Field of the Disclosure

[0003] In general, aspects of the present disclosure relate to wireless communication, and techniques and apparatus for indicating user equipment (UE) capabilities for layer 1 signal to interference plus noise ratio (L1 - SINR) measurements. Background Art

[0004] Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasting. A typical wireless communication system may employ multiple access technologies capable of supporting 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 / Advanced LTE is an enhanced set of mobile standards for the Universal Mobile Telecommunications System (UMTS) released by the 3rd Generation Partnership Project (3GPP).

[0005] A wireless network may include multiple base stations (BSs) capable of supporting communication for multiple user equipments (UEs). The UEs may communicate with the BSs via a downlink and an uplink. The downlink (or forward link) refers to the communication link from the BS to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the BS. As will be described in more detail herein, the BS may be referred to as a Node B, gNB, access point (AP), radio head, transmission reception point (TRP), New Radio (NR) BS, 5G Node B, etc.

[0006] The above multi-access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipments to communicate at the urban, national, regional, and even global levels. NR, which may also be referred to as 5G, is an enhanced set of the LTE mobile standard released by 3GPP. NR is designed to better support mobile broadband Internet access by: improving spectral efficiency, reducing costs, improving services, leveraging new spectrums, and better integrating with other open standards that use cyclic prefix (CP)-orthogonal frequency division multiplexing (CP-OFDM) on the downlink (DL) and CP-OFDM and / or SC-FDM (e.g., also referred to as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink (UL), as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR, and other wireless access technologies, as well as the telecommunication standards that employ these technologies, remain useful.

[0038] Aspects of the present disclosure are described more fully hereinafter with reference to the accompanying drawings. However, the present disclosure may be embodied in different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. On the contrary, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art. Those skilled in the art will recognize, in light of the teachings herein, that the scope of the present disclosure is intended to cover any aspect of the present disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the present disclosure. For example, an apparatus or a practice method may be implemented with any number of the aspects set forth herein. Additionally, the scope of the present disclosure is intended to cover such apparatus and methods practiced using other structures, functions, or combinations of structures and functions in addition to or different from the aspects of the present disclosure set forth herein. It should be understood that any aspect of the present disclosure disclosed herein may be embodied by one or more elements of a claim.

[0039] Several aspects of a telecommunications system will now be presented with reference to various apparatuses and techniques. These apparatuses and techniques will be described in detail hereinafter and will be illustrated in the drawings by various boxes, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented in hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

[0040] It should be noted that although terms generally associated with 5G or NR radio access technology (RAT) may be used herein to describe aspects, aspects of the present disclosure may be applied to other RATs such as 3G RAT, 4G RAT, and / or post-5G RAT (e.g., 6G).

[0041] Figure 1 is a schematic diagram showing an example of a wireless network 100 in accordance with various aspects of the present disclosure. The wireless network 100 may be or may include elements of a 5G (NR) network, an LTE network, etc. The wireless network 100 may include a plurality of base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d) and other network entities. A base station (BS) is an entity that communicates with a user equipment (UE) and may also be referred to as an NR BS, a Node B, a gNB, a 5G Node B (NB), an access point, a transmit receive point (TRP), etc. Each BS may provide communication coverage for a particular geographic area. In 3GPP, depending on the context in which the term is used, the term "cell" may refer to the coverage area of a BS and / or the BS subsystem serving that coverage area.

[0042] The BS can provide communication coverage for macro cells, pico cells, femto cells, and / or another type of cell. A macro cell can cover a relatively large geographical area (e.g., with a radius of several kilometers) and can allow unrestricted access by UEs with service subscriptions. A pico cell can cover a relatively small geographical area and can allow unrestricted access by UEs with service subscriptions. A femto cell can cover a relatively small geographical area (e.g., a home) and can allow restricted access by UEs associated with the femto cell (e.g., UEs in a Closed Subscriber Group (CSG)). The BS for a macro cell can be referred to as a macro BS. The BS for a pico cell can be referred to as a pico BS. The BS for a femto cell can be referred to as a femto BS or a home BS. In Figure 1 the example shown in, 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. The 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" can be used interchangeably herein.

[0043] In some aspects, a cell may not necessarily be stationary, and the geographical area of the cell can move according to the position of the mobile BS. In some aspects, the BSs can be interconnected with each other and / or interconnected to one or more other BSs or network nodes (not shown) in the wireless network 100 through various types of backhaul interfaces such as direct physical connections, virtual networks, and / or using any applicable transport network, etc.

[0044] The wireless network 100 can also include relay stations. A relay station is an entity that receives the transmission of data from an upstream station (e.g., a BS or a UE) and sends the transmission of data to a downstream station (e.g., a UE or a BS). A relay station can also be a UE that can relay transmissions for other UEs. In Figure 1 the example shown in, relay BS 110d can communicate with macro BS 110a and UE 120d to facilitate communication between BS 110a and UE 120d. The relay BS can also be referred to as a relay station, a relay base station, a repeater, etc.

[0045] The wireless network 100 can be a heterogeneous network including different types of BSs (e.g., macro BS, pico BS, femto BS, relay BS, etc.). These different types of BSs can have different transmission power levels, different coverage areas, and different impacts on interference in the wireless network 100. For example, a macro BS can have a high transmission power level (e.g., 5 to 40 watts), while pico BSs, femto BSs, and relay BSs can have lower transmission power levels (e.g., 0.1 to 2 watts).

[0046] The network controller 130 can be coupled to a set of BSs and provide coordination and control for these BSs. The network controller 130 can communicate with the BSs via a backhaul. The BSs can also communicate with each other directly or indirectly via a wireless or wired backhaul.

[0047] UEs 120 (e.g., 120a, 120b, 120c) can be distributed throughout the wireless network 100, and each UE can be stationary or mobile. UEs can also be referred to as access terminals, terminals, mobile stations, user devices, stations, etc. A UE can be a cellular phone (e.g., a smart phone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet computer, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device or equipment, a biosensor / device, a wearable device (smart watch, smart clothing, smart glasses, smart wristband, smart jewelry (e.g., smart ring, smart bracelet)), an entertainment device (e.g., a music or video device, or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing device, a global positioning system device, or any other suitable device configured to communicate via a wireless or wired medium.

[0048] Some UEs may be considered as 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 may communicate with a base station, another device (e.g., a remote device), or some other entity. A wireless node may provide, for example, a connection to or from a network (e.g., a wide area network such as the Internet or a cellular network) via a wired or wireless communication link. Some UEs may be considered as Internet of Things (IoT) devices, and / or may be implemented as NarrowBand IoT (NB-IoT) devices. Some UEs may be considered as Customer Premises Equipment (CPE). UE 120 may be included inside a housing that houses components of UE 120, such as a processor component, a memory component, etc. In some aspects, the processor component and the memory component may be coupled together. For example, the processor component (e.g., one or more processors) and the memory component (e.g., a memory) may be operatively coupled, communicatively coupled, electronically coupled, electrically coupled, etc.

[0049] In general, any number of wireless networks may be deployed in a given geographical area. Each wireless network may support a specific RAT and may operate on one or more frequencies. The RAT may also be referred to as a radio technology, an air interface, etc. The frequency may also be referred to as a carrier, a frequency channel, etc. Each frequency may support a single RAT in a given geographical area to avoid interference between wireless networks of different RATs. In some cases, an NR or 5G RAT network may be deployed.

[0050] In some aspects, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using the base station 110 as a medium to communicate with each other). For example, UE120 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) protocol, vehicle-to-infrastructure (V2I) protocol, etc.), a mesh network, etc. In such cases, UE120 may perform scheduling operations, resource selection operations, and / or other operations performed by the base station 110 described elsewhere herein.

[0051] Devices of the wireless network 100 may communicate using the electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc. based on frequency or wavelength. For example, devices of the wireless network 100 may communicate using an operating band having a first frequency range (FR1) that may span from 410 MHz to 7.125 GHz, and / or may communicate using an operating band having a second frequency range (FR2) that spans from 24.25 GHz to 52.6 GHz. The frequencies between FR1 and FR2 are sometimes referred to as mid-band frequencies. Although a portion of FR1 is greater than 6 GHz, FR1 is generally referred to as the "sub-6 GHz" band. Similarly, FR2 is generally referred to as the "millimeter wave" band, although it is different from the extremely high frequency (EHF) band (30 GHz - 300 GHz) defined by the International Telecommunication Union (ITU) as the "millimeter wave" band. Thus, unless otherwise explicitly stated, it should be understood that the term "sub-6 GHz", etc., if used herein, may broadly represent frequencies less than 6 GHz, frequencies within FR1, and / or mid-band frequencies (e.g., greater than 7.125 GHz). Similarly, unless otherwise explicitly stated, it should be understood that the term "millimeter wave", etc., if used herein, may broadly represent frequencies within the EHF band, frequencies within FR2, and / or mid-band frequencies (e.g., less than 24.25 GHz). Frequencies included in FR1 and FR2 that may be modified are contemplated, and the techniques described herein apply to those modified frequency ranges.

[0052] As noted above, Figure 1 is provided as an example. Other examples may be different from those Figure 1 described.

[0053] Figure 2 is a schematic diagram of an example 200 of a base station 110 communicating with a UE 120 in a wireless network in accordance with aspects of the present disclosure. The base station 110 may be equipped with T antennas 234a through 234t, and the UE 120 may be equipped with R antennas 252a through 252r, where, generally speaking, T ≥ 1 and R ≥ 1.

[0054] At base station 110, transmit processor 220 may receive data for one or more UEs from data source 212, select one or more modulation and coding schemes (MCSs) for each UE at least in part based on channel quality indicators (CQIs) received from the UEs, process (e.g., encode and modulate) the data for each UE at least in part based on the selected MCS(s) for the UE, and provide data symbols for all UEs. Transmit processor 220 may also process system information (e.g., for semi-static resource partitioning information (SRPI), etc.) and control information (e.g., CQI requests, grants, upper layer signaling, etc.) and provide overhead symbols and control symbols. Transmit processor 220 may also generate reference symbols for reference signals (e.g., cell-specific reference signal (CRS), demodulation reference signal (DMRS), etc.) and synchronization signals (e.g., primary synchronization signal (PSS) and secondary synchronization signal (SSS)). If applicable, transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and / or reference symbols and may provide T output symbol streams to T modulators (MOD) 232a through 232t. Each modulator 232 may process its respective output symbol stream (e.g., for OFDM, etc.) to obtain an output sample stream. Each modulator 232 may further process the output sample stream (e.g., convert to analog, amplify, filter, and up-convert) to obtain a downlink signal. The T downlink signals from modulators 232a through 232t may be transmitted via T antennas 234a through 234t, respectively.

[0055] At the UE 120, antennas 252a through 252r may receive downlink signals from the base station 110 and / or other base stations, and may provide the received signals to demodulators (DEMOD) 254a through 254r, respectively. Each demodulator 254 may condition (e.g., filter, amplify, down-convert, and digitize) the received signal to obtain an input sample. Each demodulator 254 may further process the input sample (e.g., for OFDM, etc.) to obtain a received symbol. The MIMO detector 256 may obtain the received symbols from all R demodulators 254a through 254r, perform MIMO detection on the received symbols (if applicable), and provide the detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide the decoded data for the UE 120 to the data sink 260, and provide the decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP), a received signal strength indicator (RSSI), a reference signal received quality (RSRQ), a channel quality indicator (CQI), etc. In some aspects, one or more components of the UE 120 may be included in a housing 284.

[0056] The network controller 130 may include a communication unit 294, a controller / processor 290, and a memory 292. The network controller 130 may include, for example, one or more devices in a core network. The network controller 130 may communicate with the base station 110 via the communication unit 294.

[0057] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reporting including RSRP, RSSI, RSRQ, CQI, etc.). The transmit processor 264 may also generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded (if applicable) by the TX MIMO processor 266, further processed (e.g., for DFT-s-OFDM, CP-OFDM, etc.) by the modulators 254a through 254r, and sent to the base station 110. In some aspects, the UE 120 includes a transceiver. The transceiver may include any combination of (multiple) antennas 252, modulators and / or demodulators 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and a memory 282 to perform any aspect of the methods described herein.

[0058] At base station 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 receive processor 238 to obtain decoded data and control information transmitted by UE 120. Receive processor 238 can provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Base station 110 can include communication unit 244 and communicate with network controller 130 via communication unit 244. Base station 110 can include scheduler 246 to schedule UE 120 for downlink and / or uplink communication. In some aspects, base station 110 includes a transceiver. The transceiver can include any combination of (a plurality of) antennas 234, modulator and / or demodulator 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver can be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein.

[0059] As described in more detail elsewhere herein, controller / processor 240 of base station 110, controller / processor 280 of UE 120, and / or any other components in FIG. 2 can perform one or more techniques associated with indicating the ability of UE 120 for layer 1 signal-to-interference-plus-noise ratio (L1-SINR) measurement. For example, controller / processor 240 of base station 110, controller / processor 280 of UE 120, and / or any other components in FIG. 2 can execute or direct, for example, Figure 4 process 400, Figure 5 process 500, and / or the operations of other processes described herein. Memories 242 and 282 can store data and program codes for base station 110 and UE 120, respectively. In some aspects, memory 242 and / or memory 282 can include a non-transitory computer-readable medium storing one or more instructions for wireless communication. For example, one or more instructions, when executed by one or more processors of base station 110 and / or UE 120 (e.g., directly, or after compilation, conversion, interpretation, etc.), can cause one or more processors, UE 120, and / or base station 110 to execute or direct, for example, Figure 4 process 400, Figure 5 process 500, and / or the operations of other processes described herein. In some aspects, executing the instructions includes running the instructions, converting the instructions, compiling the instructions, interpreting the instructions, etc.

[0060] In some aspects, the UE 120 may include: a unit for sending information indicating the L1 - SINR measurement capability of the UE 120 to the base station 110, where the information indicating the L1 - SINR measurement capability includes one or more individual configurations for one or more resources carrying reference signals; a unit for receiving, at least in part based on the L1 - SINR measurement capability, reference signals carried on one or more resources from the base station 110, etc. In some aspects, such units may include: one or more components of the UE 120 described in conjunction with Figure 2 such as the controller / processor 280, transmit processor 264, TX MIMO processor 266, MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, etc.

[0061] In some aspects, the base station 110 may include: a unit for receiving information indicating the L1 - SINR measurement capability of the UE 120 from the UE 120, where the information indicating the L1 - SINR measurement capability includes one or more individual configurations for one or more resources carrying reference signals; a unit for sending, at least in part based on the L1 - SINR measurement capability, reference signals carried on one or more resources to the UE 120, etc. In some aspects, such units may include: one or more components of the base station 110 described in conjunction with Figure 2 such as antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, antenna 234, etc.

[0062] As noted above, Figure 2 is provided as an example. Other examples may be different from the example described with respect to Figure 2 the example described.

[0063] In a wireless network (such as, an NR network, etc.), a UE can obtain one or more layer 1 (L1) measurements based on reference signals sent by one or more base stations, and the UE can send a report including the (multiple) L1 measurements to the base station so that the base station can control transmission parameters (such as, transmission power, beamforming configuration, etc.). For example, in some cases, the L1 measurement can include a reference signal received power (RSRP) measurement, and the UE can obtain the RSRP measurement by measuring the power of the reference signal received from any nearby transmitter, regardless of whether the measured power includes a signal (e.g., from the serving base station) or interference (e.g., from a neighboring base station). Accordingly, in NR, L1-SINR measurements have been added as values that can be reported in a measurement report (such as, a channel state information (CSI) report). For example, to obtain an L1-SINR measurement, the UE can measure the signal separately from the interference. Generally speaking, the L1-SINR measurement is captured in a time duration shorter than other L1 measurements (such as, the L1-RSRP measurement), whereby the L1-SINR measurement can be useful when capturing an instantaneous SINR measurement, an unfiltered measurement, a measurement where the time is not long enough for the interfering base station to cycle through many downlink beams, a measurement where the interference term is not averaged over many transmit beams and / or receive beams, etc.

[0064] However, there are a variety of different techniques that can be used to send reference signals that enable the UE to obtain L1-SINR measurements. For example, the reference signal can be sent using a channel measurement resource (CMR) without dedicated interference measurement resources (IMR), using a CMR with dedicated IMR (e.g., zero-power IMR (ZP IMR) and / or CSI IMR), using a CMR with dedicated non-zero-power IMR (NZP IMR), using a CMR with dedicated ZP IMR and dedicated NZP IMR, etc. In addition, in some cases, the CMR can be configured as a synchronization signal block (SSB) or a channel state information reference signal (CSI-RS), and the IMR (e.g., dedicated ZP IMR or dedicated NZP IMR) can be configured as an SSB or a CSI-RS. Accordingly, the UE may not generally support all possible L1-SINR measurement techniques, and in some cases, the UE may only support traditional L1 measurement techniques (e.g., may only support L1-RSRP measurements and lack support for any L1-SINR measurement techniques). In this regard, without knowing the specific L1-SINR measurement techniques supported by the UE (if any), including the supported configurations for the CMR and / or IMR, the base station may not be able to correctly configure the reference signal to be sent to the UE.

[0065] Some aspects described herein relate to techniques and apparatus for indicating to a base station UE capabilities for L1-SINR measurements. For example, in some aspects, a UE may send information indicating the UE's L1-SINR measurement capabilities to a base station, which may enable the base station to configure one or more resources for transmitting reference signals at least in part based on the UE's L1-SINR measurement capabilities. In this way, the base station may transmit a reference signal on one or more resources at least in part based on the L1-SINR measurement capabilities, and the UE may receive the reference signal on one or more resources at least in part based on the L1-SINR measurement capabilities, such that the UE may obtain one or more L1 measurements supported by the UE. In this way, when the UE supports one or more L1-SINR measurement techniques, the base station may configure and / or select a reference signal according to the supported L1-SINR measurement technique, which may enable the UE to provide instantaneous SINR measurements, unfiltered measurements, measurements that are not long enough in time for the interfering base station to cycle through many downlink beams, etc. Additionally or alternatively, when the UE does not support any L1-SINR measurement techniques, the base station may configure a reference signal according to traditional L1 measurement techniques supported by the UE to ensure that the UE can still obtain and report information that the base station may use to configure transmission parameters for the UE.

[0066] Figure 3 is a schematic diagram illustrating an example 300 of indicating UE capabilities for L1-SINR measurements in accordance with various aspects of the present disclosure. As Figure 3 shown, example 300 includes a UE 120 communicating with a base station 110 over a wireless network (e.g., wireless network 100).

[0067] In some aspects, as described herein, a wireless network may support various resource configurations to enable L1-SINR measurements. For example, in some aspects, the resource configuration may include: a first configuration in which reference signals (e.g., synchronization signal blocks (SSBs) and / or CSI-RSs and other examples) are transmitted using a CMR without dedicated IMR; a second configuration in which reference signals are transmitted using a CMR with dedicated resources (e.g., ZP IMR and / or CSI IMR) in which the base station 110 does not transmit signals; a third configuration in which reference signals are transmitted using a CMR with dedicated NZP IMR; a fourth configuration in which reference signals are transmitted using a CMR with dedicated ZP IMR and / or CSI IMR and dedicated NZP IMR; and so on. Additionally, in each case, the CMR and IMR (e.g., ZP IMR and / or NZP IMR) may include an SSB or CSI-RS (e.g., NZP CSI-RS). Further, in some aspects, the wireless network may support one or more resource configurations to enable legacy L1 measurements (e.g., L1-RSRP measurements).

[0068] As Figure 3 shown in and the attached reference numeral 310, the UE 120 may transmit information indicating the L1-SINR measurement capabilities of the UE 120, and the base station 110 may receive information indicating the L1-SINR measurement capabilities of the UE 120. For example, in some aspects, the information indicating L1-SINR measurement capabilities may jointly indicate whether the UE 120 supports all L1-SINR resource configurations implemented in the wireless network. For example, the L1-SINR measurement capabilities may include values such as "1", "supported", etc. to indicate that the UE 120 supports all L1-SINR resource configurations implemented in the wireless network, or values such as "0", "not supported", etc. to indicate that the UE 120 does not support any L1-SINR resource configurations (e.g., only supports legacy L1 measurements). In this case, when the L1-SINR measurement capabilities indicate that the UE 120 supports all L1-SINR resource configurations implemented in the wireless network, the L1-SINR measurement capabilities may indicate that the UE 120 can obtain L1-SINR measurements regardless of whether the SSB or CSI-RS (e.g., NZP CSI-RS) is configured as the CMR and / or IMR.

[0069] Additionally or alternatively, information indicating the L1-SINR measurement capabilities of UE 120 can separately indicate whether UE 120 supports separate L1-SINR resource configurations implemented in a wireless network. For example, UE 120 can send one or more L1-SINR measurement capabilities to separately indicate whether UE 120 supports L1-SINR measurements on a CMR without a dedicated IMR, on a CMR with a dedicated ZP IMR or CSI IMR, on a CMR with a dedicated NZP IMR, on a CMR with a dedicated ZP IMR and a dedicated NZP IMR, etc. For example, one or more L1-SINR measurement capabilities can each be associated with a set of candidate values such as {'0', '1'}, {'supported', 'not supported'}, etc., and UE 120 can provide a value from the set of values in the candidate set to the base station 110 to separately indicate the L1-SINR measurement capabilities for one or more L1-SINR resource configurations in the L1-SINR resource configuration. For example, in some aspects, the information indicating the L1-SINR measurement capabilities can include a bitmap with one or more entries, each entry corresponding to an L1-SINR resource configuration and having a value to indicate whether UE 120 supports the ability to obtain L1-SINR measurements using the corresponding L1-SINR resource configuration. Additionally or alternatively, for each separate L1-SINR resource configuration, UE 120 can indicate whether UE 120 supports an L1-SINR resource configuration having an SSB or CSI-RS (e.g., NZP CSI-RS) configured as a CMR and / or having an SSB or CSI-RS (e.g., NZP CSI-RS) configured as an IMR. In other words, each L1-SINR resource configuration and the corresponding L1-SINR measurement capabilities can be indicated based on the association between the reference signal for signal measurement and the CMR (e.g., an SSB or CSI-RS used as a CMR) and the resources for interference measurement (e.g., a dedicated CSI IMR, a dedicated NZP IMR, and / or a dedicated or configured IMR and other examples). Accordingly, in this case, there can be up to sixteen (16) total permutations of L1-SINR resource configurations (e.g., four L1-SINR resource configurations associated with four possible combinations, where in each L1-SINR resource configuration, the CMR and IMR can be configured as an SSB and / or CSI-RS).

[0070] Accordingly, in some aspects, the UE 120 may separately indicate support for each individual L1-SINR resource configuration implemented in the wireless network, which may include providing separate indications as to whether the UE 120 supports configuring the CMR as an SSB, configuring the CMR as a CSI-RS, configuring the IMR as an SSB, configuring the IMR as a CSI-RS, etc. according to the L1-SINR resource configuration implemented in the wireless network. For example, in one possible use case, the wireless network may implement five (5) different L1-SINR resource configurations, which may include: a first configuration based on CMR without dedicated IMR, a second configuration based on CSI-RS (where the CSI-RS is a CMR with dedicated ZP IMR), a third configuration based on CSI-RS (where the CSI-RS is a CMR with dedicated NZP IMR), a fourth configuration based on SSB (where the SSB is a CMR with dedicated ZP IMR), and a fifth configuration based on SSB (where the SSB is a CMR with dedicated NZP IMR). In this example, the L1-SINR measurement capabilities sent by the UE 120 may separately indicate whether each of the 5 different L1-SINR resource configurations is supported or not supported.

[0071] As Figure 3 Further shown in and by reference numeral 320 in the figures, the base station 110 may transmit one or more reference signals on one or more resources at least partially based on the L1-SINR measurement capabilities of the UE 120, and the UE 120 may receive the one or more reference signals. For example, in cases where the UE 120 indicates that one or more L1-SINR measurement techniques are supported, the reference signal may be an SSB, a CSI-RS (e.g., NZP CSI-RS), and / or another suitable reference signal transmitted on the CMR, which may include a set of time and frequency resources for measuring the channel. Additionally, in cases where the L1-SINR measurement techniques indicated as supported by the UE 120 include techniques associated with dedicated IMR (e.g., dedicated ZP IMR, CSI IMR, NZP IMR, etc.), the base station 110 may configure the IMR (e.g., as an SSB, CSI-RS, etc.) according to the indicated capabilities. For example, in some aspects, the IMR may generally include a dedicated set of time and frequency resources that are separated from the CMR and are used to enable the UE 120 to separately measure interference from signals transmitted via the CMR. Alternatively, in cases where the UE 120 indicates that the UE 120 lacks support for any L1-SINR measurement techniques, the base station 110 may use a set of time and frequency resources associated with traditional L1 measurements to transmit the reference signals.

[0072] As Figure 3 further shown in and by reference numeral 330 in the figures, UE 120 may obtain one or more L1 measurements based at least in part on one or more reference signals. For example, when at least in part based on UE 120 indicating support for L1-SINR measurements on a CMR without dedicated IMR, and one or more reference signals are transmitted on the CMR without dedicated IMR, UE 120 may measure one or more reference signals transmitted by base station 110 on the CMR, and in this case, there will not be any IMR including separate configurations to enable UE 120 to measure interference. On the contrary, to measure interference, UE 120 may collect signal power associated with SSB, CSI-RS, etc. in one or more time and frequency resources that are external to the set of time and frequency resources scheduled for UE 120 (e.g., outside the CMR, or in other time and frequency resources where UE 120 is not intended to be the target receiver). In this case, the signal power collected in time and frequency resources external to the set of time and frequency resources scheduled for UE 120 may represent interference.

[0073] Additionally or alternatively, when at least in part based on UE 120 indicating support for L1-SINR measurements on a CMR with dedicated IMR, and one or more reference signals are transmitted on the CMR with dedicated IMR (e.g., ZP IMR and / or CSI IMR), UE 120 may measure the (multiple) reference signals transmitted by base station 110 on the CMR in a similar manner as described above. However, in this case, base station 110 may configure separate dedicated ZP IMR and / or CSI IMR, which may include a set of time and frequency resources in which base station 110 will not transmit signals (e.g., base station 110 does not transmit anything, or transmits SSB, CSI-RS, etc. with zero power in the set of time and frequency resources corresponding to the IMR). Accordingly, in this case, any signal power collected or measured by UE 120 in the set of time and frequency resources corresponding to the IMR may be considered interference (e.g., background interference caused by signals transmitted by other nearby base stations).

[0074] Additionally or alternatively, when at least partially based on an indication from UE 120 of support for L1-SINR measurements on a CMR with a dedicated NZP IMR, one or more reference signals are transmitted on the CMR with the dedicated NZP IMR, UE 120 may measure the (multiple) reference signals transmitted by base station 110 on the CMR in a manner similar to that described above. In this case, base station 110 may configure a separate dedicated NZP IMR, which may include a set of time and frequency resources in which only base station 110 transmits the (multiple) reference signals. Accordingly, in this case, signal measurements may be obtained from the (multiple) reference signals transmitted on the NZP IMR, and this signal measurement may be subtracted from the signal power measured on the CMR, such that the difference between the signal power measured on the NZP IMR and the signal power measured on the CMR may be considered interference.

[0075] Additionally or alternatively, when at least partially based on an indication from UE 120 of support for L1-SINR measurements on a CMR with a dedicated ZP or CSI IMR and a dedicated NZP IMR, one or more reference signals are transmitted on the CMR with the dedicated ZP or CSI IMR and the dedicated NZP IMR, the reference signals may be transmitted and measured using the above dedicated ZP or CSI IMR techniques, the above dedicated NZP IMR techniques, and / or a combination thereof. Further, in cases where UE 120 supports more than one L1-SINR measurement technique, base station 110 may select one or more of the supported L1-SINR measurement techniques that provide the best performance, reliability, etc.

[0076] Additionally or alternatively, when at least partially based on an indication from UE 120 of a lack of support for L1-SINR measurements, one or more reference signals are transmitted on traditional reference signal resources, the (multiple) reference signals may be transmitted and measured using traditional techniques (e.g., L1-RSRP measurement techniques).

[0077] As Figure 3As further shown in the middle and the attached reference numeral 340, the UE 120 may send a report (e.g., a report associated with a periodic, aperiodic, or semi-persistent reporting configuration), and the base station 110 may receive the report, which includes one or more L1 measurements obtained at least in part based on the reference signal(s) sent by the base station 110. For example, in a case where the UE 120 indicates support for L1-SINR measurements, the one or more L1 measurements provided in the report may include one or more L1-SINR measurements obtained using one or more of the above techniques. Additionally or alternatively, the one or more L1 measurements provided in the report may include one or more conventional L1 measurements, such as L1-RSRP measurements (e.g., when the UE 120 lacks support for L1-SINR measurements, as additional L1 measurements in addition to L1-SINR measurements, etc.). Accordingly, in this way, the base station 110 may configure subsequent communication parameters (e.g., transmission power, beamforming configuration, etc.) for the UE 120 at least in part based on the one or more L1 measurements.

[0078] As pointed out above, Figure 3 is provided as an example. Other examples may be different from the example regarding Figure 3 described.

[0079] Figure 4 is a schematic diagram showing an example process 400 performed by a UE, for example, according to various aspects of the present disclosure. The example process 400 is an example in which a UE (e.g., UE 120, etc.) performs operations associated with indicating the UE's ability for L1-SINR measurements.

[0080] As Figure 4 shown, in some aspects, the process 400 may include: sending information indicating the UE's L1-SINR measurement ability to the base station, where the information indicating the L1-SINR measurement ability includes one or more individual configurations for one or more resources carrying reference signals (block 410). For example, as described above, the UE may (e.g., using Figure 2 the controller / processor 280, the transmitting processor 264, the TX MIMO processor 266, the MOD 254, the antenna 252 shown in Figure 6 the transmitting component 604 shown in

[0081] As Figure 4As further shown, in some aspects, process 400 may include: receiving a reference signal carried on one or more resources from a base station based at least in part on L1 - SINR measurement capabilities (block 420). For example, as described above, the UE may, based at least in part on L1 - SINR measurement capabilities, (e.g., using Figure 2 antenna 252, DEMOD 254, MIMO detector 256, receive processor 258, controller / processor 280, and / or memory 282 shown in Figure 6 receive component 606 shown in

[0082] to receive a reference signal carried on one or more resources from a base station.

[0083] In a first aspect, one or more separate configurations include a configuration in which one or more resources for carrying the reference signal include a CMR without a dedicated IMR.

[0084] In a second aspect, separately or in combination with the first aspect, one or more separate configurations include a configuration in which one or more resources for carrying the reference signal include a CMR with a dedicated IMR in which the base station does not transmit a signal.

[0085] In a third aspect, separately or in combination with one or more of the first and second aspects, one or more separate configurations include a configuration in which one or more resources for carrying the reference signal include a CMR with a dedicated NZP IMR.

[0086] In a fourth aspect, separately or in combination with one or more of the first to third aspects, one or more separate configurations include a configuration in which one or more resources for carrying the reference signal include a CMR with a dedicated IMR and a dedicated NZP IMR.

[0087] In a fifth aspect, separately or in combination with one or more of the first to fourth aspects, each of one or more separate configurations includes a CMR, and information indicating L1 - SINR measurement capabilities also indicates whether the UE supports configuring the CMR as an SSB, CSI - RS, or a combination thereof.

[0088] In a sixth aspect, separately or in combination with one or more of the first to fifth aspects, at least one of one or more separate configurations includes an IMR, and information indicating L1 - SINR measurement capabilities also indicates whether the UE supports configuring the IMR as an SSB, CSI - RS, or a combination thereof.

[0089] In a seventh aspect, alone or in combination with one or more of the first through sixth aspects, process 400 includes: obtaining an L1 - SINR measurement based at least in part on a reference signal and sending a report including the L1 - SINR measurement to a base station.

[0090] Although Figure 4 example blocks of process 400 are shown, in some aspects, process 400 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks compared to the blocks shown in Figure 4 . Additionally or alternatively, two or more of the blocks of process 400 may be executed in parallel.

[0091] Figure 5 is a schematic diagram showing an example process 500, performed, for example, by a base station, according to various aspects of the present disclosure. Example process 500 is an example where a base station (e.g., base station 110, etc.) performs operations associated with an indicated UE capability for L1 - SINR measurement.

[0092] As Figure 5 shown, in some aspects, process 500 may include: receiving, from a UE, information indicating the UE's L1 - SINR measurement capability, where the information indicating the L1 - SINR measurement capability includes one or more individual configurations for one or more resources carrying a reference signal (block 510). For example, as described above, a base station may (e.g., using the antenna 234, DEMOD 232, MIMO detector 236, receive processor 238, and / or controller / processor 240 shown in Figure 2 , the receive component 704 shown in Figure 7 ) receive, from the UE, information indicating the UE's L1 - SINR measurement capability. In some aspects, the information indicating the L1 - SINR measurement capability includes one or more individual configurations for one or more resources carrying a reference signal.

[0093] As Figure 5 further shown, in some aspects, process 500 may include: sending, to the UE, a reference signal carried on one or more resources based at least in part on the L1 - SINR measurement capability (block 520). For example, as described above, a base station may, based at least in part on the L1 - SINR measurement capability, (e.g., using the controller / processor 240, transmit processor 220, TX MIMO processor 230, MOD 232, and / or antenna 234 shown in Figure 2 , the transmit component 708 shown in Figure 7 ) send, to the UE, a reference signal carried on one or more resources.

[0094] Procedure 500 may include additional aspects, such as any single aspect or any combination of aspects of any single aspect or one or more other procedures described below and / or elsewhere herein.

[0095] In a first aspect, one or more separate configurations include a configuration in which one or more resources for carrying reference signals include a CMR without dedicated IMR.

[0096] In a second aspect, separately or in combination with the first aspect, one or more separate configurations include a configuration in which one or more resources for carrying reference signals include a CMR with dedicated IMR, in which the base station does not transmit signals.

[0097] In a third aspect, separately or in combination with one or more of the first and second aspects, one or more separate configurations include a configuration in which one or more resources for carrying reference signals include a CMR with dedicated NZP IMR.

[0098] In a fourth aspect, separately or in combination with one or more of the first to third aspects, one or more separate configurations include a configuration in which one or more resources for carrying reference signals include a CMR with dedicated IMR and dedicated NZP IMR.

[0099] In a fifth aspect, separately or in combination with one or more of the first to fourth aspects, each of one or more separate configurations includes a CMR, and information indicating L1-SINR measurement capabilities also indicates whether the UE supports configuring the CMR as an SSB, CSI-RS, or a combination thereof.

[0100] In a sixth aspect, separately or in combination with one or more of the first to fifth aspects, at least one of one or more separate configurations includes an IMR, and information indicating L1-SINR measurement capabilities also indicates whether the UE supports configuring the IMR as an SSB, CSI-RS, or a combination thereof.

[0101] In a seventh aspect, separately or in combination with one or more of the first to sixth aspects, procedure 500 includes: receiving a report from the UE, the report including an L1-SINR measurement obtained by the UE at least partially based on a reference signal.

[0102] Although Figure 5 example blocks of procedure 500 are shown, in some aspects, procedure 500 may include additional blocks, fewer blocks, different blocks, or differently arranged blocks compared to Figure 5 those shown. Additionally or alternatively, two or more of the blocks of procedure 500 may be executed in parallel.

[0103] Figure 6 FIG. 600 is a schematic diagram illustrating a data flow between different components in an example apparatus 602. The apparatus 602 may be a UE (e.g., UE 120). In some aspects, the apparatus 602 includes a transmitting component 604, a receiving component 606, a measuring component 608, etc.

[0104] The transmitting component 604 may send information indicating the L1 - SINR measurement capability of the apparatus 602 (e.g., to an apparatus 650 such as a base station 110). For example, in some aspects, the information indicating the L1 - SINR measurement capability may jointly indicate whether the apparatus 602 supports multiple configurations for one or more resources carrying reference signals. Additionally or alternatively, the information indicating the L1 - SINR measurement capability may separately indicate whether the apparatus 602 supports one or more individual configurations for one or more resources carrying reference signals. Additionally or alternatively, one or more resources in each configuration may include CMR, IMR, etc., and the information indicating the L1 - SINR measurement capability may separately indicate whether the apparatus 602 supports one or more configurations for CMR and / or IMR (e.g., configuring CMR and / or IMR as SSB, CSI - RS, etc.).

[0105] The receiving component 606 may receive reference signals (e.g., SSB, CSI - RS, etc.) carried on one or more resources (e.g., from the apparatus 650) at least partially based on the L1 - SINR measurement capability of the apparatus 602. The measuring component 608 may obtain one or more measurements at least partially based on the reference signals, and the transmitting component 604 may send a report including the one or more measurements (e.g., to the apparatus 650). For example, in some aspects, in a case where the L1 - SINR measurement capability indicates that the apparatus 602 supports one or more configurations for one or more resources (the one or more resources enabling L1 - SINR measurement), the one or more measurements may include an L1 - SINR measurement.

[0106] The apparatus 602 may include additional components that perform Figure 4 each block in the algorithm in the above - mentioned process 400, etc. Figure 4 Each block in the above - mentioned process 400, etc., may be performed by components, and the apparatus 602 may include one or more of those components. The components may be one or more hardware components specifically configured to implement the process / algorithm, one or more hardware components implemented by a processor configured to execute the process / algorithm, one or more hardware components stored in a computer - readable medium for the processor to implement, or some combination thereof.

[0107] Figure 6The number and arrangement of components shown are provided as an example. In practice, there may be additional components, fewer components, different components, or components in a different arrangement than those Figure 6 shown. Additionally, Figure 6 two or more components shown may be implemented within a single component, or Figure 6 a single component shown may be implemented as multiple, distributed components. Additionally or alternatively, Figure 6 a set of components (e.g., one or more components) shown may perform one or more functions described as being performed by Figure 6 another set of components shown.

[0108] Figure 7 FIG. 700 is a schematic diagram of an example 700 showing the data flow between different components in an example apparatus 702. The apparatus 702 may be a base station (e.g., base station 110). In some aspects, the apparatus 702 includes a receiving component 704, a resource configuration component 706, a transmitting component 708, etc.

[0109] The receiving component 704 may receive (e.g., from an apparatus 750 such as a UE 120) information indicating the L1 - SINR measurement capability of the apparatus 750. For example, in some aspects, the information indicating the L1 - SINR measurement capability may jointly indicate whether the apparatus 750 supports multiple configurations for one or more resources carrying reference signals. Additionally or alternatively, the information indicating the L1 - SINR measurement capability may separately indicate whether the apparatus 750 supports one or more individual configurations for one or more resources carrying reference signals. Additionally or alternatively, one or more resources in each configuration may include CMR, IMR, etc., and the information indicating the L1 - SINR measurement capability may separately indicate whether the apparatus 750 supports one or more configurations for CMR and / or IMR (e.g., configuring CMR and / or IMR as SSB, CSI - RS, etc.).

[0110] Accordingly, in some aspects, the resource configuration component 706 can configure and / or select one or more resources carrying reference signals at least in part based on the L1-SINR measurement capabilities of the device 750, and the transmission component 708 can transmit (e.g., to the device 750) the reference signals carried on the one or more resources at least in part based on the L1-SINR measurement capabilities of the device 750. Additionally, in some aspects, the reception component 704 can receive (e.g., from the device 750) a report including one or more measurements at least in part based on the reference signals.
