摘要： Communication efficiency may be enhanced by using compressed headers. In an example embodiment, a method is performed by a transmitting device to reduce header size. A mapping is created between a logical channel identifier and a compressed logical channel identifier. The compressed logical channel identifier occupies fewer bits than the logical channel identifier. The mapping is transmitted to a receiving device. A compressed header that includes the compressed logical channel identifier is formulated. A communication that includes the compressed header is transmitted to the receiving device. In another example embodiment, a method is performed by a receiving device to decode a header having a reduced size. A mapping and a communication including a compressed header are received. A compressed logical channel identifier is extracted from the compressed header. A logical channel identifier is recovered from the compressed logical channel identifier using the mapping.

摘要： In compression of packet data headers the compressor side (100) in a point-to-multipoint connection transmits (301) a message announcing a particular service. The entities (200) receiving the announcement message are adapted to respond to the message and based on the response message(s) (305) the compressor can adapt the compression scheme used. In particular the compressor may compress (315) or not compress (311) the header of the packet data header.

摘要： A set of radio resources are allocated to a first user equipment (110). The radio network node (130) receives a request for radio resources from a second user equipment (120) being associated with a first or second category. Furthermore, the radio network node (130) measures an inactivity time period of the first user equipment (110). Then, the radio network node (130) releases the set of radio resources when the inactivity time period exceeds a threshold to be applied dependent on the category of the request. The releasing of the set of radio resources is triggered by the request.

摘要： Teachings presented herein provide reduced computational complexity and/or memory requirements for a mobile terminal to determine the power backoff required for a multi-carrier uplink signal. In particular, the mobile terminal determines whether its power headroom falls below a pre-defined power headroom threshold, indicating that it is headroom limited. If so, it5 quantizes power allocated to each carrier of the multi-carrier uplink signal according to a pre-defined quantization policy. In doing so, the mobile terminal thereby reduces the possible configurations that may be selected for the multi-carrier uplink signal. Thus, in one embodiment, the mobile terminal stores the required backoff in a look-up table for only the configurations that may be selected when the mobile terminal is headroom limited. This relieves10 the memory requirements of the mobile terminal as compared to storing the required backoff for all possible configurations of the multi-carrier uplink signal.
摘要翻译：本文提出的教学提供了移动终端降低的计算复杂度和/或存储器要求，以确定多载波上行链路信号所需的功率回退。特别地，移动终端确定其功率余量是否低于预定义的功率余量阈值，指示其净空限制。如果是，则它根据预定义的量化策略量化分配给多载波上行链路信号的每个载波的功率。在这样做时，移动终端因此减少了可能为多载波上行链路信号选择的可能配置。因此，在一个实施例中，移动终端仅在移动终端被限制空间时可以选择的配置在查找表中存储所需的退避。与存储针对多载波上行链路信号的所有可能配置的所需退避相比，这减轻了移动终端的存储器要求。

摘要： In one aspect, the present invention exploits the fact that the radio interface parameters used for multi-cell operation of a terminal are typically correlated. That is, in the uplink and/or downlink direction, the radio interface parameters used in the two or more cells supporting simultaneous multi-cell communication with the terminal may be related. Accordingly, in one or more embodiments presented herein, a terminal is provided one full set of parameters for the reception of data (downlink communication) and/or transmission of data (uplink communication) in one cell (the anchor serving cell), and some additional (delta) infoπnation that describes how the set of parameters for one or more other cells (the secondary serving cells) differs from the first cell. Correspondingly, the terminal is configured to derive the additional parameters needed for communicating in the one or more other cells, based on the full set of parameters and the delta information.
摘要翻译：一方面，本发明利用了用于终端的多小区操作的无线接口参数通常相关的事实。也就是说，在上行链路和/或下行链路方向上，与终端同时进行多小区通信的两个以上的小区中使用的无线接口参数可以相关。因此，在本文呈现的一个或多个实施例中，为一个小区（锚服务小区）中的数据（下行链路通信）和/或数据（上行链路通信）的接收和/或传输提供一个完整的参数集合，描述一个或多个其他单元（辅助服务小区）的参数集合如何与第一小区不同的附加（增量）信息。相应地，终端被配置为基于完整的参数集合和增量信息来导出在一个或多个其他小区中进行通信所需的附加参数。

摘要： The technology applies to a cellular radio communication system in which a mobile radio terminal transmits information in transmission time intervals (TTIs) that is received by a serving base station and by one or more non-serving base stations. A number N of hybrid automatic repeat request (HARQ) transmissions transmitted together by the mobile terminal is determined. An HARQ transmission includes a first transmission, one or more retransmissions of the first transmission, or both. An indication of the number N of HARQ transmissions is provided either directly or indirectly to the one or more non-serving base stations so that the one or more non-serving base stations can take the number N into account when combining HARQ transmissions received from the mobile terminal.
