Problems solved by technology

However, in practical applications, in order to ensure that the terminal can successfully complete the contention random access process, it is necessary to reserve a certain length of random access slots, and different lengths of random access slots need to be reserved under different coverage areas. Under coverage, relatively large random access slots must be reserved, and these random access slots cannot be used for data transmission of normal services, thus greatly reducing the utilization efficiency of wireless resources

Abstract

The present invention provides a device access method in a wireless communication system, a terminal device, and an access point device. The method includes: receiving time slot resource allocation information sent by the wireless access point, and the time slot resource allocation information includes random access The start time of the time slot resource in the current wireless frame and the location information of the wireless access point; obtain the estimated value Ta of the uplink timing advance of the terminal device according to the location information of the wireless access point and the terminal device Calc , Ta Calc It is the advance amount of the time for the terminal device to send the uplink random access signal relative to the start time of the random access time slot resource in the current radio frame; according to Ta Calc The random access parameter is determined according to the start time of the random access time slot resource in the current radio frame, and an uplink random access signal is sent according to the random access parameter. The present invention can still ensure the success rate of equipment access after reducing the length of the random access time slot resource, avoid resource waste caused by reserving a larger random access time slot, and improve the utilization rate of wireless resources.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a device access method in a wireless communication system, a terminal device, and an access point device. Background technique [0002] The rapid development of wireless communication technology has brought the development of mobile Internet to an unprecedented height. The pursuit of high-efficiency wireless resource utilization technology to meet the ever-increasing demand for speed and capacity has become the development direction of wireless communication technology. Therefore, improving the utilization rate of wireless resources has become an urgent technical problem to be solved. [0003] The current mainstream wireless communication systems, including LTE, WIFI, etc., all adopt advanced technologies such as OFDM technology, 64QAM or 256QAM high-order modulation technology, which maximizes the efficiency of wireless resource usage. However, in the cu...
