[0029] The following will clearly and completely describe the technical solutions of this disclosure in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of this disclosure, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0030] It should be noted that in this disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this disclosure as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0031] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0032] In the description of this disclosure, unless otherwise specified, " / " means "or." For example, A / B can mean A or B. "And / or" in this document simply describes an association relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can mean: A exists alone, A and B exists simultaneously, and B exists alone. Furthermore, "at least one" means one or more, and "a plurality" means two or more.

[0033] In the related art, for terminals that support higher frequencies (for example, frequency range 2 (FR2) band), their hardware configuration can be configured with multiple antenna panels. This type of terminal can support a multi-antenna panel mode (multi-antenna panel mode) in which multiple antenna panels work simultaneously, and can also support a single-antenna panel mode (single-antenna panel mode) in which one antenna panel works. The terminal can determine whether to use a single antenna panel mode or a multi-antenna panel mode based on its own capabilities. For example, when it is determined that the multiple signals sent by the base station are downlink signals in different beam directions, the terminal can choose to receive multiple downlink signals through a multi-antenna panel mode. When it is determined that the downlink signal sent by the base station is in the same beam direction, the terminal can choose to receive the downlink signal through a single antenna panel mode.

[0034] In some embodiments, the terminal may send user equipment assistance information (UE assistance information, UAI) to the base station to indicate to the base station the antenna panel mode that the terminal expects to use. Take the UAI sent by the terminal to the base station as the preference to single-antenna panel mode signaling as an example. After the terminal sends the UAI to the base station, the terminal determines that the single antenna panel mode needs to be used and needs to switch from the multi-antenna panel mode to the single antenna panel mode. However, after receiving the UAI, the base station may not stop scheduling or sending signals in multiple beam directions, but still determine whether the subsequent scheduled and reconfigured signals are signals in multiple different beam directions based on the base station's own decision. That is to say, after the base station receives the UAI, the base station may still send signals in multiple different beam directions to the terminal. In this case, the terminal cannot receive multiple downlink signals (such as the signals in the multiple different beam directions) that overlap in the time domain through a single antenna panel, which will result in reduced working efficiency of the terminal.

[0035] To solve the above technical problems, some embodiments of the present disclosure provide a communication method, in which the first node only receives one downlink signal from multiple downlink signals overlapping in the time domain from the second node when a single signal reception mode is expected to be used, instead of receiving all multiple signals, thereby avoiding the problem of reduced working efficiency of the terminal due to the inability to receive multiple downlink signals when a single antenna panel mode is expected to be used.

[0036] The communication method provided by some embodiments of the present disclosure may be applied to a communication system as shown in FIG1 . As shown in FIG1 , the communication system includes a first node 101 and a second node 102 .

[0037] A first node 101 is in communication with a second node 102. The first node 101 may be a user equipment or terminal. The second node 102 may be a base station. FIG1 illustrates the first node 101 as a terminal and the second node 102 as a base station.

[0038] In actual applications, the second node 102 may send a single downlink signal or multiple downlink signals that overlap in the time domain to the first node 101. The first node 101 may receive a single downlink signal sent by the second node 102 in a single-Rx mode or multiple downlink signals that overlap in the time domain sent by the second node 102 in a multi-Rx mode.

[0039] In some embodiments of the present disclosure, the second node 102 may send multiple downlink signals that overlap in the time domain to the first node 101. When the first node 101 desires to use a single signal reception mode, it may receive one downlink signal, i.e., the first downlink signal, from the multiple downlink signals that overlap in the time domain sent by the second node 102. In this way, when the first node 101 desires to use a single signal reception mode and is faced with multiple downlink signals that overlap in the time domain, it may determine to receive one of the multiple downlink signals, thereby resolving the technical issue of a terminal being unable to receive multiple downlink signals that overlap in the time domain using a single antenna panel.

[0040] It should be noted that Figure 1 is only an exemplary framework diagram. The number of devices included in Figure 1 and the names of each device are not limited. In addition to the devices shown in Figure 1, the communication system may also include other devices, such as a core network.

[0041] The application scenarios of some embodiments of the present disclosure are not limited. The system architecture and business scenarios described in some embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of some embodiments of the present disclosure and do not constitute a limitation on the technical solutions provided by some embodiments of the present disclosure. Those skilled in the art will appreciate that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by some embodiments of the present disclosure are equally applicable to similar technical problems.

[0042] The communication methods provided by some embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0043] The communication method provided in some embodiments of the present disclosure may be applied to the first node 101 in the communication system shown in Figure 1. Figure 2 shows a flow chart of a communication method. As shown in Figure 2, the communication method includes S201.

[0044] In S201 , a first node receives a first downlink signal from a second node.

[0045] The first downlink signal is one of multiple downlink signals sent by the second node; the multiple downlink signals overlap in the time domain. Time domain overlap includes complete overlap and / or partial overlap. The single-signal reception mode includes a single-antenna panel mode or a single RF chain mode. Correspondingly, the multi-signal reception mode includes a multi-antenna panel mode or a multi-RF chain mode.

[0046] In some embodiments, the multiple signals overlapping in the time domain may be signals in multiple different beam directions sent by the base station to the terminal.

[0047] In some implementations, the second node may send multiple downlink signals that overlap in time domains (or time domain resources) to the first node. In this case, when the first node expects to use a single-signal reception mode, it selects a downlink signal from the multiple downlink signals that overlap in time domains sent by the second node as the first downlink signal to be received, and the first node receives the first downlink signal through the single-signal reception mode. In this way, when the first node expects to use a single-signal reception mode, it can determine to receive only one downlink signal instead of all downlink signals, thereby avoiding the problem of reduced work efficiency of the terminal due to the inability to receive multiple downlink signals when the terminal expects to use a single-signal reception mode.

[0048] In one implementation, when the second node determines that the first node expects to switch from a multi-signal reception mode to a single-signal reception mode (for example, the second node receives the UAI of the first node), the second node may still send or schedule multiple downlink signals that overlap in the time domain to the first node. At this time, when the first node detects multiple downlink signals sent by the second node, the first node may choose to switch to a single-signal reception mode, or it may still maintain a multi-signal reception mode, and the present disclosure does not limit this. When the first node still maintains a multi-signal reception mode, the first node may only receive the first downlink signal among the multiple downlink signals, or it may receive all the multiple downlink signals through multiple antenna panels (or multiple RF chains).

[0049] In some embodiments of the present disclosure, the multiple downlink signals sent by the second node to the first node may include different types of signals, which are described below respectively.

[0050] In some embodiments, the multiple downlink signals include a channel transmission signal; or, the multiple downlink signals include: a channel transmission signal and a reference signal; or, the multiple downlink signals include: a reference signal.

[0051] The channel transmission signal is a downlink signal transmitted over the physical downlink shared channel and / or the physical downlink control channel. The reference signal is any of the following: a periodic reference signal, an aperiodic reference signal, or a semi-persistent reference signal. The reference signal is a channel state information reference signal or a synchronization signal block.

[0052] It can be understood that the downlink signal transmitted by the physical downlink shared channel and / or the physical downlink control channel may be a signal used for service transmission, the reference signal may be a signal used for measurement, or the reference signal may be a pilot signal.

[0053] Since the multiple signals may include downlink signals transmitted based on the physical downlink shared channel and / or the physical downlink control channel, the first node may receive the downlink signal transmitted based on the physical downlink shared channel, and / or the first node may receive the downlink signal transmitted based on the physical downlink control channel.

[0054] The first node receiving a downlink signal transmitted based on a physical downlink control channel can also be referred to as: the first node receiving a physical downlink control channel (PDCCH). The first node receiving a downlink signal transmitted based on a physical downlink shared channel can also be referred to as: the first node receiving a physical downlink shared channel (PDSCH). The PDSCH can be at least one of the following: a PDSCH dynamically scheduled by downlink control information (DCI), a PDSCH semi-statically configured by radio resource control (RRC) signaling dynamically activated by DCI, or a PDSCH semi-statically configured by radio resource control (RRC) signaling dynamically activated by a media access control control element (MAC control element, MAC CE).

[0055] The reference signal (RS) includes at least one of the following: a periodic synchronization signal block (SS block, SSB) configured by RRC signaling, a channel state information-reference signal (CSI-RS) configured by RRC signaling, a semi-persistent CSI-RS configured by RRC signaling activated by MAC CE, and an aperiodic CSI-RS dynamically scheduled by DCI.

[0056] In some embodiments of the present disclosure, the first node may determine the first downlink signal in a variety of ways. For example, the first node may determine the signal with the highest priority among multiple downlink signals as the first downlink signal; or the first node may determine the signal that the first node first detects among multiple downlink signals as the first downlink signal; or the first node may determine the signal that the second node first schedules among multiple downlink signals as the first downlink signal. In other words, the first downlink signal satisfies at least one of the following conditions: the signal with the highest priority among multiple downlink signals; the signal that the first node first detects among multiple downlink signals; the signal that the second node first schedules among multiple downlink signals; or the signal with the earliest starting time domain resource among multiple downlink signals.

[0057] As an example, taking multiple downlink signals including downlink signal A and downlink signal B as an example, the time domain resources of downlink signal A are symbol 3, symbol 4, and symbol 5, and the time domain resources of downlink signal B are symbol 4, symbol 5, and symbol 6. Since the starting time domain resource of downlink signal A is symbol 3, and the starting time domain resource of downlink signal B is symbol 4, the starting time domain resource of downlink signal A is earlier than the starting time domain resource of downlink signal B.

[0058] In some embodiments of the present disclosure, when the first downlink signal is the signal with the highest priority among multiple downlink signals, the first node can determine the priorities of the multiple downlink signals in various ways. The following describes various ways in which the first node determines the priorities of the multiple downlink signals.

[0059] In some embodiments, the priorities of multiple downlink signals are determined based on at least one of the following methods: based on system pre-configured priorities; based on priority configuration information sent by the second node; based on the control resource set (CORESET) sequence number for scheduling multiple downlink signals; based on resource indexes of multiple downlink signals.

[0060] If the priorities of multiple downlink signals are determined based on system preconfigured priorities, upon detecting multiple downlink signals, the first node may determine the first downlink signal based on locally stored preconfigured priority information. Alternatively, if the priorities of multiple downlink signals are semi-statically configured by a second node, the second node may send priority configuration information to the first node. The first node may then receive the priority configuration information and determine the priorities of the multiple downlink signals based on the priority configuration information.

[0061] Alternatively, when the priorities of multiple downlink signals are determined based on the CORESET numbers of the multiple downlink signals, after detecting multiple downlink signals, the first node can determine the priority of each downlink signal based on the CORESET number (or index) of each downlink signal.

[0062] Alternatively, in the case where the downlink signal is a reference signal, the first node may determine the priority of the downlink signal based on a resource index of the downlink signal.

[0063] The smaller the CORESET sequence number of the target downlink signal, the higher the priority of the target downlink signal, and the target downlink signal is any one of multiple downlink signals. The smaller the resource index of the target downlink signal, the higher the priority of the target downlink signal, and the target downlink signal is any one of multiple downlink signals.

[0064] In some embodiments of the present disclosure, in combination with the embodiment in which the multiple downlink signals include multiple types of downlink signals, the priorities of different types of downlink signals may be different. The priorities of multiple types of downlink signals will be described below.

[0065] In some embodiments, the priorities of multiple downlink signals satisfy at least one of the following: the priority of the non-semi-periodic reference signal is higher than the semi-persistent reference signal, or the priority of the non-semi-periodic reference signal is lower than the semi-persistent reference signal; the priority of the semi-persistent reference signal is higher than the periodic reference signal, or the priority of the semi-persistent reference signal is lower than the periodic reference signal; the priority of the synchronization signal block is higher than the channel state information reference signal, or the priority of the synchronization signal block is lower than the channel state information reference signal; the priority of the channel state information reference signal configured with repeated shutdown is higher than the channel state information reference signal configured with repeated activation, or the priority of the channel state information reference signal configured with repeated shutdown is lower than the channel state information reference signal configured with repeated activation; in the multiple downlink signals In the case where the priority is determined based on the CORESET number of scheduling multiple downlink signals, the smaller the CORESET number of the scheduling downlink signal, the higher the priority of the downlink signal, or, in the case where the priority of multiple downlink signals is determined based on the CORESET number of scheduling multiple downlink signals, the smaller the CORESET number of the scheduling downlink signal, the lower the priority of the downlink signal; in the case where the priority of multiple downlink signals is determined based on the resource index of multiple downlink signals, and the downlink signal is a reference signal, the smaller the resource index of the reference signal, the higher the priority of the reference signal, or, in the case where the priority of multiple downlink signals is determined based on the resource index of multiple downlink signals, and the downlink signal is a reference signal, the smaller the resource index of the reference signal, the lower the priority of the reference signal.

[0066] It can be understood that a CSI reference signal configured with repetition OFF is a non-repetitive CSI reference signal, and a CSI reference signal configured with repetition ON is a repetitive CSI reference signal.

[0067] In some embodiments of the present disclosure, in combination with the above-mentioned embodiments, the following describes how the first node determines the first downlink signal in various situations where the multiple downlink signals include multiple types of signals. The various situations are: situation 1, where the multiple downlink signals include channel transmission signals; situation 2, where the multiple downlink signals include channel transmission signals and reference signals; and situation 3, where the multiple downlink signals include reference signals. The following details:

[0068] Case 1: Multiple downlink signals include a channel transmission signal.

[0069] That is to say, the multiple downlink signals include downlink signals transmitted based on the physical downlink shared channel and / or the physical downlink control channel.

[0070] Taking the example of multiple downlink signals including two downlink signals, the multiple downlink signals may include: a signal transmitted based on a PDCCH and a signal transmitted based on a PDCCH; or a signal transmitted based on a PDCCH and a signal transmitted based on a PDSCH; or a signal transmitted based on a PDSCH and a signal transmitted based on a PDSCH. In this case, the first node determines the first downlink signal from the two downlink signals in the following manner:

[0071] (1) The first node determines the first downlink signal based on the priorities of the two downlink signals.

[0072] As an example, the priority of the downlink signal may be the priority of the control resource set index (CORESET index) corresponding to the downlink signal. At this time, when receiving the downlink signal, the first node receives the downlink signal transmitted by the PDCCH carried in the CORESET with the highest priority. The priority of the CORESET index may be a pre-configured CORESET index priority, or may be a CORESET index priority semi-statically configured by the second node.

[0073] (2) The first node determines the first downlink signal based on the time domain sequence of the two downlink signals.

[0074] For example, the first node determines the first detected signal based on the PDCCH transmission as the first downlink signal. Alternatively, the first node determines the first scheduled signal based on the PDSCH transmission by the second node as the first downlink signal.

[0075] After the first node determines the first downlink signal, the first node will no longer receive signals transmitted by PDSCH / PDCCH with overlapping time domain resources.

[0076] Case 2: Multiple downlink signals include channel transmission signals and reference signals.

[0077] Taking the example of multiple downlink signals including two downlink signals, the multiple downlink signals may include a signal and a reference signal transmitted based on a PDCCH, or a signal and a reference signal transmitted based on a PDSCH. When the reference signal is at least one of an RRC signaling configured reference signal, a MAC CE configured reference signal, or a DCI scheduling reference signal, the channel transmission signal and the reference signal that have time domain overlap need to be received by the first node.

[0078] (3) The first node determines the first downlink signal based on the priority of the two downlink signals: The priority between the channel transmission signal and the reference signal may be a priority preconfigured by the system, so that the first node can determine the first downlink signal based on the locally stored priority. For example, the priority of the reference signal may be higher than the priority of the channel transmission signal.

[0079] Alternatively, the second node may semi-statically configure the priority between the channel transmission signal and the reference signal. Afterwards, the second node may send priority configuration information to the first node via second indication information, thereby enabling the first node to determine the first downlink signal based on the priorities of the multiple downlink signals.

[0080] Case 3: Multiple downlink signals include a reference signal.

[0081] Taking the case where the multiple downlink signals include two downlink signals as an example, the multiple downlink signals may include two reference signals.

[0082] (4) The first node determines the first downlink signal based on the priorities of the two downlink signals: the priorities among the multiple reference signals may be preconfigured priorities. In this way, the first node may determine the first downlink signal based on the priorities stored locally. For example, the priority of a non-semi-periodic reference signal is higher than that of a semi-persistent reference signal; the priority of a semi-persistent reference signal is higher than that of a periodic reference signal; the priority of a synchronization signal block is higher than that of a channel state information reference signal; the priority of a channel state information reference signal configured with repeated off is higher than that of a channel state information reference signal configured with repeated on, etc.

[0083] In some embodiments of the present disclosure, a first node may determine that it desires to use a single-signal reception mode in various scenarios, including: Scenario 1: The first node sends an indication to the second node that it desires to receive signals using the single-signal reception mode. Scenario 2: The second node indicates to the first node that the Transmission Configuration Indication (TCI) state is no longer a beam pair. These are described in detail below:

[0084] Scenario 1: The first node sends indication information to the second node indicating that it desires to receive signals in the single signal receiving mode.

[0085] Figure 3 shows another flow chart of a communication method. In combination with Figure 2, as shown in Figure 3, before the above S201, the method provided in some embodiments of the present disclosure further includes S301.

[0086] In S301, the first node sends first indication information to the second node.

[0087] The first indication information is used to indicate that the first node desires to use the single signal receiving mode.

[0088] As an example, the first indication information may be preference to single-Rx mode UAI signaling sent by the first node to the second node.

[0089] It is understandable that, when the second node receives the first indication information sent by the first node and switches the second node's multi-data Rx scheduling to single-data Rx scheduling, the second node will not send downlink signals that overlap in the time domain to the first node. At this time, the first node can receive the non-time-domain overlapping downlink signals sent by the second node through the single-signal reception mode.

[0090] Multi-data reception scheduling is a method in which the second node sends multiple downlink signals that overlap in time domain to the first node, and single-data reception scheduling is a method in which the second node sends multiple downlink signals that overlap in time domain to the first node.

[0091] In one implementation, when the first node expects to use a single-signal receiving mode and the signal sent by the second node is still a plurality of downlink signals overlapping in the time domain, if the first node has not switched to the single-signal receiving mode at this time, the first node can maintain the current multi-signal receiving mode and continue to use the multi-signal receiving mode to receive multiple downlink signals overlapping in the time domain.

[0092] Accordingly, after the first node desires to use the single signal reception mode, the first node may switch from the multi-signal reception mode to the single signal reception mode. In this case, when the first node detects multiple downlink signals that overlap in the time domain, the first node may switch from the multi-signal reception mode to the single signal reception mode, thereby receiving the first downlink signal in the single signal reception mode.

[0093] In one implementation, the second node may send multiple downlink signals that overlap in the time domain to the first node before sending the first indication information to the first node; or, the second node may also send multiple downlink signals that overlap in the time domain to the first node after the first node sends the first indication information. This disclosure does not limit this.

[0094] Scenario 2: The second node indicates to the first node that the transmission configuration indication state is no longer a beam pair.

[0095] In one implementation, when the second node determines that it no longer uses multiple beams to transmit signals to the first node, the second node sends a message to the first node indicating that the transmission configuration indication state may no longer be a single beam pair. After receiving the message, the first node may determine that it desires to use the single signal reception mode.

[0096] In some embodiments, another flow chart of a communication method is shown in Figure 4. In combination with Figure 2, as shown in Figure 4, in the above S201, the first node receiving the first downlink signal from the second node includes S401.

[0097] In S401, a first node receives a first downlink signal using a first antenna panel among a plurality of antenna panels of the first node.

[0098] The first antenna panel is an antenna panel when the first node works in a single antenna panel mode.

[0099] In some implementations, when receiving the first downlink signal, the first node can receive the first downlink signal through a single antenna panel mode, that is, the first node can receive the first downlink signal based on the first antenna panel among multiple antenna panels, thereby achieving the reception of one downlink signal among multiple downlink signals overlapping in the time domain.

[0100] In some embodiments, another flow chart of a communication method is shown in Figure 5. In combination with Figure 2, as shown in Figure 5, in the above S201, the first node receiving the first downlink signal from the second node includes S501.

[0101] In S501 , a first node receives a first downlink signal using a first radio frequency chain among a plurality of radio frequency chains of the first node.

[0102] The first radio frequency chain is a radio frequency chain in which the first node operates in a single radio frequency chain mode.

[0103] In some implementations, when receiving the first downlink signal, the first node can receive the first downlink signal through a single RF chain mode, that is, the first node can receive the first downlink signal based on the first RF chain among multiple RF chains, thereby achieving the reception of one downlink signal among multiple downlink signals overlapping in the time domain.

[0104] The communication method provided in some embodiments of the present disclosure may also be applied to the second node 102 in the communication system shown in Figure 1. Figure 6 shows another flow chart of a communication method. As shown in Figure 6, the communication method includes S601.

[0105] In S601, the second node sends a first downlink signal to the first node.

[0106] The first downlink signal is one of multiple downlink signals sent by the second node. The multiple downlink signals overlap in the time domain.

[0107] It can be understood that, for the description of the second node sending the first downlink signal and the description of multiple downlink signals to the first node, reference can be made to S201 and S301, and this disclosure will not elaborate on this.

[0108] In some embodiments of the present disclosure, the terminal may feed back the demand for a measurement interval (e.g., a gap) to the base station, thereby instructing the base station to perform various measurements of the cell in the measurement interval. In some embodiments, the measurement interval also includes a measurement interval type with a shorter interruption time, namely, a network controlled small gap (NCSG). NCSG can be applied to the measurement of a deactivated secondary cell (deactivated secondary cell, deactivated SCell), and can also be applied to the intra-frequency cell measurement, inter-frequency cell measurement of a neighboring cell, and the intra-frequency measurement of a serving cell. A gap is a measurement interval of a common type, and NCSG is a measurement interval different from a gap type.

[0109] The terminal can use signaling to feedback the base station's requirements for gaps and NCSGs in the same and different frequencies. However, the requirements for measurement intervals fed back by the terminal to the base station cannot adapt to the measurement requirements of the cell in various states, which will reduce the efficiency of cell measurement.

[0110] In this scenario, in combination with the communication system shown in FIG1 , in actual applications, the first node 101 may provide feedback on the measurement interval requirement of a neighboring cell, an intra-frequency cell, or an inter-frequency cell to the second node 102. The second node 102 may receive the measurement interval requirement and determine whether to configure a gap or NCSG for the first node 101 to assist the first node in performing cell measurements, such as channel measurements, mobility measurements, and radio resource management measurements.

[0111] To address the problem that the measurement interval requirements fed back by the terminal to the base station cannot adapt to the measurement requirements of the cell in various states, which will lead to reduced efficiency of cell measurement, some embodiments of the present disclosure further provide a communication method, which can also be applied to the first node 101 in the communication system shown in Figure 1. Figure 7 shows another flow chart of a communication method. As shown in Figure 7, the communication method includes S701.

[0112] In S701, the first node sends second indication information to the second node.

[0113] The second indication information includes a measurement interval requirement of the target cell in an activated state and / or a measurement interval requirement of the target cell in an inactivated state.

[0114] In some implementations, the first node may provide feedback to the second node on the target cell's measurement interval (also known as a measurement gap) requirements in an activated state and / or the measurement interval requirements in a deactivated state. The second node may then better assist the first node in measuring the target cell based on the target cell's state and the measurement interval requirements provided by the first node. This allows the first node to better adapt to the various states of the target cell when performing cell measurements, thereby improving the efficiency of cell measurements.

[0115] In one implementation, the target cell may be the cell where the first node is located.

[0116] In some embodiments, the measurement interval includes: a measurement interval gap and a small interval NCSG under network control. The measurement interval for the first node to feedback the requirement to the second node can be a gap or an NCSG, thereby adapting to diverse measurement requirements.

[0117] In some embodiments, the measurement interval requirement includes any one of the following: gap required, NCSG required, and neither gap nor NCSG required.

[0118] In some implementations, the measurement interval requirement may include requiring a gap so that the second node configures a gap, thereby allowing the first node to perform measurements in the gap; or, the measurement interval requirement may include requiring NCSG so that the second node configures NCSG, thereby allowing the first node to perform measurements in NCSG; or, the measurement interval requirement may include requiring neither a gap nor NCSG, so that the second node does not need to configure a gap or NCSG, and the first node can perform measurements without the assistance of a gap or NCSG.

[0119] The communication method provided in some embodiments of the present disclosure may also be applied to the second node 102 in the communication system shown in Figure 1. Figure 8 shows another flow chart of a communication method. As shown in Figure 8, the communication method includes the following S801.

[0120] In S801, the second node receives second indication information sent by the first node.

[0121] The second indication information includes a measurement interval requirement of the target cell in an activated state and / or a measurement interval requirement of the target cell in an inactivated state.

[0122] In one implementation, the second node avoids scheduling data to the first node during the measurement interval sent by the first node. Alternatively, the second node may send at least one of the following to the first node based on the measurement interval requirement: measurement configuration information, gap configuration information, or NCSG configuration information, so that the first node can perform measurements based on the sent information.

[0123] It can be understood that, for the description of the second node receiving the second indication information sent by the first node, the description of the measurement interval, and the description of the measurement interval requirement, reference can be made to the description of S601, which will not be described in detail in this disclosure.
