Method and communication device for broadcast beam processing

Abstract

The present application discloses a broadcast beam processing method, including: sending a first broadcast beam; receiving a first measurement report from a first terminal; determining a weak coverage area of ​​the first broadcast beam according to the first measurement report; sending a second A broadcast beam, the second broadcast beam is used to cover the weak coverage area of ​​the first broadcast beam. The present application implements and also provides a corresponding communication device. In this embodiment of the present application, according to the first measurement report received from the first terminal under the coverage of the first broadcast beam, the weak coverage area of ​​the first broadcast beam may be determined. Sending the second broadcast beam to cover the weak coverage area of ​​the first broadcast beam can improve the broadcast channel quality of the weak coverage area of ​​the first broadcast beam and increase the user access ratio.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a broadcast beam processing method and a communication device. Background technique [0002] With the rapid development of wireless communication technologies, the emergence of various communication services leads to an increasing demand for spectrum resources. In an environment where the capacity of spectrum resources is gradually saturated, improving spectrum utilization becomes the main development direction. Massive multiple-input multiple-output (MM) antenna technology is a technology that can effectively improve spectrum utilization. [0003] With the advent of the 5th generation mobile communication technology (5G) era, broadcast channels are covered in a scanning manner by narrow beams formed by beam forming (BF). The MM antenna in 5G technology has more digital channels, which can form more beams and cover a larger area. However, the numbe...

Problems solved by technology

However, the number of broadcast beams is limited. For example, the new wireless (new radio, NR) protocol limits the number of broadcast beams for 5G communication to a maximum of 8. Due to the narrow beams and the small number of beams, the broadcast channel coverage cannot be compared with the data channel coverage. Keep the scope consistent

If all broadcast beams are scanned in the vertical plane, it will result in poor broadcast channel coverage in the horizontal plane; if all broadcast beams are scanned in the horizontal plane, it will result in poor broadcast channel coverage in the vertical plane

When the coverage of the broadcast channel is smaller than the coverage of the data channel, the received signal strength of the terminal in the weak coverage area not covered by the broadcast channel is weak, which leads to misjudgment of the actual data transmission capability of the terminal, resulting in the inability of the terminal to access
