Method and device for resource allocation
Embodiments of the disclosure provide a method and device for allocating resource in a wireless communication system. The method comprises: determining a set of user equipment (UEs) requesting for resource allocation based on resource available in the wireless communication system and a resource use requirement; allocating the resource to the set of UEs according to the resource use requirement; and sending information about the allocated resource to each UE in the set of UEs.
1. A method performed by a base station, the method comprising:
allocating, to an User Equipment (UE), a set of resource blocks whose corresponding set of indices are calculated by the UE by using an expression:
S+n+(i×P),
wherein
S is a numerical index of a first resource block of the resource blocks within bandwidth configured for communication between the base station and the UE,
n is one or more integer(s) equal to or greater than 0, wherein each value of n is assigned to the expression S+n+(i×p),
i=0,1, . . . , m−1, wherein is equal to, or is a floor value of a number of resource blocks corresponding to the bandwidth divided by P, wherein each value of i from 0 to m−1 is assigned to the expression S+n+(i×P), where each value of S+n+(i×P) depends on which value of i is assigned, and
P is either 5 or 10; and
receiving an uplink transmission using the set of the resource blocks.
2. The method of claim 1 , wherein the set of the resource blocks includes discontinuous resource blocks.
3. The method of claim 1 , wherein the base station indicates the set of the resource blocks is indicated by a bitmap.
4. The method of claim 1 , wherein multiple values of n are allocated per each of the set of the resource blocks, where each of the multiple values of n is assigned to the expression S+n+(i×P).
5. The method of claim 4 , wherein n=0, k, and k>0.
6. A method performed by a User Equipment (UE), the method comprising:
being allocated a set of resource blocks by a base station;
calculating a set of indices corresponding to the set of the allocated resource blocks by using an expression:
S+n+(i×P),
wherein
S is a numerical index of a first resource block of the resource blocks within bandwidth configured for communication between the base station and the UE,
n is one or more integer(s) equal to or greater than 0 wherein each value of n is assigned to the expression S+n+(i×P),,
i=0,1, . . . , m−1, wherein is equal to, or is a floor value of a number of resource blocks corresponding to the bandwidth divided by P, wherein each value of i from 0 to m−1 is assigned to the expression S+n+(i×P), where each value of S+n+(i×P) depends on which value of i is assigned, and
P is either 5 or 10; and
performing an uplink transmission using the set of the resource blocks.
7. The method of claim 6 , wherein the set of the resource blocks includes discontinuous resource blocks.
8. The method of claim 6 , wherein the set of the resource blocks is indicated by a bitmap.
9. The method of claim 6 , wherein multiple values of n are allocated per each of the set of the resource blocks, where each of the multiple values of n is assigned to the expression S+n+(i×P).
10. The method of claim 9 , wherein n=0, k, and k>0.
11. A base station comprising a memory that stores a set of instructions; and at least one hardware processor configured to execute the set of instructions to:
allocate, to an User Equipment (UE), a set of resource blocks whose corresponding set of indices are calculated by the UE by using an expression:
S+n+(i×P),
wherein
S is a numerical index of a first resource block of the resource blocks within bandwidth configured for communication between the base station and the UE,
n is one or more integer(s) equal to or greater than 0, wherein each value of n is assigned to the expression S+n+(i×P),
i=0, 1, . . . , m−1, wherein is equal to, or is a floor value of a number of resource blocks corresponding to the bandwidth divided by P, wherein each value of i from 0 to m−1 is assigned to the expression S+n+(i×P), where each value of S+n+(i×P) depends on which value of i is assigned, and
P is either 5 or 10; and
receiving an uplink transmission using the set of the resource blocks.
12. The base station of claim 11 , wherein the set of the resource blocks includes discontinuous resource blocks.
13. The base station of claim 11 , wherein the set of the resource blocks is indicated by a bitmap.
14. The base station of claim 11 , wherein multiple values of n are allocated per each of the set of the resource blocks, where each of the multiple values of n is assigned to the expression S+n+(i×P).
15. The base station of claim 14 , wherein n=0, k, and k>0.
