    摘要: A method for use in a cellular access system is disclosed. The system comprises at least one Radio Base Station (RBS) which controls traffic to and from a cell in the system. The cell can have a User Equipment (UE) in it, such that the UE and RBS can send and receive data blocks, which may comprise sequence numbers, to and from each other. The RBS and UE can also exchange reports comprising information on whether or not data blocks have been received successfully. The method comprises sending by a reporting party a transmission comprising a report to the report receiving party, said report comprising information on whether or not data blocks have been received successfully. The method further comprises sending by the reporting party said report together with data to the report receiving party or to another party. The method further comprises attaching by the reporting party addresses for a recipient of the data blocks and for the report in the transmission. The method further comprises deciding by the reporting party the contents of the report using at least one of the following priority rules which have been given an internal priority ranking, in which data blocks which are identified as having a lower delay tolerance than other data blocks are given priority; data blocks which have been detected as received in error, and whose status has not been reported since the error was detected are given priority; and, data blocks are given priority according to their sequence numbers.

    摘要: A method (200) for a cellular system (100), with an RBS (120) which controls a cell (110) with User Equipments UE (130, 140). The RBS and the UEs exchange data which may comprise sequence numbers, and exchange reports on whether or not data has been received successfully, so that both the UE and the RBS can be the reporting party and the report receiving party. The reporting party sends a report (210) to the report receiving party on whether or not data has been received successfully, together with data to the report receiving party or to another party in the cell. The reporting party decides (220) the contents of the report using one of the following priority rules: Data with lower delay tolerance is given priority, Data detected as received in error is given priority, Data is given priority according to block sequence numbers.

    摘要: In a communication terminal implementing a radio link control (RLC) protocol, error propagation to higher layer protocols is mitigated by use of an additional length indicator, referred to herein as a new packet indicator, in the RLC data blocks to indicate the beginning of a new higher layer packet in addition to a conventional length indicator to indicate the last segment of a higher layer packet. The new packet indicator prevents the Logical Link Control (LLC) data segment at the beginning of an RLC data block from being concatenated with an LLC data segment in the previous data block even when length indicators in the previous data block are not received.
