    摘要: A method communicates symbols in a cell of a multiple-input multiple-output (MIMO) network that includes a set of mobile station and a base station. The symbols are communicated using orthogonal frequency division multiplexing (OFDM) and time division duplex (TDM). A frame for communicating the symbols between the base station and the mobile station is constructed. The frame is partitioned into a downlink subframe and an uplink subframe. The uplink subframe is partitioned into a first zone and a second zone, wherein the first zone uses orthogonal frequency division multiple access (OFDMA) and the second zone uses single carrier frequency division multiple access (SC-FDMA).

    摘要: An orthogonal frequency division multiple access (OFDMA) network including a base station (BS) associated with a set of mobile stations (MS) in a cell. The set of MS are grouped into sets of active MS, wherein each set of active MS corresponds to a beam formed at the BS. The BS transmits a down link (DL) subframe using analog beam forming (ABF), wherein the DL subframe has one ABF zone for each set of active MS and each corresponding beam.

    摘要: A method for selects antennas in a spatial division multiple access (SDMA) wireless network that includes a base station and a set of mobile stations, in which the set of mobile stations includes one or more designated mobile stations, and in which each designated mobile station has a set of multiple antennas. Channel state information (CSI) is acquired for a channel between each mobile station in the set of mobile stations and the base station, and in which the CSI for each designated mobile station is acquired for different subsets of the set of multiple antennas at each designated mobile station. For each designated mobile station, a globally optimal subset of the set of antennas is selected based on the CSI acquired from all the mobile stations.

    摘要: A method transmits a block of symbols in a multiple-input multiple-output (MIMO) network including a transmitter having a set of transmit antennas and a receiver having a set of receive antennas. A block of symbols is coded with a first code to generate a first block, which is transmitted and received. If a decoding of the first block is incorrect, then block of symbols is coded with the first code and then a second code different than the first code to generate a second block. The second block is transmitted, received and combined with the first block to recover the block of symbols.

    摘要: In a wireless network including a base station (BS) and a set of mobile stations (MS), a MS transmits a ranging request message to the BS, using random access, when the MS enters the cell. The ranging request message includes request MS specific information for identifying the MS. The MS receives a ranging response message broadcast from the BS, which includes response MS specific information, request and response specific information to determine whether the BS received the request, or whether a collision occurred.
