Embodiment approach

[0114] The service operation information includes the number of users in the cell, the flow information of the cell and / or the utilization rate of physical resources. When based on the number of users in the cell, the flow of the cell or the application of physical resources, in one embodiment, the way to determine B(x) is: :

[0115] When the number of cell users, cell traffic or physical resource utilization is greater than or equal to the first preset value, determine that the value of the buffer size in B(x) is small (such as the first value); the number of cell users, cell traffic or physical resources When the utilization rate is less than or equal to the second preset value, it is determined that the buffer size in B(x) is larger (such as the second value); wherein, the first preset value is greater than the second preset value; the number of users in the cell, When the cell traffic or physical resource utilization is between the first preset value and the second preset...

Abstract

The embodiment of the invention provides a configuration method and device for uplink data compression UDC, a base station and a terminal. The method comprises the following steps: determining a UDC configuration parameter of a terminal according to a first UDC recommendation parameter of the terminal determined by network statistical information and / or a second UDC recommendation parameter reported by the terminal; and sending the UDC configuration parameter to the terminal. According to the method, the UDC configuration parameters of the terminal are determined according to the first UDC recommendation parameter of the terminal determined by the network statistical information and / or the second UDC recommendation parameter reported by the terminal, so that different UDC configuration parameters can be configured for each terminal to obtain the optimal compression gain, and the problems of capacity, processing complexity, system performance, terminal power consumption and the like are effectively considered, so the performance balance in all aspects is ensured.

Description

technical field [0001] The present invention relates to the field of wireless technology, in particular to a configuration method, device, base station and terminal for uplink data compression UDC. Background technique [0002] In the current wireless network technology, in order to alleviate the limitation of uplink capacity and improve edge performance, an uplink enhancement scheme is proposed, that is, an uplink data compression (Uplink Data Compression, UDC) technology. This technology can compress the data transmitted in the uplink, so as to improve the uplink capacity and save uplink physical resources. [0003] Currently, the base station can send UDC configuration parameters to the terminal, so that the terminal can perform UDC processing on the transmitted data according to the UDC configuration parameters and then send it to the base station. However, the base station has no clear standard for determining the UDC configuration parameters of the terminal. If the pa...
