20120213181 | TRANSMIT DIVERSITY AND SPATIAL SPREADING FOR AN OFDM-BASED MULTI-ANTENNA COMMUNICATION SYSTEM - A multi-antenna transmitting entity transmits data to a single- or multi-antenna receiving entity using (1) a steered mode to direct the data transmission toward the receiving entity or (2) a pseudo-random transmit steering (PRTS) mode to randomize the effective channels observed by the data transmission across the subbands. For transmit diversity, the transmitting entity uses different pseudo-random steering vectors across the subbands but the same steering vector across a packet for each subband. The receiving entity does not need to have knowledge of the pseudo-random steering vectors or perform any special processing. For spatial spreading, the transmitting entity uses different pseudo-random steering vectors across the subbands and different steering vectors across the packet for each subband. Only the transmitting and receiving entities know the steering vectors used for data transmission. Other aspects, embodiments, and features are also claimed and disclosed. | 2012-08-23 |
20120213182 | PRIMARY SERVING GATEWAY RESOLUTION - Various embodiments relate to a system and related method for handling requests from a user device in a wireless communications network. Various embodiments relate to a Policy and Charging Rules Node (PCRN) attempting to bind an IP-CAN session established in a Packet Data Network gateway (PGW) with a gateway control session established in a serving gateway (SGW). In instances when the IP-CAN session and gateway control session no longer match, the PCRN may wait to receive a subsequent message from the PGW and/or SGW. When the PCRN does not receive the subsequent message containing a matching session, the PCRN may terminate the sessions in all the relevant gateways. This may cause the system to reestablish a new, matching connection instead of remaining in a hanging state. | 2012-08-23 |
