Description

Transmission method of uplink control information UCI, user terminal and base station

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a transmission method of a UCI, a user terminal, and a base station.

Background

With the development of mobile communication service demand, several organizations such as International Telecommunications Union (ITU) have started to research a New wireless communication system, i.e., a 5G New Radio (NR) communication system.

For the same ue, in order to avoid an excessive Peak-to-average power Ratio (PARR), simultaneous transmission of uplink channels or signals is not supported in the 5G NR communication system, and therefore, when resources of the uplink channels or signals overlap, a specific transmission rule for multiplexing or discarding information needs to be defined to ensure that the ue only transmits one uplink channel or signal at the same time. Since some channels or signals need to be discarded when resources of the uplink channels or signals overlap, many manufacturers of the user terminals do not want to find that the channels need to be discarded when half of the channels are found in the process of transmitting one uplink channel by the user terminal, and thus, a timeline requirement is defined for uplink channel collision.

Generally, when resources of a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH) are overlapped, a user terminal may multiplex UCI carried by the PUCCH on the PUSCH to transmit the UCI while satisfying a timeline requirement.

It should be noted that, in the current 5G NR communication system, if the single-slot PUCCH and the multi-slot PUSCH overlap in time, according to the current specification, UCI carried by the single-slot PUCCH is likely to be transferred to a partial slot of the multi-slot PUSCH for transmission, which may result in degradation of UCI transmission performance.

In the first processing strategy, the user terminal may transfer UCI carried by the single-slot PUCCH to each slot of the multi-slot PUSCH for transmission, and discard the single-slot PUCCH, so that the UCI is no longer transmitted in the single-slot PUCCH, but is multiplexed to be transmitted in each slot of the multi-slot PUSCH, which can effectively avoid uplink channel collision, and compared with the case where only part of the slots of the multi-slot PUSCH are multiplexed to be transmitted in the prior art, which can also effectively ensure the transmission performance of the UCI. In the second processing strategy, the ue may continue to transmit UCI on the single-slot PUCCH and discard the time slot overlapping with the single-slot PUCCH in the multi-slot PUSCH, so as to effectively avoid uplink channel collision, and the transmission performance of UCI is not affected, so that the transmission performance of UCI can be effectively ensured compared with the case of multiplexing only part of the time slots of the multi-slot PUSCH for transmission in the prior art.

It can be seen that, for the case that the single-slot PUCCH and the multi-slot PUSCH are at least partially overlapped in time, no matter what processing strategy is adopted, compared with the prior art, the embodiment of the present invention can effectively ensure the transmission performance of UCI on the premise of ensuring that no uplink channel collision occurs.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

Referring to fig. 1, a transmission method of UCI according to an embodiment of the present invention is shown. As shown in fig. 1, the method is applied to a user terminal, and includes the following steps:

step 101, aiming at a single-slot PUCCH, determining whether a multi-slot PUSCH at least partially overlapping with the single-slot PUCCH in time exists; if there is a multi-slot PUSCH at least partially overlapping in time with the single-slot PUCCH, step 102 is performed.

It should be noted that the user terminal specifically executes the subsequent step 102 when there is a multi-slot PUSCH at least partially overlapping with the single-slot PUCCH in time, and both the single-slot PUCCH and the multi-slot PUSCH meet the timeline requirement.

102, transferring UCI carried by a single-slot PUCCH to each slot of a multi-slot PUSCH for transmission, and discarding the single-slot PUCCH; or transmitting UCI carried by the single-slot PUCCH and discarding the time slot which is overlapped with the single-slot PUCCH in the multi-slot PUSCH.

The slot may also be indicated by slot.

In step 102, when the user terminal transfers UCI carried by the single-slot PUCCH to each slot of the multi-slot PUSCH for transmission (in this case, the slot PUSCH may be regarded as a whole), the UCI may be transmitted repeatedly in each slot of the multi-slot PUSCH, or the UCI may be transmitted in each slot of the multi-slot PUSCH in a rate-matched manner. Here, the repeated transmission refers to that UCI is encoded according to Resource Elements (REs) used for UCI transmission in a first slot of a multi-slot PUSCH, and is repeatedly transmitted in a subsequent slot; the rate matching transmission means that UCI is encoded according to REs used for UCI transmission in all time slots of a multi-slot PUSCH, and encoding bits are mapped to all time slots of the multi-slot PUSCH.

It should be noted that the number of multi-slot PUSCHs at least partially overlapping with a single-slot PUCCH in time may be one or more. It should be noted that "a plurality" in this paragraph and "a plurality" referred to in the following embodiments each mean at least two.

Optionally, if there are multiple multi-slot PUSCHs and single-slot PUCCHs at least partially overlapping in time;

transferring UCI carried by a single-slot PUCCH to each slot of a multi-slot PUSCH for transmission, and the method comprises the following steps:

transferring UCI carried by a single-slot PUCCH into a plurality of multi-slot PUSCHs, wherein the first (namely the first) multi-slot PUSCHs at least partially overlapped with the single-slot PUCCH in time are transmitted in each slot of the multi-slot PUSCHs;

alternatively, the first and second electrodes may be,

transferring UCI carried by a single-slot PUCCH to a plurality of multi-slot PUSCHs, wherein the initial position of the UCI is earlier than or equal to that of each slot of the multi-slot PUSCHs of the single-slot PUCCH for transmission;

alternatively, the first and second electrodes may be,

and transferring UCI carried by the single-slot PUCCH to a plurality of multi-slot PUSCHs, wherein the first starting position is later than or equal to each slot of the multi-slot PUSCH of the single-slot PUCCH for transmission.

In this embodiment, if there is a plurality of multi-slot PUSCHs and a single-slot PUCCH at least partially overlapping in time, the user terminal may select the multi-slot PUSCH in a certain manner, and transfer UCI carried by the single-slot PUCCH to each slot of the selected multi-slot PUSCH for transmission.

Specifically, in the first mode, the user terminal transfers UCI carried by the single-slot PUCCH to each slot of the first multi-slot PUSCH that at least partially overlaps with the single-slot PUCCH in time for transmission, and discards the single-slot PUCCH.

As can be seen, in the first mode, the user terminal selects the multi-slot PUSCH for transmitting UCI based on the precedence order at least partially overlapping with the single-slot PUCCH in time.

In the second mode, the ue may determine whether there is a multi-slot PUSCH with a starting position earlier than or equal to that of the single-slot PUCCH in the multiple multi-slot PUSCHs. If a multi-slot PUSCH with the starting position earlier than or equal to the starting position of the single-slot PUCCH exists, the user terminal can transfer UCI carried by the single-slot PUCCH to each slot of the multi-slot PUSCH with the starting position earlier than or equal to the single-slot PUCCH for transmission, and discards the single-slot PUCCH; otherwise, the user terminal may discard the time slot overlapping with the single-slot PUCCH in the multiple multi-slot PUSCH, and the UCI is still transmitted on the single-slot PUCCH.

As can be seen, in the second mode, the user terminal selects the multi-slot PUSCH for transmitting UCI based on the morning and evening of the starting position.

In the third mode, the user terminal may determine whether there is a multi-slot PUSCH whose starting position is later than or equal to the starting position of the single-slot PUCCH, among the multiple multi-slot PUSCHs. If a multi-slot PUSCH with the starting position later than or equal to the starting position of the single-slot PUCCH exists, the user terminal can transfer UCI carried by the single-slot PUCCH to each slot of the multi-slot PUSCH with the first starting position later than or equal to the single-slot PUCCH for transmission, and discards the single-slot PUCCH; otherwise, the user terminal may discard the time slot overlapping with the single-slot PUCCH in the multiple multi-slot PUSCH, and the UCI is still transmitted on the single-slot PUCCH.

As can be seen, in the third mode, the user terminal also selects the multi-slot PUSCH for transmitting UCI based on the morning and evening of the starting position.

As can be seen from the above first to third modes, for the case where a plurality of multi-slot PUSCHs and a single-slot PUCCH are at least partially overlapped in time, based on the sequence of at least partially overlapping the single-slot PUCCH in time or the morning and evening of the start position, the user terminal can very conveniently select the multi-slot PUSCH for transmitting UCI.

Optionally, if there is a multi-slot PUSCH at least partially overlapping with the single-slot PUCCH in time, transferring UCI carried by the single-slot PUCCH to each slot of the multi-slot PUSCH for transmission, including:

if at least two carriers in a plurality of carriers configured by a user terminal have PUSCHs which are at least partially overlapped with a single-slot PUCCH in time, selecting one carrier from the at least two carriers;

and transferring UCI carried by the single-slot PUCCH to the selected carrier, and transmitting in each slot of the PUSCH at least partially overlapping with the single-slot PUCCH in time.

The total number of carriers configured by the ue may be two carriers shown in fig. 2 to fig. 3 and fig. 5 to fig. 8, or four carriers shown in fig. 4, and of course, the total number of carriers configured by the ue is not limited thereto, and may be determined specifically according to an actual situation, which is not limited in this embodiment.

In this embodiment, if there is a PUSCH which at least partially overlaps with a single slot PUCCH in time on at least two carriers, the user terminal may first select one carrier from the at least two carriers. It should be noted that, the specific implementation form of selecting one carrier from at least two carriers is various, and the following description is made by way of example.

In a first implementation form, selecting one carrier from at least two carriers includes:

and preferentially selecting the carrier with the least repeated times of the corresponding multislot PUSCH from at least two carriers.

It can be seen that, in the first implementation form, based on the number of times of the corresponding multi-slot PUSCH repetition, the user terminal may very conveniently select one carrier from at least two carriers.

In a second implementation form, selecting one carrier from at least two carriers includes:

and preferentially selecting the carrier with the same starting position of the corresponding multislot PUSCH and the single-slot PUCCH from at least two carriers.

It can be seen that, in the second implementation form, based on the corresponding multi-slot PUSCH starting position, the user terminal may very conveniently select one carrier from at least two carriers.

In a third implementation form, selecting one carrier from at least two carriers includes:

preferentially selecting a carrier with a corresponding multislot PUSCH starting position earlier than or equal to a single-slot PUCCH starting position from at least two carriers;

alternatively, the first and second electrodes may be,

and preferentially selecting the carrier with the starting position of the corresponding multislot PUSCH equal to or later than the starting position of the single-slot PUCCH from at least two carriers.

It can be seen that, in the third implementation form, based on the corresponding multi-slot PUSCH starting position, the user terminal may also very conveniently select one carrier from at least two carriers.

Regardless of the implementation form, after selecting one carrier from at least two carriers, the user terminal may transfer UCI carried by the single-slot PUCCH to the selected carrier, and transmit in each slot of the PUSCH at least partially overlapping in time with the single-slot PUCCH.

It should be noted that if there is only one PUSCH on the selected carrier, which at least partially overlaps with the single-slot PUCCH in time, the user terminal may directly transfer UCI carried by the single-slot PUCCH to each slot of the PUSCH for transmission. If there are a plurality of PUSCHs on the selected carrier that at least partially overlap with the single-slot PUCCH in time, the user terminal may select a PUSCH for transmitting UCI from the plurality of PUSCHs on the selected carrier according to a set rule.

It can be seen that, in this embodiment, for the case that there are PUSCHs that are at least partially overlapped with a single-slot PUCCH in time on at least two carriers, the user terminal may first select the carrier and then select the PUSCH, so as to determine the PUSCH for transmitting UCI more conveniently.

It should be noted that in the prior art, a situation that the single-slot PUCCH and a plurality of single-slot PUSCHs at least partially overlap in time, and a situation that the single-slot PUCCH and a multi-slot PUSCH at least partially overlap in time may occur. For the case that a single-slot PUCCH and multiple single-slot PUSCHs are at least partially overlapped in time, in the prior art, a user terminal may select a single-slot PUSCH according to a certain priority rule, and transfer UCI carried by the single-slot PUCCH to the selected single-slot PUSCH for transmission.

Specifically, the first rule specifies that, if a single-slot PUSCH for transmitting a-Channel State Information (CSI) is included in the plurality of single-slot PUSCHs, the single-slot PUSCH for transmitting the a-CSI is preferentially selected.

The second rule specifies that, if a single-slot PUSCH having a corresponding Physical Downlink Control Channel (PDCCH) and a single-slot PUSCH not having a corresponding PDCCH coexist in the plurality of single-slot PUSCHs, the single-slot PUSCH having the corresponding PDCCH is preferentially selected.

The third rule specifies that if there are multiple single-slot PUSCHs satisfying the second rule, the selection is performed according to the number sequence of the carriers where the single-slot PUSCHs are located, for example, the single-slot PUSCH on the carrier with the smaller number is preferentially selected.

The fourth rule states that if multiple time division multiplexed single slot PUSCHs overlap the same single slot PUCCH on the same carrier, the single slot PUSCH with the earliest starting transmission symbol is preferentially selected.

In addition, in the prior art, for the case that the single-slot PUCCH and the multi-slot PUSCH at least partially overlap in time, in the overlapping slots, it is specifically determined how to place UCI on the multi-slot PUSCH for transmission according to the overlapping case of the single-slot PUCCH and the single-slot PUSCH. Specifically, if the subcarrier interval configurations of the single-slot PUCCH and the multi-slot PUSCH are the same, the UCI carried by the single-slot PUSCH is transferred to the slot of the multi-slot PUSCH at least partially overlapped with the UCI for transmission; if the subcarrier spacing configurations of the single-slot PUCCH and the multi-slot PUSCH are different, UCI carried by the single-slot PUCCH is transferred to one or more PUSCH slots overlapped with the single-slot PUCCH for transmission, and the reduction of the transmission performance of the UCI often occurs in the situation.

Optionally, if there are multiple single-slot PUCCHs and multi-slot PUSCH at least partially overlapping in time;

transmitting UCI carried by a single-slot PUCCH and discarding a slot which overlaps with the single-slot PUCCH in time in a multi-slot PUSCH, wherein the method comprises the following steps:

In this embodiment, for the case where multiple single-slot PUCCHs and multi-slot PUSCHs overlap at least partially in time, the user terminal may directly discard the multi-slot PUSCH transmission and only transmit multiple single-slot PUCCHs, so that UCI transmission can be conveniently achieved, and uplink channel collision can be effectively avoided.

transferring UCI carried by a single-slot PUCCH to each slot of a multi-slot PUSCH for transmission, and discarding the single-slot PUCCH, wherein the method comprises the following steps:

and transferring UCI carried by a plurality of single-slot PUCCHs to each slot of a multi-slot PUSCH for transmission, and discarding the plurality of single-slot PUCCHs.

It should be noted that there are many cases of UCI carried by multiple single-slot PUCCHs, which is described as an example below.

In the first case, the UCI carried by the multiple single-slot PUCCHs is the UCI carried by the first single-slot PUCCH that at least partially overlaps in time with the multi-slot PUSCH.

In the second case, the UCI carried by the multiple single-slot PUCCHs is the highest priority UCI among the UCIs carried by the multiple single-slot PUCCHs.

Specifically, it is assumed that the multiple single-slot PUCCHs only include two single-slot PUCCHs, where UCI carried by one single-slot PUCCH is CSI, UCI carried by another single-slot PUCCH is a hybrid automatic Repeat Request Acknowledgement (HARQ-ACK) codebook, and since the priority of the HARQ-ACK codebook is higher than that of the CSI, UCI carried by the multiple single-slot PUCCHs is the HARQ-ACK codebook.

In a third case, the UCI carried by the plurality of single-slot PUCCHs is all of the UCI carried by the plurality of single-slot PUCCHs.

Specifically, in the third case, transferring UCI carried by multiple single-slot PUCCHs to each slot of a multi-slot PUSCH for transmission includes:

in UCI carried by a plurality of single-slot PUCCHs, the UCI of the same type is transferred to each slot of a multi-slot PUSCH for transmission after being cascaded and jointly coded;

alternatively, the first and second electrodes may be,

in UCI carried by a plurality of single-slot PUCCHs, the UCI of the same type is independently coded and then is respectively mapped on different resources in each slot of a multi-slot PUSCH for transmission.

It should be noted that, for the case that a plurality of single-slot PUCCHs and a multi-slot PUSCH at least partially overlap in time, assuming that based on the early and late of the starting position (or other determination rules), the user terminal determines that UCI carried by each single-slot PUCCH needs to be transferred to the multi-slot PUSCH for transmission, and at this time, the user terminal may determine how to perform UCI transmission according to one of the following rules (i.e., rule one to rule four).

Specifically, rule one specifies that multi-slot PUSCH transmissions are dropped and only a plurality of single-slot PUCCHs are transmitted.

Rule two specifies that UCI carried by the first single-slot PUCCH that overlaps at least partially in time with the multi-slot PUSCH is put on the multi-slot PUSCH for multiplexed transmission, and all single-slot PUCCHs overlapping with the multi-slot PUSCH are discarded.

Rule three specifies that the UCI with the highest priority among UCI carried by a plurality of single-slot PUCCHs is put on a multi-slot PUSCH for multiplexing transmission, and all single-slot PUCCHs overlapped with the multi-slot PUSCH are discarded.

Rule four specifies that all UCI carried by multiple single-slot PUCCHs are put together on a multi-slot PUSCH for multiplexing transmission, and all single-slot PUCCHs overlapped with the multi-slot PUSCH are discarded.

It should be noted that the rules one to four can be used in combination with the ways one to three. Among them, the preferred choices are as follows: rule one is used in combination with any of ways one through three; alternatively, rule two or rule three or rule four may be used in combination.

It can be seen that, in this embodiment, no matter which rule of the first to fourth rules is adopted, the ue can conveniently implement UCI transmission.

Optionally, the method further comprises:

In this embodiment, for a single-slot PUCCH, a user terminal may determine whether there is a multi-slot PUSCH and a single-slot PUSCH that at least partially overlap with the single-slot PUCCH in terms of time.

If the determination result is that the multi-slot PUSCH and the single slot at least partially overlapping with the multi-slot PUSCH in time exist at the same time, the user terminal can preferentially select the single-slot PUSCH to carry UCI and discard the single-slot PUCCH.

If the determination result is that only multi-slot PUSCHs at least partially overlapping in time exist, the user terminal can transfer UCI carried by the single-slot PUSCH to each slot of the multi-slot PUSCH for transmission.

It can be seen that, in this embodiment, regardless of whether there is a single-slot PUSCH at least partially overlapping with a single-slot PUCCH in time, the user terminal can conveniently implement transmission of UCI.

The following three examples are provided to illustrate the specific implementation process of the present solution in detail.

Example 1:

as shown in fig. 2 to fig. 3, the base station configures two carriers for the user terminal, where the subcarrier spacing of carrier 1 is configured to be 15kHz, the subcarrier spacing of carrier 2 is configured to be 60kHz, and carrier 1 is a transmission carrier of PUCCH, and the base station configures multi-slot PUSCH transmission with repetition number of 4 on carrier 2. When there is a PUCCH transmission in slot n of carrier 1, if at the same time the base station schedules a multi-slot PUSCH in slots 4n +2, 4n +3, 4n +4, 4n +5 of carrier 2, then,

if the above-mentioned first method is used, as shown in fig. 2, UCI carried by PUCCH in carrier 1 is transferred to slots 4n +2, 4n +3, 4n +4, 4n +5 of carrier 2 for multiplexing transmission on PUSCH, and PUCCH is discarded;

if the second method is used, as shown in fig. 3, since there is no multi-slot PUSCH with a starting position earlier than or equal to that of the PUCCH, the PUSCH transmission in slots 4n +2 and 4n +3 on carrier 2 is dropped, and UCI is still transmitted in the PUCCH of carrier 1;

if the third mode is used, the selection result is the same as that of the first mode.

Assuming that the first method is used in this embodiment, UCI is multiplexed and transmitted in PUSCH of slots 4n +2, 4n +3, 4n +4, and 4n +5 of carrier 2, assuming that PUCCH carries 5 bits of HARQ-ACK information, UCI is modulated on PUSCH by Quadrature Phase Shift Keying (QPSK), PUSCH is single-layer transmission, and the number of REs available for UCI transmission in PUSCH of slots 4n +2, 4n +3, 4n +4, and 4n +5 of carrier 2 is 50, then:

when the repeated transmission is used, the user terminal encodes 5-bit HARQ-ACK information into 100 bits, modulates and generates 50 modulation symbols, and repeatedly transmits the 50 modulation symbol information in the PUSCH of the time slots 4n +2, 4n +3, 4n +4 and 4n +5 of the carrier 2;

when the transmission is performed by the rate matching method, the user terminal encodes 5-bit HARQ-ACK information into 400 bits, generates 200 modulation symbols by modulation, and transmits the 200 modulation symbols in REs corresponding to 200 UCI information included in the PUSCH of 4n +2, 4n +3, 4n +4, and 4n +5 of the carrier 2.

Example 2:

as shown in fig. 4, the base station configures four carriers for the user equipment, where the subcarrier interval of carrier 1 is configured to be 15kHz, the subcarrier interval configurations of carrier 2, carrier 3, and carrier 4 are all 60kHz, carrier 1 is a transmission carrier of PUCCH, the base station configures multi-slot PUSCH transmission with repetition times of 4 on carriers 2 and 3, and single-slot PUSCH transmission on carrier 4. When there is PUCCH transmission in slot n of carrier 1, if the base station schedules a multi-slot PUSCH in slots 4n +2, 4n +3, 4n +4, 4n +5 of carrier 2, schedules a multi-slot PUSCH in slots 4n, 4n +1, 4n +2, 4n +3 of carrier 3, and schedules a single-slot PUSCH in slots 4n, 4n +1, 4n +2, 4n +3 of carrier 4, respectively, at the same time, the user terminal preferentially selects the PUSCH for single-slot transmission and multiplexes UCI on the PUSCH in slot 4n on carrier 4 for transmission.

In this embodiment, it is assumed that the base station does not configure carrier 4 for the ue, and only configures carrier 1, carrier 2, and carrier 3 for use, and the rest of the configuration is the same as described above. The user terminal may preferentially select the multi-slot PUSCH with the same transmission position of the multi-slot PUSCH and the PUCCH starting position to carry the UCI information, that is, select the multi-slot PUSCH in the carrier 3 to transmit the UCI information.

Example 3:

as shown in fig. 5 to 8, the base station configures two carriers for the user terminal, where the subcarrier spacing of carrier 1 is configured to be 15kHz, the subcarrier spacing of carrier 2 is configured to be 60kHz, carrier 1 is a transmission carrier of PUCCH, and the base station configures multi-slot PUSCH transmission with repetition number of 4 on carrier 2. When there is PUCCH transmission in slot n and slot n +1 of carrier 1, if the base station schedules multi-slot PUSCH transmission in slots 4n +2, 4n +3, 4n +4, 4n +5 on carrier 2 at the same time, there are several different results as follows:

using rule one above, as shown in fig. 5, the multi-slot PUSCH transmission on carrier 2 is discarded, and only the PUCCH in slot n and slot n +1 of carrier 1 is transmitted;

when the second rule is used, as shown in fig. 6, the UCI information carried by the first PUCCH is put on the multi-slot PUSCH for multiplexing transmission, all PUCCHs overlapped with the multi-slot PUSCH are discarded, the UCI carried by the slot n of the carrier 1 is transferred to the multi-slot PUSCH of the carrier 2 for transmission, and the PUCCH in the slot n and the slot n +1 of the carrier 1 is discarded;

when the third rule is used, as shown in fig. 7, if CSI is carried in the slot n on the carrier 1 and HARQ-ACK is carried in the slot n +1, it is first determined that the priority of UCI carried in the slot n +1 on the carrier 1 is higher, so that the HARQ-ACK carried in the slot n +1 on the carrier 1 is transferred to the multi-slot PUSCH on the carrier 2 for transmission, and the PUCCH in the slot n and the slot n +1 on the carrier 1 is discarded;

using the rule four, as shown in fig. 8, the UCI carried in slot n and slot n +1 on carrier 1 is transferred to the multi-slot PUSCH of carrier 2 together for transmission, and the PUCCH in slot n and slot n +1 on carrier 1 is discarded.

In summary, compared with the prior art, the present embodiment can effectively ensure the transmission performance of the UCI on the premise of ensuring that no uplink channel collision occurs.
