Abstract
Description
Impact From Measurement Gap Cancellation Due To Extended Reality (XR) TrafficBackground
[0001] Wireless communication networks provide integrated communication platforms and telecommunication services to wireless user devices. Example telecommunication services include telephony, data (e.g., voice, audio, and / or video data) , messaging, internet-access, and / or other services. The wireless communication networks have wireless network nodes that exchange wireless signals with the wireless user devices using wireless network protocols, such as protocols described in various telecommunication standards promulgated by the Third Generation Partnership Project (3GPP) . Example wireless communication networks include code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency-division multiple access (FDMA) networks, orthogonal frequency-division multiple access (OFDMA) networks, Long Term Evolution (LTE) , and Fifth Generation New Radio (5G NR) .
[0002] In wireless communications, a base station or other network node may perform various radio resource management (RRM) operations based on the measurements made by a user equipment (UE) . There may be measurement gaps (MGs) or other restrictions to allow the UE to perform the RRM measurements. In some wireless communication systems, capacity may be increased by enabling data transmission / reception during the MGs / restrictions. In these systems, the measurement gaps may be cancelled, allowing the network to schedule data during the cancelled gaps and UEs to respond to network scheduling during the cancelled gaps. However, where there is some other data scheduling restrictions on the cancelled gaps, there is uncertainty as to how the network and UEs should behave. Thus, there is a need to handle the situation where there is a data scheduling restriction during a cancelled measurement gap.Summary
[0003] Some example embodiments are related to an apparatus having processing circuitry configured to process, based on signaling from a network node, configuration information for Radio Resource Management (RRM) measurements, the configuration information including an indication to cancel at least one measurement gap, determine, based at least in part on the configuration information, whether to perform RRM measurements during a cancelled measurement gap when there is a data scheduling restriction and perform RRM measurements during the cancelled measurement gap when it is determined that RRM measurements should be performed during the cancelled measurement gap.
[0004] Other example embodiments are related to an apparatus having processing circuitry configured to generate, for transmission to a user equipment (UE) , configuration information for Radio Resource Control (RRC) measurements comprising a network indication as to whether to perform RRM measurements during a cancelled measurement gap when there is a data scheduling restriction; process, based on signaling from the UE, RRM measurement information; and perform RRM management operations based at least in part on the received RRM measurement information.Brief Description of the Drawings

[0013] 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. However, it will be apparent to those skilled in the art having the benefit of the present disclosure that the various aspects of the various aspects may be practiced in other examples that depart from these specific details. In certain instances, descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the various aspects with unnecessary detail. For the purposes of the present document, the phrase “A or B” means (A) , (B) , or (A and B) ; and the phrase “based on A” means “based at least in part on A, ” for example, it could be “based solely on A” or it could be “based in part on A. ”
[0014] The example embodiments relate to Radio Resource Management (RRM) requirements, to be described in greater detail below. Specifically, the example embodiments describe how to handle network and UE behaviors during measurement gap cancellations when there is one or more data scheduling restrictions due to RRM measurements.
[0015] 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 a network and is configured with the hardware, software, and / or firmware to exchange information and data with the network. Therefore, the UE as described herein is used to represent any appropriate type of electronic component.
[0016] 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 legacy networks or future evolutions of the cellular protocol (e.g., 6G networks) capable of performing wireless operations. This may include terrestrial networks, non-terrestrial networks, geosynchronous networks, non-geosynchronous networks, etc., and is particularly useful in any network where RRM measurements are performed and where measurement gaps are cancelled in order to increase capacity.
[0017] RRM measurements may generally refer to Layer 3 (L3) measurements. However, throughout this description, the term RRM measurements refers to L3 measurements and / or Layer 1 (L1) measurements. Thus, any reference to an RRM measurement may refer to either an L1 measurement or an L3 measurement.
[0018] A UE may be configured to perform RRM measurements. The example embodiments are described with reference to a method of deciding whether to perform RRM measurements during cancelled measurement gaps when there are data scheduling restrictions due to the RRM measurements.
[0019] 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, phablets, 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 a single UE 110 is merely provided for illustrative purposes.
[0020] The UE 110 may be configured to communicate with one or more networks. In the example of the network configuration 100, the network with which the UE 110 may wirelessly communicate is a 5G NR radio access network (RAN) 120. However, the UE 110 may also communicate with other types of networks (e.g., sixth generation (6G) RAN, 5G cloud RAN, a next generation RAN (NG-RAN) , a long-term evolution (LTE) RAN, a legacy cellular network, a wireless local area network (WLAN) , 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 at least a 5G NR chipset to communicate with the 5G NR RAN 120. The UE 110 may also have other chipsets to communicate with other types of RANs, e.g., LTE chipset, ISM chipset, etc.
[0021] The 5G NR RAN 120 may be a portion of a cellular network that may be deployed by a network carrier (e.g., Verizon, AT&T, T-Mobile, etc. ) . The 5G NR RAN 120 may include base stations or access nodes (Node Bs, eNodeBs, HeNBs, eNBS, gNBs, gNodeBs, macrocells, microcells, small cells, femtocells, etc. ) that are configured to send and receive traffic from UEs that are equipped with the appropriate cellular chip set. As used herein, the term “base station, ” “access node, ” “access point, ” or the like may describe equipment that provides the radio baseband functions for data and / or voice connectivity between a network and one or more users. These access nodes may be referred to as BS, gNBs, RAN nodes, eNBs, NodeBs, RSUs, TRxPs or TRPs, and so forth, and may comprise ground stations (e.g., terrestrial access points) or satellite stations providing coverage within a geographic area (e.g., a cell) . In fact, in some embodiments, a UE, such as UE 110 described herein, may function as an access point. In one example, the 5G NR RAN 120 includes the gNB 120A. 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. ) .
[0022] In the network arrangement 100, the 5G NR RAN 120 deploys a gNB 120A. The gNB 120A may be configured with multiple TRPs. Each TRP may represent one or more components configured to transmit and / or receive a signal. In some embodiments, multiple TRPs may be deployed locally at the gNB 120A. In other embodiments, multiple TRPs may be distributed at different locations and connected to the gNB 120A via a backhaul connection. For example, multiple small cells may be deployed at different locations and connected to the gNB 120A. However, these examples are merely provided for illustrative purposes. TRPs are configured to be adaptable to a wide variety of different conditions and deployment scenarios. Thus, any reference to a TRP being a particular network component or multiple TRPs being deployed in a particular arrangement is merely provided for illustrative purposes. The TRPs described herein may represent any type of network component configured to transmit and / or receive a beam.
[0023] 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., the gNB 120A) .
[0024] 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.
[0025] 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.
[0026] The processor 205 may be configured to execute a plurality of engines for the UE 110. For example, the engines may include a RRM measurement engine 235 for performing operations related to RRM measurements. For example, the RRM measurement engine 235 may perform Layer 1 (L1) measurements, such as reference signal receive power (RSRP) measurements at L1, according to configuration information received from a network node. The RRM measurement engine 235 may also perform L3 RRM measurements, such as reference signal receive power (RSRP) measurements. In addition, the RRM measurement engine 235 may may generate and send a measurement report to the network node. The RRM measurement engine 235 may also send an indication to the network (e.g., gNB 120A) that describes the capabilities of the UE with respect to measurements. These operations will be described in greater detail below.
[0027] The above referenced engine being an application (e.g., a program) executed by the processor 205 is only an 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.
[0028] 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. 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. Accordingly, the transceiver 225 may operate on a variety of different frequencies or channels (e.g., set of consecutive frequencies) . For example, the transceiver 225 may operate on the unlicensed spectrum when e.g., NR-U is configured.
[0029] 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.
[0030] 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 type of access node through which the UE 110 may establish a connection and manage network operations. As used herein, the term “base station” may also refer to an “access node, ” “access point, ” or the like and may describe equipment that provides the radio baseband functions for data and / or voice connectivity between a network and one or more users. These base stations and access nodes may be referred to as BS, gNB s, RAN nodes, eNBs, NodeBs, RSUs, TRxPs or TRPs, and so forth, and may comprise ground stations (e.g., terrestrial access points) or satellite stations providing coverage within a geographic area (e.g., a cell) .
[0031] The base station 300 may include a processor 305, a memory arrangement 310, an input / output (I / O) device 315, a transceiver 320, other components 325, and multiple TRPs 330. 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, TxRUs, transceiver chains, antenna elements, antenna panels, etc.
[0032] As indicated above, in some scenarios, the multiple TRPs 330 may be deployed locally at the base station 300. In other scenarios, one or more of the multiple TRPs 330 may be deployed at physical locations remote from the base station 300 and connected to the base station via a backhaul connection. The base station 300 may be configured to control the multiple TRPs 330 and perform operations such as, but not limited to, assigning resources, configuring reference signals, implementing beam management techniques, etc.
[0033] The processor 305 may be configured to execute a plurality of engines of the base station 300. For example, the engines may include a RRM engine 335 that may perform operations related to radio resource management. For example, the RRM engine 335 may send configuration information for measurements to a user equipment (UE) , wherein the configuration information includes information that may be used to determine whether or not the UE is to perform measurements during a cancelled measurement gap when there is a data scheduling restriction due to measurements. For example, the RRM engine 335 may send a network indication to the UE to select between options as to whether scheduling restrictions apply and whether measurements should be performed during time periods that overlap with a cancelled MG. The RRM engine 335 may receive, from the UE, measurements, and may use the measurements to perform various activities, including deciding whether to activate or indicate transmission configuration indication (TCI) states for the UE. These operations will be described in greater detail below.
[0034] The above noted engine 335 being an application (e.g., a program) executed by the processor 305 is only an example. The functionality associated with the engine 335 may also be represented as a separate incorporated component of the base station 300 or may be a modular component coupled to the base station 300, 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. In addition, in some base stations, the functionality described for the processor 305 is split among a plurality of processors (e.g., a baseband processor, an applications processor, etc. ) . The example embodiments may be implemented in any of these or other configurations of a base station.
[0035] The memory 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.
[0036] The transceiver 320 may be a hardware component configured to exchange data with the UE 110 and any other UEs in the network arrangement 100. The transceiver 320 may operate on a variety of different frequencies or channels (e.g., set of consecutive frequencies) . Therefore, the transceiver 320 may include one or more components (e.g., radios) to enable the data exchange with the various networks and UEs. 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.
[0037] To adapt to changes in a radio environment and relative positioning between the UE 110 and the base stations, the UE 110 may be configured to perform a variety of measurements on reference signals transmitted in both a serving cell (SC) and a non-serving cell (NSC) . The base station (e.g., gNB 120A) may transmit measurement configurations to provide the UE 110 with information to perform the reference signal measurements. Upon performing the measurements, the UE 110 may provide a measurement report to the base station (gNB 120A) . The base station may perform various radio resource management (RRM) operations based on the measurement report.
[0038] The measurement configurations may instruct the UE 110 to perform measurements based on reference signals that include, for example, channel-state information -reference signals (CSI-RSs) and synchronization signal and physical broadcast channel blocks (SSBs) . The measurements may be beam-level or cell-level.
[0039] The measurement configurations may be transmitted to the UE 1110 while the UE 110 is in a radio resource control (RRC) -connected mode by dedicated signaling, such as RRC signaling (for example, an RRC reconfiguration message or RRC resume message) .
[0040] In some embodiments, a measurement configuration may include (directly or by reference) a measurement identity, a measurement object, and a reporting configuration. The measurement identity may link a reporting configuration to a measurement object. The measurement identity may include a first pointer toward a reporting configuration and a second pointer toward a measurement object that provides information about the SSB resources that are to be measured. The UE 110 may provide measurement results within an RRC message (for example, an RRC measurement report) that includes the measurement ID as a reference.
[0041] The reporting configuration may provide a periodic, event-triggered, or cell global identity (CGI) configuration. The reporting configuration may include parameters, such as report amount, reporting interval, and, if the configuration is an event-triggered configuration, a measurement reporting event. The report amount and reporting interval may be abstract syntax notation one (ASN. 1) fields in a report configuration information element (IE) . The report amount may describe how many times a measurement report is to be transmitted based on a triggering event. The triggering event may be a period elapsing (for a periodic configuration) or a triggering condition of a measurement reporting event being satisfied (for an event-triggered configuration) . The reporting interval may provide a time between successive transmissions of the measurement report. The reporting configuration may further describe the reference signal type (for example, SSB) that may be used for the periodic or event-triggered configurations.
[0042] The SSBs may be used for reference signal receive power (RSRP) measurements at Layer 1 (L1) or Layer 3 (L3) . The L1 measurements may be used to monitor and respond to radio channel conditions on a shorter time frame as compared with L3 measurements. The L1 measurements may be used to, for example, perform beam management procedures, while the L3 measurements may be used to, for example, perform handover procedures.
[0043] In some embodiments, consistent with Release 17 3GPP TSs definition of further enhanced multiple-input, multiple-output (FeMIMO) in 3GPP TS 38.214 v17.2.0 (2022-06-23) and TS 38.331 v17.1.0 (2022-07-19) , the UE 110 may be configured for L1-reference signal received power (RSRP) measurements on the non-serving cell. The non-serving cell may have a different physical cell identity (PCI) than the PCI of the serving cell. In some embodiments, the non-serving cell may be referred to as a cell with different (or additional) PCI (CDP) . The L1-RSRP measurements for the non-serving cell may provide the basis for inter-cell beam management. The serving base station may use inter-cell beam management to instruct the UE 110 to switch from a beam associated with the serving cell to a beam associated with the non-serving cell for receiving a physical downlink shared channel (PDSCH) or physical downlink control channel (PDCCH) . This may be done with a simple transmission configuration indication (TCI) state switch without having to do a complete handover, which relies on layer 3 (L3) measurements and takes more time. Performing this dynamic beam switch may often be done when the UE 110 is operating in the higher frequency ranges, for example, frequency range 2 (FR2) , from 24.25 GHz to 52.6 GHz, or above.
[0044] Performing L1-RSRP measurements on CDPs requires coordinated management of a number of measurement configurations. For example, SSB occasions from the serving cell may overlap with SSB occasions from the non-serving cell. Furthermore, the SSB occasions (from either the serving cell or non-serving cell) may overlap with occasions from a measurement gap (MG) configuration (used for inter-frequency or inter-radio access technology (RAT) measurements) and occasions from SSB measurement timing configuration (SMTC) (used to define the measurement opportunities for performing the L3 measurements) .
[0045] One of the objectives of R19 XR (eXtended Reality) for NR Phase 3 is to realize system capacity gains by enabling transmission / reception in gaps / restrictions that are caused by RRM measurements, while keeping impact to mobility performance limited. In particular, one objective can be described as follows: Specify enhancements to enable transmission / reception in gaps / restrictions that are caused by RRM measurements (from inter-frequency RRM measurement gaps, or intra-frequency measurements, or other scheduling restrictions, etc. ) [RAN1, RAN2, RAN4] , and in particular, to specify the corresponding measurement gap and scheduling restriction to enable the identified enhancements with RRM performance impact taken into consideration.
[0046] The following working assumption was made in RANi#118: For solutions based on triggering / enabling by network signaling to enable Tx / Rx in gaps / restrictions that are caused by RRM measurements, the following options may be selected: Alt. 1: Dynamic indication to enable Tx / Rx, in particular any gaps / restrictions that are caused by RRM measurements; Alt 1-1: Explicit indication by DCI to skip a particular gap / restriction, where the indication is included as part of scheduling DCI, the bit-field size is one bit, and the bit in the DCI is used to indicate whether to skip the first gap / restriction occasion after a minimum time offset required between the last symbol of the PDCCH carrying the DCI format and the start of corresponding skipped gap / restriction occasion indicated by the DCI.
[0047] Both network and UE behaviors are being discussed in 3GPP with regard to the impact from gap cancellation due to XR traffic. As the simplest case, assuming there is not any data scheduling restriction (s) after a gap cancellation, the network and UE behaviors may be clear, i.e., the network can schedule data on the gap occasions which are cancelled, and the UE may be able to respond to network scheduling during the cancelled gap occasion. However, network and UE behaviors are unclear when there is a data scheduling restriction (s) on the gap occasions which are cancelled. Thus, this issue needs to be addressed.
[0048] According to TS38.133, data scheduling restrictions due to RRM measurement may be caused by the following reasons. First, where a target SSB is to be measured with a different frequency compared to the serving cell PDSCH, e.g. 15KHz for SSB and 30kHz for PDSCH, and the UE does not support mixed frequencies (simultaneousRxDataSSBDiffNumerology) , e.g. TS38.133 section 9.2.5.3.2) . For UEs which do not support simultaneousRxDataSSB-DiffNumerology, the following restrictions apply due to SS-RSRP / RSRQ (Reference Signal Received Quality) / SINR (Signal to Interference Noise Ratio) measurement: If deriveSSB_IndexFromCell is enabled, the UE is not expected to transmit PUCCH / PUSCH / SRS (Sounding Reference Signal) or receive PDCCH / PDSCH / TRS (Tracking Reference Signal) / CSI-RS for Channel Quality Indicator (CQI) on SSB symbols to be measured, and on one (1) data symbol before each consecutive SSB symbols to be measured and one (1) data symbol after each consecutive SSB symbols to be measured within SMTC window duration. If the high layer signaling of smtc2 is configured (in TS 38.331 [2] ) , the SMTC periodicity follows smtc2; otherwise, the SMTC periodicity follows smtc1. If deriveSSB_IndexFromCell is not enabled, the UE is not expected to transmit PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI on all symbols within the SMTC window duration. If the high layer signaling of smtc2 is configured in TS 38.331 [2] , the SMTC periodicity follows smtc2; otherwise, the SMTC periodicity follows smtc1.
[0049] Second, data scheduling restrictions due to RRM measurement may be caused where a target reference signal (RS) is to measure overlaps with the uplink (UL) in the TDD (Time Division Duplex) band. Third, data scheduling restrictions due to RRM measurement may be caused where a target cell is to measure is an intra-band neighbor cell in Frequency Range 2 (FR2) (scheduling restriction applies to the serving cell (s) on the same band) .
[0050] To address data scheduling restrictions due to RRM measurements, particularly where there is a cancelled MG, the following solutions are proposed. Fig. 4 shows an example diagram where a cancelled gap overlaps with a RRM measurement causing a data scheduling restriction, where legacy scheduling restrictions apply on the SSB to measure within a SSB measurement timing configuration (SMTC) window, according to various example embodiments. In one example, the SMTC may have a twenty millisecond (20ms) periodicity and the MG may have a four millisecond (4 ms) periodicity. Further, as seen in Fig. 4, there may be four symbols per SSB. In Fig. 4, data may be received and / or transmitted except during the time periods shaded in black (where there is a MG or other scheduling restriction) . At some point, the network may send a DCI message that indicates to cancel a measurement gap (MG) for additional data transmission / reception. In a first scenario, as seen in Fig. 4, the cancelled measurement gap overlaps with the SMTC that is to be measured with a scheduling restriction. To address this scenario, there are several options. Looking at Fig. 4, in this example, only the first SSB would cause a scheduling restriction. In a first option, legacy scheduling restrictions (if any) apply on the SSB to measure within the SMTC. In this first option, with respect to network behavior, the network is not expected to schedule the UE on those symbols with scheduling restrictions. With respect to UE behavior, the UE may still perform RRM measurement on those SSB (s) within the SMTC, which is overlapping with the MG that is cancelled due to XR traffic.
[0051] Fig. 5 shows an example diagram where a cancelled gap overlaps with a RRM measurement causing a data scheduling restriction and legacy scheduling restrictions do not apply on the SSB to measure within the SMTC according to various example embodiments. In one example, the SMTC may have a twenty millisecond (20ms) periodicity and the MG may have a four millisecond (4 ms) periodicity. Further, as seen in Fig. 5, there may be four symbols per SSB. In Fig. 5, data may be received and / or transmitted except during the time periods shaded in black (where there is a MG or other scheduling restriction) . At some point, the network may send a DCI message that indicates to cancel a measurement gap (MG) for additional data transmission / reception. In this example, as seen in Fig. 5, all SSBs would cause a scheduling restriction. In a second option, as seen in Fig. 5, where the cancelled gap overlaps with a SMTC that is to be measured with a scheduling restriction, legacy scheduling restrictions do not apply on the SSB to measure within SMTC. In the second option, the network may schedule the UE on those symbols with scheduling restrictions. With respect to the UE, the UE is not expected to perform RRM measurement on those SSB (s) within SMTC, which is overlapping with gap that is cancelled due to XR traffic. Effectively, the DCI not only cancels the MG but also cancels other scheduling restrictions that are overlapped with the MG.
[0052] In one embodiment, the decision to not perform RRM measurements on those SSB (s) within the SMTC that overlaps with the measurement gap that is cancelled due to XR traffic may depend on the number of symbols within the SMTC window, the mobility status of the UE (s) , and the amount of XR traffic (data) that is to be transmitted to the UE.
[0053] In a third option to address a scenario where a cancelled gap overlaps with a SMTC that is to be measured with a scheduling restriction, a network indication X may be introduced that selects between the above first and second options (i.e., whether or not the legacy scheduling restrictions apply on the SSB to measure within SMTC) . In one example, if X=i, option 1 is selected and the legacy scheduling restrictions apply on the SSB to measure within the SMTC, and if X=2, then option 2 is selected and the legacy scheduling restrictions do not apply on the SSB to measure within the SMTC. The new network indication may be indicated via Radio Resource Control (RRC) , Media Access Control-Control Element (MAC-CE) , or Downlink Control Information (DCI) messaging.
[0054] When to set X=i or X=2 is up to network implementation. For instance, in one example, if there is only a small portion of SMTC that is to be measured with scheduling restriction, the network may set X=i to minimize a negative impact on mobility. On the other hand, if most or a majority of the symbols within SMTC are to be measured with a scheduling restriction, the network may set X=2; otherwise, throughput may not be able to be increased to a needed level even though the network cancels the MG.
[0055] In addition, in order to carry out the proposed schemes disclosed herein, new UE capabilities Y may be introduced to indicate support of the first scenario discussed above. In one embodiment, different capabilities can be considered for different options, e.g. a first UE capability Y1 may correspond to option 1, a second UE capability Y2 may correspond to option 2, and a third UE capability Y3 may correspond to option 3. The new UE capability Y can be specified per UE, per Frequency Range (FR) , per Band Combination (BC) when doing Carrier Aggregation (CA) , and / or per Feature Set (FS) .
[0056] A second scenario that needs to be addressed is where a cancelled gap overlaps with L1 RS that is to be measured with scheduling restriction. For purposes of this scenario 2, “L1 RS” means SSB or CSI-RS that is configured for L1 operations including: Radio link monitoring (RLM) ; Beam failure detection (BFD) ; Candidate beam discovery (CBD) ; L1-RSRP measurement on serving cell; L1-SINR measurement on serving cell; L1-RSRP measurement on cell with different PCI; L1-SINR measurement on cell with different PCI; and L1-RSRP measurement on neighbor cell. The previously disclosed solutions under the first scenario regarding a cancelled MG overlapping with a SMTC that is to be measured with a scheduling restriction (see Figs. 4 and 5 and accompanying text) also apply here, with the following exceptions. Different network indications can be considered for different L1 operations, e.g. XRLM for RLM, XBFD for BFD, and etc. That is, the network indication may vary for different L1 operations. In addition, different UE capabilities can be considered for different L1 operations, e.g. YRLM-opt1 for RLM with option 1, YBFD-opt2 for BFD with option 2, and etc.
[0057] A third scenario that needs to be addressed is where a cancelled measurement gap overlaps with another measurement gap. As introduced in R17, a UE can be configured with more than one concurrent measurement gap pattern. For purposes of this scenario, different gap patterns means there is at least one of the following parameters that is different between the two gap patterns: time offset, measurement gap length (MGL) , measurement gap repetition period (MGRP) , and / or measurement gap timing advance (MGTA) . Ideally, the measurement gaps do not overlap, but occasionally they will in fact overlap due to network conditions and / or the target RS, particularly with respect to positioning RS.
[0058] Fig. 6 shows an example diagram where a cancelled measurement gap overlaps with another measurement gap according to various example embodiments. That is, MG1 may overlap with MG2 on some occasions. In case of a collision, the gap with lower priority would be dropped according to current 3GPP design (TS38.133 9.1.8.3) .
[0059] Collisions between occasions of two concurrent measurement gaps may occur if the two measurement gaps are: two per-UE measurement gaps, two per-FR measurement gaps in the same FR, or one per-UE measurement gap and one per-FR measurement gap. When a UE is configured with concurrent measurement gaps, two measurement gap occasions are considered colliding if at least one of the following conditions is met: the two occasions are fully or partially overlapping in time domain, or the distance between the two occasions is equal to or smaller than four milliseconds (4ms) . The distance between two measurement gap occasions is defined as the time difference between the ending point of the first occasion and the starting point of the second occasion, where the first measurement gap occasion occurs earlier in time than the second measurement gap occasion. In case of a collision between two measurement gap occasions, the UE shall perform measurements in the occasion of the measurement gap with higher priority, and the occasion of the measurement gap with lower priority shall be dropped. The UE shall be able to transmit PUCCH / PUSCH / SRS or receive PDCCH / PDSCH / TRS / CSI-RS for CQI in the corresponding NR serving cells in the slots that are not interrupted. The requirements of concurrent measurement gaps shall not apply when a gap without assigned priority is configured simultaneously with any other gap (s) that affect serving carriers in the same FR and the measurement gaps are colliding with each other. The priority for a measurement gap is configured by networks via gapPriority in GapConfig. The requirements with concurrent measurement gaps apply provided that two measurement gaps colliding with each other are configured with different priorities.
[0060] As seen in Fig. 6, MG2 has the higher priority in this example, and so MG1 is dropped where MG1 overlaps with MG2. The non-overlapping occasions of MG1 are not cancelled.
[0061] To address the third scenario where a cancelled MG overlaps with another MG, there are several options. Fig. 7 shows an example diagram of a first example scheme to handle a scenario where a cancelled measurement gap overlaps with another measurement gap according to various example embodiments. In Fig. 7, MG1 may overlap with MG2 on some occasions. At some point, a DCI message is sent to cancel MG2. In a first option, as seen in Fig. 7, the network is not expected to schedule a UE within the MG occasion (MG1) which overlaps with another MG occasion that is canceled by the network (MG2) due to XR traffic. Thus, it is effectively as if there is no MG2 and only MG1 remains. With respect to UE behavior, the UE may still use the MG with lower priority (MG1) to perform measurements. The UE does not need to perform data Rx / Tx during the MG with lower priority.
[0062] Fig. 8 shows an example diagram of a second example scheme to handle a scenario where a cancelled measurement gap overlaps with another measurement gap according to various example embodiments. In Fig 8, MG1 may overlap with MG2 on some occasions. At some point, a DCI message is sent to cancel MG2. In a second option, as seen in Fig. 8, the network may schedule a UE on those symbols with scheduling restrictions. With respect to UE behavior, the UE is not expected to use the MG with the lower priority (MG1) . Effectively, in the second option, the network uses the same DCI to cancel the MG occasion and all other overlapped MG occasion with lower priority. Thus, in Fig. 8, both MG1 and MG2 are cancelled after the DCI message.
[0063] In a third option to address the scenario where a cancelled MG overlaps with another MG, a new network indication X3 may be introduced to select between option 1 and 2, e.g., X3=l means option 1 while X3=2 means option 2. The new network indication can be indicated via RRC, MAC-CE, and / or DCI. When to set X3 = 1 or X3 = 2 is up to network implementation. For instance, if the overlapped MG is short (e.g., MGL = 3ms) or there is a larger MGRP (e.g., MGRP = 160ms) , the network may set X=i to minimize any negative impact on RRM based on the lower priority MG. If the overlapped MG has a long MGL, the network may set X = 2; otherwise, the throughput may not be able to be increased to a needed level even though the network cancels the MG with higher priority.
