Method and Arrangement for Resolving a Temporary Block Flow

摘要

A method for resolving a Temporary Block Flow (TBF) in a wireless network including one or more mobile stations exchanging data with a base station system. The method comprises receiving a RLC/MAC block and retrieving a first TFI in the RLC/MAC header. The TFI is compared to an assigned TFI. The capability for the associated MS to resolve TBFs based on extended TFI addressing is determined. If the received first TFI matches assigned TFI and represents a comprehensive TFI for the associated MS, the payload of the RLC/MAC block is decoded. When the first TFI matches assigned TFI value and is identified as a code point to an eTFI, at least a predetermined field of the RLC data block is decoded and an extended TFI, eTFI, is retrieved. The eTFI is compared with an assigned eTFI. Following a match, the payload of the RLC data block is decoded.

1. A method for resolving a Temporary Block Flow (TBF) in a wireless network including one or more mobile stations exchanging data with a base stations system (BSS) by means of one or more RLC/MAC blocks each associated with the TBF and wherein the TBF is associated to a mobile station and identified by means of a Temporary Flow Identity (TFI), the method comprising:
receiving a RLC/MAC block including an RLC/MAC header and an RLC data block; retrieving a first TFI from a first group of TFIs in the RLC/MAC header; comparing the first TFI with an assigned TFI; determining capability in the mobile station to retrieve an extended TFI, eTFI, field in a transmitted downlink RLC/MAC block; decoding the payload of the RLC/MAC block when the first TFI matches the assigned TFI and represents a comprehensive TFI for the associated mobile station; decoding at least a predetermined field of the RLC data block and retrieving an extended TFI (eTFI) from a second group of TFIs when the first TFI matches the assigned TFI value and is identified as a code point to an eTFI; comparing the eTFI with an assigned eTFI; decoding the payload of the RLC data block when the eTFI matches the assigned eTFI; disregarding the RLC/MAC block if the first TFI does not match the assigned TFI or the eTFI does not match the assigned eTFI; receiving a new RLC/MAC block and repeating the steps for said RLC/MAC block.
