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： 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： 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.

摘要： In a heterogeneous cell deployment a mobile terminal may need to receive control data transmissions from a macro node at the same time as a pico node is transmitting user data for the mobile terminal, using the same frequency or set of frequencies. This can result in a problematic interference situation. According to several embodiments of the present invention, at least one of two general approaches is used to mitigate the interference situation described above. In a first approach, the pico node's transmission power is reduced in some time intervals, thereby reducing the interference to a level where reception from the macro node is possible. In a second approach, which may be combined with the first approach in some cases, the data transmitted from the macro node is provided by the pico node, either alone or in combination with the macro 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： A method for wirelessly transmitting data using a plurality of transmission layers includes estimating a number of vector symbols to be allocated to transmission of user data codewords during a subframe and determining a number of bits in a plurality of user data codewords to be transmitted during the subframe. The method also includes calculating a number of control vector symbols to allocate to control information based at least in part on the estimated number of vector symbols and the determined number of bits. Additionally, the method includes mapping control codewords to the calculated number of control vector symbols and transmitting vector symbols carrying the user data codewords and the control codewords over the plurality of transmission layers during the subframe.

The method comprises transmitting (606) a configuration message to the UE. The configuration message comprises an indication of a first mapping of the ePDCCH to resource elements belonging to a first ePDCCH set, where the resource elements of the first ePDCCH set are different from resource elements used for a first type of signal. The method further comprises an indication of a second mapping of the ePDCCH to resource elements belonging to a second ePDCCH set, where the resource elements of the second ePDCCH set are different from resource elements used for a second type of signal, thereby enabling dynamically mapping ePDCCH to the resource elements of the first ePDCCH set or the second ePDCCH set. Further methods, UEs and computer programs are provided for communicating an ePDCCH between a network node and a UE.
