AI Technical Summary
The conflict between low power wakeup radio (LP-WUR) operation and early measurement report (EMR) configuration in user equipment (UE) leads to inefficiencies in radio resource management (RRM) measurements, particularly when the UE is in Idle or Inactive mode, as LP-WUR cannot perform neighbor cell measurements.
The UE is configured to offload serving cell RRM measurements from the main radio (MR) to a low power wakeup radio (LP-WUR) based on serving cell RRM measurements, using a T331 timer configuration and determining the type of RRM measurements to be performed by the MR based on signaling from the base station.
This solution allows the UE to efficiently manage RRM measurements by coordinating the operations of the MR and LP-WUR, optimizing power consumption and measurement performance in various scenarios, ensuring timely and accurate reporting of neighbor cell measurements.

Abstract
Description
Low Power-Wakeup Radio Based RRM with Early Measurement ReportingBackground
[0001] A user equipment (UE) may be configured with carrier aggregation (CA) side where the UE is served by multiple serving cells. In some scenarios, the network may configure the UE to perform early measurement reports (EMR) for Radio Resource Management (RRM) measurements. This EMR configuration may include an EMR list of candidate CA carriers to be measured when the UE is in the Radio Resource Control (RRC) Idle mode or Inactive mode that are then reported when the UE transitions to RRC Connected mode. This may speed up the network selection of carriers for CA.
[0002] However, when the UE is in the Idle or Inactive mode, the UE may be using a low power wakeup radio (LP-WUR) instead of the main radio. The LP-WUR may only have the capability to measure the current serving cell. This may lead to a conflict between LP-WUR operation and the EMR configuration.Summary
[0003] Some example embodiments are related to an apparatus having processing circuitry configured to process, based on signaling from a base station, an early measurement report (EMR) configuration comprising an EMR list of one or more neighbor cells or carriers for which radio resource management (RRM) measurements to be performed by a main radio (MR) when in a radio resource control (RRC) Idle mode or Inactive mode, wherein the EMR configuration further comprises a T331 timer configuration and process, based on signaling received from the base station, an MR configuration to offload serving cell RRM measurements from the MR to a low power wakeup radio (LR) based on serving cell RRM measurements.
[0004] Other example embodiments are related to an apparatus having processing circuitry configured to process, based on signaling from a base station, an early measurement report (EMR) configuration comprising an EMR list of one or more neighbor cells or carriers for which radio resource management (RRM) measurements to be performed by a main radio (MR) when in a radio resource control (RRC) Idle mode or Inactive mode and process, based on signaling received from the base station, an MR configuration to offload serving cell RRM measurements from the MR to a low power wakeup radio (LR) based on serving cell RRM measurements.
[0005] Still further example embodiments are related to an apparatus having processing circuitry configured to generate, for transmission to a user equipment (UE) , an early measurement report (EMR) configuration comprising an EMR list of one or more neighbor cells or carriers for which radio resource management (RRM) measurements to be performed by a main radio (MR) of the UE when in a radio resource control (RRC) Idle mode or Inactive mode, wherein the EMR configuration further comprises a T331 timer configuration and process, based on signaling received from the UE, an EMR comprising results for the RRM measurements on the one or more neighbor cells or carriers of the EMR list.Brief Description of the Drawings

[0011] The example embodiments may be further understood with reference to the following description and the related appended drawings, wherein like elements are provided with the same reference numerals. The example embodiments relate to scenarios where a user equipment (UE) is configured with early measurement reports (EMR) for Radio Resource Management (RRM) measurements and with a low power wakeup radio (LP-WUR) configuration where a main radio (MR) of the UE may be turned to an off state. The example embodiments provide operations to resolve the conflict between the EMR configuration and the LP-WUR configuration.
[0012] The example embodiments are described with regard to a UE. However, reference to a UE is merely provided for illustrative purposes. The example embodiments may be utilized with any electronic component that may establish a connection to an accessory device and is configured with the hardware, software, and / or firmware to exchange information and data with accessory devices. Therefore, the UE as described herein is used to represent any electronic component.
[0013] The example embodiments are also described with reference to a 5G New Radio (NR) network. However, the example embodiments may also be implemented in other types of networks, including but not limited to LTE networks, future evolutions of the cellular protocol (e.g., 5G-advanced networks, 6G networks, etc. ) , or any other type of network.
[0014] The example embodiments are further described with carrier aggregation (CA) and dual connectivity (DC) mechanisms where multiple carriers may serve the UE. In CA and DC, The UE may be configured with a primary cell group (PCG) and a secondary cell group (SCG) . The PCG may include a primary cell (PCell) and one or more secondary cells (SCells) for communication between the UE and the network. The PCell serves a primary component carrier (PCC) and the SCells serve one or more secondary component carriers (SCCs) . In addition, the SCG may include a primary secondary cell (PSCell) and one or more SCells for communication between the UE and the network. The PSCell serves a primary secondary component carrier (PSCC) and the SCells serve one or more SCCs.
[0015] The example embodiments relate to scenarios where a UE is configured with conflicting EMR and LP-WUR configurations. The example embodiments provide operations to allow the UE to determine whether a main radio (MR) of the UE should be in an on state or an off state when the UE has the conflicting configurations. In addition, the operations may also allow the UE to determine the type of RRM measurements to be performed when the MR is in the on state. The type of measurements may include serving cell measurements, neighbor cell or carrier measurements that are on an EMR list and other neighbor cell or carrier measurements that are not on the EMR list. The RRM measurements may also be performed using a relaxation mode. Each of these example embodiments will be described in greater detail below.
[0016] Fig. 1 shows an example network arrangement 100 according to various example embodiments. The example network arrangement 100 includes a UE 110. The UE 110 may be any type of electronic component that is configured to communicate via a network, e.g., mobile phones, tablet computers, desktop computers, smartphones, embedded devices, wearables, Internet of Things (IoT) devices, etc. An actual network arrangement may include any number of UEs being used by any number of users. Thus, the example of one UE 110 is merely provided for illustrative purposes.
[0017] The UE 110 may be configured to communicate with one or more networks. In the example of the network arrangement 100, the network with which the UE 110 may wirelessly communicate is a 5G NR radio access network (RAN) 120. The UE 110 may also communicate with other types of networks (e.g., 5G cloud RAN, a next generation RAN (NG-RAN) , a legacy cellular network, etc. ) and the UE 110 may also communicate with networks over a wired connection. With regard to the example embodiments, the UE 110 may establish a connection with the 5G NR RAN 120. Therefore, the UE 110 may have a 5G NR chipset to communicate with the NR RAN 120.
[0018] The 5G NR RAN 120 may be portions of a cellular network that may be deployed by a network carrier (e.g., Verizon, AT&T, T-Mobile, etc. ) . The RAN 120 may include cells or base stations that are configured to send and receive traffic from UEs that are equipped with the appropriate cellular chip set. In this example, the 5G NR RAN 120 includes the gNB 120A and the gNB 120B. However, reference to a gNB is merely provided for illustrative purposes, any appropriate base station or cell may be deployed (e.g., Node Bs, eNodeBs, HeNBs, eNBs, gNBs, gNodeBs, macrocells, microcells, small cells, femtocells, etc. ) .
[0019] Any association procedure may be performed for the UE 110 to connect to the 5G NR RAN 120. For example, as discussed above, the 5G NR RAN 120 may be associated with a particular network carrier where the UE 110 and / or the user thereof has a contract and credential information (e.g., stored on a SIM card) . Upon detecting the presence of the 5G NR RAN 120, the UE 110 may transmit the corresponding credential information to associate with the 5G NR RAN 120. More specifically, the UE 110 may associate with a specific cell (e.g., gNB 120A) .
[0020] The network arrangement 100 also includes a cellular core network 130, the Internet 140, an IP Multimedia Subsystem (IMS) 150, and a network services backbone 160. The cellular core network 130 manages the traffic that flows between the cellular network and the Internet 140. The IMS 150 may be generally described as an architecture for delivering multimedia services to the UE 110 using the IP protocol. The IMS 150 may communicate with the cellular core network 130 and the Internet 140 to provide the multimedia services to the UE 110. The network services backbone 160 is in communication either directly or indirectly with the Internet 140 and the cellular core network 130. The network services backbone 160 may be generally described as a set of components (e.g., servers, network storage arrangements, etc. ) that implement a suite of services that may be used to extend the functionalities of the UE 110 in communication with the various networks.
[0021] Fig. 2 shows an example UE 110 according to various example embodiments. The UE 110 will be described with regard to the network arrangement 100 of Fig. 1. The UE 110 may represent any electronic device and may include a processor 205, a memory arrangement 210, a display device 215, an input / output (I / O) device 220, a transceiver 225, and other components 230. The other components 230 may include, for example, an audio input device, an audio output device, a battery that provides a limited power supply, a data acquisition device, ports to electrically connect the UE 110 to other electronic devices, sensors to detect conditions of the UE 110, etc.
[0022] The processor 205 may be configured to execute a plurality of engines for the UE 110. For example, the engines may include an EMR engine 235 for performing operations related to performing EMR RRM measurements. The operations include, but are not limited to, determining whether to offload serving cell measurements from an MR to an LP-WUR, determining whether to place the MR in a on state or an off state, and determining the type of RRM measurements to perform when in the on state. Each of these example operations will be described in more detail below.
[0023] The above referenced engine being an application (e.g., a program) executed by the processor 205 is only example. The functionality associated with the engines may also be represented as a separate incorporated component of the UE 110 or may be a modular component coupled to the UE 110, e.g., an integrated circuit with or without firmware. For example, the integrated circuit may include input circuitry to receive signals and processing circuitry to process the signals and other information. The engines may also be embodied as one application or separate applications. In addition, in some UEs, the functionality described for the processor 205 is split among two or more processors such as a baseband processor and an applications processor. The example embodiments may be implemented in any of these or other configurations of a UE.
[0024] The memory arrangement 210 may be a hardware component configured to store data related to operations performed by the UE 110. The display device 215 may be a hardware component configured to show data to a user while the I / O device 220 may be a hardware component that enables the user to enter inputs. The display device 215 and the I / O device 220 may be separate components or integrated together such as a touchscreen.
[0025] The transceiver 225 may be a hardware component configured to establish a connection with the 5G NR-RAN 120, an LTE-RAN (not pictured) , a legacy RAN (not pictured) , a WLAN (not pictured) , etc. The transceiver 225 may include a main radio (MR) and a low power wakeup radio (LP-WUR) . Accordingly, the transceiver 225 may operate on a variety of different frequencies or channels (e.g., set of consecutive frequencies) . The transceiver 225 includes circuitry configured to transmit and / or receive signals (e.g., control signals, data signals) . Such signals may be encoded with information implementing any one of the methods described herein. The processor 205 may be operably coupled to the transceiver 225 and configured to receive from and / or transmit signals to the transceiver 225. The processor 205 may be configured to encode, decode and / or process signals (e.g., signaling from a base station of a network) for implementing any one of the methods described herein.
[0026] Fig. 3 shows an example base station 300 according to various example embodiments. The base station 300 may represent the gNB 120A or any other access node through which the UE 110 may establish a connection and manage network operations.
[0027] The base station 300 may include a processor 305, a memory arrangement 310, an input / output (I / O) device 315, a transceiver 320, and other components 325. The other components 325 may include, for example, an audio input device, an audio output device, a battery, a data acquisition device, ports to electrically connect the base station 300 to other electronic devices and / or power sources, etc.
[0028] The processor 305 may be configured to execute a plurality of engines for the UE 110. For example, the engines may include an EMR configuration engine 330 for performing operations related to configuring a UE with information related to EMR RRM measurements. The operations include, but are not limited to, configuring the UE with an EMR configuration including an EMR list, wherein the EMR configuration may also include one or more timers and an indication of whether the EMR measurements are required. Each of these example operations will be described in more detail below.
[0029] The memory arrangement 310 may be a hardware component configured to store data related to operations performed by the base station 300. The I / O device 315 may be a hardware component or ports that enable a user to interact with the base station 300. The transceiver 320 may be a hardware component configured to exchange data with the UE 110 and any other UE in the network arrangement 100.
[0030] The transceiver 320 may be a hardware component configured to exchange data with the UE 110 and any other UE in the network arrangement 100. The transceiver 320 may operate on a variety of different frequencies or channels (e.g., set of consecutive frequencies) . The transceiver 320 includes circuitry configured to transmit and / or receive signals (e.g., control signals, data signals) . Such signals may be encoded with information implementing any one of the methods described herein. The processor 305 may be operably coupled to the transceiver 320 and configured to receive from and / or transmit signals to the transceiver 320. The processor 305 may be configured to encode, decode and / or process signals (e.g., signaling from a UE) for implementing any one of the methods described herein.
[0031] As described above, the network may configure the UE to perform EMR for RRM measurements. However, the UE may also be operating using a LP-WUR that cannot perform neighbor cell measurements. This may result in a conflict. The example embodiments provide clarification of UE and network operation during these scenarios.
[0032] Prior to describing the example embodiments, various RRM measurement use cases to which the example embodiments may be applied are described. These use cases are summarized in the table of Fig. 4. Fig. 4 shows a table 400 comprising example use cases according to various example embodiments. The UE and the network are not required to implement each of these use cases. Rather the use cases are provided to show how the example embodiments may be implemented in different scenarios experienced by the network and UE.
[0033] The columns of the table 400 from left to right show the example use case (RRM measurement case index) , the status of the main radio (MR) serving cell measurement, the status of the MR neighbor cell measurements and the status of the LP-WUR (LR) .
[0034] The first example use case is a fully offloaded case. In this use case, the MR is off and the LR is on and performing serving cell measurements.
[0035] The second example use case is a relaxed case a. In this use case, the MR is on for performing serving cell measurements with relaxation. RRM relaxation generally refers to a mode where RRM measurements are performed in one scenario at a lower rate than under another scenario, e.g., a lower rate than during legacy Idle / Inactive mode. In some examples, a first rate is lower than a second rate for legacy measurements in an RRC Idle mode or Inactive mode. The rate of performing legacy Idle / Inactive mode RRM measurements is defined in 3GPP Technical Specification (TS) 38.133 section 4 and section 5. This allows the UE to save power and processing resources. In the second example use case, the MR is not performing neighbor cell measurements and the LR is on and performing serving cell measurements.
[0036] The third example use case is a relaxed case b. In this use case, the MR is on for performing serving cell measurements with relaxation and on for performing neighbor cell measurements with relaxation. The LR is also on and performing serving cell measurements.
[0037] The fourth example use case is a relaxed case c. In this use case, the MR is off for performing serving cell measurements and on for performing neighbor cell measurements with relaxation. The LR is also on and performing serving cell measurements.
[0038] The fifth case is a legacy case where the MR is fully on for serving cell and neighbor cell measurements and the LR is off.
[0039] Fig. 5 shows an example diagram 500 of when the example use cases of the table 400 of Fig. 4 may be applied according to various example embodiments. The diagram 500 shows a serving cell 510 and a UE 520 in various locations relative to the serving cell 510.
[0040] When the UE 520 is in the area 530 relative to the serving cell 510, the UE 520 may be operating in the first example use case, e.g., fully offloaded case where the LR is performing the serving cell measurements and the MR is off. In this scenario, the UE 520 has a good connection to the serving cell 510 and no neighbor cell measurements need to be performed. However, there may be other factors that the UE and / or network consider when determining whether to perform neighbor cell measurements. For example, as described above, in CA / DC operation, the UE may perform neighbor cell measurements even when the serving cell connection is good because these neighbor cells may be added as CA / DC carriers when the UE transitions to RRC Connected mode. These neighbor cell measurements under this type of scenario are described in greater detail below.
[0041] As shown in Fig. 5, the boundary of the area 530 may be the threshold for fully offloading the RRM measurements (e.g., in area 530) . In some example embodiments, this offloading threshold may be the same as the threshold for performing neighbor cell measurements, e.g., based on SIntraSearchP, SIntraSearchQ, SnonIntraSearchP, SnonIntraSearchQ. These thresholds and use of the thresholds are described in greater detail below. This is shown in Fig. 5 as the area 550. In these example embodiments, when the UE 520 is in the area 550, the UE 520 may be operating in the third example use case relaxed case b where the MR is on for serving cell measurements with relaxation and neighbor cell measurements with relaxation and the LR is on for serving cell measurements.
[0042] In other example embodiments, the threshold for fully offloading the RRM measurements may be different than the threshold for performing neighbor cell measurements, e.g., two different thresholds. This is shown in Fig. 5 as the area 540. In these example embodiments, when the UE 520 is in the area 540, the UE 520 may be operating in the second example use case relaxed case a where the MR is on for serving cell measurements with relaxation and off for neighbor cell measurements and the LR is on for serving cell measurements, e.g., the MR is not on for any neighbor cell measurements until the neighbor cell measurement thresholds are satisfied. When the neighbor cell measurement thresholds are satisfied, then the UE 520 may transition to the third example use case.
[0043] When the UE 520 is in the area 560 relative to the serving cell 510, the UE 520 may be operating in the fourth example use case relaxed case c where the MR is off for serving cell measurements and on for neighbor cell measurements with relaxation and the LR is on for serving cell measurements.
[0044] When the UE 520 is in the area 570 relative to the serving cell 510, the UE 520 may be operating in the fifth example use case, the legacy use case where the MR is on for serving cell measurements and neighbor cell measurements and the LR is off.
[0045] The example embodiments provide operations to be performed by the UE and the network to coordinate in the scenario where the UE is configured with both EMR and LP-WUR operations.
[0046] In some example embodiments, the operations performed by the UE may be related to whether a timer (T331) is running for the UE, e.g., as part of the EMR configuration, the network may also configure the T331 timer. The UE may perform RRM measurements while the T331 timer is running for handover purposes, and if the UE does not complete the measurements within the T331 timer duration, the UE may trigger a handover failure. The example embodiments do not alter the operation of the T331 timer and the timer is to operate in accordance with the definitions provided in the 3GPP standards. The following provide some examples of operations based on the status of the T331 timer.
[0047] In some example embodiments, the UE supports idleInactiveNR-MeasReport-r16 or idleInactiveEUTRA-MeasReport-r16 (e.g., the UE supports EMR measurements) , and the network configures carriers for idle mode CA / DC measurement reporting with T331 (e.g., the network configures an EMR list for the UE) and the T331 is currently running, e.g., the EMR configuration is currently valid.
[0048] In a first option, the UE may keep the MR on regardless of whether the MR offloading condition is met. The condition may be, for example, the measurement results of the serving cell meets the enter condition of MR offloading (e.g., the condition to turn off the MR) or the measurement results of the serving cell meets exit condition of MR offloading (e.g., condition to wake up the MR) . In this option, the UE is configured with EMR and the configuration is valid, so the UE may perform the neighbor cell measurements in the EMR list using the MR, regardless of whether the MR offloading condition is met.
[0049] In a second option, the network may indicate that the UE is to keep the MR on or off for this case, e.g., the network may indicate in the EMR configuration that the MR is to be on or off and the UE may determine to follow the network indication or may determine to turn the MR on / off differently than the indication provided by the network. This determination by the UE may be made based on the examples provided below. In this option, there may be two cases based on whether serving cell measurement thresholds are satisfied. The serving cell measurements may be, for example, Srxlev that is a cell selection reception (Rx) level value based on Reference Signal Received Power (RSRP) or a Squal that is a cell selection quality value based on Reference Signal Received Quality (RSRQ) .
[0050] In a first case, a condition may be that the serving cell measurement results satisfy “Srxlev<=SnonIntraSearchP or Squal<=SnonIntraSearchQ, ” e.g., neighbor cell measurement thresholds are satisfied. The definitions of SnonIntraSearchP and SnonIntraSearchQ are provided in 3GPP TS 38.304 and these thresholds are used in the example embodiments consistent with these definitions.
[0051] When this first case condition is satisfied, in some examples, the UE may use the MR to perform serving cell measurements, neighbor cell or carrier measurements in the EMR list and other neighbor cell or carrier measurements with relaxation mode, e.g., at a rate lower than the normal rate defined for Idle / Inactive mode RRM measurements.
[0052] In other examples, when this first case condition is satisfied, the UE may use the MR to perform serving cell measurements and neighbor cell or carrier measurements not in the EMR list with relaxation mode, but the UE may perform neighbor cell or carrier measurements in the EMR list without relaxation mode.
[0053] In a second case, a condition may be that the serving cell measurement results satisfy “Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, ” e.g., neighbor cell measurement thresholds are not satisfied.
[0054] When this second case condition is satisfied, in some examples, the UE may use the MR to perform serving cell measurements with relaxation mode and may perform neighbor cell or carrier measurements in the EMR list and other neighbor cell or carrier measurements the same as higher priority frequency layer measurements with relaxation mode. Higher priority frequency measurement is defined in 3GPP TS38.133 section 4.2.2.7. Thus, in this example, the MR performs neighbor cell or carrier measurements in the EMR list and other neighbor cell or carrier measurements the same as defined for the higher priority frequency layer measurements with relaxation mode.
[0055] In other examples, when this second case condition is satisfied, the UE may use the MR to (1) perform serving cell measurements with relaxation mode, and (2) perform neighbor cell or carrier measurements not in the EMR list with relaxation mode if that carrier is the higher priority frequency layer measurement, but (3) perform neighbor cell or carrier measurements in the EMR list without relaxation mode even if that carrier is a higher priority frequency layer measurement. If the target carrier is a neighbor cell or carrier measurement not in the EMR list and that carrier is not a higher priority frequency layer measurement, the UE may not perform measurements on that target carrier.
[0056] In other example embodiments, the UE supports idleInactiveNR-MeasReport-r16 or idleInactiveEUTRA-MeasReport-r16 (e.g., supports EMR) , and the network configures carriers for idle mode CA / DC measurement reporting with T331 (e.g., UE configured with EMR list) and the T331 is expired. In a first option, the UE may keep the MR on regardless of whether the MR offloading condition is met. The condition may be, for example, the measurement results of the serving cell meets the enter condition of MR offloading (e.g., the condition to turn off the MR) or the measurement results of the serving cell meets exit condition of MR offloading (e.g., condition to wake up the MR) .
[0057] In a second option, the network may indicate that the UE is to keep the MR on or off when the T331 timer has expired, e.g., should the UE continue to perform EMR measurements after the T331 has expired. There may be two scenarios for this option. A first scenario is where the network has indicated that the MR is on, e.g., UE should continue to perform EMR measurements after the T331 timer has expired. In this scenario, there may be two cases based on whether serving cell measurement thresholds are satisfied, e.g., Srxlev and / or Squal thresholds.
[0058] In a first case of the first scenario, a condition may be that the serving cell measurement results satisfy “Srxlev<=SnonIntraSearchP or Squal<=SnonIntraSearchQ, ” e.g., neighbor cell measurement thresholds are satisfied. When this first case condition of the first scenario is satisfied, in some examples, the UE may use the MR to perform serving cell measurements, neighbor cell or carrier measurements in the EMR list and other neighbor cell or carrier measurements with relaxation mode.
[0059] In other examples, when this first case condition of the first scenario is satisfied, the UE may use the MR to perform serving cell measurements and neighbor cell or carrier measurements not in the EMR list with relaxation mode, but the UE may perform neighbor cell or carrier measurements in the EMR list without relaxation mode.
[0060] In a second case of the first scenario, a condition may be that the serving cell measurement results satisfy “Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, ” e.g., neighbor cell measurement thresholds are not satisfied. When this second case condition of the first scenario is satisfied, in some examples, the UE may use the MR to perform serving cell measurements with relaxation mode and may perform neighbor cell or carrier measurements in the EMR list and other neighbor cell or carrier measurements the same as higher priority frequency layer measurements with relaxation mode.
[0061] In other examples, when this condition of the second case of the first scenario is satisfied, the UE may use the MR to (1) perform serving cell measurements with relaxation mode, and (2) perform neighbor cell or carrier measurements not in the EMR list with relaxation mode if that carrier is the higher priority frequency layer measurement, but (3) perform neighbor cell or carrier measurements in the EMR list without relaxation mode even if that carrier is a higher priority frequency layer measurement. If the target carrier is a neighbor cell or carrier measurement not in the EMR list and that carrier is not a higher priority frequency layer measurement, the UE may not perform measurement on that target carrier.
[0062] A second scenario is where the network has indicated that the MR is off, e.g., the UE is not configured perform EMR measurements after T331 has expired based on the EMR configuration. In this second scenario, the UE may determine whether the keep the MR on or turn the MR off based on the following examples. A first condition of the second scenario may be the measurement results of the serving cell meets “Srxlev<=SnonIntraSearchP or Squal<=SnonIntraSearchQ” (e.g., the neighbor cell measurement thresholds are satisfied) . If the first condition of the second scenario is satisfied, the UE may keep the MR on to perform serving cell measurements and neighbor cell or carrier measurements not in EMR list with relaxation mode, but the UE may not perform neighbor cell or carrier measurement in EMR list unless these neighbor cells are configured as legacy measurement carriers.
[0063] A second condition of the second scenario may be that the serving cell measurement results satisfy “Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ, ” e.g., neighbor cell measurement thresholds are not satisfied. If the second condition of the second scenario is satisfied, there may be two alternatives. In a first alternative, the UE may keep the MR OFF, meaning that no measurements are performed by the MR. In a second alternative, the UE may use the MR to (1) perform neighbor cell or carrier measurements not in EMR list if the target carrier is a higher priority frequency layer measurement with or without relaxation mode, but (2) not perform neighbor cell or carrier measurements in the EMR list unless these neighbor cells are configured as legacy measurement carriers. If these cells or carriers are also configured as the legacy measurement carriers, the UE may perform higher priority frequency layer measurement with or without relaxation.
[0064] In some example embodiments, the network may not have indicated the status of the MR. Rather the UE may indicate an exit condition of the MR offloading. For example, the network may indicate that when a condition occurs (e.g., the MR offload threshold described above) , the UE is to exit the offloading scenario. In these example embodiments, the UE may keep the MR off unless the UE meets the MR offloading exit condition. If the measurement results of the serving cell meets the condition “Srxlev<=SnonIntraSearchP or Squal<=SnonIntraSearchQ, ” the UE may use the MR to perform serving cell measurements and neighbor cell or carrier measurements not in the EMR list with relaxation mode, but the UE may not perform neighbor cell or carrier measurements in the EMR list unless these neighbor cells are configured as legacy measurement carriers.
[0065] If the measurement results of the serving cell meets “Srxlev>SnonIntraSearchP and Squal>SnonIntraSearchQ” there may be two options. In a first option, the UE may keep the MR off and no measurements are performed by the MR. In a second option, the UE may use the MR to (1) perform neighbor cell or carrier measurements not in EMR list in the same manner as the higher priority frequency layer measurements with or without relaxation mode, but (2) may not perform neighbor cell or carrier measurements in the EMR list unless these neighbor cells are configured as legacy measurement carriers. If these cells or carriers are also configured as the legacy cells or carriers, the UE may perform higher priority frequency layer measurements with or without relaxation mode.
[0066] In some example embodiments, a new timer may be introduced to indicate whether the UE may keep the MR on or off after the timer T331 expires. The new timer may be started at the same time as the T331 timer, may be started when the T331 timer expires or may be started at any time while the EMR configuration is valid. For example, if the new timer is running, and not expired, the UE may keep the MR on regardless of whether the MR offloading condition is met or not. If the new timer is expired, the UE may perform the same operations as described above for the scenario where the UE may keep the MR off unless the UE meets the MR offloading exit condition.
[0067] In a scenario where a UE supports idleInactiveNR-MeasReport-r16 or idleInactiveEUTRA-MeasReport-r16 (e.g., the UE supports EMR) and the network configures carriers for idle mode CA / DC measurement reporting without a T331 timer, this may be an ambiguous configuration, e.g., a UE implementation may determine whether carriers or neighbor cells in the EMR list are to be measured.
[0068] In some example embodiments, this scenario may be avoided. For example, the network may be prevented from providing this configuration to the UE. In these example embodiments, when EMR is configured for the UE, the network may also configure the T331 timer for the UE, otherwise no LP-WUR based RRM requirements may be applied to the UE.
[0069] In other example embodiments, if the UE is provided with the ambiguous configuration, the UE may determine to perform the EMR measurements and keep the MR on regardless of whether the MR offloading condition is met.
[0070] In further example embodiments, if the UE is provided with the ambiguous configuration, the UE may determine to not perform the EMR measurements and keep the MR off unless the UE meets the MR offloading exit condition.
[0071] In additional example embodiments, if the UE is provided with the ambiguous configuration, the network may provide an explicit indication as to whether the EMR measurements are required. If the network indicates the EMR measurements are required, the UE may keep the MR on regardless of whether the MR offloading condition is met. If the network indicates the EMR measurements are not required, the UE may keep the MR off unless the UE meets the MR offloading exit condition.
