摘要： Methods and apparatus are described for improving convergence time of a reference signal-to-interference (SIR) value calculated in outer loop power control for use in inner loop power control. Instead of considering only error rate information for each transport channel individually, other information, such as quality information from other transport channels and block rate information for the channel, is also considered to determine the reference SIR. By considering such other information, an improved outer loop power control is achieved, thus reducing the power needed for the physical channel and increasing the capacity of the communication system.

摘要： A method and apparatus for processing a received signal containing a desired burst and a co-channel interferer burst are disclosed. The invention includes receiving the received signal from a front end receiver. A time offset betweeen the desired burst and the co-channel interferer burst is detected. A detection procedure is then selected based on the time offset between the desired burst and the co-channel interferer burst. Preferably, one of three detection procedures is selected based on the time offset detected and optionally the signal strength of the co-channel interferer burst. If a first or second time offset is detected, then a joint detection or an iterative detection procedure is selected and performed, respectively. Finally, if a third time offset is detected or if the co-channel interferer has a low signal strength, then a conventional detection procedure is selected and performed.

摘要： Link quality control information is generated by receiving a received signal from a front end receiver. Time dispersion information is then estimated during a synchronization of the received signal. Then, link quality control information is generated using the time dispersion information. The link quality control information includes information pertaining to an optimal tansmission parameter. The link quality control information can be transmitted back to a unit that transmitted the received signal so that the appropriate transmission parameters may be adjusted.

摘要： A base station receives channel quality reports from a plurality of mobile terminals. The channel quality reports from the mobile terminals indicate the signal power of the signals received by the mobile terminals from the base station and one or more interference parameters relating to the power of impairment components contributing to the total impairment of the received signal during a first time interval. The base station computes an estimated channel quality indication for a second time interval subsequent to the first time interval based on expected variations in the powers of the impairment components. The estimated channel quality indication for the second time interval is used by the base station to schedule the mobile terminals and to determine the transmission format.

摘要： Adaptation is introduced into allocation of uplink and downlink subframes in wireless communication systems that support full-duplex and half-duplex mobile terminals, thus reducing interference between mobile terminals. In an exemplary method for allocating uplink and downlink timeslots in a wireless communication system supporting full-duplex and half-duplex mobile terminals, a base station determines that a mobile terminal is capable of only half-duplex operation and allocates one or more uplink subframes and one or more downlink subframes to the first mobile terminal, for each of a plurality of frames, so that none of the allocated uplink subframes overlaps in time with an allocated downlink subframe. The allocation of uplink subframes and downlink subframes is varied between consecutive ones in at least a first series of frames according to a pre-determined pattern. In some embodiments, the method further includes transmitting an allocation message to the first mobile terminal, designating the pre-determined pattern.

摘要： Channel estimation is performed by user equipment operating in a mobile communications system. Estimation involves receiving a signal and analyzing it to detect a signal component from a neighboring cell. Depending on outcome, one or both of the following are determined: whether a power level of the signal component from the neighboring cell exceeds a power threshold level; and whether a difference between timing parameters of the neighboring cell?s signal component and that from a serving cell is less than a timing threshold level. If the power level of the neighboring cell?s signal component exceeds the power threshold level and the difference between the timing parameters of the signal components from the neighboring cell and that of the serving cell is less than the timing threshold level, then a joint channel estimation process is performed. Otherwise, a single channel estimation process is performed.

摘要： A pre-coding matrix is determined in an OFDMA, multiple transmit antenna communication system having a number of sub-carriers grouped into a number, M, of resource blocks. This involves determining a frequency selectivity of a channel through which received signals have propagated. A number N of selected resource blocks is then determined as a function of the frequency selectivity the N selected resource blocks being those for which pre-coding matrices will be determined, wherein N. The pre-coding matrices are then determined for the N selected resource blocks. Pre-coding matrices for a remaining M-N of the M resource blocks are determined by means of interpolation applied to the N pre-coding matrices determined for the N selected resource blocks.
