Measurement Report Delay for Pre-Configured Measurement Gaps

Abstract

A user equipment (UE) configured for operation in a fifth generation new radio (5G NR) network performs synchronization signal block (SSB)-based radio resource management (RRM) measurements with or without a measurement gap. The UE may decode network signaling that triggers a change in the status of a preconfigured measurement gap. The UE may perform SSB-based RRM measurements with a measurement gap when the network signaling that triggered the change in the preconfigured measurement gap status activated the preconfigured measurement gap. The UE may deactivate the preconfigured measurement gap and perform SSB-based RRM measurements without a measurement gap when the network signaling that triggered the change in the preconfigured measurement gap status deactivated the preconfigured measurement gap. The UE may also encode for transmission to the network a measurement report that may include measurement results from SSB-based RRM measurements performed during a measurement report delay period. A number of samples of the SSB-based RRM measurements included in the measurement report may be based at least in part on the change in the measurement gap status triggered during the measurement report delay period.

Description

Technical Field

[0001] [Claims of Priority] This application claims priority to U.S. Provisional Patent Application No. 63 / 257,909, filed October 20, 2021 [Reference No. AD9709-Z], the entire content of which is incorporated herein by reference.

[0002] Embodiments relate to wireless communication. Some embodiments relate to wireless networks including 5th generation (5G) networks including 3GPP (Registered Trademark) (3rd Generation Partnership Project) and 5G New Radio (NR) (or 5G-NR) networks. Some embodiments relate to 6th generation (6G) networks. Some embodiments relate to measurement reports and event trigger reports.

Background Art

[0003] Mobile communication has evolved significantly from early voice systems to today's highly sophisticated integrated communication platforms. With the increasing number of different types of devices communicating with various network devices, the use of 3GPP 5G NR systems is increasing. The prevalence of mobile devices (user equipment or UE) in modern society continues to drive the demand for various networked devices in many different environments. 5G NR wireless systems are emerging and are expected to achieve even higher speeds, connectivity, and user usability, as well as to increase throughput, coverage, and robustness and reduce latency and operational and capital expenditures. 5G-NR networks are evolving based on 3GPP LTE Advanced, along with additional potential new radio access technologies (RATs), to enrich people's lives with seamless wireless connectivity solutions that provide high-speed and rich content and services. Since current cellular network frequencies are saturated, higher frequencies such as millimeter wave (mmWave) frequencies can be beneficial due to their high bandwidth.

[0004] One issue associated with operation in a 5G NR network is measurement reporting. In the RRC_CONNECTED state, the UE measures multiple beams (at least one) of a cell, averages the measurement results (power values) to derive the cell quality. In doing so, the UE is configured to consider a subset of the detected beams. Filtering is performed at two different levels, namely, at the physical layer to derive the beam quality and then, at the RRC level to derive the cell quality from multiple beams. The cell quality from beam measurements is derived in the same way for both the serving cell and non-serving cells. The measurement report may include the measurement results of the best beam if the UE is configured to include them for the gNodeB (gNB).

Best Mode for Carrying Out the Invention

[0010] The following description and drawings fully illustrate specific embodiments so as to enable those skilled in the art to practice the embodiments. Other embodiments may incorporate structural, logical, electrical, process, and other changes. Portions and features of some embodiments may be included in or substituted for those of other embodiments. The embodiments recited in the claims cover all available equivalents of those claims.

[0011] Some embodiments are directed to a user equipment (UE) configured for operation in a Fifth-Generation New Radio (5G NR) network. The UE performs Synchronization Signal Block (SSB)-based radio resource management (RRM) measurements regardless of the presence or absence of a measurement gap. The UE may encode a measurement report that includes measurement results from SSB-based RRM measurements performed during a measurement reporting delay period for transmission to the network. The number of samples of the SSB-based RRM measurements included in the measurement report may be at least partially based on a change in the measurement gap status triggered during the measurement reporting delay period. In some embodiments, the UE may determine the length of the measurement reporting delay period depending on whether a switch in the gap activation status has occurred during the measurement reporting delay period. These embodiments as well as other embodiments are described in more detail below.

[0012] FIG. 1A shows the architecture of a network according to some embodiments. Network 140A is shown to include user equipment (UE) 101 and UE 102. UE 101 and 102 are shown as smartphones (e.g., handheld touch screen mobile computing devices connectable to one or more cellular networks), but may also include any mobile or non-mobile computing device such as a personal digital assistant (PDA (registered trademark)), pager, laptop computer, desktop computer, wireless headset, drone, or any other computing device including a wired and / or wireless communication interface. UE 101 and 102 may be collectively referred to herein as UE 101, and UE 101 may be used to execute one or more of the techniques disclosed herein.

[0013] Any of the wireless links described herein (e.g., as used in network 140A or any other shown network) may operate according to any exemplary wireless communication technology and / or standard.

[0014] LTE and LTE-Advanced are standards for wireless communication of high-speed data for UEs such as mobile phones. In LTE-Advanced and various wireless systems, carrier aggregation is a technique in which multiple carrier signals operating at different frequencies can be used to carry communications for a single UE, and thus the bandwidth available to a single device is increased. In some embodiments, carrier aggregation may be used when one or more component carriers operate at unlicensed frequencies.

[0015] The embodiments described herein can be used, for example, in the context of any spectrum management scheme including dedicated license spectrum, unlicensed spectrum, (licensed) shared spectrum (such as license shared access (LSA) at 2.3 - 2.4 GHz, 3.4 - 3.6 GHz, 3.6 - 3.8 GHz and further frequencies, and spectrum access system (SAS) at 3.55 - 3.7 GHz and further frequencies, etc.).

[0016] The embodiments described herein can also be applied, in particular, to 3GPP NR (New Radio), by allocating an OFDM carrier data bit vector to a corresponding symbol resource, to different single carriers or OFDM flavors (CP - OFDM, SC - FDMA, SC - OFDM, filter bank - based multi - carrier (FBMC), OFDMA, etc.).

[0017] In some embodiments, either of UE101 and UE102 can include an Internet of Things (IoT) UE or a Cellular IoT (CIoT) UE, which can include a network access layer designed for low-power IoT applications using temporary UE connections. In some embodiments, either of UE101 and UE102 can include a NarrowBand (NB) IoT UE (such as an Extended NB-IoT (eNB-IoT) UE and a Further Extended (FeNB-IoT) UE, etc.). The IoT UE can utilize technologies such as Machine-to-Machine (M2M) or Machine-Type Communication (MTC) that exchange data with an MTC server or device via a Public Land Mobile Network (PLMN), Proximity-Based Services (ProSe) or Device-to-Device (D2D) communication, a sensor network, or an IoT network. The M2M or MTC exchange of data can be an exchange of data initiated by a machine. The IoT network includes interconnecting IoT UEs, which may include uniquely identifiable embedded computing devices (within the Internet infrastructure) having a temporary connection. The IoT UE can execute background applications (such as keep-alive messages, status updates, etc.) to facilitate connection to the IoT network.

[0018] In some embodiments, either of UE101 and UE102 can include an Extended MTC (eMTC) UE or a Further Extended MTC (FeMTC) UE.

[0019] UEs 101 and 102 may be configured to be communicatively coupled, for example, to be connected to a radio access network (RAN) 110. The RAN 110 can be, for example, an evolved universal mobile telecommunications system (UMTS) terrestrial radio access network (E-UTRAN), a NextGen RAN (NG RAN), or some other type of RAN. UEs 101 and 102 each utilize connections 103 and 104, each of which includes a physical communication interface or layer (discussed in more detail below); in this example, connections 103 and 104 are shown as air interfaces enabling a communicative coupling and may comply with cellular communication protocols such as a global system for mobile communications (GSM) protocol, a code division multiple access (CDMA) network protocol, a push-to-talk (PTT) protocol, a PTT over cellular (POC) protocol, a universal mobile telecommunications system (UMTS) protocol, a 3GPP long term evolution (LTE) protocol, a fifth generation (5G) protocol, a new radio (NR) protocol, etc.

[0020] In one aspect, UEs 101 and 102 may further directly exchange communication data via a ProSe interface 105. The ProSe interface 105 may alternatively be referred to as a sidelink interface including one or more logical channels including, but not limited to, a physical sidelink control channel (PSCCH), a physical sidelink shared channel (PSSCH), a physical sidelink discovery channel (PSDCH), and a physical sidelink broadcast channel (PSBCH).

[0021] UE102 is shown as being configured to access access point (AP) 106 via connection 107. Connection 107 can include, for example, a local wireless connection such as a connection compliant with any IEEE802.11 protocol, according to which AP106 can include a Wi-Fi (registered trademark) router. In this example, AP106 is shown as being connected to the Internet without being connected to the core network of the wireless system (described in more detail below).

[0022] RAN110 can include one or more access nodes that enable connections 103 and 104. These access nodes (ANs) can be referred to as base stations (BSs), NodeBs, evolved NodeBs (eNBs), next-generation NodeBs (gNBs), RAN nodes, etc., and can include terrestrial stations (e.g., terrestrial access points) or satellite stations that provide coverage within a geographical area (e.g., a cell). In some embodiments, communication nodes 111 and 112 can be transmission / reception points (TRPs). In the case where communication nodes 111 and 112 are NodeBs (e.g., eNBs or gNBs), one or more TRPs can function within the communication cell of the NodeB. RAN110 can include one or more RAN nodes that provide macrocells, e.g., macro RAN node 111, and one or more RAN nodes that provide femtocells or picocells (e.g., cells having a smaller coverage area, a smaller user capacity, or a higher bandwidth compared to a macrocell), e.g., low-power (LP) RAN node 112.

[0023] Either of RAN nodes 111 and 112 can terminate the air interface protocol and serve as the first contact point to UEs 101 and 102. In some embodiments, either of RAN nodes 111 and 112 can perform various logical functions for RAN 110, including but not limited to radio bearer management, dynamic radio resource management and data packet scheduling for uplink and downlink, and mobility management, such as radio network controller (RNC) functions. In one example, either of nodes 111 and / or 112 can be a next-generation NodeB (gNB), evolved NodeB (eNB), or another type of RAN node.

[0024] RAN 110 is shown as communicatively coupled to core network (CN) 120 via S1 interface 113. In an embodiment, CN 120 can be an evolved packet core (EPC) network, NextGen packet core (NPC) network, or some other type of CN (e.g., as shown with reference to FIGS. 1B - 1C). In this regard, S1 interface 113 is split into two parts: an S1-U interface 114 that carries traffic data between RAN nodes 111 and 112 and serving gateway (S-GW) 122, and an S1-mobility management entity (MME) interface 115 that is a signaling interface between RAN nodes 111 and 112 and MME 121.

[0025] In this embodiment, CN120 includes a Mobility Management Entity (MME) 121, a Serving Gateway (S-GW) 122, a Packet Data Network (PDN) Gateway (P-GW) 123, and a Home Subscriber Server (HSS) 124. The MME 121 may be similar to the control plane and functions of a legacy Serving General Packet Radio Service (GPRS) Support Node (SGSN). The MME 121 may manage mobility embodiments in access such as gateway selection and Tracking Area List management. The HSS 124 may include a database for network users, including subscription-related information for supporting the handling of communication sessions by network entities. CN120 may include one or several HSSs 124 depending on the number of mobile subscribers, device capacity, network configuration, etc. For example, the HSS 124 may be able to provide support for routing / roaming, authentication, authorization, naming / address resolution, location dependency, etc.

[0026] The S-GW 122 may terminate the S1 interface 113 towards the Radio Access Network (RAN) 110 and route data packets between the RAN 110 and the CN 120. Additionally, the S-GW 122 may be a local mobility anchor point for RAN node handovers and may provide an anchor for inter-3GPP mobility. Other roles of the S-GW 122 may include lawful interception, charging, and any policy enforcement.

[0027] The P-GW 123 can terminate the SGi interface towards the PDN. The P-GW 123 can route data packets between the EPC network 120 and an external network such as a network including an application server 184 (alternatively referred to as an Application Function (AF)) via the Internet Protocol (IP) interface 125. The P-GW 123 can also communicate data to other external networks 131A, which can include the Internet, an IP Multimedia Subsystem (IMS) network, and other networks. Generally, the application server 184 can be an element that provides an application that uses IP bearer resources together with a core network (e.g., a UMTS Packet Service (PS) domain, an LTE PS data service, etc.). In this aspect, the P-GW 123 is shown as communicatively coupled to the application server 184 via the IP interface 125. The application server 184 can also be configured to support one or more communication services (e.g., a Voice over Internet Protocol (VoIP) session, a Push-to-Talk (PTT) session, a group communication session, a social networking service, etc.) for the UEs 101 and 102 via the CN 120.

[0028] P-GW 123 may further be a node for policy enforcement and charging data collection. The Policy and Charging Rules Function (PCRF) 126 is the policy and charging control element of the CN 120. In a non-roaming scenario, in some embodiments, there may be a single PCRF in the Home Public Land Mobile Network (HPLMN) associated with the Internet Protocol connectivity access network (IP-CAN) session of the UE. In a roaming scenario using traffic local breakout, there may be two PCRFs associated with the UE's IP-CAN session: a Home PCRF (H-PCRF) within the HPLMN and a Visited PCRF (V-PCRF) within the Visited Public Land Mobile Network (VPLMN). The PCRF 126 may be communicatively coupled to the application server 184 via the P-GW 123.

[0029] In some embodiments, the communication network 140A can be an IoT network or a 5G network including a 5G New Radio network that uses communications in licensed (5G NR) and unlicensed (5G NR-U) spectrums. One of the current enablers of IoT is Narrowband IoT (NB-IoT).

[0030] The NG system architecture can include the RAN 110 and the 5G Network Core (5GC) 120. The NG-RAN 110 can include multiple nodes such as gNBs and NG-eNBs. The core network 120 (e.g., a 5G core network or 5GC) can include an Access and Mobility Management Function (AMF) and / or a User Plane Function (UPF). The AMF and UPF can be communicatively coupled to the gNBs and NG-eNBs via the NG interface. More specifically, in some embodiments, the gNBs and NG-eNBs can be connected to the AMF by the NG-C interface and to the UPF by the NG-U interface. The gNBs and NG-eNBs can be coupled to each other via the Xn interface.

[0031] In some embodiments, the NG system architecture can use reference points between various nodes as provided by 3GPP Technical Specification (TS) 23.501 (e.g., V15.4.0, December 2018). In some embodiments, each of the gNB and the NG-eNB can be implemented as a base station, a mobile edge server, a small cell, a home eNB, etc. In some embodiments, the gNB can be a master node (MN) in the 5G architecture, and the NG-eNB can be a secondary node (SN).

[0032] Figure 1B shows a non-roaming 5G system architecture according to some embodiments. Referring to Figure 1B, a 5G system architecture 140B is shown in a reference point representation. More specifically, the UE 102 can communicate with the RAN 110 as well as one or more other 5G Core (5GC) network entities. The 5G system architecture 140B includes a plurality of network functions (NFs) such as an Access and Mobility Management Function (AMF) 132, a Session Management Function (SMF) 136, a Policy Control Function (PCF) 148, an Application Function (AF) 150, a User Plane Function (UPF) 134, a Network Slice Selection Function (NSSF) 142, an Authentication Server Function (AUSF) 144, and an Integrated Data Management (UDM) / Home Subscriber Server (HSS) 146. UPF 134 can provide a connection to the data network (DN) 152, which can include, for example, operator services, Internet access, or third-party services. AMF 132 can be used to manage access control and mobility and can also include a network slice selection function. SMF 136 can be configured to set up and manage various sessions according to network policies. UPF 134 can be deployed in one or more configurations according to the desired service type. PCF 148 can be configured to provide a policy framework using network slicing, mobility management, and roaming (similar to PCRF in a 4G communication system). The UDM can be configured to store subscriber profiles and data (similar to HSS in a 4G communication system).

[0033] In some embodiments, the 5G system architecture 140B includes an IP Multimedia Subsystem (IMS) 168B and a plurality of IP multimedia core network subsystem entities such as a Call Session Control Function (CSCF). More specifically, the IMS 168B includes a CSCF, which can function as a Proxy CSCF (P-CSCF) 162BE, a Serving CSCF (S-CSCF) 164B, an Emergency CSCF (E-CSCF) (not shown in FIG. 1B), or an Interrogating CSCF (I-CSCF) 166B. The P-CSCF 162B can be configured to be the first point of contact for the UE 102 within the IP Multimedia Subsystem (IMS) 168B. The S-CSCF 164B can be configured to handle session states in the network, and the E-CSCF can be configured to handle certain embodiments of emergency sessions such as routing emergency requests to the correct emergency center or PSAP. The I-CSCF 166B can be configured to function as a point of contact within the operator's network for all IMS connections destined for subscribers of the network operator or roaming subscribers currently located within the service area of that network operator. In some embodiments, the I-CSCF 166B can connect to another IP multimedia network 170E, for example, an IMS operated by a different network operator.

[0034] In some embodiments, the UDM / HSS 146 can be coupled to an Application Server 160E, which can include a Telephony Application Server (TAS) or another Application Server (AS). The AS 160B can be coupled to the IMS 168B via the S-CSCF 164B or the I-CSCF 166B.

[0035] The reference point representation indicates that interactions can exist between the corresponding NF services. For example, FIG. 1B shows the following reference points: N1 (between UE 102 and AMF 132), N2 (between RAN 110 and AMF 132), N3 (between RAN 110 and UPF 134), N4 (between SMF 136 and UPF 134), N5 (between PCF 148 and AF 150 (not shown)), N6 (between UPF 134 and DN 152), N7 (between SMF 136 and PCF 148 (not shown)), N8 (between UDM 146 and AMF 132 (not shown)), N9 (between two UPFs 134 (not shown)), N10 (between UDM 146 and SMF 136 (not shown)), N11 (between AMF 132 and SMF 136 (not shown)), N12 (between AUSF 144 and AMF 132 (not shown)), N13 (between AUSF 144 and UDM 146 (not shown)), N14 (between two AMF 132s (not shown)), N15 (between PCF 148 and AMF 132 in a non-roaming scenario or between PCF 148 and the visited network and AMF 132 in a roaming scenario (not shown)), N16 (between two SMFs (not shown)), and N22 (between AMF 132 and NSSF 142 (not shown)). Other reference point representations not shown in FIG. 1B can also be used.

[0036] FIG. 1C shows the 5G system architecture 140C and service-based representation. In addition to the network entities shown in FIG. 1B, the system architecture 140C can also include a Network Exposure Function (NEF) 154 and a Network Repository Function (NRF) 156. In some embodiments, the 5G system architecture can be service-based, and the interactions between network functions can be represented by the corresponding point-to-point reference points Ni or as service-based interfaces.

[0037] In some embodiments, as shown in FIG. 1C, the service-based representation can be used to represent network functions within the control plane that enable other authorized network functions to access those services. In this regard, the 5G system architecture 140C can include the following service-based interfaces: Namf 158H (service-based interface presented by AMF 132), Nsmf 158I (service-based interface presented by SMF 136), Nnef 158B (service-based interface presented by NEF 154), Npcf 158D (service-based interface presented by PCF 148), Nudm 158E (service-based interface presented by UDM 146), Naf 158F (service-based interface presented by AF 150), Nnrf 158C (service-based interface presented by NRF 156), Nnssf 158A (service-based interface presented by NSSF 142), Nausf 158G (service-based interface presented by AUSF 144). Other service-based interfaces not shown in FIG. 1C (e.g., Nudr, N5g-eir, and Nudsf) can also be used.

[0038] In some embodiments, any of the UEs or base stations described in connection with FIGS. 1A - 1C can be configured to perform the functions described herein.

[0039] Mobile communications have evolved significantly from the early voice systems to today's highly sophisticated integrated communication platforms. 5G, or New Radio (NR), the next-generation wireless communication system, provides access to information and sharing of data anywhere and anytime for various users and applications. NR is expected to be an integrated network / system that aims to meet significantly different and sometimes conflicting performance dimensions and services. Such diverse multi-dimensional requirements are driven by different services and applications. Generally, NR is based on 3GPP LTE Advanced and is evolving with additional potential new radio access technologies (RATs) to enrich people's lives with better, simpler, and seamless wireless connectivity solutions. NR enables everything to be wirelessly connected and provides high-speed and rich content and services.

[0040] The Rel-15 NR system is designed to operate on licensed spectrum. NR Unlicensed (NR-U), an abbreviation for NR-based access in unlicensed spectrum, is a technology that enables the operation of NR systems on unlicensed spectrum.

[0041] FIG. 2 shows a functional block diagram of a wireless communication device according to some embodiments. The wireless communication device 200 may be suitable for use as a UE or gNB configured for operation in a 5G NR network.

The communication circuit 202 may include circuits that can operate physical layer (PHY) communication and / or media access control (MAC) communication that controls access to the wireless medium, and / or any other communication layer that transmits and receives signals. The communication device 200 may also include a processing circuit 206 and a memory 208 arranged to perform a plurality of operations described herein. In some embodiments, the communication circuit 202 and the processing circuit 206 may be configured to perform the operations detailed in the above figures, drawings, and flows.

The memory 208 may store information for configuring the processing circuit 206, construct and transmit a plurality of message frames, and perform a plurality of operations for performing the various operations described herein. The memory 208 may include any type of memory including non-transitory memory that stores information in a form readable by a machine (e.g., a computer). For example, the memory 208 may include computer-readable storage devices, read-only memory (ROM), random access memory (RAM), magnetic disk storage media, optical storage media, flash memory devices, and other storage devices and media.

[0044] In some embodiments, communication device 200 may be part of a portable wireless communication device such as a personal digital assistant (PDA), a laptop or portable computer with wireless communication capabilities, a web tablet, a wireless phone, a smartphone, a wireless headset, a pager, an instant messaging device, a digital camera, an access point, a television, a medical device (e.g., a heart rate monitor, a blood pressure monitor, etc.), a wearable computer device, or another device capable of receiving and / or transmitting information wirelessly.

[0045] In some embodiments, communication device 200 may include one or more antennas 201. The antennas 201 may include one or more directional or omnidirectional antennas including, for example, dipole antennas, monopole antennas, patch antennas, loop antennas, microstrip antennas, or other types of antennas suitable for transmitting RF signals. In some embodiments, instead of two or more antennas, a single antenna having multiple apertures may be used. In these embodiments, each aperture may be considered a separate antenna. In some multiple-input multiple-output (MIMO) embodiments, the antennas may be effectively separated for spatial diversity and different channel characteristics that may be provided between each of the antennas and the antennas of the transmitting device.

[0046] In some embodiments, communication device 200 may include one or more of a keyboard, a display, a non-volatile memory port, multiple antennas, a graphics processor, an application processor, a speaker, and other mobile device elements. The display may be an LCD screen including a touch screen.

[0047] Although communication device 200 is shown as having several distinct functional elements, two or more of those functional elements may be combined and implemented by a plurality of software-configured elements such as multiple processing elements including multiple digital signal processors (DSPs), and / or by multiple combinations of other multiple hardware elements. For example, some elements may include one or more microprocessors, DSPs, field programmable gate arrays (FPGAs), application specific integrated circuits (ASICs), radio frequency integrated circuits (RFICs), and combinations of various hardware and logic circuits that perform at least the functions described herein. In some embodiments, the plurality of functional elements of communication device 200 may refer to one or more processes operating on one or more processing elements.

[0048] The embodiments disclosed herein relate to enhanced NR measurement gaps (MGs). Some embodiments relate to pre-configured MG patterns, including high-speed MG configurations that include RRM requirements for the pre-configured MG patterns. The embodiments disclosed herein also relate to mechanisms for activation / deactivation of MGs following DCI or timer-based BWP switching (e.g., for each BWP MG configuration). The embodiments disclosed herein also relate to rules and UE behavior specifications for activation / deactivation of MGs following DCI or timer-based BWP switching. The embodiments disclosed herein also relate to defining measurement period requirements with pre-configured MG patterns when there are one or more BWP switches per measurement period.

[0049] FIG. 3A shows measurement report delay without switching of the measurement gap activation status, according to some embodiments. FIG. 3B shows measurement report delay with switching of the measurement gap activation status, according to some embodiments.

[0050] As shown in FIGS. 3A and 3B, a user equipment (UE) configured for operation in a fifth generation new radio (5G NR) network may perform synchronization signal block (SSB)-based radio resource management (RRM) measurements regardless of the presence or absence of a measurement gap 314. The UE may decode network signaling (either network signaling 304 or 306) that triggers a change in the status of a preconfigured measurement gap 311. The UE may perform SSB-based RRM measurements 316 with a measurement gap when network signaling 304 that triggers a change in the status of the preconfigured measurement gap activates the preconfigured measurement gap 311. In these embodiments, the UE may deactivate the preconfigured measurement gap and perform SSB-based RRM measurements 314 without a measurement gap when network signaling 306 that triggers a change in the status of the preconfigured measurement gap deactivates the preconfigured measurement gap 311. In these embodiments, the UE may also encode a measurement report 310 for transmission to the network. The measurement report may include measurement results from SSB-based RRM measurements performed during a measurement report delay period 308. In these embodiments, the number of samples of SSB-based RRM measurements included in the measurement report may be at least partially based on a change in the measurement gap status triggered during the measurement report delay period 308.

[0051] In some embodiments, the network signaling that triggers a change in the status of the pre-configured measurement gap 311 may comprise a switch of the gap activation status. In these embodiments, the UE may determine the length of the measurement reporting delay period 308 depending on whether a switch of the gap activation status has occurred during the measurement reporting delay period 308. In these embodiments, the number of samples of the SSB-based RRM measurement included in the measurement reporting delay period 308 may be based on whether a switch of the gap activation status (i.e., the change in the MG status is triggered) has occurred during the measurement reporting delay period 308. Thus, the length of the measurement reporting delay period 308 may depend on whether a switch of the gap activation status has occurred during the measurement reporting delay period 308 (i.e., when the UE has decided to report the result).

[0052] In some embodiments, the network signaling (either network signaling 304 or 306) that triggers a change in the status of the pre-configured measurement gap 311 may comprise a Downlink Control Information (DCI) format, but the scope of the embodiments is not limited in this regard.

[0053] In some embodiments, the UE may also be configured to decode the Radio-Resource Control (RRC) signaling 302 to configure the UE with the pre-configured measurement gap configuration for performing the SSB-based RRM measurement 316 with the pre-configured measurement gap 311. In these embodiments, the RRC signaling 302 may be received before the network signaling 304 that first activates the pre-configured measurement gap 311.

[0054] In some embodiments, the start of the measurement reporting delay period 308 begins after the network signaling 304 that first activates the preconfigured measurement gap 311. In these embodiments, the measurement reporting delay period 308 may begin at the first measurement gap after the network signaling 304. As shown in FIGS. 3A and 3B, the measurement reporting delay period 308 begins at time 307 with a preconfigured measurement gap 316 and ends at time 310. In some other embodiments, the start of the measurement reporting delay period 308 begins after a Bandwidth Part (BWP) switch, but the scope of the embodiments is not limited in this regard.

[0055] In some embodiments, the UE may refrain from transmitting measurement results from any SSB-based RRM measurements taken before receiving the network signaling 304 that first activates the preconfigured measurement gap 311. In these embodiments, SSB-based RRM measurement values that occurred before activation (i.e., before receiving the network signaling 304) are not reported.

[0056] In some embodiments, when a change in the status of the preconfigured measurement gap 311 (e.g., a change in the measurement gap status) is not triggered during the measurement reporting delay period 308, the number of samples of SSB-based RRM measurements taken during the measurement reporting delay period 308 may be based on one (i.e., either) of the inter-frequency measurement period requirement per sample and the intra-frequency measurement period requirement per sample. In these embodiments, the inter-frequency measurement period requirement per sample and the intra-frequency measurement period requirement per sample may comply with 3GPP TS38.133, but the scope of the embodiments is not limited in this regard.

[0057] In some embodiments, when a change in the status of a pre-configured measurement gap 311 (e.g., a change in the measurement gap status) is triggered during the measurement reporting delay period 308, the number of samples of SSB-based RRM measurements taken during the measurement reporting delay period 308 can be determined based on: at least one of the product of the inter-frequency measurement requirements per sample and the number of inter-frequency measurement samples (i.e., N); the product of the intra-frequency measurement requirements per sample and the number of intra-frequency measurement samples (i.e., M), plus any additional samples based on the transition time for each change in the measurement gap status (i.e., K * transition time), although the scope of the embodiments is not limited in this regard.

[0058] In these embodiments, the number of inter-frequency measurement samples (i.e., N) and the number of intra-frequency measurement samples (i.e., M) include samples from SSB-based RRM measurements with a measurement gap 316 and SSB-based RRM measurements without a measurement gap 314 (i.e., gapless measurements and gap-based measurements) up to a maximum predetermined number of samples (i.e., N + M < 5). In these embodiments, the number of samples of SSB-based RRM measurements taken during the measurement reporting delay period 308 can be determined based on the intra-frequency measurement requirements of TS38.133 per sample * N + the inter-frequency measurement requirements of TS38.133 per sample * M + K * transition time, where N + M is the total number of gapless measurements and gap-based measurements during the measurement reporting period, N + M < 5, and K is the number of changes in the measurement gap status during the measurement reporting delay period 308.

[0059] In some embodiments, when a change in the status of a pre-configured measurement gap 311 (e.g., a change in the measurement gap status) is triggered during the measurement reporting delay period 308, the number of samples of SSB-based RRM measurements taken during the measurement reporting delay period 308 can be determined based on multiplying the maximum values of the inter-frequency measurement requirements per sample and the intra-frequency measurement requirements per sample by a predetermined number of samples (e.g., 5), and adding any additional samples based on the transition time for each change in the measurement gap status (i.e., K * transition time), although the scope of the embodiments is not limited in this regard. In these embodiments, when a change in the measurement gap status is triggered during the measurement reporting delay period 308, the number of samples of SSB-based RRM measurements taken during the measurement reporting delay period 308 can be based on the maximum value {intra-frequency measurement requirements at 38.133 per sample, inter-frequency measurement requirements at 38.133 per sample} * 5 + K * transition time.

[0060] In some embodiments, in response to receiving network signaling 304 that triggers a change in the pre-configured measurement gap status that activates the pre-configured measurement gap 311, the UE may perform SSB-based RRM measurements 316 with a measurement gap and refrain from performing SSB-based RRM measurements without a measurement gap. In these embodiments, in response to receiving network signaling 306 that triggers a change in the pre-configured measurement gap status that deactivates the pre-configured measurement gap 311, the UE may perform SSB-based RRM measurements 314 without a measurement gap and refrain from performing SSB-based RRM measurements with a measurement gap.

[0061] In some embodiments, the SSB-based RRM measurement may comprise measurement of one or more reference signals between SSB blocks 312 (i.e., SS / PBCH blocks) by a UE in an RRC connected state in which intra-frequency cells and / or inter-frequency cells and / or inter-RAT E-UTRAN cells can be identified and measured. During measurement gap 311, the UE is not scheduled to receive data from its serving cell and may be able to switch to another carrier to perform SSB-based RRM measurements.

[0062] Some embodiments are directed to a non-transitory computer-readable storage medium storing instructions for execution by a processing circuit of a user equipment (UE) configured for operation in a fifth generation new radio (5G NR) network. In these embodiments, the processing circuit may configure the UE to perform synchronization signal block (SSB)-based radio resource management (RRM) measurements without a measurement gap 314. The processing circuit may also configure the UE to decode network signaling (either network signaling 304 or 306) that triggers a change in the status of a pre-configured measurement gap 311. The UE may perform SSB-based RRM measurements 316 with a measurement gap when network signaling 304 that triggered a change in the pre-configured measurement gap status activates the pre-configured measurement gap 311. The UE may also deactivate the pre-configured measurement gap and perform SSB-based RRM measurements 314 without a measurement gap when network signaling 306 that triggered a change in the pre-configured measurement gap status deactivates the pre-configured measurement gap 311. The UE may also encode a measurement report 310 for transmission to the network. In these embodiments, the measurement report may include measurement results from SSB-based RRM measurements performed during a measurement report delay period 308. In these embodiments, the number of samples of SSB-based RRM measurements included in the measurement report may be at least partially based on a change in the measurement gap status triggered during the measurement report delay period 308.

[0063] Some embodiments are directed to a gNodeB (gNB) configured for operation in a 5th generation new radio (5G NR) network. In these embodiments, the gNB may be configured to encode network signaling (either network signaling 304 or 306) for transmission to a user equipment (UE) to trigger a change in the status of a preconfigured measurement gap 311. The gNB may be configured to decode a measurement report 310 received from the UE. In these embodiments, the measurement report may include measurement results from synchronization signal block (SSB)-based radio resource management (RRM) measurements performed by the UE during a measurement report delay period 308. In these embodiments, the number of samples of the SSB-based RRM measurements included in the measurement report may be at least partially based on a change in the measurement gap status triggered during the measurement report delay period 308.

[0064] In some embodiments, UE capabilities for UE measurements with preconfigured gaps in NR are defined. With respect to measurement latency with a preconfigured MG configuration, generally note that the measurement latency with a preconfigured MG starts when the first preconfigured MG is activated. However, as shown in FIG. 3A, there may still be ongoing measurements after the last UE report and before the activated first preconfigured MG. To simplify these requirements, the UE may resume a new measurement process with a new preconfigured MG. In these embodiments, unreported measurement results are reset. In these embodiments, the measurement latency starts from the activation of the first preconfigured MG.

[0065] In one embodiment, regarding the measurement delay with a pre-configured MG, it should be noted that there is no switching of the activation / deactivation status of the pre-configured MG during one successful measurement reporting process (which may include multiple UE measurement samples). In these embodiments, the measurement with a pre-configured MG can be the same as the inter-frequency measurement. On the other hand, if there is a switching of the activation / deactivation status of the pre-configured MG during one successful measurement reporting process, such a measurement process can be divided into two parts, namely, one is the measurement with a pre-configured MG and the other is the measurement without a gap, as shown in Figure 3B. Therefore, the measurement delay can be composed of at least the intra-frequency measurement requirement per sample and the inter-frequency measurement requirement per sample.

[0066] Compared with the measurement with a legacy MG, the measurement with a pre-configured MG may require more time due to gap transitions. In these embodiments, the measurement delay with a pre-configured MG can be defined as depending on whether there is a change in the activation / deactivation status within the measurement reporting period. This is shown in the following table.

Table 1

[0067] In some alternative embodiments, for the sake of simplicity, these requirements can be defined for a scenario where no switching of any pre-configured MG status occurs. Based on this assumption, when a new pre-configured MG is used for the measurement after BWP switching, since the measurement procedure starts from the first gap after BWP switching, the measurement delay itself is no different from other legacy gaps. There is almost no impact on the measurement minimum performance requirements (such as cell detection delay, measurement period, etc.). Therefore, the measurement delay requirement can be the same as the intra-frequency measurement with scheduling limitations.

[0068] In some embodiments, measurements with preconfigured MGs may comply with those for inter-frequency SSB / CSI-RS measurement requirements. In these embodiments, the total measurement requirements may be defined by the maximum of the per-sample intra-frequency measurement requirements and the per-sample inter-frequency measurement requirements. This is shown in the following table.

Table 2

[0069] In some embodiments, the measurement delay requirements are defined for preconfigured gap-based measurements. In some embodiments, the starting point of the measurement delay can be the first preconfigured gap that is activated. In some embodiments, the measurement delay with preconfigured MGs can be defined depending on whether there is an activated / deactivated status change during the measurement period. In some embodiments, if there is no switching of the preconfigured gap activation status during the UE measurement reporting period, the delay can be based on the inter-frequency measurement requirements in TS38.133. In some embodiments, if there is a switching of the preconfigured gap activation status during the UE measurement reporting period, the delay can be based on both the inter-frequency measurement requirements and the intra-frequency measurement requirements in TS38.133. In some embodiments, if there is a switching of the preconfigured gap activation status during the UE measurement reporting period, the delay can be based on the maximum value {inter-frequency measurement requirements per sample, intra-frequency measurement requirements per sample} as defined in TS38.133. In some embodiments, if there is a switching of a certain preconfigured gap activation status during the UE measurement reporting period, the delay can be based on only the inter-frequency measurement requirements per sample.

[0070] In some embodiments, the measurement report delay may be defined as the time between the event that triggers the measurement report and the time when the UE starts transmitting the measurement report via the air interface. This requirement assumes that the measurement report is not delayed by other RRC signaling on the DCCH. This measurement report delay excludes the delay uncertainty that occurs when inserting the measurement report into the TTI of the uplink DCCH. The delay uncertainty is: 2xTTI DCCH is. This measurement report delay excludes the delay caused by the non-existence of UL resources available for the UE to transmit the measurement report.

[0071] The event-triggered measurement report delay measured without L3 filtering is T identify intra with index or T identify intra without index shall be smaller than. When L3 filtering is used, additional delay may be expected. In EN-DC and NE-DC operations, when the UE is configured to perform E-UTRA SRS carrier-based switching, if the UE can handle the gap for each FR, additional delay may be expected in FR1, or if the UE cannot handle the gap for each FR, additional delay may be expected in both FR1 and FR2.

[0072] The cell is detectable only if at least one SSB measured from the configured cell remains detectable during the period T identify_intra_without_index or T identify_intra_with_index At least the period T identify intra without index or T identify intra with indexIf a cell that was detectable at μ becomes undetectable within a period of ≤ 5 seconds and then becomes detectable again with the same spatial reception parameters, triggering an event, the timing to the cell is ±3200 / 2 while the measurement gap is not available and L3 filtering is not used, provided that the change does not exceed T SSB_measurement_period_intra c. The event-triggered measurement report delay is considered to be less than T, where μ is the SCS configuration. When L3 filtering is used, additional delay may be expected.

[0073] Measurements are defined as SSB-based in-band measurements as long as the center frequencies of the SSBs of the serving cell and the neighboring cells shown for measurement are the same and the subcarrier spacing of the two SSBs is also the same. If carrier frequency information is provided by the PCell or PSCell, the UE shall be able to identify new in-band cells and perform SS-RSRP, SS-RSRQ, and SS-SINR measurements of the identified in-band cells even if no explicit neighbor list with physical layer cell identification information is provided. For in-band measurements, if the UE indicates "no gap" via intraFreq-needForGap, or if the SSB is fully included in the UE's active BWP, or if the active downlink BWP is the initial BWP, the UE may perform in-band SSB-based measurements without a measurement gap (either a legacy measurement gap or an NCSG).

[0074] When a measurement gap is provided, or when an activated Pre-MG is provided without any change in the Pre-MG status during the measurement period, if the UE is not signaled to report SSB-based RRM measurement results with associated SSB indexes (reportQuantityRsIndexes or maxNrofRSIndexesToReport is not configured), or if the UE is signaled that the neighboring cells are synchronized with the serving cell (deriveSSB-IndexFromCell is enabled), the UE shall be able to identify new detectable in-band cells within T identify_intra_without_index assuming that it can identify new detectable in-band cells within T identify_intra_with_index otherwise, the UE shall be able to identify new detectable in-band cells within T identify_intra_without_index The UE shall be able to identify new detectable in-band SS blocks of cells that have already been detected within T. deriveSSB-IndexFromCell is assumed to be always enabled for FR1 TDD and FR2.

[0075] T identify_intra_without_index = T PSS / SSS_sync_intra + T SSB_measurement_period_intra milliseconds

[0076] T identify_intra_with_index = T PSS / SSS_sync_ntra + T SSB_measurement_period_intra + T SSB_time_index_intra milliseconds

[0077] where: T PSS / SSS_sync_intra : It is the period used in PSS / SSS detection as presented in Table 9.2.6.2-1 or 9.2.6.2-2, T SSB_time_index_intra : It is the period used to obtain the index of the measured SSB as presented in Table 9.2.6.2-3, T SSB_measurement_period_intra : CSSF equal to the measurement period of the SSB-based measurement as presented in Table 9.2.6.3-1, 9.2.6.3-2 intra : It is the carrier-specific scaling factor, and for the measurements performed within the measurement gap, it is determined according to CSSF within_gap,i and Kgap is the scaling factor of the SSB frequency layer measured within the associated measurement gap pattern. When the UE is not configured with a simultaneous measurement gap or does not support [simultaneous measurement gap], K gap = 1.

[0078] When a measurement gap is provided, or when an activated Pre-MG is provided without any change in the Pre-MG status during the measurement period, the measurement period for in-band measurement within FR1 frequencies with gaps is as shown in Table 9.2.6.3-1, and the measurement period for in-band measurement within FR2 frequencies with gaps is as shown in Table 9.2.6.3-2.

Table 4

[0082] Intra-frequency adjacent (cell) measurement and inter-frequency adjacent (cell) measurement are defined as follows: SSB-based intra-frequency measurement: The measurement is defined as an SSB-based intra-frequency measurement as long as the center frequency of the SSB of the serving cell and the center frequency of the SSB of the adjacent cell are the same and the subcarrier spacing of the two SSBs is also the same. SSB-based inter-frequency measurement: The measurement is defined as an SSB-based inter-frequency measurement as long as the center frequency of the SSB of the serving cell and the center frequency of the SSB of the adjacent cell are different or the subcarrier spacing of the two SSBs is different.

[0083] Whether the measurement is non-gap-assisted or gap-assisted depends on the UE's capabilities, the UE's active BWP, and the current operating frequency. For SSB-based inter-frequency measurements, if the measurement gap requirement information is reported by the UE, the measurement gap configuration can be provided in accordance with that information. Otherwise, the measurement gap configuration is always provided in the following cases: when the UE supports only UE-specific measurement gaps; when the UE supports FR-specific measurement gaps and any of the serving cells is within the same frequency range as the measurement target.

[0084] For in-SSB frequency measurements, if the measurement gap requirement information is reported by the UE, the measurement gap configuration can be provided in accordance with that information. Otherwise, the measurement gap configuration is always provided in the following cases. When any of the BWPs according to the UE configuration, other than the initial BWP, does not include the frequency-domain resources of the SSB associated with the initial DL BWP. In a non-gap-assisted scenario, it is assumed that the UE can perform such measurements without a measurement gap. In a gap-assisted scenario, it cannot be assumed that the UE can perform such measurements without a measurement gap.

[0085] In some embodiments, the number of samples included in the measurement report can be determined by the UE based on reliability (i.e., being sufficient to meet the reliability requirements), but the scope of the embodiments is not limited in this regard. In some embodiments, the UE may send a "needs for gap" information element to the network when a measurement gap configuration is required to perform a measurement.
