It can be understood that the communication system described in the embodiment of the present application is to illustrate the technical solution of the embodiment of the present application more clearly, and does not constitute a limitation to the technical solution provided in the embodiment of the present application. With the evolution of the system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

The quasi-co-location configuration method, the quasi-co-location QCL information determination method and the device thereof provided by the present application will be described in detail below with reference to the accompanying drawings.

Please refer to FIG. 2 . FIG. 2 is a flowchart of a quasi-co-location configuration method provided by an 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. As shown in FIG. 2 , the quasi-co-location configuration method may include but not limited to the following steps.

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

When accurately estimating the frequency offset, time offset, Doppler frequency shift, Doppler spread, and delay spread of the system, in order to reduce overhead, it is necessary to avoid the continuous (always on) cell-specific reference signal ( With the emergence of Cell Special Reference Signal (CRS), a new reference signal, the tracking reference signal TRS, is introduced. The receiving end can accurately estimate channel parameters according to the TRS and improve the accuracy of demodulation.

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

In the embodiment of the present application, in the case where the TRS for idle UE of the terminal device is configured with a wide beam, that is, the beam width for the TRS is greater than or equal to the beam width corresponding to the SSB, for example, when When the beams appearing in multiple SSBs correspond to the equivalent beams of a TRS, the network device in the embodiment of the present application can configure the quasi-co-located QCL relationship between the tracking reference signal TRS and the SSB according to the index of the SSB, that is, it can tell For the terminal equipment UE, each TRS corresponds to which of the many beams of the SSB, so as to save signaling overhead, thereby saving equipment power and avoiding waste of resources.

It should be noted that, for a beam corresponding to a TRS, in the prior art, when a network device configures a quasi-co-located QCL relationship between a TRS and an SSB, it points out all SSB indexes corresponding to the TRS. 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, it is assumed that the beam corresponding to the TRS is composed of index 0, The beam composition corresponding to index 1, index 2, and index 3. In the prior art, the network device indicates that the beam corresponding to SSB index 0, SSB index 1, SSB index 2, and SSB index 3 corresponds to the beam of the TRS, so as to configure the TRS The QCL relationship with 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, occupying the signaling resources, making the signaling overhead too large.

In order to further save signaling overhead, this embodiment of the present application may use the start index and end index of the SSB for configuration. In an implementation manner, FIG. 3 is a flowchart 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 the embodiment of the present application can be applied to network devices. As shown in FIG. 3 , the quasi-co-location configuration method in this embodiment of the present application may include but not limited to the following steps.

Step 301, configure the start index and end index of the SSB corresponding to the TRS according to the SSB index of the synchronization signal block; 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 in the embodiment of the present application can configure the start index and end index of the SSB corresponding to the TRS, so that the beam can be clearly configured through the start index and end index of the SSB. The width of the TRS beam. 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, index 0 can be configured as the starting index for a beam corresponding to a TRS, and index 3 as the end index, 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, through SSB index 0, SSB index 1, SSB index 2 and SSB index 3 The width of the corresponding TRS beam is explicitly configured.

In some embodiments of the present application, as shown in FIG. 3 , the quasi-co-location configuration method may further include step 302 . Wherein, step 302: the configured QCL relationship between the TRS and the SSB may be sent to the terminal device. That is to say, the network device can send the configured QCL relationship between the TRS and SSB to the terminal device, so that the terminal device can determine the QCL reference signal of the TRS or SSB according to the QCL relationship.

It should be noted that multiple TRS resources for idleUE may be configured, and multiple resources may be configured separately. In one implementation manner, the TRS is configured as multiple resources, and for each TRS resource, the quasi-co-location QCL relationship between the TRS resource and the SSB can be configured according to the index of the synchronization signal block SSB. For example, taking the configuration mode of using the start index and end index of SSB to configure the QCL relationship between TRS and SSB as an example, for multiple TRS resource configurations, the SSB corresponding to each TRS resource can be configured separately start index and end index. 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, assuming that the first TRS resource and the second TRS resource are configured, index 0 can be configured As the SSB start index corresponding to the first TRS resource, index 3 is used as the SSB end index corresponding to the first TRS resource, configuration index 4 is used as the SSB start index corresponding to the second TRS resource, and index 5 is used as the second TRS resource The SSB end index corresponding to the resource, 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 first TRS resource, that is, through SSB index 0, SSB index 1, SSB index 2 and SSB index 3 clearly configure the width of the beam corresponding to the first TRS resource; the beam beams corresponding to SSB index 4 and SSB index 5 are combined to form the beam of the second TRS resource, that is, explicitly configured by SSB index 4 and SSB index 5 corresponds to the width of the second TRS resource beam.

It can be seen that, by configuring the start index and end index of the SSB corresponding to the TRS, the network device in the embodiment of the present application can clearly configure the width of the TRS beam through the start index and end index of the SSB, which can make While the index value written in the signaling is reduced, the relationship between the TRS and the SSB can also be guaranteed, so that the signaling overhead can be further saved, thereby further saving the power of the device and avoiding resource waste.

It should be noted that in the NR network, after the initial access of the terminal device, the network device will send the actually sent SSB index 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 full bitmap is used in the configuration of TRS for idle, the signaling overhead is too large; especially in the case of 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 the TRS and the SSB. In an implementation manner, FIG. 4 is a flowchart 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 the embodiment of the present application can be applied to network devices. As shown in FIG. 4 , the quasi-co-location configuration method in this embodiment of the present application may include but not limited to the following steps.

Step 401, according to the index of the synchronization signal block SSB, configure the quasi-co-located QCL relationship between the TRS and the SSB based on a preset number of bitmaps; wherein, the beamwidth corresponding to the TRS is greater than or equal to the beamwidth corresponding to the SSB.

In an implementation manner, the preset number may be eight. For example, when the tracking reference signal (TRS for idle UE) of the terminal equipment in the idle state is configured with a wide beam, that is, the beam width for the TRS is greater than or equal to the beam width corresponding to the SSB, for example, when multiple SSBs appear When the beam corresponds to an equivalent beam of a TRS, the quasi-co-location QCL relationship between the TRS and the SSB can be configured through a bitmap containing 8 bits. Among them, the value of each bit (bit) in the bitmap can be 0 or 1, and "1" represents the beam beam of the SSB corresponding to the index number, so that a TRS beam can be known through a series of 8-digit numbers The beam is composed of several SSB beams, which can greatly save 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 this application is only an example for the convenience of those skilled in the art to understand the solution of this application, that is to say, this application The number of bits in the bitmap involved in the embodiment may not be 8, for example, may be less than 8, or may be greater than 8, which can be negotiated and stipulated according to the actual application situation, and this application does not specify this limited.

In one implementation, for the terminal device to receive information on the frequency range FR1, the network device can configure the bit value of each bit in the bitmap according to the index of the SSB; wherein, the bits in the bitmap are used to represent The index of the SSB, the bit value of each bit in the bitmap is used to represent the quasi-co-located QCL relationship between the TRS and the SSB. For example, assuming that the bitmap consists of 8 bits, 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 can place the corresponding bit in the bitmap according to index 0, index 1, index 2, and index 3 The bit value of the bitmap is configured as 1, and the bit values corresponding to other bits in the bitmap are configured as 0. For example, the bitmap composed of 8 bits can be configured as "11110000", where the first bit in the bitmap to The fourth bit corresponds 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 beam corresponding to index 0, index 1, index 2, and index 3 corresponds to the TRS beam, thereby realizing the configuration of the QCL relationship between the TRS and the SSB.

It should be noted that multiple TRS resources for idleUE may be configured, and multiple resources may be configured separately. In one implementation, the TRS is configured with multiple resources, and for each TRS resource, the network device configures the quasi-co-location QCL relationship between the TRS resource and the SSB according to the index of the synchronization signal block SSB. Optionally, taking the configuration method as an example of configuring the QCL relationship between the TRS and the SSB using a bitmap with a preset number of bits, for multiple TRS resource configurations, for the terminal device to receive information on the frequency range FR1, the network device can According to the index of the SSB, the bit value of each bit in different bitmaps is respectively configured. 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 there is a first TRS resource and The second TRS resource is configured. The beam corresponding to the first TRS resource is composed of beams corresponding to index 0, index 1, index 2, and index 3. The beam corresponding to the second TRS resource is composed of index 4, index 5, and index 6. beam composition, 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, and the bit value of the corresponding bit in the first bitmap is configured as 1. The bit values corresponding to other bits in the first bitmap are configured as 0. For example, the first bitmap composed of 8 bits can be configured as "11110000", where the first bit in the first bitmap The first to fourth bits 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 TRS beam; 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 value of the corresponding bit in the second bitmap is configured as 1, and the second bitmap The bit values corresponding to other bits in the two-bit map are configured as 0, for example, the second bit map composed of 8 bits can be configured as "00001110", wherein the fifth to seventh bits in the second bit map Corresponding to index 4, index 5, and index 6 respectively, the bit values of the fifth to seventh bits are 1, indicating that the beam corresponding to index 4, index 5, and index 6 corresponds to the beam of the TRS, thus realizing different TRS resources Configuration of QCL relationship with SSB.

In one implementation, for the terminal device to receive information on the frequency range FR2, the network device can divide the SSB index set into a preset number of combinations; configure the bit value of each bit in the bitmap; wherein, the bitmap Each bit in is used to indicate the index of the SSB in the corresponding combination, and the bit value of each bit in the bitmap is used to indicate the quasi-co-located QCL relationship between the TRS and the SSB.

Optionally, for the terminal device to receive information on the frequency range FR2, the network device may divide the SSB index set into 8 groups, and configure the bit value of each bit in the 8-bit bitmap, where , each bit in the bitmap is used to indicate the index of the SSB in the corresponding combination, and the bit value of each bit in the bitmap is used to indicate the quasi-co-located QCL relationship between the TRS and the SSB.

For example, for a terminal device to receive information on the frequency range FR2, it is assumed that the bitmap consists of 8 bits, and the index set of the SSB includes index 0, index 1, index 2, ..., index 62, index 63 which are 64 The network device can divide the index set of the SSB into 8 combinations, wherein the first combination includes index 0 to index 7, the second combination includes index 8 to index 15, and the third combination includes index 16-index 23, the fourth combination includes index 24-index 31, the fifth combination includes index 32-index 39, the sixth combination includes index 40-index 47, and the seventh combination Index 48 to index 55 are included in the eighth combination, and index 56 to index 63 are included in the eighth combination. For a beam corresponding to a TRS, assuming that the beam corresponding to the TRS is composed of the beams corresponding to the index 24~index 31, the network device can according to the relationship between the index 24~index 31 and the corresponding combination, the The bit value on the corresponding bit is configured as 1, and the bit value corresponding to other bits in the bitmap is configured as 0. For example, the bitmap composed of 8 bits can be configured as "00010000", where the bitmap No. The four bits correspond to the fourth combination, the fourth combination includes index 24 to index 31, and the bit value on the fourth bit is 1, indicating that the beam beam corresponding to index 24 to index 31 corresponds to the beam of the TRS, so as to realize configuration of the QCL relationship between the TRS and the SSB. It can be seen that by grouping the index sets of SSBs and using bitmaps to indicate which beams corresponding to the groups are in the beams of the TRS, signaling overhead can be greatly reduced, thereby further saving device power and avoiding waste of resources.

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

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 for the convenience of those skilled in the art to understand the solution, that is to say, it can also be based on pre-negotiated The grouping method is specified. As a possible implementation method, the SSB index sets can be grouped into 8 groups, and the number of indexes in each group can be the same or different, which is not specifically limited in this application.

In some embodiments according to the present application, as shown in FIG. 4 , the quasi-co-location configuration method may further include step 402 . Wherein, step 402: the configured QCL relationship between the TRS and the SSB may be sent to the terminal device. That is to say, the network device can send the configured QCL relationship between the TRS and SSB to the terminal device, so that the terminal device can determine the QCL reference signal of the TRS or SSB according to the QCL relationship.

In order to further save signaling overhead, in an implementation manner, the network device can configure the quasi-co-location QCL relationship between the TRS and the SSB based on the bitmap of a preset number of bits according to the index of the synchronization signal block SSB; wherein, the TRS The corresponding beam width is greater than or equal to the beam width corresponding to the SSB. Optionally, the preset number may be 8. For example, when the tracking reference signal (TRS for idle UE) of the terminal equipment in the idle state is configured with a wide beam, that is, the beam width for the TRS is greater than or equal to the beam width corresponding to the SSB, for example, when multiple SSBs appear When the beam corresponds to an equivalent beam of a TRS, the network device can configure the quasi-co-located QCL relationship between the TRS and the SSB through a bitmap containing 8 bits. Among them, the value of each bit (bit) in the bitmap can be 0 or 1, and "1" represents the beam beam of the SSB corresponding to the index number, so that a TRS beam can be known through a series of 8-digit numbers The beam is composed of several SSB beams, which can greatly save signaling overhead, thereby further saving device power and avoiding resource waste.
