Description
Technical field
The present invention relates to digital communicating field, relate more specifically to a kind of launching technique of controlling signaling and measurement pilot frequency.
Background technology
At 3GPP Long Term Evolution (Long Term Evolution, abbreviation LTE) in the system, the emission of uplink control signal is unit with the subframe, and subframe is separated into two parts in time, distributes different frequency resources to realize frequency hopping in the subframe by the first to subframe with second portion.Concerning any communication system, 1/ layer of 2 control of layer signaling retransmits and all is very important scheduling, link circuit self-adapting, the mixing that depends on channel.In the transmission of LTE upstream control signaling, it is defeated to require it to upload a subframe, and carries out frequency hopping in the subframe.The transmission form of 1/ layer of 2 signaling of its layer has two kinds:
(1) signaling of transmitting simultaneously with data, this signaling and data are time division multiplexing on same running time-frequency resource.
(2) with data not simultaneously the transmission signaling; mainly be that ack/nack is replied (Acknowledged/Non-acknowledged; be called for short ACK/NACK) and channel quality indication (Channel Quality Indication; be called for short CQI) signaling, this signaling is only transmitted on the Resource Block of both sides near boundary belt up and down in bandwidth.Each user's ACK/NACK and CQI are mapped to permanent width of cloth zero correlation (the Constant Amplitude ZeroAuto-correlation Code on the frequency domain, abbreviation CAZAC) certain cyclic shift of sequence, ACK/NACK also carries out the piece expansion of orthogonal code in time to realize multi-user multiplexing (as shown in Figure 1).
Simultaneously, in order to measure channel situation, need cycle emission measurement pilot tone (be measuring reference signals Sounding Reference Signal, be called for short SRS), each user's SRS takies one long (Long Block is called for short LB) of a subframe when launching.When not having user data transmission, this user is emission control signaling and SRS simultaneously.CQI is a periodic transfer, can guarantee that CQI and SRS can not transmit simultaneously in a subframe by simple scheduling arrangement.But the ACK/NACK signaling happens suddenly at random, so ACK/NACK and SRS can occur simultaneously in the situation of a subframe transmission.
To the situation that ACK/NACK and SRS transmit in a subframe simultaneously, because SRS has taken a LB, transferring ACK/NACK data can be destroyed single-carrier property simultaneously on this LB, thereby peak-to-average force ratio is increased.If the transmission of restriction SRS on this LB then can impact power control, data dispatch etc., make data throughout descend.
In existing a kind of method, as shown in Figures 2 and 3, keep a LB in the subframe all the time and be used as the SRS transmission, SRS takies the whole system bandwidth.As shown in Figures 2 and 3, ACK represents the ack msg transmission, and RS represents the reference signal of demodulation ack msg, and SRS represents measurement pilot frequency.In Fig. 2 and 3, first LB is used for the SRS transmission, takies whole bandwidth; All LB that do not have shade to fill are used for one group of user ACK signaling transmission, and all LB that have shade to fill are used for the transmission of another group user ACK signaling.The difference of Fig. 2 and Fig. 3 is, the number difference of demodulation ACK reference signal, but usefulness all is to keep the method that a LB does not transmit ACK in the subframe.The benefit of this method is to make the user who launches SRS and ACK/NACK control signaling simultaneously keep the characteristic of single carrier, and can measure the whole system bandwidth.But this launching technique has two shortcomings: 1) also do not use LB of reservation to be used as the structure of SRS if do not send the user of SRS, the user who does not then send SRS has reduced available data transmission resources, and performance can descend to some extent because sending the user of SRS.2) on the LB of other user SRS, do not carry out the ACK/NAK transmission if do not send the user of SRS, then between SRS and ACK/NAK transmission, can introduce and disturb.
In existing another method, as shown in Figure 4 and Figure 5, the user uses and keeps the structure that a LB is used as SRS, and SRS does not take the bandwidth of control signaling simultaneously.Fig. 4 is that the user who does not send SRS launches the structural representation of ACK signaling.Fig. 5 is when transmitting SRS, the control signaling of Samsung suggestion and the structural representation of SRS multiplex mode.Wherein, ACK represents the ack msg transmission, and RS represents the reference signal of demodulation ack msg, and SRS represents measurement pilot frequency.Launch SRS among first LB in Fig. 5, SRS only takies the bandwidth of transfer of data, can not launch on the control signal resource, and other LB is used for the transmission of ACK signaling.This method also can the bonding carrier characteristics, but two shortcomings are arranged: 1) multiplexing on same resource with the user who sends SRS if do not send out the user of SRS, because the difference of emitting structural, the orthogonal code length difference of both piece expansions, can not keep orthogonality, can bring interference each other, especially to the user of same loop displacement is arranged at frequency domain, interference ratio each other is bigger; 2) SRS can not launch on the control signalling bandwidth, therefore can not measure the channel situation on this bandwidth.
Therefore, be necessary the radiation pattern of control signaling and measurement pilot frequency is improved.
Summary of the invention
