Patent number: 8340207Abstract: A first N×M codebook of a first rank M may be used to generate a second N×(N?M) codebook of a second rank (N?M). This second codebook is both orthogonal and complementary to the first codebook. In practice, this may reduce storage requirements in closed-loop MIMO beamforming, because the second codebook may be dynamically generated as needed by a base station and/or a mobile station. In some cases, a higher rank beamforming matrix or precoding matrix may be formed from a lower rank (e.g., one or two) beamforming matrix or precoding matrix. Also, a novel way to generate the rotation matrix Qv(t-1) is disclosed.Type: GrantFiled: April 29, 2010Date of Patent: December 25, 2012Assignee: Intel CorporationInventors: Qinghua Li, Xintian Eddie Lin, Yuan Zhu

Patent number: 8099119Abstract: A method providing channel quality indicator (CQI) feedback from subscriber stations (SSs) to a base station (BS) may include a combination of a thresholding scheme and a best-M scheme. Another method providing CQI feedback may include providing multiple feedback channels, with SSs randomly allocating CQI values among the multiple feedback channels. The BS may choose a prevailing CQI message when channel contention occurs. Another method of providing CQI feedback may include SSs transmitting to the BS numbers of their CQI values that exceed a CQI threshold. Based on these numbers, the BS may determine how many CQI values each SS may send, and on which channels. The SSs may send these CQI values according to instructions from the BS.Type: GrantFiled: August 6, 2008Date of Patent: January 17, 2012Assignee: Intel CorporationInventors: Xiaoxin Wu, Guangjie Li

Patent number: 7916670Abstract: An apparatus and method for block acknowledgements with reduced recipient state information are described. In one embodiment, the method comprises the storing of a receive state for a block of frames received during a transmission opportunity (TXOP) with an on-chip state memory. Once stored, an immediate block acknowledgement, including the receive state information, may be transmitted to an originator according to a block acknowledgement request (BAR) received during the TXOP. In the embodiments described, the BAR is received during the TXOP in which the block of data frames were transmitted to a recipient. In one embodiment, the recipient is free to discard the receive state information to free space within the on-chip system memory by requiring the originator to maintain the receive state information of blocks of data frames transmitted during TXOPs. Other embodiments are described and claimed.Type: GrantFiled: April 27, 2009Date of Patent: March 29, 2011Assignee: Intel CorporationInventors: Solomon Trainin, Robert J. Stacey

Patent number: 7529548Abstract: Adapting a wireless communications link between a transmitter and a receiver involves reducing the RF bandwidth of an uplink communications channel to achieve a desired channel quality. The RF bandwidth of the uplink communications channel is reduced when the desired channel quality is not achieved using the entire available RF bandwidth for uplink communications. Reducing the RF bandwidth of an uplink channel enables the uplink limit of a subscriber unit to be extended beyond what is possible when the entire available RF bandwidth is used for uplink communications. Additional uplink time slots can be allocated to the uplink communications channel with the reduced RF band so that a constant overall transmission rate can be maintained between the transmitter and the receiver.Type: GrantFiled: June 28, 2001Date of Patent: May 5, 2009Assignee: Intel CorporationInventor: Peroor K. Sebastian
