Description

MODIFYING A QUALITY OF SERVICE FLOW PACKET DELAY BUDGET

FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for modifying a quality of service flow packet delay budget.

BACKGROUND

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, and/or the like) . Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, single-carrier frequency-division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE) . LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP) .

A wireless network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs) . A user equipment (UE) may communicate with a base station (BS) via the downlink and uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, a gNB, an access point (AP) , a radio head, a transmit receive point (TRP) , a New Radio (NR) BS, a 5G Node B, and/or the like.

The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment to communicate on a municipal, national, regional, and even global level. New Radio (NR) , which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the Third Generation Partnership Project (3GPP) . NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL) , using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM) ) on the uplink (UL) , as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

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. Based on the teachings herein, 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, and/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.

It should be noted that while aspects may be described herein using terminology commonly associated with a 5G or 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. 1 is a diagram illustrating an example of a wireless network 100, in accordance with various aspects of the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network, an LTE network, and/or the like. The wireless network 100 may include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UEs) and may also be referred to as an NR BS, a Node B, a gNB, a 5G node B (NB) , an access point, a transmit receive point (TRP) , and/or the like. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and/or a BS subsystem serving this coverage area, depending on the context in which the term is used.

A BS may 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 UEs with service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs with service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs having association with the femto cell (e.g., UEs in a closed subscriber group (CSG) ) . A BS for a macro cell may be referred to as a macro BS. A BS for a pico cell may be referred to as a pico BS. A BS for a femto cell may be referred to as a femto BS or a home BS. In the example shown in Fig. 1, a BS 110a may be a macro BS for a macro cell 102a, a BS 110b may be a pico BS for a pico cell 102b, and a BS 110c may be a femto BS for a femto cell 102c. A BS may support one or multiple (e.g., three) cells. The terms “eNB” , “base station” , “NR BS” , “gNB” , “TRP” , “AP” , “node B” , “5G NB” , and “cell” may be used interchangeably herein.

In some aspects, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile BS. In some aspects, the BSs may be interconnected to one another and/or to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces such as a direct physical connection, a virtual network, and/or the like using any suitable transport network.

Wireless network 100 may also include relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., a BS or a UE) and send a transmission of the data to a downstream station (e.g., a UE or a BS) . A relay station may also be a UE that can relay transmissions for other UEs. In the example shown in Fig. 1, a relay BS 110d may communicate with macro BS 110a and a UE 120d in order to facilitate communication between BS 110a and UE 120d. A relay BS may also be referred to as a relay station, a relay base station, a relay, and/or the like.

Wireless network 100 may be a heterogeneous network that includes BSs of different types, e.g., macro BSs, pico BSs, femto BSs, relay BSs, and/or the like. These different types of BSs may have different transmit power levels, different coverage areas, and different impacts on interference in wireless network 100. For example, macro BSs may have a high transmit power level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relay BSs may have lower transmit power levels (e.g., 0.1 to 2 watts) .

A network controller 130 may couple to a set of BSs and may provide coordination and control for these BSs. Network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with one another, e.g., directly or indirectly via a wireless or wireline backhaul.

UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, and/or the like. A UE may 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 or equipment, biometric sensors/devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart ring, smart bracelet) ) , an entertainment device (e.g., a music or video device, or a satellite radio) , a vehicular component or sensor, smart meters/sensors, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, and/or the like, that may communicate with a base station, another device (e.g., remote device) , or some other entity. A wireless node may provide, for example, connectivity for or to a network (e.g., a wide area network such as Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered Internet-of-Things (IoT) devices, and/or may be implemented as NB-IoT (narrowband internet of things) devices. Some UEs may be considered a Customer Premises Equipment (CPE) . UE 120 may be included inside a housing that houses components of UE 120, such as processor components, memory components, and/or the like. In some aspects, 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, electrically coupled, and/or the like.

In general, any number of wireless networks may be deployed in a given geographic area. Each wireless network may support a particular RAT and may operate on one or more frequencies. A RAT may also be referred to as a radio technology, an air interface, and/or the like. A frequency may also be referred to as a carrier, a frequency channel, and/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 aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using a base station 110 as an intermediary to communicate with one another) . For example, the UEs 120 may 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, and/or the like) , a mesh network, and/or the like. In this case, the UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station 110.

Devices of wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided based on frequency or wavelength into various classes, bands, channels, and/or the like. For example, devices of wireless network 100 may communicate using an operating band having a first frequency range (FR1) , which may span from 410 MHz to 7.125 GHz, and/or may communicate using an operating band having a second frequency range (FR2) , which may span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a “sub-6 GHz” band. Similarly, FR2 is often referred to as a “millimeter wave” band 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. Thus, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies less than 6 GHz, frequencies within FR1, and/or mid-band frequencies (e.g., greater than 7.125 GHz) . Similarly, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies within the EHF band, frequencies within FR2, and/or mid-band frequencies (e.g., less than 24.25 GHz) . It is contemplated that the frequencies included in FR1 and FR2 may be modified, and techniques described herein are applicable to those modified frequency ranges.

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

Fig. 2 is a diagram illustrating an example 200 of a base station 110 in communication with a UE 120 in a wireless network 100, in accordance with various aspects of the present disclosure. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T ≥ 1 and R ≥ 1.

At base station 110, a transmit processor 220 may receive data from a data source 212 for one or more UEs, select one or more modulation and coding schemes (MCS) for each UE based at least in part on channel quality indicators (CQIs) received from the UE, process (e.g., encode and modulate) the data for each UE based at least in part on the MCS (s) selected for the UE, and provide data symbols for all UEs. Transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI) and/or the like) and control information (e.g., CQI requests, grants, upper layer signaling, and/or the like) and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., a cell-specific reference signal (CRS) , a demodulation reference signal (DMRS) , and/or the like) and synchronization signals (e.g., the primary synchronization signal (PSS) and secondary synchronization signal (SSS) ) . A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may 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 T output symbol streams to T modulators (MODs) 232a through 232t. Each modulator 232 may process a respective output symbol stream (e.g., for OFDM and/or the like) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and upconvert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

At UE 120, antennas 252a through 252r may receive the downlink signals from base station 110 and/or other base stations and may provide received signals to demodulators (DEMODs) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) a received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM and/or the like) to obtain received symbols. A MIMO detector 256 may obtain received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols if applicable, and provide detected symbols. A receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to a data sink 260, and provide decoded control information and system information to a controller/processor 280. The term “controller/processor” may refer to one or more controllers, one or more processors, or a combination thereof. A channel processor may determine reference signal received power (RSRP) , received signal strength indicator (RSSI) , reference signal received quality (RSRQ) , channel quality indicator (CQI) , and/or the like. In some aspects, one or more components of UE 120 may be included in a housing 284.

Network controller 130 may include communication unit 294, controller/processor 290, and memory 292. Network controller 130 may include, for example, one or more devices in a core network. Network controller 130 may communicate with base station 110 via communication unit 294.

On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RSSI, RSRQ, CQI, and/or the like) from controller/processor 280. Transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, and/or the like) , and transmitted to base station 110. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna (s) 252, modulators and/or demodulators 254, MIMO detector 256, receive processor 258, transmit processor 264, and/or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller/processor 280) and memory 282 to perform aspects of any of the methods described herein, for example, as described with reference to Figs. 4-6.

At base station 110, the uplink signals from UE 120 and other UEs may be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller/processor 240. Base station 110 may include communication unit 244 and communicate to network controller 130 via communication unit 244. Base station 110 may include a scheduler 246 to schedule UEs 120 for downlink and/or uplink communications. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna (s) 234, modulators and/or demodulators 232, MIMO detector 236, receive processor 238, transmit processor 220, and/or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller/processor 240) and memory 242 to perform aspects of any of the methods described herein, for example, as described with reference to Figs. 4-6.

Controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component (s) of Fig. 2 may perform one or more techniques associated with modifying a QoS flow packet delay budget, as described in more detail elsewhere herein. For example, controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component (s) of Fig. 2 may perform or direct operations of, for example, process 500 of Fig. 5, process 600 of Fig. 6, and/or other processes as described herein.

Memories

242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and/or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code, program code, and/or the like) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, interpreting, and/or the like) by one or more processors of the base station 110 and/or the UE 120, may cause the one or more processors, the UE 120, and/or the base station 110 to perform or direct operations of, for example, process 500 of Fig. 5, process 600 of Fig. 6, and/or other processes as described herein. In some aspects, executing instructions may include running the instructions, converting the instructions, compiling the instructions, interpreting the instructions, and/or the like.

In some aspects, a mobile station (e.g., a UE 120) may include means for receiving an indication of a packet delay budget value associated with a QoS flow, means for transmitting a request to modify the packet delay budget value to a different packet delay budget value, and/or the like. In some aspects, such means may include one or more components of UE 120 described in connection with Fig. 2, such as controller/processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and/or the like.

In some aspects, base station 110 may include means for transmitting, to a mobile station, an indication of a packet delay budget value associated with a QoS flow, means for receiving, from the mobile station, a request to modify the packet delay budget value to a different packet delay budget value, and/or the like. In some aspects, such means may include one or more components of base station 110 described in connection with Fig. 2, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller/processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like.

While blocks in Fig. 2 are 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 processor 264, the receive processor 258, and/or the TX MIMO processor 266 may be performed by or under the control of controller/processor 280.

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

Fig. 3 illustrates an example 300 of a 5G network architecture, in accordance with various aspects of the present disclosure. The 5G network architecture may include a next generation radio access network (NG-RAN) , which may include one or more base stations, such as base station 110, that communicate with a UE, such as UE 120 or a mobile station, over a Uu interface. The Uu interface is a radio interface between the UE and the NG-RAN. The 5G network architecture may include a 5G core network (5GC) that provides communications between the NG-RAN and the outside world, including devices that may act as servers for the 5GC, such as mobile network operator servers, cloud servers, third-party servers, servers of companies that may provide data and services to the UE through applications on the UE, and/or the like.

The 5GC may include a unified data management (UDM) entity that makes relevant data available to an access and mobility management function (AMF) entity and a session management function (SMF) entity. The AMF entity manages UE network registration, manages mobility, maintains a non-access stratum (NAS) signaling connection with the UE, and manages a registration procedure of the UE with a network. The SMF entity manages sessions and allocates internet protocol (IP) addresses to the UE. The 5GC includes a user plane function (UPF) entity that manages user traffic to and from the UE through the NG-RAN and enforces a quality of service (QoS) . The 5GC includes a policy and control function (PCF) entity that implements charging rules, implements flow control rules, manages traffic priority, and manages a QoS for user subscription services. The 5GC may include a unified data repository (UDR) entity that stores structured data for exposure to network functions and a network exposure function (NEF) entity that securely exposes services and capabilities provided by 3GPP network functions. The 5GC also includes an application function (AF) entity that supports application functionality, influences traffic routing, and interacts with the PCF entity.

While 4G Long Term Evolution (LTE) uses evolved packet system (EPS) bearers, each assigned an EPS bearer identifier (ID) , 5G uses QoS flows, each identified by a QoS flow ID (QFI) . The QoS flow is where policy and charging are enforced. All traffic within the same QoS flow may receive the same treatment. In the 5GC, there is a single user plane network function –the UPF –for transport of data between a base station (e.g., gNB) and the 5GC. Each QoS flow on an N3 interface may be mapped to a single general packet radio service (GPRS) tunneling protocol (GTP) tunnel for the user plane (GTP-U) . The gNB may map individual QoS flows to one more dedicated radio bearers (DRBs) . A protocol data unit (PDU) session may contain multiple QoS flows and several DRBs, but only a single N3 GTP-U tunnel. A DRB may transport one or more QoS flows. These entities permit user data traffic or other types of information to be transmitted on a user plane.

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

In some cases, a QoS flow may include one or more QoS parameters, such as a priority level, a packet delay budget, a permitted packet error rate, and/or the like. The one or more QoS parameters may be based at least in part on a traffic type associated with an application. For example, the one or more QoS parameters may be associated with particular values if the application traffic is voice traffic, may be associated with other particular values if the application traffic is video traffic, and/or the like.

The packet delay budget may define an upper bound for an amount of time that a packet may be delayed between a UE and a UPF of a 5GC. The QoS parameters, including the packet delay budget, may be determined by the 5GC and communicated to an NG-RAN (e.g., a base station) to coordinate the scheduling of radio resources by the NG-RAN for traffic associated with a particular QoS flow. In some cases, the 5GC may require a relatively low packet delay value (e.g., compared to a value of the packet delay budget for a QoS flow) . The 5GC may determine (e.g., estimate) a value for the packet delay budget to enable the NG-RAN to schedule radio resources for traffic associated with the QoS flow.

In some cases, traffic for a UE may be associated with strict latency requirements. For example, the UE, or an application of the UE, may be associated with an ultra-reliable low latency communication (URLLC) service. As a result, traffic associated with the URLLC service is subject to strict latency requirements. However, the 5GC and/or the NG-RAN may be unaware of, or may have a limited knowledge of, the latency requirements of the UE (or the application of the UE) . Therefore, the packet delay budget of the QoS flow for traffic associated with the UE having strict latency requirements may be determined by the 5GC without a complete understanding of the strict latency requirements. As a result, packets addressed for the UE associated with the QoS flow (e.g., for traffic that is associated with the strict latency requirements, such as URLLC traffic) may be delayed by the 5GC and/or the NG-RAN, in accordance with the packet delay budget, such that the packets do not satisfy the latency requirement of the UE. Those packets may be counted as lost by the UE, thereby degrading network performance and wasting network resources associated with transmitting (and/or re-transmitting) the lost packets.

Some techniques and apparatuses described herein enable a UE to modify a QoS flow packet delay budget. For example, the UE may be enabled to participate in a negotiation procedure associated with the QoS flow packet delay budget value. The 5GC and/or the NG-RAN may communicate one or more QoS parameters (including the packet delay budget) for a QoS flow to the UE. The UE may determine that the value of the packet delay budget for the QoS flow should be changed (e.g., based at least in part on a latency requirement of the UE) . The UE may determine a different value for the packet delay budget (e.g., based at least in part on the latency requirement of the UE) . The UE may transmit a request, to the 5GC and/or the NG-RAN, to modify the value of the packet delay budget to the different value. If the 5GC and/or the NG-RAN determine to accept the request to modify the value of the packet delay budget to the different value, the 5GC and/or the NG-RAN will schedule radio resources for traffic associated with the QoS flow using the different value of the packet delay budget. This enables the UE to participate in the determination of the packet delay budget and have control of a QoS flow latency. As a result, packets addressed for the UE associated with the QoS flow will not be delayed (e.g., based at least in part on the packet delay budget) longer than the latency requirement for the UE. This improves network performance and conserves network resources that would have otherwise been used transmitting (and/or re-transmitting) packets that would be counted as lost by the UE based at least in part on the latency requirements of the UE.

Fig. 4 is a diagram illustrating an example 400 associated with modifying a QoS flow packet delay budget, in accordance with various aspects of the present disclosure. As shown in Fig. 4, example 400 includes communication between a base station 110 and a UE 120. In some aspects, the base station 110 and the UE 120 may be included in a wireless network, such as wireless network 100. The base station 110 and the UE 120 may communicate on a wireless access link, which may include an uplink and a downlink. In some aspects, the base station 110 may be associated with an NG-RAN. In some aspects, the base station 110 may be associated with a 5GC (e.g., the base station 110 may be a core network device) . For example, the base station 110 may be associated with an AMF entity of the 5GC. The UE 120 may be referred to herein as a mobile station.

As show by reference number 405, the base station 110 may transmit, and the UE 120 may receive, an indication of a packet delay budget value for a QoS flow. For the example, the base station 110 (e.g., the 5GC and/or the NG-RAN) may transmit an indication of one or more QoS parameters (including the packet delay budget) for the QoS flow to the UE 120. The base station 110 may identify the QoS flow in the indication using a QFI. In some aspects, the base station 110 may transmit the indication of the packet delay budget value for the QoS flow using an N1 interface (e.g., the 5GC may transmit the indication directly to the UE 120) . In some aspects, the base station 110 may transmit the indication of the packet delay budget value for the QoS flow using a Uu interface (e.g., the NG-RAN may transmit the indication to the UE 120 after receiving the QoS flow parameters from the 5GC) .

In some aspects, the QoS flow may be a guaranteed bit rate (GBR) QoS flow associated with delay-critical traffic (e.g., URLLC traffic) . The base station 110 may transmit the indication of the packet delay budget value for the QoS flow after determining the packet delay budget value for the QoS flow (e.g., after creating the QoS flow in a PDU session) .

As shown by reference number 410, the UE 120 may determine that the packet delay budget value does not satisfy a latency requirement associated with the UE 120 (or a latency requirement associated with an application of the UE 120) . For example, the UE 120 may be a URLLC UE 120, or an application of the UE 120 may be associated with a URLLC service. The UE 120 may determine that if a packet associated with the QoS flow is delayed in accordance with the packet delay budget, that the delay may cause the packet to not satisfy the latency requirement (e.g., and be counted as lost by the UE 120) . For example, the base station 110 may indicate that the packet delay budget value is 200 milliseconds. The UE 120 may determine that if a packet is delayed by the base station 110 (e.g., by the 5GC and/or by the NG-RAN) for 200 milliseconds, then the packet will not satisfy the latency requirements of the UE 120. As a result, the UE 120 may determine that the packet delay budget value for the QoS flow should be changed.

As shown by reference number 415, the UE 120 may determine a different packet delay budget value for the QoS flow based at least in part on the latency requirement associated with the UE 120. For example, the UE 120 may determine a permissible amount of time that a packet can be delayed (e.g., by the 5GC and/or the NG-RAN) and still satisfy the latency requirements of the UE 120. In some aspects, the UE 120 may determine a maximum amount of time that a packet can be delayed (e.g., by the 5GC and/or the NG-RAN) and still satisfy the latency requirements of the UE 120. For example, the base station 110 may indicate the packet delay budget value is 200 milliseconds, as described in the example above. The UE 120 may determine that the packet delay budget value should be 50 milliseconds, to satisfy the latency requirements of the UE 120 (or the latency requirements of an application of the UE 120) .

As shown by reference number 420, the UE 120 may transmit, and the base station 110 may receive, a request to modify the packet delay budget value of the QoS flow to the different packet delay budget value. In some aspects, the UE 120 may transmit the request to modify the packet delay budget value of the QoS flow to the different packet delay budget value using an N1 interface (e.g., the UE 120 may transmit the request directly to the 5GC) . In some aspects, the UE 120 may transmit the request to modify the packet delay budget value of the QoS flow to the different packet delay budget value using a Uu interface (e.g., the UE 120 may transmit the request to the NG-RAN) . In that case, the base station 110 may forward (e.g., transmit) the request to modify the packet delay budget value of the QoS flow to the different packet delay budget to the 5GC (e.g., using an N2 interface and/or the like) .

As shown by reference number 425, the base station 110 may determine whether to accept the request to modify the packet delay budget value to the different packet delay budget value for the QoS flow based at least in part on scheduling requirements of an access network (e.g., the NG-RAN) . In some aspects, the 5GC may determine whether to accept the request to modify the packet delay budget value to the different packet delay budget value for the QoS flow based at least in part on scheduling requirements of the NG-RAN. For example, the NG-RAN may not be able to support scheduling radio resources using the different value for the packet delay budget for the QoS flow.

If the base station 110 determines that the request to modify the packet delay budget value to the different packet delay budget value for the QoS flow should be accepted, the base station 110 may modify the packet delay budget value in the QoS parameters associated with the QoS flow. For example, the 5GC may modify or update the packet delay budget value to the different value in a QoS profile associated with the QoS flow. The 5GC may transmit, to the NG-RAN, an indication of the modified QoS profile that indicates the different value for the packet delay budget.

In some aspects, the base station 110 may transmit, and the UE 120 may receive, an indication of whether the request to modify the packet delay budget value to the different packet delay budget value for the QoS flow is accepted. For example, if the request to modify the packet delay budget value to the different packet delay budget value for the QoS flow is accepted, the base station 110 may transmit, to the UE 120, an indication of the modified QoS profile that indicates the different value for the packet delay budget. If the request to modify the packet delay budget value to the different packet delay budget value for the QoS flow is rejected, the base station 110 may not transmit any indications to the UE 120 or may transmit an indication to the UE 120 that the request is rejected.

As shown by reference number 430, the base station 110 may transmit, and the UE 120 may receive, scheduling information for traffic associated with the QoS flow. For example, the NG-RAN may schedule radio resources for traffic associated with the QoS flow. If the request to modify the packet delay budget value to the different packet delay budget value for the QoS flow is accepted, the base station 110 may schedule the radio resources using the different packet delay budget value (e.g., the scheduling information transmitted to the UE 120 is based at least in part on the different packet delay budget value) . For example, the base station 110 (e.g., the NG-RAN) may determine the scheduling information for radio resources associated with the QoS flow using the different packet delay budget value. If the request to modify the packet delay budget value to the different packet delay budget value for the QoS flow is rejected, the base station 110 may schedule the radio resources using the original packet delay budget value (e.g., that was indicated by the base station 110 as described above with respect to reference number 405) .

In this way, the UE 120 may participate in the determination of the packet delay budget value and have control of the QoS flow latency. As a result, packets addressed for the UE 120 associated with the QoS flow will not be delayed (e.g., based at least in part on the packet delay budget value) longer than the latency requirement for the UE 120. This improves network performance and conserves network resources that would have otherwise been used transmitting (and/or re-transmitting) packets that would be counted as lost by the UE 120 based at least in part on the latency requirements of the UE 120.

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

For example, the base station (e.g., using transmit processor 220, TX MIMO processor 230, modulator 232, antenna 234, controller/processor 240, memory 242, and/or scheduler 246) may transmit, to a mobile station, an indication of a packet delay budget value associated with a QoS flow, as described above.
