Abstract
The present invention provides a method and a communication device for performing transmission(s) or reception(s) on BWPs associated to a carrier or a cell by using the same Hybrid Automatic Repeat Request (HARQ) entity and performing transmission(s) or reception(s) on BWPs associated to different carriers or cells by using different HARQ entities.
Claims14
A communication device for performing communication in bandwidth parts (BWPs), comprising:
- a storage device;
- and
- a processing circuit, coupled to the storage device, wherein the storage device stores, and the processing circuit is configured to execute instructions of:
- receiving a first command from a base station (BS) in a first BWP, wherein the first command comprises a first Hybrid Automatic Repeat Request (HARQ) process number and a first uplink (UL) grant which assigns at least one first physical resource block (PRB);
- transmitting a first transmission to the BS on the at least one first PRB according to a first HARQ process of a first HARQ entity, wherein the communication device associates the first HARQ process to the first HARQ process number;
- receiving a second command from the BS in a second BWP, wherein the second command comprises a second HARQ process number and a second UL grant which assigns at least one second PRB;
- and
- transmitting a second transmission to the BS on the at least second PRB according to a second HARQ process of the first HARQ entity, wherein the communication device associates the second HARQ process to the second HARQ process number.

Abase station (BS) for performing communication in bandwidth parts (BWPs), comprising:
- a storage device;
- and
- a processing circuit, coupled to the storage device, wherein the storage device stores, and the processing circuit is configured to execute instructions of:
- transmitting a first command to a communication device in a first bandwidth part (BWP), wherein the first command comprises a first Hybrid Automatic Repeat Request (HARQ) process number and a first uplink (UL) grant which assigns at least one first physical resource block (PRB);
- receiving a first transmission from the communication device on the at least one first PRB according to a first HARQ process of a first HARQ entity, wherein the BS associates the first HARQ process to the first HARQ process number;
- transmitting a second command to the communication device in a second BWP, wherein the second command comprises a second HARQ process number and a second UL grant which assigns at least one second PRB;
- and
- receiving a second transmission from the communication device on the at least second PRB according to a second HARQ process of the first HARQ entity, wherein the BS associates the second HARQ process to the second HARQ process number.

- receiving a first command from a base station (BS) in a first BWP, wherein the first command comprises a first Hybrid Automatic Repeat Request (HARQ) process number and a first downlink (DL) assignment which assigns at least one first physical resource block (PRB);
- receiving a first transmission from the BS on the at least one first PRB according to a first HARQ process of a first HARQ entity, wherein the communication device associates the first HARQ process to the first HARQ process number;
- receiving a second command from the BS in a second BWP, wherein the second command comprises a second HARQ process number and a second DL assignment which assigns at least one second PRB;
- and
- receiving a second transmission from the BS on the at least second PRB according to a second HARQ process of the first HARQ entity, wherein the communication device associates the second HARQ process to the second HARQ process number.
