Description

Communication control methods and devices, terminals and storage media Technical Field

[0001] This disclosure relates to the field of communication technology, and more specifically, to communication control methods, communication control devices, terminals, and storage media. Background Technology

[0002] The terminal can report Layer 1 (L1) measurements to the network device. L1 measurement reporting can include event-triggered L1 measurement reporting, such as when a specific measurement event is met, the terminal performs L1 measurement reporting.

[0003] The problem with the above process is that when the terminal determines that a specific measurement reporting event is met, it determines that L1 measurement reporting needs to be performed. However, when the terminal obtains the resources for L1 measurement reporting, the specific measurement reporting event is no longer met. In this case, if L1 measurement reporting is continued, it will cause problems.

[0066] As shown in Figure 1, the communication system 100 includes a terminal 101 and a network device 102, wherein the network device includes at least one of the following: an access network device and a core network device.

[0067] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal device in industrial control, wireless terminal device in self-driving, wireless terminal device in remote medical surgery, wireless terminal device in smart grid, wireless terminal device in transportation safety, wireless terminal device in smart city, and wireless terminal device in smart home.

Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), or a Next Generation Core (NGC).

[0070] In some embodiments, the technical solutions of this disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within access network devices involved in the embodiments of this disclosure can be transformed into internal interfaces of Open RAN. The processes and information interactions between these internal interfaces can be implemented by software or programs.

[0071] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.

[0072] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0073] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0074] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0075] In some embodiments, dynamic cell (or cell group) change technology is proposed to improve the efficiency of terminal handover to a cell (or cell group).

[0076] For example, in a 5G system, network equipment can provide a terminal with one or more candidate configurations (also known as candidate cell (or cell group) configurations), where one candidate configuration can correspond to one or more "cells (or cell groups)". The network equipment can subsequently control the terminal to change among the multiple candidate configurations via L1 signaling (e.g., DCI (Downlink Control Information)) or L2 signaling (e.g., MAC CE (Media Access Control Element)). For example, it can change the working cell (or cell group) from cell (or cell group) #1 to cell (or cell group) #2. Since the terminal has already obtained the candidate configuration corresponding to the cell, this facilitates rapid cell switching for communication.

[0077] The aforementioned L1 and L2 signaling can be referred to as "cell change control signaling," and the process of changing the cell can also be called an LTM (L1 / L2-triggered Mobility) process. This cell change process can be assisted by configuring L1 measurement reporting (e.g., reporting CSI (Channel State Information) reports). For example, network devices can select from multiple candidate configurations based on L1 measurement reporting.

[0078] In some embodiments, the configuration for L1 measurement reporting may include at least one of the following:

[0079] L1 measurement resource configuration, L1 measurement reporting configuration, and L1 measurement reporting content.

[0080] In some embodiments, regarding L1 measurement resource configuration, for example, for a candidate configuration (e.g., it can be denoted as LTM-Candidate), the network device can configure the L1 measurement resources (e.g., ltm-nzp-CSI-RS-ResourceToAddModList) of the candidate cells corresponding to the candidate configuration.

[0081] In some embodiments, regarding L1 measurement reporting configuration, the network device can configure the terminal's measurement reporting configuration in the serving cell. For example, the measurement reporting configuration includes at least one of the following:

[0082] L1 measurement reporting corresponds to the L1 measurement resource (e.g., ltm-ResourcesForChannelMeasurement).

[0083] L1 measurement reporting type.

[0084] In some embodiments, the L1 measurement reporting type includes any of the following:

[0085] Periodic reporting (e.g., periodic);

[0086] PUCCH (Physical Uplink Control Channel) semi-persistent reporting (e.g., semiPersistentOnPUCCH);

[0087] PUSCH (Physical Uplink Shared Channel) semi-persistent reporting (e.g., semiPersistentOnPUSCH);

[0088] Non-periodic reporting (e.g., aperiodic);

[0089] Event-triggered reporting (e.g., event).

[0090] In some embodiments, the L1 measurement reporting content may include at least one of the following:

[0091] The number of cells corresponding to the reported results in a single L1 measurement report (e.g., nrOfReportedCells);

[0092] The number of reference signals for each cell corresponding to the reported results in a single L1 measurement report (e.g., nrOfReportedRS-PerCell);

[0093] Whether to report the matching information of the L1 measurement results of the currently served SpCell (e.g., spCellInclusion).

[0094] In some embodiments, in order to support the LTM process, the network device can configure the terminal to have an L1 measurement reporting process based on "event-triggered reporting". Then, after a specific measurement reporting event is met, the terminal reports (or sends) its L1 measurement results to the network device. For example, it can report to the network device through a MAC CE for L1 measurement reporting.

[0095] In some embodiments, when a terminal sends a MAC CE, it needs to send it on the uplink time-frequency resources specified by the uplink authorization allocated by the network. In order for the terminal to quickly notify the network device to obtain uplink authorization, the network device can allocate SR (Scheduling Request) resources for the MAC CE used for L1 measurement reporting. Then, when the terminal triggers the reporting of the MAC CE used for L1 measurement reporting, the terminal can send an SR to quickly notify the network device that it needs to provide the corresponding uplink authorization for the terminal.

[0096] In some embodiments, regarding event-triggered measurement reporting, the network device can configure a specific measurement reporting event for the terminal. When the terminal satisfies the specific measurement reporting event, it will report the L1 measurement result to the network device. For example, the measurement reporting event may include at least one of the following:

[0097] Event A1: The serving cell (or cell group) signal quality is better than the threshold.

[0098] Event A2: The signal quality of the serving cell (or cell group) is below the threshold.

[0099] Event A3: The signal quality of the neighboring cell (or cell group) is better than the signal quality of PCell / PSCell by a certain value.

[0100] Event A4: The signal quality of the neighboring cell (or cell group) is better than the threshold.

[0101] Event A5: PCell / PSCell signal quality is below the threshold, and neighbor cell (or cell group) signal quality is better than the threshold (PCell / PSCell becomes worse than threshold1 and neighbor becomes better than threshold2).

[0102] Event A6: The signal quality of the neighboring cell (or cell group) is better than the SCell signal quality by a certain value.

[0103] In some embodiments, when evaluating whether a measurement reporting event is met, the terminal can determine whether to trigger L1 measurement reporting based on the Entering Condition and Leaving Condition.

[0104] For example, taking Event A3 above as an example. When the duration for which the terminal's cell measurement result meets the Entering Condition of Event A3 (e.g., the signal quality of the neighboring cell (or cell group) is better than the PCell / PSCell signal quality by a certain value) is greater than or equal to the threshold value configured by the network device, the terminal triggers L1 measurement reporting. When the duration for which the terminal's cell measurement result meets the Leaving Condition of Event A3 (e.g., the signal quality of the neighboring cell (or cell group) is lower than the PCell / PSCell signal quality by a certain value) reaches the threshold value configured by the network, the terminal cancels L1 measurement reporting (e.g., removes the L1 measurement result to be reported).

[0105] In some embodiments, in an event-triggered measurement reporting scenario, after the terminal triggers a MAC CE report for L1 measurement reporting, it needs a certain period of time to obtain uplink authorization from the network device before it can send the MAC CE for L1 measurement reporting to the network device based on the resources specified in the uplink authorization. During this period, if the terminal has configured SR resources, it can also trigger the corresponding SR transmission.

[0106] However, because the terminal's measurement results (such as the measurement results for cells (or cell groups) and neighboring cells (or cell groups) in the aforementioned events) change over time, in some cases, when the terminal determines that a measurement reporting event is met, it decides that L1 measurement reporting needs to be performed. However, by the time the terminal obtains uplink authorization and determines the resources for sending MAC CE for L1 measurement reporting, the specific measurement reporting event is no longer met. In this situation, continuing to perform L1 measurement reporting will lead to signaling loss due to redundant reporting.

[0107] Figure 2 is a flowchart illustrating a communication control method according to an embodiment of the present disclosure.

[0108] In some embodiments, the communication control method may be executed by the terminal.

[0109] As shown in Figure 2, the communication control method may include the following steps:

[0110] In some embodiments, the terminal triggers L1 measurement reporting.

[0111] In some embodiments, if a first condition is met, the terminal performs at least one of the following operations: cancels L1 measurement reporting; cancels the scheduling request (SR) corresponding to L1 measurement reporting.

[0112] In step S201, the terminal cancels the L1 measurement reporting if the first condition is met.

[0113] In some embodiments, the first condition includes at least one of the following:

[0114] The measurement reporting conditions for triggering L1 measurement reporting are not met;

[0115] The L1 measurement reporting triggered by the measurement reporting conditions has been executed at least once.

[0116] In some embodiments, the first condition includes the measurement reporting condition that triggers L1 measurement reporting not being met.

[0117] For example, when the measurement reporting conditions for triggering L1 measurement reporting are met, the terminal can trigger L1 measurement reporting, and then determine the transmission resources (which may include time domain resources and frequency domain resources) for L1 measurement reporting based on the uplink grant sent by the network device. For example, if L1 measurement reporting is sent via MAC CE, the terminal can determine the transmission resources of the MAC CE for L1 measurement reporting based on the uplink grant sent by the network device.

[0118] If, after the terminal triggers L1 measurement reporting, it is determined that the measurement reporting conditions for triggering L1 measurement reporting are not met, then L1 measurement reporting can be cancelled.

[0119] For example, the measurement reporting conditions that do not trigger L1 measurement reporting may include at least one of the following:

[0120] The departure conditions for the measurement reporting event must be met at least once;

[0121] The leave condition for the measurement reporting event is met at least once, and the network device is not configured to require the terminal to report the L1 measurement result when the leave condition for the measurement reporting event is met (e.g., the network device is not configured to have the terminal reportOnLeave).

[0122] The entry conditions for a measurement reporting event were not met at least once.

[0123] Taking Event A1 above as an example, which corresponds to the measurement reporting condition that triggers L1 measurement reporting:

[0124] For example, the measurement reporting conditions that trigger L1 measurement reporting are not met include meeting the departure conditions of the measurement reporting event. The terminal obtains the measurement results (e.g., the measurement results of the signal of the cell (or cell lease)) and determines whether the measurement results meet Event A1 (e.g., judging from the measurement results that the signal quality of the serving cell (or cell group) is below a threshold).

[0125] If the measurement result meets Event A1, determine an entry condition that satisfies Event A1; if the measurement result does not meet Event A1, determine a exit condition that satisfies Event A1.

[0126] For example, it can be determined whether all measurement results meet the entry conditions of Event A1 within the duration threshold. If all of them meet the entry conditions of Event A1, it can be determined that the measurement reporting condition corresponding to Event A1 meets the measurement reporting condition for triggering L1 measurement reporting, and L1 measurement reporting is triggered. If not all of them meet the entry conditions of Event A1, it can be determined that the measurement reporting condition corresponding to Event A1 does not meet the measurement reporting condition for triggering L1 measurement reporting, and L1 measurement reporting triggered by the measurement reporting condition corresponding to Event A1 is canceled.

[0127] For example, it can be determined whether all measurement results meet the exit condition of Event A1 within the duration threshold. If all of them meet the exit condition of Event A1, it can be determined that the measurement reporting condition corresponding to Event A1 does not meet the measurement reporting condition that triggers L1 measurement reporting, and the L1 measurement reporting triggered by the measurement reporting condition corresponding to Event A1 can be cancelled.

[0128] For example, if it is determined that the measurement departure condition for triggering L1 measurement reporting is met, it can be determined whether the network device is configured to report L1 measurement results when the departure condition of the measurement reporting event is met. If the network device is not configured to report L1 measurement results when the departure condition of the measurement reporting event is met, it can be determined that the measurement reporting condition corresponding to triggering L1 measurement reporting is not met, and the L1 measurement reporting triggered by the measurement reporting condition corresponding to Event A1 can be cancelled.

[0129] In some embodiments, the first condition includes that L1 measurement reporting triggered by the measurement reporting condition has been performed at least once.

[0130] For example, after triggering L1 measurement reporting, the terminal can continue to perform L1 measurement reporting. For instance, if the measurement reporting condition corresponding to Event A1 triggers L1 measurement reporting, the terminal executes the L1 measurement reporting triggered by the measurement reporting condition corresponding to Event A1. Subsequently, if the measurement reporting condition corresponding to Event A3 triggers L1 measurement reporting, the terminal executes the L1 measurement reporting triggered by the measurement reporting condition 3 corresponding to Event A, and also needs to execute the L1 measurement reporting triggered by the measurement reporting condition corresponding to Event A1.

[0131] In this situation, when the terminal is about to execute the L1 measurement report triggered by the measurement reporting condition corresponding to Event A1, it can determine that the L1 measurement report triggered by the measurement reporting condition corresponding to Event A1 has been executed at least once. Therefore, it can cancel the L1 measurement report triggered by the measurement reporting condition corresponding to Event A1, thereby avoiding the waste of communication resources caused by repeatedly reporting the same content.

[0132] According to embodiments of this disclosure, after triggering L1 measurement reporting, the terminal can determine (e.g., periodically or non-periodically) whether a first condition is met. If the first condition is met, the L1 measurement reporting can be canceled, thereby avoiding signaling loss caused by redundant reporting.

[0133] It should be noted that if the terminal determines that the first condition is not met, it may continue to perform L1 measurement reporting, or it may further determine whether to perform L1 measurement reporting based on other conditions. This disclosure does not limit this.

[0134] For example, when the terminal determines that L1 measurement reporting needs to be performed, the communication control method may also include:

[0135] In step S202, the MAC CE used for L1 measurement reporting is sent to the network device.

[0136] In some embodiments, canceling L1 measurement reporting by the terminal may include deleting the results obtained from the L1 measurement reporting. This helps to save terminal storage space.

[0137] In some embodiments, the communication control method further includes: receiving L1 measurement reporting configuration sent by a network device.

[0138] Network devices can send L1 measurement reporting configurations to terminals. The L1 measurement reporting configurations can include the L1 measurement resources corresponding to the L1 measurement reporting, the L1 measurement reporting type, and measurement reporting event configurations.

[0139] For example, the measurement reporting event configuration can be configured to configure the events corresponding to the measurement reporting conditions that trigger L1 measurement reporting. For example, if the measurement reporting event configuration includes Event A3 (e.g., L1 Event-A3), then the terminal can perform L1 measurement reporting only when the measurement reporting conditions corresponding to Event A3 are met, without having to determine whether the measurement reporting conditions corresponding to other events are met.

[0140] In some embodiments, the communication control method further includes: receiving a scheduling request (SR) resource configuration corresponding to an L1 measurement report sent by a network device.

[0141] Network devices can send SR resource configurations corresponding to L1 measurement reporting to terminals. Based on the SR resource configurations corresponding to L1 measurement reporting, terminals can send SRs to network devices to request uplink authorizations from the network devices. Subsequently, terminals can send MAC CEs to network devices based on the resources indicated by the uplink authorizations. The MAC CEs contain the content of the L1 measurement reporting (e.g., L1 measurement results).

[0142] In some embodiments, SR resource configuration includes at least one of the following:

[0143] The location of SR resources, such as the time domain location of SR resources and the frequency domain location of SR resources;

[0144] The type of uplink information (e.g., MAC CE) to which SR resources are applicable, where the uplink information is used to carry L1 measurement reporting;

[0145] Matching information for SR resources.

[0146] For example, the matching information for SR resources includes at least one of the following:

[0147] L1 measures the identifier of the reported event, such as Event number-1;

[0148] L1 measures the type identifier of the reported event, such as Event-A3;

[0149] The identifier of the L1 measurement reporting configuration, for example, if the content of the L1 measurement reporting is CSI, the identifier of the L1 measurement reporting configuration can be the identifier of the CSI report configuration (e.g., CSI Report Config ID);

[0150] The identifier for L1 measurement resource configuration, for example, if the measurement object reported by L1 measurement is CSI-RS (Channel State Information Reference Signal), the identifier for L1 measurement resource configuration can be the identifier of CSI-RS resource (e.g., CSI-RS Resource ID).

[0151] In some embodiments, the communication control method further includes: determining that the L1 measurement report can use the SR resource if the first measurement reporting event corresponding to the L1 measurement report matches the matching information.

[0152] After triggering L1 measurement reporting, the terminal can determine whether the triggered L1 measurement reporting meets the matching information corresponding to the SR resource. Only if the matching information corresponding to the SR resource is met can the terminal use the SR resource corresponding to the L1 measurement reporting.

[0153] For example, the matching information for SR resources configured by the network device for the terminal includes the type identifier of the L1 measurement reporting event, such as L1 Event-3. When the terminal triggers L1 measurement reporting, if the measurement reporting event type corresponding to the measurement reporting condition that triggers L1 measurement reporting is L1 Event-3, it can be determined that the matching information corresponding to the SR resource is satisfied. In this case, the MAC CE used for L1 measurement reporting can trigger the use of the SR resource corresponding to the L1 measurement reporting to send SR. If the measurement reporting event type corresponding to the measurement reporting condition that triggers L1 measurement reporting is not L1 Event-3, it can be determined that the matching information corresponding to the SR resource is not satisfied. In this case, the MAC CE used for L1 measurement reporting cannot trigger the use of the SR resource corresponding to the L1 measurement reporting to send SR.

[0154] For example, the matching information corresponding to the SR resources configured for the terminal by the network device includes the identifier of the L1 measurement reporting configuration, such as CSI Report Config-1. When the terminal triggers L1 measurement reporting, if the identifier of the L1 measurement reporting configuration is CSI Report Config-1, it can be determined that the matching information corresponding to the SR resource is satisfied. In this case, the MAC CE used for L1 measurement reporting can trigger the use of the SR resource corresponding to the L1 measurement reporting to send the SR. If the identifier of the L1 measurement reporting configuration is not CSI Report Config-2, it can be determined that the matching information corresponding to the SR resource is not satisfied. In this case, the MAC CE used for L1 measurement reporting cannot trigger the use of the SR resource corresponding to the L1 measurement reporting to send the SR.

[0155] In some embodiments, the terminal can evaluate the measurement reporting events configured by the network device according to the L1 measurement reporting configuration provided by the network device. For example, it can perform L1 measurement according to the L1 measurement reporting configuration and determine whether the measurement result meets the measurement reporting conditions. If it is determined that the measurement reporting conditions are met, the terminal can trigger the execution of L1 measurement reporting, for example, by sending a MAC CE for L1 measurement reporting to the network device.

[0156] For example, measurement reporting conditions may include at least one of the following:

[0157] The entry conditions for a measurement reporting event must be met at least once;

[0158] The departure condition for the measurement reporting event must be met at least once, and the network device configuration terminal must report the L1 measurement result when the departure condition for the measurement reporting event is met (e.g., network device configuration terminal reportOnLeave).

[0159] In some embodiments, if the first condition is not met, the communication control method further includes: if there are available uplink resources for L1 measurement reporting, performing L1 measurement reporting without triggering SR reporting corresponding to L1 measurement reporting.

[0160] If, even if the first condition is not met, there is available uplink resource (e.g., Uplink Grant) for L1 measurement reporting (e.g., sending a MAC CE for L1 measurement reporting), then the terminal can perform L1 measurement reporting (e.g., sending a MAC CE for L1 measurement reporting via the available uplink resource). Furthermore, the terminal does not need to trigger the corresponding SR report for L1 measurement reporting, i.e., it does not need to send an SR to request uplink grant.

[0161] In some embodiments, if the first condition is not met, the communication control method further includes: triggering SR reporting corresponding to L1 measurement reporting when there are no available uplink resources for L1 measurement reporting, the network device is configured with SR resources corresponding to L1 measurement reporting, and the first measurement reporting event that triggers L1 measurement reporting matches the matching information of the SR resources.

[0162] If the terminal does not meet the first condition, and there is no available uplink resource (e.g., Uplink Grant) for L1 measurement reporting (e.g., for sending MAC CE for L1 measurement reporting), but the network device is configured with SR resource corresponding to L1 measurement reporting, the terminal can determine whether the first measurement reporting event corresponding to the first measurement reporting condition that triggers L1 measurement reporting matches the matching information of the SR resource. If they match, the terminal can trigger the SR reporting corresponding to L1 measurement reporting; otherwise, the terminal will not trigger the SR reporting corresponding to L1 measurement reporting.

[0163] For example, the matching information for L1 measurement reporting corresponding to the SR resources configured for the terminal by the network device includes the identifier of the L1 measurement reporting configuration, which is CSI Report Config-1. When the terminal triggers L1 measurement reporting, if the identifier of the L1 measurement reporting configuration is CSI Report Config-1, it can be determined that the matching information corresponding to the SR resource is satisfied. In this case, the MAC CE used for L1 measurement reporting can trigger the use of the SR resource corresponding to the L1 measurement reporting to send the SR. If the identifier of the L1 measurement reporting configuration is not CSI Report Config-2, it can be determined that the matching information corresponding to the SR resource is not satisfied. In this case, the MAC CE used for L1 measurement reporting cannot trigger the use of the SR resource corresponding to the L1 measurement reporting to send the SR.

[0164] In some embodiments, if the first condition is not met, the communication control method further includes: triggering the SR corresponding to the general SR resource when there is no available uplink resource for L1 measurement reporting, the network device has not configured the SR resource corresponding to L1 measurement reporting, and the network device has configured the general SR resource.

[0165] If the terminal does not meet the first condition, and there is no available uplink resource (e.g., Uplink Grant) for L1 measurement reporting (e.g., for sending MAC CE for L1 measurement reporting), and the network device has not configured the corresponding SR resource for L1 measurement reporting, but the network device has configured a general SR resource (e.g., the network device provides the terminal with a schedulingRequestConfig, where the uplink resource requested by the general SR can be used for L1 measurement reporting or other uplink communication), the terminal can trigger the SR corresponding to the general SR resource, for example, by sending an SR on the general SR resource to request uplink resources, and for example, by sending MAC CE for L1 measurement reporting through the requested uplink resource.

[0166] In some embodiments, if the first condition is not met, the communication control method further includes: triggering a random access procedure if there are no available uplink resources for L1 measurement reporting and the network device is not configured with SR resources.

[0167] If the terminal does not meet the first condition, and there is no available uplink resource (e.g., Uplink Grant) for L1 measurement reporting (e.g., for sending MAC CE for L1 measurement reporting), and the network device has not configured SR resources (e.g., SR resources corresponding to L1 measurement reporting, general SR resources) for the terminal, then the terminal can initiate a random access procedure, and then obtain uplink resources to send MAC CE for L1 measurement reporting after completing the random access procedure.

[0168] In some embodiments, if a first condition is determined to be met, the SR reporting corresponding to the L1 measurement reporting is cancelled.

[0169] After triggering L1 measurement reporting, the terminal can trigger the corresponding SR for L1 measurement reporting. However, if the first condition is met, the terminal can cancel the corresponding SR reporting for L1 measurement reporting.

[0170] In some embodiments, the first condition includes the measurement reporting condition that triggers L1 measurement reporting not being met.

[0171] For example, when the terminal determines that the measurement reporting conditions for triggering L1 measurement reporting are met, it can trigger L1 measurement reporting and then determine the transmission resources (which may include time domain resources and frequency domain resources) for L1 measurement reporting based on the uplink grant sent by the network device. For example, if L1 measurement reporting is sent via MAC CE, the terminal can determine the transmission resources of the MAC CE for L1 measurement reporting based on the uplink grant sent by the network device.

[0172] Specifically, after the terminal triggers the SR report corresponding to the L1 measurement report, if it is determined that the measurement reporting conditions for triggering the L1 measurement report are not met, then the SR report corresponding to the L1 measurement report can be cancelled. Examples of measurement reporting conditions can be found in the previous embodiments, and will not be repeated here.

[0173] In some embodiments, the first condition includes that L1 measurement reporting triggered by the measurement reporting condition has been performed at least once.

[0174] For example, after triggering L1 measurement reporting, the terminal can continue to perform L1 measurement reporting. For instance, if the measurement reporting condition corresponding to Event A1 triggers L1 measurement reporting, the terminal executes the L1 measurement reporting triggered by the measurement reporting condition corresponding to Event A1. Subsequently, if Event A3 triggers L1 measurement reporting, the terminal executes the L1 measurement reporting triggered by the measurement reporting condition corresponding to Event A3, and also needs to execute the L1 measurement reporting triggered by the measurement reporting condition corresponding to Event A1.

[0175] In this situation, when the terminal is about to execute the L1 measurement report triggered by the measurement reporting condition corresponding to Event A1, it can determine that the L1 measurement report triggered by the measurement reporting condition corresponding to Event A1 has been executed at least once. Therefore, it can cancel the SR report corresponding to the L1 measurement report triggered by the measurement reporting condition corresponding to Event A1, thereby avoiding the waste of communication resources caused by repeatedly reporting the same content after requesting resources through SR.

[0176] In some embodiments, the communication control method further includes: in the event that the SR corresponding to the L1 measurement report conflicts with the first SR, determining the SR to be sent according to the priority relationship.

[0177] For example, after triggering L1 measurement reporting, the terminal can trigger the corresponding SR for L1 measurement reporting. The terminal can also trigger the first SR. For example, the uplink resources requested by the first SR are used for uplink communication other than L1 measurement reporting, such as performing beam failure recovery (BFR).

[0178] In this situation, the SR corresponding to the L1 measurement report may conflict with the first SR. For example, if the SR corresponding to the L1 measurement report and the first SR are stored in overlapping time domain resources and / or frequency domain resources, the terminal can select the SR with the higher priority to send based on the priority relationship between the SR corresponding to the L1 measurement report and the first SR. For example, the resources of the relatively higher SR can be determined to be available (e.g., valid).

[0179] For example, the first SR may include at least one of the following: a general SR, or a SR corresponding to beam failure recovery.

[0180] The priority of the SR corresponding to the L1 measurement report and the first SR can include, for example, at least one of the following:

[0181] The priority of the SR corresponding to L1 measurement reporting is higher than that of the general SR (SR other than the SR corresponding to L1 measurement reporting and the SR corresponding to beam failure recovery);

[0182] The priority of the SR corresponding to L1 measurement reporting is higher than that of the SR corresponding to beam failure recovery;

[0183] The priority of the SR corresponding to beam failure recovery is higher than that of the SR corresponding to L1 measurement reporting.

[0184] For example, the priority of the SR corresponding to L1 measurement reporting is higher than that of the general SR. In this case, when the SR corresponding to L1 measurement reporting conflicts with the general SR, the terminal can determine to send the SR corresponding to L1 measurement reporting on the conflicting resource.

[0185] In some embodiments, the communication control method further includes: when the number of SRs corresponding to the L1 measurement reporting is at least two, determining the SR to be sent from the at least two SRs according to priority, or determining any one of the at least two SRs as the SR to be sent.

[0186] For example, after triggering an L1 measurement report, the terminal can trigger the corresponding SR (Search Service Request) for the L1 measurement report. The terminal can trigger multiple L1 measurement reports, each corresponding to a separate SR. In this case, multiple SRs corresponding to L1 measurement reports may conflict. For instance, if one SR corresponds to an L1 measurement report and another SR corresponds to an L1 measurement report, their time-domain and / or frequency-domain resources may overlap. The terminal can then select the SR with the higher priority based on the priority relationship of the conflicting SRs, for example, by determining that the resources of the higher-priority SR are available (e.g., valid). Alternatively, the terminal can randomly select an SR corresponding to an L1 measurement report to send.

[0187] Taking the example of a terminal selecting the SR with the higher priority based on the priority relationship of conflicting L1 measurement reports, the following is an example: For instance, the network device provides multiple L1 measurement reporting configurations for the terminal, such as L1 measurement reporting configuration-1 and L1 measurement reporting configuration-2. The SR-1 corresponding to the L1 measurement report based on L1 measurement reporting configuration-1 has a higher priority than the SR-2 corresponding to the L1 measurement report based on L1 measurement reporting configuration-2. Therefore, if SR-1 and SR-2 conflict, the terminal can choose to send SR-1 on the conflicting resource.

[0188] In some embodiments, the communication control method further includes: when the L1 measurement report and the first information are sent through the same transmission unit, and the size of the transmission unit is smaller than the sum of the sizes of the L1 measurement report and the first information, determining whether to perform the L1 measurement report through the transmission unit or to send the first information through the transmission unit based on the priority relationship between the L1 measurement report and the first information.

[0189] When the terminal determines that the L1 measurement report (which can also be described as the MAC CE used for L1 measurement report) and the first information are sent through the same transmission unit, it can determine whether the size of the transmission unit is less than the sum of the sizes of the L1 measurement report and the first information. If it is less than the sum of the sizes of the L1 measurement report and the first information, it can perform L1 measurement report or send the first information through the transmission unit according to the priority relationship between the L1 measurement report and the first information.

[0190] For example, L1 measurement reports are carried in the MAC CE, which is sent with the first information via the same data unit, such as the MAC PDU (Protocol Data Unit).

[0191] Because the size of a data unit (e.g., size, which represents the amount of data it can carry) is limited, if the size of the data unit is smaller than the sum of the sizes of the L1 measurement report and the first information, the L1 measurement report and the first information cannot be sent together through the data unit. The terminal can perform L1 measurement reporting or send the first information through the transmission unit according to the priority relationship between the L1 measurement report and the first information.

[0192] For example, the first information includes at least one of the following:

[0193] Ordinary data (e.g., data from other logical channels besides uplink CCCH (Common Control Channel) data);

[0194] Fill in data (e.g., Padding BSR (Buffer Status Report));

[0195] Connection failure indication signaling;

[0196] Cache indication signaling (e.g., BSR MAC CE);

[0197] Terminal identification signaling (e.g., C-RNTI (Cell Radio Network Temporary Identity) MAC CE);

[0198] Power reporting signaling (e.g., PHR (Power Headroom Report) MAC CE).

[0199] For example, the "connection failure indication signaling" includes at least one of the following:

[0200] Beam failure recovery indication signaling (e.g., BFR MAC CE)

[0201] Channel access failure indication signaling (e.g., LBT (Listen Before Talk) failure MAC CE)

[0202] For example, the priority of the SR corresponding to L1 measurement reporting and the first information may include at least one of the following:

[0203] MAC CE used for L1 measurement reporting has higher priority than ordinary data;

[0204] MAC CE used for L1 measurement reporting has higher priority than filler data;

[0205] The MAC CE used for L1 measurement reporting has a lower priority than the connection failure indication signaling;

[0206] MAC CE used for L1 measurement reporting has a lower priority than cached indication signaling;

[0207] The MAC CE used for L1 measurement reporting has a lower priority than terminal identification signaling;

[0208] The MAC CE used for L1 measurement reporting has a lower priority than the power reporting signaling.

[0209] For example, the MAC CE used for L1 measurement reporting has a higher priority than the padding data. In this case, when the MAC CE used for L1 measurement reporting and the padding data need to be sent in the same MAC PDU, but the size of the MAC PDU is smaller than the sum of the sizes of the MAC CE used for L1 measurement reporting and the padding data, the terminal can determine to carry the MAC CE used for L1 measurement reporting in the MAC PDU.

For example, step S201 may be implemented as a standalone embodiment, step S202 may be implemented as a standalone embodiment, and step S201+S202 may be implemented as a standalone embodiment, but is not limited thereto.

[0212] In some embodiments, step S201 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0213] In some embodiments, step S202 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0227] In some embodiments, if the first condition is not met, the apparatus further includes: a sending module configured to perform L1 measurement reporting when there are available uplink resources for L1 measurement reporting, without triggering SR reporting corresponding to the L1 measurement reporting.
