摘要： The present invention sends multiple versions of a multimedia packet to the base station, and, based on the radio channel and traffic characteristics, an appropriate version of the multimedia packet is selected to send to the mobile station at a given time. In this way, source transmission is improved to instantaneous conditions. The steps of the present invention are performed in conjunction with RTP used for multimedia transmission over internet protocol (IP) networks. In a first embodiment, the multiple versions are sent to the base station in the same RTP packet, and the base station strips out the extraneous versions. In a second embodiment, the base station receives multiple RTP packets having identical information in the packet header in many fields, and selects an appropriate one among these for transmission to the mobile station, discarding the rest.

摘要： Frames of information are communicated between a base station (28) of a radio access network (RAN) and plural types of wireless terminals (30). Frame handlers of the base station and of certain types of wireless terminals (30-2) process differing portions of the frame according to respective differing multiple access technologies. In differing embodiments and implementations, modulation techniques of the differing multiple access technologies can be apportioned to differing portions of the frame in various manners, such as (for example) to differing subframes of a multi- sub-framed frame or to differing burst fields or sections of an uplink (UL) burst.

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： Methods and apparatus by which receiving stations or other communication network nodes can receive quick paging code words assigned by transmitting stations to the receiving stations. A receiving station can estimate the characteristics of the channel to the transmitting station based on a downlink-frame's preamble and use correlation to detect the presence of an assigned code word. The receiving station can suppress interference from other transmitting stations in the correlation operation based on the nature of the interference signal. When the receiving station knows an interfering signal from another transmitting station, the receiving station can subtract the interfering signal before carrying out the correlation operation.

摘要： A base station in an OFDMA system which determines a modulation and coding scheme to use for a packet of a certain size to be transmitted by a Mobile Station. The base station schedules transmissions by mobile stations and transmits packets. The base station includes a processing unit which determines a number of time-frequency resources required to transmit the packet for a modulation and coding scheme, determines an SlNR based on the number of time-frequency resources used and available power at the mobile station, determines a transmission rate as a ratio of the packet size transmitted to the number of time-frequency resources used, sets a rate to zero if the determined SlNR is lower than a threshold SINR required for the modulation and coding scheme, and selects the modulation and coding scheme with a highest transmission rate. The base station includes a memory storing modulation and coding schemes.

摘要： The present invention provides systems and methods that enable a base station to consume less power. According to an embodiment of the invention, the base station reduces its power consumption by not continuously broadcasting control information. In such an embodiment, a mobile station that seeks access to a network to which the base station provides access does not search for broadcast control information prior to transmitting an access message to the base station, but rather simply transmits on a predetermined access channel an access request message. A base station that receives the access request message may unicast control information to the mobile station.

摘要： Control of the transmission of streaming data between a first data processing system and a second data processing system in a packet network is provided. Priorities are assigned to packets of the streaming data based on characteristics of the packets of streaming data. Performance of transmission of the packets from the first data processing system to the second data processing system is monitored and retransmission of selected ones of the packets from the first data processing system to the second data processing system is terminated based on the assigned priority of the selected ones of the packets and the monitored performance of transmission. The streaming data may be progressively encoded. Furthermore, the priorities assigned to the packets of streaming data may be based on the level of progressive coding associated with a packet of data.

摘要： Teachings presented herein offer reduced computational complexity for symbol sequence estimation, and also provide for the generation of soft bit values representing the reliability of that estimation. A demodulator is configured to generate these soft bit v allies by identifying a candidate value for each symbol in the sequence which is more likely than at least one other in a defined set of candidate values. Based on the candidate value identified for each symbol, the demodulator forms a reduced set of candidate values for the symbol by selecting as many additional candidate values from the defined set as are needed to have complementary bit values lot each bit value in that identified candidate value The demodulator calculates soft hit values for the symbol sequence based on a sequence estimation process w hose state space for each symbol is constrained to the cot responding reduced set.
