Description

Communication method, communication device, chip and computer-readable storage medium

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 6, 2024, with application number 202410173631.7 and application name “Communication Method, Communication Device, Chip and Computer-readable Storage Medium”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of communication technology, and in particular, to a communication method, a communication device, a chip, and a computer-readable storage medium. Background Art

[0003] Currently, network equipment configures a synchronization signal block measurement timing configuration (SMTC) window for terminal devices. Terminal devices measure synchronization signal blocks (SSBs) within the configured SMTC window and are unable to respond to the normal scheduling of network equipment, resulting in scheduling restrictions. Scheduling restrictions affect the system capacity of the communication system, and this impact is more significant in some business scenarios where the system capacity itself is relatively small. For example, in extended reality (XR) scenarios, the amount of transmitted data is large and sensitive to latency. Therefore, the system capacity in XR scenarios is relatively small, and scheduling restrictions will further reduce the system capacity in XR scenarios.

[0004] How to reduce scheduling constraints and increase system capacity has become one of the urgent issues to be solved. Summary of the Invention

[0005] The present application provides a communication method, a communication device, a chip, and a computer-readable storage medium, which can effectively reduce the scheduling restrictions of network equipment on user equipment, thereby improving system capacity.

[0006] In a first aspect, an embodiment of the present application provides a communication method, the method comprising:

[0007] Receive first information from a network device; the first information indicates a first SMTC window in at least one synchronization signal block measurement timing configuration SMTC window; the start time of at least one SMTC window is later than the reception time of the first information; monitor scheduling information in the first SMTC window, where the scheduling information is used to schedule the transmission of uplink and downlink channels and / or signals.

[0008] When implementing the method described in the first aspect, the terminal device may, based on the first information, not measure the SSB within a first SMTC window of at least one SMTC window, but instead monitor scheduling information from the network device. This allows the network device to normally schedule the terminal device for uplink and downlink channel and / or signal transmission within the first SMTC window, thereby reducing scheduling constraints and improving system capacity.

[0009] In one possible implementation, the value of the first information is a first value, indicating that at least one SMTC window is used to monitor scheduling information. In this way, the terminal device does not measure the SSB in each SMTC window of the at least one SMTC window, but monitors the scheduling information.

[0010] In one possible implementation, the first information further indicates a second SMTC window, where the second SMTC window is an SMTC window other than the first SMTC window in the at least one SMTC window. The method further includes measuring a synchronization signal block (SSB) in the second SMTC window. In this way, the terminal device can monitor scheduling information in the first SMTC window and measure the SSB in the second SMTC window based on the first information.

[0011] In one possible implementation, the first information indicates a pattern, where the pattern includes multiple bits, where bit i is used to indicate whether the SMTC window corresponding to bit i is used for monitoring scheduling information or for measuring SSB; bit i is any one of the multiple bits, and i is a positive integer greater than or equal to 1. In this way, the value of each bit in the pattern can indicate whether each SMTC window is an SMTC window for a terminal device to monitor scheduling information or an SMTC window for a terminal device to measure SSB.

[0012] In one possible implementation, the value of bit i is the second value, indicating that the SMTC window corresponding to bit i is used to monitor scheduling information; or the value of bit i is the third value, indicating that the SMTC window corresponding to bit i is used to measure SSB.

[0013] In one possible implementation, in response to the value of bit i being the third value, the first information further indicates a first panel, where the first panel is the panel used by the terminal device to measure the SSB within the SMTC window corresponding to bit i. In this way, within each second SMTC window, the terminal device uses the first panel to measure the SSB.

[0014] In one possible implementation, in response to the value of bit j being a third value, the first information further indicates a second panel, where the second panel is a panel used by the terminal device to measure SSB within the SMTC window corresponding to bit j. Bit j is one of multiple bits, j is a positive integer greater than or equal to 1, i and j are different, and the second panel is the same as or different from the first panel. In this way, within different second SMTC windows, the terminal device uses different panels to measure SSB, e.g., the first panel is used to measure SSB within the second SMTC window corresponding to bit i, and the second panel is used to measure SSB within the second SMTC window corresponding to bit j.

[0015] In one possible implementation, the method further includes: receiving second information from a network device, the second information indicating a third SMTC window and / or a fourth SMTC window; the third SMTC window is used to monitor scheduling information, the fourth SMTC window is used to measure SSB, and the reception time of the second information is later than the end time of at least one SMTC window. In this way, after the end of the at least one SMTC window, the terminal device can adjust its own behavior of measuring SSB / monitoring scheduling information according to the received second information. For example, the terminal device monitors scheduling information in the at least one SMTC window according to the first information. If the second information indicates the fourth SMTC window but does not indicate the third SMTC window, the terminal device measures SSB in the SMTC window after receiving the second information.

[0016] In one possible implementation, the method further includes: in response to receiving the first information, starting a timer, where the timer is pre-configured by the protocol or configured by the network device; in response to the timer expiring, measuring the SSB within a fifth SMTC window; and the start time of the fifth SMTC window is later than the timeout period of the timer. In this way, the terminal device can, based on the protocol pre-configuration or the configuration of the network device, perform corresponding actions according to the instructions of the first information if the timer has not timed out, and when the timer expires, fall back to a traditional mode in which all SMTC windows are used for SSB measurement, and measure the SSB within the fifth SMTC window.

[0017] In one possible implementation, before receiving the first information from the network device, the method further includes: sending third information to the network device; the third information indicates that the terminal device desires not to measure the SMTC window of the SSB. In this way, the terminal device pre-indicates to the network device that it desires not to measure the SMTC window of the SSB, so that the network device sends the first information according to the terminal device's instruction.

[0018] In a possible implementation manner, the first information is carried by radio resource control RRC signaling, or the first information is carried by media access control element MAC-CE signaling, or the first information is downlink indication information DCI.

[0019] In a second aspect, an embodiment of the present application provides another communication method, the method comprising:

[0020] A first message is sent to a terminal device; the first message indicates a first SMTC window in at least one synchronization signal block measurement timing configuration SMTC window; the start time of at least one SMTC window is later than the sending time of the first message; the first SMTC window is used for the terminal device to monitor scheduling information, and the scheduling information is used to schedule the transmission of uplink and downlink channels and / or signals.

[0021] In implementing the method described in the second aspect, the network device transmits the first information, causing the terminal device to not measure the SSB within a first SMTC window of at least one SMTC window, but instead to monitor the scheduling information of the network device. In this way, the network device can normally schedule the terminal device to transmit uplink and downlink channels and / or signals within the first SMTC window, thereby reducing scheduling constraints and improving system capacity.

[0022] In one possible implementation, the value of the first information is a first value, indicating that at least one SMTC window is used for the terminal device to monitor scheduling information. In this way, the network device can use the first information to instruct the terminal device not to measure the SSB in each SMTC window of the at least one SMTC window, but to monitor the scheduling information instead.

[0023] In one possible implementation, the first information further indicates a second SMTC window; the second SMTC window is used by the terminal device to measure the synchronization signal block (SSB), and the second SMTC window is an SMTC window other than the first SMTC window in the at least one SMTC window. In this way, the network device can instruct the terminal device, based on the first information, to monitor scheduling information within the first SMTC window and measure the SSB within the second SMTC window.

[0024] In one possible implementation, the first information indicates a pattern, where the pattern includes multiple bits, where bit i is used to indicate whether the SMTC window corresponding to bit i is used by the terminal device to monitor scheduling information or to measure the SSB. Bit i is any one of the multiple bits, and i is a positive integer greater than or equal to 1. In this way, the value of each bit in the pattern can indicate whether each SMTC window is an SMTC window used by the terminal device to monitor scheduling information or an SMTC window used by the terminal device to measure the SSB.

[0025] In one possible implementation, the value of bit i is the second value, indicating that the SMTC window corresponding to bit i is used for the terminal device to monitor scheduling information; or, the value of bit i is the third value, indicating that the SMTC window corresponding to bit i is used for the terminal device to measure SSB.

[0026] In one possible implementation, in response to the value of bit i being the third value, the first information further indicates a first panel, where the first panel is a panel used by the terminal device to measure the SSB within the SMTC window corresponding to bit i. In this way, the network device further instructs the terminal device to use the first panel to measure the SSB within each second SMTC window.

[0027] In one possible implementation, in response to the value of bit j being a third value, the first information further indicates a second panel, where the second panel is a panel used by the terminal device to measure SSB within the SMTC window corresponding to bit j; bit j is one of a plurality of bits, j is a positive integer greater than or equal to 1, i and j are different, and the second panel is the same as or different from the first panel. In this way, the network device instructs the terminal device to use different panels to measure SSB within different second SMTC windows.

[0028] In one possible implementation, the method further includes: sending second information to the terminal device, the second information indicating a third SMTC window and / or a fourth SMTC window; the third SMTC window is used for the terminal device to monitor scheduling information, and the fourth SMTC window is used for the terminal device to measure SSB, and the second information is sent later than the end time of at least one SMTC window. In this way, the network device can instruct the terminal device to adjust its SSB measurement / scheduling information monitoring behavior after the end of at least one SMTC window by sending the second information.

[0029] In one possible implementation, the first information further indicates a timer; the timer is used by the terminal device to measure the SSB within the fifth SMTC window in response to the timer expiration; the start time of the fifth SMTC window is later than the timer expiration time. In this way, the network device can instruct the terminal device to monitor scheduling information within the first SMTC window if the timer has not expired, and upon the timer expiration, fall back to the traditional mode in which all SMTC windows are used for SSB measurement and measure the SSB within the fifth SMTC window.

[0030] In one possible implementation, before sending the first information to the terminal device, the method further includes: receiving third information from the terminal device; the third information indicating that the terminal device desires not to measure the SMTC window for SSB. In this way, the network device may send the first information based on the instruction in the third information sent by the terminal device.

[0031] In a possible implementation manner, the first information is carried by radio resource control RRC signaling, or the first information is carried by media access control element MAC-CE signaling, or the first information is downlink indication information DCI.

According to the instruction of the network device, the terminal device does not measure the SSB within the SMTC window for monitoring scheduling information, but monitors the scheduling information sent by the network device.

[0059] First, some of the terms involved in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0060] 1. Extended Reality (XR)

[0061] In recent years, with the continuous development of the fifth-generation (5G) communication system, data transmission latency has been continuously reduced and transmission capacity has been increasing. 5G communication systems have gradually penetrated into some multimedia services with strong real-time requirements and large data capacity requirements, such as video transmission, cloud gaming (CG), and XR, among which XR includes virtual reality (VR) and augmented reality (AR).

[0062] With the rapid increase in communication transmission rates, real-time video transmission has gradually become one of the core services in current networks. The continuous advancement and improvement of extended reality technology has also led to the rapid development of related industries. Today, VR technology, as a type of XR, has entered various fields closely related to people's production and daily life, such as education, entertainment, military, medical care, environmental protection, transportation, and public health. Compared with traditional video services, VR offers advantages such as multiple perspectives and strong interactivity, providing users with a brand new visual experience.

[0063] In addition to smartphones, people are increasingly looking to enhance their XR experience through terminal devices such as head-mounted displays (HMDs) or smart glasses (such as VR glasses and AR glasses). Unlike smartphones, head-mounted displays and smart glasses require more consideration of power consumption. Smart glasses, in particular, are very small in size, similar to prescription glasses, and are expected to be worn for long periods of time, so power consumption control is significantly higher than that of smartphones. In cloud gaming, the UE can be a smartphone or a tablet. For long-term cloud gaming experiences, the power consumption of the device and the battery life are also important aspects to consider. Therefore, as XR devices become increasingly lightweight, the power consumption of the device has become a key issue in current research while ensuring user experience.

[0064] 2. Synchronization Signal Block (SSB)

[0065] The synchronization signal block consists of the primary synchronization signal (PSS), the secondary synchronization signal block (SSS), and the physical broadcast channel (PBCH) block, and is used for uplink synchronization and mobility management such as cell selection / handover.

[0066] 3. SSB transmission method

[0067] The network device periodically sends SSBs to the terminal device. Within one period, the multiple SSBs sent by the network device to the terminal device are called an SSB burst. For example, the period of sending the SSB burst can be 5ms, 10ms, 20ms, 40ms, 80ms, or 160ms. The network device can configure the period of the SSB burst based on the system information block (SIB). Generally, the total duration of an SSB burst is limited to one half frame (i.e., 5ms). The maximum number of SSBs in an SSB burst varies depending on the carrier frequency. For example, for the Sub3G frequency band, in the frequency division duplexing (FDD) mode and the time division duplexing (TDD) mode less than or equal to 2.4G, an SSB burst set includes a maximum of 4 SSBs, and in the TDD mode greater than 2.4G, an SSB burst set includes a maximum of 8 SSBs; for the Sub3G to Sub6G frequency bands, an SSB burst set includes a maximum of 8 SSBs; for the frequency band above 6G (FR2 band), an SSB burst set includes a maximum of 64 SSBs. Each SSB in the above SSB burst set can be indicated by an SSB Index, and the terminal device can obtain the SSB Index from the pilot of the PBCH or from the master system information block (MIB).

[0068] 4. Synchronous Signal Block Measurement Timing Configuration (SMTC) Window

[0069] The network device instructs the terminal device to measure the SSB time by configuring the SMTC window for the terminal device. Since SSB bursts are sent periodically and the total duration of an SSB burst is usually limited to 5ms, the protocol stipulates that the network device can configure the period of an SMTC window to be equal to the period of an SSB burst, and the window length (i.e., duration) of an SMTC window can be configured to be 1ms, 2ms, 3ms, 4ms, or 5ms. For example, the network device can configure the period of an SMTC window to be 5ms and the window length of an SMTC window to be 5ms.

[0070] After the network device configures the SMTC window for the terminal device, the terminal device will measure the SSB in the SMTC window. Therefore, the network device cannot send scheduling information to the terminal device within the SMTC window. There are scheduling limitations. For example, when the period of an SMTC window is configured to 20ms and the window length is configured to 5ms, if there are 64 SSBs to be measured in an SMTC window, the network device will be unable to schedule the terminal device nearly 20% of the time. This type of scheduling limitation will further reduce the system capacity of the communication system in specific business scenarios. Taking CG scenarios, AR scenarios, and VR scenarios as examples, Table 1 shows the loss of system capacity in these three scenarios under different SMTC window configurations. The system capacity in Table 1 is represented by the maximum number of UEs that can be served simultaneously by a network device.

[0071] Table 1

[0072] As shown in Table 1, in the absence of scheduling restrictions, the system capacity of the CG scenario is 9 UEs, and the system capacity of the AR / VR scenario is 7 UEs; when the SMTC window period is configured as 20ms and the window length is configured as 5ms, the system capacity of the CG scenario is 6.2 UEs (system capacity loss is 31%), and the system capacity of the AR / VR scenario is 3.1 UEs (system capacity loss is 56%); when the SMTC window period is configured as 20ms and the window length is configured as 3ms, the system capacity of the CG scenario is 8 UEs (system capacity loss is 11%), and the system capacity of the AR / VR scenario is 5.1 UEs (system capacity loss is 27%); when the SMTC window period is configured as 20ms and the window length is configured as When the length is configured as 2ms, the system capacity of the CG scenario is 8.5 UEs (system capacity loss is 6%), and the system capacity of the AR / VR scenario is 6.5 UEs (system capacity loss is 7%); when the SMTC window period is configured as 40ms and the window length is configured as 5ms, the system capacity of the CG scenario is 7.3 UEs (system capacity loss is 19%), and the system capacity of the AR / VR scenario is 4.1 UEs (system capacity loss is 41%); when the SMTC window period is configured as 40ms and the window length is configured as 2ms, the system capacity of the CG scenario is 8.6 UEs (system capacity loss is 4%), and the system capacity of the AR / VR scenario is 6.6 UEs (system capacity loss is 6%).

[0073] To reduce scheduling constraints and improve system capacity, an embodiment of the present application proposes a communication method. Based on this method, a network device can send an instruction to a terminal device to skip an SMTC window. That is, the network device instructs the terminal device not to measure SSBs within certain SMTC windows, but to monitor scheduling information instead. In this way, the network device can normally schedule the terminal device to transmit uplink and downlink channels and / or signals even within certain SMTC windows that the network device has instructed to skip, thereby reducing scheduling constraints and improving system capacity.

[0074] FIG2 shows a communication method provided by an embodiment of the present application, which includes but is not limited to the following steps:

[0075] Step 201: A network device sends first information to a terminal device, where the first information indicates a first SMTC window in at least one SMTC window. Accordingly, the terminal device receives the first information.

[0076] In an embodiment of the present application, a network device sends indication information to a terminal device to instruct the terminal device not to measure the SMTC window of the SSB (or skip measuring the SSB). The SMTC window in which the SSB is not measured can be used to transmit scheduling information. The network device may send such indication information multiple times. Assume that the indication information sent by the network device at a certain time is called the first information, and there is at least one SMTC window in the time period from sending the first information to sending the next new indication information.

[0077] The first information indicates a first SMTC window among the at least one SMTC windows, and the first SMTC window is used for the terminal device to monitor scheduling information without measuring the SSB. The start time of the at least one SMTC window is later than the time when the network device sends the first information, and the start time of the at least one SMTC window is later than the time when the terminal device receives the first information. In other words, the network device can instruct the terminal device through the first information to monitor scheduling information instead of measuring the SSB in the first SMTC window among the at least one subsequent SMTC windows.

[0078] Optionally, in the first case, each of the at least one SMTC window is the first SMTC window, which is equivalent to the network device instructing the terminal device through the first information that SSB should not be measured in the next at least one SMTC window but scheduling information should be monitored until the network device sends new indication information to the terminal device.

[0079] Optionally, in the second case, a portion of the at least one SMTC window (when the number is two or more) is the first SMTC window, and another portion of the SMTC window is not the first SMTC window. For example, when the first information indicates the first SMTC window, it also indicates the second SMTC window, and the second SMTC window is the SMTC window other than the first SMTC window in the at least one SMTC window. The second SMTC window is used for the terminal device to measure the SSB. This is equivalent to the network device instructing the terminal device through the first information to listen to the scheduling information in the first SMTC window in the next at least one SMTC window and measure the SSB in the second SMTC window until the network device sends new indication information to the terminal device.

[0080] Furthermore, optionally, the first information also indicates a panel corresponding to the second SMTC window, and the number of panels may be one or more, so that the terminal device can use the panel corresponding to the second SMTC window to measure the SSB within the second SMTC window. For example, when the number of panels indicated by the first information is one, the panel indicated by the first information is used for all second SMTC windows, so that the terminal device does not need to change the panel used when measuring the SSB; or, the first information may indicate the panel corresponding to each second SMTC window respectively, and the panels corresponding to each second SMTC window may be the same or different, and the panel corresponding to each second SMTC window is used for the corresponding second SMTC window. In this way, the terminal device can change the currently used panel when measuring the SSB, such as switching to a panel with a better signal, to improve communication quality.

[0081] Optionally, the network device may pre-receive capability information reported by the terminal device, where the capability information indicates the capability of each panel in the terminal device, and then the network device selects a panel with better capability as the panel corresponding to the second SMTC window based on the capability information.

[0082] Optionally, the first information further indicates a panel corresponding to the first SMTC window, and the number of panels may be one or more, so that the terminal device can use the panel corresponding to the first SMTC window to monitor scheduling information within the first SMTC window. For example, the network device may indicate one panel for all first SMTC windows in the first information, or indicate a corresponding panel for each first SMTC window.

[0083] Optionally, the first information also indicates a timer, and the timer is used for the terminal device to measure SSB in the fifth SMTC window in response to the timer timing out. The start time of the fifth SMTC window is later than the timeout time of the timer. In this way, the terminal device can start the timer first when receiving the first information, and perform corresponding actions according to the instructions of the above-mentioned first information before the timer times out; after the timer times out, the terminal device responds to the timer timeout and falls back to the traditional mode for measuring SSB in the SMTC window, and measures SSB in the time slot configured with SSB in the SMTC window after the timeout (i.e., the fifth SMTC window), until the network device sends new indication information to the terminal device, then the terminal device can restart the timer to start a new round of timing.

[0084] For example, if the timeout period of the timer is less than the end time of at least one SMTC window, it means that after the timer times out, there are still remaining SMTC windows in the at least one SMTC window, and the remaining SMTC window is the fifth SMTC window.

[0085] For example, if the timer timeout period is greater than or equal to the end time of at least one SMTC window, it means that before the end of at least one SMTC window (that is, before the network device sends new indication information), the timer will not time out, so the fifth SMTC window does not exist. Accordingly, the terminal device performs corresponding actions within at least one SMTC window according to the instructions of the above-mentioned first information.

[0086] In one possible implementation, the first information is carried by radio resource control (RRC) signaling, or by media access control element (MAC-CE) signaling, or is downlink indication information (DCI), etc. It is understandable that the first information may also be carried in other ways, which are not limited in this application.

[0087] In one possible implementation, the above-mentioned scheduling information is used to schedule the transmission of uplink and downlink channels and / or signals. The network device may send scheduling information (such as DCI information) to the terminal device within the above-mentioned first SMTC window to schedule the terminal device, so that the terminal device transmits uplink and downlink channels and / or signals in response to the scheduling information.

[0088] For example, downlink channels and / or signals include, but are not limited to, physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH) and / or channel state information reference signal (CSI-RS), etc. Uplink channels and / or signals include, but are not limited to, physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH) and / or sounding reference signal (SRS), etc.

[0089] Optionally, as shown in FIG3 , step 200 is further included before step 201: In step 200, the terminal device sends third information to the network device, the third information indicating that the terminal device desires not to measure the SMTC window of the SSB; accordingly, the network device receives the third information. In this way, the network device can select a first SMTC window from the SMTC windows indicated by the terminal device as not to measure the SSB, or the network device can select an SMTC window other than the SMTC window indicated by the third information as the first SMTC window, which is not limited in this application.

[0090] In one possible implementation, the third information is carried by RRC signaling, or by MAC-CE signaling, or the first information is uplink indication information (UCI), etc. It is understood that the third information may also be carried in other ways, which are not limited in this application. Specifically, the form of the third information may refer to the form of the indication information described below.

[0091] Step 202: The terminal device monitors scheduling information in the first SMTC window.

[0092] After receiving the first information, the terminal device may monitor scheduling information in the first SMTC window indicated by the first information. If the terminal device monitors scheduling information (such as DCI information) sent by the network device within the first SMTC window, it may transmit uplink and downlink channels and / or signals in response to the scheduling information. This increases the network device's opportunity to schedule the terminal device, thereby reducing scheduling constraints and improving system capacity.

[0093] Optionally, in the first case above, each of the at least one SMTC window is a first SMTC window, and the terminal device listens to the scheduling information in each of the at least one SMTC window according to the instruction of the first information, and does not measure the SSB.

[0094] Optionally, in the second case above, when the at least one SMTC window (when the number is two or more) includes a first SMTC window and a second SMTC window, the terminal device listens to the scheduling information in the first SMTC window and does not measure the SSB according to the instructions of the first information, and measures the SSB in the second SMTC window.

[0095] Further, optionally, when the first information also indicates a panel corresponding to the second SMTC window, the terminal device uses the panel corresponding to the second SMTC window to measure the SSB in the second SMTC window.

[0096] Further, optionally, when the first information further indicates a panel corresponding to the first SMTC window, the terminal device uses the panel corresponding to the first SMTC window to monitor the scheduling information in the first SMTC window.

[0097] Optionally, the terminal device may also start a timer in response to receiving the first information, where the timer is pre-configured by the protocol or configured by the network device (such as configuring the timer through the above-mentioned first information). When the timer has not timed out, the terminal device performs corresponding actions according to the instructions of the first information; after the timer times out, if at least one SMTC window has not ended (that is, no new indication information has been received), the terminal device measures the SSB in the remaining SMTC windows in the at least one SMTC window (that is, the above-mentioned fifth SMTC window). If at least one SMTC window ends before the timer, when the terminal device ends at at least one SMTC window (that is, when new indication information is received), the terminal device restarts the timer to start a new round of timing, and monitors the scheduling information and / or measures the SSB according to the new indication information in the new round of timing.

[0098] For example, assuming that at least one SMTC window includes four SMTC windows (SMTC window 1, SMTC window 2, SMTC window 3, and SMTC window 4), as shown in FIG4 , if the first information indicates that the four SMTC windows are all used for the terminal device to monitor scheduling information (equivalent to each of the four SMTC windows being the first SMTC window), and SMTC window 4 is not detected when the timer times out, then SMTC window 4 is equivalent to the fifth SMTC window, and the terminal device monitors scheduling information in SMTC window 1, SMTC window 2, and SMTC window 3, and measures SSB in SMTC window 4; or, As shown in Figure 5, if the first information indicates that one is measured and jumped among the four SMTC windows, measuring and jumping means that the SMTC window with an odd sequence number is used for the terminal device to measure SSB (equivalent to SMTC window 1 and SMTC window 3 being the second SMTC window), and the SMTC window with an even sequence number is used for the terminal device to monitor scheduling information (equivalent to SMTC window 2 and SMTC window 4 being the first SMTC window), and the terminal device has not detected SMTC window 4 when the timer times out, then the terminal device measures SSB in SMTC window 1, SMTC window 3 and SMTC window 4, and monitors scheduling information in SMTC window 2.

[0099] Based on the embodiment described in FIG2 , the network device sends first information to the terminal device. Based on the first information, the terminal device does not measure the SSB within a first SMTC window of at least one SMTC window, but instead monitors scheduling information from the network device. This allows the network device to normally schedule the terminal device for uplink and downlink channel and / or signal transmission within the first SMTC window, thereby reducing scheduling constraints and improving system capacity.

[0100] Optionally, after step 202 in the above embodiment, the network device may also send second information to the terminal device, where the second information indicates a third SMTC window and / or a fourth SMTC window, the third SMTC window is used for the terminal device to monitor scheduling information, and the fourth SMTC window is used for the terminal device to measure SSB, and the sending time of the second information is later than the end time of at least one SMTC window.

[0101] The second information can be understood as new instruction information sent by the network device to the terminal device after sending the first information. The at least one SMTC window can be understood as the SMTC window in the time period from when the network device sends the first information to when it sends the second information.

[0102] Specifically, the second information indicates that the third SMTC window does not indicate the fourth SMTC window, indicating that in the time period from sending the second information to sending the next new indication information, the network device instructs the terminal device to listen to the scheduling information in each SMTC window, similar to the first case in the above step 201.

[0103] Alternatively, the second information indicates that the fourth SMTC window does not indicate the third SMTC window, indicating that during the time period from sending the second information to the next sending of new indication information, the network device instructs the terminal device to measure SSB in each SMTC window. If the first information indicates only the first SMTC window and does not indicate the second SMTC window, when the network device sends the second information to the terminal device, the terminal device may adjust its behavior from never measuring any SMTC window to measuring any SMTC window.

[0104] Alternatively, the second information may indicate the third SMTC window and the fourth SMTC window, indicating that in the time period from sending the second information to the next sending of new indication information, the network device instructs the terminal device to listen to the scheduling information in the third SMTC window and measure the SSB in each fourth SMTC window.

[0105] It can be seen that the network device can instruct the terminal device to adjust its own behavior of measuring SSB / monitoring scheduling information after at least one SMTC window ends by sending the second information.

[0106] The following first gives an example of possible forms of the indication information sent by the network device to the terminal device, and then describes in detail the indication information as the first information.

[0107] Form 1: The indication information indicates a status value, which indicates whether the SMTC window is used by the terminal device to monitor scheduling information or to measure SSB. This status value is applicable to each SMTC window.

[0108] For example, the indication information is carried by RRC signaling, and the RRC signaling may be RRC reconfiguration signaling (RRC Reconfiguration signaling). The information element (IE) may be extended in advance in the RRC signaling. The type of the extended IE may be an enumeration type or a Boolean type, and the value of the extended IE is a status value. In one example, the extended IE is an enumeration type, and the values ​​of the extended IE are "1" and "2", where "1" indicates that the SMTC window is used for the terminal device to monitor scheduling information, and "2" indicates that the SMTC window is used for the terminal device to measure SSB. In another example, the extended IE is a Boolean type, and the values ​​of the extended IE are "True" or "False", or the values ​​of the extended IE are "Enable" or "Disable", where "True" and "Enable" indicate that the SMTC window is used for the terminal device to monitor scheduling information, and False and Disable indicate that the SMTC window is used for the terminal device to measure SSB.

[0109] For example, the indication information is carried by MAC-CE signaling, and a new field can be added to the MAC-CE signaling in advance. The value of the new field is a status value. For example, as shown in Figure 6, an N field is added after the R field in the MAC-CE signaling, and the value of the N field is "0" or "1". Among them, the value of the N field is "0" to indicate that the SMTC window is used for the terminal device to measure the SSB, and the value of the N field is "1" to indicate that the SMTC window is used for the terminal device to monitor the scheduling information.

[0110] For example, the indication information is carried by DCI information, and one bit may be pre-extended in the DCI information. The value of this bit is a status value. For example, the value of this bit may be "0" or "1." A value of "0" indicates that the SMTC window is used for the terminal device to measure the SSB, and a value of "1" indicates that the SMTC window is used for the terminal device to monitor scheduling information.

[0111] Optionally, in the following form, if the indication information also needs to indicate a timer or panel, the timer information or panel information can be carried by extending the IE in the RRC signaling, adding a new field in the MAC-CE signaling, or adding a new bit in the DCI information. The specific extension method is not limited.

[0112] Furthermore, optionally, if the indication information indicates that the SMTC window is used for the terminal device to monitor scheduling information, the indication information may no longer indicate the panel; if the indication information indicates that the SMTC window is used for the terminal device to measure SSB, the indication information may also indicate the panel used when measuring SSB.

[0113] It should be noted that after the terminal device receives the indication information in form one, it can measure the SSB or monitor the scheduling information in each SMTC window until it receives new indication information.

[0114] As shown in FIG7 , if the value of the indication information received by the terminal device this time is “True”, and the pattern indicated by the indication information received by the terminal device next time is “False”.

[0115] If there are multiple SMTC windows (including SMTC window 1, SMTC window 2, SMTC window 3, SMTC window 4, etc.) in the interval between the two indication messages, "True" applies to each of these multiple SMTC windows. Therefore, the terminal device monitors the scheduling information in SMTC window 1, SMTC window 2, SMTC window 3, SMTC window 4, etc.

[0116] Form 2: The indication information indicates a pattern, which indicates whether multiple SMTC windows are all used for the terminal device to monitor scheduling information, all used for the terminal device to measure SSB, or part of them is used to monitor scheduling information and the other part is used to measure SSB.

[0117] In one possible implementation, the pattern may include multiple bits, where the number of the multiple bits is a positive integer greater than 1. Assume that bit i is any bit among the multiple bits, and i is a positive integer greater than or equal to 1. Bit i is used to indicate that the SMTC window corresponding to bit i is used for the terminal device to monitor scheduling information, or that the SMTC window corresponding to bit i is used for the terminal device to measure the SSB.

[0118] Taking a pattern consisting of 4 bits as an example, the pattern can take multiple values ​​such as "1010", "1011", "1111" or "0000". Among them. Assume that the value of bit i in the pattern is "1", indicating that the SMTC window corresponding to bit i is used for the terminal device to measure SSB, and the value is "0", indicating that the SMTC window corresponding to bit i is used for the terminal device to monitor scheduling information. Then when the value of the pattern is "1010", it means that every four SMTC windows are regarded as a group. In a group of SMTC windows, one SMTC window is skipped when measuring one SMTC window, and the skipped SMTC window is used to monitor scheduling information. When the value of the pattern is "1011", it means that every four SMTC windows are regarded as a group. In a group of SMTC windows, the first SMTC window, the third SMTC window and the fourth SMTC window are all used to measure SSB, and the second SMTC window is used to monitor scheduling information. When the value of the pattern is "1111", it means that every four SMTC windows are regarded as a group. In a group of SMTC windows, each SMTC window is used to measure SSB. When the value of the pattern is "0000", it indicates that every four SMTC windows are regarded as a group, and in a group of SMTC windows, each SMTC window is used to monitor scheduling information.

[0119] Furthermore, optionally, an identifier corresponding to the pattern may be pre-set, and the indication information may indicate the corresponding pattern to the terminal device by carrying the identifier corresponding to the pattern. Accordingly, the terminal device may determine the value of the pattern based on the identifier corresponding to the pattern.

[0120] For example, multiple patterns may be notified to the terminal device in advance through RRC reconfiguration signaling, for example, in the following manner:

[0121] smtcMeasPatternList{{measPattern},…,}

[0122] smtcMeasPatternList{

[0123] {1010},

[0124] {1011},

[0125] {1111},

[0126] {0000},

[0127] …

[0128] }

[0129] smtcMeasPatternList represents a list of patterns notified to the terminal device, and measpattern represents one of the patterns. For example, smtcMeasPatternList includes "1010," "1011," "1111," and "0000." For example, the index of each pattern can be obtained based on the order of each pattern in smtcMeasPatternList. For example, an index value of "1" corresponds to a pattern value of "1010," an index value of "2" corresponds to a pattern value of "1011," an index value of "3" corresponds to a pattern value of "1111," an index value of "4" corresponds to a pattern value of "0000," and so on. When the value of the indication information is "1," the indicated pattern is "1010," meaning that every four SMTC windows are considered a group. Within a group of SMTC windows, one SMTC window is skipped for each measurement. The skipped SMTC window is used to monitor scheduling information.

[0130] In another possible implementation, the pattern may include multiple bits, the number of the multiple bits is a positive integer greater than 1, and the multiple bits include a first-level indication bit (such as K) and a second-level indication bit (P), the first-level indication bit indicates that the SMTC window is the first SMTC window and / or the second SMTC window, and the second-level indication bit indicates the number of first SMTC windows and / or the number of second SMTC windows. In one example, the indication information may be in the form of "K1 P1 K2 P2 K3 P3...", and in another example, the indication information may be in the form of "K1 K2 K3 P1 P2 P3...". The difference between these two forms is that the types of all SMTC windows (i.e., whether the SMTC window is the second SMTC window for measuring SSB or the first SMTC window for monitoring scheduling information) can be uniformly indicated in sequence first and then the number of different types of SMTC windows can be indicated, or different types of SMTC windows and the corresponding numbers can be indicated separately. Optionally, the number of bits occupied by K and P can be preset. For example, K is one bit, and its value is "0" or "1", indicating that the SMTC window is the first SMTC window or the second SMTC window, respectively. P is two bits, and its value is any value from "01" to "11", indicating that the number of SMTC windows is any value from 1 to 3. For example, the value of the indication information may be "1 11 0 10 1 01" or "1 0 1 11 10 01", where the first bit in "1 11 0 10 1 01" indicates that the SMTC window is the second SMTC window, the second bit and the third bit indicate that the number of second SMTC windows corresponding to the first bit is 3, the fourth bit indicates that the SMTC window is the first SMTC window, the fifth bit and the sixth bit indicate that the number of first SMTC windows corresponding to the fourth bit is 2, the seventh bit indicates that the SMTC window is the second SMTC window, and the eighth bit and the ninth bit indicate that the number of second SMTC windows corresponding to the seventh bit is 1; the first three bits in "1 0 1 11 10 01" indicate that at least one SMTC window includes the second SMTC window, the first SMTC window, and the second SMTC window, in sequence, and the last six bits indicate that the corresponding numbers of these types of SMTC windows are 3, 2, and 1, respectively. Both values ​​enable the terminal device to first measure SSB within 3 SMTC windows, then not measure SSB within the next 2 SMTC windows but monitor scheduling information, and then continue to measure SSB within the next 1 SMTC.

[0131] Furthermore, for the second-level indicator bit (P), when the value of P is 0 (e.g., when it occupies two bits, both bits are "00"), it is equivalent to indicating that the number of first / second SMTC windows is 0. Since when the number of first SMTC windows is 0, the SMTC window is equivalent to the second SMTC window, which can be indicated by K taking a value of "1", and when the number of second SMTC windows is 0, the SMTC window is equivalent to the first SMTC window, which can be indicated by K taking a value of "0", a P value of 0 is a repeated indication. To maximize the use of the indicator bits, the value of P can indicate the corresponding number of SMTC windows as P+1. For example, when P occupies two bits, setting P to "00" indicates that the number of SMTC windows is 1, "01" indicates that the number of SMTC windows is 2, "10" indicates that the number of SMTC windows is 3, and P to "11" indicates that the number of SMTC windows is 4. In this way, when it is necessary to indicate that the number of SMTC windows is 4, it is not necessary to use three bits (such as "100") for indication, but it can be indicated by two bits, thereby further reducing bit overhead and improving bit utilization.

[0132] For example, the indication information in the above-mentioned form 2 is carried by RRC signaling, MAC-CE signaling, or DCI information. For example, the amount of data transmitted by RRC signaling is generally greater than that of MAC-CE signaling and DCI information. In this case, the pattern can be indicated by RRC signaling, or the identifier (pattern index) corresponding to the pattern can be indicated by MAC-CE signaling or DCI information. The indication method can be implemented by extending IE, adding a new field, or adding a new bit.

[0133] Optionally, in the above second form, if the indication information also needs to indicate a timer, the timer information can be directly carried, or the timer can be indicated by carrying an index.

[0134] For example, an IE may be further extended in RRC signaling to carry timer information. Alternatively, a bit may be extended in MAC-CE signaling or DCI information to carry a pattern index. The pattern index not only indicates the pattern value, but also indicates the timer information corresponding to the pattern. Accordingly, the terminal device may determine the pattern value and timer information based on the pattern index.

[0135] For example, multiple patterns and timer information corresponding to each pattern are notified to the terminal device in advance through RRC reconfiguration signaling, for example, the notification can be made in the following manner:

[0136] smtcMeasPatternList{{measPattern, timer},…,}

[0137] smtcMeasPatternList{

[0138] {1010, timer1},

[0139] {1011, timer2},

[0140] {1111, timer3},

[0141] {0000, timer4},

[0142] …

[0143] }

[0144] Where measpattern represents a pattern, and timer represents timer information. For example, smtcMeasPatternList includes "1010," "1011," "1111," and "0000." The timer information corresponding to "1010" is "timer1," "1011" is "timer2," "1111" is "timer3," "0000" is "timer4," and so on. The index of each pattern and timer can be obtained based on the order of each pattern in smtcMeasPatternList. For example, an index value of "1" corresponds to a pattern value of "1010" and timer information of "timer1," an index value of "2" corresponds to a pattern value of "1011" and timer information of "timer2," an index value of "3" corresponds to a pattern value of "1111" and timer information of "timer3," an index value of "4" corresponds to a pattern value of "0000" and timer information of "timer4," and so on. If the value of the newly added field in the MAC-CE signaling is 1, it indicates that the pattern indicated by the newly added field is "1010" and the timer information is "timer1." Optionally, the timers for different patterns can be the same or different.

[0145] Optionally, in form 2, if the indication information also needs to indicate a panel, the network device may indicate a panel for all first SMTC windows / second SMTC windows in the pattern, or indicate a corresponding panel for each first SMTC window / each second SMTC window in the pattern.

[0146] Taking the second SMTC window indication panel as an example, in one possible implementation, in response to the value of bit i being the third value, the indication information also indicates the first panel, which is the panel used by the terminal device to measure SSB within the SMTC window corresponding to bit i.

[0147] For example, the terminal device is equipped with three panels, namely panel-A, panel-B and panel-C. If the value of the indication information is "1010 01", the first four bits in "1010 01" represent the pattern, and the last two bits represent panel-A. According to "1010 01", the terminal device regards every four SMTC windows as a group. In a group of SMTC windows, one SMTC window is skipped when measuring one SMTC window. The skipped SMTC window is used for the terminal device to monitor scheduling information, and the non-skipped SMTC window is used for the terminal device to measure SSB using panel-A.

[0148] In another possible implementation, the indication information indicates the first panel and, in response to the value of bit j being a third value, indicates the second panel, where the second panel is the panel used by the terminal device to measure SSB within the SMTC window corresponding to bit j.

[0149] Wherein, bit j is a bit among multiple bits, j is a positive integer greater than or equal to 1, i and j are different, and the second panel is the same as or different from the first panel. For example, the value of the indication information is "1010 01 10", the first four bits of "1010 01 10" represent the pattern, the fifth and sixth bits represent panel-A, and the last two bits represent panel-B. Based on "1010 01 10", the terminal device regards every four SMTC windows as a group, uses panel-A to measure SSB in the first SMTC window of the group, uses panel-B to measure SSB in the third SMTC window of the group, and does not measure SSB in the second and fourth SMTC windows of the group, but instead monitors scheduling information.

[0150] It should be noted that after the terminal device receives the indication information of form 2, it can monitor the scheduling information or measure the SSB in the SMTC window corresponding to any bit in the pattern according to the methods shown in Figures 8 to 11:

[0151] Assume that, corresponding to the first possible implementation method introduced in the above form 2, if the pattern indicated by the indication information received by the terminal device this time is "1010", and the pattern indicated by the indication information received by the terminal device next time is "1011".

[0152] As shown in Figure 8, if there are four SMTC windows (SMTC Window 1, SMTC Window 2, SMTC Window 3, and SMTC Window 4) in the interval between receiving the two indication messages, SMTC Window 1 corresponds to the first bit "1" in "1010," SMTC Window 2 corresponds to the second bit "0" in "1010," SMTC Window 3 corresponds to the third bit "1" in "1010," and SMTC Window 4 corresponds to the fourth bit "0" in "1010." Therefore, the terminal device measures the SSB in SMTC Window 1, monitors scheduling information in SMTC Window 2, measures the SSB in SMTC Window 3, and monitors scheduling information in SMTC Window 4.

[0153] As shown in Figure 9, if three SMTC windows (SMTC window 1, SMTC window 2, and SMTC window 3) exist in the interval between receiving the two indication messages, SMTC window 1 corresponds to the first bit "1" in "1010," SMTC window 2 corresponds to the second bit "0" in "1010," and SMTC window 3 corresponds to the third bit "1" in "1010." Therefore, the terminal device measures the SSB in SMTC window 1, monitors scheduling information in SMTC window 2, and measures the SSB in SMTC window 3.

[0154] As shown in Figure 10, if six SMTC windows (SMTC window 1, SMTC window 2, SMTC window 3, SMTC window 4, SMTC window 5, and SMTC window 6) exist in the interval between receiving the two indication messages, then SMTC window 1 corresponds to the first bit "1" in "1010," SMTC window 2 corresponds to the second bit "0" in "1010," SMTC window 3 corresponds to the third bit "1" in "1010," SMTC window 4 corresponds to the fourth bit "0" in "1010," SMTC window 5 corresponds to the first bit "1" in "1010," and SMTC window 6 corresponds to the second bit "0" in "1010." Therefore, the terminal device measures the SSB in SMTC window 1, monitors scheduling information in SMTC window 2, measures the SSB in SMTC window 3, monitors scheduling information in SMTC window 4, measures the SSB in SMTC window 5, and monitors scheduling information in SMTC window 6.

[0155] Assume that, corresponding to the first possible implementation method introduced in the above form 2, if the pattern indicated by the indication information received by the terminal device this time is "1 11 0 10 1 01", and the pattern indicated by the indication information received by the terminal device next time is "1 101 10 0 01", then it means that there are six SMTC windows (including SMTC window 1, SMTC window 2, SMTC window 3, SMTC window 4, SMTC window 5 and SMTC window 6) shown in Figure 11 in the interval time period between the reception of these two indication information, wherein the first three bits "1 10" in "1 11 0 10 1 01" correspond to SMTC window 1, SMTC window 2 and SMTC window 3, the middle three bits "0 10" correspond to SMTC window 4 and SMTC window 5, and the last three bits "1 01" corresponds to SMTC window 6, the terminal device measures SSB in SMTC window 1, SMTC window 2 and SMTC window 3, monitors scheduling information in SMTC window 4 and SMTC window 5, and measures SSB in SMTC window 6.

[0156] It should be noted that the meanings of the various values ​​in the above two forms are only examples and are not limited in this application.

[0157] In combination with the possible forms of the above-mentioned indication information, the possible forms of the first information in the embodiment of FIG2 are illustrated as follows:

[0158] Case 1: Each SMTC window in the at least one SMTC window is a first SMTC window.

[0159] The form of the first information in the first case may be the above-mentioned form 1 or form 2.

[0160] If the first information is in the aforementioned form 1, the value of the first information may be a first value, indicating that the at least one SMTC window is used for the terminal device to monitor scheduling information. When the at least one SMTC window is used for the terminal device to monitor scheduling information, each of the at least one SMTC window is equivalent to a first SMTC window.

[0161] For example, the first information may be carried in RRC Reconfiguration signaling, and the value of the first information (first value) may be the value of the extended IE in the above corresponding example. When the value is "1" in the enumeration type, or the value is "True" in the Boolean type, or the value is "Enable" in the Boolean type, the first information indicates that the at least one SMTC window is an SMTC window for monitoring scheduling information. For example, the first information may be carried in the N field of MAC-CE signaling, and the value of the first information (first value) may be the value of the N field in the above corresponding example. When the value of the N field is "1", the first information indicates that the at least one SMTC window is an SMTC window for monitoring scheduling information. For example, the first information may be carried in DCI information, and the value of the first information (first value) may be the value of an extended bit in the DCI information in the above corresponding example. When the value of this bit is "1", the first information indicates that the at least one SMTC window is an SMTC window for monitoring scheduling information.

[0162] If the form of the first information is the above-mentioned form 2, then in one example, the first information indicates a pattern, the pattern includes multiple bits, and the value of each bit is the second value, indicating that the SMTC window corresponding to each bit is used for the terminal device to monitor scheduling information. When the SMTC window corresponding to each bit is used for the terminal device to monitor scheduling information, each SMTC window in at least one SMTC window is a first SMTC window. For example, the first information can be carried in the RRC Reconfiguration signaling, and the value of the first information (first value) can be the value of the pattern in the above-mentioned corresponding example, corresponding to the pattern including 4 bits in the above-mentioned example, when the value is "0000", the first information indicates that every 4 SMTC windows are a group, and each SMTC window in each group is an SMTC window for monitoring scheduling information. For example, the first information may be carried in MAC-CE signaling or the first information may be carried in DCI information, and the value of the first information (first value) may be the value of the identifier corresponding to the pattern in the above corresponding example, corresponding to the several possible values ​​of the identifier corresponding to the pattern shown in the above example, when the value is "4", corresponding to the pattern "0000", the first information may still indicate that every 4 SMTC windows are a group, and each SMTC window in each group is an SMTC window for monitoring scheduling information. In another example, the first information indicates a pattern, and the pattern includes multiple bits, and the multiple bits include a first-level indication bit and a second-level indication bit. When the value of the first-level indication bit indicates that the corresponding SMTC window is the first SMTC window for the terminal device to monitor scheduling information, and the second-level indication bit indicates that the number of first SMTC windows is equal to the number of at least one SMTC window, each SMTC window in the at least one SMTC window is a first SMTC window. For example, the first information may be carried in the RRC Reconfiguration signaling. If the number of at least one SMTC window is 3, the value of the first information may be "0 11", and the first information indicates that the next three SMTC windows are all used for the terminal device to monitor scheduling information.

[0163] Optionally, in this case, the first information may further indicate a timer. For example, the first information may be "True", "timer1", or the first information may be "0000", "timer1", or the first information may be "0 11", "timer1".

[0164] The second case: at least one SMTC window (when the number is two or more) includes a first SMTC window and a second SMTC window.

[0165] The format of the first information in the second case may be the aforementioned format 2 (format 1 cannot indicate both the first SMTC window and the second SMTC window at the same time).

[0166] In one example, the first information indicates a pattern, where the pattern includes multiple bits. Some of the multiple bits have a second value, indicating that the corresponding SMTC window is used for a terminal device to monitor scheduling information, and other bits have a third value, indicating that the corresponding SMTC window is used for the terminal device to measure SSB. Thus, the SMTC window corresponding to the second value is the first SMTC window, and the SMTC window corresponding to the third value is the second SMTC window.

[0167] For example, the second value may be "0", the third value may be "1", the first information may be carried in RRC Reconfiguration signaling, and the value of the first information may be "1010". For another example, if the first information is carried in MAC-CE signaling or the first information is carried in DCI information, the value of the first information may be index "1" corresponding to "1010".

[0168] Furthermore, in another example, the first information indicates a pattern, the pattern including multiple bits, the multiple bits including a first-level indicator bit and a second-level indicator bit, the first-level indicator bit indicating a first SMTC window and a second SMTC window, the second-level bit indicating the number of the first SMTC window and the second SMTC window, and the number of at least one SMTC window equals the sum of the numbers of the SMTC windows indicated by the second-level indicator bits. For example, if the pattern takes the form of "K1 P1 K2 P2 K3 P3", and the value is "1 11 0 10 1 01", then K1 = 1, K2 = 0, K3 = 1, P1 = 11, P2 = 10, and P3 = 01, so the sum of P is 3 + 2 + 1 = 6, indicating that, within the next six SMTC windows, the first SMTC window to the third SMTC window and the sixth SMTC window are the second SMTC windows, and the fourth SMTC window and the fifth SMTC window are the first SMTC window.

[0169] Optionally, in this case, the first information may further indicate a timer. The specific method for indicating the timer may refer to the description in the above-mentioned form 2. For example, the first information may be "1010", "timer1", or "1 11 0 10 1 01", "timer1".

[0170] Optionally, in this case, the first information may also indicate a panel, and the specific method of indicating the panel may refer to the description in the above-mentioned form 2. For example, the first information may be "1010 01 10", where "1010" is the four bits corresponding to the pattern, "01 10" is the index of the panel, "01" in "01 10" is the index of panel-A, which is used to indicate the panel corresponding to the first SMTC window in a group of SMTC windows indicated by the pattern, and "10" in "0110" is the index of panel-B, which is used to indicate the panel corresponding to the third SMTC window in a group of SMTC windows indicated by the pattern.

[0171] Based on the indication of the first information in the above two situations, the terminal device may not measure the SSB in the first SMTC window in at least one SMTC window, but monitor the scheduling information. After monitoring the scheduling information, the terminal device may transmit uplink and downlink channels and / or signals with the network device, thereby reducing scheduling restrictions and improving system capacity.

[0172] The following introduces the software structure of the above network equipment and terminal equipment.

[0173] As shown in Figure 12, Figure 12 is a schematic diagram of the hardware structure of a communication device provided in an embodiment of the present application, wherein the communication device 1200 shown in Figure 12 may include a sending unit 1201 and a receiving unit 1202.

[0184] In one possible implementation, before the receiving unit 1202 receives the first information from the network device, the sending unit 1201 is configured to send third information to the network device; the third information indicates that the terminal device expects not to measure the SMTC window of the SSB.

[0185] In a possible implementation manner, the first information is carried by radio resource control RRC signaling, or the first information is carried by media access control element MAC-CE signaling, or the first information is downlink indication information DCI.

[0198] It should be noted that the specific implementation and beneficial effects of the operations performed by the communication device 1200 can be found in the corresponding description in the above method embodiment, which will not be repeated here.

[0199] The hardware structure of the above network equipment and terminal equipment is introduced below.

[0200] As shown in FIG13 , FIG13 is a schematic diagram of the hardware structure of a communication device provided in an embodiment of the present application. The communication device 1300 may be a terminal device or a network device in the above content.

[0201] For example, the communication device 1300 includes one or more processors 110, one or more memories 120, and one or more communication interfaces 130.
