Description

A kind of sending method of upward signal and subscriber equipment

Technical field

The present invention relates to digital communicating field, particularly relate to 3GPP Long Term Evolution and senior 3GPP Long Term Evolution (Long Term Evolution Advanced is called for short LTE-A), relate in particular to a kind of sending method and subscriber equipment of upward signal.

Background technology

Long Term Evolution (Long Term Evolution, abbreviating LTE as) uplink physical channel of system comprises: Physical Random Access Channel (Physical Random Access Channel, abbreviate PARCH as), Physical Uplink Shared Channel (Physical Uplink Shared Channel, abbreviate PUSCH as) and Physical Uplink Control Channel (Physical Uplink Control Channel abbreviates PUCCH as).Up employing single carrier OFDM (the Orthogonal Frequency Division Multiplexing of LTE, OFDM) technology, reference signal and data are multiplexing together by the mode of TDM (Time Division Multiplexing, time division multiplexing).Uplink reference signals is divided into demodulated reference signal (Demodulation Reference Signal, abbreviate DMRS as) and measuring reference signals (Sounding Reference Signal, abbreviate SRS as), wherein, DMRS is divided into PUCCH and separates and call reference signal and PUSCH and separate and call reference signal, is respectively applied for different Channel Transmission.The main effect of DMRS is coherent detection and the demodulation that is used for the estimation of up channel and base station (abbreviating eNB as) end, and the main effect of SRS is the measurement that is used for up channel, is convenient to eNB and does frequency selective scheduling.

At LTE (Long Term Evolution, Long Term Evolution) in the system, in order to realize and to keep subscriber equipment (User Equipment, abbreviate UE as) and the base station between uplink synchronous, the base station is according to propagation delay time transmitting time lead (the Timing Advance between self and each subscriber equipment, abbreviate TA as) to each subscriber equipment, the Timing Advance that subscriber equipment sends according to the base station in advance or postpone separately uplink opportunity, thereby remedy the propagation delay time of user terminal, make the upward signal of different user devices within the receive window of base station, to arrive the base station to the base station.

LTE-A (LTE Advanced, senior Long Term Evolution) system is the evolution system of future generation of LTE system, and it has introduced the notion of carrier aggregation (Carrier Aggregation).The LTE system bandwidth of described carrier aggregation can be regarded component carrier (Component Carrier) frequency spectrum as, each component carrier also can be called a Serving cell (serving Cell), and just a frequency spectrum can be polymerized by a plurality of component carrier frequency (Serving cell).The resource of a R10UE is to be made of a plurality of Serving cells (component carrier) of frequency domain, and one of them sub-district is called main plot (Primary cell abbreviates PCell as), and all the other sub-districts are called auxilliary sub-district (Secondary cell abbreviates SCell as).

After introducing carrier aggregation technology, subscriber equipment may be simultaneously operated on a plurality of component carriers, and these component carriers can be continuous on frequency band, also can be discontinuous; Can be in the identical frequency band, can also come from different frequency bands.For the discontinuous situation of component carrier, perhaps component carrier comes from the situation of different frequency bands, because each component carrier has different transmission characteristics, the Timing Advance on each component carrier may be different; Even for belonging to identical frequency band and continuous a plurality of component carriers on frequency band, if each component carrier is derived from different Remote Radio Unit (Remote Radio Units, abbreviate RRU as), perhaps cover in order to increase the sub-district, each component carrier is handled via different repeater (repeater) respectively, and then the Timing Advance on each component carrier also may be different.In the LTE system, UE only is operated in that (for TDD mode is a carrier wave on the carrier wave, comprise up, descending a pair of carrier wave for mode of frequency division duplexing, for convenience of description, here abbreviate above-mentioned two kinds of situations as a carrier wave), only need to safeguard the uplink synchronous of a up link, and in carrier aggregation, UE may be simultaneously operated on a plurality of component carriers, and the TA of these component carriers might be different, promptly there are a plurality of Timing Advances (Multiple Timing Advance abbreviates MTA as) simultaneously.

Exist under the scene of MTA, because the TA of different upstream components carrier waves might be different, mean that the signal code of transmitting may not line up on different upstream components carrier waves, the overlapping possibility in signal code front and back on time domain of different upstream components carrier transmission might occur on time domain.But Rel-10 and before in the LTE agreement of version, do not define transmission symbol sending method when overlapping before and after on time domain.

Adopt the several application example that the present invention is further specified below in conjunction with accompanying drawing.

Use example 1

In following application example 1-1～1-5, UE has disposed two up-link carrier CC1 and CC2, and wherein CC1 is PCell, and CC2 is SCell.CC1 belongs to different TA groups with CC2, and wherein CC1 belongs to TA group 1, and CC2 belongs to TA group 2.

Use example 1-1

As shown in Figure 3, in subframe n, CC1 and CC2 need to transmit PUSCH.Because CC1 is different with the TA of CC2, so the PUSCH symbol among the subframe n on the CC1 and the PUSCH symbol among the subframe n on the CC2 have taken place to overlap.TAG represents the TA group among Fig. 3, and is also like this among following each figure.

If this moment, eNB indicated UE by signaling, the PUSCH on CC1 and the CC2 is sent simultaneously, perhaps UE is according to predefined regular 1), the PUSCH on CC1 and the CC2 is sent simultaneously, then UE directly sends the PUSCH on CC1 and the CC2.

Use example 1-2

As shown in Figure 3, in subframe n, CC1 and CC2 need to transmit PUSCH.Because CC1 is different with the TA of CC2, so the PUSCH symbol among the subframe n on the CC1 and the PUSCH symbol among the subframe n on the CC2 have taken place to overlap.And the PUSCH among the CC1 carries UCI, and the PUSCH among the CC2 does not carry UCI.

If this moment, eNB abandoned PUSCH on one of them CC by signaling indication UE according to priority, perhaps UE is according to predefined regular 1) in mode b) abandon PUSCH on one of them CC according to priority, then:

The formulating method of priority is method II when this moment) time, promptly formulate priority according to the carrier wave of carrying PUSCH, because CC1 is PCell, so the PUSCH height on the PUSCH priority ratio CC2 on the CC1, this moment, UE can abandon the PUSCH on the CC2, only sent the PUSCH on the CC1;

The formulating method of priority is method I when this moment) time, promptly formulate priority according to whether carrying UCI, because the carrying of the PUSCH among CC1 UCI, so the PUSCH height on the PUSCH priority ratio CC2 on the CC1, meeting this moment UE abandons the PUSCH on the CC2, only sends the PUSCH on the CC1.

Use example 1-3

As shown in Figure 4, in subframe n, CC1 need transmit PUSCH, and in subframe n+1, CC2 need transmit PUSCH.Because CC1 is different with the TA of CC2, so first symbol of last symbol of the PUSCH among the subframe n on the CC1 and the PUSCH among the subframe n+1 on the CC2 has taken place to overlap.And the PUSCH among the CC1 carries UCI, and the PUSCH among the CC2 does not carry UCI.

If this moment eNB by signaling indication UE according to priority to carrying out rate-matched among one of them PUSCH, leave a blank itself and another overlapping symbol of PUSCH symbol, perhaps UE is according to predefined regular 1) in mode c), according to priority to carrying out rate-matched among one of them PUSCH, leave a blank itself and another overlapping symbol of PUSCH symbol, then:

The formulating method of priority is method I when this moment) time, promptly formulate priority according to whether carrying UCI, because the carrying of the PUSCH among CC1 UCI, so PUSCH height on the PUSCH priority ratio CC2 on the CC1, therefore UE carries out rate-matched to the PUSCH on the CC2, leave a blank first symbol among the PUSCH on the CC2 sends CC1 among the subframe n and other symbols among the PUSCH on the CC2 among the subframe n+1 then;

The formulating method of priority is method II when this moment) time, promptly formulate priority according to the carrier wave of carrying PUSCH, because CC1 is PCell, so PUSCH height on the PUSCH priority ratio CC2 on the CC1, therefore UE carries out rate-matched to the PUSCH on the CC2, leave a blank first symbol among the PUSCH on the CC2 sends CC1 among the subframe n and the PUSCH on the CC2 among the subframe n+1 then;

The formulating method of priority is method III when this moment) time, promptly formulate priority by subframe index, stipulate that the PUSCH of last subframe is higher than the PUSCH of back one subframe, then because the corresponding subframe index of PUSCH on the CC1 is n, and the corresponding subframe index of the PUSCH on the CC2 is n+1, so PUSCH priority height on the PUSCH priority ratio CC2 on the CC1, therefore UE carries out rate-matched to the PUSCH on the CC2, leave a blank first symbol among the PUSCH on the CC2 sends CC1 among the subframe n and the PUSCH on the CC2 among the subframe n+1 then;
