The manner of the bitmap is indicated by using 1 bit (bit) for each RBG.

 In the process of implementing the present invention, the inventor has found that each bit is indicated by using a bitmap by using a bitmap, indicating that the number of bits to be used is equal to the number of RBGs.

析可知当带宽较大， RBG数量较多时， 非连续资源分配方案占用的空口资源开 销较大。 N RBG , where P is the number of RBs in the RBG, and the symbol ""] "is taken up, by the above i

In the scenario of carrier aggregation, the time-frequency resource allocation (Resource Allocation, RA for short) of the Physical Uplink Shared Channel (PUSCH) configured by the base station for the user equipment (User Equipment, UE for short) needs to be In the downlink control information (Downlink Control Information, DCI) of the Physical Downlink Control Channel (PDCCH), the indication is performed in the downlink control information (DCI); A plurality of consecutive resource blocks (RBs) form an RBG, and a plurality of consecutive RBGs form a cluster, which may also be called a cluster. Multiple clusters may be used for carrier aggregation and allocated to the same user equipment.

 FIG. 1 is a schematic flowchart of an embodiment of a resource allocation indication method according to the present invention. As shown in FIG. 1, the embodiment of the present invention includes the following steps:

 Step 101: Obtain a starting resource block group and a terminating resource block group of a cluster allocated to the UE, where the cluster includes at least two resource block groups.

 Step 102: Indicate, by using an indication point, that the initial resource block group and the terminating resource block group are obtained, to obtain resource allocation indication information.

 Step 103: Send the resource allocation indication information to the UE to indicate a time-frequency resource allocated for the UE.

 Specifically, the location information may be sent to the UE through the air interface, so that the UE acquires the time-frequency resource allocated by the base station according to the resource allocation indication information.

 The resource allocation indication method provided by the embodiment of the present invention, by limiting the size of each cluster allocated for the UE to include at least two resource block groups, is convenient for indicating the location of the cluster, and does not need to additionally indicate the resource blocks occupied by the cluster. Therefore, the resource allocation indication information of the resource block group is represented by using a small number of bits, which saves the overhead of indicating the resource block.

 Further, on the basis of the foregoing embodiment shown in FIG. 1, step 102 may be specifically: using a indication point by using an indication point of the initial resource block group and the termination resource block group of the cluster allocated for the UE, and the obtained indication points The number is twice the number of clusters allocated to the UE; the indication points are jointly encoded to obtain resource allocation indication information.

In order to more clearly understand the technical solution of the embodiment shown in FIG. 1, the embodiment shown in FIG. 1 will be described in detail below with reference to FIG. 2 and FIG. The starting position and the ending position shown in FIG. 2 and FIG. 3 are respectively a starting resource block group and a terminating resource block group in each cluster, which are only convenient for image description when describing FIG. 2 and FIG. 3 The starting resource block group is called the starting position, and the terminating resource block group is called the terminating bit. Set.

2 is a schematic diagram of two non-contiguous clusters, and FIG. 3 is a schematic diagram of non-contiguous clusters in the embodiment shown in FIG. 1. As shown in FIG. 2, the time-frequency resource includes two clusters, and the present invention is implemented. For convenience of description, the clusters from left to right are referred to as the first cluster and the second cluster respectively. In (1) of FIG. 2, the first cluster contains two consecutive RBGs, and the second The cluster contains four consecutive RBGs; in (2) of Figure 2, the first cluster contains one RBG, and the second cluster contains four consecutive RBGs; in (3) of Figure 2, One cluster contains two consecutive RBGs, and the second cluster contains one RBG; in (4) of Figure 2, the first cluster contains one RBG, and the second cluster contains one RBG; The above four cases can be known that: the starting position and the ending position of the first cluster of the two clusters and the starting position and the ending position of the second cluster have the following four situations: First, the first one The starting position and the ending position of the cluster and the second cluster are different, and four indicating points are required to indicate the four position information; Second, the starting position of the first cluster coincides with the ending position, and the starting position of the second cluster is different from the ending position. In this case, three indicating points are required to indicate the three position information; third, the first cluster The starting position of the second cluster is different from the ending position. The starting position of the second cluster coincides with the starting position and the ending position of the ending position. In this case, three indicating points are required to indicate the three position information; fourth, the first cluster The start position and the end position of the second cluster coincide with each other, and two indication points are required to indicate the two position information; further, if the indication point is three, the first indication point represents the first The starting and ending positions of the clusters, the second and third indicator points representing the starting and ending positions of the second cluster, or the first two indicating points indicating the starting and ending positions of the first cluster The third indicator point indicates the second cluster. If the indication point is two, and the UE does not know that there are several clusters, the UE cannot distinguish at this time whether the two indication points indicate the start position and the end position of a cluster, or indicate the two start positions and Terminate the clusters where the positions coincide. Embodiments of the present invention limit the number of RBGs included in each cluster (ie, the size of clusters), that is, by limiting the number of RBGs included in each cluster to be greater than or equal to 2 RBGs: ^{Ν ≥1} Thus, the three scenarios with less probability of (2), (3), and (4) in Fig. 2 are excluded. If the case of ^= ^{≥ 2} is not met, frequency hopping (Frequency) can be used. Hopping, abbreviation: FH) or the like for indicating the start and end positions of Scenario clusters; cluster and location information can be derived as shown in FIG. 3 by limiting the ² ^ = ≥, the In this scenario, the indication of the start position and the end position of each cluster is clear and clear, and there is no need to use extra bits to distinguish between (2) and (3) in Figure 2, and no additional bit indication is needed. The number of clusters allocated to the UE; further, if a time-frequency resource includes M (M is a natural number) non-contiguous clusters, the embodiment shown in FIG. 2 uses 2M indicator points to indicate each cluster. The resource allocation indication information in the embodiment shown in FIG. 1 is obtained by jointly coding the indication point and the termination position.

 4 is a schematic flowchart of another embodiment of a resource allocation indication method according to the present invention. This embodiment is exemplified by an example in which each cluster allocated by a UE includes a resource block group. As shown in FIG. 4, the embodiment of the present invention is shown in FIG. Including the following steps:
