摘要： Transmit power control methods and apparatus are disclosed. In several embodiments, a mobile terminal (200) is configured to effectively ignore ‘UP’ transmit power control commands in the event that the mobile terminal (200) is operating in a power-limited state. In an exemplary method for controlling transmit power at a mobile terminal (200), a plurality of transmit power control commands are received. An accumulated power control value is adjusted (350) in response to each transmit power control command that directs a negative adjustment in transmit power. However, the accumulated power control value is adjusted (350) in response to a transmit power control command that directs a positive adjustment in transmit power only if the mobile terminal (200) is not in a power-limited state. Transmit power settings for each transmission are calculated (360) based on the accumulated power control value and the one or more radio link parameters.

摘要： The present invention relates to methods and arrangements for improving the capabilities of an evolved Universal Terrestrial Radio Access Network, in particular for cases when more than one radio access network applying a time-division duplex transmission mode need to co-exist on a same carrier. The invention addresses further problems concerning an efficient allocation of uplink resources and resource allocation in a handover situation. The present invention assigns an attribute in form of a distinguishing value to the time slots used for the uplink and downlink transmission on said carrier such as to avoid scheduling of transmissions via a first radio access network in downlink or uplink time slots assigned to the second radio access network and to avoid scheduling of transmissions via the second radio access network in uplink time slots assigned for transmissions in the first radio access network.

摘要： Different frequency reuse values are associated with different channels, e.g., different types of channels in a cellular communications system. For a high speed downlink shared type of channel, the frequency reuse may be greater than one in order to achieve higher data rates. On the other hand, the frequency reuse may be set to one for other channel types, e.g., dedicated channels including both uplink and downlink dedicated channels. Alternatively, the frequency reuse may also be set greater than one for channels in addition to the downlink shared channel, e.g., one or more dedicated downlink channels, while a frequency reuse of one is deployed for one or more uplink dedicated channels. Using different frequency reuse values reduces inter-cell interference, particularly at cell borders, while still maintaining existing soft handover schemes for dedicated channels if one or more of the channels is a code division multiple access (CDMA) type of channel.
摘要翻译： 不同的频率重用值与不同的信道相关联，例如蜂窝通信系统中不同类型的信道。 对于高速下行链路共享类型的信道，频率重用可以大于1，以便实现更高的数据速率。 另一方面，对于其他信道类型，例如，包括上行链路和下行链路专用信道两者的专用信道，频率重用可以被设置为一个。 或者，除了下行链路共享信道（例如，一个或多个专用下行链路信道）之外，还可以将频率重用设置为大于一个，同时针对一个或多个上行链路专用信道部署一个频率重用。 如果一个或多个信道是码分多址（CDMA）类型的信道，则使用不同的频率重用值减少小区间干扰，特别是在小区边界，同时仍然维持用于专用信道的现有软切换方案。

摘要： The teachings presented herein propose a separation between the configuration of a sounding signal, and the initialization of the sounding signal. In other words, in at least one example embodiment proposed herein, a base station or other controlling entity separates the selection of sounding signal parameters (sounding signal configuration) and the signaling of that configuration information to a mobile terminal from the Ordering” or other initiation of sounding signal transmission. Thus, a mobile station may be sent sounding signal configuration information and subsequently be commanded (implicitly or explicitly) to begin sounding signal transmissions according to the previously provided configuration information.

摘要： A high-power point (110) and one or more low-power points (120) transmit signals associated with the same cell-identifier in a heterogeneous cell deployment. Coverage areas corresponding to the low-power points (120) fall at least partly within the coverage area for the high-power point, so that mobile stations (130) within range of a low-power point are also within range of the high-power point (110). A low-power point (120) measures timing or frequency, or both, of one or more signals received at the low-power point (120) from the high-power point (110), and adjusts the timing or frequency, or both, of a transmission from the low-power point (120) to a mobile station (130), to align the transmission with signals received by the mobile station (130) from the high-power point (110).

摘要： The present invention provides a method, a radio base station (40) and a mobile terminal (50) for allocating resources in a telecommunications network, where communications between the radio base station (40) and the mobile terminal (50) take place over a plurality of carriers. The method comprises transmitting and receiving a resource allocation message comprising one or more bits. Each of the bits corresponds to a number of resource blocks, where the number is determined from the ratio of the aggregate bandwidth of the plurality of carriers divided by the bandwidth of the carrier over which the resource allocation message is sent.

摘要： The technology described in this case facilitates random access by a user terminal with a radio base station. A user terminal determines one of a first type of uplink scrambling sequences and generates a random access message using the determined one of the first type of uplink scrambling sequences. The random access message is transmitted to the base station. The user terminal receives from the base station a second, different type of uplink scrambling sequence and uses it for subsequent communication with the radio base station. For example, the first uplink scrambling sequences may be specifically associated with the radio base station's cell area or a random access radio channel associated with the radio base station, but they are not specifically assigned to any user terminal, and the second uplink scrambling sequence may be selected from a second set of uplink scrambling sequences specifically assignable to individual user terminals.
