Implementation mode one
Please refer to fig. 2, which is a flowchart illustrating an uplink information transmission method according to an embodiment of the present invention. The method comprises the following steps:
s210, receiving first information and second information, wherein the first information is used for scheduling a Physical Uplink Shared Channel (PUSCH) to be transmitted on a first time domain resource, and the second information is used for scheduling a Physical Downlink Shared Channel (PDSCH) to be transmitted on a second time domain resource; optionally, the first information includes Downlink Control Information (DCI), and the second information includes DCI;
and S220, if the first time domain resource and the second time domain resource are overlapped, processing signal transmission according to a preset rule.
If the first time domain resource and the second time domain resource are overlapped, the terminal cannot transmit the PUSCH and receive the PDSCH at the same time, so that the terminal can only select one of the PUSCH transmission processing and the PDSCH transmission processing to process, and therefore a certain rule needs to be set to process such a conflict, so as to improve the reliability of data transmission.
Optionally, the processing signal transmission according to the preset rule in S220 includes:
s221, processing at least one of the PUSCH and the PDSCH according to the correlation time of the first information and the correlation time of the second information.
Wherein processing at least one of the PUSCH and the PDSCH comprises processing one of the PUSCH and the PDSCH.
Processing the PUSCH refers to performing transmission processing of the PUSCH on the resource, such as: the user equipment performs transmission processing on the resource, or the network equipment performs reception processing on the resource. Processing PDSCH refers to performing transmission processing of PDSCH on the resource, such as: the user equipment performs receiving processing on the resource, or the network equipment performs transmitting processing on the resource.
Wherein the relevant time of the first information comprises the receiving time of the first information or the sending time of the first information; and/or the relevant time of the second information comprises the receiving time of the second information or the sending time of the second information.
Referring to fig. 3 and fig. 4, a schematic diagram of resource scheduling performed by the first information and the second information in the first embodiment of the present application is shown. In fig. 3, the second information is received or sent first, and then the first information is received or sent, where resources indicated by the two information are overlapped in a time domain. In fig. 4, the first information is received or transmitted first, and then the second information is received or transmitted, where the resources indicated by the two information are overlapped in the time domain.
Optionally, S221 includes: processing at least one of the PUSCH and the PDSCH according to the transmission time of the first information and the transmission time of the second information.
For example: and processing the scheduling corresponding to the information with the earlier sending time in the first information and the second information. If the network equipment sends the first information first and then sends the second information, the scheduling corresponding to the first information is processed, namely the terminal processes the PUSCH; if the network device sends the second information first and then sends the first information, the scheduling corresponding to the second information is processed, that is, the terminal processes the PDSCH.
Another example is: and processing the scheduling corresponding to the information with the later sending time in the first information and the second information. If the network equipment sends the first information first and then sends the second information, the scheduling corresponding to the second information is processed, namely the terminal processes the PDSCH; and if the network equipment firstly sends the second information and then sends the second information to the first information, processing scheduling corresponding to the first information, namely processing the PUSCH by the terminal.
Optionally, S221 includes: processing at least one of the PUSCH and the PDSCH according to the reception time of the first information and the reception time of the second information.
For example: and processing the scheduling corresponding to the information with the earlier receiving time in the first information and the second information. If the terminal equipment receives the first information firstly and then receives the second information, processing scheduling corresponding to the first information, namely processing a PUSCH (physical uplink shared channel) by the terminal; if the terminal receives the second information first and then receives the first information, the terminal processes the scheduling corresponding to the second information, that is, processes the PDSCH of the implementation.
For another example: and processing the scheduling corresponding to the information with the later receiving time in the first information and the second information. If the terminal equipment receives the first information first and then receives the second information, processing scheduling corresponding to the second information, namely processing a PDSCH (physical Downlink shared channel) by the terminal; if the terminal receives the second information first and then receives the first information, the terminal processes the scheduling corresponding to the first information, that is, processes the PUSCH of the embodiment.
Optionally, the processing signal transmission according to the preset rule in S220 includes:
s222, processing at least one of the PUSCH and the PDSCH according to the priority of the traffic scheduled by the first information and the second information.
For example: if the priority of the service scheduled by the first information is higher than that of the service scheduled by the second information, processing the scheduling corresponding to the first information, namely processing a PUSCH by the terminal; and if the priority of the service scheduled by the second information is higher than that of the service scheduled by the first information, processing the scheduling corresponding to the first information, namely processing the PDSCH by the terminal.
Optionally, if the priority of the service scheduled by the first information is the same as the priority of the service scheduled by the second information, processing at least one of the PUSCH and the PDSCH according to the relevant time of receiving the first information and the relevant time of the second information. Processing the content of at least one of the PUSCH and the PDSCH according to the time of the first information and the second information with reference to the aforementioned S221, which is not repeated herein.
Optionally, the processing signal transmission according to the preset rule in S220 includes:
s223, appointing at least one of the PUSCH and the PDSCH according to a protocol.
Optionally, the scheduling corresponding to the first information is processed according to a protocol agreement, that is, when the protocol agreement agrees that the same time domain resource is scheduled uplink and downlink at the same time, the PUSCH is processed; or,
processing scheduling corresponding to the second information according to a protocol convention, namely processing a PDSCH when the same time domain resource is scheduled by an uplink and a downlink at the same time by the protocol convention; or,
processing at least one of the PUSCH and the PDSCH according to the priority of the format of the downlink control information DCI appointed by the protocol; such as: processing scheduling corresponding to information with high priority in the first information and the second information, namely, a protocol appoints priority of different DCI formats, and when the same time domain resources are scheduled by the different DCI formats, paging is carried out according to processing signals of the priority of the DCI formats; for example: the priority ordering agreed by the protocol is DCI format 0_0> DCI format 0_1> DCI format 1_0> DCI format 1_1, and when different DCI formats schedule the same time domain resource, the scheduling with the DCI format high priority is selected for processing according to the sequence; if the priorities are the same, processing is performed according to the time sequence or the priority of the scheduled service, which is not repeated herein.
Optionally, the processing signal transmission according to the preset rule in S220 includes:
s224, processing at least one of the PUSCH and the PDSCH according to the transmission time of the PUSCH and the transmission time of the PDSCH.
Optionally, processing scheduling with earlier transmission time in the PUSCH and the PDSCH; or processing the scheduling with later transmission time in the PUSCH and the PDSCH. Specifically, if the transmission time of the PUSCH is earlier than the transmission time of the PDSCH, the PUSCH is processed; or, if the transmission time of the PDSCH is earlier than the transmission time of the PUSCH, processing the PDSCH; or, if the transmission time of the PUSCH is earlier than the transmission time of the PDSCH, processing the PDSCH; and if the transmission time of the PDSCH is earlier than that of the PUSCH, processing the PUSCH.
Optionally, if the transmission time of the PUSCH is the same as the transmission time of the PDSCH, at least one of the PUSCH and the PDSCH is processed according to the relevant time of the first information and the relevant time of the second information, or according to the priority of a service scheduled by the first information and the second information, or according to a protocol convention.
Such as: in fig. 3, in the first scheduling 310, the PUSCH transmission time is earlier than the PDSCH transmission time, the scheduling corresponding to the first information is processed, that is, the PUSCH is processed; in the third scheduling 330, the PDSCH transmission time is earlier than the PUSCH transmission time, and then the scheduling corresponding to the second information is processed, that is, the PDSCH is processed.
The PUSCH transmission time in the second scheduling 320 is the same as the PDSCH transmission time, and the scheduling corresponding to the processing may be determined according to other rules as described above, for example, the scheduling corresponding to the information with the earlier transmission time in the first information and the second information, that is, the PDSCH is processed.
The four preset rules for processing signal transmission disclosed in the first embodiment of the present application can be used in combination, that is, when it cannot be determined which schedule should be processed according to one of the rules, at least another way can be adopted to assist the determination. Such as: when the transmission and/or reception times of the first information and the second information are the same, which scheduling should be processed may be determined according to one of priorities of the first information and the second information scheduling traffic, or protocol conventions, or transmission times of the PUSCH and the PDSCH.
In the first embodiment of the present application, when a first time domain resource indicated by first information for uplink scheduling and a second time domain resource indicated by second information for downlink scheduling overlap, signal transmission is processed according to a preset rule. Therefore, the blank that no clear regulation is made in the prior art is made up, the system is more complete, and the reliability of data transmission can be ensured. Specifically, if the terminal device processes the PUSCH, the network device may know that the PDSCH is not received, and may perform processing such as retransmission or rescheduling on the PDSCH as soon as possible, thereby ensuring data transmission reliability; if the PDSCH is processed, the network equipment can know that the PUSCH is not transmitted, and can perform retransmission scheduling or rescheduling and other processing on the PUSCH as soon as possible, so that the reliability of data transmission is ensured.
