摘要： The technology described in this case facilitates random access by a user terminal with a radio base station. A user terminal determines one of a first type of uplink scrambling sequences and generates a random access message using the determined one of the first type of uplink scrambling sequences. The random access message is transmitted to the base station. The user terminal receives from the base station a second, different type of uplink scrambling sequence and uses it for subsequent communication with the radio base station. For example, the first uplink scrambling sequences may be specifically associated with the radio base station's cell area or a random access radio channel associated with the radio base station, but they are not specifically assigned to any user terminal, and the second uplink scrambling sequence may be selected from a second set of uplink scrambling sequences specifically assignable to individual user terminals.

摘要： A method, network node, and base station for communicating with mobile user terminals over an air interface. A scheduler allocates and de-allocates resources in the node or base station for communicating with a user terminal. The scheduler includes a delayer for delaying the de-allocation of an allocated resource if delayed de-allocation is needed.

摘要： The present invention relates to a method and devices for determining the position of a user equipment in a mobile radio communications system. According to the invention, the position is determined via a distortion in a radio signal transmitted to or from the user equipment, wherein the distortion is caused by a scatterer being positioned at a particular location and having time-dependent scattering properties such that the scattering of a radio signal gives rise to a distortion by which said scattering properties may be identified.

摘要： A network unit of an own cell is operated in a radio communication system utilizing a radio interface that includes a radio frame made up of a number of sub-frames. The own cell serves one or more user equipments. Operation includes obtaining information about a scheduling of MBSFN data transmissions in one or more neighboring cells. The information thereby obtained is used to generate an information signal that, for a given sub-frame, enables the one or more user equipments to determine whether neighboring cell measurements can be performed using a unicast group of Orthogonal Frequency Division Multiple access (OFDM) symbols. The information signal is transmitted to the one or more user equipments, which can then use the information to determine how to locate cell-specific reference symbols when doing measurements of neighboring cells.

摘要： A radio access network (11) facilitates transmission of a Multimedia Broadcast/Multicast Service to plural user equipment units served by a radio base station. A radio network controller node (26) includes in a first message (70) of a Common Transport Channel Setup procedure an indication that sharing of a common transport bearer (60) involved in a session of the Multimedia Broadcast/Multicast Service is allowed. A radio base station (28) makes a determination whether to share the common transport bearer (60) among user equipment units (30) situated in plural cells (C) served by the radio base station (28). If the determination is positive, the radio base station (28) includes in a second message (80) of the Common Transport Channel Setup procedure an identification of an already-established channel to be used as the shared common transport bearer. The radio network controller (26) then uses the already-established channel as the shared common transport bearer for transmitting Multimedia Broadcast/Multicast Service user data to user equipment units (30) situated in plural cells served by the radio base station.

摘要： The present invention relates to methods and arrangements for facilitating an efficient connection setup. The present invention specifies rules for defining the signaling of connection setup messages from user equipments such as to apply one single transmission if an assigned uplink transmission grant for transmitting the connection setup messages is sufficiently large while applying separate transmissions if the size indicated in said uplink transmission grant is not sufficient. Thus, a sufficiently large grant allows a parallel execution of the connection setup messages.

摘要： An arrangement, control unit, and method in a cellular telecommunication system for allocating packets in a packet data stream to different base stations for transmission to a mobile terminal. The control unit receives the packet data stream in a main queue and identifies a plurality of base stations having sufficient signal strength to communicate with the mobile terminal. A data splitter splits the data stream into a number of sub-streams containing different data packets from the packet data stream. The sub-streams are buffered in a number of sub-queues, each of which is connected to a different base station. Packets are allocated to the sub-queues to maintain equal numbers of packets in each sub-queue, or to maintain a specified quality of service level for each sub-stream. The base stations independently transmit their sub-streams to the mobile terminal. Error-control coding may be applied to the packets to enhance macro diversity benefits.

摘要： The present invention relates to a node and a method in a cellular radio network telecommunication system for assigning resources to users, comprising a network node having resources to be allocated to users being present in a radio cell served by the network node. The invention comprises: - assigning a priority to each user in the radio cell, where a user consuming a larger portion of the resources is assigned a lower priority than a user consuming a lower portion of the resources, - receiving a rate request, requesting a larger transmission rate, from a first user having a first priority. If not sufficient free resources are available to fulfil said first users rate request, the following steps are performed: - selecting a second user having lower priority than said first user, - sending messages to said first and second users indication the scheduled grant, and - transferring resources, assigned to said second user, from said second user to said first user, to thereby decrease the consumed resources for said second user and increase the consumed resources for said first user.
