example 1
[0139] Example 1, the single-beam terminal and single-site communication mode, on the basis of steps S1510 to S1542, further includes the following steps:
[0140] Step S1551, in the subsequent m+i (i≥1) downlink time slot, the terminal adopts the same method as B m,k The receive beam corresponding to the signal, receive and measure the transmit beam of the available site 2;
[0141] Step S1561, the terminal determines the RSRP value Rnm of the transmit beam of the available site 2, and executes step S1571;
[0142] In step S1571, when the value of Rnm is less than the first threshold value T12, the network side determines that the communication mode is the single-site communication mode, and repeats step S1551.
example 2
[0143] Example 2, the dual-beam terminal and single-site communication mode, on the basis of steps S1510 to S1542, further includes the following steps:
[0144] Step S1552, the terminal receives and measures the transmit beam of available site 2 in the subsequent m+i (i≥1) downlink time slot;
[0145] Step S1562, the terminal determines the RSRP value Rnm of the transmit beam of the available site 2, and executes step S1574;
[0146] Step S1574, when the value of Rnm is less than the first threshold T12, the network side determines that the communication mode is the single-site communication mode, informs the terminal of the communication mode, and repeats step S1552.

[0147] Example 3, single-beam terminal and dual-site mode, on the basis of steps S1510 to S1542, the following steps are further included:
[0148] Step S1551, in the subsequent m+i (i≥1) downlink time slot, the terminal adopts the same method as B m,k The receive beam corresponding to the signal, receive and measure the transmit beam of the available site 2;
[0149] Step S1561, the terminal determines the RSRP value Rnm of the transmit beam of the available site 2, and executes step S1572;
[0150] Step S1572, when the value of Rnm corresponding to the nth (1≤n≤N) transmit beam is greater than or equal to the first threshold T12, denote the beam sequence number corresponding to Rnm as B m+i,n , the terminal is used with B m+i,n The receiving beam corresponding to the signal establishes a connection with the available site 2, and at the same time, the network side determines the available site 2 as the target site 2, and selects the multi-site cooperative communication mode w...

Abstract
Provided are a communication mode selection method, a base station, a terminal and a storage medium, the communication mode selection method comprising: acquiring beam identification information from the terminal, the beam identification information being identification information of a target transmission beam of an available site, the target transmitting beam is determined and obtained by the terminal from transmitting beams of the available stations according to a first threshold value; determining an available site corresponding to the beam identification information as a target site; and determining a communication mode according to the number of the target sites, so that the terminal communicates with the target sites according to the determined communication mode. According to the scheme provided by the embodiment of the invention, the network side can determine the target stations according to the beam identification information and determine the communication mode according to the number of the target stations, so that the selection of the communication mode is realized.
Description
technical field [0001] The present invention relates to, but is not limited to, the field of communications, and in particular, to a method for selecting a communication mode, a base station, a terminal, and a storage medium. Background technique [0002] High-frequency communication has the characteristics of ultra-large capacity and ultra-high speed, and has broad application prospects. However, the loss of high-frequency communication is relatively large, resulting in a small coverage of the site, and it is necessary to increase the number of sites to ensure the coverage of the high-frequency network. In this case, it is easy for the terminal to be located in the coverage of multiple sites at the same time. In order to make full use of site resources, a multi-site cooperative communication mode is proposed in the relevant standards, which can simultaneously serve as the terminal through two or more sites. Provide communication services. [0003] However, in the current ...
