Problems solved by technology

However, since the PDCP layer is located at the top layer of the wireless user plane protocol stack, PDCP packets and PDCP duplicate packets cannot be guaranteed to be sent through the two underlying carriers, which brings about a problem: if the signal quality on one carrier is very poor and the PDCP packet and PDCP replication packets are sent on this carrier, the probability of successful transmission will be very low

Abstract

The present disclosure relates to a function configuration method and device, a message sending method and device, user equipment, a base station, and a computer-readable storage medium. Wherein, the function configuration method includes: receiving a radio resource control RRC message sent by the base station, the RRC message carries configuration information, and the configuration information indicates that two radio link control RLC entities are configured for the data bearer DRB or the signaling bearer SRB, and the following Any item: data packet convergence protocol PDCP packet copy function, distribution function; configure two RLC entities for the DRB or SRB according to the RRC message, and any of the following: PDCP packet copy function, distribution function. The present disclosure configures two RLC entities and any one of the PDCP packet replication function and distribution function for the DRB or SRB according to the received RRC message, so that one DRB or SRB can only configure one of the PDCP packet replication function and distribution function at the same time. function.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to a function configuration method and device, a message sending method and device, user equipment, a base station, and a computer-readable storage medium. Background technique [0002] At present, the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) is carrying out the standardization work on the fifth generation mobile communication technology (5th Generation, referred to as 5G) new radio interface (new radio, referred to as NR), in order to To solve the reliability problem of data packet or signaling packet transmission, 3GPP has adopted a packet duplication scheme at the user plane packet data convergence protocol (PDCP for short) layer. However, since the PDCP layer is located at the top layer of the wireless user plane protocol stack, PDCP packets and PDCP duplicate packets cannot be guaranteed to be sent throu...
