摘要： A method, scheduler and a network node for scheduling retransmissions in a telecommunications system is described. The method comprises determining a scheduling point of time for a retransmission in a periodic interval cycle for transmissions in the network node, which point of time in the cycle is different as compared to the point of time in the cycle when the previous transmission was performed. The retransmission is then scheduled to be performed at that different point of time in the cycle, hence providing the placing of the data in a different position in the frame as compared to the data position of a previously interfered transmission of that data. This provides the advantage of providing an increased probability of avoiding that retransmitted data is again interfered in transmissions suffering from periodic interference problems.

摘要： The invention relates to management of data packets and buffers comprising segments of data packets in a mobile communication system (1). Information associated with data packet segments is analyzed by a Base Station System (BSS) (100) housing a data buffer (120). Based on this information analysis, the BSS (100) can identify those segments (P(FIRST) - P(LAST)) in the buffer (120) that constitutes a complete data packet. Once identified, the segments can be discarded from the buffer (120). The information can include size information (S(k), S(k+1)), whereby the analysis comprises pairwise comparing the size (S(k)) of a current segment (P(k)) with the size (S(k+l)) of a next consecutive segment (P(k+l)). This size comparison enables identification of a first segment (P(FIRST)) and a last segment (P(LAST)) of the complete data packet. The information could also, or alternatively, include a notification provided in the header of the segment. This notification identifies the associated segment as the first or last segment of the data packet or an intermediate segment.

摘要： The present invention relates to cellular communication systems and to the random access procedure. An uplink random access channel RACH is available in each cell for out-of-sync terminals to be able to access the system. A RACH window must be long enough to accommodate bursts send sent from terminals at the cell boarder as well as from terminals close to a receiving base station. In general the RA-window is dimensioned for a basic cell range. The RACH capacity is further dimensioned by the frequency allocation and the period of repetition of the RA-window. A problem is if the geographical coverage is to be extended to cover more than the basic cell range, because the length of the RA-window needed for terminals at the cell range will take much of the uplink transmission capacity, to the disadvantage of other traffic. The present invention solves the problem with two RACH1 with different window lengths. One RACH intended for terminals in the inner cell and the other for terminals in the outer cell. The advantage is the capacity of each RACH can be dimensioned in proportion to the load of RACH bursts.
摘要翻译：本发明涉及蜂窝通信系统和随机接入过程。上行链路随机接入信道RACH在用于不同步终端的每个小区中是可用的，以能够访问系统。 RACH窗口必须足够长，以适应从小区主持人的终端以及靠近接收基站的终端发送的突发信号。一般来说，RA窗口的尺寸适用于基本单元格范围。 RACH容量进一步由频率分配和RA窗口的重复周期来确定。问题是如果将地理覆盖范围扩展到覆盖超过基本小区范围，因为在小区范围内的终端所需的RA窗口的长度将占用大量的上行链路传输容量，这是其他流量的缺点。本发明解决了具有不同窗口长度的两个RACH1的问题。一个RACH用于内部小区中的终端，另一个用于外部小区中的终端。优点是每个RACH的容量可以与RACH脉冲串的负载成比例。

摘要： A method (700) for use in a cellular system (200) comprising a plurality of base stations (112, 122, 132, 142) for the control of the traffic to and from a cell (110, 120, 130, 140), in which system (200) the communication between users in a cell and their base station is divided into an up link period (UL), and a down link period (DL), with guard periods between uplink and downlink periods. Each base station utilizes time information from one of a number of synchronization sources in order to time the down link, up link and guard periods properly. The method comprises letting each of the base stations use information on the inaccuracy of the synchronization source of the base station in order to adapt its downlink periods so that they do not interfere with up link periods in one or more of the other base stations in said plurality.
