摘要： Transmission techniques are provided that improve service continuity and reduce interruptions in delivery of content that can be caused by transitions that occur when the User Equipment (UE) moves from one cell to the other, or when the delivery of content changes from a Point-to-Point (PTP) connection to a Point-to-Multipoint (PTM) connection in the same serving cell, and vice-versa. Such transmission techniques enable seamless delivery of content across cell borders and/or between different transmission schemes such as Point-to-Multipoint (PTM) and Point-to-Point (PTP). Mechanisms for adjusting different streams and for recovering content from each data block during such transitions are also provided so that data is not lost during a transition. In addition, mechanisms for realigning data during decoding at a receiving terminal are also provided.
摘要翻译：提供了传输技术，其提高服务连续性并减少当用户设备（UE）从一个小区移动到另一个小区时发生的转换可能导致的内容传递中断，或者当内容的传递从点到 -Point（PTP）连接到同一服务小区中的点对多点（PTM）连接，反之亦然。这样的传输技术能够跨小区边界和/或不同传输方案（例如点对多点（PTM）和点对点（PTP））之间的无缝传递内容。还提供了用于在这种转换期间调整不同流并用于从每个数据块恢复内容的机制，使得数据在转换期间不会丢失。此外，还提供了在接收终端的解码期间重新对准数据的机制。

摘要： In a particular embodiment, a method of providing redundancy for error recovery in multi-carrier wireless communications includes transmitting a primary version of information via a first carrier, transmitting a first portion of a redundancy version of the information via a second carrier, and transmitting a second portion of the redundancy version of the information via a third carrier. The primary version is encoded using a first encoding scheme and the redundancy version is encoded using a second encoding scheme. The primary version, the first portion, and the second portion are transmitted substantially simultaneously.

摘要： Techniques for transmitting data and training sequence efficiently using new slot and block formats are described. A transmitter processes (e.g., encodes, interleaves, and partitions) a data block to obtain multiple output blocks. For each output block, the transmitter generates multiple bursts having a training sequence that is shared by these bursts. The transmitter sends the multiple bursts for each output block in multiple time slots, e.g., consecutive time slots in one frame. The multiple bursts for each output block may (1) include one or more short training sequences, (2) omit guard periods between adjacent bursts, (3) include a first tail bit field at the start of the first burst and a second tail bit field at the end of the last burst, (4) include at least one stealing flag field, or (5) have any combination of the above.

摘要： A control scheme using packet headers allows GSM EDGE Radio Access Network (GERAN) systems to increase spectral efficiency through multiplexing techniques, such as superposition coding, multi-user packet transmission, joint detection, and/or joint decoding. A fast feedback scheme for GERAN allows Voice over Internet Protocol (VoIP) frames to be transmitted over GERAN air interfaces without excessive feedback latency. As a result, Hybrid Automatic Repeat-reQuest (H-ARM) acknowledgements may be timely provided for end-to-end VoIP calls that traverse GERAN air interfaces. Additionally, Incremental Redundancy H-ARQ and link quality feedback latencies are decreased.

摘要： A method and apparatus resolves conflicts and ambiguities of GSM standards arising in DTM by monitoring only selected downlink timeslots for uplink status flags (USFs). Downlink timeslots with a packet data channel (PDCH) are monitored for a USF from a lowest numbered time slot, B(0), to a maximum time slot B(MAX) where B(MAX) is equal to the lowest transmission uplink timeslot, B(x), in the corresponding TDMA uplink frame if the second lowest transmission uplink timeslot B(x)+1, is a circuit switched timeslot and where B(MAX) is equal to the second lowest transmission timeslot in the corresponding TDMA frame, B(x)+1, otherwise.

摘要： Systems and methods that enable a network to configure its neighbor relation (e.g., automatically) by commanding each user equipment (UE) to scan its respective area for neighbor base stations on a predetermined frequency or radio access technology. Moreover, the network can compile lists (e.g., whitelists that identify base stations associated with the network, and black lists that indicate base stations associated with foreign networks) and advise the UEs accordingly (e.g., regarding possibilities for availability of base stations.) The network can therefore configure its neighbor relations automatically and with a higher precision as compared to manual configurations.

摘要： Techniques for puncturing symbols in a communications system. S symbols are received for a frame having a capacity of N symbols, with S being greater than N. P symbols need to be punctured so that remaining symbols fit into the frame. A number of puncture distances, D1 through DN, are computed based on S and P. A particular number of symbol punctures is determined for each computed puncture distance. P1 through PN symbol punctures are then performed at the distances of D1 through DN, respectively. For a more even distribution of the symbol punctures, each of the distances D1 through DN can be selected to be greater than or equal to a minimum puncture distance Dmin defined as Dmin=└S/P┘, where └ ┘ denotes a floor operator. The symbol punctures at each computed distance can be performed together or distributed with symbol punctures at other distances.
