Channel transmission method, electronic device, and storagr medium
A channel transmission method is provided, which includes that: a terminal device determines, according to at least one of the following: protocol convention, information received by the terminal device, a transmission parameter of a first transport block, a joint channel estimation window length, and a slot structure, the number of time domain units mapped by the first transport block.
1 . A method for a channel transmission, comprising:
determining, by a terminal device, a number of time domain units mapped by a first transmission block according to a protocol, information received by the terminal device, a transmission parameter for the first transmission block, a joint channel estimation window length and a slot structure;
wherein a first information field in the information received by the terminal device is used to indicate the number of time domain units mapped by the first transmission block; and a bit value of the first information field is the number of time domain units mapped by the first transmission block.
2 . The method of claim 1 , wherein the information received by the terminal device comprises at least one of:
Downlink Control Information (DCI), a Radio Resource Control (RRC) signaling or a Media Access Control Control Element (MAC CE).
3 . The method of claim 1 , wherein a time domain unit comprises a slot.
4 . The method of claim 1 , wherein the first transmission block is carried on at least one of a Physical Uplink Shared Channel (PUSCH) or a Physical Downlink Shared Channel (PDSCH).
5 . The method of claim 1 , further comprising:
determining, by the terminal device, whether to map the first transmission block to at least two time domain units according to the number of time domain units.
6 . The method of claim 1 , further comprising:
determining, by the terminal device, whether to map the first transmission block to at least two time domain units according to received indication information.
7 . A terminal device, comprising:
a first processor, configured to determine a number of time domain units mapped by a first transmission block according to a protocol, information received by the terminal device, a transmission parameter for the first transmission block, a joint channel estimation window length and a slot structure;
wherein a first information field in the information received by the terminal device is used to indicate the number of time domain units mapped by the first transmission block; and a bit value of the first information field is the number of time domain units mapped by the first transmission block.
8 . The terminal device of claim 7 , wherein the first processor is further configured to determine whether to map the first transmission block to at least two time domain units according to the number of time domain units.
9 . The terminal device of claim 7 , wherein the first processor is further configured to determine whether to map the first transmission block to at least two time domain units according to received indication information.
10 . A network device, comprising:
a second processor, configured to determine a number of time domain units mapped by a first transmission block according to a protocol, a transmission parameter for the first transmission block, a joint channel estimation window length and a slot structure;
a first transmitter, configured to transmit information to a terminal device, wherein a first information field in the information is used for the terminal device to determine the number of time domain units mapped by the first transmission block; and a bit value of the first information field is the number of time domain units mapped by the first transmission block.
11 . The network device of claim 10 , wherein the information comprises at least one of:
Downlink Control Information (DCI), a Radio Resource Control (RRC) signaling and a Media Access Control Control Element (MAC CE).
12 . The network device of claim 10 , wherein a time domain unit comprises a slot.
13 . The network device of claim 10 , wherein the second processor is further configured to determine whether to map the first transmission block to at least two time domain units according to the number of time domain units.
