Background Art

[0003] Wireless communication systems are widely deployed to provide a variety of telecommunications services, including telephone communication, video, data, messaging, and broadcasting. Typical wireless communication systems can employ multiple access technologies that 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), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-Carrier Frequency Division Multiple Access (SC-FDMA), Time Division Synchronous Code Division Multiple Access (TD-SCDMA), and Long Term Evolution (LTE). LTE / LTE-Advanced is a set of extensions to the Universal Mobile Telecommunications System (UMTS) mobile standard, published by the Third Generation Partnership Project (3GPP®).

[0004] A wireless network may include one or more network nodes that support communication between wireless communication devices, such as one or more user equipment (UEs). UEs may communicate with network nodes via downlink and uplink communications. "Downlink" (or "DL") refers to the communication link from a network node to a UE, and "uplink" (or "UL") refers to the communication link from a UE to a network node. Some wireless networks may support device-to-device communication via local links (e.g., sidelink (SL), wireless local area network (WLAN) links, and / or wireless personal area network (WPAN) links, among other examples).

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

[Figure 10] This is a diagram of an exemplary device for wireless communication according to the present disclosure. [Modes for carrying out the invention]

[0016] To meet increasing traffic demands, various efforts have been made to improve spectral efficiency in wireless networks and thereby increase network capacity (for example, by using higher-order modulation, advanced multiple-input, multiple-output (MIMO) antenna technology, and / or multi-cell tuning techniques, among other examples). Another way to improve network capacity is to expand system bandwidth. However, there is a severe shortage of available spectrum in lower frequency bands that were previously licensed or otherwise allocated to mobile network operators. Therefore, various techniques have been developed to enable the operation of cellular radio access technologies (RATs) in unlicensed or other shared spectrum.

[0017] Generally, one challenge that arises when operating a cellular RAT in an unlicensed spectrum is the need to ensure fair coexistence with existing systems that may also be operating in the unlicensed spectrum. For example, prior to gaining access to an unlicensed channel and / or transmitting over it, a user equipment (UE) with packets to transmit may need to perform a listen-before-talk (LBT) procedure to compete for access to the unlicensed channel. The LBT procedure may include detecting the energy level on the unlicensed channel and determining whether the energy level satisfies a threshold (e.g., is below it), sometimes called an energy detection threshold. When the energy level satisfies the threshold (e.g., is below it), the UE may gain access to the unlicensed channel for a duration that may be called channel occupancy time (COT), during which the UE can transmit without performing any additional LBT operations.

[0018] For example, when communicating on a sidelink in an unlicensed spectrum, a transmitting (Tx) UE may transmit a sidelink synchronization signal block (S-SSB) transmission to convey configuration information to a receiving (Rx) UE. The Tx UE may repeat the S-SSB across multiple resource block (RB) sets, such as on an anchor RB set and a non-anchor RB set, to maintain a wideband coherent time (COT) over a set of S-SSB candidate slots. In this case, the Tx UE repeats the S-SSB waveform at all candidate S-SSB slots within the COT after clearing the listen-before-talk (LBT) procedure. The wideband COT may include a COT associated with a bandwidth larger than one resource block (RB) set. For example, wideband operation may include operation in a channel larger than 20 megahertz (MHz). In some embodiments, wideband operation may include operation in a channel where an in-cell guard band can be configured to distinguish individual RB sets.

[0019] When the Tx UE is to resume the wideband COT after a set of S-SSB candidate slots, the Tx UE may repeat the transmission of the S-SSB (as a wideband COT padding signal) in one or more RB sets in which the UE is to resume the wideband COT. However, when the UE transmits multiple S-SSB repetitions (e.g., instances of the S-SSB waveform) in multiple RB sets occupied by the wideband COT, the transmitted power received at the Rx UE may exceed one or more transmitted power thresholds when transmitting at maximum power across the multiple RB sets.

[0020] Various aspects generally relate to power control for COT signaling. Some aspects more specifically relate to initiating a wideband COT and transmitting a plurality of S-SSB repetitions so as not to exceed a transmission power criterion. In some examples, a UE may limit the amount of S-SSB repetitions in different RB sets based at least in part on the UE's maximum transmission power. Additionally or alternatively, a UE may use a transmission power less than the UE's maximum transmission power for transmitting one or more S-SSB repetitions in an anchor RB set. Additionally or alternatively, a UE may use a transmission power less than the UE's maximum transmission power for transmitting one or more S-SSB repetitions in a non-anchor set.

[0021] Certain aspects of the subject matter described in this disclosure can be implemented to realize one or more of the following potential advantages. In some examples, by limiting the amount of S-SSB repetitions or the transmission power of one or more of the S-SSB repetitions, the techniques described can be used to avoid power fluctuation problems at a Rx UE that can cause, among other examples, interference, failure to successfully decode a transmission, or a communication drop. Additionally or alternatively, by allocating transmission power to different S-SSB repetitions so as not to exceed the maximum transmission power, the techniques described can be used to avoid, among other examples, interference, failure to successfully decode a transmission, or a communication drop. In addition, by determining a power configuration for S-SSB repetitions, a Tx UE can avoid power fluctuation problems at a Rx UE.

[0022] Hereafter, various aspects of this disclosure will be described more fully with reference to the accompanying drawings. However, this disclosure can be embodied in many different forms and should not be construed as being limited to any particular structure or function presented throughout this disclosure. Rather, these aspects are provided to make this disclosure sufficient and complete and to fully convey the scope of this disclosure to those skilled in the art. Those skilled in the art should understand that the scope of this disclosure is intended to encompass any aspect of this disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of this disclosure. For example, an apparatus can be implemented or a method can be practiced using any number of aspects described herein. In addition, the scope of this disclosure is intended to encompass any such apparatus or method practiced using other structures, functions, or structures and functions in addition to, or other than, the various aspects of this disclosure described herein. It should be understood that any aspect of this disclosure disclosed herein can be embodied by one or more elements of the claims.

[0023] Next, several embodiments of telecommunications systems are presented with reference to various devices and techniques. These devices and techniques are described in the following “Modes for Carrying Out the Invention” and are shown in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as “Elements”). These Elements may be implemented using hardware, software, or a combination thereof. Whether such Elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.

[0024] While various aspects may be described herein using terms commonly associated with 5G or New Radio (NR) radio access technology (RAT), the aspects of this disclosure may also apply to other RATs, such as 3G RAT, 4G RAT, and / or RATs following 5G (e.g., 6G).

[0025] Figure 1 shows an example of a wireless network 100 as described herein. The wireless network 100 may be, or may include, elements thereof, a 5G (e.g., NR) network and / or a 4G (e.g., Long-Term Evolution (LTE)) network, among other examples. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), one or more UEs 120 (shown as UE120a, UE120b, UE120c, UE120d, and UE120e), and / or other entities. A network node 110 is a network node that communicates with a UE 120. As shown in the figure, a network node 110 may include one or more network nodes. For example, network node 110 may be an aggregated network node, meaning that the aggregated 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). Alternatively, network node 110 may be a non-aggregated network node (sometimes referred to as a non-aggregated base station), meaning that the network node 110 is configured to utilize a protocol stack that is physically or logically distributed among 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)).

[0026] In some examples, network node 110 is a network node such as an RU that communicates with UE 120 via a wireless access link, or includes such network nodes. In some examples, network node 110 is a network node such as a DU that communicates with other network nodes 110 via a fronthaul link or a midhaul link, or includes such network nodes. In some examples, network node 110 is a network node such as a CU that communicates with other network nodes 110 via a midhaul link or with the core network via a backhaul link, or includes such network nodes. In some examples, network node 110 (such as an aggregated network node 110 or an unaggregated network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. Network nodes 110 may include, for example, NR base stations, LTE base stations, node B, eNB (e.g., in 4G), gNB (e.g., in 5G), access points, transmission reception points (TRPs), DUs, RUs, CUs, network mobility elements, core network nodes, network elements, network equipment, RAN nodes, or combinations thereof. In some examples, network nodes 110 may interconnect with each other or with one or more other network nodes 110 within the wireless network 100 using any suitable transport network through various types of fronthaul interfaces, midhaul interfaces and / or backhaul interfaces, such as direct physical connections, air interfaces, or virtual networks.

[0027] In some examples, network node 110 may provide communication coverage to a specific geographic area. In the Third Generation Partnership Project (3GPP), the term “cell” may refer to the coverage area of ​​network node 110 and / or the network node subsystems serving this coverage area, depending on the context in which the term is used. Network node 110 may provide communication coverage for macrocells, picocells, femtocells, and / or other types of cells. A macrocell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by UEs 120 subscribing to the service. A picocell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 subscribing to the service. A femtocell may cover a relatively small geographic area (e.g., a home) and may allow limited access by UEs 120 associated with that femtocell (e.g., UEs 120 within a closed subscriber group, CSG). A network node 110 for a macrocell may be referred to as a macronetwork node. A network node 110 for a picocell may be referred to as a piconetwork node. A network node 110 for a femtocell may be referred to as a femtonetwork node or home network node. In the example shown in Figure 1, network node 110a can be a macronetwork node for macrocell 102a, network node 110b can be a piconetwork node for picocell 102b, and network node 110c can be a femtonetwork node for femtocell 102c. A network node may support one or more (e.g., three) cells. In some embodiments, cells may not necessarily be fixed, and the geographical area of ​​a cell may move according to the location of a mobile network node 110 (e.g., a mobile network node).

[0028] In some embodiments, the terms “base station” or “network node” may refer to an aggregated base station, a non-aggregated base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some embodiments, “base station” or “network node” may refer to a CU, DU, 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 embodiments, the terms “base station” or “network node” may refer to a single device configured to perform one or more functions, such as those described herein in relation to network node 110. In some embodiments, the terms “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 several different devices (which may be located at the same or different geographical locations) may be configured to perform at least a portion of a function, or to replicate the performance of at least a portion of a function, and the terms “base station” or “network node” may refer to any one or more of those different devices. In some embodiments, the terms “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 embodiments, two or more base station functions may be instantiated on a single device. In some embodiments, the terms “base station” or “network node” may refer to one of the base station functions and not another. In this way, a single device may contain two or more base stations.

[0029] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive data transmissions from upstream nodes (e.g., network node 110 or UE 120) and transmit that data to downstream nodes (e.g., UE 120 or network node 110). A relay station can be a UE 120 that can relay transmissions to other UE 120s. In the embodiment shown in Figure 1, network node 110d (e.g., a relay network node) can communicate with network node 110a (e.g., a macro network node) and UE 120d to facilitate communication between them. The network node 110 that relays communications may be referred to as a relay station, relay base station, relay network node, relay node, repeater, etc.

[0030] The wireless network 100 may be a heterogeneous network including different types of network nodes 110, such as macronetwork nodes, piconetwork nodes, femtonetwork nodes, and relay network nodes. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different effects on interference within the wireless network 100. For example, macronetwork nodes may have high transmit power levels (e.g., 5 to 40 watts), while piconetwork nodes, femtonetwork nodes, and relay network nodes may have lower transmit power levels (e.g., 0.1 to 2 watts).

[0031] The network controller 130 may be coupled to or communicate with a set of network nodes 110, and may provide coordination and control over these network nodes 110. The network controller 130 may communicate with the network nodes 110 via backhaul or midhaul communication links. The network nodes 110 may communicate with each other directly or indirectly via wireless or wireline backhaul communication links. In some embodiments, the network controller 130 may be a CU or core network device, or may include a CU or core network device.

[0032] The UE120 can be distributed throughout the entire wireless network 100, and each UE120 can be fixed or mobile. The UE120 may include, for example, access terminals, terminals, mobile stations, and / or subscriber units. UE120 may be a mobile phone (e.g., a smartphone), a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a wireless local loop (WLL) station, a tablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smart wristband, smart jewelry (e.g., a smart ring or 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, 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.

[0033] Some UE120s can be considered Machine-Type Communication (MTC) UEs, or evolved or enhanced Machine-Type Communication (eMTC) UEs. Examples of MTC UEs and / or eMTC UEs include robots, unmanned aerial vehicles, remote devices, sensors, meters, monitors, and / or location tags that can communicate with network nodes, other devices (e.g., remote devices), or any other entities. Some UE120s may be considered Internet-of-Things (IoT) devices and / or implemented as NB-IoT (narrowband IoT) devices. Some UE120s can be considered customer premises equipment. A UE120 may be contained within a housing that accommodates its components, such as processor components and / or memory components. In some examples, the processor components and memory components may be coupled to each other. For example, processor components (e.g., one or more processors) and memory components (e.g., memory) can be operably coupled, communicatively coupled, electronically coupled, and / or electrically coupled.

[0034] In general, any number of wireless networks 100 can be deployed within a given geographical area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as wireless technology, air interface, etc. Frequencies may be referred to as carriers, frequency channels, etc. To avoid interference between wireless networks of different RATs, each frequency may support a single RAT within a given geographical area. In some cases, NR or 5G RAT networks may be deployed.

[0035] In some embodiments, two or more UE120s (e.g., indicated as UE120a and UE120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary for communication with each other). For example, UE120s may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such embodiments, UE120s may perform scheduling operations, resource selection operations, and / or other operations described elsewhere in this specification as being performed by network node 110.

[0036] Devices in wireless network 100 can communicate using the electromagnetic spectrum, which can be subdivided into various classes, bands, channels, etc., depending on frequency or wavelength. For example, devices in wireless network 100 can communicate using one or more operating bands. In 5G NR, two initial operating bands are defined as frequency range designations FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). It should be understood that although a portion of FR1 is higher than 6 GHz, FR1 is often referred to (interchangeably) as the "sub-6 GHz" band in various documents and papers. A similar nomenclature issue may arise with respect to FR2, which is often referred to (interchangeably) as the "millimeter wave" band in documents and papers, even though it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) which is identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0037] The frequencies between FR1 and FR2 are often referred to as intermediate band frequencies. Recent 5G NR research defines the operating band for these intermediate band frequencies as the frequency range designation FR3 (7.125 GHz to 24.25 GHz). The frequency bands included within FR3 may inherit the FR1 and / or FR2 characteristics, and thus, in effect, the features of FR1 and / or FR2 can be extended to the intermediate band frequencies. In addition, higher frequency bands are currently being considered to extend 5G NR operation beyond 52.6 GHz. For example, three higher operating bands have been defined as the frequency range designations FR4a or FR4-1 (52.6 GHz to 71 GHz), FR4 (52.6 GHz to 114.25 GHz), and FR5 (114.25 GHz to 300 GHz). Each of these higher frequency bands falls within the EHF band.

[0038] With the above examples in mind, please understand that, unless otherwise specified, terms such as "sub-6GHz" may broadly refer to frequencies that may be below 6GHz, frequencies that may be within the FR1 range, or frequencies that may include intermediate band frequencies. Furthermore, please understand that, unless otherwise specified, terms such as "millimeter wave" may broadly refer to frequencies that may include intermediate band frequencies, frequencies that may be within the FR2, FR4, FR4-a or FR4-1, and / or FR5 ranges, or frequencies that may be within the EHF band. The frequencies included within these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are intended to be applicable to those modified frequency ranges.

[0039] In some embodiments, the UE 120 may include a communications manager 140. As described in more detail elsewhere in this specification, the communications manager 140 may initiate broadband channel occupancy time (COT) associated with a plurality of resource block (RB) sets and transmit a plurality of sidelink synchronization signal block (S-SSB) repetitions in at least a portion of the plurality of RB sets occupied by the broadband COT, the amount of S-SSB repetitions among the plurality of S-SSB repetitions, or the transmit power of at least one S-SSB repetition among the plurality of S-SSB repetitions, is at least in part based on power control parameters. Additionally or alternatively, the communications manager 140 may perform one or more other operations described herein.

[0040] As stated above, Figure 1 is provided as an example. Other embodiments may differ from those described with respect to Figure 1.

[0041] Figure 2 shows one embodiment 200 of a network node 110 communicating with a UE 120 within 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 (T≧1) antennas. The UE 120 may be equipped with a set of antennas 252a to 252r, such as R (R≧1) antennas. The network node 110 in Example 200 includes one or more radio frequency components, such as antenna 234 and modem 232. 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 radio frequency components that facilitate direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0042] At network node 110, the transmit processor 220 may receive data from data source 212 addressed to UE120 (or a set of UE120s). The transmit processor 220 may select one or more modulation and coding schemes (MCSs) for the UE120, at least in part on one or more channel quality indicators (CQIs) received from the UE120. The network node 110 may process (e.g., encode and modulate) the data for the UE120, at least in part on the selected MCS(s) for the UE120, and may provide data symbols to the UE120. The transmit processor 220 may process system information (e.g., related to semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, authorizations, and / or upper-layer signaling), and may 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, where applicable, perform spatial processing (e.g., precoding) on ​​data symbols, control symbols, overhead symbols, and / or reference symbols, and may provide a set of output symbol streams (e.g., T output symbol streams) to the corresponding set of modems 232 (e.g., T modems) indicated as modems 232a to 232t. For example, each output symbol stream may be provided to the modulator component of modem 232 (indicated as MOD).Each modem 232 may acquire an output sample stream by processing the corresponding output symbol stream (for example, for OFDM) using the corresponding modulator component. Each modem 232 may further acquire a downlink signal by processing the output sample stream (for example, converting it to analog, amplifying it, filtering it, and / or upconverting it) using the corresponding modulator component. Modems 232a to 232t may transmit a set of downlink signals (for example, T downlink signals) over the corresponding set of antennas 234 (for example, T antennas) indicated as antennas 234a to 234t.

[0043] In UE120, a set of antennas 252 (indicated as antennas 252a to 252r) may receive downlink signals from 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) indicated as modems 254a to 254r. For example, each received signal may be provided to a demodulator component of modem 254 (indicated as DEMOD). Each modem 254 may acquire input samples by modifying the received signals (e.g., filtering, amplifying, downconverting, and / or digitizing) using the corresponding demodulator component. Each modem 254 may further process the input samples (e.g., for OFDM) using the demodulator component to acquire received symbols. A MIMO detector 256 is capable of acquiring received symbols from modem 254, performing MIMO detection on the received symbols where applicable, and providing the detected symbols. The receiving processor 258 may process the detected symbols (e.g., demodulate and decode), provide the decoded data for UE120 to the data sink 260, and provide the decoded control 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, among other examples, determine the reference signal received power (RSRP) parameter, the received signal strength indicator (RSSI) parameter, the reference signal received quality (RSRQ) parameter, and / or the CQI parameter. In some examples, one or more components of UE120 may be contained within the housing 284.

[0044] The network controller 130 may include a communication unit 294, a controller / processor 290, and memory 292. The network controller 130 may include, for example, one or more devices in the core network. The network controller 130 may communicate with the network node 110 via the communication unit 294.

[0045] One or more antennas (for example, antennas 234a-234t and / or antennas 252a-252r) may include, or be included in, one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, among other examples. An antenna panel, antenna group, set of antenna elements, and / or antenna array may include one or more antenna elements (in a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and / or one or more antenna elements coupled to one or more transmitting and / or receiving components, such as one or more components in Figure 2.

[0046] On the uplink, in UE120, the transmit processor 264 may receive and process data from data source 262 and control information from controller / processor 280 (e.g., for reporting, 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 precoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of UE120 may include a modulator and demodulator. In some examples, UE120 includes a transceiver. The transceiver may include any combination of antenna(s) 252, modem(s) 254, MIMO detector 256, receive processor 258, transmit processor 264, and / or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller / processor 280) and memory 282 to perform any of the methods described herein (see, for example, Figures 8 to 10).

[0047] In network node 110, uplink signals from UE 120 and / or other UEs may be received by antenna 234, processed by modem 232 (e.g., the demodulator component of modem 232, shown as DEMOD), detected by MIMO detector 236 where applicable, and further processed by receiving processor 238 to obtain decoded data and control information sent by UE 120. The receiving processor 238 may provide the decoded data to data sink 239 and the decoded control information to controller / processor 240. Network node 110 may include a communication unit 244, which can communicate with network controller 130. Network node 110 may include a scheduler 246 for scheduling one or more UE 120 for downlink and / or uplink communication. In some examples, the modem 232 of network node 110 may include a modulator and a demodulator. In some examples, network node 110 includes a transceiver. The transceiver may include any combination of an antenna(s) 234, a modem(s) 232, a MIMO detector 236, a receiving processor 238, a transmitting processor 220, and / or a TX MIMO processor 230. The transceiver may be used by a processor (e.g., a controller / processor 240) and memory 242 to perform any aspect of the methods described herein (see, for example, Figures 8 to 10).

[0048] As described in more detail elsewhere in this specification, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or any other component(s) in Figure 2 may perform one or more techniques associated with the power configuration for COT signaling. For example, the controller / processor 240 of network node 110, the controller / processor 280 of UE 120, and / or any other component(s) in Figure 2 may perform or direct the operation of, for example, process 900 in Figure 9 and / or other processes as described herein. Memories 242 and 282 may store data and program code for network node 110 and UE 120, respectively. In some embodiments, memory 242 and / or memory 282 may include non-temporary computer-readable media storing one or more instructions (e.g., code and / or program code) for wireless communication. For example, when one or more instructions are executed by one or more processors of the network node 110 and / or UE 120 (for example, directly or after compilation, translation, and / or interpretation), one or more processors, UE 120, and / or network node 110 may be caused to perform or direct the operation of, for example, process 900 in Figure 9 and / or other processes described herein. In some examples, executing an instruction may include, among other examples, running the instruction, translating the instruction, compiling the instruction, and / or interpreting the instruction.

[0049] In some embodiments, the UE120 includes means for initiating a broadband COT associated with a plurality of RB sets, and / or means for transmitting a plurality of S-SSB repetitions in at least a portion of the plurality of RB sets occupied by the broadband COT, wherein the amount of S-SSB repetitions among the plurality of S-SSB repetitions, or the transmit power of at least one S-SSB repetition among the plurality of S-SSB repetitions, is at least partially based on power control parameters. Means for the UE120 to perform the operations described herein may include, for example, one or more of the following: a communications manager 140, an antenna 252, a modem 254, a MIMO detector 256, a receiving processor 258, a transmitting processor 264, a TX MIMO processor 266, a controller / processor 280, or a memory 282.

[0050] In some embodiments, individual processors may perform all functions described as being performed by one or more processors. In some embodiments, one or more processors may collectively perform a set of functions. For example, a first set of processors (one or more) among the one or more processors may perform a first function described as being performed by one or more processors, and a second set of processors (one or more) among the one or more processors may perform a second function described as being performed by one or more processors. The first set of processors and the second set of processors may be the same set of processors or different sets of processors. It should be understood that the reference to “one or more processors” refers to any one or more of the processors described in relation to Figure 2. It should be understood that the reference to “one or more memory” refers to any one or more memory in the corresponding device, such as the memory described in relation to Figure 2. For example, a function described as being performed by one or more memory may be performed by the same subset of one or more memory, or by different subsets of one or more memory.

[0051] Although the blocks in Figure 2 are shown as individual components, the functions described above with respect to these blocks may be implemented in a single hardware, software, or combination of components, or in various combinations of components. For example, the functions 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.

[0052] As stated above, Figure 2 is provided as an example. Other embodiments may differ from those described with respect to Figure 2.

[0053] The deployment of communication systems such as 5G NR systems can be arranged in multiple ways using various components or parts. In a 5G NR system or network, network nodes, network entities, network mobility elements, RAN nodes, core network nodes, network elements, base stations, or network equipment can be implemented in an aggregated or unaggregated architecture. For example, a base station (e.g., among other examples, Node B (NB), evolved NB (eNB), NR base station, 5G NB, access point (AP), TRP, or cell), or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also known as a standalone base station or a monolithic base station) or an unaggregated base station. "Network entity" or "network node" may refer to an unaggregated base station, or to one or more units of an unaggregated base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).

[0054] An aggregated base station (e.g., an aggregated network node) may be configured to utilize a radio protocol stack that is physically or logically integrated within a single RAN node (e.g., within a single device or unit). A non-aggregated base station (e.g., a non-aggregated network node) may be configured to utilize a protocol stack that is physically or logically distributed among 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, 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), among other examples.

[0055] The operation or network design of a base station type may take into account the aggregation characteristics of base station functionality. For example, by utilizing non-aggregated base stations in an IAB network, an open radio access network (O-RAN, such as a network configuration supported by the O-RAN Alliance), or a virtualized radio access network (vRAN, also known as a cloud radio access network, or C-RAN), the scaling of the communication system can be facilitated by separating base station functionality into one or more units that can be deployed individually. A non-aggregated base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually in at least one unit, thereby enabling flexibility in network design. Various units of a non-aggregated base station can be configured to communicate with at least one other unit of the non-aggregated base station via wired or wireless communication.

[0056] Figure 3 shows an exemplary non-aggregated base station architecture 300 according to the present disclosure. The non-aggregated base station architecture 300 may include a CU 310 that can communicate directly with the core network 320 via a backhaul link, or indirectly with the core network 320 via one or more non-aggregated control units (e.g., a quasi-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a Service Management and Orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DU 330 via separate midhaul links, for example, via an F1 interface. Each DU 330 may communicate with one or more RU 340 via separate fronthaul links. Each RU 340 may communicate with one or more UE 120 via its respective radio frequency (RF) access link. In some implementations, the UE 120 may be serviced simultaneously by multiple RU 340s.

[0057] Each of the units, including CU310, DU330, RU340, and the quasi-RT RIC325, non-RT RIC315, and SMO framework 305, may include, or be coupled to, one or more interfaces configured to receive or transmit signals, data, or information (collectively, signals) via a wired or wireless transmitting medium. A related processor or controller providing instructions to each of the units, or to one or more communication interfaces of individual units, may be configured to communicate with one or more of the other units via a transmitting medium. In some embodiments, each of the units may include a wired interface configured to receive or transmit signals via a wired transmission medium to one or more of the other units, and a wireless interface which may include a receiver, transmitter, or transceiver (such as an RF transceiver) configured to receive or transmit or receive signals via a wireless transmitting medium to one or more of the other units.

[0058] In some embodiments, the CU310 may host one or more higher-layer control functions. Such control functions include, among other examples, radio resource control (RRC), packet data convergence protocol (PDCP), or service data adaptation protocol (SDAP). Each control function may be implemented using an interface configured to communicate signals with other control functions hosted by the CU310. The CU310 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 implementations, the CU310 may be logically divided 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 can communicate bidirectionally with the CU-CP unit via an interface such as the E1 interface. The CU310 can be implemented to communicate with the DU330 as needed for network control and signaling.

[0059] Each DU330 may correspond to a logic unit containing one or more base station functions for controlling the operation of one or more RU340s. In some embodiments, the DU330 can host one or more of the radio link control (RLC) layer, the medium access control (MAC) layer, and one or more upper physical (PHY) layers, at least in part according to a functional partition such as a functional partition as defined by 3GPP. In some embodiments, one or more upper PHY layers may be implemented by one or more modules for forward error correction (FEC) coding and decoding, scrambling, and modulation and demodulation, among other examples. In some embodiments, the DU330 can further host one or more lower-level PHY layers, such as those implemented by one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming, or physical random access channel (PRACH) extraction and filtering, among other examples. Each layer (sometimes referred to as a module) can be implemented using an interface configured to communicate signals with other layers (and modules) hosted by the DU330, or with control functions hosted by the CU310.

[0060] Each RU340 can perform lower-layer functionality. In some deployments, a RU340 controlled by a DU330 may correspond to a logical node hosting RF processing functions or lower PHY layer functions such as performing FFT, iFFT, digital beamforming, or PRACH extraction and filtering, based on functional partitioning (e.g., functional partitioning as defined by 3GPP), among other examples. In such architectures, each RU340 can operate to handle over-the-air (OTA) communication with one or more UE120s. In some implementations, the real-time and non-real-time modes of control plane communication and user plane communication with the RU340(one or more) can be controlled by the corresponding DU330. In some scenarios, this configuration can enable each DU330 and CU310 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.

[0061] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which can be managed via an operation and maintenance interface (such as the O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as the open cloud (O-Cloud) platform 390) to perform lifecycle management of the network elements (such as instantiating virtualized network elements) via a cloud computing platform interface (such as the O2 interface). Such virtualized network elements may include, but are not limited to, the CU310, DU330, RU340, non-RT RIC315, and quasi-RT RIC325. In some implementations, the SMO framework 305 can communicate with hardware embodiments of the 4G RAN, such as the open eNB (O-eNB) 311, via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of one or more RU340s via a separate O1 interface. The SMO framework 305 may also include a non-RT RIC315 configured to support the functionality of the SMO framework 305.

[0062] Non-RT RIC315 may be configured to include logical functions that enable policy-based guidance for non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or applications / functions in quasi-RT RIC325. Non-RT RIC315 can be coupled to or communicate with quasi-RT RIC325 (via the A1 interface, for example). Quasi-RT RIC325 may be configured to include logical functions that enable quasi-real-time control and optimization of RAN elements and resources through data acquisition and action via an interface connecting one or more CU310s, one or more DU330s, or both, and an O-eNB to the quasi-RT RIC325 (via the E2 interface, for example).

[0063] In some implementations, the non-RT RIC315 may receive parameter or external enrichment information from an external server to generate an AI / ML model to be deployed in the quasi-RT RIC325. Such information can be utilized by the quasi-RT RIC325 and may be received in the SMO framework 305 or the non-RT RIC315 from a non-network data source or from a network function. In some examples, the non-RT RIC315 or quasi-RT RIC325 may be configured to tune the behavior or performance of the RAN. For example, the non-RT RIC315 may monitor long-term trends and patterns in performance and employ an AI / ML model to take corrective action through the SMO framework 305 (e.g., reconfiguration via the O1 interface) or by creating a RAN management policy (e.g., an A1 interface policy).

[0064] As stated above, Figure 3 is provided as an example. Other embodiments may differ from those described with respect to Figure 3.

[0065] Figure 4 shows an embodiment 400 of the synchronization signal (SS) hierarchy according to the present disclosure. As shown in Figure 4, the SS hierarchy may include an SS burst set 405, which may include a plurality of SS bursts 410, indicated 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 transmitted by one or more network nodes. Further as shown, each SS burst 410 may include one or more SSB blocks (SS blocks, SSBs) 415, indicated as SSB0 to SSB M-1, where M is the maximum number of SSBs 415 that can be carried by the SS burst 410. In some embodiments, different SSBs 415 may be beamformed differently (e.g., transmitted using different beams) and may be used for cell discovery, 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 transmitted periodically by a wireless node (e.g., network node 110), such as every X milliseconds, as shown in Figure 4. In some embodiments, the SS burst set 405 may have a fixed or dynamic length, shown as Y milliseconds in Figure 4. In some cases, the SS burst set 405 or SS burst 410 may be called a discovery reference signal (DRS) transmission window or an SSB measurement time configuration (SMTC) window.

[0066] In some embodiments, SSB415 may include resources that carry a primary synchronization signal (PSS) 420, a secondary synchronization signal (SSS) 425, and / or a physical broadcast channel (PBCH) 430. In some embodiments, multiple SSB415s are included in an SS burst 410 (e.g., using transmissions on different beams), and the PSS420, SSS425, and / or PBCH430 may be the same across each SSB415 in the SS burst 410. In some embodiments, a single SSB415 may be included in the SS burst 410. In some embodiments, SSB415 may have a length of at least four symbols (e.g., OFDM symbols), and each symbol carries one or more of the PSS420 (e.g., occupying one symbol), SSS425 (e.g., occupying one symbol), and / or PBCH430 (e.g., occupying two symbols). In some embodiments, SSB415 may be referred to as an SS / PBCH block.

[0067] In some embodiments, the symbols of SSB415 are consecutive, as shown in Figure 4. In some embodiments, the symbols of SSB415 are not consecutive. Similarly, in some embodiments, one or more SSB415s of SS burst 410 may be transmitted in consecutive radio resources (e.g., consecutive symbols) between one or more slots. As an addition or alternative, one or more SSB415s of SS burst 410 may be transmitted in non-contiguous radio resources.

[0068] In some embodiments, an SS burst 410 may have a burst period, and the SSB 415 of the SS burst 410 may be transmitted by a wireless node (e.g., a network node 110) according to the burst period. In this case, the SSB 415 may be repeated between each SS burst 410. In some embodiments, an SS burst set 405 may have a burst set period, thereby the SS bursts 410 of the SS burst set 405 are transmitted by a wireless node according to a fixed burst set period. In other words, an SS burst 410 may be repeated between each SS burst set 405.

[0069] In some embodiments, the SSB415 may include an SSB index that may correspond to the beam used to carry the SSB415. The Rx UE may monitor and / or measure the SSB415 using different receiving (Rx) beams during the access procedure, among other examples. Based at least in part on monitoring and / or measurement, the Rx UE may indicate to the Tx UE one or more SSB415s having the best signal parameters (e.g., reference signal received power (RSRP) parameters). The Rx UE and Tx UE may use one or more indicated SSB415s to select one or more beams to be used for communication. As an addition or alternative, the UE may use the SSB415 and / or SSB index to determine the cell timing for the resource through which the SSB415 is received.

[0070] As stated above, Figure 4 is provided as an example. Other embodiments may differ from those described with respect to Figure 4.

[0071] Figure 5 shows one embodiment 500 of sidelink communication according to the present disclosure.

[0072] As shown in Figure 5, the first UE505-1 may communicate with the second UE505-2 (and one or more other UE505s) via one or more sidelink channels 510. UE505-1 and 505-2 may communicate using one or more sidelink channels 510 for P2P communication, D2D communication, V2X communication (which may include, for example, V2V communication, V2I communication, and / or V2P communication), and / or mesh networking. In some embodiments, the UE505 (e.g., UE505-1 and / or UE505-2) may correspond to one or more other UEs described elsewhere in this specification, such as UE120. In some embodiments, one or more sidelink channels 510 may use the PC5 interface and / or operate in a high-frequency band (e.g., the 5.9 GHz band). As an addition or alternative, the UE505 may use global navigation satellite system (GNSS) timing to synchronize the timing of transmission time intervals (TTIs) (e.g., frames, subframes, slots, or symbols).

[0073] As further shown in Figure 5, one or more sidelink channels 510 may include a physical sidelink control channel (PSCCH) 515, a physical sidelink shared channel (PSSCH) 520, and / or a physical sidelink feedback channel (PSFCH) 525. The PSCCH 515 may be used to communicate control information, similar to the physical downlink control channel (PDCCH) and / or physical uplink control channel (PUCCH) used for cellular communication with the network node 110 over an access link or access channel. The PSSCH 520 may be used to communicate data, similar to the physical downlink shared channel (PDSCH) and / or physical uplink shared channel (PUSCH) used for cellular communication with the network node 110 over an access link or access channel. For example, PSCCH515 may carry sidelink control information (SCI)530, which may represent various control information used for sidelink communication, such as one or more resources (e.g., time resources, frequency resources, and / or spatial resources), in which case a transport block (TB)535 may be carried on PSCCH520. TB535 may contain data.The PSFCH525 may be used to communicate sidelink feedback 540 such as hybrid automatic repeat request (HARQ) feedback (e.g., acknowledgment or negative acknowledgement (ACK / NACK) information), transmit power control (TPC), and / or scheduling request (SR).

[0074] As shown on PSCCH515, in some embodiments, SCI530 may include multiple communications in different stages, such as a first-stage SCI (SCI-1) and a second-stage SCI (SCI-2). SCI-1 may be transmitted on PSCCH515. SCI-2 may be transmitted on PSSCH520. SCI-1 may include, for example, an indication of one or more resources on PSSCH520 (e.g., time resources, frequency resources, and / or spatial resources), information for decoding sidelink communications on PSSCH, a quality of service (QoS) priority value, a resource reservation period, a PSSCH demodulation reference signal (DMRS) pattern, an SCI format for SCI-2, a beta offset for SCI-2, a PSSCH DMRS port amount, and / or a modulation and coding scheme (MCS). SCI-2 may include information associated with data transmission on the PSSCH520, such as the Hybrid Automatic Retransmission Request (HARQ) process ID, new data indicator (NDI), source identifier, destination identifier, and / or channel state information (CSI) reporting trigger.

[0075] In some embodiments, one or more sidelink channels 510 may use a resource pool. For example, a scheduling assignment (e.g., included in SCI530) may be transmitted on a subchannel using specific resource blocks (RBs) over time. In some embodiments, a data transmission associated with a scheduling assignment (e.g., on PSSCH520) may occupy adjacent RBs in the same subframe as the scheduling assignment (e.g., using frequency division multiplexing). In some embodiments, neither the scheduling assignment nor the associated data transmission is transmitted on adjacent RBs.

[0076] In some embodiments, the UE505 may operate using a sidelink transmit mode (e.g., Mode 1), in which case resource selection and / or scheduling is performed by the network node 110 (e.g., base station, CU, or DU). For example, the UE505 may receive grants from the network node 110 (e.g., directly or via one or more network nodes) for sidelink channel access and / or scheduling (e.g., for configured grants, in downlink control information (DCI) or in radio resource control (RRC) messages). In some embodiments, the UE505 may operate using a transmit mode (e.g., Mode 2), in which case resource selection and / or scheduling is performed by the UE505 (rather than the network node 110). In some embodiments, the UE505 may perform resource selection and / or scheduling by sensing channel availability for transmission. For example, the UE505 can measure received signal strength indicator (RSSI) parameters associated with various sidelink channels (e.g., sidelink-RSSI, S-RSSI) parameters, measure reference signal received power (RSRP) parameters associated with various sidelink channels (e.g., PSSCH-RSRP parameters), and / or measure reference signal received quality (RSRQ) parameters associated with various sidelink channels (e.g., PSSCH-RSRQ parameters), and can select a channel for transmitting sidelink communication at least in part based on the measurement(s).

[0077] As an addition or alternative, UE505 may perform resource selection and / or scheduling using SCI530 received in PSCCH515, which may indicate occupied resources and / or channel parameters. As an addition or alternative, UE505 may perform resource selection and / or scheduling by determining the channel busy ratio (CBR) associated with various sidelink channels, which may be used for rate control (for example, by indicating the maximum number of resource blocks that UE505 can use for a particular set of subframes).

[0078] In transmit modes where resource selection and / or scheduling are performed by UE505, UE505 may generate sidelink permissions and transmit those permissions in SCI530. A sidelink permission may indicate one or more resource blocks to be used for the next sidelink transmit on PSSCH520 (e.g., for TB535), one or more subframes to be used for the next sidelink transmit, and / or one or more parameters to be used for the next sidelink transmit (e.g., transmit parameters), such as the modulation and coding scheme (MCS) to be used for the next sidelink transmit. In some embodiments, UE505 may generate sidelink permissions indicating one or more parameters for semi-persistent scheduling (SPS), such as the periodicity of the sidelink transmit. As an addition or alternative, UE505 may generate sidelink permissions for event-driven scheduling, such as for on-demand sidelink messages.

[0079] As stated above, Figure 5 is provided as an example. Other embodiments may differ from those described with respect to Figure 5.

[0080] Figure 6 shows an embodiment 600 of side-link communication and access-link communication according to the present disclosure.

[0081] As shown in Figure 6, the transmitter (Tx) / receiver (Rx) UE605 and Rx / Tx UE610 can communicate with each other via sidelinks, as described above with respect to Figure 5. As further shown, in some sidelink modes, network node 110 can communicate with Tx / Rx UE605 (e.g., directly or via one or more network nodes), such as via a first access link. Additionally or alternatively, in some sidelink modes, network node 110 can communicate with Rx / Tx UE610 (e.g., directly or via one or more network nodes), such as via a first access link. Tx / Rx UE605 and / or Rx / Tx UE610 may correspond to one or more UEs described elsewhere in this specification, such as UE120 in Figure 1. Therefore, a direct link between UE120s (e.g., via the PC5 interface) may be called a sidelink, and a direct link between network 110 and UE120 (e.g., via the Uu interface) may be called an access link. Sidelink communication may be transmitted via a sidelink, and access link communication may be transmitted via an access link. Access link communication may be either downlink communication (from network node 110 to UE120) or uplink communication (from UE120 to network node 110).

[0082] As stated above, Figure 6 is provided as an example. Other embodiments may differ from those described with respect to Figure 6.

[0083] Figure 7 shows an embodiment 700 of a broadband channel occupancy time (COT) padding signal according to the present disclosure.

[0084] As shown in Figure 7, a Tx UE may occupy a COT across multiple RB sets, such as a first RB set (RB set 0) and a second RB set (RB set 1). The Tx UE may use the COT to transmit one or more communications, such as a set of PSSCH communications and / or S-SSB communications. S-SSB communications may include a first S-SSB communications for a first type of Rx UE (e.g., legacy S-SSB for a legacy Rx UE) and a second S-SSB communications for a second type of Rx UE (e.g., additional S-SSB for an Rx UE with additional agreed-upon features such as carrier-specific features or next-generation / release features). The Tx UE may repeat transmissions across multiple RB sets. For example, the UE may transmit legacy S-SSB on RB set 0 and RB set 1.

[0085] As stated above, Figure 7 is provided as an example. Other embodiments may differ from those described with respect to Figure 7.

[0086] One example of COT use is in the unlicensed spectrum. In the unlicensed spectrum, prior to gaining access to an unlicensed channel and / or transmitting over it, a UE with a packet to transmit may need to perform a listen-before-talk (LBT) procedure to compete for access to the unlicensed channel. The LBT procedure may include detecting the energy level on the unlicensed channel and determining whether the energy level satisfies a threshold (e.g., is below it), sometimes called an energy detection threshold. When the energy level satisfies the threshold (e.g., is below it), the UE may gain access to the unlicensed channel for a duration that may be called COT, during which the UE can transmit without performing any additional LBT operations.

[0087] For example, when communicating over a sidelink in an unlicensed spectrum, the Tx UE may transmit an S-SSB transmission to carry configuration information to the Rx UE. The Tx UE may repeat the S-SSB across multiple resource block (RB) sets, such as on anchored RB sets and unanchored RB sets, to maintain broadband COT across a set of S-SSB candidate slots. In this case, the Tx UE repeats the S-SSB waveform in all candidate S-SSB slots within the COT after clearing the LBT procedure. When the Tx UE will resume broadband COT after a set of S-SSB candidate slots, the Tx UE may repeat the S-SSB transmission (as broadband COT padding signal) in one or more RB sets where the UE will resume broadband COT. However, when a UE transmits multiple S-SSB iterations (e.g., instances of an S-SSB waveform) across multiple RB sets occupied by a broadband COT, the transmit power received by the Rx UE may exceed one or more transmit power thresholds when transmitting at maximum power across multiple RB sets.

[0088] Various embodiments generally relate to power control for COT signaling. Some embodiments more specifically relate to initiating broadband COT and transmitting multiple S-SSB repetitions so as not to exceed a transmit power criterion. In some embodiments, the UE may limit the amount of S-SSB repetitions in different RB sets based at least in part on the UE's maximum transmit power. Additional or alternative, the UE may use a transmit power lower than the UE's maximum transmit power for transmitting one or more S-SSB repetitions in an anchor RB set. Additional or alternative, the UE may use a transmit power lower than the UE's maximum transmit power for transmitting one or more S-SSB repetitions in non-anchor sets.

[0089] Certain aspects of the subject matter described herein can be implemented to achieve one or more of the following potential benefits. In some embodiments, by limiting the number of S-SSB iterations or the transmit power of one or more of the S-SSB iterations, the techniques described can be used, among other examples, to avoid power fluctuation problems in the Rx UE (e.g., physical sidelink broadcast channel (PSBCH) reference signal received power (RSRP) fluctuations) which can result in interference, failure to successfully decode the transmission, or communication drops.

[0090] Figure 8 shows one embodiment 800 associated with the power configuration of COT signaling according to the present disclosure. As shown in Figure 8, embodiment 800 includes communication between Tx UE120 and Rx UE120.

[0091] As further shown in Figure 8 by reference no. 810, the Tx UE120 may initiate a COT. For example, the Tx UE120 may perform an LBT procedure to obtain access to a set of resources for one or more channels. In some embodiments, the Tx UE120 may establish a set of anchor RB sets and a set of non-anchor RB sets. For example, in connection with obtaining access to channel resources, the Tx UE120 may determine that a first set of RBs is the anchor RB set and one or more second sets of RBs are non-anchor RB sets. In this case, the Tx UE120 may determine that control signaling and initial setup of communication services (e.g., between the Tx UE120 and one or more possible Rx UE120s) should be performed on the first set of RBs (e.g., assigned as the anchor RB set), and that data communication or backup signaling (e.g., iterations for increased reliability) should be performed on the second set of RBs (e.g., assigned as the non-anchor RB set).

[0092] As further shown in Figure 8 by reference no. 820, Tx UE120 can determine the transmit power configuration. For example, Tx UE120 can determine the transmit power configuration for transmitting repetitions of S-SSB communication. In this case, repetitions of S-SSB communication can refer to each instance of transmission of S-SSB communication. Thus, the first (original) transmission of S-SSB communication can be called the "first repetition," and a second transmission of S-SSB communication (e.g., transmission of the same or different waveforms to communicate the same information) can be called the "second repetition." Furthermore, in some contexts, a set of repetitions can include a single repetition. In other words, Tx UE120 can transmit a single (i.e., only one) transmission of communication which can be called a "repetition" of communication.

[0093] In some embodiments, to determine the transmit power configuration, Tx UE120 may determine a specific number of S-SSB repetitions to transmit to Rx UE120. For example, Tx UE120 may determine its maximum transmit power and limit the number of S-SSB repetitions in different RB sets according to the maximum transmit power (e.g., to avoid power fluctuation problems in reception at Rx UE120). In this case, Tx UE120 may drop or cancel the transmission of one or more repetitions of S-SSB communication in one or more RB sets to limit the total transmit power across all repetitions of S-SSB communication. Alternatively, the number of S-SSB communication repetitions may be based on the amount of available transmit power. In other words, Tx UE120 may allocate transmit power from the maximum transmit power to sets of transmissions according to prioritization. For example, Tx UE120 may allocate transmit power to one or more transmissions on an anchor RB set with a higher relative priority (or allocation order), and allocate the remaining transmit power to one or more transmissions on a non-anchor RB set with a lower relative priority (or allocation order). Therefore, the amount of transmission occurring on a non-anchor RB set may be based on the amount of remaining transmit power. For example, Tx UE120 may have a minimum transmit power to allocate to a transmission, and may allocate transmit power to only the same number of transmissions that can be allocated, such that each allocated transmission has at least the minimum transmit power without exceeding the amount of remaining transmit power.

[0094] As an addition or alternative, to determine the transmit power configuration, the Tx UE120 may adjust the transmit power level of individual repetitions of S-SSB communication. For example, the Tx UE120 may reduce the transmit power of S-SSB repetitions in an anchor RB set (e.g., legacy 11-RB S-SSB transmits). In this case, reducing the transmit power of S-SSB repetitions may be done, at least partially, based on the unlicensed sidelink spectrum used for short-range communication (e.g., in an indoor setting), without adversely impacting S-SSB coverage (e.g., without the Rx UE120 failing to receive S-SSB repetitions in the anchor RB set).

[0095] In some embodiments, the amount by which Tx UE120 reduces transmit power may be based at least in part on specifications (e.g., fixed values), measured values ​​(e.g., signal strength such as the amount of interference or reference signal received power), or signaled parameters (e.g., configuration from another UE120 or from network node 110). In these cases, Tx UE120 may determine an offset value that represents, for example, the amount of transmit power backoff from Tx UE120's maximum transmit power (or some other transmit power threshold). For example, Tx UE120 may set an upper limit on anchor RB set transmit power to 16 decibel milliwatts (dBm) or 13 dBm for a subcarrier spacing of 30 kilohertz (kHz) or 15 kHz, subject to power-spectral density (PSD) limitations.

[0096] As an addition or alternative, Tx UE120 may adjust the transmit power of S-SSB iterations in non-anchor RB sets. For example, Tx UE120 may reduce the transmit power of one or more non-anchor RB set S-SSB iterations to avoid causing power fluctuation problems in Rx UE120. In this case, non-anchor RB set S-SSB iterations may be used for broadband COT padding (for example, to maintain broadband COT as described above). Thus, Tx UE120 may reduce the transmit power of non-anchor RB set S-SSB iterations without causing Rx UE120 to fail to receive S-SSB communications (since Rx UE120 can only monitor S-SSB communications to obtain synchronization information in anchor RB sets). In other words, in relation to Tx UE120 allocating transmit power for transmissions in an anchored RB set, Tx UE120 may allocate the remaining transmit power from the maximum transmit power to transmissions in the non-anchored RB set (for example, by reducing the transmit power for non-anchored RB set S-SSB iterations, as described above). In this embodiment, Tx UE120 may equally allocate the remaining transmit power among transmissions in the non-anchored RB set, or using another allocation technique.

[0097] In some embodiments, the Tx UE120 may perform several different adjustments to determine the transmit power configuration. For example, the Tx UE120 may perform two or more of the following: adjusting the amount of S-SSB repetitions, adjusting the transmit power of anchored RB set S-SSB repetitions, or adjusting the transmit power of non-anchored RB set S-SSB repetitions. In this case, the Tx UE120 may choose which adjustments to perform statically (for example, the Tx UE120 may be configured to adjust the amount of S-SSB repetitions and the transmit power of non-anchored RB set S-SSB repetitions). Alternatively, the Tx UE120 may choose which adjustments to perform dynamically. For example, the Tx UE120 may receive feedback information and switch from performing a single adjustment (for example, adjusting the transmit power of anchored RB set S-SSB repetitions) to performing multiple adjustments (for example, adjusting the transmit power of anchored RB set S-SSB repetitions and non-anchored RB set S-SSB repetitions). As an addition or alternative, the Tx UE120 may periodically reconfigure the adjustments. For example, the Tx UE120 may change the size of the transmit power offset applied to reduce the transmit power of anchored RB set S-SSB iterations. As another example, the Tx UE120 may, in a first time period, apply a first amount of transmit power offset to non-anchored RB set S-SSB iterations and receive feedback information, and in a second time period, apply the same or a different transmit power offset to a second amount of non-anchored RB set S-SSB iterations.

[0098] As further shown in Figure 8 by reference no. 830, the Tx UE120 may transmit sets of S-SSB iterations. For example, the Tx UE120 may transmit one or more anchored RB set S-SSB iterations and / or one or more non-anchored RB set S-SSB iterations using transmit power configured according to the transmit power configuration. Additionally or alternatively, the Tx UE120 may transmit a specific amount of S-SSB iterations according to the transmit power configuration.

[0099] As stated above, Figure 8 is provided as an example. Other embodiments may differ from those described with respect to Figure 8.

[0100] Figure 9 shows an exemplary process 900 performed by, for example, a UE according to the present disclosure. The exemplary process 900 is an embodiment in which a UE (e.g., UE120) performs operations associated with a power configuration for channel occupancy time signaling.

[0101] As shown in Figure 9, in some embodiments, process 900 may include initiating a broadband COT associated with multiple resource block (RB) sets (block 910). For example, a UE (using, for example, the communications manager 1006 shown in Figure 10) may initiate a broadband COT associated with multiple resource block (RB) sets as described above.

[0102] As further shown in Figure 9, in some embodiments, process 900 may include transmitting a plurality of S-SSB repetitions in at least a portion of a plurality of RB sets occupied by the broadband COT, and the amount of S-SSB repetitions among the plurality of S-SSB repetitions, or the transmit power of at least one S-SSB repetition among the plurality of S-SSB repetitions, is at least partially based on power control parameters (block 920). For example, a UE (e.g., using the transmit component 1004 and / or communication manager 1006 shown in Figure 10) may transmit a plurality of S-SSB repetitions in at least a portion of a plurality of RB sets occupied by the broadband COT, and the amount of S-SSB repetitions among the plurality of S-SSB repetitions, or the transmit power of at least one S-SSB repetition among the plurality of S-SSB repetitions, is at least partially based on power control parameters as described above.

[0103] Process 900 may include additional embodiments, such as any single embodiment or any combination of embodiments, which are described below and / or in relation to one or more other processes described elsewhere in this specification.

[0104] In the first embodiment, the amount of S-SSB iterations is based at least in part on the maximum transmit power of the UE.

[0105] In the second embodiment, transmitting multiple S-SSB iterations in at least a portion of a plurality of RB sets, either alone or in combination with the first embodiment, includes transmitting multiple S-SSB iterations in an amount of RB sets less than the amount of RB sets configured in the plurality of RB sets.

[0106] In the third embodiment, either alone or in combination with one or more of the first and second embodiments, the transmit power of at least one S-SSB iteration among multiple S-SSB iterations in an anchor RB set among multiple RB sets is offset from the maximum transmit power by a threshold amount.

[0107] In the fourth embodiment, either alone or in combination with one or more of the first to third embodiments, the transmit power of at least one subset of S-SSB iterations among multiple S-SSB iterations in a non-anchored RB set among multiple RB sets is offset from the maximum transmit power by a threshold amount.

[0108] In the fifth aspect, either alone or in combination with one or more of the first to fourth aspects, at least one S-SSB iteration in a non-anchor RB set is broadband COT padding communication.

[0109] In the sixth aspect, the offset from the maximum transmit power is associated with the anchor RB set transmit power, either alone or in combination with one or more of the first to fifth aspects.

Additionally or alternatively, two or more blocks of process 900 may be executed in parallel.

In some embodiments, the apparatus 1000 may include a receiving component 1002, a transmitting component 1004, and / or a communications manager 1006, which may communicate with each other (e.g., via one or more buses and / or one or more other components). In some embodiments, the communications manager 1006 is the communications manager 140 described in relation to Figure 1. As shown, the apparatus 1000 may use the receiving component 1002 and the transmitting component 1004 to communicate with a UE or another apparatus 1008, such as a network node (CU, DU, RU, or base station).

Additionally or alternatively, one or more components of a set of components may be implemented as software, at least partially stored in memory. For example, a component (or a portion of a component) may be implemented as instructions or code, executable by a processor, that perform the function or operation of the component, and stored in a controller or non-temporary computer-readable medium.

[0113] The receiving component 1002 may receive communications from the device 1008, such as reference signals, control information, data communications, or a combination thereof. The receiving component 1002 may provide the received communications to one or more other components of the device 1000. In some embodiments, the receiving component 1002 may perform signal processing on the received communications (in particular, filtering, amplification, demodulation, analog-to-digital conversion, demultiplexing, deinterleaving, demapping, equalization, interference cancellation, or decoding, among other examples) and provide the processed signals to one or more other components of the device 1000. In some embodiments, the receiving component 1002 may include one or more antennas, modems, demodulators, MIMO detectors, receiving processors, controllers / processors, memory, or a combination thereof, as described in relation to Figure 2.

[0115] The communication manager 1006 may support the operation of the receiving component 1002 and / or the transmitting component 1004.

Additionally or alternatively, the communication manager 1006 may generate control information and / or provide control information to the receiving component 1002 and / or the transmitting component 1004 in order to control the receiving and / or transmitting communications.

[0116] The communication manager 1006 may initiate a broadband COT associated with multiple RB sets. The transmitting component 1004 may transmit multiple S-SSB repetitions in at least a portion of the multiple RB sets occupied by the broadband COT, and the amount of S-SSB repetitions among the multiple S-SSB repetitions, or the transmit power of at least one S-SSB repetition among the multiple S-SSB repetitions, is at least partially based on power control parameters.
