AI Technical Summary
When existing wireless communication systems perform multicast service scheduling across multiple radio access technologies (RATs), it is difficult to effectively prioritize delay-sensitive multicast services, resulting in poor user experience and inability to meet the requirements.
After receiving the multicast data in the first RAT (such as a 5G network), the relevant multicast service parameters are passed to the scheduler of the second RAT (such as a Wi-Fi network), and the transmission of the multicast data is prioritized. The scheduler can prioritize based on multicast service parameters, such as the number of clients, service quality, bandwidth, client capabilities, other data flows and feedback solutions to receive multicast communication.
It realizes effective priority processing of delay-sensitive multicast services, improves user experience, ensures the quality goals of multicast services, and enhances the reliability and efficiency of the network.

[0002] This patent application claims priority to U.S. patent application No. 17 / 942,973, entitled “MULTICASTTRAFFIC SCHEDULING ACROSS MULTIPLE RADIO ACCESS TECHNOLOGIES,” filed by Babbellapati et al. on September 12, 2022, which is assigned to the assignee of this application and is expressly incorporated herein by reference. Technical Field
[0003] The following relates to wireless communications, including multicast traffic scheduling across multiple radio access technologies. Background Art
[0004] Wireless communication systems are widely deployed to provide various types of communication content, such as voice, video, packet data, messaging, broadcast, etc. These systems may be able to support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include fourth generation (4G) systems (such as long term evolution (LTE) systems, advanced LTE (LTE-A) systems, or LTE-A Pro systems) and fifth generation (5G) systems (which may be referred to as new radio (NR) systems). These systems may employ techniques such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple access communication system may include one or more base stations, each of which supports wireless communications for communication devices, which may be referred to as user equipment (UE).
[0005] In some deployments, a UE may be capable of using two or more radio access technologies (RATs) for radio communications. For example, a UE may be capable of wireless communications using a wide area network (WAN) such as a 4G or 5G wireless communication system and a wireless local area network (WLAN) such as a Wi-Fi (i.e., Institute of Electrical and Electronics Engineers (IEEE) 802.11) network. In some cases, multiple networks may be used to send communications, such as communications originating from a WAN and contending using a WLAN. Efficient techniques for communicating across multiple RATs may help improve throughput, reliability, and user experience. Summary of the invention

[0033] In some wireless communication systems, a fixed wireless access (FWA) deployment may be used, where a wireless device (e.g., a Wi-Fi access point (AP)) of a wireless local area network may carry the last leg of traffic between a wide area network (e.g., a fifth generation (5G) or sixth generation (6G) wireless communication system) and one or more endpoint devices (e.g., user equipment (UE) or end-user devices). In some cases, a wide area network (WAN) may send multicast and broadcast service (MBS) traffic to multiple users, some of which may receive the MBS traffic via a wireless local area network (WLAN) that receives the traffic from the WAN and provides it to associated users. For example, a Wi-Fi AP may communicate with a 5G modem (e.g., in a customer premises equipment (CPE) that includes both a 5G modem and a WLAN AP), where the 5G modem receives the MBS traffic via a 5G network (e.g., a first radio access network (RAN) using a first RAT), and the AP completes the link to the multiple users using a Wi-Fi connection (e.g., a second RAN using a second RAT). In some cases, the 5G modem may have relatively good channel conditions and radio connectivity to the 5G network, and the network may operate based on such conditions (e.g., data rates are based on relatively good channel conditions between the 5G modem and the 5G serving cell).
[0034] However, in some cases, the WLAN may serve multiple different flows, which may result in a bottleneck for the MBS traffic, which may result in delays for the MBS traffic and a poor user experience in situations where the MBS traffic is delay sensitive. For example, such a bottleneck may occur because a scheduler at the WLAN (e.g., a scheduler of a Wi-Fi AP) is unaware that the MBS traffic is delay sensitive and serves other services that are more delay tolerant (e.g., enhanced mobile broadband (eMBB) traffic, or other background (BK) or best effort (BE) traffic) before the MBS traffic. In situations where the MBS traffic experiences such delays, it may result in the MBS traffic not meeting quality of service (QoS) targets even if the 5G network has information indicating relatively good channel conditions at the 5G modem. Therefore, an enhanced technique that allows the LAN to use a second RAN (e.g., a Wi-Fi network) to provide appropriate prioritization of connectivity for the "last mile" between the first RAN and the UE for the MBS traffic of the first RAN (e.g., a 5G network) may help enhance the user experience, maintain the MBS QoS targets, and enhance reliability and network efficiency.
[0035] According to various aspects discussed herein, a WAN modem (e.g., a 5G modem providing connectivity to a 5G network) may provide MBS information related to MBS traffic carried to one or more end users via the WAN and the LAN to a LAN scheduler (e.g., a Wi-Fi scheduler of a Wi-Fi AP). Information related to the MBS traffic may be passed from the WAN modem to the LAN scheduler together with or separately from the MBS data. In some cases, the MBS information may be used to provide prioritization at the LAN scheduler. In some cases, the LAN scheduler may prioritize traffic communications via the LAN based on any combination of: the number of clients, QoS parameters (e.g., 5QI parameters and associated thresholds provided with some 5G communications), bandwidth of the traffic (e.g., whether the bandwidth is above or below a threshold), LAN client capabilities (e.g., capabilities of Wi-Fi devices such as stations (STAs) or user equipment (UEs) for multiple access communications such as OFDMA / MU-MIMO), the presence of non-MBS streams, feedback techniques for MBS data (e.g., communications not configured for ACK / NACK feedback may have lower QoS targets relative to communications using only NACK or ACK / NACK feedback). The LAN scheduler may receive MBS information and prioritize MBS traffic over other more delay-tolerant traffic (e.g., BK or BE traffic), which may enhance efficiency and provide MBS service with appropriate quality. In some cases, the LAN scheduler may place MBS data in an access category (AC) queue based on the MBS information. Additionally or alternatively, the LAN scheduler may implement a separate AC transmit queue for low-latency traffic based on MBS information.
[0036] Various aspects of the present disclosure are first described in the context of a wireless communication system. Various aspects of the present disclosure are further illustrated by and described with reference to process flows, AC queues, device diagrams, system diagrams, and flow charts involving multicast service scheduling across multiple RATs.
[0037] Figure 1 An example of a wireless communication system 100 supporting multicast service scheduling across multiple RATs according to one or more aspects of the present disclosure is illustrated. The wireless communication system 100 may include one or more network entities 105, one or more UEs 115, and a core network 130. In some examples, the wireless communication system 100 may be a long term evolution (LTE) network, an advanced LTE (LTE-A) network, an LTE-A Pro network, a new radio (NR) network, or a network operating according to other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0038] The network entities 105 may be dispersed throughout a geographic area to form the wireless communication system 100, and may include devices in different forms or with different capabilities. In various examples, the network entities 105 may be referred to as network elements, mobility elements, radio access network (RAN) nodes, or network equipment, among other nomenclature. In some examples, the network entities 105 and the UE 115 may communicate wirelessly via one or more communication links 125 (e.g., radio frequency (RF) access links). For example, the network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) within which the UE 115 and the network entity 105 may establish one or more communication links 125. The coverage area 110 may be an example of a geographic area within which the network entity 105 and the UE 115 may support signal communications according to one or more RATs.
[0039] The UEs 115 may be dispersed throughout the coverage area 110 of the wireless communication system 100, and each UE 115 may be stationary or mobile, or stationary and mobile at different times. The UEs 115 may be devices in different forms or with different capabilities. Figure 1 Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communication with various types of devices, such as Figure 1 Communicate with other UEs 115 or network entities 105) as shown.
[0040] As described herein, a node of the wireless communication system 100 (which may be referred to as a network node or a wireless node) may be a network entity 105 (e.g., any network entity described herein), a UE 115 (e.g., any UE described herein), a network controller, an apparatus, a device, an endpoint device, a CPE, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, the node may be a UE 115. As another example, the node may be a network entity 105 or a CPE 185. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105 or a CPE 185, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105 or a CPE 185, and the third node may be a network entity 105 or a CPE 185. In other aspects of this example, the first node, the second node, and the third node may be different relative to these examples. Similarly, references to UE 115, network entity 105, CPE 185, devices, equipment, computing systems, etc. may include disclosure of UE 115, network entity 105, CPE 185, devices, equipment, computing systems, etc. as nodes. For example, a disclosure that UE 115 is configured to receive information from network entity 105 also discloses that the first node is configured to receive information from a second node.
[0041] In some examples, the network entities 105 may communicate with the core network 130, or with each other, or both. For example, the network entities 105 may communicate with the core network 130 via one or more backhaul communication links 120 (e.g., according to S1, N2, N3, or other interface protocols). In some examples, the network entities 105 may communicate with each other directly (e.g., directly between the network entities 105) or indirectly (e.g., via the core network 130) via the backhaul communication links 120 (e.g., according to X2, Xn, or other interface protocols). In some examples, the network entities 105 may communicate with each other via midhaul communication links 162 (e.g., according to a midhaul interface protocol) or fronthaul communication links 168 (e.g., according to a fronthaul interface protocol) or any combination thereof. The backhaul communication links 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., electrical links, optical fiber links), one or more wireless links (e.g., radio links, wireless optical links), etc. or various combinations thereof. UE 115 may communicate with core network 130 via communication link 155 .
[0042] One or more of the network entities 105 described herein may include or may be referred to as a base station 140 (e.g., a transceiver base station, a radio base station, an NR base station, an access point, a radio transceiver, a Node B, an evolved Node B (eNB), a next generation Node B, or a Gigabit Node B (any of which may be referred to as a gNB), a 5G NB, a next generation eNB (ng-eNB), a home Node B, a home evolved Node B, or other suitable terms). In some examples, the network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, stand-alone) base station architecture, which may be configured to utilize a protocol stack physically or logically integrated within a single network entity 105 (e.g., a single RAN node, such as a base station 140).
[0043] In some examples, the network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) that may be configured to utilize a protocol stack that is physically or logically distributed between two or more network entities 105, such as an integrated access backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance), or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN)). For example, the network entity 105 may include one or more of the following: a central unit (CU) 160, a distributed unit (DU) 165, a radio unit (RU) 170, a RAN intelligent controller (RIC) 175 (e.g., a near real-time RIC (near RT RIC), a non-real-time RIC (non-RT RIC)), a service management and orchestration (SMO) 180 system, or any combination thereof. The RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH), a remote radio unit (RRU), or a transmit receive point (TRP). One or more components of the network entity 105 in the decomposed RAN architecture may be co-located, or one or more components of the network entity 105 may be located in distributed locations (e.g., separate physical locations). In some examples, one or more network entities 105 of the decomposed RAN architecture may be implemented as virtual units (e.g., virtual CU (VCU), virtual DU (VDU), virtual RU (VRU)).
[0044] The functional split between CU 160, DU 165, and RU 170 is flexible and may support different functionalities, depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, and any combination thereof) are performed at CU 160, DU 165, or RU 170. For example, a functional split of a protocol stack may be employed between CU 160 and DU 165 such that CU 160 may support one or more layers of a protocol stack and DU 165 may support one or more different layers of a protocol stack. In some examples, CU 160 may host higher protocol layer (e.g., layer 3 (L3), layer 2 (L2)) functionality and signaling (e.g., radio resource control (RRC), service data adaptation protocol (SDAP), packet data convergence protocol (PDCP)). The CU 160 may be connected to one or more DUs 165 or RUs 170, and the one or more DUs 165 or RUs 170 may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally or alternatively, a functional split of the protocol stack may be employed between the DU 165 and the RU 170, such that the DU 165 may support one or more layers of the protocol stack, and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or more different cells (e.g., via one or more RUs 170). In some cases, the functional split between CU 160 and DU 165 or between DU 165 and RU 170 can be within the protocol layer (e.g., some functions of the protocol layer can be performed by one of CU 160, DU 165, or RU 170, while other functions of the protocol layer are performed by different ones of CU 160, DU 165, or RU 170). CU 160 can be further functionally split into CU control plane (CU-CP) and CU user plane (CU-UP) functions. CU 160 can be connected to one or more DUs 165 via midhaul communication links 162 (e.g., F1, F1-c, F1-u), and DU 165 can be connected to one or more RUs 170 via fronthaul communication links 168 (e.g., open fronthaul (FH) interface). In some examples, midhaul communication link 162 or fronthaul communication link 168 may be implemented based on interfaces (eg, channels) between layers of a protocol stack supported by respective network entities 105 that communicate via those communication links.
[0045] In some wireless communication systems (e.g., wireless communication system 100), infrastructure and spectrum resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, thereby providing an IAB network architecture (e.g., to core network 130). In some cases, in an IAB network, one or more network entities 105 (e.g., IAB nodes 104) may be partially controlled by each other. One or more IAB nodes 104 may be referred to as donor entities or IAB donors. One or more DUs 165 or one or more RUs 170 may be controlled in part by one or more CUs 160 associated with a donor network entity 105 (e.g., donor base station 140). One or more donor network entities 105 (e.g., IAB donors) may communicate with one or more additional network entities 105 (e.g., IAB nodes 104) via supported access and backhaul links (e.g., backhaul communication links 120). The IAB node 104 may include an IAB mobile terminal (IAB-MT) controlled (e.g., scheduled) by a coupled IAB donor's DU 165. The IAB-MT may include an independent set of antennas for relaying communications with the UE 115, or may share the same antennas of the IAB node 104 (e.g., of the RU 170) for access via the DU 165 of the IAB node 104 (e.g., referred to as a virtual IAB-MT (vIAB-MT)). In some examples, the IAB node 104 may include a DU 165 that supports communication links with additional entities (e.g., IAB node 104, UE 115) within a relay chain or configuration (e.g., downstream) of the access network. In such cases, one or more components of the decomposed RAN architecture (e.g., one or more IAB nodes 104 or components of the IAB node 104) may be configured to operate according to the techniques described herein.
[0046] For example, an access network (AN) or RAN may include an access node (e.g., an IAB donor), communications between an IAB node 104, and one or more UEs 115. The IAB donor may facilitate connectivity between the core network 130 and the AN (e.g., via a wired or wireless connection to the core network 130). That is, the IAB donor may refer to a RAN node having a wired or wireless connection to the core network 130. The IAB donor may include a CU 160 and at least one DU 165 (e.g., and RU 170), in which case the CU 160 may communicate with the core network 130 via an interface (e.g., a backhaul link). The IAB donor and the IAB node 104 may communicate via an F1 interface according to a protocol defining signaling messages (e.g., an F1AP protocol). Additionally or alternatively, CU 160 may communicate with the core network via an interface (which may be an example of a portion of a backhaul link) and may communicate with other CUs 160 (e.g., CUs 160 associated with alternative IAB donors) via an Xn-C interface (which may be an example of a portion of a backhaul link).
[0047] The IAB node 104 may refer to a RAN node that provides IAB functions (e.g., access for UE 115, wireless self-backhaul capabilities, etc.). The DU 165 may act as a distributed scheduling node toward a child node associated with the IAB node 104, and the IAB-MT may act as a scheduled node toward a parent node associated with the IAB node 104. That is, the IAB donor may be referred to as a parent node that communicates with one or more child nodes (e.g., the IAB donor may relay the UE's transmission through one or more other IAB nodes 104). Additionally or alternatively, the IAB node 104 may also be referred to as a parent node or child node of other IAB nodes 104, depending on the relay chain or configuration of the AN. Therefore, the IAB-MT entity of the IAB node 104 may provide a Uu interface for the child IAB node 104 to receive signaling from the parent IAB node 104, and the DU interface (e.g., DU 165) may provide a Uu interface for the parent IAB node 104 to signal to the child IAB node 104 or the UE 115.
[0048] For example, the IAB node 104 may be referred to as a parent node supporting communications for a child IAB node or as a child IAB node associated with an IAB donor, or both. The IAB donor may include a CU 160 having a wired or wireless connection (e.g., backhaul communication link 120) to the core network 130, and may act as a parent node of the IAB node 104. For example, the DU 165 of the IAB donor may relay the transmission to the UE 115 through the IAB node 104, or may directly signal the transmission to the UE 115, or both. The CU 160 of the IAB donor may signal the IAB node 104 via the F1 interface that the communication link is established, and the IAB node 104 may schedule the transmission (e.g., the transmission relayed from the IAB donor to the UE 115) through the DU 165. That is, data may be relayed to and from the IAB node 104 via the NR Uu interface of the MT to the IAB node 104 via signaling. Communications with the IAB node 104 may be scheduled by the DU 165 of the IAB donor, and communications with the IAB node 104 may be scheduled by the DU 165 of the IAB node 104 .
[0049] In the case where the techniques described herein are applied to the context of a decomposed RAN architecture, one or more components of the decomposed RAN architecture may be configured to support multicast service scheduling across multiple RATs as described herein. For example, some operations described as being performed by UE 115 or network entity 105 (e.g., base station 140) may be additionally or alternatively performed by one or more components of the decomposed RAN architecture (e.g., IAB node 104, DU 165, CU 160, RU 170, RIC 175, SMO 180).
[0050] UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, and an endpoint device, or a subscriber device, or some other suitable term, where a "device" may also be referred to as a unit, a station, a terminal, or a client, etc. In some cases, UE 115 may also act as a CPE. UE 115 may also include or may be referred to as a personal electronic device, such as a cellular phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, UE 115 may include or may be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communication (MTC) device, etc., which may be implemented in various objects such as electrical appliances or vehicles, meters, etc.
[0051] The UE 115 described herein may be capable of communicating with various types of devices such as other UEs 115 which may sometimes act as relays, as well as network entities 105 and network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, etc. Figure 1 shown.
[0052] The UE 115 and the network entity 105 may wirelessly communicate with each other via one or more communication links 125 (e.g., access links) using resources associated with one or more carriers. The term "carrier" may refer to a collection of RF spectrum resources having a physical layer structure defined for supporting the communication link 125. For example, a carrier for the communication link 125 may include a portion of an RF spectrum band (e.g., a bandwidth portion (BWP)) that operates according to one or more physical layer channels for a given radio access technology (e.g., LTE, LTE-A, LTE-A Pro, NR). Each physical layer channel may carry acquisition signaling (e.g., synchronization signals, system information), control signaling for coordinating carrier operations, user data, or other signaling. The wireless communication system 100 may support communications with the UE 115 using carrier aggregation or multi-carrier operation. Depending on the carrier aggregation configuration, the UE 115 may be configured to have multiple downlink component carriers and one or more uplink component carriers. Carrier aggregation may be used for both frequency division duplex (FDD) and time division duplex (TDD) component carriers. Communication between the network entity 105 and other devices may refer to communication between these devices and any portion (e.g., entity, sub-entity) of the network entity 105. For example, the terms "send," "receive," or "communicate" when referring to the network entity 105 may refer to any portion of a network entity 105 (e.g., base station 140, CU 160, DU 165, RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities 105).
[0053] In some examples, such as in a carrier aggregation configuration, a carrier may also have acquisition signaling or control signaling that coordinates the operation of other carriers. A carrier may be associated with a frequency channel (e.g., an Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA) Absolute RF Channel Number (EARFCN)) and may be identified based on a channel raster for discovery by UE 115. A carrier may operate in a standalone mode, in which case initial acquisition and connection may be made by UE 115 via the carrier, or a carrier may operate in a non-standalone mode, in which case a different carrier (e.g., of the same or different RAT) is used to anchor the connection.
[0054] The communication link 125 shown in the wireless communication system 100 may include downlink transmissions (e.g., forward link transmissions) from the network entity 105 to the UE 115, uplink transmissions (e.g., return link transmissions) from the UE 115 to the network entity 105, or both, as well as other transmission configurations. A carrier may carry downlink communications or uplink communications (e.g., in FDD mode), or may be configured to carry downlink communications and uplink communications (e.g., in TDD mode).
[0055] The signal waveform transmitted via the carrier may include multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques, such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM)). In a system using MCM techniques, a resource element may refer to a resource of one symbol period (e.g., the duration of one modulation symbol) and one subcarrier, in which case the symbol period and the subcarrier spacing may be inversely related. The number of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both), so that a relatively high number of resource elements (e.g., in the transmission duration) and a relatively high order modulation scheme may correspond to a relatively high communication rate. Wireless communication resources may refer to a combination of RF spectrum resources, time resources, and spatial resources (e.g., spatial layers or beams), and the use of multiple spatial resources may increase the data rate or data integrity used for communication with UE 115.
[0056] The time interval for the network entity 105 or the UE 115 may be expressed in multiples of a basic time unit, which may be, for example, a sampling period T s =1 / (Δf max ·N f ) seconds, where Δf max It can represent the supported subcarrier spacing, and N f The supported discrete Fourier transform (DFT) size may be indicated. The time intervals of the communication resources may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms)). Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023).
[0057] Each frame may include multiple consecutively numbered subframes or time slots, and each subframe or time slot may have the same duration. In some examples, the frame may be divided into subframes (e.g., in the time domain), and each subframe may be further divided into a certain number of time slots. Alternatively, each frame may include a variable number of time slots, and the number of time slots may depend on the subcarrier spacing. Each time slot may include a certain number of symbol periods (e.g., depending on the length of the cyclic prefix appended in front of each symbol period). In some wireless communication systems 100, the time slot may be further divided into a plurality of micro time slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., N f The duration of a symbol period may depend on the subcarrier spacing or the operating frequency band.
[0058] A subframe, a time slot, a mini-time slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In some examples, the TTI duration (e.g., the number of symbol periods in a TTI) may be variable. Additionally or alternatively, the smallest scheduling unit of the wireless communication system 100 may be dynamically selected (e.g., in a burst of a shortened TTI (sTTI)).
[0059] Physical channels may be multiplexed according to various techniques in order to communicate using a carrier. For example, physical control channels and physical data channels may be multiplexed using one or more of a time division multiplexing (TDM) technique, a frequency division multiplexing (FDM) technique, or a hybrid TDM-FDM technique to signal via a downlink carrier. A control region (e.g., a control resource set (CORESET)) of a physical control channel may be defined by a set of symbol periods and may extend across a system bandwidth of a carrier or a subset of that system bandwidth. One or more control regions (e.g., CORESETs) may be configured for a set of UEs 115. For example, one or more UEs in UE 115 may monitor or search a control region to obtain control information according to one or more search space sets, and each search space set may include one or more control channel candidates in one or more aggregation levels arranged in a cascaded manner. The aggregation level of a control channel candidate may refer to the amount of control channel resources (e.g., control channel elements (CCEs)) associated with coded information for a control information format having a given payload size. The search space sets may include a common search space set configured for transmitting control information to multiple UEs 115 , and a UE-specific search space set for transmitting control information to a specific UE 115 .
[0060] The network entity 105 may provide communication coverage via one or more cells (e.g., macro cells, small cells, hot spots, or other types of cells, or any combination thereof). The term "cell" may refer to a logical communication entity used to communicate with the network entity 105 (e.g., using a carrier), and may be associated with an identifier (e.g., a physical cell identifier (PCID), a virtual cell identifier (VCID), or other identifier) used to distinguish adjacent cells. In some examples, a cell may also refer to a coverage area 110 or a portion of a coverage area 110 (e.g., a sector) on which the logical communication entity operates. Depending on various factors such as the capabilities of the network entity 105, such cells may range from smaller areas (e.g., structures, subsets of structures) to larger areas. For example, a cell may be or may include a building, a subset of a building, or an external space between or overlapping coverage areas 110, and the like.
[0061] In some examples, the network entities 105 (e.g., base stations 140, RUs 170) may be mobile and thus provide communication coverage for mobile coverage areas 110. In some examples, different coverage areas 110 associated with different technologies may overlap, but the different coverage areas 110 may be supported by the same network entity 105. In some other examples, overlapping coverage areas 110 associated with different technologies may be supported by different network entities 105. The wireless communication system 100 may include, for example, a heterogeneous network in which different types of network entities 105 provide coverage for various coverage areas 110 using the same or different RATs.
[0062] Some UEs 115, such as MTC or IoT devices, may be low-cost or low-complexity devices and may allow automated communication between machines (e.g., via machine-to-machine (M2M) communication). M2M communication or MTC may refer to data communication technology that allows devices to communicate with each other or with a network entity 105 (e.g., base station 140) without human intervention. In some examples, M2M communication or MTC may include communication from devices that integrate sensors or meters to measure or capture information and relay such information to a central server or application that uses the information or presents the information to a person interacting with the application. Some UEs 115 may be designed to collect information or implement automated behavior of machines or other devices. Examples of applications for MTC devices include: smart metering, inventory monitoring, water level monitoring, equipment monitoring, health care monitoring, field survival monitoring, weather and geographic event monitoring, fleet management and tracking, remote security sensing, physical access control, and transaction-based commercial charging.
[0063] The wireless communication system 100 may be configured to support ultra-reliable communication or low-latency communication or various combinations thereof. For example, the wireless communication system 100 may be configured to support ultra-reliable low-latency communication (URLLC). UE 115 may be designed to support ultra-reliable or low-latency or critical functions. Ultra-reliable communication may include private communication or group communication, and may be supported by one or more services (such as push-to-talk, video, or data). Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0064] In some examples, the UE 115 may be configured to support communication directly with other UEs 115 via a device-to-device (D2D) communication link 135 (e.g., according to a peer-to-peer (P2P), D2D, or sidelink protocol). In some examples, one or more UEs 115 in a group that are performing D2D communication may be within a coverage area 110 of a network entity 105 (e.g., a base station 140, a RU 170), which may support aspects of such D2D communication configured (e.g., scheduled) by the network entity 105. In some examples, one or more UEs 115 in such a group may be outside of the coverage area 110 of the network entity 105, or may otherwise be unable or not configured to receive transmissions from the network entity 105. In some examples, a group of UEs 115 communicating via D2D communication may support a one-to-many (1:M) system, in which each UE 115 transmits to each of the other UEs 115 in the group. In some examples, network entity 105 may facilitate scheduling of resources for D2D communications. In some other examples, D2D communications may be performed between UEs 115 without involving network entity 105.
[0065] In some systems, the D2D communication link 135 can be an example of a communication channel (such as a sidelink communication channel) between vehicles (e.g., UE 115). In some examples, the vehicles can communicate using vehicle-to-everything (V2X) communication, vehicle-to-vehicle (V2V) communication, or some combination of these items. The vehicles can signal information related to traffic conditions, signal scheduling, weather, safety, emergency situations, or any other information related to the V2X system. In some examples, vehicles in the V2X system can communicate with roadside infrastructure (such as roadside units) using vehicle-to-network (V2N) communication, or communicate with the network via one or more network nodes (e.g., network entity 105, base station 140, RU 170), or both.
[0066] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or a 5G core (5GC), which may include at least one control plane entity (e.g., a mobility management entity (MME), an access and mobility management function (AMF)) for managing access and mobility and at least one user plane entity (e.g., a serving gateway (S-GW), a packet data network (PDN) gateway (P-GW), or a user plane function (UPF)) for routing packets or interconnecting to an external network. The control plane entity may manage non-access stratum (NAS) functions, such as mobility, authentication, and bearer management of UE 115 served by a network entity 105 (e.g., a base station 140) associated with the core network 130. User IP packets may be delivered through the user plane entity, which may provide IP address allocation and other functions. The user plane entity may be connected to the IP service 150 of one or more network operators. IP services 150 may include access to the Internet, an intranet, an IP Multimedia Subsystem (IMS), or packet-switched streaming services.
[0067] The wireless communication system 100 may operate using one or more frequency bands that may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz). Generally speaking, the region from 300 MHz to 3 GHz is referred to as the ultra-high frequency (UHF) region or decimeter band because the wavelength ranges from about one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features (which may be referred to as clusters), but these waves may be sufficient to penetrate structures so that macro cells provide services to UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than 100 kilometers) than communications using the lower frequencies and longer wavelengths of the high frequency (HF) or very high frequency (VHF) portions of the spectrum below 300 MHz.
[0068] The wireless communication system 100 may also operate using a super high frequency (SHF) region, which may be in the range of 3 GHz to 30 GHz (also known as a centimeter band), or an extremely high frequency (EHF) region of the spectrum (e.g., from 30 GHz to 300 GHz) (also known as a millimeter band). In some examples, the wireless communication system 100 may support millimeter wave (mmW) communications between a UE 115 and a network entity 105 (e.g., a base station 140, a RU 170), and the EHF antennas of the corresponding devices may be smaller and closer together than UHF antennas. In some examples, such techniques may facilitate the use of antenna arrays within the device. However, the propagation of EHF transmissions may be affected by even greater attenuation and shorter range than SHF or UHF transmissions. The techniques disclosed herein may be employed across transmissions using one or more different frequency regions, and the use of frequency bands specified across these frequency regions may vary by country or regulatory agency.
[0069] The wireless communication system 100 may utilize licensed and unlicensed RF spectrum bands. For example, the wireless communication system 100 may use unlicensed bands (such as the 5 GHz Industrial, Scientific, and Medical (ISM) band) to employ license assisted access (LAA), LTE unlicensed (LTE-U) radio access technology, or NR technology. When operating using unlicensed RF spectrum bands, devices such as network entity 105 and UE 115 may employ carrier sensing for conflict detection and avoidance. In some examples, operations performed using unlicensed bands may be based on carrier aggregation configuration (e.g., LAA) in conjunction with component carriers operating using licensed bands. Operations performed using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among others.
[0070] The network entity 105 (e.g., base station 140, RU 170) or UE 115 may be equipped with multiple antennas that can be used to employ technologies such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communication, or beamforming. The antennas of the network entity 105 or UE 115 may be located in one or more antenna arrays or antenna panels, which can support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with the network entity 105 may be located at different geographical locations. The network entity 105 may include an antenna array having a collection of multiple rows and columns of antenna ports that the network entity 105 can use to support beamforming for communications with the UE 115. Similarly, the UE 115 may include one or more antenna arrays that can support various MIMO or beamforming operations. Additionally or alternatively, the antenna panel may support RF beamforming for signals sent via the antenna ports.
[0071] The network entity 105 or UE 115 may use MIMO communication to utilize multipath signal propagation and improve spectral efficiency by sending or receiving multiple signals via different spatial layers. Such a technology may be referred to as spatial multiplexing. The multiple signals may be sent, for example, by a transmitting device via different antennas or different combinations of antennas. Similarly, the multiple signals may be received by a receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords). Different spatial layers may be associated with different antenna ports for channel measurement and reporting. MIMO technologies include: single-user MIMO (SU-MIMO), for which multiple spatial layers are sent to the same receiving device; and multi-user MIMO (MU-MIMO), for which multiple spatial layers are sent to multiple devices.
[0072] Beamforming (which may also be referred to as spatial filtering, directional transmission, or directional reception) is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or direct an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining signals conveyed via antenna elements of an antenna array so that some signals propagating along a particular orientation relative to the antenna array experience constructive interference, while other signals experience destructive interference. Adjustments to signals conveyed via antenna elements may include the transmitting device or the receiving device applying an amplitude offset, a phase offset, or both to signals carried via antenna elements associated with the device. Adjustments associated with each of these antenna elements may be defined by a set of beamforming weights associated with a particular orientation (e.g., relative to the antenna array of the transmitting device or the receiving device or relative to some other orientation).
[0073] The wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. In the user plane, communications at the bearer or PDCP layer may be IP-based. The RLC layer may perform packet segmentation and reassembly to communicate via logical channels. The MAC layer may perform priority processing and multiplexing of logical channels into transport channels. The MAC layer may also implement error detection techniques, error correction techniques, or both to support retransmission to improve link efficiency. In the control plane, the RRC layer may provide the establishment, configuration, and maintenance of an RRC connection that supports a radio bearer for user plane data between the UE 115 and the network entity 105 or the core network 130. The PHY layer may map a transport channel to a physical channel.
[0074] UE 115 and network entity 105 may support retransmission of data to increase the likelihood of data being successfully received. Hybrid automatic repeat request (HARQ) feedback is a technique for increasing the likelihood of correctly receiving data via a communication link (e.g., communication link 125, D2D communication link 135). HARQ may include a combination of error detection (e.g., using a cyclic redundancy check (CRC)), forward error correction (FEC), and retransmission (e.g., automatic repeat request (ARQ)). HARQ can improve throughput at the MAC layer under poor radio conditions (e.g., low signal-to-noise ratio conditions). In some examples, a device may support same-slot HARQ feedback, in which case the device may provide HARQ feedback in a specific time slot for data received via a previous symbol in the time slot. In some other examples, the device may provide HARQ feedback in a subsequent time slot or according to some other time interval.
[0075] In some cases, the communication link 125 may use a first RAT (e.g., 5G or 6G RAT), and may use multiple RATs to provide connectivity for some UEs 115. For example, some UEs 115 located near a CPE 185 may be served using a link 190 of a second RAT (e.g., via a Wi-Fi WLAN in a Wi-Fi coverage area 195 served by the CPE 185), where the CPE 185 communicates with the network entity 105 via the communication link 125 using the first RAT. According to various aspects discussed herein, a scheduler associated with the second RAT may prioritize some communications received via the first RAT based on one or more parameters associated with communications of the first RAT. For example, a scheduler associated with the second RAT may prioritize MBS communications of the first RAT based on MBS information having one or more parameters provided with the MBS communications, where the one or more parameters are associated with communications of the first RAT. Several example references to communications via multiple RATs Figures 2 to 6 Have a discussion.
[0076] Figure 2 An example of MBS service delivery via a wireless communication system 200 supporting multicast service scheduling across multiple RATs according to one or more aspects of the present disclosure is illustrated. The wireless communication system 200 includes a first UE 115-a, a second UE 115-b, a third UE 115-c, and a fourth UE 115-d, which may be reference UEs. Figure 1 The wireless communication system 200 in this example includes a core network 210 (e.g., 5GC or reference Figure 1 The core network 130) and a first RAN 225 (e.g., NG-RAN), which includes one or more network entities (e.g., reference Figure 1 The network entity 105 described above provides a radio air interface between the first RAN 225 and the UE 115 or CPE 185-a using the first RAT. In addition, the CPE 185-a can provide wireless communication using a second RAT (e.g., Wi-Fi) to one or more UEs 115.
[0077] exist Figure 2In the example of FIG. 1 , MBS services 205 may be received at a core network 210 and transmitted to a plurality of UEs 115. The MBS services 205 may provide data for one or more of a plurality of use cases, such as real-time streaming of events using a multicast subscription-based model, broadcast services, delay-sensitive signaling, or high-resolution Internet Protocol Television (IPTV), to name a few examples. In some cases, a replication function 215 at the core network 210 may replicate MBS services 205 for a plurality of UEs for transmission via respective MBS service deliveries 220 for respective UEs 115 (e.g., point-to-point (PTP) MBS streams), or for transmission to two or more UEs 115 via a shared MBS service delivery 240 (e.g., point-to-multipoint (PTM) MBS streams). In this example, a first PDU session 230 for respective MBS service deliveries 220 may be established for a first UE 115-a, and a second PDU session 235 for respective MBS service deliveries 220 may be established for a second UE 115-b. In addition, the shared transmission for the shared MBS service delivery 240 is to both the third UE 115-c and the fourth UE 115-d. In this example, the shared MBS service delivery 240 may be transmitted to the CPE 185-a via the first RAN 225, and the CPE 185-a may provide the MBS service 205 to the third UE 115-c, the fourth UE 115-d, one or more other UEs, or any combination thereof. For example, the CPE 185-a may use the first Wi-Fi link 250-a (e.g., reference 1 Figure 1 The link 190 described above) can be used to communicate with the third UE 115-c, and the second Wi-Fi link 250-b (e.g., reference Figure 1 In some cases, the first RAN 225 capable of MBS may dynamically determine whether to perform PTP or PTM for a UE 115 to receive the MBS service 205 based on several factors, such as proximity to the same transmit receive point (TRP) of the first RAN 225, characteristics of the MBS service 205 to be transmitted (e.g., initial transmission or retransmission, delay tolerance of data, etc.), channel conditions observed at the UE 115, etc.
[0078] In some cases, the CPE 185-a may provide "list mile" connectivity between the core network 210 and the third UE 115-c and the fourth UE 115-d, which may help enhance the efficiency and reliability of communications between the core network 210 and the third UE 115-c and the fourth UE 115-d. For example, the third UE 115-c and the fourth UE 115-d may be located in a structure that prevents reliable connectivity with the first RAN 225 using the first RAT, but may be able to reliably connect to the CPE 185-a using the second RAT. The CPE 185-a may then be located at or in a location in the structure that provides a reliable connection with the first RAN 225 using the first RAT, and may thus provide an efficient and reliable end-to-end connection for the third UE 115-c and the fourth UE 115-d using both the first RAT and the second RAT. In some cases, the final portion of providing wireless connectivity using the CPE 185-a may be referred to as fixed wireless access (FWA). CPE 185-a may include, for example, a mobile router, a soft AP CPE, a gateway CPE, or an outdoor unit (ODU) that may have, for example, an associated indoor AP.
[0079] In some cases, the MBS service 205 may be received at the CPE 185-a (via the first RAN 225), where the CPE 185-a has a WAN interface (e.g., a 5G RAN interface) and an Ethernet or Wi-Fi interface (or both) for LAN clients such as the third UE 115-c and the fourth UE 115.d. However, the existing LAN system may place the associated data in a buffer for transmission via the second RAT after receiving the MBS service 205, and the WAN may consider the associated data to be successfully received. As discussed herein, in the case where the MBS service 205 is placed in a traditional buffer for transmission, other services at the CPE may cause the MBS service 205 to be delayed. Such a delay may result in the QoS objectives of the MBS service 205 not being met. In addition, in some cases, a relatively large number of UEs 115 may be served via the CPE 185-a, where multiple instances of the MBS service 205 are placed in a buffer for transmission to the UE 115. In some cases, the second RAT may provide multicast and broadcast modes, but such modes may provide relatively low data rates (eg, because such transmissions are set to the lowest possible decodable rate in order to be received by devices that only support the low rate).
[0080] In some cases, in order to provide a higher effective data delivery rate, the MBS service 205 can be converted to unicast data for each served client, which can be sent at a much higher rate than the rate available in the multicast and broadcast modes, so that even in the case where a large number of clients are to receive the MBS service 205, the transmission of the unicast data improves efficiency. In addition, since the frame is sent as unicast, the transmission rate can be further enhanced based on the client reception capability, and thus such a technique can provide more efficient use of air time. However, as discussed above, in the case where the MBS service 205 is placed in the transmission queue of each served client, even when converted to unicast data for transmission to the served client, the latency caused by other services may result in the QoS target of the MBS service 205 not being met. In some cases, the first RAN 225 can support QoS control per MBS session, where for an MBS session, one or more QoS flows can be guaranteed bit rate (GBR) or non-GBR flows. A QoS flow may have associated QoS parameters (e.g., 5G QoS Identifier (5QI) parameters) based on the data sent via the flow.
[0081] According to various aspects discussed herein, CPE 185-a can provide information to enable MBS service 205 awareness at the WLAN scheduler. Such MBS service 205 awareness can help improve user experience and can also enhance overall network efficiency. In some cases, the WLAN scheduler can use the awareness of MBS service to prioritize MBS service with other WLAN services 205 based on the parameters of the MBS service. Example reference to a wireless communication system with CPE 185 according to various aspects of the present disclosure Figure 3 discuss.
[0082] Figure 3 An example of a wireless communication system 300 with a CPE 185-b supporting multicast service scheduling across multiple RATs according to one or more aspects of the present disclosure is illustrated. The wireless communication system 300 includes a first UE 115-e to an nth UE 115-f, which may be reference UEs 115-e to 115-f. Figure 1 and Figure 2 In this example, the wireless communication system 200 includes a network entity 105-b and a CPE 185-b, which may be reference Figure 1 and Figure 21 and 185. In this example, the network entity 105-b can communicate with the CPE 185-b via a first link 335 using a first RAT (e.g., 5G), and the CPE 185-b can communicate with the UEs 115-e to 115-f via a second link 350 to an nth link 355 using a second RAT (e.g., Wi-Fi). In some cases, the network entity 105-b can communicate directly with one or more of the UEs 115 via associated links 340 to 345.
[0083] exist Figure 3 In an example of , CPE 185-b may include a CPE connection manager 305, a WLAN scheduler 310, a WAN modem 315 (e.g., a 5G or 6G modem that communicates in a first RAN according to a first RAT), a WLAN modem 320 (e.g., a Wi-Fi AP that communicates in a second RAN according to a second RAT), a QoS manager 325, and a CPE data path manager 330. The CPE 185-b may include associated hardware and software to perform various techniques as discussed herein, such as a modem and associated chipset for communicating (e.g., via multiple RANs, LANs, WANs, or combinations thereof), antennas for communicating using different RATs, a wired port for accessing a WAN / LAN (e.g., Ethernet, digital subscriber line (DSL), Gigabit Ethernet passive optical network (GPON), etc.), one or more processors or controllers that provide various managers, and one or more memories that can buffer data and store instructions that can be executed to perform one or more of the functions described herein.
[0084] As discussed herein, in some cases, the CPE 185-b may receive MBS traffic (such as multicast data) from a first RAN and send the MBS traffic to two or more served UEs 115-e to 115-f via a second RAN, such that a single packet of the multicast data is sent in a one-to-many manner. In some cases, the CPE connection manager 305 may manage the connections of different networks, the WLAN scheduler 310, the QoS manager 325, and the CPE data path manager 330. The QoS manager 325 may monitor and configure various QoS parameters for different data flows (including MBS data flows provided via the CPE 185-b). The CPE data path manager 330 routes the various flows via different data paths based on information from the WLAN scheduler 310, one or more configured rules (e.g., QoS rules), or any combination thereof. Thus, the WLAN scheduler 310 in conjunction with the data path manager 330 may perform traffic steering, traffic switching, etc. between different data paths for LAN or WAN communications.
[0085] In some cases, the WLAN scheduler 310 may use FWA LAN communications to provide one or more of the UEs 115 for a multicast session over the WAN, and may prioritize data traffic associated with the multicast session based on awareness of the multicast traffic and one or more parameters associated therewith. The WLAN scheduler 310 may use multicast traffic awareness to manage a relatively large number of WLAN clients (e.g., UEs 115-e to 115-f) participating in the multicast session, which may result in a relatively large amount of air time spent in sending multicast traffic and, in some cases, may result in back pressure due to a one-to-many relationship between multicast packets received via the WAN modem 315 and associated multiple multicast packets sent via the WLAN modem 320. In some cases, the CPE 185-b may have a shared buffer between the WLAN modem 320 and the WAN modem 315, and the multicast traffic awareness may allow for appropriate allocation of the shared buffer. One or more parameters associated with the multicast traffic may also indicate relatively high bandwidth versus relatively low bandwidth multicast, which may allow for appropriate resource allocation for different traffic flows (e.g., a multicast data flow and one or more other LAN or WAN flows). Furthermore, one or more parameters associated with the multicast service may indicate whether the multicast service has a relatively high QoS or is latency critical, which may allow WLAN scheduling that provides differentiated services (eg, even within the same AC).
[0086] According to various aspects, the WLAN scheduler 310 may use one or more parameters associated with the multicast stream to perform efficient WLAN scheduling. In some cases, the one or more parameters may include the number of served clients to receive the multicast stream, and the WLAN scheduler 310 may throttle the number of clients associated with the stream to provide enhanced overall system performance and network efficiency (e.g., based on a throttling configuration that is based on the FWA CPE configuration or received from the WAN core network, such as a threshold number of clients that can be served). In some cases, the one or more parameters may include a 5QI parameter (e.g., a multicast stream with 5QI<82 may be less critical and managed as part of a standard AC queue, a multicast stream with 5QI≥82 may be delay-critical and prioritized over other streams, and a multicast stream with 5QI=65 or 69 may be treated as if it were 5QI≥82).
[0087] In some cases, one or more parameters may include the bandwidth of the multicast stream, which may allow for more efficient scheduling based on the expected data rate. In some cases, one or more parameters may include the capabilities of each WLAN client (such as the first UE 115-e to the nth UE 115-f), which may allow for the implementation of multiple access technologies. For example, if the UEs 115-e to 115-f are capable of OFDMA or MU-MIMO, the WLAN scheduler 310 may use OFDMA or MU-MIMO for the multicast stream, and if one or more of the UEs 115-e to 115-f are capable of single-user (SU) operation, the WLAN scheduler may use SU communication for the multicast stream to such UEs 115. In some cases, one or more parameters may include the number of non-multicast MBS streams, which may indicate the resources that may be required for such streams. In some cases, one or more parameters may include a feedback configuration for the multicast stream, which may indicate the QoS or delay criticality of the MBS stream. For example, a relatively low QoS may be indicated if the multicast stream is configured without HARQ ACK / NACK feedback, a higher QoS may be indicated if the multicast stream is configured with only NACK feedback, and the highest QoS may be indicated if the multicast stream is configured with ACK / NACK feedback.
[0088] Figure 4 An example of a process flow 400 for supporting multicast traffic scheduling across multiple RATs according to one or more aspects of the present disclosure is illustrated. The process flow 400 includes a UE 115-g, which may be a reference Figures 1 to 3 The process flow 400 also includes a network entity 105-c and a CPE 185-c including a WLAN scheduler 405 and a 5G modem 410, which may be referenced Figure 1-3 Examples of corresponding devices are described. The process flow 400 can implement aspects of the wireless communication system 100, 200, or 300. For example, the process flow 400 can support multicast traffic scheduling across multiple RATs.
[0089] In the following description of the process flow 400, the signaling exchanged between the UE 115-g, the WLAN scheduler 405, the 5G modem 410, and the network entity 105-c may be exchanged in a different order than the example order shown, or the operations performed by the UE 115-g, the WLAN scheduler 405, the 5G modem 410, and the network entity 105-c may be performed in a different order or at a different time. Some operations may also be omitted from the process flow 400, and other operations may be added to the process flow 400. In addition, the WLAN scheduler 405 and the 5G modem 410 are shown for illustration and discussion purposes only, and the techniques discussed herein may be applied to other RAN / RATs.
[0090] At 415, the network entity 105-c may announce the multicast session. In some cases, the multicast session may provide real-time streaming of events using a multicast subscription-based model, critical delay-sensitive signaling, high-resolution IPTV, etc. In some cases, the announcement of the multicast session may provide one or more parameters associated with the session, such as an expected bandwidth or data rate, a periodicity of multicast transmissions, a feedback configuration, a QoS of the multicast stream, or any combination thereof. For example, the announcement of the multicast session may be provided in MBS configuration information provided in a medium access control (MAC) control element (CE) or in other control information or system information. In some cases, the multicast session announcement may be received directly by the UE 115-g via the 5G RAN, or may be received via the CPE 185-c and a WLAN associated with the WLAN scheduler 405 according to the FWA configuration.
[0091] At 420, the UE 115-g may send a multicast session request to the WLAN scheduler 405. In some cases, the UE 115-g may be configured for FWA via a WLAN associated with the CPE 185-c and may send the multicast session request based on the multicast session announcement. At 425, the WLAN scheduler 405 and the 5G modem 410 may exchange information related to the multicast session. For example, the WLAN scheduler 405 and the 5G modem 410 may exchange information related to the multicast session, such as 5QI information, bandwidth of the multicast stream, feedback configuration for the multicast stream, or any combination thereof.
[0092] At 430, the WLAN scheduler 405 may determine to grant a multicast flow. In some cases, the determination may be based on one or more parameters of the multicast session, such as information related to the multicast session exchanged with the 5G modem, the number of clients requesting the multicast session, the capabilities of the clients requesting the multicast session, the number of non-MBS flows served by the CPE 185-c, or any combination thereof. In some cases, a multicast session from the LAN may be served / granted only if the number of clients is below an acceptable limit (e.g., a configured threshold), one or more QoS constraints relative to the 5QI are met, the capabilities of the served UE 115 for OFDMA or MU-MIMO (e.g., flows of UEs with OFDMA / MU-MIMO capabilities are given priority SU flows for scheduling multicast services), a failure rate of clients (e.g., if the number of transmission failures for a particular client exceeds a threshold, the client may be removed from the multicast session), or any combination thereof. Example References to Multicast Service Grants and Associated Prioritization Figure 5In some cases, to avoid competition from other flows, an alternative AC queue for low-latency multicast (e.g., for multicast flows with 5QI>82) may be implemented. An example of such an alternative AC queue is shown in Figure 6 discuss.
[0093] At 435, based on the determination that the multicast flow is permitted, the WLAN scheduler 405 may send a multicast session request to the 5G modem 410. At 440, the 5G modem 410 may send the multicast session request to the network entity 105-c. At 445, the network entity 105-c may send multicast data to the 5G modem 410 based on the multicast session request.
[0094] At 450, the 5G modem may format a multicast indication associated with the multicast stream. In some cases, the multicast indication may provide one or more parameters associated with the multicast stream, or may indicate an ID of a multicast session associated with a previous multicast session request. In some cases, at 455, the multicast indication may be provided to the WLAN scheduler 405 along with the multicast data, or may be provided separately from the multicast data. At 460, in some cases where the multicast stream has a configured NACK or ACK / NACK feedback, the 5G modem 410 may send ACK / NACK feedback to the network entity 105-c.
[0095] At 465, the WLAN scheduler 405 may prioritize the multicast data and other WLAN traffic. In some cases, the multicast data is prioritized based on one or more parameters associated with the multicast session, as discussed herein. At 470, the WLAN scheduler 405 may schedule the multicast data for transmission by a WLAN modem (e.g., a Wi-Fi modem) to the UE 115-g.
[0096] Figure 5 An example of a flowchart 500 for supporting multicast service scheduling across multiple RATs according to one or more aspects of the present disclosure is illustrated. The flowchart 500 may be implemented in a system supporting multicast service scheduling across multiple RATs, such as the system described in the accompanying drawings. Figures 1 to 4 The operations as discussed with reference to flowchart 500 may be performed by one or more components of a CPE, such as a WLAN scheduler, as discussed herein.
[0097] The WLAN scheduler may receive an MBS session initiation request at 505. In some cases, the MBS session initiation request may be received from a UE in a FWA configuration over which a CPE communicates with a first RAN using a first RAT and the CPE communicates with a UE in a second RAN using a second RAT.
[0098] At 510, the WLAN scheduler may determine whether a client limit is exceeded for the MBS session. In some cases, the client limit may be based on a FWA CPE limit, or may be based on configuration information from the first RAN. In some cases, the client limit may be set based on the capacity of multicast communications via the CPE, the number of clients served via the CPE, the type of service associated with the MBS session, or any combination thereof. At 515, if it is determined that the client limit is exceeded, the WLAN scheduler may deny the session request. In some cases, the WLAN scheduler may provide an indication to the UE that the MBS session is denied, and the UE may attempt to directly initiate the MBS session via the first RAN.
[0099] At 520, if it is determined that the client limit is not exceeded, the WLAN scheduler may determine whether the QoS value is less than a first threshold (e.g., a 5QI value is less than 82). At 525, if it is determined that the QoS value is less than the first threshold, the WLAN scheduler may determine whether the QoS value has a specific value corresponding to a higher priority service (e.g., a 5QI value of 65 or 69). At 530, if it is determined that the QoS threshold does not have a specific value, the WLAN scheduler may map packets of the MBS session to the AC queue according to standard WLAN AC mapping, and at 565, the WLAN scheduler may admit the flow for the MBS session.
[0100] At 535, if the QoS value is greater than or equal to the first threshold, or if the QoS value is equal to a specific value, the WLAN scheduler may determine whether the data rate associated with the MBS session is less than the rate threshold. At 540, if it is determined that the data rate is not less than the rate threshold, the WLAN scheduler may determine whether all clients requesting the MBS session have MU-MIMO capabilities. At 545, if it is determined that all clients do not have MU-MIMO capabilities, the WLAN scheduler may map packets of the MBS session to an alternative AC queue associated with low-latency multicast communication, and at 565, the WLAN scheduler may grant a flow for the MBS session. At 560, if it is determined that all clients have MU-MIMO capabilities, the WLAN scheduler may schedule downlink MU-MIMO for the client requesting the MBS session, and at 565, the WLAN scheduler may grant a flow for the MBS session.
[0101] At 550, if it is determined that the data rate is less than the data rate threshold, the WLAN scheduler may determine whether all clients requesting the MBS flow are OFDMA capable. If all clients are not OFDMA capable, at 560, the WLAN scheduler may map packets for the MBS session to an alternative AC queue associated with low-latency multicast communication, and at 565, the WLAN scheduler may grant the flow for the MBS session. At 555, if it is determined that all clients are OFDMA capable, the WLAN scheduler may schedule downlink OFDMA for the clients requesting the MBS session, and at 565, the WLAN scheduler may grant the flow for the MBS session.
[0102] Figure 6 An example of an access category queue 600 supporting multicast service scheduling across multiple RATs according to one or more aspects of the present disclosure is illustrated. The access category queue 600 may be used in a system supporting multicast service scheduling across multiple RATs (such as in a system such as a reference system). Figures 1 to 5 The wireless communication system is implemented as described above.
[0103] exist Figure 6In an example of , a WLAN scheduler (such as a WLAN scheduler of a FWA CPE) may have granted a multicast flow as discussed herein (e.g., based on one or more parameters associated with the flow). The WLAN scheduler may receive a MAC service data unit (MSDU) 605, which may be provided to a packet mapping function 610. The packet mapping function 610 may map packets of the MSDU to one of a plurality of ACs 615, including a background (BK) AC 620, a best effort (BE) AC 625, an alternative video (A_VI) AC 630, a video (VI) AC 635, an alternative voice (A_VO) AC 640, and a voice (VO) AC 645. The mapped ACs may then be mapped to one of the plurality of transmit AC queues 650, wherein the BK AC 620 is mapped to the BK transmit queue 655, the BE AC 625 is mapped to the BE transmit queue 660, the A_VI AC 630 and the VI AC 635 are mapped to the VI transmit queue 665, and the A_VO AC 640 and the VO AC 645 are mapped to the VO transmit queue 670. In this example, multicast packets having a QoS value exceeding a QoS threshold (e.g., 5QI>82) or having a pre-specified QoS value (e.g., 5QI=65 or 69) from the VI AC 635 or the VO AC 645 may be mapped to an alternative low latency (LL) transmit queue 675. In such a case, the WLAN scheduler may schedule packets from the alternative LL transmit queue 675 before packets from the other transmit queues 655 to 670. Therefore, a relatively high QoS multicast packet may be provided with a higher transmission priority, and the WLAN scheduler may provide enhanced network efficiency and enhanced user experience for the multicast data.
[0104] Figure 7 A block diagram 700 of a device 705 supporting multicast traffic scheduling across multiple RATs according to one or more aspects of the present disclosure is shown. The device 705 may be an example of aspects of a UE 115, a CPE 185, or a network entity 105 as described herein. The device 705 may include a receiver 710, a transmitter 715, and a communication manager 720. The device 705 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).
[0105] The receiver 710 may provide means for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to multicast service scheduling across multiple RATs). The information may be delivered to other components of the device 705. The receiver 710 may utilize a single antenna or a collection of multiple antennas. In some cases, the receiver 710 may include multiple receivers for different RATs (e.g., wireless modems for different RATs).
[0106] The transmitter 715 may provide means for transmitting signals generated by other components of the device 705. For example, the transmitter 715 may transmit information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to multicast service scheduling across multiple RATs). In some examples, the transmitter 715 may be co-located with the receiver 710 in a transceiver module. The transmitter 715 may utilize a single antenna or a collection of multiple antennas. In some cases, the transmitter 715 may include multiple transmitters for different RATs (e.g., wireless modems for different RATs).
[0107] The communication manager 720, the receiver 710, the transmitter 715, or various combinations thereof, or various components thereof, may be examples of means for performing various aspects of multicast traffic scheduling across multiple RATs as described herein. For example, the communication manager 720, the receiver 710, the transmitter 715, or various combinations thereof, or components thereof, may support methods for performing one or more of the functions described herein.
[0108] In some examples, the communication manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be implemented in hardware (e.g., in a communication management circuit). The hardware may include a processor, a digital signal processor (DSP), a central processing unit (CPU), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, a microcontroller, discrete gate or transistor logic components, discrete hardware components, or any combination thereof that is configured to or otherwise supports components for performing the functions described in the present disclosure. In some examples, the processor and a memory coupled to the processor may be configured to perform one or more of the functions described herein (e.g., by executing instructions stored in the memory by the processor).
[0109] Additionally or alternatively, in some examples, the communication manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be implemented in code executed by a processor (e.g., as communication management software or firmware). If implemented in code executed by a processor, the functionality of the communication manager 720, the receiver 710, the transmitter 715, or various combinations or components thereof may be performed by a general purpose processor (e.g., configured as or otherwise supporting components for performing the functions described in the present disclosure), a DSP, a CPU, an ASIC, an FPGA, a microcontroller, or any combination of these or other programmable logic devices.
[0110] In some examples, the communication manager 720 can be configured to perform various operations (e.g., receive, obtain, monitor, output, send) using or otherwise cooperating with the receiver 710, the transmitter 715, or both. For example, the communication manager 720 can receive information from the receiver 710, transmit information to the transmitter 715, or integrate with the receiver 710, the transmitter 715, or both to obtain information, output information, or perform various other operations as described herein.
[0111] According to examples disclosed herein, the device 705 may support wireless communications. For example, the receiver 710 may be configured to or otherwise support components for receiving multicast data associated with a multicast service via a first wireless network using a first RAT, wherein the multicast data is to be provided to one or more clients via a second wireless network using a second RAT, and wherein the multicast service has a set of multicast service parameters. The communication manager 720 may be configured to or otherwise support components for sending an information message indicating one or more multicast service parameters in the set of multicast service parameters to a scheduler of the second wireless network (e.g., which in some aspects may be included within the communication manager). The communication manager 720 may be configured to or otherwise support components for sending the multicast data to the scheduler for transmission via the second wireless network.
[0112] Additionally or alternatively, according to examples disclosed herein, the device 705 may support wireless communications. For example, the communication manager 720 may be configured to or otherwise support components for receiving, from a wireless modem, an information message indicating one or more multicast service parameters associated with a multicast service provided via a wireless modem using a first wireless network utilizing a first RAT. The communication manager 720 may be configured to or otherwise support components for receiving, from the wireless modem, at least a first multicast data communication, wherein the first multicast data communication is to be sent to one or more clients via a second wireless network utilizing a second RAT. The transmitter 715 may be configured to or otherwise support components for sending the first multicast data communication to at least a first client via a second wireless network based on a priority ranking of the first multicast data communication relative to one or more other data communications to be sent via the second wireless network, wherein the priority ranking is based on the one or more multicast service parameters.
[0113] By including or configuring a communication manager 720 according to the examples described herein, the device 705 (e.g., a processor controlling or otherwise coupled to the receiver 710, the transmitter 715, the communication manager 720, or a combination thereof) may support techniques for prioritizing multicast communications in traffic scheduling across multiple RATs, which provide enhanced reliability for multicast streams sent to UEs across multiple RATs, enhance network efficiency, enable latency-sensitive multicast streams, and provide an enhanced user experience.
[0114] Figure 8 A block diagram 800 of a device 805 supporting multicast traffic scheduling across multiple RATs according to one or more aspects of the present disclosure is shown. The device 805 may be an example of aspects of the device 705, UE 115, CPE 185, or network entity 105 as described herein. The device 805 may include a receiver 810, a transmitter 815, and a communication manager 820. The device 805 may also include a processor. Each of these components may communicate with each other (e.g., via one or more buses).
[0115] The receiver 810 may provide means for receiving information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to multicast service scheduling across multiple RATs). The information may be communicated to other components of the device 805. The receiver 810 may utilize a single antenna or a collection of multiple antennas.
[0116] The transmitter 815 may provide means for transmitting signals generated by other components of the device 805. For example, the transmitter 815 may transmit information (such as packets, user data, control information, or any combination thereof) associated with various information channels (e.g., control channels, data channels, information channels related to multicast service scheduling across multiple RATs). In some examples, the transmitter 815 may be co-located with the receiver 810 in a transceiver module. The transmitter 815 may utilize a single antenna or a collection of multiple antennas.
[0117] The device 805 or its various components may be examples of components for performing various aspects of multicast traffic scheduling across multiple RATs as described herein.

25. The apparatus of claim 24, wherein the instructions are further executable by the processor to cause the apparatus to: A determination is made to grant or deny the multicast service based at least in part on the one or more multicast service parameters.
26. An apparatus according to claim 24, wherein the one or more multicast service parameters include one or more of the number of clients associated with the multicast service, a quality of service parameter associated with the multicast service, a data rate target for the multicast service, a number of non-multicast data streams to be communicated concurrently with the multicast service, a capability of each of the clients associated with the multicast service, or a feedback scheme associated with the multicast service.
27. The apparatus of claim 26, wherein the instructions are further executable by the processor to cause the apparatus to: Granting or denying the multicast service is determined based at least in part on the capabilities of each of the clients associated with the multicast service.
28. The apparatus of claim 24, wherein the instructions are further executable by the processor to cause the apparatus to: mapping data communications associated with the multicast service to a separate access category (AC) queue of the second wireless network; and Data transmission from the individual AC transmit queue to the one or more clients is scheduled based at least in part on a higher priority of the individual AC transmit queue than one or more other AC queues.
29. The apparatus of claim 28, wherein mapping the data communications associated with the multicast service to the separate AC transmit queue is based at least in part on one or more quality of service (QoS) thresholds associated with the separate AC transmit queue and the one or more other AC queues, and a QoS associated with the multicast service that indicates an amount of delay tolerance for the multicast service.
30. The apparatus of claim 28, wherein mapping the data communications associated with the multicast service to the separate AC transmit queue is based at least in part on a feedback scheme of the multicast service, and wherein a no feedback scheme or a negative acknowledgement feedback scheme is mapped to a lower priority AC queue, and an acknowledgement / negative acknowledgement feedback scheme is mapped to the separate AC transmit queue having a higher priority than the one or more other AC queues.
