摘要： A mobile station comprises a radio communication unit (22) for communicating with a radio communication network for finding carriers on which transmissions are being made in active transmission intervals of a transmission cycle following a discontinuous transmission scheme. The radio communication unit is configured to select a carrier based on probability settings provided for each carrier of the scheme, scan the selected carrier during a time range that is a fraction of the transmission cycle, confirm the presence of the carrier if transmissions are detected and otherwise to adjust the probability settings of the carriers based on the timing of the scanning and the position of the carrier active transmission interval in the transmission sequence and repeat the selection of carrier based on probability settings and adjusting of probability settings until the presence of a carrier has been confirmed.

摘要： A base station reduces interference from user equipment operating in a neighboring cell by monitoring one or more channels of neighboring base stations to receive a signal transmitted by a user equipment that is being served by one of the neighboring base stations, and detecting when a power level of the signal transmitted by the user equipment exceeds a threshold power level. The base station then uses the received signal transmitted by the user equipment to acquire an identifier of the user equipment. The base station then communicates with a network node of the mobile communication system to arrange for it to serve the user equipment itself but in only the uplink direction. The neighboring base station continues to serve the user equipment in the downlink direction in what is now an asymmetrical uplink/downlink connection.

摘要： In one aspect, the present invention provides methods (400, 900) and apparatuses (22, 26, 40) for detecting that a wireless communication device (40) in a serving cell (24, 27) is experiencing excessive interference variance (68), detecting a transmission pattern (74) of interfering transmissions (46) giving rise to such variance, and correspondingly adjusting scheduling of the device (40) as a function of the detected transmission pattern (74), to at least partly avoid the interfering transmissions (46). An advantageous feature of such operation is that the determination of excessive interference variance (68) and the determination of the transmission pattern (74) associated with that varying interference can be done by a network node (22, 26), e.g., the device's serving base station (22, 26), or by the device (40), without requiring backhaul signaling or other inter-node cooperation in the network (20).

摘要： A method of scheduling wireless data transmissions between a mobile terminal (701) and a base station using multiple component carrier signals is disclosed. The method comprises the steps of: receiving in the mobile terminal information from the base station indicating available component carriers; detecting in the mobile terminal at least one dynamic parameter indicative of the mobile terminal's current ability to handle component carriers having non-contiguous bandwidths; determining in the mobile terminal in dependence of the at least one dynamic parameter which of the available component carriers to utilize; and transmitting from the mobile terminal to the base station information indicating the component carriers determined to utilize. By doing this the mobile terminal may choose to limit the number of component carriers used in situations where it is disadvantageous, such as situations where the power consumption of supporting multiple component carriers is high or situations where complex hardware is needed.

摘要： A communication device has a plurality of concurrently operating transceiver systems, each operating in a respectively different one of a plurality of communication systems. Operation of the transceiver systems is coordinated by receiving a plurality of requests from different ones of the transceiver systems, each of the requests being a request to access a communication medium for the purpose of transmitting or receiving a data packet. Utilization of an available time period is scheduled by selecting which one or ones of the requests to grant based, at least in part, on how many remaining times out of a maximum number of times each of the transmission systems' data packet is permitted to be retransmitted compared to other requests, on whether the requests are requests to transmit a data packet, and on whether the requests are requests to receive a data packet.

摘要： A method of scheduling wireless data transmissions between a mobile terminal and a base station using multiple system carrier signals is disclosed. The method comprises the steps of receiving (101) the mobile terminal information from the base station indicating available system carriers; detecting (102) at least one dynamic parameter indicative of the mobile terminal's current capability to handle non-contiguous system carriers; determining (103) from the dynamic parameter whether a situation has occurred where the mobile terminal's capability to handle non-contiguous system carriers has been reduced; modifying (104), in such case, feedback information to be transmitted to the base station; and transmitting (105) the modified feedback information to the base station. By modifying the feedback information in this way the mobile terminal reduces the likelihood that the base station allocates non-contiguous system carriers to the mobile terminal in situations where it has a reduced capability of handling such system carriers.

摘要： The present invention relates to scheduling of uplink and downlink resources between mobile terminals (110, 120) and a base station (130). To reduce the power leakage between the transmitter and the receiver of the mobile terminal (110), the scheduler allocates uplink frequency carriers and downlink frequency carriers with a large duplex distance to those mobile terminals (110, 120) that have to transmit with high power. This means that the requirements on the external SAW filter could be reduced.

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.
