摘要： Mechanisms to provide independent DRX (discontinuous reception) functionalities for individual carriers of a multi-carrier wireless network (200) are described. DRX is a higher layer functionality indicating which TTIs (transmission time intervals) a user equipment (220) needs to read for control signals. Operating in the DRX cycle allows the user equipment (220) to reduce battery consumption. A connection is established between a base station (210) and the user equipment (220) over a plurality of carriers, where for each carrier, an independent DRX cycle is established. The plurality of carriers include anchor carriers which can carry commands from the base station (210). The anchor carriers have shorter DRX cycles than the non-anchor carriers. When a large amount of download data is to be transferred, the DRX cycles of multiple carriers are overridden and used for transfer to achieve fast download rates. The override commands are sent from the base station (210) to the user equipment (220) prior to the transfer.

摘要： The present invention provides a method, a radio base station (40) and a mobile terminal (50) for allocating resources in a telecommunications network, where communications between the radio base station (40) and the mobile terminal (50) take place over a plurality of carriers. The method comprises transmitting and receiving a resource allocation message comprising one or more bits. Each of the bits corresponds to a number of resource blocks, where the number is determined from the ratio of the aggregate bandwidth of the plurality of carriers divided by the bandwidth of the carrier over which the resource allocation message is sent.

摘要： Ascertaining a signal power of an Orthogonal Frequency Division Multiplexing (OFDM) signal involves ascertaining a plurality of channel estimates from the OFDM signal. Compensating phase shift values for phase aligning the plurality of channel estimates are estimated and used to generate phase corrected channel estimates. The phase corrected channel estimates are coherently combined, thereby ascertaining the signal power of the OFDM signal. The compensating phase shift values may be based on a channel characteristic (e.g., delay spread) or may alternatively be hypothesized.

A method for controlling transmission parameters in the wireless communication system comprises the steps of: transmitting an indication indicating that the first and the second receiver processing algorithms are used in the first transceiver to process the first and second portions, respectively, of signals received on the physical channel; receiving the indication at the second transceiver; and adjusting, at the second transceiver in response to the indication, a transmission parameter for at least one of the first and second portions of signals to be transmitted on the physical channel to the first transceiver. The indication could be transmitted from the first transceiver, or it could be determined through evaluations carried out at the second transceiver.

摘要： A Signal-to-Interference Ratio of a radio channel is estimated in a receiver of a wireless communications system, wherein pilots with reference information are modulated on some sub-carriers in some symbols. At least one parameter for signals received from said first transmitter is detected, and a number (Nf, Nt) of pilots in first groups that can be coherently combined in a second group is determined, and from these a channel estimate (H) for each first group and a first covariance estimate (R) for each second group are determined. A number (M) of first covariance estimates that can be averaged is defined in dependence of the presence of signals from possible interfering transmitters, and a second covariance estimate is determined as an average of said number of first covariance estimates. From the channel estimates and the second covariance estimate a Signal-to-Interference Ratio for each second group is estimated.

摘要： Methods and apparatus that improve interference (I) estimation in CDMA systems in which the DPCH is sorted under a scrambling code different from the scrambling code of a channel such as the CPICH are described. In such systems, DPCH I-estimation cannot be done by measuring on the CPICH and transforming to the DPCH due to the different interference situations on the two channels. Instead, the DPCH interference is estimated by using knowledge of empty channelization codes in the alternative or secondary scrambling code that can be used for I estimation, or using symbols (e.g., control symbols on the DPCCH) on the DPCH, or searching for an empty channelization code and using a found empty code for I-estimation. These techniques improve the SIR estimate in comparison to prior techniques and hence also improve the performance of power control, increasing the system's capacity.

摘要： A cell searching procedure is modified to enable a user terminal to determine whether a detected signal originates in a known cell or a new cell having the same cell identifier as the known cell. When a signal is detected, the user terminal determines the cell identifier and timing of the detected signal. If the cell identifier matches a known cell and the timing is outside the timing window of the known cell, the user terminal compares detected signal with a corresponding received signal received from the known cell having the same cell identifier as the detected signal source. The user terminal determines, based on said comparison, whether the detected signal is from the known cell or a new cell.
