[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. patent application No. 17 / 811,839, filed on July 11, 2022, entitled “SKIPPED PORTIONS OF SYNCHRONIZATION SIGNAL BLOCKS ASSOCIATED WITH BEAMS HAVING AN ESTABLISHED CONNECTION,” which is hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications and to techniques and apparatus for skipping portions of synchronization signal blocks (SSBs) associated with beams with established connections. 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, etc.).

[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 better integrate with other open standards by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and 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. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] 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. On the contrary, these aspects are provided so that the present disclosure will be thorough and complete, and the 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 present 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.

It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

[0031] 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.

[0032] 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).

[0033] 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 elements of a 4G (e.g., Long Term Evolution (LTE)) network, as well as other examples. 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)).

[0034] In some examples, the network node 110 is or includes a network node that communicates with the UE 120 via a radio access link, such as an RU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a fronthaul link or a midhaul link, such as a DU. In some examples, the network node 110 is or includes a network node that communicates with other network nodes 110 via a midhaul link or communicates with the core network via a backhaul link, such as a CU. 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.

[0035] 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 in , 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).

[0036] 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 the 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. Thus, a single device may include more than one base station.

[0037] 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 is capable of relaying transmissions for other UEs 120. Figure 1 In the example shown in , 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 communications 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.

[0038] 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).

[0039] The network controller 130 may be coupled to or in communication with a set 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 backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.

[0040] 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 computer, 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.

[0041] 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 that 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 in 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.

[0042] 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, an air interface, etc. Frequency may be referred to as a carrier, a 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.

[0043] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly (e.g., without using network node 110 as an intermediary to communicate with each other) using one or more side link channels. 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.

[0044] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., based on 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. Similar naming issues sometimes occur with respect to FR2, which is often (interchangeably) referred to as the “millimeter wave” band in documents and articles, although different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the “millimeter wave” band by the International Telecommunication Union (ITU).

[0045] 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, higher frequency bands are currently 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.

[0046] 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.

[0047] In some aspects, UE 120 may include a communication manager 140. As described in greater detail elsewhere herein, the communication manager 140 may establish a connection with a network node using a beam; and receive an indication that the network node will avoid transmission of a synchronization signal block (SSB) signaling during a portion of an SSB opportunity associated with the beam based at least in part on establishing the connection using the beam. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0048] In some aspects, the network node may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may establish a connection with the UE using a beam; and send an indication that the network node will avoid sending SSB signaling during a portion of an SSB opportunity associated with the beam based at least in part on establishing the connection using the beam. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0049] As indicated above, Figure 1are provided as examples. Other examples can be found in the Figure 1 The examples described are different.

[0050] 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.

[0051] 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 partitioning 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 modulators) (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 further 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).

[0052] 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 a housing.

[0053] 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.

[0054] 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 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.

[0055] 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 6 to 11 ) any aspects of any of the methods described herein.

[0056] 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 execute the instructions described herein (e.g., reference 20). Figures 6 to 11 ) any aspects of any of the methods described herein.

[0057] 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 controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or the like may perform one or more techniques associated with skipping a portion of an SSB associated with a beam having an established connection, 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 8 The process of 800 Fig. 9 900 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 by one or more processors of network node 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 8 The process of 800 Fig. 9 The process 900 of , and / or the operation of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.

[0058] In some aspects, the UE includes: means for establishing a connection with a network node using a beam; and / or means for receiving an indication that the network node will avoid transmission of SSB signaling during a portion of an SSB opportunity associated with the beam based at least in part on establishing the connection using the beam. Means for the UE to perform operations described herein may include, for example, one or more of the following: a communication manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0059] In some aspects, the network node includes: means for establishing a connection with the UE using a beam; and / or means for transmitting an indication that the network node will avoid transmission of SSB signaling during a portion of an SSB opportunity associated with the beam based at least in part on establishing the connection using the beam. In some aspects, 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.

[0060] Although Figure 2 The blocks in the 200 and 210 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.

[0061] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.

[0062] 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).

[0063] 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 a CU, a DU, and a 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.

[0064] 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. Various 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.

[0065] 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. The DU 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 by multiple RUs 340 simultaneously.

[0066] 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, the one or more interfaces being configured to receive or send 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 send signals to one or more of the other units via a wired transmission medium, the wireless interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, or both.

[0067] 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, CU 310 may be implemented to communicate with DU 330 for network control and signaling.

[0068] 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) coding 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.

[0069] 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 or low PHY layer functions based on functional split (e.g., functional split defined by 3GPP) (such as lower layer functional split), 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.

[0070] The SMO framework 305 may be configured to support RAN deployment and configuration 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 335) 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.

[0071] 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.

[0072] 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 regulate 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 measures 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).

[0073] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.

[0074] 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, the SS hierarchy may include an SS burst set 405, which may include multiple SS bursts 410 (shown as SS Burst 0 through SS Burst N-1, where N is the maximum number of repetitions of the SS burst 410 that may be sent by one or more network nodes). As further shown, each SS burst 410 may include one or more SSBs 415 (shown as SSB 0 through SSB M-1, where M is the maximum number of SSBs 415 that may be carried by the SS burst 410). In some aspects, different SSBs 415 may be beamformed in different manners (e.g., transmitted using different beams) and may be used for cell search, cell acquisition, beam management, and / or beam selection (e.g., as part of an initial network access procedure). The SS burst set 405 may be sent periodically (such as every X milliseconds) by a wireless node (e.g., network node 110), such as 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 SS burst 410 may be referred to as a discovery reference signal (DRS) transmission window or an SSB measurement time configuration (SMTC) window.

[0075] In some aspects, the SSB 415 may include resources that carry the PSS 420, the SSS 425, and / or the physical broadcast channel (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 410. 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 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 an SS / PBCH block.

[0076] In some aspects, the symbols of SSB 415 are consecutive, such as Figure 4 . 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.

[0077] 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.

[0078] 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 (e.g., directly or via one or more other network nodes). 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 of a cell (e.g., a serving cell) via which the SSB 415 is received.

[0079] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.

[0080] Figure 5 is a diagram illustrating an example 500 of an SSB burst including transmitting SSB signaling on multiple beams according to the present disclosure. Figure 5 In the context of, a network node (e.g., a CU, DU, and / or RU) may send an SSB within a cell associated with and / or provided by the network node.

[0081] like Figure 5 As shown, the set of SSBs 505A may include SSBs 510A-510H (in Figure 5 As shown in the figure as including PSS, PBCH, SSS and PBCH). In some networks, the number of SSBs (SSB signaling) within an SSB burst may include any number of SSBs, such as 8, 16, 32, 64, 128 (not limited to 2^n). Each of the SSBs may be associated with a different beam. For example, the network node may send a first SSB 510A in a direction associated with beam 0, a second SSB 510B in a direction associated with beam 1, and so on. The network node may send the SSBs via associated beams in a beam scanning process in which the network node sends the SSBs sequentially. In this way, the network node may sweep and / or cover a cell range (e.g., and the entire cell range in the spatial dimension). Multiple SSBs sent on different half-slots during an SSB opportunity may be limited to a predefined time window duration (e.g., a 5 millisecond (ms) window), and the multiple SSBs form an SSB burst as described herein.

[0082] In some networks, SSB 505 may be periodic. For example, the network node may send a set of SSBs 505A at a first SSB opportunity, a set of SSBs 505B at a second SSB opportunity, and a set of SSBs 505C at a third SSB opportunity. In this way, a UE in a cell provided by the network node may periodically measure the SSB and / or the associated signal strength on the beam used to transmit the SSB.

[0083] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.

[0084] A UE within the coverage of a cell may use SSB for several purposes. For example, the UE may measure SSB to discover a cell and connect to the cell (e.g., an initial acquisition (Init Ack) process). Additionally or alternatively, the UE may use SSB to maintain continuous time and frequency synchronization with a network (e.g., a network including the cell), a serving beam, and / or automatic gain control (AGC) tracking (e.g., in connected mode). In some networks, the UE may use SSB to maintain serving cell and neighbor cell measurements to support mobility and handover procedures between cells.

[0085] In some networks (e.g., sub-terahertz networks), it is desirable to use narrow beams to compensate for the increase in path loss and the decrease in power amplifier output power (e.g., due to the increase in the carrier frequency of transmission). For example, a half-power beamwidth of 2 degrees can be used to achieve a 40 decibel gain (dBi) via directivity. The dBi can support gains in throughput and coverage of the cell. It is desirable that a uniform rectangular array (e.g., a rectangular configuration of antenna elements) be implemented using similar beams with similar dBi.

[0086] Communications between network nodes and UEs in the sub-THz band are expected to operate well over relatively short distances compared to communications using lower frequency bands (e.g., FR1 or FR2). The combination of short link communications and very narrow beams results in "per-UE communication beams," where each beam serves at most one UE. However, sending SSBs on a beam to which a UE is already connected may unnecessarily consume power, network, communication, and processing resources because, for example, additional UEs are unlikely to be in the beam path of the beam, based at least in part on the UE already being connected via the beam.

[0087] In some aspects described herein, a network node may puncture an SSB opportunity by refraining from transmitting SSB signaling during a portion of an SSB opportunity associated with a beam to which a UE is connected. In some aspects, a network node may increase throughput based at least in part on weakening SSB transmissions of a beam with a connected UE and instead transmitting other channels such as a tracking reference signal (TRS), a channel state information reference signal (CSI-RS), and / or data signaling such as a physical downlink shared channel (PDSCH), and the like.

[0088] Based at least in part on avoiding sending SSB signaling during a portion of an SSB opportunity associated with a beam to which a UE is already connected, a network node may save power, network, communication, and processing resources that might otherwise have been used to send SSBs on beams that already have connected UEs. Additionally or alternatively, based at least in part on sending other signaling in place of SSB signaling, a network node may increase throughput and reduce overhead. Additionally or alternatively, a network node may send SSBs only for beams to which a UE is not connected, which may reduce the number of SSBs to be sent in an SSB burst. In networks with a relatively high number of beams (e.g., sub-THz networks), sending SSBs for all beams during each SSB opportunity may be prohibited by available time windows, or time windows that may require reducing resources for sending data or other signaling.

[0089] In some aspects, a UE may send (e.g., at connection establishment) an indication that the UE supports truncating SSBs. The support may be based at least in part on and the indication may indicate the ability to maintain (e.g., keep) a tracking loop on a non-SSB channel such as TRS, CSI-RS, and / or DMRS on PDSCH (e.g., the periodicity of PDSCH DMRS replacing SSBs). The support may be based at least in part on and the indication may indicate the ability to estimate RSSI and / or RSRP on a non-SSB channel (e.g., based at least in part on multiple channels such as SSB and TRS, CSI-RS, and / or DMRS using threshold reliability for estimation). The support may be based at least in part on and the indication may indicate the TRS and / or CSI-RS periodicity used to supplement or replace SSB signaling (e.g., for maintaining a tracking loop). In some aspects, the indication of support may be based at least in part on channel conditions and / or signal to interference plus noise ratio (SINR) of the communication between the network node and the UE.

[0090] After establishing a connection, the network node may indicate to the UE that SSB truncation is activated and that the serving beam associated with the UE will not send SSB signaling on the SSB burst. For example, the network node may indicate that the network node will not send SSB signaling during one or more SSB opportunities and / or may indicate that the network node will send SSB with a reduced periodicity and / or duty cycle (impaired SSB). When using impaired SSB, the network node may indicate an SSB periodicity to the UE to indicate the periodicity of the SSB opportunities at which the network node will send SSB signaling on the serving beam.

[0091] The UE may maintain a tracking loop based at least in part on one or more non-SSB channels such as TRS, CSI-RS, and / or PDSCH DMRS.In some aspects, the UE may maintain a tracking loop based at least in part on SSBs with reduced periodicity.

[0092] To improve the estimator and based on channel conditions and / or SINR, the UE may trigger and / or request resources (e.g., channels) to replace SSB signaling (e.g., SSB channels and / or SSB periodicity). In some aspects, the resources used to replace SSB signaling may be allocated differently to optimize the UE estimator and / or throughput (e.g., based at least in part on changes in SINR).

[0093] If a handover procedure is required, the network node may indicate that SSB signaling on the serving beam is enabled before completing the handover. In this way, SSB signaling on the serving beam may be resumed to allow additional UEs to connect via the serving beam and / or allow the UE to make measurements to determine whether a handover back to the serving beam is required.

[0094] The network node may indicate to the UE that one or more additional beams are not active and / or the network node will avoid sending SSBs via the one or more additional beams. For example, the network node may send indices of the one or more additional beams to avoid compromising and / or disrupting a beam search or cell search algorithm. In some aspects, the network node may send additional signaling to the UE during a portion of an SSB opportunity associated with the one or more additional beams. In some aspects, the network node may skip one or more additional beams.

[0095] In some aspects, a network node may send an indication of inactive SSBs on a cell associated with the network node and / or on one or more neighboring cells (in an RRC message or in a medium access control (MAC) control element (CE)). In some aspects, a network node may send an indication of inactive SSBs via RRC signaling, MAC CE, and / or system information block (SIB), etc. In some aspects, a network node may be configured to have a threshold number of SSBs that may be inactive within a cell (e.g., per cell identity).

[0096] Figure 6 6 is a diagram of an example 600 associated with a skipped portion of an SSB associated with a beam having an established connection according to the present disclosure. Figure 6 As shown, a network node (e.g., network node 110, CU, DU, and / or RU) may communicate with a UE (e.g., UE 120). In some aspects, the network node and the UE may be part of a wireless network (e.g., wireless network 100). The UE and the network node may be in a Figure 6 The operations shown are performed after a wireless connection has been established.

[0097] As indicated by reference numeral 605, the network node may send configuration information, and the UE may receive the configuration information. In some aspects, the UE may receive the configuration information via one or more of RRC signaling, one or more MAC CEs, and / or downlink control information (DCI), etc. In some aspects, the configuration information may include an indication of one or more configuration parameters for the UE to select (e.g., known to the UE and / or previously indicated by the network node or other network device) and / or explicit configuration information for the UE to configure the UE, etc.

[0098] In some aspects, the configuration information may indicate that the UE will send an indication of support for skipping SSB signaling during an SSB opportunity. In some aspects, the configuration information may indicate that the UE will receive an indication of a type of additional signaling in place of the SSB signaling skipped during the SSB opportunity. In some aspects, the configuration information may indicate that the UE will send a request for resources to replace the SSB (e.g., for maintaining a tracking loop).

[0099] The UE may configure itself based at least in part on the configuration information.In some aspects, the UE may be configured to perform one or more operations described herein based at least in part on the configuration information.

[0100] As shown by reference numeral 610, the UE may send, and the network node may receive, an indication of support for skipping SSB signaling (e.g., via a capability report). For example, the UE may send an indication of support for skipping SSB signaling associated with a beam through which the UE is already connected to the network node. In some aspects, the UE may send an indication of support for skipping SSB signaling associated with one or more additional beams to which the UE is not connected.

[0101] In some aspects, the indication of support for skipping SSB signaling may indicate whether the UE supports maintaining a tracking loop without SSB signaling, the type of resources required for the UE to maintain a tracking loop without SSB signaling (e.g., on non-SSB channels and / or resources), whether the UE supports receiving other signaling in place of SSB signaling, and / or whether the UE supports receiving additional signaling in place of additional SSB signaling associated with a different beam (e.g., a non-serving beam for the UE). For example, the UE may send an indication that the UE supports sending an indication of the ability to maintain a tracking loop on a non-SSB channel, sending an indication of the ability to estimate signal strength on a non-SSB channel, and / or sending an indication of a requested periodicity of a non-SSB reference signal for maintaining a tracking loop, etc.

[0102] As shown in reference numeral 615, the UE and the network node may establish a connection using a beam (network node beam). For example, the UE and the network node may establish a connection using a beam after a beam management procedure and / or a random access procedure, etc. In some aspects, a beam may only support a single UE. In some aspects, a beam may be associated with a relatively high carrier frequency (e.g., a sub-terahertz frequency).

[0103] As shown by reference numeral 620, the UE may receive and the network node may send an indication that the network node will avoid sending SSB signaling during a portion of an SSB opportunity associated with a beam. In some aspects, the network node may send the indication based at least in part on establishing a connection using the beam. The SSB opportunity may include multiple portions with SSB signaling associated with different beams that may be used to communicate with the network node.

[0104] In some aspects, the indication that the network node is to avoid transmission of SSB signaling includes an indication of the periodicity of SSB opportunities configured to carry SSB signaling during a portion associated with the beam. For example, the indication may include an indication that a pattern of SSB opportunities will include SSB signaling associated with the beam and an opposite pattern of SSB opportunities will not include SSB signaling associated with the beam.

[0105] As indicated by reference numeral 625, the UE may receive and the network node may send an indication that the network node will avoid sending first additional SSB signaling during a first additional portion of an SSB opportunity associated with the first additional beam. In some aspects, the network node may send the indication as part of an indication of inactive SSBs and / or inactive beams. The indication of inactive SSBs and / or inactive beams may be associated with a serving cell associated with the network node and / or for a neighboring cell. In some aspects, the indication of inactive SSBs and / or inactive beams may be associated with a threshold number of inactive SSBs and / or inactive beams. For example, the indication of inactive SSBs and / or inactive beams may have a maximum number of indicated inactive SSBs or beams.

[0106] In some aspects, the UE may use the indication to avoid attempting to receive the first additional SSB signaling during the first additional portion of the SSB opportunity. Additionally or alternatively, the UE may determine the order of the transmitted SSBs based at least in part on the indication that the network node will avoid transmitting the first additional SSB signaling during the first additional portion of the SSB opportunity. In some aspects, the network node may indicate that the network node will skip the first additional SSB signaling and / or send different SSB signaling (e.g., associated with a different beam) in place of the first additional SSB signaling. Alternatively, the network node may indicate that the network node will send signaling to the UE, such as data and / or reference signals during the portion of the SSB opportunity associated with the skipped SSB signaling.

[0107] As shown by reference numeral 630, the UE may send, and the network node may receive, a request for resources to replace SSB signaling. In some aspects, the UE may indicate one or more options for resources that the UE may use to replace SSB signaling to maintain a connection with the network node. For example, the UE may indicate that the UE may maintain a tracking loop with the network node based at least in part on resources received for tracking (e.g., TRS, CSI-RS, and / or DMRS within data, etc.).

[0108] As indicated by reference numeral 635, during a portion of an SSB opportunity associated with a beam, the UE may receive and the network node may transmit data, TRS, CSI-RS, and / or data including one or more RSs (eg, DMRS).

[0109] As shown in reference numeral 640, the UE may receive RS and / or data signals during the first additional portion of the SSB opportunity and / or receive second additional SSB signaling during the second additional portion of the SSB opportunity. For example, the UE may receive data with DMRS and / or other RS, CSI-RS, and / or TRS during the second additional portion of the SSB opportunity based at least in part on the network node skipping the transmission of additional SSB signaling associated with the non-serving beam. In this way, the network node and the UE may save resources that may have been used to carry data with DMRS and / or other RS, CSI-RS, and / or TRS, etc.

[0110] In some aspects, the UE may receive additional SSB signaling during the second additional portion of the SSB opportunity as part of beam management and / or to determine whether beam reselection is appropriate. For example, the UE may measure signal strength from one or more additional portions of the SSB opportunity to determine whether the non-serving beam has a higher signal strength than the serving beam.

[0111] As indicated by reference numeral 645, the UE may maintain a tracking loop. The tracking loop may be associated with maintaining synchronization with a network node. In some aspects, the UE may maintain a tracking loop (e.g., one or more tracking loops) based at least in part on SSB signaling and / or non-SSB reference signals (e.g., CSI-RS, DMRS of a PDSCH, and / or TRS, etc.) received in additional SSB opportunities (e.g., in a portion associated with a beam).

[0112] As shown by reference numeral 650, the UE may receive and the network node may send an indication to initiate a handover or beam reselection and / or an indication that the network node will send SSB signaling during a portion of a subsequent SSB opportunity. In this way, the beam may be available for additional UEs to measure and / or connect with the network node. Additionally or alternatively, the beam may be available for the UE to measure to determine whether cell reselection back to the beam is appropriate (e.g., based at least in part on the signal strength of the SSB measured via the beam).

[0113] Based at least in part on avoiding sending SSB signaling during a portion of an SSB opportunity associated with a beam to which a UE is already connected, a network node may save power, network, communication, and processing resources that might otherwise have been used to send SSBs on beams that already have connected UEs. Additionally or alternatively, based at least in part on sending other signaling in place of SSB signaling, a network node may increase throughput and reduce overhead. Additionally or alternatively, a network node may send SSBs only for beams to which a UE is not connected, which may reduce the number of SSBs to be sent in an SSB burst. In networks with a relatively high number of beams (e.g., sub-THz networks), sending SSBs for all beams during each SSB opportunity may be prohibited by available time windows, or time windows that may require reducing resources for sending data or other signaling.

[0114] As indicated above, Figure 6 are provided as examples. Other examples can be found in relation to Figure 6 The examples described are different.

[0115] Figure 7 is a diagram illustrating an example 700 of an SSB burst including transmitting SSB signaling on multiple beams according to the present disclosure. Figure 7 In the context of, a network node (e.g., a CU, DU, and / or RU) may send an SSB within a cell associated with and / or provided by the network node.

[0116] like Figure 7 As shown, the set of SSBs 705A may include SSBs 710A-710H (in Figure 7 As shown in the figure as including PSS, PBCH, SSS and PBCH). In some networks, the number of SSBs (SSB signaling) within an SSB burst may include any number of SSBs, such as 8, 16, 32, 64, 128 (not limited to 2^n). Each of the SSBs may be associated with a different beam. For example, the network node may send a first SSB 710A in a direction associated with beam 0, a second SSB 710B in a direction associated with beam 1, and so on. The network node may send the SSBs via associated beams in a beam scanning process in which the network node sends the SSBs sequentially. In this way, the network node may sweep and / or cover a cell range (e.g., and the entire cell range in the spatial dimension). Multiple SSBs sent on different half-slots during an SSB opportunity may be limited to a predefined time window duration (e.g., a 5 millisecond (ms) window), and the multiple SSBs form an SSB burst as described herein.

[0117] In some networks, the set 705 may be periodic. For example, the network node may send a set 705A of SSBs at a first SSB opportunity, a set 705B of SSBs at a second SSB opportunity, and a set 705C of SSBs at a third SSB opportunity. In this way, a UE in a cell provided by the network node may periodically measure the SSBs and / or associated signal strengths on beams used to transmit the SSBs.

[0118] like Figure 7 As shown, SSB 710F may be associated with beam 5 through which the UE has established a connection. In the set of SSBs 705A, the network node may skip SSB 710F and / or replace SSB 710F with data and / or additional RS 715. For example, the network node may replace SSB 710F with data having DMRS, CSI-RS, and / or TRS, which may be used to synchronize with the network node and / or maintain a tracking loop for subsequent communications.

[0119] In some aspects, the set 705B and / or the set 705C may also skip the SSB 710F based at least in part on the UE supporting maintaining a tracking loop without the SSB 710F (e.g., via alternative resources and / or based at least in part on the RS within the data and / or the additional RS 715). Alternatively, the network node may send the SSB 710F with a reduced periodicity (e.g., skipping the SSB 710F in one or more of the sets 705 of SSBs and sending the SSB 710F in one or more additional sets 705 of SSBs). As indicated above, Figure 7 are provided as examples. Other examples can be found in the Figure 7 The examples described are different.
