摘要： A wireless communication system (100) is provided that spreads pilot signals, or channel state information reference signals (CSI-RSs), using a spreading code chosen from a set of mutually unbiased bases (MUBs). The advantages of such spreading with MUBs are that multiple base stations (110, 120) can send their pilot signals on a same time-frequency resources, making the pilot signal design very efficient and also improving channel estimation at a user equipment (102, 103) through orthogonal and quasi-orthogonal spreading which gives a gain above noise and interference. A short spreading code chosen from MUBs may be used for spreading pilot signals transmitted from each antenna of a base station within a time-frequency resource comprising multiple closely-spaced subcarriers in frequency and/or multiple closely-spaced symbols in time.

摘要： A method an apparatus is described for providing feedback for closed-loop transmitting with multiple transmit and receive antennas. The method includes a first step (900) of providing a codebook containing sets of weightings for each data stream of the multiple transmit antennas with each set identified by an index known to a transmitter and a receiver. The same codebook is utilized for any number of data streams up to the number of transmit antennas. A next step (902) includes measuring a composite channel between the transmitter and receiver. A next step (904) includes determining at least one performance metric for each set of weightings in the codebook. A next step (906) includes selecting preferred weightings for each data stream in response to the performance metrics. A next step (908) includes feeding back an index of the preferred weightings to the transmitter for use in subsequent transmissions.

摘要： A method and apparatus for performing spatial-division multiple access within a communication system is provided herein. During operation, nodes will return null subspace information along with their channel subspace information. The null subspace is similar to the channel subspace except that the null subspace information directs a base station to the matrix in a predefined codebook that results in minimum power being received at the node. The null subspace for each node is taken into consideration when communicating with a particular node.

摘要： Cyclic-shift diversity transmission and optional per-subcarrier transmit beamforming within a same time interval (e.g., OFDM symbol interval) takes place. The CSD transmission technique circularly shifts the IFFT output prior to any cyclic prefix insertion and has the effect of putting a subcarrier and antenna dependent phase shift in the effective channel response from each transmit antenna. To properly perform transmit adaptive array (TXAA) transmission within an OFDM symbol interval that is being circularly shifted by the CSD transmission technique, the TXAA weights will account for the frequency domain phase shift created by the CSD circular shift operation.
摘要翻译：发生在相同时间间隔（例如，OFDM符号间隔）内的循环移位分集传输和可选的每副载波发射波束形成。 CSD传输技术在任何循环前缀插入之前循环移位IFFT输出，并且具有将每个发射天线的有效信道响应中的副载波和天线相关相移放在有效信道响应中的作用。为了在通过CSD传输技术循环移位的OFDM符号间隔内适当地执行发射自适应阵列（TXAA）传输，TXAA权重将考虑由CSD循环移位操作产生的频域相移。

摘要： A pilot transmission scheme is presented where during a first OFDM symbol period a first pilot sequence is transmitted over multiple sub-carriers on a first group of antennas. During a second OFDM symbol period, a second pilot sequence is transmitted over the multiple sub-carriers on a second group of antennas. The first group of antennas does not transmit pilot sequences when the second group of antennas is transmitting pilot sequences. Additionally, the second group of antennas does not transmit pilot sequences when the first group of antennas is transmitting pilot sequences.

摘要： A method and apparatus for determining stream weights is provided herein. During operation, an uplink direction of arrival (DOA) and a downlink direction of departure (DOD) calibration procedure is implemented using uplink signals and GPS information from a subset of mobiles without the need of calibration circuitry at the base. Because the presented calibration procedure needs no new hardware it can be deployed in existing deployments with only a soft-ware upgrade.
