CN-121986531-A - Adaptive retransmission of non-terrestrial payloads

Abstract

A user equipment may receive a payload notification configuration from a network node, the payload notification configuration including a baseline notification priority level and a notification priority increment value associated with an identifier of a traffic flow. The user equipment may generate a status message to be transmitted according to the uplink control channel occasion resource, the status message including a status indication corresponding to a payload corresponding to a traffic flow received by the user equipment. The user equipment may prioritize the status indications in the status message according to the baseline notification priority indicated in the payload notification configuration and based on the capacity of the opportunistic resources for accommodating the status indications. The baseline notification priority corresponding to a status indication not included in a status message may be increased by a notification priority increment such that the status indication is prioritized higher in a next status message than another status indication corresponding to a higher baseline notification priority in a payload notification configuration.

Description

Adaptive retransmission of non-terrestrial payloads RELATED APPLICATIONS The present application claims priority from U.S. non-provisional patent application No. 18/490,567 filed on 10/19 of 2023, entitled "ADAPTIVE RETRANSMISSION OF NON-TERRESTRIAL PAYLOAD (adaptive retransmission of non-terrestrial payloads)", the entire contents of which are incorporated herein by reference. Background The term "new wireless" (NR) associated with the fifth generation mobile wireless communication system ("5G") refers to aspects of technology used in wireless radio access networks ("RANs") that include several quality of service classes ("QoS"), including ultra-reliable low-latency communications ("URLLC"), enhanced mobile broadband ("eMBB"), and mass machine type communications ("mMTC"). The URLLC QoS category is associated with stringent latency requirements (e.g., low latency or low signal/message delay) and high reliability of wireless performance, while conventional eMBB use cases may be associated with high capacity wireless communications, which may allow less stringent latency requirements (e.g., higher latency than URLLC) and less reliable wireless performance than URLLC. mMTC may have performance requirements lower than eMBB use case. Some use case applications involving mobile devices or mobile user devices (such as smartphones, wireless tablets, smartwatches, etc.) may be imposed on a changing given RAN resource load or demand. The RAN node may activate a network power saving mode to reduce power consumption.
