Example Embodiment

[0063] figure 1 A schematic diagram of a millimeter wave communication beam pair link provided by an embodiment of the present invention. refer to figure 1 , the network device 101 generates multiple beams in multiple directions or channels, and the terminal device 102 also generates multiple beams in multiple directions or channels. In order to maintain satisfactory communication performance, during downlink communication (the network device 101 sends a message to the terminal device 102), the transmitting beam of the network device 101 and the receiving beam of the terminal device 102 need to be aligned to form a downlink beam pair link (beam pairlink, BPL ). Correspondingly, during uplink communication (the terminal device 102 sends a message to the network device 101), the transmitting beam of the terminal device 102 and the receiving beam of the network device 101 need to be aligned to form an uplink beam pair link (BPL). When both the terminal device 102 and the netwo...

Abstract

The embodiment of the invention relates to a beam management method and terminal equipment. The method comprises: a terminal device determines first information, the first information being used for indicating a beam tracking capability of the terminal device, and the magnitude of the beam tracking capability of the terminal device being related to the length of time required by the terminal device to reconstruct a beam-to-link after the beam-to-link fails; the terminal equipment determines path loss between the terminal equipment and network equipment serving the terminal equipment; the terminal equipment receives a first message from the network equipment, wherein the first message is used for indicating the terminal equipment to adjust the sending power; and the terminal equipment determines the sending power and the sending beam width of the terminal equipment at least according to the first information, the path loss and the first message. According to the embodiments of the present invention, the problem of width selection of a sending beam of a terminal device can be solved, so as to consider both beam gain and robustness of the beam to a link.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 201810771613.3 and the application name "A Beam Management Method and Terminal" submitted to the China Patent Office on July 13, 2018, the entire contents of which are incorporated by reference in this application . technical field [0002] The present invention relates to the communication field, in particular to a beam management method and terminal equipment. Background technique [0003] The widespread commercial use of the third generation (3G) and fourth generation (4G) mobile communication systems has greatly improved people's communication and enriched people's lives, and promoted the popularization of the mobile Internet. In order to meet the ever-increasing needs of users for wireless and mobile data communications, international communication standards organizations, such as the third generation partnership project (3GPP), have formulated fifth generation (fif...
