Measurement method and apparatus for supporting mobility in communication system
View Patent ↗Disclosed are a measurement method and a measurement apparatus for supporting mobility in a communication system. An operation method of a terminal may comprise receiving, from a base station, control information including first information indicating one or more physical uplink shared channel (PUSCH) interlaces configured in an unlicensed band; identifying frequency resources corresponding to the one or more PUSCH interlaces; and transmitting a PUSCH to the base station using the frequency resources of the unlicensed band. Thus, the performance of the communication system can be improved.
1. An operation method of a terminal in a communication system, the operation method comprising:
receiving, from a base station, first control information including first information indicating a physical uplink shared channel (PUSCH) interlace configured in an unlicensed band and second information indicating one or more resource block (RB) sets;
identifying frequency resources corresponding to the PUSCH interlace in the one or more RB sets; and
transmitting a PUSCH to the base station using the identified frequency resources in the unlicensed band,
wherein each of the one or more RB sets includes one or more RBs, the PUSCH interlace is indicated by an index, the index being the first information when a subcarrier spacing of a bandwidth part (BWP) to which the PUSCH interlace belongs is a first value, and the PUSCH interlace is indicated by a bitmap, the bitmap being the first information when the subcarrier spacing is a second value.
2. The operation method according to claim 1 , wherein the first information is located prior to the second information within the first control information, a first zero bit is prepended to the first information within the first control information, and a second zero bit is appended to the second information within the first control information.
3. The operation method according to claim 1 , further comprising receiving second control information including third information indicating an available RB set from the base station, and the identified frequency resources belong to the available RB set in the one or more RB sets indicated by the first control information.
4. The operation method according to claim 3 , wherein the second control information further includes fourth information indicating valid duration.
5. The operation method according to claim 3 , wherein, when the second control information further includes fifth information indicating a slot structure and a plurality of pieces of second control information are received from the base station, the plurality of pieces of second control information indicate that a same slot structure is expected by the terminal.
6. The operation method according to claim 1 , wherein each of bits included in the bitmap indicates one PUSCH interlace allocated for the terminal.
7. The operation method according to claim 1 , wherein the index indicates a combination of one or more PUSCH interlaces allocated for the terminal.
8. The operation method according to claim 7 , wherein the index includes information indicating a starting PUSCH interlace among the one or more PUSCH interlaces and information indicating a number of the one or more PUSCH interlaces.
9. The operation method according to claim 1 , wherein, when the first information indicates a plurality of PUSCH interlaces, the frequency resources are identified by a combination of the plurality of PUSCH interlaces in the one or more RB sets.
10. The operation method according to claim 1 , wherein, when a plurality of RB sets are indicated by the first control information, a guard band which being located between the plurality of RB sets is determined by the terminal.
11. An operation method of a base station in a communication system, the operation method comprising:
transmitting, to a terminal, first control information including first information indicating a physical uplink shared channel (PUSCH) interlace configured in an unlicensed band and second information indicating one or more resource block (RB) sets;
identifying frequency resources corresponding to the PUSCH interlace in the one or more RB sets; and
performing a monitoring operation on the identified frequency resources in the unlicensed band to obtain a PUSCH from the terminal,
wherein each of the one or more RB sets includes one or more RBs, the first information is a bitmap when a subcarrier spacing of a bandwidth part (BWP) to which the PUSCH interlace belongs is a second value, and each of bits included in the bitmap indicates one PUSCH interlace allocated for the terminal.
12. The operation method according to claim 11 , wherein a scheme for indicating the PUSCH interlace depends on the subcarrier spacing.
13. The operation method according to claim 12 , wherein the PUSCH interlace is indicated by an index, the index being the first information when the subcarrier spacing is a first value.
14. The operation method according to claim 11 , wherein the first information is located prior to the second information within the first control information, a first zero bit is prepended to the first information within the first control information, and a second zero bit is appended to the second information within the first control information.
15. The operation method according to claim 11 , further comprising transmitting second control information including third information indicating an available RB set to the terminal, and the identified frequency resources belong to the available RB set in the one or more RB sets indicated by the first control information.
16. The operation method according to claim 13 , wherein the index indicates a combination of one or more PUSCH interlaces allocated for the terminal.
17. The operation method according to claim 16 , wherein the index includes information indicating a starting PUSCH interlace among the one or more PUSCH interlaces and information indicating a number of the one or more PUSCH interlaces.
