Description

Method, terminal equipment and network equipment for data processing

Technical Field

The present application relates to the field of communications, and in particular, to a method, a terminal device, and a network device for data processing.

Background

In a New Radio (NR) system, since the Radio Link Control (RLC) of the NR does not support in-sequence delivery, for any cases, such as an acknowledged/unacknowledged mode (AM/UM) of the RLC, a reordering timer is configured in a Packet Data Convergence Protocol (PDCP) bearer (SRB) or a Data Radio Bearer (DRB), and once the reordering timer expires, even if data does not arrive at a receiving end in sequence or an individual packet does not arrive at the receiving end (i.e., there is a packet loss), the reordering window is moved and the packet loss is ignored (even if the packet loss arrives at the receiving end later), so that the data is not transmitted to the receiving end.

This is possible for the NR RLC, since the NR RLC has no function of in-sequence delivery, and a reordering timer of the PDCP is necessary. However, for some cases, such as a dual connectivity architecture with Long Term Evolution (LTE) as the primary node and NR as the secondary node, NR PDCP may be used above LTE RLC, and for this case, the reordering function and the reordering timer in NRPDCP are duplicated with LTE RLC.

In this embodiment of the present application, the terminal device determines parameter information of an RLC entity, where the parameter information may include version information of the RLC entity, a mode in which the RLC entity is located, and a radio bearer type transmitted by the RLC entity to the PDCP entity.

In an embodiment of the present application, the parameter information may include version information of the RLC entity.

For another example, the network device may further transmit the parameter information to the terminal device, the parameter information indicating that the RLC entity in the UM mode in the terminal device is used for transmitting the DRB, and set the first reordering timer in the PDCP entity to 0. That is, the network device determines that the RLC entity of the terminal device in the UM mode is to be used for transmitting the DRB, and the first reordering timer configured by the network device according to the preset rule may be set to 0.

Optionally, as an embodiment, the parameter information may further indicate a radio bearer type sent by the RLC entity, for example, the RLC entity is used for transmitting the SRB.

For example, the terminal device may determine that the parameter information indicates that the RLC entity needs to send the SRB when the RLC entity needs to send the SRB, and set a first reordering timer in the PDCP entity to 0 according to a preset rule.

For example, the network device may send the parameter information to the terminal device, where the parameter information may indicate that the RLC entity is used for transmitting the SRB, and the terminal device sets a first reordering timer in the PDCP entity to 0 according to the parameter information and a preset rule.
