摘要： A user device on a wireless network includes a receiver, a noise detector and a noise determiner. The receiver receives downlink data communications from a base station that indicates an allocation of time/frequency resource blocks at least to user devices that are communicating with the base station. The noise detector measures noise in a time/frequency resource block, comprising plural time/frequency bins, that is not allocated to one of the user devices. The noise determiner determines a level of interfering noise based on noise in the resource block that is not allocated to one of the user devices.

摘要： A method in a Multiple-Input Multiple-Output (MIMO) transmitter includes selecting a transmission mode from a group of modes including a spatial multiplexing mode and a transmit diversity mode. A rate matching parameter is set depending on at least the selected transmission mode. Data for transmission is formatted in one or more transport blocks, each transport block including multiple code blocks having respective lengths, in symbols, that are respective integer multiples of the rate matching parameter. The code blocks of a given transport block are mapped onto time-frequency resource elements in accordance with the selected transmission mode, such that each resource element contains data originating from only a respective one of the code blocks of the given transport block. The code blocks of the given transport block are transmitted over the time-frequency resource elements to a receiver.

摘要： A method includes receiving a signal via multiple receive antennas. A noise covariance matrix, which indicates noise correlations between pairs of the receive antennas, is estimated. A stability criterion defined over the noise covariance matrix is evaluated, and the noise covariance matrix is modified when the stability criterion is violated. The received signal is processed using the modified noise covariance matrix.

摘要： A mobile user equipment includes a user equipment clock and a dual mode time tracker. The clock periodically wakes up the user equipment. The dual mode time tracker uses a serving cell reference signal to correct timing errors of the user equipment clock with respect to a network clock while timing errors remain minimal and otherwise uses a serving cell synchronization signal to correct timing errors of the user equipment clock. The dual mode time tracker also sets a next wakeup time as a function at least of the size of the timing errors.

摘要： A method includes receiving at a receiver a signal including reference symbols that is sent over a communication channel from a transmitter to the receiver. A response of the communication channel is estimated by applying one or more weighting values to the reference symbols. A noise correction factor is computed based on the weighting values. An estimate of a noise level in the received signal is computed based on the estimated response of the communication channel and the noise correction factor. The received signal is decoded based on the estimate of the noise level.

摘要： A method in a communication system, in which multiple transmitters transmit respective control messages to a receiver over a control channel, includes allocating respective resources of the control channel to the control messages so as to cause a respective likelihood of interference between a control message and at least one other control message to be inversely related to a respective impact of the interference between the control message and the at least one other control message on an overall performance measure defined for the communication system, by allocating a dedicated resource to a first control message for which the interference has a high impact on the overall performance measure, and allocating a shared resource to a second control message for which the interference has a low impact on the overall performance measure. The control messages are transmitted from the transmitters over the control channel using the allocated resources.
