US Patent 10405231 Switching between packet duplication operating modes

Techniques provided herein select an operating mode from a plurality of operating modes. Various implementations establish a radio bearer with at least one network entity over a network using a first Radio Link Control (RLC) protocol entity and a second RLC protocol entity. Various implementations determine whether packet duplication is enabled for the radio bearer by processing Packet Data Convergence Protocol (PDCP) configuration settings. In response to determining that packet duplication is enabled, various implementations duplicate uplink data packets over the network by submitting the uplink data packets to both the first RLC protocol entity and the second RLC entity. In response to determining that packet duplication is disabled and split bearer is enabled, various implementations select one of the first RLC protocol entity and the second RLC protocol entity for uplink data packet transmission.
