Problems solved by technology

[0004] The existing technology only provides a solution, but it has not been practically applied. In the actual implementation, the difference between the FDD system and the TDD system needs to be considered, and the specific configuration method of each parameter needs to be considered

Embodiment Construction

[0037] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] The basic idea of ​​the present invention is: firstly determine the sending cycle period of the user scheduling request and the uplink subframe for transmitting the scheduling request according to the service status of the user in the cell, and then use the total number of scheduling request resources in the cell and the number of uplink subframes for transmitting the scheduling request Determine the scheduling request resource that can be allocated for each uplink subframe, then allocate the determined scheduling request resource and the specific uplink subframe where the resource is located to the user, and notify the user of the scheduling request resource and the uplink subframe where the resource is located and the sending cycle of scheduling requests.

Abstract

The invention discloses a method for allocating uplink dispatch request, comprising the following steps: determining the transmission circle period of each user dispatch request and uplink subframes for transmitting dispatch request in the transmission circle period by a base station according to service condition of users in a subdistrict; determining the dispatch request resource capable of being assigned of each uplink subframe used for transmitting dispatch request by using the total of the available dispatch request resources in the subdistrict and the number of the uplink subframes for transmitting request in the transmission circle period; assigning the dispatch request resource to users; sending the transmission circle period, the assigned dispatch request resource and the uplink subframes in which the dispatch request resource is located to the corresponding users. By adopting the invention, uplink dispatch request allocation can be realized in an LTE system.

Description

technical field [0001] The invention relates to a data transmission technology in a long-term evolution (LTE) system, in particular to a method for configuring an uplink scheduling request. Background technique [0002] In the LTE system, after user equipment (UE) accesses the system, if it wants to initiate data transmission, it needs to send a scheduling request (SR) to the base station first. After receiving the scheduling request, the base station will allocate appropriate resources to the UE. For UE to perform uplink data transmission. [0003] The scheduling request is the information sent by the UE to apply for uplink transmission resources. In order to instruct the UE to send the scheduling request on a suitable and available resource, the base station needs to configure the uplink scheduling request for the UE in advance, so as to allocate currently available scheduling request resources for the UE. It is used to transmit the scheduling request and notify the UE of...
