Abstract

Various aspects of the present disclosure relate generally to wireless communications. In some aspects, a user equipment (UE) may identify an SR opportunity in which a scheduling request (SR) for uplink resources in which one or more packets are to be sent is to be sent based at least in part on a determination about sending one or more packets, the SR opportunity occurring before the start of a connected discontinuous reception (CDRX) on duration of the UE. The UE may determine whether the SR opportunity occurs within a threshold amount of time before the start of the CDRX on duration of the UE. The UE may send an SR in the SR opportunity based at least in part on a determination about whether the SR opportunity occurs within a threshold amount of time before the start of the CDRX on duration of the UE. Many other aspects are provided.

Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques for identifying scheduling request opportunities for discontinuous reception of a connection. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). 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 released by the Third Generation Partnership Project (3GPP).

[0005] A wireless communication network may include multiple base stations (BSs) that can support communications for multiple user equipments (UEs). User equipments (UEs) may communicate with base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to a communication link from a BS to a UE, while an uplink (or reverse link) refers to a communication link from a UE to a BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, access point (AP), radio head, transmit receive point (TRP), new radio (NR) BS, 5G Node B, etc.

[0006] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user devices to communicate at city, country, region, and even global levels. New Radio (NR) (which may also be referred to as 5G) is an enhancement set to the LTE mobile standard released by the Third Generation Partnership Project (3GPP). NR is designed to be better integrated with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink (DL), using CP-OFDM and / or SC-FDM (e.g., also referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), so as to better support mobile broadband Internet access, as well as support beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. However, as the demand for mobile broadband access continues to grow, there is a need for further improvements in LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunication standards that employ these technologies. Summary of the invention

[0039] The following is a more complete description of various aspects of the present disclosure with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be construed as being limited to any specific structure or function presented throughout the present disclosure. More specifically, these aspects are provided so that the present disclosure will be thorough and complete, and the scope of the present disclosure will be fully conveyed to those skilled in the art. Based on the teachings herein, it should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether the aspect is implemented independently of any other aspect of the present disclosure or implemented in combination with any other aspect. For example, using any number of aspects set forth herein, a device can be implemented or a method can be implemented. In addition, the scope of the present disclosure is intended to cover such a device or method implemented using other structures, functions, or structures and functions other than the various aspects of the present disclosure set forth herein or different from the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of the claims.

[0040] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices 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, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0041] It should be noted that although terms commonly associated with 3G and / or 4G wireless technologies may be used herein to describe various aspects, various aspects of the present disclosure may be applicable to communication systems based on other generations, such as 5G and beyond (including NR technologies).

[0042] Figure 11 is a diagram showing a wireless network 100 in which various aspects of the present disclosure may be implemented. The wireless network 100 may be an LTE network or some other wireless network, such as a 5G or NR network. The wireless network 100 may include a plurality of BSs 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, transmit receive point (TRP), etc. Each BS may provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to a coverage area of ​​a BS and / or a BS subsystem serving the coverage area, depending on the context in which the term is used.

[0043] 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 residence) and may allow restricted access by UEs associated 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 Figure 1 In the example shown in , BS 110a may be a macro BS for macro cell 102a, BS 110b may be a pico BS for pico cell 102b, and BS 110c may be a femto BS for femto cell 102c. A BS may support one or more (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.

[0044] In some aspects, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile BS. In some aspects, the BSs may be interconnected with each other and / or with one or more other BSs or network nodes (not shown) in the wireless network 100 via various types of backhaul interfaces (e.g., direct physical connections, virtual networks, and / or similar interfaces using any suitable transport networks).

[0045] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and send data transmissions to a downstream station (e.g., a UE or a BS). A relay station may also be a UE that is capable of relaying transmissions for other UEs. Figure 1 In the example shown in , a relay station 110d may communicate with a macro BS 110a and a UE 120d to facilitate communication between the BS 110a and the UE 120d. A relay station may also be referred to as a relay BS, a relay base station, a relay, or the like.

[0046] The wireless network 100 may be a heterogeneous network including different types of BSs (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs may have different transmit power levels, different coverage areas, and different effects on interference in the wireless network 100. For example, a macro BS may have a high transmit power level (e.g., 5 to 40 watts), while a pico BS, a femto BS, and a relay BS may have a lower transmit power level (e.g., 0.1 to 2 watts).

[0047] A network controller 130 may be coupled to a set of BSs and may provide coordination and control for these BSs. The network controller 130 may communicate with the BSs via a backhaul. The BSs may also communicate with each other via a wireless or wired backhaul (eg, directly or indirectly).

[0048] UE 120 (e.g., 120a, 120b, 120c) can be dispersed throughout the wireless network 100, and each UE can be stationary or mobile. UE can also be referred to as an access terminal, terminal, mobile station, subscriber unit, station, etc. UE can 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 device, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or apparatus, a biometric sensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), an entertainment device (e.g., a music or video device, or a satellite radio unit, etc.), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0049] Some UEs may be considered as 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, etc., which may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide a connection to a network (e.g., a wide area network such as the Internet or a cellular network) or a connection to a network, for example, via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NB-IoT (narrowband Internet of Things) devices. Some UEs may be considered as customer premises equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120 (such as a processor component, a memory component, etc.).

[0050] Generally, any number of wireless networks can be deployed in a given geographic area. Each wireless network can support a specific RAT and can operate on one or more frequencies. RAT can also be referred to as radio technology, air interface, etc. Frequency can also be referred to as carrier, frequency channel, etc. Each frequency can support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0051] 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 base station 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocol (e.g., which may include vehicle-to-vehicle (V2V) protocol, vehicle-to-infrastructure (V2I) protocol, etc.), mesh network, etc. In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0052] As noted above, Figure 1 is provided as an example. Other examples may differ from those described above. Figure 1 Examples described.

[0053] Figure 2 Base station 110 and UE 120 (which may be Figure 11. Block diagram of a design 200 of a base station 110 and a UE 120. 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.

[0054] At the base station 110, the transmit processor 220 may receive data for one or more UEs from the data source 212, select one or more modulation and coding schemes (MCS) for each UE based at least in part on a channel quality indicator (CQI) received from the UE, process (e.g., encode and modulate) the data for the UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.), and provide overhead symbols and control symbols. The transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signals (PSS) and secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide T output symbol streams to T modulators (MOD) 232a to 232t. Each modulator 232 may process a corresponding output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. T downlink signals from modulators 232a to 232t may be transmitted via T antennas 234a to 234t, respectively. According to various aspects described in more detail below, a synchronization signal may be generated using position coding to transmit additional information.

[0055] At UE 120, antennas 252a to 252r may receive downlink signals from base station 110 and / or other base stations, and may provide received signals to demodulators (DEMODs) 254a to 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, downconvert, and digitize) the received signal to obtain input samples. Each demodulator 254 may further process the input samples (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 may obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide detected symbols. Receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The channel processor may determine reference signal received power (RSRP), received signal strength indicator (RSSI), reference signal received quality (RSRQ), channel quality indicator (CQI), etc. In some aspects, one or more components of UE 120 may be included in a housing.

[0056] On the uplink, at the UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information from a controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also 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 modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the base station 110. At the base station 110, uplink signals from the UE 120 and other UEs may be received by the antenna 234, processed by the demodulator 232, detected by the MIMO detector 236 (if applicable), and further processed by the receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide decoded data to a data sink 239 and provide decoded control information to a controller / processor 240. The base station 110 may include a communication unit 244 and communicate with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0057] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2Any (one or more) other components of the may perform one or more techniques associated with identifying a scheduling request (SR) opportunity for connected discontinuous reception (CDRX), as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component(s) may perform or direct e.g. Figure 4 The operations of process 400 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 for wireless communication. For example, when executed by one or more processors of base station 110 and / or UE 120, the one or more instructions may perform or direct, for example, Figure 4 The scheduler 246 may schedule UEs for data transmission on the downlink and / or uplink.

[0058] In some aspects, the UE 120 may include: means for identifying an SR opportunity in which to send an SR for uplink resources in which the one or more packets are to be sent based at least in part on a determination to send the one or more packets, the SR opportunity occurring before the start of a CDRX On Duration of the UE; means for determining whether the SR opportunity occurs within a threshold amount of time before the start of the CDRX On Duration of the UE; means for sending the SR in the SR opportunity based at least in part on a determination whether the SR opportunity occurs within a threshold amount of time before the start of the CDRX On Duration of the UE; and the like. In some aspects, such means may include combining Figure 2 One or more components of UE 120 are depicted, such as controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0059] As noted above, Figure 2 is provided as an example. Other examples may be related to Figure 2 The examples described are different.

[0060] The UE may be enabled for voice over LTE (VoLTE), voice over NR (VoNR), and / or another packet-based voice operation, which enables the UE to send voice information in packets (e.g., on an LTE channel, on a 5G / NR channel, etc.). The UE may include an audio layer and a modem layer. The audio layer may generate voice information. When the voice information is ready for transmission, the audio layer may send the voice information to the modem layer. The modem layer may encode the voice information and send the voice information as packets over an LTE or 5G / NR wireless network.

[0061] To send a packet, the modem layer of the UE may send an SR to the BS. The SR may be a request for uplink resources (e.g., time domain resources, such as symbols, time slots, etc., and / or frequency domain resources, such as subcarriers, component carriers, etc.) in which the UE may send packets. The modem layer may receive an uplink scheduling grant based at least in part on sending the SR, the uplink scheduling grant being used to schedule uplink resources for the UE.

[0062] In some cases, the modem layer may be configured based on a CDRX cycle, wherein the UE periodically switches to a CDRX on mode within a CDRX on duration to monitor downlink transmissions (e.g., from a BS), and then returns to a CDRX sleep mode until the next CDRX cycle. In this case, the audio layer and the modem layer of the UE may operate asynchronously, which may result in reduced performance and efficiency of the CDRX operation of the UE. For example, the audio layer may send voice information to the modem layer at a timing that causes the UE to switch out of the CDRX sleep cycle too early to send an SR for sending a packet carrying voice information. As another example, the audio layer may send voice information to the modem layer at a timing that causes the modem to send an SR too early before the CDRX on duration of the UE. In either case, the CDRX operation of the UE may be interrupted, which may result in reduced performance and efficiency of the CDRX operation of the UE, may reduce the battery performance of the UE, etc.

[0063] Furthermore, because the BS may coordinate with the CDRX operation of the UE, the UE may send an SR in an SR opportunity that the BS does not expect the UE to send an SR in (e.g., because the BS expects the UE to be in CDRX sleep mode during the SR opportunity). As a result, the BS may not monitor the SR opportunity and may not receive the SR in the SR opportunity. Therefore, processing, memory, and radio resources are wasted in sending an SR in an SR opportunity that is not monitored by the BS.

[0064] Some aspects described herein provide techniques for identifying SR opportunities for CDRX. In some aspects, a UE is capable of identifying an SR opportunity in which an SR is to be sent based at least in part on an algorithm that takes into account the CDRX operation of the UE. For example, the UE may attempt to identify an SR opportunity that occurs within a threshold amount of time before the UE's CDRX on duration, in which the SR may be sent, and in which other SR opportunities may be avoided. If the UE is unable to identify an SR opportunity that occurs within the threshold amount of time, the UE may attempt to identify an SR opportunity that occurs during the UE's CDRX on duration, in which the SR may be sent, and in which other SR opportunities may be avoided. In this way, the UE is already in CDRX on mode when sending the SR, and does not need to be converted from CDRX sleep mode to send the SR. If the UE is unable to identify an SR opportunity that occurs during the UE's CDRX on duration, the UE may wait until the threshold amount of time before the next CDRX on duration to identify the SR opportunity. In this way, the UE reduces the amount of time the UE wakes up from the CDRX Sleep Mode before the CDRX On Duration and saves processing, memory, battery and radio resources that would otherwise be consumed in sending the SR in other SR opportunities.

[0065] Figures 3A-3E is a diagram illustrating one or more examples 300 of identifying SR opportunities for CDRX according to various aspects of the present disclosure. Figures 3A-3E As shown in , example 300 may include a UE (e.g., UE 120). In some aspects, the UE may communicate with a BS (e.g., BS 110) over a wireless access link, which may include an uplink and a downlink. In some aspects, the UE may be configured to perform CDRX operations such that the UE switches between a CDRX on mode and a CDRX sleep mode according to a CDRX cycle.

[0066] like Figure 3A As shown in , the UE may be configured with multiple types of layers. These layers may be implemented by one or more components of the UE, such as a receiving processor (e.g., receiving processor 258), a data source (e.g., data source 262), a transmitting processor (e.g., transmitting processor 264), a controller / processor (e.g., controller / processor 280), a memory (e.g., memory 282), a modem implemented by one or more of a receiving processor, a transmitting processor, a controller / processor, and / or a memory, and the like.

[0067] In some aspects, these layers may include a voice layer and a modem layer. The voice layer may be implemented by a controller / processor, a memory, a data source, and / or other components. The low power audio subsystem (LPASS) of the voice layer may generate and receive voice information (e.g., voice call information, VoLTE information, VoNR information, etc.), may provide voice information to other layers of the UE, and so on. The LPASS may provide voice information to other layers of the UE using mailbox technology, which may include storing the voice information in a shared memory so that the voice information may be retrieved by other layers of the UE.

[0068] The modem layer may be composed of a non-access stratum (NAS) layer and an access stratum (AS) layer. The NAS layer may include an Internet Protocol (IP) Multimedia Subsystem (IMS) layer, where packetization of voice information occurs. In this case, the UE's modem (e.g., implemented by a receive processor, a transmit processor, a controller / processor, a memory, etc.) may retrieve the voice information from a shared memory and may perform real-time protocol (RTP) packetization of the voice information to generate packets (e.g., voice packets) carrying the voice information. The packets may be provided to the AS layer of the modem, which may include layers 1-3 (e.g., a physical layer, a transport layer, a user datagram protocol (UDP) / IP layer, etc.). At layers 1-3, the modem may process the packets for transmission to the BS over a wireless access link.

[0069] As in Figure 3A In the embodiment and shown by reference numeral 302, in order to ensure that the modem layer and the voice layer are synchronized with the CDRX operation of the UE, the AS layer of the modem can provide an indication of one or more parameters of the modem to the NAS layer. In some aspects, the one or more parameters can include an uplink packet offset time, which can be an amount of time it takes for the modem to receive a packet and transmit the packet on the uplink. The uplink packet offset time ensures that the voice layer provides the voice information to the modem layer early enough in advance for the modem layer to wake up, process, and send an SR for the packet carrying the voice information.

[0070] The uplink packet offset time may be based at least in part on the uplink processing parameters of the modem, the wake-up processing time of the modem, and the timing of the SR opportunity configured for the UE. The uplink processing parameters may indicate the amount of time used to perform layer 1-3 processing of the packet. The wake-up processing time may indicate the amount of time it takes for the modem to wake up and be ready to send a packet. The timing of the SR opportunity may indicate the amount of time between the SR opportunity and the CDRX on duration of the UE.

[0071] In some aspects, the one or more parameters may include a downlink processing time parameter, which may indicate the amount of time the modem takes to process a downlink packet received at the UE. In some aspects, the one or more parameters include one or more CDRX parameters associated with the CDRX operation of the UE. The one or more CDRX parameters may include a CDRX cycle length (e.g., which may specify the duration of a periodic CDRX cycle of the UE), a CDRX cycle start time (e.g., which may specify the symbol, time slot, etc. at which the CDRX cycle of the UE will start), a CDRX onDurationtimer value (e.g., the duration of the CDRX on duration of the UE), etc.

[0072] As in Figure 3A In and further shown by reference numeral 304, the NAS layer of the modem can receive an indication of one or more parameters and can provide an indication of one or more modem parameters to a voice layer (e.g., LPASS). In some aspects, the one or more modem parameters can include a Tx_Ref_Time parameter, which can correspond to an uplink packet offset time indicated by the AS layer. In some aspects, the one or more modem parameters can include an Rx_Ref_Time parameter, which can be an indication of an amount of time after which a packet or frame received can be used for decoding. The Rx_Ref_Time parameter can be based at least in part on a downlink processing time parameter indicated by the AS layer and a CDRX onDurationtimer value. In some aspects, the one or more modem parameters can include a CDRX_cycle parameter, which can indicate one or more of the CDRX parameters indicated by the AS layer.

[0073] The modem of the UE may receive voice information from the audio layer (e.g., based at least in part on one or more modem parameters), may generate one or more packets (e.g., voice packets) carrying the voice information in the IMS layer of the NAS layer of the modem layer of the UE, and may provide the one or more packets to the AS layer of the modem layer. At the AS layer of the modem layer, the modem may identify an SR opportunity in which to send an SR for uplink resources for sending the one or more packets.

[0074] like Figure 3B As shown in , a UE may be configured with an SR opportunity periodicity, where an SR opportunity for the UE occurs at a specific time. As an example, and as Figure 3BAs shown in , the UE may be configured with a 10 ms SR opportunity periodicity, where an SR opportunity occurs every 10 ms (e.g., at 24 ms, at 34 ms, etc.). In some aspects, the UE may be configured with other SR opportunity periodicities, such as a 20 ms SR opportunity periodicity, etc.

[0075] like Figure 3B As further shown in FIG. 1 , the UE may be configured with a CDRX offset of 36 milliseconds, in which case the CDRX cycle starts at 36 milliseconds (e.g., 36 milliseconds into the radio frame or relative to another starting point). The CDRX cycle length may be a cycle length of 40 milliseconds (e.g., Figure 3B The UE's CDRX onDurationtimer may be set to 10 milliseconds and / or another value, which may determine the amount of time the UE remains in CDRX on mode.

[0076] like Figure 3B As further shown in , an example Tx_Ref_Time (e.g., uplink packet offset time) for a modem may be 11 milliseconds based at least in part on an uplink processing time (UL-P) of 3 milliseconds, an SR offset of 2 milliseconds (e.g., 2 milliseconds between SR opportunities before the first physical downlink control channel (PDCCH) opportunity of the UE's CDRX on duration), and a wake-up processing time (WUT) of 6 milliseconds. Figure 3B As further shown in , an example Rx_Ref_Time for a modem may be 13 milliseconds based at least in part on a CDRX onDurationtimer value of 10 milliseconds and a downlink processing time (DL-P) of 3 milliseconds.

[0077] like Figure 3B As further shown in , the CDRX on duration of a UE may include an example configuration of a PDCCH opportunity in which the UE may receive PDCCH communications and a physical downlink shared channel (PDSCH) opportunity in which the UE may receive PDSCH communications. In some aspects, the PDCCH opportunity may be front-loaded in the CDRX on duration, in which case the PDSCH opportunity may follow the PDCCH opportunity.

[0078] Figure 3C-3E One or more example aspects of an algorithm for identifying an SR opportunity at which to send an SR for one or more packets are shown. Figure 3CIn and as indicated by reference numeral 306, the UE may identify a first SR opportunity that occurs prior to the start of the UE's CDRX on-duration (e.g., prior to a first PDCCH opportunity). In some aspects, the UE may identify the first SR opportunity that occurs in time after the UE's modem receives one or more packets. Figure 3C In the example shown in , the modem may receive one or more packets at 24 milliseconds, in which case the first SR opportunity may be the SR opportunity occurring at 34 milliseconds.

[0079] As in Figure 3C In the embodiment and further indicated by reference numeral 308, the UE may determine whether the first SR opportunity occurs within a threshold amount of time before the start of the CDRX On Duration. The threshold amount of time may include one or more milliseconds before the start of the CDRX On Duration and may be specified to ensure that there is sufficient time to process one or more packets and send the SR before the SR opportunity. In addition, the threshold amount of time may be specified to ensure that the SR opportunity selected by the UE is close enough to the start of the CRDX On Duration so that the UE does not wake up from the CDRX sleep mode too early to send the SR, thereby preserving the power saving characteristics of the CDRX operation.

[0080] like Figure 3C As shown in , an example threshold time amount may be 5 milliseconds before the start of the CDRX On Duration. In this case, the UE may determine whether the first SR opportunity occurs within 5 milliseconds of the start of the CDRX On Duration. In some aspects, the threshold time amount may be greater than 5 milliseconds. In some aspects, the threshold time amount may be less than 5 milliseconds.

[0081] As in Figure 3C 3 and further indicated by reference numeral 310, the UE may send the SR in the first SR opportunity based at least in part on a determination as to whether the first SR opportunity occurs within a threshold amount of time. If the UE determines that the first SR opportunity occurs within the threshold amount of time before the start of the CDRX On Duration, the UE may send the SR in the first SR opportunity. As an example, if the first SR opportunity occurs 2 milliseconds before the start of the CDRX On Duration (e.g., Figure 3C ), the UE may send an SR in the first opportunity if the threshold time amount is 5 milliseconds. The UE may avoid sending an SR for one or more packets in other SR opportunities to avoid exiting the CDRX sleep mode to send an SR, thereby saving processing, memory, battery, and radio resources, etc.

[0082] If the UE determines that the first SR opportunity does not occur within a threshold amount of time before the start of the CDRX On Duration, the UE may avoid sending an SR in the first SR opportunity. As an example, if the first SR opportunity occurs 7 milliseconds before the start of the CDRX On Duration, the UE may avoid sending an SR in the first SR opportunity if the threshold amount of time is 5 milliseconds.

[0083] As in Figure 3D In the example and as indicated by reference numeral 312, if the UE avoids sending an SR in the first SR opportunity, the UE may identify a second SR opportunity that occurs after the first SR opportunity. The second SR opportunity may be the next SR opportunity after the first SR opportunity in the SR opportunity periodicity for the UE. Figure 3D In the example shown in , the second SR opportunity may be the SR opportunity occurring at 44 milliseconds.

[0084] As in Figure 3D In and further indicated by reference numeral 314, the UE may determine whether the second SR opportunity occurs during the CDRX on duration of the UE. In this case, the UE may determine whether the second SR opportunity occurs when the UE is in the CDRX on mode.

[0085] As in Figure 3D In the embodiment and further indicated by reference numeral 316, the UE may send the SR in the second SR opportunity based at least in part on whether the second SR opportunity occurs during the CDRX On Duration. If the UE determines that the second SR opportunity occurs during the CDRX On Duration (e.g. Figure 3D ), the UE may send an SR in the second SR opportunity. The UE may avoid sending an SR for one or more packets in other SR opportunities to avoid exiting the CDRX sleep mode to send an SR, thereby saving processing, memory, battery, and radio resources, etc.

[0086] If the UE determines that the second SR opportunity does not occur during the CDRX On Duration, the UE may avoid sending the SR in the second SR opportunity. For example, if the UE determines that the second SR occurs after expiration of the CDRX On Duration, the UE may avoid sending the SR in the second SR opportunity.

[0087] As in Figure 3E If the UE avoids sending an SR in the second SR opportunity, the UE may identify a third SR opportunity that occurs after the second SR opportunity and as indicated by reference numeral 318. For example, the third SR opportunity may be an SR opportunity at 54 ms, at 64 ms, or at 74 ms.

[0088] As in Figure 3EIn and further indicated by reference numeral 320, the UE may determine whether the third SR opportunity occurs within a threshold amount of time before the start of a next CDRX On Duration of a next CDRX cycle of the UE. In some aspects, the UE may determine whether the third SR opportunity occurs during the next CDRX On Duration of a next CDRX cycle of the UE.

[0089] As in Figure 3E In the embodiment and further indicated by reference numeral 322, the UE may send the SR in the third SR opportunity based at least in part on a determination as to whether the third SR opportunity occurs within a threshold amount of time before the start of the next CDRX On Duration and / or based at least in part on a determination as to whether the third SR opportunity occurs during the next CDRX On Duration. For example, if the third SR opportunity is a SR opportunity occurring at 54 milliseconds, the UE may avoid sending the SR in the third SR opportunity because the SR opportunity occurring at 54 milliseconds does not occur within the threshold amount of time before the start of the next CDRX On Duration and does not occur during the next CDRX On Duration.

[0090] As another example, if the third SR opportunity is an SR opportunity occurring at 64 milliseconds, the UE may avoid sending an SR in the third SR opportunity because the SR opportunity occurring at 64 milliseconds does not occur within the threshold amount of time before the start of the next CDRX On Duration and does not occur during the next CDRX On Duration. As another example, if the third SR opportunity is an SR opportunity occurring at 74 milliseconds, the UE may send an SR, and the UE may send an SR in the third SR opportunity because the SR opportunity occurring at 74 milliseconds occurs within the threshold amount of time before the start of the next CDRX On Duration.

[0091] In this manner, the UE is able to identify an SR opportunity in which to send an SR based at least in part on an algorithm that takes into account the CDRX operation of the UE. In this manner, the UE reduces the amount of time the UE wakes up from the CDRX sleep mode before the CDRX on duration and saves processing, memory, battery, and radio resources that would otherwise be consumed in sending an SR in other SR opportunities that are more likely to fail.

[0092] As noted above, Figures 3A-3E is provided as one or more examples. Other examples may be related to Figures 3A-3E The examples described are different.

[0093] Figure 44 is a diagram illustrating an example process 400 performed, for example, by a UE in accordance with various aspects of the present disclosure. Example process 400 is an example of a UE (eg, UE 120) performing operations associated with identifying SR opportunities for CDRX.

[0094] like Figure 4 As shown in , in some aspects, process 400 may include: identifying, based at least in part on a determination to send one or more packets, an SR opportunity at which to send an SR for uplink resources to send the one or more packets, the SR opportunity occurring before the start of a CDRX On Duration of the UE (block 410). For example, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may identify, based at least in part on a determination to send one or more packets, an SR opportunity at which to send an SR for uplink resources to send the one or more packets, the SR opportunity occurring before the start of a CDRX On Duration of the UE, as described above.

[0095] like Figure 4 As further shown in FIG. 4 , in some aspects, process 400 may include determining whether the SR opportunity occurs within a threshold amount of time before the start of the CDRX On Duration of the UE (block 420). For example, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may determine whether the SR opportunity occurs within a threshold amount of time before the start of the CDRX On Duration of the UE, as described above.

[0096] like Figure 4 As further shown in FIG. 4 , in some aspects, process 400 may include sending the SR in the SR opportunity based at least in part on a determination as to whether the SR opportunity occurs within a threshold amount of time before the start of the CDRX On Duration of the UE (block 430). For example, the UE (e.g., using receive processor 258, transmit processor 264, controller / processor 280, memory 282, etc.) may send the SR in the SR opportunity based at least in part on a determination as to whether the SR opportunity occurs within a threshold amount of time before the start of the CDRX On Duration of the UE, as described above.

[0097] Process 400 may include additional aspects, such as any single aspect or any combination of the aspects described below and / or in conjunction with one or more other processes described elsewhere herein.

[0098] In a first aspect, a SR opportunity periodicity configured for the UE comprises a 10 millisecond periodicity or a 20 millisecond periodicity.

[0103] although Figure 4 Example blocks of process 400 are shown, but in some aspects process 400 may include Figure 4 The blocks depicted in the process 400 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks. Additionally or alternatively, two or more blocks of the process 400 may be executed in parallel.

[0104] Figure 55 is a conceptual data flow diagram 500 illustrating data flow between different modules / units / components in an example apparatus 502. The apparatus 502 may be a UE (eg, UE 120). In some aspects, the apparatus 502 includes an SR opportunity identifying component 504, a determining component 506, and / or a sending component 508.

[0105] In some aspects, the sending component 508 may determine to send one or more packets to the BS 550 (e.g., BS 110). In some aspects, the sending component 508 may determine to send the one or more packets based at least in part on receiving the one or more packets at the modem of the device 502. In some aspects, the sending component 508 may receive the one or more packets from the IMS layer of the device 502 or the modem of the device 502. The IMS layer may be part of the layer of the non-access layer of the modem. In this case, the sending component 508 may receive the one or more packets at one or more access layer layers (e.g., UDP / IP or layer 3 layer, layer 2 layer, layer 1 layer, etc.) of the modem. In some aspects, the sending component 508 may include a sending processor (e.g., the sending processor 264), a controller / processor (e.g., the controller processor 280), a memory (e.g., the memory 282), a modem implemented by one or more of the sending processor, the controller / processor, and / or the memory, etc.

[0106] In some aspects, the SR opportunity identification component 504 can identify a first SR opportunity in which to send an SR 510 for uplink resources in which one or more packets are to be sent. In some aspects, the first SR opportunity can occur before the start of the CDRX on-duration of the device 502. In some aspects, the SR opportunity identification component 504 can determine the first SR opportunity based at least in part on the determination of the transmission component 508 to send the one or more packets. In some aspects, the SR opportunity identification component 504 can include a receive processor (e.g., receive processor 258), a transmit processor (e.g., transmit processor 264), a controller / processor (e.g., controller processor 280), a memory (e.g., memory 282), a modem implemented by one or more of the receive processor, the transmit processor, the controller / processor, and / or the memory, etc.

[0107] In some aspects, determining component 506 can determine whether the first SR opportunity occurs within a threshold amount of time before the start of the CDRX On-Duration of the apparatus 502. In some aspects, determining component 506 can include a receive processor (e.g., receive processor 258), a transmit processor (e.g., transmit processor 264), a controller / processor (e.g., controller processor 280), a memory (e.g., memory 282), a modem implemented by one or more of the receive processor, the transmit processor, the controller / processor, and / or the memory, and the like.

[0108] In some aspects, the sending component 508 can send the SR 510 in the first SR opportunity based at least in part on a determination as to whether the first SR opportunity occurs within a threshold amount of time before the start of the CDRX On Duration of the apparatus 502. For example, the determining component 506 can determine that the first SR opportunity occurs within a threshold amount of time before the start of the CDRX On Duration of the apparatus 502, and the sending component 508 can send the SR 510 in the first SR opportunity based at least in part on a determination by the determining component 506 that the first SR opportunity occurs within the threshold amount of time before the start of the CDRX On Duration of the apparatus 502. As another example, the determining component 506 can determine that the first SR opportunity does not occur within the threshold amount of time before the start of the CDRX On Duration of the apparatus 502, and the sending component 508 can refrain from sending the SR 510 in the first SR opportunity based at least in part on a determination by the determining component 506 that the first SR opportunity does not occur within the threshold amount of time before the start of the CDRX On Duration of the apparatus 502.

[0109] In some aspects, if determining component 506 determines that the first SR opportunity does not occur within a threshold amount of time before the start of the CDRX On Duration of the apparatus 502, the SR opportunity identifying component 504 can identify a second SR opportunity that occurs after the first SR opportunity. Determining component 506 can determine whether the second SR opportunity occurs during the CDRX On Duration of the apparatus 502. Sending component 508 can send SR 510 in the second SR opportunity based at least in part on the determination by determining component 506 that the second SR opportunity occurs during the CDRX On Duration of the apparatus 502.

[0110] For example, the determining component 506 can determine that the second SR opportunity occurs during the CDRX On Duration of the apparatus 502, and the sending component 508 can send the SR 510 in the second SR opportunity based at least in part on the determination by the determining component 506 that the second SR opportunity occurs during the CDRX On Duration of the apparatus 502. As another example, the determining component 506 can determine that the second SR opportunity does not occur during the CDRX On Duration of the apparatus 502, and the sending component 508 can avoid sending the SR 510 in the second SR opportunity based at least in part on the determination by the determining component 506 that the second SR opportunity does not occur during the CDRX On Duration of the apparatus 502.

[0111] In some aspects, if the determining component 506 determines that the second SR opportunity does not occur during the CDRX On Duration of the apparatus 502, the SR opportunity identifying component 504 can identify a third SR opportunity that occurs after the second SR opportunity. The determining component 506 can determine whether the third SR opportunity occurs within a threshold amount of time before another CDRX On Duration in another CDRX cycle of the apparatus 502. The sending component 508 can send the SR 510 in the third SR opportunity based at least in part on the determination by the determining component 506 of whether the third SR opportunity occurs within a threshold amount of time before another CDRX On Duration in another CDRX cycle of the apparatus 502.
