This application claims the priority of Chinese Patent Application No. 202010070190.X filed in China on January 21, 2020, the entire content of which is incorporated herein by reference.

Technical field

The present disclosure relates to the field of communication technologies, and in particular to a method for receiving and sending uplink data, network equipment and terminals.

Background technique

In order to increase the data transmission rate, the network may configure a secondary cell group (SCG) for user equipment or terminal (User Equipment, UE) to perform load sharing and increase the UE data transmission rate. After the network configures the SCG for the UE, the UE will access a secondary node (Secondary Node, SN) in a special cell (Special Cell, SpCell) of the SCG, that is, a primary SCG cell (Primary SCG Cell, PSCell). The network can configure bearer transmission for the UE in the SCG. The UE maintains the configuration information of the master cell group (Master cell group, MCG) and SCG at the same time.

In Release 17, the 5G NR system is expected to support SCG suspend or SCG dormant or PSCell suspend or sleep. It is intended for infrequent large data streams when there is no large data packet transmission. Suspend the SCG/PSCell or configure it to enter the sleep state. The UE and the network side save the SCG context, but stop some actions, such as stopping monitoring the physical downlink control channel (PDCCH) on the SCG side, and stop the SCG side Data transmission saves UE power consumption, and when there is a large data flow interaction, the SCG of the UE is quickly activated for data transmission. The NR system supports the inactive state (RRC INACTIVE). After the UE configured with the SCG enters the inactive state, the terminal and the network side will save the configuration information of the SCG.

The network can configure different forms of bearers for the UE. According to the location of the Packet Data Convergence Protocol (PDCP), the MCG termination bearer and SCG termination bearer can be configured, and according to the radio link control (Radio Link Control, RLC) bearer The position of can be configured with MCG RLC bearer, SCG RLC bearer, and split bearer.

As shown in Figure 1, the separate bearer means that the network configures the RLC bearer transmitted at the Master Node (MN) and the RLC bearer transmitted at the SN for the bearer, and the network configures the designated branch main path for the bearer. When the split bearer is configured with the duplication transmission function and is activated, the UE needs to transmit the same PDCP data packet at the MN and SN at the same time. If the repeated transmission function is not configured or the repeated transmission function is deactivated, the UE determines the data transmission path according to the configured uplink data separation threshold. When the buffer of the data to be transmitted is less than the configured threshold, the UE only transmits the data to be transmitted on the main path , When the buffer of data to be transmitted is greater than the configured threshold, the UE can choose to transmit data on any branch. For PDCP control protocol data unit (Protocol Data Unit, PDU) can only be transmitted on the main path. The network can configure separate bearers for data radio bearer (DRB) or signaling radio bearer (SRB).

For downlink data, when the network configures split (separated) bearers for the UE, the network side can decide whether to transmit downlink data on the MN side or the SN side according to the status of the SCG. For non-separated bearers, the network side can decide whether Activate the SCG/PSCell state or reconfigure the bearer type, but when the SCG/PSCell is configured to sleep or hang or the UE enters the inactive state, when the UE side has uplink data that needs to be transmitted on the SCG side, how should the UE perform uplink data? Transmission needs to be resolved.
