Resource allocation-related signaling method in wireless communication system and device using same
Provided are a signaling method of a device in a wireless communication system and a device using same. The method comprises: transmitting, to a terminal via an upper layer signal, first information info fining about a first resource unit used for interleaving; and performing interleaving for a particular resource for the terminal by the first resource unit, wherein the information informing about the first resource unit is signaled to the terminal separately from second information for informing about a second resource unit used when a base station allocates resources for the terminal.
1. A method of receiving a signal in a wireless communication system, the method performed by a user equipment (UE) and comprising:
determining a number of resource block groups (RBGs), (N RBG ), that are allocated to the UE for a downlink bandwidth, wherein the downlink bandwidth comprises a plurality of resource blocks, and wherein a number of the plurality of resource blocks is N DL RB resource blocks;
determining a size of each of the N RBG RBGs; and
receiving the signal through at least one RBG of the N RBG RBGs,
wherein N RBG is floor (N DL RB /P) and based on (N DL RB mod P) > 0, where P is a size of one RBG configured for the downlink bandwidth:
(i) (N RBG -ceil((N DL RB mod P)/P)) RBGs among the N RBG RBGs are of size P, and
(ii) only one RBG among the N RBG RBGs is of size (P + (N DL RB mod P)).
2. The method of claim 1 , wherein the RBG is configured with a plurality of resource blocks.
3. The method of claim 1 , wherein the size P indicates that an RBG is configured with P resource blocks.
4. A user equipment (UE), comprising:
a transceiver configured to transmit and receive radio signals;
a processor operatively coupled with the transceiver; and
a computer memory operatively coupled with the processor and storing instructions that, based on being executed by the processor, perform operations comprising:
determining a number of resource block groups (RBGs), N RGB , that are allocated to the UE for a downlink bandwidth, wherein the downlink bandwidth comprises a plurality of resource blocks, and wherein a number of the plurality of resource blocks is N DL RB resource blocks;
determining a size of each of the N RBG RBGs; and
receiving, through the transceiver, a signal through at least one RBG of the N RBG RBGs,
wherein N RBG is floor (N DL RB /P) and based on (N DL RB mod P) > 0, where P is a size of one RBG configured for the downlink bandwidth:
(i) (N RBG -ceil((N DL RB mod P)/P)) RBGs among the N RBG RBGs are of size P, and
(ii) only one RBG among the N RBG RBGs is of size (P + (N DL RB mod P).
5. The UE of claim 4 , wherein the RBG is configured with a plurality of resource blocks.
6. The UE of claim 4 , wherein the size P indicates that an RBG is configured with P resource blocks.
7. A processing device configured to control a user equipment (UE) to operate in a wireless communication, the processing device comprising:
a processor; and
a computer memory operatively coupled to the processor and storing instructions that, based on being executed by the processor, perform operations comprising:
determining a number of resource block groups (RBGs), N RBG , that are allocated to the UE for a downlink bandwidth, wherein the downlink bandwidth comprises a plurality of resource blocks, and wherein a number of the plurality of resource blocks is N DL RB resource blocks;
determining a size of each of the N RBG RBGs; and
receiving a signal through at least one RBG of the N RBG RBGs,
wherein N RBG is floor (N DL RB /P) and based on (N DL RB mod P) > 0, where P is a size of one RBG configured for the downlink bandwidth:
(i) (N RBG -ceil((N DL RB mod P)/P)) RBGs among the N RBG RBGs are of size P, and
(ii) only one RBG among the N RBG RBGs is of size (P + (N DL RB mod P).
8. The processing device of claim 7 , wherein the RBG is configured with a plurality of resource blocks.
9. The processing device of claim 7 , wherein the size P indicates that an RBG is configured with P resource blocks.
