摘要： A system and method for creating a number of phase reference points in a data frame is provided. When a sequence of data bits is to be transmitted, the sequence is precoded into data symbols and organized as data frames. For each data frame, an x number of phase reference points at predetermined intervals within the data frame are required to allow a receiver to sufficiently estimate channel effects on the transmitted data frame. To set the phase reference points, one of the phase reference points is first selected. An x-1 number of pilot symbol sets are then created and inserted into the data frame such that each of the other reference points has the same phase state as the selected phase reference point.

摘要： A method of wireless communication with improved performance employs an equalizer receiver with multiple receive antennas. Equalizer taps for linear filters of the equalizer receiver are generated by determining a conditioned covariance matrix of a first data path and a second data path based on a first gain (g0) of this first data path and a second gain (g1) of the second data path. The equalizer taps of the first data path and the second data path are determined based on the conditioned covariance matrix. The first data path and the second data path are then equalized using the equalizer taps. An equalized signal is generated by combining the equalized first data path with the equalized second data path.

摘要： Systems and methodologies are described that facilitate synchronizing base stations in a wireless communication environment. A base station can receive a synchronization signal sent via a low reuse channel, which can be shared by a group of base stations. Further, the base station can align a clock associated therewith to the received synchronization signal. Moreover, the base station can coarsely align the clock to a first synchronization signal received upon a first subset of resources of the low reuse channel, and finely align the clock to a second synchronization signal received upon a second subset of resources (e.g., of the low reuse channel, of a separate channel, . . . ), where the second subset of resources can be reserved for transmission from at least one base station with at least a predetermined level of synchronous accuracy.

摘要： Systems and methodologies are described that facilitate synchronizing timing among wireless nodes in a wireless communication network. A tracking wireless node can synchronize to a global positioning system (GPS) signal if available. Alternatively, the tracking wireless node can receive quality metrics related to one or more target nodes. The quality metrics can relate to parameters that can be utilized to evaluate the target node for timing synchronization. Based on the quality metrics, the tracking wireless node can select a target wireless node for timing synchronization. The tracking wireless node can subsequently synchronize timing with the target wireless node. In addition, the tracking wireless node can continually evaluate surrounding wireless nodes to detect whether other wireless nodes have higher quality metrics than the current target wireless nodes and can accordingly resynchronize with nodes having higher metrics.

摘要： A telecommunication system includes one or more radio access network controllers and one or more radio base stations. A radio access network controller supervises the operation of a radio base station. To facilitate the supervision process, the radio access network controller receives a measurement capacity report from the radio base station and determines measurement control parameters specifying reporting requirements of the radio base station. The measurement control parameters are continually adjusted so that the capacity of the radio base station is not exceeded. Also, the capacity of the radio network controller is also considered in determining the measurement control parameters.

摘要： Certain aspects of the present disclosure provide techniques for channel state information (CSI) processing occupation determination that can be used even in multiple transmission reception point (mTRP) scenarios. A method that may be performed by a user equipment (UE) includes receiving a channel state information (CSI) reporting configuration configuring the UE with a plurality of CSI reference signal (CSI-RS) resources for channel measurement (CMRs). The method includes determining a number of occupied CSI processing units, a number of occupied active CSI resources, and/or a number of occupied active CSI-RS ports based on an actual number of CSI measurements. The method includes performing CSI measurement based on the determination.
