US 12,772,109 B2 · Multiple concatenation buffers at a packet data convergence protocol layer

Abstract

Methods, systems, and devices for wireless communications are described. The described techniques provide for a transmitting device to concatenate one or more sets of service data units (SDUs) at a packet data convergence protocol (PDCP) layer and perform PDCP processing on the concatenated SDUs. The transmitting device may identify multiple SDUs at the PDCP layer and may input the SDUs into one or more concatenation buffers of the transmitting device. The transmitting wireless device may use one or more concatenation buffers associated with respective configurations for concatenating SDUs. For example, the one or more concatenation buffers may each be configured to concatenate SDUs until reaching a threshold size, a concatenation timer expiring, or both. Additionally, or alternatively, the one or more concatenation buffers may be configured to concatenate SDUs according to a radio link control (RLC) entity, a quality of service (QoS) flow, or both.
