CROSS-REFERENCE TO RELATED APPLICATION 
     This patent application claims priority to U.S. Provisional Patent Application No. 63/282,592, filed on Nov. 23, 2021, entitled “MODIFYING MODEM TIMERS BASED ON JITTER TIMING ASSOCIATED WITH AN APPLICATION,” and assigned to the assignee hereof. The disclosure of the prior application is considered part of and is incorporated by reference into this patent application. 
    
    
     FIELD OF THE DISCLOSURE 
     Aspects of the present disclosure generally relate to wireless communication and specifically, to techniques and apparatuses for modifying modem timers based on jitter timing associated with an application. 
     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 (for example, bandwidth or transmit power). 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). 
     The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment (UEs) to communicate on a municipal, national, regional, or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 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, using CP-OFDM or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, 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. 
     In a communication system, the end-to-end delay of a data packet may be defined as the time from its generation at the source to when the data packet reaches its destination. In a packet-switched communication system, the delay for data packets to travel from source to destination may vary depending upon various operating conditions, including, but not limited to, channel conditions and network loading. Channel conditions refer to the quality of the wireless link (for example, signal strength, speed of a UE, or physical obstructions). The end-to-end delay includes the delays introduced in the network and the various elements through which the data packet passes. Many factors contribute to end-to-end delay. Variance in the end-to-end delay is referred to as jitter. Jitter may cause data packets to be received after the data packets are no longer useful. For example, in a low latency application, such as a voice application, if a data packet is received too late, it may be dropped by the receiver, resulting in degradation of the quality of communication. 
     Different applications like games, extended reality applications, augmented reality applications, or virtual reality applications, among other examples, can have different jitter buffer requirements and processing requirements based on the software or hardware interconnect entities involved or processing in external hardware or software blocks with different schedulers. 
     Jitter management and modem timers such as a reassembly timer and a reordering timer are often independently configured by the network, which may lead to delayed real-time transport protocol packet delivery to an internet protocol (IP) multimedia subsystem (IMS) application. Though quality of service mechanisms are outlined in some wireless communication standards to facilitate coordinated configuration, radio level radio link control (RLC) protocol and radio packet data convergence protocol configuration (at a network node) is configured to achieve average latency requirements rather than peak latency requirements that can be associated with the IMS application. Additionally, the physical layer radio conditions and location of the UE can cause challenges with ensuring successful transmission and reception at the physical layer level. If modem timers are configured such that data packet delivery from the modem to the IMS application causes enough delay to overshoot the jitter buffer timing, underflow can result, causing a poor user experience, even when the modem attempts to successfully recover the data packets with proactive retransmissions or duplications at medium access control levels and RLC levels. 
     SUMMARY 
     Some aspects described herein relate to a user equipment (UE) for wireless communication. The UE may include at least one processor and at least one memory, communicatively coupled with the at least one processor, that stores processor-readable code. The processor-readable code, when executed by the at least one processor, may be configured to cause the UE to generate at least one modified timing value corresponding to at least one modem timer by modifying at least one configured timing value corresponding to the at least one modem timer based at least in part on a jitter timing value associated with an application that is instantiated on the UE.

The method may include receiving at least one data packet based at least in part on the at least one modified timing value. 
     Some aspects described herein relate to a non-transitory computer-readable medium that stores a set of instructions for wireless communication by a UE. The set of instructions, when executed by one or more processors of the UE, may cause the UE to generate at least one modified timing value corresponding to at least one modem timer by modifying at least one configured timing value corresponding to the at least one modem timer based at least in part on a jitter timing value associated with an application that is instantiated on the UE. The set of instructions, when executed by one or more processors of the UE, may cause the UE to receive at least one data packet based at least in part on the at least one modified timing value. 
     Some aspects described herein relate to an apparatus for wireless communication. The apparatus may include means for generating at least one modified timing value corresponding to at least one modem timer by modifying at least one configured timing value corresponding to the at least one modem timer based at least in part on a jitter timing value associated with an application that is instantiated on the apparatus.

     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 are not to 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 may 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 quantity 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. 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, or algorithms (collectively referred to as “elements”). These elements may be implemented using hardware, software, or a combination of hardware and software. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system. 
     Various aspects relate generally to delivering data packets with a timing to achieve a balance between delivering data packets in time and delivering data packets with minimal loss. Some aspects more specifically relate to modifying configured modem timers based at least in part on jitter timing values associated with applications. In some aspects, a user equipment (UE) may generate at least one modified timing value corresponding to at least one modem timer by modifying at least one configured timing value corresponding to the at least one modem timer based at least in part on a jitter timing value associated with an application that is instantiated on the UE. In some aspects, the UE may receive at least one data packet based at least in part on the at least one modified timing value. 
     Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, the described techniques can be used to reduce underflow of jitter buffers, thereby resulting in fewer lost data packets and, as a result, a positive impact on user experience. 
       FIG.  1    is a diagram illustrating an example of a wireless network in accordance with the present disclosure. The wireless network  100  may be or may include elements of a 5G (for example, NR) network or a 4G (for example, Long Term Evolution (LTE)) network, among other examples. The wireless network  100  may include one or more network nodes  110  (shown as a network node (NN)  110   a , a network node  110   b , a network node  110   c , and a network node  110   d ), a user equipment (UE)  120  or multiple UEs  120  (shown as a UE  120   a , a UE  120   b , a UE  120   c , a UE  120   d , and a UE  120   e ), or other network entities. A network node  110  is an entity that communicates with UEs  120 . A network node  110  may include, for example, a base station, an NR network node, an LTE network node, a Node B, an eNB (for example, in 4G), a gNB (for example, in 5G), an access point, or a transmission reception point (TRP), a distributed unit (DU), a radio unit (RU), a central unit (CU), a mobility element of a network, a core network node, a network element, a network equipment, and/or a radio access network (RAN) node. 
     Each network node  110  may 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 network node  110  or a network node subsystem serving this coverage area, depending on the context in which the term is used. 
     A network node  110  may provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographic area (for example, several kilometers in radius) and may allow unrestricted access by UEs  120  with service subscriptions. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs  120  with service subscription. A femto cell may cover a relatively small geographic area (for example, a home) and may allow restricted access by UEs  120  having association with the femto cell (for example, UEs  120  in a closed subscriber group (CSG)). A network node  110  for a macro cell may be referred to as a macro network node. A network node  110  for a pico cell may be referred to as a pico network node. A network node  110  for a femto cell may be referred to as a femto network node or an in-home network node. 
     The wireless network  100  may be a heterogeneous network that includes network nodes  110  of different types, such as macro network nodes, pico network nodes, femto network nodes, or relay network nodes. These different types of network nodes  110  may have different transmit power levels, different coverage areas, or different impacts on interference in the wireless network  100 . For example, macro network nodes may have a high transmit power level (for example, 5 to 40 watts) whereas pico network nodes, femto network nodes, and relay network nodes may have lower transmit power levels (for example, 0.1 to 2 watts). In the example shown in  FIG.  1   , the network node  110   a  may be a macro network node for a macro cell  102   a , the network node  110   b  may be a pico network node for a pico cell  102   b , and the network node  110   c  may be a femto network node for a femto cell  102   c . A network node may support one or multiple (for example, three) cells. 
     In some aspects, the terms “base station” or “network node” may refer to an aggregated base station, a disaggregated base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, “base station” or “network node” may refer to a CU, a DU, an RU, a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC), and/or a Non-Real Time (Non-RT) RIC. In some aspects, the terms “base station” or “network node” may refer to one device configured to perform one or more functions, such as those described herein in connection with the network node  110 . In some aspects, the terms “base station” or “network node” may refer to a plurality of devices configured to perform the one or more functions. For example, in some distributed systems, each of a quantity of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to duplicate performance of at least a portion of the function, and the terms “base station” or “network node” may refer to any one or more of those different devices. In some aspects, the terms “base station” or “network node” may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the terms “base station” or “network node” may refer to one of the base station functions and not another. In this way, a single device may include more than one base station. 
     A network controller  130  may couple to or communicate with a set of network nodes  110  and may provide coordination and control for these network nodes  110 . The network controller  130  may communicate with the network nodes  110  via a backhaul communication link. The network nodes  110  may communicate with one another directly or indirectly via a wireless or wireline backhaul communication link. In some aspects, the network controller  130  may be a CU or a core network device, or the network controller  130  may include a CU or a core network device. 
     In some examples, a cell may not necessarily be stationary, and the geographic area of the cell may move in accordance with the location of a network node  110  that is mobile (for example, a mobile network node). In some examples, the network nodes  110  may be interconnected to one another or to one or more other network nodes  110  or network nodes (not shown) in the wireless network  100  through various types of backhaul interfaces, such as a direct physical connection or a virtual network, using any suitable transport network. 
     The wireless network  100  may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (for example, a network node  110  or a UE  120 ) and send a transmission of the data to a downstream station (for example, a UE  120  or a network node  110 ). A relay station may be a UE  120  that can relay transmissions for other UEs  120 . In the example shown in  FIG.  1   , the network node  110   d  (for example, a relay network node) may communicate with the network node  110   a  (for example, a macro network node) and the UE  120   d  in order to facilitate communication between the network node  110   a  and the UE  120   d . A network node  110  that relays communications may be referred to as a relay station, a relay network node, or a relay. 
     The UEs  120  may be dispersed throughout the wireless network  100 , and each UE  120  may be stationary or mobile. A UE  120  may include, for example, an access terminal, a terminal, a mobile station, or a subscriber unit. A UE  120  may be a cellular phone (for example, 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 (for example, a smart watch, smart clothing, smart glasses, a smart wristband, smart jewelry (for example, a smart ring or a smart bracelet)), an entertainment device (for example, a music device, a video device, or a satellite radio), a vehicular component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, a UE function of a network node, or any other suitable device that is configured to communicate via a wireless medium. 
     Some UEs  120  may be considered machine-type communication (MTC) or evolved or enhanced machine-type communication (eMTC) UEs. An MTC UE or an eMTC UE may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, or a location tag, that may communicate with a network node, another device (for example, a remote device), or some other entity. Some UEs  120  may be considered Internet-of-Things (IoT) devices, or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs  120  may be considered a Customer Premises Equipment. A UE  120  may be included inside a housing that houses components of the UE  120 , such as processor components or memory components. In some examples, the processor components and the memory components may be coupled together. For example, the processor components (for example, one or more processors) and the memory components (for example, a memory) may be operatively coupled, communicatively coupled, electronically coupled, or electrically coupled. 
     In general, any quantity of wireless networks  100  may be deployed in a given geographic area. Each wireless network  100  may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology or an air interface. A frequency may be referred to as a carrier or a frequency channel. 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 UEs  120  (for example, shown as UE  120   a  and UE  120   e ) may communicate directly using one or more sidelink channels (for example, without using a network node  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 (for example, which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), or a mesh network. In such examples, a UE  120  may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by the network node  110 . 
     Devices of the wireless network  100  may communicate using the electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, or channels. For example, devices of the wireless network  100  may 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). 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 in connection with 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 or FR2 characteristics, and thus may effectively extend features of FR1 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, the term “sub-6 GHz,” 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, the term “millimeter wave,” if used herein, may broadly represent frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (for example, FR1, FR2, FR3, FR4, FR4-a, FR4-1, or FR5) may be modified, and techniques described herein are applicable to those modified frequency ranges. 
     In some aspects, the UE  120  may include a communication manager  140 . As described in more detail elsewhere herein, the communication manager  140  may generate at least one modified timing value corresponding to at least one modem timer by modifying at least one configured timing value corresponding to the at least one modem timer based at least in part on a jitter timing value associated with an application that is instantiated on the UE; and receive at least one data packet based at least in part on the at least one modified timing value. Additionally or alternatively, the communication manager  140  may perform one or more other operations described herein. 
       FIG.  2    is a diagram illustrating an example network node in communication with a UE in a wireless network in accordance with the present disclosure. The network node may correspond to the network node  110  of  FIG.  1   . Similarly, the UE may correspond to the UE  120  of  FIG.  1   . The network node  110  may be equipped with a set of antennas  234   a  through  234   t , such as T antennas (T≥1). The UE  120  may be equipped with a set of antennas  252   a  through  252   r , such as R antennas (R≥1). The network node  110  depicted in  FIG.  2    includes one or more radio frequency components, such as antennas  234  and a modem  232 . In some examples, a network node  110  may include an interface, a communication component, or another component that facilitates communication with the UE  120  or another network node. Some network nodes  110  may not include radio frequency components that facilitate direct communication with the UE  120 , such as one or more CUs, or one or more DUs. 
     At the network node  110 , a transmit processor  220  may receive data, from a data source  212 , intended for the UE  120  (or a set of UEs  120 ). The transmit processor  220  may select one or more modulation and coding schemes (MCSs) for the UE  120  based at least in part on one or more channel quality indicators (CQIs) received from that UE  120 . The network node  110  may process (for example, encode and modulate) the data for the UE  120  based at least in part on the MCS(s) selected for the UE  120  and may provide data symbols for the UE  120 . The transmit processor  220  may process system information (for example, for semi-static resource partitioning information (SRPI)) and control information (for example, CQI requests, grants, or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor  220  may generate reference symbols for reference signals (for example, a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and synchronization signals (for example, a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor  230  may perform spatial processing (for example, precoding) on the data symbols, the control symbols, the overhead symbols, or the reference symbols, if applicable, and may provide a set of output symbol streams (for example, T output symbol streams) to a corresponding set of modems  232  (for example, T modems), shown as modems  232   a  through  232   t . For example, each output symbol stream may be provided to a modulator component (shown as MOD) of a modem  232 . Each modem  232  may use a respective modulator component to process a respective output symbol stream (for example, for OFDM) to obtain an output sample stream. Each modem  232  may further use a respective modulator component to process (for example, convert to analog, amplify, filter, or upconvert) the output sample stream to obtain a downlink signal. The modems  232   a  through  232   t  may transmit a set of downlink signals (for example, T downlink signals) via a corresponding set of antennas  234  (for example, T antennas), shown as antennas  234   a  through  234   t.    
     At the UE  120 , a set of antennas  252  (shown as antennas  252   a  through  252   r ) may receive the downlink signals from the network node  110  or other network nodes  110  and may provide a set of received signals (for example, R received signals) to a set of modems  254  (for example, R modems), shown as modems  254   a  through  254   r . For example, each received signal may be provided to a demodulator component (shown as DEMOD) of a modem  254 . Each modem  254  may use a respective demodulator component to condition (for example, filter, amplify, downconvert, or digitize) a received signal to obtain input samples. Each modem  254  may use a demodulator component to further process the input samples (for example, for OFDM) to obtain received symbols. A MIMO detector  256  may obtain received symbols from the modems  254 , may perform MIMO detection on the received symbols if applicable, and may provide detected symbols. A receive processor  258  may process (for example, demodulate and decode) the detected symbols, may provide decoded data for the UE  120  to a data sink  260 , and may provide decoded control information and system information to a controller/processor  280 . The term “controller/processor” may refer to one or more controllers and/or one or more processors. 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, or a CQI parameter, among other examples. In some examples, one or more components of the UE  120  may be included in a housing  284 . 
     The network controller  130  may include a communication unit  294 , a controller/processor  290 , and a memory  292 . The network controller  130  may include, for example, one or more devices in a core network. The network controller  130  may communicate with the network node  110  via the communication unit  294 . 
     One or more antennas (for example, antennas  234   a  through  234   t  or antennas  252   a  through  252   r ) may include, or may be included within, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, 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, or one or more antenna elements coupled to one or more transmission or reception components, such as one or more components of  FIG.  2   . 
     On the uplink, at the UE  120 , a transmit processor  264  may receive and process data from a data source  262  and control information (for example, for reports that include RSRP, RSSI, RSRQ, or CQI) from the controller/processor  280 . The transmit processor  264  may generate reference symbols for one or more reference signals. The symbols from the transmit processor  264  may be precoded by a TX MIMO processor  266  if applicable, further processed by the modems  254  (for example, for DFT-s-OFDM or CP-OFDM), and transmitted to the network node  110 . In some examples, the modem  254  of the UE  120  may include a modulator and a demodulator. In some examples, the UE  120  includes a transceiver. The transceiver may include any combination of the antenna(s)  252 , the modem(s)  254 , the MIMO detector  256 , the receive processor  258 , the transmit processor  264 , or the TX MIMO processor  266 . The transceiver may be used by a processor (for example, the controller/processor  280 ) and the memory  282  to perform aspects of any of the methods described herein. 
     At the network node  110 , the uplink signals from UE  120  or other UEs may be received by the antennas  234 , processed by the modem  232  (for example, a demodulator component, shown as DEMOD, of the modem  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 the UE  120 . The receive processor  238  may provide the decoded data to a data sink  239  and provide the decoded control information to the controller/processor  240 . The network node  110  may include a communication unit  244  and may communicate with the network controller  130  via the communication unit  244 . The network node  110  may include a scheduler  246  to schedule one or more UEs  120  for downlink or uplink communications. In some examples, the modem  232  of the network node  110  may include a modulator and a demodulator. In some examples, the network node  110  includes a transceiver. The transceiver may include any combination of the antenna(s)  234 , the modem(s)  232 , the MIMO detector  236 , the receive processor  238 , the transmit processor  220 , or the TX MIMO processor  230 . The transceiver may be used by a processor (for example, the controller/processor  240 ) and the memory  242  to perform aspects of any of the methods described herein. 
     The controller/processor  240  of the network node  110 , the controller/processor  280  of the UE  120 , or any other component(s) of  FIG.  2    may perform one or more techniques associated with modifying modem timers based on jitter timing associated with an application, as described in more detail elsewhere herein. For example, the controller/processor  240  of the network node  110 , the controller/processor  280  of the UE  120 , or any other component(s) of  FIG.  2    may perform or direct operations of, for example, process  600  of  FIG.  6   . The memory  242  and the memory  282  may store data and program codes for the network node  110  and the UE  120 , respectively. In some examples, the memory  242  or the memory  282  may include a non-transitory computer-readable medium storing one or more instructions (for example, code or program code) for wireless communication. For example, the one or more instructions, when executed (for example, directly, or after compiling, converting, or interpreting) by one or more processors of the network node  110  or the UE  120 , may cause the one or more processors, the UE  120 , or the network node  110  to perform or direct operations of, for example, process  600  of  FIG.  6   . In some examples, executing instructions may include running the instructions, converting the instructions, compiling the instructions, or interpreting the instructions, among other examples. 
     In some aspects, the UE includes means for generating at least one modified timing value corresponding to at least one modem timer by modifying at least one configured timing value corresponding to the at least one modem timer based at least in part on a jitter timing value associated with an application that is instantiated on the UE; or means for receiving at least one data packet based at least in part on the at least one modified timing value. The means for the UE to perform operations described herein may include, for example, one or more of communication manager  140 , antenna  252 , modem  254 , MIMO detector  256 , receive processor  258 , transmit processor  264 , TX MIMO processor  266 , controller/processor  280 , or memory  282 . 
       FIG.  3    is a diagram illustrating an example of a wireless communication network  300 , in accordance with the present disclosure. As shown, the wireless communication network  300  includes a UE  302  and a network node  304  that communicate with one another. Additionally, the network node  304  can communicate with a core network  306 . 
     The network node  304  can transmit, via an over-the-air (OTA) interface  308 , a data packet to the UE  302  in a downlink transmission, and the UE  302  can transmit a data packet, via the OTA interface  308 , to the network node  304  in an uplink transmission. The UE  302  can receive and transmit data packets using a component such as a modem  310 . The network node  304  can include a central unit (CU)  312  or one or more distributed units (DUs) (for example, one or more TRPs)  314 . The DU  314  can host one or more TRPs and can, for example, be located at edges of the network  300  with radio frequency (RF) functionality. 
     As used herein, the term “data packet” refers to a unit of data for transmission between a transmitting device and a receiving device. For example, “data packet” can refer to a packet of data according to a particular communications protocol, such as an internet protocol (IP) packet or a transmission control protocol (TCP) packet. In some examples, “data packet” can refer to a data unit of a communications protocol stack (for example, a unit of data transferred between one protocol layer and another protocol layer), such as a protocol data unit (PDU) or a service data unit (SDU) of a particular protocol layer. A data packet can be transmitted over a communications medium, including, for example, one or more modulated signals such as OFDM symbols carried by one or more carrier frequencies or subcarrier frequencies of a radio frequency spectrum band. 
     The wireless communication network  300  operates according to a layered protocol stack. The modem  310  can implement one or more portions of the layered protocol stack. In a user plane, communications at the bearer or packet data convergence protocol (PDCP) layer  316  can be IP-based. The PDCP layer  316  may handle various services and functions on the user plane, including sequence numbering, header compression and decompression (if robust header compression is enabled), transfer of user data, reordering and duplicate detection (if in-order delivery to layers above the PDCP layer is required), PDCP protocol data unit (PDU) routing (in case of split bearers), retransmission of PDCP service data units (SDUs), ciphering and deciphering, PDCP SDU discard (for example, in accordance with a timer, as described elsewhere herein), PDCP re-establishment and data recovery for RLC acknowledged mode (AM), and duplication of PDCP PDUs. The PDCP layer may handle similar services and functions on the control plane, including sequence numbering, ciphering, deciphering, integrity protection, transfer of control plane data, duplicate detection, and duplication of PDCP PDUs. 
     A radio link control (RLC) layer  318  can perform data packet segmentation and reassembly to communicate over logical channels. A set  320  of lower level layers can include a medium access control (MAC) layer and a physical layer (which may be referred to as a physical layer or Layer 1, shown as “L1”). The MAC layer can perform priority handling and multiplexing of logical channels into transport channels. The MAC layer can also use error detection techniques, error correction techniques, or both to support retransmissions at the MAC layer to improve link efficiency. At the physical layer, transport channels can be mapped to physical channels. 
     A radio resource control (RRC) layer (not shown) can provide establishment, configuration, and maintenance of an RRC connection between the UE and a network node or a core network. The RRC layer can determine a modem configuration and provide details of the modem configuration to the modem  310 . For example, network node  304  can transmit an RRC message containing the modem configuration. In some cases, a modem configuration can include a timer configuration that configures one or more modem timers. The modem configuration can include any number of additional configuration parameters. 
     On the uplink, the PDCP layer can map radio bearers to RLC channels. The PDCP layer can handle various services and functions on the user plane, including sequence numbering, header compression and decompression (if robust header compression is enabled), transfer of user data, reordering and duplicate detection (if in-order delivery to layers above the PDCP layer is required), PDCP PDU routing (in case of split bearers), retransmission of PDCP SDUs, ciphering and deciphering, PDCP SDU discard (for example, in accordance with a timer, as described elsewhere herein), PDCP re-establishment and data recovery for RLC AM, and duplication of PDCP PDUs. The PDCP layer can handle similar services and functions on the control plane, including sequence numbering, ciphering, deciphering, integrity protection, transfer of control plane data, duplicate detection, and duplication of PDCP PDUs. An SDU is a data packet received by a layer and a PDU is a data packet output of a layer. 
     The PDCP layer can provide data, in the form of PDCP PDUs, to the RLC layer via RLC channels. The RLC layer can handle transfer of upper layer PDUs to the MAC or physical layers, sequence numbering independent of PDCP sequence numbering, error correction via automatic repeat requests (ARQs), segmentation and re-segmentation, reassembly of an SDU, RLC SDU discard, and RLC re-establishment. 
     The RLC layer can provide data, mapped to logical channels, to the MAC layer. The services and functions of the MAC layer include mapping between logical channels and transport channels (used by the physical layer as described below), multiplexing/demultiplexing of MAC SDUs belonging to one or different logical channels into/from transport blocks (TBs) delivered to/from the physical layer on transport channels, scheduling information reporting, error correction through hybrid ARQ (HARD), priority handling between UEs by means of dynamic scheduling, priority handling between logical channels of one UE by means of logical channel prioritization, and padding. 
     The RLC protocol may include functions such as reordering data packet data, segmentation of data, or reassembly of data, among other examples. The PDCP may include functions such as transferring data to upper layers, integrity protection, ciphering data, or deciphering data, among other examples. RLC protocol or PDCP may be required to transmit data packets in order to the application processor  325 . In some cases, the modem  310  may perform reordering at either the RLC layer  318  or PDCP layer  316  before sending data to upper layers and eventually to the application processor or to a tethered endpoint. For reordering, the UE  302  can store out of order received data packets until the in order sequence is determined. Reassembly of sequences of data packets can be performed within a reassembly timing value that is tracked by a reassembly timer. 
     The MAC layer can package data from logical channels into TBs, and can provide the TBs on one or more transport channels to the physical layer. The physical layer can handle various operations relating to transmission of a data signal, as described in more detail in connection with  FIG.  2   . 
     On the downlink, the operations may be similar to those described for the uplink, but reversed. For example, the physical layer can receive TBs and can provide the TBs on one or more transport channels to the MAC layer. The MAC layer can map the transport channels to logical channels and can provide data to the RLC layer via the logical channels. The RLC layer can map the logical channels to RLC channels and can provide data to the PDCP layer via the RLC channels. The PDCP layer can map the RLC channels to radio bearers and can provide data to the RRC/NAS layer via the radio bearers. 
     Data can be passed between the layers in the form of PDUs and SDUs. An SDU is a unit of data that has been passed from a layer or sublayer to a lower layer. For example, the PDCP layer can receive a PDCP SDU. A given layer can then encapsulate the unit of data into a PDU and can pass the PDU to a lower layer. For example, the PDCP layer can encapsulate the PDCP SDU into a PDCP PDU and can pass the PDCP PDU to the RLC layer. The RLC layer can receive the PDCP PDU as an RLC SDU, can encapsulate the RLC SDU into an RLC PDU, and so on. In effect, the PDU carries the SDU as a payload. 
     Generally, a first layer is referred to as higher than a second layer if the first layer is further from the physical layer than the second layer. For example, the physical layer may be referred to as a lowest layer, and the PDCP/RLC/MAC layer may be referred to as higher than the physical layer and lower than the RRC layer. An application (APP) layer, not shown in  FIG.  3   , may be higher than the PDCP/RLC/MAC layer. In some cases, an entity may handle the services and functions of a given layer (for example, a PDCP entity may handle the services and functions of the PDCP layer), though the description herein refers to the layers themselves as handling the services and functions. 
     In some examples, the UE  302  may include an application processor  325  that can instantiate, for example, one or more applications that consume or generate data packets that are communicated between the UE  302  and the network node  304 . The AP  325  can implement a set  330  of upper layers associated with one or more upper layer protocols such as, for example, TCP or a high level operating system (HLOS) protocol, among other examples. The AP  325  can communicate, via a serial interface  335 , with a hardware acceleration engine  340  that can, for example, include an IP acceleration (IPA) hardware module  345 . The serial interface  335  can include, for example, a peripheral component interconnect express (PCIe) link or an inter-integrated circuit sound bus (I2S), among other examples. A similar serial interface  350  (for example, a PCIe link) can provide an interface between the PDCP layer  316  and an IPA software module  355 . 
     As shown, the DU  314  can implement the set  320  of lower level layers to facilitate transmitting and receiving data packets via the OTA interface  308 . The DU  314  also can implement the RLC layer  318 , which can facilitate RLC communication with the UE  302 . The CU  312  can implement an uplink PDCP module  360  that can communicate with the DU via an interface  362 , such as, for example, an F1-U interface or an NR-U interface, among other examples. Additionally, as shown, the CU  312  can communicate, via an S1U or NG-U interface  364  with the core network  306 . For example, the CU  312  can communicate with a proxy or gateway (shown as “Proxy/GW”)  366  hosted by the core network  306 . The proxy or gateway  366  can communicate, via an S1U interface  368 , with IP services  370 . 
     The core network  306  can provide user authentication, access authorization, tracking, IP connectivity, and other access, routing, or mobility functions. The core network  306  can be an evolved packet core (EPC) or 5G core (5GC), which can include at least one control plane entity that manages access and mobility (for example, a mobility management entity (MME), an access and mobility management function (AMF)) and at least one user plane entity that routes data packets or interconnects to external networks (for example, the proxy or gateway  366 , which can include a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)). The control plane entity can manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs served by the network node s associated with the core network  306 . User IP data packets can be transferred through the user plane entity, which can provide IP address allocation as well as other functions. The user plane entity can be connected to the network operator&#39;s IP services  370 . The network operator&#39;s IP services  366  can include access to the Internet, intranet(s), an IP multimedia subsystem (IMS), or a packet-switched streaming service. 
       FIG.  4    is a diagram illustrating an example of a UE  400  configured to receive downlink data packets, in accordance with the present disclosure. As shown, the UE  400  includes a modem  402  and an application processor  404  (shown as “app processor”). In a first operation  406 , data packets can be processed at the modem (for example, via a transceiver that receives the data packets from an OTA transmission). The data packets can follow either an LTE processing path or an NR processing path through an LTE MAC layer and LTE physical layer  408  or an NR MAC layer and NR physical layer  410  (shown as “LTE-MAC/L1” and “NR-MAC/L1” respectively) and an LTE-RLC layer  412  or an NR-RLC layer  414 . The data packets from both the LTE and NR processing paths can be processed by an NR-PDCP layer  416 , which generates PDCP SDUs. 
     In a second operation  418 , the NR-PDCP layer  416  can provide the data packets to a reordering buffer  420 . The NR-PDCP layer  416  can manage reordering and discarding of PDCP SDUs that are provided from the respective MAC layers of the LTE-MAC/L1  408  and the NR-MAC/L1  410 . Each PDCP SDU can have a corresponding PDCP sequence number (SN) that can be used to reorder PDCP SDUs in consecutive order according to their associated SNs. The NR-PDCP layer  416  can perform reordering by establishing a reordering window that defines a range of PDCP SNs that are eligible for reordering. The length of the reordering window can be referred to as a “reordering timing value.” If a PDCP PDU is received from a MAC layer of the LTE-MAC/L1  408  or the NR-MAC/L1  410  that contains SDUs with PDCP SNs outside of the reordering window, the respective NR-PDCP layer  416  can discard the PDU. The NR-PDCP layer  416  can then process non-discarded PDUs and store associated SDUs in a reordering buffer  420 . The NR-PDCP layer  416  can associate a count value with the SDU that is a concatenation of a hyperframe number (HFN) and PDCP SN (for example, having a 32 bit value), and perform deciphering of the SDU. The NR-PDCP layer  416  can discard SDUs that are duplicated. The NR-PDCP layer  416  can deliver the resultant SDUs to respective upper layers in sequential order according to their associated PDCP SNs. In the event that one or more PDCP SDUs are in the reordering buffer  420  that are not in sequential order, a reordering timer may be initiated. 
     In a wireless communication system, each data packet may incur a source to destination delay different from that experienced by other data packets belonging to the same flow. This variation in delay is known as “jitter.” Jitter creates additional complications for receiver-side applications. If the receiver (for example, the UE  400 ) does not correct for jitter, the received message will suffer distortion when the data packets are re-assembled. The UE  400  can correct for jitter when reconstructing messages from the received data packets. As shown, the application processor  404  (or another component of the UE  400 ) can include a jitter buffer  422 , which adds a wait time, referred to as a jitter buffer delay or jitter buffer timing. 
     Data packets arriving at the jitter buffer  422  can arrive at irregular intervals. One of the design goals of a jitter buffer, therefore, is to adjust for the irregularity of incoming data. As shown in a third operation  424 , data packets are provided from the reordering buffer  420  to the jitter buffer  422 , and a condition referred to as “underflow” can occur. Underflow at the jitter buffer  422  can occur when there are missing data packets. A data packet can be missing when it is lost or delayed. A lost data packet causes an underflow when dropped before it reaches the UE  400 , such as when it is dropped somewhere in the access network, for example on the physical layer or the forward link scheduler. 
     Alternatively, an underflow can occur as a result of a data packet that is delayed and arrives after its playback time. For example, as shown, in the third operation  424 , a set of four data packets (labeled “1,” “2,” “3,” and “4”) transmitted from a network node (represented by time-domain line  426 ) to the UE (represented by time-domain line  428 ) can arrive as indicated by the arrows. Data packets  1  and  2  are received within a jitter buffer timing  430 . Data packet  3  arrives after the jitter buffer timing  430  and, as a result, is discarded. If data packet  4  is received within a next jitter buffer timing (not shown), for example, data packets  1 ,  2  and  4  can be provided to an IMS client  432 , while data packet  3  is missing, resulting in underflow. Underflow can result in missed content, inaccurate data, dropped calls, or application errors. The jitter buffer  422  can be used for IMS content such as, for example, voice frames or video frames, among other examples. 
     As shown, the reordering buffer can deliver other data packets such as, for example, TCP data PDUs to a data Linux module  434  via an IP hardware block  436  in a fourth operation  438 . In a fifth operation  440 , the data Linux module  434  can deliver the data packets from the data Linux module  434  to a network protocol stack  442  (shown as “NW stack”). 
     When a reordering timer is configured to a much higher value than a reassembly timer for an IMS bearer, this can lead to unnecessary holding of data packets at the NR-PDCP  416 . As a result, the NR-PDCP  416  can deliver data packets to the jitter buffer  422  with a delay of more than a configured jitter buffer timing value. Because IMS traffic is prone to data packet loss and, as there is no retransmission at the RLC level, there is no value in holding a data packet beyond a reassembly timer expiry in a non-dual connectivity use case. Different applications like games, extended reality applications, augmented reality applications, or virtual reality applications, among other examples, can have different jitter buffer requirements and processing requirements based on the software or hardware interconnect entities involved or processing in external hardware or software blocks with different schedulers. 
     Jitter management and modem timers such as the reassembly timer and the reordering timer are often independently configured by the network, which may lead to delayed real-time transport protocol (RTP) packet delivery to the IMS application. Though quality of service (QoS) mechanisms are outlined in some wireless communication standards to facilitate coordinated configuration, radio level RLC/PDCP configuration (at the network node) is configured to achieve average latency requirements rather than peak latency requirements that can be associated with the IMS application. Additionally, the physical layer radio conditions and location of the UE can cause challenges with ensuring successful transmission and reception at the physical layer level. If modem timers are configured such that data packet delivery from the modem to the IMS application causes enough delay to overshoot the jitter buffer timing, underflow can result, causing a poor user experience, even when the modem attempts to successfully recover the data packets with proactive retransmissions or duplications at MAC/RLC levels. 
     Various aspects relate generally to delivering data packets with a timing to achieve a balance between delivering data packets in time and delivering data packets with minimal loss. Some aspects more specifically relate to modifying configured modem timers based at least in part on jitter timing values associated with applications. In some aspects, a UE may generate at least one modified timing value corresponding to at least one modem timer by modifying at least one configured timing value corresponding to the at least one modem timer based at least in part on a jitter timing value associated with an application that is instantiated on the UE. In some aspects, the UE may receive at least one data packet based at least in part on the at least one modified timing value. 
     Particular aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, the described techniques can be used to reduce underflow of jitter buffers, thereby resulting in fewer lost data packets and, as a result, a positive impact on user experience. 
       FIG.  5    is a diagram illustrating an example  500  associated with modifying modem timers based on jitter timing associated with an application, in accordance with the present disclosure. As shown in  FIG.  5   , a UE  505  and a network node  510  may communicate with one another. In some aspects, the UE  505  may be, or be similar to, the UE  400  depicted in  FIG.  4   , the UE  302  depicted in  FIG.  3   , or the UE  120  depicted in  FIGS.  1  and  2   . In some aspects, the network node  510  may be, or be similar to, the network node  304  depicted in  FIG.  3    or the network node  110  depicted in  FIGS.  1  and  2   . 
     In a first operation  515 , the network node  510  may transmit, and the UE  505  may receive, a timer configuration. The timer configuration may indicate at least one configured timing value. The at least one configured timing value may be a configured timing value of a modem timer such as, for example, a reordering timer or a reassembly timer. 
     In a second operation  520 , the UE  505  may generate at least one modified timing value corresponding to at least one modem timer by modifying at least one configured timing value corresponding to the at least one modem timer based at least in part on a jitter timing value associated with an application that is instantiated on the UE  505 . In some aspects, the at least one modem timer may include a reordering timer and a reassembly timer. The application may be associated with an IMS. In some aspects, the application may include at least one of an extended reality application, a virtual reality application, or an augmented reality application. 
     In some aspects, the at least one modified timing value may include a modified reordering timing value corresponding to the reordering timer and a modified reassembly timing value corresponding to the reassembly timer. The at least one modified timing value may be based at least in part on a relationship between the modified reordering timing value and the modified reassembly timing value. For example, the modified reordering timing value may be equal to a first product, TJitter*N, of the jitter timing value TJitter and a value of a first variable N. In some aspects, the value of N may be a percentage or a decimal representation of a percentage. 
     The value of the first variable N may be based at least in part on at least one of a location of a jitter buffer or a processing delay associated with the jitter buffer. In some aspects, the processing delay may correspond to an interface between an IPA and a direct memory access component. For example, in some aspects, the processing delay may correspond to at least one of an I2S interface, a PCIe connection, or a scheduler. 
     In some aspects, the first product TJitter*N may be greater than, or equal to, a sum of a second variable X and a second product M*Treassembly of the modified reassembly timing value Treassembly and a value of a third variable M. For example, the at least one modified timing value may be based at least in part on a relationship that indicates that TJitter*N %=Treorder&gt;=M*Treassembly+X. 
     In some aspects, the value of the second variable X may include a retransmission timing value. In some aspects, at least one of the value of the first variable Nor the value of the second variable X may be based at least in part on at least one of: a connection type of a communication connection between the UE  505  and a network node (for example, the network node  510 ), or a processing parameter associated with the application. In some aspects, the third variable M may include a coefficient that is based on an RLC mode. For example, the coefficient may be equal to one (M=1) based at least in part on the RLC mode being an un-acknowledge mode (UM), or greater than or equal to one (M&gt;1) based at least in part on the RLC mode being an acknowledge mode (AM). 
     In some aspects, the coefficient may be based at least in part on a number of RLC automatic repeat requests associated with the application. The modified reassembly timing value may be based at least in part on an average value of a set of hybrid automatic repeat request (HARQ) latency time values between retransmissions. In some aspects, the modified reordering timing value may be based at least in part on a sum of a processing delay value and the modified reassembly timing value. In some aspects, the processing delay value may be based at least in part on a processing architecture. The processing delay value may correspond to a processing delay between an interface unit hardware component and an interface unit software component.
