example 1

[0113] combine Figure 8 , the collision mechanism between Short / long PUCCH SR and multiple 1-2-bit HARQ-ACK PUCCHs (short PUCCH refers to PF0, PF2, long PUCCH refers to PF1, PF3, PF4). For cases 1 and 2, under the existing combining mechanism, the SR is sent on the PUCCH numbered 2, that is, the combined PUCCH does not conflict with the PUCCH numbered 3, and there is no problem at this time.

[0114] The problem is the following case 3 and case 4. The result of the combination of ① and ② is: if it is positiveSR, the HARQ-ACK is sent on the PUCCH of ①. At this time, the existing mechanism cannot be used to further merge with the PUCCH of number 3. For cases 3 and 4, one of the following merging schemes can be used.

[0115] Scheme 1: All numbers of HARQ-ACK and SR are jointly encoded, and then the corresponding resource set (resource set) is selected according to the final number of UCI bits, and sent according to the PUCCH resource indicated in the DCI. The disadvantage is ...

example 2

[0120] combine Figure 9 , a collision mechanism between Short / long PUCCH SR and at least one HARQ-ACK PUCCH greater than 2 bits.

[0121] Except case2, other cases can be merged according to the existing merge mechanism without any problem. For case 2, the existing mechanism cannot be merged. One of the following options can be used:

[0122] Option 5: Option 1 in Example 1 is adopted.

[0123] Scheme 6: If the SR is long PUCCH, then drop the SR. PUCCHs numbered 2 and 3 can be sent separately.

[0124] Scheme 7: The UCIs of the PUCCHs numbered 1 and 2 are jointly encoded, and then the corresponding resource set is selected according to the final number of UCI bits, and sent according to the PUCCH resources indicated in the DCI. Then, a PUCCH is obtained and the PUCCH numbered 3 is used to determine whether to merge (if it overlaps, merge again).

[0125] Scheme 8: If the SR is a short PUCCH, the scheme 1 in example 1, if the SR is a long PUCCH, the SR is discarded, and ...

example 3

[0128] combine Figure 10 and 11 , the combination of Short / long PUCCH CSI and multiple 1-2-bit HARQ-ACK PUCCHs adopts one of the following schemes:

[0129] Scheme 10: The CSI is placed in the PUCCH of the HARQ-ACK numbered 2 and coded jointly, and the length of the PUCCH used after the joint numbering remains unchanged or does not increase. Alternatively, the base station ensures that its newly selected PUCCH does not collide with the following PUCCH.

[0130] Scheme 11: The PUCCH of the CSI is discarded, and the PUCCHs numbered 2 and 3 are directly sent.

[0131] like Figure 12 As shown, the embodiment of the present application also provides an apparatus for information transmission, including:

[0132] The multiplexing module 21 is configured to multiplex the information carried by the multiple uplink physical channels to one or more first uplink physical channels when there are multiple uplink physical channels in the time slot;

[0133] The transmission module 22 is...

Abstract

The embodiment of the present application discloses a method, device, device, and computer-readable storage medium for information transmission, wherein the method includes: when there are multiple uplink physical channels in a time slot, carrying the multiple uplink physical channels The information is multiplexed to one or more first uplink physical channels; determine that the end position of the one or more first uplink physical channels satisfies the restriction condition, and transmit the information through the one or more first uplink physical channels . In the embodiment of the present application, by making the end position of the first uplink physical channel meet the restriction condition, the timeliness of the uplink physical channel is guaranteed, making the time sequence more compact and efficient.

Description

technical field [0001] This application relates to, but is not limited to, the field of communications, and in particular, to a method, apparatus, device, and computer-readable storage medium for information transmission. Background technique [0002] When multiple uplink physical channels overlap, the solution is usually as follows: first determine that all of the multiple uplink physical channels meet the timing requirements, and the timing requirements are: the first symbol of the earliest physical channel among the multiple uplink physical channels The start time of , not earlier than any one of the end points of the Tn duration after the channel or signal corresponding to each physical channel in the multiple uplink physical channels (n=0, 1, 2...., indicating different the uplink physical channel). Tn is the decoding time of the channel or signal corresponding to each uplink channel and the preparation time for data transmission in multiple uplink physical channels. ...
