    摘要: A system and method includes implementing, by a base station (BS), a reliable ultra-low latency transmission mechanism in a grant-free uplink transmission scheme having defined therein contention transmission unit (CTU) access regions and a plurality of CTUs. Implementing the reliable ultra-low latency transmission mechanism includes defining a reliable ultra-low latency CTU (RULL-CTU) access region from a portion of the CTU access regions of the grant-free transmission scheme, defining an RULL-CTU mapping scheme by mapping at least a portion of plurality of CTUs to the RULL-CTU access region to define a plurality of RULL-CTUs, defining a reliable ultra-low latency user equipment (RULL-UE) mapping scheme by defining rules for mapping a plurality of RULL-UEs to the plurality of RULL-CTUs in an initial pattern for initial transmissions in a first transmission time interval (TTI), and a regrouped pattern for redundant transmissions in a second TTI subsequent to the first TTI.

    摘要: In a method of providing downlink retransmissions to a mobile station in a wireless communication network, the wireless communication network comprising a base station communicatively linked to a transparent relay station, the base station receives a request for a retransmission from the mobile station; schedules resources for the retransmission; signals scheduling information for the retransmission to the transparent relay station via a control link; and the transparent relay station receives the scheduling information for the retransmission on the control link; and sends the retransmission to the mobile station in a retransmit subframe on a retransmit frequency band.

    摘要: Methods, devices and systems for encoding and transmitting data in a wireless communications system and, in particular, for unscheduled data transmissions including low data rate transmissions. The method for transmitting data in a wireless network includes mapping data according to a predefined sequence pattern from a group of sequence patterns to provide a spreading sequence that includes multiple non-zero elements and that is enabled to partially collide in the wireless network with other spreading sequences that have been mapped according to other sequence patterns from the group; and transmitting the spreading sequence. Multiple sequences may be received by a network node and decoded using successive interference cancellation (SIC) techniques.

    摘要: An apparatus and method for transmitting data with conditional zero padding is provided. In accordance with an embodiment of the disclosure, a transmitter transmits data to a receiver by transmitting symbols such that each symbol is preceded by a cyclic prefix of a fixed length and the symbol conditionally includes enough zero padding to avoid ISI (Inter-Symbol Interference) between consecutive symbols. In some implementations, if the fixed length for cyclic prefixes is long enough to avoid ISI between consecutive symbols, then the symbols may omit zero padding. Otherwise, the symbols may include enough zero padding to avoid ISI between consecutive symbols. The zero padding may be zero tail or zero head.

    摘要: A method for reducing interference at a first user equipment (UE) includes receiving, by a second communications controller, a request to reduce interference at the first UE, the first UE being served by a first communications controller. The method also includes determining, by the second communications controller, a beam adjustment in accordance with uplink transmission measurements of the first UE and a second UE, the beam adjustment to aim a transmission to the second UE away from the second UE and towards an angle orthogonal to a first direction of the first UE relative to the second communications controller, the second UE being served by the second communications controller. The method further includes pre-adjusting, by the second communications controller, the transmission with the beam adjustment, and transmitting, by the second communications controller, the pre-adjusted transmission to the second UE.
