The disclosures of these prior applications are considered part of and incorporated by reference into this patent application. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for non-cell defining synchronization signals and physical broadcast channel block configuration. Background Art

[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support 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 enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).

[0005] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, among other examples).

[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR) (which may be referred to as 5G) is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with cyclic prefix (CP) on the downlink, using 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 supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation, so as to better support mobile broadband Internet access. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful. Summary of the invention

[0026] The various aspects of the present disclosure are described more fully below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms, and should not be construed as being limited to any specific structure or function presented throughout the present disclosure. Instead, these aspects are provided so that the present disclosure will be thorough and complete, and the protection scope of the present disclosure will be fully conveyed to those skilled in the art. It should be understood by those skilled in the art that the scope of the present disclosure is intended to cover any aspect of the disclosure disclosed herein, whether it is implemented independently or in combination with any other aspect of the present disclosure. For example, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods implemented using other structures, functionality, or structures and functionality in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0027] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0028] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applicable to other RATs, such as 3G RAT, 4G RAT, and / or post-5G RATs (e.g., 6G).

[0029] Figure 11 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network or may include elements of a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 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 entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). As another example, the network node 110 may be a decomposed network node (sometimes referred to as a decomposed base station), which means that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed between two or more nodes (such as one or more central units (CUs), one or more distributed units (DUs), or one or more radio units (RUs)).

[0030] In some examples, the network node 110 is or includes a network node (such as an RU) that communicates with the UE 120 via a radio access link. In some examples, the network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, the network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. The network node 110 may include, for example, an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul, midhaul, and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks, using any suitable transport network.

[0031] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of ​​the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 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 radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 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 a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1 In the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. A network node may support one or more (e.g., three) cells. In some examples, a cell may not necessarily be stationary, and the geographic area of ​​a cell may move depending on the location of a mobile network node 110 (e.g., a mobile network node).

[0032] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a 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 "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with network node 110). In some aspects, the term "base station" or "network node" may refer to multiple devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations 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 node" may refer to one of the base station functions but not the other. In this way, a single device may include more than one base station.

[0033] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. Figure 1 In the example shown, a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communication between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.

[0034] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).

[0035] The network controller 130 may be coupled to or in communication with a collection of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless or wired backhaul communication link. In some aspects, the network controller 130 may be, or may include, a CU or a core network device.

[0036] UE 120 can be distributed throughout the wireless network 100, and each UE 120 can be stationary or mobile. UE 120 can include, for example, an access terminal, a terminal, a mobile station and / or a subscriber unit. UE 120 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 device, 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, smart clothing, smart glasses, a smart wristband, 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 component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node and / or any other suitable device configured to communicate via a wireless or wired medium.

[0037] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and / or location tags, which may communicate with a network node, 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. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, 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., a memory) may be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0038] In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

[0039] In some examples, 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 network node 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.

[0040] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., according to frequency or wavelength. 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 ranges designated FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be understood that although portions of FR1 are greater than 6 GHz, FR1 is often (interchangeably) referred to as the "below 6 GHz" band in various documents and articles. A similar naming problem sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0041] Frequencies between FR1 and FR2 are generally referred to as mid-band frequencies. Recent 5G NR research has identified the operating bands for these mid-band frequencies as frequency range designation FR3 (7.125GHz-24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, currently higher frequency bands are being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz-71GHz), FR4 (52.6GHz-114.25GHz) and FR5 (114.25GHz-300GHz). Each of these higher frequency bands falls within the EHF band.

[0042] Considering the above examples, unless otherwise specifically stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in 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.

[0043] In some aspects, the UE 120 may include a communications manager 140. As described in more detail elsewhere herein, the communications manager 140 may receive a non-cell defined (NCD) synchronization signal and a physical broadcast channel (PBCH) block (SSB) (NCD-SSB) configuration indicating one or more parameters for transmission via at least one NCD-SSB burst corresponding to at least one NCD-SSB set associated with at least one cell, the at least one cell including at least one of a primary cell or a secondary cell; and receive the at least one NCD-SSB burst based at least in part on the NCD-SSB configuration. Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0044] In some aspects, a network node (e.g., network node 110) may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send an NCD-SSB configuration indicating one or more NCD-SSB parameters corresponding to transmission of at least one NCD-SSB associated with at least one cell, the at least one cell including at least one of a primary cell or a secondary cell; and send the at least one NCD-SSB to the UE based at least in part on the NCD-SSB configuration. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0045] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 Different from what is described.

[0046] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0047] At the network node 110, a transmit processor 220 may receive data intended for a UE 120 (or a set of UEs 120) from a data source 212. The transmit processor 220 may select one or more modulation and coding schemes (MCS) for the UE 120 based at least in part on one or more channel quality indicators (CQIs) received from the UE 120. The network node 110 may process (e.g., encode and modulate) the data for the UE 120 based at least in part on the MCS selected for the UE 120, and may provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource allocation information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-coding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, where 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) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and / or upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a through 232t may transmit a set of downlink signals (eg, T downlink signals) via a corresponding set of antennas 234 (eg, T antennas) (shown as antennas 234a through 234t).

[0048] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide 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) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0049] 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 network node 110 via the communication unit 294.

[0050] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included 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, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or may be coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.

[0051] 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 reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and sent to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, with reference to Figures 5 to 9 ) or any aspect of any of the methods described herein.

[0052] At the network node 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 (shown as DEMOD) of the modem 232), detected by the MIMO detector 236 (where applicable), and further processed by the 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 the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink communication and / or uplink communication. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 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 operations described herein (e.g., with reference to Figures 5 to 9 ) or any aspect of any of the methods described herein.

[0053] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component in the network node 110 may perform one or more techniques associated with NCD-SSB configuration, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 6 The process of 600 Figure 7 700 and / or operations of other processes as described herein. Memory 242 and memory 282 may store data and program codes for network node 110 and UE 120, respectively. In some examples, memory 242 and / or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed (e.g., directly, or after compilation, conversion, and / or interpretation) by one or more processors of network node 110 and / or UE 120, may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 6 The process of 600 Figure 7 The process 700 and / or operations of other processes described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0054] In some aspects, the UE includes: a means for receiving an NCD-SSB configuration indicating one or more parameters for transmission via at least one NCD-SSB burst corresponding to at least one NCD-SSB set associated with at least one cell, the at least one cell including at least one of a primary cell or a secondary cell; and / or a means for receiving the at least one NCD-SSB burst based at least in part on the NCD-SSB configuration. The means for the UE to perform the operations described herein may include, for example, one or more of the following: the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0055] In some aspects, the network node includes: a means for transmitting an NCD-SSB configuration indicating one or more NCD-SSB parameters corresponding to transmission of at least one NCD-SSB associated with at least one cell, the at least one cell including at least one of a primary cell or a secondary cell; and / or a means for transmitting the at least one NCD-SSB to the UE based at least in part on the NCD-SSB configuration. In some aspects, the means for the network node to perform operations described herein may include, for example, one or more of the communication manager 150, the transmit processor 220, the TX MIMO processor 230, the modem 232, the antenna 234, the MIMO detector 236, the receive processor 238, the controller / processor 240, the memory 242, or the scheduler 246.

[0056] Although Figure 2 The blocks in the 2000 and 2010 are illustrated as distinct components, but the functionality described above with respect to these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described with respect to the transmit processor 264, the receive processor 258, and / or the TX MIMO processor 266 may be performed by or under the control of the controller / processor 280.

[0057] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 Different from what is described.

[0058] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. "Network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0059] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack physically or logically integrated within a single RAN node (e.g., within a single device or unit). A decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack physically or logically distributed between two or more units (such as one or more CUs, one or more DUs, or one or more RUs). In some examples, a CU may be implemented within a network 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 network 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, such as a virtual central unit (VCU), a virtual distributed unit (VDU), or a virtual radio unit (VRU), and the like.

[0060] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.

[0061] Figure 3 3 is a diagram illustrating an example decomposed base station architecture 300 according to the present disclosure. The decomposed base station architecture 300 may include a CU 310, which may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more decomposed control units (such as a near-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 CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.

[0062] Each of the units (including CU 310, DU 330, RU 340) and the near-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 referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of the units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or transmit signals to one or more of the other units via a wired transmission medium, and the wireless interface being configured to receive signals or transmit signals to one or more of the other units via a wireless transmission medium, or both.

[0063] In some aspects, CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by CU 310. CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface (such as an E1 interface). As needed, CU310 may be implemented to communicate with DU 330 for network control and signaling.

[0064] Each DU 330 may correspond to a logical unit that includes 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 MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partition such as that defined by 3GPP. In some aspects, one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.

[0065] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions based on functional splits (e.g., functional splits defined by 3GPP) such as lower layer functional splits, or low PHY layer functions such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. In this architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of control plane and user plane communications with the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.

[0066] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may 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) platform 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, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN, such as an open eNB (O-eNB) 311, via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.

[0067] 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 updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.

[0068] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).

[0069] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 Different from what is described.

[0070] Figure 4 4 is a diagram illustrating an example 400 of a synchronization signal (SS) hierarchy according to the present disclosure. Figure 4 As shown in , the SS hierarchy may include an SS burst set 405, which may include multiple SS bursts 410 (shown as SS Burst 0 to SS Burst N-1, where N is the maximum number of repetitions of the SS burst 410 that can be sent by the base station). As further shown, each SS burst 410 may include one or more synchronization signals and physical broadcast channel blocks (SSBs) 415 (shown as SSB 0 to SSB M-1), where M is the maximum number of SSBs 415 that the SS burst 410 can carry. In some aspects, different SSBs 415 can be beamformed in different manners (e.g., transmitted using different beams) and can be used for cell search, cell acquisition, beam management, and / or beam selection (e.g., as part of an initial network access process). The SS burst set 405 may be sent by a wireless node (e.g., network node 110) periodically (such as every X milliseconds), as shown. Figure 4 In some aspects, SS burst set 405 can have a fixed or dynamic length (in Figure 4 In some cases, the SS burst set 405 or the SS burst 410 may be referred to as a discovery reference signal (DRS) transmission window or an SSB measurement time configuration (SMTC) window.

[0071] In some aspects, the SSB 415 may include resources that carry the PSS 420, SSS 425, and / or PBCH 430. In some aspects, multiple SSBs 415 are included in the SS burst 410 (e.g., utilizing transmissions on different beams), and the PSS 420, SSS 425, and / or PBCH 430 may be the same across each SSB 415 of the SS burst. In some aspects, a single SSB 415 may be included in the SS burst 410. In some aspects, the SSB 415 may be at least four symbols (e.g., OFDM symbols) in length, with each symbol carrying one or more of the following: the PSS 420 (e.g., occupying one symbol), the SSS 425 (e.g., occupying one symbol), and / or the PBCH 430 (e.g., occupying two symbols). In some aspects, the SSB 415 may be referred to as a SS / PBCH block.

[0072] In some aspects, the symbols of SSB 415 are consecutive, such as Figure 4 As shown. In some aspects, the symbols of the SSB 415 are non-contiguous. Similarly, in some aspects, one or more SSBs 415 of the SS burst 410 may be sent in contiguous radio resources (e.g., consecutive symbols) during one or more time slots. Additionally or alternatively, one or more SSBs 415 of the SS burst 410 may be sent in non-contiguous radio resources.

[0073] In some aspects, the SS burst 410 may have a burst periodicity, and the SSB 415 of the SS burst 410 may be sent by a wireless node (e.g., network node 110) according to the burst periodicity. In this case, the SSB 415 may repeat during each SS burst 410. In some aspects, the SS burst set 405 may have a burst set periodicity, whereby the SS bursts 410 in the SS burst set 405 are sent by the wireless node according to a fixed burst set periodicity. In other words, the SS burst 410 may repeat during each SS burst set 405.

[0074] In some aspects, the SSB 415 may include an SSB index, which may correspond to a beam for carrying the SSB 415. The UE 120 may monitor and / or measure the SSB 415 using different receive (Rx) beams during an initial network access procedure and / or a cell search procedure, among other examples. Based at least in part on the monitoring and / or measurement, the UE 120 may indicate one or more SSBs 415 having the best signal parameters (e.g., RSRP parameters) to the network node 110. The network node 110 and the UE 120 may use the indicated one or more SSBs 415 to select one or more beams to be used for communication between the network node 110 and the UE 120 (e.g., for a random access channel (RACH) procedure). Additionally or alternatively, the UE 120 may use the SSB 415 and / or the SSB index to determine a cell timing for a cell (e.g., a serving cell) via which the SSB 415 is received.

[0075] In some aspects, a network node may serve different UEs of different categories and / or support different UEs of different capabilities. For example, a network node may serve a first category of UEs with less advanced capabilities (e.g., lower capabilities and / or reduced capabilities) and a second category of UEs with higher 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 be referred to as reduced capability (RedCap) UEs (which may be interchangeably referred to as reduced capability UEs, also with the acronym "RedCap"), low-end UEs, and / or NR light UEs, etc. The second category of UEs may be ultra-reliable low-latency communications (URLLC) devices and / or enhanced mobile broadband (eMBB) devices and may have an advanced feature set compared to RedCap UEs. RedCap UEs may include wearable devices, IoT devices, sensors, cameras, etc. associated with limited bandwidth, power capacity, and / or transmission range, etc. The second category of UEs may be referred to as baseline UEs, high-end UEs, NR UEs, and / or advanced UEs, etc. In some aspects, a RedCap UE may have capabilities that meet requirements of a first wireless communication standard but not a second wireless communication standard, while a second category of UEs may have capabilities that meet requirements of the second wireless communication standard (and in some cases, the first wireless communication standard as well).

[0076] For example, the first category of RedCap UEs may support a lower maximum MCS than the second category of UEs (e.g., supporting quadrature phase shift keying (QPSK) compared to 256-quadrature amplitude modulation (QAM), etc.), may support a lower maximum transmit power than the second category of UEs, may have less advanced beamforming capabilities than the second category of UEs (e.g., may not be able to form as many beams as the second category of UEs), may require longer processing time than the second category of UEs, may include less hardware than the second category of UEs (e.g., fewer antennas, fewer transmit antennas, and / or fewer receive antennas), and / or may not be able to communicate over a maximum bandwidth part (BWP) as wide as the second category of UEs, etc. In some instances, the bandwidth, power capacity, computing power, and / or transmit range of the RedCap UEs may be limited or reduced relative to eMBB UEs (which may be interchangeably referred to herein as "non-RedCap eMBB UEs"). Similarly, a BWP, control channel, search space set and / or bandwidth or other features that are dedicated to or otherwise specifically intended for use with or by a RedCap UE may be referred to as "RedCap dedicated." A BWP, control channel, search space set and / or bandwidth or other features that are dedicated to or otherwise specifically intended for use with or by a non-RedCap UE and / or are not RedCap dedicated may be referred to as "non-RedCap dedicated."

[0077] For the FR1 time division duplex (TDD) band where the center bandwidth (CBW) is ≥ 50 MHz, the overhead of sending the NCD-SSB set may be less than 1% (of the total SSB set sent) for a typical TDD slot format with 20 milliseconds (ms) SSB periodicity and 4 or 8 beams per SSB burst. The serving cell of a RedCap UE may send a cell definition (CD) SSB (CD-SSB) set and an NCD-SSB set with the same physical cell identifier (PCI). The NCD-SSB set may be quasi co-located ("QCL") with the CD-SSB set with the same SSB index. The SSB set (CD or NCD) may be sent in an RRC configured DL BWP for a RedCap UE that does not support unrestricted DL BWP. In some cases, a RedCap UE using an NCD-SSB set may support mandatory eMBB UE features based on CD-SSB sets.

[0078] In some cases, a TDD configuration (e.g., tdd-UL-DL-ConfigurationCommon) may provide a single slot mode (e.g., mode 1) in which the period is Pms, or two different slot modes (e.g., mode 1 and mode 2) in which the effective period is P+P2ms. 20ms is divided using applicable values ​​of P and (P+P2). Therefore, when a single slot configuration mode 1 is configured and P=10, the time offset of 5*(2k+1)ms imposes additional constraints on the slot mode of the second half frame (e.g., the slots and / or symbols occupied by the SSB set may be configured as downlink ("D"), although in theory the slots and / or symbols may also be configured as uplink ("U") or flexible ("F")). When two different slot modes are configured and P=P2=5, the time offset of 5*(2k+1)ms imposes additional constraints on "U" and "F" on mode 2. Similarly, when two different time slot modes are configured and P=P2=10, a time offset of 5*(2k+1) or 10*(2k+1) ms imposes additional constraints on “U” and “F” on Mode 1 and / or Mode 2.

[0079] In a cell to which RedCap UEs are allowed access, an NCD-SSB set may be sent at least in the RRC-configured DL BWP of the RedCap UE. The RedCap UE may use NCD-SSB (including measurements based on NCD-SSB) as a mandatory feature in an RRC-configured DL BWP that does not include a CD-SSB set to support existing applicable mandatory features based on SSB sets. In this case, the NCD-SSB shares the same PCI as the CD-SSB set, the NCD-SSB has the same set of parameters as the CD-SSB set, and the NCD-SSB is "QCL" with the CD-SSB set when the NCD-SSB and the CD-SSB set share the same SSB index. The periodicity of the NCD-SSB is not less than the periodicity of the CD-SSB set, which may be selected from the range {5, 10, 20, 40, 80, 160} ms. However, in some cases, NCD-SSBs of associated NCD-SSB sets independent of the RedCap UE context are not supported.

[0080] Some aspects of the techniques and apparatus described herein may provide for extending the use of NCD-SSB to non-RedCap UEs and / or to NCD-SSB configurations in which the context of the accompanying CD-SSB set is also not utilized. For example, in some aspects, in order to facilitate scheduling flexibility of the network, a non-zero time offset between the NCD-SSB and the CD-SSB may be configured. In some aspects, other NCD-SSB parameters may be configured to facilitate the use of NCD-SSB by RedCap and non-RedCap UEs. In some aspects, for example, a UE may receive an NCD-SSB configuration indicating one or more parameters transmitted via at least one NCD-SSB burst corresponding to at least one NCD-SSB set associated with at least one cell. The at least one cell may be at least one of a primary cell or a secondary cell. The UE may receive at least one NCD-SSB burst based at least in part on the NCD-SSB configuration. In this way, for example, the NCD-SSB configuration may be extended to allow for a reduction in the signaling overhead of periodic reference signals for synchronization, automatic gain control, beam management, radio link monitoring, and / or beam failure recovery. The extension of NCD-SSB may also support the coexistence of different types of UEs and multiple timing advance groups (TAGs). In some aspects, the extension of NCD-SSB may also help accommodate different slot mode configurations for TDD without affecting UL coverage and / or throughput. Thus, some aspects may positively impact network performance.

[0081] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 Different from what is described.

[0082] Figure 5 is a diagram illustrating an example 500 associated with an NCD-SSB configuration according to the present disclosure. Figure 5 As shown, UE 502 and network node 504 can communicate with each other. Network node 504 can be one or more TRPs, can include the one or more TRPs, or can be included in the one or more TRPs, and can support one or more cells, including one or more serving cells and / or one or more secondary cells. In some aspects, UE 502 can be a RedCap UE, and in some other aspects, UE 502 can be a non-RedCap UE.

[0083] As shown by reference numeral 506, the network node 504 may send and the UE 502 may receive an NCD-SSB configuration. The NCD-SSB configuration may indicate one or more parameters corresponding to at least one NCD-SSB set associated with at least one cell transmitted via at least one NCD-SSB burst. The at least one cell may include at least one of a primary cell or a secondary cell. In some aspects, the NCD-SSB configuration may be sent via at least one of system information (SI), an RRC message, a medium access control (MAC) control element (MAC CE), or downlink control information (DCI). As shown by reference numeral 508, the network node 504 may send at least one NCD-SSB burst based at least in part on the NCD-SSB configuration, and the UE 502 may receive at least one NCD-SSB burst based at least in part on the NCD-SSB configuration.

[0084] In some aspects, at least one NCD-SSB set is not transmitted with a cell-defined SSB set on at least one cell or a cell group associated with at least one cell. In some aspects, the NCD-SSB configuration may correspond to at least one of an NR TDD band, a sub-band full-duplex band (SBFD), a sub-band half-duplex band (SBHD), or an NR frequency division duplex (FDD) band. In some aspects, the NCD-SSB configuration may correspond to a dynamic spectrum sharing (DSS) carrier that supports multiple radio access technologies on a frequency band. For example, the NCD-SSB configuration may configure the UE 502 so that in the NR TDD and / or FDD bands and the DSS carrier, NCD-SSB bursts may be transmitted on a PCell, SCell, or both a PCell and a SCell with or without CD-SSB.

[0085] In some aspects, at least one cell may be associated with at least one TAG. At least one NCD-SSB set may be configured as a timing reference corresponding to a primary TAG of at least one TAG or a secondary TAG of at least one TAG. For example, for a cell supporting multiple TAGs, the NCD-SSB may be configured as a timing reference for a primary TAG (pTAG) and / or a secondary TAG (sTAG). In some aspects, NCD-SSB sets and NCD-SSB sets may be sent on cells that allow access to different UE types (e.g., RedCap and non-RedCap). For example, at least one NCD-SSB set may correspond to a downlink BWP. The downlink BWP may include at least one of an active downlink BWP or a default downlink BWP.

[0086] In some aspects, the downlink BWP may be configured with a periodic reference signal corresponding to at least one of synchronization, automatic gain control, beam management, radio link monitoring, or beam failure recovery. In some aspects, the periodic reference signal may include at least one of a tracking reference signal (TRS), a phase tracking reference signal (PTRS), or a non-zero power (NZP) channel state information reference signal (CSI-RS). In some aspects, at least one parameter corresponding to the reference signal may be based at least in part on the NCD-SSB configuration. For example, the at least one parameter may be at least one of the following: periodicity of an NCD-SSB set, a subcarrier spacing associated with an NCD-SSB set, a bitmap of transmitted NCD-SSB indexes per NCD-SSB burst, a time offset between a cell-defined SSB and an NCD-SSB set, a timer for BWP switching associated with NCD-SSB transmission within a bandwidth part (BWP), a time offset for BWP switching associated with NCD-SSB transmission within a BWP, a discontinuous reception (DRX) configuration associated with an NCD-SSB set, a wake-up signal (WUS) reception associated with an NCD-SSB set, a timer for BWP switching associated with NCD-SSB transmission within a BWP, a timer for BWP switching associated with NCD-SSB transmission within a BWP, a timer for BWP switching associated with NCD-SSB transmission within a BWP, a timer for BWP switching associated with BWP switching ...

[0087] In some aspects, the configuration and / or presence of the NCD-SSB may be provided via one or a combination of SI, RRC, MAC CE, and DCI. In some aspects, the NCD-SSB configuration indicates an energy per resource element (EPRE) or an EPRE ratio associated with at least one of the PSS or SSS. The NCD-SSB configuration may indicate at least one NCD-SSB parameter corresponding to the EPRE or the EPRE ratio. The at least one NCD-SSB parameter may include at least one of the following: a periodicity of an NCD-SSB set, a subcarrier spacing associated with an NCD-SSB set, a bitmap of transmitted NCD-SSB indices per NCD-SSB burst, a time offset between a cell-defined SSB and an NCD-SSB set, a timer for a BWP switching associated with an NCD-SSB transmission within a BWP, a time offset for a BWP switching associated with an NCD-SSB transmission within a BWP, a DRX configuration associated with an NCD-SSB set, a WUS reception associated with an NCD-SSB set, a timer ... timer for a BWP switching associated with an NCD-SSB transmission within a BWP, a timer for a BWP switching associated with an NCD-SSB transmission within a BWP, a DRX configuration associated with an NCD-SSB set, a WUS reception associated with an NCD-SSB set, a timer for a BWP switching associated with an NCD-SSB set, a timer for a BWP switching associated with an NCD-SSB set, a timer for a BWP switching associated with an NCD-SSB set, a timer for a BWP switching associated with an NCD-SSB set, a timer for a BWP switching associated with an NCD-SSB set, a timer for a BWP PEI signal reception associated with an SSB set, PDCCH monitoring reduction associated with an NCD-SSB set, PDCCH skip configuration associated with an NCD-SSB set, conflict handling process between uplink transmission and reception of an NCD-SSB set, timing advance verification process associated with an NCD-SSB set, power control process associated with an NCD-SSB set, timing control process associated with an NCD-SSB set, verification process of uplink channels and reference signals associated with an NCD-SSB set, measurement object configuration of an NCD-SSB set, or frequency range of a cell. For example, an NCD-SSB burst may include up to 64 SSB indexes. However, not all 64 SSB indexes need to be sent on one cell. Instead, the network node 504 may signal a bitmap to the UE 502 to indicate which SSB indexes are actually sent in the NCD-SSB burst.

[0088] At least one NCD-SSB set may include multiple SSB indexes, and the UE may receive at least one NCD-SSB set based on receiving multiple SSB indexes within a half frame of a radio frame. For example, in some aspects, all SSB block indexes of an NCD-SSB burst may be sent within a half frame of a radio frame. In some aspects, as shown by reference numeral 510, the network node 504 may send and the UE 502 may receive a reference CD-SSB set associated with at least one cell or at least one of a cell group corresponding to at least one cell. At least one cell may be configured with an NCD-SSB set, and at least one NCD-SSB set may be mapped to a first half frame of a first radio frame. The CD-SSB set may be mapped to a second half frame of a second radio frame. In some aspects, the first half frame may be a second half frame. For example, when an NCD-SSB and a reference CD-SSB set are sent on the same cell or cell group, the NCD-SSB set and the CD-SSB set may be mapped to the same half frame or different half frames of a radio frame. In some aspects, a half frame may be a 5ms time period and a radio frame may be a 10ms time period.

[0089] In some aspects, at least one NCD-SSB may include multiple NCD-SSB bursts, and the CD-SSB set may include multiple CD-SSB bursts having a first CD-SSB burst associated with a reference system frame number (SFN) (e.g., SFN#0). The NCD-SSB configuration may indicate a time offset between a first symbol of a first NCD-SSB burst sent on or after the reference system frame number and a first symbol of a first CD-SSB burst associated with the reference system frame number. In some aspects, the time offset may include a number of time slots equal to the product of a constant time unit and a variable having a value equal to a selected integer. The selected integer may include an integer selected from a subset of a specified integer range including negative values, positive values, and zero. For example, the time duration of O time slots may be equal to 5*kms, where k is an integer in the range [-32,32]. Examples of constant time units may include 5ms, 1ms, and / or 10ms, among other examples.

[0090] In some aspects, the time slot duration corresponding to the constant time unit may be based at least in part on at least one of the reference parameter sets associated with the CD-SSB set or the at least one NCD-SSB set transmitted on at least one cell or the same cell group. In some aspects, at least one NCD-SSB may correspond to an FDD band, an SBFD, or a sub-band half-duplex band, and the subset of the specified integer range may include a specified integer range. For example, on the FDD band, k may be any value within the range [-32,32]. In some aspects, at least one NCD-SSB may correspond to a TDD band, and the subset of the specified integer range may be based at least in part on the TDD slot mode configuration and the mapping from multiple NCD-SSB indexes associated with the NCD-SSB burst in multiple NCD-SSB bursts to one or more downlink time resources corresponding to the TDD slot mode. On the TDD band, k may be selected to ensure that all NCD-SSB blocks indicated by ssb-PositionsInBurst are mapped to the DL slots / symbols of the TDD slots.

[0091] In some aspects, at least one NCD-SSB may correspond to a dynamic spectrum sharing carrier, and the subset of the specified integer range may be based at least in part on at least one of: a first mapping between multiple NCD-SSBs associated with an NCD-SSB burst in a plurality of NCD-SSB bursts and one or more multicast-broadcast single frequency network (MBSFN) subframes or a second mapping between the multiple NCD-SSBs and one or more downlink symbols not associated with the CRS.

[0092] In some aspects, the UE 502 may receive system information, and at least one NCD-SSB may correspond to a TDD band, a sub-band full duplex band (SBFD), or a sub-band half duplex band (SBHD). The subset of the specified integer range may be based at least in part on one or more mode configurations. The one or more mode configurations may include at least one of a TDD time slot mode, a SBFD mode, or a SBHD mode. The one or more mode configurations may be indicated by at least one of the system information, a medium access control layer control element (MAC CE), a dynamic time slot format indication, or an RRC message. In some aspects, the one or more mode configurations may include a single time slot mode configuration indicating a single time slot mode with downlink resources suitable for SSB burst transmission. The subset of the specified integer range may be based at least in part on a periodic pattern of a single time slot mode. In some aspects, one or more TDD time slot mode configurations may indicate two time slot modes having downlink resources suitable for SSB burst transmissions, and the subset of the specified integer range may be based at least in part on a sum of a first periodicity pattern of a first time slot mode of the two time slot modes and a second periodicity pattern of a second time slot mode of the two time slot modes.

[0093] In some aspects, at least one of the first half-frame or the second half-frame may correspond to a first mapping between a first plurality of SSB indices associated with at least one NCD-SSB burst and a first set of downlink resources or a second mapping between a second plurality of SSB indices associated with a CD-SSB burst and a second set of downlink resources. The time offset may include an integer number of half-frames indicated by at least one of an SI, an RRC message, a MAC CE, or a DCI.

[0094] For example, in the first option, the time duration of O slots may be equal to 5*kms, where k is an integer in the range [-32,32]. On the FDD band, k may be any value in the range [-32,32]. On the TDD band, the selection of k may be performed to ensure that all NCD-SSB blocks indicated by ssb-PositionsInBurst are mapped to DL slots / symbols of TDD slots. On the DSS carrier, the selection of k may be performed to ensure that all NCD-SSB blocks indicated by ssb-PositionsInBurst are mapped to MBSFN subframes or DL ​​symbols without LTE-CRS.

[0095] In the second option, on the TDD band, O may depend on the slot mode configuration provided in the SI. For example, if only a single TDD slot mode (pattern1) is provided by tdd-UL-DL-ConfigurationCommon, the periodicity (P) of pattern1 is divided into time offset O. If two different slot modes are provided by tdd-UL-DL-ConfigurationCommon, the effective periodicity (P+P2) of the two TDD slot modes is divided into time offset O. In the third option, within a half frame containing an NCD-SSB burst or a CD-SSB burst, the SSB block index may be mapped to the same or different DL slot / symbol sets, where the time offset O is an integer provided by SI, RRC, MAC CE or DCI.
