Description

The method for mapping resource and device of ascending physical signal control channel

Technical field

The present invention relates to the communications fields, and particularly, design the method for mapping resource and device of a kind of ascending physical signal control channel.

Background technique

In long term evolution (Long Term Evolution, LTE) in system time division duplex (TimeDivision Duplex, TDD) mode, frame structure (also known as the second class frame structure for using, that is, frame structure type2) as shown in Figure 1.

As shown in Figure 1, the radio frames of a 10ms (307200Ts, 1ms=30720Ts) are divided into two fields, each half frame length 5ms (153600Ts) in this frame structure.Each field includes the subframe that 5 length are 1ms.

The effect of each subframe is as shown in table 1, and in table 1, D represents the downlink subframe for being used for transmission downlink signal；U represents the sub-frame of uplink for being used for transmission uplink signal；In addition, a upstream or downstream subframe is divided into the time slot of 2 0.5ms again；S represents special subframe, includes three special time slots, i.e.; descending pilot frequency time slot (Downlink Pilot Time Slot; DwPTS), protection interval (Guard Period, GP) and uplink pilot time slot (UplinkPilot Time Slot, UpPTS).In systems in practice, uplink and downlink formulatory indices can give terminal (for example, mobile phone) by the notice that broadcasts the message.

In description herein, the even timeslots of radio frames can be equal to first time slot of a subframe, and the odd numbered slots of radio frames can be equal to second time slot of a subframe.

Table 1

In frequency division duplex (Frequency Division Duplex, FDD) mode of LTE system, the frame structure (also known as first kind frame structure, that is, frame structure type1) of use is as shown in Figure 2.

As shown in Fig. 2, the radio frames of a 10ms are divided into the time slot of 20 0.5ms, 2 adjacent time slots form the subframe that a length is 1ms, that is, subframe i is made of time slot 2i and 2i+1, wherein i=0,1 ..., 9.Also, in the fdd mode, 10 subframes are all used for the transmission of upstream or downstream signal, are distinguished between uplink and downlink by different frequency bands.

LTE system Physical Random Access Channel (Physical Random Access Channel, referred to as PRACH can also be referred to as random access chance (random accessopportunity) or random access resource (random access resource).The corresponding random access preamble (random access preamble) of one accidental channel, it is leading to be made of cyclic prefix (Cyclic Prefix, CP) and Sequence two parts, as shown in figure 3, Different leading formats (preambleformat) mean different CP and/or Sequence length.The preambleformat type that LTE system tdd mode is supported at present is as shown in table 2.

 

Leading format	TCP	TSEQ
			0	3168·Ts	24576·T s
1	21024·Ts	24576·T s
			2	6240·T s	2·24576·T s
3	21024·T s	2·24576·Ts
			4 (only frame structure type 2)	448·Ts	4096·Ts

Table 2

In the leading format shown in table 2, format0~3 preamble can transmit in generic uplink subframe, and preamble format4 can be transmitted in UpPTS, and specific transmission mode is as follows: preamble format0 is transmitted in a generic uplink subframe；Preambleformat1,2 are transmitted in two generic uplink subframes；Preamble format3 is transmitted in three generic uplink subframes；Preamble format4 transmits (initial position shifts to an earlier date at the end of UpPTS to be sent on the position 5158Ts) in UpPTS.

Resource allocation in LTE system is with resource block (Resource Block, it RB) is unit, one RB occupies 12 resource element (Resource Element on frequency domain, referred to as RE, wherein, one RE occupies a SC-FDMA symbol in the time domain), one RB occupies a time slot in the time domain, i.e., one RB occupies 7 or 6 single-carrier frequency division multiple access (Single Carrier-Frequency Division MultipleAccess in the time domain, SC-FDMA) symbol, that is, one RB is in general cyclic prefix (Normal Cyclic Prefix, Normal CP) item Under part, 7 SC-FDMA symbols are occupied, under conditions of extended cyclic prefix (Extended Cyclic Prefix, Extended CP), occupy 6 SC-FDMA symbols.

Fig. 4 is the schematic diagram of the resource block and resource units relationship according to the relevant technologies, as shown in figure 4, being if defining the corresponding RB sum of up-link bandwidth under conditions of common CP

Then the index of RB is 0,1 ...,

In frequency domain, a random access preamble accounts for bandwidth corresponding to 6 RB, i.e. 72 RE, and the bandwidth of each RE is 15kHz.The identical PRACH channel of time-domain position is distinguished by frequency domain.

On frequency domain, generic uplink subframe can transmit PRACH channel, Physical Shared Channel (Physical uplink shared channel, PUSCH), Physical Uplink Control Channel (Physical uplink control channel, PUCCH), the physical channels/signal such as detection reference signal (Soundingreference signal, SRS).UpPTS packet can transmit the PRACH channel that SRS signal and leading format are 4.

PUCCH channel format can be divided into two major classes, and totally 6 kinds: the first kind includes 3 kinds of formats, i.e. format1,1a, 1b, and the second class includes 3 kinds of formats, i.e. format2,2a, 2b.First kind PUCCH is used for transmission SR (scheduling request, scheduling request) and correct response (Acknowledgement, ACK)/wrong responses (NegativeAcknowledgement, NACK) signaling, wherein, format1, which is used for transmission SR, format1a and is used for transmission ACK/NACK, format1b of single codeword stream, is used for transmission the ACK/NACK of double streams of code words.Multiple first kind PUCCH channels (or being PUCCH resource) are multiplexed in a RB by way of code point.

On the other hand, second class PUCCH is mainly used for transmission channel quality instruction (ChannelQuality Indicator, CQI), wherein, format2 only transmits CQI, format2a is used for the ACK/NACK of simultaneous transmission CQI and single codeword stream, ACK/NACK of the format2b for simultaneous transmission CQI and double streams of code words.Multiple second class PUCCH channels are also to be multiplexed in a RB by way of code point.The quantity (Control ChannelElement, CCE) of RB number and down control channel unit first kind PUCCH shared in a time slot is related, is dynamic change；Second class PUCCH is in a time slot Interior shared RB number is notified by broadcast channel to all UE in cell, is semi-static preparation.In addition, LTE system also defines mixing RB, the concurrent multiplexing first kind and the second class PUCCH channel in order to avoid the waste of code resource.It can be prepared in system with the presence or absence of mixing RB, and in a time slot, be up to one mixing RB.Before carrying out PUCCH resource to physics RB mapping, PUCCH resource is mapped on logic RB index first, then logic RB index is mapped on the physics RB of each time slot again.The mapping method of first kind PUCCH to logic RB index is shown below:

Wherein,

It is indexed for PUCCH resource,

For RB number shared by the second class PUCCH channel,

The cyclic shift amount that first kind PUCCH is distributed in mixing RB,

For the step length of cyclic shift of first kind PUCCH,

For the quantity of RE of the RB shared by frequency domain.Second class PUCCH resource is to the mapping method that logic indexes

Wherein

For the second class PUCCH resource index.Above-mentioned mapping method makes the logic of first kind PUCCH index the index less than the second class PUCCH.When there is mixing RB, the logic index for mixing RB is located between first kind PUCCH logic index and the second class PUCCH logic index.Wherein, m is PUCCH logic RB index.

In terms of PUCCH logic RB indexes the mapping of physics RB index, current method is as follows:

In first time slot (that is, even timeslots) of a subframe, by the logic RB index of even number on Sequential Mapping from small to large to physics RB index, physics RB index is from 0 Start to be increased continuously；By the logic RB index of odd number on Sequential Mapping from small to large to physics RB index, physics RB index from

Start continuously to successively decrease；

In second time slot (that is, odd numbered slots) of a subframe, by the logic RB index of even number on Sequential Mapping from small to large to physics RB index, physics RB index from

Start continuously to successively decrease；The logic RB index of odd number is sequentially mapped on the physics RB index being increased continuously since 0 with sequence from small to large.

The physical resource index mapped by this method is as shown in Figure 5.

However, therefore the frequency domain position that the mapping method that this PUCCH channel logic RB indexes physics RB index does not account for PRACH channel will cause the interference of PRACH channel Yu PUCCH channel.Currently, not yet proposing to be able to solve the interference indexed PUCCH channel logic RB between PRACH channel and PUCCH channel caused by the mapping of physics RB index.
