Problems solved by technology

However, high-frequency communication also faces a big technical challenge. Compared with low-frequency signals, high-frequency communication signals have a very large attenuation in space, which leads to a decrease in the quality of outdoor communication. However, due to the reduction in wavelength, it can be used More antennas to communicate based on beams to compensate for fading loss in space
In this way, in order to...

Embodiment Construction

[0254] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. 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.

[0255] figure 1 It is a flowchart of an implementation of the uplink access method of the present invention, such as figure 1 shown, including:

[0256] Step 100: The terminal requests uplink access from one or more first base stations according to the obtained access configuration information.

[0257] Before this step also include:

[0258] The terminal obtains the uplink access configuration information according to the system broadcast message from the second base station. Specifically, the terminal receives the downlink synchronization signal and system message sent p...

Abstract

The invention discloses an uplink access method, a terminal and a base station. The uplink access method includes the steps: according to the obtained access configuration information, requesting uplink access to one or more first base stations, by means of a terminal; receiving the related information of uplink access, returned from the one or more first base stations, wherein the related information of uplink access contains the related information of downlink synchronization, for performing downlink synchronization; and according to the obtained related information of uplink access, selecting a first base station for performing uplink access. The technical scheme of the uplink access method enables the terminal to complete uplink access and complete downlink synchronization with the selected one or more first base stations at the same time, and can obtain part of the system information of the accessed first base station. Therefore, one or more first base stations do not need sending synchronization signals and the part of system information periodically, so that the system consumption caused by sending of the synchronization signals and the system information can be greatly reduced and the system resource can be saved.

Description

technical field [0001] The invention relates to mobile communication technology, in particular to an uplink access method, a terminal and a base station. Background technique [0002] Research shows that in the existing Long Term Evolution (LTE, Long Term Evolution) system design, the resource utilization rate is relatively low, for example, the average resource utilization rate is between 2% and 20%. For system signals such as synchronization signals, system broadcast messages, and common reference signals, no matter whether there are users staying in the cell or users need to send and receive data, the system signals are sent periodically or every subframe. The difference in power consumption of base stations with light loads (such as 2% resource usage) and heavy loads (such as 20% resource usage) is not very different, that is to say, the transmission of system signals occupies most of the power consumption of the base station Therefore, in the evolution of LTE, it is ne...
