Abstract
The utility model relates to equipment for indicating a field to be addressed to temporary block flow and equipment for processing the field. The field is a piggyback PAN field. A PCS is generated, for example, the coding is performed by using CRC. The PCS is masked by a TFI assigned to a TBF or a mask code generated on the basis of the TFI. The PCS comprises the PAN field and a masked PCS data block which are processed so as to be convenient for transmitting. The mask code is generated by using (M, N) codes to convert the TFI, and the M is not larger than the bit number of the PCS and the N is the bit number of the TFI. Through the technical scheme, the TFI can be transmitted in the PAN field, and the TBF is recognized without an explicit bit.
Description
Technical field
The utility model 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 replying/non-replying (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 the uplink radio module 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.
The utility model content
A kind of equipment 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 described TFI and is produced, 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.
