Resource allocation method, system and related device

Abstract

The invention discloses a resource allocation method, which comprises the following steps: when user equipment meets a transmission time interval TTI bundling condition, receiving a radio resource control signaling message transmitted by a base station, wherein the message carries TTI bundling information and first uplink static resource allocation information; performing TTI bundling setting according to the TTI bundling information, wherein the TTI bundling information comprises a TTI bundling setting indication; and reallocating uplink static resources according to the first uplink static resource allocation information. The invention also provides a corresponding device and a corresponding system. In the method, the device and the system, the resource allocation information and the TTIbundling information carried in radio resource control RRC signaling are transmitted together to the user equipment to perform the TTI bundling setting and the corresponding static resource reallocation, so the probability of conflict caused by PDCCH loss can be reduced, and resources can be timely and reliably allocated to improve the performance of the system.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a resource configuration method, system and related devices. Background technique [0002] In the Long Term Evolution (LTE, Long Term Evolution) system, in order to overcome the influence of wireless mobile channel time-varying and multipath fading on signal transmission, a Hybrid Automatic Repeat Request (HARQ, Hybrid Automatic Repeat Request) mechanism is used to reduce the bit error rate of the system to ensure service quality. In LTE, the HARQ of the stop-and-wait mode is adopted, that is, the sending end must wait for the confirmation information of the receiving end after sending a piece of data. When the receiving end confirms that the data has been received correctly, the next data transmission will be carried out; otherwise, the data sent last time will be retransmitted. While waiting for the confirmation information, the channel is idle and no da...

Problems solved by technology

[0007] This solution is to reconfigure static resources through PDCCH signaling. PDCCH signaling may be lost during transmission. If the PDCCH that configures resources is lost, UE needs to use the original resources to transmit within the entire binding interval. Will conflict with other UEs

In addition, when TTI bundling is deconfigured, a new PDCCH signaling is required to reconfigure resources, which increases the probability of loss, resulting in untimely and unreliable resource configuration.
