摘要： An apparatus and method for enhanced downlink processing of received channels in a mobile communications system is described, containing a buffer for control data and traffic data, a demapper engine with at least two independently operating demappers for demapping the control and traffic data, a log-likelihood-ratio (LLR) buffer for supporting memory segments accessible by the demapper engine, a decoder engine containing decoders, each of the decoders operating on data from selected memory segment(s) of the LLR buffer, and an arbitrator providing control of at least one of the demapper engine, LLR buffer, and decoder engine. At least one of the decoders is suited for decoding control data and another one of the decoders is suited for decoding traffic data. By partitioning the decoding as such, an increase in downlink throughput can be obtained.

摘要： A system involves a transmitting device (for example, a first wireless communication device) and a receiving device (for example, a second wireless communication device). In the receiving device, LLR (Log-Likelihood Ratio) values are stored into an LLR buffer. LLR bit width is adjusted as a function of packet size of an incoming transmission to reduce the LLR buffer size required and/or to prevent LLR buffer capacity from being exceeded. The receiver may use a higher performance demodulator in order to maintain performance despite smaller LLR bit width. In the transmitting device, encoder code rate is adjusted as a function of receiver LLR buffer capacity and packet size of the outgoing transmission such that receiver LLR buffer capacity is not exceeded. Any combination of receiver LLR bit width adjustment, demodulator selection, and encoder code rate adjustment can be practiced to reduce LLR buffer size required while maintaining performance.

摘要： Signaling is efficiently sent on a configurable CDMA control segment. To send signaling, transmission parameters for the CDMA control segment for a serving sector are determined. These parameter may indicate the CDMA control segment size, the frames in which the CDMA control segment is sent, the signaling channels to be sent on the CDMA control segment, and so on. The enabled CDMA signaling channels for a terminal and the average transmission interval for each enabled CDMA signaling channel are determined. For each frame in which the CDMA control segment is sent, the signaling channels to be sent on the CDMA control segment in that frame are determined. The signaling for each signaling channel is processed (e.g., encoded, channelized, scaled, and scrambled). The processed signaling for all signaling channels is combined and mapped to a time-frequency region used for the CDMA control segment in the frame.

摘要： Apparatus and methods for communicating and applying training sequences are described herein. For example, provided is a method for generating a short training field (STF) sequence comprising thirty two values or less. The STF sequence can include a first subset of values including zero and non-zero values. The non-zero values can be located at indices of the first subset that are at least a multiple of two, and can be a multiple of four. The STF sequence includes a second subset of zero values that can include all values not included within the first subset. The method further includes transmitting a data unit comprising the STF sequence over a wireless channel. In another example, a method is provided that includes generating a long training field (LTF) sequence comprising thirty two values or less, and transmitting a data unit comprising the LTF sequence over a wireless channel.

摘要： Methods and apparatuses are proposed for supporting one or more user-dependent channel state information (CSI) feedback rates in a downlink spatial division multiple access (SDMA) system. For certain aspects, an access point (AP) may receive a channel evolution feedback from one or more stations and send a request for CSI to the stations whose CSI values need to be updated. For certain aspects, the AP may poll the stations for updated CSI values. For certain aspects, deterministic back-off timers may be assigned to the stations indicating when to send their CSI feedback. The proposed methods may improve system performance.
