Problems solved by technology

However, since the load size of PUCCH transmission and the time-frequency resources occupied by PUCCH transmission all affect the power of PUCCH, the existing power control of PUCCH cannot accurately reflect the effects of these factors

Embodiment 1

[0304] The base station configures the power control parameters of the PUCCH for the UE, and the power control parameters are PUCCH resource configuration Δ F_PUCCH (F), or Δ F_PUCCH (F) Reference amount and Δ F_PUCCH (F) correction amount. Among them, Δ F_PUCCH (F) represents the transmission power offset.

[0305] The transmit power offset can be configured in two parts: a reference amount of the transmit power offset and a correction amount of the transmit power offset.

[0306] The sum of the correction amount of the transmit power offset and the transmit power reference amount can obtain the transmit power offset.

[0307] Alternatively, the correction amount of the transmission power offset may be a transmission power offset.

[0308] Since the PUCCH resource is configured with the format of the PUCCH, the starting position of the RB, the number of RBs, the starting position of the OFDM symbol, the number of OFDM symbols, and whether to hop frequency, the base stati...

Embodiment 2

[0318] The base station configures the power control parameters of the PUCCH for the UE, specifically including: configuring N Δ for the PUCCH resource set F_PUCCH (F) or Δ F_PUCCH (F) The reference amount and Δ F_PUCCH (F) The correction amount, the N Δ F_PUCCH (F) or Δ F_PUCCH The correction amounts of (F) respectively correspond to different load intervals, wherein, N is an integer greater than or equal to 1. The UE selects one of the N Δ according to the actual load size of the PUCCH transmission F_PUCCH (F), or Δ F_PUCCH The correction amount of (F) performs power control of the PUCCH.

[0319] Since the maximum payload size is configured on the PUCCH resource set, the Δ based on the set configuration F_PUCCH (F) can reflect the difference in load.

[0320] For example, when N is 2, it corresponds to a large load interval and a small load interval. The boundary of the payload interval may be predefined, for example, the interval greater than 11 bits is called a la...

Embodiment 3

[0338] The base station configures the power control parameters of the PUCCH for the UE, specifically including: configuring N Δ for the BWP F_PUCCH (F), the N Δ F_PUCCH (F) respectively correspond to different load intervals, wherein, N is an integer greater than or equal to 1. The UE selects one of the N Δ according to the actual load size of the PUCCH transmission F_PUCCH (F) Perform power control of the PUCCH.

[0339] For example, when N is 2, it corresponds to a large load interval and a small load interval. For example, more than 11 bits are called a large payload interval, and less than or equal to 11 bits are called a small payload interval.

[0340] For example, the base station configures one CC for the UE, including three BWPs, and the first BWP is configured with a PUCCH. 2 Δ are configured on the BWP F_PUCCH (F), corresponding to the large load interval and the small load interval, respectively.

[0341] In addition to load factors, factors such as the numb...

Abstract

The invention discloses a power control method and device, a base station, a terminal and a computer readable storage medium. The method comprises the following steps that a second communication nodeconfigures a power control parameter for a first communication node; wherein the power control parameter comprises an offset of at least one sending power; wherein the offset of the sending power is determined by at least one of the following values: the size of a load transmitted by the PUCCH, the number of orthogonal frequency division multiplexing (OFDM) symbols occupied by the PUCCH, the number of resource blocks RB occupied by the PUCCH, and whether the PUCCH hops or not. According to the invention, the offset of the sending power determined by at least one of the size of the load transmitted by the PUCCH, the number of OFDM symbols occupied by the PUCCH, the number of resource blocks RB occupied by the PUCCH and whether the frequency of the PUCCH is hopped or not is configured for the first communication node; therefore, the two communication parties can control the uplink transmitting power of the PUCCH more accurately.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular to a power control method and device, a base station, a terminal, and a computer-readable storage medium. Background technique [0002] 5G New Radio (New Radio, NR) is an ongoing third generation partnership (3rd Generation Partnership Project, 3GPP) research project, which determines the new wireless air interface based on Orthogonal Frequency Division Multiplexing (OFDM) standard and will be the basis for the next generation of mobile networks. As the fifth-generation mobile communication system, NR technology needs to support an unprecedented number of different types of application scenarios, and also needs to support traditional frequency bands, high frequency bands, and beam modes at the same time, which brings great challenges to the design of power control. [0003] The power of uplink transmission is related to many factors, such as path loss, ta...
