The indicating means of resource distribution location, system and device in a kind of random access procedure

Technical field

The present invention relates to access technology at random, be meant indicating means, system and the device of resource distribution location in a kind of random access procedure especially.

Background technology

In Long Term Evolution (LTE, Long Term Evolution) system, frame structure is divided into two types of frame structure Class1 (Frame structure type 1) and frame structure types 2 (Frame structure type 2).

There is Frequency Division Duplexing (FDD) (FDD in the frame structure Class1, Frequency Division Duplex) and time division duplex (TDD, Time Division Duplex) two kinds of patterns, its frame structure is shown in Figure 1A: the length of a radio frames (radio frame) is 10ms; Comprise 10 subframes (subframe) in the radio frames, the length of each subframe is 1ms; Each subframe comprises two time slots (slot), and the length of a time slot is 0.5ms.A Transmission Time Interval (TTI, Transmission Time Interval) is corresponding to a subframe.

Step 201: terminal sends random access leader sequence (Random AccessPreamble abbreviates Msg1 below as) at up direction to network.Msg1 is at Physical Random Access Channel (PRACH, Physical Random Access Channel) go up transmission, according to the difference of radius of society, Msg1 can be configured among the UpPTS, also can be configured in the conventional sub-frame of uplink, in subframe 1 (subframe#1).

Step 202: after network is received random access leader sequence, send accidental access response (Random Access Response abbreviates Msg2 below as) to terminal at down direction.The main effect of Msg2 is that Msg1 is confirmed, to terminal feedback timing adjustment information, and is the Msg3 dynamic assignment ascending resource of later step.The delivery time of Msg2 is by the network dynamic dispatching.Msg2 at a plurality of terminals may be incorporated in back transmission together.The duration of the required downlink resource of Msg2 is 1 TTI, i.e. a subframe.

Step 203: terminal receives the Msg2 that belongs to self, be accidental access response after, in the ascending resource of Msg2 indication, carry out uplink scheduling transmission (Scheduled Transmission abbreviates Msg3 below as).Can comprise some high-level signalings among the Msg3, connect the information such as unique identification of the request of foundation, terminal as Radio Resource control (RRC, RadioResource Control).The duration of the required ascending resource of Msg3 is 1 TTI, i.e. subframe.

Embodiment

Among the present invention, network sends the accidental access response that carries the resource distribution location indication of setting form to terminal, and terminal is determined the ascending resource position according to setting form by the resource distribution location indication, carries out uplink on this ascending resource position.

Fig. 4 is the competitive figure of access process at random among the present invention, and as shown in Figure 4, the competitive processing procedure that inserts at random may further comprise the steps:

Step 401 is identical with step 201.

Step 402: after network is received random access leader sequence, be terminal dynamic assignment ascending resource, send accidental access response, be Msg2 to terminal at down direction.Carry the resource distribution location indication of setting form among the Msg2.The delivery time of Msg2 is by the network dynamic dispatching.Msg2 at a plurality of terminals may be incorporated in back transmission together.The duration of the required downlink resource of Msg2 is 1 TTI, i.e. a subframe.

Step 404 is identical with step 204.

Among the present invention,, make terminal can clearly be informed in the subframe position at Msg3 place in the competitive random access procedure by modes such as system's regulation, system information indication or explicit signaling notices.Difference along with implementations such as system's regulation, system information or explicit signaling notices, the form of expression of the resource distribution location indication of setting form is also inequality, and, it is also inequality that terminal is obtained the processing of ascending resource position, described in detail at the implementation of different situations respectively below.

Implementation one

Network with the offset information of this subframe and Msg2 place subframe, is carried at the form of introns number of frames and is transferred to terminal among the Msg2 after the selected subframe for Msg3.After terminal is received Msg2, determine the subframe position at Msg3 place, promptly determine the ascending resource position according to the introns number of frames of carrying among the subframe position at Msg2 place and the Msg2.The introns number of frames can be introns number of frames actual value, also can be introns number of frames reference value, also can be interval sub-frame of uplink quantity actual value, also can be interval sub-frame of uplink quantity reference value.

A kind of processing mode is that the introns number of frames is an introns number of frames actual value.As shown in Figure 5, the subframe position at Msg2 place is the subframe 0 of field #n+1, network is that the subframe position at terminal distribution Msg3 place is the subframe 2 of field #n+2,8 subframes in interval between the two, therefore the network introns number of frames actual value of carrying in Msg2 is 8, uses 3 bit informations to represent.After terminal was received Msg2,8 subframes at interval in subframe 0 back of the subframe position field #n+1 at Msg2 place were the subframe 2 of the subframe position field #n+2 at Msg3 place.

Another kind of processing mode is that the introns number of frames is an introns number of frames reference value.Under certain system configuration, always can determine introns number of frames minimum value between the subframe at Msg2 and Msg3 place.Therefore, introns number of frames actual value is necessarily more than or equal to introns number of frames minimum value, therefore can be by the mode of system's regulation or system information indication, introns number of frames minimum value is notified to terminal, at this moment, the difference that only need carry introns number of frames actual value and introns number of frames minimum value in Msg2 gets final product.Above-described system configuration can refer to parameters such as radius of society, uplink and downlink timeslot configuration, PRACH configuration, network processes time delay, terminal processes time delay, propagation delay time.By this processing mode, can reduce the information content of required transmission, reduce and optimize signaling consumption.As shown in Figure 5, according to network processes time delay, terminal processes time delay, it is 6 that introns number of frames minimum value is set, 8 subframes in interval between the subframe position at the subframe position at Msg2 place and Msg3 place, at this moment, network only needs the difference 8-6=2 that carries introns number of frames actual value and introns number of frames minimum value in Msg2 to get final product, and uses 1 bit information can finish indication, compare with a last processing mode, saved 2 bit informations.

It is that the introns number of frames is interval sub-frame of uplink quantity actual value that a kind of processing mode is arranged again.For tdd mode, because some subframes are fixed for downlink transfer in the frame structure, other subframes are fixed for uplink, and Msg3 must be positioned at sub-frame of uplink, therefore, subframe at interval is defined as sub-frame of uplink at interval, only considers sub-frame of uplink at interval when determining introns number of frames actual value, only determine that promptly sub-frame of uplink quantity actual value gets final product at interval.As shown in Figure 5,4 sub-frame of uplink in interval between the subframe position at the subframe position at Msg2 place and Msg3 place, network only needs to carry sub-frame of uplink quantity actual value 4 at interval in Msg2, use 2 bit informations to represent to finish indication, compare with the implementation of indicating, saved 1 bit information by introns number of frames actual value.

Also having a kind of processing mode is that the introns number of frames is interval sub-frame of uplink quantity reference value.For tdd mode, some subframes are fixed for downlink transfer in the frame structure, and other subframes are fixed for uplink.Under certain system configuration, always can determine sub-frame of uplink quantity minimum value at interval between Msg2 and the Msg3.Therefore, sub-frame of uplink quantity actual value is necessarily more than or equal to interval sub-frame of uplink quantity minimum value at interval, therefore can be by the mode of system's regulation or system information indication, sub-frame of uplink quantity minimum value is notified to terminal at interval, at this moment, only need carry at interval sub-frame of uplink quantity actual value in Msg2 gets final product with the difference of sub-frame of uplink quantity minimum value at interval.Above-described system configuration can refer to parameters such as radius of society, uplink and downlink timeslot configuration, PRACH configuration, network processes time delay, terminal processes time delay, propagation delay time.

Implementation two

After network is the selected subframe of the Msg3 of terminal, be carried among the Msg2 with the notice terminal with the frame number of Msg3 place subframe position and corresponding to the numbering of the subframe in the frame of frame number.After terminal is received Msg2, can know the subframe position that Msg3 should the place by the frame number of carrying among the Msg2 and subframe numbering.Frame number wherein can adopt absolute numbering form to provide, and also can adopt the relativity shift form to provide, for example, and the next frame of the frame at Msg2 place, Msg2 place frame, the next frame of Msg2 place frame, or the like.Described frame is specially radio frames in the frame structure Class1, be specially field in frame structure type 2.As shown in Figure 5, network needs to carry two category informations in the Msg2 that terminal sends: the field numbering of the subframe place field at Msg3 place and this subframe subframe numbering in corresponding field.Wherein, if the field numbering adopts absolute numbering form, then field is numbered field #n+2, and the subframe in the field is numbered subframe 2; If the field numbering adopts the relativity shift form, then the field numbering can be 1, shows it is the next frame of Msg2 place frame, and the subframe numbering in the field still is a subframe 2.

In addition, the frame position that the frame position at Msg2 place and Msg3 place can be set is relative fixed always, for example, Msg3 place field must be the field at Msg2 place, perhaps, Msg3 place field must be the next field of Msg2 place field, or the like, at this moment, mode by system's regulation or system information indication is notified to terminal with the relative fixed frame position, at this moment, reach the field numbering of Msg3 place field is carried out the implicit expression purpose of indicating, in Msg2, only need carry the subframe numbering in the field of Msg3 place.After terminal is received Msg2,, determine the subframe position of Msg3 in respective frame according to the subframe numbering then according to the frame that the frame position and the relative fixed frame position at Msg2 place are determined the Msg3 place.

For various implementations described above, the back sends because the Msg2 of a plurality of terminals may be incorporated in together, therefore when the subframe position information at the Msg3 place of a plurality of terminals is identical, can merge the back transmission.

System provided by the invention comprises: network and terminal, and wherein, network is used for carrying the resource distribution location indicating concurrent of setting form at accidental access response and send; Terminal is used for determining the ascending resource position according to setting form by the resource distribution location indication, carries out uplink on this ascending resource position.
