摘要： A method, apparatus and computer program product are provided for conveying information regarding the antenna configuration and/or the transmission diversity scheme to a recipient, such as a mobile device. In particular, information regarding the antenna configuration and/or the transmission diversity scheme can be conveyed by appropriately mapping a physical broadcast channel within a sub-frame so as to include reference signals indicative of different antenna configurations or transmission diversity schemes. Alternatively, masking, such as cyclic redundancy check masking, can be used to provide information regarding the antenna configuration and/or the transmission diversity scheme.

摘要： A method can include providing channel feedback to support efficient rank override For example, in such a method, a rank−r precoder index corresponding to a rank−r precoder is determined, and performance for each rank−1 precoder within the rank−r precoder is measured Based on the measured performance, a rank−1 precoder that maximizes performance is selected

摘要： In an embodiment, state of a wireless channel on which information is received is measured; the measured state is used to select from a codebook a plurality of N codewords which optimize a predefined measure, and first and second codewords of the plurality are reported which best optimizes and next-best optimizes the predefined measure. If by example the above is done by a user equipment UE, in another embodiment the network receives first and second indications, searches a codebook using the first and second indications to find the first and second codewords; and utilizes them to improve the channel state information, such as by interpolating between them to find an estimate of the channel. In examples the channel is a MIMO channel that is estimated at two or more antenna ports, there are interpolation weights sent with the codeword indications, and the interpolating uses a geodesic algorithm.

摘要： Disclosed is a method, apparatus and a computer readable memory medium that stores a program of computer instructions for enabling a resource allocation to be made for user equipment. The method includes forming a resource allocation for a particular system bandwidth, where the resource allocation has a larger number of resource blocks than a maximum number of resource blocks associated with the particular system bandwidth, while maintaining a same resource block group size as would be present with the maximum number of resource blocks for the particular system bandwidth. The step of forming includes the use of an extended parameter in a derivation of the resource allocation. The method further includes transmitting information descriptive of the resource allocation to user equipment. The resource allocation may be a downlink resource allocation or an uplink resource allocation.

摘要： Precoding information is provided (implicitly or explicitly) to a particular user equipment UE. Closed-loop spatial coding for a control channel is selected for the particular user equipment, and at least one control channel element CCE is determined within the particular user equipment's search space of the control channel that is associated with the provided precoding information. The determined at least one CCE is spatially encoded using the provided precoding information to schedule radio resources for the particular user equipment. The UE determines a search space for a control channel, and from received radio resource control signaling determines at least one CCE within the search space that is to be encoded with closed-loop spatial coding. The UE decodes the determined at least one CCE within the search space using a closed-loop spatial decoding with precoding information associated with the at least one CCE to find radio resources scheduled for the particular UE.
