The disclosure relates to a field of wireless communication technology, in particular to a method for processing beam failure of a deactivated SN and an apparatus for a processing beam failure of a deactivated SN.
In high-frequency communication, in order to cope with infrequent big data streams, a secondary cell group (SCG) will enter a deactivated state when there is no larger data packet to be transmitted. A user equipment (UE) and a network side save a context of the SCG, and suspend some activities simultaneously, to reduce a power consumption of the UE.
However, the related art lacks a means of beam failure recovery (BFR) when the SCG is in the deactivated state and beam failure has occurred.
According to a first aspect of the disclosure, a method for processing beam failure of a deactivated SN, performed by a UE, is provided. The method includes:
According to a second aspect of the disclosure, a method for processing beam failure of a deactivated SN, performed by a reporting node, is provided. The method includes:
According to a third aspect of the disclosure, a method for processing beam failure of a deactivated SN, performed by a deactivated network side device, is provided. The method includes:
It should be understood that the content described in this section is not intended to identify key or important features of the embodiments of the disclosure, nor is it intended to limit the scope of the disclosure. Additional features of the disclosure will be easily understood from the following description.
The accompanying drawings are used to better understand this solution and do not constitute a limitation to the disclosure, in which:
The following description of exemplary embodiments of the disclosure is provided in combination with the accompanying drawings, which includes various details of the embodiments of the disclosure to aid in understanding, and should be considered merely exemplary. Those skilled in the art understood that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the disclosure. For the sake of clarity and brevity, descriptions of well-known functions and structures are omitted from the following description.
A method for processing beam failure of a deactivated SN, an apparatus for processing beam failure of a deactivated SN, a terminal, a network side device and a storage medium of the embodiments of the disclosure are described below with reference to the accompanying drawings.
In order to reduce power consumption of the UE for infrequent big data streams, a deactivated secondary cell group (SCG) is introduced in the 5G new radio (NR) release 17 (R17) standard. The deactivated SCG is equivalent to that the SCG is in the dormant state, or the SCG is suspended, or the primary SCG cell (PSCell) is suspended, or the PSCell is in the dormant state, or the PSCell is deactivated. When there is no large data packet to be transmitted, the SCG enters into the deactivated state, and the UE and the network side save the context of the SCG and suspend some behaviors, for example, stopping listening to a physical downlink control channel (PDCCH) on the SCG side, to reduce the power consumption of the UE. When there is a large data stream to be interacted, the SCG of the UE is quickly activated for data transmission.
In order to quickly activate the SCG for data transmission, it is possible that the UE still performs beam failure detection (BFD) on the SCG side when the SCG is in the deactivated state, and the behavior of the UE is not yet defined when the UE detects that beam failure occurs on the SCG side.
Accordingly, the method for processing beam failure of a deactivated SN provided by the embodiment of the disclosure includes: in response to an SCG and/or a PSCell entering a deactivated state, reporting a message indicating beam failure of the specific SCG to a reporting node upon detecting that beam failure occurs to the deactivated SCG, in which the reporting node is a master node (MN) or another activated SN, the SCG is the deactivated SCG and/or an SCG to which the deactivated PSCell belongs, and the corresponding node of the SCG is a deactivated SN; receiving a response message fed back by the reporting node, and performing processes based on the response message. Therefore, beam failure recovery (BFR) when the SCG is in the deactivated state is realized.
For ease of understanding, the terms involved in this disclosure are introduced.
To improve a data transmission rate, the network can configure the SCG for the UE to share load, so as to improve the data transmission rate of the UE. After the network configures the SCG for the UE, the UE accesses the SN in a special cell (SpCell) of the SCG, i.e., PSCell. The network can configure bearer transport for the UE in the SCG. The UE maintains configuration information of both the MCG and the SCG simultaneously.
The NR R17 project is expected to support the deactivated SCG. The deactivated SCG is equivalent to that the SCG is suspended, or the SCG is in the dormant state, or the primary SCG cell (PSCell) is deactivated, or the PSCell is suspended, or the PSCell is in the dormant state, which is aimed for infrequent big data streams. When there is no large data packet to be transmitted, the SCG enters into the deactivated state, and the UE and the network side save the context of the SCG and suspend some behaviors, for example, stopping listening to the PDCCH on the SCG side, not listening to the SCG channel, stopping data transmission on the SCG side, and stopping random access etc., to achieve the purpose of saving the power consumption of the UE. When there is a large data stream to be interacted, the SCG of the UE is quickly activated for data transmission. The UE may continue to maintain behaviors such as the BFD when the SCG is in the deactivated state.
The existing protocol supports the UE to connect to two nodes simultaneously, i.e., an MN and an SN, but a multi-connection architecture is also expected to be supported in the future, that is, the UE connects to two or more nodes simultaneously, e.g., an MN and multiple SNs, and the nodes are identified by different identification information, e.g., Cell group ID.
The 5G NR system supports multi-beam, and the UE needs to select a suitable beam to access the network side through measurement. The UE in a connected state will perform beam failure detection (BFD) on a serving cell. When the UE detects that beam failure occurs to the SpCell, the UE may trigger a random access procedure to realize the BFR. In the case where the UE detects that beam failure occurs to the SCell, it triggers the BFR by reporting to the media access control control element (MAC CE) via a corresponding MAC entity. That is, the MAC CE carries indication information of the SCell to which beam failure occurs and may also carry indication information of a suitable measurement signal, so that the network side may learn about a suitable beam based on the indication information and recover the beam that connects the SCell to the UE.
