Description

BROADCAST PROTOCOL INDICATION

FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for transmitting and/or receiving broadcast protocol indications.

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, or the like) . Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, orthogonal frequency-division multiple access (OFDMA) systems, single-carrier frequency-division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE) . LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP) .

A wireless network may include a number of base stations (BSs) that can support communication for a number of user equipment (UEs) . A UE may communicate with a 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, 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. NR, which may also be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink (DL) , using CP-OFDM and/or SC-FDM (e.g., also known as discrete Fourier transform spread OFDM (DFT-s-OFDM) ) on the uplink (UL) , as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful.

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.

It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of a claim.

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

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

Fig. 1 is a diagram illustrating an example of a wireless network 100, in accordance with the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network and/or an LTE network, among other examples. The wireless network 100 may include a number of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with user equipment (UEs) and may also be referred to as an NR BS, a Node B, a gNB, a 5G node B (NB) , an access point, a transmit receive point (TRP) , 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 or a virtual network, using any suitable transport network.

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

Wireless network 100 may be a heterogeneous network that includes BSs of different types, such as macro BSs, pico BSs, femto BSs, relay BSs, 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, 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, and/or location tags, 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 and/or memory components. In some aspects, the processor components and the memory components may be coupled together. For example, the processor components (e.g., one or more processors) and the memory components (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.

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, or the like. A frequency may also be referred to as a carrier, a frequency channel, or the like. Each frequency may support a single RAT in a given geographic area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

In some 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 or a vehicle-to-infrastructure (V2I) protocol) , and/or a mesh network. In this case, the UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by the base station 110.

Devices of wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided based on frequency or wavelength into various classes, bands, channels, or the like. For example, devices of wireless network 100 may communicate using an operating band having a first frequency range (FR1) , which may span from 410 MHz to 7.125 GHz, and/or may communicate using an operating band having a second frequency range (FR2) , which may span from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is often referred to as a “sub-6 GHz” band. Similarly, FR2 is often referred to as a “millimeter wave” band despite being different from the extremely high frequency (EHF) band (30 GHz –300 GHz) which is identified by the International Telecommunications Union (ITU) as a “millimeter wave” band. Thus, unless specifically stated otherwise, it should be understood that the term “sub-6 GHz” or the like, if used herein, may broadly represent frequencies less than 6 GHz, frequencies within FR1, and/or mid-band frequencies (e.g., greater than 7.125 GHz) . Similarly, unless specifically stated otherwise, it should be understood that the term “millimeter wave” or the like, if used herein, may broadly represent frequencies within the EHF band, frequencies within FR2, and/or mid-band frequencies (e.g., less than 24.25 GHz) . It is contemplated that the frequencies included in FR1 and FR2 may be modified, and techniques described herein are applicable to those modified frequency ranges.

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

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

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

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

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

Antennas (e.g., antennas 234a through 234t and/or antennas 252a through 252r) may include, or may be included within, one or more antenna panels, antenna groups, sets of antenna elements, and/or antenna arrays, among other examples. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include a set of coplanar antenna elements and/or a set of non-coplanar antenna elements. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include antenna elements within a single housing and/or antenna elements within multiple housings. An antenna panel, an antenna group, a set of antenna elements, and/or an antenna array may include one or more antenna elements coupled to one or more transmission and/or reception components, such as one or more components of Fig. 2.

On the uplink, at UE 120, a transmit processor 264 may receive and process data from a data source 262 and control information (e.g., for reports that include RSRP, RSSI, RSRQ, and/or CQI) 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 or CP-OFDM) , and transmitted to base station 110. In some aspects, a modulator and a demodulator (e.g., MOD/DEMOD 254) of the UE 120 may be included in a modem of the UE 120. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of antenna (s) 252, modulators and/or demodulators 254, MIMO detector 256, receive processor 258, transmit processor 264, and/or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller/processor 280) and memory 282 to perform aspects of any of the methods described herein, for example, as described with reference to Figs. 3-5.

At base station 110, the uplink signals from UE 120 and other UEs may be received by antennas 234, processed by demodulators 232, detected by a MIMO detector 236 if applicable, and further processed by a receive processor 238 to obtain decoded data and control information sent by UE 120. Receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to controller/processor 240. Base station 110 may include communication unit 244 and communicate to network controller 130 via communication unit 244. Base station 110 may include a scheduler 246 to schedule UEs 120 for downlink and/or uplink communications. In some aspects, a modulator and a demodulator (e.g., MOD/DEMOD 232) of the base station 110 may be included in a modem of the base station 110. In some aspects, the base station 110 includes a transceiver. The transceiver may include any combination of antenna (s) 234, modulators and/or demodulators 232, MIMO detector 236, receive processor 238, transmit processor 220, and/or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller/processor 240) and memory 242 to perform aspects of any of the methods described herein, for example, as described with reference to Figs. 3-5.

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 transmitting and/or receiving broadcast protocol indications, 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 600 of Fig. 6, process 700 of Fig. 7, and/or other processes as described herein.

Memories

242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and/or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compiling, converting, and/or interpreting) by one or more processors of the base station 110 and/or the UE 120, may cause the one or more processors, the UE 120, and/or the base station 110 to perform or direct operations of, for example process 600 of Fig. 6, process 700 of Fig. 7, and/or other processes as described herein. In some aspects, executing instructions may include running the instructions, converting the instructions, compiling the instructions, and/or interpreting the instructions, among other examples.

In some aspects, the user equipment (UE) includes means for receiving an indication of a protocol, of a set of candidate protocols, associated with a broadcast communication; or means for receiving the broadcast communication based at least in part on the indication of the protocol. The means for the user equipment (UE) to perform operations described herein may include, for example, one or more of antenna 252, demodulator 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, modulator 254, controller/processor 280, or memory 282.

In some aspects, the base station includes means for transmitting an indication of a protocol, of a set of candidate protocols, associated with a broadcast communication; or means for transmitting the broadcast communication based at least in part on the protocol. The means for the base station to perform operations described herein may include, for example, one or more of transmit processor 220, TX MIMO processor 230, modulator 232, antenna 234, demodulator 232, MIMO detector 236, receive processor 238, controller/processor 240, memory 242, or scheduler 246.

While blocks in Fig. 2 are illustrated as distinct components, the functions described above with respect to the blocks may be implemented in a single hardware, software, or combination component or in various combinations of components. For example, the functions described with respect to the transmit processor 264, the receive processor 258, and/or the TX MIMO processor 266 may be performed by or under the control of controller/processor 280.

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

Some wireless networks may provide unicast sessions, multicast sessions, and/or broadcast sessions for a UE to receive communications from a user plane function (UPF) device. In the case of broadcast sessions, a base station may transmit information for a UE to use for reception of subsequent broadcast communications. For example, the base station may transmit information associated with a supported protocol. The base station may support, for broadcast sessions, real-time object delivery over unidirectional transport (ROUTE) protocol, motion picture experts group (MPEG) media transport (MMT) protocol, or file delivery over unidirectional transport (FLUTE) . Each of these protocols may be associated with different configurations for receiving broadcast messages. For example, FLUTE protocol may be configured for general data transmission and not for low-latency transmission, and ROUTE may be configured for low-latency transmissions and not for high throughput transmission.

In this way, the base station may be configured with a protocol for general data transmission or with a protocol for low-latency transmission, which may be optimal for some connected UEs and suboptimal for other connected UEs. For example, a base station that supports ROUTE may have a relatively low spectral efficiency in broadcast communications, based at least in part on, for example, an increased amount of overhead used to support low-latency transmissions.

In some aspects described herein, a base station may support multiple protocols (e.g., smart media transport (SMT) , ROUTE, and/or FLUTE, among other examples) . For example, an application interface block (AIB) of a conceptional protocol stack may support the multiple protocols. In some aspects, the base station may transmit an indication of support for the multiple protocols (e.g., a set of candidate protocols) and/or an indication of a protocol associated with a broadcast communication. For example, the base station may transmit the indication of the protocol associated with the broadcast communication within a service announcement. In some aspects, the base station may transmit the indication (e.g., an indication of support of ROUTE and/or FLUTE) of the protocol associated with the broadcast communication within a service description protocol (SDP) of the service announcement. For example, in some aspects, the base station may transmit the indication (e.g., an indication of support for SMT) via stage 3 signaling at the service announcement.

Based at least in part on the base station supporting multiple protocols and transmitting an indication of a protocol associated with a broadcast communication, the base station may transmit broadcast communications with a protocol that is efficient for the broadcast communications, and a receiving UE may receive the broadcast communication based at least in part on the indication of the protocol. In this way, the base station may improve spectral efficiency for broadcast communications, improve latency for low-latency communications, and/or allow the base station to support types of broadcast communication that may not be supportable.

Fig. 3 is a diagram illustrating an example 300 associated with transmitting and/or receiving broadcast protocol indications, in accordance with the present disclosure. As shown in Fig. 3, a UE (e.g., UE 120) may communicate with a base station (e.g., base station 110) . The UE and the base station may be part of a wireless network (e.g., wireless network 100) . The UE and the base station may be configured to communicate via one or more broadcast protocols, with the base station transmitting broadcast communications and the UE receiving the broadcast communications.

As shown by reference number 305, the UE may receive configuration information (e.g., from the base station, another base station, and/or the like) and/or may determine the configuration information based at least in part on a communication protocol. In some aspects, the UE may receive the configuration information via one or more of radio resource control (RRC) signaling, MAC control elements (MAC CEs) , downlink control information (DCI) , and/or the like. In some aspects, the configuration information may include an indication of one or more configuration parameters (e.g., already known to the UE) for selection by the UE, and/or explicit configuration information for the UE to use to configure the UE, among other examples.

In some aspects, the configuration information may indicate that the UE is to receive an indication of a protocol associated with a broadcast communication. In some aspects, the configuration information may indicate a location of the indication of the protocol within signaling from the base station. For example, the configuration information may indicate that the indication of the protocol is within a service announcement. In some aspects, the configuration information may indicate a set of candidate protocols from which the protocol may be selected. In some aspects, the configuration information may indicate that the UE is to receive an indication of a configuration of a broadcast session associated with a broadcast communication and/or an indication of a configuration associated with a media source associated with the broadcast communication. In some aspects, the configuration information may indicate that the UE is to decode the broadcast communication based at least in part on the protocol and/or the configuration associated with the broadcast session and/or the media type.

As shown by reference number 310, the UE may configure the UE for communicating with the base station. In some aspects, the UE may configure the UE based at least in part on the configuration information. In some aspects, the UE may be configured to perform one or more operations described herein.

As shown by reference number 315, the UE may receive, and the base station may transmit, an indication of a protocol associated with a broadcast communication. In some aspects, the UE may receive the indication of the protocol within a service announcement. In some aspects, the service announcement may include the indication of the protocol within a session description protocol (SDP) field (e.g., an SDP media field) . The SDP field may indicate a protocol type and/or a profile name within the protocol type and associated with the downlink communication.

The indication of the protocol (e.g., within a field of the service announcement) may use a number of bits to indicate the protocol from a set of candidate protocols. In some aspects, the UE may receive the indication may indicate a selection of the protocol from a set of candidate protocols. For example, the indication may indicate that a broadcast communication is associated with (e.g., is to be transmitted based at least in part) a protocol selected from FLUTE, MMT, ROUTE, or SMT, among other examples.

As shown by reference number 320, the UE may receive, and the base station may transmit, an indication of a configuration associated with the broadcast communication. In some aspects, the configuration may be associated with a broadcast session and/or associated with a media source associated with the broadcast communication. In some aspects, the configuration indicates whether the broadcast communication is a real time broadcast communication. In some aspects, the configuration information indicates an encoding applied to the broadcast communication.

In some aspects, the indication of the configuration may apply to all broadcast communications of a broadcast session. In this way, the UE does not need to search each occasion of the service announcement for a protocol to use for reception of subsequent broadcast communications when connected to the broadcast session. In some aspects, the indication of the configuration may apply to all broadcast communications associated with (e.g., coming from) a media source, such as a user plane function device, an application, and/or an application type, among other examples. In this way, the UE does not need to search each occasion of the service announcement for a protocol to use for reception of subsequent broadcast communications when receiving a broadcast communication that is associated with a same media source.

As shown by reference number 325, the UE may receive, and the base station may transmit, the broadcast communication. For example, the UE may receive the broadcast communication based at least in part on the protocol, the indication of the protocol, the configuration associated with the broadcast session, the configuration associated with the media source, or another indication of a configuration associated with the broadcast communication, among other examples. In some aspects, the UE may receive the broadcast communication based at least in part on the detecting session level signaling of the broadcast session associated with the broadcast communication. For example, the UE may use a configuration (e.g., as indicated in connection with reference number 320) to detect the session level signaling.

As shown by reference number 330, the UE may decode the broadcast communication based at least in part on the protocol. In some aspects, the UE may decode the broadcast communication based at least in part on determining a configuration associated with the protocol. For example, based at least in part on receiving the indication of the protocol, the UE may receive the indication of the configuration. Based at least in part on the indication of the configuration, the UE may apply a decoding scheme to the broadcast communication to decode data of the broadcast communication.

Based at least in part on the base station supporting multiple protocols and transmitting an indication of a protocol associated with a broadcast communication, the base station may indicate to the UE to use a protocol that is efficient for the broadcast communications to receive the broadcast communication. In this way, the base station may improve spectral efficiency for broadcast communications, improve latency for low-latency communications, and/or allow the base station to support types of broadcast communication that may not be supportable.

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 associated with transmitting and/or receiving broadcast protocol indications, in accordance with the present disclosure.

A first layer of the protocol stack may include an application layer 405 (e.g., an AIB layer) that supports multiple protocols (e.g., FLUTE, ROUTE, and/or SMT, among other examples) . In some aspects, the application layer 405 may interface with one or more UPF devices to receive media for transmission via broadcast sessions.

A second layer of the protocol stack may include medium resources 410A and/or 410B. For example, medium resource 410A may be a real time medium resource, and medium resource 410B may be a non-real time medium resource. The second layer may also include a first protocol signaling resource 415A (e.g., associated with SMT) and a second protocol signaling resource 415B (e.g., associated with FLUTE and/or ROUTE) . In some aspects, the first protocol signaling resource 415A and the second protocol signaling resource 415B may be used to indicate a configuration associated with a broadcast communication (e.g., as described in connection with reference number 320) that is transmitted using the first protocol or the second protocol, respectively.

A service announcement resource 420 may also be included in the second layer of the protocol stack. The service announcement may indicate other information in the second layer of the protocol stack, or other layers of the protocol stack, that are relevant to a UE. For example, based at least in part on the service announcement indicating that the first protocol is to be used for broadcast communications that the UE intends to receive, the UE may receive the first protocol signaling resource 415A and ignore the second protocol signaling resource 415B. In some aspects, the UE may be configured to receive the service announcement 420 before attempting to receive other resources of the second layer, or lower layers, of the protocol stack.

In some aspects, the protocol stack may include a files resource 425 that include media, such as common media application format (CMAF) low-latency (CMAF-LL) , Dynamic Adaptive Streaming over HTTP (DASH) , and/or HTTP live streaming (HLS) .

In some aspects, the FEC code resource 440 or the FEC code resource may be associated with a third protocol based at least in part on, for example, an indication (e.g., within the service announcement) that the third protocol is to be used instead of the first protocol or the second protocol. The third layer of the protocol stack may include an HTTP, HTTP, or other unicast transfer protocol resource 450 associated an indication of a routing procedure for, a target device of, and/or a source of, unicast data.

A fourth layer of the protocol stack may include a user datagram protocol (UDP) resource 455 as a transport layer for multicast and/or broadcast communications. The fourth layer may also include a UDP resource 460 as a transport layer for unicast communications.

As indicated above, Fig. 4 is provided as an example. Other examples may differ from what is described with regard to Fig. 4. For example, one or more additional resources may be added to the described protocol stack, one or more resources may be moved to other layers of the protocol stack, and/or one or more resources may be removed from the protocol stack.

The UE and the base station may be part of a wireless network (e.g., wireless network 100) .

A second layer of the protocol stack may include a service announcement 510, a protocol signaling resource 515 and a files resource 520. Additional resources of the second layer of the protocol stack may be associated with unicast communications, such as an associated delivery procedures resource 525 or a file repair and reception report resource 530.

A third layer of the protocol stack may include a forward error correction (FEC) code resource 440 a selected protocol. The third layer of the protocol stack may include an HTTP, HTTP, or other unicast transfer protocol resource 535.

A fourth layer of the protocol stack may include a UDP resource 540 as a transport layer for multicast and/or broadcast communications. The fourth layer may also include a UDP resource 545 as a transport layer for unicast communications.

A fifth layer of the protocol stack may include an IP layer resource 550 associated with multicast communications. The fifth layer may also include an IP layer resource 555 associated with unicast communications.
