Specifically, the physical channel in the information type of above-mentioned physical channel carrying may include data channel and control channel, then the priority of the physical channel can be determined according to the information type carried in data channel or physical channel.
For example, the type for the information that can be carried in time domain scheduling unit according to the data channel is the priority that data or control signaling determine the data channel for data channel.In the first time domain scheduling unit, the information of data channel carrying is data, it then can be the data channel configuration preference level be low, in the second time domain scheduling unit, the information of data channel carrying is control signaling, then can be the data channel configuration preference level be it is high, in conclusion the data channel can have different priority in different time domain scheduling units.

Such as, the characteristic parameter of physical channel includes the channel type of physical channel, above-mentioned rule is used to indicate the channel type of physical channel and the corresponding relationship of priority, and the second priority rule can refer to that the priority of uplink control channel is higher than the priority of the physical channel of transmission uplink detection signal higher than the priority that the priority of the Uplink Shared Channel of carrying UCI is higher than Uplink Shared Channel.
It should be understood that, when determining the priority of physical channel according to the characteristic parameter of physical channel, the priority of physical channel can be determined according to a characteristic parameter of physical channel, the characteristic parameter that can be combined with multiple physical channels determines that the priority of physical channel, the embodiment of the present application are not especially limited this.
It should also be understood that can determine the priority of physical channel according to the priority of the different types of characteristic parameter of physical channel when determining the priority of physical channel according to the characteristic parameter on multiple physics trades.Such as, the priority of the initial time of physical channel is higher than the priority of the transmission time unit of physical channel, that is, terminal can first determine the priority of physical channel according to the initial time of physical channel, the final priority of physical channel is determined further according to the transmission time of physical channel.The embodiment of the present application is not specifically limited the priority of the characteristic parameter of physical channel.For example, the priority of physical channel type can be higher than the priority of physical channel initial time, the priority of physical channel initial time can be higher than the priority of physical channel transmission time unit；Or the priority of physical channel type can be lower than the priority of physical channel initial time, the priority of physical channel initial time can be lower than the priority of physical channel transmission time unit.
For example, Fig. 3 shows the schematic diagram of the physical channel characteristics parameter of the embodiment of the present application.From Fig. 3
Shown in 3 physical channels as can be seen that the initial time of the first physical channel is identical with the initial time of third physical channel, the initial time on the second physics trade is after the initial time of the first physical channel and third physical channel.The transmission time unit length of first physical channel is identical with the transmission time unit length of the second physical channel, and the transmission time unit corresponding time of third physical channel is longer than the corresponding time span of transmission time unit of the first physical channel and the second physical channel.
According to the transmission time unit of physical channel and the duration of physical channel, when determining the priority of physical channel, assuming that the priority of the initial time of physical channel is higher than the priority of the transmission time unit of physical channel, and determine that the priority of the initial time of physical channel can be corresponding in turn to the rule of the sequence of the initial time of physical channel from front to back by the putting in order for low priority of high priority to the initial time of initial time according to physical channel, determine that the priority of the transmission time unit of physical channel can be according to the rule of the sequence of the time span of the transmission time unit being corresponding in turn in physical channel that puts in order of the low priority of the high priority by transmission time unit to transmission time unit from short to long, of the first physical channel and third physical channel can be then determined according to the initial time of physical channel The priority of time beginning is identical, and the priority of the initial time of the second physical channel is lower than the priority of the initial time of the first physical channel and third physical channel.The corresponding time span of transmission time unit of first physical channel is shorter than the corresponding time span of transmission time unit of third physical channel, then can determine that the priority of the transmission time unit of the first physical channel is higher than the priority of the transmission time unit of third physical channel.In conclusion the priority of the first physical channel is higher than the priority of third physical channel, the priority of third physical channel is higher than the priority of the second physical channel.
In another example terminal can determine the priority of physical channel in conjunction with the first priority rule and the second priority rule, wherein the second priority rule is the corresponding relationship of the channel type of physical channel and the priority of physical channel.First physical channel is Uplink Shared Channel, second physical channel is also Uplink Shared Channel, then the priority of the first physical channel is identical with the priority of the second physical channel, but the first physical channel uses CP-OFDM multi-access mode, second physical channel uses DFT-S-OFDM multi-access mode, then the priority of the first physical channel is lower than the priority of the second physical channel.
Also for example, terminal can be according to the priority of physical channel and the priority of physical channel, it determines that the priority of uplink control channel is higher than the priority of Uplink Shared Channel, the priority of the physical channel using CP-OFDM multi-access mode is higher than using the priority of the physical channel of DFT-S-OFDM multi-access mode.To sum up, terminal can determine the priority of the uplink control channel using DFT-S-OFDM multi-access mode, it is higher than more using CP-OFDM higher than the priority for the uplink control channel for using CP-OFDM multi-access mode higher than the priority for the Uplink Shared Channel for using DFT-S-OFDM multi-access mode
The priority of the Uplink Shared Channel of location mode.
