Abstract
A communication device for handling a HARQ RTT Timer comprises a storage device for storing instructions and a processing circuit coupled to the storage device. The processing circuit is configured to execute the instructions stored in the storage device. The instructions comprise receiving a first DCI on a DL control channel transmitted by a BS, or being configured a configured DL assignment; and starting a HARQ RTT Timer for the HARQ process, wherein the HARQ RTT Timer counts a time duration from a (n+1)-th TTI to a (n+k+N+3+deltaPDCCH)-th TTI.
Claims15
A communication device for handling a Hybrid Automatic Repeat Request (HARQ) Round-trip Time (RTT) Timer, comprising:
- a storage device, for storing instructions of:
- receiving a first downlink (DL) control information (DCI) on a DL control channel transmitted by a base station (BS), or being configured a configured DL assignment, wherein the first DCI or the configured DL assignment indicates a first DL transmission comprising at least one repetition for a HARQ process of the communication device;
- and
- starting a HARQ RTT Timer for the HARQ process, wherein the HARQ RTT Timer counts a time duration from a (n+1)-th transmission time interval (TTI) to a (n+k+N+3+deltaPDCCH)-th TTI, wherein the n-th TTI comprises a last repetition of the at least one repetition;
- and k is a first interval between the n-th TTI and a first start TTI of a HARQ feedback associated to the first DL transmission, and N is a transmission duration in a plurality of TTIs of the HARQ feedback, and the deltaPDCCH is a second interval from (a last TTI of the plurality of TTIs+4 TTIs) to a second start TTI of a next Physical DL Control Channel (PDCCH) occasion or to a third start TTI of a next PDCCH candidate;
- and
- a processing circuit, coupled to the storage device, configured to execute the instructions stored in the storage device.
A communication device for handling a Hybrid Automatic Repeat Request (HARQ) Round-trip Time (RTT) Timer, comprising:
- a storage device, for storing instructions of:
- receiving a first downlink (DL) control information (DCI) on a DL control channel transmitted by a base station (BS), or being configured a configured uplink (UL) grant, wherein the first DCI or the configured UL grant indicates the communication device to transmit at least one repetition of a first UL transmission using a HARQ process for the first UL transmission;
- and
- starting an UL HARQ RTT Timer for the HARQ process, wherein the UL HARQ RTT Timer counts a time duration from a (n+1)-th transmission time interval (TTI) to a (n+4+deltaPDCCH)-th TTI, wherein the n-th TTI comprises a last repetition of the at least one repetition, and the deltaPDCCH is an interval from (n+5)-th TTI to a first start TTI of a next Physical DL Control Channel (PDCCH) occasion or to a second start TTI of a next PDCCH candidate;
- and
- a processing circuit, coupled to the storage device, configured to execute the instructions stored in the storage device.
A communication device for handling a Hybrid Automatic Repeat Request (HARQ) Round-trip Time (RTT) Timer, comprising:
- a storage device, for storing instructions of:
- receiving a first downlink (DL) control information (DCI) on a DL control channel transmitted by a base station (BS), or being configured a configured DL assignment, wherein the first DCI or the configured DL assignment indicates a first DL transmission comprising at least one repetition for a HARQ process of the communication device;
- and
- starting a HARQ RTT Timer for the HARQ process, wherein the HARQ RTT Timer counts a time duration from a (n+1)-th transmission time interval (TTI) to a (n+k+N+3+deltaPDCCH)-th TTI, wherein the n-th TTI comprises a last repetition of the at least one repetition;
- and k is a first interval between the n-th TTI and a first start TTI of a HARQ feedback associated to the first DL transmission, and N is a transmission duration in a plurality of TTIs of the HARQ feedback, and the deltaPDCCH is a second interval from (a last TTI of the plurality of TTIs+3 TTIs) to a second start TTI of a next Physical DL Control Channel (PDCCH) occasion or to a third start TTI of a next PDCCH candidate, if (the first start TTI of the HARQ feedback+3 TTIs) is earlier than the second start TTI of the next PDCCH occasion or the third start TTI of the next PDCCH candidate;
- and
- a processing circuit, coupled to the storage device, configured to execute the instructions stored in the storage device.
