[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims priority to U.S. patent application No. 17 / 933,956, filed on September 21, 2022, entitled "INDICATING NETWORK STATEVIA BANDWIDTH PART FRAMEWORK," which is hereby expressly incorporated herein by reference. Technical Field

[0003] Aspects of the present disclosure relate generally to wireless communications, and more particularly to techniques and apparatus associated with indicating network status via a bandwidth part (BWP) frame. 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 or transmit power). 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] The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different user equipment (UE) to communicate at a city, country, region 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 support mobile broadband Internet access by using orthogonal frequency division multiplexing (OFDM) (CP-OFDM) with a cyclic prefix (CP) on the downlink, using CP-OFDM 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 to improve spectrum efficiency, reduce costs, improve services, utilize new spectrum, and better integrate with other open standards. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful.

[0006] For various reasons, including climate change mitigation, environmental sustainability, and network cost reduction, it is expected that network energy conservation and / or network energy efficiency measures will have increasing importance in wireless network operations. For example, although NR generally provides significant energy efficiency improvements per gigabyte over previous generations (e.g., LTE), the adoption of new NR use cases and / or millimeter wave frequencies may require more network sites, more network antennas, greater bandwidth, and / or more frequency bands, which may potentially lead to more efficient wireless networks, which still have higher energy requirements and / or cause more emissions than previous generations of wireless networks. In addition, energy accounts for a large proportion of the cost of operating wireless networks. For example, according to some estimates, energy costs are about a quarter of the total cost of operating a wireless network, and more than 90% of network operating costs are spent on energy (e.g., fuel and electricity). Most energy consumption and / or energy costs are associated with powering the radio access network (RAN), which accounts for about half of the energy consumed by the wireless network. Therefore, measures to increase network energy conservation and / or network energy efficiency are important factors that can drive the adoption and / or expansion of wireless networks.

[0007] One way to increase energy efficiency in the RAN may be to adapt the network energy consumption model to dynamically and / or semi-statically achieve more efficient operation. For example, power consumption in the RAN may generally be divided into a dynamic part and a static part, in which power is consumed only when data transmission and / or reception is ongoing, and in which power is always consumed to maintain the operation of the radio access equipment even when data transmission and / or reception is not ongoing. Therefore, one potential way to improve network energy saving may be to adapt the power consumption model from a network perspective by reducing the relative energy consumption of downlink and / or uplink communications (e.g., taking into account factors such as power amplifier (PA) efficiency, the number of transceiver units (TxRUs) and / or network load), enabling network sleep states and associated transition times, and / or defining appropriate reference parameters and / or configurations. For example, in some cases, different network energy saving (NES) states may be configured to use techniques in the time domain, frequency domain, spatial domain, and / or power domain to achieve granular adaptation of transmission and / or reception to reduce energy consumption with potential support and / or feedback from UE and / or potential UE assistance information. However, the network device and the UE may need to exchange and / or coordinate information through a network interface to control configuration, communication parameters and / or UE behavior for each NES state, which may increase configuration complexity and / or signaling overhead.

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

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

[0028] Various aspects are generally related to using a bandwidth portion (BWP) framework to indicate a periodic sequence of network energy saving (NES) states. Some aspects are more specifically related to operating a network node under various NES states (e.g., a default or normal mode and one or more sleep or low power modes associated with a configuration for saving power and maintaining network operation), and configuring a periodic BWP switching pattern to indicate a change in the NES state in which the network node operates at any given time. For example, in some aspects, a candidate BWP may be associated with one or more configurations, communication parameters, and / or user equipment (UE) behaviors associated with one or more NES states, whereby a periodic BWP switching pattern may be used to implement switching between different NES states. For example, a network node may configure a UE to have one or more candidate BWPs, and may configure the UE to have a periodic BWP switching pattern to indicate a candidate BWP sequence and / or a configuration sequence associated with a candidate BWP that the network node and the UE are configured to follow when communicating on a downlink and / or uplink. In addition, each candidate BWP and / or each configuration associated with a candidate BWP in the candidate BWP sequence may be associated with a duration for which the corresponding candidate BWP and / or BWP configuration is to remain active. Thus, in some aspects, the network node and the UE may sequentially switch between different BWPs and / or different BWP configurations according to a periodic BWP switching pattern to sequentially switch between different NES states.

[0029] Certain aspects of the subject matter described in the present disclosure may be implemented to achieve one or more of the following potential advantages. In some examples, the described techniques may be used to configure a semi-static approach to reduce network energy consumption by associating each candidate BWP or candidate BWP configuration in a periodic BWP switching pattern with a corresponding NES state. In addition, in some examples, the described techniques may be used to avoid configuring and / or signaling NES states because the candidate BWP or candidate BWP configuration carries configurations, communication parameters, and / or UE behaviors for implementing the corresponding NES states. In addition, in some examples, the described techniques may be used to avoid relying on dynamic BWP switching to change between different candidate BWPs and / or different candidate BWP configurations, which often carries significant overhead from the perspective of signaling and / or UE processing.

[0030] Figure 1 1 is a diagram illustrating an example of a wireless network according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network 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 (NN) 110a, network node 110b, network node 110c, and network node 110d), one UE 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other network entities. The network node 110 is an entity 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)).

[0031] 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, or one or more DUs. The network node 110 may include, for example, an NR network node, an LTE network node, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point or 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, and / or a RAN node. 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 interfaces, midhaul interfaces, or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks) using any suitable transport network.

[0032] Each network node 110 may provide communication coverage for a particular geographic area. In the 3rd Generation Partnership Project (3GPP), the term "cell" may refer to a coverage area of ​​a network node 110 or a network node subsystem serving the coverage area, depending on the context in which the term is used.

[0033] The network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several thousand meters) 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 residence) 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. A network node 110 for a femto cell may be referred to as a femto network node or a home network node.

[0034] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, or relay network nodes. These different types of network nodes 110 may have different transmit power levels, different coverage areas, or different effects 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). 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. The network node may support one or more (e.g., three) cells. In some examples, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., a mobile network node).

[0035] 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), and / or a non-real-time (non-RT) RIC. 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 plurality 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 repeatedly perform 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 another base station function. In this way, a single device may include more than one base station.

[0036] 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. The network nodes 110 may also communicate directly with each other or indirectly via a wireless or wired backhaul communication link. In some aspects, the network controller 130 may be a CU or a core network device, or the network controller 130 may include a CU or a core network device.

[0037] In some examples, the cells may not necessarily be stationary, and the geographic area of ​​the cells may move depending on the location of the mobile network node 110 (e.g., the mobile network node). In some examples, the network nodes 110 may be interconnected with each other or to one or more other network nodes 110 or network nodes (not shown) in the wireless network 100 using any suitable transport network through various types of backhaul interfaces (such as direct physical connections or virtual networks).

[0038] The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive data transmissions from an upstream station (e.g., a network node 110 or a UE 120) and transmit the data transmissions to a downstream station (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 network node, or a relay.

[0039] UE 120 may be dispersed throughout the wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a terminal, a mobile station, or a subscriber unit. UE 120 may 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, 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, or any other suitable device configured to communicate via a wireless medium.

[0040] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, or location tags, which may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices, or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included inside a housing that houses components of UE 120, such as a processor component 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, or electrically coupled.

[0041] 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 also be referred to as a radio technology or air interface. Frequency may also be referred to as a carrier or frequency channel. 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.

[0042] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more sidelink channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, or other operations described elsewhere herein as being performed by network node 110.

[0043] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, or channels by 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). Although a portion of FR1 is 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 arise in conjunction with FR2, which is often (interchangeably) referred to as the "millimeter wave" band in various documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz-300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).

[0044] 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 or FR2 characteristics, and thus the features of FR1 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.

[0045] Considering the above examples, unless otherwise specifically stated, if the term "sub-6 GHz" is used herein, it may broadly refer to frequencies that may be less than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise specifically stated, if the term "millimeter wave" is used herein, it may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a, FR4-1, 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, or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.

[0046] In some aspects, UE 120 may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may receive information configuring a periodic BWP switching pattern from the network node 110, the periodic BWP switching pattern indicating a BWP sequence, wherein each BWP in the BWP sequence is associated with a corresponding network state; and communicate with the network node 110 according to the periodic BWP switching pattern, wherein, in order to communicate with the network node 110, the communication manager 140 may sequentially switch between BWPs in the BWP sequence indicated in the periodic BWP switching pattern, wherein each BWP for communicating with the network node 110 is associated with a configuration corresponding to the corresponding network state associated with the BWP. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

[0047] In some aspects, the network node 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may send information to the UE 120 configuring a periodic BWP switching pattern, the periodic BWP switching pattern indicating a BWP sequence, wherein each BWP in the BWP sequence is associated with a corresponding network state; and communicate with the UE 120 according to the periodic BWP switching pattern, wherein, to communicate with the UE 120, the communication manager 150 may sequentially switch between the BWPs in the BWP sequence indicated in the periodic BWP switching pattern, wherein each BWP for communicating with the UE 120 is associated with a configuration corresponding to the corresponding network state associated with the BWP. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

[0048] Figure 2 200 is a diagram illustrating an example of a network node communicating with a UE in a wireless network according to the present disclosure. The network node may correspond to Figure 1 Similarly, the UE may correspond to a network node 110. Figure 1 UE 120. Network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T ≥ 1). UE 120 may be equipped with a set of antennas 252a to 252r, such as R antennas (R ≥ 1). Figure 2 The network node 110 depicted in FIG. 1 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 radio frequency components that facilitate direct communication with the UE 120, such as one or more CUs or one or more DUs.

[0049] At the network node 110, the transmit processor 220 may receive data intended for the UE 120 (or a set of UEs 120) from the 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, 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, or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, or up-convert) the output sample stream using a corresponding modulator component to obtain a downlink signal. The modems 232a to 232t may transmit a set of downlink signals (e.g., T downlink signals) via a corresponding set of antennas 234 (e.g., T antennas) (shown as antennas 234a to 234t).

[0050] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 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, 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 and / or one or more processors. 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, or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.

[0051] 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.

[0052] One or more antennas (e.g., antennas 234a to 234t or antennas 252a to 252r) may include or may be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, or one or more antenna arrays, etc. An antenna panel, antenna group, set of antenna elements, 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, or coupled to one or more transmit or receive components (such as Figure 2 One or more antenna elements of one or more components).

[0053] 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, 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, or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform aspects of any of the methods described herein.

[0054] At the network node 110, uplink signals from the UE 120 or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component of the modem 232, shown as DEMOD), detected by the MIMO detector 236 where applicable, and further processed by the receive processor 238 to obtain decoded data and control information transmitted via the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and provide 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 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, or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform aspects of any of the methods described herein.

[0055] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, or Figure 2Any other component of the UE 120 may perform one or more techniques associated with indicating network status via the BWP framework, 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, or Figure 2 Any other component of the Figure 5 The process of 500 Figure 6 600 or 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 or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of network node 110 or UE 120 (e.g., directly executed, or executed after compilation, conversion, and / or interpretation), may cause the one or more processors, UE 120, or network node 110 to perform or direct, for example, Figure 5 The process of 500 Figure 6 The operations of process 600 or other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, or interpreting instructions, etc.

[0056] In some aspects, the UE 120 includes means for receiving information configuring a periodic BWP switching pattern from the network node 110, the periodic BWP switching pattern indicating a sequence of BWPs, wherein each BWP in the sequence of BWPs is associated with a corresponding network state; and / or means for communicating with the network node 110 according to the periodic BWP switching pattern, wherein the means for communicating with the network node 110 includes: means for sequentially switching between BWPs in the sequence of BWPs indicated in the periodic BWP switching pattern, wherein each BWP for communicating with the network node 110 is associated with a configuration corresponding to the corresponding network state associated with the BWP. Means for the UE 120 to perform operations described herein may include, for example, one or more of the communication manager 140, the antenna 252, the modem 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the controller / processor 280, or the memory 282.

[0057] In some aspects, the network node 110 includes means for sending information configuring a periodic BWP switching pattern to the UE, the periodic BWP switching pattern indicating a sequence of BWPs, wherein each BWP in the sequence of BWPs is associated with a corresponding network state; and / or means for communicating with the UE 120 according to the periodic BWP switching pattern, wherein the means for communicating with the UE includes: means for sequentially switching between BWPs in the sequence of BWPs indicated in the periodic BWP switching pattern, wherein each BWP for communicating with the UE 120 is associated with a configuration corresponding to the corresponding network state associated with the BWP. Means for the network node 110 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.

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

[0059] 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 decomposed base station (e.g., a decomposed network node) may be configured to utilize a protocol stack that is 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.

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

[0061] Figure 3 300 is a diagram illustrating an example of network operation for reducing energy consumption according to the present disclosure. For various reasons, including climate change mitigation, environmental sustainability, and network cost reduction, it is expected that network energy conservation and / or network energy efficiency measures will have increasing importance in wireless network operations. For example, although NR generally provides significant energy efficiency improvements per gigabyte over previous generations (e.g., LTE), the adoption of new NR use cases and / or millimeter wave frequencies requiring high data rates may require more network sites, greater network density, more network antennas, greater bandwidth, and / or more frequency bands, which may potentially lead to more efficient wireless networks, which still have higher energy requirements and / or cause more emissions than previous generations of wireless networks. In addition, energy accounts for a large proportion of the cost of operating a wireless network. For example, according to some estimates, energy costs are about a quarter of the total cost of operating a wireless network, and more than 90% of network operating costs are spent on energy (e.g., fuel and electricity). Most of the energy consumption and / or energy costs come from powering the RAN, which accounts for about half of the energy consumed by the wireless network. Therefore, measures to increase network energy conservation and / or network energy efficiency are important factors that can drive the adoption and / or expansion of wireless networks.

[0062] One way to increase energy efficiency in the RAN may be to adapt the network energy consumption model to dynamically and / or semi-statically achieve more efficient operation. For example, power consumption in the RAN may generally be divided into a dynamic part and a static part, in which power is consumed only when data transmission and / or reception is ongoing, and in which power is always consumed to maintain the operation of the radio access equipment even when data transmission and / or reception is not ongoing. Therefore, a potential way to improve network energy saving may be to adapt the power consumption model from a network perspective by reducing the relative energy consumption of downlink and / or uplink communications (e.g., taking into account factors such as power amplifier (PA) efficiency, the number of transceiver units (TxRUs) and / or network load), enabling network sleep states and associated transition times, and / or defining appropriate reference parameters and / or configurations. For example, in some cases, different NES states may be configured to use techniques in the time domain, frequency domain, spatial domain, and / or power domain to achieve granular adaptation of transmission and / or reception to reduce energy consumption with potential support and / or feedback from the UE and / or potential UE assistance information. However, the network device and the UE may need to exchange and / or coordinate information through the network interface to control the configuration, communication parameters and / or UE behavior for each NES state, which may increase the configuration complexity and / or signaling overhead. This may pose a challenge because techniques for reducing network energy consumption should generally be designed to avoid having a significant impact on key performance indicators (KPIs) related to network and / or UE performance (e.g., spectral efficiency, latency, UE power consumption and / or complexity, etc.).

[0063] Therefore, if Figure 3 As shown, the network node may be configured to operate in different NES states 310 over time, wherein each NES state 310 may use one or more techniques to adapt transmission and / or reception in the time domain, frequency domain, spatial domain, and / or power domain. Figure 3As shown, the NES state 310 may include a normal operating mode (which may also be referred to as a legacy mode or a default mode) and one or more sleep modes that may be associated with lower power consumption than the normal operating mode. In general, a network node may transition between different NES states 310 to save power and maintain network operation (e.g., to minimize the impact on KPIs such as spectral efficiency, capacity, user perceived throughput (UPT), latency, UE power consumption, complexity, handover performance, call drop rate, initial access performance, and / or SLA guarantees). In addition, a network node may transition between different sleep modes based on business needs (e.g., entering a light sleep mode when business demand is slightly lower than usual and / or entering a deep sleep mode when business demand is much lower than usual), and different sleep modes may be associated with different energy-saving techniques (e.g., one or more antenna panels, antenna ports, and / or radio frequency (RF) chains may be turned off in a deep sleep mode but remain on in a light sleep mode). Thus, as Figure 3 As shown, the normal operating mode and different sleep modes may vary in power consumption and may be associated with different transition times (e.g., the transition time to or from a deep sleep mode may be longer than the transition time to or from a light sleep mode).

[0064] In some cases, as described herein, the NES state 310 may generally correspond to a particular set of configurations, communication parameters, and / or UE behaviors. For example, the NES state 310 may include a set of configurations, communication parameters, and / or UE behaviors associated with one or more energy-saving techniques implemented in the time domain, frequency domain, spatial domain, and / or power domain to reduce energy consumption. For example, a network node may be configured to not send synchronization signal blocks (SSBs) in a first NES state 310 (e.g., a NES state 310 without SSBs) to reduce energy consumption, and may be configured to employ other energy-saving techniques, such as shutting down one or more antenna panels in a second NES state 310. Furthermore, in some cases, the NES state 310 may be associated with a set of configurations, communication parameters, and / or UE behaviors associated with a normal or legacy network operating mode. Therefore, because one of the design goals in energy-efficient wireless networks is to achieve more efficient operation dynamically and / or semi-statically, a network node may configure a semi-static mode 320 to achieve network energy conservation. For example, as Figure 3 As shown, the semi-static mode 320 (eg, configured via radio resource control (RRC) signaling) may include a sequence of NES states 310 followed by the network node according to a given periodicity (eg, Figure 3In the embodiment of the present invention, the network node operates according to a first NES state (shown as NES1) during a first time period, then operates in a flexible mode during a second time period, then operates according to a second NES state (shown as NES2) during a third time period, and then repeats the pattern. In the case where the semi-static mode 320 includes a flexible mode, the network node may operate according to any suitable NES state (e.g., depending on current traffic conditions) during the time period corresponding to the flexible mode, and the NES state selected by the network node for the time period corresponding to the flexible mode may be dynamically indicated to the served UE.

[0065] However, in order to configure the semi-static mode 320 to switch between different NES states, the network node may need to configure each NES state for the served UE and may need to configure various parameters associated with the semi-static mode 320 (e.g., the sequence of NES states included in the semi-static mode 320 and / or the periodicity of the semi-static mode 320), which may increase configuration complexity and / or signaling overhead. Therefore, the various aspects described herein are generally related to using the BWP framework to indicate the periodic sequence of NES states. Some aspects are more specifically related to operating the network node under various NES states (e.g., default or normal mode and one or more sleep or low power modes associated with the configuration of saving power and maintaining network operation), and configuring the periodic BWP switching mode to indicate the change of the NES state of the network node at any given time. For example, in some aspects, the candidate BWP may be associated with one or more configurations, communication parameters and / or UE behaviors associated with one or more NES states, so that the periodic BWP switching mode can be used to implement switching between different NES states. For example, the network node may configure the UE with one or more candidate BWPs, and may configure the UE with a periodic BWP switching pattern to indicate a sequence of candidate BWPs and / or a sequence of configurations associated with the candidate BWPs that the network node and the UE are configured to follow when communicating on the downlink and / or uplink. In addition, each candidate BWP and / or each configuration associated with a candidate BWP in the candidate BWP sequence may be associated with a duration for which the corresponding candidate BWP and / or BWP configuration is to remain active. Thus, as referred to herein Figure 4 As described in further detail, the network node and the UE may sequentially switch between different BWPs and / or different BWP configurations according to a periodic BWP switching pattern to sequentially switch between different NES states.

[0066] Figure 4 4 is a diagram illustrating an example 400 associated with indicating a network status via a BWP framework according to the present disclosure. Figure 4As shown, example 400 includes communications between a network node (e.g., network node 110) and a UE (e.g., UE 120). In some aspects, the network node and the UE may communicate in a wireless network, such as wireless network 100. The network node and the UE may communicate via a wireless access link, which may include an uplink and a downlink.

[0067] like Figure 4 As shown, in a first operation 410, the network node may send and the UE may receive information configuring one or more BWPs and information configuring a periodic BWP switching pattern indicating a sequence of BWPs. For example, as described herein, each BWP in a sequence of BWPs may be associated with a corresponding network state corresponding to an NES state, a legacy or normal state, and / or a flexible mode, in which the corresponding network state may be dynamically configured and indicated to the UE (e.g., the flexible mode may be configured to operate according to any suitable NES state and / or legacy or normal mode, depending on the traffic conditions). For example, in some aspects, each BWP configured by the network node may be associated with one or more communication parameters corresponding to a particular NES state, or a particular BWP configured by the network node may be associated with multiple configurations that each correspond to a different NES state. Therefore, as described herein, a periodic BWP switching pattern may generally indicate a sequence of BWPs that the UE and the network node are to use to communicate via a wireless access link and the duration for which each BWP in the sequence of BWPs is to remain active. Thus, in a second operation 420, the UE and the network node may communicate according to the periodic BWP switching pattern, which may include sequentially switching between BWPs in a BWP sequence indicated in the periodic BWP switching pattern. In this way, because each BWP in the BWP switching pattern is associated with a configuration corresponding to a corresponding network state, the periodic BWP switching pattern may be used to switch between different network states without the network node having to configure different network states and / or exchange signaling with the UE to configure a semi-static pattern for switching between different network states (e.g., aspects described herein may reuse the BWP configuration and switching framework to implement configuration and switching for different network states).

[0068] For example, Figure 4An example periodic BWP switching pattern 430 is depicted that configures a UE to communicate with a network node using a first BWP (shown as BWP1) for a first duration, a second BWP (shown as BWP2) for a second duration, and a third BWP (shown as BWP3) for a third duration. As further shown, the first BWP is associated with a configuration corresponding to a first NES state (shown as NES1) (e.g., an NES state without SSB), the second BWP is associated with a configuration corresponding to a legacy or normal mode, and the third BWP is associated with a configuration corresponding to a second NES state (shown as NES2) (e.g., an NES state in which one or more RF chains are shut down). Thus, the UE and the network node can sequentially switch between different BWPs in a sequence, which can effectively implement sequential switching between different NES states and legacy or normal modes. In addition, each BWP is to maintain the corresponding duration of the active BWP (in Figure 4 , timeslots, or frames) may be indicated as an amount of a transmit time interval (e.g., an amount of symbols, time slots, or frames), or as a time period (e.g., an amount of milliseconds or seconds). For example, where the corresponding duration that each BWP is to remain an active BWP is indicated as an amount of symbols, time slots, or frames, the actual time period that each BWP remains active may vary with the subcarrier spacing, which may be different across different BWPs (e.g., symbol duration is generally proportional to subcarrier spacing, where larger subcarrier spacings have shorter symbol durations and vice versa). In this regard, an amount of N symbols, time slots, or frames may occupy a first duration in a first BWP and a second (e.g., longer or shorter) duration in a second BWP. Thus, in some cases, the duration that each BWP remains an active BWP may be indicated based on an amount of seconds or milliseconds to provide a unified time representation applicable to all BWPs in a sequence.

[0069] Additionally or alternatively, in some aspects, a fixed time unit may be defined (e.g., in terms of symbols, time slots, frames, or milliseconds / seconds), and the duration for which each BWP is to remain active may be defined by the BWP sequence and the fixed time unit. Figure 4 An example of a BWP switching sequence 440 is depicted, where each BWP is active for a duration based on a fixed unit, where Figure 4The BWP switching sequence 440 shown in can be indicated as [BWP1, BWP1, BWP2, BWP2, BWP2, BWP3, BWP3]. In this example, if the fixed time unit is configured as two (2) time slots, the first BWP (BWP1) will be active for four (4) time slots because the sequence begins with two instances of the first BWP, the second BWP (BWP2) will be active for six (6) time slots because the sequence includes three instances of the second BWP after the two instances of the first BWP, and the third BWP (BWP3) will be active for four (4) time slots because the sequence ends with two instances of the third BWP. It is worth noting that in this example, the actual time when the corresponding BWP is active can vary depending on the subcarrier spacing associated with each BWP. For example, although the first BWP and the third BWP are both active for the same amount of time slots, if the subcarrier spacing is different, the first BWP and the third BWP can be active for different durations. In another example, although the second BWP is active for a greater number of time slots than the first BWP and the third BWP, if the second BWP has a larger subcarrier spacing that translates to a shorter symbol duration than the first BWP and / or the third BWP, the second BWP may be active for a shorter time than the first BWP and / or the third BWP. In a similar aspect, if the fixed time unit is defined as an amount of milliseconds or seconds, the amount of transmit time intervals (e.g., symbols, time slots, or frames) that each BWP remains active may vary with the corresponding subcarrier spacing.

[0070] In some aspects, as described herein, a periodic BWP switching pattern may indicate a BWP sequence that may include different BWPs that are each associated with a different configuration corresponding to a different network state. However, when switching between different BWPs that may have different center frequencies and / or different bandwidths, there are typically switching delays associated with re-tuning the RF components to accommodate the new center frequency and bandwidth of the newly active BWP. However, because the periodic BWP switching pattern described herein is used to sequentially switch between different network states, some aspects described herein may associate a single BWP with multiple configurations corresponding to different network states, and the periodic BWP switching pattern may be used to sequentially switch between multiple configurations of a base BWP and thereby avoid switching delays that would otherwise be associated with re-tuning the RF components to accommodate the new center frequency and / or bandwidth. For example, Figure 4An example of a periodic BWP switching pattern 450 is depicted, in which a single base BWP is associated with different configurations corresponding to different NES states. For example, a particular BWP (shown as BWP1) may be associated with a first configuration corresponding to a first NES state (shown as NES1), a second configuration corresponding to a second NES state (shown as NES2), and a third configuration corresponding to a third NES state (shown as NES3). In general, the base BWP associated with the different configurations may be a legacy BWP (e.g., a BWP associated with a legacy or normal operating mode that may be reconfigured to implement a NES state), or the base BWP may be specifically configured for the purpose of switching between different configurations corresponding to different network states. Thus, when the UE and the network node sequentially switch between BWPs in a BWP sequence, the UE and the network node may maintain the same center frequency and bandwidth, and may only switch between different BWP configurations.

[0071] In some aspects, to configure a BWP switching pattern, a network node may send to a UE RRC signaling that configures one or more candidate BWPs and one or more configurations for each of the one or more candidate BWPs. In addition, the RRC signaling may configure a plurality of candidate BWP switching patterns, each of which includes a corresponding sequence of candidate BWPs and a corresponding duration, and each candidate BWP switching pattern may also be associated with a periodicity that defines the frequency at which the candidate BWP switching pattern repeats. In addition, in some aspects, one or more candidate BWP switching patterns may include a flexible BWP in a BWP sequence, wherein the flexible BWP is associated with a time division duplex (TDD) mode that may be dynamically indicated (e.g., in contrast to a downlink-only BWP or an uplink-only BWP). In some aspects, a flexible BWP may also be associated with a flexible mode, wherein the network node may dynamically indicate whether the flexible BWP is associated with a legacy or normal mode or with an NES state (e.g., by dynamically indicating a configuration of the flexible BWP, such as the amount of active antenna units and / or whether SSB is transmitted).

[0072] Thus, a network node may typically configure multiple candidate BWP switching modes, and one of these candidate BWP switching modes may be active at any given time. For example, after sending RRC signaling to configure the candidate BWP switching modes, the network node may send downlink control information (DCI) to indicate one of the candidate switching modes. Additionally or alternatively, the network node may send a medium access control (MAC) control element (MAC-CE) to down-select the candidate BWP switching mode configured by the RRC, and the DCI may include a field for identifying one of the candidate BWP switching modes down-selected by the MAC-CE. For example, in some aspects, each BWP switching mode configured by the network node using RRC signaling may be associated with an identifier, and the DCI may indicate an identifier associated with one of the candidate BWP switching modes that is currently active. For example, in some aspects, the DCI may include a two-bit field for indicating the BWP switching mode. However, in some cases, a two-bit field may not provide sufficient flexibility to switch between different candidate BWP switching modes (e.g., in cases where the amount of candidate BWP switching modes exceeds the amount of candidate BWP switching modes that can be indicated using two bits). In such cases, switching between different candidate BWP switching modes may be restricted (e.g., via RRC signaling) depending on the current active BWP and / or the current BWP switching mode. Additionally or alternatively, the DCI may include one or more additional bits for enabling switching between candidate BWP switching modes.
