Description

The identification method of downlink component carrier and a kind of base station in a kind of random access procedure
Technical field
The present invention relates to moving communicating field, particularly a kind of in the LTE-A system random access process identification method and a kind of base station of downlink component carrier.
Background technology
Insert at random (Random Access) be terminal begin with network service before a kind of access procedure.As shown in Figure 1, LTE (Long Term Evolution, Long Term Evolution) random access procedure of system is gone up to the base station at Physical Random Access Channel (Physical Random Access Channel is called for short PRACH) by terminal earlier and is sent random access guiding (random access preamble).After the base station receives the random access guiding that terminal sends, utilize the sequence that wherein comprises, calculate Timing Advance, and be used for next step channel transmitted resource for this terminal distribution (to be called uplink scheduling authorization, UL grant) and interim C-RNTI (Cell Radio Network Temporary Identifier, Cell Radio Network Temporary Identifier/Identity, Cell-RNTI number).Random access guiding identification number (Random Access Preamble Identifier), Timing Advance, signal channel resource allocation information and interim C-RNTI etc. send to this terminal through Physical Downlink Shared Channel, are called accidental access response (random access response).Terminal is after receiving accidental access response, on the uplink channel resources of correspondence, send (the First scheduled UL transmission of dispatching uplink transmission first according to the signal channel resource allocation information UL grant in the accidental access response, be abbreviated as scheduledtransmission, be called Message 3 again, be abbreviated as Msg.3), and according to the interim C-RNTI in the accidental access response to the Msg.3 scrambling.Msg.3 includes different information according to the incident that triggers this random access procedure is different, comprises such as RRC connection request (RRC Connection Request), C-RNTI of terminal or the like.The base station receives that the competition that inserts at random by its content feed behind the Msg.3 solves (Contention Resolution) to terminal, is called Message 4, is abbreviated as Msg.4.
Resource allocation in the LTE system is with Physical Resource Block (Physical Resource Block, PRB, or abbreviate Resource Block as, Resource Block) is unit, a PRB accounts for 12 subcarrier (subcarrier on frequency domain, or be called Resource Element, abbreviate RE as, each subcarrier is 15kHz), on time domain, account for a time slot, promptly on time domain, occupy 7 regular circulation prefix (Normal cyclicprefix, abbreviate Normal CP as) or 6 extended cyclic prefix (Extended cyclic prefix, Extended CP) SC-FDMA (Single Carrier Frequency Division Multiple Access, single carrier frequency division is multiplexing) symbol.If up-link bandwidth corresponding RB on frequency domain adds up to N RB UL, then the index of RB be 0,1 ..., N RB UL-1, the index of RE is 0,1 ..., N RB ULM SC RB-1, wherein, N SC RBIt is a RB pairing sub-carrier number on frequency domain.With the regular circulation prefix is example, and the structure of PRB as shown in Figure 2.
In the LTE system, the Physical Random Access Channel configuration parameter includes, but is not limited to article one of (1) Physical Random Access Channel can be with the logic index of root sequence; (2) frequency domain initial position; (3) configuration index of Physical Random Access Channel; (4) cyclic shift amount; (5) cyclic shift restriction sign.Introduce the implication of these parameters below respectively.
In the LTE system, Physical Random Access Channel uses the cyclically shifted sequences of Zadoff-Chu (being called for short ZC) sequence as leading (preamble), these ZC sequences are called the root sequence again, these cyclically shifted sequences are called zero correlation zone (Zero Correlation Zone is called for short ZCZ) sequence again.At first carry out down-going synchronous after the starting up of terminal, begin to detect broadcast channel afterwards.The base station is by the logic index of the operable article one ZC sequence of broadcast channel notice terminal this cellular PRACH channel and the step-length (being the cyclic shift amount) of cyclic shift, terminal obtains the physics index of this sequence according to certain mapping ruler from article one root sequential logic index, generates available ZCZ sequence according to cyclic shift amount and certain " cyclic shift restriction rule " then.These cyclic shift restriction rules are enabled by cyclic shift restriction sign.(in the LTE system, T=64), the automatic increasing sequence logic of terminal index then utilizes next bar ZC sequence to continue to generate ZCZ sequence, till the sum of ZCZ sequence is more than or equal to above-mentioned threshold value if the quantity of ZCZ sequence is less than threshold T.At last, terminal selects one to send as random access guiding (hereinafter to be referred as leading) in the available ZCZ sequence of all generations at random.
In the LTE system, the PRACH channel is at the index n of shared first Physical Resource Block (PRB) of frequency domain PRBoffset RA(being frequency domain initial position) by base station notice terminal, span is by signaling 0 ≤ n PRBoffset RA ≤ N RB UL - 6
In the LTE system, the configuration index of Physical Random Access Channel has 64 kinds.The configuration of fdd mode is different with the configuration of tdd mode, as shown in Table 1 and Table 2.
