In order to meet the challenges of traditional and emerging wireless broadband access technologies from WiMAX, Wi-Fi, and the third-generation mobile communication system (3G) in the broadband wireless access market, 3GPP launched the Universal Mobile Telecommunications System (UMTS) Research on Terrestrial Radio Access (UTRA) Long Term Evolution (LTE) technology to achieve a smooth transition from 3G technology to the third generation mobile communication system (B3G) and the fourth generation mobile communication system 4G. The goal of LTE improvement is to achieve higher data rates, shorter latency, lower cost, higher system capacity and improved coverage.

[03] In order to improve the resource allocation of uplinks in LTE systems, techniques for discontinuous resource allocation have been proposed, for example in the recommendations for LTE-Advanced (LTE-A) systems.

103.

[20] The assigning means 101 assigns at least one resource block group of at least two clusters to the mobile terminal. The at least two clusters satisfy one of the following conditions: the number of uplink resource blocks included in one resource block group of one cluster is different from the number of uplink resource blocks included in one resource block group of another cluster; Alternatively, the number of uplink resource blocks included in at least two resource block groups in each cluster is different from each other.

As shown in FIG. 2, an uplink resource (frequency domain) includes a number of uplink resource blocks (also referred to as resource blocks) 201. These resource blocks can be expressed in frequency order as RB _r RB _N . Number of resource blocks - -

N depends on the uplink bandwidth of the specific system. For example, for a bandwidth of 20 MHz, there can be 100 resource blocks. It can be understood that for the bandwidth of 5, 10, and 15 MHz, there may be a corresponding number of resource blocks.

[22] A number of resource blocks that are contiguous in frequency may form a resource block group 200. These resource block groups can be expressed in the order of frequency range as RBG _r RBG _M . For each resource block group RBG _{1 (>} consecutive resource block groups in frequency may form a cluster. More than one cluster may be formed, for example, two or three. The number of resource block groups of each cluster may be the same or different. All clusters collectively contain all resource block groups. In the case of forming more than one cluster, there may be no other resource block groups (ie, consecutive) between two clusters with close frequency ranges, or there may be a common resource block group (ie, overlap).

The first cluster includes 22 resource block groups arranged in the order of the included resource blocks in the uplink resources, wherein the first to the 22th resource block groups respectively include 2, 1, and 2.

1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1 resource block. The second cluster includes 22 resource block groups arranged in the order of the included resource blocks in the uplink resource, wherein the first to the 22th resource block groups respectively include 2, 1, 2, 1, 2, 1 , twenty one,

2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1 resource block. The third cluster includes 22 resource block groups arranged in the order of the included resource blocks in the uplink resource, wherein the first to the 22th resource block groups respectively include 2, 1, 2, 1, 2, 1 2, 1, 2, 1, 2, 1,

2, 1, 2, 1, 2, 1, 2, 1, 2, 2 resource blocks.

[28] In an alternative embodiment, the resource block group constitutes at least two clusters CLUSTER _r CLUSTER _L . Among these clusters, there are at least two clusters CLUSTE and CLUSTERj, where i≠j, the resource block group RBGp in the cluster CLUSTE and the resource block group RBG _q in the CLUSTERj contain different numbers of resource blocks from each other. Further, there may be more than one combination of the resource block group RBG _P and the resource block group RBGq in which the number of resource blocks are different from each other between the two clusters.

[29] In an exemplary implementation (referred to as implementation 4), taking a bandwidth of 20 MHz as an example, a resource block group constitutes two clusters. The first cluster includes 16 resource block groups arranged in the order of the included resource blocks in the uplink resources, wherein the first to the 16th resource block groups respectively include 3, 3, 3,

3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3, 3 resource blocks. The second cluster includes 18 resource block groups arranged in the order of the included resource blocks in the uplink resource, wherein the first to the 18th resource block groups respectively include 3, 3, 3, 3, 3, 3 , 3, 3, 3, 3, 3, 3, 3,

3, 3, 3, 3, 3, 1 resource block.

[30] In an exemplary implementation (referred to as implementation 5), taking a bandwidth of 20 MHz as an example, a resource block group constitutes three clusters. The first cluster includes 8 resource block groups arranged in the order of the included resource blocks in the uplink resource, where the first to eighth resource block groups respectively include 4, 4, 4,

4, 4, 4, 4, 4 resource blocks. The second cluster includes eight resource block groups arranged in the order of the included resource blocks in the uplink resource, wherein the first to eighth resource block groups respectively include 4, 4, 4, 4, 4, 4 , 4, 1 resource block. The third cluster includes 10 resource block groups arranged in the order of the included resource blocks in the uplink resource, wherein the first to tenth resource block groups respectively include 4, 4, 4, 4, 4, 4 , 4, 4, 4, 3 resource blocks.

[31] Returning to FIG. 1, the computing device 102 calculates a corresponding resource indication value according to the assignment of the resource block group in the cluster for each of the clusters formed by the resource block group. For each resource indication value, - - The resource block group indicated in the corresponding cluster can be parsed according to the resource indication value as a resource block group allocated for the user. Known methods can be utilized to calculate and resolve resource indication values. For example, please refer to

3GPP TS 36.213.

[32] The transmitting device 103 transmits the calculated resource indication value to the mobile terminal.

[33] In one embodiment, for each cluster formed by a resource block group, the resource block groups of any two clusters do not overlap each other, i.e., there is no common resource block group.

[34] Alternatively, in one embodiment, there may be a specific resource block group RBGl = {RB _ir RB _lK} and _{_{RBG2 = {RB jr RB jL}}} . Resource block group RBG1 and RBG2 resource block groups partly overlap, i.e. resource blocks of resource block groups tail portion of RBG1 RB _{1 (KS)} to each resource block RB _lK first resource block group RBG2 portion to an RB RB _{K1 + S} ) the same. The resource block group RBG1 is a resource block group in one cluster, and the resource block group RBG2 is a resource block group in another cluster (ie, the next cluster). Thus, the sequence of resource blocks included in one cluster can partially overlap the sequence of resource blocks contained in the next cluster.

[35] In an exemplary implementation (referred to as implementation 6), taking a bandwidth of 20 MHz as an example, a resource block group constitutes two clusters. The first cluster and the second cluster each include 15 resource block groups arranged in the order of the included resource blocks in the uplink resource, wherein the first to the 15th resource block groups respectively include 3, 4, and 3 , 4, 3, 4, 3, 4, 3, 4, 3, 4, 3, 4, 3 resource blocks. The last four resource blocks contained in the first cluster are the same as the first four resource blocks contained in the second cluster.

[37] As shown in Figure 3, the method begins at step 300.

[38] At step 302, the mobile terminal is assigned at least one resource block group of at least two clusters. The at least two clusters satisfy one of the following conditions: the number of uplink resource blocks included in one resource block group of one cluster is different from the number of uplink resource blocks included in one resource block group of another cluster; Alternatively, the number of uplink resource blocks included in at least two resource block groups in each cluster is different from each other.

[39] The uplink resource (frequency domain) includes several uplink resource blocks (also referred to as resource blocks). These resource blocks can be expressed in frequency order as RB _r RB _N . The number N of resource blocks depends on the uplink bandwidth of the particular system.

[40] Several resource blocks that are contiguous in frequency can form a resource block group. These resource block groups can be expressed in the order of frequency range as RBG _r RBG _M . For each resource block group, RBG _ie contiguous resource block groups can form a cluster. It can constitute more than one cluster, for example two or three. each - - The number of resource block groups of a cluster may be the same or different. All clusters together contain all resource block groups. In the case of constituting more than one cluster, there may be no other resource block groups (ie, consecutive) between two clusters having a close frequency range, or there may be a common resource block group (ie, overlapping).

[41] In one embodiment of the invention, the resource block group constitutes at least two clusters CLUSTER!-CLUSTERL. Each resource block group (RBG) contains CLUSTE _{u -RBG} _lK, at least two resource block group ₁₈₀₁ and 18, where i ≠ j, the resource block group ₁₈₀₁ and 18 included in the resource blocks The numbers are different from each other. In addition, in the same cluster, the resource block group may have more than two resource blocks.

[42] In an alternative embodiment, the resource block group constitutes at least two clusters CLUSTER _r CLUSTERL. In at least one resource block group (RBG) CLUSTE _{u -RBG} _lK contained, at least two resource block group ₁₈₀₁ and 18, where i ≠ j, the resource block group ₁₈₀₁ and 18 included in the resource blocks The numbers are different from each other. In addition, in the same cluster, the resource block group may have more than two resource blocks.

[43] In an alternative embodiment, the resource block group constitutes at least two clusters CLUSTER _r CLUSTER _L . Among these clusters, there are at least two clusters CLUSTE and CLUSTERj, where i≠j, the resource block group RBGp in the cluster CLUSTE and the resource block group RBG _q in the CLUSTE contain different numbers of resource blocks from each other. Further, there may be more than one combination of the resource block group RBG _P and the resource block group RBGq in which the number of resource blocks are different from each other between the two clusters.

[44] In step 304, for each cluster in each cluster formed by the resource block group, a corresponding resource indication value is calculated according to the assignment of the resource block group in the cluster. For each resource indication value, the resource block group indicated in the corresponding cluster can be parsed according to the resource indication value as the resource block group allocated for the user. Known methods can be utilized to calculate and resolve resource indication values. See, for example, 3GPP TS 36.213.

[45] In step 306, the calculated resource indication value is sent to the mobile terminal.

[46] At step 308, the method ends.

[47] In one embodiment, for each cluster formed by a resource block group, the resource block groups of any two clusters do not overlap each other, i.e., there is no common resource block group.

[48] Alternatively, in one embodiment, there may be such a special resource block group

RBGl = {RB _ir RB _lK} and _{_{RBG2 = {RB jr RB jL}}} . Resource block group RBG1 and RBG2 resource block groups partly overlap, i.e. resource blocks of resource block groups tail portion of RBG1 RB _{1 (KS)} to the first part respectively RB _lK resource block groups RBG2 resource blocks RB _U to RB _{j (1+s} ) is the same. Resource block group - -

RBG1 is a resource block group in one cluster, and resource block group RBG2 is a resource block group in another cluster (ie, the next cluster). Thus, the sequence of resource blocks contained in one cluster can partially overlap the sequence of resource blocks contained in the next cluster.

4 is a block diagram showing an exemplary structure of a mobile terminal 400 according to an embodiment of the present invention.

As shown in FIG. 4, the mobile terminal 400 includes a receiving device 401 and a parsing device 402.

The receiving device 401 receives at least one resource indication value. Each resource indication value indicates one resource block group of the corresponding cluster in at least two clusters. The at least two clusters satisfy one of the following conditions: the number of uplink resource blocks included in one resource block group of one cluster is different from the number of uplink resource blocks included in one resource block group of another cluster; Alternatively, the number of uplink resource blocks included in at least two resource block groups in each cluster is different from each other. The number of resource indication values depends on the configuration of the clusters on the base station side (the number of clusters involved, the resource block group included in the cluster, the resource blocks included in the resource block group), and the configuration of the cluster on the mobile terminal side is the same as that of the cluster on the base station side. .

The parsing means 402 determines the resource block group indicated by it based on the received at least one resource indication value as an uplink resource allocated for the mobile terminal. Known methods can be used to resolve resource indicator values. See, for example, 3GPP TS 36.213.

5 is a flow chart showing a method of allocating uplink resources in a mobile terminal according to an embodiment of the present invention.

[54] As shown in Figure 5, the method begins at step 500.

[55] At step 502, at least one resource indication value is received. Each resource indication value indicates one resource block group of the corresponding cluster in at least two clusters. The at least two clusters satisfy one of the following conditions: the number of uplink resource blocks included in one resource block group of one cluster is different from the number of uplink resource blocks included in one resource block group of another cluster; Alternatively, the number of uplink resource blocks included in at least two resource block groups in each cluster is different from each other. The number of resource indication values depends on the configuration of the clusters on the base station side (the number of clusters involved, the resource block group included in the cluster, the resource blocks included in the resource block group), and the configuration of the cluster on the mobile terminal side is the same as that of the cluster on the base station side. .

[56] At step 504, the set of resource blocks indicated by the at least one resource indication value received is determined as the uplink resource allocated for the mobile terminal. Known methods can be used to resolve resource indicator values. See, for example, 3GPP TS 36.213.
