摘要： A method of estimation of harmonic distortion level for a radio receiver operative in a cellular communication system enabled to receive signals from transmitters of one or more cells is disclosed. The method comprises measuring, within a bandwidth of operation, a total received signal power; measuring, within the bandwidth of operation, a received signal power of signals received from the one or more cells, respectively; and estimating a level of harmonic receiver distortions by: determining whether a fraction of the total received signal power and a theoretical noise floor is below or above a first threshold; or determining whether a remaining part of the total received signal power, said remaining part not including said fraction, is above or below a second threshold. A such radio receiver, and a computer program for implementing the method are also disclosed.

摘要： Methods and apparatus are provided for detecting the radio access technology (RAT) employed in a received signal prior to performing a cell search. The RAT detection method may be used to identify the most likely RAT employed for each candidate frequency identified in an initial frequency scan. Once the most likely RAT is identified, the mobile communication device can then attempt synchronization according to the procedures for the most likely RAT. Identifying the RAT prior to the cell search reduces the number of synchronization attempts and, consequently, the time needed to perform the cell search.

摘要： Decoding a received Orthogonal Frequency Division Multiplex (OFDM) signal that occupies a first set of subcarriers in a radio frequency spectrum includes ascertaining an interference model that represents interference occurring in the first set of subcarriers caused by a transmitted OFDM signal that occupies a second set of subcarriers in the radio frequency spectrum. A set of scaled soft values is produced that represents information conveyed by the received OFDM signal over the first set of subcarriers, wherein each scaled soft value in the set of scaled soft values corresponds to a respective one of the subcarriers in the first set of subcarriers, and wherein a scaling amount applied to each of the scaled soft values is based on a corresponding level of interference in said respective one of the subcarriers as indicated by the interference model. A decoding process is performed that generates detected data from the scaled soft values.

摘要： A terminal with transmitter and receiver operates in a multi-carrier communication system and receives at least two downlink carriers. One or more timing advance commands are received, each associated with a group of one or more uplink carriers, each group being associated with one or more of the received downlink carriers. For each downlink carrier associated with one of the groups of uplink carriers, one is selected as a reference downlink carrier; the reference downlink carrier timing is ascertained; and a transmission time period is ascertained based on the timing of the downlink reference carrier and an offset specified by the timing advance command associated with the group of uplink carriers. The transmission time period comprises a start time and a stop time. Transmission is initiated at an earliest transmission start time of the ascertained transmission time periods and is ceased at a latest ascertained stop time.

摘要： Wireless transmissions from a user of a spectral resource are sensed by operating receiver equipment within a user equipment to receive signals within a given bandwidth around a given carrier frequency. If the user equipment is not readily capable of analysing the received signals to ascertain whether the signature pattern of the user is present in the received signals, then it works cooperatively with a remote unit to analyze the received signals to ascertain whether a signature pattern of the user is present in the received signals. Results of the analysis are reported to a main node. The remote unit can provide software to the user equipment and/or perform at least part of the analysis for the user equipment.

摘要： In one or more aspects, the method and apparatus presented herein consider corresponding uplink resource allocations when allocating ARQ signal powers. In particular, in at least one embodiment, more power is allocated to the acknowledgment ("ack") signal(s) corresponding to user equipment (UE) transmissions that involve larger allocations of uplink resources. For the example context of an LTE network, an eNodeB "boosts" its ack signaling power for acknowledging UE transmissions associated with larger uplink bandwidth allocations. Additionally, or alternatively, the UE is configured to bias its ARQ signal evaluations, to bias its ack/nack decision determinations to favor the ack decision, at least for those acks associat

摘要： Allocation of cell IDs in a cellular communication system includes determining a candidate allocation pattern of primary and secondary synchronization signal sequences for a candidate set of two or more cells. A performance metric is applied to the candidate allocation pattern to ascertain a performance indicator for the candidate allocation pattern, wherein the performance indicator indicates a quality of positioning performance for the candidate set of two or more cells. Cell-specific positioning performance for each cell in the candidate set of cells can be considered to derive the performance indicator of the candidate allocation pattern. If the performance indicator indicates acceptable positioning performance, primary and secondary synchronization signal sequences are allocated to respective ones of base stations corresponding to the two or more cells in accordance with the candidate allocation pattern. Otherwise, the process is repeated for a different candidate allocation pattern.

摘要： The present invention relates to methods and arrangements in a multi-carrier system. It also assumes independent DRX (Discontinuous reception) functionality on respective component carriers and the possibility for one carrier, e.g. the anchor carrier to initiate a change of DRX state for another component carrier. The basic concept of the present invention is to introduce a new "dormant" state in the DRX logic, whereby the dormant state can be used for non-anchor carrier components. The dormant DRX state implies that a carrier of a UE having this state is not required to monitor system signaling. In embodiments of the present invention this new state is introduced for a particular component carrier (e.g. non-anchor component carrier) for a UE operating in a multi-carrier system, and how to perform the transitions to and from the dormant DRX state implicitly, e.g. based on configured timer(s) for the component carrier or explicit signaling in a different (e.g. anchor) component carriers.
