摘要： A receiver may reduce the effects of distortion when determining signal usability in the following manner. Upon receiving a signal, the receiver separates a desired component, an undesired component, and a distortion component, wherein the desired component includes the signal that was originally transmitted and the undesired component includes interference and noise. Having isolated the distortion component, it can be mitigated such that the usability of the signal received can be determined based on a ratio between the desired and undesired components.
摘要翻译：当以下列方式确定信号可用性时，接收机可以减小失真的影响。在接收到信号时，接收机分离出期望的分量，不期望的分量和失真分量，其中期望的分量包括最初传输的信号，并且不需要的分量包括干扰和噪声。在分离了失真分量之后，可以减轻所接收的信号的可用性，这样就可以基于期望的和不期望的分量之间的比率来确定。

摘要： A flexible-bandwith radio is provided. Briefly, the radio is equipped with a multiplicity of modulator and demodulator units arranged to communicate on a multiplicity of discrete frequency bands. There is no need for the individual frequency bands to be contiguous. As a result, the radio is able to simultaneously supporting a multiplicity of band-limited radio channels. The radio is further equipped with a channel combiner unit and a channel divider unit to combine the individual channels to form a high-capacity aggregate channel. The aggregate channel is then provided to the user, or to a user application. In a first embodiment, the radio utilizes a multiplicity of discrete modulator, demodulator, combiner, and divider units. In a second embodiment, the radio utilizes a suitably-programmed digital signal processor to perform the equivalent modulator, demodulator, combiner, and divider functions.

摘要： A communication system performs adaptive scheduling by considering present and past reported CQI values and other indications of channel conditions in scheduling a Modulation and Coding Scheme (MCS) and then executing a ‘dithering’ function in order to effectuate an MCS that is intermediate between adjacent discrete MCSs. In one embodiment, the communication system determines a first MCS based on a channel quality metric received from a mobile station (MS) and then transmits data utilizing the first MCS. The communication system assigns weights to each of the first MCS and a second MCS based on whether the transmitted data is acknowledged and, based on the assigned weights, selects one of the first and second MCSs for a subsequent transmission of data to the MS. The communication system also may assign weights to each of a first and second MCS based on a transition between a MIMO-A and a MIMO-B transmission scheme.

摘要： A chalk line is marked by attaching two hooks to a nail, and then extending a string a length from the nail. The hooks are attached to an apparatus that has multiple springs, such that there is a string attached to the rear of the apparatus while the hooks are attached to the front of the apparatus. When the string has been extended the desired length, the user then snaps the line to make a chalk line. Then, the pull on the string is released by the user, causing the two hooks to separate. When the two hooks separate, their connection to the nail is broken. The hooks and the apparatus associated with the hooks then is free to be reeled back to the user. The user does not have to return to the nail to remove the hooks and the associated apparatus.

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.

Then using (505) the first WLAN IP address for an application that benefits from a persistent connection. Further included is establishing (507) a second communications link between the mobile station and a second WLAN AP 111 in a second subnet (119). When the mobile station is using the application, continuing to use the first WLAN IP address for communicating with the second subnet; and requesting (517) a second WLAN IP address in the second subnet when the persistent connection is no longer needed.

摘要： A method (400, 500, 800), and apparatus (212, 230, 240) provide for mobility in WLAN voice systems. In one embodiment a processor (651) coupled to a memory (652) and a radio resource (653) determines from that client (150) should move, based for example on a signal parameter, to an adjacent MSN (240).

摘要： A mobile station establishes a schedule by which data is exchanged with an access point. The schedule allows the mobile station to use a low power mode at times outside of the scheduled service periods. However, the mobile station may occasionally need to retrieve additional data from the access point, or transmit additional data to the access point, and so initiates an unscheduled service period to do so.
摘要翻译：移动台建立与接入点交换数据的时间表。该调度允许移动台在预定的服务周期之外的时间使用低功率模式。然而，移动台可能偶尔需要从接入点检索附加数据，或者向接入点发送附加数据，因此启动非计划的服务周期来实现。

摘要： A controller (120), in response to receiving a request for a group call (201) targeting a group (101), allocates at least one power adjustment channel to the group call (202) and sends identification of the at least one power adjustment channel to at least some of the subscriber units in the group (203). Using the at least one power adjustment channel, the controller also sends unique power adjustment information to each of the at least some subscriber units (204). Unique power adjustment channel access information is also sent to the subscriber units so that each subscriber unit can receive its own unique power adjustment information (503) and adjust its inbound transmission power (504) in response. In this manner, efficient reverse power control is provided for multiple subscriber units thereby facilitating group calls in CDMA systems.
