Abstract
A method and apparatus for indicating a temporary block flow (TBF) to which a piggybacked acknowledgement/non-acknowledgement (PAN) field is addressed. A PAN check sequence (PCS) is created, for example using a cyclic redundancy check (CRC) encoding.. The PCS is masked with a temporary flow identity (TFI) assigned to a TBF or a mask generated based on the TFI. A data block including the PAN fieldand the masked PCS is then processed for transmission. The mask may be generated by converting the TFI using an (M, N) code, M being not greater than the number of bits of the PCS and N being the number of bits of the TFI. With this scheme, a TFI may be transmitted in a PAN field without using explicit bits to identify the TBF.
Description
Technical field
The present invention relates to wireless communication system.
Background technology
Reducing the stand-by period is to need one of factor of considering in the GSM/EDGE radio access network (GERAN).There are two kinds of technology to be suggested to reduce the stand-by period: to reduce Transmission Time Interval (RTTI) and rapid answer/non-replying (ACK/NACK) report (FANR).
Normally, ACK/NACK is reported in the explicit message and is sent out, and is also referred to as radio link control/medium access control system (RLC/MAC) controll block.Described ACK/NACK report is addressed to specific radio resource, is called Temporary Block Flow (TBF).
TBF is that interim connection between mobile radio station and the network is in order to support the data unidirectional delivery.TBF is interim and only keeps during described data passes.Each TBF is by network-assigned temporary flow identity (TFI).Be unique among the parallel TBF of described TFI on all directions and in rlc/mac layer, be used to replace moving station mark.Identical TFI is included in each RLC header that belongs to specific T BF.
Had method to propose the ACK/NACK report of certain TBF is sent as " incidentally (piggyback) " on the RLC/MAC data block, described RLC/MAC data block can be addressed to another TBF.The field of carrying described ACK/NACK report is called as ACK/NACK (PAN) field incidentally.
Because the PAN field is included in its address and may points in the data block of different TBF, therefore which TBF is necessary to discern described PAN field is addressed to.There has been multiple proposal to be used for discerning correct TBF in the described PAN field, comprised and utilize TFI or up link (UL) Status Flag (USF).During setting up up link TBF, USF is assigned to each mobile radio station.Described USF by network be used to refer to which portable terminal be allowed to after uplink radio block in transmission signals.
In either case, the bit of some numbers (typically from 3 to 5 scope) should be exclusively used in the TBF sign in the described PAN field.Thereby expecting to have a kind of effective ways that are used for sending the TBF sign of described PAN field does not need dedicated bit to discern described TBF.
Summary of the invention
A kind of method and apparatus that is used to indicate the TBF that the PAN field is addressed to has been described.Create PAN verification sequence (PCS), for example utilize the Cyclic Redundancy Check coding.Described PCS by being assigned to TBF TFI or come masked based on the mask that described TFI produces.Subsequently, comprise that the data block of described PAN field and masked PCS is processed so that transmit.Described mask can by utilize (M, N) sign indicating number is changed and is produced described TFI, M is the bit number of described PCS and the bit number that N is described TFI.By this scheme, TFI can be transmitted in the PAN field and not need to utilize explicit bit to discern described TBF.
