230. The terminal sends, in the time domain scheduling unit, at least part of the physical channels of the multiple physical channels by using transmit power corresponding to at least part of the physical channels.

Specifically, sending the at least part of the physical channels of the multiple physical channels may refer to sending the uplink signals by using at least part of the plurality of physical channels.

It should be noted that the transmit power of the remaining physical channels except the at least part of the physical channels may be 0 dB, and the remaining physical channels except the at least part of the physical channels are transmitted. The power may be a preset transmit power, which is not specifically limited in this embodiment of the present application.

Specifically, the physical channel in the information type carried by the physical channel may include a data channel and a control channel, and the priority of the physical channel may be determined according to the type of information carried in the data channel or the physical channel.

For example, for a data channel, the priority of the data channel can be determined based on whether the type of information carried in the time domain scheduling unit of the data channel is data or control signaling. In the first time domain scheduling unit, if the information carried by the data channel is data, the data channel may be configured with a lower priority. In the second time domain scheduling unit, the information carried by the data channel is control signaling. The data channel can be configured with a higher priority. In summary, the data channel can have different priorities in different time domain scheduling units.

The type of the above physical channel may refer to the type determination of the physical channel transmission signal. For example, the type of the physical channel may include an uplink control channel, an uplink shared channel carrying Uplink Control Information (UCI), an uplink shared channel, and a physical channel for transmitting an uplink sounding signal.

For example, the characteristic parameters of the physical channel include the channel type of the physical channel, and the foregoing rule is used to indicate the correspondence between the channel type and the priority of the physical channel, and the second priority rule may indicate that the priority of the uplink control channel is higher than that of the bearer carrying UCI. The priority of the shared channel is higher than the priority of the uplink shared channel is higher than the priority of the physical channel transmitting the uplink sounding signal.

It should be understood that, when determining the priority of the physical channel according to the characteristic parameter of the physical channel, the priority of the physical channel may be determined according to a characteristic parameter of the physical channel, and the priority of the physical channel may be determined by combining the characteristic parameters of the multiple physical channels. The application examples are not specifically limited thereto.

It should also be understood that when determining the priority of the physical channel according to the characteristic parameters of the plurality of physical lanes, the priority of the physical channel may be determined according to the priority of the different types of characteristic parameters of the physical channel. For example, the priority of the start time of the physical channel is higher than the priority of the transmission time unit of the physical channel, that is, the terminal may first determine the priority of the physical channel according to the start time of the physical channel, and then according to the transmission of the physical channel. Time determines the final priority of the physical channel. The priority of the feature parameters of the physical channel is not specifically limited in this embodiment of the present application. For example, the priority of the physical channel type may be higher than the priority of the physical channel start time, the priority of the physical channel start time may be higher than the priority of the physical channel transmission time unit; or the priority of the physical channel type may be lower than The priority of the physical channel start time, the priority of the physical channel start time may be lower than the priority of the physical channel transmission time unit.

For example, FIG. 3 shows a schematic diagram of physical channel characteristic parameters of an embodiment of the present application. From Figure 3 As shown in the three physical channels, the start time of the first physical channel is the same as the start time of the third physical channel, and the start time of the second physical channel is on the first physical channel and the third physical channel. After the start time. The length of the transmission time unit of the first physical channel is the same as the length of the transmission time unit of the second physical channel, and the time corresponding to the transmission time unit of the third physical channel is longer than the length of time corresponding to the transmission time unit of the first physical channel and the second physical channel. .

Determining the priority of the physical channel according to the transmission time unit of the physical channel and the duration of the physical channel, assuming that the starting time of the physical channel has a higher priority than the transmission time unit of the physical channel, and determining the starting of the physical channel The priority of the start time may determine the transmission of the physical channel according to the order of the physical channel starting from the high priority of the start time to the low priority of the start time, corresponding to the order of the start time of the physical channel from the front to the back. The priority of the time unit may be in accordance with the order of the time length of the transmission time unit in the physical channel from the high priority of the transmission time unit to the low priority of the transmission time unit, in order of short to long, according to the physics The start time of the channel may determine that the start times of the first physical channel and the third physical channel have the same priority, and the start time of the second physical channel has a lower priority than the start of the first physical channel and the third physical channel. The priority of time. The time length corresponding to the transmission time unit of the first physical channel is shorter than the time length corresponding to the transmission time unit of the third physical channel, and then the priority of the transmission time unit of the first physical channel may be determined to be higher than the transmission time of the third physical channel. The priority of the unit. In summary, the priority of the first physical channel is higher than the priority of the third physical channel, and the priority of the third physical channel is higher than the priority of the second physical channel.

For another example, the terminal may determine the priority of the physical channel by combining the first priority rule and the second priority rule, where the second priority rule is a correspondence between a channel type of the physical channel and a priority of the physical channel. The first physical channel is an uplink shared channel, and the second physical channel is also an uplink shared channel, and the first physical channel has the same priority as the second physical channel, but the first physical channel uses the CP-OFDM multiple access method. The second physical channel uses the DFT-S-OFDM multiple access mode, and the priority of the first physical channel is lower than the priority of the second physical channel.

For example, the terminal may determine that the priority of the uplink control channel is higher than the priority of the uplink shared channel according to the priority of the physical channel and the priority of the physical channel, and the priority of the physical channel using the DFT-S-OFDM multiple access mode is high. The priority of the physical channel using the CP-OFDM multiple access method. In summary, the terminal can determine the priority of the uplink control channel using the DFT-S-OFDM multiple access method, which is higher than the priority of the uplink control channel using the CP-OFDM multiple access method, and is higher than using the DFT-S-OFDM multiple access. The priority of the uplink shared channel is higher than that of using CP-OFDM. The priority of the uplink shared channel in the address mode.

Optionally, as an embodiment, the method further includes: the terminal receiving the indication information sent by the network device, where the indication information is used to indicate the second priority rule.

Specifically, the second priority rule that the terminal determines the priority of the physical channel may be indicated by the network device to the terminal. For example, the network device can adjust the second priority rule in real time according to the current communication quality, so as to improve the flexible washability of the terminal determining the priority of the physical channel.

Optionally, as an embodiment, the feature parameter of the physical channel includes a transmission time unit that passes through a physical channel, and the priority indicated by the second priority rule corresponds to a physical order from a high priority to a low priority. The length of time of the transmission time unit in the channel is from short to long.

Specifically, the transmission time unit of the physical channel may be a mini-slot or a slot, and the transmission time unit of the physical channel may further include multiple slots. For example, when the transmission time unit of the physical channel includes multiple time slots, the second priority rule may indicate that the priority level of the transmission time unit in the physical channel is shorter than the priority order of the high priority to the low priority. In the long order, that is, sequentially, the number of time slots included in the transmission time unit in the physical channel is in descending order. Optionally, as an embodiment, the feature parameter of the physical channel includes a start time of the physical channel, and the priority indicated by the second priority rule sequentially corresponds to the physical channel by a high priority to a low priority. The start time is from front to back.

The service type includes an ultra-reliable and low-latency communication URLLC service and an enhanced mobile bandwidth eMBB service, and the priority of the physical channel carrying the service as the URLLC service is higher than the priority of the physical channel carrying the eMBB service.

Optionally, as an embodiment, the method further includes: the terminal reducing at least one of the multiple physical channels according to a priority of the multiple physical channels and/or a priority of the multiple physical channels The transmit power of part of the physical channel.

Specifically, the reducing the transmit power of at least part of the physical channels of the multiple physical channels may include transmitting a transmit power of at least a part of the plurality of physical channels to 0 dB, that is, there may be multiple physical channels. Part of the channel does not transmit signals to control the sum of the transmit powers of other physical channels whose transmit power is not 0 dB in multiple physical channels is less than or equal to the maximum of the terminal.
