery signals. For example, a discovery signal (e.g. NPSS, NSSS, NPBCH, etc.) of the non-discovery channel may include one occurrence per frame and the corresponding discovery signal of the discovery channel includes more than one occurrence per frame.

摘要： According to some embodiments, a method for use in a frequency-hopping wireless transmitter for transmitting in unlicensed spectrum comprises: obtaining a configuration for a plurality of frequency channels in unlicensed spectrum; and transmitting a data transmission according to a frequency-hopping pattern across the plurality of frequency channels. The configuration for the plurality of frequency channels comprises a first subset of frequency channels for downlink transmission and a second subset of frequency channels for uplink transmission. The frequency channels in the first and second subsets are mutually exclusive. In some embodiments the first and second subset of frequency channels each comprise 160 frequency channels in the 2.4 GHz band, or 50 frequency channels in the 915 MHz band.

摘要： A method for operating a radio node (10) for a wireless communication network is described. The radio node (10) is adapted for performing a Listen-Before-Talk, LBT, procedure to determine whether accessing at least one carrier for transmission of data is allowed. The method comprises adjusting the LBT procedure based on operating conditions, wherein adjusting the LBT procedure includes changing a contention window size and/or a random backoff number of the LBT procedure; and/or changing scheduling of data for the at least one carrier; and/or changing a defer period or arbitration interframe spaces.

摘要： Systems and methods are described herein relating to preemptive retransmission of a transport block in successive subframes on, e.g., a Listen-Before-Talk (LBT) cell. Embodiments of a method of operation of a radio node of a cellular communications network are disclosed. The radio node serves an LBT cell. In some embodiments, the method of operation of the radio node comprises transmitting a transport block in a first subframe on the LBT cell and retransmitting the transport block in a second subframe (e.g., on the LBT cell), where the second subframe is adjacent, in time, to the first subframe. In embodiments in which the retransmission of the transport block is on the LBT cell (or another LBT cell), the time span of a transmission burst can be extended to a maximum allowed burst duration.

摘要： Systems and methods relating to Listen before Talk (LBT) procedures suitable for, e.g., License Assisted Access (LAA) to an unlicensed frequency spectrum or Long Term Evolution Unlicensed (LTE-U) are disclosed. In some embodiments, a method of operation of a node of a cellular communications network comprises performing a LBT procedure for an observed channel in an unlicensed frequency spectrum. The LBT procedure defers at least one Clear Channel Assessment (CCA) slot such that the LBT procedure concludes at or near a desired starting point for a transmission. The at least one CCA slot comprises at least one of a first CCA slot of the LBT procedure, one or more intermediate CCA slots of the LBT procedure, and a final CCA slot of the LBT procedure. The method further comprises performing the transmission on the observed channel upon completion of the LBT procedure.
