Abstract
Description
[Technical Field]
[0001] The present invention relates to an apparatus and a method used in a wireless communication system, and in particular, to a communication apparatus and a method for processing evaluation of a candidate target primary secondary cell (PSCell) (CTPS). [Background Art]
[0002] A Long Term Evolution (LTE®) system supporting the 3rd Generation Partnership Project (3GPP®) Rel-8 standard and / or 3GPP Rel-9 standard is developed by 3GPP as a successor to the Universal Mobile Telecommunications System (UMTS) to further enhance the performance of UMTS and meet the increasing needs of users.
[0003] As its name suggests, an LTE-Advanced (LTE-A) system is an evolved LTE system. The LTE-A system targets faster switching between power states, improves performance at the coverage edge of an evolved Node B (eNB), increases peak data rate and throughput, and includes advanced technologies such as carrier aggregation (CA) and uplink (UL) multiple-input multiple-output (UL-MIMO).
[0004] A Next Generation Radio Access Network (NG-RAN) supporting the 3GPP Rel-17 standard and / or 3GPP Rel-18 standard is developed to further enhance the LTE-A system. An NG-RAN comprises one or more next generation Node Bs (gNBs), and has characteristics such as a wider operating bandwidth, different numerologies for different frequency ranges, large-scale MIMO, and advanced channel coding.
[0005] In dual connectivity (DC), a user device (UE) is simultaneously connected to both a master node (MN) and a secondary node (SN). The MN and SN correspond to a primary cell (PCell) and a primary secondary cell (PSCell), respectively. Because UEs travel for long periods or at high speeds, they frequently perform conditional primary secondary cell (PSCell) change (CPC) or conditional PSCell addition (CPA) procedures. However, evaluating which candidate target PSCell (CTPS) will become the next PSCell before executing a CPC or CPA procedure is power-intensive and resource-intensive. Therefore, how to handle CTPS evaluation is a critical issue that needs to be addressed. [Overview of the project] [Problems that the invention aims to solve]
[0006] With this in mind, the present invention aims to provide a communication device and method for processing the evaluation of candidate target primary secondary cells (PSCells) (CTPS) in order to solve the above problems. [Means for solving the problem]
[0007] This is achieved by the communication device and method for processing the evaluation of the CTPS as described in the independent claims, respectively. Dependent claims relate to corresponding further developments and improvements.
[0008] As will become clearer from the following detailed description, a method for processing the evaluation of a plurality of CTPS of a communication device according to the claims includes: receiving a configuration from a network that includes a plurality of execution conditions (ECs) corresponding to each of the plurality of CTPS; evaluating the plurality of ECs to obtain a first evaluation event; executing a first PSCell procedure using the first CTPS of the plurality of CTPS in accordance with the first evaluation event; after executing the first PSCell procedure using the first CTPS in accordance with the first evaluation event, resetting at least one EC corresponding to at least one of the plurality of CTPS; and evaluating the at least one EC to obtain a second evaluation event.
[0009] The communication device according to the claim includes at least one storage device and at least one processing circuit coupled to the at least one storage device. The at least one storage device stores instructions, and the at least one processing circuit is configured to execute an instruction for receiving a setting from a network, which includes a plurality of execution conditions (ECs) corresponding to each of the plurality of CTPSs; an instruction for evaluating the plurality of ECs and obtaining a first evaluation event; an instruction for executing a first PSCell procedure using the first CTPS among the plurality of CTPS in accordance with the first evaluation event; an instruction for resetting at least one EC corresponding to at least one of the plurality of CTPS after executing the first PSCell procedure using the first CTPS in accordance with the first evaluation event; and an instruction for evaluating the at least one EC and obtaining a second evaluation event.
[0010] A method for processing the evaluation of multiple CTPS of a network according to the claim includes the steps of sending a setting to a communication device, each including a plurality of execution conditions (ECs) corresponding to the plurality of CTPS, and sending an EC setting to the communication device, wherein the setting and the EC setting allow the communication device to perform a first PSCell procedure using a first CTPS among the plurality of CTPS, and then reconfigure at least one EC corresponding to at least one of the plurality of CTPS. [Brief explanation of the drawing]

[Figure 14] This is a flowchart of the process according to one embodiment of the present invention. [Modes for carrying out the invention]
[0013] Figure 1 is a schematic diagram of a wireless communication system 10 according to one embodiment of the present invention. The wireless communication system 10 is simply composed of a network 12 and a plurality of communication devices 14. The wireless communication system 10 may support time division duplex (TDD) mode, frequency division duplex (FDD) mode, TDD-FDD joint operation mode, non-terrestrial network (NTN) mode, or license-assisted access (LAA) mode. That is, the network 12 and the communication devices 14 may communicate with each other via an FDD carrier, a TDD carrier, a license carrier (license serving cell), and / or an unlicensed carrier (unlicensed serving cell). Furthermore, the wireless communication system 10 may support carrier aggregation (CA). That is, the network 12 and the communication devices 14 may communicate with each other via a plurality of serving cells (e.g., a plurality of serving carriers), including a primary cell (e.g., a primary component carrier) and one or more secondary cells (e.g., secondary component carriers).
[0014] In Figure 1, the network 12 and communication device 14 are used for illustrative purposes to show the structure of the wireless communication system 10. In practice, the network 12 may be a universal terrestrial radio access network (UTRAN) including at least one node B (NB) in a universal mobile communications system (UMTS). In one embodiment, the network 12 may be an evolved UTRAN (E-UTRAN) including at least one evolved NB (eNB) and / or at least one relay node in a long-term evolution (LTE) system, LTE-Advanced (LTE-A) system, evolved LTE-A system, etc. In one embodiment, the network 12 may be a next-generation radio access network (NG-RAN) including at least one next-generation node B (gNB) and / or at least one fifth-generation (5G) base station (BS). In one embodiment, the gNB or 5G BS of the network 12 may include an NTN gateway and an NTN payload. In one embodiment, the network 12 may be any BS conforming to a specific communication standard for communicating with the communication device 14.
[0015] New Wireless Technologies (NR) are standards defined for 5G systems (or 5G networks) to provide a more performance-oriented integrated air interface. gNB is being introduced to enable 5G systems that support advanced features such as Enhanced Mobile Broadband (eMBB), Ultra-High Reliability Low Latency Communications (URLLC), and Massive Machine-Type Communications (mMTC). eMBB provides broadband services with wider bandwidth and low / medium latency. URLLC offers higher reliability and lower latency characteristics for applications (e.g., end-to-end communications). Examples of applications include the Industrial Internet, smart grids, infrastructure protection, remote surgery, and intelligent transportation systems (ITS). mMTC can support the Internet of Things (IoT) in 5G systems, including billions of connected devices and / or sensors.
[0016] Further, the network 12 may include at least one of UTRAN / E-UTRAN / NG-RAN and a core network, and the core network may include network entities such as a Mobility Management Entity (MME), a Serving Gateway (S-GW), a Packet Data Network (PDN) Gateway (P-GW), a Self-Organizing Network (SON) server and / or a Radio Network Controller (RNC), an Access and Mobility Management Function (AMF), a Session Management Function (SMF), a User Plane Function (UPF), and an Authentication Server Function (AUSF). In one embodiment, after the network 12 receives information transmitted by the communication device 14, the information is processed only by UTRAN / E-UTRAN / NG-RAN, and a judgment corresponding to the information is made by UTRAN / E-UTRAN / NG-RAN. In one embodiment, after UTRAN / E-UTRAN / NG-RAN forwards the information to the core network and the core network processes the information, a judgment corresponding to the information is made by the core network. In one embodiment, the information is processed by both UTRAN / E-UTRAN / NG-RAN and the core network, and these judgments are made after coordination and / or cooperation are performed by UTRAN / E-UTRAN / NG-RAN and the core network.
[0017] The communication device 14 may be a User Equipment (UE), a very small aperture terminal (VSAT), a low-cost device (e.g., a machine type communication (MTC) device), a device-to-device (D2D) communication device, a narrowband Internet of Things (NB-IoT), a mobile phone, a laptop, a tablet computer, an e-book, a portable computer system, or a combination thereof. In addition, the network 12 and the communication device 14 are regarded as a transmitter or a receiver according to a direction (i.e., a transmission direction). For example, in the case of an uplink (UL), the communication device 14 is the transmitter and the network 12 is the receiver; in the case of a downlink (DL), the network 12 is the transmitter and the communication device 14 is the receiver.
[0018] FIG. 2 is a schematic diagram of a communication device 20 according to an embodiment of the present invention. The communication device 20 may be the communication device 14 or the network 12 shown in FIG. 1, but is not limited thereto in this specification. The communication device 20 may include at least one processing circuit 200 such as a microprocessor or an application-specific integrated circuit (ASIC), at least one storage device 210, and at least one communication interface device 220. The at least one storage device 210 may be any data storage device capable of storing program code 214 accessed and executed by the at least one processing circuit 200. Examples of the at least one storage device 210 include, but are not limited to, a subscriber identity module (SIM), read-only memory (ROM), flash memory, random access memory (RAM), compact disc read-only memory (CD-ROM), digital versatile disc ROM (DVD-ROM), Blu-ray disc ROM (BD-ROM), magnetic tape, hard disk, optical data storage device, non-volatile storage device, non-transitory computer-readable medium (e.g., a tangible medium), and the like. The at least one communication interface device 220 is preferably at least one transceiver, and is used to transmit and receive signals (e.g., data, messages and / or packets) according to the processing result of the at least one processing circuit 200.
[0019] FIG. 3 is a flowchart of a process 30 according to an embodiment of the present invention. The process 30 may be used in a communication device (e.g., the communication device 14 of FIG. 1 or the communication device 20 of FIG. 2) for processing the evaluation of a plurality of candidate target primary-secondary cells (PSCells) (CTPSs). The process 30 may be compiled into the program code 214, and includes the following steps 300 to 312. In step 300, the process starts. In step 302, a configuration including a plurality of execution conditions (ECs) respectively corresponding to the plurality of CTPSs is received from a network. In step 304, the plurality of ECs are evaluated to obtain a first evaluation event. In step 306, the first PSCell procedure is executed using the first of several CTPS according to the first evaluation event. In step 308, after performing the first PSCell procedure using the first CTPS according to the first evaluation event, at least one EC corresponding to at least one of the multiple CTPS is reconfigured. Step 310 involves evaluating at least one EC to obtain a second evaluation event. Step 312 is the end.
[0020] According to process 30, the communication device receives a configuration from the network that includes multiple ECs, each corresponding to multiple CTPSs. The communication device then evaluates the multiple ECs to obtain a first evaluation event and, according to the first evaluation event, executes a first PSCell procedure (e.g., an initial PSCell procedure) using the first CTPS among the multiple CTPSs. After executing the first PSCell procedure using the first CTPS according to the first evaluation event, the communication device reconfigures (e.g., determines, selects, replaces) at least one EC corresponding to at least one CTPS among the multiple CTPSs. The communication device evaluates at least one EC (e.g., a reconfigured EC) to obtain a second evaluation event. In other words, the communication device does not need to evaluate all ECs. This improves the power consumption and load of the communication device.
[0021] The implementation of process 30 is not limited to the above description. The following embodiments may be applied to implement process 30.
[0022] In one embodiment, step 304 includes the steps of: determining whether a plurality of ECs are satisfied by a communication device; and obtaining a first evaluation event in response to the determination that a plurality of ECs are satisfied. In one embodiment, the configuration may be an Extended Selective Activation (eSA) configuration generated by the network. In one embodiment, the configuration further includes a plurality of configuration identifiers (IDs). In one embodiment, each of the plurality of configuration IDs corresponds to a plurality of CTPSs. In one embodiment, the configuration further includes a plurality of CTPS configurations. In one embodiment, each of the plurality of CTPS configurations corresponds to a plurality of CTPSs.
[0023] In one embodiment, step 306 includes the step of a communication device executing a first PSCell procedure using a first CTPS according to one of a plurality of CTPS settings in response to one of a plurality of ECs being satisfied. In one embodiment, the first CTPS corresponds to a CTPS setting and an EC. In one embodiment, the first PSCell procedure includes a conditional primary secondary cell (PSCell) change (CPC) procedure or a conditional PSCell add (CPA) procedure (for example, such a change procedure or add procedure).
[0024] In one embodiment, step 308 includes the step of the communication device reconfiguring at least one of a plurality of ECs according to the EC configuration from the network. For example, the communication device releases a plurality of ECs, receives the EC configuration from the network, and reconfigures at least one EC according to the EC configuration. In one embodiment, step 308 includes the step of the communication device reconfiguring at least one EC whose corresponding configuration ID is indicated in the EC configuration, and the step of determining that at least one CTPS corresponding to at least one EC is a cell applicable to evaluation. In one embodiment, the EC configuration is included in the configuration or received via dedicated control signaling (e.g., a Radio Resource Control (RRC) message). In one embodiment, the EC configuration includes at least one EC and at least one configuration ID corresponding to at least one EC. In one embodiment, the communication device retains a plurality of CTPS configurations and a plurality of configuration IDs after performing a first PSCell procedure with a first CTPS according to a first evaluation event.
[0025] In one embodiment, the configuration further includes multiple evaluation states (ES). In one embodiment, each of the multiple ES corresponds to a multiple EC. In one embodiment, each of the multiple ES indicates whether the corresponding EC is being evaluated or not. For example, an ES that is "active" indicates that the corresponding EC is being evaluated, and an ES that is "inactive" indicates that the corresponding EC is not being evaluated.
[0026] In one embodiment, step 308 includes the steps of: setting a plurality of ESs to a first state, which is either "active" or "inactive", by a communication device; receiving a first indicator from the network that indicates at least one of the plurality of ESs to the first ES; changing at least one of the first ESs from the first state to a second state, which is the other of "active" or "inactive", according to the first indicator; and determining at least one EC that corresponds to at least one second ES that is "active" among the plurality of ESs. That is, the communication device activates / deactivates the plurality of ESs (i.e., resets the plurality of ESs to "active / inactive") and updates the plurality of ESs according to the first indicator.
[0027] In one embodiment, the first indicator includes an activation indicator or a deactivation indicator (e.g., an activation indicator or a deactivation indicator). The activation indicator indicates that at least one first ES is activated. The deactivation indicator indicates that at least one first ES is deactivated. In one embodiment, the first indicator may be a media access control (MAC) control element (CE) or an RRC message. In one embodiment, if the first indicator includes an activation indicator (e.g., an activation indicator), at least one first ES is the same as at least one second ES. In one embodiment, if the first indicator includes a deactivation indicator (e.g., a deactivation indicator), at least one first ES is different from at least one second ES.
[0028] In one embodiment, step 308 includes the steps of: having a communication device hold a plurality of ESs; receiving a second indicator from the network indicating a plurality of updated ESs corresponding to a plurality of ECs; changing the plurality of ESs to a plurality of updated ESs according to the second indicator; and determining at least one EC corresponding to at least one of the plurality of ESs that is "active". That is, the second indicator indicates a plurality of updated states corresponding to a plurality of ESs, and the communication device updates the plurality of ESs according to the second indicator. Each of the plurality of updated states is either "active" or "inactive".
[0029] In one embodiment, the second indicator includes an ES indicator (e.g., an ES indicator). In one embodiment, the second indicator includes a plurality of configuration IDs and a plurality of updated ESs. In one embodiment, the second indicator includes a bitmap (e.g., a bitmap). In one embodiment, the bitmap includes a plurality of bits indicating a plurality of updated states, each corresponding to a plurality of ESs. For example, a bit that is "1" indicates that the corresponding updated state is "active", and a bit that is "0" indicates that the corresponding updated state is "inactive". For example, a bit that is "0" indicates that the corresponding updated state is "active", and a bit that is "1" indicates that the corresponding updated state is "inactive". For example, a bit that is "1" indicates that the corresponding updated state is "changed", and a bit that is "0" indicates that the corresponding updated state is "held". For example, a bit that is "0" indicates that the corresponding updated state is "changed", and a bit that is "1" indicates that the corresponding updated state is "held". In one embodiment, the second indicator may be a media access control (MAC) control element (CE) or an RRC message.
[0030] In one embodiment, the configuration further includes multiple cell lists. A cell list is a trigger condition (TC) for determining (e.g., judging) which EC to evaluate. A TC for a CTPS being satisfied means that the ID of the current PSCell of the communication device is in the cell list corresponding to the CTPS. Otherwise, the TC for the CTPS is not satisfied. In one embodiment, the multiple cell lists each correspond to multiple ECs and multiple CTPSs. In one embodiment, step 308 includes the steps of the communication device selecting at least one cell list from the multiple cell lists, each containing the CTPS ID of a first CTPS, and determining at least one EC corresponding to the at least one cell list. That is, the communication device determines (e.g., checks) whether the ID of the current PSCell of the communication device is in the multiple cell lists. In one embodiment, the cell lists may be null entries (i.e., they may not contain a CTPS ID). In one embodiment, if the cell list corresponding to the CTPS is a null entry, the communication device performs the CPA procedure using the CTPS. In one embodiment, the communication device executes a CPC procedure using the CTPS if the cell list corresponding to the CTPS is not a null entry.
[0031] In one embodiment, the configuration further includes a plurality of lists. The plurality of lists may be called a plurality of evaluation lists. In one embodiment, each of the plurality of lists corresponds to a plurality of CTPS. In one embodiment, step 308 includes the steps of the communication device selecting a list from the plurality of lists that corresponds to a first CTPS (e.g., the current PSCell of the communication device) and reconfiguring at least one EC according to the list. In one embodiment, the list includes at least one of at least one CTPS ID and at least one configuration ID corresponding to at least one EC. That is, the list indicates the EC to be evaluated. In one embodiment, step 308 includes the steps of the communication device reconfiguring at least one EC whose corresponding configuration ID is shown in the list and determining that at least one CTPS corresponding to at least one EC is a cell applicable to evaluation.
[0032] In one embodiment, step 310 includes the steps of determining whether at least one EC is satisfied by a communication device, and obtaining a second evaluation event in response to the determination that at least one EC is satisfied.
[0033] In one embodiment, the configuration further includes a threshold, which is an evaluation condition for determining (e.g., deciding) whether the communication device evaluates multiple ECs or at least one EC. In one embodiment, the satisfaction of the evaluation condition means that the signal quality of the current PSCell of the communication device is less than (or below) the threshold. Otherwise, the evaluation condition is not satisfied. In one embodiment, the communication device evaluates multiple ECs and generates a first evaluation event in response that the evaluation condition is satisfied. In one embodiment, the communication device evaluates at least one EC and generates a second evaluation event in response that the evaluation condition is satisfied. In one embodiment, the communication device does not evaluate multiple ECs or at least one EC in response that the evaluation condition is not satisfied. In one embodiment, signal quality may be, but is not limited to, the signal-to-noise ratio (SNR) or signal power.
[0034] In one embodiment, the network includes a master node (MN) or a secondary node (SN) (e.g., a master node (MN) or a secondary node (SN)). In one embodiment, the communication device executes a second PSCell procedure (e.g., a subsequent PSCell procedure) using the second CTPS among a plurality of CTPSs in accordance with a second evaluation event. In one embodiment, the second PSCell procedure includes a CPC procedure or a CPA procedure (e.g., a CPC procedure or a CPA procedure). In one embodiment, the communication device negotiates with the network and a plurality of CTPSs before receiving a configuration from the network. During negotiation, the plurality of CTPSs provide the communication device and the network with a plurality of CTPS configurations, respectively. In one embodiment, the communication device evaluates a plurality of ECs to obtain a first evaluation event in response to the communication device's current PSCell not being in the configuration. That is, if the communication device does not have information about the current PSCell (e.g., configuration ID, EC, and / or CTPS configuration) in the configuration, it evaluates all ECs that are in the configuration.
[0035] Figure 4 is a sequence diagram of process 40 according to one embodiment of the present invention. Figure 4 includes a network NW, a communication device CD, and three CTPSs (CTPS1 to CTPS3) of the communication device CD. The communication device CD negotiates with the network NW and the CTPSs CTPS1 to CTPS3 (step 400). Subsequently, the network NW sends the eSA configuration to the communication device (step 402). The eSA configuration, which can be referenced in Table 1, includes the configuration IDs (1 to 3) of the CTPS (CTPS1 to CTPS3), the ECs (EC1 to EC3), and the CTPS configurations (CTPS_Config1 to CTPS_Config3). The communication device CD evaluates the ECs EC1 to EC3 of CTPS1 to CTPS3 as CTPSs (step 404), and in response that EC2 as EC is satisfied, executes the CPC procedure or CPA procedure using CTPS2 as a CTPS (step 406). After executing the CPC or CPA procedure, the communication device CD may release EC1-EC3 as ECs (step 408). Consequently, the eSA configuration changes from Table 1 to Table 2. [Table 1] [Table 2]
[0036] In Figure 4, the communication device CD receives the EC configuration from the network NW (step 410). The EC configuration, which can be referenced in Table 3, includes the configuration IDs (1 and 3) and the ECs (EC1 and EC3). The communication device CD reconfigures EC1 and EC3 as ECs according to the EC configuration (step 412). Thus, the eSA configuration changes from Table 2 to Table 4. The communication device CD evaluates EC1 and EC3 as ECs for CTPS1 and CTPS3 as CTPS (step 414), and in response that the corresponding EC (EC1 or EC3 as EC) is satisfied, executes the CPC procedure or CPA procedure using CTPS1 or CTPS3 as CTPS (step 416). [Table 3] [Table 4]
[0037] Figure 5 is a sequence diagram of process 50 according to one embodiment of the present invention. Figure 5 includes a network NW, a communication device CD, and three CTPSs (CTPS1 to CTPS3) of the communication device CD. The communication device CD negotiates with the network NW and the CTPSs CTPS1 to CTPS3 (step 500). Subsequently, the network NW sends the eSA configuration to the communication device (step 502). The eSA configuration, which can be referenced in Table 5, includes the configuration IDs (1 to 3) of the CTPS (CTPS1 to CTPS3), the "active / inactive" ES, ECs (EC1 to EC3), and CTPS configurations (CTPS_Config1 to CTPS_Config3). The communication device CD evaluates only EC2 as the EC of CTPS2 as CTPS due to the "active" ES of CTPS2 as CTPS (step 504), and in response that EC2 as the EC is satisfied, executes the CPC procedure or CPA procedure using CTPS2 as CTPS (step 506). After executing the CPC procedure or CPA procedure, the communication device CD deactivates all ESs (step 508). Thus, the eSA settings are changed from Table 5 to Table 6. [Table 5] [Table 6]
[0038] In Figure 5, the network NW sends an activation indicator to the communication device CD (step 510). The activation indicators, which can be referenced in Table 7, include the configuration IDs (1 and 3) of the CTPS (CTPS1 and CTPS3). The activation indicators are used to indicate which ES is to be activated. The communication device CD updates ES1 and ES3 as ES according to the activation indicators (step 512). Thus, the eSA configuration changes from Table 6 to Table 8. The communication device CD evaluates EC1 and EC3 as EC due to the "active" ES of CTPS1 and CTPS3 as CTPS (step 514), and in response that the corresponding EC (EC1 or EC3 as EC) is satisfied, executes the CPC procedure or CPA procedure using CTPS1 or CTPS3 as CTPS (step 516). [Table 7] [Table 8]
[0039] Figure 6 is a sequence diagram of process 60 according to one embodiment of the present invention. Figure 6 includes a network NW, a communication device CD, and three CTPSs (CTPS1 to CTPS3) of the communication device CD. Steps 600 to 606 can be referred to from steps 500 to 506 and are not described herein for brevity. After performing the CPC procedure or CPA procedure, the communication device CD activates all ESs (step 608). Thus, the eSA settings are changed from Table 5 to Table 9. [Table 9]
[0040] In Figure 6, the network NW sends a deactivation indicator to the communication device CD (step 610). The deactivation indicator, which can be referenced in Table 10, includes the CTPS (CTPS2) configuration ID (2). The deactivation indicator is used to notify which ES is to be deactivated. The communication device CD updates ES2 as the ES according to the deactivation indicator (step 612). Thus, the eSA configuration is changed from Table 9 to Table 11. Steps 614 and 616 can be referenced from steps 514 and 516 and are not described herein for brevity. [Table 10] [Table 11]
[0041] Figure 7 is a sequence diagram of process 70 according to one embodiment of the present invention. Figure 7 includes a network NW, a communication device CD, and three CTPSs of the communication device CD, namely CTPS1 to CTPS3. Steps 700 to 706 can be referred to from steps 500 to 506 and are not described herein for brevity. After performing the CPC procedure or CPA procedure, the communication device CD retains all ESs (step 708). Thus, the eSA settings are not changed. Subsequently, the network NW sends an ES indicator to the communication device CD (step 710). In one embodiment, the ES indicator, as referenced in Table 12, includes the setting IDs (1 to 3) of the CTPSs (CTPS1 to CTPS3) and the updated ES, which is "active / deactivated". In one embodiment, the ES indicator includes a bitmap "101". A bit that is "1" indicates that the updated state of the ES of the corresponding CTPS is "active", and a bit that is "0" indicates that the updated state of the ES of the corresponding CTPS is "inactive". Therefore, the ES indicator containing bitmap "101" indicates ES that is "active" for CTPS1 and CTPS3 as CTPS, and ES that is "inactive" for CTPS2 as CTPS. [Table 12]
[0042] Subsequently, the communication device CD updates the ES according to the ES indicator (step 712). Thus, the eSA setting is changed from Table 5 to Table 13. Steps 714 and 716 can be described by referring to steps 514 and 516, and for brevity, they are not described herein. [Table 13]
[0043] Figure 8 is a sequence diagram of process 80 according to one embodiment of the present invention. Figure 8 includes a network NW, a communication device CD, and three CTPSs (CTPS1 to CTPS3) of the communication device CD. The communication device CD negotiates with the network NW and the CTPS1 to CTPS3 as CTPS (step 800). Subsequently, the network NW sends the eSA configuration to the communication device (step 802). The eSA configuration, which can be referenced in Table 14, includes the configuration IDs (1 to 3) of the CTPS (CTPS1 to CTPS3), a TC having a CTPS ID list (CTPS_ID_List1 to CTPS_ID_List3), ECs (EC1 to EC3), and CTPS configurations (CTPS_Config1 to CTPS_Config3). CTPS_ID_List1, as a CTPS ID list, includes the CTPS IDs of CTPS2 and CTPS3; CTPS_ID_List2, as a CTPS ID list, includes the CTPS IDs of CTPS1 and CTPS3; and CTPS_ID_List3, as a CTPS ID list, includes the CTPS IDs of CTPS1 and CTPS2. [Table 14]

Since CTPS_ID_List1 and CTPS_ID_List3 as CTPS ID lists include the CTPS ID of CTPS2 as CTPS (i.e., the current PSCell of the communication device), the communication device CD selects CTPS_ID_List1 and CTPS_ID_List3 as CTPS ID lists and determines EC1 and EC3 as ECs corresponding to CTPS_ID_List1 and CTPS_ID_List3 as CTPS ID lists (step 808). The communication device CD evaluates EC1 and EC3 as ECs (step 810), and in response that the corresponding EC (EC1 or EC3 as EC) is satisfied, executes the CPC procedure or CPA procedure using CTPS1 or CTPS3 as CTPS (step 812).
[0045] Figure 9 is a sequence diagram of process 90 according to one embodiment of the present invention. Figure 9 includes a network NW, a communication device CD, and three CTPSs (CTPS1 to CTPS3) of the communication device CD. The communication device CD negotiates with the network NW and the CTPSs 1 to 3 (step 900). Subsequently, the network NW transmits the eSA settings to the communication device (step 902).
[0046] The eSA configurations referencing Table 15 include the configuration IDs (1-3) of CTPS (CTPS1-CTPS3), evaluation lists with configuration ID lists (Config_ID_List1-Config_ID_List3), ECs (EC1-EC3), and CTPS configurations (CTPS_Config1-CTPS_Config3). Config_ID_List1, as a configuration ID list, includes configuration IDs 2 and 3; Config_ID_List2, as a configuration ID list, includes configuration IDs 1 and 3; and Config_ID_List3, as a configuration ID list, includes configuration IDs 1 and 2.

CTPS_ID_List4, as a CTPS ID list, includes the CTPS IDs of CTPS2 and CTPS3; CTPS_ID_List5, as a CTPS ID list, includes the CTPS IDs of CTPS1 and CTPS3; and CTPS_ID_List6, as a CTPS ID list, includes the CTPS IDs of CTPS1 and CTPS2. [Table 15] [Table 16]
[0047] In Figure 9, the communication device CD evaluates EC1 to EC3 as ECs for CTPS1 to CTPS3 as CTPS (step 904), and in response that EC2 as EC is satisfied, executes the CPC procedure or CPA procedure using CTPS2 as CTPS (step 906). The communication device CD selects an evaluation list for CTPS2 as CTPS (for example, Config_ID_List2 as a configuration ID list containing configuration IDs 1 and ID 3, or CTPS_ID_List5 as a CTPS ID list containing the CTPS IDs of CTPS1 and CTPS3 as CTPS) (step 908). Since the evaluation list for CTPS2 as CTPS indicates CTPS1 and CTPS3 as CTPS, the communication device CD determines EC1 and EC3 as ECs corresponding to CTPS1 and CTPS3 as CTPS (step 910). Steps 912 and 914 can be referred to in steps 810 and 812 and are not described herein for brevity.
[0048] Figure 10 is a sequence diagram of process 100 according to one embodiment of the present invention. Figure 10 includes a network NW, a communication device CD, and three CTPSs (CTPS1 to CTPS3) of the communication device CD. The communication device CD negotiates with the network NW and the CTPS1 to CTPS3 as CTPSs (step 1000). Subsequently, the network NW transmits the eSA configuration to the communication device (step 1002). The eSA configuration, which can be referenced in Table 17, includes the configuration IDs (1 to 3) of the CTPS (CTPS1 to CTPS3), ECs (EC1 to EC3), and CTPS configurations (CTPS_Config1 to CTPS_Config3), and further includes evaluation conditions having a threshold T. [Table 17]
[0049] In Figure 10, communication device CD evaluates EC1 to EC3 as ECs of CTPS1 to CTPS3 as CTPSs in response to the evaluation conditions being met (step 1004). That is, communication device CD evaluates EC1 to EC3 as ECs if the signal quality of the current PSCell of communication device CD is less than the threshold T. Communication device CD executes the CPC procedure or CPA procedure using CTPS2 as a CTPS in response to EC2 as an EC being met (step 1006). Subsequently, communication device CD evaluates EC1 and EC3 as ECs of CTPS1 and CTPS3 as CTPSs in response to the evaluation conditions being met (step 1008), and executes the CPC procedure or CPA procedure using CTPS1 or CTPS3 as a CTPS in response to the corresponding EC (EC1 or EC3 as an EC) being met (step 1010).
[0050] Figure 11 is a flowchart of process 110 according to one embodiment of the present invention. Process 110 may be used in a communication device (for example, communication device 14 in Figure 1 or communication device 20 in Figure 2) to process the evaluation of multiple candidate target primary secondary cells (PSCells) (CTPS). Process 110 may be compiled into program code 214 and includes the following steps 1100 to 1108. Step 1100 is to begin. In step 1102, the network receives a configuration that includes multiple first execution conditions (ECs) and multiple relaxation measures (RMCs), each corresponding to multiple CTPSs. In step 1104, at least one of the multiple first ECs is evaluated, and in response to at least one of the multiple RMCs being satisfied, an evaluation event is generated. In step 1106, the PSCell procedure is executed using one of the multiple CTPS according to the evaluation event. Step 1108 is the end.
[0051] According to process 110, the communication device receives a configuration from the network that includes multiple first ECs and multiple RMCs, each corresponding to multiple CTPSs. The communication device then evaluates at least one of the multiple first ECs and generates an evaluation event in response to at least one of the multiple RMCs being satisfied. The communication device executes a PSCell procedure (initial PSCell procedure or subsequent PSCell procedure) using one of the multiple CTPSs according to the evaluation event. That is, the multiple RMCs are trigger conditions for evaluating the multiple first ECs. The communication device evaluates the ECs if the corresponding RMCs are satisfied. This improves the power consumption and load of the communication device.
[0052] The implementation of process 110 is not limited to the above description. The following embodiments may be applied to implement process 110.
[0053] In one embodiment, step 1104 includes the steps of determining whether at least one first EC is satisfied by a communication device, and generating an evaluation event in response to the determination that at least one first EC is satisfied.
[0054] In one embodiment, the configuration may be an Extended Selective Activation (eSA) configuration generated by the network. In one embodiment, the configuration further includes multiple configuration IDs. In one embodiment, each of the multiple configuration IDs corresponds to a multiple CTPS. In one embodiment, the configuration further includes multiple CTPS configurations. In one embodiment, each of the multiple CTPS configurations corresponds to a multiple CTPS.
[0055] In one embodiment, step 1106 includes the step of a communication device executing a PSCell procedure using the CTPS according to one of a plurality of CTPS settings in response to the EC being satisfied by one of a plurality of first ECs. In one embodiment, the CTPS corresponds to the CTPS setting and the EC. In one embodiment, the PSCell procedure includes a CPC procedure or a CPA procedure (for example, a CPC procedure or a CPA procedure).
[0056] In one embodiment, a plurality of first ECs each correspond to a plurality of RMCs. In one embodiment, a plurality of RMCs each include a plurality of reference symbol received power (RSRP) thresholds. The RMC of the CTPS being satisfied means that the RSRP of the CTPS is less than (or below) the RSRP threshold of the RMC.
[0057] Table 18 shows an embodiment of the following configuration. Assuming that the communication device has three CTPSs, Table 18 includes the configuration IDs (1 to 3) of the CTPS (CTPS1 to CTPS3), the RMC with RSRP thresholds (RSRP_T1 to RSRP_T3), the ECs (EC1 to EC3), and the CTPS configurations (CTPS_Config1 to CTPS_Config3). In process 110, the communication device may receive Table 18 from the network and may perform steps 1104 to 1106 according to Table 18. [Table 18]
[0058] In one embodiment, each of the multiple RMCs includes multiple relaxation parameters. That is, each of the multiple relaxation parameters is set by each of the multiple RMCs. In one embodiment, the multiple relaxation parameters are integers.
[0059] In one embodiment, step 1104 includes the steps of: generating at least one second measurement period (e.g., relaxed measurement period) by extending at least one first measurement period (e.g., normal measurement period) of at least one evaluation measurement of at least one first EC by at least one relaxation parameter among a plurality of relaxation parameters, in response to at least one RMC being satisfied by the communication device; and generating an evaluation event by evaluating at least one first EC according to at least one second measurement period. In one embodiment, at least one first EC corresponds to at least one RMC. In one embodiment, at least one first measurement period is included in at least one first EC. In one embodiment, at least one evaluation measurement of at least one first EC is used to evaluate at least one first EC. That is, the communication device evaluates at least one first EC by performing at least one evaluation measurement.
[0060] Table 19 shows an embodiment of the following configuration. Assuming that the communication device has three CTPSs, Table 19 includes the configuration IDs (1 to 3) of the CTPSs (CTPS1 to CTPS3), the RMC having RSRP thresholds (RSRP_T1 to RSRP_T3) and relaxation parameters (RP1 to RP3), the ECs (EC1 to EC3), and the CTPS configurations (CTPS_Config1 to CTPS_Config3). The communication device adjusts the measurement period according to Table 19 and evaluates the ECs. For example, if the PSRP of CTPS1 as a CTPS is smaller than the RSRP threshold RSRP_T1, the communication device extends the measurement period of EC1 as an EC by the relaxation parameter RP1. For example, if the PSRP of CTPS2 as a CTPS is smaller than the RSRP threshold RSRP_T2, the communication device extends the measurement period of EC2 as an EC by the relaxation parameter RP2. For example, the communication device extends the measurement period of EC3 as EC by the relaxation parameter RP3, depending on whether the PSRP of CTPS3 as CTPS is smaller than the RSRP_T3 as the RSRP threshold. [Table 19]
[0061] In one embodiment, the configuration further includes a plurality of second ECs, each of which corresponds to a plurality of RMCs. That is, the network may configure a plurality of ECs for a single CTPS. In one embodiment, a plurality of first ECs (e.g., normal ECs) each include a plurality of first measurement periods (e.g., normal measurement periods). In one embodiment, a plurality of second ECs (e.g., relaxed ECs) each include a plurality of second measurement periods (e.g., relaxed measurement periods). In one embodiment, the first measurement period in the first EC is smaller than (or shorter than) the second measurement period in the second EC, and the first and second ECs correspond to the same RMC. In one embodiment, step 1104 may be replaced with "evaluate at least one of the plurality of second ECs instead of at least one first EC to generate an evaluation event in response that at least one RMC is satisfied." That is, at least one second EC is used for evaluation. In one embodiment, at least one second EC corresponds to at least one RMC.
[0062] Table 20 shows an embodiment of the following configuration. Assuming that the communication device has three CTPSs, Table 20 includes the configuration IDs (1 to 3) of the CTPSs (CTPS1 to CTPS3), the RMC having RSRP thresholds (RSRP_T1 to RSRP_T3), the EC having normal ECs (N_EC1 to N_EC3) and relaxed ECs (R_EC1 to R_EC3), and the CTPS configurations (CTPS_Config1 to CTPS_Config3). For example, the communication device may evaluate R_EC1 as a relaxed EC instead of N_EC1 as a normal EC in response that the PSRP of CTPS1 as a CTPS is smaller than RSRP_T1 as an RSRP threshold. For example, the communication device may evaluate R_EC2 as a relaxed EC instead of N_EC2 as a normal EC in response that the PSRP of CTPS2 as a CTPS is smaller than RSRP_T2 as an RSRP threshold. For example, a communication device may evaluate R_EC3 as a relaxed EC instead of N_EC3 as a normal EC in response to the PSRP of CTPS3 as a CTPS being smaller than RSRP_T3 as an RSRP threshold. [Table 20]
[0063] In one embodiment, the communication device sends a report to the network in response that at least one RMC is satisfied. In one embodiment, the report includes at least one CTPS ID, and at least one CTPS ID corresponds to at least one RMC. In one embodiment, the network determines whether to reconfigure at least one first EC according to the report. In one embodiment, the network sends an EC configuration to the communication device in response to reconfiguring at least one first EC. In one embodiment, the EC configuration includes at least one reconfigured first EC and at least one configuration ID corresponding to the at least one reconfigured first EC.
[0064] In one embodiment, the communication device transmits priority information to the network before receiving a configuration and / or after evaluating at least one first EC. In one embodiment, the PSCell procedure is either an initial PSCell procedure or a subsequent PSCell procedure. In one embodiment, the priority information is used to notify the network that the communication device prioritizes adjusting an evaluation target (e.g., an EC in CTPS) or adjusting an evaluation measurement (e.g., a measurement period) in a subsequent PSCell procedure. In one embodiment, the priority information is generated from the application layer of the communication device according to a predefined UE profile. In one embodiment, the network determines whether to reconfigure multiple first ECs according to the priority information. In one embodiment, the network transmits an EC configuration to the communication device in response to reconfiguring at least one first EC. In one embodiment, the EC configuration includes at least one reconfigured first EC and at least one configuration ID corresponding to the at least one reconfigured first EC.
[0065] In one embodiment, the configuration further includes a threshold, which is an evaluation condition for determining (e.g., deciding) whether the communication device evaluates at least one first EC. In one embodiment, the satisfaction of the evaluation condition means that the signal quality of the current PSCell of the communication device is less than (or below) the threshold. Otherwise, the evaluation condition is not satisfied. In one embodiment, the communication device evaluates at least one first EC and generates an evaluation event in response to the evaluation condition and at least one RMC being satisfied. In one embodiment, the communication device does not evaluate at least one first EC in response to the evaluation condition not being satisfied. In one embodiment, signal quality may be, but is not limited herein, the signal-to-noise ratio (SNR) or signal power.
[0066] In one embodiment, the network includes a master node (MN) or a secondary node (SN) (for example, a master node (MN) or a secondary node (SN)). In one embodiment, the communication device negotiates with the network and multiple CTPSs before receiving configurations from the network. During negotiation, the multiple CTPSs each provide multiple CTPS configurations to the communication device and the network.
[0067] Figure 12 is a sequence diagram of process 120 according to one embodiment of the present invention. Figure 12 includes a network NW, a communication device CD, and three CTPSs (CTPS1 to CTPS3) of the communication device CD. The communication device CD negotiates with the network NW and the CTPSs 1 to CTPS3 (step 1200). The network NW then sends the eSA configuration to the communication device CD (step 1202). The eSA configuration can be found in Table 18, but for brevity it is not described herein. The communication device CD evaluates the first EC and, in response that the first RMC (e.g., the first RSRP threshold) corresponding to the first EC is met, generates a first evaluation event (step 1204) and sends a first report to the network NW containing the first CTPS ID corresponding to the first RMC (step 1206). In response to the first EC being satisfied, the communication device CD executes the CPC procedure using the first CTPS corresponding to the first EC (for example, one of CTPS1 to CTPS3 as the CTPS) (step 1208).
[0068] In Figure 12, the communication device CD evaluates the second EC and, in response that the second RMC (e.g., the second RSRP threshold) corresponding to the second EC is satisfied, generates a second evaluation event (step 1210) and sends a second report to the network NW containing the second CTPS ID corresponding to the second RMC (step 1212). The network NW reconfigures the EC according to the second report (step 1214) and sends the EC configuration, including the reconfigured EC, to the communication device CD (step 1216). Thus, the communication device CD reconfigures the EC in the eSA configuration according to the EC configuration (step 1218).
[0069] Figure 13 is a sequence diagram of process 130 according to one embodiment of the present invention. Figure 13 includes a network NW, a communication device CD, and three CTPSs (CTPS1 to CTPS3) of the communication device CD. The communication device CD transmits priority information to the network NW (step 1300). Steps 1302 to 1306 can be described by referring to steps 1200 to 1204 and are not described herein for brevity. The communication device CD transmits priority information to the network NW (step 1308) and, in response that the first EC is satisfied, executes a CPC procedure or a CPA procedure using the first CTPS corresponding to the first EC (e.g., one of CTPS1 to CTPS3 as a CTPS) (step 1310).
[0070] In Figure 13, the communication device CD evaluates the second EC and generates a second evaluation event in response to the second RMC (e.g., the second RSRP threshold) corresponding to the second EC being met (step 1312). The communication device CD sends priority information to the network NW (step 1314). The network NW reconfigures the EC according to the priority information (step 1316) and sends the EC configuration, including the reconfigured EC, to the communication device CD (step 1318). Thus, the communication device CD reconfigures the EC in the eSA configuration according to the EC configuration (step 1320).
[0071] Figure 14 is a flowchart of process 140 according to one embodiment of the present invention. Process 140 may be used in a network (for example, network 12 in Figure 1) to process the evaluation of multiple CTPS. Process 140 may be compiled into program code 214 and includes the following steps 1400 to 1406. Step 1400 is to begin. In step 1402, a configuration including multiple ECs corresponding to multiple CTPSs is sent to the communication device. In step 1404, the EC settings are sent to the communication device. Step 1406 is the end.
[0072] According to process 140, the network sends a configuration to the communication device, each containing multiple ECs corresponding to multiple CTPSs. The network then sends the EC configuration to the communication device. The configuration and EC configuration allow the communication device to perform a first PSCell procedure using the first CTPS among the multiple CTPSs (e.g., the communication device's current PSCell), and then reconfigure at least one EC corresponding to at least one of the multiple CTPSs. That is, the transmitted configuration and EC configuration may be used / applied to reconfigure (e.g., determine) at least one EC to be evaluated. The communication device does not have to evaluate all ECs according to the transmitted configuration and EC configuration. This improves the power consumption and load of the communication device.

[0074] In one embodiment, the configuration further includes multiple configuration IDs, each corresponding to multiple CTPS. In one embodiment, the configuration further includes multiple CTPS configurations. In one embodiment, each of the multiple CTPS configurations corresponds to multiple CTPS.

[0075] In one embodiment, the EC configuration indicates at least one configuration ID corresponding to at least one EC. In one embodiment, the EC configuration is included in the configuration or received via dedicated control signaling (e.g., RRC message). In one embodiment, the EC configuration includes at least one EC and at least one configuration ID.
[0076] In one embodiment, the configuration further includes a plurality of lists. The plurality of lists may be called a plurality of evaluation lists. In one embodiment, each of the plurality of lists corresponds to a plurality of CTPS. In one embodiment, one of the plurality of lists allows the communication device to reconfigure at least one EC. In one embodiment, the list corresponds to a first CTPS. In one embodiment, the list includes at least one of at least one CTPS ID and at least one configuration ID corresponding to at least one EC. In one embodiment, the list indicates at least one configuration ID corresponding to at least one EC. That is, the list indicates the EC to be evaluated.
[0077] In one embodiment, the network includes an MN or SN (for example, an MN or SN). In one embodiment, the network negotiates with the communication device and multiple CTPSs before sending the configuration to the communication device. During negotiation, the multiple CTPSs each provide multiple CTPS configurations to the communication device and the network.
