Problems solved by technology

[0004] However, usually non-dedicated resources are shared by multiple UEs, and multiple UEs can use this resource. Once multiple UEs use this resource to upload data at the same time, the base station will not be able to correctly decode the uploaded data. At this time, the uplink transmission of the UE will be If it fails, the UE needs to apply to the base station for scheduling resources again for data transmission, which increases the signaling overhead and causes data transmission delays

Embodiment Construction

[0048] As mentioned in the background technology, non-dedicated resources are usually shared by multiple UEs, and multiple UEs can use this resource. Once multiple UEs use this resource to upload data at the same time, the base station will not be able to correctly decode the uploaded data. At this time The uplink transmission of the UE cannot be successful, and the UE needs to apply to the base station for scheduling resources again for data transmission, which increases signaling overhead and causes data transmission delay.

[0049] At the same time, since the non-dedicated resources are sent by the base station to the UE through signaling, the transmission of the signaling requires a certain time delay. Moreover, some UEs configured with non-dedicated resources are not in the uplink synchronization state. When multiple UEs need to use non-dedicated resources at the same time, the base station cannot quickly configure non-dedicated resources, resulting in serious conflicts of...

Abstract

The invention provides a method and apparatus for adjusting non-dedicated resources, a base station and user equipment. The method comprises the following steps: detecting the non-dedicated resourcescurrently used by the user equipment; when it is detected that the power of at least a part of the non-dedicated resources is less than a first threshold or when the data loaded by the non-dedicated resources cannot be decoded, adjusting the non-dedicated resources; sending indication information to at least a part of user equipment, wherein the indication information is used for indicating an adjustment manner of the non-dedicated resources, so that the at least a part of user equipment determines the adjusted non-dedicated resources according to the adjustment manner, and uses the adjusted non-dedicated resources to perform uplink data transmission. By adoption of the technical scheme provided by the invention, the adjustment of the non-dedicated resources can be achieved, and the data transmission efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a non-dedicated resource adjustment method, device, base station and user equipment. Background technique [0002] In mobile communication systems such as the Long Term Evolution (LTE) system and the fifth-generation mobile communication technology (5-Generation, 5G) system, after the user equipment (User Equipment, UE) completes uplink synchronization in the access network, according to The uplink grant (Up-Link Grant, UL Grant) sent by the base station sends data to the base station at the designated time-frequency resource location, and the base station determines whether to send an acknowledgment (ACKnowledge, ACK) or a non-acknowledgment (Negative ACKnowledge, NACK) to the base station according to the reception situation. UE. If the UE receives a non-acknowledgment signal, the UE may need to retransmit the data. [0003] In the prior art, usually before...
