摘要： A user terminal, a communication network, a computer readable medium and a method for selecting at the user terminal a reception and decoding of a transmission mode used by a base station, the user terminal receiving communicated information from the base station, which has multiple antennas, via plural channels, the plural channels including a primary broadcast channel and at least one control channel. The method includes receiving at the user terminal initiating data from the base station via the primary broadcast channel, detecting from the received initiating data whether a first or a second transmission mode is used by the base station for the primary broadcast channel, the first transmission mode indicating that a first number of antennas are used by the base station and the second transmission mode indicating that a second number, different than the first number, of antennas are used by the base station to communicate with the user terminal, and using the detected first or second transmission mode of the primary broadcast channel to decode the at least one control channel.

摘要： Systems and methods are disclosed for using multiple configuration groups having corresponding configuration identity (CID) parameters to configure a transmission channel and a reception channel for a user equipment device in a cellular communication network. In one embodiment, a user equipment device in a cellular communication network obtains CID values for CID parameters for a number of configuration groups. Each of the configuration groups includes one or more transmission channel or reception channel parameters. For each of the configuration groups, the user equipment device configures the parameters in the configuration group based on the CID value obtained for the CID parameter for the configuration group. In this manner, the transmission channel and the reception channel for the user equipment device are configured based on multiple CID values rather than a single physical layer cell identifier for a cell in which the user equipment device is located.

摘要： A high-power point (110) and one or more low-power points (120) transmit signals that are associated with the same cell-identifier in a heterogeneous cell deployment. The coverage areas corresponding to the low-power points (120) fall at least partly within the coverage area for the high-power point (110), so that mobile stations (130) within range of a low-power point are also within range of the high-power point (110), from a downlink perspective. The same CRS signals are transmitted by both the high-power (macro) point (110) and some or all of the low-power (pico) points (120). At the same time, the network transmits CRS-based PDSCH for a particular UE on both the high-power point (110) as well as on some or all of the low-power points (120). In some embodiments only a subset of the points, e.g., those points that the UE hears sufficiently well, participate in the PDSCH transmission using CRS for channel estimation.

摘要： A method for wirelessly transmitting data and control information using a plurality of transmission layers includes determining a number of bits in one or more user data codewords to be transmitted during a subframe and calculating, for each of M control signals to be transmitted during the subframe, a value (Q′), based at least in part, on the number of bits in the one or more user data codewords, and an estimated number of user data vector symbols onto which the one or more user data codewords will be mapped. The estimate of the number of user data vector symbols for a particular one of the M control signals depends, at least in part, on a number of control vector symbols to be allocated to one or more others of the M control signals. The method also includes determining a number of control vector symbols onto which to map each of the M control signals based on a respective value Q′ calculated for that control signal, mapping the control signals for that control signal, and transmitting the control vector symbols.

摘要： One aspect of the teachings herein relates to signaling codebook restrictions, to restrict the precoder recommendations being fed back from a remote transceiver, so that precoder selections made by the remote receiver are restricted to permitted subsets of overall precoders within a defined set of overall precoders, or to permitted subsets within larger sets of conversion precoders and tuning precoders, for the case where the overall precoders are represented in factorized form by conversion and tuning precoders. As a non-limiting example, these teachings advantageously provide for precoder restrictions in LTE or LTE-Advanced networks, where ongoing development targets the use of larger, richer sets of precoders, and where the disclosed mechanisms for determining, signaling, and responding to subset restrictions provide significant operational advantages.

摘要： A precoder for an effective channel linking a wireless receiver to a wireless transmitter includes a precoder report and a precoder update report, the effective channel including a propagation channel, transmit filters and receive filters. A structured frequency-selectivity of the effective channel is determined, the structured frequency-selectivity being induced by one or more long term and/or persistent parameters of the effective channel. The precoder update report is generated based on the structured frequency-selectivity. The precoder update report includes frequency-dependent phase compensation which accounts for the structured frequency-selectivity. The precoder report is generated for the effective channel based on channel state information determined for the effective channel. The precoder report and the precoder update report are transmitted to the wireless transmitter. The transmitter determines a transmission operation based on the precoder report and the precoder update report, and transmits data to the wireless receiver in accordance with the transmission operation.

摘要： Techniques are disclosed for determining transmitter antenna weights at a base station (12) having more available transmit antennas (150) than the available number of reference signals. An exemplary method includes transmitting (530) a plurality of reference signals and receiving (540) channel feedback data derived by a mobile terminal (14) from the reference signals. The reference signals are each assigned to a corresponding one of two or more antenna groupings, wherein at least a first one of the antenna groupings comprises two or more transmit antennas (150), and transmitted using at least one transmit antenna (150) from the corresponding antenna grouping. The method further includes determining (550) a first beam-forming vector for the first one of the antenna grouping and mapping (570) the one or more data streams to the transmit antennas (150) according to a final precoding matrix that depends on the channel feedback data and the first beam-forming vector, to obtain a weighted transmit signal for each of the antennas (150).
