Abstract: Some aspects of this disclosure relate to apparatuses and methods for a user equipment (UE) to send a portion of a packet data unit (PDU) to a base station. A radio link control (RLC) layer of the UE generates a PDU and a truncation indicator, where the truncation indicator can indicate a set of truncation points of the PDU. A medium access control (MAC) layer determines whether an uplink transmission size based on an uplink grant is smaller than a first number of bytes included in the PDU. In response to a determination that the uplink transmission size is smaller than the first number of bytes, the MAC layer selects a truncation point from the set of truncation points indicated by the truncation indicator, and remove at least a portion of the PDU to generate a truncated PDU having a second number of bytes smaller than the uplink transmission size.

Abstract: Systems, methods, and circuitries are provided for using an application Layer 2 buffer for reordering out of sequence (OOS) packets when possible to reduce an amount of memory allocated to a baseband (BB) Layer 2 (L2) buffer. In one example, a baseband circuitry of a user equipment (UE), includes BB memory, configured as a BB L2 buffer and one or more BB processors. The BB processors are configured to receive an OOS packet from a physical layer; and in response to an APP L2 buffer status indicating at least a first amount of memory is available, send the OOS packet to APP circuitry for storing in an APP L2 buffer.
