Description

Method for recovering beam failure, terminal equipment and network equipment
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for recovering a beam failure, a terminal device, and a network device.
Background
In a future 5G (5Generation, fifth Generation) mobile communication system, high frequency communication and large-scale antenna technology will be introduced in order to achieve the targets of 20Gbps for downlink transmission rate and 10Gbps for uplink transmission rate. High-frequency communication can provide wider system bandwidth, and the size of the antenna can be smaller, which is more beneficial to the deployment of large-scale antennas in base stations and User Equipment (UE). Multi-beam/Multi-TRP (Multi-beam/Multi-transmission node) transmission and reception at the base station side, and Multi-beam transmission and reception at the UE side will be widely applied. Taking NR PUSCH (New Radio Physical Uplink Sharing Channel) as an example, the Uplink may be multi-beam transmission. The beam identification mode comprises the following steps: a beam identification ID, an SSB (synchronization Signal Block) ID, and a CSI-RS (Channel State Information Reference Signal) ID.
A DC (Dual Connectivity) architecture may be adopted in the 5G system, and includes two Cell groups, namely, an MCG (Master Cell Group) corresponding to an MN (Master Node) on the network side and an SCG (Secondary Cell Group) corresponding to an SN (Secondary Node) on the network side. Specifically, the MCG includes a PCell (Primary Cell) and an SCell (Secondary Cell), the SCG includes a PSCell (Primary Secondary Cell) and an SCell, and the PCell and the PSCell may be collectively referred to as an SpCell (Special Cell).
In a 5G system, the UE may only support a relatively small operating Bandwidth (e.g. 5MHz), while a cell on the network side may support a relatively large Bandwidth (e.g. 100MHz), and the small Bandwidth Part of the large Bandwidth where the UE operates may be referred to as BWP (Bandwidth Part). From the UE configuration perspective, the BWP may be 1 cell or 1-cell BWP for different UE functions. The network side can configure the UE with 1 or more BWPs, and transform the BWP the UE can work by activating or deactivating the BWP.
When a downlink beam of the PCell of the UE fails, the UE may trigger a beam failure recovery request procedure (i.e., beam failure recovery request procedure). Specifically, the UE may send a random access preamble at the PCell, and wait for receiving feedback information of the Network side on the PCell, where the feedback information may be PDCCH (Physical Downlink Control Channel) information scheduled by a C-RNTI (Cell Radio Network Temporary Identifier); after receiving the feedback information of the network for the beam failure recovery request, the UE may determine that the (serving) beam corresponding to the PCell is recovered successfully.
However, when an SCell or BWP is introduced, the BWP may be a BWP under the PCell, or a BWP under the SCell, and a beam of the SCell or BWP may also have a beam failure, for which it is not yet clear how to perform beam failure recovery, so it is necessary to provide a beam failure recovery method for the SCell or BWP to clear how to recover a beam on the SCell or BWP when a beam failure occurs in the SCell or BWP.

Referring to fig. 1, an embodiment of the present invention provides a method for recovering a beam failure, which is applied to a terminal device, and includes the following steps:
step 101: and acquiring resource configuration information.
Wherein the resource configuration information is used for beam failure recovery of the SCell or the BWP. The BWP may be a BWP under a PCell or a BWP under an SCell.
Step 102: and when detecting that the beam on the SCell or the BWP fails, sending a beam failure request message to the network equipment at the corresponding resource position according to the resource configuration information.
The corresponding resource location may specifically be a cell, a BWP, a channel, etc. determined by the terminal device according to the resource configuration information.

For example, in a specific implementation, if the UE detects that the SCell activated by the UE does not broadcast the paging message to notify system information (that is, the beam on the SCell fails to generate a beam), the UE may send a beam failure request message to the base station and receive feedback information sent by the base station according to the acquired resource configuration information, change the activated SCell according to the feedback information, determine a beam for beam failure recovery, and receive the system information using the determined beam, where the UE and the base station keep consistent with each other for the SCell changed and activated by the UE, thereby avoiding data loss.
Or, if the UE detects that there is no paging message notifying system information broadcast on a BWP under its activated PCell (or SCell) (i.e., a beam on the BWP fails), the UE may send a beam failure request message to the base station and receive feedback information sent by the base station according to the acquired resource configuration information, change the activated BWP according to the feedback information, determine a beam for beam failure recovery, and receive the system information using the determined beam, where the UE and the base station keep consistent for the BWP changed and activated by the UE, thereby avoiding data loss.
