Abstract: Embodiments herein relate to a method in a radio network node (1) for enabling a user equipment (10) to access a radio communications network. The user equipment (10) is located in an area of the radio communications network. The radio network node (1) retrieves a system signature. The system signature is indicating a set of system information to be used by the user equipment (10) to access the radio network node (1). The radio network node (1) then transmits the system signature within the area. This enables the user equipment (10) to access the radio communications network.

Abstract: The technology described automatically resolves cell identity collisions/conflicts in a cellular radio communications network. A detecting node determines that a first cell identifier associated with a first conflicting cell is the same as a second cell identifier associated with a second conflicting cell. One of the first and second conflicting cells is selected to change its cell identifier. A different cell identifier is determined for the selected cell. The different cell identifier is then provided to other cells and preferably to user equipment (UE) terminals without disrupting ongoing UE communications.

Abstract: This document proposes soft activation and inactivation of (network) repeaters that are, for example, activated on an as-needed basis. With soft activation, repeater gain ramps upward at a controlled rate, thereby avoiding rapid changes in interference caused by the repeater. Likewise, with soft inactivation, repeater gain ramps downward at a controlled rate. Soft activation/inactivation results in more gradual changes in the interference contribution of the repeater, thereby improving the performance of interference-compensating radio receivers operating in proximity to the repeater.

Abstract: Neighbor cell relation lists are initialized and managed in various ways that are especially beneficial to closed subscriber group (CSG) cells served by CSG base stations. Typically, only a radio terminal belonging to the CSG is permitted to access and receive service from the CSG cell. As a result, information is provided to radio terminals in the cells neighboring the CSG cell that generally indicates that radio terminals are not to report to a respective serving base station signal quality measurements of a signal received from the CSG base station unless the radio terminal is a member of the closed subscriber group for the CSG cell. When a CSG cell is powered-up, it is determined whether the CSG cell has previously been powered-on in the same environment. If so, the neighbor cell relation information for the CSG cell is updated with other network node(s). If not, neighbor cell relations of the CSG cell are initialized.

Abstract: The invention discloses a mobile station (200), a base station (300), a method and a computer program for communication in a wireless communication network (100), where cell edge user experiencing difficulties on the contention-based channel are treated differently than those users who are not power limited and/or do not experience collisions. Suggested solutions to this problem may be different treatment of the cell edge users in contrast to users located closer to the base station (300) either by communication over an orthogonal scheduled channel, or by forcing mobile stations (200) who have successfully sent their data to wait a specific time period or by dividing the mobile stations (200) into different groups based on the signal attenuation experienced by the different mobile stations (200).

Abstract: 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.

Abstract: Error contributions in a DMT system where a received DMT-signal is effected by intersymbol interference, intercarrier interference and additive noise are minimized. Intersymbol interference average power, intercarrier interference average power, and additive noise average power are calculated. A cost function is determined by adding the intersymbol interference average power, the intercarrier interference average power, and the additive noise average power. A constraint is introduced which avoids a trivial solution where a time domain equalizer (TEQ) vector is equal to zero. The cost function is minimized by optimizing the TEQ vector.

Abstract: Data packets are efficiently combined to fit into a transmission interval. A current communications condition, e.g., the current channel quality, is detected and used to select an appropriate combination of modulation and channel encoding parameters. However, data packets are combined and pre-encoded before the modulation and/or coding scheme (MCS) to be used in a specific transmission interval is known. Once the MCS is known for the transmission interval, an appropriate number of pre-processed data blocks are combined. Some complex packet processing operations can be performed in advance, without any knowledge of the MCS.

Abstract: A hybrid ARQ scheme is used incremental data packet combining. In an example embodiment, the hybrid ARQ scheme with incremental data packet combining employs three feedback signaling commands: ACK, NACK, and LOST. Using these three feedback commands, the hybrid ARQ scheme with incremental data packet combining provides both robustness and good performance. This scheme is particularly advantageous in communication systems with unreliable communication channels, e.g., a fading radio channel, where forward error correction (FEC) codes are used and some of the code symbols are more important than other code symbols. Benefits include increased throughput and decreased delay of the packet data communication.
