Abstract

The present application relates to a communication method and equipment, wherein a communication method includes: receiving first signaling, the first signaling is used to indicate that the first logical channel is deactivated; according to the logical channel in the activated state and the Whether the first logical channel belongs to the same MAC entity, determine whether the association relationship between the activated logical channel and the carrier is applicable, and the first logical channel and the activated logical channel belong to the same radio bearer, and the radio bearer is configured with a PDCP retransmission function. Through the method provided in the embodiment of the present application, after a logical channel is deactivated, it can be determined which carriers should be used by the remaining logical channels, so that the terminal device can perform correct operations.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] In the fifth generation mobile communication technology (the 5th generation, 5G) system, a packet data convergence protocol (packet data convergence protocol, PDCP) duplication transmission function is introduced. PDCP repeated transmission usually refers to duplicating the data packet of the radio bearer into two identical packets (that is, repeated packets) at the PDCP layer, and then submitting the two data packets to two different radio link control (radio link control) , RLC) entity for transmission, and then transmit to the media access control (media access control, MAC) layer through different logical channels. [0003] In order to ensure the reliability of data transmission, the original data packet and the copied data packet transmitted to the MAC layer cannot be transmitted on the sam...
