Random access method and related equipment

Abstract

The embodiment of the invention discloses a random access method, which is applied to the field of communication. The method comprises the steps: terminal equipment sending a first message for establishing a wireless connection to network equipment, the terminal equipment receiving a connection response sent by the network equipment, the connection response comprising information of a first polarization parameter; and when the terminal equipment accesses the network equipment according to the connection response, whether the terminal equipment has the qualification of accessing the network equipment or not is confirmed according to the information of the first polarization parameter included in the connection response. By introducing the dimension of the polarization parameter in the random access process, the capacity of the lead code is improved, the problem that the network equipment cannot identify the terminal equipment which collides with the network equipment is relieved, and the efficiency of establishing communication connection between the terminal equipment and the network equipment is improved.

Description

technical field [0001] The embodiment of the present application relates to the communication field, in particular to a random access method and related equipment. Background technique [0002] Compared with the long term evolution (long term evolution, LTE) system, the protocol standard of the fifth generation cellular mobile communication system formulated by the third generation partnership project (3GPP) standard organization, the new air interface (New Radio, NR ) system supports larger transmission bandwidth, more transceiver antenna arrays, higher transmission rate, and more flexible and smaller-granularity scheduling mechanism. The above characteristics of the NR system provide more scope of application. [0003] In an existing communication mechanism, when data interaction is performed between a terminal device and a network device, the terminal device may request to establish a communication connection with the network device by sending a preamble to the network de...

Problems solved by technology

The existing communication mechanism is difficult to meet the communication needs between the terminal device and the network device. Taking the random access process as an example, when two terminal devices send the same preamble to the network device, the terminal device used by the user will collision

In the existing communication mechanism, due to the small capacity of the preamble, the probability of terminal device collision is high, and often the network device cannot identify the collided terminal device due to the collision of terminal devices

Inefficiency in establishing communication connections between end devices and network devices
