摘要： A method of a wireless communication device for a cellular communication system is disclosed. According to the method, a signal comprising a first known signal sequence and a second known signal sequence for each of one or more first cells of the cellular communication system is received, and the first and second known signal sequences of each of the one or more first cells are detected based on the received signal. For at least one of the one or more first cells, one of the first known signal sequence, the second known signal sequence, and a combination of the first and second known signal sequences is selected for channel estimation. The selection is based on the detected first and second known signal sequences of the one or more cells. Channel estimation of the at least one of the one or more first cells is performed based on the signal sequence selection. In some examples, the method may further comprise performing interference cancellation of at least one of the first and second known signal sequences of the at least one of the one or more first cells based on the channel estimation and detecting one or more second cells of the cellular communication system after the interference cancellation. Corresponding computer program product, arrangement and wireless communication device are also disclosed.

摘要： Example embodiments presented herein are directed towards a first radio node (400), and corresponding methods therein, for determining a bandwidth of a second radio node (402). The first and second radio nodes are configured for use in a communications network. The bandwidth is determined based on a correlation between a signal received form the second radio node and at least one known signal which are transmittable on one or more known radio resources. Such bandwidth determination eliminates the need for the wireless terminal to receive such information via system information broadcasted from a cell.

摘要： Methods and apparatus are disclosed for estimating a signal by a wireless device in a wireless communication system. The wireless device obtains a scaling factor that describes a relation between signal estimates for first and second signals of a first type. The wireless device further obtains a reference signal estimate that comprises a signal estimate for a first signal of a second type. The wireless device then selectively determines at the wireless device a signal estimate for a second signal of the second type by scaling the reference signal estimate by the scaling factor. The first signals of the first and second type are associated with a first radio network node. The second signals of the first and second type are associated with a second radio network node.

摘要： A communication system node transmits first control channel information on a control channel that extends over a first bandwidth of a radiofrequency resource. The first control channel information is necessary to enable a first type of communication device, capable of receiving a signal having the first bandwidth, to establish a connection with a host cell. A MIB, occupying a second bandwidth-size part of the first bandwidth, is transmitted. The second bandwidth is smaller than the first bandwidth and is receivable by a second type of communication device having reduced receive bandwidth capabilities. The MIB has a first part comprising first part information necessary to enable the first type of communication device to establish the connection with the host cell, and a second part comprising second part information directly or indirectly enabling the second type of communication device to obtain parameters that enable connection establishment with the host cell.

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： 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.
