Embodiment approach 1

[0143] This embodiment mainly describes a specific method for the UE to generate an ROHC feedback packet or not generate an ROHC feedback packet based on the ROHC feedback information.

[0144] In step 11, the UE executes a dual connectivity mobility management procedure (for example, dual connectivity handover or dual connectivity SCG change) according to the instruction of the network device. In the process of performing dual connectivity mobility management, when the receiving PDCP entity of the UE receives downlink data, the UE may submit the downlink data to the corresponding ROHC decompression configuration according to specific information. (For example, in the process of handover or SCG change, the same PDCP entity for the UE can receive downlink data from the source node and the target node, if the downlink data comes from the source node, then submit the downlink data to the ROHC corresponding to the source node for decompression Configuration 1, if the downlink data...

Embodiment approach 2

[0155] This embodiment mainly describes a specific method for the UE to discard the ROHC feedback packet or not to discard the ROHC feedback packet based on the ROHC feedback information.

[0156] In step 21, the UE executes a dual connectivity mobility management process (such as dual connectivity handover or dual connectivity SCG change) according to the instruction of the network device. In the process of performing dual connectivity mobility management, when the receiving PDCP entity of the UE receives downlink data, the UE may submit the downlink data to the corresponding ROHC decompression configuration according to specific information. (For example, in the process of handover or SN change, the same PDCP entity for the UE can receive downlink data from the source node and the target node, if the downlink data comes from the source node, then submit the downlink data to the ROHC corresponding to the source node for decompression Configuration 1, if the downlink data come...

Embodiment approach 3

[0167] This embodiment mainly describes the specific method for the UE to send the ROHC feedback packet or not send the ROHC feedback packet based on the ROHC feedback information.

[0168] In step 31, the UE executes a dual connectivity mobility management procedure (for example, dual connectivity handover or dual connectivity SCG change) according to the instruction of the network device. In the process of performing dual connectivity mobility management, when the receiving PDCP entity of the UE receives downlink data, the UE may submit the downlink data to the corresponding ROHC decompression configuration according to specific information. (For example, in the process of handover or SN change, the same PDCP entity for the UE can receive downlink data from the source node and the target node, if the downlink data comes from the source node, then submit the downlink data to the ROHC corresponding to the source node for decompression Configuration 1, if the downlink data come...

Abstract

The embodiment of the invention discloses an ROHC feedback processing method and user equipment, relates to the technical field of communication, and can solve the problem that the compression efficiency is reduced due to the fact that the UE sends an ROHC feedback packet on a path not supporting uplink data transmission. The method comprises the steps that UE executes operation according to a target mode corresponding to target information based on ROHC feedback information; wherein the ROHC feedback information is generated after the downlink data head is decompressed through ROHC decompression configuration, and the ROHC feedback information is used for indicating the decompression state of a data packet in the downlink data; wherein the target information is used for indicating a pathconversion opportunity and a first node, the path conversion opportunity is an uplink path conversion opportunity of the UE, and the first node is a node corresponding to ROHC decompression configuration. The embodiments of the present invention are applied to a process in which a UE performs ROHC feedback processing.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to an ROHC feedback processing method and user equipment. Background technique [0002] In the process of dual connectivity mobility (for example, handover or secondary cell group (SCG) change), user equipment (user equipment, UE) can establish a connection at the source node and the target node at the same time, in this case, the UE can Simultaneously receive downlink data sent from the source node and the target node. [0003] Usually, when the downlink data received by the UE is configured with a robust header compression (robust header compression, ROHC) function, the UE can perform header decompression processing on the downlink data through ROHC decompression configuration, and generate ROHC feedback information, and then generate ROHC An ROHC feedback packet corresponding to the feedback information (for example, a packet data convergence ...
