Embodiment 1
[0033] In this embodiment, a resource frequency hopping allocation method is provided.
[0034] Such as figure 2 As shown, the resource frequency hopping allocation method according to the embodiment of the present invention includes: step S202, dividing multiple subcarriers into multiple segments in units of resource blocks, and labeling the multiple segments respectively; Allocating continuous resource blocks in subframes or time slots; and step S206, determining the continuous resources occupied by the user in the next subframe or time slot allocated to the user according to the segment number in the frequency hopping parameter and closing / opening mirroring The segment where the block is located and the position in the segment of the next subframe or time slot allocated to the user; among them, turning off / on mirroring means that the user is in the segment where the resource block is in the next subframe or time slot allocated to it The relative position in is the same as...
example 1
[0048] In Example 1, frequency hopping is performed in units of subframes. The frequency hopping methods of all users in the cell are consistent. The frequency hopping parameters are determined by the absolute subframe number, and mirroring is turned off / on in each segment.
[0049] When performing uplink resource frequency hopping allocation, the 600 subcarriers available in the system are firstly divided into 2 segments in units of resource blocks (each resource block contains 12 subcarriers, a total of 50 resource blocks), and each segment contains 25 resources piece. The sequence number of the resource block corresponding to the first segment is 0, 1, ..., 24 in its segment, and the sequence number of the resource block corresponding to the second segment is 0, 1, ..., 24 in its segment; the segment number Recorded as 0 and 1.
[0050] Such as image 3 As shown, it is assumed that the resource block assigned to the first user for the first time corresponds to the 0th res...
example 2
[0054] In Example 2, frequency hopping is performed in units of subframes. All users in the cell have the same frequency hopping method. Frequency hopping parameters are determined by the time when resource blocks are allocated for the first time. Mirroring is turned off / on in each segment.
[0055] Firstly, the 600 subcarriers available in the system are divided into 2 segments evenly according to resource block units (each resource block contains 12 subcarriers, 50 resource blocks in total), and each segment contains 25 resource blocks. The sequence number of the resource block corresponding to the first segment is 0, 1, ..., 24 in its segment, and the sequence number of the resource block corresponding to the second segment is 0, 1, ..., 24 in its segment; the segment number Recorded as 0 and 1;
[0056] Such as Figure 4 As shown, it is assumed that the resource block assigned to the first user for the first time corresponds to the 0th resource block in the 0th segment of...
