Description
Technical field
The present invention relates to the communications field, in particular to a kind of star map mapping method of physical control channel of digital communication system.
Background technology
At present, at LTE (Long Term Evolution, Long Term Evolution) stipulates in the system, as UE (User Equipment, when subscriber equipment) not having upstream data to send, on fixing running time-frequency resource, send Physical Uplink Control Channel (Physical Uplink ControlChannel, PUCCH).As shown in Figure 1, a Physical Uplink Control Channel, on frequency domain, account for a Resource Block (Resource Block, RB), a Resource Block takies 12 subcarriers, continue two time slots subframe i.e. 1 millisecond (ms) just on the time domain, the difference of the Cyclic Prefix that uses according to current subframe, included symbolic number is different.In addition, control channel carries out frequency hopping on two time slots, to obtain the frequency diversity gain.The Physical Uplink Control Channel of each UE is by code division multiplexing in the sub-district, because UE number that can be multiplexing on Resource Block is limited, when the UE that needs to send simultaneously Physical Uplink Control Channel in the sub-district surpasses the multiplexing number of users of Resource Block institute energy, can open up a Resource Block again, just divide and Physical Uplink Control Channel multiplexing that mode that frequency division combines realizes each UE in the sub-district by sign indicating number.
In the current LTE system, Physical Uplink Control Channel can be supported multiple upstream control signaling, comprise ack/nack response message (ACK/NACK), CQI (Channel Quality Indicator, CQI), dispatch request (Scheduling Request, SR), and their combinations of sending simultaneously, wherein ACK/NACK and SR adopt control channel form 1 to send, and CQI adopts control channel form 2 to send.Below concise and to the point introduce various Physical Uplink Control Channel forms 2.
As shown in Figure 2, CQI information via coding obtains 20 coded-bits, modulation obtains 10 modulation symbol S0～S9 through QPSK then, each modulation symbol carries out spread spectrum on frequency domain, wherein frequency expansion sequence is that length is 12 CAZAC (Constant Amplitude ZeroAuto Correlation, the permanent width of cloth zero auto-correlation) sequence, the information symbol that is mapped to control channel form 2 correspondences as shown in Figure 2 then gets on (wherein
The expression information symbol
The expression frequency pilot sign is a reference signal), the effect of reference signal is identical with ACK/NACK's, and carrying out spreading factor at frequency domain is 12 CAZAC sequence spread spectrum, and reference signal is formed the signal that a time slot will send with the CQI information symbol at last.Therefore, in a Resource Block, the UE number that can multiplexingly send CQI is simultaneously decided by the number of the cyclic shift amount that allows available CAZAC sequence.Usually, the cyclic shift amount CS of the CAZAC sequence that can use with channel of CQI information represents.
When UE need send ACK/NACK and CQI simultaneously in a subframe, the extended format 2a or the 2b of UE using form 2 sent.Form 2a or the 2b send mode on signal code is identical with form 2, is used for carrying CQI.The ACK signaling bear uses BPSK (1-bit ACK) or QPSK (2-bit ACK) to be modulated to second frequency pilot sign of each time slot respectively on second frequency pilot sign of each time slot of form 2a or 2b.
In the existing systems, modulation system is to adopt BPSK shown in Figure 3 or QPSK mode shown in Figure 4.Modulation symbol under the BPSK mode has only a bit, can represent two states.Planisphere position-1 expression the ACK of Fig. 3; Planisphere position 1 expression NACK.Modulation symbol under the QPSK mode has two bits, can feed back four kinds of states.The planisphere of Fig. 4-1, j ,-j, 1, difference corresponding A CK/ACK (being ACK and ACK), ACK/NACK (being ACK and NACK), NACK/ACK (being NACK and ACK), NACK/NACK (being NACK and NACK).That is, the position 1 expression DTX (Discontinue Transmission, discontinuous transmission) under form 2, the position 1 expression DTX+NACK under the form 2a, and the position 1 expression DTX+NACK/NACK under the form 2b.
In realizing process of the present invention, the inventor finds to receive the PUCCH side can not distinguish DTX under the form 2, the DTX+NACK under the form 2a, and the DTX+NACK/NACK under the form 2b from PUCCH itself.If UE has lost the downlink resource of distributing to it, and only send CQI form 2 feedback, do not send ACK (being DTX), NodeB receives PUCCH then can think this signaling by mistake DTX+NACK under the form 2a, the perhaps DTX+NACK/NACK under the form 2b.In this case, NodeB is the allocation of downlink resource once more, and supposes that UE can carry out soft merging to the resource of the resource of last sub-distribution and sub-distribution again, thereby causes unnecessary capacitance loss.
