US 11,240,696 B2 · Measuring and verifying layer 2 sustained downlink maximum data rate decoding performance

Abstract

Test entity for verifying user equipment (UE) device layer 2 sustained downlink maximum data rate decoding performance may send a non-access stratum message to the UE device that requests activation of a downlink-only test mode, sending a first Packet Data Convergence Protocol (PDCP) status request to the UE device, send downlink PDCP packets to the UE device during a measurement interval, receive a physical layer (PHY) hybrid acknowledge request (HARQ) acknowledgement (ACK) or non-acknowledgement (NACK) from the UE device and determine expected missed layer 1 packets based on the received PHY HARQ ACK/NACK, send a second PDCP status request to the UE device after the measurement interval, receive a PDCP status report from the UE device, and determine missed layer 2 packets from a First Missing Count (FMC) value or bitmap included in the received PDCP status report.

Dependent claims

A method performed by a processor in a test entity for layer 2 sustained downlink maximum data rate decoding performance of a user equipment device, comprising:

sending to the user equipment device a non-access stratum (NAS) signaling message that requests at least one or more of:
activation of a new downlink-only test mode that does not loopback data to the test entity in an uplink;
or
activation of a modified downlink-only test mode that does not loopback data to the test entity in the uplink;
sending a first Packet Data Convergence Protocol (PDCP) status request to the user equipment device;
sending downlink PDCP packets to the user equipment device during a measurement interval after sending the first PDCP status request to the user equipment device;
receiving a physical layer (PHY) hybrid acknowledge request (HARQ) acknowledgement (ACK) or non-acknowledgement (NACK) from the user equipment device and determining expected missed layer 1 packets based on information included in the received PHY HARQ ACK/NACK;
sending a second PDCP status request to the user equipment device after the measurement interval;
receiving a PDCP status report from the user equipment device in response to the second PDCP status request;
and
determining missed layer 2 packets from a First Missing Count (FMC) value or bitmap included in the received PDCP status report.

send a second PDCP status request to the user equipment device after the measurement interval;
receive a PDCP status report from the user equipment device in response to the second PDCP status request;
and
determining missed layer 2 packets from a First Missing Count (FMC) value or bitmap included in the received PDCP status report.
