Example Embodiment
[0046] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.
[0047] figure 1 It is a schematic diagram of a carrier aggregation application scenario 100 according to an embodiment of the present invention. The application scenario 100 includes a base station 104, a UE 102, and CCs 106, 108, and 110.
[0048] The present invention divides the scenarios of simultaneous transmission of multiple data channels with limited power under carrier aggregation into two types: PUSCH w / o UCI and multiple PUSCHs (hereinafter all refer to PUSCH without UCI).
[0049] Such as figure 2 As shown, based on the above two scenarios, the method includes the following steps:
[0050] S1. The UE receives the CC open-loop power control parameters sent by the base station;
[0051] S2, the UE obtains ...
