Method, device and computer storage medium for communication
Embodiments of the present disclosure relate to methods, devices and computer storage media for communication. A method comprises transmitting, from a network device to a terminal device, downlink control information for scheduling transmissions of data and channel state information (CSI) from the terminal device; receiving the data from the terminal device based on a first slot offset configured for uplink data transmission or a second slot offset configured for the CSI; and receiving the CSI from the terminal device based on the second slot offset. As such, in case of higher frequency band with larger subcarrier spacing, embodiments of the present disclosure can support uplink data scheduling and A-CSI report triggering with same DCI.
1 . A method performed by a terminal device, the method comprising:
receiving, from a network device, a downlink control information (DCI) indicating a slot offset,
wherein a first candidate value of the slot offset ranges from 0 to 32 in a case where a first subcarrier spacing (SCS) is configured and a second candidate value of the slot offset ranges from 0 to 128 in a case where a second SCS is configured, and a subcarrier spacing value of the first SCS is less than a subcarrier spacing value of the second SCS, and
wherein the subcarrier spacing value of the second SCS is 480 kHz or 960 kHz; and
transmitting, to the network device, a channel state information (CSI) report triggered by the DCI based on the slot offset.
2 . The method of claim 1 , further comprising:
ignoring the DCI in a case where a first uplink symbol to carry the CSI report starts earlier than a first symbol configured for the second SCS.
3 . The method of claim 2 , wherein the first symbol configured for the second SCS with the subcarrier spacing value of 960 kHz starts later than the first symbol configured for the second SCS with the subcarrier spacing value of 480 kHz.
4 . A terminal device, comprising:
at least one processor configured to cause the terminal device to:
receive, from a network device, a downlink control information (DCI) indicating a slot offset,
wherein a first candidate value of the slot offset ranges from 0 to 32 when a first subcarrier spacing (SCS) is configured and a second candidate value of the slot offset ranges from 0 to 128 when a second SCS is configured, and a subcarrier spacing value of the first SCS is less than a subcarrier spacing value of the second SCS, and
wherein the subcarrier spacing value of the second SCS is 480 kHz or 960 kHz; and
transmit, to the network device, a channel state information (CSI) report triggered by the DCI based on the slot offset.
5 . The terminal device of claim 4 , wherein the at least one processor is further configured to cause the terminal device to:
ignore the DCI in a case where a first uplink symbol to carry the CSI report starts earlier than a first symbol configured for the second SCS.
6 . The terminal device of claim 5 , wherein the first symbol configured for the second SCS with the subcarrier spacing value of 960 kHz starts later than the first symbol configured for the second SCS with the subcarrier spacing value of 480 kHz.
7 . A method performed by a network device, the method comprising:
transmitting to a terminal device, a downlink control information (DCI) indicating a slot offset,
wherein a first candidate value of the slot offset ranges from 0 to 32 in a case where a first subcarrier spacing (SCS) is configured and a second candidate value of the slot offset ranges from 0 to 128 in a case where a second SCS is configured, a subcarrier spacing value of the first SCS is less than a subcarrier spacing value of the second SCS, and
wherein the subcarrier spacing value of the second SCS is 480 kHz or 960 kHz; and
receiving, from the terminal device, a channel state information (CSI) report triggered by the DCI based on the slot offset.
8 . The method of claim 7 , wherein the first symbol configured for the second SCS with the subcarrier spacing value of 960 kHz starts later than the first symbol configured for the second SCS with the subcarrier spacing value of 480 kHz.
