摘要： Methods and arrangements, for supporting cell selection in a mobile terminal (UE1, 1101) associated with a set of serving cell candidates (Cell1, Cell2, Cell5, Cell7, Cell10). The method in the mobile terminal involves evaluating (804, 806) a first serving cell candidate (Cell5) from the set by estimating (804) the distance (d 5 ) from the mobile terminal to the first serving cell candidate and determining (806) whether the estimated distance exceeds a predetermined distance, based on a criterion. The method further involves refraining (810) from performing a call on the first serving cell candidate if the estimated distance exceeds the predetermined distance and instead evaluating (812, 814) a second serving cell candidate (Cell1) from the set. The methods and arrangements enable selection (808, 816) of a serving cell, from amongst the serving cell candidates in the set, within a predefined distance from the mobile terminal.

摘要： A relay node is operated in a communication system wherein the relay node communicates with a communication system node via a first link and communicates with user equipment (EU) via a second link. The relay node detects whether a collision between its own uplink transmission on the first link and receipt of the user's transmission on the second link at a future time instant is expected to occur, wherein the collision will interfere with the relay node's ability to receive the UE's transmission. If so, then, the relay node selects and executes one of a plurality of interference averting measures, selection being based at least in part on what type of information is expected to be transmitted and received on the respective first and second links. First and second interference averting measures comprise refraining from or proceeding with transmission of some information to the communication system node.

摘要： Methods and a receiver of positioning a spurious signal for reducing the impact of the spurious signal on a received Orthogonal Frequency Division Multiplexing, OFDM signal, are presented. The method comprises determining the frequency of a spurious signal (steps 102, 204, 404), determining the frequency for the respective sub-carrier of the OFDM signal and the difference between the frequency of a sub-carrier and the frequency of a spurious signal (steps 104, 206, 406), and adjusting at least one of: the frequency of the first oscillator (step 208) and a parameter related to the frequency of a second oscillator, to decrease the frequency difference between a sub-carrier and a spurious signal (steps 106, 212, 408). By positioning a spurious signal at or near a sub-carrier frequency, the performance impact of the spurious signal is reduced, and the receiver performance improved.

摘要： A wireless communication transceiver compensates a given received signal for retransmission interference, if (uncompensated) decoding of the given received signals fails. The transceiver estimates the retransmission interference bearing on the given received signal based on hypothesizing that another user (or users) mistakenly transmitted in the same time interval, using some or all of the same channel resources as were allocated to the given received signal. The transceiver may retain information in any given interval, indicating the channel allocations used for those user signals successfully received in that interval. The retained information allows the transceiver to determine, with respect to a given signal received in a current time interval, which other users would be interfering users if they mistakenly retransmitted in the current time interval. The transceiver may target its compensated decoding, which may be iterative, to the most likely and/or most significant ones of the potentially of interfering user(s).
