Abstract

The invention discloses a resource distribution method of a physical random access passage, comprising the steps as follows: when resource is distributed to PRACH, the frequency domain resource of each PRACH is alternatively mapped to two sides of the initial position and the frequency domain resource of each PRACH is ensured to be continuous by taking a certain initial position on the frequency domain as the center for one or more PRACH with the same time domain positions. The method of the invention can ensure that the PRACH and PUCCH are not mutually interfered and that the resource of the PUSCH is not cut as multi-section; furthermore, the maximum bandwidth of PUCCH is not necessary to be taken into account.

Description

A kind of resource allocation methods of Physical Random Access Channel
Technical field
The present invention relates to the communications field, be specifically related to a kind of resource allocation methods of Physical Random Access Channel.
Background technology
The frame structure (being called second type of frame structure again, i.e. frame structure type 2) of LTE (Long Term Evolution) system TDD (Time Division Duplex, time division duplex) pattern is as shown in Figure 1.In this frame structure, (307200Ts, radio frames 1ms=30720Ts) is divided into two fields to a 10ms, the long 5ms of each field (153600Ts).The subframe that it is 1ms that each field comprises 5 length.The effect of each subframe is as shown in table 1, and wherein the D representative is used for the descending sub frame of transmission of downlink signal.The U representative is used to transmit the sub-frame of uplink of upward signal.In addition, upstream or downstream subframe is divided into the time slot of 2 0.5ms again.S represents special subframe, comprises three special time slots, i.e. DwPTS (Downlink PilotTime Slot, descending pilot frequency time slot), GP (Guard Period, protection at interval) and UpPTS (UplinkPilot Time Slot, uplink pilot time slot).In real system, the uplink and downlink configuration index can be notified to mobile phone through broadcast.
Table 1 uplink and downlink sub-frame configuration
Figure G2008101354440D00011
The frame structure (being called first kind frame structure again, i.e. frame structure type 1) of the FDD of LTE system (Frequency Divsion Duplex, FDD) pattern is as shown in Figure 2.The radio frames of a 10ms is divided into the time slot of 20 0.5ms, and adjacent 2 time slots are formed the subframe that length is 1ms, and promptly subframe i is made up of time slot 2i and 2i+1, i=0 wherein, and 1 ..., 9.Under fdd mode, 10 sub-frame all are used for the transmission of upstream or downstream signal, distinguish through different frequency bands between the uplink and downlink.
The structure of LTE system physical accidental access channel (PRACH, Physical Random Access Channel, or be called and insert chance at random, i.e. random access opportunity) is as shown in Figure 3.Preamble (leading) is made up of cyclic prefix CP and sequence Sequence two parts, and different preambleformat (leading form) means different CP and/or Sequence length.The preamble format kind of LTE system TDD mode support at present is as shown in table 2.

In the above-mentioned leading form, transmit in common sub-frame of uplink preamble format0～3, and preambleformat4 transmits in UpPTS.
Preamble format 0 transmits in a common sub-frame of uplink;
Preamble format 1,2 transmits in two common sub-frame of uplink;
Preamble format 3 transmits in three common sub-frame of uplink;
Preamble format 4 transmits (original position is sent on the 5158Ts position at the place, end of UpPTS in advance) in UpPTS
Resource allocation in the LTE system is a unit with RB (Resource Block, Resource Block), and a RB accounts for 12 RE (Resource Element on frequency domain; Resource element; On time domain, account for an OFDM symbol), on time domain, account for a time slot, i.e. 7 (common CP; Normal cyclic prefix) or 6 (expansion CP, Extended cyclic prefix) SC-OFDM symbols.If the corresponding RB of definition up-link bandwidth adds up to N RB UL, then the index of RB is 0,1 ..., N RB UL-1, as shown in Figure 4.
At frequency domain, a PRACH channel accounts for 6 pairing bandwidth of RB, i.e. 72 RE, and the bandwidth of each RE is 15kHz.The PRACH channel that time-domain position is identical is distinguished through frequency domain.
On frequency domain; Common sub-frame of uplink can transmit PRACH channel, Physical Shared Channel (PUSCH; Physical uplink shared channel), Physical Uplink Control Channel (PUCCH; Physical uplinkcontrol channel), detection reference signal physical channel/signals such as (SRS, Sounding reference signal).Can the transmitting SRS signal in the UpPTS and leading form be 4 PRACH channel.
The PUCCH channel format can be divided into two big types, and totally 6 kinds: the first kind comprises 3 kinds of forms, i.e. format1,1a, 1b, and second type comprises 3 kinds of forms, i.e. format 2,2a, 2b.First kind PUCCH is used to transmit SR (dispatch request; Scheduling request) and ACK (Acknowledgement)/NACK (Negative Acknowledgement) signaling; Wherein, format 1 is used to transmit the ACK/NACK that ACK/NACK, format 1b that SR, format la be used to transmit single codeword stream are used to transmit two streams of code words.Second type of PUCCH is mainly used in transmission CQI (Channel Quality Indicator); Wherein 2 of format transmit CQI; Format 2a is used for transmitting simultaneously the ACK/NACK of CQI and single codeword stream, and format 2b is used for transmitting simultaneously the ACK/NACK of CQI and two streams of code words.First kind PUCCH quantity (CCE, Control Channel Element) of shared RB number and down control channel unit in a time slot is relevant, is dynamic change; Second type of PUCCH shared RB number in a time slot notifies to all UE in the sub-district through broadcast channel, is semi-static preparation.In addition, for fear of the waste of sign indicating number resource, the LTE system has also defined mixing RB, the multiplexing first kind and second type of PUCCH channel.Whether exist mixing RB to prepare in the system, and in a time slot, have one to mix RB at most.In common sub-frame of uplink; The channel architecture of PUCCH is as shown in Figure 5; On frequency domain, the shared RB of PUCCH is distributed in the two ends of the whole frequency domain of system, just lays respectively at the upper sideband (being several maximum RB of index) and the lower sideband (being several minimum RB of index) of frequency domain.
At present, in common sub-frame of uplink, the frequency domain mapping method of PRACH channel is for to shine upon from both sides to the centre, and mapping method is shown in formula (1).

Wherein, n PRB offset RAFrequency domain initial position for the PRACH channel; N RB ULBe the corresponding RB number altogether of up-link bandwidth preparation; f RAFrequency domain index for the identical PRACH channel of time-domain position;

Expression rounds downwards.n PRB offset RAValue is related to the position of PRACH channel on frequency domain, produces the interference between PRACH and the PUCCH if design improper meeting, or makes the PUSCH resource be divided into multistage, increases the complexity of scheduling.
Because the frequency domain position of PUCCH is at the two ends of whole frequency band, this requires the PRACH and then maximum bandwidth of PUCCH transmission on frequency domain, and is as shown in Figure 6.Therefore, in order to guarantee the performance of this PRACH channel of formula (1) frequency domain mapping method, requirement can be predicted the maximum transmission bandwidth of PUCCH more accurately.And since the quantity random time of first kind PUCCH channel change, cause the needed RB number of PUCCH also random time change, make the maximum bandwidth of the predicting PUCCH accurately comparison difficulty that becomes.
