Channel transmission method, electronic device, and storage medium
View Patent ↗A channel transmission method is provided. The channel transmission method comprises: a terminal device determines the initial position of a channel detection time window on the basis of a message sent by a network device, the initial position being positioned after a time delay after RACH timing or PUSCH timing finishes; the time delay is at least two symbols or the time delay is related to a time domain relationship of the RACH timing and PUSCH timing. Another channel transmission method, an electronic device, and a storage medium are also provided.
1 . A method for channel transmission, applicable to a 2-steps random access, comprising:
determining, by a terminal device, a starting position of a time window for channel detection based on a message transmitted by a network device, the starting position being positioned after a time delay which is after an end of a Random Access Channel (RACH) occasion;
wherein the time delay is relevant to a time-domain relationship between the RACH occasion and a Physical Uplink Shared Channel (PUSCH) occasion, and the time delay is relevant to a subcarrier spacing of Physical Downlink Control Channel (PDCCH) or a subcarrier spacing of PUSCH,
wherein responsive to that the time-domain relationship between the RACH occasion and the PUSCH occasion is that the PUSCH occasion is after the RACH occasion, the time delay is not less than a sum of a fixed delay and the time difference between the RACH occasion and the PUSCH occasion,
wherein the starting position is a starting position of a first symbol of a first Control Resource Set (CORESET) after the time delay which is after the end of the RACH occasion; and
wherein the CORESET is a CORESET configured for a Type1 PDCCH common search space, and the Type1-PDCCH common search space, the RACH occasion, and the PUSCH occasion are determined by the terminal device according to the message transmitted by the network device.
2 .

6 . The method of claim 1 , wherein the message is a Radio Resource Control (RRC) message or a system message.
7 . The method of claim 1 , wherein the time delay is a non-fixed value.
8 . A method for channel transmission, applicable to a 2-steps random access, comprising:
determining, by a network device, a starting position of a time window for channel transmission, the starting position being positioned after a time delay which is after an end of a Random Access Channel (RACH) occasion;
wherein the time delay is relevant to a time-domain relationship between the RACH occasion and a Physical Uplink Shared Channel (PUSCH) occasion, and the time delay is relevant to a subcarrier spacing of Physical Downlink Control Channel (PDCCH) or a subcarrier spacing of PUSCH,
wherein responsive to that the time-domain relationship between the RACH occasion and the PUSCH occasion is that the PUSCH occasion is after the RACH occasion, the time delay is not less than a sum of a fixed delay and the time difference between the RACH occasion and the PUSCH occasion, and
wherein the starting position is a starting position of a first symbol of a first Control Resource Set (CORESET) after the time delay which is after the end of the RACH occasion; the method further comprising:
determining, by the network device, a Type1 PDCCH common search space, the RACH occasion, and the PUSCH occasion, wherein the CORESET is a CORESET configured for the Type1-PDCCH common search space.
9 . The method of claim 8 , wherein the time delay is a non-fixed value.
10 . The method of claim 8 , wherein the time-domain relationship between the RACH occasion and the PUSCH occasion is preset.
11 . The method of claim 8 , wherein the fixed delay is one symbol.
12 . The method of claim 8 , wherein the channel comprises PDCCH.
13 . A terminal device, comprising a processor and a memory for storing a computer program executable by the processor, wherein
the processor is configured to run the computer program to determine a starting position of a time window for channel detection based on a message transmitted by a network device, the starting position being positioned after a time delay which is after an end of a Random Access Channel (RACH) occasion;
wherein the time delay is relevant to a time-domain relationship between the RACH occasion and a Physical Uplink Shared Channel (PUSCH) occasion, and the time delay is relevant to a subcarrier spacing of Physical Downlink Control Channel (PDCCH) or a subcarrier spacing of PUSCH,
wherein responsive to that the time-domain relationship between the RACH occasion and the PUSCH occasion is that the PUSCH occasion is after the RACH occasion, the time delay is not less than a sum of a fixed delay and the time difference between the RACH occasion and the PUSCH occasion,
wherein the starting position is a starting position of a first symbol of a first Control Resource Set (CORESET) after the time delay which is after the end of the RACH occasion; and
wherein the CORESET is a CORESET configured for a Type1 PDCCH common search space, and the Type1-PDCCH common search space, the RACH occasion, and the PUSCH occasion are determined by the terminal device according to the message transmitted by the network device.
