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： Method and apparatus for enabling accurate link quality estimation of a wireless link between a sending node and a receiving node. When the sending node receives link state reports from the receiving node, it estimates the current state of the wireless link. The sending node also determines a measurement adjusting parameter if the link state reports are deemed inaccurate in relation to the estimated link state, based on a deviation between the received link state reports and the estimated actual link state. The sending node then sends the determined measurement adjusting parameter to the receiving node, and the receiving node provides a link state report based on signal measurements adjusted by the measurement adjusting parameter. The adjusted link state report can then be used for link adaptation of the wireless link and/or for packet scheduling decisions.

摘要： A receiving unit or a transmitting unit of a wireless network, and method therefor, for facilitating noise and interference measurements on an air interface. The receiving unit includes: a network interface which obtains information relating to a time-varying layout of a silent resource element (RE) grid; an electronic memory having code in communication with the network interface which stores the information; and a processing unit in communication with the electronic memory that takes a presence of a silent RE grid into account in the reception of a control or a data channel. Information relating to a time-varying layout of a silent resource element (RE) grid is obtained and a presence of a silent RE grid is taken into account in the reception of a control or a data channel.

摘要： The invention relates to a method and an arrangement in a transmitting node (560) for enabling a receiving node (540) to perform measurements on interference caused by transmissions from at least one transmission point (510, 520, 530) controlled by the transmitting node (560) on receptions at the receiving node (540). The transmitting and receiving nodes (560, 540) are comprised in a wireless communications system (500, 600, 700). The transmitting node determines (910) an interference measurement resource, IMR, comprising a set of Time-Frequency Resource Elements, TFREs, upon which the transmitting node is expected to transmit interference. The transmitting node then transmits (930) at least one interfering signal on said IMR as said interference. The at least one interfering signal comprises at least one of a desired signal, that is expected to be decoded or coherently measured upon by the receiving node (540) or another node (550) served by said transmitting node (560), and another signal, that is not expected to be decoded or coherently measured upon by any node (540, 550) served by said transmitting node (560). The desired signal is transmitted in place of the another signal as said at least one interfering signal on one or more TFREs of the IMR when the at least one transmission point is to transmit the desired signal to the receiving node (540) or to the another node (550). The another signal is transmitted on TFREs of said IMR where no desired signal is transmitted and the another signal is muted on TFRE's of said IMR where the desired signal is transmitted.

摘要： A method and radio node (500) for enabling higher-order modulation in a radio communication with a first UE (502). A first table configuration comprises at least one of a first Modulation and Coding Scheme, MCS, table and a first Channel Quality Indicator, CQI, table which tables support a certain maximum modulation order. When the radio node (500) detects that a modulation order higher than the maximum modulation order of the first table configuration is potentially possible to use in the radio communication, the radio node (500) instructs the first UE (502) to apply a second table configuration which comprises at least one of a second MCS table and a second CQI table which second tables support the higher modulation order. At least one entry for at least one modulation order in the tables of the first table configuration is maintained in the tables of the second table configuration as a fall-back in case it is desirable to use the at least one modulation order of the first table configuration when the second table configuration is applied. Thereby, a higher data rate can be achieved in the radio communication.

摘要： Methods for wirelessly transmitting user data and control information using a plurality of transmission layers include encoding bits of control information to form control codewords and encoding bits of user data to form 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 control codewords and bits of the user data codewords so that the control information is carried in modulation symbols associated with the same transmission layers in the vector symbols transmitted during the subframe that carry the control information. The method also includes transmitting the plurality of vector symbols to a receiver over a plurality of transmission layers.
