Abstract
Description
Technical Field
[0001] The present application relates to the field of communication technology, and in particular to a communication method and device, and a computer-readable storage medium. Background Art
[0002] In the New Radio (NR) system, the terminal device is in a connected state, and the network device configures the terminal device with multiple frequency measurements, such as same-frequency measurement and different-frequency measurement, and the different-frequency measurement can have multiple frequency points.
[0003] Usually, for heterodyne measurements, the terminal device needs to use gaps (GAPs) for measurement. For example, if the GAP is configured with a period of 40 milliseconds (ms) or 80 ms, the heterodyne is measured within a time length of 3 ms starting from the sixth time slot in the period. There are many variations in the configuration parameters of GAP, such as the starting position and duration in the period. In the GAP, the terminal device tunes the RF transceiver to the heterodyne frequency, and then measures the neighboring cells on the heterodyne frequency. This requires a certain amount of processing time. The terminal device may not be able to fully measure all heterodyne frequencies within a measurement cycle, that is, it can only measure some frequencies. The terminal device measures all frequencies to be measured over a long period of time. When the terminal device finds that the reporting conditions of a certain measurement frequency are met, the terminal device triggers the reporting of a measurement report. The measurement report contains the measurement results on the measurement frequency, usually the measurement results of the strongest several cells. For event-triggered measurement reports (measurement reports triggered because the measurement event is met), the network usually initiates a handover process.
[0004] However, since a measurement report is usually a measurement report of a neighboring cell on a frequency, the network may not be able to make a good handover decision when making a handover decision. For example, the terminal device reports the measurement report of the neighboring cell on frequency F1 at time T1, but the cell load of the neighboring cells on frequency F1 is relatively high. At this time, it is likely that the new cell will need to initiate a handover for the terminal device again soon, resulting in frequent cell handovers for the terminal device.

[0045] The communication systems to which the embodiments of the present application are applicable include, but are not limited to, Long Term Evolution (LTE) systems, fifth-generation (5G) systems, new wireless (NR) systems, and future evolution systems or multiple communication fusion systems. Among them, the 5G system can be a non-standalone (NSA) 5G system or a standalone (SA) 5G system.

[0046] This application mainly relates to the communication between terminal equipment and network equipment. Among them:
[0047] The network device in the embodiment of the present application may also be referred to as an access network device, for example, it may be a base station (BS) (also referred to as a base station device), and the network device is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, in the second-generation (2G) network, the equipment that provides base station functions includes the base transceiver station (BTS), in the third-generation (3G) network, the equipment that provides base station functions includes the node B (NodeB), and in the fourth-generation (4G) network, the equipment that provides base station functions includes the evolved node B (eNB).

The network devices in the embodiments of the present application also include devices that provide base station functions in future new communication systems, etc.
[0048] The terminal equipment in the embodiments of the present application may refer to various forms of access terminals, user units, user stations, mobile stations, mobile stations (Mobile Station, MS), remote stations, remote terminals, mobile devices, user terminals, wireless communication devices, user agents or user devices. The terminal equipment may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolving Public Land Mobile Network (PLMN), etc., which is not limited in the embodiments of the present application. The terminal equipment may also be referred to as User Equipment (UE), a terminal, etc.
[0049] As described in the background art, since a measurement report is usually a measurement report of a neighboring cell on a frequency, when the network makes a handover decision, the network may not be able to make a good handover decision.
[0050] The technical solution of the present application carries the measurement status of the second measurement frequency in the measurement report of the first measurement frequency, so that the network equipment can promptly learn the measurement status of the second measurement frequency, thereby being able to make a comprehensive switching decision, so that the terminal equipment can switch to the cell at the better measurement frequency, avoiding frequent cell switching of the terminal equipment and improving communication performance.
[0051] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0052] See also Figure 1 The method provided in this application specifically includes the following steps:
[0053] Step 101: In response to a measurement result of a first measurement frequency satisfying a first reporting condition, a terminal device reports a measurement report, wherein the measurement report includes the measurement result of the first measurement frequency and the measurement status of the second measurement frequency.
[0054] It should be pointed out that the serial numbers of the steps in this embodiment do not limit the execution order of the steps.
[0055] It is understandable that, in a specific implementation, the communication method can be implemented in the form of a software program, which runs in a processor integrated inside a chip or a chip module. The method can also be implemented in the form of software combined with hardware, which is not limited in this application.
[0056] Specifically, the terminal device establishes a Radio Resource Control (RRC) connection with the network device, and the terminal device is in a connected state. The network device configures measurement for the terminal device according to the Measurement Identity (MeasId), and a measurement identity is associated with a Measurement Object Identity (MeasObjectId) and a Report Configuration Identity (ReportConfigId).
[0057] The measurement object may specifically be a measurement frequency point or a measurement frequency. Reporting configuration refers to reporting conditions, which may specifically be periodic reporting conditions or event-based reporting conditions. Measurement events may be A3 (the signal quality of the neighboring cell is higher than that of the serving cell by a preset offset), A4 (the signal quality of the neighboring cell is higher than the preset threshold), A5 (the signal quality of the serving cell is lower than the preset threshold 1, and the signal quality of the neighboring cell is higher than the preset threshold 2). Event-based reporting conditions are usually configured to satisfy the trigger duration (TimeToTrigger), that is, the event needs to be continuously satisfied for a duration greater than or equal to the trigger duration before the terminal device triggers the reporting of the measurement report. The trigger duration may specifically be 0, 40ms, 80ms, etc.
[0058] After obtaining multiple measurement identifiers (ie, measurement tasks), the terminal device starts measuring neighboring cells.
[0059] In this embodiment, the network device configures a corresponding measurement event and a first reporting condition for the first measurement frequency, and configures a corresponding measurement event and a second reporting condition for the second measurement frequency, wherein the second reporting condition includes a first trigger duration. The first measurement frequency is different from the second measurement frequency.
[0060] When the measurement result of the first measurement frequency meets the first reporting condition, the terminal device reports a measurement report for the neighboring cells on the first measurement frequency. For example, the measurement report includes the measurement result of at least one cell with the strongest signal on the first measurement frequency.
[0061] Specifically, the first reporting condition may be the aforementioned periodic reporting condition or the event-based reporting condition.
[0062] Different from the measurement report in the prior art, the measurement report for the neighboring cell on the first measurement frequency also includes the measurement status of the second measurement frequency, so that the network equipment can promptly know the measurement status of the second measurement frequency, thereby being able to make a comprehensive switching decision, so that the terminal equipment can switch to the cell on the better measurement frequency, avoiding frequent cell switching of the terminal equipment and improving communication performance.
[0063] For example, the terminal device reports the measurement report of the neighboring cell on frequency F1 (i.e., the first measurement frequency) at time T1, but the cell loads of the neighboring cells on frequency F1 are relatively high. At this time, after switching, it is likely that the new cell will need to initiate switching for the terminal device again soon. Since the measurement report also includes the measurement status of frequency F2 (i.e., the second measurement frequency), for example, whether there are neighboring cells on frequency F2 that meet the triggering conditions of the measurement event, whether there are neighboring cells that meet the measurement event but do not meet the triggering duration, etc., and the load of the neighboring cells on frequency F2 is relatively low, the network device can clearly know through the measurement status of frequency F2 that the terminal device will soon trigger the measurement report on frequency F2, and the network device is likely to wait for a while in order to make a more reasonable switching decision after obtaining the measurement report on frequency F2.
[0064] The following describes in detail the specific measurement state and the second measurement frequency.
[0065] Embodiment 1: The measurement status includes first indication information, and the first indication information is used to indicate whether the measurement of the second measurement frequency has started.
[0066] In this embodiment, the following two situations are divided according to whether the terminal device starts measuring the second measurement frequency.
[0067] Case 1: The terminal device does not start measuring the second measurement frequency.
[0068] Please refer to Figure 2 In step 201, the measurement result of the first measurement frequency measured by the terminal device meets the first reporting condition, and the terminal device has not started measuring the second measurement frequency.
[0069] In step 202, the terminal device reports a measurement report.
[0070] In an embodiment, the measurement status of the second measurement frequency in the measurement report includes first indication information, where the first indication information is used to indicate that the measurement of the second measurement frequency has not started.
[0071] For example, the measurement status includes one bit, and the bit is 0, indicating that the measurement of the second measurement frequency has not started.
[0072] Furthermore, the measurement status may also include a first expected time for measuring the second measurement frequency, and / or a measurement period of the second measurement frequency. The first expected time may indicate how long it will take for the terminal device to start measuring the second measurement frequency. Specifically, the first expected time may be calculated by the difference between the current moment and the next measurement moment of the second measurement frequency.
[0073] For example, frequency F2 is an inter-frequency frequency, the measurement period is 40ms, and the inter-frequency is measured within a time length of 3ms starting from the 6th time slot in the period, then the terminal device can calculate the first expected time and carry the first expected time of frequency F2 in the measurement report for frequency F1. The current moment used when calculating the first expected time can be the moment corresponding to when the first measurement frequency meets the reporting conditions, or it can be the moment when the measurement result of the first measurement frequency is reported. For example, when the measurement result of the first measurement frequency is sent to the network device at a certain moment, this moment is used to calculate the first expected time.
[0074] For another example, the terminal device carries the first expected time and measurement period (40 ms) of frequency F2 in the measurement report for frequency F1.
[0075] Case 2: The measurement status includes one or more of the following: measurement of the second measurement frequency has started, and signal quality information of the cell on the second measurement frequency.
[0076] Please refer to Figure 3 In step 301, the measurement result of the first measurement frequency measured by the terminal device meets the first reporting condition, and the terminal device has started to measure the second measurement frequency.
[0077] In step 302, the terminal device reports a measurement report.
[0078] In this embodiment, the measurement status of the second measurement frequency in the measurement report includes first indication information, where the first indication information is used to indicate that the measurement of the second measurement frequency has started.
[0079] For example, the measurement state includes one bit, and the bit is 1, indicating that the measurement of the second measurement frequency has started.
[0080] Further, the measurement status includes signal quality information of the cell on frequency F2. Specifically, the signal quality information may include one or more of the following: a signal value of a neighboring cell on the second measurement frequency, a duration for the neighboring cell on the second measurement frequency to satisfy a measurement event, and an expected time for satisfying a second reporting condition, where the expected time indicates a difference between the above duration and a first trigger duration included in the second reporting condition.
[0081] For example, the reporting configuration of frequency F2 is to continuously meet event A3 for 80ms. When the measurement report of frequency F1 is triggered, the signal value of the neighboring area on frequency F2 continues to meet event A3 for 20ms. Then, the measurement status includes the signal value of the neighboring area 1 on frequency F2, the duration of 20ms, and the expected time of 60ms. Considering that there may be a certain deviation between the time when the terminal device reports the measurement report of the first measurement frequency and the time when the terminal device finds that the measurement result of the first measurement frequency meets the reporting conditions, for example, the time when the reporting condition is met is time slot n, and the time when the measurement report is reported is time slot n+2, therefore, when the terminal device reports the measurement status of the neighboring area on the second measurement frequency, the expected time to meet the second reporting condition is based on the measurement report reporting time, and how long it is expected to meet the second reporting condition. In practice, considering that the expected time is usually much larger than the above deviation value, a simple approach is to ignore the above deviation value.
[0082] Furthermore, multiple neighboring cells may be measured at the second measurement frequency and successively meet the measurement events. The duration for which the neighboring cells at the second measurement frequency in the measurement state meet the measurement event is based on the first neighboring cell that meets the measurement event entry conditions. The expected time for meeting the second reporting conditions in the measurement state is also calculated based on the first neighboring cell that meets the measurement event entry conditions.
[0083] Specifically, when the measurement result of the first measurement frequency meets the first reporting condition, and the terminal device needs to include the measurement status of the second measurement frequency in the measurement report, if the terminal device finds that the measurement status of the second measurement frequency has been reported within a period of time (such as within 40ms), the terminal device may not include the measurement status of the second measurement frequency in this measurement report; or if the measurement report has been triggered on the second measurement frequency, such as the neighboring area on the second measurement frequency meets the reporting condition and triggers the measurement report, the terminal device may not include the measurement status of the second measurement frequency in this measurement report. This can further reduce signaling overhead.
[0084] Embodiment 3: In the scenario of dual connection condition switching, the measurement status of the second measurement frequency includes the second expected time for the candidate cell on the second measurement frequency to meet the other switching condition when one of the primary cell switching condition (switching execution condition) and the primary and secondary cell switching condition (primary and secondary cell update execution condition) is met. The second expected time indicates the difference between the duration of the signal value of the candidate cell reaching the event entry condition included in the switching condition and the second trigger duration included in the switching condition.
[0085] In this embodiment, in order to improve the mobility performance, the conditional switching of dual connections is considered to be introduced: conditional handover (CHO), and conditional PSCell Addition (CPA) / Conditional PSCell Change (CPC). Among them, CHO is a conditional switch for the primary cell (Pcell), and CPA / CPC is a conditional update for the primary secondary cell (PScell). Strictly speaking, the PSCell conditional update is different from the conventional switch. This article also refers to the conditional update of the primary and secondary cells as conditional switching for the sake of simplicity. The conclusion reached recently is that when the CPA / CPC execution conditions are met but the CHO execution conditions are not met, the terminal device continues to evaluate the execution conditions of CHO and CPA / CPC. For CHO+CPC (configuring candidate primary cells and candidate primary secondary cells at the same time), execution is considered only when two conditions are met (when the CHO execution condition is met but the CPC execution condition is not met, if there is a conditional switching configuration with only the candidate primary cell configuration that meets the CHO condition or a CHO with a secondary cell group (SCG) configuration (the SCG included in the conditional switching configuration has no corresponding switching condition (ie, update condition)), the terminal device executes CHO or executes CHO with SCG, and the network side can handle this situation by providing appropriate configuration).
[0086] For example, the network device configures a candidate primary cell PCell1 or a candidate primary secondary cell PSCell1 on the second measurement frequency. Usually, PCell1 and PSCell1 are located at different frequencies. The primary and secondary cell switching condition corresponding to the PSCell1 configured by the network is that the signal quality of the candidate PSCell1 is 2db higher than that of the serving PSCell and needs to last for 80 milliseconds (ms); at time T1, PCell1 meets the corresponding primary cell switching condition, PSCell1 is 2db higher than the serving PSCell and lasts for 20ms. Then, the terminal device can record the following measurement status: signal value of PSCell1, difference 2db, duration 20ms, expected time 60ms.
[0087] Furthermore, the network device also configures the candidate primary cell PCell2 and the candidate primary and secondary cell PSCell2 on the two second measurement frequencies. The terminal device can also record the measurement status for the second group of cells (PCell2 and PSCell2). That is, when PCell2 meets the corresponding primary cell switching condition, the terminal device records one or more of the signal value, difference, duration, expected time, etc. of PSCell2 at time T1.
[0088] Furthermore, the measurement status further includes second indication information, where the second indication information is used to indicate whether the candidate cell on the second measurement frequency satisfies another measurement event of a switching condition.
[0089] In a specific example, at time T1, PCell1 meets the corresponding primary cell switching condition, and PSCell1 does not meet the corresponding primary and secondary cell switching condition. At this time, the measurement report can also include the identifier of PCell1, that is, the identifier of the cell that meets the primary cell switching condition.
[0090] Embodiment 4: In a cell switching scenario, which can specifically be a case of non-dual connection condition switching, the second measurement frequency is a frequency configured with a candidate primary cell or a candidate primary secondary cell, and the measurement status includes a third expected time for the candidate primary cell or the candidate primary secondary cell to meet the switching condition, and the third expected time indicates the difference between the duration of the signal value of the candidate primary cell or the candidate primary secondary cell reaching the event entry condition included in the switching condition and the third trigger duration included in the switching condition.
[0091] In this embodiment, when the terminal device reports the measurement report of the first measurement frequency, it also reports the measurement status of the second measurement frequency configured with the candidate cell. This is because the terminal device obtains the settings of the network device in advance, and the reported measurement report also carries the measurement status of the frequency configured with the candidate cell. The measurement status includes any one of the measurement value of the candidate cell, whether the measurement event entry condition corresponding to the switching condition is met, the duration when the measurement event entry condition corresponding to the switching condition is met, and the expected time to meet the switching condition.
[0092] Embodiment 5: The reporting configuration included in the measurement identifier to which the second measurement frequency belongs includes a timer T312.
[0093] For some measurement identifiers, the associated reporting configuration has a timer T312 (useT312 is set to True). When the terminal device triggers a measurement report for a measurement identifier and the reporting configuration included in this measurement identifier has a timer T312, and timer T310 is running, the terminal device needs to start timer T312. If the terminal device still does not receive a switching command when timer T312 times out, the terminal device will trigger RRC reconstruction or master cell group (MasterCell Group, MCG) failure processing (in dual connection configuration). Timer T310 is a parameter for wireless link detection. When timer T310 times out, the terminal device also needs to trigger RRC reconstruction.
[0094] In this embodiment, the measurement status of the second measurement frequency needs to be reported simultaneously with the measurement result of the first measurement frequency. In order to avoid unnecessary information, the terminal device can only report the measurement status of important frequencies at the same time. Then, the second measurement frequency can be a frequency with timer T312 in the reporting configuration included in the measurement identifier. A measurement identifier is associated with a measurement object and a reporting configuration. When timer T312 is configured in the reporting configuration, the measurement object associated with the measurement identifier is considered to be a frequency with timer T312.
[0095] In this embodiment, when the terminal device reports the measurement report of the first measurement frequency, it also reports the measurement status of the second measurement frequency configured with the timer T312, because the terminal device obtains the setting of the network device in advance, and the measurement report reported also carries the measurement status of the frequency configured with the timer T312. If the network device does not set the above timer T312 in advance, the terminal device does not need to carry the measurement status of the second measurement frequency in the measurement report reporting the first measurement frequency.
[0096] Embodiment 6: The reporting configuration of the measurement identifier to which the first measurement frequency belongs includes a timer T312.
[0097] Different from Embodiment 5, in the embodiment of the present invention, when reporting the measurement result of the first measurement frequency with timer T312 in the reporting configuration of the measurement identifier, the measurement status of the second measurement frequency can be reported simultaneously.
[0098] Specifically, the second measurement frequency is different from the first measurement frequency, and the reporting configuration of the measurement identifier to which the second measurement frequency belongs may or may not have the timer T312, and the present application does not impose any limitation on this.
[0099] Embodiment 7: The second measurement frequency is selected from at least one measurement frequency in the frequency configuration information.
[0100] Please refer to Figure 4In step 401, the network device sends frequency configuration information to the terminal device. The frequency configuration information includes at least one measurement frequency that needs to be reported simultaneously, and the second measurement frequency is selected from at least one measurement frequency.
[0101] Specifically, the frequency configuration information may include one frequency, or may include a frequency list, where the frequency list includes multiple frequencies.
[0102] In step 402, the terminal device reports a measurement report.
[0103] Further, in response to the measurement result of the first measurement frequency satisfying that the duration of the measurement event reaches the trigger duration, and the first measurement frequency does not belong to at least one measurement frequency, the terminal device carries the measurement status of the second measurement frequency when reporting the measurement report.
[0104] For example, the network device configures frequencies F3 and F4 as frequencies that need to be reported simultaneously. The measurement object (such as frequency F1) associated with the measurement identifier corresponding to the measurement report is not a measurement frequency that needs to be reported simultaneously or does not belong to the frequency list that needs to be reported simultaneously. The terminal device needs to carry the measurement status of F3 and F4 when reporting the measurement result of frequency F1.
[0105] For another example, if the measurement object associated with the measurement identifier corresponding to the currently triggered measurement report is frequency F3 or frequency F4, the terminal device does not need to additionally report the measurement status of other frequencies.
[0106] Furthermore, the frequency configuration information may also include a priority of at least one measurement frequency.
[0107] Specifically, a plurality of measurement frequencies may have a plurality of priorities.
[0108] Alternatively, the plurality of measurement frequencies may be divided into frequencies with priority and frequencies without priority according to priority.
[0109] Alternatively, the plurality of measurement frequencies may be divided into frequencies with higher priority and frequencies with lower priority according to priority.
[0110] In this embodiment, the priority of the second measurement frequency is higher than or equal to the priority of the first measurement frequency.
[0111] Embodiment 8: The second measurement frequency is selected from the frequency of the serving cell where the timer T310 is configured.
[0112] Usually, a terminal device in a connected state needs to detect the radio link status of the primary cell and the primary and secondary cells. The network device will configure a timer T310 for the terminal device to detect the radio link status. Whether the terminal device has run the timer T310 is unknown to the network device, so the network device may not be able to timely learn the actual situation of the radio link where the terminal device is located. Therefore, in this embodiment, if the terminal device has run the timer T310 (the timer T310 associated with the primary cell and / or the primary and secondary cells), the terminal device indicates whether the timer T310 is running when reporting the measurement report of the first measurement frequency. As a specific implementation method, the terminal device can include the indication information that the timer T310 has been run when reporting the measurement report of the first measurement frequency only when the timer T310 is running. At this time, the measurement status of the second measurement frequency is that the timer T310 corresponding to the primary cell and / or the primary and secondary cells is running (running).
