Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for increasing spectrum use efficiency in a mesh network.SOLUTION: Mesh Network Access Points (APs) are deployed over a geographic area. The APs monitor the communication channel for other carriers and transmit signals accordingly. The APs selectively co-transmit signals when other carriers are sensed, if the efficiency of the mesh network improves. APs select a transmission rate based on observed carrier-to-interference ratios. APs use directional antennas to increase carrier-to-interference ratios and spectral efficiency. AP transmission schedules are adaptable and adjusted according to observed carrier-to-interference measurements.

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for increasing spectrum usage frequency in a mesh network.SOLUTION: Mesh Network Access Points (APs) include gateways and routers.

Abstract: PROBLEM TO BE SOLVED: To achieve transmission diversity on a legacy single-antenna receiving device. SOLUTION: In order to obtain transmission diversity, a transmission entity uses different pseudo-random steering vectors across subbands, and uses the same steering vector across packets for each subband. A receiving entity does not need to know the pseudo-random steering vectors and further does not need to perform any space processing. For space spreading, the transmission entity uses different pseudo-random steering vectors across the subbands and uses different steering vectors across the packets for each subband. Only the transmission and the receiving entities know the steering vectors used for data transmission. COPYRIGHT: (C)2010,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a receiver structure for spatial spreading with space-time or space-frequency transmit diversity.SOLUTION: A receiving entity 150 obtains received symbols for data transmission, which has at least one data symbol stream sent with space-time transmit diversity (STTD). The receiving entity derives an overall channel response matrix in accordance with an STTD encoding scheme used for the data transmission, derives a spatial filter matrix based on the overall channel response matrix, and performs spatial matched filtering on a vector of the received symbols for each 2-symbol interval to obtain a vector of detected symbols for the 2-symbol interval. The receiving entity may perform post-processing (e.g., conjugation) on the detected symbols if needed. Alternatively, the receiving entity derives the spatial filter matrix based on an effective channel response matrix, performs the spatial matched filtering on the received symbols for each symbol period to obtain detected symbols.
