摘要： A method for scheduling resources for uplink transmissions in a radio access network includes each of a plurality of access points (APs) placing its resources to the disposition of other APs and transmitting a blocking signal if it does not allow other APs to use any of its resources. The method includes a user terminal (UT) listening for blocking signals and an AP scheduling the UT on the AP's own resources and/or on resources belonging to one or more other APs.

摘要： Teachings herein schedule a data transmission in a variable bandwidth wireless communication system based on the power efficiency of a mobile node. One or more processing circuits, of the mobile node or a network node, determine the value of a control setting that defines a power efficiency configuration of the mobile node. In one embodiment, for example, the power efficiency configuration indicates the mobile node is configured to operate at the maximum power efficiency attainable without the data rate of the data transmission falling below a minimum data rate required by a quality of service. Regardless, the one or more processing circuits select from different possible bandwidths of the data transmission a bandwidth that supports a given data rate and that, according to a power efficiency model that models power efficiency of the mobile node for the different possible bandwidths, yields a power efficiency comporting with the power efficiency configuration.

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： A communication device has a first transceiver that operates in a first communication system in the presence of a second transceiver that operates in a second communication system that is unrelated to the first communication system. A scheduler of packets for transmission by the first transceiver uses information about when the second communication system will be transmitting a signal that will interfere with reception by the first transceiver, and schedules data for which re-transmission is not essential in those time slots in which an implicit NACK is expected due to the second transceiver's operation.

摘要： Channel state feedback is provided from a UE to a base station as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.

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： The present invention relates to methods and a transmitter and a receiver for a mobile communication system. The basic idea of the present invention is to recursively derive from previous HARQ feedback the number of HARQ transmissions that is required to be able to decode the transmitted data successfully and to only transmit explicit HARQ feedback information if the decoding result differs from the derived result.

摘要： The present invention relates to a base station and a method in a mobile telecommunication network for allocating and de-allocating uplink base station processing resources to a mobile terminal. The base station are adapted to communicate to a mobile terminal on an uplink channel supporting macro-diversity, and the base station is adapted to be a non-serving base-station without control of the resource allocation to the mobile-terminal. The base station comprises means for predicting a likelihood of successful decoding of a future transmission, and means for allocating or de-allocating processing resources based on said prediction.

摘要： A technique is provided for processing data in a packet-based communications environment. A single data packet is encapsulated into a single link layer packet data unit. The link layer unit is encoded to form at least one code block. After the currently available radio resource capacity during a fixed duration transmission interval has been determined, bits within the code block are selected to fit into or otherwise match the radio resource capacity. Thereafter, the selected bits are transmitted via a physical layer. In some variations, unsolicited redundant sets of bits are transmitted thereafter to facilitate successful receipt.

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。
