摘要： Appropriate data communication is realized.
A wireless communication device includes a communication unit and a control unit. The communication unit included in the device performs data transmission to a different device via one of frequency channels classified into a plurality of groups that includes a first group and a second group. On the other hand, the control unit detects a reference signal transmitted from the different device via one of the frequency channels belonging to the first group. The control unit further selects one of the frequency channels for the data transmission from the first group or the second group on the basis of a result of detection of the reference signal.

摘要： Techniques for facilitating and performing frequency-offset estimation are disclosed. The disclosed techniques include methods and apparatus for maintaining phase coherence among reference symbols on different transmission-time intervals (TTI) for an accurate estimation of frequency offset. Corresponding techniques utilize channel estimation or measurements of channel-related parameters based on multiple reference symbols belonging to different TTIs. An example method in a radio transceiver for facilitating frequency offset estimation at a remote receiver begins with determining that phase coherence between reference symbol transmissions in a first TTI and a second TTI is required. The radio transceiver selectively maintains phase coherence between reference symbol transmissions in the first and second TTIs, in response to said determining. The radio transceiver then transmits during at least part of a third TTI, following the second TTI, without maintaining phase coherence to the reference symbol transmissions in the first and second TTIs.

摘要： The present invention relates to orthogonal frequency-division multiplexing (OFDM) communication systems with four transmit antennas and one or more receive antennas, and in particular to methods for inserting scattered pilots (SP) into the transmit signals of such OFDM systems, for estimating channel properties on the basis of the scattered pilots, a multi-antenna OFDM transmitter, and an OFDM receiver. In this context, it is the particular approach of the present invention to keep the same SP pattern like in the single-transmitter case, to partition the pilots into as many subsets as there are transmit antennas, and to interleave these subsets both in time and in frequency. In this manner, the granularity of pilots of the same subset is reduced. This offers increased flexibility in designing the scattered pilot patterns and greater accuracy of the estimated channel properties.

摘要： Methods and apparatus are provided for a User Equipment (UE) to transmit a Sounding Reference Signal (SRS). Afirst Downlink Control Information (DCI) format with an aperiodic SRS request field indicating aperiodicSRS transmission with first values for aperiodic SRS transmission parameters, is received. A second DCI format with an aperiodic SRS request field indicating aperiodic SRS transmission with second values for the aperiodic SRS transmission parameters, is received. The first values for the aperiodic SRS transmission parameters are compared with the second values for the aperiodic SRS transmission parameters. An aperiodic SRS is transmitted when the first values are identical to the second values. Transmission of the aperiodic SRS is suspended when the first values are not identical to the second values.

摘要： In a method of adjusting a modulation and coding scheme (MCS) level for a transmission on a communication channel between a base station and a mobile terminal, at the base station: a target value for an error metric is defined; the error metric is measured; an MCS offset based on a degree of deviation of the measurement of the error metric from the target value is determined; an indication of a channel quality measurement for the communication channel is received from the mobile terminal; a pre-adjusted MCS level corresponding to the indication of the channel quality measurement is determined using a fixed mapping between a set of channel quality levels and a corresponding set of MCS levels; an adjusted MCS level is determined by adding the MCS offset to the pre-adjusted MCS level; and the adjusted MCS level is assigned to the transmission.
