Description

Method and device for radio resource management RRM measurement

This application claims the priority of a Chinese patent application filed on September 28, 2018 with the State Intellectual Property Office, application number 201811143545.2, and application name "Method and Device for Radio Resource Management RRM Measurement", the entire contents of which are incorporated herein by reference. In this application.

Technical field

The present application relates to the field of wireless communication technologies, and in particular, to a method and device for radio resource management RRM measurement.

Background technique

In a wireless communication system, in order to achieve optimal system performance and capacity, it is necessary to allocate and manage limited wireless resources. The allocation and management of radio resources are usually performed according to the measurement results of radio resource management (RRM) measurements. Therefore, RRM measurements need to be performed first. In the new radio (NR), each subcarrier can only be configured with a time configuration (SS-block-based RRM timing configuration (SMTC) based on RRM measurement based on a synchronization signal block). All terminal equipment in the cell served by the network equipment performs RRM measurement according to this SMTC. For the duration of an SMTC, for a terminal device, it needs to measure not only the SSB of the serving cell, but also the SSB of the neighboring cell.

The cycle and location of the SSBs of different neighboring cells may be different. Therefore, in order to measure the SSB of multiple neighboring cells, the terminal device needs to perform RRM measurement according to the minimum period of the SSB of the serving cell and all neighboring cells. It can be understood that the smaller the period of RRM measurement performed by the terminal device, the greater the power consumption.

Alternatively, the network device may also be a relay station, an access point, a vehicle-mounted device, a wearable device, etc. of a future communication system (for example, 5G).

In the embodiments of the present application, the synchronization signal block is also referred to as synchronization signal / physical broadcast channel (PBCH), which may include a PBCH, a primary synchronization signal (PSS), and a secondary synchronization signal (secondary). synchronization (SSS). The synchronization signal block can also be expressed as SSB or SS / PBCH block.

It should be understood that radio resource management (RRM) measurement is used for the functions of terminal equipment for power control, scheduling, cell selection, cell reselection, cell switching, radio link / connection detection, connection establishment and reconstruction. In new radio (new radio, NR), RRM uses SS / PBCH or channel state information reference signal (CSI-RS). When the terminal device is in an idle state, the RSB measurement is performed using the SSB.

Beams can also be referred to as spatial filters, spatial filters or spatial parameters. Beams can also be understood as space resources, and their energy transmission is directional.

According to the configuration or capability of the device, one device can use one or more of multiple different precoding vectors at the same time, that is, one beam or multiple beams can be formed at the same time.

Referring to FIG. 2, FIG. 2 is a schematic flowchart of an RRM measurement method 200 provided in the present application.

210. The network device sends association relationship information to the terminal device. The terminal device receives the association relationship information from the network device.

The association relationship information is used to indicate an association relationship between the SMTC and the SSB. Specifically, the association relationship information may indicate one or more of the following situations:

Association relationship between an SMTC and an SSB;

Association relationship between one SMTC and multiple SSBs;

Association relationship between multiple SMTCs and one SSB;

Association relationship between multiple SMTCs and multiple SSBs.

Optionally, when one SMTC is associated with multiple SSBs, the multiple SSBs may be continuous or discontinuous in time, which is not limited in this application.

In the embodiment of the present application, SMTC may also refer to SMTC window (SMTC window) or SMTC. Among them, SMTC window refers to the length of time that SMTC lasts.

Optionally, in this application, the association relationship may also be referred to as a mapping relationship or a corresponding relationship. Alternatively, one SMTC is associated with one SSB, and can also be expressed as one SMTC corresponding to one SSB, or expressed as one SMTC related to one SSB. An SSB is associated with an SMTC, which can indicate that the terminal equipment covered by the beam represented by the SSB can perform measurement only within the SMTC, or that the terminal equipment that receives the SSB can perform measurement within the SMTC.

Further, the SMTC is associated with the SSB, and the SMTC may be associated with the SSB index (SSB index).

Optionally, as an embodiment, the network device may further associate the period of the SMTC with the period of the SSB, which is not limited in this application. That is to say, in the embodiment of the present application, the network device associates the SMTC with the SSB. Specifically, it may associate a certain configuration parameter of the SMTC with a certain parameter of the SSB. The parameters of the SSB may include the period of the SSB, the SSB index, and the offset of the SSB. As described above, the configuration parameters of SMTC may include the period of SMTC, the length of SMTC, the frequency of neighboring cells, the SSB frequency of neighboring cells, the SSB frequency of cell definition of neighboring cells, the time offset of SMTC, One or more of the frequency points of the SMTC. In other words, the SMTC and the SSB have an associated relationship, which may include one or more configuration parameters of the SMTC and the SSB have an associated relationship.

In the embodiment of the present application, the network device uses the index association of the SMTC and the SSB as an example to describe the RRM measurement method 200 provided in the present application.

Optionally, as an embodiment, the association relationship information may be carried in any one or more of the following information, which is sent by the network device to the terminal device, and the information includes, but is not limited to, a physical broadcast channel (physical broadcast channel) (PBCH), remaining minimum system information (RMSI), system information block (SIB) 1, SIB2, SIB3, media access control-control element (MAC-CE) ) Signaling, downlink control information (downlink control information, DCI), radio resource control (radio resource control, RRC) signaling and system information.

Optionally, as another embodiment, the association relationship information may also be specified by a communication protocol standard. Alternatively, the association relationship information is predetermined by the network device and the terminal device. This application is not limited to this.

220. The terminal device determines a first SMTC associated with the first SSB according to the first SSB and the association relationship information.

Optionally, the first SSB may refer to an SSB corresponding to a beam in which the terminal device is located.

Optionally, the first SSB may also refer to an SSB currently used by the terminal device.

Optionally, the first SSB may also refer to an SSB currently received by the terminal device.

Optionally, there may be one or more SMTCs having an association relationship with the SSB corresponding to the beam in which the terminal device is located. That is, the first SMTC described in this application may be one or multiple.

It can be understood that the network device can serve multiple terminal devices, and different terminal devices may be on different beams transmitted by the network device. Therefore, the first SSB is different for different terminal devices. For each terminal device, the first SSB refers to the SSB corresponding to the beam in which it is located. Each terminal device determines an SMTC having an association relationship with the SSB corresponding to its own beam according to the SSB and association relationship information corresponding to its own beam.

For example, in the communication system shown in FIG. 5 below, the beam where the terminal device 102 is located is beam 1. Therefore, for the terminal device 102, the first SSB is the SSB corresponding to the beam 1. For another example, the beam where the terminal device 103 is located is beam 2. Therefore, for the terminal device 103, the first SSB is the SSB corresponding to the beam 2.

230. The terminal device performs RRM measurement according to the first SMTC.

In step 230, the terminal device performs RRM measurement according to the SMTC having an association relationship with the SSB corresponding to the beam in which the terminal device is located. The specific process of RRM measurement can refer to the prior art, and is not repeated here.

In the technical solution of the present application, the SSB and the SMTC are associated, so that each terminal device only needs to have an SMTC (ie, the first SMTC) having an association relationship according to the SSB (ie, the first SSB) corresponding to the beam in which it is located. The RRM measurement can be performed, and the period and position of the SSB corresponding to all beams transmitted by the network equipment in the serving cell need not be considered. Therefore, the terminal device can choose to perform RRM measurement according to the period of the first SMTC or an integer multiple of the period of the first SMTC, which can reduce the power consumption of the terminal device.

Further, the larger the integer multiple of the period of the first SMTC selected by the terminal device, the more the power consumption of the terminal device is reduced.

In the prior art, when the terminal device in the idle state performs RRM measurement, the configuration parameters (including the period of the SMTC) of the SMTC received by the terminal device from the network device for the RRM measurement are PerCell. That is to say, terminal equipment performs RRM measurement, and SMTC is cell-based. Therefore, for a terminal device, during the duration of the SMTC, it is necessary to measure not only the SSB of the local cell, but also the SSB of the neighboring cell. There may be multiple periods and locations of the SSBs of neighboring cells, and the conditions for the terminal equipment to perform RRM measurement are therefore different.

In order to facilitate understanding of the technical solution of the present application, the current RRM measurement process is briefly described below with reference to FIGS. 3 and 4.

Referring to FIG. 3, FIG. 3 is an example of a case where the terminal device performs RRM measurement according to the configuration parameters of the SMTC. As shown in FIG. 3, SC in FIG. 3 represents a serving cell (SC) where the terminal device is located. C1 and C2 respectively represent two neighboring cells of the SC. The horizontal axis in FIG. 3 represents time, where each cell represents 5 ms. In the scenario shown in FIG. 3, the period of the SSB of the SC is 20 ms, the period of the SSB of C1 is 10 ms, and the period of the SSB of C2 is 40 ms. In addition, the time-frequency positions of the SSBs of SC, C1, and C2 are shown in FIG. 3. When the terminal device performs RRM measurement, the minimum period of the SSB of SC, C1, and C2 can be selected as a period of RRM measurement, for example, a period of 10ms is used. In order to save power consumption, the terminal device can also select the maximum period of the SSB as a period of RRM measurement. That is, the terminal device has a period of 40 ms. As shown in FIG. 3, the terminal device performs an RRM measurement at the first 5ms, and performs a second RRM measurement at the 9th 5ms.

Referring to FIG. 4, FIG. 4 is an example of another case where the terminal device performs RRM measurement according to the configuration parameters of the SMTC. In FIG. 4, the period of the SSB of the SC is 20 ms, the period of the SSB of C1 is 10 ms, and the period of the SSB of C2 is 40 ms. At the time-frequency positions of SC, C1, and C2 shown in FIG. 4, the terminal device must select the minimum period of the SSB of SC, C1, and C2 as one period of RRM measurement when performing RRM measurement. Reflected in Figure 4, the terminal device should measure at a period of 10ms or even 5ms. In this case, the power consumption of the terminal device is relatively large.

As shown in FIG. 3 and FIG. 4, in order to measure the SSBs of the local cell and each neighboring cell, when the terminal device performs RRM measurement, it is necessary to consider the periods and positions of the SSBs of the serving cell and all neighboring cells that need to be measured. With such a mechanism, the power consumption of the terminal device is relatively large.

In the technical solution of this application, by associating the SMTC with the SSB, when the terminal device performs RRM measurement, it only needs to determine the SMTC associated with the SSB corresponding to the beam in which it is located according to the association relationship information, so as to perform RRM according to the SMTC measuring. Compared with the prior art solution, the terminal device only needs to perform RRM measurement according to the period of the SMTC associated with the SSB corresponding to the beam in which it is located. The value of the period of the SMTC is no longer affected by the period and position of the SSB of each neighboring cell. Limitation, which can reduce the power consumption of the RRM measurement of the terminal device.

The method 200 is exemplified below with reference to FIG. 5.

Referring to FIG. 5, FIG. 5 is a schematic diagram of an application scenario applicable to an embodiment of the present application. As shown in FIG. 5, the network device 101 transmits 4 beams, which are respectively numbered as beam 1, beam 2, beam 3, and beam 4. The coverage area corresponding to beam 1 is referred to as physical cell identifier (PCI) 1, and the coverage area corresponding to beam 2 is referred to as PCI 2. According to the method 200 provided in this application, the beam on which the terminal device 102 is located is the beam 1. Therefore, when performing the RRM measurement, the terminal device 102 only needs to measure the SSB corresponding to the beam 1. The beam on which the terminal device 103 is located is the beam 2, so the terminal device 103 only needs to measure the SSB corresponding to the beam 2. Specifically, the terminal device 102 and the terminal device 103 determine the SMTC associated with the SSB corresponding to the beam in which the terminal device 102 and the terminal device 103 are based on the association relationship information issued by the network device 101, and perform RRM measurement according to the SMTC. For example, the terminal device 102 determines the SMTC (denoted as SMTC1) associated with the SSB corresponding to the beam 1, and performs RRM measurement on the PCI1 according to the SMTC1. The terminal device 103 determines the SMTC (denoted as SMTC 2) associated with the SSB corresponding to the beam 2 and performs RRM measurement on the PCI 2 according to the SMTC 2.

For example, applying the method 200 of the present application to the scenario shown in FIG. 3 above, since the terminal device no longer performs RRM measurement on the SSBs corresponding to the beams of all neighboring cells, the terminal device has less constraints on the period for selecting the RRM measurement. Therefore, it is more likely to choose a larger RRM measurement period, which has always played a role in reducing power consumption. For example, if the terminal device considers the period and location of the SSB of the serving cell SC and C1, since the period of the SSB of C1 is small (10ms) and the period of the SSB of the SC is large (20ms), the terminal device can choose The larger period of 20ms is used as one period of RRM measurement. In order to further save power consumption, the terminal device can also select an integral multiple of 20ms as a cycle for RRM measurement, for example, 40ms, 80ms, 120ms, and so on.

As another example, the method 200 of the present application is applied in the scenario shown in FIG. 4 above. For the same reason, if the terminal device only considers the period and time-frequency position of the SSB of SC and C1, the terminal device can obviously choose SC and C1 The period of the SSB is larger, that is, 20 ms is selected as one period of the RRM measurement. Alternatively, the terminal device may also choose an integer multiple of 20 ms as one cycle of RRM measurement. Compared with the existing scheme, the terminal equipment can only choose 10ms or even 5ms, which can save power consumption. If the terminal device only considers the period and time-frequency position of the SSB of SC and C2, the terminal device selects the one with the smallest SSB period, that is, selects 20 ms as one period of the RRM measurement. Alternatively, the terminal device may also choose an integer multiple of 20 ms as one cycle of RRM measurement. Compared with the RRM measurement of SC, C1, and C2 performed by the terminal device at the same time, the RRM measurement cycle can be selected to be longer, thereby saving power consumption.

In method 200, if the association relationship information is delivered to the terminal device by the network device, the network device configures the association relationship between the SMTC and the SSB before issuing the association relationship information.

Specifically, the network device may configure an association relationship between the SSB index and the SMTC.

In the embodiment of the present application, the SMTC has one or more configuration parameters. For example, these configuration parameters may include one or more of the period of the SMTC, the duration of the SMTC, the frequency of the SMTC, and the time offset of the SMTC.

The network device may configure one or more of the configuration parameters of the SMTC according to the SSB index. For example, the network device configures one or more of the period of the SMTC, the duration of the SMTC, the frequency of the SMTC, and the time offset of the SMTC according to the SSB index.

Optionally, as an embodiment, the network device may send an indication information to the terminal device, where the indication information is used to instruct the network device not to configure SMTC for one or several SSBs. Alternatively, the indication information may also indicate that the terminal device does not measure the SSB of the neighboring cell.

As an implementation manner, the network device may not associate SMTCs or SMTC parameters for some SSBs, or instruct one or more SSBs not to perform RRM measurement in the neighboring cell, and only perform RRM measurement in the cell or SSB measurement in the cell only. . When the SSB where the terminal is located or the SSB received is not associated with the SMTC parameter, the terminal device can only measure the SSB of the local cell, not the SSB of the neighboring cell, and can also measure all neighboring cells. When the terminal device receives the neighboring cell indication information according to the SSB information, it can measure only the SSB of the cell, not measure the SSB of the neighboring cell, or only perform RRM measurement of the cell, and not perform RRM measurement of the neighboring cell. Neighboring cells perform measurement (RRM measurement).

Optionally, each SSB index corresponds to one SMTC. Alternatively, one SSB index corresponds to multiple SMTCs. Alternatively, one SMTC corresponds to multiple SSB indexes.

Alternatively, one SSB index corresponds to one SMTC, and it can also be expressed as one SSB index corresponding to one SMTC configuration. Here, a SMTC configuration includes one or more configuration parameters of the SMTC. For example, a SMTC configuration may include a period of the SMTC, a frequency point of the neighboring cell, a SSB frequency point of the neighboring cell, and a cell-defined SSB of the neighboring cell. One or more of a frequency point, a duration of the SMTC, a frequency point of the SMTC, and a time offset of the SMTC.

Alternatively, an SSB index corresponds to a neighboring cell, and can also be expressed as a frequency point where an SSB index corresponds to an SSB of an adjacent cell. Or correspond to the frequency of an adjacent cell.

According to the above description, the association information may be carried in any one of PBCH, RMSI, SIB1, SIB2, SIB3, MAC-CE, DCI, RRC, and system information. Specifically, an SMTC field may be set in the information, and the SMTC field is used to carry one or more configuration parameters of the SMTC.

Optionally, as an embodiment, the network device may choose to set one or more configuration parameters of the SMTC as configuration parameters common to the cell.

For example, the configuration parameters of SMTC include the period of SMTC, the duration of SMTC, the frequency of SMTC, and the time offset of SMTC.

Optionally, the SMTC field includes only one of the configuration parameters of the SMTC, and the rest are all configured as configuration parameters common to the cell. For example, the SMTC field only includes the period of the SMTC, and the duration of the SMTC, the frequency of the SMTC, and the time offset of the SMTC are used as configuration parameters common to the cell. For another example, the SMTC field only includes the duration of the SMTC, and the period of the SMTC, the frequency of the SMTC, and the time offset of the SMTC are used as configuration parameters common to the cell. For another example, the SMTC field only includes the frequency of the SMTC, and the period of the SMTC, the duration of the SMTC, and the time offset of the SMTC are used as configuration parameters common to the cell. For another example, the SMTC field only includes the time offset of the SMTC, and the period of the SMTC, the duration of the SMTC, and the frequency of the SMTC are used as common configuration parameters of the cell. The SMTC field in this application is a configuration parameter in the SMTC configuration parameters associated with the SSB.

Optionally, the SMTC field includes only two of the configuration parameters of the SMTC, and the remaining configuration parameters are configured as configuration parameters common to the cell. For example, the SMTC field only includes the period of the SMTC and the duration of the SMTC, and the frequency of the SMTC and the time offset of the SMTC are used as common configuration parameters of the cell. As another example, the SMTC field only includes the period of the SMTC and the frequency of the SMTC, and the duration of the SMTC and the time offset of the SMTC are configured as configuration parameters common to the cell. For another example, the SMTC field only includes the frequency of the SMTC and the time offset of the SMTC, and the period of the SMTC and the duration of the SMTC are configured as configuration parameters common to the cell. No longer enumerated here.

Optionally, the SMTC field includes only three of the configuration parameters of the SMTC, and the remaining configuration parameters are configured as configuration parameters common to the cell. For example, the SMTC field includes the period of the SMTC, the duration of the SMTC, and the frequency of the SMTC. The time offset of the SMTC is configured as a configuration parameter common to the cell. As another example, the SMTC field includes the period of the SMTC, the duration of the SMTC, and the time offset of the SMTC, and the frequency of the SMTC is configured as a configuration parameter common to the cell. No longer list them one by one.

Optionally, the SMTC field includes all SMTC configuration parameters such as the period of the SMTC, the duration of the SMTC, the frequency of the SMTC, and the time offset of the SMTC. The frequency of the SMTC in this application may be only the frequency of the SMTC of the serving cell, or the frequency of the SMTC of the neighboring cell, or the frequency of the neighboring cell. At least one of the SSB frequency of a cell and the SSB frequency of a cell defined by an adjacent cell.

As an implementation manner, the network device may configure the configuration parameters of the SMTC in the order of the SSB index. The network device sequentially configures the configuration parameters of the SMTC associated with each SSB index. Alternatively, the network device may configure K1 SSB indexes to use the same SMTC configuration parameter, that is, K1 SSB indexes are associated with one SMTC.

Optionally, the K1 SSB indexes may be temporally continuous SSB indexes, or may be discontinuous SSB indexes over a period of time.

The network device can also configure one SMTC to associate multiple SSB indexes, or configure one neighboring cell to associate multiple SSB indexes.

As an implementation manner, the network device may be configured as follows: {SMTC1: SSB index i ₁ , SSB index i ₂ , ..., SSB index N ₁ }, {SMTC2: SSB index j ₁ , SSB index j ₂ , ..., SSB index N ₂ }.

Among them, i1, i2, ..., N1 are all positive integers. j1, j2, ..., N2 are all positive integers.

The SSB index may be a direct SSB index representation method. For example, if the SSB index is 1, and it is represented by 6 bits, it is 000001. Or the index of the SSB can be expressed in a bit-mapping manner. For example, a network device has a total of 16 SSBs. The first, second, and third SSBs are associated with an SMTC, or are associated with the configuration parameters of an adjacent cell, which is represented by bit mapping, which is 0000.0000 0000 0111.

The configuration parameters of the neighboring cell may include at least one of the following parameters: one or more of the configuration parameters of the neighboring cell, the SSB frequency of the neighboring cell, and the SMTC of the neighboring cell.

The SMTC in this application may only include the configuration parameters of the SMTC, or only the configuration parameters of the neighboring cells, and may also include the configuration parameters of the neighboring cells and the configuration parameters of the SMTC.

Optionally, as an implementation manner, when the association relationship information indicates an association relationship between one SMTC and multiple SSBs, or when the association relationship information indicates an association relationship between one SMTC and one SSB, multiple SSBs may be performed using SSB grouping. Instructions. In the grouping instruction, SSB grouping refers to grouping all or part of the SSBs that are actually sent or indicated by system messages in a cell (for example, average grouping). The number of allocated groups is M, and the number of SSBs in each group is N. . When one or more SSBs in a group are associated with SMTC, the group indication information is set to 1 or 0. When there is no SSB and SMTC in a group, the group indication information is set to 0 or 1. Then M groups need M bits for indication, and the SSBs in each of the M groups use N bits for indication. As long as there is an SSB associated with SMTC in the group that has an SSB associated with SMTC in the group, the data bit of the SSB data bit position in the group is set to 1 or 0. If there is no SSB in the position, the value is 0 or 1.

For example, a network device has a total of 16 SSBs. It is assumed that the indexes of the 16 SSBs are recorded as indexes 0 to 15 in this order. When the network device configures the association relationship between the 16 SSBs and one SMTC, the 16 SSBs are first divided into 4 groups, which are respectively referred to as group 1 to group 4. Each group includes 4 SSBs. The network device uses 8 bits to indicate whether the 16 SSBs are associated with an SMTC. For example, the relationship information can be expressed as 1100-1111. The first four bits correspond to four groups, and each bit is used to indicate whether there is an SSB associated with the SMTC in the group corresponding to the bit. The next 8 bits indicate which groups are associated with this SMTC, which SSBs are associated with this SMTC. Assume that 1 indicates association and 0 indicates no association. 1100 in the association information indicates that there is an SSB associated with the SMTC in group 1 and group 2, and there is no SSB associated with the SMTC in group 3 and group 4. Further, 1111 indicates that indexes 1, 2, 3, and 4 in group 1 and group 2 are associated with the SMTC.

Another grouping indication method is: for example, a network device has 16 SSBs in total, and it is assumed that the indexes of the 16 SSBs are sequentially recorded as indexes 0 to 15. When the network device configures the association relationship between the 16 SSBs and one SMTC, the 16 SSBs are first divided into 4 groups, which are respectively referred to as group 1 to group 4. Each group includes 4 SSBs. The network device uses 12 bits to indicate whether the 16 SSBs are associated with an SMTC. For example, the relationship information can be expressed as 1100, 001, 1100. The first four bits correspond to four groups, and each bit is used to indicate whether there is an SSB associated with the SMTC in the group corresponding to the bit. The next 8 bits indicate which groups are associated with this SMTC, which SSBs are associated with this SMTC. Assume that 1 indicates association and 0 indicates no association. Therefore, 1100 in the association information indicates that there is an SSB associated with the SMTC in group 1 and group 2, and there is no SSB associated with the SMTC in group 3 and group 4. Further, 0011 indicates that index 2 and index 3 in group 1 are associated with the SMTC. Index 0 and index 1 are not associated with this SMTC. 1100 indicates that index 4 and index 5 in group 2 are associated with the SMTC, and index 6 and index 7 are not associated with the SMTC.

Optionally, when the network device is configured with an association relationship between multiple SMTCs and multiple SSBs, the multiple SSBs may be divided into multiple groups, and each group is uniquely associated with one SMTC of the multiple SMTCs. Alternatively, the multiple SSBs are divided into multiple groups, and each group may be associated with one or more of the multiple SMTCs. The SSB of this group can also be indicated by using the SSB grouping indication of the cell.

When a group is uniquely associated with an SMTC, all SSBs in the group may be associated with the SMTC, or some SSBs in the group may be associated with the SMTC.

For example, a network device has a total of 16 SSBs, which are divided into 4 groups, and each group includes 4 SSBs. Taking one of the four groups as an example, it is assumed that the network device configures this group to be associated with SMTC1, which can be one, two, three, or four SSBs in this group and is associated with SMTC1.

As another example, the network device has a total of 16 SSBs and is divided into 4 groups, which are respectively referred to as Group 1, Group 2, Group 3, and Group 4. Network devices can be configured to associate a unique SMTC with each group. For example, group 1 is associated with SMTC1, group 2 is associated with SMTC2, group 3 is associated with SMTC3, and group 4 is associated with SMTC4. Alternatively, a group can be associated with multiple SMTCs. For example, group 1 is associated with SMTC1 and group 1 is associated with SMTC2. Alternatively, multiple groups can be associated with the same SMTC. For example, group 1, group 2 and group 3 are associated with SMTC1, and group 4 is associated with SMTC2. This grouping may also be indicated in a manner of indicating the SSB grouping of the cell.

Alternatively, the “group” described in the above embodiments may also be referred to as an SSB group.

Optionally, the specific implementation of the grouping of the SSB may be predefined by the network device, or may also be configured by the network device. Optionally, the network device may also determine how to group SSBs according to the number of SSBs actually transmitted, the number of SSBs that may be transmitted, or the total number of SSBs.

As an implementation manner, the network device may group according to the number of SSBs actually transmitted or the number of SSBs that may be transmitted, or all or part of the SSBs indicated in the system message.

See Table 1. In Table 1, M × N indicates that the SSB is divided into M groups, and each group has N SSBs. Let the number of SSBs actually transmitted be L, and satisfy M × N ≧ L. Among them, M, N and L are all positive integers. For example, when L = 56, 7 × 8 indicates that the SSB is divided into 7 groups, and each group includes 8 SSBs. Alternatively, 8 × 7 indicates that the SSB is divided into 8 groups, and each group includes 7 SSBs. Alternatively, 8 × 8 indicates that the SSB is divided into 8 groups, and each group includes 8 SSBs.

Optionally, after the network device groups multiple SSBs, when configuring the association relationship between the SSB and the SMTC, the network device may use all the SSBs of the multiple SSBs or use a part of the multiple SSBs. For example, a network device has a total of 64 SSBs, which are divided into 8 groups, and each group includes 8 SSBs. Network equipment may actually use 56 of these 64 SSBs.

Optionally, as an implementation manner, the network device groups multiple SSBs to obtain multiple groups. There can be no intersection between any two groups. In other words, an SSB can belong to only one group. In this case, in step 220, when the terminal device determines the first SMTC associated with the first SSB according to the first SSB and association relationship information, it first determines which group the first SSB belongs to, and then determines that the SMTC associated with the group is First SMTC. Alternatively, the configuration parameters of the SMTC are directly determined according to the SMTC associated with the SSB.

For example, a network device has four SSBs, which are denoted as SSB1, SSB2, SSB3, and SSB4. Among them, the four SSBs are divided into two groups. The first group is {SSB1, SSB2} and the second group is {SSB3, SSB4}. Assume that the first group of network devices is configured to be associated with SMTC1, and the second group is associated with SMTC2. The network device sends the association relationship information to the terminal device. If the SSB corresponding to the beam where a terminal device is located is SSB3. The terminal device first determines that SSB3 belongs to the second group, and the SMTC2 corresponding to the second group is the first SMTC described in this application. Subsequently, the terminal device uses SMTC2 to perform RRM measurement. Optionally, when indicating the association relationship between the four SSBs and SMTC1, and / or the association relationship between the four SSBs and SMTC2, the network device may use the grouping instruction method described above to perform the instruction.

Optionally, as another implementation manner, the network device groups the SSBs to obtain multiple groups. There can be intersections between any two groups. That is, an SSB may belong to two or more groups. In this case, in step 220, when the terminal device determines the first SMTC corresponding to the first SSB according to the association relationship information, it first determines a plurality of groups to which the first SSB belongs. According to the SMTC corresponding to each group, the terminal device can determine multiple SMTCs. As an implementation manner, the terminal device may select an SMTC with a maximum period from the multiple SMTCs to perform RRM measurement. Alternatively, the terminal device may also randomly select an SMTC, or select it according to other rules, which is not limited in this application.

For example, a network device has a total of 6 SSBs, which are denoted as SSB1, SSB2, SSB3, SSB4, SSB5, and SSB6. Among them, the six SSBs are divided into three groups. The first group is {SSB1, SSB2, SSB3}, the second group is {SSB3, SSB4}, and the third group is {SSB5, SSB6}. Among them, the first group is associated with SMTC1, the second group is associated with SMTC2, and the third group is associated with SMTC3. It is assumed that the SSB corresponding to the beam in which the terminal device is located is SSB3. According to the association relationship information issued by the network device, the terminal device determines that SSB3 corresponds to the first group and the second group. Then SMTC3 corresponds to SMTC1 and SMTC2. In this case, the terminal device can randomly select one of SMTC1 and SMTC2, which can save power consumption compared with the prior art. Furthermore, in order to save more publicity, the terminal device may choose the one with a larger period. Alternatively, the terminal device may also be selected according to other configuration parameters of SMTC1 and SMTC2, or selected according to other principles, which are not limited in this application. Optionally, when indicating the association relationship between the four SSBs and SMTC1, and / or the association relationship between the four SSBs and SMTC2, the network device may use the grouping instruction method described above to perform the instruction.

Optionally, as an implementation manner, the network device may also indicate the association relationship between the SSB and the SMTC to the terminal device through a bitmap. For example, each SSB corresponds to one data bit in the bitmap.

For example, a network device has a total of 16 SSBs. It is assumed that the indexes of the 16 SSBs are recorded as indexes 0 to 15 in this order. When the network device configures the association relationship between the 16 SSBs and one SMTC, the 16 SSBs are first divided into 4 groups, which are respectively referred to as group 1 to group 4. Each group includes 4 SSBs. The network device uses 12 bits to indicate whether the 16 SSBs are associated with an SMTC. For example, the relationship information can be expressed as 1100, 001, 1100. The first four bits correspond to four groups, and each bit is used to indicate whether there is an SSB associated with the SMTC in the group corresponding to the bit. The next 8 bits indicate which groups are associated with this SMTC, which SSBs are associated with this SMTC. Assume that 1 indicates association and 0 indicates no association. Therefore, 1100 in the association information indicates that there is an SSB associated with the SMTC in group 1 and group 2, and there is no SSB associated with the SMTC in group 3 and group 4. Further, 0011 indicates that index 2 and index 3 in group 1 are associated with the SMTC. Index 0 and index 1 are not associated with this SMTC. 1100 indicates that index 4 and index 5 in group 2 are associated with the SMTC, and index 6 and index 7 are not associated with the SMTC.

Optionally, as an implementation manner, the network device may indicate the association relationship between the SMTC and the SSB to the terminal device through the SSB index. For example, each SSB index can include 3 bits, 2 bits, or 6 bits.

Referring to FIG. 6, FIG. 6 is an example of grouping SSBs. As shown in FIG. 6, the total number of SSBs is 16, corresponding to SSB0 to SSB15, as shown in the left side of FIG. The 16 SSBs are divided into 4 groups, and each group includes 4 SSBs. Each line as a group. The SSBs in each group are renumbered. The grouping is shown on the right in Figure 4. SSB0-SSB3 on the left corresponds to the first group (ie, the first line) on the right, and the numbers of the SSBs in the first group are 0 to 3, respectively. SSB4 to SSB7 correspond to the second group (second row), and the numbers in the second group are 0 to 3, respectively. SSB8 to SSB11 correspond to the third group (third row) on the right, and the numbers in the third group are 0-3. SSB12 to SSB15 correspond to the fourth group (fourth row), and the numbers in the fourth group are 0 to 3, respectively.

Taking SMTC1 as an example, it is assumed that the SSBs associated with SMTC1 are configured as SSB1, SSB6, and SSB7. SSB1 is located in the first group (first row), SSB6 and SSB7 are located in the second group (second row), and the third and fourth groups have no SSB associated with SMTC1.

In the following, it is assumed that 1 indicates association, and 0 indicates no association.

A bitmap indication method is 1100 0100 0011. Of these, 1100 is used to indicate whether each group contains the SSB associated with SMTC1. For example, 1100 indicates that the first and second groups contain SSBs associated with SMTC1, and the third and fourth groups do not have SSBs associated with SMTC1. 0100 and 0011 respectively indicate the positions of specific SSBs in the group containing the SSB associated with SMTC1, that is, which SSBs are specifically associated with SMTC1 in the group containing the SSB associated with SMTC1. 0100 indicates that the second SSB of the first group (ie, SSB1) is associated with SMTC1. 0011 indicates that the third and fourth SSBs of the second group (ie, SSB6 and SSB7) are associated with SMTC1.

Another bitmap indication method is 1100 0111. Of these, 1100 is used to indicate whether each group contains the SSB associated with SMTC1. For example, 1100 indicates that the first and second groups contain associated SSBs, and the third and fourth groups do not have SSBs associated with SMTC1.

0111 collectively indicates the position of a specific SSB in the group containing the SSB associated with SMTC1, that is, which SSB is specifically associated with SMTC1 in the group containing the SSB associated with SMTC1. Specifically, in the first and second groups, the last three SSBs are associated with SMTC1, that is, SSB1, SSB2, and SSB3 (numbered after grouping) in the first and second groups are associated with SMTC1. The numbers before grouping are SSB1, SSB2, SSB3, SSB5, SSB6, SSB7. Among them, SSB2, SSB3, and SSB5 are not actually associated with SMTC1, but in order to save the number of bits, a common indication method is adopted, and SSB2, SSB3, and SSB5 are also used as the SSBs associated with SMTC1. Compared with the above instruction (bitmap is 1100 01000011), the two sets of bitmaps are combined into one group, that is, 0100 and 0111 are combined into 0111. In this way, the accuracy of the indication of the SSB associated with SMTC1 is reduced, but 4 bits can be saved compared with the above indication.

In the embodiment shown in FIG. 6, it can be understood that the association relationship information includes two parts of group association information and intra-group association information. When it is assumed that the network device is configured with an association relationship between the SMTC and the SSB, first, the network device divides all or part of the SSBs actually sent in a cell or indicated by a system message into M groups. The group association information is used to indicate one or more association groups associated with the SMTC in the M groups, and the association relationship information in the group is used to instruct each of the association groups of the one or more association groups to neutralize the SMTC. Associated SSB, M is a positive integer.

For example, in the above-mentioned indication method of the first bitmap, 1100 indicates that the first and second groups contain SSBs associated with SMTC1, and the third and fourth groups do not have SSBs associated with SMTC1. The first and second groups here are the association groups associated with SMTC1.

The above bitmap instruction method is referred to as a group instruction for short. The group instruction is issued in a manner similar to that of the precise instruction. It can be issued at one time or multiple times, or only a part of the SSB bitmap. The delivery method is not repeated here.

As another embodiment of the present application, the following signals may also be used to replace the SSBs in the above embodiments: CSI-RS, PDCCH DMRS for paging messages, PDSCH DMRS for paging messages, DMRS for paging messages, DMRS for PBCH, SIB1 DMRS, DMRS of PDCCH of SIB1, DMRS of PDSCH of SIB1, DMRS of common search space, DMRS of control resource set 0, and the like.
