[0002] The issue of QCL (Quasi CoLoacted) configuration involved in the tracking reference signal (TRS for idle UE) of the terminal equipment in the idle state is still under discussion. The configured beam of the tracking reference signal of the terminal equipment in the idle state may not be consistent with the narrow beam corresponding to a single SSB (Synchronization signal block). In other words, TRS for idle UE may be a wide beam configuration, that is, a beam set corresponding to multiple SSB indexes. However, the current signaling overhead for the QCL configuration of the tracking reference signal of the terminal equipment in the idle state is too large. Summary of the invention

[0015] In one implementation, the method further includes:

[0049] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application.

Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete manner.

[0051] It should be noted that the QCL (Quasi Co-Loacted) configuration issue involved in the tracking reference signal (TRS for idle UE) of the terminal device in the idle state is still under discussion. The configured beam of the tracking reference signal of the terminal device in the idle state may not be consistent with the narrow beam corresponding to a single SSB (Synchronization signal block). In other words, TRS for idle UE may be a wide beam configuration, that is, a beam set corresponding to multiple SSB indexes. However, the current signaling overhead for the QCL configuration of the tracking reference signal of the terminal device in the idle state is too large.

[0052] To this end, the present application proposes a quasi-co-site configuration method, a quasi-co-site QCL information determination method and a device thereof, which are applied to the 5G NR network system. By configuring the quasi-co-site QCL relationship between the tracking reference signal TRS and SSB according to the index of the SSB, signaling overhead can be saved, thereby saving device power and avoiding resource waste.

[0053] In order to better understand the quasi-co-location configuration method disclosed in the embodiment of the present application, the communication system used in the embodiment of the present application is first described below.

[0054] See also Figure 1 , Figure 1 The present invention provides a schematic diagram of the architecture of a communication system. The communication system may include but is not limited to a network device and a terminal device. Figure 1 The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of the present application. In actual applications, two or more network devices and two or more terminal devices may be included. Figure 1 The communication system shown includes a network device 101 and a terminal device 102 as an example.

[0055] It should be noted that the technical solutions of the embodiments of the present application can be applied to various communication systems, such as long term evolution (LTE) system, fifth generation (5G) mobile communication system, 5G new radio (NR) system, or other future new mobile communication systems.

[0056] The network device 101 in the embodiment of the present application is an entity for transmitting or receiving signals on the network side. For example, the network device 101 may be an evolved NodeB (eNB), a transmission point (TRP), a next generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system.

The network device provided in the embodiment of the present application may be composed of a centralized unit (CU) and a distributed unit (DU), wherein the CU may also be referred to as a control unit. The CU-DU structure may be used to split the protocol layer of the network device, such as the base station, and the functions of some protocol layers are placed in the CU for centralized control, and the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU.

[0057] The terminal device 102 in the embodiment of the present application is an entity for receiving or transmitting signals on the user side, such as a mobile phone. The terminal device can also be called a terminal device (terminal), a user equipment (UE), a mobile station (MS), a mobile terminal device (MT), etc. The terminal device can be a car with communication function, a smart car, a mobile phone, a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation safety (transportation safety), a wireless terminal device in smart city (smart city), a wireless terminal device in smart home (smart home), etc. The embodiment of the present application does not limit the specific technology and specific device form adopted by the terminal device.

[0058] It can be understood that the communication system described in the embodiment of the present application is for more clearly illustrating the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0059] The quasi-co-location configuration method, quasi-co-location QCL information determination method and device provided in the present application are described in detail below in conjunction with the accompanying drawings.

[0060] See also Figure 2 , Figure 2 is a flow chart of a quasi-co-location configuration method provided in an embodiment of the present application. It should be noted that the quasi-co-location configuration method in an embodiment of the present application can be applied to network devices. Figure 2 As shown, the quasi co-location configuration method may include but is not limited to the following steps.

[0061] Step 201, according to the index of the synchronization signal block SSB, configure the quasi-co-site QCL relationship between the tracking reference signal TRS and SSB; wherein the beam width corresponding to TRS is greater than or equal to the beam width corresponding to SSB.

[0062] In order to reduce the overhead, it is necessary to avoid the appearance of the always-on Cell Special Reference Signal (CRS) when accurately estimating the frequency offset, time offset, Doppler shift, Doppler spread, and delay spread of the system. Therefore, a new reference signal, the Tracking Reference Signal (TRS), is introduced. The receiving end can accurately estimate the channel parameters based on the TRS to improve the accuracy of demodulation.

[0063] The issue of QCL (Quasi Co-Loacted) configuration involved in the tracking reference signal (TRS for idle UE) of the terminal equipment in idle state is still under discussion. The beam configured by TRS for idle UE may not be consistent with the narrow beam corresponding to a single SSB. For example, the beam corresponding to a TRS may be an equivalent beam formed by combining multiple beams appearing in SSB.

[0064] In an embodiment of the present application, when the tracking reference signal (TRS for idle UE) of the terminal device in an idle state is configured with a wide beam, that is, the beam width of the TRS is greater than or equal to the beam width corresponding to the SSB, for example, when the beams appearing in multiple SSBs correspond to an equivalent beam of a TRS, the network device in an embodiment of the present application can configure the quasi-co-location QCL relationship between the tracking reference signal TRS and the SSB according to the index of the SSB, that is, it can tell the terminal device UE which of the many beams of the SSB each TRS corresponds to, thereby saving signaling overhead, thereby saving device power and avoiding waste of resources.

[0065] It should be noted that, for a beam corresponding to a TRS, in the prior art, when the network device configures the quasi-co-location QCL relationship between the TRS and the SSB, it indicates all SSB indexes corresponding to the TRS. For example, assuming that the index set of the SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, for a beam corresponding to a TRS, assuming that the beam corresponding to the TRS is composed of beams corresponding to index 0, index 1, index 2, and index 3, the network device in the prior art indicates that the beam beam corresponding to SSB index 0, SSB index 1, SSB index 2, and SSB index 3 corresponds to the beam of the TRS to configure the QCL relationship between the TRS and the SSB. It can be seen that in the prior art, when the network device is configured, SSB index 0, SSB index 1, SSB index 2, and SSB index 3 are all written in the signaling, which occupies signaling resources and makes the signaling overhead too large.

[0066] In order to further save signaling overhead, the embodiment of the present application can be configured using the start index and end index of the SSB. In one implementation, Figure 3 Flow chart of another quasi-co-location configuration method provided in an embodiment of the present application. It should be noted that the quasi-co-location configuration method in an embodiment of the present application can be applied to network devices. Figure 3 As shown, the quasi co-location configuration method of the embodiment of the present application may include but is not limited to the following steps.

[0067] Step 301, according to the index of the synchronization signal block SSB, configure the start index and end index of the SSB corresponding to the TRS; wherein the beam width corresponding to the TRS is greater than or equal to the beam width corresponding to the SSB.

[0068] For example, for a beam corresponding to a TRS, the network device of an embodiment of the present application may configure the starting index and ending index of the SSB corresponding to the TRS, so that the width of the TRS beam can be clearly configured through the starting index and ending index of the SSB. For example, assuming that the index set of SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, for a beam corresponding to a TRS, index 0 may be configured as the starting index and index 3 may be configured as the ending index, then the beams corresponding to SSB index 0, SSB index 1, SSB index 2, and SSB index 3 are combined to form the beam of the TRS, that is, the width of the corresponding TRS beam is clearly configured through SSB index 0, SSB index 1, SSB index 2, and SSB index 3.

[0069] In some embodiments of the present application, Figure 3 As shown, the quasi co-location configuration method may further include step 302. In step 302, the configured QCL relationship between the TRS and the SSB may be sent to the terminal device. That is, the network device may send the configured QCL relationship between the TRS and the SSB to the terminal device, so that the terminal device may determine the QCL reference signal of the TRS or the SSB according to the QCL relationship.

[0070] It should be noted that multiple TRS resources for idle UE may be configured, and multiple resources may be configured separately. In one implementation, TRS is configured for multiple resources, and for each TRS resource, the quasi-co-address QCL relationship between the TRS resource and the SSB may be configured according to the index of the synchronization signal block SSB. For example, taking the configuration method of using the start index and end index of the SSB to configure the QCL relationship between the TRS and the SSB as an example, for multiple TRS resource configurations, the start index and end index of the SSB corresponding to each TRS resource may be configured separately. For example, assuming that the index set of SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, and assuming that a first TRS resource and a second TRS resource are configured, index 0 can be configured as the SSB start index corresponding to the first TRS resource, index 3 can be configured as the SSB end index corresponding to the first TRS resource, index 4 can be configured as the SSB start index corresponding to the second TRS resource, and index 5 can be configured as the SSB end index corresponding to the second TRS resource. Then, the beam beam corresponding to SSB index 0, SSB index 1, SSB index 2, and SSB index 3 are combined to form the beam of the first TRS resource, that is, the width of the beam corresponding to the first TRS resource is explicitly configured through SSB index 0, SSB index 1, SSB index 2, and SSB index 3; the beam beam corresponding to SSB index 4 and SSB index 5 are combined to form the beam of the second TRS resource, that is, the width of the beam corresponding to the second TRS resource is explicitly configured through SSB index 4 and SSB index 5.

[0071] It can be seen that the network device of the embodiment of the present application configures the start index and end index of the SSB corresponding to the TRS, so that the width of the TRS beam can be clearly configured through the start index and end index of the SSB, which can reduce the index value written in the signaling while ensuring the relationship between TRS and SSB, thereby further saving signaling overhead, thereby further saving device power and avoiding waste of resources.

[0072] It should be noted that in the NR network, after the initial access of the terminal device, the network device will send the SSB index actually sent to the terminal device in the form of a bitmap. For the frequency range FR1, the maximum is 8 bits; but for the frequency range FR2, the maximum is 64 bitmaps. Therefore, for FR2, if the fullbitmap is used in the configuration of TRS for idle, the signaling overhead is too large; especially in the case where multiple (such as n) TRS resources may be configured in FR2, the signaling overhead will be 64*n. In order to further reduce the signaling overhead, a bitmap with a preset number of bits can be used to configure the quasi-co-location QCL relationship between TRS and SSB. In one implementation, Figure 4 Flow chart of another quasi co-location configuration method provided in the embodiment of the present application. It should be noted that the quasi co-location configuration method in the embodiment of the present application can be applied to network devices. Figure 4 As shown, the quasi co-location configuration method of the embodiment of the present application may include but is not limited to the following steps.

[0073] Step 401, according to the index of the synchronization signal block SSB, configure the quasi-co-address QCL relationship between TRS and SSB based on a bitmap of a preset number of bits; wherein the beam width corresponding to TRS is greater than or equal to the beam width corresponding to SSB.

[0074] In one implementation, the preset number may be 8. For example, when the tracking reference signal (TRS for idle UE) of the terminal device in an idle state is configured as a wide beam, that is, the beam width of the TRS is greater than or equal to the beam width corresponding to the SSB, for example, when the beams appearing in multiple SSBs correspond to an equivalent beam of a TRS, the quasi-co-address QCL relationship between the TRS and the SSB may be configured through a bitmap containing 8 bits. The value of each bit in the bitmap may be 0 or 1, and "1" represents the beam beam of the SSB with the corresponding index number. In this way, a string of 8-bit numbers may be used to know which SSB beam beams make up a TRS beam beam, thereby greatly saving signaling overhead, thereby further saving device power and avoiding resource waste. It should also be noted that the example of the bitmap consisting of 8 bits given in the embodiment of the present application is only an example for the convenience of technical personnel in the field to understand the present application scheme. That is to say, the number of bits in the bitmap involved in the embodiment of the present application may not be 8, for example, it may be less than 8, or greater than 8, which can be negotiated and stipulated according to the actual application situation, and the present application does not make any specific limitation on this.

[0075] In one implementation, for a terminal device receiving information in a frequency range FR1, a network device may configure the bit value of each bit in a bitmap according to an index of an SSB; wherein the bit in the bitmap is used to represent the index of the SSB, and the bit value of each bit in the bitmap is used to represent a quasi-co-site QCL relationship between the TRS and the SSB. For example, assuming that the bitmap consists of 8 bits, assuming that the index set of SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, for the beam corresponding to a TRS, assuming that the beam corresponding to the TRS is composed of beams corresponding to index 0, index 1, index 2, and index 3, then the network device can configure the bit value of the corresponding bit in the bitmap to 1 according to index 0, index 1, index 2, and index 3, and configure the bit values ​​corresponding to other bits in the bitmap to 0. For example, the bitmap consisting of 8 bits can be configured as "11110000", wherein the first to fourth bits in the bitmap correspond to index 0, index 1, index 2, and index 3, respectively, and the bit values ​​of the first to fourth bits are 1, indicating that the beams corresponding to index 0, index 1, index 2, and index 3 correspond to the beam of the TRS, thereby realizing the configuration of the QCL relationship between the TRS and SSB.

[0076] It should be noted that multiple TRS resources for idle UE may be configured, and multiple resources may be configured separately. In one implementation, TRS is configured for multiple resources, and for each TRS resource, the network device configures the quasi-co-address QCL relationship between the TRS resource and the SSB according to the index of the synchronization signal block SSB. Optionally, taking the configuration method of using a bitmap with a preset number of bits to configure the QCL relationship between TRS and SSB as an example, for multiple TRS resource configurations, for the terminal device receiving information on the frequency range FR1, the network device can configure the bit value of each bit in different bitmaps according to the index of the SSB. For example, assuming that the bitmap consists of 8 bits, assuming that the index set of SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, assuming that a first TRS resource and a second TRS resource are configured, the beam corresponding to the first TRS resource is composed of beams corresponding to index 0, index 1, index 2, and index 3, and the beam corresponding to the second TRS resource is composed of beams corresponding to index 4, index 5, and index 6, then the network device can configure the first bitmap corresponding to the first TRS resource according to index 0, index 1, index 2, and index 3, the bit value on the corresponding bit in the first bitmap is configured to 1, and the bit values ​​corresponding to other bits in the first bitmap are configured to 0. For example, the first bitmap consisting of 8 bits can be configured as "11110000", wherein the first to fourth bits in the first bitmap are respectively Corresponding to index 0, index 1, index 2, and index 3, the bit values ​​from the first to the fourth bits are 1, indicating that the beam beam corresponding to index 0, index 1, index 2, and index 3 corresponds to the beam of the TRS; the network device can configure the second bitmap corresponding to the second TRS resource according to index 4, index 5, and index 6, and the bit values ​​on the corresponding bits in the second bitmap are configured to 1, and the bit values ​​corresponding to other bits in the second bitmap are configured to 0. For example, the second bitmap consisting of 8 bits can be configured as "00001110", wherein the fifth to the seventh bits in the second bitmap correspond to index 4, index 5, and index 6, respectively, and the bit values ​​from the fifth to the seventh bits are 1, indicating that the beam beam corresponding to index 4, index 5, and index 6 corresponds to the beam of the TRS, thereby realizing the configuration of the QCL relationship between different TRS resources and SSB.

[0077] In one implementation, for a terminal device receiving information in a frequency range FR2, a network device may divide an index set of SSBs into a preset number of combinations; and configure a bit value of each bit in a bitmap; wherein each bit in the bitmap is used to represent an index of an SSB in a corresponding combination, and a bit value of each bit in the bitmap is used to represent a quasi-co-location QCL relationship between a TRS and an SSB.

[0078] Optionally, for the terminal device to receive information in the frequency range FR2, the network device can divide the index set of SSB into 8 groups, and configure the bit value of each bit in the bitmap containing 8 bits, wherein each bit in the bitmap is used to represent the index of the SSB in the corresponding group, and the bit value of each bit in the bitmap is used to represent the quasi-co-location QCL relationship between TRS and SSB.

[0079] For example, for a terminal device receiving information in a frequency range FR2, assuming that the bitmap consists of 8 bits, and assuming that the index set of the SSB includes 64 indexes, namely, index 0, index 1, index 2, ..., index 62, and index 63, the network device may divide the index set of the SSB into 8 combinations, wherein the first combination includes indexes 0 to 7, the second combination includes indexes 8 to 15, the third combination includes indexes 16 to 23, the fourth combination includes indexes 24 to 31, the fifth combination includes indexes 32 to 39, the sixth combination includes indexes 40 to 47, the seventh combination includes indexes 48 to 55, and the eighth combination includes indexes 56 to 63. For a beam corresponding to a TRS, assuming that the beam corresponding to the TRS is composed of beams corresponding to indexes 24 to 31, the network device can configure the bit value on the corresponding bit in the bitmap to 1, and the bit values ​​corresponding to other bits in the bitmap to 0 according to the relationship between indexes 24 to 31 and the corresponding combinations. For example, the bitmap composed of 8 bits can be configured as "00010000", wherein the fourth bit in the bitmap corresponds to the fourth combination, and the fourth combination includes indexes 24 to 31. The bit value on the fourth bit is 1, indicating that the beam beam corresponding to indexes 24 to 31 corresponds to the beam of the TRS, thereby realizing the configuration of the QCL relationship between the TRS and the SSB. It can be seen that by grouping the index set of the SSB and using the bitmap to indicate which groups correspond to the beam beam in the beam of the TRS, the signaling overhead can be greatly reduced, thereby further saving device power and avoiding resource waste.

[0080] It should be noted that multiple TRS resources for idle UE may be configured, and multiple resources may be configured separately. In one implementation, TRS is configured for multiple resources, and for each TRS resource, the network device configures the quasi-co-address QCL relationship between the TRS resource and the SSB according to the index of the synchronization signal block SSB. Optionally, taking the configuration method of using a bitmap with a preset number of bits to configure the QCL relationship between TRS and SSB as an example, for multiple TRS resource configurations, for the terminal device to receive information in the frequency range FR2, the network device can configure the bit value of each bit in different bitmaps according to the index of the SSB. For example, for a terminal device receiving information in a frequency range FR2, assuming that the bitmap consists of 8 bits, and assuming that the index set of the SSB includes 64 indexes, namely, index 0, index 1, index 2, ..., index 62, and index 63, the network device may divide the index set of the SSB into 8 combinations, wherein the first combination includes indexes 0 to 7, the second combination includes indexes 8 to 15, the third combination includes indexes 16 to 23, the fourth combination includes indexes 24 to 31, the fifth combination includes indexes 32 to 39, the sixth combination includes indexes 40 to 47, the seventh combination includes indexes 48 to 55, and the eighth combination includes indexes 56 to 63. Assuming that the first TRS resource and the second TRS resource are configured, the beam corresponding to the first TRS resource is composed of beams corresponding to indexes 24 to 31, and the beam corresponding to the second TRS resource is composed of beams corresponding to indexes 40 to 47. The network device can configure the bit value of the corresponding bit in the first bitmap to 1, and the bit values ​​corresponding to other bits in the first bitmap to 0 according to the relationship between indexes 24 to 31 and the corresponding combinations. For example, the first bitmap composed of 8 bits can be configured as "00010000", wherein the fourth bit in the first bitmap corresponds to the fourth combination, which includes indexes 24 to 31, and the bit value of the fourth bit is 1, indicating that the beam beam corresponding to indexes 24 to 31 corresponds to the beam of the first TRS. The network device can configure the bit value of the corresponding bit in the second bitmap to 1 and the bit value corresponding to other bits in the second bitmap to 0 according to the relationship between index 40 to index 47 and the corresponding combination. For example, the second bitmap consisting of 8 bits can be configured as "00000100", wherein the sixth bit in the second bitmap corresponds to the sixth combination, which includes index 40 to index 47, and the bit value of the sixth bit is 1, indicating that the beam corresponding to index 40 to index 47 corresponds to the beam of the second TRS, thereby realizing the configuration of the QCL relationship between different TRS and SSB.It can be seen that by grouping the index sets of SSB and using a bitmap to indicate which groups correspond to beams in the beam of the TRS, the signaling overhead can be greatly reduced, thereby further saving device power and avoiding resource waste.

[0081] It should also be noted that the grouping method of the SSB index set in the embodiment of the present application is only an example description given to facilitate the understanding of the present solution by those skilled in the art. That is to say, the grouping method can also be specified based on prior negotiation. As a possible implementation method, the SSB index set can be divided into 8 groups, and the number of indexes in each group can be the same or different. The present application does not make any specific limitation on this.

[0082] In some embodiments according to the present application, Figure 4 As shown, the quasi co-location configuration method may further include step 402. In step 402, the configured QCL relationship between the TRS and the SSB may be sent to the terminal device. That is, the network device may send the configured QCL relationship between the TRS and the SSB to the terminal device, so that the terminal device may determine the QCL reference signal of the TRS or the SSB according to the QCL relationship.

[0083] By implementing the embodiments of the present application, a string of 8-bit numbers can be used to know which SSB beams constitute a TRS beam, thereby greatly saving signaling overhead, thereby further saving device power and avoiding resource waste.

[0084] It can be understood that the above embodiment describes the implementation of the quasi co-location configuration method of the embodiment of the present application from the network device side. The embodiment of the present application also proposes a quasi co-location QCL information determination method, and the implementation of the quasi co-location QCL information determination method will be described from the terminal device side. Figure 5 , Figure 5 is a flow chart of a method for determining quasi co-location QCL information provided by an embodiment of the present application. It should be noted that the method for determining quasi co-location QCL information in an embodiment of the present application can be applied to a terminal device. Figure 5 As shown, the quasi co-site QCL information determination method may include but is not limited to the following steps.

[0085] Step 501, receiving the quasi-co-site QCL relationship between the tracking reference signal TRS and the synchronization signal block SSB configured by the network device.

[0086] In this embodiment of the present application, the beam width corresponding to the TRS is greater than or equal to the beam width corresponding to the SSB.

[0087] Optionally, when the tracking reference signal (TRS for idle UE) of the terminal device in the idle state is configured with a wide beam, that is, the beam width of the TRS is greater than or equal to the beam width corresponding to the SSB, for example, when the beams appearing in multiple SSBs correspond to an equivalent beam of a TRS, the network device can configure a quasi-co-site QCL relationship between the tracking reference signal TRS and the SSB according to the index of the synchronization signal block SSB.

[0088] In order to further save signaling overhead, in one implementation, the network device can configure the start index and end index of the SSB corresponding to the TRS according to the index of the synchronization signal block SSB; wherein the beam width corresponding to the TRS is greater than or equal to the beam width corresponding to the SSB. For example, for a beam corresponding to a TRS, the network device of an embodiment of the present application can configure the start index and end index of the SSB corresponding to the TRS, so that the width of the TRS beam can be clearly configured through the start index and end index of the SSB. For example, assuming that the index set of SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, for a beam corresponding to a TRS, index 0 can be configured as the start index and index 3 as the end index, then the beam beam corresponding to SSB index 0, SSB index 1, SSB index 2, and SSB index 3 is combined to form the beam of the TRS, that is, the width of the corresponding TRS beam is clearly configured through SSB index 0, SSB index 1, SSB index 2, and SSB index 3.

[0089] In order to further save signaling overhead, in one implementation, the network device may configure the quasi-co-address QCL relationship between TRS and SSB based on a bitmap of a preset number of bits according to the index of the synchronization signal block SSB; wherein the beam width corresponding to TRS is greater than or equal to the beam width corresponding to SSB. Optionally, the preset number may be 8. For example, when the tracking reference signal (TRS for idle UE) of the terminal device in the idle state is configured as a wide beam, that is, the beam width for TRS is greater than or equal to the beam width corresponding to SSB, for example, when the beams appearing in multiple SSBs correspond to an equivalent beam representing a TRS, the network device may configure the quasi-co-address QCL relationship between TRS and SSB through a bitmap containing 8 bits. Among them, the value of each bit in the bitmap can be 0 or 1, and "1" represents the use of the SSB beam with the corresponding index number. In this way, a string of 8-bit numbers can be used to know which SSB beams make up a TRS beam, which can greatly save signaling overhead, thereby further saving device power and avoiding resource waste.

[0090] In one implementation, for a terminal device receiving information in a frequency range FR1, a network device may configure the bit value of each bit in a bitmap according to an index of an SSB; wherein the bit in the bitmap is used to represent the index of the SSB, and the bit value of each bit in the bitmap is used to represent a quasi-co-site QCL relationship between the TRS and the SSB. For example, assuming that the bitmap consists of 8 bits, assuming that the index set of SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, for the beam corresponding to a TRS, assuming that the beam corresponding to the TRS is composed of beams corresponding to index 0, index 1, index 2, and index 3, then the network device can configure the bit value of the corresponding bit in the bitmap to 1 according to index 0, index 1, index 2, and index 3, and configure the bit values ​​corresponding to other bits in the bitmap to 0. For example, the bitmap consisting of 8 bits can be configured as "11110000", wherein the first to fourth bits in the bitmap correspond to index 0, index 1, index 2, and index 3, respectively, and the bit values ​​of the first to fourth bits are 1, indicating that the beams corresponding to index 0, index 1, index 2, and index 3 correspond to the beam of the TRS, thereby realizing the configuration of the QCL relationship between the TRS and SSB.

[0091] In one implementation, for a terminal device receiving information in a frequency range FR2, a network device may divide an index set of SSBs into a preset number of combinations; and configure a bit value of each bit in a bitmap; wherein each bit in the bitmap is used to represent an index of an SSB in a corresponding combination, and a bit value of each bit in the bitmap is used to represent a quasi-co-location QCL relationship between a TRS and an SSB.

[0092] Optionally, for the terminal device to receive information in the frequency range FR2, the network device can divide the index set of SSB into 8 groups, and configure the bit value of each bit in the bitmap containing 8 bits, wherein each bit in the bitmap is used to represent the index of the SSB in the corresponding group, and the bit value of each bit in the bitmap is used to represent the quasi-co-location QCL relationship between TRS and SSB.

[0093] For example, for a terminal device receiving information in a frequency range FR2, assuming that the bitmap consists of 8 bits, and assuming that the index set of the SSB includes 64 indexes, namely, index 0, index 1, index 2, ..., index 62, and index 63, the network device may divide the index set of the SSB into 8 combinations, wherein the first combination includes indexes 0 to 7, the second combination includes indexes 8 to 15, the third combination includes indexes 16 to 23, the fourth combination includes indexes 24 to 31, the fifth combination includes indexes 32 to 39, the sixth combination includes indexes 40 to 47, the seventh combination includes indexes 48 to 55, and the eighth combination includes indexes 56 to 63. For a beam corresponding to a TRS, assuming that the beam corresponding to the TRS is composed of beams corresponding to indexes 24 to 31, the network device can configure the bit value on the corresponding bit in the bitmap to 1, and the bit values ​​corresponding to other bits in the bitmap to 0 according to the relationship between indexes 24 to 31 and the corresponding combinations. For example, the bitmap composed of 8 bits can be configured as "00010000", wherein the fourth bit in the bitmap corresponds to the fourth combination, and the fourth combination includes indexes 24 to 31. The bit value on the fourth bit is 1, indicating that the beam beam corresponding to indexes 24 to 31 corresponds to the beam of the TRS, thereby realizing the configuration of the QCL relationship between the TRS and the SSB. It can be seen that by grouping the index set of the SSB and using the bitmap to indicate which groups correspond to the beam beam in the beam of the TRS, the signaling overhead can be greatly reduced, thereby further saving device power and avoiding resource waste.

[0094] Step 502: Determine the QCL reference signal of TRS or SSB according to the QCL relationship.

[0095] By implementing the embodiments of the present application, when the tracking reference signal (TRS for idleUE) of the terminal device in the idle state is configured with a wide beam, that is, the beam width of the TRS is greater than or equal to the beam width corresponding to the SSB, the network device configures the quasi-co-site QCL relationship between the tracking reference signal TRS and the SSB according to the index of the SSB, which can save signaling overhead, thereby saving device power and avoiding waste of resources.
