[0027] The technical solutions in the present application will be described below with reference to the accompanying drawings.

[0028] Wireless communication system

[0029] FIG. 1 is an example diagram of a system architecture of a wireless communication system 100 to which embodiments of the present application can be applied. The wireless communication system 100 can include a network device 110 and a terminal device 120. The network device 110 can be a device that communicates with the terminal device 120. The network device 110 can provide network coverage for a specific geographic area, and can communicate with the terminal device 120 located in the coverage area. The terminal device 120 can access a network, such as a wireless network, through the network device 110. Optionally, the wireless communication system 100 can further include a network controller, a mobile management entity, and other network entities, which are not limited by embodiments of the present application.

[0030] It should be understood that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as a fifth generation (5G) system or new radio (NR), a long term evolution (LTE) system, an LTE frequency division duplex (FDD) system, an LTE time division duplex (TDD), and the like. The technical solutions provided by the present application can also be applied to future communication systems, such as a sixth generation mobile communication system, a satellite communication system, and the like.

The terminal device in the embodiments of the present application can refer to a device providing voice and / or data connectivity for a user, and can be used to connect people, things and machines, such as handheld devices with wireless connection function, vehicle-mounted devices, etc. The terminal device in the embodiments of the present application can be a mobile phone, a tablet computer (Pad), a notebook computer, a palm computer, 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.

The cellular phone and the smart home device communicate with each other without relaying the communication signals through the base station.

[0033] Rate matching

[0034] In a wireless communication system, rate matching is a process for adjusting the data rate to match the physical layer transmission capability. In the rate matching process, a series of processing is required for the transport block (TB) to adjust its length by the rate matching algorithm to adapt to the transmission capability of the channel. Rate matching can improve the reliability of communication and improve system performance.

[0035] As an example, as shown in the flow chart of rate matching in FIG. 2, in the process of rate matching in the 5G NR system, first, the data channel is channel coded and interleaved. Among them, the process of channel coding and interleaving can 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 concatenation, etc. Among them, channel coding of the data channel, such as low density parity check (LDPC) coding or Polar coding, etc., can increase redundancy and thus improve error correction capability. 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, such as FIG. 2 divides the TB into code block #1, code block #2, code block #3, wherein each code block also has its own CRC check code. Further, the rate of the coded data is adjusted by bit selection and bit repetition operation to match the bandwidth and transmission capability 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 performing puncturing or repetition are interleaved and code block concatenated, interleaving can improve the ability to resist burst errors, and code block concatenation is to merge the code blocks, and the grouped and rate matched data is recombined.

[0036] Secondly, modulation mapping is performed. For example, the bits after interleaving and code block concatenation are mapped to modulation symbols, which include, for example, quadrature phase shift keying (QPSK), quadrature amplitude modulation (QAM) such as 16QAM or 64QAM, etc.

[0037] After that, layer mapping, discrete Fourier transform (DFT), precoding, resource element (RE) mapping, and orthogonal frequency division multiplexing (OFDM) transform are sequentially performed. The layer mapping is a multi-antenna technology. The DFT is also called spread precoding, and is only used for uplink transmission. The precoding is a multiple input multiple output (MIMO) technology, which is used to realize spatial domain processing. The purpose of RE mapping and OFDM transform is to be able to transmit data out through the physical layer channel.

[0038] Through the above rate matching process, it can be ensured that the data can match the bandwidth and transmission conditions of the physical layer during transmission, improve the transmission efficiency and reliability, and enable the system to operate efficiently and reliably, thereby providing users with a better communication experience.

[0039] In the NR system, each SSB is used for initial access and synchronization, and the SSB is composed of three parts of primary synchronization signals (PSS), secondary synchronization signals (SSS), and physical broadcast channel (PBCH). As an example, as shown in FIG. 3, the SSB structure, the SSB occupies 4 OFDM symbols in the time domain, and 240 subcarriers, i.e., 20 physical resource blocks (PRBs), in the frequency domain, numbered from 0 to 239.

[0040] When scheduling a downlink channel such as a physical downlink shared channel (PDSCH), in the case of overlap between the time-frequency resources allocated for the PDSCH and the time-frequency resources occupied by the SSB, when mapping the downlink data to the PDSCH, the resources occupied by the SSB 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.

[0041] As mentioned before, in 5G NR system, SSB occupies 4 symbols and 240 subcarriers in time domain. In each time slot, there can be downlink channels such as physical downlink control channel (PDCCH), PDSCH, etc. transmitted together with SSB. As an example, as shown in FIG. 4, with time axis horizontally and frequency axis vertically, in each time slot, e.g. 1 ms, PDSCH is transmitted on the symbols left and right of SSB, and data is also transmitted on the frequencies above and below SSB, otherwise, these frequencies are not utilized and resource is wasted. Taking 15 kHz per subcarrier as an example, 240 subcarriers are about several MHz 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 is performed near the frequency resources of the symbols occupied by SSB.

[0042] If the transmission resources of SSB and the transmission resources (or scheduling resources) of PDSCH conflict, e.g. there is SSB transmitted on the transmission resources of PDSCH, then PDSCH can be punctured based on the part of the conflicting resources, i.e. PDSCH is not transmitted on the part of the conflicting resources, and SSB is transmitted instead.

[0043] In 5G NR system, SSB is transmitted through beam sweeping, and multiple SSBs are usually transmitted in a cell to complete a beam sweep so that SSB covers the service range of the entire cell. The SSBs needed to complete a beam sweep can form an SSB burst set, or simply an SSB burst. Usually, the transmission configuration of SSB burst set in time, frequency or space is described by the pattern of SSB burst set. For example, as shown in FIG. 5, SSB beam sweeping and SSB burst set transmission time, wherein (a) of FIG. 5 shows the spatial beam for transmitting each SSB, and (b) of FIG. 5 shows the time domain position for transmitting each SSB. The pattern of SSB burst set can be different under different frequency bands and configurations. For example, under different frequency bands, the maximum number of SSBs that can be included in an SSB burst set can be 4, 8 and 64, etc. FIG. 5 takes an SSB burst set including 8 SSBs, i.e. SSB 0 to SSB 7, as an example. As an example, Table 1 shows the pattern information of SSB transmission under different sub-carrier space SCS of SSB.

[0044] Table 1

[0045] After the terminal device performs initial access, the terminal device can obtain the pattern information of SSB transmission. When receiving PDSCH, if part or all of the transmission resources of the PDSCH include the transmission resources of the SSB, the SSB is periodically transmitted in the current system, and the terminal device can determine whether the transmission resources of the PDSCH conflict with the transmission resources of the SSB according to the known transmission information of the SSB. If the transmission resources of the PDSCH conflict with the transmission resources of the SSB, the terminal device can know the positions of the conflict according to the obtained transmission information of the SSB, so as to accurately puncture the PDSCH.

[0046] Since the terminal device transmits the SSB, a high energy consumption is generated. For the purpose of energy saving, the SSB should not be transmitted all the time, but should be transmitted on demand. That is, the network device can configure the SBB to be transmitted for a short time, and the transmission of the SSB is determined according to the need. Such SSB is called on-demand SSB.

[0047] The transmission of the on-demand SSB is for specific terminal devices. The network device determines whether to transmit the SSB and how to transmit the SSB according to the needs of some terminal devices in the cell. Although the transmission of the on-demand SSB is for specific terminal devices, the transmission of the on-demand SSB is performed in the entire cell, that is, the transmission of the on-demand SSB is a behavior for the cell, or in other words, the transmission of the SSB is a cell-level transmission. Therefore, the SSB transmitted for some terminal devices can affect the channel transmission of other terminal devices in the cell. For example, when the network device performs data scheduling, the time-frequency resources near the SSB are scheduled to the terminal devices. The resources are scheduled to the terminal devices supporting the on-demand SSB. These terminal devices can puncture the channels that conflict with the resources based on the resource positions occupied by the SSB, so as to realize data rate matching. These terminal devices include, for example, terminal devices supporting the on-demand SSB, such as terminal devices served by the on-demand SSB or other terminal devices, but do not include terminal devices not supporting the on-demand SSB, because the terminal devices not supporting the on-demand SSB cannot know that there may be SSB transmission on the resource positions.

[0048] Here, the terminal device supporting on-demand SSB can 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 can 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 served by on-demand SSB refers to on-demand SSB triggered for the terminal device, i.e., the on-demand SSB is used for access and / or synchronization, etc. of the terminal device, but since the on-demand SSB is transmitted in the entire cell, its transmission will also affect other terminal devices supporting on-demand SSB, and the other terminal devices can not currently have the need to use on-demand SSB for access and / or synchronization, etc.

[0049] As mentioned above, the difference between on-demand SSB and traditional SSB is that the traditional SSB is periodically transmitted, while the on-demand SSB is transmitted in a period of time, i.e., in the time when it is needed, which is equivalent to that the transmission resource of on-demand SSB is dynamically or semi-statically scheduled. When the transmission period of traditional SSB is adjusted, the network device notifies the terminal device through broadcast signaling, so that after all terminal devices receive the broadcast signaling, the network device modifies the transmission period of SSB, etc. Therefore, when detecting the downlink channel, the terminal device has obtained the transmission time and frequency position of SSB through the broadcast signaling, so that when receiving the downlink channel, the terminal device can accurately puncture the PDSCH based on the transmission time and frequency position of SSB, remove the influence of SSB therein, and thus realize accurate decoding.

[0050] The transmission of on-demand SSB is not periodic, but is transmitted in a period of time, and only a part of terminal devices can receive the signaling indicating the start of transmission or the termination of transmission of on-demand SSB, and it is currently not determined which terminal devices can receive the signaling. Since the detection of on-demand SSB is the capability of some terminal devices, such as terminal devices supporting a higher protocol version, no matter how the signaling indicating the start of transmission or the termination of transmission of on-demand SSB is designed, other terminal devices, such as terminal devices supporting a lower protocol version, cannot receive the signaling, and therefore the downlink channel of this part of terminal devices should not be scheduled to the resource overlapping with on-demand SSB, otherwise this part of terminal devices will not puncture the downlink channel and thus decoding error will occur.

[0051] The transmission of on-demand SSB is for a specific terminal device, but the resource near the on-demand SSB should not be limited to the use of the specific terminal device only, if the terminal device has no need for data transmission, then this part of resource near the on-demand SSB is wasted, and therefore the use of this part of resource by other terminal devices supporting on-demand SSB should not be limited. In addition, limiting this part of resource to only allow the terminal device served by on-demand SSB also limits the flexibility of scheduling.

[0052] In order to enable other terminal devices supporting on-demand SSB to also use the resources near the on-demand SSB for channel transmission, the other terminal devices should also know the transmission state of the on-demand SSB, so as to puncture the channel that has resource conflict with the on-demand SSB.

[0053] In addition, the configuration and transmission of the on-demand SSB also need to be notified to the terminal devices that detect using the on-demand SSB, so that these terminal devices can receive the on-demand SSB at the correct time-frequency position.

[0054] To this end, the embodiments of the present application provide a method of wireless communication, a terminal device receives configuration information sent by a network device, the configuration information including resource information of an on-demand SSB, so that the terminal device can know the transmission position 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, the data channel and / or control channel that has resource conflict with the SSB can be punctured based on the transmission resource of the SSB, so as to avoid decoding errors and other problems.

[0055] Hereinafter, the technical solutions of the embodiments of the present application will be described in detail in combination with FIG. 6.

[0056] FIG. 6 is a flowchart of a method of wireless communication provided by the embodiments of the present application. The method 600 shown in FIG. 6 can be performed by a terminal device and a network device.

[0057] Referring to FIG. 6, in step 610, the network device sends configuration information to the terminal device.

[0058] Correspondingly, in step 620, the terminal device receives the configuration information sent by the network device.

[0059] The configuration information includes resource information of the SSB. Hereinafter, the SSBs mentioned are all on-demand SSBs.

[0060] Optionally, the resource information of the SSB can be used by the terminal device to puncture the data channel and / or control channel, but the embodiments of the present application are not limited thereto, and the resource information of the SSB can also be used to perform other operations, such as used by the terminal device to detect the SSB. Here, the data channel and / or control channel that needs to be punctured refers to the channel whose transmission resource has resource conflict (or at least partially overlaps) with the transmission resource of the SSB.

[0061] The data channel includes, for example, a downlink channel such as a PDSCH, and the control channel includes, for example, a downlink channel such as a PDCCH. Of course, for a side link (SL), the data channel can also include an uplink channel such as a physical uplink shared channel (PUSCH), and the control channel can also include an uplink channel such as a physical uplink control channel (PUCCH).

[0062] In the following, the resource information of the SSB carried in the configuration information is described.

[0063] In some implementations, the resource information of the SSB includes one or more of the following: frequency information of the SSB; a position of the SSB in a SSB burst set; periodicity information of the SSB; a subcarrier spacing of the SSB; a bandwidth of the SSB; a downlink transmit power of the SSB; and a physical cell identity of the SSB (e.g., a cell identity of a secondary cell).

[0064] The position of the SSB in the SSB burst set can be used to determine the position of the time domain resource occupied by the SSB. For example, the position of the SSB in the SSB burst set can be represented by an instruction similar to ssb-PositionsInBurst.

[0065] The frequency information of the SSB can be used to determine the position of the frequency domain resource occupied by the SSB. For example, the frequency information of the SSB includes an offset of the lowest frequency position of the SSB relative to a predetermined frequency, or includes an offset of the highest frequency position of the SSB relative to the predetermined frequency. Further, in combination with the information of the bandwidth of the SSB, the position of the frequency domain resource occupied by the SSB can be determined.

[0066] The predetermined frequency can be determined based on, for example, a certain 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.

[0067] The specific frequency position in the system may be, for example, the position of point A of the system, which is one of the important reference points in the system and is usually used for allocation and labeling of frequency domain resources. The position of the frequency domain resource used for transmitting the SSB in the primary cell is usually different from the position of the frequency domain resource used for transmitting the 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, fewer bits can be used to represent the offset, thereby saving the bit overhead of the configuration information.

[0068] For terminal devices with the same primary cell, the secondary cell in which the terminal device is currently located may be different. When the position of the frequency domain resource of the SSB is indicated 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 for each terminal device.

[0069] In some implementations, the configuration information is carried in one or more of the following: radio resource control (RRC) signaling; multicast signaling; broadcast signaling. The configuration information carried in the RRC signaling may, for example, also be associated with (or said to correspond to) the terminal device, that is, the RRC signaling carrying the corresponding configuration information is sent for different terminal devices respectively. For example, in the scenario described above where the position of the frequency domain resource of the SSB is indicated 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 may, for example, be high-layer signaling.

[0070] In some implementations, the resource information of the SSB is one of a plurality of resource information included in the configuration information, and the configuration information further includes resource sequence numbers corresponding to the plurality of resource information. As an example, the configuration information sent by the network device may include two resource information of the SSB, and the corresponding resource sequence numbers are #1 and #2 respectively. The positions of the time domain resources and / or frequency domain resources of the SSB in the two resource information may be different. The terminal device may puncture the channel based on the two 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 indication of the network device.

[0071] The following describes how the terminal device performs puncturing on the data channel and / or control channel based on the configuration information, taking the case of using the configuration information for puncturing the data channel and / or control channel as an example.

[0072] In some implementations, the method 600 further includes that the terminal device receives first information sent by the network device. The first information may, for example, be used to determine the transmission time of the SSB. The transmission time of the SSB may, for example, be used by the terminal device to determine the time for puncturing the data channel and / or control channel, and of course, may also be used by the terminal device to determine the time for measuring based on the SSB.

[0073] The following describes the first information in detail.

[0074] In some implementations, the first information may include one or more of the following: an SSB activation indication; indication information indicating that the SSB is activated at the end of a predetermined time duration after the first information; indication information indicating that the SSB starts transmission at the first resource position for transmitting the SSB after the first information; information of the transmission start time of the SSB; information of the transmission end time of the SSB; information of the transmission duration of the SSB; time duration information of a timer recording the duration of the SSB; information of the number of periods of the SSB transmission (i.e., how many periods of continuous transmission of the SSB); period information of the SSB; update information of the period of the SSB (e.g., modification or change relative to the last configured SSB period); indication information indicating that the SSB will stop transmission; secondary cell state information carried in the secondary cell configuration information, and the secondary cell state information indicating activation; and reporting time of the measurement report of the terminal device, which is used to determine the transmission end time of the SSB.

[0075] In the case where the first information indicates that the SSB is activated at the end of a preset time duration after the first time duration, it is considered that the first information may 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 time duration may be determined based on the synchronization error.

[0076] The transmission start time and / or transmission end time of the SSB described above may be represented by absolute time or relative time, for example, the transmission start time and / or transmission end time may be absolute time or a relative difference between the absolute time and a certain specific time.

[0077] In the case where the first information includes the information of the number of periods of the SSB transmission, since the information of the number of periods of the SSB transmission has a smaller value relative to other time information, the number of bits required for representing the number of periods is also smaller, thereby saving the load in the first information.

[0078] For the case that the first information indicates that the SSB is going to stop transmission, optionally, the terminal device can determine, based on a time agreed in advance or informed by the network device through other information, at what time the SSB will stop transmission, or in other words, determine how long to wait after receiving the first information before the SSB stops transmission.

[0079] The secondary cell configuration information is used to configure a secondary cell for the terminal device, for example, including secondary cell related configuration information such as frequency, etc., and the secondary cell configuration information also includes secondary cell state information, wherein the secondary cell state information is indicated as activated, indicating that the secondary cell is activated immediately upon receiving the secondary cell configuration information. At this time, the transmission of the SSB can also be activated, i.e., immediately start transmitting the SSB.

[0080] Optionally, the end time of the SSB is associated with a measurement report generated by the terminal device based on the SSB measurement result, for example, the end time of the 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 as the end time of the SSB transmission.

[0081] Optionally, in the case that the terminal device determines that the current SSB is activated (or in other words, activates the transmission of the SSB) based on the first information, the terminal device performs puncturing on the data channel and / or control channel based on the resource information of the SSB upon receiving the first information. For another example, in the case that the first information indicates that the SSB is deactivated (or in other words, deactivates the transmission of the SSB), the terminal device waits until receiving the second information sent by the network device, and then performs puncturing on the data channel and / or control channel based on the resource information of the SSB. The second information can be used to indicate the activation of the SSB. That is, the network device sends the second information to the terminal device when determining to activate the transmission of the SSB, so that the terminal device knows that it can perform the corresponding puncturing operation based on the resource information of the SSB.

[0082] As an example, taking the case that the configuration information includes the resource information of the SSB and the first information as an example. Upon receiving the configuration information, the terminal device can determine when to start puncturing based on the resource information of the SSB in the configuration information based on the first information therein. If the first information indicates that the current SSB is activated, the terminal device punctures the channel transmitted on the nearby resource based on the resource information of the SSB; if the first information indicates that the current SSB is deactivated, the terminal device can not puncture the channel transmitted on the nearby resource first, but punctures the channel based on the resource information of the SSB upon receiving the second information sent by the network device.

[0083] The first information may be pre-agreed, for example, agreed by a protocol, or may be sent by the network device, for example, carried in one or more of the following: the configuration information of the above-mentioned SSB resource information, the secondary cell configuration information, and the SSB measurement configuration information. The SSB measurement configuration information includes relevant information for the terminal device to measure the SSB and report the measurement result, for example, includes the above-mentioned information of the reporting time of the measurement result.

[0084] In some other implementations, the terminal device may determine when to start puncturing the data channel and / or the control channel based on the SSB resource information in the configuration information, according to the object served by the SSB.

[0085] For example, in the case that the terminal device is not the SSB-served terminal device, the terminal device punctures the data channel and / or the control channel based on the SSB resource information upon receiving the configuration information sent by the network device. For another example, in the case that the terminal device is the SSB-served terminal device, the terminal device punctures the data channel and / or the control channel based on the SSB resource information upon receiving the second information sent by the network device.

[0086] Here, the SSB-served terminal device refers to the SSB 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 transmits the SSB in the entire cell, so the transmission of the SSB also affects other terminal devices, which may not currently have the need to access and / or synchronize using the SSB. Here, the other SSB is not the SSB-served terminal device.

[0087] Suppose that the terminal device 1 and the terminal device 2 in the secondary cell both support on-demand SSB, and the network device configures the terminal device 1 and the terminal device 2 with the above-mentioned SSB resource information. If the SSB currently transmitted by the network device is for serving the terminal device 1, that is, the terminal device 1 currently needs to access and / or synchronize using the SSB, etc., the terminal device 1 may puncture the channel transmitted on the nearby resource based on the configured SSB resource information upon the network device subsequently sending the second information, and may not puncture the channel without receiving the second information. The terminal device 2 may not know that the network device triggers the transmission of the SSB for the terminal device 1, but in order to avoid the influence of the SSB on its channel transmission, the terminal device 2 may start to puncture the channel transmitted on the nearby resource based on the SSB resource information upon receiving the SSB resource information configured by the network device. That is, the terminal device 2 may directly puncture the channel without considering the actual transmission of the SSB, because the actual transmission may not have enough time to inform the terminal device 2 when the SSB is transmitted.

[0088] The second information is described in detail as follows.

[0089] In some implementations, the second information can comprise 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; an SSB index of the SSB.

[0090] The resource sequence number is used to indicate the resource information of the SSB associated therewith, and the terminal device can determine to use the corresponding resource information to perform the corresponding puncturing operation based on the resource sequence number.

[0091] The transmission start time of the SSB is represented in the form of, for example, absolute time or relative time. The absolute time can be, for example, a frame sequence number or a time slot number of a radio frame in which the transmission start time of the SSB is located. The relative time is an offset of the transmission start time relative to a predetermined time. The predetermined time can be, for example, a time at which the terminal device receives a physical layer signaling, such as a signaling carrying the second information. As an example, the terminal device can determine a number of milliseconds or a number of time slots after receiving the physical layer signaling as the start transmission time of the SSB.

[0092] In some implementations, the second information is carried in a secondary cell activation signaling or in a physical layer signaling. The secondary cell activation signaling can be, for example, a MAC signaling. The physical layer signaling can comprise, for example, a group common signaling, such as a group common downlink control information (DCI).

[0093] As an example, assuming that a terminal device 1 and a terminal device 2 in a secondary cell both support on-demand SSB, the second information is carried in a secondary cell activation signaling of the terminal device 1. As shown in FIG. 7, the second information is carried in the secondary cell activation signaling sent by a network device to the terminal device 1. Upon receiving the second information, the terminal device 1 knows that there is a transmission of SSB, and thus starts to perform the corresponding puncturing operation based on the configuration information sent by the network device. The terminal device 2 cannot receive the second information, and at this time, the terminal device 2 can have just received the configuration information sent by the network device, and does not know whether the on-demand SSB is being transmitted, and thus the terminal device 2 can directly perform the corresponding puncturing operation based on the configuration information.

[0094] As another example, assuming that a terminal device 1 and a terminal device 2 in a secondary cell both support on-demand SSB, the second information is carried in a group common DCI. Since the terminal device 1 and the terminal device 2 can both receive the group common DCI, the terminal device 1 and the terminal device 2 can perform the corresponding puncturing operation based on the configuration information upon receiving the second information carried in the group common DCI.

[0095] In some implementations, the method 600 further includes that the terminal device sends feedback information of the second information to the network device; and accordingly, the network device receives the feedback information sent by the terminal device. The feedback information may, for example, be a HARQ-ACK, which is used to trigger the network device to send the SSB, that is, the network device sends the SSB to the terminal device after receiving the feedback information of the second information sent by the terminal device.

[0096] In some implementations, the terminal device may, in a case where the terminal device detects the SSB based on the resource information of the SSB, puncture the data channel and / or the control channel based on the resource information of the SSB. In a case where the terminal device does not detect the SSB based on the resource information of the SSB, the terminal device does not puncture the data channel and / or the control channel. The terminal device may, for example, not be a terminal device served by the SSB. The detection may, for example, include matching and the like, and a match indicates that there is SSB transmission on the resource, and a non-match indicates that there is no SSB transmission on the resource.

[0097] In some implementations, the method 600 further includes that the terminal device determines SSB deactivation in one or more of the following cases: the terminal device receives an SSB deactivation indication; a timer used to record the duration of the SSB times out; and the terminal device receives a new SSB activation indication. The terminal device may, for example, include all terminal devices that support on-demand SSB in a secondary cell. After determining the SSB deactivation, the terminal device may stop detecting the SSB and stop puncturing the data channel and / or the control channel.
