The uplink data transmission method of the embodiment of the present invention may be applied to a 5G unlicensed frequency band system, and in the 5G unlicensed frequency band system, SRS resources may be configured on any symbol in a time slot, please refer to fig. 3, where fig. 3 is a schematic diagram of a configuration manner of the SRS resources of the 5G unlicensed frequency band system, and in the embodiment shown in fig. 3, SRS resources are configured on the 1 st symbol, the 9 th to 12 th symbols, and the 14 th symbol in a time slot, and may be used to transmit an SRS. Of course, the SRS is not limited to the configuration shown in fig. 3. The SRS in the embodiments of the present invention may be a periodic SRS, a semi-persistent SRS, and an aperiodic SRS.

In addition, in the 5G unlicensed system, the network side may configure the SRS to start transmission at an arbitrary position of one slot, and may also configure the minimum transmission length L.

In a 5G unlicensed band system, a network side may schedule or pre-configure a terminal to transmit a PUSCH on a slot or a mini-slot (slot), please refer to fig. 4 and fig. 5, where fig. 4 is a schematic configuration diagram of the PUSCH of the 5G unlicensed band system, and fig. 5 is a schematic configuration diagram of the PUSCH of the 5G unlicensed band system. In the unlicensed band, if a slot or a micro-slot is used for transmitting the PUSCH, there may be multiple PUSCH transmission start times in the slot or the micro-slot, where the first position of the slot is the transmission start time of the first PUSCH. In general, PUSCH requires transmission to start at its transmission start time.

It should be noted that, in the unlicensed frequency band, the terminal needs to go through an LBT process before transmitting the SRS or the physical uplink channel, and may transmit the SRS or the physical uplink channel only after the LBT is successful.

In the embodiment of the present invention, the transmission priority of the physical uplink channel and the SRS in the transmission timeslot may be determined according to the following priority rule.

1. Priority rule 1

In some embodiments of the present invention, the determining the transmission priority of the physical uplink channel and the SRS in the transmission timeslot by using the LBT success time and the initial transmission time of the physical uplink channel in the transmission timeslot as the priority determination time point includes: and if the LBT success time is positioned in the sending time slot and is positioned after the sending starting time of the physical uplink channel, and before the target starting sending time of the physical uplink channel from the LBT success time, preferentially sending the SRS, wherein the target starting sending time of the physical uplink channel is the nth starting sending time of the physical uplink channel after the LBT success time, and n is a positive integer which is more than or equal to 1.

Optionally, the preferentially transmitting the SRS includes: and if the SRS is transmitted from the LBT successful moment to the target initial transmission moment of the physical uplink channel, transmitting the SRS. Further optionally, the preferentially transmitting the SRS includes: and if no SRS is transmitted from the LBT successful moment to the target initial transmission moment of the physical uplink channel, transmitting the physical uplink channel.

Optionally, the target initial sending time of the physical uplink channel is a first initial sending time of the physical uplink channel after the LBT success time, that is, if the LBT success time is located in the sending timeslot and after the sending initial time of the physical uplink channel, the SRS is preferentially sent from the LBT success time to before a next initial sending time of the physical uplink channel.

Further optionally, after the preferentially transmitting the SRS, the method further includes: and after the target initial sending time of the physical uplink channel, preferentially sending the physical uplink channel.

Optionally, the preferentially sending the physical uplink channel includes: and if the physical uplink channel is transmitted, transmitting the physical uplink channel, and if the physical uplink channel is not transmitted, transmitting the SRS.

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 (which may be after the first transmission start time of the physical uplink channel or after other transmission start times of the physical uplink channel), before the LBT success time and before the target start transmission time of the physical uplink channel, the SRS is preferentially transmitted, 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 physical uplink channel is transmitted after the LBT succeeds, and after the target transmission start time of the physical uplink channel, the physical uplink channel is preferentially transmitted, that is, the transmission priority of the physical uplink channel is higher than the transmission priority of the SRS, so as to improve the efficiency of the uplink system.

The following examples illustrate:

referring to fig. 6, in the embodiment shown in fig. 6, 14 symbols configured by the network side in one slot for the terminal may all transmit SRS, the network side configures 2 mini-slots with a length of 7 symbols for the terminal in the same slot for transmitting PUSCH, and the starting symbol of the 1 st mini-slot is the 1 st symbol and the starting symbol of the 2 nd mini-slot is the 8 th symbol. Assuming that the terminal succeeds in LBT at the 3 rd symbol time, according to the priority rule 1, the SRS is transmitted at the 4 th to 7 th symbols, that is, the transmission priority of the PUSCH is lower than that of the SRS in the first mini-slot. In the second mini-slot, the transmission priority of the PUSCH is higher than that 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 no PUSCH is transmitted in the second mini-slot, then the 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 in one slot for transmitting a PUSCH, and certainly, in some other embodiments of the present invention, mini-slots with other lengths may also be configured for a terminal for transmitting a PUSCH, which is not limited in the present invention.

2. Priority rule 2

In some embodiments of the present invention, the determining the transmission priority of the physical uplink channel and the SRS in the transmission timeslot by using the LBT success time and the initial transmission time of the physical uplink channel in the transmission timeslot as the priority determination time point includes: if the LBT success time is located before the sending time slot, preferentially sending the SRS from the starting time of the sending time slot to a target initial sending time of a physical uplink channel, or preferentially sending the physical uplink channel, wherein the target initial sending time of the physical uplink channel is an nth initial sending time of the physical uplink channel after the starting time of the sending time slot, and n is a positive integer greater than or equal to 1.

Optionally, the preferentially transmitting the SRS includes: and if the SRS is transmitted from the starting time of the transmission time slot to the target initial transmission time of the physical uplink channel, transmitting the SRS. Further optionally, the preferentially transmitting SRS further includes: and if no SRS is transmitted from the starting time of the transmission time slot to the target initial 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 from the starting time of the transmission time slot to the target starting transmission time of the physical uplink channel, transmitting the physical uplink channel. Further optionally, the preferentially sending the physical uplink channel further includes: and if no physical uplink channel is transmitted from the starting time of the transmission time slot to the target initial transmission time of the physical uplink channel, transmitting the SRS.

Optionally, the target initial sending time of the physical uplink channel is a first initial sending time of the physical uplink channel after the starting time of the sending timeslot, that is, if the LBT success time is located before the sending timeslot, the SRS is preferentially sent from the starting time of the sending timeslot to before a next initial sending time of the physical uplink channel, or the physical uplink channel is preferentially sent.

Further optionally, the preferentially transmitting the SRS, or preferentially transmitting the physical uplink channel further includes: and after the target initial sending time of the physical uplink channel, preferentially sending the physical uplink channel.

Optionally, the preferentially sending the physical uplink channel includes: and if the physical uplink channel is transmitted 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: and if no physical uplink channel is transmitted after the target initial transmission time of the physical uplink channel, transmitting the SRS.

In the embodiment of the present invention, if the LBT success time is located before the transmission timeslot, the physical uplink channel may be preferentially transmitted before the starting time of the transmission timeslot (i.e. the first starting transmission time of the physical uplink channel) to the target starting transmission time of the physical uplink channel, and the advantage of the physical uplink channel transmission over the SRS transmission is that the uplink system efficiency can be improved. Alternatively, the SRS may be preferentially transmitted, and the advantage of preferential SRS transmission over physical uplink channel transmission is that the terminal has more opportunities to transmit the SRS, and the network side can acquire uplink channel information from 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 send SRS, and configures 2 mini-slots with a length of 7 symbols for the terminal in the same slot for transmitting PUSCH, where the starting symbol of the 1 st mini-slot is the 1 st symbol and the starting symbol of the 2 nd mini-slot is the 8 th symbol. If the sending time slot of the SRS is the same as the sending time slot of the PUSCH, the LBT of the terminal succeeds before the sending time slot, and the priority rule 2 is supposed to specify that the SRS is sent preferentially, the terminal sends the SRS in the 1 st to 7 th symbols, and the 1 st mini-slot does not send the PUSCH. Assuming that priority rule 2 specifies that PUSCH is transmitted preferentially, the terminal transmits PUSCH at 1 st mini-slot, and no SRS is transmitted at 1 st to 7 th symbols. The priorities of the PUSCH of the 2 nd mini-slot and the SRS of the 8 th to 14 th symbols may be specified to preferentially transmit the PUSCH. And when the terminal does not transmit PUSCH in the 1 st or 2 nd mini-slot, the terminal transmits SRS on the SRS symbol configured in the slot.

Optionally, the preferentially sending the SRS with the minimum transmission length of L symbols in the transmission slot includes: and if the SRS is transmitted before the target initial transmission time of the physical uplink channel after the LBT successful time, transmitting the SRS. Further optionally, the preferentially transmitting the SRS includes: and if no SRS is transmitted before the target initial transmission time of the physical uplink channel after the LBT success time, transmitting the physical uplink channel.
