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： The invention relates to a method for maintaining a synchronised upward signal transmission in a radio communication system. Said radio communication system supports a TD/CDMAT user separation method, for the signal transmission on a radio interface, between a base station and at least one user station, whereby said radio interface is organised according to a TDD method. A relative delay in the reception of a downward signal at the user station is determined, after an effective synchronisation and said delay is used to control the timing of the subsequent transmission of signals in the upwards direction.

摘要： The invention discloses a method for a cellular system (100) which uses TD- SCDMA, Time Division Synchronous Code Division Multiple Access. According to the method, MBMS services, Multi media Broadcast Multicast Service, are enabled in a first (120) and a second (160) cell in the system, so that there can be both MBMS and non-MBMS users (130,170; 140; 180) in said first and second cells at one and the same time. According to the method, traffic to non-MBMS users (140, 180) in the first and second cells is sent using one and the same basic midamble code per cell which is shifted between the different non-MBMS users in each cell, and the traffic to MBMS users (130, 170) in both of said first and second cells who use the same MBMS services is varied between the cells with respect to the basic midamble code or/and the midamble shift.

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.
