Abstract:
Systems, methods, and devices are provided to: perform packet data convergence protocol (PDCP) deciphering of the packets to store deciphered packets in a common buffer; perform PDCP reordering of the deciphered packets in the common buffer to generated a stream or reordered packets; perform robust header compression (ROHC) decompression on the stream of reordered packets; and determine, based on a packet indication, to reset the ROHC decompression, wherein the packet indication comprises a single bit in a PDCP header set to indicate a start of ROHC reset based on a path switch during a handover from a source cell to a target cell.
