摘要: Methods and systems are disclosed for symbol sequence generation and transmission for non-orthogonal multiple access (NoMA) transmission. A NoMA signal may be generated based on: (1) a first symbol sequence, the first symbol sequence determined from a set of input bits and associated with a first MA signature within a first MA signature space; (2) a second symbol sequence determined based on the first symbol sequence, the second symbol sequence being associated with a second MA signature within a second MA signature space; and (3) a symbol-to-resource element mapping applied to the second symbol sequence to produce the NoMA signal.

摘要: Aspects of the present disclosure provide a scheme for generating a multiple access (MA) signal that include mapping each of at least one stream of bits to generate a set of modulated symbols and transmitting the set of modulated symbols. The spreading signatures that are selected to map the at least one stream of bits are selected, at least in part, based on a set of compatibility rules. The spreading involves mapping each stream of bits using a respective spreading signature from a set of spreading signatures to generate a respective set of modulated symbols, wherein real spreading signature components of the spreading signatures are orthogonal to each other and imaginary spreading signature components of the spreading signatures are orthogonal to each other.

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: The present invention provides a solution to improve coverage and cell edge performance in a mobile user communication system is the use of fixed relays, which are pieces of infrastructure without a wired backhaul connection. The relays transmit or “relay” downlink messages between the base station (BS) and mobile stations (MSs) through a multi-hop communication. The present invention is a method and system for supporting a multiple user mobile broadband communication network that includes relay techniques suitable for user equipment in the downlink communication to the user equipment.

摘要: Systems and methods are disclosed herein for an enhanced Multimedia Broadcast Multicast Service (MBMS) in a wireless communications network. In one embodiment, a number of base stations in a MBMS zone, or broadcast region, accommodate both Spatial Multiplexing (SM) enabled user elements and non-SM enabled user elements. In another embodiment, a number of base stations form a MBMS zone, or broadcast region, where the MBMS zone is sub-divided into an SM zone and a non-SM zone. In another embodiment, the wireless communications network includes multiple MBMS zones. For each MBMS zone, base stations serving the MBMS zone transmit an MBMS zone identifier (ID) for the MBMS zone. The MBMS zone ID may be used by a user element for decoding and/or to determine when to perform a handoff from one MBMS zone to another.

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: 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.

摘要: A method and apparatus are provided for a wireless communication system including a base station and at least one user equipment. A Channel Quality Indicator (CQI) table can be generated so that only an index corresponding to the measured CQI needs to be fed back to the base station. The CQI tables proposed herein may be suitable to different channel statistics, different Multiple Input Multiple Output (MIMO) mode and may be optimized based on either performance or implementation complexity. Multiple CQI tables may be formed into one compound CQI table. The CQI tables may be stored at both a base station and user equipment. The base station can select a CQI table from the set of tables. The base station signals the selection of the CQI table to the user equipment and the user equipment feeds back indices from the selected CQI table to the base station.
