Device and method for allocating and indicating resources in wireless communication system
Disclosed is a 5G (5 th generation) or pre-5G communication system for supporting a data transmission rate higher than that of a 4G (4 th generation) communication system such as a long term evolution (LTE). The present disclosure is for allocating and indicating resources in a wireless communication system, and an operation method of a base station comprises the steps of: allocating a first resource for a first service; allocating a second resource for a second service in consideration of the first resource; and transmitting resource allocation information on the second resource and data of the second service, wherein the second resource is discontinuously allocated, at a frequency axis, in a logical or physical manner, and the resource allocation information indicates the second resource by using at least one starting location and at least one length.
1. A method performed by a base station in a wireless communication system, the method comprising:
allocating a first resource for a first service;
allocating a second resource for a second service based on the first resource; and
transmitting resource allocation information regarding the second resource and data of the second service,
wherein the second resource includes a first part and a second part that are discontinuous in a frequency axis,
wherein the resource allocation information indicates the second resource using at least one start point and at least one length, and
wherein allocating the second resource comprises:
allocating a remaining resource, after excluding the first resource, for the second service in a slot corresponding to the second service;
puncturing at least a part of the first resource if a size of a resource required for the second service is greater than a size of the remaining resource; and
allocating at least the part of the first resource, for the second service.
2. The method of claim 1 , wherein the resource allocation information further comprises an offset for adjusting a minimum index or a maximum index of candidate resource blocks indicated by the resource allocation information.
3. The method of claim 1 , wherein the resource allocation information comprises a value indicating one of a plurality of combinations derived from allocable resource blocks, and
at least one combination of the plurality of combinations comprises resource blocks, a number of which is smaller than a total number of the allocable resource blocks, and comprises a resource block having a minimum index and a resource block having a maximum index among the allocable resource blocks.
4. The method of claim 3 , wherein combinations including discontiguously distributed resource blocks among the plurality of combinations are defined to be indicated by contiguous values.
5. A method performed by a terminal in a wireless communication system, the method comprising:
receiving resource allocation information regarding a second resource for a second service which is allocated based on a first resource for a first service; and
receiving data based on the resource allocation information,
wherein the second resource includes a first part and a second part that are discontinuous in a frequency axis,
wherein the resource allocation information indicates the second resource using at least one start point and at least one length,
wherein the second resource comprises a remaining resource, after excluding the first resource, for the second service in a slot corresponding to the second service, and
wherein if a size of a resource required for the second service is greater than a size of the remaining resource, the second resource comprises at least a part of the first resource which is punctured and is allocated for the second service.
6. The method of claim 5 , wherein the resource allocation information further comprises an offset for adjusting a minimum index or a maximum index of candidate resource blocks indicated by the resource allocation information.
7. The method of claim 5 , wherein the resource allocation information comprises a value indicating one of a plurality of combinations derived from allocable resource blocks, and
at least one combination of the plurality of combinations comprises resource blocks, a number of which is smaller than a total number of the allocable resource blocks, and comprises a resource block having a minimum index and a resource block having a maximum index among the allocable resource blocks.
8. The method of claim 7 , wherein combinations including discontiguously distributed resource blocks among the plurality of combinations are defined to be indicated by contiguous values.
9. A terminal in a wireless communication system, the terminal comprising:
a transceiver configured to receive resource allocation information regarding a second resource for a second service allocated based on a first resource for a first service, and to receive data based on the resource allocation information,
wherein the second resource includes a first part and a second part that are discontinuous in a frequency axis,
wherein the resource allocation information indicates the second resource using at least one start point and at least one length,
wherein the second resource comprises a remaining resource, after excluding the first resource, for the second service in a slot corresponding to the second service, and
wherein if a size of a resource required for the second service is greater than a size of the remaining resource, the second resource comprises at least a part of the first resource which is punctured and is allocated for the second service.
10. The terminal of claim 9 , wherein the resource allocation information further comprises an offset for adjusting a minimum index or a maximum index of candidate resource blocks indicated by the resource allocation information.
11. The terminal of claim 9 , wherein the resource allocation information comprises a value indicating one of a plurality of combinations derived from allocable resource blocks, and
at least one combination of the plurality of combinations comprises resource blocks, a number of which is smaller than a total number of the allocable resource blocks, and comprises a resource block having a minimum index and a resource block having a maximum index among the allocable resource blocks.
12. The terminal of claim 11 , wherein combinations including discontiguously distributed resource blocks among the plurality of combinations are defined to be indicated by contiguous values.
