Abstract: PROBLEM TO BE SOLVED: To achieve transmit diversity for a legacy single-antenna receiving device.
SOLUTION: 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. 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.

Abstract: PROBLEM TO BE SOLVED: To provide techniques to partition and allocate the available system resources among cells in a communication system, and to allocate resources in each cell to the terminals for data transmission via the uplink.
SOLUTION: In one aspect, adaptive reuse schemes are provided wherein the available system resources may be dynamically and/or adaptively partitioned and allocated to the cells based on a number of factors such as the observed interference levels, loading conditions, system requirements, and so on. A reuse plan is initially defined and may be redefined, to reflect changes in the system. In another aspect, the system resources may be partitioned, such that each cell is allocated a set of channels having different performance levels. In yet another aspect, terminals in each cell are scheduled for data transmission (e.g., based on their priority or the load requirements) and assigned channels, based on their tolerance to interference and the performance of the channel.

Abstract: PROBLEM TO BE SOLVED: To provide various techniques for performing sphere detection to recover data symbols sent in a MIMO transmission.SOLUTION: In an aspect, sphere detection is performed for data symbols generated with at least two modulation schemes. In another aspect, sphere detection is performed for the data symbols in an order based on at least one attribute of the data symbols such as error probabilities of the data symbols, modulation schemes used for the data symbols, and link margins for the data symbols. In yet another aspect, rates for multiple data streams detected with sphere detection are selected based on channel state information. The channel state information includes a channel estimate, a noise estimate, an interference estimate, a power measurement, and a signal quality estimate. After signal qualities of the data streams are estimated based on an upper triangular matrix used for sphere detection and/or an assumption that interference from data streams already detected is canceled, the rates for the data streams are selected based on the estimated signal qualities.

Abstract: PROBLEM TO BE SOLVED: To provide a receiver for a wireless communication network with an extended range.SOLUTION: Techniques for detecting and demodulating a signal/transmission are described. Signal detection is performed in multiple stages using different types of signal processing, e.g., using time-domain correlation for a first stage, frequency-domain processing for a second stage, and time-domain processing for a third stage. For the first stage, products of symbols are generated for at least two different delays, correlation between the products for each delay and known values is performed, and correlation results for all delays are combined and used to declare the presence of a signal. For demodulation, the timing of input samples is adjusted to obtain timing-adjusted samples. A frequency offset is estimated and removed from the timing-adjusted samples to obtain frequency-corrected samples, which are processed with a channel estimate to obtain detected symbols.
