Problems solved by technology

At this time, because no feedback is received for sending preambles on all beams, UE hopes to send through beam 1 again, but with a higher power
However, according to the existing protocol, when the UE switches from beam 3 to beam 1, the UE can only maintain the same power, so that the UE cannot increase the power, and the base station cannot receive the preamble

Embodiment Construction

[0057] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.

[0058] figure 1 is a flow chart of a random access method shown in an exemplary embodiment of the present application. This embodiment is described from the UE side, as shown in figure 1 As shown, the random access method includes:

[0059] In step S101, it is judged whether the currently selected beam for sending the preamble is the same as at least one recorded beam for sending the preamble....

Abstract

The present disclosure relates to a random access method and device, user equipment, and a computer-readable storage medium. Wherein, the random access method includes: judging whether the currently selected beam for sending the preamble sequence is the same as at least one recorded beam for sending the preamble; if the currently selected beam is the same as one of the recorded beams, clearing the previous record For all the beams, record the currently selected beam, and when it is determined that the value of the pilot power boost counter has not reached the maximum value, use the boosted pilot transmit power to send the preamble. The embodiment of the present disclosure realizes that the transmit power can be increased when the UE performs beam handover, thereby increasing the probability that the base station receives the preamble.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a random access method and device, user equipment, and a computer-readable storage medium. Background technique [0002] In a Long Term Evolution (LTE for short) system, a base station sends a broadcast to cover an entire sector through a beam (beam). In New Radio (NR), the base station can cover a sector by scanning with a narrower beam, that is, the base station only sends a narrow beam in a certain direction at a certain moment, and then continuously changes the beam direction to achieve coverage of one sector. Such a scenario is called a multi-beam (Multi-beam) scenario. [0003] In the Multi-beam scenario, the user equipment (UE) first correlates to a best downlink beam by measuring the downlink signal. For a UE capable of sending and receiving consistency (Tx-Rx correspondence), the UE can determine the most suitable uplink beam by receiving the do...
