摘要： In a wireless communication system, data is encoded by packet indifferent (PI) coding and some packets are transmitted omnidirectionally while supplemental packets are transmitted directionally to a user with a poor air link. PI encoding is defined herein as encoding in which the source data can be recovered from any K of the encoded packets, regardless of which of the encoded packets are received, where K=N+A. N is equal to the number of packets in the source data and A is the number of additional packets required due to the PI encoding. A subset of M data packets can be sent to one or many users from an omnidirectional antenna, where M is greater than or equal to K. If less than K data packets are received by at least one user, then the data block is not successfully received by that user. A number R of supplemental packets can be sent to users that did not receive K data packets successfully. The supplemental packets can be sent by a directional antenna to the specific user or users that did not receive K data packets.

摘要： A multi-mode receiver and methods are provided, which use blind source separation (BSS) analysis to distinguish the various wireless communication signals from each other. Specifically, different signal types can be identified by BSS. The different signal types can be in overlapping frequencies or they can be in completely different frequencies. The BSS analysis may use center or carrier frequency, bandwidth, modulation scheme, access scheme, or wireless communication resources as an input to assist in the BSS.

摘要： An antenna system comprises a receive diversity antenna system and a configurable antenna arrangement. Incoming signals are received through the receive diversity antenna system and outgoing signals are transmitted through the configurable antenna arrangement.

摘要： To improve WWAN coverage, an access node broadcasts overhead messages on a first channel covering a first channel environment and a second channel covering a second channel environment within a coverage region. The overhead messages carry network overhead parameters for allowing wireless mobile devices to acquire and maintain traffic channels within the cellular system. The overhead message channels are configured so that a user perceives uninterrupted wireless services while moving through different channel environments in the coverage region. In one embodiment, the overhead message channels are separate physical channels configured with different broadcast parameters to provide coverage in different environments. In another embodiment, the overhead parameter information is segregated into base and extended components that are encoded and layer modulated onto separate logical channels. Using layered modulation, wireless mobile devices can receive base components in poor coverage regions. The base components include overhead parameters for acquiring a WWAN channel.

摘要： A common group cell identifier is transmitted by adjacent base stations. Handover processing is minimized for mobile relays traveling along a predetermined path that traverses the adjacent base stations. A first base station along the path transmits a group cell identifier and a first single cell identifier within a first service area. An adjacent base station transmits the group cell identifier and a second single cell identifier within a second service area that at least partially overlaps the first service area. The mobile relay monitors the group cell identifier in certain situations and only performs a handover when the group cell identifier changes. As a result, no handovers are initiated as the mobile relay travels down the path since the group cell identifier transmitted by the base stations along the path are the same.
摘要翻译：公共组小区标识符由相邻基站发送。对于沿着穿过相邻基站的预定路径行进的移动中继站，切换处理被最小化。沿着路径的第一基站在第一服务区域内发送组小区标识符和第一单个小区标识符。相邻基站在与第一服务区域至少部分重叠的第二服务区域内发送组小区标识符和第二单个小区标识符。移动中继在某些情况下监视组信元标识符，并且仅当组信元标识符改变时执行切换。结果是，由于基站沿着路径发送的组小区标识符相同，因此随着移动中继站沿着路径的向下移动，不会切换切换。
