Problems solved by technology

The terminal only selects the access AP among the APs in the working state. In this case, the selected AP cannot be guaranteed to have the best service quality, which will not only affect the communication efficiency of the terminal, but also easily cause waste of power or spectrum resources.

Embodiment Construction

[0024] The application will be described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, but not to limit the present application. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other. In addition, it should be noted that, for the convenience of description, only some structures related to the present application are shown in the drawings but not all structures.

[0025] In the embodiment of the present application, a random access method is provided. The terminal receives the timing pilot signal, so as to select the access AP among the APs that can respond to the PRACH, and expands the selectable access points, so that the terminal can obtain more High quality of service.

Abstract

The invention provides a random access method, an access control method, a terminal, an access point and a storage medium. The random access method comprises the following steps: sending a physical random access channel (PRACH); receiving a timing pilot signal used for responding to the PRACH, detecting a random access response (RAR) message and a physical downlink control channel (PDCCH) used for indicating the RAR message, and determining the timing of the RAR message and the timing of the PDCCH based on the timing of a timing pilot signal; and sending a third message according to the timing pilot signal, the RAR message and the PDCCH, wherein the third message is used for requesting to access a network.

Description

technical field [0001] The present application relates to a wireless communication network, for example, to a method for random access and access control, a terminal, an access point and a storage medium. Background technique [0002] With the deployment and application of various low-power access points such as microcells, small cells, femtocells, and relay nodes, cellular networks are becoming increasingly heterogeneous and dense. For the purpose of saving energy or reducing interference, a part (Access Point, AP) is turned off when the service is sparse, and the terminal can select one of the APs providing coverage to access the network service. However, the AP that provides coverage is independent from the AP that provides capacity, and the AP that provides coverage may not necessarily provide the best service for the terminal. The terminal only selects the access AP among the APs in the working state. In this case, the selected AP cannot be guaranteed to have the best ...
