Description

[Technical field]

[0001] (CROSS REFERENCE TO RELATED APPLICATIONS) This patent application claims priority to U.S. Provisional Patent Application No. 63 / 268,180, entitled "SERVING CELL MEASUREMENT OBJECTS ASSOCIATED WITH ACTIVE BANDWIDTH PARTS," filed February 17, 2022, and U.S. Non-Provisional Patent Application No. 18 / 155,369, entitled "SERVING CELL MEASUREMENT OBJECTS ASSOCIATED WITH ACTIVE BANDWIDTH PARTS," filed January 17, 2023, which are expressly incorporated by reference herein.

[0002] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for serving cell measurement objects associated with active bandwidth portions (BWPs). [Background technology]

[0003] Wireless communication systems have been widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. 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 / LTE-Advanced is a set of extensions to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP®).

[0004] A wireless network may include one or more base stations that support communication for a user equipment (UE) or multiple UEs. A UE may communicate with a base station via downlink and uplink communications. "Downlink" (or "DL") refers to the communication link from a base station to a UE, and "uplink" (or "UL") refers to the communication link from the UE to a base station.

[0005] The above multiple access technologies have been adopted in various telecommunications standards to provide a common protocol that allows different UEs to communicate on a city, national, regional, and / or global scale. New Radio (NR), sometimes referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectral efficiency, lowering costs, improving services, utilizing new spectrum, and by using orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) (CP-OFDM) on the downlink and CP-OFDM and / or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, and by better integrating with other open standards that support beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to grow, further improvements in LTE, NR, and other radio access technologies remain useful. Summary of the Invention

[0011] In some implementations, a non-transitory computer-readable medium storing a set of instructions for wireless communication includes one or more instructions that, when executed by one or more processors of a network entity, cause the network entity to send a configuration to a UE indicating one or more measurement objects, where one measurement object of the one or more measurement objects indicates an SSB frequency within the configured BWP, and where a serving cell measurement object from the one or more measurement objects is based at least in part on an active BWP of the UE.

[0012] In some implementations, an apparatus for wireless communication comprises means for receiving a configuration from a network entity indicating one or more measurement objects, where one of the one or more measurement objects indicates an SSB frequency of a configured BWP, and means for determining from the one or more measurement objects a serving cell measurement object associated with an SSB frequency in an active BWP based at least in part on the active BWP of the apparatus.

[0019] Various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure may be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout the present disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Those skilled in the art should understand that the scope of the present disclosure is intended to encompass all aspects of the present disclosure disclosed herein, whether implemented independently of or in combination with any other aspects of the present disclosure. For example, an apparatus can be implemented or a method can be practiced using any number of the aspects described herein. Moreover, the scope of the present disclosure is intended to encompass such an apparatus or method that is practiced using other structures, functions, or structures and functions in addition to or other than the various aspects of the present disclosure described herein. It should be understood that any aspect of the present disclosure disclosed herein can be embodied by one or more elements of a claim.

[0020] Several aspects of a telecommunications system are now presented with reference to various devices and techniques, which are described in the detailed description that follows and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends on the particular application and design constraints imposed on the overall system.

[0021] Although aspects may be described herein using terminology commonly associated with 5G or New Radio (NR) radio access technology (RAT), aspects of the disclosure may be applicable to other RATs, such as 3G RATs, 4G RATs, and / or post-5G (e.g., 6G) RATs.

[0022] FIG. 1 illustrates an example of a wireless network 100 in accordance with the present disclosure. The wireless network 100 may be or include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, among other examples. The wireless network 100 may include one or more base stations 110 (shown as BS 110a, BS 110b, BS 110c, and BS 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. The base stations 110 are entities that communicate with the UEs 120. The base stations 110 (which may be referred to as BSs) may include, for example, NR base stations, LTE base stations, Node Bs, eNBs (e.g., in 4G), gNBs (e.g., in 5G), access points, and / or transmit / receive points (TRPs). Each base station 110 can provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" can refer to the coverage area of ​​a base station 110 and / or a base station subsystem serving that coverage area, depending on the context in which the term is used.

[0023] A base station 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a few kilometers in radius) and may allow unrestricted access by UEs 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by UEs 120 with an association with the femto cell (e.g., UEs 120 in a closed subscriber group (CSG)). A base station 110 for a macro cell may be referred to as a macro base station. A base station 110 for a pico cell may be referred to as a pico base station. A base station 110 for a femto cell may be referred to as a femto base station or a home base station. 1, BS 110a may be a macro base station for a macro cell 102a, BS 110b may be a pico base station for a pico cell 102b, and BS 110c may be a femto base station for a femto cell 102c. A base station may support one or multiple (e.g., three) cells.

[0024] In some aspects, the term "base station" (e.g., base station 110) or "network entity" may refer to an aggregated base station, a non-aggregated base station, an integrated access and backhaul (IAB) node, a relay node, and / or one or more components thereof. For example, in some aspects, a "base station" or a "network entity" may refer to a central unit (CU), a distributed unit (DU), a radio unit (RU), a Near-Real Time (Near-RT) RAN Intelligent Controller (RIC), or a Non-Real Time (Non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or a "network entity" may refer to one device configured to perform one or more functions, such as the functions described herein with respect to base station 110. In some aspects, the term "base station" or a "network entity" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, multiple different devices (which may be located at the same geographic location or different geographic locations) may each be configured to perform at least a portion of the functions or replicate the operation of at least a portion of the functions, and the term "base station" or "network entity" may refer to any one or more of those different devices. In some aspects, the term "base station" or "network entity" may refer to one or more virtual base stations and / or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network entity" may refer to one of the base station functions and not another base station function. In this manner, a single device may include two or more base stations.

[0025] In some embodiments, the cells may not necessarily be fixed, and the geographic area of ​​the cells may move according to the location of the base stations 110 that are mobile (e.g., mobile base stations). In some embodiments, the base stations 110 may be interconnected to each other and / or to one or more other base stations 110 or network nodes (not shown) within the wireless network 100 via various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transport network.

[0026] The wireless network 100 may include one or more relay stations. A relay station is an entity capable of receiving a data transmission from an upstream station (e.g., a base station 110 or a UE 120) and transmitting the data transmission to a downstream station (e.g., a UE 120 or a base station 110). A relay station may be a UE 120 that can relay a transmission for another UE 120. In the embodiment shown in FIG. 1, a BS 110d (e.g., a relay base station) may communicate with a BS 110a (e.g., a macro base station) and a UE 120d to facilitate communication between the BS 110a (e.g., a macro base station) and the UE 120d. A base station 110 that relays communication may be referred to as a relay station, a relay base station, a repeater, etc.

[0027] The wireless network 100 may be a heterogeneous network that includes different types of base stations 110, such as macro base stations, pico base stations, femto base stations, relay base stations, etc. These different types of base stations 110 may have different transmit power levels, different coverage areas, and / or different susceptibility to interference within the wireless network 100. For example, a macro base station may have a high transmit power level (e.g., 5-40 Watts), while the pico base stations, femto base stations, and relay base stations may have a lower transmit power level (e.g., 0.1-2 Watts).

[0028] A network controller 130 may be coupled to or in communication with a set of base stations 110 and may provide coordination and control for these base stations 110. The network controller 130 may communicate with the base stations 110 via backhaul communication links. The base stations 110 may communicate with each other directly or indirectly via wireless or wired backhaul communication links.

[0029] The UEs 120 may be dispersed throughout the wireless network 100, and each UE 120 may be fixed or mobile. The UEs 120 may include, for example, an access terminal, a terminal, a mobile station, and / or a subscriber unit. The UEs 120 may be a mobile phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smart watch, a smart clothes, a smart glasses, a smart wristband, a smart jewelry (e.g., a smart ring or a smart bracelet)), an entertainment device (e.g., a music device, a video device, and / or a satellite radio), a vehicle part or sensor, a smart meter / sensor, industrial manufacturing equipment, a global positioning system device, and / or any other suitable device configured to communicate over a wireless medium.

[0030] Some UEs 120 may be considered as machine-type communication (MTC) UEs or evolved or enhanced machine-type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, a robot, a drone, a remote device, a sensor, a meter, a monitor, and / or a location tag that may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet-of-Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. The UE 120 may be included within a housing that houses components of the UE 120, such as a processor component and / or a memory component. In some embodiments, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0031] Generally, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a particular RAT and may operate on one or more frequencies. The RAT may be referred to as a radio technology, an air interface, etc. The frequencies may be referred to as a carrier, a frequency channel, etc. To avoid interference between wireless networks of different RATs, each frequency may support a single RAT in a given geographic area. In some cases, NR networks or 5G RAT networks may be deployed.

[0032] In some embodiments, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more sidelink channels. For example, UEs 120 may communicate using peer-to-peer (P2P) communications, device-to-device (D2D) communications, vehicle-to-everything (V2X) protocols (which may include, e.g., vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such embodiments, UEs 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by base station 110.

[0033] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided by frequency or wavelength into various classes, bands, channels, etc. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency range designations FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). It should be understood that FR1 is often referred to (interchangeably) as a "sub-6 GHz" band in various documents and papers, although a portion of FR1 is higher than 6 GHz. A similar nomenclature issue may arise with respect to FR2, which is often referred to (interchangeably) as a "millimeter wave" band in documents and papers, even though it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) identified as a "millimeter wave" band by the International Telecommunications Union (ITU).

[0034] Frequencies between FR1 and FR2 are often referred to as mid-band frequencies. Recent 5G NR studies have identified operating bands for these mid-band frequencies as a frequency range designated FR3 (7.125 GHz to 24.25 GHz). Frequency bands included within FR3 may inherit FR1 and / or FR2 characteristics, and thus may in effect extend the features of FR1 and / or FR2 to the mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been identified as frequency ranges designated FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands is included within the EHF band.

[0035] With the above examples in mind, it should be understood that terms such as "sub-6 GHz," as used herein, unless otherwise specified, may broadly refer to frequencies that may be below 6 GHz, may be within FR1, or may include mid-band frequencies. Additionally, it should be understood that terms such as "millimeter wave," as used herein, unless otherwise specified, may broadly refer to frequencies that may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, may include mid-band frequencies, or may be within the EHF band. It is contemplated that frequencies included within these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0036] In some aspects, a UE (e.g., UE 120) may include a communications manager 140. As described in more detail elsewhere herein, the communications manager 140 may receive a configuration from a network entity indicating one or more measurement objects, where one of the measurement objects indicates a synchronization signal block (SSB) frequency of a configured bandwidth portion (BWP), and determine from the one or more measurement objects a serving cell measurement object associated with an SSB frequency in an active BWP based at least in part on the active BWP of the UE. Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0037] In some aspects, a network entity (e.g., base station 110) may include a communications manager 150. As described in more detail elsewhere herein, communications manager 150 may send a configuration to the UE indicating one or more measurement objects, where one measurement object of the one or more measurement objects indicates an SSB frequency at the configured BWP and one serving cell measurement object from the one or more measurement objects is based at least in part on the active BWP of the UE. Additionally or alternatively, communications manager 150 may perform one or more other operations described herein.

[0038] As noted above, Figure 1 is provided as an example. Other implementations may differ from those described with respect to Figure 1.

[0039] 2 illustrates an example base station 200 in communication with a UE 120 in a wireless network 100 in accordance with the present disclosure. The base station 110 may be equipped with a set of antennas 234a through 234t, such as T antennas, where T≧1. The UE 120 may be equipped with a set of antennas 252a through 252r, such as R antennas, where R≧1.

[0040] At the base station 110, a transmit processor 220 may receive data intended for a UE 120 (or set of UEs 120) from a data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCSs) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The base station 110 may process (e.g., encode and modulate) data for the UE 120 based at least in part on the MCS(es) selected for the UE 120 and provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., related to semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or higher layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for a reference signal (e.g., a cell-specific reference signal (CRS) or a demodulation reference signal (DMRS)) and a synchronization signal (e.g., a primary synchronization signal (PSS) or a secondary synchronization signal (SSS)). A transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on ​​the data symbols, control symbols, overhead symbols, and / or reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems), which are illustrated as modems 232a through 232t.For example, each output symbol stream may be provided to a modulator component (denoted as MOD) of modem 232. Each modem 232 may process (e.g., for OFDM) its respective output symbol stream using a respective modulator component to obtain an output sample stream. Each modem 232 may further process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream using a respective modulator component to obtain a downlink signal. Modems 232a through 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas), denoted as antennas 234a through 234t.

[0041] At the UE 120, a set of antennas 252 (depicted as antennas 252a through 252r) may receive downlink signals from the base station 110 and / or other base stations 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems), depicted as modems 254a through 254r. For example, each received signal may be provided to a demodulator component (depicted as DEMOD) of the modems 254. Each modem 254 may condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal using a respective demodulator component to obtain input samples. Each modem 254 may further process the input samples (e.g., for OFDM) using the demodulator component to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modems 254, perform MIMO detection on the received symbols, if applicable, and provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, provide decoded data for the UE 120 to a data sink 260, and provide decoded control and system information to a controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other examples. In some embodiments, one or more components of the UE 120 may be included within a housing 284.

[0042] 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 stations 110 via the communication unit 294.

[0043] One or more antennas (e.g., antennas 234a-t and / or antennas 252a-r) may include or be contained within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, among other examples. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include (in a single housing or multiple housings) one or more antenna elements, a set of coplanar antenna elements, a set of non-coplanar antenna elements, and / or one or more antenna elements coupled to one or more transmitting and / or receiving components, such as one or more components of FIG.

[0044] On the uplink, in the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI) from the controller / processor 280. The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be precoded by the TX MIMO processor 266, if applicable, and may be further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM) and transmitted to the base station 110. In some embodiments, the modem 254 of the UE 120 may include a modulator and a demodulator. In some embodiments, the UE 120 includes a transceiver. The transceiver may include any combination of the antenna(s) 252, the modem(s) 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, and / or the TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., with reference to Figures 7-11).

[0045] At the base station 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component of the modem 232, denoted as DEMOD), detected by a MIMO detector 236, if applicable, and further processed by a receive processor 238 to obtain decoded data and control information transmitted by the UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to the controller / processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The base station 110 may include a scheduler 246 for scheduling one or more UEs 120 for downlink and / or uplink communications. In some embodiments, the modem 232 of the base station 110 may include a modulator and a demodulator. In some embodiments, the base station 110 includes a transceiver. The transceiver may include any combination of antenna(s) 234, modem(s) 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., with reference to FIGS. 7-11).

[0046] The controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or any other component(s) of FIG. 2 may perform one or more techniques associated with a serving cell measurement object associated with an active BWP, as described in more detail elsewhere herein. For example, the controller / processor 240 of the base station 110, the controller / processor 280 of the UE 120, and / or any other component(s) of FIG. 2 may perform or direct the operation of, for example, process 800 of FIG. 8, process 900 of FIG. 9, and / or other processes as described herein. The memory 242 and the memory 282 may store data and program codes for the base station 110 and the UE 120, respectively. In some embodiments, the memory 242 and / or the memory 282 may include a non-transitory computer-readable medium that stores one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of the base station 110 and / or the UE 120 (e.g., directly or after compiling, translating, and / or interpreting), may cause the one or more processors, the UE 120, and / or the base station 110 to perform or direct operations of, for example, process 800 of FIG. 8, process 900 of FIG. 9, and / or other processes as described herein. In some embodiments, executing the instructions may include running the instructions, translating the instructions, compiling the instructions, and / or interpreting the instructions, among other examples.

[0047] In some aspects, a UE (e.g., UE 120) comprises means for receiving from a network entity a configuration indicating one or more measurement objects, where one of the one or more measurement objects indicates an SSB frequency of a configured BWP, and / or means for determining from the one or more measurement objects a serving cell measurement object associated with an SSB frequency in an active BWP based at least in part on the active BWP of the UE. Means for causing a UE to perform operations described herein may include, for example, one or more of communications manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller / processor 280, or memory 282.

[0048] In some aspects, a network entity (e.g., base station 110) includes means for transmitting a configuration to the UE indicating one or more measurement objects, where one measurement object of the one or more measurement objects indicates an SSB frequency within the configured BWP, and a serving cell measurement object from the one or more measurement objects is based at least in part on the active BWP of the UE. In some aspects, the means for causing the network entity to perform the operations described herein may include, for example, one or more of the communications manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antennas 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0049] 2 are shown as separate components, the functionality described above with respect to the blocks may be implemented in a single hardware, software, or combination component, or in various combinations of components. For example, functionality described with respect to transmit processor 264, receive processor 258, and / or TX MIMO processor 266 may be performed by or under the control of controller / processor 280.

[0050] As noted above, Figure 2 is provided as an example. Other implementations may differ from those described with respect to Figure 2.

[0051] FIG. 3 is a diagram illustrating an example disaggregated base station architecture 300 in accordance with the present disclosure.

[0052] The deployment of a communication system such as a 5G NR system can be configured in multiple ways with various components or components. In a 5G NR system or network, a network node, network entity, mobility element of the network, RAN node, core network node, network element, or network equipment such as a base station (BS, e.g., base station 110), or one or more units (or one or more components) performing base station functions, can be implemented in an aggregated or non-aggregated architecture. For example, a BS (such as a Node B (NB), eNB, NR BS, 5G NB, access point (AP), TRP, or cell) can be implemented as an aggregated base station (also known as a standalone BS or monolithic BS) or a non-aggregated base station.

[0053] An aggregated base station may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node. A non-aggregated base station may be configured to utilize a protocol stack that is physically or logically distributed between two or more units (e.g., one or more CUs, one or more DUs, or one or more RUs). In some aspects, a CU may be implemented within a RAN node, and one or more DUs may be co-located with the CU, or alternatively, may be geographically or virtually distributed across one or more other RAN nodes. A DU may be implemented to communicate with one or more RUs. Each of the CU, DU, and RU may also be implemented as a virtual unit, i.e., a virtual centralized unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU).

[0054] The operation of a base station type or network design may take into account the aggregation characteristics of the base station functions. For example, a non-aggregated base station may be utilized in an IAB network, an O-RAN (such as a network configuration sponsored by the O-RAN Alliance), or a virtualized radio access network (vRAN, also known as a Cloud Radio Access Network (C-RAN)). Non-aggregation may include distributing functions across two or more units in various physical locations, as well as distributing functions virtually for at least one unit, which may allow flexibility in network design. Various units of a non-aggregated base station, or a non-aggregated RAN architecture, may be configured for wired or wireless communication with at least one other unit.

[0055] The disaggregated base station architecture shown in FIG. 3 may include one or more CUs 310 that may communicate directly with the core network 320 via a backhaul link or indirectly with the core network 320 through one or more disaggregated base station units (such as a quasi-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CUs 310 may communicate with one or more DUs 330 via respective midhaul links, such as an F1 interface. The DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. The RUs 340 may communicate with respective UEs 120 via one or more radio frequency (RF) access links. In some implementations, a UE 120 may be served by multiple RUs 340 simultaneously.

[0056] Each of the units (e.g., CU 310, DU 330, RU 340), as well as quasi-RT RIC 325, non-RT RIC 315, and SMO framework 305, may include or be coupled to one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) over a wired or wireless transmission medium. Each of the units, or an associated processor or controller that provides instructions to the unit's communication interface, may be configured to communicate with one or more of the other units over a transmission medium. For example, a unit may include a wired interface configured to receive or transmit signals to one or more of the other units over a wired transmission medium. In addition, a unit may include a wireless interface, which may include a receiver, transmitter, or transceiver (such as an RF transceiver), configured to receive and / or transmit signals to one or more of the other units over the wireless transmission medium.

[0057] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP), Service Data Adaptation Protocol (SDAP), and the like. Each control function may be implemented with an interface configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functions (e.g., Central Unit-User Plane (CU-UP)), control plane functions (e.g., Central Unit-Control Plane (CU-CP)), or a combination thereof. In some implementations, the CU 310 may be logically divided into one or more CU-UP units and one or more CU-CP units. The CU-UP units, when implemented in an O-RAN configuration, may communicate bidirectionally with the CU-CP units via an interface, such as an E1 interface. The CU 310 may be implemented to communicate with the DU 330, as necessary, for network control and signaling.

[0058] The DU 330 may correspond to a logical unit including one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a medium access control (MAC) layer, and one or more upper physical (PHY) layers (such as modules for forward error correction (FEC) encoding and decoding, scrambling, modulation, demodulation, etc.), at least in part according to a functional division such as that defined by 3GPP. In some aspects, the DU 330 may further host one or more lower PHY layers. Each layer (or module) may be implemented with an interface configured to communicate signals with other layers (and modules) hosted by the DU 330 or with a control function hosted by the CU 310.

[0059] The lower layer functions may be implemented by one or more RUs 340. In some deployments, the RUs 340 controlled by the DU 330 may correspond to logical nodes hosting RF processing functions, or lower PHY layer functions (such as performing fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, physical random access channel (PRACH) extraction and filtering, etc.), or both, based at least in part on a functional division such as a lower layer functional division. In such an architecture, the RU(s) 340 may be implemented to handle over the air (OTA) communications with one or more UEs 120. In some implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU(s) 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable the DU(s) 330 and the CU 310 to be implemented in a cloud-based RAN architecture, such as a vRAN architecture.

[0060] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support deployment of dedicated physical resources for RAN coverage requirements that can be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-cloud) 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, the CU 310, the DU 330, the RU 340, and the quasi-RT RIC 325. In some implementations, the SMO framework 305 may communicate with hardware aspects of a 4G RAN, such as an open eNB (O-eNB) 311, via an O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with one or more RUs 340 via an O1 interface. The SMO framework 305 may also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0061] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updates, or policy-based guidance of applications / features in the quasi-RT RIC 325. The non-RT RIC 315 may be coupled to or in communication with the quasi-RT RIC 325 (e.g., via an A1 interface). The quasi-RT RIC 325 may be configured to include logic functions that enable near real-time control and optimization of RAN elements and resources by data collection and action over interfaces (e.g., via an E2 interface) that connect one or more CUs 310, one or more DUs 330, or both, and the O-eNB to the quasi-RT RIC 325.

[0062] In some implementations, the non-RT RIC 315 may receive parameters or external enrichment information from an external server to generate an AI / ML model to be deployed to the quasi-RT RIC 325. Such information may be utilized by the quasi-RT RIC 325 or may be received from a non-network data source or from a network function in the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the quasi-RT RIC 325 may be configured to adjust RAN behavior or performance. For example, the non-RT RIC 315 may employ the AI / ML model to monitor long-term trends and patterns in performance and take corrective action through the SMO framework 305 (e.g., reconfiguration via O1) or through the creation of RAN management policies (e.g., A1 policies).

[0063] As noted above, Figure 3 is provided as an example, other implementations may differ from those described with respect to Figure 3.

[0064] A network entity may send a serving cell configuration (ServingCellConfig) to a UE to configure a serving cell for the UE. The serving cell configuration may indicate an initialDownlinkBWP parameter, a downlinkBWP-ToReleaseList parameter to release a list, a downlinkBWP-ToAddModList parameter to modify a list, and a serving cell measurement object (MO) (servingCellMO). The serving cell measurement object may indicate a measurement object identifier (ID) (MeasObjectId) of a measurement object NR (MeasObjectNR) in a measurement configuration (MeasConfig) associated with the serving cell. The network may send a measurement object NR to the UE to configure a measurement object for the UE in NR. The measurement object NR may indicate an SSB Frequency (ssbFrequency), which may indicate a frequency of a Synchronization Signal (SS) associated with the measurement object NR. Furthermore, the serving cell measurement object does not need to be dependent on the UE's active BWP and does not need to change when the UE's BWP changes.

[0065] A neighbor cell SSB may be intra-frequency if it aligns with the reference SSB of the serving cell and the subcarrier spacing of the neighbor cell SSB and the reference SSB is the same. A neighbor cell may be inter-frequency if it does not align with the reference SSB of the serving cell and the subcarrier spacing of the neighbor cell SSB and the reference SSB is not the same. Intra-frequency cell identification and measurement period may be different from inter-frequency cell identification and measurement period. The UE may identify or measure a larger amount of samples for inter-frequency cells compared to intra-frequency cells.

[0066] A network entity may identify whitelisted and blacklisted cells, and the network entity may signal an indication to the UE indicating the whitelisted and blacklisted cells. A whitelisted cell corresponding to a measurement object may refer to a cell that transmits SSB on the frequency of the measurement object. A whitelisted cell may refer to a cell that should be measured by the UE. The network entity may indicate to the UE to measure the whitelisted cell. A blacklisted cell corresponding to a measurement object may refer to a cell that should not be measured by the UE. The network entity may indicate to the UE not to measure the blacklisted cell.

[0067] FIG. 4 is a diagram illustrating an example 400 of different BWPs for a reduced capability UE in accordance with the present disclosure.

[0068] In some aspects, a network entity may serve different UEs of different categories and / or different UEs supporting different capabilities. For example, a network entity may serve a first category of UEs having less advanced capabilities (e.g., lower and / or reduced capabilities) and a second category of UEs having more advanced capabilities (e.g., higher capabilities). The first category of UEs may have a reduced feature set compared to the second category of UEs and may also be referred to as reduced capability (RedCap) UEs, low tier UEs, and / or NR-Lite UEs, among other examples. The first category of UEs may be, for example, MTC UEs, eMTC UEs, and / or IoT UEs, as described above in connection with FIG. 1. The second category of UEs may have an advanced feature set compared to the second category of UEs and may also be referred to as baseline UEs, high tier UEs, NR UEs, and / or premium UEs, among other examples. In some aspects, a first category of UE has the capability to meet the requirements of a first (earlier) wireless communications standard but not a second (later) wireless communications standard, while a second category of UE has the capability to meet the requirements of the second (later) wireless communications standard (and possibly the first wireless communications standard as well).

[0069] For example, the first category UEs may support a lower maximum MCS than the second category UEs (e.g., quadrature phase shift keying (QPSK) as compared to 256 quadrature amplitude modulation (QAM)), support a lower maximum transmit power than the second category UEs, have less advanced beamforming capabilities than the second category UEs (e.g., may not be able to form as many beams as the second category UEs), require more processing time than the second category UEs, include less hardware (e.g., fewer antennas, fewer transmit antennas, and / or fewer receive antennas) than the second category UEs, and / or may not be able to communicate over the same wide maximum bandwidth portion as the second category UEs, among other examples. Additionally or alternatively, the second category of UEs may be capable of communicating using a shortened transmission time interval (TTI) (e.g., slot lengths of 1 millisecond (ms) or less, 0.5 ms, 0.25 ms, 0.125 ms, 0.0625 ms, etc., depending on the subcarrier spacing) and the first category of UEs may not be capable of communicating using a shortened TTI.

[0070] As shown in FIG. 4, multiple different BWPs may be used for reduced and non-reduced capability UEs. The first BWP 402 may be a reduced capability RRC uplink BWP#2 and may span 5 MHz. The second BWP 404 may be a reduced capability RRC downlink BWP#2 and may span 5 MHz. The second BWP 404 may be a BWP configured for low power mode. The second BWP 404 may not include a cell-defined SSB (CD-SSB). The second BWP 404 may or may not include a non-cell-defined SSB (NCD-SSB). The third BWP 406 may be a reduced capability RRC uplink BWP#1 and may span 20 MHz. The fourth BWP 408 may be a reduced capability RRC downlink BWP#1 and may span 20 MHz. The fourth BWP 408 may be a BWP configured for normal active operation. The fourth BWP 408 may not include a CD-SSB. The fourth BWP 408 may or may not include a NCD-SSB. The fifth BWP 410 may be an RRC configured uplink BWP#1 of unreduced capability and may span 100 MHz. The sixth BWP 412 may be an RRC configured downlink BWP#1 of unreduced capability and may span 100 MHz. The seventh BWP 414 may be an initial uplink BWP of unreduced capability and may span 100 MHz. The eighth BWP 416 may be an initial downlink BWP of unreduced capability and may span 20 MHz and may include a CD-SSB and a control resource set (CORESET). The ninth BWP 418 may be an initial uplink BWP of reduced capability and may span 20 MHz. The tenth BWP 420 may be a reduced capacity initial downlink BWP and may span 20 MHz.

[0071] As noted above, Figure 4 is provided as an example. Other implementations may differ from that described with respect to Figure 4.

[0072] FIG. 5 is a diagram illustrating an example 500 of CD-SSB and NCD-SSB in accordance with the present disclosure.

[0073] As shown in FIG. 5, the CD-SSB may be located at a synchronization raster point, and the NCD-SSB may be located off the synchronization raster point. The CD-SSB may be associated with the system information (SI) of the cell, while the NCD-SSB may not be associated with the SI of the cell. A master information block (MIB) or a system information block (SIB) may indicate a CORESET (e.g., CORESET0) associated with the CD-SSB. The CD-SSB and the NCD-SSB may be quasi-co-located and may have the same physical cell identifier (PCI). The CD-SSB and the NCD-SSB may be associated with different periodicities and different transmit powers. Furthermore, the CD-SSB and the NCD-SSB may be associated with different uplink transmit powers, different selected random access channel (RACH) occasions, and / or different measurement periods.

[0074] As noted above, Figure 5 is provided as an example. Other implementations may differ from those described with respect to Figure 5.

[0075] FIG. 6 is a diagram illustrating an example 600 of CD-SSB and NCD-SSB for reduced capability UEs in accordance with the present disclosure.

[0076] A reduced capability UE may be configured with a different RRC BWP. If a reduced capability UE requires NCD-SSB, each RRC BWP may have at least CD-SSB or NCD-SSB. If a reduced capability UE does not require NCD-SSB, the RRC BWP may include only a channel state information reference signal (CSI-RS) and may not include an SSB. Furthermore, the NCD-SSB of a neighbor cell (NCell) in the same frequency may be located at different frequency positions.

[0077] As shown in Figure 6, the configured RRC BWP#1 (e.g., active BWP) may be associated with the NCD-SSB of the serving cell and the NCD-SSB of the first intra-frequency neighboring cell (NCell1). The initial downlink BWP may be associated with the CD-SSB of the serving cell, the CD-SSB of NCell1, the CD-SSB of the second intra-frequency neighboring cell (NCell2), and the CD-SSB of the third intra-frequency neighboring cell (NCell3), and the NCD-SSB may not be transmitted by NCell3. The configured RRC BWP#2 may be associated with the NCD-SSB of the serving cell and the NCD-SSB of NCell2.

[0078] As noted above, Figure 6 is provided as an example, other implementations may differ from those described with respect to Figure 6.

[0079] In legacy NR, a network entity may configure a UE with a serving cell measurement object that includes the frequency location of the SSB. The frequency location may include the intra-frequency location of the SSB and / or the inter-frequency location of the SSB. However, the serving cell measurement object may be independent of the location of the UE's active BWP. Because the serving cell measurement object is independent of the location of the UE's active BWP, the serving cell measurement object is not changed when the UE switches between BWPs, which may cause the UE to perform inaccurate SSB frequency measurements after a BWP switch or cause the UE to not perform SSB frequency measurements after a BWP switch.

[0080] In various aspects of the techniques and apparatus described herein, the UE may receive a configuration from a network entity indicating one or more measurement objects. One measurement object (e.g., each measurement object) of the one or more measurement objects may indicate an SSB frequency of a configured BWP. The UE may determine a serving cell measurement object from the one or more measurement objects based at least in part on an active BWP of the UE. The serving cell measurement object may be associated with an SSB frequency in the active BWP. In some aspects, the active BWP of the UE may be a first BWP, and the UE may perform BWP switching from the first BWP to a second BWP. Based at least in part on the BWP switching, the first BWP may become inactive and the second BWP may become active. In some aspects, the UE may autonomously determine an updated serving cell measurement object based at least in part on the second BWP from the one or more measurement objects and based at least in part on the BWP switching. The updated serving cell measurement object may be associated with an SSB frequency in the second BWP. Since the UE may determine the updated serving cell measurement object without instructions from a network entity, the UE may determine the updated serving cell measurement object autonomously. Alternatively, the UE may receive signaling from the network entity and based at least in part on the BWP switching, instructing the UE to determine an updated serving cell measurement object from one or more measurement objects based at least in part on the second BWP.

[0081] In some aspects, a network entity may configure a UE (e.g., a reduced capability UE) with multiple SSBs across a configured BWP (e.g., one SSB in each of the UE's configured BWPs). The network entity may configure a measurement object within the same frequency that includes frequency locations of multiple NCD-SSBs (e.g., all NCD-SSBs), or the network entity may configure multiple measurement objects within the same frequency, with each measurement object including the frequency location of one of the NCD-SSBs.

[0082] In some aspects, the serving cell measurement object of the UE may be based at least in part on the active BWP of the UE. After BWP switching (e.g., the UE moves from an old BWP to a new active BWP), the UE may autonomously update the serving cell measurement object and the corresponding measurement object ID (or serving cell measurement object ID) to be the measurement object ID of the measurement object associated with the SSB in the new active BWP of the UE. In other words, the BWP switching may trigger the UE to autonomously update the serving cell measurement object ID. As a result, the UE can perform SSB frequency measurements after the BWP switching.

[0083] Alternatively, based at least in part on the BWP switching, the network entity may send signaling to the UE instructing the UE to update the serving cell measurement object and the corresponding measurement object ID to the measurement object ID of the measurement object associated with the SSB in the UE's new active BWP. The network entity may perform the signaling using RRC or a medium access control control element (MAC-CE). However, the UE autonomously updating the serving cell measurement object and the corresponding measurement object ID without explicit signaling from the network entity may reduce signaling overhead.

[0084] In some aspects, the UE may require a minimum time to autonomously update the serving cell measurement object ID, which may be different from the BWP switching delay. The network entity may configure both CD-SSB and NCD-SSB in the measurement object of the intra-frequency NCell SSB. Furthermore, when the UE updates the serving cell measurement object based at least in part on the BWP switching, the identification / measurement requirements for the NCell and whitelisted / blacklisted cells corresponding to the serving cell measurement object may be updated based at least in part on the BWP switching.

[0085] 7 is a diagram illustrating an example 700 associated with a serving cell measurement object associated with an active BWP in accordance with the present disclosure. As shown in FIG. 7, the example 700 includes communication between a UE (e.g., UE 120) and a network entity (e.g., base station 110). In some aspects, the UE and the network entity may be included within a wireless network, such as wireless network 100.

[0086] In some aspects, the UE may be a reduced capability UE. Reduced capability UEs may refer to a group of UEs that have a smaller maximum UE RF bandwidth than other NR UEs that would operate in the same channel as these reduced capability UEs. As an example, the maximum RF bandwidth for reduced capability UEs may be 20 MHz in FR1 and 100 MHz in FR2.

[0087] As indicated by reference numeral 702, the UE may receive a configuration from a network entity indicating one or more measurement objects. One measurement object (e.g., each measurement object) of the one or more measurement objects may indicate an SSB frequency of a configured BWP. The SSB frequency associated with the measurement object may be an NCD-SSB frequency of the configured BWP or a CD-SSB frequency of the configured BWP. In other words, the UE may be configured with multiple measurement objects in the same frequency, and each measurement object may indicate a CD-SSB / NCD-SSB location of a different configured BWP. In some aspects, the network entity may configure the UE with multiple SSBs (e.g., one SSB in each of the UE's configured BWPs) across the configured BWPs. The network entity may configure a measurement object in the same frequency that includes frequency locations of multiple NCD-SSBs (e.g., all NCD-SSBs), or the network entity may configure multiple measurement objects in the same frequency, and each measurement object may include a frequency location of one of those NCD-SSBs.

[0088] As indicated by reference numeral 704, the UE may determine a serving cell measurement object from one or more measurement objects based at least in part on the active BWP of the UE. In other words, the serving cell measurement object of the UE may be based at least in part on the location of the active BWP of the UE. The serving cell measurement object may be a measurement object associated with the serving cell of the UE. The serving cell measurement object may be associated with an SSB frequency within the active BWP. If the active BWP does not include an NCD-SSB (or excludes an NCD-SB), the CD-SSB may be associated with the serving cell measurement object, or the CD-SSB may be the default serving cell measurement object. In some aspects, the UE may select a measurement object from one or more measurement objects to act as the serving cell measurement object, and the UE may select the measurement object based at least in part on the BWP associated with the measurement object corresponding to the active BWP of the UE. In some aspects, the serving cell measurement object may be associated with a reference SSB of the serving cell of the UE. The reference SSB may be an NCD-SSB within the active BWP, or the reference SSB may be an SSB inside or outside the active BWP.

[0089] As indicated by reference numeral 706, the active BWP of the UE may be a first BWP, and the UE may perform BWP switching from the first BWP to a second BWP. Based at least in part on the BWP switching, the first BWP may become inactive and the second BWP may become active. In some aspects, the UE may perform BWP switching based at least in part on signaling from a network entity, or the UE may perform BWP switching based at least in part on expiration of a timer. For example, the UE may perform BWP switching based at least in part on downlink control information (DCI), RRC signaling, or MAC-CE received from the network entity.

[0090] As indicated by reference numeral 708, the UE may determine an updated serving cell measurement object based at least in part on the second BWP from the one or more measurement objects and based at least in part on the BWP switching, and the updated serving cell measurement object may be associated with an SSB frequency in the second BWP. In some aspects, the UE may determine the updated serving cell measurement object autonomously. When the UE changes between BWPs, the UE may autonomously update the serving cell measurement object. In this case, the UE may determine the updated serving cell measurement object without being instructed by the network. Alternatively, the UE may receive signaling from a network entity and based at least in part on the BWP switching instructing the UE to determine an updated serving cell measurement object based at least in part on the second BWP from the one or more measurement objects.

[0091] In some aspects, a network entity may instruct the UE to update the serving cell measurement object after BWP switching. The network entity may instruct the UE to update the serving cell measurement object via DCI, RRC signaling, or MAC-CE. However, updating the serving cell measurement object based at least in part on an instruction from the network entity may involve increased signaling overhead compared to the UE autonomously updating the serving cell measurement object after BWP switching.

[0092] In some aspects, after BWP switching (e.g., after the UE moves from an old BWP to a new active BWP), the UE may update the serving cell measurement object and the corresponding measurement object ID (or serving cell measurement object ID) to be the measurement object ID of the measurement object associated with the SSB in the UE's new active BWP. In other words, the BWP switching may trigger the UE to update the serving cell measurement object ID. As a result, the UE can perform SSB frequency measurements after the BWP switching.

[0093] In some aspects, the UE may determine an updated serving cell measurement object from one or more measurement objects according to a time duration different from the BWP switching delay. In some aspects, the time required for the UE to update the serving cell measurement object may be different from the BWP switching delay. For example, the DCI-based BWP switching delay may be 2.50 ms, but the UE may need 4 ms to update the serving cell measurement object. The UE may ignore performing measurements during the transition period to the updated serving cell measurement object.

[0094] In some aspects, the UE may determine whether the reference SSB of the neighboring cell is an intra-frequency SSB or an inter-frequency SSB based at least in part on the BWP switching. The UE may identify and measure the reference SSB of the neighboring cell within a time period. The time period may be based at least in part on whether the reference SSB of the neighboring cell is an intra-frequency SSB or an inter-frequency SSB. The time period for identifying and measuring the inter-frequency SSB may be longer than the time period for identifying and measuring the intra-frequency SSB.

[0095] In some aspects, depending on the reference SSB change of the serving cell due to BWP switching, the reference SSB of the neighbor cell can be an intra-frequency SSB or an inter-frequency SSB. As an example, by using FIG. 6 as a reference, in RRC BWP#1, only the NCD-SSB of NCell1 may be an intra-frequency SSB, and all other NCell SSBs may be inter-frequency SSBs. In RRC BWP#2, only the NCD-SSB of NCell2 may be an intra-frequency SSB, and all other NCell SSBs may be inter-frequency SSBs. Depending on the reference SSB change of the serving cell, the identification and measurement delay requirement of the neighbor cell SSBs may be autonomously changed in the UE accordingly.

[0096] In some aspects, the UE may determine the whitelisted cells associated with the serving cell measurement object based at least in part on the BWP switching. In some aspects, upon BWP switching and corresponding changes to the reference SSB of the serving cell, the whitelisted cells corresponding to the serving cell measurement object may be changed autonomously at the UE accordingly. As an example, by using FIG. 6 as a reference, in the initial downlink BWP, the whitelisted cells may be NCell1, NCell2, and NCell3. In the RRC configured BWP#1, the whitelisted cell may be only the cell NCell1. In the RRC configured BWP#2, the whitelisted cell may be only the cell NCell2.

[0097] In some aspects, the network entity may determine whether the reference SSB of the neighbor cell will be an intra-frequency SSB or an inter-frequency SSB based at least in part on the BWP switching at the UE. The network entity may transmit an indication to the UE indicating whether the reference SSB of the neighbor cell will be an intra-frequency SSB or an inter-frequency SSB. In some aspects, the network entity may determine whitelisted cells associated with the serving cell measurement object based at least in part on the BWP switching at the UE. The UE may transmit an indication of whitelisted cells associated with the serving cell measurement object to the UE.

[0098] As noted above, Figure 7 is provided as an example. Other implementations may differ from those described with respect to Figure 7.
