Description

[0001] This application is a divisional application of the application filed on January 31, 2019, with application number 201980011339.2 and entitled "Carrier Capability Signaling for Multiple Carrier Digital Schemes".

[0002] Based on the cross-reference to relevant applications in 35 U.S.SC § 119

[0003] This application claims priority to the following applications: U.S. Provisional Patent Application No. 62 / 625,805, filed February 2, 2018, entitled “TECHNIQUES AND APPARATUSES FOR CARRIER CAPABILITY SIGNALING WITH REGARD TO MULTIPLE CARRIER NUMEROLOGIES”; and U.S. Non-Provisional Patent Application No. 16 / 262,432, filed January 30, 2019, entitled “CARRIER CAPABILITY SIGNALING WITH REGARD TO MULTIPLE CARRIER NUMEROLOGIES”, all of which are expressly incorporated herein by reference. Technical Field

[0004] In general, aspects of this disclosure relate to wireless communications, and more specifically, aspects of this disclosure relate to techniques and apparatus for carrier capability signaling with respect to a multi-carrier digital scheme. Background Technology

[0005] Wireless communication systems are widely deployed to provide a variety of telecommunications services such as telephone, video, data, messaging, and broadcasting. Typical wireless communication systems employ multiple access technologies that enable communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access (SC-FDMA) systems, Time Division Synchronous Code Division Multiple Access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE / Improved LTE is an enhanced set of the Universal Mobile Telecommunications System (UMTS) mobile standard released by the 3rd Generation Partnership Project (3GPP).

[0006] Wireless communication networks may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). UEs can communicate with base stations (BSs) via downlinks and uplinks. A downlink (or forward link) refers to the communication link from the BS to the UE, while an uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, a BS may be referred to as a Node B, gNB, Access Point (AP), Radio Headend, Transmitter-Receiver Point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0007] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that enables different user equipment to communicate at the city, country, region, and even global levels. New Radio (NR) (also known as 5G) is an enhancement set of the LTE mobile standard released by the 3rd Generation Partnership Project (3GPP). NR is designed to better integrate with other open standards by improving spectrum efficiency, reducing costs, improving service, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also known as Discrete Fourier Transform Spread Spectrum OFDM (DFT-s-OFDM)) on the uplink (UL), thereby better supporting mobile broadband internet access, and supporting beamforming, multiple-input multiple-output (MIMO) antenna technologies and carrier aggregation. However, with the continued growth in demand for mobile broadband access, there is a need for further improvements to LTE and NR technologies. Preferably, these improvements should be applicable to other multiple access technologies and telecommunications standards that employ these technologies. Summary of the Invention

[0025] The various aspects of this disclosure are described more fully below with reference to the accompanying drawings. However, this disclosure may be embodied in many different forms and should not be construed as limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of this disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art will understand that the scope of this disclosure is intended to cover any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, an apparatus or a method may be implemented using any number of the aspects set forth herein. Furthermore, the scope of this disclosure is intended to cover such apparatuses or methods implemented using structures, functions, or structures and functions other than or different from the aspects of this disclosure set forth herein. It should be understood that any aspect of this disclosure disclosed herein may be embodied by one or more elements of the claims.

[0026] Several aspects of a telecommunications system will now be described with reference to various devices and techniques. These devices and techniques will be described in detail below and illustrated in the accompanying drawings, through various frames, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as “elements”). These elements can be implemented using hardware, software, or a combination thereof. Whether such an element is implemented as hardware or software depends on the specific application and the design constraints imposed on the entire system.

[0027] It should be noted that although this document may use terms commonly associated with 3G and / or 4G wireless technologies to describe aspects, aspects of this disclosure can be applied to communication systems based on other generations (e.g., 5G and later, including NR technologies).

[0028] Figure 1This diagram illustrates a network 100 in which various aspects of this disclosure may be implemented. Network 100 may be an LTE network or some other wireless network (e.g., a 5G or NR network). Wireless network 100 may include multiple BS 110s (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A BS is an entity that communicates with a user equipment (UE) and may also be referred to as a base station, NR BS, Node B, gNB, 5G Node B (NB), access point, Transmitter-Receiver Point (TRP), etc. Each BS can provide communication coverage for a specific geographic area. In 3GPP, the term "cell" may refer to the coverage area of ​​a BS and / or the BS subsystem serving that coverage area, depending on the context in which the term is used.

[0029] A BS can provide communication coverage for macrocells, picocells, femtocells, and / or another type of cell. A macrocell can cover a relatively large geographic area (e.g., a radius of several kilometers) and can allow unrestricted access by UEs with service subscriptions. A picocell can cover a relatively small geographic area and can allow unrestricted access by UEs with service subscriptions. A femtocell can cover a relatively small geographic area (e.g., a residential area) and can allow restricted access by UEs associated with that femtocell (e.g., UEs in a Closed User Group (CSG)). A BS used for macrocells can be referred to as a macro BS. A BS used for picocells can be referred to as a pico BS. A BS used for femtocells can be referred to as a femtocell BS or a home BS. Figure 1 In the examples shown, BS 110a can be a macro BS for macro cell 102a, BS 110b can be a pico BS for pico cell 102b, and BS 110c can be a femto BS for femto cell 102c. A BS can support one or more (e.g., three) cells. The terms “eNB,” “base station,” “NR BS,” “gNB,” “TRP,” “AP,” “Node B,” “5G NB,” and “cell” are used interchangeably herein.

[0030] In some respects, the cell may not be stationary, and the geographical area of ​​the cell may move depending on the location of the mobile BS. In some respects, BSs may interconnect with each other and / or with one or more other BSs or network nodes (not shown) in access network 100 via various types of backhaul interfaces (e.g., direct physical connection, virtual network, and / or similar interfaces using any suitable transport network).

[0031] The wireless network 100 may also include a relay station. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a BS or a UE) and transmit the data transmissions to a downstream station (e.g., a UE or a BS). A relay station can also be a UE capable of relaying transmissions for other UEs. Figure 1 In the example shown, relay station 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. A relay station can also be referred to as a relay BS, relay base station, repeater, etc.

[0032] Wireless network 100 can be a heterogeneous network comprising different types of Base Stations (BSs) (e.g., macro BSs, pico BSs, femto BSs, relay BSs, etc.). These different types of BSs can have different transmit power levels, different coverage areas, and different effects on interference in wireless network 100. For example, macro BSs can have high transmit power levels (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmit power levels (e.g., 0.1 to 2 watts).

[0033] Network controller 130 can be coupled to a group of base stations (BSs) and can provide coordination and control for these BSs. Network controller 130 can communicate with the BSs via backhaul. BSs can also communicate with each other directly or indirectly, for example, via wireless or wired backhaul.

[0034] UE 120 (e.g., 120a, 120b, 120c) may be distributed throughout the wireless network 100, and each UE may be stationary or mobile. UE may also be referred to as an access terminal, terminal, mobile station, user unit, station, etc. UE may be a cellular phone (e.g., a smartphone), personal digital assistant (PDA), wireless modem, wireless communication device, handheld device, laptop computer, cordless phone, wireless local loop (WLL) station, tablet device, camera, gaming device, netbook, smartbook, ultrabook, medical device or apparatus, biometric sensor / device, wearable device (e.g., smartwatch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet, etc.)), entertainment device (e.g., music or video device, satellite radio unit, etc.), vehicle component or sensor, smart meter / sensor, industrial manufacturing equipment, GPS device, or any other suitable device configured to communicate via wireless or wired media.

[0035] Some UEs can be considered Machine-Type Communication (MTC) or Evolved or Enhanced Machine-Type Communication (eMTC) UEs. MTC and eMTC UEs include, for example, robots, drones, remote devices, sensors, meters, monitors, location tags, etc., which can communicate with a base station, another device (e.g., a remote device), or some other entity. Wireless nodes can provide connectivity to or to a network (e.g., a wide area network such as the Internet or cellular networks) via wired or wireless communication links, for example. Some UEs can be considered Internet of Things (IoT) devices, and / or can be implemented as NB-IoT (Narrowband Internet of Things) devices. Some UEs can be considered Customer Premises Equipment (CPE). UE 120 can be included within a housing that houses the components of UE 120, such as processor components, memory components, etc.

[0036] Typically, any number of wireless networks can be deployed in a given geographical area. Each wireless network can support a specific RAT and can operate on one or more frequencies. A RAT can also be referred to as a radio technology, air interface, etc. A frequency can also be referred to as a carrier, channel, etc. Each frequency can support a single RAT in a given geographical area to avoid interference between wireless networks using different RATs. In some cases, NR or 5G RAT networks can be deployed.

[0037] In some respects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using BS 110 as an intermediary for communication with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, mesh networks, etc.). In this case, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described herein as being performed by BS 110.

[0038] As pointed out above, Figure 1 This is provided as an example only. Other examples may differ from those provided. Figure 1 The example described.

[0039] Figure 2 BS 110 and UE 120 are shown (they can be Figure 1The block diagram of design 200 (a base station in the base station and a UE in the UE) is shown. The base station 110 may be equipped with T antennas 234a to 234t, and the UE 120 may be equipped with R antennas 252a to 252r, wherein generally, T≥1 and R≥1.

[0040] At BS 110, the transmitting processor 220 can receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCS) for that UE based at least in part on the Channel Quality Indicator (CQI) received from each UE, process (e.g., code and modulate) the data for that UE based at least in part on the MCS selected for each UE, and provide data symbols for all UEs. The transmitting processor 220 can also process system information (e.g., semi-static resource allocation information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper-layer signaling, etc.), and provide overhead symbols and control symbols. The transmitting processor 220 can also generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS)) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 can perform spatial processing (e.g., precoding, if applicable) on data symbols, control symbols, overhead symbols, and / or reference symbols, and can provide T output symbol streams to T modulators (MODs) 232a to 232t. Each modulator 232 can (e.g., for OFDM, etc.) process its corresponding output symbol stream to obtain an output sample stream. Each modulator 232 can further process (e.g., convert to analog, amplify, filter, and up-convert) the output sample stream to obtain a downlink signal. The T downlink signals from modulators 232a to 232t can be transmitted via T antennas 234a to 234t respectively. According to the aspects described in more detail below, position coding can be used to generate synchronization signals to transmit additional information.

[0041] At UE 120, antennas 252a to 252r can receive downlink signals from BS 110 and / or other base stations, and can provide the received signals to demodulators (DEMODs) 254a to 254r respectively. Each demodulator 254 can adjust (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain an input sample. Each demodulator 254 can further process the input sample (e.g., for OFDM, etc.) to obtain received symbols. MIMO detector 256 can obtain received symbols from all R demodulators 254a to 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. Receiver processor 258 can process (e.g., demodulate and decode) the detected symbols, provide decoded data for UE 120 to data sink 260, and provide decoded control information and system information to controller / processor 280. The channel processor can determine the Received Reference Power (RSRP), Received Signal Strength Indicator (RSSI), Received Reference Quality (RSRQ), Channel Quality Indicator (CQI), etc.

[0042] On the uplink, at UE 120, the transmitting processor 264 can receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, CQI, etc.). The transmitting processor 264 can also generate reference symbols for one or more reference signals. Symbols from the transmitting processor 264 can be pre-encoded (if applicable) by TX MIMO processor 266, further processed by modulators 254a to 254r (e.g., for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to BS 110. At BS 110, uplink signals from UE 120 and other UEs can be received by antenna 234, processed by demodulator 232, detected by MIMO detector 236 (if applicable), and further processed by receiving processor 238 to obtain decoded data and control information transmitted by UE 120. The receiver processor 238 can provide decoded data to the data sink 239 and decoded control information to the controller / processor 240. The network controller 110 may include a communication unit 244 and communicates with the network controller 130 via the communication unit 244. The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292.

[0043] In some respects, one or more components of UE 120 may be included in the housing. This includes the controller / processor 240 of BS 110, the controller / processor 280 of UE 120, and / or Figure 2Any other components may perform one or more techniques associated with carrier capability signaling regarding multiple carrier digital schemes, as described in more detail elsewhere herein. For example, the controller / processor 240 of BS 110, the controller / processor 280 of UE 120, and / or Figure 2 Any other component can perform or direct, for example Figure 5 Process 500 Figure 6 The operation of process 600 and / or other processes as described herein. Memory 242 and 282 may store data and program code for BS 110 and UE 120, respectively. Scheduler 246 may schedule the UE for data transmission on the downlink and / or uplink.

[0044] In some aspects, UE 120 may include: a unit for determining the capabilities of UE 120 in relation to its carrier configuration; a unit for transmitting information identifying the capabilities; a unit for initiating a Multimedia Multicast Broadcast Service (MBMS) Receive-Only Mode (ROM) session; a unit for reattaching to the network associated with the base station; a unit for transmitting an interest indicator associated with the MBMS ROM session; a unit for initiating a tracking area update regarding the network in association with the MBMS ROM session; and so on. In some aspects, such a unit may include a combination of Figure 2 One or more components of the UE 120 described.

[0045] In some aspects, BS 110 may include: units for receiving information identifying the capabilities of a UE related to its carrier configuration; units for determining a configuration for communication with the UE based at least in part on the information identifying the capabilities; units for receiving an interest indicator associated with the UE's MBMS ROM session; units for receiving or obtaining information identifying at least two different digital schemes; and so on. In some aspects, such units may include combinations of... Figure 2 One or more components of the BS 110 described.

[0046] As pointed out above, Figure 2 This is provided as an example only. Other examples may differ from those provided. Figure 2 The example described.

[0047] The UE can communicate using two or more different digital schemes. A digital scheme can correspond to subcarrier spacing, symbol duration, and / or cyclic prefix length, and can be indicated by a digital scheme index. For example, in the case of MBMS communication, possible digital schemes could have subcarrier spacings of 15 kHz (corresponding to a 16.7 μs cyclic prefix), 7.5 kHz (corresponding to a 33 μs cyclic prefix), and 1.25 kHz (corresponding to a 200 μs cyclic prefix). A carrier can be associated with one or more digital schemes. For example, a carrier can be a dedicated carrier associated with a single digital scheme or a hybrid carrier that can include subframes or communications of two or more different digital schemes. Subframes or communications of two or more different digital schemes, as well as subframes for broadcast / multicast communication and subframes for unicast communication, can be time-division multiplexed on the carrier by the transmitting device.

[0048] However, for a UE that will process carriers, different digital schemes can be associated with different requirements. For example, assuming a 20MHz carrier bandwidth, a 15kHz digital scheme might require 2048 points of DFT, a 7.5kHz digital scheme might require 4096 points of DFT, and a 1.25kHz digital scheme might require 24576 points of DFT. Therefore, due to baseband processing limitations, a UE using carrier aggregation can support different maximum bandwidths for one digital scheme compared to another. For example, when using MBMS carriers with smaller digital schemes (e.g., 7.5kHz, 1.25kHz, etc.), the UE may not be able to operate the maximum number of supported component carriers concurrently.

[0049] Furthermore, in some cases, the UE can receive a receive-only mode MBMS carrier from a first base station (e.g., the UE can receive a carrier for MBMS communication on it without authentication and / or uplink transmission) and can receive unicast communication from a second base station. In this case, considering the receive-only mode MBMS carrier, the UE may need to signal capability or configuration information so that the second base station can configure communication with the UE within the limits of the UE's capabilities. This can be useful for receive-only mode MBMS carriers associated with digital schemes that impose a high processing burden on the UE.

[0050] Some of the techniques and apparatus described herein provide signaling regarding UE capabilities for multiple different combinations of carrier digital schemes. For example, the UE can signal the set of combinations of carrier digital schemes that the UE can use. As another example, the UE can signal the total bandwidth capability for a first digital scheme and can determine the bandwidth capability for other digital schemes based at least in part on a scaling factor. Furthermore, some of the techniques and apparatus described herein can provide signaling of such capabilities to a base station associated with unicast communication with the UE, allowing the base station to configure communication with the UE to meet limitations or the UE's maximum bandwidth requirements. Therefore, the UE's performance with respect to carriers of different digital schemes (e.g., MBMS carriers) is improved, and the efficiency of bandwidth allocation is increased. This also improves network operation involving communication with the UE.

[0051] Figure 3 This is a diagram illustrating example 300 of carrier capability signaling for a multi-carrier digital scheme according to various aspects of this disclosure. (As shown in...) Figure 3 As shown by reference numeral 310 in the accompanying drawings, UE 120 can be associated with carriers having subcarrier spacings of 15 kHz, 7.5 kHz, and 1.25 kHz. For example, UE 120 is capable of communicating using carriers with subcarrier spacings of 15 kHz, 7.5 kHz, and 1.25 kHz. In such a case, UE 120 can use different amounts of resources (e.g., baseband resources, etc.) for communication with respect to different digital schemes. Therefore, UE 120 can transmit information identifying its capabilities with respect to different digital schemes, as described in more detail below. In some aspects, one or more digital schemes can be associated with an MBMS carrier.

[0052] As shown by reference numeral 320 in the accompanying drawings, UE 120 can determine the maximum bandwidth capability for one of the digital schemes associated with UE 120. Here, although UE 120 determines the maximum bandwidth capability for a 15kHz digital scheme, UE 120 can determine the maximum bandwidth capability for any digital scheme associated with UE 120. The maximum bandwidth capability can be based at least in part on the baseband processing configuration of UE 120, the radio frequency (RF) throughput capability of UE 120, and / or other factors. Here, the maximum bandwidth capability is 100MHz at 15kHz (not shown in conjunction with reference numeral 320).

[0053] As shown by reference numeral 330 in the attached figure, UE 120 can determine the capability to combine carriers for different digital schemes. For example, UE 120 can determine the capability for multiple different combinations of carriers for 15kHz, 7.5kHz, and 1.25kHz digital schemes. In some aspects, UE 120 can determine the set of combinations at least in part based on the worst-case digital scheme for each carrier. For example, suppose UE 120 supports 3-carrier carrier aggregation (CA) for a specific configuration of UE 120. In such a case, UE 120 can determine the maximum number of carriers that can be supported for each digital scheme (e.g., 15kHz, 7.5kHz, and 1.25kHz) and can provide information identifying the maximum number of carriers.

[0054] In some aspects, UE 120 may determine the maximum number of carriers in which UE 120 can support MBMS. For example, UE 120 may determine the maximum number of MBMS carriers for a frequency band combination associated with UE 120 based at least in part on the bandwidth of the frequency band combination, the digital scheme of the MBMS carriers, and / or the baseband capability of UE 120. In some aspects, UE 120 may determine and / or provide for each frequency band combination the maximum number of component carriers in which UE 120 can support MBMS. Alternatively or additionally, UE 120 may determine and / or provide for each frequency band combination information identifying a corresponding set of combinations of a first number of carriers for a first digital scheme and a second number of carriers for a second digital scheme.

[0055] In some respects, UE 120 may determine its capability or maximum number of carriers based at least in part on the default bandwidth used for component carriers. For example, UE 120 may use a bandwidth of 20 MHz or different values ​​as an assumption to determine and / or provide information identifying the capability. In such cases, if the component carriers are associated with different bandwidths, UE 120 may appropriately scale the determined capability. For example, if UE 120 provides information identifying the capability to support a single MBMS carrier at 20 MHz, UE 120 may also support two MBMS carriers, both at 10 MHz.

[0056] In some aspects, UE 120 can determine a scaling factor for the maximum bandwidth capability. For a given maximum bandwidth capability, the scaling factor can identify the relationship between the number of carriers associated with a first digital scheme and the number of carriers associated with a second digital scheme. For example, suppose UE 120 can use 10 carriers for a specific maximum bandwidth at a 15kHz digital scheme and 1 carrier for the same maximum bandwidth at a 1.25kHz digital scheme. In this case, the scaling factor between the 15kHz and 1.25kHz digital schemes could be 10 (e.g., 10 / 1).

[0057] In some aspects, UE 120 may determine multiple different scaling factors. For example, UE 120 may determine the maximum bandwidth capability for a carrier digital scheme (e.g., a non-MBMS carrier digital scheme) and may determine scaling factors for other carriers or digital schemes associated with UE 120. Alternatively, scaling factors for other carriers or digital schemes may be defined in the specifications associated with UE 120.

[0058] In some respects, UE 120 can determine the ability to identify its maximum bandwidth capability and one or more scaling factors associated with UE 120, referred to herein as explicit baseband capability. As an example, suppose UE 120 is associated with carrier digital schemes of 15 kHz, 7.5 kHz, and 1.25 kHz. In this case, UE 120 can determine explicit baseband capability in the following form:

[0059] T>n(15kHz)+An(7.5kHz)+Bn(1.25kHz)

[0060] In this equation, T is the maximum bandwidth capability (in MHz, number of physical resource blocks, or different units), n (15kHz) is the bandwidth or number of carriers for the 15kHz digital scheme, n (7.5kHz) is the bandwidth or number of carriers for the 7.5kHz digital scheme, n (1.25kHz) is the bandwidth or number of carriers for the 1.25kHz digital scheme, A is the scaling factor for the 7.5kHz digital scheme, and B is the scaling factor for the 1.25kHz digital scheme. In some aspects, UE 120 may determine multiple different explicit baseband capabilities, such as the explicit baseband capability for each frequency band combination associated with UE 120. In some aspects, UE 120 may determine T according to the number of component carriers. For example, the number of component carriers may be at least partially based on bandwidth assumptions about the bandwidth of the components (e.g., 20MHz, 10MHz, etc.). In this way, UE 120 may determine information identifying the maximum bandwidth capability using the scaling factor for each digital scheme associated with UE 120.

[0061] In some aspects, UE 120 can determine the maximum bandwidth capability such that it applies only to cells including Multicast-Broadcast Single-Frequency Networks (MBSFNs) using MBMS digital schemes (e.g., 7.5 kHz, 1.25 kHz, etc.). In this way, UE 120 can effectively underestimate its actual maximum bandwidth capability, saving resources that would otherwise be used for communications with the actual maximum bandwidth. Similarly, UE 120 can determine the maximum bandwidth capability, at least in part, based on carriers in which UE 120 is associated with active MBSFN reception. For example, UE 120 can be configured with carriers or cells that are associated with a 15 kHz digital scheme by default and can include subframes with a 1.25 kHz digital scheme. In such a case, unless a subframe with a 1.25 kHz digital scheme is received on the carrier or cell, UE 120 can assume that the carrier or cell is associated with the 15 kHz digital scheme.

[0062] In some aspects, capability can be based at least in part on the number of antennas supported in each frequency band. For example, if a frequency band supports four antennas, UE 120 may need to perform a greater number of Fast Fourier Transforms (FFTs) compared to a frequency band that only supports two antennas. In some aspects, UE 120 can determine capability based at least in part on the following equation:

[0063]

[0064] Where T can be the maximum bandwidth capability across the antenna set, and C is the total number of aggregated carriers. For each aggregated carrier c, Rc This could be the number of receiving antennas in the corresponding frequency band, and B c This could be the bandwidth of the corresponding carrier (e.g., in MHz, resource blocks, or, for the case where T refers to the number of CCs, B...). c =1). If the corresponding carrier has a "worst-case digital scheme" of X kHz, then Otherwise, it is 0.

[0065] In some respects, UE 120 may determine its capability based at least in part on assumptions about the number of antennas. For example, UE 120 may determine its capability based at least in part on assumptions about two receive antennas used for MBSFN subframes. In such a case, UE 120 may determine its capability based at least in part on the following equation, where the value indicating the number of antennas is removed for MBMS digital schemes of 7.5 kHz and 1.25 kHz:

[0066]

[0067] As shown by reference numeral 340, UE 120 can transmit capability identification information. This capability identification information is shown by reference numeral 350. As illustrated, the capability identification information may identify the maximum bandwidth (e.g., 100MHz at a 15kHz digital scheme). Further, the capability identification information may identify a scaling factor (e.g., 2) associated with a 7.5kHz digital scheme and a scaling factor (e.g., 10) associated with a 1.25kHz digital scheme. In some aspects, the capability identification information may identify the maximum bandwidth used for multiple different frequency bands. Additionally or alternatively, the capability identification information may identify a combination set of first carrier numbers for a first digital scheme and second carrier numbers for a second digital scheme that can be concurrently supported by the UE.

[0068] In some respects, UE 120 may determine and / or transmit information identifying a time window and / or one or more subframes associated with capabilities. For example, UE 120 may provide information identifying the maximum bandwidth capability in a particular subframe L based at least in part on the following equation:

[0069] T>n15 l +An7.5 l +Bn1.25 l

[0070] In some respects, UE 120 can provide information identifying the maximum bandwidth capability for a time window of length L (or a set of windows of length L1, L2, L3, etc.) based at least in part on the following equation, where n15 l The number of 15kHz component carriers in subframe l:

[0071]

[0072] In this way, UE 120 can consider different processing times for different digital schemes. In some aspects, UE 120 can use multiple different window lengths. In this case, BS 110 can determine the maximum bandwidth capacity for different values ​​of L and can schedule services with UE 120 accordingly.

[0073] As shown by reference numeral 360, BS 110 can determine the configuration for communication with UE 120 based at least in part on information identifying the capabilities of UE 120. For example, BS 110 can determine a combination of component carriers associated with a corresponding digital scheme, not exceeding the baseband capabilities of UE 120. As shown by reference numeral 370, BS 110 can use this configuration to communicate with UE 120. For example, BS 110 can establish a combination of component carriers for UE 120 and can use the combination of component carriers to communicate with UE 120 or schedule services for UE 120. In this way, UE 120 provides information identifying its capabilities with respect to multiple different carrier digital schemes, and BS 110 communicates with UE 120 at least in part based on these capabilities.

[0074] As pointed out above, Figure 3 This is provided as an example. Other examples are possible and may differ from those provided. Figure 3 The example described.

[0075] Figure 4 This is a diagram illustrating example 400 of carrier capability signaling for a multi-carrier digital scheme configured for a receive-only mode of a multimedia multicast broadcast service, according to various aspects of this disclosure.

[0076] As in Figure 4As shown by reference numeral 410 in the accompanying drawing, UE 120 can be configured with MBMS Receive-Only Mode (ROM) service. MBMS ROM service is a service that allows the UE to receive data on an MBMS carrier without authentication to the Public Land Mobile Network (PLMN) associated with the MBMS carrier. For example, suppose UE 120 is associated with a subscription or authentication with respect to a first cellular network. UE 120 can also receive communications from a second cellular network on an MBMS carrier without authentication on the second cellular network. However, the MBMS carrier can utilize the resources of UE 120 (e.g., radio frequency resources, baseband resources, etc.), particularly where the MBMS carrier is associated with a digital scheme with a higher baseband processing burden. For BS 110 associated with the first cellular network, knowing the capabilities of UE 120 with respect to the MBMS carrier may be beneficial, ensuring that BS 110's communications scheduled by BS 110 do not exceed the limitations of UE 120, as described in more detail below.

[0077] As shown by reference numeral 420, UE 120 may send an MBMS interest indication for the configuration of MBMS ROM service. UE 120 may send the MBMS interest indication to BS 110 associated with unicast communication with UE 120. For example, the MBMS interest indication may be associated with information identifying UE 120's capabilities with respect to one or more MBMS carrier digital schemes. The MBMS interest indication may include information identifying the bandwidth and / or carrier digital scheme on which the UE is receiving MBMS ROM service. Alternatively, BS 110 may receive an MBMS interest indication separate from the information identifying UE 120's capabilities. BS 110 may use the capability-identifying information to determine the configuration for communication with UE 120. As shown by reference numeral 430, the MBMS interest indication may include information identifying UE 120's maximum bandwidth capability and one or more scaling factors for different digital schemes used by UE 120.

[0078] In some aspects, UE 120 may provide information identifying its capabilities based at least in part on the separation and reattachment of the network associated with BS 110. For example, UE 120 may initiate MBMS ROM service. UE 120 may determine information identifying its capabilities with respect to one or more MBMS carriers. UE 120 may determine its carrier aggregation capability or category based at least in part on the capability identification information. For example, UE 120 may downgrade its carrier aggregation capability or category so that its capabilities with respect to BS 110 do not exceed the limitations of UE 120. UE 120 may separate and reattach to the network associated with the BS, and may provide information identifying its carrier aggregation capability or category in connection with the reattachment to the network. In some aspects, BS 110 may process the information identifying UE 120's carrier aggregation capability or category as usual.

[0079] In some respects, UE 120 may provide identification capability information based at least in part on Tracking Area Updates (TAI). For example, when initiating or terminating MBMS ROM service, UE 120 may perform or request a TAI update. A network device associated with BS 110 (e.g., a Mobility Management Entity (MME)) may receive the TAI update and may notify BS 110 that UE 120 has initiated MBMS ROM service. In such a case, BS 110 may request identification capability information from UE 120.

[0080] In some aspects, UE 120 may provide capability identification information based at least in part on Radio Resource Control (RRC) messages. For example, there may be an event defined in the RRC configuration associated with the initiation of MBMS ROM service that causes BS 110 to request information identifying UE 120's capabilities. For example, UE 120 may provide BS 110 with an RRC message indicating that MBMS ROM service has commenced, and BS 110 may request capability identification information based at least in part on the RRC message. Alternatively or additionally, the RRC message may include capability identification information.

[0081] As shown by reference numeral 440 in the attached figure, BS 110 can determine the unicast configuration for communication with UE 120. For example, BS 110 can determine the configuration, such as not exceeding the maximum bandwidth capacity of UE 120 and the RF capabilities of UE 120, based at least in part on information identifying the capabilities of UE 120. As shown by reference numeral 450 in the attached figure, BS 110 can use the unicast configuration to communicate with UE 120. For example, BS 110 can schedule services with UE 120 based at least in part on the unicast configuration, such that it does not exceed the capabilities of UE 120.

[0082] In some aspects, BS 110 can determine the digital scheme of the MBMS carrier associated with MBMS ROM service. For example, BS 110 can detect that a UE is associated with MBMS ROM service (e.g., based at least in part on the temporary mobile group identity provided in the MBMS interest indication) and can obtain information identifying the digital scheme of the MBMS carrier (e.g., from a public database that provides such information). In some aspects, identification capability information can identify the digital scheme of the MBMS carrier. In some aspects, BS 110 can determine the digital scheme information used for MBMS ROM service and can share the digital scheme information with other BS 110s and / or UE 120 (e.g., in a public database, at least in part based on requests from other BS 110s and / or UE 120, etc.).

[0083] As pointed out above, Figure 4 This is provided as an example. Other examples are possible and may differ from those provided. Figure 4 The example described.

[0084] Figure 5 This is a diagram illustrating, for example, an example process 500 performed by a UE according to various aspects of this disclosure. Example process 500 is an example in which a UE (e.g., UE 120) performs carrier capability signaling regarding multiple carrier digital schemes.

[0085] like Figure 5 As shown, in some aspects, process 500 may include: determining the capabilities of the UE in relation to its carrier configuration, wherein the carrier configuration relates to carriers of at least two different digital schemes (block 510). For example, the UE may determine (e.g., using controller / processor 280, etc.) its capabilities. This capability may be related to the UE's carrier configuration. The carrier configuration may be related to carriers of at least two digital schemes. For example, at least one of the at least two digital schemes may be associated with an MBMS carrier.

[0086] like Figure 5As shown, in some aspects, process 500 may include: transmitting capability identification information, wherein the capability identification information identifies the bandwidth or number of carriers supported for a carrier of a first digital scheme and one or more scaling values ​​associated with one or more digital schemes other than the first digital scheme (box 520). For example, the UE may transmit (e.g., using controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, etc.) capability identification information. In some aspects, capability identification information may include information identifying the maximum bandwidth capability. Alternatively or additionally, capability identification information may include information identifying the capability for multiple different frequency band combinations. In some aspects, capability identification information identifies the bandwidth or number of carriers supported for a carrier of a first digital scheme and one or more scaling values ​​associated with one or more digital schemes other than the first digital scheme. For example, the first digital scheme and one or more digital schemes other than the first digital scheme may be digital schemes among at least two different digital schemes.

[0090] In some aspects, one or more scaling values, along with bandwidth or carrier quantity, indicate whether the UE concurrently supports a combination of bandwidth or carrier quantity with a first digital scheme and bandwidth or carrier quantity with a second digital scheme from one or more digital schemes. In some aspects, capability identification information identifies the corresponding bandwidth or carrier quantity and scaling values ​​for multiple different frequency band combinations. In some aspects, capability identification information is provided, at least in part, based on radio resource control messages associated with a Multimedia Multicast Broadcast Service (MBMS) Receive-Only Mode (ROM) session.

[0091] In some aspects, the identification capability information identifier is a combination of frequency bands associated with carriers of at least two different digital schemes, wherein the at least two different digital schemes are associated with corresponding scaling values ​​used to determine the bandwidth or number of carriers supported by the UE. In some aspects, the identification capability information identifier represents an underestimated bandwidth or number of carriers compared to the UE's maximum supported bandwidth.

[0092] In some aspects, the carrier is at least partially based on the carrier associated with the UE in the case of active multicast broadcast single-frequency network reception. In some aspects, the capability identification information identifies the reference bandwidth or number of carriers, the scaling value, and the number of supporting antennas for supporting the frequency band set. The scaling value, bandwidth or number of carriers, and number of supporting antennas indicate whether the UE concurrently supports a combination of a first set of bandwidths or carriers belonging to a first frequency band set and associated with a first digital scheme, and a second set of bandwidths or carriers belonging to a second frequency band set associated with a second digital scheme.

[0093] In some aspects, capability is related to the maximum bandwidth of the UE within a subframe. In other aspects, capability is related to the bandwidth of the UE within one or more time windows.

[0094] In some aspects, the UE may initiate a Multimedia Multicast Service (MBMS) Receive-Only Mode (ROM) session, wherein information identifying capabilities is based at least on the MBMS ROM session.

[0096] Figure 6 This is a diagram illustrating, for example, an example process 600 performed by a BS according to various aspects of this disclosure. Example process 600 is an example in which the BS (e.g., BS 110) performs carrier capability signaling regarding multiple carrier digital schemes.

[0097] like Figure 6 As shown, in some aspects, process 600 may include: receiving information identifying the capabilities of a user equipment (UE) in relation to a carrier configuration of the UE, wherein the carrier configuration relates to carriers of at least two different digital schemes, wherein the capability identification information identifies the bandwidth or number of carriers supported for a first digital scheme and one or more scaling values ​​associated with one or more digital schemes other than the first digital scheme (box 610). For example, the BS may receive (e.g., using antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, etc.) the information identifying the capabilities of the UE. The capability identification information may relate to the carrier configuration of the UE. The carrier configuration of the UE may relate to carriers of at least two different digital schemes. For example, at least one of the at least two different digital schemes may be associated with an MBMS carrier. In some aspects, the capability identification information identifies the bandwidth or number of carriers supported for a first digital scheme and one or more scaling values ​​associated with one or more digital schemes other than the first digital scheme. For example, the first digital scheme and one or more digital schemes other than the first digital scheme may be digital schemes among at least two different digital schemes.

[0098] like Figure 6 As shown, in some aspects, process 600 may include determining a configuration for communication with the UE, at least in part based on identification capability information (block 620). For example, the base station may determine (e.g., using controller / processor 240, etc.) a configuration for communication with the UE. This configuration may be at least in part based on identification capability information. For example, the configuration may be determined such that the base station does not exceed the UE's baseband limits.
