摘要： A method and apparatus for increasing the capacity of a system that use four transmit antennas and that employs conventional channel coding by performing space-time coding in a particular way. Each of two pairs of symbol sub-streams is space-time coded to form a respective pair of transmit-sequence chains, where at least one of the formed pairs of the transmit-sequence chains is a function of symbols of the respective symbol-sub-stream pair and not a function of the symbols of the other symbol-sub-stream pair. Four transmit sequences—two transmit sequences from each of the two pairs of symbol sub-streams—may be viewed as forming a transmission matrices B or B′ arranged as follows: ⁢ T 1 ⁢ ⁢ T 2 ⁢ ⁢ T 3 ⁢ ⁢ T 4 Antenna 105 - 1 Antenna 105 - 2 Antenna 105 - 3 Antenna 105 - 4 ⁡ [ b 1 b 1 - b 2 * - b 2 * b 2 b 2 b 1 * b 1 * b 3 - b 3 - b 4 * b 4 * b 4 - b 4 b 3 * - b 3 * ] ⁢ ⁢ or , ⁢ ⁢ T 1 ⁢ ⁢ T 2 ⁢ ⁢ T 3 ⁢ ⁢ T 4 Antenna 105 - 1 Antenna 105 - 2 Antenna 105 - 3 Antenna 105 - 4 ⁡ [ b 1 - b 2 * 0 0 b 2 b 1 * 0 0 0 0 b 3 - b 4 * 0 0 b 4 b 3 * ] ⁢ , respectively, where b1, b2, b3, and b4 are the symbols derived from a respective one of four symbol sub-streams, and b*1, b*2, b*3, and b*4 are, respectively, the complex conjugate of the aforementioned symbols. The rows of the matrix represent the different antennas, while the columns represent different symbol periods.

摘要： A wireless communication network (20) includes a power management module (50) for controlling the power of transmission between a base station (38) and a mobile station (40). Bearer traffic (e.g., voice or data signals) are transmitted using a first transmission power limit. Handoff messages are transmitted using a second, higher transmission power limit. In one example, the power management module (50) selects an increment to the first transmission power limit for purposes of transmitting handoff signals.

摘要： A wireless communication network (20) utilizes a hard handoff procedure for switching between cells serving a mobile station (40). In a disclosed example, the existing link between the mobile station (40) and a serving base station (38) is not released until a new link between a target base station (32) and a mobile station (40) is established. At the same time, however, the mobile station maintains only one base station or link within its active set at all times. The disclosed example is useful for dedicated channel and shared channel communications in CDMA systems, for example.
摘要翻译：无线通信网络（20）利用硬切换过程来在服务于移动台（40）的小区之间切换。在公开的示例中，在建立目标基站（32）和移动站（40）之间的新链路之前，不释放移动台（40）与服务基站（38）之间的现有链路。然而，同时，移动台始终在其活动集内仅维护一个基站或链路。例如，所公开的示例对于CDMA系统中的专用信道和共享信道通信是有用的。

摘要： A method for controlling a communications session with a mobile device in a wireless communications system comprised of a plurality of base stations is provided. The method comprises selecting a plurality of base stations, where at least a portion of the base stations are adapted to operate as a secondary agent, and wherein the secondary agent is capable of communicating with a mobile device. Substantially similar control information regarding the communications session is maintained in a plurality of the secondary agents. A first one of the secondary agents is selected as a first serving secondary agent to communicate with the mobile device. The first serving secondary agent uses the control information during the communications session with the mobile device. In this manner, each of the secondary agents is capable of quickly and efficiently taking over the role of communicating with the mobile device.

摘要： A two layered segmentation technique coupled with a two layer error detection technique is used to implement the wired to wireless network interface. A wireless network divides network layer packets from a wired network into radio data link packets, and the information within the radio data link packets is divided into portions that can be placed into time slots. Error detection is performed on each of the time slots and also at the radio data link packet level to determine if there is an error within the radio data link packet. Errors detected in any radio data link packet only requires retransmission of the radio data link packet in which the error was detected, and, advantageously, do not require retransmission of the entire network layer packet as would have been required in a system that mapped directly from network layer packets to time slots. Further advantageously, the system is able to be employed by systems that utilize dynamic constellation mapping schemes which result in different time slots for the same user being mapped with different constellations, and so they have different bit to symbol ratios. This is because such changes in the constellation mapping scheme are handled at the time slot level, and are not seen at the radio data link packet level. The segmentation of the network layer packets into radio link packets is independent of the number and size of the time slots which will carry the radio link packets.
摘要翻译：使用与分层错误检测技术相结合的两层分割技术来实现有线到无线网络接口。无线网络将网络层分组从有线网络划分为无线数据链路分组，无线电数据链路分组内的信息被划分为可以放置在时隙中的部分。对每个时隙以及无线电数据链路分组级别执行错误检测，以确定无线电数据链路分组内是否存在错误。在任何无线电数据链路分组中检测到的错误仅需要重传其中检测到错误的无线电数据链路分组，并且有利地，不需要如在直接映射的系统中所需的整个网络层分组的重传网络层数据包到时隙。进一步有利的是，该系统能够被利用动态星座映射方案的系统采用，这导致相同用户被映射成不同星座的不同时隙，因此它们具有不同的比特符号比率。这是因为在时隙级别处理星座映射方案中的这种改变，并且在无线电数据链路分组级别处不被看到。将网络层分组分割成无线链路分组与携带无线链路分组的时隙的数量和大小无关。

摘要： This disclosure generally discloses an anchor mobility mechanism. The anchor mobility mechanism is configured to support migration of flows between mobility anchors within a wireless communication system. The anchor mobility mechanism may be configured to support migration of flows between mobility anchors within a wireless communication system in a highly seamless manner. The anchor mobility mechanism may be configured to support migration of a flow of a wireless device between mobility anchors within a wireless communication system using functions performed by a control element (CE) and one or more forwarding elements (FEs) within the data plane of the flow of the wireless device. The functions may include identifying a time at which to initiate migration of the flow, initiating migration of the flow based on identification of the time at which to initiate migration of the flow, or the like, as well as various combinations thereof.
