AI Technical Summary
In a wireless communication system, when the UE switches to a new cell, it needs to reacquire the conditional configuration set, resulting in delay and excessive use of network resources.
After executing the first communication procedure, the UE may maintain the conditional configuration set associated with the possible source cell set and use these configurations in a subsequent second communication procedure to avoid the need to reacquire the configuration.
By maintaining the conditional configuration set, the UE reduces the delay associated with completing the communication procedures, reduces the utilization of network resources, and improves communication efficiency.

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS
[0002] This patent application claims priority to U.S. non-provisional patent application No. 17 / 817,214, filed on August 3, 2022, entitled “CONFIGURATION MANAGEMENT FORMULTIPLE CONFIGURATION COMMUNICATION SCENARIOS” and assigned to the assignee of this application. The disclosure of the prior application is considered a part of this patent application and is incorporated by reference into this patent application. Technical Field
[0003] Aspects of the present disclosure relate generally to wireless communications, and to techniques and apparatus for configuration management for multiple configuration communication scenarios. Background Art
[0004] Wireless communication systems are widely deployed to provide a variety of telecommunication services, such as telephony, video, data, messaging, and broadcasting. Typical wireless communication systems may employ multiple access technologies that can support communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and long term evolution (LTE). LTE / LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP).
[0005] A wireless network may include one or more network nodes that support communications for wireless communication devices, such as user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. A "downlink" (or "DL") refers to a communication link from a network node to a UE, and an "uplink" (or "UL") refers to a communication link from a UE to a network node. Some wireless networks may support device-to-device communications, such as via a local link (e.g., a side link (SL), a wireless local area network (WLAN) link, and / or a wireless personal area network (WPAN) link, etc.).
[0006] The above-mentioned multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at a city, country, region and / or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by 3GPP. NR is designed to better support mobile broadband Internet access by improving spectrum efficiency, reducing costs, improving services, utilizing new spectrum, and using orthogonal frequency division multiplexing (OFDM) with cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and / or single carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink to better integrate with other open standards, as well as supporting beamforming, multiple input multiple output (MIMO) antenna technology and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR and other radio access technologies remain useful.
[0007] Some communication systems may combine multiple generations of radio access technologies to provide network services to UEs operating therein. For example, a 5G network may include a 5G RAN and an LTE EPC, wherein the LTE EPC provides control and signaling information. Some UEs may be dual-mode UEs compatible with both non-independent network deployments and independent network deployments. When a UE operates in independent mode and fails during a random access channel (RACH) procedure on a target cell for which a conditional handover (CHO) is triggered, the UE may perform a cell selection procedure. If the selected cell is included in the CHO target cell set, the UE may perform a RACH procedure on the selected cell and apply a dedicated configuration of the selected cell. In this case, the UE may send a reconfiguration completion message and may discard the source cell configuration.
[0008] Because the conditional configuration set provided to the UE is based at least in part on the source cell configuration (e.g., the conditional configuration may be an increment relative to the source cell configuration), the UE may also discard conditional configuration sets of other possible target cells. After discarding the conditional configuration set associated with the previous source cell, the UE may be configured with a new conditional configuration set associated with the new source cell. However, obtaining a new conditional configuration set may result in a delay associated with completing the communication procedure and / or excessive use of network resources. Summary of the invention
[0009] Some aspects described herein enable a UE to maintain a set of conditional configurations. For example, the UE may execute a first communication procedure (e.g., a CHO procedure) and may maintain a set of conditional configurations associated with a set of possible source cells. In this case, the UE may use the set of conditional configurations for a second communication procedure (e.g., a recovery procedure) at a subsequent time, thereby avoiding the need to reacquire the conditional configurations for the second communication procedure.
[0010] Some aspects described herein relate to a method of wireless communication performed by a user equipment (UE). The method may include receiving information from a network node identifying a set of conditional configurations for a set of possible target cells associated with a first communication procedure, wherein the set of conditional configurations is associated with a primary cell group or a secondary cell group. The method may include communicating with the network node or another network node according to a conditional configuration in the set of conditional configurations associated with a second communication procedure.
[0011] Some aspects described herein relate to a UE for wireless communication. The UE may include a memory and one or more processors coupled to the memory. The one or more processors may be configured to receive information from a network node identifying a conditional configuration set for a possible target cell set associated with a first communication procedure, wherein the conditional configuration set is associated with a primary cell group or a secondary cell group. The one or more processors may be configured to communicate with the network node or another network node according to a conditional configuration associated with a second communication procedure in the conditional configuration set.
[0012] Some aspects described herein relate to a non-transitory computer-readable medium storing an instruction set for wireless communication by a UE. The instruction set, when executed by one or more processors of the UE, may cause the UE to receive information identifying a conditional configuration set for a set of possible target cells associated with a first communication procedure from a network node, wherein the conditional configuration set is associated with a primary cell group or a secondary cell group. The instruction set, when executed by one or more processors of the UE, may cause the UE to communicate with the network node or another network node according to a conditional configuration associated with a second communication procedure in the conditional configuration set.
[0013] Some aspects described herein relate to an apparatus for wireless communication. The apparatus may include means for receiving information identifying a set of conditional configurations for a set of possible target cells associated with a first communication procedure from a network node, wherein the set of conditional configurations is associated with a primary cell group or a secondary cell group. The apparatus may include means for communicating with the network node or another network node according to a conditional configuration in the set of conditional configurations associated with a second communication procedure.
[0014] The various aspects generally include methods, apparatus, systems, computer program products, non-transitory computer-readable media, user equipment, base stations, network entities, network nodes, wireless communication devices and / or processing systems as fully described herein with reference to the drawings and description and as illustrated in the drawings and description.

[0025] 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 protection scope of the present disclosure will be fully conveyed to those skilled in the art. It should 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, any number of aspects set forth herein may be used to implement a device or practice method. In addition, the scope of the present disclosure is intended to cover such devices or methods implemented using other structures, functionality, or structures and functionality in addition to or different from the various aspects of the disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the present claim.
[0026] Several aspects of telecommunication systems will now be presented with reference to various devices and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements can be implemented using hardware, software, or a combination thereof. Whether these elements are implemented as hardware or software depends on the specific application and the design constraints imposed on the overall system.
[0027] Although various aspects may be described herein using terms generally associated with 5G or new radio (NR) radio access technology (RAT), various aspects of the present disclosure may be applied to other RATs, such as 3G RAT, 4G RAT and / or RATs beyond 5G (e.g., 6G).
[0028] Figure 1 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be a 5G (e.g., NR) network and / or a 4G (e.g., Long Term Evolution (LTE)) network, or may include elements of a 5G (e.g., NR) network and / or elements of a 4G (e.g., Long Term Evolution (LTE)) network, etc. The wireless network 100 may include one or more network nodes 110 (shown as network node 110a, network node 110b, network node 110c, and network node 110d), user equipment (UE) 120 or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120e), and / or other entities. The network node 110 is a network node that communicates with the UE 120. As shown in the figure, the network node 110 may include one or more network nodes. For example, the network node 110 may be a converged network node, which means that the converged network node is configured to utilize a radio protocol stack that is physically or logically integrated within a single radio access network (RAN) node (e.g., within a single device or unit). For 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)).
[0029] In some examples, the network node 110 is or includes a network node (such as an RU) that communicates with the UE 120 via a radio access link. In some examples, the network node 110 is or includes a network node (such as a DU) that communicates with other network nodes 110 via a fronthaul link or a midhaul link. In some examples, the network node 110 is or includes a network node (such as a CU) that communicates with other network nodes 110 via a midhaul link or communicates with a core network via a backhaul link. In some examples, the network node 110 (such as an aggregated network node 110 or a decomposed network node 110) may include multiple network nodes, such as one or more RUs, one or more CUs, and / or one or more DUs. For example, the network node 110 may include an NR base station, an LTE base station, a Node B, an eNB (e.g., in 4G), a gNB (e.g., in 5G), an access point, a transmit receive point (TRP), a DU, a RU, a CU, a mobility element of a network, a core network node, a network element, a network equipment, a RAN node, or a combination thereof. In some examples, network nodes 110 may be interconnected to each other or to one or more other network nodes 110 in wireless network 100 via various types of fronthaul interfaces, midhaul interfaces, and / or backhaul interfaces (such as direct physical connections, air interfaces, or virtual networks) using any suitable transport network.
[0030] In some examples, the network node 110 may provide communication coverage for a particular geographic area. In the Third Generation Partnership Project (3GPP), the term "cell" may refer to the coverage area of the network node 110 and / or the network node subsystem serving the coverage area, depending on the context in which the term is used. The network node 110 may provide communication coverage for a macro cell, a pico cell, a femto cell, and / or another type of cell. A macro cell may cover a relatively large geographic area (e.g., a radius of several kilometers) and may allow unrestricted access by a UE 120 with a service subscription. A pico cell may cover a relatively small geographic area and may allow unrestricted access by a UE 120 with a service subscription. A femto cell may cover a relatively small geographic area (e.g., a home) and may allow restricted access by a UE 120 associated with the femto cell (e.g., a UE 120 in a closed subscriber group (CSG)). A network node 110 for a macro cell may be referred to as a macro network node. A network node 110 for a pico cell may be referred to as a pico network node. The network node 110 for a femto cell may be referred to as a femto network node or a home network node. Figure 1In the example shown, network node 110a may be a macro network node for macro cell 102a, network node 110b may be a pico network node for pico cell 102b, and network node 110c may be a femto network node for femto cell 102c. 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).
[0031] In some aspects, the term "base station" or "network node" may refer to an aggregated base station, a decomposed base station, an integrated access and backhaul (IAB) node, a relay node, or one or more components thereof. For example, in some aspects, a "base station" or "network node" may refer to a CU, a DU, a RU, a near real-time (near RT) RAN intelligent controller (RIC), or a non-real-time (non-RT) RIC, or a combination thereof. In some aspects, the term "base station" or "network node" may refer to a device configured to perform one or more functions (such as those described herein in conjunction with the network node 110). In some aspects, the term "base station" or "network node" may refer to a plurality of devices configured to perform one or more functions. For example, in some distributed systems, each of a number of different devices (which may be located in the same geographic location or in different geographic locations) may be configured to perform at least a portion of a function, or to repeat the execution of at least a portion of the function, and the term "base station" or "network node" may refer to any one or more of these different devices. In some aspects, the term "base station" or "network node" may refer to one or more virtual base stations or one or more virtual base station functions. For example, in some aspects, two or more base station functions may be instantiated on a single device. In some aspects, the term "base station" or "network node" may refer to one of the base station functions but not another base station function. In this way, a single device may include more than one base station.
[0032] The wireless network 100 may include one or more relay stations. A relay station is a network node that can receive transmissions of data from an upstream node (e.g., a network node 110 or a UE 120) and transmit transmissions of data to a downstream node (e.g., a UE 120 or a network node 110). A relay station may be a UE 120 that can relay transmissions for other UEs 120. Figure 1 In the example shown, a network node 110d (e.g., a relay network node) may communicate with a network node 110a (e.g., a macro network node) and a UE 120d to facilitate communications between the network node 110a and the UE 120d. A network node 110 that relays communications may be referred to as a relay station, a relay base station, a relay network node, a relay node, a relay, etc.
[0033] The wireless network 100 may be a heterogeneous network that includes different types of network nodes 110, such as macro network nodes, pico network nodes, femto network nodes, relay network nodes, etc. These different types of network nodes 110 may have different transmit power levels, different coverage areas, and / or different impacts on interference in the wireless network 100. For example, a macro network node may have a high transmit power level (e.g., 5 watts to 40 watts), while a pico network node, a femto network node, and a relay network node may have a lower transmit power level (e.g., 0.1 watt to 2 watts).
[0034] The network controller 130 may be coupled to or in communication with a set of network nodes 110 and may provide coordination and control for the network nodes 110. The network controller 130 may communicate with the network nodes 110 via a backhaul communication link or a midhaul communication link. The network nodes 110 may also communicate directly with each other or indirectly via a wireless backhaul communication link or a wired backhaul communication link. In some aspects, the network controller 130 may be or may include a CU or a core network device.
[0035] 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, and / 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, and / or a satellite radio), a vehicle component or sensor, a smart meter / sensor, an industrial manufacturing equipment, a global positioning system device, a UE function of a network node, and / or any other suitable device configured to communicate via a wireless or wired medium.
[0036] Some UEs 120 may be considered as machine type communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and / or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors and / or location tags, which may communicate with a network node, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered as Internet of Things (IoT) devices and / or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered as customer premises equipment. UE 120 may be included in a housing that houses components of UE 120, such as a processor component and / or a memory component. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., a memory) may be operationally coupled, communicatively coupled, electronically coupled, and / or electrically coupled.
[0037] Generally speaking, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a specific RAT and may operate on one or more frequencies. RAT may be referred to as a radio technology, air interface, etc. Frequency may be referred to as a carrier, frequency channel, etc. Each frequency may support a single RAT in a given geographic area to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.
[0038] In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120e) may communicate directly using one or more side link channels (e.g., without using network node 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, vehicle-to-everything (V2X) protocols (e.g., which may include vehicle-to-vehicle (V2V) protocols, vehicle-to-infrastructure (V2I) protocols, or vehicle-to-pedestrian (V2P) protocols), and / or mesh networks. In such examples, UE 120 may perform scheduling operations, resource selection operations, and / or other operations described elsewhere herein as being performed by network node 110.
[0039] The devices of the wireless network 100 may communicate using an electromagnetic spectrum, which may be subdivided into various categories, bands, channels, etc., according to frequency or wavelength. For example, the devices of the wireless network 100 may communicate using one or more operating bands. In 5G NR, two initial operating bands have been identified as frequency ranges designated FR1 (410 MHz to 7.125 GHz) and FR2 (24.25 GHz to 52.6 GHz). It should be understood that 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. A similar naming problem sometimes occurs with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the extremely high frequency (EHF) band (30 GHz to 300 GHz) identified as the "millimeter wave" band by the International Telecommunication Union (ITU).
[0040] 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 to 24.25GHz). The bands falling within FR3 can inherit FR1 characteristics and / or FR2 characteristics, and therefore the features of FR1 and / or FR2 can be effectively extended to mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operations to more than 52.6GHz. For example, three higher operating bands have been identified as frequency range designations FR4a or FR4-1 (52.6GHz to 71GHz), FR4 (52.6GHz to 114.25GHz) and FR5 (114.25GHz to 300GHz). Each of these higher frequency bands falls within the EHF band.
[0041] Considering the above examples, unless otherwise explicitly stated, it should be understood that if the term "below 6 GHz" or the like is used herein, the term may broadly refer to frequencies that may be lower than 6 GHz, may be within FR1, or may include mid-band frequencies. In addition, unless otherwise explicitly stated, it should be understood that if the term "millimeter wave" or the like is used herein, the term may broadly refer to frequencies that may include mid-band frequencies, may be within FR2, FR4, FR4-a or FR4-1, and / or FR5, or may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4, FR4-a, FR4-1, and / or FR5) may be modified, and the techniques described herein are applicable to those modified frequency ranges.
[0042] 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 identifying a conditional configuration set for a set of possible target cells associated with a first communication procedure from a network node, wherein the conditional configuration set is associated with a primary cell group or a secondary cell group; and communicate with the network node or another network node according to a conditional configuration in the conditional configuration set associated with a second communication procedure. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.
[0043] As indicated above, Figure 1 are provided as examples. Other examples can be found in the Figure 1 The examples described are different.
[0044] Figure 2 2 is a diagram illustrating an example 200 of a network node 110 communicating with a UE 120 in a wireless network 100 according to the present disclosure. The network node 110 may be equipped with a set of antennas 234a to 234t, such as T antennas (T≥1). The UE 12 may be equipped with a set of antennas 252a to 252r, such as R antennas (R≥1). The network node 110 of example 200 includes one or more radio frequency components, such as an antenna 234 and a modem 254. In some examples, the network node 110 may include an interface, a communication component, or another component that facilitates communication with the UE 120 or another network node. Some network nodes 110 may not include a radio frequency component that facilitates direct communication with the UE 120, such as one or more CUs or one or more DUs.
[0045] 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 (CQI) 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 provide data symbols for the UE 120. The transmit processor 220 may process system information (e.g., for semi-static resource partitioning information (SRPI)) and control information (e.g., CQI requests, grants, and / or upper layer signaling), and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary synchronization signals (PSS) or secondary synchronization signals (SSS)). The transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., pre-decoding) on data symbols, control symbols, overhead symbols, and / or reference symbols, where applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems) (shown as modems 232a to 232t). For example, each output symbol stream may be provided to a modulator component (shown as MOD) of the modem 232. Each modem 232 may process a corresponding output symbol stream (e.g., for OFDM) using a corresponding modulator component to obtain an output sample stream. Each modem 232 may further process (e.g., convert to analog, amplify, filter, and / 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).
[0046] At the UE 120, a set of antennas 252 (shown as antennas 252a to 252r) may receive downlink signals from the network node 110 and / or other network nodes 110 and may provide a set of received signals (e.g., R received signals) to a set of modems 254 (e.g., R modems) (shown as modems 254a to 254r). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of the modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and / or digitize) the received signal to obtain input samples. Each modem 254 may use a demodulator component to further process the input samples (e.g., for OFDM) to obtain received symbols. A MIMO detector 256 may obtain received symbols from the modem 254, may perform MIMO detection on the received symbols where applicable, and may provide detected symbols. The receive processor 258 may process (e.g., demodulate and decode) detected symbols, may provide decoded data for the UE 120 to the data sink 260, and may provide decoded control information and system information to the controller / processor 280. The term "controller / processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a reference signal received power (RSRP) parameter, a received signal strength indicator (RSSI) parameter, a reference signal received quality (RSRQ) parameter, and / or a CQI parameter, among other things. In some examples, one or more components of the UE 120 may be included in the housing 284.
[0047] 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.
[0048] One or more antennas (e.g., antennas 234a to 234t and / or antennas 252a to 252r) may include or be included within one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and / or one or more antenna arrays, etc. Antenna panels, antenna groups, sets of antenna elements, and / or antenna arrays may include one or more antenna elements (in a single housing or multiple housings), sets of coplanar antenna elements, sets of non-coplanar antenna elements, and / or coupled to one or more transmit and / or receive components (such as, Figure 2 One or more antenna elements of one or more components in.
[0049] On the uplink, at the UE 120, the transmit processor 264 may receive and process data from the data source 262 and control information from the controller / processor 280 (e.g., for reports including RSRP, RSSI, RSRQ, and / or CQI). The transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from the transmit processor 264 may be pre-decoded by the TX MIMO processor 266, where applicable, further processed by the modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to the network node 110. In some examples, the modem 254 of the UE 120 may include a modulator and a demodulator. In some examples, the UE 120 includes a transceiver. The transceiver may include any combination of an antenna 252, a modem 254, a MIMO detector 256, a receive processor 258, a transmit processor 264, and / or a TX MIMO processor 266. The transceiver may be used by a processor (eg, controller / processor 280) and memory 282 to perform the functions described herein (eg, with reference to Figures 5 to 7 )Aspects of any of the methods described herein.
[0050] At the network node 110, uplink signals from the UE 120 and / or other UEs may be received by the antenna 234, processed by the modem 232 (e.g., a demodulator component 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 by the UE 120. The receive processor 238 may provide the decoded data to the data sink 239 and the decoded control information to the controller / processor 240. The network node 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. The network node 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and / or uplink communications. In some examples, the modem 232 of the network node 110 may include a modulator and a demodulator. In some examples, the network node 110 includes a transceiver. The transceiver may include any combination of antenna 234, modem 232, MIMO detector 236, receive processor 238, transmit processor 220, and / or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller / processor 240) and memory 242 to perform operations described herein (e.g., with reference to Figures 5 to 7 )Aspects of any of the methods described herein.
[0051] The controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other components of the network node 110 may perform one or more techniques associated with fault handling for multiple configuration communication scenarios, as described in more detail elsewhere herein. For example, the controller / processor 240 of the network node 110, the controller / processor 280 of the UE 120, and / or Figure 2 Any other component of the Figure 6 10 and / or operations of process 600 and / 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 and / or memory 282 may include a non-transitory computer-readable medium that stores one or more instructions (e.g., code and / or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of network node 110 and / or UE 120 (e.g., directly, or after compilation, conversion, and / or interpretation), may cause the one or more processors, UE 120, and / or network node 110 to perform or direct, for example, Figure 6 The process 600 and / or operations of other processes as described herein. In some examples, executing instructions may include running instructions, converting instructions, compiling instructions, and / or interpreting instructions, etc.
[0052] In some aspects, the UE 120 includes a component for receiving information identifying a conditional configuration set for a set of possible target cells associated with a first communication procedure from a network node, wherein the conditional configuration set is associated with a primary cell group or a secondary cell group; and / or a component for communicating with the network node or another network node according to a conditional configuration in the conditional configuration set associated with a second communication procedure. The components for the UE 120 to perform the 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.
[0053] Although Figure 2 The blocks in the 200 and 210 are illustrated as distinct components, but the functionality described above for these blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functionality described for 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.
[0054] As indicated above, Figure 2 are provided as examples. Other examples can be found in the Figure 2 The examples described are different.
[0055] The deployment of a communication system (such as a 5G NR system) can be arranged with various components or components in a variety of ways. In a 5G NR system or network, a network node, a network entity, a mobility element of a network, a RAN node, a core network node, a network element, a base station or network equipment can be implemented in an aggregated or decomposed architecture. For example, a base station (such as a node B (NB), an evolved NB (eNB), an NR BS, a 5G NB, an access point (AP), a TRP or a cell, etc.) or one or more units (or one or more components) that perform base station functionality can be implemented as an aggregated base station (also referred to as an independent base station or a monolithic base station) or a decomposed base station. "Network entity" or "network node" may refer to a decomposed base station or one or more units of a decomposed base station (such as one or more CUs, one or more DUs, one or more RUs, or a combination thereof).
[0056] 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.
[0057] Base station type operations or network designs may take into account the aggregated nature of base station functionality. For example, a decomposed base station may be utilized in an IAB network, an open radio access network (O-RAN (such as a network configuration initiated by the O-RAN Alliance)), or a virtualized radio access network (vRAN, also known as a cloud radio access network (C-RAN)) to facilitate the scaling of a communication system by separating base station functionality into one or more units that can be deployed separately. A decomposed base station may include functionality implemented across two or more units at various physical locations, as well as functionality implemented virtually for at least one unit, which may enable flexibility in network design. Individual units of a decomposed base station may be configured for wired or wireless communication with at least one other unit of the decomposed base station.
[0058] Figure 33 is a diagram illustrating an example disaggregated base station architecture 300 according to the present disclosure. The disaggregated base station architecture 300 may include a CU 310, which may communicate directly with a core network 320 via a backhaul link, or indirectly with the core network 320 through one or more disaggregated control units (such as a near-RT RIC 325 via an E2 link, or a non-RT RIC 315 associated with a service management and orchestration (SMO) framework 305, or both). The CU 310 may communicate with one or more DUs 330 via respective midhaul links, such as via an F1 interface. Each of the DUs 330 may communicate with one or more RUs 340 via respective fronthaul links. Each of the RUs 340 may communicate with one or more UEs 120 via respective radio frequency (RF) access links. In some implementations, a UE 120 may be served simultaneously by multiple RUs 340.
[0059] Each of the units (including CU 310, DU 330, RU 340) and the near-RT RIC 325, non-RT RIC 315, and SMO framework 305 may include or be coupled to one or more interfaces configured to receive or send signals, data, or information (collectively referred to as signals) via a wired or wireless transmission medium. Each of the units or an associated processor or controller that provides instructions to one or more communication interfaces of the corresponding unit may be configured to communicate with one or more of the other units via a transmission medium. In some examples, each of these units may include a wired interface and a wireless interface, the wired interface being configured to receive signals or send signals to one or more of the other units via a wired transmission medium, and the wireless interface may include a receiver, a transmitter, or a transceiver (such as an RF transceiver), which is configured to receive signals or send signals to one or more of the other units via a wireless transmission medium, or both.
[0060] In some aspects, the CU 310 may host one or more higher layer control functions. Such control functions may include radio resource control (RRC) functions, packet data convergence protocol (PDCP) functions, or service data adaptation protocol (SDAP) functions, etc. Each control function may be implemented using an interface that is configured to communicate signals with other control functions hosted by the CU 310. The CU 310 may be configured to handle user plane functionality (e.g., central unit-user plane (CU-UP) functionality), control plane functionality (e.g., central unit-control plane (CU-CP) functionality), or a combination thereof. In some specific implementations, the CU 310 may be logically split into one or more CU-UP units and one or more CU-CP units. When implemented in an O-RAN configuration, the CU-UP unit may communicate bidirectionally with the CU-CP unit via an interface such as an E1 interface. As needed, the CU 310 may be implemented to communicate with the DU 330 for network control and signaling.
[0061] Each DU 330 may correspond to a logical unit that includes one or more base station functions for controlling the operation of one or more RUs 340. In some aspects, the DU 330 may host one or more of a radio link control (RLC) layer, a MAC layer, and one or more high physical (PHY) layers, at least in part, according to a functional partition such as that defined by 3GPP. In some aspects, one or more high PHY layers may be implemented by one or more modules for forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, etc. In some aspects, the DU 330 may also host one or more low PHY layers, such as one or more modules for fast Fourier transform (FFT), inverse FFT (iFFT), digital beamforming or physical random access channel (PRACH) extraction and filtering, etc. Each layer (which may also be referred to as a module) may be implemented using an interface that is configured to communicate signals with other layers (and modules) hosted by the DU 330 or with control functions hosted by the CU 310.
[0062] Each RU 340 may implement lower layer functionality. In some deployments, the RU 340 controlled by the DU 330 may correspond to a logical node that hosts RF processing functions based on functional partitioning (e.g., functional partitioning defined by 3GPP) such as lower layer functional partitioning, or low PHY layer functions such as performing FFT, performing iFFT, digital beamforming, or PRACH extraction and filtering, etc. In such an architecture, each RU 340 may be operated to handle over-the-air (OTA) communications with one or more UEs 120. In some specific implementations, real-time and non-real-time aspects of communicating with the control and user planes of the RU 340 may be controlled by the corresponding DU 330. In some scenarios, this configuration may enable each DU 330 and CU 310 to be implemented in a cloud-based RAN architecture such as a vRAN architecture.
[0063] The SMO framework 305 may be configured to support RAN deployment and provisioning of non-virtualized network elements and virtualized network elements. For non-virtualized network elements, the SMO framework 305 may be configured to support the deployment of dedicated physical resources for RAN coverage requirements, which may be managed via an operation and maintenance interface (such as an O1 interface). For virtualized network elements, the SMO framework 305 may be configured to interact with a cloud computing platform (such as an open cloud (O-Cloud) platform 390) to perform network element lifecycle management (such as instantiating virtualized network elements) via a cloud computing platform interface (such as an O2 interface). Such virtualized network elements may include, but are not limited to, CU 310, DU 330, RU 340, non-RT RIC 315, and near-RT RIC 325. In some specific implementations, the SMO framework 305 may communicate with hardware aspects of the 4G RAN (such as an open eNB (O-eNB) 311) via the O1 interface. Additionally, in some implementations, the SMO framework 305 can communicate directly with each of the one or more RUs 340 via a corresponding O1 interface. The SMO framework 305 can also include a non-RT RIC 315 configured to support the functionality of the SMO framework 305.
[0064] The non-RT RIC 315 may be configured to include logic functions that enable non-real-time control and optimization of RAN elements and resources, artificial intelligence / machine learning (AI / ML) workflows including model training and updating, or policy-based guidance of applications / features in the near-RT RIC 325. The non-RT RIC 315 may be coupled to or in communication with the near-RT RIC 325 (such as via an A1 interface). The near-RT RIC 325 may be configured to include logic functions that enable near-real-time control and optimization of RAN elements and resources via data collection and actions through an interface (such as via an E2 interface) that connects one or more CUs 310, one or more DUs 330, or both, and the O-eNB with the near-RT RIC 325.
[0065] In some implementations, in order to generate an AI / ML model to be deployed in the near-RT RIC 325, the non-RT RIC 315 may receive parameters or external enrichment information from an external server. Such information may be utilized by the near-RT RIC 325 and may be received from a non-network data source or from a network function at the SMO framework 305 or the non-RT RIC 315. In some examples, the non-RT RIC 315 or the near-RT RIC 325 may be configured to tune RAN behavior or performance. For example, the non-RT RIC 315 may monitor long-term trends and patterns of performance and employ AI / ML models to perform corrective actions through the SMO framework 305 (such as via reconfiguration of the O1 interface) or via the creation of RAN management policies (such as A1 interface policies).
[0066] As indicated above, Figure 3 are provided as examples. Other examples can be found in the Figure 3 The examples described are different.
[0067] Figure 4 is a diagram illustrating an example 400 of dual connectivity according to the present disclosure. Figure 4The example shown is for Evolved Universal Mobile Telecommunications System Terrestrial Radio Access (E-UTRA)-NR Dual Connectivity (ENDC) mode. In ENDC mode, UE 120 communicates using LTE RAT on a primary cell group (MCG), and UE 120 communicates using NR RAT on a secondary cell group (SCG). Some other modes include NR-E-UTRA Dual Connectivity (NEDC) mode (e.g., where the MCG is associated with the NR RAT and the SCG is associated with the LTE RAT), NR Dual Connectivity (NRDC) mode (e.g., where the MCG is associated with the NR RAT and the SCG is also associated with the NR RAT), or another dual connectivity mode (e.g., where the MCG is associated with the first RAT and the SCG is associated with one of the first RAT or the second RAT). ENDC mode is sometimes referred to as NR or 5G non-standalone (NSA) mode. Therefore, as used herein, "dual connectivity mode" may refer to ENDC mode, NEDC mode, NRDC mode, and / or another type of dual connectivity mode.
[0068] like Figure 4 As shown, UE 120 may communicate with both eNB 452 (e.g., 4G network node 110) and gNB 454 (e.g., 5G network node 110), and eNB 452 and gNB 454 may communicate with a 4G / LTE core network (shown as an evolved packet core (EPC) including a mobility management entity (MME), a packet data network gateway (PGW), a serving gateway (SGW), and / or other devices) (e.g., directly or indirectly). Figure 4 In some aspects, the eNB 452 and the gNB 454 may be co-located at the same network node 110. In some aspects, the eNB 452 and the gNB 454 may be included in different base stations 110 (e.g., they may not be co-located).
[0069] like Figure 4As further shown, in some aspects, a wireless network that allows operation in 5G NSA mode may allow such operation using a primary cell group (MCG) for a first RAT (e.g., LTE RAT or 4G RAT) and a secondary cell group (SCG) for a second RAT (e.g., NR RAT or 5G RAT). In this case, the UE 120 may communicate with the eNB 452 via the MCG and may communicate with the gNB 454 via the SCG. In some aspects, the MCG may anchor the network connection between the UE 120 and the 4G / LTE core network (e.g., for mobility, coverage, and / or control plane information), and the SCG may be added as an additional carrier to increase throughput (e.g., for data services and / or user plane information). In some aspects, the gNB 454 and the eNB 452 may not pass user plane information between each other. In some aspects, a UE 120 operating in dual connectivity mode may be concurrently connected to an LTE network node 110 (e.g., an eNB 452) and an NR network node 110 (e.g., a gNB 454) (e.g., in the case of ENDC or NEDC), or may be concurrently connected to one or more base stations 110 using the same RAT (e.g., in the case of NRDC). In some aspects, an MCG may be associated with a first frequency band (e.g., a sub-6 GHz band and / or a FR1 band), and an SCG may be associated with a second frequency band (e.g., a mmWave band and / or a FR2 band).
[0070] UE 120 may communicate via MCG and SCG using one or more radio bearers (e.g., data radio bearers (DRBs) and / or signaling radio bearers (SRBs)). For example, UE 120 may send or receive data via the MCG and / or SCG using one or more DRBs. Similarly, UE 120 may send or receive control information (e.g., radio resource control (RRC) information and / or measurement reports) using one or more SRBs. In some aspects, a radio bearer may be dedicated to a specific cell group (e.g., a radio bearer may be an MCG bearer or an SCG bearer). In some aspects, a radio bearer may be a split radio bearer. Split radio bearers may be split in the uplink and / or downlink. For example, a DRB may be split on the downlink (e.g., UE 120 may receive downlink information for an MCG or SCG in a DRB) but not split on the uplink (e.g., an uplink may not be split from a primary path to an MCG or SCG such that UE 120 transmits in the uplink only on the primary path). In some aspects, the DRB may be split on the uplink from the primary path to the MCG or SCG. The DRB split in the uplink may use the primary path to send data until the size of the uplink transmit buffer meets the uplink data split threshold. If the uplink transmit buffer meets the uplink data split threshold, the UE 120 may use the DRB to send data to the MCG or SCG.
[0071] As indicated above, Figure 4 are provided as examples. Other examples can be found in the Figure 4 The examples described are different.
[0072] As described above, some communication systems may combine multiple generations of radio access technologies to provide network services to UEs operating therein. For example, a 5G network may include a 5G RAN and an LTE EPC, wherein the LTE EPC provides control and signaling information. The communication system may utilize a 4G network associated with the LTE EPC to provide faster and more reliable enhanced mobile broadband (eMBB) without providing a completely new core network technology or requiring customers to switch to a 5G UE. Such deployments may be referred to as "non-standalone" 5G deployments. In contrast, "standalone" 5G deployments may use a 5G core network associated with a service-based architecture (SBA) to provide control and signaling information instead of an LTE EPC. Some UEs may be dual-mode UEs compatible with both non-standalone network deployments and standalone network deployments. In such cases, the UE may switch between standalone mode and non-standalone mode based at least in part on which network deployment the UE is using for communication services.
[0073] When a failure occurs during a random access channel (RACH) procedure on a target cell for which a conditional handover (CHO) is triggered (e.g., when the UE is operating in standalone mode), the UE may perform a cell selection procedure. If the selected cell is included in the CHO target cell set, the UE may perform a RACH procedure on the selected cell and apply a dedicated configuration of the selected cell. In this case, the UE may send a reconfiguration complete message and may discard the source cell configuration. Because the conditional configuration set provided to the UE is at least partially based on the source cell configuration (e.g., the conditional configuration may be an increment relative to the source cell configuration), the UE may also discard the conditional configuration set of other possible target cells. Similarly, if the selected cell is not included in the CHO target cell set, the UE may discard the source cell configuration and the conditional configuration of other possible target cells and perform an RRC reconstruction procedure on the selected cell using a default configuration (which may be defined in the specification). In this case, the UE is reconfigured via an RRC reconfiguration message sent after the RRC reconstruction procedure is successful. Additional details on conditional configuration (also referred to as MCG configuration and configured using the CondReconfigToAddModList-r16 message) can be found in 3GPP Technical Specification (TS) 38.331.
[0074] After discarding the conditional configuration set associated with the previous source cell, the UE may be configured using a new conditional configuration set associated with the new source cell. However, obtaining a new conditional configuration set may result in delays associated with completing a communication procedure and / or excessive use of network resources. Therefore, in some cases, the UE may receive configuration information from a network node that identifies an MCG configuration group associated with a conditional configuration set associated with a set of possible target cells. In this case, the conditional configuration configured for the UE is associated not only with a single source cell that the UE is using, but also with a set of possible target cells that the UE can use. However, the UE may still discard the conditional configuration during the communication procedure.
[0075] Some aspects described herein enable a UE to maintain a set of conditional configurations. For example, the UE may execute a first communication procedure (e.g., a CHO procedure) and may maintain a set of conditional configurations associated with a set of possible source cells and received in conjunction with an MCG configuration group (e.g., an MCG configuration or an SCG configuration). In this case, the UE may use the set of conditional configurations for a second communication procedure (e.g., a recovery procedure) at a subsequent time, thereby avoiding the need to reacquire the conditional configurations for the second communication procedure. Based at least in part on maintaining the set of conditional configurations, the UE reduces latency associated with completing a communication procedure and / or utilization of network resources associated with configuring the UE.
[0076] Figure 5is a diagram illustrating an example 500 associated with troubleshooting for multiple configuration communication scenarios according to the present disclosure. Figure 5 As shown, example 500 includes communications between network node 110 and UE 120 .
[0077] As in Figure 5 , and as further shown by reference numeral 510, UE 120 may receive information identifying a conditional configuration set. For example, UE 120 may receive a conditional configuration set (e.g., an MCG configuration or an SCG configuration) associated with a CHO procedure. UE 120 may receive the conditional configuration set from network node 110. In some aspects, UE 120 may operate in a standalone mode. In some aspects, UE 120 may be triggered to perform a recovery procedure. For example, when a failure occurs during a RACH procedure on a target cell for which CHO is triggered, as described herein, UE 120 may be triggered to perform a recovery procedure using multiple MCG configurations. In some aspects, UE 120 may receive multiple SCG configurations. For example, in conjunction with a conditional primary and secondary cell (PSCell) addition (CPA) procedure or a conditional PSCell change (CPC) procedure, UE 120 may receive an SCG configuration set.
[0078] In some aspects, UE 120 may receive an indication of whether to maintain a conditional configuration set (e.g., an MCG configuration set or an SCG configuration set) after completing a first communication procedure (e.g., from network node 110), as described herein. For example, network node 110 may send a message including an indicator that UE 120 is to maintain the conditional configuration set after completing the first communication procedure. In this case, UE 120 may maintain the conditional configuration set and may use the conditional configuration set for a subsequent second communication procedure, as described herein. In this way, UE 120 and network node 110 reduce the latency associated with obtaining the conditional configuration set for the second communication procedure (e.g., by maintaining the conditional configuration set rather than discarding the conditional configuration set in conjunction with the first communication procedure). In contrast, when UE 120 receives an indicator that the conditional configuration set is not to be maintained, UE 120 may discard the conditional configuration set during or after completing the first communication procedure.
[0079] As in Figure 5, and as further shown by reference numerals 520, 530, and 540, UE 120 may communicate with one or more network nodes 110 to complete a first communication procedure, maintain a set of condition configurations, and use the condition configurations in the set of condition configurations for a second communication procedure. A communication procedure may include multiple messages or steps (e.g., signal exchanges) or a single message or step (e.g., a single transmission or reception of a signal), which may or may not occur within a larger procedure. In other words, the first communication procedure described herein may be a first set of steps, and the second communication procedure described herein may be a second set of steps independent of the first set of steps. Alternatively, the first communication procedure may be a first step and the second communication procedure may be a second step, wherein the first step and the second step include all or part of some other communication procedure.
[0080] In some aspects, the UE 120 may detect a handover failure in the first communication procedure and perform a second communication procedure to recover from the handover failure of the first communication procedure. For example, the UE 120 may perform a recovery procedure on the selected target cell, and the recovery procedure may include a cell selection procedure, a RACH procedure, and / or a conditional handover. The UE 120 may detect a RACH failure associated with the RACH procedure and may perform a cell selection procedure as part of the recovery procedure. In this case, if the selected cell is included in the possible CHO target cell set to which the conditional configuration set is applicable, the UE 120 may maintain the conditional configuration set after completing the first communication procedure, as described herein. Alternatively, if the selected cell is not included in the possible CHO target cell set to which the conditional configuration set is applicable, the UE 120 may discard the conditional configuration set (and the source cell configuration). During the recovery procedure, the UE 120 may apply the selected cell-specific configuration to the selected cell. The selected cell-specific configuration may be based at least in part on the source cell-specific configuration of the source cell of the UE before the RACH procedure. For example, UE 120 may apply an offset value or an increment value to the source cell-specific configuration.
[0081] In some aspects, UE 120 may initiate an RRC reestablishment procedure not based, at least in part, on a handover failure. For example, UE 120 may detect an MCG radio link failure (RLF) and may initiate an RRC reestablishment. In this case, UE 120 may select a cell for RRC reestablishment and may maintain a conditional configuration set based, at least in part, on selecting the cell. For example, UE 120 may send an RRC reestablishment request and may receive an RRC reestablishment message (e.g., a first communication procedure) with an indication of maintaining a conditional configuration set. In this case, UE 120 may apply a conditional configuration in the conditional configuration set to the selected cell and send an RRC reestablishment completion message (e.g., a second communication procedure). In other words, when the selected cell is associated with a conditional configuration provided with the MCG configuration set, UE 120 may apply the conditional configuration to the selected cell based, at least in part, on a successful reestablishment with the selected cell. In this case, the latency to complete the reestablishment is reduced by avoiding the need to wait for an RRC reconfiguration message (to convey a new MCG configuration) after a successful reestablishment. In other words, based at least in part on maintaining the MCG configuration set after successful reestablishment, UE 120 may use the conditional configuration in the MCG configuration set for the selected cell with which connection is reestablished, rather than waiting for a new MCG configuration to be signaled for the selected cell. In contrast, if after cell selection, the selected cell is not a cell of the conditional configuration provided with the MCG configuration set, UE 120 may discard the MCG configuration set and the source cell configuration, and may subsequently receive a new MCG configuration for the source cell.
[0082] In some aspects, UE 120 may receive a handover command in conjunction with a CHO evaluation. For example, UE 120 may receive a handover command during the performance of a CHO evaluation. In this case, if the target cell in the handover command is a cell for which a conditional configuration is provided in an MCG configuration set, UE 120 may maintain the MCG configuration set and the source cell configuration after a successful reestablishment (e.g., a first communication procedure), and may apply the conditional configuration of the selected cell to the selected cell (e.g., in a second communication procedure). In some aspects, UE 120 may maintain the MCG configuration set after reestablishment based at least in part on receiving an indication from network node 110 to maintain the MCG configuration set. In contrast, if, after cell selection, the selected cell is not a cell for which a conditional configuration is provided in multiple MCG configurations, UE 120 may discard the conditional configuration set and the source cell configuration.
[0083] In some aspects, the UE may detect a failure during evaluation of a target PSCell set. For example, the UE 120 may detect an MCG RLF during evaluation of a target PSCells set. In this case, based at least in part on detecting an MCG RLF during evaluation of a target PSCell set (e.g., a first communication procedure), the UE 120 may stop evaluation, may maintain a conditional configuration set (e.g., an SCG configuration set), and may initiate an MCG failure information procedure (e.g., a second communication procedure). Additionally or alternatively, the UE 120 may detect an SCG failure during evaluation of a target PSCell set (e.g., a first communication procedure), may stop evaluation, may maintain a conditional configuration set (e.g., an SCG configuration set), and may initiate an SCG failure information procedure (e.g., a second communication procedure). In these cases, based at least in part on the UE 120 maintaining the conditional configuration, the network node 110 may provide an incremental value or offset value for the SCG configuration set when reconfiguring the UE 120, rather than a new SCG configuration set, thereby reducing network overhead.
[0084] In some aspects, UE 120 may detect a failure during conditional execution. For example, UE 120 may detect RLF on the MCG while performing a RACH procedure on a selected target PSCell. In this case, UE 120 may perform an RRC re-establishment procedure and may abandon initiating an MCG failure information procedure (e.g., based at least in part on the RACH procedure being in progress and the signaling bearer on the target secondary node not being established). Alternatively, UE 120 may wait until the RACH procedure is complete and may perform an MCG failure information procedure (e.g., based at least in part on the target node being established with a signaling bearer). In these cases, UE 120 may maintain a conditional configuration set (e.g., an SCG configuration set) because the conditional configuration set is still applicable after the failure is detected. Alternatively, if a timer expires during the RRC reestablishment procedure (e.g., UE 120 does not receive an RRC reestablishment message before timer T301 expires), UE 120 may release the SCG configuration set and transition from a first mode (e.g., RRC active mode) to a second mode (e.g., RRC idle mode).
[0085] As indicated above, Figure 5 are provided as examples. Other examples can be found in the Figure 5 The examples described are different.
[0086] Figure 6 6 is a diagram illustrating an example process 600, performed, for example, by a UE, according to the present disclosure. Example process 600 is an example in which a UE (eg, UE 120) performs operations associated with fault handling for multiple configured communication scenarios.
[0087] like Figure 6 As shown, in some aspects, process 600 may include receiving information from a network node identifying a conditional configuration set for a set of possible target cells associated with a first communication procedure, wherein the conditional configuration set is associated with a primary cell group or a secondary cell group (block 610). Figure 7 The depicted communications manager 140 and / or receiving component 702) may receive information from a network node identifying a conditional configuration set for a set of possible target cells associated with a first communication procedure, wherein the conditional configuration set is associated with a primary cell group or a secondary cell group, as described above.
[0088] like Figure 6 As further shown, in some aspects, process 600 may include communicating with the network node or another network node according to a conditional configuration associated with a second communication procedure in the set of conditional configurations (block 620). Figure 7 The depicted communication manager 140 and / or receiving component 702 or sending component 704) can communicate with the network node or another network node according to a conditional configuration in the set of conditional configurations associated with the second communication procedure, as described above.
[0089] Process 600 may include additional aspects, such as any single aspect or any combination of aspects described below and / or in conjunction with one or more other processes described elsewhere herein.
[0090] In a first aspect, process 600 includes detecting a failure associated with a random access channel procedure on a target cell for which a conditional handover is triggered; and storing a set of conditional configurations after a first communication procedure, wherein the first communication procedure is a recovery procedure for the failure associated with the random access channel procedure. By storing the set of conditional configurations, rather than discarding the set of conditional configurations, the conditional configurations are made available for use in a second communication procedure, thereby reducing latency in the recovery procedure.
[0091] In a second aspect, alone or in combination with the first aspect, process 600 includes receiving information indicating that a set of conditional configurations is to be maintained after a first communication procedure; and storing the set of conditional configurations after the first communication procedure includes storing the set of conditional configurations based at least in part on receiving the information indicating that the set of conditional configurations is to be maintained after the first communication procedure. By storing the set of conditional configurations based at least in part on receiving the message, rather than discarding the set of conditional configurations, the network node enables the UE to make the conditional configurations available for the second communication procedure, thereby reducing latency.
[0092] In a third aspect, alone or in combination with one or more of the first and second aspects, the first communication procedure is a recovery procedure not associated with a handover failure, and process 600 includes, in conjunction with the recovery procedure, selecting a cell associated with a conditional configuration in a conditional configuration set; and storing the conditional configuration set after the first communication procedure based at least in part on selecting the cell associated with the conditional configuration in the conditional configuration set. By storing the conditional configuration set based at least in part on selecting the cell associated with the conditional configuration set, the UE ensures that the conditional configurations that remain valid are maintained, and in another case, the conditional configurations that are no longer valid can be discarded, thereby saving memory.
[0093] In a fourth aspect, alone or in combination with one or more of the first to third aspects, process 600 includes receiving a handover command in conjunction with a conditional handover evaluation, wherein a target cell of the handover command is associated with a conditional configuration of a conditional configuration set; and storing the conditional configuration set after a first communication procedure based at least in part on the target cell being associated with the conditional configuration of the conditional configuration set. By storing the conditional configuration set based at least in part on selecting a target cell associated with the conditional configuration set, the UE ensures that the conditional configuration that remains valid is maintained, and in another case, the conditional configuration that is no longer valid can be discarded, thereby saving memory.
[0094] In a fifth aspect, alone or in combination with one or more of the first to fourth aspects, process 600 includes selecting a cell for a radio resource control reestablishment procedure, wherein the selected cell is associated with a conditional configuration in a conditional configuration set; and storing the conditional configuration set after the first communication procedure based at least in part on the selected cell being associated with the conditional configuration in the conditional configuration set. By storing the conditional configuration set based at least in part on selecting a cell associated with the conditional configuration set, the UE ensures that the conditional configuration that remains valid is maintained, and in another case, the conditional configuration that is no longer valid can be discarded, thereby saving memory.
[0095] In a sixth aspect, alone or in combination with one or more of the first to fifth aspects, process 600 includes, on a selected target primary and secondary cell, in conjunction with a random access channel procedure, executing a recovery procedure associated with conditional execution for a radio link failure on a primary cell group; and storing one or more conditional configurations in a conditional configuration set after a first communication procedure based at least in part on executing the recovery procedure, wherein one or more conditional configurations in the conditional configuration set are associated with a secondary cell group. In this case, recovery can be performed faster based at least in part on the availability of the conditional configuration set.
[0096] In a seventh aspect, alone or in combination with one or more of the first to sixth aspects, the recovery procedure is a radio resource control re-establishment procedure or a primary cell group failure information procedure.
[0097] In an eighth aspect, alone or in combination with one or more of the first to seventh aspects, process 600 includes detecting expiration of a timer associated with a recovery procedure; and releasing one or more conditional configurations in a set of conditional configurations based at least in part on detecting expiration of the timer. In this way, the UE can reuse memory after a period of time instead of maintaining stale conditional configurations (e.g., configurations that may no longer be useful for the connection).
[0098] In a ninth aspect, alone or in combination with one or more of the first to eighth aspects, process 600 includes transitioning from a first power state to a second power state based at least in part on detecting expiration of a timer. This can reduce power utilization of the UE.
[0099] In a tenth aspect, alone or in combination with one or more of the first to ninth aspects, process 600 includes applying a conditional configuration in the set of conditional configurations to a second communication procedure.
[0100] although Figure 6 An example block diagram of process 600 is shown, but in some aspects, process 600 may include Figure 6 The blocks depicted may be additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than those depicted.
