In the embodiment of the invention, the transmission priority of the physical uplink channel and the SRS in the transmission time slot can be determined according to the following priority rule.
1. Priority rule 1
In some embodiments of the present invention, the determining, with the LBT success time and the initial transmission time of the physical uplink channel in the transmission slot as priority determination time points, the transmission priority of the physical uplink channel and the SRS in the transmission slot includes: and if the LBT success time is positioned in the transmission time slot and is positioned after the transmission starting time of the physical uplink channel, preferentially transmitting SRS from the LBT success time to the target starting transmission time of the physical uplink channel, wherein the target starting transmission time of the physical uplink channel is the nth starting transmission time of the physical uplink channel after the LBT success time, and n is a positive integer greater than or equal to 1.

Further optionally, the preferentially transmitting SRS includes: and if no SRS is transmitted before the LBT success time to the target initial transmission time of the physical uplink channel, transmitting the physical uplink channel.
Optionally, the target initial transmission time of the physical uplink channel is the first initial transmission time of the physical uplink channel after the LBT success time, that is, if the LBT success time is located in the transmission time slot and is located after the transmission initial time of the physical uplink channel, the SRS is preferentially transmitted from the LBT success time to before the next initial transmission time of the physical uplink channel.
Further optionally, the preferentially sending SRS further includes: and after the target initial transmission time of the physical uplink channel, preferentially transmitting the physical uplink channel.
Optionally, the preferentially sending the physical uplink channel includes: if there is a physical uplink channel transmission, a physical uplink channel is transmitted, and if there is no physical uplink channel transmission, an SRS is transmitted.
In the embodiment of the present invention, if the LBT success time is located in the transmission timeslot and is located after the transmission start time of the physical uplink channel (may be after the first transmission start time of the physical uplink channel or after other transmission start times of the physical uplink channel), the SRS is preferentially transmitted before the LBT success time to the target start transmission time of the physical uplink channel, that is, the transmission priority of the SRS is higher than the transmission priority of the physical uplink channel, so that the transmission gap is filled before the transmission of the physical uplink channel after the LBT success, and the physical uplink channel is preferentially transmitted after the target transmission start time of the physical uplink channel, that is, the transmission priority of the physical uplink channel is higher than the transmission priority of the SRS, thereby improving the uplink system efficiency.
The following examples illustrate:
referring to fig. 6, in the embodiment shown in fig. 6, 14 symbols configured by the network side for the terminal in one slot can all transmit SRS, and the network side configures 2 mini-slots with 7 symbols in length for the terminal in the same slot for transmitting PUSCH, where the 1 st symbol is the 1 st symbol and the 2 nd symbol is the 8 th symbol. Assuming that the terminal succeeds in LBT at the 3 rd symbol time, the SRS is transmitted in the 4 th to 7 th symbols according to the priority rule 1 described above, that is, the transmission priority of PUSCH is lower than that of SRS in the first mini-slot. In the second mini-slot, the transmission priority of the PUSCH is higher than the transmission priority of the SRS, that is, the terminal transmits the PUSCH in the second mini-slot and does not transmit the SRS. If the terminal (when there is no PUSCH transmission in the second mini-slot, SRS is transmitted on the 8 th to 14 th symbols.
In the embodiment of the present invention, 2 mini-slots with a length of 7 symbols are configured for a terminal to transmit PUSCH in one slot, and of course, in other embodiments of the present invention, other lengths of mini-slots may be configured for a terminal to transmit PUSCH.
2. Priority rule 2
In some embodiments of the present invention, the determining, with the LBT success time and the initial transmission time of the physical uplink channel in the transmission slot as priority determination time points, the transmission priority of the physical uplink channel and the SRS in the transmission slot includes: and if the LBT successful time is positioned before the transmission time slot, preferentially transmitting SRS from the starting time of the transmission time slot to the target starting transmission time of the physical uplink channel, or preferentially transmitting the physical uplink channel, wherein the target starting transmission time of the physical uplink channel is the nth starting transmission time of the physical uplink channel after the starting time of the transmission time slot, and n is a positive integer greater than or equal to 1.
Optionally, the preferentially sending SRS includes: and if SRS transmission exists before the starting time of the transmission time slot to the target starting transmission time of the physical uplink channel, transmitting the SRS. Further optionally, the preferentially transmitting SRS further includes: and if no SRS transmission exists before the starting time of the transmission time slot to the target starting transmission time of the physical uplink channel, transmitting the physical uplink channel.
Optionally, the preferentially sending the physical uplink channel includes: and if the physical uplink channel is transmitted before the target initial transmission time of the physical uplink channel from the starting time of the transmission time slot, transmitting the physical uplink channel. Further optionally, the preferentially sending the physical uplink channel further includes: and if no physical uplink channel is transmitted before the target initial transmission time of the physical uplink channel from the starting time of the transmission time slot, transmitting SRS.
Optionally, the target initial transmission time of the physical uplink channel is the first initial transmission time of the physical uplink channel after the start time of the transmission time slot, that is, if the LBT success time is located before the transmission time slot, the SRS is preferentially transmitted from the start time of the transmission time slot to the next initial transmission time of the physical uplink channel, or the physical uplink channel is preferentially transmitted.
Further optionally, the preferentially sending SRS, or after preferentially sending the physical uplink channel, further includes: and after the target initial transmission time of the physical uplink channel, preferentially transmitting the physical uplink channel.
Optionally, the preferentially sending the physical uplink channel includes: if there is a physical uplink channel to transmit after the target initial transmission time of the physical uplink channel, transmitting the physical uplink channel. Further optionally, the preferentially sending the physical uplink channel further includes: if no physical uplink channel is transmitted after the target initial transmission time of the physical uplink channel, SRS is transmitted.
In the embodiment of the present invention, if the LBT success time is located before the transmission time slot, before the start time of the transmission time slot (i.e., the first start transmission time of the physical uplink channel) reaches the target start transmission time of the physical uplink channel, the physical uplink channel may be preferentially transmitted, and the physical uplink channel transmission is preferentially transmitted over the SRS transmission, which has the advantage of improving the uplink system efficiency. Alternatively, the SRS may be preferentially transmitted, where the SRS transmission has a benefit over the physical uplink channel transmission that the terminal has more opportunities to transmit the SRS, and the network side can acquire the uplink channel information according to the SRS.
The following examples illustrate:
referring to fig. 7, in the embodiment shown in fig. 7, the network side configures 14 symbols in one slot for the terminal to transmit SRS, and configures 2 mini-slots with 7 symbols in length for the terminal in the same slot for PUSCH transmission, where the 1 st symbol is the 1 st symbol and the 2 nd symbol is the 8 th symbol. If the SRS transmission slot is the same as the PUSCH transmission slot, the LBT is successful before the transmission slot by the terminal, and assuming that the priority rule 2 specifies that the SRS is preferentially transmitted, the terminal transmits the SRS in the 1 st to 7 th symbols, and the 1 st mini-slot does not transmit the PUSCH. Assuming that the priority rule 2 specifies that PUSCH is preferentially transmitted, the terminal transmits PUSCH at the 1 st mini-slot, and the 1 st to 7 th symbols do not transmit SRS. The priorities of PUSCH of the 2 nd mini-slot and SRS of the 8 th to 14 th symbols may be specified as priority transmission of PUSCH. And when the 1 st or 2 nd mini-slot is transmitted without the PUSCH, the terminal transmits the SRS on the SRS symbol configured in the time slot.
