摘要： A radio base station, a relay node and a respective method therein are provided for communicating data to a user equipment, the relay node being associated with the base station, wherein a downlink transmission to the user equipment is scheduled on subframe(s) available for the base station. The method in the radio base station comprises detecting that at least a part of the available subframes are not needed for downlink transmission to the relay node; and un-reserving at least one of the not needed subframes. The method further comprises transmitting, to the relay node, a release notification message notifying the relay node of the unreserved subframes for enabling the relay node to use the unreserved subframes for downlink transmission.

摘要： A method (200) for data transmission from a sender (110) to a receiver (120), wherein the data transmission is performed in predefined time intervals by associated transmission processes. The sender (110) is adapted to perform a subsequent transmission for the associated process in a time interval after one round trip time (502). Specific transmissions are performed among the transmissions, wherein the specific transmissions are limited to a subset of the time intervals, the subset being smaller than the number of all time intervals in a round trip time (502). The method (200) comprises the steps of determining (230) a maximum number of specific transmissions within a round trip time (502), specifying (240) a number of associated processes for the specific transmissions, wherein the specified number is the maximum number, and associating (250) the processes for the specific transmissions with the specific transmissions.

摘要： A radio access network comprises a donor base station node (29) and a relay base station node (20). The relay base station node (29) participates in communications across a first radio interface with a wireless terminal (30) and also participates in communications over a backhaul link across a second radio interface, the second radio interface reusing at least some functionality of the first interface. The donor base station node (28) configures a subframe configuration pattern. The subframe configuration pattern is arranged to specify which subframe(s) of a frame structure may be utilized for the backhaul link. As a result of subframe configuration, a HARQ process state in a HARQ process at one of the base station nodes is known by the other base station node by any of several operational modes.

摘要： In downlink signal communication to a mobile terminal (200), the mobile terminal (200) is associated with a serving access node (100-1). Signal communication to a further mobile terminal (200; 200′″) may interfere with the signal communication between the serving access node (100-1) and the mobile terminal (200). In order to allow interference mitigation at the mobile terminal (200), the serving access node (100-1) obtains scheduling information pertaining to the signal communication to the further mobile terminal (200; 200′″). The obtained scheduling information is then forwarded to the mobile terminal (200) to be used for interference mitigation.

摘要： Network-wide inter-cell interference is reduced by aggregating cells (herein, sub-cells) into Coordinated MultiPoint (CoMP) cells, each having a controller. The CoMP cells are divided into sets, similar to a frequency reuse plan. Scheduling information regarding transmissions scheduled to and from UEs in one set of CoMP cells is transmitted to controllers in sets of neighboring CoMP cells, in advance of the transmissions. Controllers in the receiving sets of CoMP cells schedule transmission to minimize both inter-sub-cell interference and interference with the set of CoMP cells that transmitted the scheduling information, and assuming no interference from other CoMP cells. They then transmit scheduling information to subsequent set(s) of CoMP cells. The order of scheduling information transmission between sets of CoMP cells may be rotated for fairness. The scheduling information may range from bare threshold data indicating at least one transmission, to detailed information such as estimated path gains to each UE.
摘要翻译： 通过将小区（这里是子小区）聚合到协调多点（CoMP）小区中，每个小区具有控制器来减少网络范围的小区间干扰。 CoMP单元被分为几组，类似于频率复用计划。 关于在一组CoMP小区中调度到UE的传输的调度信息在传输之前被传送到相邻CoMP小区的集合中的控制器。 CoMP小区的接收组中的控制器调度传输以最小化发送调度信息的CoMP小区集合的子小区间干扰和干扰，并且不考虑来自其他CoMP小区的干扰。 然后，它们将调度信息发送到后续的CoMP单元组。 可以旋转CoMP单元组之间的调度信息传输的顺序以获得公平性。 调度信息可以从指示至少一个传输的裸阈值数据到诸如到每个UE的估计路径增益的详细信息。

摘要： A method in a user equipment device for estimating a channel upon receiving an enhanced control channel (eCCH) from a network node in a telecommunications system includes distributing the eCCH over multiple resource pairs, where each of the multiple resource block pairs includes a number of resources. Each of the resources is associated with a respective antenna port. The user equipment device identifies an antenna port that is associated with multiple ones of the resources. The multiple ones of the resources are present in different resource block pairs of the multiple resource block pairs over which the eCCH is distributed. Identifying the antenna port is based on how the eCCH is mapped to the multiple resource block pairs. The user equipment device estimates the downlink channel for the eCCH based on the identified antenna port in the multiple ones of the resources in the multiple resource block pairs.

摘要： A method of data transmission with a first mobile station (UE1) in a cellular communication system is described. The cellular communication system comprises a plurality of access nodes (BS1, BS2, BS3), and a plurality of mobile stations (UE11, UE2′, UE3′) in a coverage area (302) of the plurality of access nodes (BS1, BS2, BS3). The plurality of access nodes (BS1, BS2, BS3) and the plurality of mobile stations are adapted to perform data transmission in a first mode between an individual access node from the plurality of access nodes and the first mobile station (UE1), and in a second mode of cooperative data transmission between at least two of the access nodes from the plurality of access nodes and the first mobile station (UE1). The method comprises the steps of identifying the first mobile station (UE1) from the plurality of mobile stations, determining an indication of a modification of the transmission conditions between the first mode and the second mode for said first mobile station (UE1), selecting the mode of data transmission for the identified mobile station from the first and the second mode based on the indication, and performing the data transmission in the selected mode. A corresponding device and program is also described.

摘要： The present invention relates to a transmission of information in a wireless communication network between a radio access node (30) and a relay node (20), wherein, according to a new ground rule, for each allocated downlink subframe for a down link transmission from the access node to the relay node, an uplink transmission subframe for an uplink transmission is allocated four transmission time intervals later. A downlink subframe is only allocated when a further subframe of the same transmission time interval for a transmission from the relay node to the user equipment is a subframe of a type that indicates to a user equipment (10) that no data are received beyond a control region of the subframe.
