Problems solved by technology

For the situation where the number of user equipment (User Equipment, referred to as UE for short) is relatively small, there is a problem of resource waste in periodically broadcasting and sending LTE system messages
In order to alleviate the waste of resources and high power consumption of the base station caused by broadcasting LTE system messages, operators began to consider sending system messages by category to solve the above problems

Abstract

The invention relates to methods and apparatuses for sending and receiving system messages, user equipment, and a base station. The method for receiving system messages includes the following steps: if first-type system messages broadcast by the base station are received, determining a reception window and a preorder guide code of system messages to be requested, the system messages to be requested belonging to second-type system messages; if the reception window of the system messages to be requested reaches, sending the preorder guide code in an uplink sub-frame used for sending the preorder guide code; and receiving, in the reception window of the system messages to be requested, the system messages to be requested that are sent by the base station according to the reception window. Through the technical scheme of the invention, combination and sending together of multiple SIs leads to too much preorder guide code requirements and further leads to a problem that the base station cannot send the SIs at the same time if the UE applies the multiple SIs once. Moreover, the system message sending and receiving performance is greatly improved.

Description

technical field [0001] The present disclosure relates to the technical field of communications, and in particular to a method, device, user equipment and base station for sending and receiving system messages. Background technique [0002] With the rapid development of wireless communication technology, the number of Long Term Evolution (referred to as LTE) system information (referred to as SI) increases, and the transmission of LTE system information by periodic broadcasting makes the power consumption of the base station Larger, lower spectrum resource utilization. For a situation where the number of user equipments (User Equipment, referred to as UE for short) is relatively small, there is a problem of resource waste in periodically broadcasting and sending LTE system messages. In order to alleviate the waste of resources and high power consumption of base stations caused by broadcasting LTE system messages, operators began to consider sending system messages by categor...
