Embodiment 1
[0159] An embodiment of the present invention provides a method for transmitting an uplink channel, and the execution subject is a UE, such as image 3 As shown, the method includes the following steps:
[0160] 101. The UE determines to use n first channels numbered i to send information and use m second channels numbered j to send information, where the number i The length of the first time unit is the first transmission time interval TTI, the length of the second time unit numbered j is the second TTI, the second TTI is shorter than the first TTI, and at least one of the numbers is The first time unit of i overlaps with at least one second time unit numbered j, and the information sent by the first channel and the second channel correspond to different cells.
[0161] It should be noted that the first channel on n first time units numbered i can be understood as that there is one first channel on each first time unit numbered i, which is equivalent to the existence of n O...
Embodiment 2
[0211] An embodiment of the present invention provides a method for transmitting an uplink channel, and the execution subject is a base station, such as Figure 4 As shown, the method includes the following steps:
[0212] 201. The base station sends the reserved power information of the first transmission time interval TTI and the reserved power information of the second TTI to the UE, so that the UE can compare the time between the first time unit numbered i and the second time unit numbered j When there is overlap, allocate transmit power for the L uplink channels according to the reserved power information of the first TTI and the reserved power information of the second TTI; or send the reserved power information of the second TTI to the UE, so that the When the first time unit numbered i and the second time unit numbered j overlap in time, the UE allocates transmit power for the L uplink channels according to the reserved power information of the second TTI , wherein th...
Embodiment 3
[0223] An embodiment of the present invention provides a method for transmitting an uplink channel, such as Figure 5 As shown, the method includes the following steps:
[0224] 301. The base station sends capability indication information to the UE.
[0225] Wherein, the capability indication information is used to instruct the UE to simultaneously transmit the channel corresponding to the long TTI and the channel corresponding to the short TTI.
[0226] In order to achieve shorter RTT and shorter data transmission delay, a scenario where the TTI length is set to 0.5 ms or shorter has been proposed. Then UE may use 0.5ms TTI to transmit short-latency services (such as small packets / voice) on a cell (cell), and at the same time use 1ms TTI to transmit large data volume services (such as video, download) on this cell. Therefore, the UE can simultaneously support a long TTI (eg: 1ms TTI) and a short TTI (eg: 0.5ms TTI), and the UE can simultaneously transmit the channel corres...
