摘要： Radio resources are allocated to communication between a mobile station (40) and a base station (20). The available set of radio resources may comprise radio resources primarily assigned to a neighbouring cell if the 5 mobile station (40) experience an instantaneous low level of co-channel interference from such neighbouring cells. The existence of interference is preferably deduced from signal quality measurements of pilot signals. The allocation may concern uplink and/or downlink (54) communication. Devices (41) for performing the measurements are located in the mobile station (40), while devices for performing the evaluation (22), selection (23) and actual allocation (24) can be placed in different parts of the communications system- in the mobile station (40), in a base station (20) or In a core network node (70), or as a distributed means.

摘要： A set of different pilot structures are designed for use in different environments and/or different user behaviours that are expected to occur in a cell. The radio conditions for a user are estimated. Each user is then assigned an area (108A-E) in resource space for its communication, which has a suitable pilot configuration. In one embodiment, the entire resource space is provided with different pilot structures in different parts (110A-D) In advance and allocation of resources to the users are then performed in order to match estimated radio conditions to the provided pilot structure. In another embodiment, allocation is performed first, and then the actual pilot structure is adapted within the allocated resource space area to suit the environmental conditions.

摘要： A method for use in a cellular, FFT based multi-carrier communications system comprising N sub-carriers, for allocating a set P of sub-carriers to be reserved for potential use as carriers of specific information, comprises the following steps:- selecting a number M indicating the number of sub-carriers to be allocated to a set P of sub-carriers, such that L=N/M is an integer- allocating the at least two subcarriers of the set P={(n 0 +m*L) mod N : 0≤m 0 being the offset of the lowest numbered subcarrier in P, the elements of P being indices, each referring to the number of a sub-carrier to be allocated.

摘要： In a system applying orthogonal frequency division multiplexing, OFDM, a number of carriers are reserved for communication between unsynchronised nodes (N1, N2). At least one such reserved carrier is assigned to each base station. A sinusoidal signal is transmitted on this reserved carrier during a time period at least equal to two consecutive OFDM symbols. The unsynchronised receiver detects the sinusoidal signal during one of two consecutive OFDM symbol time periods. The existence, the frequency and the signal power of the signal give information about the existence and Identity of the transmitter. Also, estimates of relative velocities and distances can be deduced. In preferred embodiments, the sinusoidal signal can also be used to transmit further information by using signal modulation or coding that is independent of the absolute signal phase.

摘要： The invention relates to a method for scheduling resources for uplink transmissions in a radio access network comprising access points which own pre-assigned resources. The invention also relates to an access point (5-7), a user terminal (1-4) and an access point controller 8. Characteristic features of the invention are that each AP places its resources to the disposition of other APs in the access network, and that an AP (7) transmits a blocking signal (BLOCK R3) if it does not allow a UT (3) , which is served by an AP (5) in another cell, to use its resources (R3). A UT that detects a blocking signal from an AP that owns the resources on which the UT is transmitting immediately stops transmission on said resources. The signal quality of a detected blocking signal may be used for setting the transmission power on the resources the UT has borrowed from the AP which transmits the blocking signal. Based on statistics on the APs which transmit blocking signals long-term pre-allocation of resources among the APs is made.

摘要： Channel state feedback is provided from a UE (800) to a base station (700) as a first, detailed or a second, less detailed type of channel state feedback information. Initially it is determined (403) whether the UE has received an uplink grant from the base station or not. If the UE has received an uplink grant, a first type of channel state feedback information is transmitted (404) to the base station on the granted resource. If, however, the UE has not received an uplink grant, a second type of channel state feedback information is transmitted (405) to the base station. Different types of channel state feedback information enables a UE and an associated base station to use available resources more efficiently, when requesting for and delivering channel state feedback information.

摘要： An arrangement for controlling energy consumption of a network node associated with a cell includes a terminal activity monitor (16) configured to detect active terminals served by the cell. A transmission controller (18) is connected to the terminal activity monitor and is configured to restrict transmission downlink in the cell during time periods when there are no active terminals served by the cell. During these time periods transmission is restricted to inermittent transmission of information assisting active terminals not served by the cell in finding the cell.
