Description
Technical field
The present invention relates to wireless communication field, particularly Physical Random Access Channel (physical randomaccess channel, PRACH) transfer approach of frequency domain original position and device thereof.
Background technology
It is physical layer important technology in the mobile communication that initialization inserts at random, and employing by the Mobile Originated technology of obtaining uplink synchronous and applying for resource allocation, is the first step that the user initiates to communicate by letter after setting up down-going synchronous.
It is that the user is after obtaining down-going synchronous that initialization inserts at random, know the configuration of all available access sequences (preamble sequence) and Physical Random Access Channel in the sub-district by cell broadcast messages, in resource pool, select access sequence to go up then at random and send to obtain the process of uplink synchronous and requests resource allocation at up Physical Random Access Channel (PRACH).After if the base station successfully detects this sequence and is this travelling carriage Resources allocation, travelling carriage is with regard to successful connecting system, otherwise, if make travelling carriage finally can't obtain resource because of certain reason in the access procedure, then access failure is initiated access exploration after travelling carriage is waited for a time at random once more.
Do not obtain uplink synchronous because send the user of PRACH, therefore the moment that arrives base station side is inconsistent with the moment that other upstream datas that obtained users' transmission of uplink synchronous arrive the base station, will destroy the orthogonality between the subcarrier of OFDM like this, and PRACH can cause interference to the signal that carries on the frequency domain that is close to oneself.
In 3GPP LTE standard, the frequency domain original position of PRACH is by high-level signaling dominance notice, and concrete bit number is not determined, and specifically how the signaling indication does not all have to determine.
In 3GPP LTE standard, Physical Uplink Control Channel (Physical uplink control channel, PUCCH) mainly be carrying scheduling application indication (schedule request indicator, SRI), response message (ACK/NACK), and the channel quality indication (channel quality indicator, CQI), wherein PUCCH has format 1/1a/1b, famat 2/2a/2b.
PUCCH format 1: be used for the up transmission dispatch request of terminal;
PUCCH format 1a/1b: be used for the up transmission of terminal ACK/NAK (1 or 2 bit);
PUCCH format 2: be used to send up CQI feedback (coding back 20 bits);
PUCCH format 2a: the ACK/NAK information that is used to send up CQI feedback (coding back 20 bits)+1 bit;
The target error probability requirement of table 1ACK and CQI
| ??Event | ??Target?quality |
| ??ACK?miss?detection(for?DL-SCH) | ??(1e-2) |
| ??DTX?to?ACK?error(for?DL-SCH) | ??(1e-2-1e-1) |
| ??NACK?to?ACK?error(for?DL-SCH) | ??(1e-4-1e-3) |
| ??CQI?block?error?rate | ??(1e-2-1e-1) |
Be easy to find out from table 1, to the performance requirement of ACK (PUCCH format 1a/1b) than CQI (PUCCH format 2/2a/2b) height.
PUCCH adopts the mode of frequency hopping between time slot, transmit on both sides in upstream band, as shown in Figure 1, is the resource mapping graph of the PUCCH in the 3GPP LTE standard, if PRACH next-door neighbour PUCCH format is 1/1a/1b, then PRACH can cause interference to PUCCH format 1/1a/1b.
Existing 3GPP standard code is monitored last symbol that pilot tone (soundingreference symbol, S RS) is in subframe under FDD and TDD situation, all frequency bands except PUCCH can be monitored.In addition, under the TDD situation, SRS can also be positioned at uplink pilot time slot (downlink pilot time slot, UpPTS), do not having to listen to full bandwidth under the situation of PRACH, having under the situation of PRACH, locating the bandwidth outside the PRACH and can monitor.
Notify the frequency domain original position of PRACH at present with 7bits, because the Resource Block of the maximum bandwidth of system (resource block, RB) number is 110,7 bits like this that is to say that with regard to any one RB in the energy indication mechanism bandwidth any in a system bandwidth RB can become the frequency domain original position of PRACH.Like this, this 7bits notice is absolute RB number of frequency domain original position correspondence of PRACH.
Yet, the present inventor finds by analysing in depth: the frequency domain original position of PRACH is notified with 7 bits, has flexibility completely, systematic function do not had benefit, on the contrary, signaling consumption is too big, and if the frequency domain original position of PRACH and PUCCH irrelevant, will can bring very big complexity to the PUSCH burst to scheduler so so.
Summary of the invention
