摘要： The disclosure relates to connection setup between a wireless device and a mobile communication network using random access, and more specifically to dynamic random access resource configuration and selection. The disclosure provides for a method in a wireless device, of selecting random access resources for performing a random access procedure to a wireless network. The method comprises the step receiving information from a radio network node comprised in a cell of the wireless network, wherein the received information indicates at least a first and a second random access resource having different resource sizes. The method further comprises selecting one of said at least first and a second random access resources based on an expected uplink power received by the radio network node and transmitting a random access message to said wireless network using the selected resource. The disclosure further relates to methods for providing random access resources, as well as to a wireless device, and to radio network nodes of a wireless network.

摘要： In one aspect, the teachings herein provide a method and apparatus for extending certain HARQ feedback procedures introduced in LTE Rel-10, which were defined for CA configurations involving TDD serving cells of the same UL/DL configuration, to the new, more complex CA configurations introduced in Rel-11, which involve the aggregation of interband TDD serving cells with differing UL/DL configurations. Such reuse enables reliant and efficient HARQ feedback signaling in LTE Rel-11, without substantially increasing the specification or implementation complexity of HARQ feedback signaling in LTE Rel-11, despite the decidedly more complex CA configurations introduced in LTE Rel-11.

摘要： In a mobile network, the transmission of downlink data blocks (303, 307) to one or more terminal devices (200, 210) is accomplished on the basis of a retransmission protocol with a first feedback time (F1) defining a time interval between transmission of a first data block (303) and transmission of a first feedback message (308) being different from a second feedback time (F2) defining a time interval between transmission of a second data block (307) and transmission of a second feedback message (309). The first feedback message (308) indicates whether the first data block (303) was successfully received, and the second feedback message (309) indicates whether the second data block (307) was successfully received. A base station (100) of the mobile network controls the terminal device (200, 210) to send the second feedback message (309) on other resources than used for transmission of the first feedback message (308).

摘要： A method in a radio communication system (100) for assigning a short-lived Cell Radio Network Temporary Identifier, "C-RNTI", to a first user equipment (110) performing random access to a radio network node (130). The method comprises registering (303, 312) the first user equipment (110) as connected to the radio network node (130), wherein the short-lived C-RNTI is assigned to the first user equipment (110) for identification thereof during a first time period; and transferring (304, 313), from the radio network node (130) to the first user equipment (110), a message for synchronizing the radio network node (130) and the first user equipment (110) with respect to the first time period. Before the first time period has elapsed the method further comprises associating (302), by the radio network node (130), a first extended C-RNTI to the first user equipment (110), wherein the first extended C-RNTI comprises a first set of bits and a second set of bits, wherein number of bits of the first set is equal to number of bits of the short-lived C-RNTI. After the first time period has elapsed the method further comprises maintaining (305, 314) the first user equipment (110) connected to the radio network node (130), allowing (306) the short-lived C-RNTI to be assigned to a second user equipment (120), thereby enabling use of the short-lived C-RNTI for identification of the second user equipment (120) when connected to the radio network node (130); and assigning downlink transmission resources to the first user equipment (110) by utilizing the first extended C-RNTI as a means for identifying the first user equipment (110) on a Physical Downlink Control Channel, PDCCH.

摘要： The invention relates to a method and arrangement (500) in a network communication node (13, 14) for adapting an amount of periodic resources. The periodic resources are semi statically configured to a user equipment (11, 12) within a cell (10) of a radio telecommunications network (1). The network communication node (13,14) is comprised in the radio telecommunications network (1) and controls an amount of radio channel resources within the cell (10) of a radio control channel. The amount of periodic resources is defined as a size of a control region, which control region is at least a part of the amount of radio channel resources. The user equipment (11,12) uses a specific control signalling type on the radio control channel. The network communication node determines a traffic load in the cell (10) and obtains a periodicity requirement indication, which indication is based on the control signalling type. The network communication node then determines the size of the control region based on the determined traffic load in the cell (10) and the obtained periodicity requirement indication and thereby adapts the amount of periodic resources for the cell (10).

摘要： Method and arrangement in a network entity for supporting link adaptation in a wireless communication system. The method comprises obtaining 204 one or more predicted parameters related to the quality of a radio link. The method further comprises measuring 206 one or more actual parameters, corresponding to the one or more predicted parameters. The method further comprises deriving 208 one or more error distributions based on the difference between the predicted and actual one or more parameters, from which error distributions a link adaptation margin estimate is derived, based on a predetermined radio link quality target. The link adaptation margin estimate is then used for supporting link adaptation for the radio link.

摘要： The present invention relates to allowing configuring CSI reporting (step S-224, 310) on radio resources that are allocated over a plurality of sub frames on Physical Uplink Shared Channel (PUSCH). Allocation of said radio resources (steps S-202, 404) can be performed by semi-persistent allocation or by using Transmission Time Interval (TTI) bundling. By using either semi-persistent scheduling or TTI-bundling as decided by an eNB (104, 204, 600) the UE (102, 202, 500) can be configured to report CSI (step S-224, 310) for a plurality of UL transmissions. By allocating radio resources by using semi-persistent scheduling, the signaling overhead, which can be substantial for dynamic scheduling of radio resources, decreases. By using TTI-bundling the coverage of the CSI-reports increases.
摘要翻译：本发明涉及允许在物理上行链路共享信道（PUSCH）上通过多个子帧分配的无线电资源上配置CSI报告（步骤S-224,310）。所述无线电资源的分配（步骤S-202,404）可以通过半持久分配或使用传输时间间隔（TTI）捆绑来执行。通过使用由eNB（104,204,600）所确定的半持久调度或TTI绑定，UE（102,202,500）可以被配置为向多个服务器（102,202,600）报告CSI（步骤S-224,310） UL传输。通过使用半永久调度来分配无线电资源，对于无线电资源的动态调度可能是重要的信令开销减小。通过使用TTI捆绑，CSI报告的覆盖面增加。

摘要： Methods and apparatus are provided for mitigating cross-link interference. The method is implemented by a base station of a wireless communication system, the base station serving user terminals in a first cell. The method comprises selecting (610) a primary time division duplex, TDD, configuration designating uplink and downlink subframes for communication with the user terminals in the first cell, and determining (620) uplink subframes of the primary TDD configuration that are overlapping in time with downlink subframes of a TDD configuration used in a second cell. The method also comprises transmitting (630), to a user terminal in the first cell, a request to use a supplemental TDD configuration for transmitting uplink control information, wherein uplink subframes of the supplemental TDD configuration are not overlapping in time with downlink subframes of the TDD configuration used in the second cell.
