Description
Technical Field
The invention relates to the technical field of communication, in particular to a method for improving energy-saving efficiency of UE, the UE and an NR system.
Background
BWP (BandWidth Part, which is a continuous BandWidth in a cell configuration frequency band and may be less than or equal to a cell BandWidth) configuration parameters are defined in the 3GPP wireless NR system 38.331 protocol, and are used to flexibly configure the BWP supporting various bandwidths for the UE. When the UE is configured to work in the BWP with small bandwidth, the power of the UE can be saved, and the energy saving of the UE is facilitated. The relevant protocol definition is shown in fig. 1.
As shown in fig. 1, the base station may configure BWP-inactivity timer and default downlink BWP-Id parameters for the UE, and when the UE does not receive or transmit data within the time indicated by BWP-inactivity timer, the base station may automatically switch to the bandwidth-less BWP indicated by the default downlink BWP-Id, so as to achieve the purpose of saving power and energy.
38.331 protocol now defines only a downlink default BWP, and when there is no data transceiving for a downlink service at a specific time, BWP can be automatically switched, but when there is no data transceiving for a long time, BWP cannot be automatically switched, which results in that the uplink BWP cannot automatically switch the default BWP to achieve the purpose of saving energy, and reduces the efficiency of energy saving for the UE.
Disclosure of Invention
The present invention provides a method for improving energy saving efficiency of a UE, a UE and an NR system, so as to solve the problem that energy saving efficiency of the UE cannot be improved due to the fact that an uplink BWP cannot be automatically switched to a default BWP according to a service in a 3GPP wireless NR system.
The invention provides a method for improving energy-saving efficiency of UE, which comprises the following steps:
by optimally designing Uu interface signaling, the uplink BWP is automatically switched to default uplink BWP when no uplink service exists at the specified time, and therefore energy-saving efficiency of UE is improved.
Further, the optimization design of the Uu interface signaling means that a parameter is newly added in a 3gpp 38.331 protocol to configure the uplink BWP and automatically switch to the default uplink BWP when no uplink service exists at a specified time.
Further, the newly added parameters in the 3gpp 38.331 protocol include:
adding a parameter uplink-BwpInactivatyTimer in a 3GPP 38.331 protocol, wherein the parameter uplink-BwpInactivatyTimer is used for configuring the duration of an uplink BWP (broadband remote protocol) inactivity timer;
and newly adding a parameter defaultUpdinkBWP-Id in a 3GPP 38.331 protocol, wherein the parameter defaultUpdinkBWP-Id is used for configuring a default uplink BWP ID.
Further, when the UE monitors that no uplink service exists within the duration of the parameter uplink-BwpInactivationTimer, the UE is automatically switched to the default uplink BWP configured by the parameter defaultUpplinkBWP-Id.
The invention also provides the UE which saves energy by adopting the method for improving the energy-saving efficiency of the UE.
The invention also provides a 3GPP wireless NR system, and the 3GPP wireless NR system comprises the UE.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:
by optimally designing Uu interface signaling and adding new parameters in the 3GPP 38.331 protocol, the invention can effectively increase the times of switching the UE to the default uplink BWP, achieve the purpose of saving more power for the UE and contribute to improving the energy-saving efficiency of the UE.

adding a parameter uplink-BwpInactivatyTimer in a 3GPP 38.331 protocol, wherein the parameter uplink-BwpInactivatyTimer is used for configuring the duration of an uplink BWP (broadband remote Access protocol) inactivity timer;
