Embodiment Construction

[0063] Embodiments of the present application provide a power control method, related devices and products, which are used to enable a receiving end to receive signals normally.

[0064] The system architecture or scenarios mainly used in this application are as follows: figure 1 As shown, including access network equipment and terminal equipment. Both access network equipment and terminal equipment can work in the base station and terminal equipment on the licensed frequency band or license-free frequency band. Whether it is a licensed frequency band or an unlicensed frequency band, in this application, it can include one or more carriers. The licensed frequency band and the unlicensed frequency band perform carrier aggregation, which can include one or more carriers included in the licensed frequency band and the unlicensed frequency band. Carrier aggregation for one or more carriers.

[0065] The access network device may be an evolutionary Node B in a long term evolution...

Abstract

The embodiment of the invention discloses a power control method, a related device and a product, which are used for enabling a receiving end to normally receive signals. The method provided by the embodiment of the invention comprises the following steps: the UE determines the initial transmission power of the first type of PUSCH, the UE determines that the actual sending power of the first typeof PUSCH in the time period when the second type of PUSCH is not transmitted in the transmission time unit of the first type of PUSCH is the first power, wherein the length of the transmission time unit of the first type of PUSCH is greater than the length of the transmission time unit of the second type of PUSCH, the first power is greater than or equal to the initial transmission power and lessthan or equal to the maximum power of the UE for transmitting the PUSCH; the UE determines that the actual sending power of the first type of PUSCH in the time period for transmitting the second typeof PUSCH in the transmission time unit of the first type of PUSCH is second power, and the sum of the second power and the transmitting power of the second type of PUSCH is less than or equal to the maximum power of the UE for transmitting the PUSCH.

Description

technical field [0001] The present application relates to the communication field, and in particular to a power control method, related devices and products. Background technique [0002] Future 5G wireless communications mainly include three major application scenarios, enhanced mobile broadband (eMBB), ultra-reliable and low latency communications (URLLC) and massive machine type communications (mMTC) ), the non-orthogonal multiple access (NOMA) technology in the 5G wireless communication system allows multiple user data to be transmitted on the same time-frequency resource. [0003] For the same user equipment (user equipment, UE), when the UE transmits a physical uplink shared channel (physical uplink shared channel, PUSCH), there may be both the first type of PUSCH and the first type of PUSCH on the same time-frequency resource. The two types of PUSCH will independently calculate their transmission power according to the power control formula in the standard and their ...
