摘要： An object of the present invention is to provide a mechanism for controlling a repeater that is less costly and more flexible. The objective is achieved by a method in a control unit (150) for controlling a repeater (100) being comprised in a radio access network (110). The control unit sends a repeater control message to the repeater (100). The repeater control message is tunneled as ordinary data communication via an available radio communication channel (160) within the radio access network (110). The repeater control message is configured to control the repeater (100).

摘要： A radio access network comprises a donor base station node (28) and a relay base station node (29). The relay base station node (29) participates in communications across a first radio interface (Uu) 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 sobiVame 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： 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.

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： A method in a user equipment for estimating a channel upon receiving an enhanced control channel, eCCH, from a network node in a telecommunications system. The eCCH is distributed over multiple resource block pairs, wherein each of the multiple resource block pairs comprises a number of resources. Each resource is associated with a respective antenna port. The user equipment identifies an antenna port being associated with more than one resource. The more than one resource is present in different resource block pairs of the multiple resource block pairs over which the eCCH is distributed. The identifying is based on how the eCCH is mapped to the multiple resource block pairs. Also, the user equipment estimates the downlink channel for the eCCH based on the identified antenna port in the more than one resource in the multiple resource block pairs. A user equipment, a method in network node and a network node are also provided.

摘要： The invention proposes a novel method for handling acknowledgement messages between a first protocol layer (L1) and a second protocol layer (L2) in a network node operating as a relay network node (RN). The first protocol layer (L1) is lower with respect to the second protocol layer (L2). The acknowledgement messages (ACK) are related to Automatic Repeat Request (ARQ) processes and the Relay Node (RN) is engaged in an Uplink transmission towards a network access node (eNB). The method comprises a step (10) of receiving a first grant indication by said network access node (eNB) that an Uplink Transmission is granted at said first protocol layer entity (L1) and a step of sending (100) towards said second protocol layer entity (L2) an indication of Acknowledgement (ACK) after receiving a first grant indication. The invention also proposes a corresponding Relay Node (RN).
