US 2025/0158752 A1 · RADIO LINK CONTROL ACKNOWLEDGEMENT MODE TIMING FOR MULTI MODAL TRAFFIC

Abstract

Methods, systems, and devices for wireless communications are described. A network may configure one or more devices with a timer. The timer may define a threshold amount of time a receiver in a radio link control (RLC) acknowledgement mode (AM) is to wait for and continue to request retransmission of a missing RLC packet data unit (PDU) through automatic repeat request (ARQ) mechanisms. The receiver may detect a missing PDU, and may initiate two timers: a first timer defining how long the receiver is to request and monitor for the missing first PDU, and a second timer defining an amount of time before requesting retransmission of the first PDU. Upon expiration of the second timer, the receiver may transmit a request for retransmission of the first PDU. Upon expiration of the first timer, the receiver may forward all other sequentially received PDUs to higher layers for decoding.

Dependent claims

A receiving device, comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the receiving device to:
receive control signaling indicating a first timer corresponding to a radio link control acknowledgement mode, the first timer indicating a threshold amount of time during which the receiving device is to request and monitor for one or more missed packet data units;
receive one or more packet data units of a first set of packet data units, each packet data unit of the first set of packet data units corresponding to a respective sequence number, wherein at least a first packet data unit is missing from the first set of packet data units;
initiate the first timer and a second timer upon detecting the first packet data unit is missing;
transmit, upon expiration of the second timer, a request for a retransmission of the first packet data unit according to the radio link control acknowledgement mode;
and
deliver the one or more packet data units to higher layers of the receiving device for decoding based at least in part on a failure to receive the first packet data unit and expiration of the first timer.
