S410, the network device determines indication information, where the indication information is used to indicate a frequency domain resource offset of the control resource and a frequency domain resource of the control resource, and the frequency domain resource offset of the control resource is an offset relative to the frequency domain resource of the synchronization signal.
The network device determining the indication information may include: the network device generates, configures, stores, and/or predefines or receives the indication from other networks.
One example of such a network device is network device 110.
The indication information may be an index indicating a frequency domain resource offset of the control resource and a frequency domain resource of the control resource.
S420, the network device sends the indication information. Accordingly, the terminal device receives the indication information.
One example of such a terminal device is terminal device 120.
S430, the terminal equipment receives the control resource according to the indication information.
In a first possible implementation manner, when the channel bandwidth of the network device is 10mhz, the subcarrier spacing of the PDCCH is 15khz, the synchronization signal grid is 3.6 mhz, the number of resource blocks of the control resource is 48, that is, the number of resource blocks of the channel bandwidth is 52, the number of resource blocks of the synchronization signal is 20, and the number of resource blocks of the control resource is 48, and 1 resource block is taken as a unit of frequency domain position offset, the frequency domain relative position of the synchronization signal block (SS block, SSB) in the communication system has 33 (that is, 52-20+1) possibilities.
Since 52-48 is 4, there are at most 5 possibilities for the frequency domain position offset for each control resource. Since the number of resource blocks of the synchronization signal grid is 20, the offset corresponding to the next synchronization signal grid can be applied to the case where the relative position exceeds 20 resource blocks.
From the above analysis, it can be known that the frequency domain position offset of the control resource can be indicated only by 4 frequency domain position offsets, and when the 4 frequency domain position offsets are arranged in the size sequence, the difference between two adjacent frequency domain position offsets is 5 resource blocks. If X represents the maximum frequency-domain position offset among the 4 frequency-domain position offsets, the number of resource blocks of the 4 frequency-domain position offsets can be represented as (X, X-5, X-10, X-15). For example, the number of resource blocks of the 4 frequency-domain positional offsets may be (28, 23, 28, 13).
Wherein, in order to ensure that the resource block of the synchronization signal block is located in the resource block of the control resource, the number of resource blocks of the largest frequency domain position offset in the 4 frequency domain position offsets may be greater than or equal to 15 and less than or equal to 28, i.e. 15 ═ X < -28.
In order to ensure that the resource blocks of the synchronization signal block are located in the resource blocks in the remaining minimum system resource concentration portion as much as possible, the number of the resource blocks of the 4 frequency domain position offsets may be (22,17,12, 7); or the number of resource blocks of the 4 frequency-domain position offsets may be (21,16,11, 6).
Optionally, the index value may also be used to indicate the current number of symbols of the control resource, where the current number of symbols of the control resource is 1,2, or 3.
In a second possible implementation manner, when the channel bandwidth of the network device is 20mhz, the subcarrier spacing of the PDCCH is 15khz, the synchronization signal grid is 3.6 mhz, the number of resource blocks of the control resource is 96, that is, the number of resource blocks of the channel bandwidth of the network device is 106, the number of resource blocks of the synchronization signal is 20, and the number of resource blocks of the control resource is 96, and if 1 resource block is taken as a unit of frequency domain position offset, the frequency domain relative position of the synchronization signal block in the communication system has 87 (that is, 106-20+1) possibilities.
Since 106-96 is 10, there are a maximum of 11 possibilities for the frequency domain position offset for each control resource. Since the number of resource blocks of the synchronization signal grid is 20, the offset corresponding to the next synchronization signal grid can be applied to the case where the relative position exceeds 20 resource blocks.
From the above analysis, it can be known that the frequency domain position offset of the control resource can be indicated only by 2 frequency domain position offsets, and when the 2 frequency domain position offsets are arranged in the size sequence, the difference between two adjacent frequency domain position offsets is 10 resource blocks or 11 resource blocks. If X represents the maximum frequency-domain position offset among the 2 frequency-domain position offsets, the number of resource blocks of the 2 frequency-domain position offsets can be represented as (X, X-10) or (X, X-11).
When the 2 frequency-domain position offsets differ by 10 resource blocks, an example of the number of resource blocks of the two frequency-domain position offsets is (43, 33).
When the 2 frequency domain position offsets differ by 10 resource blocks, the number of resource blocks with the largest frequency domain position offset in the 2 frequency domain position offsets may be greater than or equal to 10 and less than or equal to 76, that is, 10 ═ X ═ 76; when there are 11 resource blocks in the 2 frequency-domain position offsets, the number of resource blocks of the largest frequency-domain position offset in the 2 frequency-domain position offsets may be greater than or equal to 11 and less than or equal to 76, i.e. 11 ═ X ═ 76.
Wherein, in order to ensure that the resource block of the synchronization signal block is located in the resource block in the middle of the remaining minimum system resource set as much as possible, when the difference between the 2 frequency domain position offsets is 10 resource blocks, the 2 frequency domain position offsets may be (44, 33); when the 2 frequency-domain position offsets differ by 11 resource blocks, the 2 frequency-domain position offsets may be (44, 33) or (43, 32).
Optionally, the index value is further used to indicate the number of current symbols of the control resource, and the number of current symbols of the control resource is 1,2, or 3.
In a third possible implementation manner, when the channel bandwidth of the network device is 10mhz, the subcarrier spacing of the PDCCH is 30khz, the synchronization signal grid is 3.6 mhz, the number of resource blocks of the control resource is 24, that is, the number of resource blocks of the channel bandwidth of the network device is 24, the number of resource blocks of the synchronization signal is 10, and the number of resource blocks of the control resource is 24, and if 1 resource block is taken as a unit of frequency domain position offset, then there are at most 1(24-24+1) possibilities for the frequency domain position offset of each control resource in the communication system. Since the number of resource blocks of the synchronization signal grid is 10, the offset corresponding to the next synchronization signal grid can be applied to the case where the relative position exceeds 10 resource blocks.
From the above analysis, it can be known that the frequency domain position offset of the control resource can be indicated only by 10 frequency domain position offsets, and when the 10 frequency domain position offsets are arranged in the size sequence, the difference between two adjacent frequency domain position offsets is 1 resource block. If X represents the maximum frequency-domain positional offset among the 10 frequency-domain positional offsets. For example, the number of resource blocks of the 10 frequency domain position offsets may be (0,1,2,3,4,5,6,7,8,9) or (1,2,3, 4,5,6,7,8,9,10) or (2,3,4,5,6,7,8,9,10,11) or (3,4,5,6,7,8,9,10,11,12) or (4,5,6,7,8,9,10,11,12,13) or (5,6,7,8,9,10,11,12,13, 14).
Optionally, the index value may also be used to indicate the number of current symbols of the control resource, where the number of current symbols of the control resource is 2.
In a fourth possible implementation manner, when the channel bandwidth of the network device is 20mhz, the subcarrier spacing of the PDCCH is 30khz, the synchronization signal grid is 3.6 mhz, the number of resource blocks of the control resource is 48, that is, the number of resource blocks of the channel bandwidth of the network device is 51, the number of resource blocks of the synchronization signal is 10, and the number of resource blocks of the control resource is 48, if 1 resource block is taken as a unit of frequency domain position offset, there are at most 4(51-48+1) possibilities for frequency domain position offset of each control resource. Since the number of resource blocks of the synchronization signal grid is 10, the offset corresponding to the next synchronization signal grid can be applied to the case where the relative position exceeds 10 resource blocks.
From the above analysis, it can be known that the frequency domain position offset of the control resource can be indicated only by 3 frequency domain position offsets, and when the 3 frequency domain position offsets are arranged in the size sequence, the difference between two adjacent frequency domain position offsets is 4 resource blocks.
If X represents the maximum frequency-domain position offset among the 3 frequency-domain position offsets, the number of resource blocks of the 2 frequency-domain position offsets can be represented as (X, X +4, X + 8). For example, the number of resource blocks of the 3 frequency domain position offsets may be (15,19,23) or (18,22, 26).
Optionally, the index value is further used to indicate the current number of symbols of the control resource, and the current number of symbols of the control resource is 2 or 3.
Table 10 is an example of a corresponding relationship among the frequency domain position Offset (Offset) of the remaining minimum system information control resource set, the Number of resource blocks (Number of RBs) of the remaining minimum system information control resource set, the synchronization signal/physical broadcast signal block and control resource set multiplexing pattern (SS/PBHC block and control resource set multiplexing pattern), and the Index value (Index) according to the present application.
