Method and apparatus for wireless communication in a base station, and memory

Abstract

Methods, systems, and devices for wireless communication are described. Some wireless communication systems may support a determination of user equipment (UE) capabilities, such as a category or coverage level for broadcast or multicast content. In some cases, a radio interface may be configured to compensate for an indicated capability of a target UE. For example, a base station may receive an indication of a particular target UE capability. The target UE capability may be specified by a service provider to distribute multicast or broadcast content and subsequently associated with a radio interface between the base station and the target UE. The radio interface may then be configured based on the indicated capability of the target UE, for example, by configuring a transport block size or bandwidth.The base station can then transmit broadcast or multicast content to the EU using the configured radio interface.

Description

1 / 81 METHOD AND APPARATUS FOR WIRELESS COMMUNICATION IN A BASE STATION, AND MEMORY CROSS-REFERENCES

[0001] This patent application claims priority over Indian patent application No. 2017 / 41004261 by Rico Alvarino et al., entitled CAPABILITY AND COVERAGE DETERMINATION FOR MULTIMEDIA BROADCAST MULTICAST SERVICE, filed on February 6, 2017, assigned to the assignee of this application, and which is expressly incorporated herein by reference in its entirety. FUNDAMENTALS

[0002] The following generally refers to wireless communication, and more specifically to determining capacity and coverage for multimedia broadcast and multi-broadcast services.

[0003] Wireless communication systems are widely developed to provide various types of communication content such as voice, video, packet data, message sending, broadcasting, and so on. These systems can support communication with multiple users by sharing available system resources (e.g., time, frequency, and power). Examples of such multiple access systems include code-division multiple access (CDMA) systems, time-division multiple access (TDMA) systems, frequency-division multiple access (FDMA) systems, and orthogonal frequency-division multiple access (OFDMA) systems (e.g., a Long Term Evolution (LTE) system, or a New Radio (NR) system). A wireless multiple access communication system may include multiple base stations. Petition 870240096014, dated 08 / 11 / 2024, page 6 / 178 2 / 81 or access network nodes, each simultaneously supporting communication for multiple communication devices, which may otherwise be known as user equipment (UE).

[0004] In some wireless communication systems that support multicast and / or broadcast transmissions, different UEs may have varying capabilities, such as being able to support a specific bandwidth or maximum transport block size (TB) through a radio interface with a base station. Therefore, when a UE with different capabilities is added to the field, the newly added UE may not support the same capabilities being used by other connected UEs. In such cases, it may be desirable to implement techniques for configuring radio resources to accommodate a range of UE capabilities. SUMMARY

[0005] The techniques described refer to improved methods, systems, devices, or apparatus that support the determination of UE capabilities, such as category or coverage level for broadcasting or multi-broadcasting content (e.g., content delivered using Multimedia Broadcasting Service (MBMS)).

For example, a base station may receive an indication of a capability of a particular target UE.

[0046] In Multimedia Broadcasting and Multicasting Service (MBMS), the broadcasting or multicasting of content provided by a service provider may be transmitted to Petition 870240096014, dated 08 / 11 / 2024, page 18 / 178 14 / 81 From a broadcast and multicast service center (BMSC) to a base station to distribute one or more devices (EDs) using, for example, single-cell point-to-multipoint (SC-PTM) techniques. Broadcast or multicast distribution can allow for flexible scheduling and efficient resource utilization, while limiting the complexity of operations and hardware required to receive the data. This, in turn, can enable efficient narrowband communications, such as narrowband Internet of Things (NB-IoT) or enhanced machine-to-machine communication (eMTC), within a network.

[0047] However, in MBMS, UEs (e.g., IoT or MTC devices) may have different capabilities (e.g., supporting different transport block sizes (TB) or different bandwidths). Each UE may belong to a category based on its capabilities. However, for example, when another UE is added to the field, the UE may exhibit different capabilities than the UEs already connected. The service provider may, accordingly, inform the base station via the BMSC of a configuration supported by the UE. In this way, a method to optimize radio resources to communicate with a UE that has not yet established a connection with a corresponding BMSC may be desirable.

[0048] In some examples, a service provider may explicitly indicate to a BMSC the category for a base station to use for a radio interface with a UE. Additionally or alternatively, the category may be implicitly determined by the base station from the signaling received from the BMSC. In some cases, a Petition 870240096014, dated 08 / 11 / 2024, page 19 / 178 15 / 81 range of service identifiers (e.g., Temporary Mobile Group Identifiers (TMGIs)) may be reserved for a category, and BMSC may determine and transmit a corresponding service identifier to the base station based on the category to be used. A maximum UE capacity may be indicated, correspondingly, in a User Service Description (USD) in a transmission, in a single-cell multipoint control channel (SC-MCCH), or in a System Information Block (SIB).

[0049] In some instances, different UEs in a multi-UE deployment may prefer or utilize different levels of coverage enhancement. The service provider may, correspondingly, indicate to the BMSC an expected coverage enhancement for the services. Additionally or alternatively, the BMSC may set a target for a level of successful reception of transmissions, and adjust the level of coverage enhancement to achieve the determined target based on reports from a UE indicating whether the UE successfully received the transmissions.

[0050] Aspects of the description are initially described in the context of a wireless communications system. Aspects of the description are further illustrated by and described with reference to device diagrams, system diagrams, and flowcharts that relate to determining capacity and coverage for multimedia broadcast and multicast services.

[0051] Figure 1 illustrates an example of a 100 wireless communications system that supports the Petition 870240096014, dated 08 / 11 / 2024, page 20 / 178 16 / 81 Determination of capacity and coverage for multimedia broadcast and multicast services, in accordance with the aspects of this description. The 100 wireless communications system includes 105 base stations, 115 UEs, and a 130 core network. In some instances, the 100 wireless communications system may be a Long Term Evolution (LTE) or Enhanced TE (LTE-A) network, or a New Radio (NR) network. In some cases, the 100 wireless communications system may support enhanced broadband communications, ultra-reliable (i.e., critical) communications, low-latency communications, and communications with low-cost, low-complexity devices. The 100 wireless communications system may support UE category designation to enable efficient deployment of radio resources to the 115 UEs that have not yet communicated with a BMSC.

[0052] Base stations 105 can communicate wirelessly with UEs 115 through one or more base station antennas. Each base station 105 can provide communication coverage for a respective geographic coverage area 110. The communication links 125 illustrated in the wireless communication system 100 can include uplink (UL) transmissions from a UE 115 to a base station 105, or downlink (DL) transmissions from a base station 105 to a UE 115. Control and data information can be multiplexed onto an uplink or downlink channel according to various techniques. Control and data information can be multiplexed onto a downlink channel, for example, using time-division multiplexing (TDM) techniques, frequency-division multiplexing (FDM) techniques, or techniques Petition 870240096014, dated 08 / 11 / 2024, page 21 / 178 17 / 81 Hybrid TDM-FDM. In some examples, the control information transmitted during a transmission time interval (TTI) of a downlink channel can be cascaded between different control regions (e.g., between a common control region and one or more UE-specific control regions).

[0053] UEs 115 can be distributed throughout the wireless communications system 100, and each UE 115 can be stationary or mobile. A UE 115 may also be referred to as a mobile station, a subscriber station, a mobile unit, a subscriber unit, a wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal, a mobile terminal, a wireless terminal, a remote terminal, an appliance, a user agent, a mobile client, a client, or some other suitable terminology.A UE 115 can also be a mobile phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a tablet computer, a laptop computer, a cordless phone, a personal electronic device, a portable device, a personal computer, a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, an MTC device, a home appliance, an automobile, or similar.

[0054] In some cases, a UE 115 can also communicate directly with other UEs (for example, using a non-hierarchical (P2P) or device-to-device (D2D) protocol). One or more of a Petition 870240096014, dated 08 / 11 / 2024, page 22 / 178 18 / 81 groups of UEs 115 using D2D communications may be within the coverage area 110 of a cell. Other UEs 115 in such a group may be outside the coverage area 110 of a cell, or otherwise unable to receive transmissions from a base station 105. In some cases, groups of UEs 115 communicating via D2D communications may use a one-to-many (1:M) system, in which each UE 115 transmits to every UE 115 in the group. In some cases, a base station 105 facilitates the scheduling of resources for D2D communications. In other cases, D2D communications are carried out independently of a base station 105.

[0055] Some UEs 115, such as devices Machine-to-Machine (M2M) or IoT devices can be low-cost or low-complexity devices that provide automated communication between machines. M2M or MTC can refer to data communication technologies that allow devices to communicate with each other or a base station without human intervention. For example, M2M or MTC can refer to communications from devices that integrate sensors or meters to measure or capture information and relay that information to a central server or application program that can use the information or present the information to humans interacting with the program or application. Some UEs 114 may be designed to collect information or enable automated machine behavior. Examples of applications for MTC devices include smart metering, inventory monitoring, water level monitoring, and monitoring of... Petition 870240096014, dated 08 / 11 / 2024, page 23 / 178 19 / 81 equipment, health care monitoring, wildlife monitoring, weather or geological event monitoring, fleet management and tracking, remote security sensor, physical access control, and transaction-based commercial billing.

[0056] In some cases, an MTC device can operate using half-duplex (one-way) communications at a reduced peak rate. MTC devices can also be configured to enter a deep latency power saving mode when not engaged in active communications. In some cases, MTC or IoT devices may be designed to support mission-critical functions, and the wireless communications system may be configured to provide ultra-reliable communications for those functions.

[0057] Base stations 105 can communicate with the core network 130 and with each other. For example, base stations 105 can interface with the core network 130 via backhaul access channel links 132 (e.g., (S1, etc.). Base stations 105 can communicate with each other via return access channel links 134 (e.g., X2, etc.), directly or indirectly (e.g., via the core network 130). Base stations 105 can perform radio configuration and programming to communicate with UEs 115, or they can operate under the control of a base station controller (not shown). In some instances, base stations 105 may be macro cells, small cells, hot spots, or similar. Base stations 105 may also be referred to as eNodeBs (eNBs) 105.

[0058] A base station 105 can be connected Petition 870240096014, dated 08 / 11 / 2024, p. 24 / 178 20 / 81 via an S1 interface to the core network 130. The core network may be an evolved packet core (EPC), which may include at least one mobility management entity (MME), at least one S-GW, and at least one P-GW. The MME may be the control node that processes signaling between UE 115 and the EPC. All user Internet Protocol (IP) packets may be transferred through the S-GW, which, in turn, may be connected to the P-GW. The P-GW may provide IP address allocation in addition to other functions. The P-GW may be connected to network operator IP services. Operator IP services may include the Internet, Intranet, an IP Multimedia Subsystem (IMS), and a Packet-Switched Sequencing Service (PSS).

[0059] The core network 130 can provide authentication, access authorization, tracking, IP connectivity, and other access, routing, or mobility functions. At least some of the network devices, such as the base station 105-a, may include subcomponents, such as an access network entity 105-b, which may be an example of an access node controller (ANC) 105. Each access network entity 105-b can communicate with a number of UEs 115 through several other access network transmission entities 105-c, each of which may be an example of an intelligent radio head, or a transmit / receive (TRP) part. In some configurations, several functions of each access network entity or base station. 105 can be distributed across multiple network devices (e.g., radio heads and network access controllers) or consolidated into a single network device (e.g., a 105 base station). Petition 870240096014, dated 08 / 11 / 2024, page 25 / 178 21 / 81

[0060] One or more of the network devices 105 may include a base station capacity and coverage manager 101, which may receive an indication of a target UE capacity, where the target UE capacity may be specified by a service provider to distribute broadcast or multicast content and associated with a radio interface between the network device 105 and a UE 115. In some cases, the base station capacity and coverage manager 101 may configure the radio interface based on the indication received of the target UE capacity and transmit the broadcast or multicast content to the UE using the configured radio interface.

[0061] UEs 115 may include a UE 102 capacity and coverage manager, which may receive an indication of a target UE capacity to distribute broadcast or multicast content and associated with a radio interface between the UE 115 and a base station 105. In some examples, the UE 102 capacity and coverage manager may identify a supported UE 115 capacity and receive broadcast or multicast content using the radio interface based on an identified supported UE 115 capacity and the target UE capacity.

[0062] The 100 wireless communications system can be a packet-based network that operates according to a layered protocol stack. At the user plane, communications at the Packet Data Convergence Protocol (PDCP) layer may be IP-based. A radio link control (RLC) layer may, in some cases, perform packet segmentation and reassembly to communicate through logical channels. A control layer Petition 870240096014, dated 08 / 11 / 2024, page 26 / 178 The 22 / 81 medium access control (MAC) layer can perform priority handling and multiplexing of logical channels on transport channels. The MAC layer can also utilize Hybrid Automatic Repeat Request (HARQ) to provide retransmission at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can establish, configure, and maintain an RRC connection between a UE115 and a network device, such as a base station105 (or component of a base station105), or a core network130 supporting radio carriers for user plane data. In the physical layer (PHY), transport channels can be mapped to physical channels.

[0063] The 100 wireless communication system may include an RLC layer that connects the upper layers (e.g., RRC and PDCP) to the lower layers (e.g., the MAC layer). The RLC layer may be located between the PDCP layer and the MAC layer in the user plane protocol stack. The RLC layer may perform segmentation and reassembly of upper-layer packets in order to adapt them to the size that can actually be transmitted through the radio interface. For radio carriers that benefit from error-free transmission, the RLC layer also performs retransmission to recover from packet losses. Additionally, the RLC layer may perform reordering to compensate for out-of-order reception due to the HARQ operation in the MAC layer. There may be one RLC entity defined per radio carrier.

[0064] In some wireless communication systems, a base station 105 can broadcast or multicast the Petition 870240096014, dated 08 / 11 / 2024, page 27 / 178 23 / 81 data for a UE 115. The wireless communications system 100 may include a BMSC, which may be a server set to evolved MBMS (eMBMS) or MBMS, configured to transmit multicast data files to the UE 115 via the base station 105 and an MBMS-GW. MBMS-BW may be a network entity used to send packets on the core network 130. That is, MBMS-GW may send packets to addresses configured for different ANCs 105 by an MME (e.g., via an MCE).

[0065] Broadcast or multicast data can be transmitted on a control channel using, for example, single-cell point-to-multipoint (SC-PTM) or eMBMS techniques. These techniques can allow a network to flexibly schedule resources and provide broadcast or multicast services, and can also allow UEs 115 (e.g., IoT devices or MTC devices) to receive services of interest without undue complexity or overhead. For example, SC-PTM can be associated with a smaller number of resources used for communication in certain geographic areas (e.g., compared to single-frequency multicast-to-multicast (MBSFN) network transmissions), flexible resource allocation (e.g., due to dynamic scheduling), and can be frequency-domain multiplexed with unicast transmissions for improved spectral efficiency.Additionally, with SC-PTM, a broadcast area can be dynamically adjusted to fit a geographic area for specific services (e.g., group calls) without pre-establishing MBMS support through a predefined geographic area. Petition 870240096014, dated 08 / 11 / 2024, page 28 / 178 24 / 81

[0066] Within the 100 wireless communications system, eMBMS or SC-PTM services may be associated with or identified by a TMGI. For example, a server within the 130 core network may provide a TMGI to identify an eMBMS or SC-PTM session within the 100 wireless communications system. A TMGI may be a combination of a network or system identity, such as a public terrestrial mobile network (PLMN), and a service identity.

[0067] UEs 115 in the wireless communication system can be associated with various UE categories that represent the capabilities of a UE 115, where a UE category can define a combined uplink or downlink capability of the UE 115. For example, a UE capability might indicate a maximum transport block size (e.g., multiple bits supported) and / or bandwidth supported by the UE 115. In some cases, the UE 115 can communicate its capability to the network via RRC signaling or non-access stratum (NAS) to ensure that downlink transmissions are supported by the UE 115. For example, the UE 115 might transmit a UE capability information message to core network 130 when the UE 115 initially registers with core network 130. Downlink transmissions to the UE 115 by an ANC 105 can be based on respective UE categories for different UEs 115.

[0068] The wireless communications system 100 can support determining the capabilities of UE 115, such as category or coverage level for broadcast or multicast content (e.g., content delivered using MBMS). Generally, the techniques described provide the configuration of a radio interface to compensate for a Petition 870240096014, dated 08 / 11 / 2024, page 29 / 178 25 / 81 indicated capacity of a target UE 115. For example, a base station may receive an indication of a capacity of a particular target UE 115. The capacity of the target UE 115 may be specified by a service provider to distribute MBMS content, and subsequently associated with a radio interface between the base station and the target UE 115. The radio interface can then be configured based on the indicated capacity of the target UE 115, for example, by configuring a transport block size or bandwidth. The base station can then transmit broadcast or multicast content to the UE 115 using the configured radio interface.

[0069] Figure 2 illustrates an example of a wireless communications system 200 that supports the determination of capacity and coverage for multimedia broadcast and multicast services according to aspects of the present description. The wireless communications system 200 may include base station 105-a and one or more UEs 115 which may be examples of the corresponding devices as described with reference to Figure 1. UE 115-a and UE 115-b may be examples of different types of NBIoT devices, or different types of eMTC devices. UE 115-a and UE 115-b may receive data from base station 105-a via communication links 125-a and 125-b, respectively. The wireless communications system 200 may additionally include a service provider 205 (i.e., a content provider), a BMSC 210 and an MBMS access circuit (MBMS-GW) 215, or a combination thereof. In some examples, the 200 wireless communications system can support data broadcasting or multicasting. Petition 870240096014, dated 08 / 11 / 2024, p. 30 / 178 26 / 81

[0070] Service provider 205 can communicate with BMSC 210 to negotiate quality of service (QoS) requirements, for example, to broadcast multimedia content (e.g., a video sequence). QoS requirements may include metrics such as delay, error rate, and a maximum bit rate that can be supported. BMSC 210 can then configure an MBMS service (e.g., an MBMS support service) with base station 105-a via MBMS-GW 215. BMSC 210 can send the negotiated QoS requirements to base station 105-a via MBMS-GW 215, and, based on the received QoS requirements, base station 105-a can then apply a radio configuration to a radio interface with one or more UEs 115. The radio configuration may include, for example, a modulation and coding scheme (MCS) including a modulation order and a code rate that may describe the data rate of information for transmission.If, for example, a higher data rate is reported, a relatively larger MCS scheme can be used. However, if higher reliability is preferred, a relatively smaller MCS scheme can be used.

[0071] In MBMS, different UE115s (e.g., IoT or MTC devices) may have different capabilities, for example, supporting a larger TB size or a larger bandwidth (e.g., compared to the TB size of bandwidth that other UE115s may support). A UE115 may belong to a particular category, where the category may include other UE115s possessing similar capabilities. For example, where UE115 is an NB-IoT device, the NB-IoT device may Petition 870240096014, dated 08 / 11 / 2024, p. 31 / 178 27 / 81 belongs to a category of categories that define a maximum TB size (for example, a first category N1 might define a maximum TB size of 680 bits, a second category N2 might define a maximum TB size of 2,536 bits, and a third category might define a maximum TB size of 1,352 bits). In another example, where the UE 115 is an eMTC device, the MTC device might belong to a category that can define a bandwidth and a maximum TB size (for example, a first category M1 might define a bandwidth of 1.4 MHz and a maximum TB size of 1,000 bits, a second category M2 might define a bandwidth of 5 MHz and a maximum TB size of 4,008 bits, and a third category M3 can define a bandwidth of 20 MHz and a maximum TB size of 31,704 bits). BMSC 210 can establish an SCP™ configuration with a UE 115 when the UE 115 is in a connected mode (that is, when the UE 115 can send and receive data), according to the category in which the UE 115 capabilities are supported.

[0072] However, when another UE 115 is added to the field, the UE 115 may have different functionality than the UEs already connected 115. In this situation, the service provider 205 may inform the base station 105-a, via BMSC 210 and MBMS-GW 215, of a configuration including a category that supports the capabilities of the new UE 115. Thus, a method to efficiently optimize radio resources for a UE 115 that has not yet established a connection with a corresponding BMSC 210 may be desirable.

[0073] To indicate the corresponding category Petition 870240096014, dated 08 / 11 / 2024, p. 32 / 178 28 / 81 to the capabilities of an EU 115, the service provider 205 may first determine a respective category for the EU 115. The service provider 205 may know a type of EU 115 towards which the service provider's services 205 are targeted (for example, for UEs 115-a for a metering service, for UEs 115-b which are smartwatches, etc.), in which case the 205 service provider may determine the corresponding UE 115 category. Additionally or alternatively, the 205 service provider may determine the UE category. 115 based on the signaling on top of UE 115. That is, UE 115 can directly signal to service provider 205 the category corresponding to UE 115 capabilities. After determining the category corresponding to UE 115 capabilities, service provider 205 can transmit information including the category to base station 105-a via BMSC 210 and MBMS-GW 215. Based on the information received from service provider 205 via BMSC 210 and MBMS-GW 215, base station 105-a can determine the parameters for communication with UE 115 corresponding to the capabilities of UE 115 including, for example, a bandwidth and a maximum size in TB.

[0074] In a first technique for establishing a category to be used for a UE 115, the 205 service provider can explicitly indicate to BMSC 210 the category for BMSC 210 to use for a radio interface with the UE 115. When MBMS starts, the category can be indicated in a field on an interface between the 205 service provider and BMSC 210. The indicated category can indicate a maximum category to be used. That is, while the Petition 870240096014, dated 08 / 11 / 2024, page 33 / 178 The indicated category 29 / 81 may specify a category that supports a relatively larger maximum TB size; a category that supports a relatively smaller maximum TB size may still be used. For example, if an M2 category (defining, for example, a maximum TB size of 4,008 bits) is specified, an M1 category (defining, for example, a maximum TB size of 1,000 bits) may be used. The category may be included in the QoS requirements, as may have been negotiated between service provider 205 and MBSC 210. The indicated category may, however, be eliminated by BMSC 210, or BMSC 210 may reject the requirements. QoS, if BMSC 210 determines that another category might be more suitable. Alternatively, the interface between service provider 205 and BMSC 210 may not provide a category to be used. In that case, BMSC 210 may, on its own, determine a category to be used for a radio interface between BMSC 210 and UE 115.

[0075] Alternatively, in a second technique for establishing a category to be used for a UE 115, the category can be implicitly determined from the signaling of BMSC 210 to base station 105-a. In this case, a range of service identifiers (e.g., TMGIs) can be reserved for a particular category, and BMSC 210 can determine a corresponding service identifier based on the category to be used. BMSC 210 can then transmit the determined service identifier to base station 105-a via MBMS-GW 215. After receiving the service identifier from BMSC 210, base station 105-a can then determine parameters for communication with the UE 115 corresponding to the capabilities. Petition 870240096014, dated 08 / 11 / 2024, p. 34 / 178 30 / 81 of UE 115 including, for example, a maximum bandwidth and a maximum TB size. Alternatively, instead of determining the parameters for communication with UE 115 based on a service identifier, there may be a mapping between the negotiated QoS (e.g., using the QoS Class Identifier (QCI)) and the maximum bandwidth and TB size corresponding to the capabilities of UE 115. The QoS (e.g., a QCI) can thus be determined for a UE or a category of UEs capable of using a given bandwidth, or maximum bandwidth. In other examples, a given QoS (e.g., a QCI) can be associated with a UE or a category of UEs using a given TB size, or maximum TB size. In further examples, the QoS (or QCI) can be associated with a UE or group of UEs with capabilities associated with a given combination of bandwidths and TB size (or maximum value thereof).Thus, in some examples, BMSC can define. QCI such that CQI is a carrier-defined CQI, for example, a non-standard value that may be pre-arranged between the carrier and the service provider 205.

[0076] The capabilities of a UE 115 can be indicated in a USD in a transmission, in an SC-MCCH, or in a SIB. That is, USD can contain an indication of a maximum capacity, or an actual capacity, of the UE 115, as it can be received via MBMS or another broadcast channel. For example, a service identifier (e.g., a TMGI) included in a transmission from a BMSC 210 to the UE 115 might include a field for a category that indicates a maximum capacity for the UE 115s of that category. Then, if the Petition 870240096014, dated 08 / 11 / 2024, p. 35 / 178 31 / 81 If UE 115 supports the category indicated in the received transmission, the UE 115 can successfully receive the transmission. Alternatively, USD can be transmitted using a standard or pre-configured service identifier (e.g., a TMGI) indicating a reference category corresponding to a minimum UE 115 capacity (e.g., for an NB-IoT device, a TMGI X, for an eMTC device, a TMGI Y, where each of TMGI X and TMGI Y may correspond to a relatively small minimum TB size). Additionally or alternatively, a maximum capacity, or a reference capacity, of a UE 115 can be transmitted in the radio access network (RAN) signaling, such as in an SC-MCCH or a SIB. The received maximum capacity or reference capacity can then be used to determine a downlink control information (DCI) format.

[0077] In some cases, different UEs 115 in a multi-UE 115 deployment may utilize different levels of coverage enhancement. For example, a software update for a UE 115 that may be subject to greater path loss (e.g., UE 115-a for a metering service in a basement) may utilize a relatively greater coverage enhancement, whereas a software update for a UE 115 that may be subject to less path loss (e.g., for audio sequencing services for UE 115-b which is a smartwatch) may utilize a relatively smaller coverage enhancement. The service provider 205 may, accordingly, indicate to BMSC 210 an expected coverage enhancement for the services, for example, in Petition 870240096014, dated 08 / 11 / 2024, page 36 / 178 32 / 81 QoS requirements. For example, based on a known type of typical target UT 115, service provider 205 can transmit a signal with a coverage enhancement level selected from the set {c0, c1, c2, c3}, where c0 can represent no coverage enhancement, c1 can represent a small coverage enhancement, c2 can represent a medium coverage enhancement, and c3 can represent a large coverage enhancement, each representing, for example, a dB value.

[0078] Additionally or alternatively, BMSC 210 can set a target for a successful reception level and adjust the coverage enhancement level to achieve the determined target based on responses received from UEs 115. For example, BMSC 210 can set a target of 99% service reception. After announcing the service, each UE 115 communicating with BMSC 210 can report to BMSC 210 whether UE 115 received the service. If BMSC 210 determines that the target level of successful reception was not met, BMSC 210 can then increase its coverage enhancement level to try to achieve its target level of successful reception. Service provider 205 can similarly apply this technique to adjust the coverage enhancement level to QoS requirements based on BMSC 210 reporting a successful reception level to service provider 205.For example, if BMSC 210 determines that the target level of successful reception was not matched, BMSC 210 can relay this information to service provider 205, and service provider 205 can then increase the coverage enhancement level in the QoS requirements (e.g., from c1 to...). Petition 870240096014, dated 08 / 11 / 2024, page 37 / 178 33 / 81 C2).

[0079] Figure 3 illustrates an example of a 300 process flow in a wireless communications system that supports the determination of Capacity and Coverage for multimedia broadcast and multicast services, according to aspects of the present description. The 300 process flow includes UE 115-cea base station 105-b, which may be respective examples of a UE 115 and a base station 105, as described with reference to Figures 1 and 2. The 300 process flow additionally includes service provider 205-ae BMSC 210-a, which may be respective examples of a service provider 205 and a BMSC 210, as described with reference to Figure 2. The 300 process flow may be an example of identifying and transmitting an indication of a UE capacity and, accordingly, transmitting MBMS content based on the UE capacity.

[0080] In 305, UE 115-c can optionally transmit to service provider 205-a, and service provider 205-a can receive from UE 115-c, a request for MBMS content. UE 115-c can additionally indicate in the MBMS content request a category corresponding to the capabilities of UE 115-c, where the category can define parameters (e.g., a bandwidth and maximum TB size) for UE 115s possessing capabilities similar to UE 115-c. The content request can be transmitted via over-the-top signaling from UE 115-c to service provider 205-a. That is, UE 115-c can directly signal to service provider 205-a the category corresponding to the capabilities of UE 115-c.

[0081] In 310, service provider 205-a can Petition 870240096014, dated 08 / 11 / 2024, page 38 / 178 34 / 81 determine a target EU capacity for EU 115-c. The 205-a service provider can determine the capacity based on a category to which the EU 115-c belongs. To determine the capacity, or category that defines a corresponding capacity, the 205-a service provider may already know a type of EU 115 to which the 205-a service provider's services are focused (e.g., for EU 115s for a metering service, for EU 115s that are smartwatches, etc.) and to which the EU 115-c belongs. In that case, the 205-a service provider can determine the category of the EU 115-c accordingly. Additionally or alternatively, the 205-c service provider may determine the UE 115-c category based on the signaling on top from UE 115-c, for example, the request for MBMS content (e.g., via the request sent in 305).

[0082] In 315, service provider 205-a can transmit to BMSC 210-a, and BMSC 210-a can receive from service provider 205-a, an indication of the target UE capacity. The UE 115-c capacity display can be included in a USD, SC-MCCH, or SIB within the transmission.

[0083] In 320, BMSC 210-a can transmit to base station 105-b, and base station 105-b can receive from BMSC 210-a, a capacity indication for target UE 115c. Additionally or alternatively, the capacity indication can be transmitted and received through a network node, where the network node can be, for example, an MBMSGW, or BMSC 210-a as described above. In some cases, the capacity may have been specified by the service provider 205-a for MBMS content distribution. The indication may additionally include a category. Petition 870240096014, dated 08 / 11 / 2024, p. 39 / 178 35 / 81 corresponding to UE 115-c. In some examples, the category may correspond to a set of UE 115s possessing similar capabilities. For example, UE 115-c may be an example of an NB-IoT device, and the NB-IoT device may belong to a category that defines a maximum TB size. Alternatively, where UE 115-c is an eMTC device, the MTC device may belong to a category that may define a bandwidth and a maximum TB size. Alternatively, the capability indication may include one or more TMGIs (i.e., service identifiers), where TMGIs may implicitly indicate the category to which UE 115-c belongs.

[0084] In 325, base station 105-b can identify a target UE capacity 115-c. In one case, the capacity can be identified based on an explicit indication received from service provider 205-a via BMSC 210-c or MBMS-GW. For example, UE capacity 115-c can be identified based on an indicated category to which UE 115-c belongs. Alternatively, the category can be implicitly determined from signaling from a network node (e.g., BMSC 210, or MBMSGW) to base station 105-b. In this case, a range of TMGIs (i.e., service identifiers) can be reserved for a particular category, and BMSC 210-a can have determined a corresponding service identifier based on the category that corresponds to UE 115-c. After receiving the service identifier, the 105-b base station can then identify the parameters for communication with the UE 115-c, corresponding to the capabilities of the UE 115-c.Alternatively, instead of determining the parameters... Petition 870240096014, dated 08 / 11 / 2024, p. 40 / 178 36 / 81 for communication with UE 115 based on a service identifier, there may be a mapping between the negotiated QoS (e.g., using a QCI) and the maximum bandwidth and TB size corresponding to the capabilities of UE 115-c. Base station 105-b can use the identified capacity to configure, accordingly, a radio interface between base station 105-b and UE 115-c.

[0085] In 330, base station 105-b can transmit to UE 115-c, and UE 115-c can receive from base station 105-b, an indication of a target UE capability (e.g., a capability of UE 115-c). The target UE capability may have been specified by the service provider. 205-a to distribute MBMS content. The capacity can then be associated with and used to configure a radio interface between UE 115-cea and base station 105-b. In some cases, the indication may be based on a minimum supported capacity of UE 115-c. In other cases, the indication may be based on a maximum supported capacity of a target UE (e.g., UE 115-c), or an actual supported capacity of the target UE. The indication may include a category corresponding to UE 115-c, where the category may correspond to a set of UE 115s possessing similar capabilities. The category may define parameters including, for example, a bandwidth and a maximum TB size. The capacity, or corresponding category, may be indicated in a USC, SC-MCCH, or SIB within the transmission.Based on receiving, for example, USD, EU 115-c can then monitor MBMS content (e.g., content broadcasting or multi-broadcasting), such as EU 115-c can receive, for example, in 355. The capacity can be... Petition 870240096014, dated 08 / 11 / 2024, page 41 / 178 37 / 81 is additionally used to determine a DCI format. In this case, UE 115-c can, accordingly, monitor a DCI format based on SC-MCCH.

[0086] On 335, base station 105-b can configure a radio interface based on the indicated capacity of the target UE 115-c received from service provider 205-a via BMSC 210-ae an MBMS-GW. On 340, UE 115c can identify a supported UE 115-c capacity based on the indicated capacity of UE 115-c received on 330. The capacity can be included in a category, where the category can define a bandwidth and a maximum TB size supported by UEs in the category to which UE 115-c corresponds. UE 115-c can further determine if the supported capacity is compatible with UE 115-c capabilities. If the supported capacity is compatible with the UE 115-c capabilities, UE 115-c can then monitor MBMS content (e.g., broadcast or multicast content), which UE 115-c can receive, for example, on 355.

[0087] In 345, service provider 205-a can transmit to BMSC 210-a, and BMSC 210-a can receive from service provider 205-a, broadcast or multicast content (such as MBMS content). In 350, BMSC 210-a can transmit to base station 105-b, and base station 105b can receive MBMS content from BMSC 210-a. Additionally or alternatively, MBMS content can be transmitted and received through a network node, where the network node can be, for example, an MBMS-GW or BMSC 210-a as mentioned. In 355, base station 105-b can transmit to UE 115c, and UE 115-c can receive content from base station 105-b. Petition 870240096014, dated 08 / 11 / 2024, p. 42 / 178 38 / 81 MBMS using the previously configured radio interface based on the identified supported capability of UE 115-c.

[0088] Figure 4 illustrates an example of a 400 process flow in a wireless communications system that supports the determination of capacity and coverage for multimedia broadcast and multicast services according to aspects of the present description. The 400 process flow includes UE 115-c and base station 105-c, which may be respective examples of a UE 115 and a base station 105 as described with reference to Figures 1 and 2. The 400 process flow additionally includes service provider 205-b and BMSC 210-b, which may be respective examples of a service provider 205 and a BMSC 210, as described with reference to Figure 2. The 400 process flow may be an example of identifying and adjusting a coverage enhancement level for a UE.

[0089] In 405, the 205-b service provider may determine a coverage enhancement level (i.e., an expected coverage level) expected to provide the desired coverage enhancement for one or more connected UEs, including, for example, UE 115-d.

[0090] In 410, service provider 205-b can transmit to BMSC 210-b, and BMSC 210-b can receive from service provider 205-b, an indication specifying the coverage enhancement level determined in 405. Different UEs 115 in a multi-UE 115 deployment may utilize different coverage enhancement levels. For example, a software update to a UE 115 that may be subject to greater path loss (e.g., a UE 115 for a metering service in a Petition 870240096014, dated 08 / 11 / 2024, page 43 / 178 39 / 81 basement) may utilize a relatively larger coverage enhancement, whereas a software update for a UE 115, which may be subject to less path loss (e.g., for audio sequencing services for a UE 115 that is a smartwatch) may utilize a relatively small coverage enhancement. The 205-b service provider may, accordingly, indicate to BMSC 210 an expected coverage enhancement for the services, for example, in QoS requirements.Based on a known type of typical target UE 115 (e.g., UE 115-d), service provider 205-b can transmit a signal with a coverage enhancement level selected from the set {c0, c1, c2, c3}, where c0 can represent no coverage enhancement, c1 can represent a small coverage enhancement, c2 can represent a medium coverage enhancement, and c3 can represent a large coverage enhancement, each representing, for example, a dB value.

[0091] In 415, BMSC 210-b can transmit to base station 105-c, and base station 105-c can receive from BMSC 210-b, an indication specifying the determined coverage enhancement level. Additionally or alternatively, the indication specifying the determined coverage enhancement level can be transmitted and received through a network node, where the network node can be, for example, an MBMS-GW or BMSC 210-b, as mentioned.

[0092] On 420, base station 105-c can identify a level of coverage enhancement. The level of coverage enhancement identified can be Petition 870240096014, dated 08 / 11 / 2024, page 44 / 178 40 / 81 identified based on the coverage enhancement level determined by service provider 205-b on 405. On 425, base station 105-c can transmit to UE 115-d and UE 115-d can receive from base station 105-c an indication of a target UE capacity including the determined coverage enhancement level.

[0093] In 430, base station 105-c can configure a radio interface based on the received indication of the expected coverage level. An indication of UE 115-d capability may include the indication of the expected coverage level. In 435, service provider 205-b can transmit to BMSC 210-b, and BMSC 210-b can receive from service provider 205-b, broadcast or multicast content (such as MBMS content).

[0094] On 440, BMSC 210-b can transmit to base station 105-c, and base station 105-c can receive MBMS content from BMSC 210-b. Additionally or alternatively, MBMS content can be transmitted and received through a network node, where the network node can be, for example, an MBMS-GW or BMSC 210-b, as mentioned.

[0095] On 445, base station 105-c can transmit to UE 115-d, and UE 115-d can receive MBMS content from base station 105-c using the radio interface previously configured based on the identified coverage enhancement level. On 450, UE 115d can transmit to base station 105-c, and base station 105-c can receive a report from UE 115-d indicating whether UE 115-d successfully received the transmitted MBMS content. Base station 105-c can receive multiple such reports from UEs. Petition 870240096014, dated 08 / 11 / 2024, p. 45 / 178 41 / 81

[0096] In 455, base station 105-c can transmit to BMSC 210-b, and BMSC 210-b can receive from base station 105-c a report indicating whether UE 115-d successfully received the transmitted MBMS content. Additionally or alternatively, the report indicating whether UEs successfully received the transmitted MBMS content can be transmitted or received via a network node, where the network node can be, for example, an MBMS-GW, or BMSC 210-b as mentioned. BMSC 210-b can receive one or more of these reports from multiple UEs, from which BMSC 210-b can determine a proportion of the total number of UEs that successfully received the transmitted MBMS content.

[0097] In 460, BMSC 210-b can determine an updated coverage enhancement level based on one or more received reports indicating whether UEs 115 (including, for example, UE 115-d) successfully received the transmitted MBMS content. In some cases, BMSC 210-b may have a target set for a successful reception level and adjust the coverage enhancement level to achieve the determined target based on the responses received from UEs 115. For example, BMSC 210-b may set a target of 99% service reception. After announcing the service, each UE 115 in communication with BMSC 210-b can report to BMSC 210-b whether UE 115 received the service. Based on the reports, BMSC 210-b can determine an updated coverage enhancement level to enable the respective 115 UEs to successfully receive MBMS content at the desired rate.If BMSC 210 determines that the target level of successful reception has not been met, BMSC 210 may then increase its coverage enhancement level. Petition 870240096014, dated 08 / 11 / 2024, page 46 / 178 42 / 81 to try to achieve its target level of successful reception.

[0098] While 460 discusses determining an updated coverage level additionally or alternatively, BMSC 210 may modify other radio access parameters based on one or more reports received indicating whether the UEs 115 (including, for example, UE 115-d) successfully received the transmitted MBMS content. BMSC 210-b can determine, accordingly, other parameters based on the capabilities of the UE 115 response units. For example, in addition to modifying the coverage enhancement level, BMSC 210 can modify a category for a UE 115, a maximum bandwidth, or a maximum TB size.

[0099] In 465, BMSC 210-b can transmit to base station 105-c, and base station 105-c can receive from BMSC 210-b, an updated indication specifying the updated coverage enhancement level determined in 460. Additionally or alternatively, the updated indication specifying the updated coverage enhancement level can be transmitted and received through a network node, where the network node can be, for example, an MBMS-GW, or BMSC 210-b, as mentioned. Additionally, as discussed with reference to 460, BMSC 210-b can further transmit an updated indication of parameters including, for example, a category for a UE 115, a maximum bandwidth, or a maximum TB size.

[0100] On 470, base station 105-c can modify the radio interface based on the updated indication received of the updated coverage enhancement level. Base station 105-c can modify Petition 870240096014, dated 08 / 11 / 2024, page 47 / 178 43 / 81 additionally the radio interface based on the updated parameters received in the updated indication on 465, including, for example, a category for a UE 115, a maximum bandwidth, or a maximum TB size. The base station 105-c can then use the modified radio interface to transmit MBMS data to one or more UEs, including, for example, UE 115-d. This process can be iterated, thus providing repeated adjustments of the coverage enhancement level, until the desired ratio of connected UEs has successfully received MBMS data.

The terms system and network are often used interchangeably. A CDMA system can implement a radio technology such as CDMA2000, Universal Terrestrial Radio Access (UTRA), etc. CDMA2000 covers the IS-2000, IS-95, and IS-856 standards. IS-2000 versions may be commonly referred to as CDMA2000 1X, 1X, etc. IS-856 (TIA-856) is commonly referred to as CDMA2000 1xEV-DO, Packet Data in High Rate Digital Radio (HRPD), etc. UTRA includes Wideband CDMA (WCDMA) and other variations of CDMA. A TDMA system may implement a radio technology such as the Global System for Mobile Communications (GSM).

[0176] An OFDMA system can implement a radio technology such as Ultra Mobile Broadband (UMB), Evolved UTRA (E-UTRA), Institute of Electrical and Electronics Engineers (IEEE) 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, Flash-OFDM, etc. UTRA and E-UTRA are part of the Universal Mobile Telecommunications System (UMTS). 3GPP LTE and LTE-A are versions of UMTS that utilize E-UTRA. UTRA, E-UTRA, UMTS, LTE, LTE-A, NR, and GSM are described in documents from an organization called the 3rd Generation Partnership Project (3GPP). CDMA2000 and UMB are described in documents from an organization called the 3rd Generation Partnership Project 2 (3GPP2). The techniques described here can be used for the radio systems and technologies mentioned above, as well as other radio systems and technologies. While aspects of an LTE system or an NR system may be described for illustrative purposes, and the terminology LTE or NR may be used throughout much of the description, the Petition 870240096014, dated 08 / 11 / 2024, pp. 78 / 178 74 / 81 techniques described here are applicable beyond LTE or NR applications.

[0177] In LTE / LTE-A networks, including such networks described herein, the term evolved B node (eNB) can generally be used to describe base stations. The wireless communications system or systems described herein may include an LTE / LTE-A or NR network in which different types of evolved B nodes (eNBs) provide coverage for various geographic regions. For example, each eNB, gNB, or base station may provide communication coverage for a macro cell, a small cell, or other cell types. The term cell can be used to describe a base station, a carrier or component carrier associated with a base station, or a coverage area (e.g., sector, etc.) of a carrier or base station, depending on the context.

[0178] Base stations may include, or may be referred to by those skilled in the art as, a base transceiver station, a radio base station, an access point, a radio transceiver, a B Node, eNodeB (eNB), next-generation B Node (gNB), household B Node, a household eNodeB, or some other suitable terminology. The geographic coverage area for a base station may be divided into sectors creating only a portion of the coverage area. The wireless communications system or systems described herein may include base stations of different types (e.g., macro-cell or small-cell base stations). The UEs described herein may communicate with various types of base stations and network equipment including macro eNBs, small-cell eNBs, gNBs, relay base stations, and the like. There may be geographic coverage areas. Petition 870240096014, dated 08 / 11 / 2024, page 79 / 178 75 / 81 overlapping for different technologies.

[0179] A macro cell typically covers a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs with service subscriptions with the network provider. A small cell is a low-power base station, compared to a macro cell, that may operate in the same or different radio frequency spectrum bands (e.g., licensed, unlicensed, etc.) as macro cells. Small cells may include pico cells, femto cells, and micro cells according to various examples. A pico cell, for example, may cover a small geographic area and may allow unrestricted access by UEs with service subscriptions with the network provider.A femtocell can also cover a small geographic area (e.g., a residence) and can provide restricted access by UEs possessing an association with the femtocell (e.g., UEs in a closed subscriber group (CSG), UEs for users in the residence, and similar). An eNB for a macrocell can be referred to as a macro eNB. An eNB for a small cell can be referred to as a small-cell eNB, a pico eNB, a femto eNB, or a home eNB. An eNB can support one or multiple cells (e.g., two, three, four, and similar) (e.g., component carriers).

[0180] The wireless communication system or systems described herein may support synchronized or asynchronous operation. For synchronized operation, base stations may exhibit similar frame timing, and transmissions from different base stations may be Petition 870240096014, dated 08 / 11 / 2024, page 80 / 178 76 / 81 approximately time-aligned. For asynchronous operation, base stations may have different frame timings, and transmissions from different base stations may not be time-aligned. The techniques described here can be used for synchronized or asynchronous operations.

[0181] The downlink transmissions described herein may also be called forward link transmissions, while the uplink transmissions may also be called reverse link transmissions. Each communication link described herein, including, for example, the 100 and 200 wireless communication systems as described with reference to Figures 1 and 2, may include one or more carriers, where each carrier may be a signal made up of multiple subcarriers (e.g., waveform signals of different frequencies).

[0182] The description presented here, with respect to the attached drawings, describes illustrative configurations and does not represent all examples that can be implemented or that are within the scope of the claims. The term illustrative used here means serving as an example, case, or illustration and not preferred or advantageous over other examples.

A general-purpose processor may be a microprocessor, but alternatively, the processor may be any conventional processor, controller, microcontroller, or state machine. A processor may also Petition 870240096014, dated 08 / 11 / 2024, page 82 / 178 78 / 81 can be implemented as a combination of computing devices (for example, a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors together with a DSP core, or any other configuration).

[0186] The functions described herein may be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software executed by a processor, the functions may be stored in or transmitted as one or more instructions or code in a computer-readable medium. Other examples and implementations are within the scope and spirit of the appended description and claims. For example, due to the software nature, functions described above may be implemented using software executed by a processor, hardware, firmware, wiring, or combinations thereof.The feature implementation functions may be physically located in various positions, including those used herein, including in the claims, the term and / or, when used in a list of two or more items, means that any one of the listed items may be employed alone, or any combination of two or more of the listed items may be employed. For example, if a composition is described as containing components A, B, and / or C, the composition may contain A only; B only; C only; A and B in combination; A and C in combination; B and C in combination; or A, B, and C in combination. Furthermore, as used here, including in claims, or as used in a list of items (for example, a list of items inserted by a phrase). Petition 870240096014, dated 08 / 11 / 2024, p. 83 / 178 79 / 81 such as at least one among or one or more among) indicates an inclusive list so that, for example, a phrase referring to at least one among a list of items refers to any combination of those items, including single elements. As an example, at least one among: A, B or C must cover A, B, C, AB, AC, BC and ABC, plus any combination with multiples of the same element (e.g. AA, AAA, AAB, AAC, ABB, AC-C, BB, BBB, BBC, CC and CCC or any other ordering of A, B, C).

[0187] As used herein, the phrase based on should not be considered as a reference to a closed set of conditions. For example, an illustrative step that is described as based on condition A may be based on both condition A and condition B without departing from the scope of the present description. In other words, as used herein, the phrase based on should be considered in the same way as the phrase based at least in part on.

[0188] Computer-readable media includes both non-transient computer storage media and communication media, including any means that facilitate the transfer of a computer program from one place to another. Non-transient storage media may be any available media that can be accessed by a general-purpose or special-purpose computer. By way of example, and not limitation, non-transient computer-readable media may comprise RAM, ROM, electrically erasable programmable read-only memory (EEPROM), compact disc (CD) ROM, or other disk storage.
