Description

Information transmission method and terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information transmission method and a terminal.

Background

In a New Radio (NR) communication system of the fifth Generation mobile communication technology (5-Generation, 5G), a Physical Uplink Control CHannel (PUCCH) or a Physical Uplink Shared CHannel (PUSCH) may be transmitted from any one symbol in a Slot (Slot), and the transmission time length is not fixed, for example, the transmission time length may be 1 to 14 Orthogonal Frequency Division Multiplexing (OFDM) symbols. The current 5G NR communication system does not support simultaneous transmission of Information in the PUCCH, and when transmission times of Information to be transmitted in the PUCCH and the PUSCH collide, if starting positions of the PUCCH and the PUSCH are the same and transmission time lengths are the same, Uplink Control Information (UCI) in the PUCCH may be multiplexed on the PUSCH for transmission.

However, when the starting positions or the transmission time lengths of the transmissions of the PUCCH and the PUSCH are different, for example, when the starting position of the information to be transmitted in the PUCCH is later than the starting position of the information to be transmitted in the PUSCH, the UCI in the PUCCH may not be ready before the transmission of the information to be transmitted in the PUSCH starts, and thus the UCI cannot be multiplexed on the PUSCH for transmission.

Disclosure of Invention

The embodiment of the invention provides an information transmission method and a terminal, which are used for determining a transmission scheme according to the processing capability and/or the conflict condition of the terminal when the transmission time parts of a PUCCH and a PUSCH conflict.

When the transmission time parts of the information to be transmitted in the PUCCH and the PUSCH collide, the terminal can know how to determine how to perform subsequent transmission so as to ensure the accuracy of control information or data information transmission and ensure the communication quality of users.

Optionally, if the collision condition is that one or more PUCCHs collide with transmission time of information to be transmitted in the same PUSCH, the terminal determines, according to its processing capability and/or the collision condition, a transmission scheme of the PUCCH and the PUSCH, including:

When the transmission time of the transmission content in one or more PUCCHs and one PUSCH conflicts, the terminal can determine whether the terminal can multiplex all UCIs on the PUSCH, if so, the terminal multiplexes all the UCIs on the PUSCH for transmission, thus, the data information in the UCI and the PUSCH can be ensured to be transmitted completely, and the communication quality of a user is ensured.

When the UCI includes only CSI and the terminal cannot multiplex all CSI for transmission on the PUSCH, since CSI is transmitted once every other period, transmission of CSI information may be directly abandoned, or, if the terminal is also capable of multiplexing at least one CSI for transmission on the PUSCH, one of the CSI may be selected for transmission.

Optionally, if the UCI includes HARQ-ACK information and CSI, after the terminal determines whether UCI to be transmitted in all PUCCHs can be multiplexed on the PUSCH for transmission, the method further includes:

and if the terminal determines that UCI to be transmitted in all PUCCHs can be multiplexed on the PUSCH for transmission, determining all HARQ-ACK information included in the UCI, and determining that CSI with the highest priority in the UCI is multiplexed on the PUSCH for transmission.

and the terminal cascades the CSI included in the UCI according to the time sequence in the PUCCH and multiplexes the cascaded CSI on the PUSCH for transmission.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

The technical scheme provided by the embodiment of the invention is described below by combining the accompanying drawings.

Referring to fig. 1, an embodiment of the invention provides an information transmission method, and a flow of the method is described as follows.

S101: when the transmission time part of the information to be transmitted in the PUCCH and the PUSCH of the terminal conflicts, the terminal determines the transmission schemes of the PUCCH and the PUSCH according to the self processing capability and/or the conflict condition;

s102: and the terminal transmits the information to be transmitted in the PUCCH and/or the PUSCH according to the determined transmission scheme.

In the embodiment of the present invention, when a terminal sends UCI to a base station through a PUCCH, a situation may occur where the transmission time of the information to be transmitted in the PUCCH and the transmission time of the information to be transmitted in the PUSCH partially collide, that is, the transmission time of the UCI and the transmission time of the data information in the PUSCH overlap in a time domain, and since the current 5G NR communication system does not support simultaneous transmission of information through the PUCCH and the PUSCH, when the collision occurs, only one channel can be selected for transmission, and then the terminal may determine a transmission scheme for the collision according to its own processing capability and/or a collision situation.

In the embodiment of the present invention, when one or more PUCCHs collide with the transmission time of information to be transmitted in the same PUSCH, the content to be transmitted may be determined according to the content transmitted in the PUCCH and the processing capability of the terminal. The UCI transmitted in the PUCCH may include HARQ-ACK information, CSI, and a Scheduling Request (SR), but since the terminal does not send the SR to the base station when transmitting information through the PUSCH, only three cases that the UCI includes HARQ-ACK information and/or CSI need to be considered. The following description will be made separately for each case.

In the embodiment of the invention, when the UCI transmitted in the PUCCH only comprises HARQ-ACK information, the terminal can determine whether the HARQ-ACK information in all PUCCHs can be multiplexed on the PUSCH for transmission according to the processing capability of the terminal. Specifically, how the terminal determines whether to multiplex the HARQ-ACK information in the PUCCH on the PUSCH for transmission will be described later, which is not repeated herein.

Specifically, when the terminal determines that the HARQ-ACK information in all PUCCHs can be multiplexed on the PUSCH for transmission, the terminal can transmit the HARQ-ACK information in all PUCCHs on the PUSCH, so that the terminal can simultaneously complete the transmission of the HARQ-ACK information and the information to be transmitted in the PUSCH, namely, the conflict is solved, and the terminal can also ensure that all the information to be transmitted is not missed, thereby ensuring the integrity of control information and data information of a user and improving the reliability of a communication process of the user.

When the terminal multiplexes the HARQ-ACK information in all PUCCHs on the PUSCH for transmission, the terminal may cascade the HARQ-ACK information according to the time-domain sequence and multiplex the HARQ-ACK information on the PUSCH for transmission.

Specifically, when the terminal determines that HARQ-ACK information in all PUCCHs cannot be multiplexed on the PUSCH for transmission, but the HARQ-ACK information is important, if the HARQ-ACK information cannot be transmitted correctly, the communication process of the terminal may be greatly affected, and therefore transmission of the HARQ-ACK information needs to be considered preferentially, so when the terminal cannot multiplex HARQ-ACK information in all PUCCHs on the PUSCH for transmission, only the HARQ-ACK information in the PUCCH may be transmitted, and information to be transmitted in the PUSCH which conflicts with the HARQ-ACK information in the PUCCH may be discarded without transmission. In this way, the influence on the communication process of the terminal can be reduced.

In the embodiment of the present invention, when the following conditions are simultaneously satisfied, the terminal may determine that HARQ-ACK information in a PUCCH can be multiplexed on a PUSCH for transmission, where the conditions include:

the time difference between the end position of the information to be transmitted in the PDSCH and the start position of the HARQ-ACK information in the PUCCH is greater than or equal to the sum of the time of the terminal for generating the concatenated HARQ-ACK information and the time of 1 OFDM symbol;

the time difference from the ending position of the scheduling information in the Physical Downlink Control Channel (PDCCH) to the starting position of the information to be transmitted in the PUSCH is greater than or equal to the sum of the time for the terminal to generate the information to be transmitted in the PUSCH and the time of 1 OFDM symbol; wherein the scheduling information is used for scheduling the PUSCH.

If the two conditions cannot be satisfied simultaneously, the terminal cannot multiplex HARQ-ACK information in all PUCCHs on the PUSCH.

In the embodiment of the present invention, when the UCI transmitted in the PUCCH includes only CSI, the terminal may also determine whether CSI in all PUCCHs can be multiplexed on the PUSCH for transmission according to its own processing capability. Specifically, how the terminal determines whether to multiplex the CSI in the PUCCH on the PUSCH for transmission will be described later, which is not described herein again.

Specifically, when the terminal determines that the CSI in all PUCCHs can be multiplexed on the PUSCH for transmission, the terminal may multiplex all CSI on the PUSCH for transmission, so as to ensure that all CSI can be transmitted. Certainly, since the CSI is reported once every a period of time, in order to reduce the processing time of the terminal during multiplexing, only the last CSI in the transmission time may be reported, that is, the latest CSI is multiplexed and transmitted on the PUSCH; or only multiplexing and transmitting the CSI with the highest priority in all the CSI on the PUSCH. The priority of the CSI is related to the type of the CSI, for example, when the CSI comprises Semi-Persistent CSI (SP-CSI) and Periodic CSI (P-CSI), the priority of the SP-CSI can be higher than that of the P-CSI; or, the priority of the CSI is related to the transmission time of the PUCCH carrying the CSI, for example, when there are multiple CSI of the same type, the CSI with the most recent time may be used as the CSI with the higher priority.

When the terminal multiplexes the CSI in all PUCCHs on the PUSCH for transmission, the terminal may concatenate the CSI in time domain order and multiplex the CSI on the PUSCH for transmission.

Specifically, when the terminal determines that the CSI in all PUCCHs cannot be multiplexed on the PUSCH for transmission, the terminal selects to transmit only the information to be transmitted in the PUSCH, that is, to discard all CSI. If the terminal cannot multiplex the CSI in all PUCCHs on the PUSCH for transmission, but may multiplex one or more CSI on the PUSCH for transmission, the terminal may select the CSI with the last transmission time for multiplexing transmission on the PUSCH; or only multiplexing and transmitting the CSI with the highest priority in all the CSI on the PUSCH.

In the embodiment of the present invention, when the following conditions are simultaneously satisfied, the terminal may determine that CSI in the PUCCH can be multiplexed on the PUSCH for transmission, where the conditions include:

the time difference between the end position of the measurement resource of the CSI and the start position of the information to be transmitted in the PUSCH is greater than or equal to the time difference between the terminal and the CSI after the CSI measurement is completed and the generation of the cascade connection;

the time difference from the end position of the scheduling information in the PDCCH for transmitting the scheduling PUSCH to the start position of the information to be transmitted in the PUSCH is greater than or equal to the time for the terminal to generate the information to be transmitted in the PUSCH.

If the above two conditions cannot be satisfied simultaneously, the terminal cannot multiplex CSI in all PUCCHs on the PUSCH.

In the embodiment of the invention, when the UCI transmitted in the PUCCH simultaneously comprises the HARQ-ACK information and the CSI, the terminal can determine whether the HARQ-ACK information and the CSI in all the PUCCHs can be multiplexed on the PUSCH for transmission according to the processing capability of the terminal. Specifically, when the terminal simultaneously satisfies the conditions that all HARQ-ACK information can be multiplexed on the PUSCH and all CSI can be multiplexed on the PUSCH, it may be determined that the terminal can multiplex HARQ-ACK information and CSI in all PUCCHs on the PUSCH for transmission; if the terminal does not satisfy any of the conditions of multiplexing all HARQ-ACK information on the PUSCH and multiplexing all CSI on the PUSCH, it may be determined that the terminal cannot transmit the HARQ-ACK information and CSI in all PUCCHs multiplexed on the PUSCH.

Specifically, when the terminal determines that the HARQ-ACK information and CSI in all PUCCHs can be multiplexed on the PUSCH for transmission, the terminal may multiplex the HARQ-ACK information and CSI in all PUCCHs on the PUSCH for transmission. Or, in order to reduce the processing time of the terminal, the terminal may choose not to transmit all the CSI, and only multiplex one of the CSI on the PUSCH for transmission, and directly discard the rest of the CSI without transmission, that is, the terminal may multiplex all the HARQ-ACK information and the CSI with the last transmission time on the PUSCH for transmission; or, the terminal may multiplex all HARQ-ACK information and CSI with the highest priority for transmission on the PUSCH.

Specifically, when the terminal can multiplex HARQ-ACK information in all PUCCHs on the PUSCH for transmission, but cannot multiplex CSI in all PUCCHs on the PUSCH for transmission, the terminal may multiplex only all HARQ-ACK information on the PUSCH for transmission, and directly discard all CSI; or, the terminal may also discard the information to be transmitted in the PUSCH and only transmit the content in the PUCCH, that is, only transmit the HARQ-ACK information and CSI in all PUCCHs. If the terminal cannot multiplex the CSI in all PUCCHs on the PUSCH for transmission, but may multiplex one or more CSIs on the PUSCH for transmission, the terminal may select one of the CSIs to be multiplexed on the PUSCH together with all HARQ-ACK information for transmission. One of the CSIs may be, for example, a last transmission time CSI; or, the highest priority CSI.

Specifically, when the terminal cannot multiplex HARQ-ACK information in all PUCCHs for transmission on the PUSCH, in order to ensure transmission of the HARQ-ACK information, the terminal may directly discard information to be transmitted in the PUSCH, not transmit the information, and only transmit the information to be transmitted in the PUCCH.

In the embodiment of the invention, when one PUCCH conflicts with the transmission time of information to be transmitted in a plurality of PUSCHs, the processing capability of the terminal can completely multiplex UCI in the PUCCH on the PUSCH for transmission in the case, so that the terminal can select one PUSCH in the plurality of PUSCHs to carry UCI in the PUCCH for transmission. Specifically, in order to ensure sufficient processing time for the terminal, one of the PUSCHs may be, for example, the PUSCH with the most late transmission time.

Specifically, when the UCI includes HARQ-ACK information, the terminal may select one of the PUSCHs to carry the UCI in the PUCCH for transmission, where one of the PUSCHs may also be the PUSCH with the most late transmission time; however, when the UCI does not include HARQ-ACK information, for example, only includes CSI, the terminal may also transmit only information to be transmitted in the PUSCH, and directly drop CSI without transmission.

In the embodiment of the invention, when the terminal determines that the information to be transmitted in one channel needs to be discarded, the terminal does not transmit any information in the channel after determining that the information needs to be discarded, and further can stop preparing the information needing to be transmitted in the channel after determining that the information needs to be discarded. For example, after the PUCCH and the PUSCH collide, HARQ-ACK information is transmitted in the PUCCH, and when the terminal receives scheduling information of the PUSCH and downlink data transmission corresponding to the PUCCH, the terminal can determine that the PUSCH needs to be discarded, and then stop processing data that needs to be transmitted on the PUSCH, for example, stop a process such as encoding, and transmit only HARQ-ACK information on the PUCCH channel. If the terminal determines that the content in the PUSCH needs to be discarded after the terminal starts to transmit the scheduling information on the PUSCH, the terminal immediately stops transmitting the scheduling information in the PUSCH and does not continue to transmit the rest scheduling information to reduce the influence on other users.

In the embodiment of the invention, the CSI mentioned above can be P-CSI or SP-CSI information.

In the embodiment of the invention, when the UCI is multiplexed in the PUSCH for transmission, the UCI can be mapped to the PUSCH for transmission according to the preset mapping rule. For example, the mapping rule may be that the HARQ-ACK information is mapped after a first Demodulation Reference Signal (DMRS) symbol according to an order of frequency domain first and time domain second; if the CSI includes a CSI part (part)1 and a CSI part 2, the CSI part 1 and the CSI part 2 may be mapped from a first available Resource Element (RE) according to a frequency domain before time domain manner. Wherein, if the REs occupied by UCI do not occupy all of one OFDM symbol, or the number of OFDM symbols included in the REs occupied by UCI is greater than one OFDM symbol, but the REs on all PUSCH bandwidths are not occupied on the last OFDM symbol, the mapping is an average discrete mapping in the frequency domain. For example, when UCI does not occupy all of one OFDM symbol, the frequency domain interval is rounded down by the ratio of the number of REs available on that OFDM symbol to the number of remaining unmapped UCI symbols. Since the mapping rule belongs to the category of the prior art, it is not described in detail, and certainly, the UCI may be mapped by other possible mapping rules besides the above mapping rule.

In the embodiment of the present invention, after the terminal determines the transmission scheme when the transmission times of the PUCCH and the PUSCH collide according to the above various situations, the terminal may transmit information according to the determined transmission scheme. The specific transmission content is already described in the process of determining the scheme, and is not described herein again.

The above-described technical solutions will be described below with specific examples.

Referring to fig. 2, in the 5G-NR communication system, a feedback period of CSI configured by a base station for a terminal through Radio Resource Control (RRC) signaling is 5 slots, and a time domain Resource of a PUCCH used by the CSI is the last 3 OFDM symbols in one Slot, for example, in fig. 2, the terminal feeds back CSI on the last 3 OFDM symbols in the nth Slot, the n +5 Slot, and the n +10 Slot, respectively. In fig. 2, the time trend is that the time of the nth +1 Slot is later than that of the nth Slot, the time of the nth +2 Slot is later than that of the nth +1 Slot, and so on.

The base station schedules a PUSCH based on the Slot transmission in the n +1 th Slot and the n +8 th Slot, and schedules a PDSCH based on the mini-Slot transmission in the n +2 th Slot, the n +4 th Slot and the n +9 th Slot. The PUSCH based on the Slot transmission occupies the time of one whole Slot, namely occupies 14 OFDM symbols, and the PDSCH based on the mini-Slot transmission can occupy 1-14 OFDM symbols in one Slot. Correspondingly, for each PDSCH, the terminal feeds back corresponding HARQ-ACK information to the base station, for example, as shown in fig. 2, HARQ-ACK information corresponding to the PDSCH of the n +1 Slot is on the second PUCCH in the n +3 slots, i.e., the PUCCH that is later in time, HARQ-ACK information corresponding to the PDSCH of the n +2 slots is on the first PUCCH in the n +3 slots, HARQ-ACK information corresponding to the PDSCH of the n +4 slots is on the PUCCH resource in the n +5 slots, HARQ-ACK information corresponding to the PDSCH of the n +8 slots is on the first PUCCH in the n +10 slots, HARQ-ACK information corresponding to the PDSCH of the n +9 slots is on the second PUCCH in the n +10 slots, since the CSI may be transmitted simultaneously on the transmission time of the second PUCCH in the n +9 th Slot, that is, the HARQ-ACK information and the CSI may be transmitted in the same PUCCH on the last three symbols.

It should be noted that the resource allocation shown in fig. 2 is only the allocation in the time domain, for example, in the nth Slot, the transmission of the PUSCH indicated by the right-oblique line is only used to illustrate that the PUSCH occupies all OFDM symbols in this Slot, but there may be any resource allocation in the frequency domain and is not used to indicate that the PUSCH occupies half of the frequency domain resources.

As can be seen from fig. 2, the transmission times of information to be transmitted in the PUSCH and PUCCH in the nth Slot, the n +3 th Slot, the n +5 th Slot, and the n +10 th Slot collide, and the collision of each Slot will be specifically described below.

For the nth Slot, the information to be transmitted in the PUCCH includes only CSI, that is, at an OFDM symbol occupied by an orthorhombic block, the terminal may determine whether there is enough processing time to multiplex the CSI on the PUSCH for transmission, and if the determination result is yes, the terminal may transmit the CSI on the PUSCH sub-at the nth Slot; or, if the determination result is no, the terminal may not transmit the CSI at the nth Slot, and only transmit information to be transmitted in the PUSCH.

For the n +3 slots, the information to be transmitted in the two PUCCHs colliding with the PUSCH comprises only HARQ-ACK information, and similarly, the terminal may first determine whether sufficient processing time is available to multiplex the two HARQ-ACK information on the PUSCH for transmission, and if the determination result is yes, the terminal may multiplex the two HARQ-ACK information on the PUSCH for transmission when the n +3 slots are available; or, if the determination result is negative, the terminal may discard the information to be transmitted in the PUSCH and not transmit the information, but only transmit the HARQ-ACK information in the two PUCCHs, in order to ensure that the HARQ-ACK information can be transmitted by the terminal in the n +3 Slot.

Specifically, when the HARQ-ACK information is multiplexed on the PUSCH for transmission, when the terminal generates the HARQ-ACK information, the terminal may cascade the HARQ-ACK information on the two PUCCHs according to a time sequence, where the HARQ-ACK information carried by the PUCCH at the time domain position before and the HARQ-ACK information carried by the PUCCH at the time domain position after.

For the n +5 Slot, of the two PUCCHs colliding with the PUSCH, the former PUCCH only comprises HARQ-ACK information, the latter PUCCH only comprises CSI, and likewise, the terminal can firstly determine whether enough processing time is available for multiplexing the HARQ-ACK information and the CSI on the PUSCH for transmission, and if the determination result is positive, the terminal can multiplex the HARQ-ACK information and the CSI on the PUSCH for transmission when the n +5 Slot is available; or, if the determination result indicates that the terminal has enough processing time to multiplex the HARQ-ACK information on the PUSCH for transmission, but does not have enough processing time to multiplex the CSI on the PUSCH for transmission, the terminal may multiplex the HARQ-ACK information on the PUSCH for transmission, and discard the CSI information for non-transmission, at the n +5 Slot; or, if the determination result indicates that the terminal cannot multiplex the HARQ-ACK information and the CSI on the PUSCH for transmission, the terminal may discard the information to be transmitted in the PUSCH and not transmit the information, but only transmit the HARQ-ACK information and the CSI in the PUCCH, at the n +5 Slot.

For the n +10 Slot, of the two PUCCHs colliding with the PUSCH, the former PUCCH includes only HARQ-ACK information, and the latter PUCCH includes both HARQ-ACK information and CSI, if the terminal determines that UCI in the two PUCCHs can be multiplexed on the PUSCH for transmission, the terminal may multiplex UCI in the two PUCCHs on the PUSCH for transmission at the n +10 Slot; or when the terminal cannot multiplex the HARQ-ACK information in any PUCCH on the PUSCH for transmission, the terminal can abandon the information to be transmitted in the PUSCH for transmission and only transmit the HARQ-ACK information and CSI in the PUCCH when the n +10 Slot is in the nth Slot; or, the terminal may multiplex the HARQ-ACK information in the two PUCCHs on the PUSCH for transmission, but if there is not enough processing time to multiplex the CSI on the PUSCH for transmission, then at the n +10 Slot, the terminal may multiplex the HARQ-ACK information in the two PUCCHs on the PUSCH for transmission, and discard the CSI for transmission. For the processing manner when the two HARQ-ACK information are multiplexed, refer to the description in the n +3 Slot, and are not described herein again.

Referring to fig. 3, in the 5G-NR communication system, a feedback period of CSI configured by a base station for a terminal through RRC signaling is 5 slots, and a time domain resource of a PUCCH used by the CSI is one Slot, for example, in fig. 3, the terminal feeds back CSI on an nth Slot, an n +5 Slot, and an n +10 Slot, respectively. In fig. 3, the time trend is that the time of the nth +1 Slot is later than that of the nth Slot, the time of the nth +2 Slot is later than that of the nth +1 Slot, and so on.

The base station schedules a PUSCH based on mini-Slot transmission in the n +1 th Slot and the n +5 th Slot, schedules a PDSCH based on mini-Slot transmission in the n +3 th Slot, and positions of HARQ-ACK information corresponding to the PDSCH are on the n +5 th Slot, namely the PUCCH on the n +5 th Slot simultaneously comprises the HARQ-ACK information and CSI.

Note that the resource allocation shown in fig. 3 is also only the allocation in the time domain, and is not used to show the allocation in the frequency domain.

As can be seen from fig. 2, the transmission times of the information to be transmitted in the PUSCH and the PUCCH in the nth Slot and the n +5 th Slot collide, and the collision of each Slot will be specifically described below.

For the nth Slot, only the CSI is included in the PUCCH which conflicts with the transmission time of the PUSCH, and the terminal can abandon the CSI for not transmitting but directly transmit the information to be transmitted in the PUSCH; or, the terminal may multiplex the CSI on the PUSCH in the nth Slot at a later time for transmission.

For the (n + 5) th Slot, the PUCCH which conflicts with the transmission time of the PUSCH comprises HARQ-ACK information and CSI, and the terminal can multiplex the corresponding HARQ-ACK information and CSI information on the PUSCH with the later time in the (n + 5) th Slot for transmission; or, the terminal may also choose to transmit only HARQ-ACK information and CSI in the PUCCH, and discard all contents to be transmitted in the two PUSCHs without transmission.

In summary, in the embodiments of the present invention, when the transmission time of the PUCCH and the transmission time of the PUSCH collide with each other, the terminal can determine the subsequent transmission scheme according to the processing capability of the terminal, the priority of the transmission content, the collision condition, and other factors, thereby ensuring that the control information and the data information in the 5G NR communication system can be correctly transmitted, so that the communication process is correctly performed, and improving the reliability of the 5G NR communication system.
