Wireless communication networks provide wireless data services to wireless user devices. Exemplary wireless data services include machine-control, internet-access, media-streaming, and social-networking. Exemplary wireless user devices comprise phones, computers, vehicles, robots, and sensors. The wireless communication networks have wireless access nodes which exchange wireless signals with the wireless user devices using wireless network protocols. Exemplary wireless network protocols include Fifth Generation New Radio (5GNR), Millimeter Wave (MMW), Long Term Evolution (LTE), Institute of Electrical and Electronic Engineers (IEEE) 802.11 (WIFI), and Low-Power Wide Area Network (LP-WAN). Many wireless user devices have batteries to supply power—especially while mobile. To conserve the often-limited battery power in the wireless user devices, the wireless access nodes implement Discontinuous Reception (DRX). With DRX, a wireless user device powers down its wireless receiver for an off-time and then powers-up the wireless receiver to check with the wireless access node for a data notice. When a data notice is received, the wireless user device keeps its wireless receiver powered-up to receive user data per the data notice. When no data notice is received, the wireless user device powers the wireless receiver down for the off-time. The length of the off-time has a direct relation to the amount of battery conservation and to the amount of data latency. Unfortunately, the wireless access nodes do not control DRX off-times for the wireless user devices to effectively balance battery conservation with service delivery.

Various examples of network operation and configuration are described herein. In some examples, UEs 102-103 and radio 121 wirelessly exchange user data over wireless links 112-113. Radio 121 and baseband circuitry 122 exchange the user data over interface links 114. Baseband circuitry 122 and network elements 130 exchange the user data over backhaul links 115. Network elements 130 and external systems exchange some of the user data over external links 116. Baseband circuitry 122 determines the data communication performance of backhaul links 115. For example, Baseband circuitry 122 may determine the average downlink throughput in megabits per second.
Baseband circuitry 122 selects a DRX schedule for UE 101 based on the data communication performance of backhaul links 115. The DRX schedule indicates when UE powers-up a wireless receiver to check network signaling and when UE 101 powers-down the wireless receiver to save battery power. The DRX schedule has additional rules to remain on when data notices and user data are received during an on-time. An exemplary DRX schedule is illustrated at the upper right. Typically, baseband circuitry 122 increases the DRX off-time for UE 101 in response to a decrease in backhaul performance. Baseband circuitry 122 typically decreases the DRX off-time for UE 101 in response to an increase in the backhaul performance. Baseband circuitry 122 transfers the DRX schedule to radio 121.

Advantageously, wireless access node 120 controls DRX off-times for UE 101 to effectively balance battery conservation with service delivery. When backhaul quality suffers, the DRX off-time is lengthened to save battery. When the backhaul quality improves, the DRX off-time is shortened. Wireless access node 120 may consider additional factors like the radio channel size and channel occupancy when selecting the DRX schedule. In some examples, wireless access node has another radio that uses another frequency band, and baseband circuitry 122 controls DRX for UE 101 over the other radio in a similar manner. Baseband circuitry 122 could independently control the DRX of multiple additional radios.

In 5GNR radios 421-422, the antennas receive wireless 5GNR signals from UE 401 that transport uplink 5GNR signaling and data. The antennas transfer corresponding electrical uplink signals through duplexers to the amplifiers. The amplifiers boost the electrical uplink signals for filters which attenuate unwanted energy. Demodulators down-convert the filtered uplink signals from their carrier frequency. The analog/digital interfaces convert the demodulated analog uplink signals into digital uplink signals for the DSPs. The DSPs recover uplink 5GNR symbols from the uplink digital signals. In 5GNR BBU 423, the CPU executes the network applications to process the uplink 5GNR symbols and recover the uplink 5GNR signaling and the uplink 5GNR data. The network applications process the uplink 5GNR signaling and downlink Fifth Generation Core (5GC) signaling to generate new uplink 5GC signaling, new downlink 5GNR signaling, and new X2 signaling.

In 5GNR radios 421-422, the DSP processes the downlink 5GNR symbols to generate corresponding digital signals for the analog-to-digital interfaces. The analog-to-digital interfaces convert the digital signals into analog signals for modulation. Modulation up-converts the analog signals to their carrier frequency. The amplifiers boost the modulated signals for the filters which attenuate unwanted out-of-band energy. The filters transfer the filtered electrical signals through duplexers to the antennas.

NFVI 430 and external systems exchange some of the user data over external links. 5GNR BBU 423 determines the running average of the downlink throughput for the backhaul links. BBU 423 also determines the radio channel sizes and radio channel occupancies for 5GNR radios 421-422.
5GNR BBU 423 selects a DRX schedule for UE 401 over 5GNR radio 421 based on the backhaul performance, channel size, and channel occupancy for 5GNR radio 421. BBU 423 selects another DRX schedule for UE 401 over 5GNR radio 422 based on the backhaul performance, channel size, and channel occupancy for 5GNR radio 422. BBU 423 transfers the DRX schedule for radio 5GNR 401 to radio 421 and transfers the other DRX schedule for radio 5GNR 422 to radio 422. 5GNR radios 421-422 wirelessly transfers their respective DRX schedules to UE 401. UE 401 powers on and powers off wireless 5GNR receivers in radios 421-422 per their individual DRX schedules. The 5GNR transmitters in radios 421-422 are powered down and remain so until needed.
5GNR BBU 423 increases the DRX off-time for UE 401 in response to declining backhaul performance, smaller channel size, and/or higher channel occupancy. BBU 423 decreases DRX off-time for UE 401 in response to improving backhaul performance, larger channel size, and/or lower channel occupancy. Some factors may offset each other like when large channel size is offset by poor backhaul performance and the DRX off-time may stay the same. The DRX schedules have other timing rules in addition to the off-time that may be selected in a similar manner. The backhaul performance for 5GNR radios 421-422 is typically the same as they often share backhaul links, although backhaul performance for 5GNR radios 421-422 may be individually measured and will differ in some scenarios. The radio channel sizes may be the same or be different, and the channel occupancies typically differ by some margin based on respective live UE loading.
NFVI 430 receives user data for delivery to UE 401. NFVI 430 transfers the user data to 5GNR BBU 423. 5GNR BBU 423 waits for UE 401 to receive per one of the DRX schedules. When UE 101 is receiving per one of the DRX schedules, BBU 423 transfers a data notice to one of radios 421-422. In some examples, BBU 423 waits for UE 401 to receive over a specific one of radios 421-422 that is used for a given data service that is associated with the user data. The corresponding one of radios 421-422 wirelessly transfers the data notice to UE 401. UE 401 wirelessly receives the data notice per the pertinent DRX schedule for the corresponding one of radios 421-422. BBU 423 then transfers the user data for UE 401 to the corresponding one of radios 421-422 per the pertinent DRX schedule and the data notice. The corresponding one of radios 421-422 wirelessly transmits the user data to UE 401. UE 401 wirelessly receives the user data per the pertinent DRX schedule and the data notice.
