Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and apparatus, terminal equipment and network equipment. Background Art

[0002] Subband full duplex (SBFD) refers to the use of subbands to divide uplink and downlink transmission in the frequency domain, so that uplink and downlink transmission can be carried out at the same time while using frequency division to reduce interference. For the network equipment side, it can support downlink transmission and uplink reception in different subbands of frequency domain resources at the same time. For the terminal equipment side, it can support downlink reception in the downlink subband or uplink transmission in the uplink subband.

[0003] At present, with the rapid growth of uplink service demand, there are higher requirements for uplink coverage, rate and latency. The synchronization signal and physical broadcast channel (PBCH) block (SSB) is a downlink signal with a higher priority. Since the configuration of SSB and uplink subband is periodic, and the two periods may be different and overlap, uplink subband can be configured on SSB. However, if uplink transmission is performed on the uplink subband configured by SSB symbols, it may interfere with SSB detection or cell switching, so how to reduce the interference caused by uplink transmission on SSB symbols is an urgent problem to be solved. Summary of the invention

[0004] The present application provides a communication method and apparatus, a terminal device and a network device, which can reduce the interference caused by uplink transmission on SSB symbols.

[0005] In the first aspect, a communication method of the present application can be applied to a terminal device, or to a device in a terminal device (e.g., a chip, or a chip system, or a circuit), or a device that can be used with a terminal device. The following description is based on the application to a terminal device as an example. The method may include: determining whether SSB symbols in all SSB burst sets within a first time period can be uplink transmitted, or whether symbols in a non-cell defining (NCD)-SSB can be uplink transmitted.

[0006] It can be seen that, unlike the prior art which defines which specific SSB symbols in an SSB burst set can be used for uplink transmission, the impact on the initial access terminal device is not considered (on the same SSB burst set, the uplink transmission of the terminal device that has been accessed will interfere with the reception of SSB by the initial access terminal device). In an embodiment of the present application, a time period (such as a first time period) can be defined, and multiple SSB burst sets are covered in this time period. Taking the SSB burst set as a unit, it is determined whether the SSB symbols in all SSB burst sets in the time period can be used for uplink transmission, wherein at least one SSB symbol in the SSB burst set in the first time period is not used for uplink transmission. It can be ensured that at least one SSB in the SSB burst set is not used for uplink transmission of other terminal devices but for detection of the SSB of the initial access terminal device within the time period, so as not to be interfered with by the uplink transmission, thereby ensuring the performance of the initial access and reducing the interference caused by uplink transmission on the SSB symbol. Alternatively, for a terminal device in a connected state, it is possible to determine whether the symbols in the NCD-SSB can be used for uplink transmission. Since the priority of the NCD-SSB is low and it will not be used for cell selection and reselection, etc., the consequences caused by interference caused by uplink transmission on the SSB symbol can be reduced. Therefore, in an embodiment of the present application, the terminal device can clarify whether the SSB symbol (which can be understood as the uplink subband of the SSB symbol) can be used for uplink transmission, thereby achieving the beneficial effect of reducing the interference caused by uplink transmission on the SSB symbol.

[0007] In a possible implementation, a time period of the SSB burst set is smaller than the first time period.

[0008] Since the terminal device that initially accesses receives SSB periodically, the time period of the SSB burst set can be smaller than the first time period, and the first time period will contain multiple SSB burst sets. In this way, the performance of initial access can be guaranteed by only ensuring that the signal of at least one SSB burst set in the first time period is not interfered by the uplink transmission. Therefore, when the time period of the SSB burst set is smaller than the first time period, a first time period will contain multiple SSB burst sets. It can be indicated which SSB burst sets in the first time period can be uplinked and which cannot be uplinked, thereby reducing the interference caused by uplink transmission on SSB symbols.

[0009] In a possible implementation, the first time period is the time period of a default SSB burst set configured for an initial access terminal device.

[0010] The first time period is set to the time period of the default SSB burst set configured for the terminal device for initial access. For example, the period of the default SSB burst set of the terminal device for initial access is 20ms. Therefore, the first time period can be set to 20ms. This ensures that at least one SSB burst set signal of the initial access terminal device is not interfered by the uplink transmission within 20ms, thereby ensuring the performance of the initial access and reducing the interference caused by uplink transmission on the SSB symbol.

[0011] A possible implementation method, wherein determining whether SSB symbols in all SSB burst sets within a first time period can be uplink transmitted includes: receiving indication information; and determining whether SSB symbols in all SSB burst sets within the first time period can be uplink transmitted based on the indication information.

[0012] A possible implementation method is that the indication information is used to indicate whether the SSB symbol of each SSB burst set within the first time period can be transmitted uplink; determining whether the SSB symbols in all SSB burst sets within the first time period can be transmitted uplink according to the indication information includes: determining whether the SSB symbol of each SSB burst set within the first time period can be transmitted uplink according to the indication information.

[0013] The indication information may be used to indicate whether the SSB symbol of each SSB burst set in the first time period can be transmitted uplink, so that the terminal device determines whether the SSB symbols in all SSB burst sets in the first time period can be transmitted uplink according to the indication information. For example, the first time period includes multiple SSB burst sets, and the indication information may be used as a unit of SSB burst sets, and may indicate whether the SSB symbol of each SSB burst set can be transmitted uplink through multiple bits.

[0014] In a possible implementation, the indication information indicates an index of a first SSB burst set, and the first SSB burst set is any SSB burst set of all SSB burst sets within the first time period; determining whether the SSB symbols in all SSB burst sets within the first time period can be uplink transmitted according to the indication information includes: determining that the SSB symbols in the first SSB burst set cannot be uplink transmitted according to the index of the first SSB burst set, and that the SSB symbols in other SSB burst sets except the first SSB burst set within the first time period can be uplink transmitted.

[0015] Since at least one SSB symbol in the SSB burst set in the first time period is not used for uplink transmission, the index of the SSB burst set that can / cannot be uplinked can be indicated by the indication information, so that the terminal device can determine that the SSB symbol in the SSB burst set corresponding to the index is not for uplink transmission, while the SSB symbols in other SSB burst sets are used for uplink transmission. Compared with indicating whether the SSB symbol of each SSB burst set in the first time period can be uplinked, indicating the index of the SSB burst set that cannot be uplinked can reduce signaling overhead.

[0016] In a possible implementation, the indication information is also used to indicate whether each SSB symbol in the SSB burst set capable of uplink transmission can be transmitted uplink.

[0017] In the above implementation, the indication information can indicate whether uplink transmission can be performed in units of SSB burst sets, for example, indicating whether the SSB symbol of each SSB burst set in the first time period can be uplink transmitted, or indicating the index of the SSB burst set that can / cannot be uplink transmitted. Further optionally, for the SSB burst set that can perform uplink transmission, the indication information can also be indicated in units of SSB symbols, and can also indicate whether each SSB symbol therein can be uplink transmitted, so that the terminal device can determine the specific SSB symbol that can be used for uplink transmission.

[0018] In a possible implementation, the indication information is also used to indicate the index of the SSB symbol that can be used for uplink transmission in the SSB burst set that can be used for uplink transmission.

[0019] In the above implementation, the indication information can indicate whether uplink transmission can be performed in units of SSB burst sets, for example, indicating whether the SSB symbol of each SSB burst set in the first time period can be uplink transmitted or indicating the index of the SSB burst set that can / cannot be uplink transmitted. Further, optionally, for the SSB burst set that can perform uplink transmission, the index of the SSB symbol that can / cannot be uplink transmitted within the SSB burst set that can perform uplink transmission can also be indicated, so that the terminal device can determine the specific SSB symbol that can be uplink transmitted.

[0020] In a possible implementation, a first value of the indication information is used to indicate that uplink transmission is possible, and a second value of the indication information is used to indicate that uplink transmission is not possible, and the first value is different from the second value.

[0021] In a possible implementation manner, the indication information is carried by one of downlink control information (downlink control information, DCI), system information, and radio resource control (radio resource control, RRC) messages.

[0022] In a possible implementation, determining whether the symbols in the NCD-SSB can be uplink transmitted includes: determining whether the symbols in the NCD-SSB can be uplink transmitted according to pre-configuration information of the NCD-SSB.

[0023] When pre-configuring NCD-SSB, you can configure whether the symbols in NCD-SSB can be transmitted uplink. This information can be pre-defined or pre-negotiated between the network device and the terminal device. The terminal device can determine whether the symbols in NCD-SSB can be transmitted uplink based on the pre-configured information.

[0024] In a possible implementation method, the symbols in the NCD-SSB include one or more of the following: a primary synchronization signal (PSS) symbol in the NCD-SSB, a PBCH symbol in the NCD-SSB, and a secondary synchronization signal (SSS) symbol in the NCD-SSB.

[0025] It can be understood that all or part of the symbols in NCD-SSB can be transmitted uplink.

[0026] In a second aspect, a communication method of the present application can be applied to a network device, or to a device in a network device (e.g., a chip, or a chip system, or a circuit), or a device that can be used in conjunction with a network device. The following description is based on the application to a network device as an example. The method may include: sending indication information, wherein the indication information is used by a terminal device to determine whether SSB symbols in all SSB burst sets within the first time period can be uplinked.

[0027] It can be seen that the present application can enable the terminal device to determine whether the SSB symbols in all SSB burst sets within the first time period can be transmitted uplink through indication information. Different from the prior art, which defines which specific SSB symbols in an SSB burst set can be used for uplink transmission, the impact on the initial access terminal device is not considered (on the same SSB burst set, the uplink transmission of the terminal device that has been accessed will interfere with the reception of SSB by the initial access terminal device). In an embodiment of the present application, a time period (such as a first time period) can be defined, and multiple SSB burst sets are covered in this time period. In units of SSB burst sets, it is determined whether the SSB symbols in all SSB burst sets in the time period can be transmitted uplink, wherein at least one SSB symbol in the SSB burst set in the first time period is not used for uplink transmission. It can be ensured that at least one SSB in the SSB burst set is not used for uplink transmission of other terminal devices but for detection of the SSB of the initial access terminal device within the time period, so as not to be interfered with by the uplink transmission, and the performance of the initial access is guaranteed to reduce the interference caused by uplink transmission on the SSB symbol. Therefore, in an embodiment of the present application, the terminal device can clearly determine whether the SSB symbol (which can be understood as the uplink subband of the SSB symbol) can be uplink transmitted, thereby achieving the beneficial effect of reducing the interference caused by uplink transmission on the SSB symbol.

[0028] It should be understood that the executor of the second aspect may be a network device, and the specific content of the second aspect corresponds to the content of the first aspect. The corresponding features of the second aspect and the beneficial effects achieved may refer to the description of the first aspect. To avoid repetition, the detailed description is appropriately omitted here.

[0029] In a possible implementation, a time period of the SSB burst set is smaller than the first time period.

[0030] In a possible implementation, the first time period is the time period of a default SSB burst set configured for an initial access terminal device.

[0031] In a possible implementation, the indication information is used to indicate whether the SSB symbol of each SSB burst set within the first time period can be uplink transmitted.

[0032] In a possible implementation, the indication information indicates an index of a first SSB burst set, where the first SSB burst set is any SSB burst set among all SSB burst sets within the first time period.

[0033] In a possible implementation, the indication information is also used to indicate whether each SSB symbol in the SSB burst set capable of uplink transmission can be transmitted uplink.

[0034] In a possible implementation, the indication information is also used to indicate the index of the SSB symbol that can be used for uplink transmission in the SSB burst set that can be used for uplink transmission.

[0115]

Sub-band full-duplex

[0116] Sub-band full-duplex is a new duplex system that can perform uplink and downlink transmission at the same time. Compared with the existing time division duplex (TDD) system that focuses more on downlink transmission, it provides an opportunity to enhance uplink services. Figure 2 , Figure 2 Schematic diagram of a sub-band full-duplex provided in an embodiment of the present application. Figure 2As shown, the existence of sub-bands can be used to divide uplink and downlink transmission in the frequency domain, and frequency division can be used to reduce interference while ensuring that uplink and downlink transmission can be performed at the same time. For network equipment, frequency domain resources can be divided into different sub-bands, and downlink transmission and uplink reception can be performed on different sub-bands at the same time. For terminal equipment, half-duplex can still be supported, and at a certain point in time, downlink reception can only be performed on the downlink sub-band or uplink transmission can only be performed on the uplink sub-band.

[0117] As an important downlink signal, SSB enjoys a higher priority in transmission. Since the configuration of SSB and uplink subbands are both periodic, and since the two periods may be different, period overlap is inevitable, the uplink subband can be configured on the SSB symbol.

[0118] [SSB burst set period]

[0119] In the current protocol, the SSB beam is not an omnidirectional beam, but different beam directions can be distinguished by SSB index, see Figure 3 , Figure 3 Schematic diagram of a beam scanning provided by an embodiment of the present application. Figure 3 As shown, L SSBs can be scanned to cover the entire area, and these L SSBs can form an SSB burst set ( Figure 3 The length of an SSB burst set is half a frame (5 ms), and the position of the SSB symbol in an SSB burst set is fixed. At the same time, the transmission of the periodic SSB symbol is determined by setting the period of the SSB burst set.

[0120] The terminal device first searches for the SSB, then detects the management information base (MIB) information in the SSB, obtains the location of the remaining minimum system information (RMSI), and then obtains the RMSI information, including the period and power of the configured SSB burst set, and which SSB symbols in an SSB burst set are sent uplink. For the initial access terminal device, the default SSB burst set period is 20ms (2 frames).

[0121] The present application proposes a communication method, which will be described below through the following embodiments. In the various embodiments of the present application, if there is no special explanation and logical conflict, the terms and / or descriptions between different embodiments are consistent and can be referenced to each other, and the technical features in different embodiments can be combined to form a new embodiment according to their inherent logical relationship.

[0122] In the embodiment of the present application, a terminal device (such as the following Figure 4 Corresponding embodiments) or taking the terminal device and the network device as the execution subject of the interactive instruction as an example to illustrate the method (as shown below Figure 5 Corresponding embodiments). It can be understood that the present application does not limit the execution subject of the interactive schematic. For example, the terminal device may also be a chip, a chip system, or a processor that supports the terminal device to implement the method, or a logic module or software that can implement all or part of the terminal device functions; the network device may also be a chip, a chip system, or a processor that supports the network device to implement the method, or a logic module or software that can implement all or part of the network device functions. The embodiments of the present application are uniformly described here and will not be repeated later.

[0123] The following describes a communication method provided in an embodiment of the present application. Figure 4 , Figure 4 A flow chart of a communication method provided in an embodiment of the present application is shown as follows: Figure 4 As shown, the specific steps include the following: wherein step S402 is an optional step.

[0124] S401. The terminal device determines whether the SSB symbols in all SSB burst sets within the first time period can be uplink transmitted, or whether the symbols in the NCD-SSB can be uplink transmitted.

[0125] [Example 1]

[0126] The terminal device may determine whether the SSB symbols in all SSB burst sets within the first time period can be used for uplink transmission, and the time period of the SSB burst set may be less than the first time period. The first time period is the time period of the default SSB burst set configured for the initial access terminal device, for example, 20ms. In a possible implementation, at least one SSB symbol in the SSB burst set within the first time period is not used for uplink transmission.

[0127] See also Figure 5 , Figure 5 Schematic diagram of an interaction of a communication method provided in an embodiment of the present application. Figure 5 As shown, the specific steps may include the following steps.

[0128] S501: The network device sends instruction information to the terminal device. Correspondingly, the terminal device receives the instruction information from the network device.

[0129] In a first possible implementation manner, the indication information is used to indicate whether the SSB symbol of each SSB burst set within the first time period can be uplink transmitted.

[0130] The network device may indicate to the terminal device which SSB burst sets can be used for uplink transmission and which SSB burst sets cannot be used for uplink transmission in the first time period through indication information. For example, the first value of the indication information is used to indicate that uplink transmission can be performed, and the second value of the indication information is used to indicate that uplink transmission cannot be performed, and the first value is different from the second value. The value may be a binary value or a Boolean value, which is not limited in the embodiment of the present application.

[0131] In the existing standard, the default SSB burst set period of the initial access terminal device is 20ms. If the SSB burst set period is less than 20ms, then one 20ms will contain multiple SSB burst sets. In this case, the performance of the initial access can be guaranteed if the signal of one SSB burst set in the 20ms is not interfered by the uplink transmission.

[0132] When the first time period is 20ms and the period of the SSB burst set is set to 10ms or 5ms, the number of SSB burst sets within 20ms is 2 or 4. Figure 6 , Figure 6 Schematic diagram of an SSB burst set period provided by an embodiment of the present application. Figure 6 As shown, assuming that the first time period is 20ms, the period of the SSB burst set is 10ms, and there are 2 SSB burst sets in the first time period, this 20ms can start with the system frame number (SFN) being 0. The indication information can use 2 bits to respectively indicate whether the SSB symbols of the two SSB burst sets in the first time period can be uplinked, and one bit corresponds to all SSB symbols in an SSB burst set for unified indication. For example, a parameter is added to indicate the bitmap of all SSB burst sets in the first time period. When the SSB burst set can be uplinked and the indication that the SSB burst set cannot be uplinked is 0, the indication information of this parameter is 01 (or, when the SSB burst set can be uplinked and the indication that the SSB burst set cannot be uplinked is 0, the indication information of this parameter is 10), it can be indicated that the SSB symbol of the first SSB burst set in the first time period cannot be uplinked, and the SSB symbol of the second SSB burst set in the first time period can be uplinked. It can be understood that in this case, if the value in the indication information is greater than 1, it can be considered as an error indication (error case). Or considering that the minimum period of the SSB burst set is 5ms, there can be at most 4 SSB burst sets within 20ms, so at most 4 bits are used to indicate whether the SSB symbol of each SSB burst set within 20ms can be transmitted uplink. Therefore, no matter how many SSB burst sets there are in the first time period, 4 bits can be used uniformly for indication, for example Figure 6 As shown, there are 2 SSB burst sets in the first time period. The indication information can use the upper 2 bits and the lower 2 bits of the 4 bits to respectively indicate whether the SSB symbols of the 2 SSB burst sets in the first time period can be transmitted uplink. The indication method is similar and will not be repeated here.

[0133] See also Fig. 7A , Fig. 7A FIG. 1 is a schematic diagram of another SSB burst set period provided in an embodiment of the present application. Fig. 7A As shown, assuming that the first time period is 20ms, the period of the SSB burst set is 5ms, there are 4 SSB burst sets in the first time period, and the 20ms may start with a system frame number (SFN) of 0. The indication information may use 4 bits to respectively indicate whether the SSB symbols of the 4 SSB burst sets in the first time period can be uplink transmitted, and one bit corresponds to a SSB symbol in an SSB burst set for unified indication. For example, a new parameter is added to indicate the bitmap of all SSB burst sets in the first time period. When the indication that the SSB burst set can be transmitted uplink is 1, and the indication that the SSB burst set cannot be transmitted uplink is 0, the indication information of this parameter is 0110 (or, when the indication that the SSB burst set can be transmitted uplink is 0, and the indication that the SSB burst set cannot be transmitted uplink is 1, the indication information of this parameter is 1001), it can mean that the SSB symbol of the first SSB burst set in the first time period cannot be transmitted uplink, the SSB symbol of the second SSB burst set in the first time period can be transmitted uplink, the SSB symbol of the third SSB burst set in the first time period can be transmitted uplink, and the SSB symbol of the fourth SSB burst set in the first time period cannot be transmitted uplink. It can be understood that in this case, if the value in the indication information is greater than 1, it can be considered as an error indication (error case).

[0134] In a second possible implementation, the indication information indicates an index of a first SSB burst set, and the first SSB burst set is any SSB burst set among all SSB burst sets within the first time period.

[0135] Since the period of the SSB burst set is less than the first time period, a first time period will contain multiple SSB burst sets. In this case, the performance of initial access can be guaranteed if the signal of one SSB burst set in the first time period is not interfered by the uplink transmission. Therefore, the indication information can indicate the index of the first SSB burst set. The first SSB burst set can be an SSB burst set that cannot be uplinked in the first time period, or an SSB burst set that can be uplinked in the first time period. The indication information only needs to indicate the index of the SSB burst set, which can reduce the signaling overhead compared to indicating whether each SSB burst set can be uplinked.

[0136] For example, corresponding Figure 6 As shown, a new parameter SSBwithULtrans or SSBwithoutULtrans is added to indicate which SSB burst set can / cannot be transmitted uplink. When the parameter SSBwithULtrans is set to 1 or the parameter SSBwithoutULtrans is set to 0, the indication information may be 1, which may indicate that the SSB symbol of the SSB burst set with an index of "1" in the first time period can be transmitted uplink; or when the parameter SSBwithULtrans is set to 0 or the parameter SSBwithoutULtrans is set to 1, the indication information may be 0, which may indicate that the SSB symbol of the SSB burst set with an index of "0" in the first time period can be transmitted uplink.

[0137] For example, see Figure 7B and Figure 7C , Figure 7B and Figure 7C FIG. 1 is a schematic diagram of another SSB burst set period provided in an embodiment of the present application. Figure 7B As shown, when the parameter SSBwithULtrans is set to 0 or the parameter SSBwithoutULtrans is set to 1, the indication information may be 1, which may indicate that the SSB symbol of the SSB burst set with an index of "1" in the first time period cannot be transmitted uplink. Figure 7C As shown, when the parameter SSBwithULtrans is set to 1 or the parameter SSBwithoutULtrans is set to 0, the indication information may be 0, which may indicate that the SSB symbol of the SSB burst set with an index of "0" within the first time period may be uplink transmitted.

[0138] It can be understood that the indication information indicates that the SSB burst set can be uplink transmitted, which can be understood as all or part of the SSB symbols in the SSB burst set can be uplink transmitted. In the case where some SSB symbols in the SSB burst set can be uplink transmitted, further optionally, based on the above two possible implementations, the indication information can also be used to indicate whether each SSB symbol in the SSB burst set that can be uplink transmitted can be uplink transmitted, or the indication information is also used to indicate the index of the SSB symbol that can be uplink transmitted in the SSB burst set that can be uplink transmitted.

[0139] In one possible implementation, the indication information may include a first indication field and a second indication field, the first indication field being used to indicate which SSB burst sets in a first time period can be uplinked and which SSB burst sets cannot be uplinked, and the second indication field being used to indicate whether each SSB symbol in the SSB burst sets that can be uplinked can be uplinked or to indicate the index of the SSB symbol that can be uplinked in the SSB burst sets that can be uplinked. In another possible implementation, the first indication information may be used to indicate which SSB burst sets in a first time period can be uplinked and which SSB burst sets cannot be uplinked, and the second indication information may be used to indicate whether each SSB symbol in the SSB burst sets that can be uplinked can be uplinked or to indicate the index of the SSB symbol that can be uplinked in the SSB burst sets that can be uplinked. The first indication information and the second indication information may be sent simultaneously, or the first indication information may be sent first and then the second indication information. The first indication information and the second indication information can be carried in the same message (for example, both are carried in RRC or both are carried in DCI), or they can be carried in different messages (for example, the first indication information is carried in RRC and the second indication information is carried in DCI). The embodiment of the present application does not limit this.

[0140] If only the first indication field / first indication information exists, it may indicate that all SSB symbols in the SSB burst set capable of uplink transmission indicated by the first indication field or the first indication information can be uplink transmitted; if there is a second indication field / second indication information in addition to the first indication field / first indication information, it may indicate that all or part of the SSB symbols in the SSB burst set capable of uplink transmission indicated by the first indication field or the first indication information can be uplink transmitted.

[0141] The following is an exemplary description using an example in which the indication information includes a first indication field and a second indication field.

[0142] Exemplarily, in a first possible implementation, the first indication field in the indication information is used to indicate whether the SSB symbol of each SSB burst set in the first time period can be uplinked, and the second indication field is used to indicate whether each SSB symbol in the SSB burst set that can be uplinked can be uplinked or to indicate the index of the SSB symbol that can / cannot be uplinked in the SSB burst set that can be uplinked. The second indication field in the indication information can uniformly indicate whether each SSB symbol in all SSB burst sets that can be uplinked can be uplinked, that is, the second indication field can be one, and the indication for each SSB burst set that can be uplinked is the same; the second indication field in the indication information can also be multiple, that is, it can separately indicate whether each SSB symbol in each SSB burst set that can be uplinked can be uplinked.

[0143] like Figure 8 As shown, when the first indication field in the indication information is 01, it can indicate that the SSB symbol of the first SSB burst set in the first time period cannot be transmitted uplink, and the SSB symbol of the second SSB burst set in the first time period can be transmitted uplink. The second indication field in the indication information is 01101011, which can indicate that the first SSB symbol in the second SSB burst set in the first time period cannot be transmitted uplink, the second SSB symbol can be transmitted uplink, the third SSB symbol can be transmitted uplink, the fourth SSB symbol cannot be transmitted uplink, the fifth SSB symbol can be transmitted uplink, the sixth SSB symbol cannot be transmitted uplink, the seventh SSB symbol can be transmitted uplink, and the eighth SSB symbol can be transmitted uplink. Or as Fig. 9 As shown, when the parameter SSBwithULtrans is set to 1 or the parameter SSBwithoutULtrans is set to 0, the second indication field in the indication information is 1, which can indicate that the SSB symbol with an index of "1" in the second SSB burst set in the first time period can be uplink transmitted.

[0144] like Fig.10As shown, when the first indication field in the indication information is 0110, it can indicate that the SSB symbol of the first SSB burst set in the first time period cannot be transmitted uplink, the SSB symbols of the second and third SSB burst sets in the first time period can be transmitted uplink, and the SSB symbol of the fourth SSB burst set in the first time period cannot be transmitted uplink. The second indication field in the indication information is 10010100, which can indicate that the first, fourth, and sixth SSB symbols in the second and third SSB burst sets in the first time period can be transmitted uplink, and the second, third, fifth, seventh, and eighth SSB symbols cannot be transmitted uplink. Or as Fig.11 As shown, the second indication field in the indication information is 11110000 and 10010100, which can indicate that the 1st to 4th SSB symbols in the 2nd SSB burst set in the first time period can be uplink transmitted, and the 5th to 8th SSB symbols cannot be uplink transmitted, and the 1st, 4th, and 6th SSB symbols in the 3rd SSB burst set in the first time period can be uplink transmitted, and the 2nd, 3rd, 5th, 7th, and 8th SSB symbols cannot be uplink transmitted. Or as Fig.12 As shown, when the parameter SSBwithULtrans is set to 1 or the parameter SSBwithoutULtrans is set to 0, the second indication field in the indication information is 1, which can uniformly indicate that the SSB symbol with index "1" in the second and third SSB burst sets in the first time period can be uplink transmitted, and the SSB symbols with other indexes cannot be uplink transmitted, or the second indication field in the indication information can also be 11, which can respectively indicate that the SSB symbol with index "1" in the second and third SSB burst sets in the first time period can be uplink transmitted, and the SSB symbols with other indexes cannot be uplink transmitted.

[0145] Exemplarily, in the second possible implementation method, the first indication field in the indication information is used to indicate the index of the first SSB burst set, and the second indication field is used to indicate whether each SSB symbol in the SSB burst set capable of uplink transmission can be uplink transmitted, or to indicate the index of the SSB symbol that can / cannot be uplink transmitted in the SSB burst set capable of uplink transmission.

[0146] correspond Fig. 9As shown, when the parameter SSBwithULtrans is set to 1 or the parameter SSBwithoutULtrans is set to 0, the first indication field in the indication information is 1, which may indicate that the SSB symbol of the SSB burst set with an index of "1" in the first time period can be transmitted uplink. The second indication field in the indication information is 01000000, which may indicate that the 1st, 3rd to 8th SSB symbols in the 2nd SSB burst set in the first time period cannot be transmitted uplink, and the 2nd SSB symbol can be transmitted uplink. Or the second indication field in the indication information is 1, which may indicate that the SSB symbol with an index of "1" in the 2nd SSB burst set in the first time period can be transmitted uplink.

[0147] like Fig.13 As shown, when the parameter SSBwithULtrans is set to 0 or the parameter SSBwithoutULtrans is set to 1, the first indication field in the indication information is 1, which can indicate that the SSB symbol of the SSB burst set with index "1" in the first time period cannot be uplink transmitted, and the SSB symbols of the SSB burst sets with other indexes (indexes "0", "2", and "3") can be uplink transmitted. The second indication field in the indication information is 11110000, which can uniformly indicate that the 1st to 4th SSB symbols in the SSB burst sets with indexes "0", "2", and "3" in the first time period cannot be uplink transmitted, and the 5th to 8th SSB symbols can be uplink transmitted. Or as Fig.14 As shown, the second indication field in the indication information is 11110000, 10010100 and 10110110, which can respectively indicate that the 1st to 4th SSB symbols in the SSB burst set with index "0" in the first time period cannot be uplink transmitted, the 5th to 8th SSB symbols can be uplink transmitted, and the 1st, 4th and 6th SSB symbols in the burst set with index "2" in the first time period cannot be uplink transmitted, the 2nd, 3rd, 5th, 7th and 8th SSB symbols can be uplink transmitted, and the 1st, 3rd, 4th, 6th and 7th SSB symbols in the SSB burst set with index "3" in the first time period cannot be uplink transmitted, and the 2nd, 5th and 8th SSB symbols can be uplink transmitted. Or as Fig.15As shown, the second indication field in the indication information is 1, which can uniformly indicate that the SSB symbol with index "1" in the SSB burst sets with indexes "0", "2" and "3" in the first time period cannot be transmitted uplink, and the SSB symbols with other indexes can be transmitted uplink, or the second indication field in the indication information is 111, which can respectively indicate that the SSB symbol with index "1" in the SSB burst sets with indexes "0", "2" and "3" in the first time period cannot be transmitted uplink, and the SSB symbols with other indexes can be transmitted uplink.

[0148] like Fig.16 As shown, when the parameter SSBwithULtrans is set to 1 or the parameter SSBwithoutULtrans is set to 0, the first indication field in the indication information is 0, which means that the SSB symbol of the SSB burst set with index "0" in the first time period can be uplink transmitted, and the SSB symbols of the SSB burst sets with other indexes cannot be uplink transmitted. The second indication field in the indication information is 11110000, which means that the 1st to 4th SSB symbols in the SSB burst set with index "1" in the first time period can be uplink transmitted, and the 5th to 8th SSB symbols cannot be uplink transmitted. Or as Fig.17 As shown, the second indication field in the indication information is 1, which can indicate that the SSB symbol with index "1" in the SSB burst set with index "1" in the first time period can be transmitted uplink, and SSB symbols with other indexes cannot be transmitted uplink.

[0149] Optionally, the indication information may be carried by one of DCI, system information, and RRC message.

[0150] S502. The terminal device determines whether the SSB symbols in all SSB burst sets within the first time period can be uplink transmitted according to the indication information.

[0151] Corresponding to the first possible implementation in the above step S501, the indication information is used to indicate whether the SSB symbol of each SSB burst set in the first time period can be uplink transmitted. The terminal device can determine whether the SSB symbol of each SSB burst set in the first time period can be uplink transmitted according to the indication information.

[0152] For example, as mentioned above Figure 6 As shown, the indication information is 01, and the terminal device can determine according to the indication information that the SSB symbol of the first SSB burst set in the first time period cannot be transmitted uplink, and the SSB symbol of the second SSB burst set in the first time period can be transmitted uplink. Fig. 7AAs shown, the indication information is 0110. The terminal device can determine according to the indication information that the SSB symbol of the first SSB burst set in the first time period cannot be uplink transmitted, the SSB symbol of the second SSB burst set in the first time period can be uplink transmitted, the SSB symbol of the third SSB burst set in the first time period can be uplink transmitted, and the SSB symbol of the fourth SSB burst set in the first time period cannot be uplink transmitted.

[0153] Further optionally, the indication information may include a first indication field and a second indication field. The first indication field is used to indicate whether the SSB symbol of each SSB burst set within the first time period can be uplink transmitted, and the second indication field is used to indicate whether each SSB symbol in the SSB burst set that can be uplink transmitted can be uplink transmitted or to indicate the index of the SSB symbol that can be uplink transmitted in the SSB burst set that can / cannot be uplink transmitted.

[0154] For example, as mentioned above Figure 8 As shown, the first indication field in the indication information is 01, and the second indication field is 01101011. The terminal device can determine that the SSB symbol of the first SSB burst set in the first time period cannot be uplink transmitted, the SSB symbol of the second SSB burst set in the first time period can be uplink transmitted, and the first SSB symbol in the second SSB burst set in the first time period cannot be uplink transmitted, the second SSB symbol can be uplink transmitted, the third SSB symbol can be uplink transmitted, the fourth SSB symbol cannot be uplink transmitted, the fifth SSB symbol can be uplink transmitted, the sixth SSB symbol cannot be uplink transmitted, the seventh SSB symbol can be uplink transmitted, and the eighth SSB symbol can be uplink transmitted. Or when the parameter SSBwithULtrans is set to 1 or the parameter SSBwithoutULtrans is set to 0, the second indication field is 1, and the terminal device can determine that the SSB symbol with index "1" in the second SSB burst set in the first time period can be uplink transmitted, and SSB symbols with other indexes cannot be uplink transmitted.

[0155] For example, as mentioned above Fig.10As shown, the first indication field in the indication information is 0110, and the terminal device can determine that the SSB symbol of the first SSB burst set in the first time period cannot be uplink transmitted, the SSB symbols of the second and third SSB burst sets in the first time period can be uplink transmitted, and the SSB symbol of the fourth SSB burst set in the first time period cannot be uplink transmitted. The second indication field in the indication information is 10010100, and the terminal device can determine that the first, fourth, and sixth SSB symbols in the second and third SSB burst sets in the first time period can be uplink transmitted, and the second, third, fifth, seventh, and eighth SSB symbols cannot be uplink transmitted. Or as Fig.11 As shown, the second indication field is 11110000 and 10010100, and the terminal device can determine that the 1st to 4th SSB symbols in the 2nd SSB burst set in the first time period can be uplink transmitted, and the 5th to 8th SSB symbols cannot be uplink transmitted; and the 1st, 4th, and 6th SSB symbols in the 3rd SSB burst set in the first time period can be uplink transmitted, and the 2nd, 3rd, 5th, 7th, and 8th SSB symbols cannot be uplink transmitted. Or as Fig.12 As shown, when the parameter SSBwithULtrans is set to 1 or the parameter SSBwithoutULtrans is set to 0, the second indication field in the indication information is 1, and the terminal device can determine that the SSB symbol with index "1" in the second and third SSB burst sets in the first time period can be uplink transmitted, and the SSB symbols with other indexes cannot be uplink transmitted; the second indication field in the indication information can also be 11, and the terminal device can determine that the SSB symbol with index "1" in the second SSB burst set in the first time period can be uplink transmitted, and the SSB symbol with index "1" in the third SSB burst set in the first time period can be uplink transmitted, and the SSB symbol with index "1" in the third SSB burst set in the first time period can be uplink transmitted, and the SSB symbols with other indexes cannot be uplink transmitted.

[0156] Corresponding to the second possible implementation method in the above step S501, the indication information indicates the index of the first SSB burst set. The terminal device can determine that the SSB symbols in the first SSB burst set cannot be uplinked according to the index of the first SSB burst set, and that the SSB symbols in other SSB burst sets except the first SSB burst set in the first time period can be uplinked. Or the terminal device can determine that the SSB symbols in the first SSB burst set can be uplinked according to the index of the first SSB burst set, and that the SSB symbols in other SSB burst sets except the first SSB burst set in the first time period cannot be uplinked.

[0157] For example, as mentioned above Figure 6 As shown, when the parameter SSBwithULtrans is set to 1 or the parameter SSBwithoutULtrans is set to 0, the indication information is 1, and the terminal device can determine that the SSB symbol of the SSB burst set with an index of "1" in the first time period can be transmitted uplink. Figure 7B As shown, when the parameter SSBwithULtrans is set to 0 or the parameter SSBwithoutULtrans is set to 1, the indication information may be 1, and the terminal device may determine that the SSB symbol of the SSB burst set with an index of "1" in the first time period cannot be transmitted uplink. Figure 7C As shown, when the parameter SSBwithULtrans is set to 1 or the parameter SSBwithoutULtrans is set to 0, the indication information is 1, and the terminal device can determine that the SSB symbol of the SSB burst set with an index of "1" within the first time period can be uplink transmitted.

[0158] Further optionally, the indication information may include a first indication field and a second indication field. The first indication field is used to indicate the index of the first SSB burst set, and the second indication field is used to indicate whether each SSB symbol in the SSB burst set capable of uplink transmission can be uplinked or to indicate the index of the SSB symbol capable of uplink transmission in the SSB burst set capable of / incapable of uplink transmission.

[0159] For example, as mentioned above Fig. 9 As shown, when the parameter SSBwithULtrans is set to 1 or the parameter SSBwithoutULtrans is set to 0, the first indication field in the indication information is 1, and the second indication field is 01000000. The terminal device can determine that the 1st, 3rd to 8th SSB symbols in the SSB burst set with index "1" in the first time period cannot be uplink transmitted, and the 2nd SSB symbol can be uplink transmitted. Or the second indication field is 1, the terminal device can determine that the SSB symbol with index "1" in the second SSB burst set in the first time period can be uplink transmitted, and the SSB symbols with other indexes cannot be uplink transmitted.

[0160] For example, as mentioned above Fig.13As shown, when the parameter SSBwithULtrans is set to 0 or the parameter SSBwithoutULtrans is set to 1, the first indication field in the indication information is 1, and the second indication field is 11110000. The terminal device can determine that the SSB symbol of the SSB burst set with index "1" in the first time period cannot be uplink transmitted, and the SSB symbols of the SSB burst sets with other indexes (indexed as "0", "2", and "3") can be uplink transmitted, and the 1st to 4th SSB symbols in the SSB burst sets with indexed as "0", "2", and "3" in the first time period cannot be uplink transmitted, and the 5th to 8th SSB symbols can be uplink transmitted. Or as Fig.14 As shown, the second indication field is 11110000, 10010100 and 10110110, and the terminal device can determine that the 1st to 4th SSB symbols in the SSB burst set with index "0" in the first time period cannot be uplink transmitted, and the 5th to 8th SSB symbols can be uplink transmitted, and the 1st, 4th and 6th SSB symbols in the burst set with index "2" in the first time period cannot be uplink transmitted, and the 2nd, 3rd, 5th, 7th and 8th SSB symbols can be uplink transmitted, and the 1st, 3rd, 4th, 6th and 7th SSB symbols in the SSB burst set with index "3" in the first time period cannot be uplink transmitted, and the 2nd, 5th and 8th SSB symbols can be uplink transmitted. Or as Fig.15 As shown, the second indication field is 1 or 111, and the terminal device can determine that the SSB symbol with index "1" in the SSB burst set with indexes "0", "2" and "3" in the first time period cannot be transmitted uplink, and the SSB symbols with other indexes can be transmitted uplink.

[0161] For example, as mentioned above Fig.16 As shown, when the parameter SSBwithULtrans is set to 1 or the parameter SSBwithoutULtrans is set to 0, the first indication field in the indication information is 1, and the second indication field is 11110000. The terminal device can determine that the SSB symbol of the SSB burst set with index "1" in the first time period can be uplink transmitted, and the SSB symbols of the SSB burst sets with other indexes cannot be uplink transmitted, and the 1st to 4th SSB symbols in the SSB burst set with index "1" in the first time period can be uplink transmitted, and the 5th to 8th SSB symbols cannot be uplink transmitted. Or as Fig.17As shown, the second indication field in the indication information is 1, and the terminal device can determine that the SSB symbol with index "1" in the SSB burst set with index "1" in the first time period can be transmitted uplink, and SSB symbols with other indexes cannot be transmitted uplink.

[0162] [Example 2]

[0163] The terminal device can determine whether the symbols in the NCD-SSB can be transmitted uplink.

[0164] A possible implementation method is to configure whether the symbols in the NCD-SSB can be transmitted uplink when pre-configuring the configuration information of the NCD-SSB. In this way, the terminal device can determine whether the symbols in the NCD-SSB can be transmitted uplink according to the pre-configuration information of the NCD-SSB. The nonCellDefiningSSB shown in the NCD-SSB under BWP-DownlinkDedicated is configured independently for each terminal device. In the existing standard, the SSB symbols configured here will not be rate matched for other signals, that is, their priority is lower than that of CD-SSB.

[0165] The symbols in the NCD-SSB include one or more of the following: PSS symbols in the NCD-SSB, PBCH symbols in the NCD-SSB, and SSS symbols in the NCD-SSB. In other words, all or part of the symbols in the NCD-SSB can be used for uplink transmission.

[0166] See also Fig.18 , Fig.18 Schematic diagram of a NCD-SSB provided in the embodiment of the present application. Fig.18 As shown in (a), all symbols in NCD-SSB can be used for uplink transmission. Considering that NCD-SSB has a lower priority and NDC-SSB is UE-specific, the terminal devices do not know the location of NCD-SSB configured by other terminal devices. Therefore, all NCD-SSB symbols can be used for uplink transmission. Considering that some NCD-SSB signals have high reliability and can be correctly demodulated in the case of high noise or truncation, uplink transmission can be allowed on some NCD-SSB symbols, such as Fig.18 As shown in (b), uplink transmission can be performed on the PSS symbol, or as Fig.18 As shown in (c), uplink transmission can be performed on symbols including PBCH.

[0167] S402: The terminal device performs uplink transmission.

[0168] Optionally, after the terminal device determines whether the SSB symbols in all SSB burst sets in the first time period can be uplink transmitted, or whether the symbols in the NCD-SSB can be uplink transmitted, uplink transmission can be performed on the SSB symbols that can be uplink transmitted. It should be noted that the uplink transmission performed by the terminal device on the SSB symbol can also be understood as the uplink transmission performed by the terminal device on the uplink subband configured by the SSB symbol.

[0169] It can be seen that, unlike the prior art which defines which specific SSB symbols in an SSB burst set can be used for uplink transmission, the impact on the initial access terminal device is not considered (on the same SSB burst set, the uplink transmission of the terminal device that has been accessed will interfere with the reception of SSB by the initial access terminal device). In an embodiment of the present application, a time period (such as a first time period) can be defined, and multiple SSB burst sets are covered in this time period. Taking the SSB burst set as a unit, it is determined whether the SSB symbols in all SSB burst sets in the time period can be used for uplink transmission, wherein at least one SSB symbol in the SSB burst set in the first time period is not used for uplink transmission. It can be ensured that at least one SSB in the SSB burst set is not used for uplink transmission of other terminal devices but for detection of the SSB of the initial access terminal device within the time period, so as not to be interfered with by the uplink transmission, thereby ensuring the performance of the initial access and reducing the interference caused by uplink transmission on the SSB symbol. Alternatively, for a terminal device in a connected state, it is possible to determine whether the symbols in the NCD-SSB can be used for uplink transmission. Since the priority of the NCD-SSB is low and it will not be used for cell selection and reselection, etc., the consequences caused by interference caused by uplink transmission on the SSB symbol can be reduced. Therefore, in an embodiment of the present application, the terminal device can clarify whether the SSB symbol (which can be understood as the uplink subband of the SSB symbol) can be used for uplink transmission, thereby achieving the beneficial effect of reducing the interference caused by uplink transmission on the SSB symbol.
