Detailed Description
The inventors noted during the course of the invention that:
In the process that UE performs SMALL DATA transmission in the inactive state, if the UE wants to modify the SMALL DATA transmission configuration of the UE after sending UL SMALL DATA, the network side needs to:
send RRC RELEASE a message, or;
the UE is instructed to enter the RRC connected state, and is instructed through an RRC resume or RRC reconfiguration (RRC reconfiguration) message.
It can be seen that when the small data of the UE changes, such as the data size, or the channel condition changes, the network side cannot configure the configuration authorization of the UE in the inactive state, and only can enter the RRC connection state, or send RRC RELEASE a message again to reconfigure the CG. But this introduces the problem of greater delay and signaling overhead.
Based on this, in the embodiment of the present invention, a SMALL DATA configuration scheme is provided, after the base station determines SMALL DATA resource information used by the UE, the base station sends an activated part or all of the SMALL DATA resources to the UE after receiving the data or the data request of the UE SMALL DATA; or information to reconfigure some or all of the SMALL DATA resources. Further, the UE is configured with N sets of configuration grants and/or SPS resource information in RRC RELEASE messages, where N >1. When the UE has small data transmission in the inactive state, the UE selects or informs the available configuration authorization information of the network side, and the network side indicates/activates the configuration authorization resource to transmit the small data. The following describes specific embodiments of the present invention with reference to the drawings.
In the description process, description will be made from the implementation of the UE and the base station side, respectively, in which the base station side will describe the transmission process, the UE side will describe the detection process, and then an example of the implementation of the two in cooperation will also be given to better understand the implementation of the scheme given in the embodiment of the present invention. Such a description does not mean that the two must be implemented cooperatively or separately, and in fact, when the UE and the base station are implemented separately, they solve the problems of the UE side and the base station side, respectively, and when the two are used in combination, a better technical effect is obtained.
