Background technology
Concerning communication system, the control signaling that layer is 1/ layer 2 retransmits and all is very important scheduling, link circuit self-adapting, the mixing of the channel that depends on this signaling.The signaling that layer is 1/ layer 2 mainly comprises: the signaling that (1) is relevant with transfer of data, in full reportedly transport format, mixing retransmission information etc.; (2) with the irrelevant signaling of transfer of data, as reply with the dispatch request of channel quality indication (CQI) information, transfer of data etc.
In E-UTRA, the transmission of signal is unit with the subframe.In traditional control signaling and the transfer of data time division multiplexing sending method, subframe of up link comprises 8 data blocks, by 2 SB (Short Block, short data block) and 6 LB (Long Block, the long data piece) forms, as shown in Figure 1, LB1 shown in this figure, in subframe foremost, be used to send and the irrelevant signaling of user data, SB1 and SB2 are used to send public reference signal, the measurement that this reference signal can be used to control the channel estimating of signaling and transfer of data or be used for channel quality.Six long data pieces of LB1～LB6 all are used to send user data or the control signaling relevant with user data, and when not controlling signaling, LB1～LB6 sends user data, and when user data of no use, LB1～LB6 also can be used to control the transmission of signaling.Because when the SB of the LB that sends control signaling and the transmission of reference signals of correspondence receives, the demodulation of control signaling ability, the time-delay of therefore this sending method control signaling is bigger, and the control signaling consumption is less, and hence one can see that with a LB sends control signaling and can cause the serious waste of running time-frequency resource.
In the R1-061794 of 3GPP motion, Qualcomm company has proposed a kind of improved sending method.In this method, a subframe comprises 9 data blocks, form by 4 SB and 5 LB, as shown in Figure 2, the SB1 shown in this figure, in subframe foremost, be used to send and signaling that user data is irrelevant, SB2 is used to send special-purpose reference signal, and this signal is used for the demodulation with the irrelevant control signaling of user data, SB3 and SB4 are used to send public reference signal, and this reference signal is used for the channel estimating of transfer of data or is used for the measurement of channel quality.Five long data pieces of LB1～LB5 all are used to send user data or the control signaling relevant with user data, and when user data of no use, LB1～LB5 also can be used to control the transmission of signaling.And when not controlling signaling, SB1 and SB2 also can send user data.Compare above-mentioned traditional sending method of mentioning, this method can make the demodulation of control signaling carry the time interval of previous SB, but this sending method still has following shortcoming: the one, reduced available data transmission resources, this is because the control signaling has been introduced DRS (Dedicated Reference Signal), and has taken certain data transmission resources; The 2nd, the waste reference signal resource, this is to come transmission of reference signals just can satisfy the needs of channel estimating because need only in a subframe with 2 SB.Therefore just need do further improvement to the send mode of control signaling and reference signal.
