Description

Power control method based on multi-beam, user terminal and base station

Technical Field

The embodiment of the invention relates to the technical field of communication, in particular to a power control method based on multiple beams, a user terminal and a base station.

Background

In a future 5G (5Generation, fifth Generation) mobile communication system, high frequency communication and large-scale antenna technology will be introduced to achieve the target of 20Gbps for downlink transmission rate and 10Gbps for uplink transmission rate. High-frequency communication can provide wider system bandwidth, and the size of the antenna can be smaller, which is more beneficial to the deployment of large-scale antennas in base stations and User Equipment (UE). The Multi-beam/Multi-TRP (Multi-beam/Multi-transmitting node) transmission and reception at the base station side can be widely applied. Taking NR (New Radio ) PUSCH (Physical Uplink shared Channel) as an example, the Uplink Multi-beam transmission is schematically shown in fig. 1.

In the system, the UE triggers a PHR (Power Headroom Report) Report according to a trigger condition specified by a protocol. The content reported in the PHR includes: maximum power that can be sent on each cell; the power margin after the UE sends an uplink control channel (such as PUCCH) on each cell; power headroom after the UE transmits an uplink data channel (e.g., PUSCH (physical uplink control channel)) on each cell; and the power headroom after the UE transmits an uplink sounding channel (e.g., SRS (channel sounding reference signal)) in each cell. If the UE sends a real physical channel, reporting the power margin of the physical channel after the physical channel is really sent. And if the UE does not send the real physical channel, reporting the power margin after sending the reference (or virtual) physical channel of the real physical channel.

However, the existing power control method is not suitable for the multi-beam transmission scenario.

If a certain beam (or beam pair, or beam group, or beam set) is configured with a PUCCH, and the UE has a real PUCCH to transmit, the UE reports the power headroom after the real PUCCH is transmitted.

If a certain beam (or beam pair, or beam group, or beam set) is configured with a PUCCH, and the UE does not have real PUCCH transmission or network configuration to calculate power headroom according to reference channel transmission, the UE reports the power headroom after transmitting the reference (or virtual) PUCCH.

If a certain beam (or beam pair, or beam group, or beam set) is configured with an SRS, and the UE has a real SRS transmission, the UE reports the power headroom after the real SRS transmission.

If a certain beam (or beam pair, or beam group, or beam set) is configured with an SRS, and the UE does not have real SRS transmission or network side configuration to calculate power headroom according to reference channel transmission, the UE reports the power headroom after transmitting the reference (or virtual) SRS.
