摘要： A method, system and communication network for transmitting information signals via uplink (UL) collaborative SDMA, in a wireless communication system. Base station receiver estimates a channel gain associated with the transmission path(s) of each user and keeps a matrix of normalized covariance, between users. Based on the estimated channel gain and the normalized covariance, ULS utility is able to compute channel capacity. Based on capacity estimates of (1) the multiplexed user signals and (2) the individual user signals, signals are either multiplexed for UL SDMA or are transmitted individually. An optimal selection of multiplexed signals may be based upon: (1) a cross user interface measurement; and (2) a selection mechanism based on eigen-decomposition techniques. The ULS utility enables a UL scheduler to pair information signals with clear spatial distinction and minimal correlation, based on capacity evaluations.

摘要： A method, a system and a receiver device provide timing and frequency correction in a spatial division multiple access (SDMA) system. A timing and frequency correction (TFC) logic/utility obtains a timing error estimate by using pilot symbols on a slot of six tiles. The TFC logic estimates the timing error based on pilot phase differences between unique pairs of tiles when the frequency separation of the tiles is less than a threshold value. When none of the unique pairs of tiles satisfies the threshold value, the TFC logic estimates timing error based on an exhaustive search for each candidate phase error value. The TFC logic performs timing error correction via a timing error estimate based on pilots from the symbols received on each antenna. The TFC logic performs inexplicit frequency error correction according to phase differences based on relative symbol indices.

摘要： A communication method can inform a WLAN-to-WAN handoff process as a function, at least in part, of a determined likely future quality of service (35). In particular, a comparison (36) can be made as between the likely future quality of service being afforded by the WLAN and one or more threshold values that represent acceptable levels of service. In one embodiment projected likely quality of service values as correspond to different future points in time can be used to more completely inform the evaluation process.

摘要： To address the need for an apparatus and method for CDMA-dispatch soft handoff, the present invention provides soft handoff to mobile stations (MSs) (120–123) in a dispatch call by sharing soft handoff information with all the MSs in the call at a base site (111). When a first MS (e.g., 120) needs to soft handoff, the identity of a soft handoff channel (135) at an adjacent base site (112) is shared with all the MSs. Thus, subsequent MSs (e.g. 122) that need to soft handoff to that adjacent base site may do so without requesting a soft handoff.

摘要： To address the need for an apparatus and method for CDMA-dispatch soft handoff, the present invention enables mobile-initiated soft handoff for dispatch calls. A mobile station (120) in a dispatch call establishes an individual inbound link (137) with the serving base site (111). When the mobile station determines that a handoff with an adjacent site (112) is needed, the mobile station uses its individual inbound link to request a soft handoff with the adjacent base site. After notifying the adjacent base site, the serving base site then transmits the handoff information to the mobile station to enable the mobile station to begin a soft handoff with the adjacent site.

摘要： In a resource allocator (106), a reserved resource group comprising at least one communication resource is maintained for use in supporting non-queued services. When a request for the at least one non-queued service is received, a communication resource from the reserved resource group is allocated to the request (305). When the reserved resource group becomes depleted, at least one more communication resource is assigned to the reserved resource group with greater preference relative to allocation of communication resources to requests for at least one queued service (307). In a preferred embodiment, a communication resource is assigned to the reserved resource group prior to allocating resources to any queued service requests. Additionally, communication resources (200) having varying grades of service can be accommodated.

摘要： A receiver that receives a stream of information symbols may detect the usability of the stream of information symbols received as follows. Upon receiving the stream of information symbols, the receiver separates the stream of information symbols into a desired portion and an undesired portion wherein the desired portion is the originally transmitted stream of information symbols and the undesired portion is interference and noise. From the undesired portion and the desired portion, the usability can be determined based on a ratio of the two portions.
