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： A method for wirelessly transmitting user data and at least a first type of control information using a plurality of transmission layers including encoding bits of a first type of control information to form one or more control codewords and encoding bits of user data to form one or more user data codewords. The method also includes generating a plurality of vector symbols based on the control codewords and the user data codewords. Each vector symbol includes a plurality of modulation symbols that are each associated with a transmission layer over which the associated modulation symbol will be transmitted. Generating the plurality of vector symbols includes interleaving bits of the one or more control codewords and bits of the one or more user data codewords so that the first type of control information is carried in modulation symbols associated with the same transmission layers in all the vector symbols transmitted during the subframe that carry the first type of control information. The method also includes transmitting the plurality of vector symbols to a receiver over a plurality of transmission layers.

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： 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 method in a radio base station for transforming a data transmission signal in a radio communications network. The radio base station is connected to an active antenna array of a first number of active transmitting antennas, which each active transmitting antenna comprises sub elements. The radio base station comprises a precoder codebook comprising precoders for transmitting signals in a diversified manner for a second number of antenna ports. The radio base station precodes the data transmission signal with a precoder selected from the precoder codebook. The radio base station furthermore transforms, linearly, the precoded data transmission signal by neutralizing a direction of the precoded data transmission signal and then directing the precoded data transmission signal vertically. The precoded data transmission signal is thereby enabled to be vertically adjusted towards a user equipment in the radio communications network.

摘要： Determining transmitter antenna weights at a base station having more available transmit antennas than the available number of reference signals can be performed by transmitting reference signals and receiving channel feedback data derived by a mobile terminal from the reference signals. The reference signals are each assigned to one of two or more antenna groupings, wherein at least a first one of the antenna groupings includes two or more transmit antennas, and transmitted using at least one transmit antenna from the corresponding antenna grouping. A first beam-forming vector for the first one of the antenna grouping is determined, and mapping the one or more data streams to the transmit antennas according to a final precoding matrix that depends on the channel feedback data and the first beam-forming vector is performed, to obtain a weighted transmit signal for each of the antennas.

The first node communicates with the second node in a wireless communication system (110) over a radio link (130).
