摘要： Embodiments herein relate to a method in a radio base station (12) for transmitting a data signal to a user equipment (10) in a radio communications network. The radio base station (12) is connected to an active antenna array of a number of active transmitting antennas and the radio base station (12) serves the user equipment (10) in the radio communications network. Each active transmitting antenna comprises sub elements. The radio base station (12) transforms a precoded data signal using a transformation, which transformation directs signals vertically. Furthermore, the radio base station (12) transmits the transformed data signal over at least one sub element to the user equipment (10). The transmitted data signal is enabled to be directed vertically, and the transformed data signal is limited to be transmitted in a direction within a range of elevation angles.

摘要： Interference is estimated in an Orthogonal Frequency Division Multiplexing system by receiving at a wireless receiver pilot symbols and data symbols transmitted in time and frequency via resource blocks, detecting a first one of the data symbols transmitted to the wireless receiver via a time-frequency resource element of a first one of the resource blocks and identifying a second one of the resource blocks adjacent the first resource block having related interference parameters. The interference is estimated based on the pilot symbols transmitted via the first resource block and the pilot symbols transmitted via the second resource block.

摘要： Data is transmitted over multiple input multiple output (MIMO) channels. Plural bit streams are modulated into multiple data symbol vectors. Each vector has a transmission rank with one vector for each MIMO channel. Transmission rank is the number of elements in a data symbol vector corresponding to the number of data streams being transmitted in parallel over each MIMO channel. The multiple data symbol vectors are preceded into multiple precoded symbol vectors using a plurality of precoder cycling sets, one set for each transmission rank including multiple different precoders. The precoders in each precoder cycling set are well-separated with respect to a plurality of distance measures. The precoding includes precoding each data symbol vector of a transmission rank with a precoder belonging to the precoder cycling set of that transmission rank. The precoded symbol vectors are then transmitted over the MIMO channels.

摘要： A method of conveying transport block size (TBS) information includes determining TBS parameters for a wireless transmission of data between a first node and a second node based on a first number of transmission layers associated with the wireless transmission. The method also includes generating a control message indicating the TBS parameters and transmitting the control message to the second node.

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： The present invention provides a unified, rank independent mapping between antenna ports and group/code pairs. Each antenna port is uniquely associated with one code division multiplexing (CDM) group and one orthogonal cover code (OCC). The mapping between antenna ports and group/code pairs is chosen such that, for a given antenna port, the CDM group and OCC will be the same for every transmission rank.

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： A high-power point and one or more low-power points transmit signals associated with the same cell-identifier in a heterogeneous cell deployment. Coverage areas corresponding to the low-power points fall at least partly within the coverage area for the high-power point, so that mobile stations within range of a low-power point are also within range of the high-power point. Channel-state-information reference symbols, CSI-RS, are transmitted using different CSI-RS resources on different transmission points within the cell, while configuration of CSI-RS measurement resources is conducted on a UE-specific basis. The choice of measurement resources to be used is determined by the network, based on the properties of the channels from the transmission points to the UE. As the UE moves around within the cell, the network tracks the channel properties and reconfigures the CSI-RS resources measured by the UE, to correspond to the resource of the closest transmission point or points.

摘要： Systems and methods for generating a demodulation reference signal for use by user equipment configured with multiple antennas based on a rank of an antenna or an antenna port are disclosed. A rank for a user equipment device is determined indicating the number of spatial layers or antenna ports in use, and the value of the rank is used to generate a cyclic shift offset and a cyclic shift, that can then be used to generate a demodulation reference signal to be used in timeslots within each spatial layer of an uplink transmission. Orthogonal cover codes may be used in conjunction with a determined cyclic shift to generate a demodulation reference signal.
