摘要： The iterative decoding of blocks may be continued or terminated based on CRC checks. In an example embodiment, one iteration of an iterative decoding process is performed on a block whose information bits are covered by a CRC. The iterative decoding process is stopped if the CRC checks for a predetermined number of consecutive iterations. In another example embodiment, a decoding iteration is performed on a particular sub-block of multiple sub-blocks of a transport block, which includes a single CRC over an entirety of the transport block. The CRC is checked using decoded bits obtained from the decoding iteration on the particular sub-block and decoded bits obtained from previous decoding iterations on other sub-blocks of the multiple sub-blocks. The decoding iteration is then performed on a different sub-block if the CRC does not check. Also, the decoding iterations for the sub-blocks may be terminated if the CRC checks.

摘要： A base station maximizes a uplink data transmission rate from multiple mobiles treated by the base station as a virtual single uplink transmitter. The base station identifies a set of mobile stations as a candidate transmitting set and determines a transmit power allowable from the mobile stations in the candidate transmitting set. A subset of those mobile stations in the candidate transmitting set is identified. Uplink data transmission rates are assigned and communicated to the subset of mobile stations in the candidate transmitting set so as to optimize a total number of bits processed by the base station associated with the uplink transmissions received from the subset of candidate mobile stations. The optimization may accomplish one or more objectives in addition to optimizing the total number of bits processed.

摘要： A mobile terminal in a wireless communication network detects congestion and lowers its vocoder source rate in response, to help alleviate the congestion. The mobile terminal may detect the congestion in a variety of ways. The mobile terminal may monitor bandwidth allocation in the network, such as by inspecting the UL-MAP and DL-MAP of an IEEE 802.16 OFDM Physical Layer Frame header, for symmetric allocations. Congestion may be defined by the number of symmetric allocations exceeding a threshold. The congestion threshold may be programmed into the mobile terminal, or may be transmitted by the network. The mobile terminal may infer congestion by being repeatedly granted less bandwidth than requested. The network my explicitly indicate congestion, in a MAC message or by setting a congestion flag in one or more voice data frames. The congestion flag may comprise a reserved encoding of the AMR header Frame Type field.

摘要： A broadcast-centric cellular communication system improves broadcast channel performance by exploiting the benefits of macro-diversity in a cellular communication system having a plurality of base stations that transmit signals within a plurality of associated cells. System-specific control information common to all cells is synchronously and simultaneously broadcast from multiple base stations using a broadcast channel that is identical across the entire system. Cell-specific control information is transmitted individually from each base station. Mobile stations use the broadcast information for initial synchronization to the system, and to obtain most relevant system information. After system synchronization, the mobile stations identify the connected cell through a physical layer characteristic, and perform initial access to the system.

摘要： A first status report is generated based on initial data that has been received, such as from a mobile communications device and/or a packet network. The first status report is compressed to generate a first compressed status report. The first compressed status report is updated to generate a second compressed status report based on further data received after beginning the compressing of the first status report. The further data may be received as coded data prior to beginning the compression of the first status report but not decoded and determined to have a received status until after beginning the compression of the first status report, and/or the further data may not have been communicated until after the compression has begun and/or completed.

摘要： The present invention relates to methods and systems for wireless communication wherein a plurality of narrowband carrier frequencies is overlaid with at least one wideband carrier frequency. In particular, the present invention relates to maintaining radio communication on the narrowband carrier frequencies closest to the edge of the bandwidth of the wideband carrier frequency in order to reduce system interference. This is accomplished by using frequency hopping to preferentially switch radio communication to narrowband carrier frequencies closest to the edge of the bandwidth of the wideband carrier frequency. Thus, the present invention discloses systems and methods which allow several communication devices to occupy the same frequency spectrum while maintaining interference at acceptable levels.

摘要： A digital subscriber loop (DSL) modem and methods for controlling a DSL modem are provided which support simultaneous voice and data communications, wherein the voice communication is provided in a first frequency range and the data communication is provided in a second, non-overlapping frequency range. A voice communication is detected in the first frequency range and the output power associated with the data communication in the second frequency range is reduced when a voice communication in the first frequency range is detected. Furthermore, the coding level associated with the data communication in the second frequency range may be increased when a voice communication in the first frequency range is detected. Also, the start frequency associated with data communication in the second frequency range may be increased when a voice communication in the first frequency range is detected.

摘要： A received signal processing circuit for a receiver in a digital communication system uses a re-encode and compare scheme to measure received signal quality. The received signal is demodulated and decoded to produce an estimate of the original information bit sequence. The estimate of the information bit sequence is re-encoded using the same channel code as the transmitter. The re-encoded bits are compared to the demodulated bits output from the demodulator to yield an initial estimate of the channel bit error rate caused by the communication channel. Bias in th4e initial estimate of the channel bit error rate is removed to produce a refined estimate of the channel bit error rate.

摘要： A method and associated circuitry for initiating communication between a network station and a user terminal of a radiotelephonic communication system, such as a satellite-cellular communication system. When communication is to be initiated, a paging signal is transmitted by a network station to the user terminal. When the user terminal detects the paging signal, an acknowledgment signal is generated by the user terminal and encoded to increase the margin of the acknowledgment signal. Upon reception, the acknowledgment signal is correlated using a multiplicity of correlators. An increased margin acknowledgment signal acknowledging reception of the paging signal is transmitted to facilitate communication of the acknowledgment signal back to the network station.

摘要： A telecommunications system and method for minimizing interruptions to voice transmissions due to the transmission of overriding control signals is disclosed. Since FACCH and other control signals replace or block-out speech data, the quality of speech transmissions deteriorates the longer the control transmission. Through modifications to the FACCH protocol, lengthy sequential FACCH or other control transmissions are divided into a plurality of discrete control segments, which are transmitted non-sequentially throughout a speech transmission, and queued at the receiving end. After receipt of all of the control segments, the original control message is reconstructed and forwarded for processing.
