Problems solved by technology

[0011] Embodiments of the present invention provide a resource scheduling method, a base station, and a communication system to solve the problem that when the loopback time RTT of the synchronous HARQ process and the semi-static scheduling period have the same common multiple, the retransmission of the data packet and the initial transmission of the SPS will occur at the same time The problem of making transmissions and thus causing collisions

Embodiment Construction

[0033] In order to make the purpose, technical solutions, and advantages of the embodiments of the present invention more clearly expressed, the technical solutions provided by the embodiments of the present invention are described in detail below with reference to specific embodiments and accompanying drawings.

[0034] Aiming at the semi-static scheduling SPS of real-time services under the condition of uplink synchronous HARQ in the LTE system, the embodiment of the present invention provides a method for resource scheduling. In this embodiment, when there is real-time service that needs to be transmitted, if it is determined that the real-time service reservation process, the base station determines that the reservation process is used for uplink SPS scheduling; sends a notification message to the user equipment UE, the notification message carries the relevant information of the reserved process; instructs the user equipment UE to use the reserved process The uplink subfra...

Abstract

The embodiment of the invention provides a resource scheduling method, a base station and a communication system. The resource scheduling method comprises the followings: when real-time services needto be transported, determining to reserve a process to be used for upgoing semi-static scheduling if judging the process is needed to be reserved for the real-time services; sending a notification message to user equipment (UE) and instructing the UE to transport a data packet with the upgoing subframe corresponding to the reserved process as a unit. The resource scheduling method provided by theembodiment of the invention reduces the sending frequency of signaling, lowers the signaling cost and transports the services by reserving a plurality of processes to be used for upgoing semi-static scheduling, thus can better solve the conflict problem in upgoing semi-static scheduling in the prior art, greatly improving the properties of the system and elevating the service experience of the users.

Description

technical field [0001] The present invention relates to communication technologies, and in particular, to a resource scheduling method, a base station and a communication system. Background technique [0002] Compared with the current third-generation mobile communication system, the 3GPP Long Term Evolution (LTE) system is based on Packet Switch (PS) in the overall architecture, and is also used as Wideband Code Division Multiple Access (WCDMA). Common long-term evolution with Time Division-Synchronous Code Division Multiple Access TD-SCDMA (Time Division-Synchronous Code Division Multiple Access), retains two kinds of frequency division multiplexing FDD (Frequency Division Duplex) and time division multiplexing TDD (Time Division Duplex) Duplex mode, in which TDD uplink and downlink occupy different uplink and downlink subframes on the same frequency band. In order to more flexibly match the difference in the amount of uplink and downlink traffic, in TDD mode, the uplink ...
