摘要： A UE system implements dynamic link adaptation by adding or changing control information to notify a receiver which timeslots and codes are currently active and which timeslots should be avoided. The UE provides synchronization such that the receiver knows which timeslots and codes the UE has used to map the coded composite transport channel onto physical channels. The UE attempts to avoid the timeslots which are experiencing transmission difficulties, while attempting to utilize the timeslots which are not experiencing transmission problems.

摘要： A method for a base station to optimize radio resource utilization and adjust data rates in a wireless digital communications system. The base station communicates with a plurality of user equipment mobile terminals (UEs) and employs adaptive modulation and coding (AM&C) to achieve improved radio resource utilization and provide optimum data rates for user services. Blocks of downlink (DL) data are received by the base station which requests downlink DL channel quality measurements only from those mobile terminals (UEs) with pending downlink transmissions. The UEs respond to the request by measuring and reporting DL channel quality to the base station, which then allocates resources such that the UEs will make best use of radio resources. The base station notifies the UEs of the physical channel allocation indicating the modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs.

摘要： A method of using a user equipment (UE) in a wireless time division duplex communication system. Each communication burst has a unique channelization code and a midamble code which is uniquely related to the channelization code, each such midamble code being uniquely related to one or more channelization code. The UE receives communication bursts and detects each midamble code in a received communication burst. The UE determines the channelization codes related to each detected midamble based on a mapping of midamble codes to related channelization codes. The UE detects channelization codes in the received communication burst from among the determined channelization codes.

摘要： A method of using a mobile unit in a multi-cell communication system to determine whether to commence handover of the mobile unit from a serving base station located in a first cell of the communication system to a target base station located in a second cell of the communication system. The mobile unit determines the serving base station received signal code power (RSCPser), the first cell interference signal code power (ISCPser), the target base station received signal code power (RSCPtar) and the second cell interference signal code power (ISCPtar). If the ratio RSCPser/ISCPser is less than the ratio RSCPtar/ISCPtar, the mobile unit commences handover to the target base station. The multi-cell communication system may be a time division duplex (TDD) system. The mobile unit may send a message to a radio network controller (RNC) in communication with the serving and target base stations to initiate the handover.

摘要： A method and apparatus for implementing spatial processing with unequal modulation and coding schemes (MCSs) or stream-dependent MCSs are disclosed. Input data may be parsed into a plurality of data streams, and spatial processing is performed on the data streams to generate a plurality of spatial streams. An MCS for each data stream is selected independently. The spatial streams are transmitted via multiple transmit antennas. At least one of the techniques of space time block coding (STBC), space frequency block coding (SFBC), quasi-orthogonal Alamouti coding, time reversed space time block coding, linear spatial processing and cyclic delay diversity (CDD) may be performed on the data/spatial streams. An antennal mapping matrix may then be applied to the spatial streams. The spatial streams are transmitted via multiple transmit antennas. The MCS for each data stream may be determined based on a signal-to-noise ratio of each spatial stream associated with the data stream.

摘要： In an orthogonal frequency division multiplexing (OFDM) system, a frequency domain channel estimate for non-nullified subcarriers is converted to a time domain channel estimate. The number of taps L of a channel model is determined based on the time domain channel estimate. An improved time domain channel estimate is obtained by computing L tap coefficients of the channel model from the frequency domain channel estimate. An improved frequency domain channel estimate is obtained by performing a Fourier transform on the improved time domain channel estimate. Alternatively, a time domain truncation method may be performed selectively only if the signal-to-noise ratio (SNR) is below a threshold. Alternatively, a frequency domain channel estimate for pilot subcarriers are converted to a time domain channel estimate and an improved frequency domain channel estimate is obtained based on the number of pilot subcarriers and a delay spread.

摘要： A method and system for controlling access to a wireless communication medium are disclosed. The system includes at least one access point (AP) and at least one station (STA). The AP defines a superframe for transmission of data in a time domain having a high throughput (HT) period which includes at least one scheduled resource allocation (SRA) and at least one management SRA (MSRA). The AP broadcasts an extended beacon (EB) including information about the SRA and MSRA. The SRA is defined for transmitting traffic data between the AP and the STA, and the MSRA is defined for transmitting management and control data between the AP and the STA. The system reduces station battery consumption, supports higher throughput for non-real time (NRT) traffic and is more efficient for real time (RT) traffic while maintaining full compatibility.
