摘要： A base station for wireless network uses one or more MIMO channels having subchannels, to communicate with multiple user equipments, and allocates the sub channels to the user equipments. Different subchannels of a given one of the channels can be allocated to different user equipments. The ability to allocate sub channels individually rather than only allocating entire channels can enable higher data rates can be achieved. This is particularly useful for improving data rates at cell boundaries or sector boundaries, where the coverage is traditionally weakest. A user equipment can use subchannels from different MIMO channels from different sectors or from different base stations.

摘要： The invention relates to improving the quality of a received downlink signal in a time division multiple access wireless cellular communications network. The method of the invention comprises measuring a signal quality characteristic at a user equipment and comparing this to a threshold to determine if a desired signal quality level exists. If so then a certain level or type of service on the downlink can be effected. If not, the method comprises identifying an interferer signal or signals and removing at least one of such interferer signals by arranging for it to either not be transmitted on the same TDMA timeslot as the downlink signal or to be transmitted at a lower power, for example, in said timeslot.

摘要： Disclosed is an apparatus for reducing the number of control signal channels required in a wireless communication system by using a umbrella control signal to initially communicate with an MS (mobile station) within the umbrella and to assign the MS to a traffic frequency corresponding to one of a plurality of antenna used to cover the area covered by said umbrella control signal. Logic is used in combination with measured relative signal strengths to determine the position of the MS relative to the reliable reception coverage area of each of the plurality of antennas before the assignment is made.

摘要： A base station for a wireless network has multiple channels for communicating with user equipments, and has multiple channel reuse patterns. The patterns are complementary such that areas of low carrier to interference ratio C/I of one pattern are not coincident with areas of low C/I of other patterns. An allocator allocates channels such that for user equipment located in an area of low C/I of any of the complementary patterns, the allocator favors allocation of a channel of another of the complementary patterns. The sacrifice of capacity can be reduced as there is less need for a capacity-hungry high re-use factor pattern. The channels may be frequencies, time slots or CDMA codes. The reuse patterns can involve reuse on selected base stations, or on selected sectors, or different polarizations. The network can be of any type including fixed wireless access FWA, or mobile networks.

摘要： Methods of improving channel estimation are described, in which pilot symbols are inserted into orthogonal frequency division multiplexing (OFDM) frames at an OFDM transmitter having at least one transmitting antenna, wherein for the or each antenna, historical data regarding channel conditions is obtained so that the scattered pilot symbols are inserted in a scattered pattern dependent upon said historical data. Alternatively, or in addition, an adaptive channel estimation filter is used whose parameters are selected according to analysis of historical data regarding channel conditions.
