DETAILED DESCRIPTION

Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. One skilled in the art should appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently of or combined with any other aspect of the disclosure. For example, an apparatus may be implemented or a method may be practiced using any number of the aspects set forth herein. In addition, the scope of the disclosure is intended to cover such an apparatus or method which is practiced using other structure, functionality, or structure and functionality in addition to or other than the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

Several aspects of telecommunication systems will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, or the like (collectively referred to as “elements”). These elements may be implemented using hardware, software, or combinations thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

While aspects may be described herein using terminology commonly associated with a 5G or New Radio (NR) radio access technology (RAT), aspects of the present disclosure can be applied to other RATs, such as a 3G RAT, a 4G RAT, and/or a RAT subsequent to 5G (e.g., 6G).

FIG.1is a diagram illustrating an example of a wireless network100, in accordance with the present disclosure. The wireless network100may be or may include elements of a 5G (e.g., NR) network and/or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network100may include one or more base stations110(shown as a BS110a, a BS110b, a BS110c, and a BS110d), a user equipment (UE)120or multiple UEs120(shown as a UE120a, a UE120b, a UE120c, a UE120d, and a UE120e), and/or other network entities. A base station110is an entity that communicates with UEs120. A base station110(sometimes referred to as a BS) may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, and/or a transmission reception point (TRP). Each base station110may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” can refer to a coverage area of a base station110and/or a base station subsystem serving this coverage area, depending on the context in which the term is used.

A base station110may provide communication coverage for a macro cell, a pico cell, a femto cell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs120with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs120with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs120having association with the femto cell (e.g., UEs120in a closed subscriber group (CSG)). A base station110for a macro cell may be referred to as a macro base station. A base station110for a pico cell may be referred to as a pico base station. A base station110for a femto cell may be referred to as a femto base station or an in-home base station. In the example shown inFIG.1, the BS110amay be a macro base station for a macro cell102a, the BS110bmay be a pico base station for a pico cell102b, and the BS110cmay be a femto base station for a femto cell102c. A base station may support one or multiple (e.g., three) cells.

In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a base station110that is mobile (e.g., a mobile base station). In some examples, the base stations110may be interconnected to one another and/or to one or more other base stations110or network nodes (not shown) in the wireless network100through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network.

The wireless network100may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a base station110or a UE120) and send a transmission of the data to a downstream station (e.g., a UE120or a base station110). A relay station may be a UE120that can relay transmissions for other UEs120. In the example shown inFIG.1, the BS110d(e.g., a relay base station) may communicate with the BS110a(e.g., a macro base station) and the UE120din order to facilitate communication between the BS110aand the UE120d. A base station110that relays communications may be referred to as a relay station, a relay base station, a relay, or the like.

The wireless network100may be a heterogeneous network that includes base stations110of different types, such as macro base stations, pico base stations, femto base stations, relay base stations, or the like. These different types of base stations110may have different transmit power levels, different coverage areas, and/or different impacts on interference in the wireless network100. For example, macro base stations may have a high transmit power level (e.g., 5 to 40 watts) whereas pico base stations, femto base stations, and relay base stations may have lower transmit power levels (e.g., 0.1 to 2 watts).

A network controller130may couple to or communicate with a set of base stations110and may provide coordination and control for these base stations110. The network controller130may communicate with the base stations110via a backhaul communication link. The base stations110may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link.

The UEs120may be dispersed throughout the wireless network100, and each UE120may be stationary or mobile. A UE120may include, for example, an access terminal, a terminal, a mobile station, and/or a subscriber unit. A UE120may be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, and/or any other suitable device that is configured to communicate via a wireless medium.

Some UEs120may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE and/or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and/or a location tag, that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs120may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs120may be considered a Customer Premises Equipment. A UE120may be included inside a housing that houses components of the UE120, such as processor components and/or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.

In general, any number of wireless networks100may be deployed in a given geographic area. Each wireless network100may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, or the like. A frequency may be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

In some examples, two or more UEs120(e.g., shown as UE120aand UE120e) may communicate directly using one or more sidelink channels (e.g., without using a base station110as an intermediary to communicate with one another). For example, the UEs120may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, a UE120may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station110.

Devices of the wireless network100may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, or the like. For example, devices of the wireless network100may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that although a portion of FR1 is greater than 6 GHz, FR1 is often referred to (interchangeably) as a “Sub-6 GHz” band in various documents and articles. A similar nomenclature issue sometimes occurs with regard to FR2, which is often referred to (interchangeably) as a “millimeter wave” band in documents and articles, despite being different from the extremely high frequency (EHF) band (30 GHz-300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band.

The frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified an operating band for these mid-band frequencies as frequency range designation FR3 (7.125 GHz-24.25 GHz). Frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics, and thus may effectively extend features of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHz), and FR5 (114.25 GHz-300 GHz). Each of these higher frequency bands falls within the EHF band.

With the above examples in mind, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. Further, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and/or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and/or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges.

In some aspects, the UE120may include a communication manager140. As described in more detail elsewhere herein, the communication manager140may receive, in an active state, a set of downlink grants or a set of uplink grants; and transition from the active state to an inactive state based at least in part on satisfaction of a set of threshold conditions during the active state, the set of threshold conditions including at least one of a quantity of downlink grants in the set of downlink grants, a quantity of uplink grants in the set of uplink grants, or an inactivity time. Additionally, or alternatively, the communication manager140may perform one or more other operations described herein.

In some aspects, a network entity (e.g., the base station110) may include a communication manager150. As described in more detail elsewhere herein, the communication manager150may transmit configuration information identifying a configuration for transition between an active state and an inactive state in a discontinuous reception mode, the configuration information identifying a configuration relating to a set of threshold conditions, the set of threshold conditions including at least one of a quantity of downlink grants in the set of downlink grants, a quantity of uplink grants in the set of uplink grants, or an inactivity time; and transmit, in an active state, a set of downlink grants or a set of uplink grants. Additionally, or alternatively, the communication manager150may perform one or more other operations described herein.

As indicated above,FIG.1is provided as an example. Other examples may differ from what is described with regard toFIG.1.

FIG.2is a diagram illustrating an example200of a base station110in communication with a UE120in a wireless network100, in accordance with the present disclosure. The base station110may be equipped with a set of antennas234athrough234t, such as T antennas (T≥1). The UE120may be equipped with a set of antennas252athrough252r, such as R antennas (R≥1).

At the base station110, a transmit processor220may receive data, from a data source212, intended for the UE120(or a set of UEs120). The transmit processor220may select one or more modulation and coding schemes (MCSs) for the UE120based at least in part on one or more channel quality indicators (CQIs) received from that UE120. The base station110may process (e.g., encode and modulate) the data for the UE120based at least in part on the MCS(s) selected for the UE120and may provide data symbols for the UE120. The transmit processor220may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor220may generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor230may perform spatial processing (e.g., precoding) on the data symbols, the control symbols, the overhead symbols, and/or the reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems232(e.g., T modems), shown as modems232athrough232t. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem232. Each modem232may use a respective modulator component to process a respective output symbol stream (e.g., for OFDM) to obtain an output sample stream. Each modem232may further use a respective modulator component to process (e.g., convert to analog, amplify, filter, and/or upconvert) the output sample stream to obtain a downlink signal. The modems232athrough232tmay transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas234(e.g., T antennas), shown as antennas234athrough234t.

At the UE120, a set of antennas252(shown as antennas252athrough252r) may receive the downlink signals from the base station110and/or other base stations110and may provide a set of received signals (e.g., R received signals) to a set of modems254(e.g., R modems), shown as modems254athrough254r. For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem254. Each modem254may use a respective demodulator component to condition (e.g., filter, amplify, downconvert, and/or digitize) a received signal to obtain input samples. Each modem254may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector256may obtain received symbols from the modems254, may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor258may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE120to a data sink260, and may provide decoded control information and system information to a controller/processor280. The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and/or a CQI parameter, among other examples. In some examples, one or more components of the UE120may be included in a housing284.

The network controller130may include a communication unit294, a controller/processor290, and a memory292. The network controller130may include, for example, one or more devices in a core network. The network controller130may communicate with the base station110via the communication unit294.

One or more antennas (e.g., antennas234athrough234tand/or antennas252athrough252r) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and/or one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components ofFIG.2.

On the uplink, at the UE120, a transmit processor264may receive and process data from a data source262and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) from the controller/processor280. The transmit processor264may generate reference symbols for one or more reference signals. The symbols from the transmit processor264may be precoded by a TX MIMO processor266if applicable, further processed by the modems254(e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the base station110. In some examples, the modem254of the UE120may include a modulator and a demodulator. In some examples, the UE120includes a transceiver. The transceiver may include any combination of the antenna(s)252, the modem(s)254, the MIMO detector256, the receive processor258, the transmit processor264, and/or the TX MIMO processor266. The transceiver may be used by a processor (e.g., the controller/processor280) and the memory282to perform aspects of any of the methods described herein (e.g., with reference toFIGS.6-10).

At the base station110, the uplink signals from UE120and/or other UEs may be received by the antennas234, processed by the modem232(e.g., a demodulator component, shown as DEMOD, of the modem232), detected by a MIMO detector236if applicable, and further processed by a receive processor238to obtain decoded data and control information sent by the UE120. The receive processor238may provide the decoded data to a data sink239and provide the decoded control information to the controller/processor240. The base station110may include a communication unit244and may communicate with the network controller130via the communication unit244. The base station110may include a scheduler246to schedule one or more UEs120for downlink and/or uplink communications. In some examples, the modem232of the base station110may include a modulator and a demodulator. In some examples, the base station110includes a transceiver. The transceiver may include any combination of the antenna(s)234, the modem(s)232, the MIMO detector236, the receive processor238, the transmit processor220, and/or the TX MIMO processor230. The transceiver may be used by a processor (e.g., the controller/processor240) and the memory242to perform aspects of any of the methods described herein (e.g., with reference toFIGS.6-10).

The controller/processor240of the base station110, the controller/processor280of the UE120, and/or any other component(s) ofFIG.2may perform one or more techniques associated with discontinuous reception (DRX) in jitter-affected scenarios, as described in more detail elsewhere herein. In some aspects, the network entity described herein is the base station110, is included in the base station110, or includes one or more components of the base station110shown inFIG.2. For example, the controller/processor240of the base station110, the controller/processor280of the UE120, and/or any other component(s) ofFIG.2may perform or direct operations of, for example, process700ofFIG.7, process800ofFIG.8, and/or other processes as described herein. The memory242and the memory282may store data and program codes for the base station110and the UE120, respectively. In some examples, the memory242and/or the memory282may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station110and/or the UE120, may cause the one or more processors, the UE120, and/or the base station110to perform or direct operations of, for example, process700ofFIG.7, process800ofFIG.8, and/or other processes as described herein. In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples.

In some aspects, the UE120includes means for receiving, in an active state, a set of downlink grants or a set of uplink grants; and/or means for transitioning from the active state to an inactive state based at least in part on satisfaction of a set of threshold conditions during the active state, the set of threshold conditions including at least one of a quantity of downlink grants in the set of downlink grants, a quantity of uplink grants in the set of uplink grants, or an inactivity time. The means for the UE120to perform operations described herein may include, for example, one or more of communication manager140, antenna252, modem254, MIMO detector256, receive processor258, transmit processor264, TX MIMO processor266, controller/processor280, or memory282.

In some aspects, a network entity (e.g., the base station110) includes means for transmitting configuration information identifying a configuration for transition between an active state and an inactive state in a discontinuous reception mode, the configuration information identifying a configuration relating to a set of threshold conditions, the set of threshold conditions including at least one of a quantity of downlink grants in the set of downlink grants, a quantity of uplink grants in the set of uplink grants, or an inactivity time; and/or means for transmitting, in an active state, a set of downlink grants or a set of uplink grants. In some aspects, the means for the network entity to perform operations described herein may include, for example, one or more of communication manager150, transmit processor220, TX MIMO processor230, modem232, antenna234, MIMO detector236, receive processor238, controller/processor240, memory242, or scheduler246.

While blocks inFIG.2are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor264, the receive processor258, and/or the TX MIMO processor266may be performed by or under the control of the controller/processor280.

As indicated above,FIG.2is provided as an example. Other examples may differ from what is described with regard toFIG.2.

FIG.3is a diagram illustrating an example300of an O-RAN architecture, in accordance with the present disclosure. As shown inFIG.3, the O-RAN architecture may include a control unit (CU)310that communicates with a core network320via a backhaul link. Furthermore, the CU310may communicate with one or more DUs330via respective midhaul links. The DUs330may each communicate with one or more RUs340via respective fronthaul links, and the RUs340may each communicate with respective UEs120via radio frequency (RF) access links. The DUs330and the RUs340may also be referred to as O-RAN DUs (O-DUs)330and O-RAN RUs (O-RUs)340, respectively.

In some aspects, the DUs330and the RUs340may be implemented according to a functional split architecture in which functionality of a base station110(e.g., an eNB or a gNB) is provided by a DU330and one or more RUs340that communicate over a fronthaul link. Accordingly, as described herein, a base station110may include a DU330and one or more RUs340that may be co-located or geographically distributed. In some aspects, the DU330and the associated RU(s)340may communicate via a fronthaul link to exchange real-time control plane information via a lower layer split (LLS) control plane (LLS-C) interface, to exchange non-real-time management information via an LLS management plane (LLS-M) interface, and/or to exchange user plane information via an LLS user plane (LLS-U) interface.

Accordingly, the DU330may correspond to a logical unit that includes one or more base station functions to control the operation of one or more RUs340. For example, in some aspects, the DU330may host a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more high physical (PHY) layers (e.g., forward error correction (FEC) encoding and decoding, scrambling, and/or modulation and demodulation) based at least in part on a lower layer functional split. Higher layer control functions, such as a packet data convergence protocol (PDCP), radio resource control (RRC), and/or service data adaptation protocol (SDAP), may be hosted by the CU310. The RU(s)340controlled by a DU330may correspond to logical nodes that host RF processing functions and low-PHY layer functions (e.g., fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, and/or physical random access channel (PRACH) extraction and filtering) based at least in part on the lower layer functional split. Accordingly, in an O-RAN architecture, the RU(s)340handle all over the air (OTA) communication with a UE120, and real-time and non-real-time aspects of control and user plane communication with the RU(s)340are controlled by the corresponding DU330, which enables the DU(s)330and the CU310to be implemented in a cloud-based RAN architecture.

As indicated above,FIG.3is provided as an example. Other examples may differ from what is described with regard toFIG.3.

FIG.4is a diagram illustrating an example400of a discontinuous reception (DRX) configuration, in accordance with the present disclosure. Examples of DRX configurations include idle mode DRX (I-DRX) and connected mode DRX, which may also be referred to as connected DRX (CDRX) or enhanced or evolved CDRX (eCDRX). Additional details regarding DRX configurations are described with regard to, for example, 3GPP Technical Specification (TS) 36.321, Release 17, Version 17.0.0.

As shown inFIG.4, a base station110may transmit a DRX configuration to a UE120to configure a DRX cycle405(e.g., a CDRX cycle) for the UE120. A DRX cycle405may include a DRX on duration410(e.g., during which a UE120is awake or in an active state) and an opportunity to enter a DRX sleep state415. As used herein, the time during which the UE120is configured to be in an active state (or awake state) during the DRX on duration410may be referred to as an active time or an awake time, and the time during which the UE120is configured to be in the DRX sleep state415(or inactive state or off duration) may be referred to as an inactive time or a sleep time. As described below, the UE120may monitor a physical downlink control channel (PDCCH) during the active time, and may refrain from monitoring the PDCCH during the inactive time.

During the DRX on duration410(e.g., the active time), the UE120may monitor a downlink control channel (e.g., a PDCCH), as shown by reference number420. For example, the UE120may monitor the PDCCH for downlink control information (DCI) pertaining to the UE120. If the UE120does not detect and/or successfully decode any PDCCH communications intended for the UE120during the DRX on duration410, then the UE120may enter the sleep state415(e.g., for the inactive time) at the end of the DRX on duration410, as shown by reference number425. In the sleep state415, the UE120may deactivate one or more antennas or antenna panels, processors, or other components (e.g., that are active when the UE120is in on duration410) to reduce power consumption. In this way, the UE120may conserve battery power and reduce power consumption. As shown, the DRX cycle405may repeat with a configured periodicity according to the DRX configuration.

If the UE120detects and/or successfully decodes a PDCCH communication intended for the UE120, then the UE120may remain in an active state (e.g., awake) for the duration of a DRX inactivity timer430(e.g., which may extend the active time). The UE120may start the DRX inactivity timer430at a time at which the PDCCH communication is received (e.g., in a transmission time interval (TTI) in which the PDCCH communication is received, such as a slot or a subframe). The UE120may remain in the active state until the DRX inactivity timer430expires, at which time the UE120may enter the sleep state415(e.g., for the inactive time), as shown by reference number435. During the duration of the DRX inactivity timer430, the UE120may continue to monitor for PDCCH communications, may obtain a downlink data communication (e.g., on a downlink data channel, such as a physical downlink shared channel (PDSCH)) scheduled by the PDCCH communication, and/or may prepare and/or transmit an uplink communication (e.g., on a physical uplink shared channel (PUSCH)) scheduled by the PDCCH communication. The UE120may restart the DRX inactivity timer430after each detection of a PDCCH communication for the UE120for an initial transmission (e.g., but not for a retransmission). By operating in this manner, the UE120may conserve battery power and reduce power consumption by entering the sleep state415. Although some aspects are described herein in terms of monitoring for a PDCCH communication, other downlink communications are contemplated.

As indicated above,FIG.4is provided as an example. Other examples may differ from what is described with respect toFIG.4.

FIG.5is a diagram illustrating an example500of CDRX operation in a jitter-affected scenario, in accordance with the present disclosure.

As shown inFIG.5, CDRX operation may include a set of CDRX on durations, in which a UE is configured to receive downlink transmissions, and a set of CDRX off durations, in which the UE is in a power saving mode and is not configured to receive downlink transmissions. Jitter, which may also be referred to as “network jitter,” is a variation in time delay between when a signal is transmitted (and scheduled to be received) and when the signal is actually received. Jitter can be a result of network congestion (e.g., insufficient bandwidth for communications occurring on a network), poor hardware performance (e.g., of devices associated with relaying, processing, and transmitting packets), or poor connection quality (e.g., high interference or low signal-to-interference-and-noise-ratio (SINR)), among other examples. Jitter can impact communications by causing packets to be received outside of a monitoring time of a device. For example, jitter can cause a packet to be delayed to outside of a CDRX on duration, which may result in the packet being queued by the network (e.g., one or more network entities) until a next CDRX on duration. Queuing the packet may result in an increased transmission delay.

As shown, a packet arrival time, with jitter taken into account, can be represented as a probabilistic distribution (e.g., for traffic sources that send packets with a fixed periodicity), such as a bell curve (which may also be referred to as a “normal curve”). A timing of CDRX on durations and CDRX off durations can be configured to increase a likelihood of packet receipt in jitter scenarios. For example, the CDRX on duration can be configured (e.g., by a network entity) to include a high percentile of a downlink packet arrival probability, which provides low latency by enabling immediate scheduling for downlink packets. This can result in longer CDRX on durations being configured for high jitter scenarios to encompass wider probabilistic distributions associated with higher levels of jitter.

As shown by reference numbers510and520, when packets are received in a first CDRX on duration and a second CDRX on duration, respectively, an inactivity timer is started. The inactivity timer is associated with indicating whether there are further packets for a UE to receive. However, when the inactivity timer expires, the UE still remains in the CDRX on duration until the CDRX on duration is scheduled to expire. As a result, the UE may continue using excess power resources, even after the UE has finished receiving all packets that were scheduled for the UE, until the CDRX on duration is over and the UE can transition to a power saving mode associated with a CDRX off duration.

As indicated above,FIG.5is provided as an example. Other examples may differ from what is described with respect toFIG.5.

As described above, jitter can result in a probabilistic distribution for a time position in which a periodic data burst (e.g., a set of packets) can be received by a UE. In extended reality (XR) applications with 48 frames per second (FPS), an interval between frames (e.g., from a start of a first frame to a start of a second frame) is configured to be approximately 1/48 of a second (20.83 milliseconds (ms), but jitter can result in an actual interval between frames being smaller or larger than the configured 20.83 ms (e.g., the actual interval can be in a range of 10 ms and to 30 ms). A CDRX cycle length can be configured to be equal to a traffic periodicity of an application, which may provide power saving while minimizing packet latency. However, when jitter is present, an active part of a CDRX cycle (e.g., the CDRX on duration) needs to be configured to be long enough to cover a tail of the probabilistic distribution for receiving a periodic data burst. In other words, although the interval between frames of XR data is approximately 20 ms, the CDRX on duration may be configured to cover an extra 10 ms in case jitter results in the actual interval being 30 ms for some data bursts corresponding to some frames. This extension of the CDRX on duration increases UE power consumption by causing the UE to remain in an active state longer than is necessary (e.g., in cases where the actual interval is less than 30 ms). Without jitter, a CDRX on duration can be configured to be as small as possible such that a network has allocated available resources to initiate transmission of a data burst within the CDRX on duration (e.g., the CDRX on duration could be only 1 ms to cover 1 ms of data burst). However, with jitter, to ensure data delivery without excessive queuing, the CDRX on duration is configured based on the tail of the aforementioned probability distribution (e.g., to account for the jitter), rather than on an expected availability of resources to schedule data. As a result, jitter scenarios can result in a less efficient use of network resources than may occur in non-jitter scenarios.

Some aspects described herein enable early CDRX state transitioning for jitter-affected scenarios. For example, when a UE determines that one or more threshold conditions are satisfied, the UE may transition from an active state to an inactive state (e.g., before the UE is scheduled to transition from the active state to the inactive state), thereby enabling the UE to enter a power saving mode earlier than if the UE waited until the UE was scheduled to transition from the active state to the inactive state. In other words, when the UE has received a threshold quantity of grants (in a set of grants) (e.g., uplink grants or downlink grants) and/or an inactivity timer is expired (indicating that the UE has finished receiving a complete data burst for the CDRX on duration), the UE may transition to an inactive state before the 30 ms has expired, rather than wait for the full 30 ms to expire, as described above. In this way, the UE reduces power consumption without negatively impacting latency for, for example, communications applications that include periodic, short burst traffic patterns, such as XR, virtual reality (VR), augmented reality (AR), or Voice over Internet Protocol (VoIP), among other examples.

FIG.6is a diagram illustrating an example600associated with CDRX operation in a jitter-affected scenario, in accordance with the present disclosure. As shown inFIG.6, example600may include a UE120communicating with a network entity602in a CDRX mode.

As further shown inFIG.6, and by reference number610, the UE120may receive, from the network entity602, configuration information identifying a configuration for a set of threshold conditions. For example, the UE120may receive information identifying the set of threshold conditions, such as which conditions to use to cause an early state transition (e.g., an early transition to a CDRX off duration). Additionally, or alternatively, the UE120may receive information identifying a value for one or more threshold conditions. For example, the UE120may receive information identifying a minimum quantity of downlink grants that the UE120is to receive before an early state transition. Additionally, or alternatively, the UE120may receive information identifying a minimum quantity of uplink grants before an early state transition. Additionally, or alternatively, the UE120may receive information identifying a length of an inactivity timer (e.g., a quantity of slots).

In some aspects, network entity602may provide information identifying values for the one or more threshold conditions, when may enable the UE120to derive which threshold conditions to evaluate. For example, when the UE120does not receive a value for a threshold condition, the UE120may determine not to evaluate the condition (the condition is always satisfied). Similarly, when the UE120receives a value of 0 (e.g., for the quantity of uplink or downlink grants) the UE120may determine not to evaluate the condition (the condition is always satisfied). Although some aspects are described herein in terms of a particular set of threshold conditions, other threshold conditions may be possible. In some aspects, the UE120may use stored or static configuration information for the set of threshold conditions (e.g., rather than receiving configuration information from network entity602).

As further shown inFIG.6, and by reference numbers620and630, the UE120may communicate with the network entity602during a CDRX on duration and determine whether the set of threshold conditions are satisfied. For example, the UE120may receive a burst transmission of a set of packets during the on duration. In this case, the UE120may determine whether a quantity of uplink grants satisfies a threshold, a quantity of downlink grants satisfies a threshold, and/or an inactivity timer is elapsed (e.g., the UE120may determine whether one or all of the threshold conditions are satisfied based at least in part on a configuration for the set of threshold conditions).

In some aspects, based at least in part on the set of threshold conditions being satisfied, the UE120may transition from an active state associated with a CDRX on duration to an inactive state associated with a CDRX off duration before the CDRX off duration is scheduled to start. For example, as shown by reference numbers640and640′, after expiration of the inactivity timer that is started when the UE120receives a packet burst, and/or after satisfaction of one or more other threshold conditions, the UE120may transition to the inactive state. In this case, the UE120transitions to the inactive state before the UE120is scheduled to transition to the inactive state in connection with an occurrence of a CDRX off duration, thereby reducing power consumption without negatively impacting latency relative to a fixed CDRX cycle (where the scheduled CDRX cycle timing matches the actual CDRX cycle timing). For example, in some use cases, power consumption may be 20% reduced for 30 FPS XR and 13% for 48 FPS XR without a negative impact to packet latency.

As indicated above,FIG.6is provided as an example. Other examples may differ from what is described with respect toFIG.6.

As used herein, “satisfying a threshold” may, depending on the context, refer to a value being greater than the threshold, greater than or equal to the threshold, less than the threshold, less than or equal to the threshold, equal to the threshold, not equal to the threshold, or the like.

Even though particular combinations of features are recited in the claims and/or disclosed in the specification, these combinations are not intended to limit the disclosure of various aspects. Many of these features may be combined in ways not specifically recited in the claims and/or disclosed in the specification. The disclosure of various aspects includes each dependent claim in combination with every other claim in the claim set. As used herein, a phrase referring to “at least one of” a list of items refers to any combination of those items, including single members. As an example, “at least one of: a, b, or c” is intended to cover a, b, c, a+b, a+c, b+c, and a+b+c, as well as any combination with multiples of the same element (e.g., a+a, a+a+a, a+a+b, a+a+c, a+b+b, a+c+c, b+b, b+b+b, b+b+c, c+c, and c+c+c, or any other ordering of a, b, and c).

No element, act, or instruction used herein should be construed as critical or essential unless explicitly described as such. Also, as used herein, the articles “a” and “an” are intended to include one or more items and may be used interchangeably with “one or more.” Further, as used herein, the article “the” is intended to include one or more items referenced in connection with the article “the” and may be used interchangeably with “the one or more.” Furthermore, as used herein, the terms “set” and “group” are intended to include one or more items and may be used interchangeably with “one or more.” Where only one item is intended, the phrase “only one” or similar language is used. Also, as used herein, the terms “has,” “have,” “having,” or the like are intended to be open-ended terms that do not limit an element that they modify (e.g., an element “having” A may also have B). Further, the phrase “based on” is intended to mean “based, at least in part, on” unless explicitly stated otherwise. Also, as used herein, the term “or” is intended to be inclusive when used in a series and may be used interchangeably with “and/or,” unless explicitly stated otherwise (e.g., if used in combination with “either” or “only one of”).
