Optionally, the wireless communication system 100 may also include other network entities such as a network controller and a mobility management entity, which is not limited in the embodiment of the present application.

The terminal device in the embodiment of the present application may be a device that provides voice and / or data connectivity to a user, and can be used to connect people, objects and machines, such as a handheld device with wireless connection function, a vehicle-mounted device, etc. The terminal device in the embodiment of the present application can be a mobile phone, a tablet computer, a laptop, a PDA, a mobile internet device (MID), a wearable device, a virtual reality (VR) device, an augmented reality (AR) device, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical surgery, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. Optionally, the terminal device can be used to act as a base station. For example, the terminal device can act as a scheduling entity, which provides sidelink signals between terminal devices in vehicle to everything (V2X) or device to device (D2D). For example, a cellular phone and a car communicate with each other using a sidelink signal. Cellular phones and smart home devices communicate without relaying communication signals through a base station.
[0031] The network device in the embodiment of the present application may be a device for communicating with a terminal device. The network device may be, for example, an access network device or a wireless access network device. For example, the network device may be a base station.

[0032] Rate Matching
[0033] In wireless communication systems, rate matching is a process used to adjust the data rate to match the transmission capacity of the physical layer. During the rate matching process, a series of processes need to be performed on the transport block (TB), and its length is adjusted to adapt to the transmission capacity of the channel through the rate matching algorithm. Rate matching can improve the reliability of communication and enhance system performance.
[0034] As an example, Figure 2As shown in the flow chart of rate matching, in the 5G NR system, in the process of rate matching, the data channel is first channel coded and interleaved. The process of channel coding and interleaving may include multiple steps, such as cyclic redundancy check (CRC) of TB, code block segmentation, code block CRC, channel coding, rate matching, bit interleaving, code block cascading, etc. Channel coding of the data channel, such as low-density parity check (LDPC) coding or Polar coding, can increase redundancy and thus improve error resistance. Code block segmentation is to divide the data after channel coding into multiple small code blocks to adapt to different transmission conditions, and the receiving end will recombine the code blocks after receiving the signal, for example Figure 2 In the embodiment, TB is divided into coding block #1, coding block #2, and coding block #3, wherein each coding block also has its own CRC check code. Furthermore, the rate of the coded data is adjusted by bit selection and bit repetition operations to match the bandwidth and transmission capacity of the transmission channel. This usually includes operations such as bit puncturing or bit repetition. Bit puncturing and bit repetition refer to reducing redundant bits by bit puncturing or increasing the number of bits by bit repetition according to the actual transmission bandwidth to adjust the data rate. The bits after puncturing or repetition are interleaved and code blocks are cascaded. The interleaving process can improve the ability to resist burst errors. Code block cascading is to merge the coding blocks and re-merge the data after grouping and rate matching.
[0035] Secondly, modulation mapping is performed. For example, the bits after interleaving and code block concatenation are mapped to modulation symbols, and the modulation symbols include, for example, quadrature phase shift keying (QPSK), quadrature amplitude modulation (QAM) such as 16QAM or 64QAM.
[0036] After that, layer mapping, discrete Fourier transform (DFT), precoding, resource element (RE) mapping and orthogonal frequency division multiplexing (OFDM) transformation are performed in sequence. Among them, layer mapping is a multi-antenna technology. DFT is also called spread spectrum precoding and is only used for uplink transmission. Precoding is a multi-antenna multiple input multiple output (MIMO) technology used to implement spatial domain processing. The purpose of RE mapping and OFDM transformation is to be able to transmit data through the physical layer channel.
[0037] Through the above-mentioned rate matching process, it can be ensured that the data can match the bandwidth and transmission conditions of the physical layer during transmission, improve transmission efficiency and reliability, enable the system to operate efficiently and reliably, and thus provide users with a better communication experience.
[0038] In the NR system, each SSB is used for initial access and synchronization. The SSB consists of three parts: primary synchronization signals (PSS), secondary synchronization signals (SSS), and physical broadcast channel (PBCH). For example, Figure 3 As shown in the SSB structure, SSB occupies a total of 4 OFDM symbols in the time domain and a total of 240 subcarriers, i.e., 20 physical resource blocks (PRBs), which are numbered from 0 to 239, in the frequency domain.
[0039] When scheduling downlink channels such as the physical downlink shared channel (PDSCH), if the time-frequency resources allocated for the PDSCH overlap with the time-frequency resources occupied by the SSB, when mapping the downlink data to the PDSCH, it will be punctured based on the resources occupied by the SSB, so that the PDSCH can be scheduled near the resources occupied by the SSB to reduce the scheduling complexity.
[0040] As mentioned above, in the 5G NR system, SSB occupies 4 symbols and 240 subcarriers in the time domain. In each time slot, there may be downlink channels such as physical downlink control channel (PDCCH), PDSCH, etc. transmitted together with SSB. As an example, Figure 4 As shown, the horizontal axis is the time axis and the vertical axis is the frequency axis. In each time slot, for example, 1ms, PDSCH is transmitted on the symbols on the left and right sides of the SSB, and data is also transmitted on the frequencies on the upper and lower sides of the SSB. Otherwise, these frequencies are not used, which will cause a waste of resources. Taking each subcarrier as 15kHz as an example, 240 subcarriers are approximately several megabytes of bandwidth, which is less than the frequency resources that can be scheduled in the system. In order to make full use of frequency resources, data scheduling will be performed near the frequency resources of the symbols occupied by the SSB.
[0041] If there is a conflict between the transmission resources of SSB and the transmission resources of PDSCH (or scheduling resources), for example, all or part of the SSB is being transmitted on the transmission resources of PDSCH, then the PDSCH can be punctured based on this part of the conflicting resources, that is, PDSCH is not transmitted on this part of the conflicting resources, but SSB is transmitted.
[0042] In the 5G NR system, SSB is transmitted by beam scanning. Usually, multiple SSBs need to be sent in a cell to complete a beam scan so that the SSB covers the service range of the entire cell. The SSBs required to complete a beam scan can form an SSB burst set, or SSB burst for short. Usually, the transmission configuration of the SSB burst set in time, frequency or spatial domain is described by the pattern of the SSB burst set. For example, Figure 5 The SSB beam scanning and SSB burst set transmission time are shown, where: Figure 5 (a) in FIG. 1 shows the spatial beams for transmitting each SSB. Figure 5 (b) in FIG. 1 shows the time domain position of each SSB. In different frequency bands and configurations, the pattern of the SSB burst set may be different. For example, in different frequency bands, the maximum number of SSBs that may be included in an SSB burst set may be 4, 8, 64, etc. Figure 5 It is taken as an example that an SSB burst set includes 8 SSBs, namely SSB 0 to SSB 7. As an example, Table 1 shows the pattern information of SSB transmission under different sub-carrier spacings (sub-carrier space SCS) of SSB.
[0043] Table 1
[0044]
[0045]
[0046] After the terminal device makes initial access, the terminal device can obtain the pattern information of the SSB transmission. When receiving PDSCH, if the transmission resources of PDSCH include part or all of the transmission resources of SSB, for the current system, SSB is sent periodically. The terminal device can determine whether the transmission resources of PDSCH conflict with the transmission resources occupied by SSB based on the known transmission information of SSB. If the transmission resources of PDSCH conflict with the transmission resources of SSB, the terminal device can know the locations where the conflict exists based on the transmission information of SSB obtained in advance, so as to accurately puncture the PDSCH.
[0047] Since the terminal device will generate high energy consumption when sending SSB, for the purpose of energy saving, SSB should not be sent all the time, but should be sent on demand. In other words, the network device can configure SBB to be sent for a short time, and the transmission of SSB is determined according to the needs. Such SSB is called on-demand SSB.
[0048] The transmission of SSB on demand is targeted at specific terminal devices. The network device determines whether to send SSB and how to send SSB according to the needs of certain terminal devices in the cell. Although the transmission of SSB on demand is targeted at specific terminal devices, the transmission of SSB on demand is carried out in the entire cell, that is, the transmission of SSB on demand is a behavior targeted at the cell, or in other words, the transmission of SSB is a cell-level transmission. Therefore, SSB sent to certain terminal devices may affect the channel transmission of other terminal devices in the cell. For example, when the network device performs data scheduling, it will schedule the time-frequency resources near SSB to the terminal device, and the resources are scheduled to the terminal device supporting SSB on demand. These terminal devices can puncture the channels with which they have resource conflicts based on the resource positions occupied by SSB, thereby achieving data rate matching. These terminal devices include, for example, terminal devices that support SSB on demand, such as terminal devices or other terminal devices that provide SSB on demand services, but do not include terminal devices that do not support SSB on demand, because terminal devices that do not support SSB on demand cannot know that there may be SSB transmissions at these resource positions.
[0049] Here, the terminal device supporting on-demand SSB may be, for example, a terminal device supporting a higher protocol version, such as a terminal device in Release 19 and later versions in NR; the terminal device not supporting on-demand SSB may be, for example, a terminal device supporting a lower protocol version, such as a terminal device in Release 18 and earlier versions in NR. In addition, the terminal device for the on-demand SSB service means that the on-demand SSB is triggered for the terminal device, that is, the on-demand SSB is used for access and / or synchronization of the terminal device, but because the on-demand SSB will be transmitted in the entire cell, its transmission will also affect other terminal devices supporting on-demand SSB, and other terminal devices may not currently have the need to use the on-demand SSB for access and / or synchronization.
[0050] As mentioned above, the difference between on-demand SSB and traditional SSB is that traditional SSB is transmitted periodically, while on-demand SSB is transmitted within a period of time, that is, within the required time, which is equivalent to the transmission resources of on-demand SSB being dynamically or semi-statically scheduled. When the transmission period of traditional SSB is adjusted, the network device notifies the terminal device through broadcast signaling to ensure that after all terminal devices receive the broadcast signaling, the network device modifies the transmission period of SSB. Therefore, when the terminal device detects the downlink channel, the terminal device has obtained the transmission time and frequency position of SSB through broadcast signaling, so that when receiving the downlink channel, it can accurately puncture the PDSCH based on the transmission time and frequency position of SSB to remove the influence of SSB, thereby achieving accurate decoding.
[0051] The transmission of on-demand SSB is not periodic, but is transmitted within a period of time, and only some terminal devices can receive the signaling indicating the start or end of the transmission of on-demand SSB. Currently, it is impossible to determine which terminal devices can receive the signaling. Since the detection of on-demand SSB is a capability of some terminal devices, such as terminal devices that support higher protocol versions, no matter how the signaling indicating the start or end of the transmission of on-demand SSB is designed, other terminal devices, such as terminal devices that support lower protocol versions, cannot receive it. Therefore, the downlink channels of these terminal devices should not be scheduled to resources that overlap with the on-demand SSB, otherwise these terminal devices will not puncture the downlink channels, resulting in decoding errors.
[0052] The transmission of on-demand SSB is for specific terminal devices, but the resources near the on-demand SSB should not be limited to the use of only the specific terminal device. If the terminal device does not need to transmit data, then this part of the resources near the on-demand SSB is wasted, so other terminal devices that support on-demand SSB should not be restricted from using this part of resources. In addition, limiting this part of resources to only terminal devices that provide on-demand SSB services also limits the flexibility of scheduling.
[0053] In order to enable other terminal devices that support on-demand SSB to use resources near the on-demand SSB for channel transmission, other terminal devices should also know the transmission status of the on-demand SSB to facilitate puncturing of channels that have resource conflicts with the on-demand SSB.
[0054] In addition, the configuration and transmission of on-demand SSB also need to be notified to the terminal devices that use on-demand SSB for detection, so that these terminal devices can receive the on-demand SSB at the correct time and frequency position.
[0055] To this end, an embodiment of the present application provides a method for wireless communication, wherein a terminal device receives configuration information sent by a network device, wherein the configuration information includes resource information of an on-demand SSB, so that the terminal device can know the transmission location of the on-demand SSB, thereby accurately measuring the on-demand SSB, and / or reducing the impact of SSB transmission on channel transmission through corresponding operations. For example, based on the transmission resources of the SSB, a data channel and / or control channel that has a resource conflict with the SSB can be punctured to avoid problems such as decoding errors.
[0056] The following, combined Figure 6 , the technical solution of the embodiments of the present application is introduced in detail.
[0057] Figure 6 A flowchart of a wireless communication method provided in an embodiment of the present application. Figure 6 The method 600 shown may be executed by a terminal device and a network device.
[0058] See also Figure 6 , in step 610, the network device sends configuration information to the terminal device.
[0059] Accordingly, in step 620, the terminal device receives the configuration information sent by the network device.
[0060] The configuration information includes resource information of the SSB. In the following, the SSBs described are all on-demand SSBs.
[0061] Optionally, the resource information of the SSB can be used by the terminal device to puncture the data channel and / or the control channel, but the embodiments of the present application are not limited thereto, and the resource information of the SSB may also be used to perform other operations, such as for the terminal device to detect the SSB. Here, the data channel and / or control channel that needs to be punctured refers to a channel whose transmission resources have a resource conflict (or at least partially overlap) with the transmission resources of the SSB.
[0062] The data channel includes, for example, downlink channels such as PDSCH, and the control channel includes, for example, downlink channels such as PDCCH. Of course, for the side link (SL), the data channel may also include uplink channels such as physical uplink shared channel (PUSCH), and the control channel may also include uplink channels such as physical uplink control channel (PUCCH).
[0063] The following describes the SSB resource information carried in the configuration information.
[0064] In some implementations, the resource information of the SSB includes one or more of the following: frequency information of the SSB; the position of the SSB in the SSB burst set; period information of the SSB; the subcarrier spacing of the SSB; the bandwidth of the SSB; the downlink transmit power of the SSB; and the physical cell identifier of the SSB (e.g., the cell identifier of the secondary cell).
[0065] The SSB position in the SSB burst set may be used to determine the position of the time domain resources occupied by the SSB. For example, the SSB position in the SSB burst set may be represented by an instruction similar to SSB position burst (ssb-PositionsInBurst).
[0066] The frequency information of SSB can be used to determine the location of the frequency domain resources occupied by SSB. For example, the frequency information of SSB includes the offset of the lowest frequency position of SSB relative to the predetermined frequency, or includes the offset of the highest frequency position of SSB relative to the predetermined frequency. Further, combined with the information of the bandwidth of SSB, the location of the frequency domain resources occupied by SSB can be determined.
[0067] The predetermined frequency can be determined, for example, based on: a specific frequency position in the system; and / or a certain frequency position of the SSB of the primary cell (PCell) of the terminal device, such as the lowest frequency position or the highest frequency position of the SSB.
[0068] Among them, the specific frequency position in the system can be, for example, the position of point A of the system. Point A, as one of the important benchmark reference points in the system, is usually used for the allocation and marking of frequency domain resources. The position of the frequency domain resources used to transmit SSB in the primary cell is usually different from the position of the frequency domain resources used to transmit SSB in the secondary cell (SCell), but the frequency domain positions of the two are relatively close. As an example, the terminal device determines the lowest frequency position of the SSB in the secondary cell based on the lowest frequency position of the SSB in the primary cell. Since the offset between the lowest frequency position of the SSB in the secondary cell and the lowest frequency position of the SSB in the primary cell is usually not large, it can be represented by fewer bits, thereby saving the bit overhead of the configuration information.
[0069] For terminal devices with the same primary cell, the secondary cells they are currently in may be different. When indicating the location of the SSB frequency domain resources by the lowest or highest frequency domain position of the secondary cell, different values may be configured for different terminal devices. Therefore, the network device can send different configuration information carrying SSB resource information to each terminal device.
[0070] In some implementations, the configuration information is carried in one or more of the following: radio resource control (RRC) signaling; multicast signaling; broadcast signaling. Among them, the configuration information carried in the RRC signaling can also be associated with (or correspond to) a terminal device, that is, RRC signaling is sent to different terminal devices to carry corresponding configuration information. For example, for the above-mentioned scenario of indicating the location of the frequency domain resource of the SSB by the lowest or highest frequency domain position of the secondary cell, the frequency information of the SSB carried in the RRC may be different. The multicast signaling and / or broadcast signaling can be, for example, high-layer signaling.
[0071] In some implementations, the resource information of SSB is one of the multiple resource information included in the configuration information, and the configuration information also includes resource serial numbers corresponding to the multiple resource information. As an example, the configuration information sent by the network device may include two types of resource information of SSB, and the corresponding resource serial numbers are #1 and #2, respectively. The positions of the time domain resources and / or frequency domain resources of SSB in the two types of resource information may be different. The terminal device may puncture the channel based on the two types of resource information indicated by #1 and #2, or the terminal device may puncture the channel based on the resource information indicated by number 1 or number 2 based on the instruction of the network device.
[0072] The following uses the configuration information used to puncture a data channel and / or a control channel as an example to describe how a terminal device punctures a data channel and / or a control channel based on the configuration information.
[0073] In some implementations, method 600 further includes, the terminal device receiving first information sent by the network device. The first information may be used, for example, to determine a transmission time of the SSB. The transmission time of the SSB may be used, for example, by the terminal device to determine a time for puncturing a data channel and / or a control channel, and may also be used by the terminal device to determine a time for performing measurements based on the SSB.
[0074] The first information is described in detail below.
[0075] In some implementations, the first information may include one or more of the following: an SSB activation indication; indication information for indicating that the SSB is activated at the end of a predetermined time after the first information; indication information for indicating that the SSB starts transmission at the first resource location for transmitting the SSB after the first information; information on the start time of the SSB transmission; information on the end time of the SSB transmission; information on the duration of the SSB transmission; duration information of a timer for recording the duration of the SSB; information on the number of cycles of the SSB transmission (i.e., how many cycles the SSB is transmitted continuously); period information of the SSB; update information on the period of the SSB (e.g., modifications or changes relative to the last configured SSB period); indication information for indicating that the SSB will stop transmitting; secondary cell status information carried in the secondary cell configuration information, and the secondary cell status information indicates activation; reporting time of the measurement report of the terminal device, the reporting time being used to determine the end time of the SSB transmission.
[0076] Among them, for the case where the first information indicates that the SSB is activated at the end of the preset duration after the first duration, it is considered that the first information can be sent by the primary cell to the terminal device, and there may be a synchronization error between the primary cell and the secondary cell transmitting the SSB. For example, the preset duration can be determined based on the synchronization error.
[0077] The transmission start time and / or transmission end time of the above-mentioned SSB can be expressed in the form of absolute time or relative time. For example, the transmission start time and / or transmission end time can be an absolute time or a relative difference relative to a specific time.
[0078] In the case where the first information includes information on the number of SSB transmission cycles, since the information on the number of SSB transmission cycles is smaller in value than other time information, the number of bits required to represent the number of cycles is also smaller, thereby saving the load in the first information.
[0079] For the case where the first information indicates that the SSB is about to stop transmitting, optionally, the terminal device can determine the specific time when the SSB is about to stop transmitting based on a pre-agreed time or a time notified by the network device through other information, or determine how long to wait for the SSB to stop transmitting upon receiving the first information.
[0080] The secondary cell configuration information is used to configure the secondary cell for the terminal device, for example, including configuration information related to the secondary cell such as frequency, etc. The secondary cell configuration information also includes secondary cell status information, wherein when the secondary cell status information is indicated as activated, it means that the secondary cell is immediately activated when the secondary cell configuration information is received. At this time, the transmission of SSB can also be activated, that is, the transmission of SSB can be started immediately.
[0081] Optionally, the end time of SSB is associated with a measurement report generated by the terminal device based on the SSB measurement results. For example, the end time of SSB can be determined based on the reporting time of the measurement report, such as a certain time position before or after the reporting time of the measurement report is the transmission end time of SSB.
[0082] Optionally, when the terminal device determines that the current SSB is activated (or, activates the transmission of the SSB) based on the first information, the terminal device punctures the data channel and / or the control channel based on the resource information of the SSB when receiving the first information. For another example, when the first information indicates SSB deactivation (or, deactivates the transmission of the SSB), the terminal device will wait until the second information sent by the network device is received, and puncture the data channel and / or the control channel based on the resource information of the SSB. The second information can be used to indicate SSB activation. That is, when the network device determines to activate the transmission of the SSB, it sends the second information to the terminal device, so that the terminal device knows that it can perform corresponding puncturing operations based on the resource information of the SSB.
[0083] As an example, the configuration information includes the resource information of SSB and the first information. When the terminal device receives the configuration information, it can determine when to start using the SSB resource information in the configuration information for puncturing based on the first information. If the first information indicates that the current SSB is activated, the terminal device punctures the channel transmitted on the nearby resources based on the resource information of the SSB; if the first information indicates that the current SSB is deactivated, the terminal device may not puncture the channel transmitted on the nearby resources first, but puncture the channel based on the resource information of the SSB when receiving the second information sent by the network device.
[0084] The first information may be, for example, pre-agreed, such as specified by a protocol; or, the first information may be sent by a network device, such as carried on one or more of the following: configuration information carrying resource information of the SSB; secondary cell configuration information; SSB measurement configuration information. The SSB measurement configuration information includes relevant information used by the terminal device to measure the SSB and report the measurement results, such as information on the reporting time of the above-mentioned measurement results.
[0085] In other implementations, the terminal device may determine when to start puncturing the data channel and / or control channel using the SSB resource information in the configuration information based on the object served by the SSB.
[0086] For example, when the terminal device is not a terminal device of the SSB service, the terminal device performs puncturing on the data channel and / or the control channel based on the resource information of the SSB when receiving the configuration information sent by the network device. For another example, when the terminal device is a terminal device of the SSB service, the terminal device performs puncturing on the data channel and / or the control channel based on the resource information of the SSB when receiving the second information sent by the network device.
[0087] Here, the terminal device served by SSB means that the SSB is triggered for the terminal device, that is, the SSB is used for the terminal device to access and / or synchronize, etc., but the network device will send the SSB in the entire cell. Therefore, the transmission of the SSB will also affect other terminal devices, and other terminal devices may not currently have the need to use SSB for access and / or synchronization. Here, other SSBs are not terminal devices served by SSB.
[0088] Assume that both terminal device 1 and terminal device 2 in the secondary cell support on-demand SSB, and the network device configures the above-mentioned SSB resource information for terminal device 1 and terminal device 2. If the SSB currently sent by the network device is for serving terminal device 1, that is, terminal device 1 currently needs to use the SSB for access and / or synchronization, etc., then terminal device 1 can perform puncturing on the channel transmitted on the nearby resources based on the configured SSB resource information when the network device subsequently sends the second information, and may not perform puncturing on the channel when the second information is not received. Terminal device 2 may not know that the network device has triggered the transmission of SSB for terminal device 1, but in order to avoid the SSB from affecting its channel transmission, terminal device 2 can start to perform puncturing on the channel transmitted on the nearby resources based on the SSB resource information when receiving the SSB resource information configured by the network device. In other words, terminal device 2 can directly puncture the channel without considering the actual transmission of SSB, because in the actual transmission situation, it may not be possible to notify terminal device 2 when there is SSB transmission.
[0089] The second information is described in detail below.
[0090] In some implementations, the second information may include one or more of the following: a resource sequence number corresponding to the resource information of the SSB; a transmission start time of the SSB; and an SSB index (SSB index) of the SSB.
[0091] Among them, the resource serial number is used to indicate the resource information of the SSB associated with it. Based on the resource serial number, the terminal device can determine to use the corresponding resource information to perform the corresponding punching operation.
[0092] The transmission start time of SSB is expressed in the form of absolute time or relative time, for example. The absolute time may be, for example, the frame number or time slot number of the wireless frame where the transmission start time of SSB is located. The relative time is the offset of the transmission start time relative to the predetermined time. The predetermined time is, for example, the time when the terminal device receives the physical layer signaling, and the physical layer signaling is, for example, the signaling carrying the second information. As an example, the terminal device may determine that a number of milliseconds or a number of time slots after receiving the physical layer signaling is the start transmission time of SSB.
[0093] In some implementations, the second information is carried in a secondary cell activation signaling, or carried in a physical layer signaling. The secondary cell activation signaling is, for example, a MAC signaling. The physical layer signaling includes, for example, a group common signaling, and the group common signaling may be, for example, group common downlink control message (DCI), etc.
[0094] As an example, assuming that both terminal device 1 and terminal device 2 in the secondary cell support on-demand SSB, the second information is carried in the secondary cell activation signaling of terminal device 1. Figure 7 As shown, the secondary cell activation signaling sent by the network device to the terminal device 1 carries the second information. When receiving the second information, the terminal device 1 knows that there is SSB transmission, and thus starts to perform the corresponding punching operation based on the above configuration information sent by the network device. However, the terminal device 2 cannot receive the second information. At this time, the terminal device 2 may have just received the above configuration information sent by the network device, and does not know whether the on-demand SSB is being transmitted. Therefore, the terminal device 2 can directly perform the corresponding punching operation based on the configuration information.
[0095] For another example, assuming that both terminal device 1 and terminal device 2 in the secondary cell support on-demand SSB, and the second information is carried in the group-common DCI, since both terminal device 1 and terminal device 2 can receive the group-common DCI, terminal device 1 and terminal device 2 can perform corresponding punching operations based on the configuration information when receiving the second information carried in the group-common DCI.
[0096] In some implementations, method 600 further includes the terminal device sending feedback information of the second information to the network device; accordingly, the network device receives the feedback information sent by the terminal device. The feedback information may be, for example, HARQ-ACK, which is used to trigger the network device to send SSB, that is, after receiving the feedback information of the second information sent by the terminal device, the network device sends SSB to the terminal device.
[0097] In some implementations, the terminal device may puncture the data channel and / or control channel based on the resource information of the SSB when the SSB is detected based on the resource information of the SSB. However, when the terminal device does not detect the SSB based on the resource information of the SSB, the data channel and / or control channel is not punctured. In this case, the terminal device may not be a terminal device for the SSB service, for example. The detection here includes, for example, matching and other related operations. If the match is successful, it means that there is SSB transmission on the resource. If the match is not successful, it means that there is no SSB transmission on the resource.
[0098] In some implementations, method 600 may further include, in one or more of the following cases, the terminal device determines that the SSB is deactivated: the terminal device receives an SSB deactivation indication; a timer for recording the duration of the SSB times out; the terminal device receives a new SSB activation indication. Here, the terminal device may, for example, include all terminal devices supporting on-demand SSB in the secondary cell. When determining that the SSB is deactivated, the terminal device may stop detecting the SSB and stop puncturing the data channel and / or the control channel.
