摘要： Disclosed herein is a system and method for downlink beamforming that takes into account imperfect channel state information (CSI) at the transmitter when determining the steering vector used in the beamforming process. The steering vector is calculated to increase the ratio of the average power of a desired signal component to the sum of the interference power of other wireless terminals, referred to as the signal-to-leakage ratio. By accounting for imperfect CSI when calculating the steering vector, the bit-error rate for a given signal-to-noise ratio is decreased. Also disclosed is a power allocation method that improves performance of the system by increasing the signal-to-interference-plus-noise ratio for all of the wireless terminals currently communicating with the base station. The power allocation similarly decreases the bit-error rate for a given signal-to-noise ratio, especially at high signal-to-noise ratios.

摘要： A system of methods and constructs that enable multiple users to simultaneously share transmission (i.e., radio) resources, while reducing delay for users with delay-sensitive applications, is disclosed. The system provides for: forming one or more than one shared persistent (or “sticky”) assignment (SSA) group in a sector; allocating more than one shared sticky resource in at least one SSA group; and dividing users into at least a first class of users and a second class of users. The first class of users is given a higher priority to access the shared resources than the second class of users when the shared resources become available for a new packet. The first class of users is also given more choices of shared resources when starting transmission of a new packet.

摘要： In the system acquisition process system information is non-coherently detected using correlation of reconstructed and received preamble signals, such as the primary broadcast control channel (PBCCH) and the acquisition pilots (TDM1, TDM2, and TDM3). The phase correlation signals between the correlated signals of PBCCH and TDM2 or TDM3 and between the correlated signals of TDM2 and TDM3 are combined to decode other sector interference (OSI) information and the like. Acquisition is also made more efficient by taking advantage of predictable information based on system synchronicity. The sync/async bit is included in at least one of the acquisition pilots. The mobile then uses knowledge of system synchronicity to more efficiently detect the additional information in the superframe preamble.

摘要： Two types of access probe messages are defined: a first when a mobile station has not yet been assigned a media access code index (MAC ID), and a second when a mobile station already has a MAC ID assigned by the base stations in the active set. Base stations can differentiate between the first and second types of access probes according to the scrambling sequence used. In the second type, while different MAC IDs are used by each of the mobile stations in the sector, they are all scrambled according to a similar scrambling sequence defined specifically for these second types of access probes. The rake receivers used in such networks are configured to repeat the rake finger processing after CP removal, DFT, de-channelizing, and IDFT, thereby reducing their complexity.
