Description

CONFIGURING A SCHEDULING REQUEST RESOURCE FOR AN ALARM MODE OF A USER EQUIPMENT

FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for configuring a scheduling request resource for an alarm mode of a user equipment.

BACKGROUND

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

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

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

DETAILED DESCRIPTION

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

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

It should be noted that while aspects may be described herein using terminology commonly associated with 3G and/or 4G wireless technologies, aspects of the present disclosure can be applied in other generation-based communication systems, such as 5G and later, including NR technologies.

Fig. 1 is a diagram illustrating a wireless network 100 in which aspects of the present disclosure may be practiced. 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 number 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 user equipment (UEs) and may also be referred to as a base station, a NR BS, a Node B, a gNB, a 5G node B (NB) , an access point, a transmit receive point (TRP) , and/or the like. Each BS may provide communication coverage for a particular geographic area. In 3GPP, the term “cell” can refer to a coverage area of a BS and/or a BS subsystem serving this coverage area, depending on the context in which the term is used.

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

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

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

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

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

UEs 120 (e.g., 120a, 120b, 120c) may be dispersed throughout wireless network 100, and each UE may be stationary or mobile. A UE may also be referred to as an access terminal, a terminal, a mobile station, a subscriber unit, a station, and/or the like. A UE may be a cellular phone (e.g., a smart phone) , a personal digital assistant (PDA) , a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, biometric sensors/devices, wearable devices (smart watches, smart clothing, smart glasses, smart wrist bands, smart jewelry (e.g., smart ring, smart bracelet) ) , an entertainment device (e.g., a music or video device, or a satellite radio) , a vehicular component or sensor, smart meters/sensors, industrial manufacturing equipment, a global positioning system device, or any other suitable device that is configured to communicate via a wireless or wired medium.

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

In some aspects, a UE may include a video camera or another type of video capture device. In some aspects, the wireless network may support a large number of video cameras via large capacity MTC services. Large capacity MTC services may be tailored for video for public services (e.g., city surveillance, vehicle traffic monitoring, and/or the like) , video for factory services (e.g., fish farm monitoring, mining supervision, and/or the like) with low cost and high efficiency. Additionally, or alternatively, the wireless network may support Mbps everywhere services, which may include a large number of UEs and/or CPEs with fixed QoS uploading. For example, the wireless network may support a large number of video streams and/or video cameras (e.g., 20 or more streams and/or cameras, 100 or more streams and/or cameras) at high data rates (e.g., 2 Mbps, 25 Mbps, and/or the like) in a relatively small area (e.g., a square kilometer) .

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

In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using a base station 110 as an intermediary to communicate with one another) . For example, the UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, and/or the like) , a mesh network, and/or the like. In this case, the UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station 110.

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

Fig. 2 shows a block diagram of a design 200 of base station 110 and UE 120, which may be one of the base stations and one of the UEs in Fig. 1. Base station 110 may be equipped with T antennas 234a through 234t, and UE 120 may be equipped with R antennas 252a through 252r, where in general T ≥ 1 and R ≥ 1.

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

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

On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports comprising RSRP, RSSI, RSRQ, CQI, and/or the like) from controller/processor 280. Transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modulators 254a through 254r (e.g., for DFT-s-OFDM, CP-OFDM, and/or the like) , and transmitted to base station 110. At base station 110, the uplink signals from UE 120 and other UEs may be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller/processor 240. Base station 110 may include communication unit 244 and communicate to network controller 130 via communication unit 244. Network controller 130 may include communication unit 294, controller/processor 290, and memory 292.

Controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component (s) of Fig. 2 may perform one or more techniques associated with configuring a scheduling request resource for an alarm mode, as described in more detail elsewhere herein. For example, controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component (s) of Fig. 2 may perform or direct operations of, for example, process 700 of Fig. 7, process 800 of Fig. 8, 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 comprise a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, the one or more instructions, when executed by one or more processors of the base station 110 and/or the UE 120, may perform or direct operations of, for example, process 700 of Fig. 7, process 800 of Fig. 8, and/or other processes as described herein. A scheduler 246 may schedule UEs for data transmission on the downlink and/or uplink.

In some aspects, UE 120 may include means for transmitting, to a base station, an indication of a data pattern for uplink data associated with an alarm mode of the UE 120; means for receiving, from the base station, a configuration that indicates a scheduling request resource to be used for the alarm mode based at least in part on transmitting the indication of the data pattern; means for transmitting, to the base station, a scheduling request in the scheduling request resource; means for receiving, from the base station and based at least in part on the scheduling request, an uplink grant that indicates a set of uplink resources to be used for the uplink data associated with the alarm mode; and/or the like. In some aspects, such means may include one or more components of UE 120 described in connection with Fig. 2, such as controller/processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, and/or the like.

In some aspects, base station 110 may include means for receiving, from a UE, an indication of a data pattern for uplink data associated with an alarm mode of the UE;means for transmitting, to the UE, a configuration that indicates a scheduling request resource to be used for the alarm mode based at least in part on receiving the indication of the data pattern; means for receiving, from the UE, a scheduling request in the scheduling request resource; means for transmitting, to the UE and based at least in part on the scheduling request, an uplink grant that indicates a set of uplink resources to be used for the uplink data associated with the alarm mode; and/or the like. In some aspects, such means may include one or more components of base station 110 described in connection with Fig. 2, such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller/processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, and/or the like.

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

Fig. 3 is a diagram illustrating an example 300 of using a buffer status report to allocate uplink resources for uplink data, in accordance with various aspects of the present disclosure. In some aspects, the procedure shown in Fig. 3 may be used when the UE 120 is operating in a normal mode, as described in more detail below. The normal mode may sometimes be referred to as a low throughput operating mode, a non-alarm mode, and/or the like. The procedure shown in Fig. 3 utilizes a buffer status report (BSR) to obtain an uplink grant for uplink data.

As shown in Fig. 3, a UE 120 and a base station 110 may communicate with one another. As shown by reference number 305, the UE 120 may detect that the UE 120 has uplink data for an uplink transmission. The uplink data may be stored in a buffer (e.g., memory) of the UE 120. In some aspects, an application executing on the UE 120 may generate uplink data for transmission, and the UE 120 may detect the uplink data and/or store the uplink data in the buffer (e.g., an uplink buffer) .

As shown by reference number 310, the UE 120 may transmit a scheduling request (SR) to the base station 110 based at least in part on detecting the uplink data in the buffer. The SR may notify the base station 110 that the UE 120 has uplink data for transmission, and may trigger an uplink grant (e.g., an uplink grant for a BSR, as described below) . The UE 120 may transmit the SR in uplink control information (UCI) . The UE 120 may transmit the UCI in a physical uplink control channel (PUCCH) or in a physical uplink shared channel (PUSCH) .

As shown by reference number 315, the base station 110 may transmit an uplink grant for a BSR to the UE 120 based at least in part on receiving the SR. The uplink grant for the BSR may indicate a set of uplink resources (e.g., PUSCH resources) to be used by the UE 120 to transmit the BSR. The base station 110 may transmit the uplink grant for the BSR in downlink control information (DCI) . The base station 110 may transmit the DCI in a physical downlink control channel (PDCCH) .

As shown by reference number 320, the UE 120 may transmit a BSR to the base station 110 based at least in part on receiving the uplink grant for the BSR. For example, the uplink grant may indicate a set of uplink resources (e.g., PUSCH resources) to be used by the UE 120 to transmit the BSR, and the UE 120 may transmit the BSR in the set of uplink resources. The BSR may indicate an amount of uplink data that the UE 120 has stored in a buffer of the UE 120 (e.g., an amount of uplink data ready for transmission to the base station 110) . The base station 110 may use the BSR to allocate an appropriate amount of uplink resources to the UE 120 for transmission of the uplink data.

As shown by reference number 325, the base station 110 may transmit an uplink grant for uplink data to the UE 120 based at least in part on receiving the BSR. The uplink grant for the uplink data may indicate a set of uplink resources (e.g., PUSCH resources) to be used by the UE 120 to transmit the uplink data (e.g., stored in the buffer of the UE 120) . The base station 110 may transmit the uplink grant for the uplink data in DCI. The base station 110 may transmit the DCI in the PDCCH. The base station 110 may determine the quantity of uplink resources to be indicated in the uplink grant for the uplink data based at least in part on the BSR. For example, the base station 110 may allocate a sufficient amount of uplink resources to allow the UE 120 to transmit the uplink data stored in the buffer of the UE 120 (e.g., without over-allocating resources to the UE 120) .

As shown by reference number 330, the UE 120 may transmit the uplink data (e.g., stored in the buffer of the UE 120) to the base station 110 based at least in part on receiving the uplink grant for the uplink data. For example, the uplink grant may indicate a set of uplink resources (e.g., PUSCH resources) to be used by the UE 120 to transmit the uplink data, and the UE 120 may transmit the uplink data in the set of uplink resources.

In some cases, the procedure shown in Fig. 3 may be used to handle bursty data transmissions by the UE 120. In a bursty data transmission, the amount of uplink data to be transmitted in a burst does not typically follow a pattern. However, in some cases, a UE 120 may transmit uplink data bursts according to a pattern (e.g., a data pattern) . As an example, the UE 120 may be a video camera or another type of video capture device. This type of UE 120 may periodically transmit uplink data in a normal mode (e.g., a low throughput operating mode) , and may occasionally transmit bursts of uplink data in an alarm mode (e.g., a high throughput operating mode) . For example, the UE 120 may capture and/or transmit low resolution video traffic to the base station 110 in a normal mode. If the UE 120 detects a triggering event, such as an alarm and/or suspicious activity (e.g., determined based at least in part on analyzing captured video, motion sensing, and/or the like) , then the UE 120 may enter an alarm mode. In the alarm mode, the UE 120 may capture and/or transmit high resolution video traffic to the base station 110. For this reason, the an alarm mode may sometimes be referred to as a high throughput operating mode or a high uplink throughput operating mode.

While an event that triggers the alarm mode may be unpredictable, the uplink data transmitted during the alarm mode may follow a predictable data pattern. For example, the uplink data may include data packets that are the output of video coding. These data packets may follow a periodic pattern, may arrive periodically with a fixed size, and/or the like. For example, if the uplink data is a video stream encoded using a standard video codec (e.g., H. 264) , the uplink data may include intra-coded frames (I-frames) and predicted frames (P-frames) . The quantity, position, and/or size of I-frames and P-frames may be fixed according to a data pattern. The data pattern may depend on, for example, one or more video stream parameters such as a frame rate, a resolution, a quantization, and/or the like.

In some cases, a video stream transmitted by a UE 120 to a base station 110 may be encoded with low resolution (e.g., 240p, 480p, and/or the like) in a normal mode (e.g., a low throughput operating mode) , and may be encoded with high resolution (e.g., 720p, 1080p, and/or the like) in an alarm mode (e.g., a high throughput operating mode) . The UE 120 may transition from the normal mode to the alarm mode based at least in part on detecting a triggering event, such as motion detection in a video feed, detection of a suspicious person in a video feed, detection of a suspicious vehicle or object in a video feed, and/or the like.

Because the data pattern of the video stream in the alarm mode may be consistent, the UE 120 may signal the data pattern to the base station 110, and may then forego transmission of a BSR to indicate the size of data in a buffer of the UE 120. In this way, signaling overhead associated with transmission of the BSR and transmission of an uplink grant to schedule the BSR may be reduced or eliminated. Furthermore, UE resources (e.g., memory resources, processing resources, battery power, and/or the like) and base station resources (e.g., memory resources, processing resources, and/or the like) associated with processing the BSR and/or the uplink grant to schedule the BSR may be conserved. Furthermore, latency may be reduced by foregoing transmission of the BSR and the uplink grant that schedules the BSR, resulting in lower latency transmission of uplink data. Some techniques and apparatuses described herein permit the BSR and the uplink grant that schedules the BSR to be eliminated for uplink data with a known data pattern, thereby conserving network resources (by reducing signaling overhead) , conserving UE resources, conserving base station resources, and reducing latency.

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

Fig. 4 is a diagram illustrating an example 400 of configuring a scheduling request resource for an alarm mode of a UE, in accordance with various aspects of the present disclosure.

As shown in Fig. 4, a UE 120 and a base station 110 may communicate with one another. As shown by reference number 405, the UE 120 may transmit, to the base station 110, an indication of a data pattern for uplink data associated with a an alarm mode (e.g., a high throughput operating mode) of the UE 120. In some aspects, the UE 120 may transmit the indication in a radio resource control (RRC) message, such as an uplink (UL) information transfer message, a UE capability transfer message, and/or the like. The data pattern may include, for example, a size of the uplink data (e.g., a payload size, a size in bits or bytes, a size of one or more transport blocks (TBs) of the uplink data, and/or the like) , a periodicity of the uplink data (e.g., in time) , a duration of transmission of the uplink data (e.g., a length of time occupied by one or more uplink transmissions) , and/or the like. Additionally, or alternatively, the data pattern may indicate a size of a burst (e.g., a number of bits or bytes) , a number of bursts, and/or the like. The data pattern for the alarm mode may be associated with a higher data transfer rate, a larger data packet size, and/or the like as compared to a data pattern for a normal mode of the UE 120.

In some aspects, the data pattern may include a pattern (e.g., a first pattern) having a number of periodic and fixed size data packets (e.g., periodic data packets with a fixed size) . For example, the data pattern may indicate 30 frames per 0.5 seconds, with each frame having a size of about 100 kilobytes. In some aspects, the data pattern may include a pattern (e.g., a second pattern) having a number of periodic data packets that include a first (e.g., initial) packet having a first (e.g., larger) size and remaining packets having a second (e.g., smaller) size. As an example, a data pattern for 1080p resolution may include 30 frames per 0.5 seconds, with the first (e.g., initial) frame being an I-frame with a size of about 400 kilobytes and the remaining frames being P-frames with a size of about 40 kilobytes. As another example, a data pattern for 480p resolution may include 30 frames per 0.5 seconds, with the first (e.g., initial) frame being an I-frame with a size of about 100 kilobytes and the remaining frames being P-frames with a size of about 10 kilobytes. As another example, a data pattern for 240p resolution may include 30 frames per 0.5 seconds, with the first (e.g., initial) frame being an I-frame with a size of about 25 kilobytes and the remaining frames being P-frames with a size of about 2.5 kilobytes.

As shown by reference number 410, the base station 110 may transmit, to the UE 120, a configuration that indicates a scheduling request (SR) resource to be used for the alarm mode. The base station 110 may transmit the configuration to the UE 120 based at least in part on receiving the indication of the data pattern. In some aspects, the base station 110 may transmit the configuration in an RRC message. The SR resource may include, for example, a time resource, a frequency resource, a spatial resource (e.g., a beam) , a sequence, and/or the like. For example, the SR resource may include a sequence to be transmitted in a time-frequency resource. In some aspects, the SR resource configured for the alarm mode (sometimes referred to herein as a first SR resource) may be different from another SR resource configured for a normal mode (sometimes referred to herein as a second SR resource) , as described in more detail below in connection with Fig. 5. In some aspects, the first SR resource is the same as the second SR resource, and the base station 110 may activate or deactivate the (same) SR resource for the alarm mode or the normal mode, as described in more detail below in connection with Fig. 6.

As shown by reference number 415, the UE 120 may detect a triggering event for the alarm mode. The triggering event may be an event that causes the UE 120 to start transmitting uplink data at a higher data rate and/or with a larger packet size as compared to a normal mode. For example, the UE 120 may detect an alarm, may detect suspicious activity (e.g., in a video feed) , may detect motion in a video feed, may detect a suspicious person (e.g., in a video feed) , may detect a suspicious vehicle or object (e.g., in a video feed) , and/or the like. Such detection may be performed by one or more components of the UE 120, or may be performed by another device that notifies the UE 120. Although some aspects are described herein in connection with detecting a trigger event based at least in part on a video feed, other triggering events are contemplated, such as an audible trigger, an electronic trigger, a tactile trigger, and/or the like.

As shown by reference number 420, the UE 120 may transmit, to the base station 110, an SR in the SR resource configured for the alarm mode. In some aspects, the UE 120 may transmit the SR based at least in part on detecting the triggering event.

As shown by reference number 425, the base station 110 may transmit, to the UE 120, an uplink grant that indicates a set of uplink resources (e.g., PUSCH resources) to be used for the uplink data associated with the alarm mode. In some aspects, the base station 110 may transmit the uplink grant for the uplink data based at least in part on receiving the SR in the SR resource configured for the alarm mode.

As shown by reference number 430, the base station 110 may transmit the uplink grant for the uplink data in response to the SR without first transmitting an uplink grant for a BSR, and without receiving a BSR from the UE 120. Similarly, the UE 120 may receive the uplink grant for the uplink data in response to the SR without first receiving an uplink grant for a BSR, and without transmitting a BSR to the base station 110. Thus, the dynamic uplink resource assignment procedure for the alarm mode, as shown in Fig. 4, is a two-step procedure (e.g., transmission of an SR at 420 and transmission of an uplink grant for uplink data at 425) , while the dynamic uplink resource assignment procedure for the normal mode, as shown in Fig. 3, is a four-step procedure (e.g., transmission of an SR at 310, transmission of an uplink grant for the BSR at 315, transmission of the BSR at 320, and transmission of the uplink grant for the uplink data at 325) . Thus, as described above, some techniques and apparatuses described herein permit the BSR and the uplink grant that schedules the BSR to be eliminated for uplink data with a known data pattern, thereby conserving network resources (by reducing signaling overhead) , conserving UE resources, conserving base station resources, reducing latency, improving spectral efficiency, and permitting a larger number of UEs 120 to be supported by the base station 110. However, in some aspects, if the UE 120 has uplink data stored in the buffer other than the uplink data associated with the indicated data pattern, then the UE 120 may transmit a BSR in response to the uplink grant received from the base station 110, which may trigger the base station 110 to send an additional uplink grant based at least in part on the BSR.

As shown by reference number 435, the UE 120 may transmit, to the base station 110, the uplink data associated with the data pattern for the alarm mode. For example, the UE 120 may transmit the uplink data in the set of uplink resources received in the uplink grant from the base station 110 (e.g., described above in connection with reference number 425) . The UE 120 may transmit the uplink data according to the data pattern indicated to the base station (e.g., described above in connection with reference number 405) . In some aspects, the uplink data may include a video stream, such as data packets of a video stream, frames of a video stream (e.g., I-frames, P-frames, and/or the like) , and/or the like. When the UE 120 is operating in the alarm mode, the video stream may be encoded at a higher resolution than a video stream transmitted to the base station 110 while the UE 120 is operating in a normal mode.

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

Fig. 5 is a diagram illustrating an example 500 of configuring a scheduling request resource for an alarm mode of a UE, in accordance with various aspects of the present disclosure.

As described above in connection with Fig. 4, in some aspects, the SR resource configured for the alarm mode (sometimes referred to herein as a first SR resource) may be different from another SR resource configured for a normal mode (sometimes referred to herein as a second SR resource) . In this case, the base station 110 may configure the UE 120 with a first SR resource (e.g., for the alarm mode) and a second SR resource (e.g., for the normal mode) , as shown by reference number 505. In some aspects, the base station 110 may transmit a configuration for the first SR resource and the second SR resource in the same message, such as an RRC message. This configuration may be transmitted in a similar manner as described above in connection with reference number 410 of Fig. 4.

As shown by reference number 510, when the UE 120 is operating in the normal mode and has uplink data stored in a buffer of the UE 120, the UE 120 may transmit an SR in the second SR resource (e.g., the SR resource for the normal mode, shown as SR resource A) . As further shown, transmission of an SR in the second SR resource may trigger the base station 110 to transmit an uplink grant for a BSR. In this case, the UE 120 and the base station 110 may operate as described above in connection with Fig. 3 (e.g., using the four-step dynamic uplink resource assignment procedure) .

As shown by reference number 515, when the UE 120 is operating in the alarm mode and has uplink data stored in a buffer of the UE 120, the UE 120 may transmit an SR in the first SR resource (e.g., the SR resource for the alarm mode, shown as SR resource B) . As further shown, transmission of an SR in the first SR resource may trigger the base station 110 to transmit an uplink grant for uplink data according to the data pattern indicated by the UE 120 to the base station 110. In this case, the UE 120 and the base station 110 may operate as described above in connection with Fig. 4 (e.g., using the two-step dynamic uplink resource assignment procedure) . In some aspects, when operating in the alarm mode, the UE 120 may have low throughput data to be transmitted (e.g., low priority data) . In this case, the UE 120 may use the first SR resource to request uplink resources for transmission of high throughput data (e.g., a high resolution video feed) , and may use the second SR resource to request uplink resources for transmission of low throughput data.

Thus, as described above, some techniques and apparatuses described herein permit the BSR and the uplink grant that schedules the BSR to be eliminated for uplink data with a known data pattern, thereby conserving network resources (by reducing signaling overhead) , conserving UE resources, conserving base station resources, reducing latency, improving spectral efficiency, and permitting a larger number of UEs 120 to be supported by the base station 110.

As indicated above, Fig. 5 is provided as an example. Other examples may differ from what is described with regard to Fig. 5.

Fig. 6 is a diagram illustrating an example 600 of configuring a scheduling request resource for an alarm mode of a UE, in accordance with various aspects of the present disclosure.

As described above in connection with Fig. 4, in some aspects, the SR resource configured for the alarm mode (sometimes referred to herein as a first SR resource) may be the same as another SR resource configured for a normal mode (sometimes referred to herein as a second SR resource) . In this case, the base station 110 may configure the UE 120 with a single SR resource to be used for both the alarm mode and the normal mode, as shown by reference number 605. In some aspects, the base station 110 may transmit a configuration for the single SR resource in an RRC message. This configuration may be transmitted in a similar manner as described above in connection with reference number 410 of Fig. 4.

In this case, the UE 120 may indicate, to the base station 110, whether the UE 120 is operating in the normal mode or the alarm mode. The base station 110 may respond to an SR received in the SR resource based at least in part on the indication. For example, if the UE 120 is operating in the normal mode, then the base station 110 may transmit an uplink grant for a BSR upon receiving an SR in the SR resource. Conversely, if the UE 120 is operating in the alarm mode, then the base station 110 may transmit an uplink grant for uplink data with an indicated data pattern upon receiving an SR in the SR resource.

In some aspects, the UE 120 may operate in the normal mode by default (e.g., unless the UE 120 signals otherwise to the base station 110) . For example, as shown by reference number 610, after being configured with the SR resource, the UE 120 may transmit an SR in the SR resource. As shown by reference number 615, this SR may trigger the four-step dynamic resource allocation procedure described above in connection with Fig. 3 (e.g., with the BSR) .

As shown by reference number 620, the UE 120 may indicate, to the base station 110, that the UE 120 is operating in the alarm mode (e.g., a high throughput operating mode) . This indication may include an indication of a start of the data pattern indicated to the base station 110 as described above in connection with Fig. 4. As shown by reference number 625, in some aspects, the base station 110 may transmit an indication that the SR resource has been activated for the alarm mode (e.g., the high throughput operating mode) . In some aspects, this indication may include an acknowledgement (ACK) of the indication that the UE 120 is operating in the alarm mode. As shown by reference number 630, after transmitting the indication that the UE 120 is operating in the alarm mode and/or receiving the indication that the SR resource has been activated for the alarm mode, the UE 120 may transmit an SR in the SR resource. As shown by reference number 635, this SR may trigger the two-step dynamic resource allocation procedure described above in connection with Fig. 4 (e.g., without the BSR) .

As shown by reference number 640, the UE 120 may indicate, to the base station 110, that the UE 120 is operating in the normal mode (e.g., a non-alarm mode or a low throughput operating mode) . This indication may include an indication of an end of the data pattern indicated to the base station 110 as described above in connection with Fig. 4. As shown by reference number 645, in some aspects, the base station 110 may transmit an indication that the SR resource has been deactivated for the alarm mode (e.g., the high throughput operating mode) . In some aspects, this indication may include an ACK of the indication that the UE 120 is operating in the normal mode. As shown by reference number 650, after transmitting the indication that the UE 120 is operating in the normal mode and/or receiving the indication that the SR resource has been deactivated for the alarm mode, the UE 120 may transmit an SR in the SR resource. As shown by reference number 655, this SR may trigger the four-step dynamic resource allocation procedure described above in connection with Fig. 3 (e.g., with the BSR) .

Thus, as described above, some techniques and apparatuses described herein permit the BSR and the uplink grant that schedules the BSR to be eliminated for uplink data with a known data pattern, thereby conserving network resources (by reducing signaling overhead) , conserving UE resources, conserving base station resources, reducing latency, improving spectral efficiency, and permitting a larger number of UEs 120 to be supported by the base station 110. Furthermore, by using a single SR resource for both the alarm mode and the normal mode, fewer network resources need to be dedicated to SR resources.

As indicated above, Fig. 6 is provided as an example. Other examples may differ from what is described with regard to Fig. 6.

Fig. 7 is a diagram illustrating an example process 700 performed, for example, by a UE, in accordance with various aspects of the present disclosure. Example process 700 is an example where the UE (e.g., UE 120 and/or the like) performs operations associated with configuring a scheduling request resource for an alarm mode of a UE.

As shown in Fig. 7, in some aspects, process 700 may include transmitting, to a base station, an indication of a data pattern for uplink data associated with an alarm mode of the UE (block 710) . For example, the UE (e.g., using transmit processor 264, controller/processor 280, memory 282, and/or the like) may transmit, to a base station, an indication of a data pattern for uplink data associated with an alarm mode of the UE, as described above.

As further shown in Fig. 7, in some aspects, process 700 may include receiving, from the base station, a configuration that indicates a scheduling request resource to be used for the alarm mode based at least in part on transmitting the indication of the data pattern (block 720) . For example, the UE (e.g., using receive processor 258, controller/processor 280, memory 282, and/or the like) may receive, from the base station, a configuration that indicates a scheduling request resource to be used for the alarm mode based at least in part on transmitting the indication of the data pattern, as described above.

As further shown in Fig. 7, in some aspects, process 700 may include transmitting, to the base station, a scheduling request in the scheduling request resource (block 730) . For example, the UE (e.g., using transmit processor 264, controller/processor 280, memory 282, and/or the like) may transmit, to the base station, a scheduling request in the scheduling request resource, as described above.

As further shown in Fig. 7, in some aspects, process 700 may include receiving, from the base station and based at least in part on the scheduling request, an uplink grant that indicates a set of uplink resources to be used for the uplink data associated with the alarm mode (block 740) . For example, the UE (e.g., using receive processor 258, controller/processor 280, memory 282, and/or the like) may receive, from the base station and based at least in part on the scheduling request, an uplink grant that indicates a set of uplink resources to be used for the uplink data associated with the alarm mode, as described above.

Process 700 may include additional aspects, such as any single aspect or any combination of aspects described below and/or in connection with one or more other processes described elsewhere herein.

In a first aspect, process 700 includes transmitting, to the base station, the uplink data associated with the data pattern for the alarm mode in the set of uplink resources.

In a second aspect, alone or in combination with the first aspect, the uplink grant is received in response to the scheduling request without reception of an uplink grant for a buffer status report and without transmission of the buffer status report.

In a third aspect, alone or in combination with one or more of the first and second aspects, the scheduling request is transmitted based at least in part on detecting an event that triggers the alarm mode.

In a fourth aspect, alone or in combination with one or more of the first through third aspects, the indication of the data pattern indicates at least one of a data size of the uplink data, a periodicity of the uplink data, a duration of transmission of the uplink data, or a combination thereof.

In a fifth aspect, alone or in combination with one or more of the first through fourth aspects, the data pattern includes at least one of: a first pattern having a number of periodic and fixed size data packets, or a second pattern having a number of periodic data packets that include a first packet having a first size and remaining packets having a second size.

In a sixth aspect, alone or in combination with one or more of the first through fifth aspects, the uplink data associated with the alarm mode has at least one of a higher data transfer rate or a larger data packet size than a normal mode of the UE.

In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, the configuration further indicates another scheduling request resource, different from the scheduling request resource, to be used to trigger an uplink grant for a buffer status report.

In an eighth aspect, alone or in combination with one or more of the first through seventh aspects, transmission of a scheduling request in the scheduling request resource triggers: the uplink grant that indicates the set of uplink resources to be used for the uplink data when the UE is operating in the alarm mode, or an uplink grant for a buffer status report when the UE is operating in a normal mode.

In a ninth aspect, alone or in combination with one or more of the first through eighth aspects, process 700 includes indicating a start of the data pattern to the base station before transmitting the scheduling request in the scheduling request resource; receiving an indication that the scheduling request resource has been activated for the alarm mode; and transmitting the scheduling request in the scheduling request resource based at least in part on receiving the indication that the scheduling request resource has been activated, wherein transmission of the scheduling request triggers the uplink grant that indicates the set of uplink resources to be used for the uplink data associated with the alarm mode.

In a tenth aspect, alone or in combination with one or more of the first through ninth aspects, process 700 includes indicating an end of the data pattern to the base station after receiving the uplink grant that indicates the set of uplink resources to be used for the uplink data associated with the alarm mode; receiving an indication that the scheduling request resource has been deactivated for the alarm mode; and transmitting another scheduling request in the scheduling request resource based at least in part on receiving the indication that the scheduling request resource has been deactivated, wherein transmission of the other scheduling request triggers an uplink grant for a buffer status report.

In an eleventh aspect, alone or in combination with one or more of the first through tenth aspects, the uplink data is a video stream, and the alarm mode is triggered based at least in part on detecting a triggering event in the video stream.

Although Fig. 7 shows example blocks of process 700, in some aspects, process 700 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks than those depicted in Fig. 7. Additionally, or alternatively, two or more of the blocks of process 700 may be performed in parallel.

Fig. 8 is a diagram illustrating an example process 800 performed, for example, by a base station, in accordance with various aspects of the present disclosure. Example process 800 is an example where the base station (e.g., base station 110 and/or the like) performs operations associated with configuring a scheduling request resource for an alarm mode of a UE.

As shown in Fig. 8, in some aspects, process 800 may include receiving, from a UE, an indication of a data pattern for uplink data associated with an alarm mode of the UE (block 810) . For example, the base station (e.g., using receive processor 238, controller/processor 240, memory 242, and/or the like) may receive, from a UE, an indication of a data pattern for uplink data associated with an alarm mode of the UE, as described above.

As further shown in Fig. 8, in some aspects, process 800 may include transmitting, to the UE, a configuration that indicates a scheduling request resource to be used for the alarm mode based at least in part on receiving the indication of the data pattern (block 820) . For example, the base station (e.g., using transmit processor 220, controller/processor 240, memory 242, and/or the like) may transmit, to the UE, a configuration that indicates a scheduling request resource to be used for the alarm mode based at least in part on receiving the indication of the data pattern, as described above.

As further shown in Fig. 8, in some aspects, process 800 may include receiving, from the UE, a scheduling request in the scheduling request resource (block 830) . For example, the base station (e.g., using receive processor 238, controller/processor 240, memory 242, and/or the like) may receive, from the UE, a scheduling request in the scheduling request resource, as described above.

As further shown in Fig. 8, in some aspects, process 800 may include transmitting, to the UE and based at least in part on the scheduling request, an uplink grant that indicates a set of uplink resources to be used for the uplink data associated with the alarm mode (block 840) . For example, the base station (e.g., using transmit processor 220, controller/processor 240, memory 242, and/or the like) may transmit, to the UE and based at least in part on the scheduling request, an uplink grant that indicates a set of uplink resources to be used for the uplink data associated with the alarm mode, as described above.

Process 800 may include additional aspects, such as any single aspect or any combination of aspects described below and/or in connection with one or more other processes described elsewhere herein.

In a first aspect, process 800 includes receiving, from the UE, the uplink data associated with the data pattern for the alarm mode in the set of uplink resources.
