example 1

[0054] Example 1. The system determines the access success rate of the scheduling-free access terminal according to the number of scheduling-free access terminals and the number of successful access terminals. If the access success rate is less than the preset value r, the system increases the Scheduling the number of uplink resource groups or reducing the size of the scheduling-free uplink resource groups. If the capacity of the scheduling-free uplink resource pool is not limited, the capacity of the scheduling-free uplink resource pool can be increased first, so that the size of the scheduling-free uplink resource group can be maintained and the number of scheduling-free uplink resource groups in the pool can be increased. If the capacity of the scheduling-free uplink resource pool is limited, reduce the size of the scheduling-free uplink resource group and increase the number of scheduling-free uplink resource groups in the pool.

example 2

[0055] Example 2, the system determines the proportion of terminals that repeatedly apply for uplink resources (such as terminals that do not request system allocation of resources) according to the terminal's uplink resource allocation requirement information (the proportion is the number of terminals whose eSR feedback is "00" to the feedback eSR The ratio of the number of all terminals), if the ratio is smaller than the preset value k, increase the size of the scheduling-free uplink resource group. If the capacity of the scheduling-free uplink resource pool is not limited, ensure that the number of scheduling-free uplink resource groups in the pool remains unchanged, and increase the size of each scheduling-free uplink resource group. If the capacity of the scheduling-free uplink resource pool is limited, reduce the number of scheduling-free uplink resource groups in the pool and increase the size of each scheduling-free uplink resource group under the condition of giving pr...

Abstract

The invention discloses uplink transmission and uplink transmission control methods and devices, and a communication system, and relates to the field of mobile communication. The uplink transmission method comprises the following steps: a terminal utilizes a scheduling-free access leader sequence broadcast by a system to acquire a scheduling-free uplink resource group corresponding to the scheduling-free access leader sequence from the system; an enhanced uplink scheduling request is transmitted to the system through the scheduling-free uplink resource group, wherein the request comprises scheduling request information and uplink resource quantity allocation demand information, so that the system, in response to the enhanced uplink scheduling request, allocates uplink resources for the terminal according to the uplink resource quantity allocation demand information; and the terminal performs uploading and transmitting by utilizing the uplink resources allocated by the system. The uplink resources are acquired in a scheduling-free mode, so that rapid transmission is achieved; and meanwhile, the system is requested once to allocate the uplink resources by the enhanced uplink scheduling request, so that compared with multi-time scheduling requests, the uplink transmission time delay can be shortened, and the occupied wireless resources can be reduced.

Description

technical field [0001] The present disclosure relates to the field of mobile communications, and in particular to an uplink transmission and its control method and device, and a communication system. Background technique [0002] In current mobile communication systems, for example, LTE-A (Long Term Evolution-Advanced) system, the resource scheduling mechanism of SR (Scheduling Request, scheduling request) + BSR (Buffer Status Report, buffer status report) is used for uplink transmission. The user equipment (UE, User Equipment) tells the system whether it needs uplink resources for transmission through SR, but the SR will not tell the system how much uplink data needs to be transmitted, and then the system allocates enough uplink resources for BSR transmission to the UE, and the UE subsequently sends a BSR notification How many uplink resources the system needs to allocate for transmission. [0003] However, this uplink transmission mode results in a long UE uplink resource...
