Beam Selection Method and Communication Apparatus - A simplified explanation of the abstract
This abstract first appeared for US patent application 17793311 titled 'Beam Selection Method and Communication Apparatus
Simplified Explanation
This patent application describes a method and apparatus for selecting a beam in a communication network. The method includes the following steps:
1. A terminal receives a downlink reference signal from a network device on two different beams. 2. The terminal measures the received signal strength (RSRP) and the maximum permissible exposure (MPE) for each beam. 3. The terminal calculates the difference between the RSRP and the back-off power for each beam. 4. If the difference between the RSRP and the back-off power is greater for the first beam than the second beam, the terminal sends uplink data using the first beam.
Key points:
- The method allows a terminal to select the best beam for sending uplink data based on measured signal strength and back-off power.
- The terminal measures the RSRP and MPE separately for each beam to obtain accurate measurements.
- The difference between the RSRP and the back-off power is used as a criterion for selecting the beam.
- This method improves the efficiency and reliability of communication in the network.
Original Abstract Submitted
A beam selection method and a communication apparatus are provided, which relate to the field of communication technologies. The method includes: A terminal receives a downlink reference signal from a third beam of a network device on a first beam and a second beam; then, the terminal performs RSRP measurement and MPE measurement on the first beam and the second beam separately to obtain first RSRP, second RSRP, first back-off power, and second back-off power; and when a difference between the first RSRP and the first back-off power is greater than a difference between the second RSRP and the first back-off power, the terminal sends uplink data by using the first beam. In this technical solution, the terminal may select an uplink working beam with reference to the measured back-off power of the first beam and the measured back-off power of the second beam.
