摘要： At a mobile device, a total received power represents signals received from all access points. In order to calculate an appropriate transmit power for communication with a single access point, a mobile device determines a per sector received power level. The mobile device can ascertain a time-domain channel response from each access point pilot signal, ascertain a received digital power lever per sector from each access point pilot signal and, based in part on the digital power level, calculate a received power level from each access point. A per sector received power level can be utilized to conserve battery power and/or to reduce interference in a wireless communications network.

摘要： Techniques to enhance the performance in a wireless communication system using segments called subbands and using precoding are shown. According to one aspect, the bandwidth for transmission to an access terminal is constrained to a preferred bandwidth which is less than the bandwidth available for transmission to an access terminal and precoding information related to the subcarriers within the constrained bandwidth is provided to a transmitter. The precoding information related to the subcarriers within a constrained bandwidth provides feedback about the forward link channel properties relative to different subbands and may be fed back on a channel associated with the bandwidth.

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： Methods and apparatuses for decoding codewords received over a MIMO channel are provided. According to one aspect of the disclosure, a cost function is computed for each constellation point of an Mth rank or spatial layer, and Ncand of those constellation points having minimum cost are preserved as candidate points, where Ncand is a parameter specified to the decoding algorithm. In addition, a cost function may be computed for all possible transitions from the Ncand candidate points of the Mth rank to all possible constellation points of the (M-1)th spatial layer, and Ncand of those transitions having minimum cost are preserved as candidate points. The process is repeated for all spatial layers, resulting in the identification of Ncand candidate codewords and their associated cost functions.

摘要： The scheduler in a base station needs CQI information from a terminal for all reuse sets every 5 ms. to decide on which re-use set to schedule a given terminal. For MIMO users, the problem is that the CQI cannot be reconstructed for all re-use sets, using the current design. Solution: (1) For Multiple Code Word MIMO users, a MIMO VCQI connection layer message enables the base station to reconstruct the MIMO-CQI for all reuse sets on a packet-by-packet basis. This will enable dynamic scheduling (RESTRICTIVE REUSE) gains. (2) For Single Code Word users, dynamic RESTRICTIVE REUSE can be obtained by changing the CQI reporting format, and also sending a MIMO-VCQI connection layer message. (3) For Single Code Word design, quasi-static scheduling gains can be obtained by sending a MIMO-VCQI connection layer message.
