Problems solved by technology

[0006] In the current R10 version of the LTE standard, simultaneous transmission of SRS between CCs, PUSCH and / or non-truncated PUCCH is not allowed, which limits the transmission of SRS, reduces the eNB's ability to measure the uplink channel, and limits the eNB's Scheduling capability, which in turn affects the performance of the entire LTE system

Embodiment 1

[0103] Assume that the UE is configured with 4 uplink CCs, namely CC1, CC2, CC3, and CC4; the UE is configured with 2 PAs, respectively, PA1 and PA2.

[0104] Assume that the current UE does not need to meet condition 1, that is, the high layer allows the UE to transmit through signaling instructions or through semi-static configuration parameters; but only needs to meet condition 2, that is, the UE judges to allow transmission according to the configuration of the uplink CC.

[0105] In this case, the eNB notifies the UE through DCI (Downlink Control Information) to divide CC1 and CC2 that use the same PA for transmission into CC group 1, and divide CC3 and CC4 that use another PA for transmission For CC group 2.

[0106] or;

[0107] The UE decides by itself through a predefined grouping method, divides CC1 and CC2 that use the same PA1 for transmission into CC group 1, and divides CC3 and CC4 that use another PA2 for transmission into CC group 2.

Embodiment 1-1

[0109] It is assumed that there is a PUSCH to be sent in CC1, an SRS is sent by CC2, an SRS is sent by CC3, and there is no relevant content to be sent by CC4 in the current subframe.

[0110] Then, in CC group 1, the transmission method in the current R10 version LTE standard 36.213 is adopted, the SRS is discarded, and only the PUSCH is transmitted.

[0111] Since the PUSCH on CC1 and the SRS on CC3 do not belong to the same CC group, they can be sent at the same time.

[0112] Then the UE sends the PUSCH on CC1 and the SRS on CC3 at the same time.

Embodiment 1-2

[0114] It is assumed that CC1 has a non-truncated PUCCH to be sent, CC2 sends SRS, CC3 sends SRS, and CC4 has no relevant content to send in the current subframe.

[0115] In CC group 1, the transmission method in the current R10 version LTE standard 36.213 is adopted, the SRS is discarded, and only the non-truncated format PUCCH is transmitted.

[0116] Since the PUSCH on CC1 and the SRS on CC3 do not belong to the same CC group, they can be sent at the same time.

[0117] Then the UE sends the non-truncated PUCCH on CC1 and the SRS on CC3 at the same time.

Abstract

The invention discloses a method and system for realizing signal transmission, which can simultaneously transmit physical uplink shared channels and / or physical uplink control channels and measurement reference signals for different power amplifiers in user equipment using multiple power amplifiers . The present invention realizes signal transmission technology, realizes simultaneous transmission of measurement reference signals between component carriers, and physical uplink shared channel and / or physical uplink control channel, expands the transmission mode of measurement reference signals, and can effectively improve the measurement of uplink channels ability, thus improving the scheduling ability, thereby improving the performance of the entire long-term evolution system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and system for realizing signal transmission. Background technique [0002] LTE-Advanced (Long Term Evolution Advanced, 3GPP Long Term Evolution) is an evolved version of LTE (Long Term Evolution, 3GPP Long Term Evolution), and its purpose is to meet the higher demands and more applications of the wireless communication market in the next few years, to meet and It exceeds the requirements of IMT-Advanced (International MobileTelecommunications-Advanced, Advanced International Mobile Communications), while maintaining good backward compatibility with LTE. [0003] In order to meet this requirement, a CA (Carriers Aggregation, carrier aggregation) technology is adopted in LTE-Advanced to further support a communication bandwidth wider than that of LTE. Carrier aggregation can be divided into two application scenarios: discontinuous carrier aggregation (Inter-band CA) and...
