Reducing TTI as an important research direction for current delay reduction aims to reduce the current 1ms length of TTI to 0.5ms, or even 1 to 2 orthogonal frequency division multiplexing (OFDM) symbols, which is reduced exponentially. The minimum scheduling time, in turn, can double the single transmission delay without changing the frame structure. Currently, the Third Generation Partnership Project (3GPP) has also established a short TTI (sTTI) delay reduction technique.

The process of channel transmission is described in detail in Twelfth.

It should be noted that in the second to twelfth embodiments, the PUCCH of the sTTI can become The PUSCH of sPUCCH and sTTI may also be referred to as sPUSCH.

Embodiment 2

This embodiment provides a channel transmission method when the agreed transmission times of the PUSCH and the PUCCH overlap on one carrier, where the TTI lengths of the two channels are different. Here, the length of the TTI may be a 1 ms TTI in an existing Long Term Evolution (LTE) system, or the TTI includes 2 transmission symbols, 4 transmission symbols, or 7 transmission symbols, and the like. Wherein, 2 transmission symbols, 4 transmission symbols, or 7 transmission symbols may be physically continuous or discontinuous. For example, when the TTI length is 2 transmission symbols, the DMRS of the PUSCH is transmitted on the first transmission symbol on one subframe, and the uplink data is transmitted on the third transmission symbol of the subframe. The length of the TTI in practical applications is not limited to the TTI length described in this embodiment. In this embodiment, a TTI having a length of less than 1 ms is referred to as an sTTI. In this embodiment, the TTI length of the PUSCH is greater than the TTI length of the PUCCH. For example, the TTI length of the PUSCH is 1 ms, the TTI length of the PUCCH is 4 transmission symbols, or the TTI length of the PUSCH is 4 transmission symbols, and the TTI length of the PUCCH is 2 transmission symbols. In this embodiment, a scenario in which the transmission time of the PUSCH of the 1 ms TTI and the PUCCH of the sTTI overlap is taken as an example. The method in this embodiment can also be applied to other TTI length application scenarios. FIG. 2 is a schematic diagram showing when the transmission times of the PUSCH and the sPUCCH overlap. The UE detects the uplink grant in the subframe n, the UE will send the PUSCH in the subframe n+4, and in the subframe n+3, the UE receives the sPDSCH again, and needs to send the sPUCCH in the n+4 subframe.

For this situation, there are several ways to achieve this:

In the first mode, the sPUCCH and the PUSCH are simultaneously transmitted, that is, on the transmission symbol where the sPUCCH is located, the UE simultaneously transmits two channels.

The frequency domain resources corresponding to the sPUCCH and the PUSCH do not overlap. The method may also be used when the agreed transmission times of two or more channels overlap, and the two or more channels may be simultaneously transmitted.

In the second mode, if the sPUCCH includes the CSI, the CSI is sent on the PUSCH, for example, in the interleave matrix of the PUSCH, and the location of the write may be the transmission symbol location corresponding to the sPUCCH. If there is other information on the sPUCCH in addition to the CSI, the other information will be Transfer on sPUCCH. If there is no other information, the sPUCCH is not transmitted and only the PUSCH is transmitted.

Here, in actual application, if there is periodic CSI on the sPUCCH and aperiodic CSI on the PUSCH, the CSI on the sPUCCH abandons the transmission. If there is other information on the sPUCCH in addition to the CSI, the other information is transmitted on the sPUCCH. If there is no other information, the sPUCCH channel is not transmitted, and only the PUSCH is transmitted.

Embodiment 3

Similar to the first embodiment, the present embodiment provides a channel transmission method when the agreed transmission times of the PUSCH and the PUCCH overlap on one carrier, wherein the TTI lengths of the two channels are different.

In this embodiment, the TTI length of the PUSCH is greater than the TTI length of the PUCCH. In this embodiment, a scenario in which the transmission time of the PUSCH of the 1 ms TTI and the PUCCH of the sTTI overlap is taken as an example. The method in this embodiment may also be used for other TTI lengths.

For this situation, there are several ways to achieve this:

In the first mode, the UE transmits the sPUCCH and abandons the transmission of the PUSCH.

Optionally, when the PUSCH includes the UCI, all or part of the information of the UCI is transmitted on the sPUCCH. Here, the UCI includes at least one of the following: CQI and/or PMI (represented by CQI/PMI in the present invention), HARQ-ACK, RI, and CRI, where HARQ-ACK is feedback information of downlink data, such as 1 bit ACK/ NACK. The RI may be one of the following: only RI, joint reporting of RI and i1, joint reporting of CRI (CSI-RS resource indication, CSI-RS resource indication) and RI, joint reporting of CRI, RI and i1, CRI, Joint reporting of RI and PTI (Precoding Type Indicator), and joint reporting of RI and PTI. Where i1 is Wideband first PMI i1. The actual should not be limited to this information. Optionally, if the UCI includes a HARQ-ACK, the HARQ-ACK is transmitted on the sPUCCH, and if the UCI further contains other information, the other information is discarded.

Optionally, if the UCI includes a HARQ-ACK and/or an RI/CRI, the HARQ-ACK and/or the RI are transmitted on the sPUCCH, if the UCI further includes other information, Abandon the transmission of other information. For example, when UCI has HARQ-ACK and RI/CRI and CQI/PMI, HARQ-ACK and RI/CRI can be transmitted on sPUCCH, and CQI/PMI is discarded.

Optionally, if the UCI includes at least one of a HARQ-ACK, an RI/CRI, and a preset type CQI/PMI, at least one of the HARQ-ACK, the RI/CRI, and the preset type of CQI/PMI One of them is transmitted on the sPUCCH, giving up the transmission of other information.

The preset type CQI/PMI may be a CQI/PMI of some formats, such as a broadband CQI/PMI. For example, when UCI includes HARQ-ACK and RI/CRI and narrowband CQI/PMI, HARQ-ACK and RI/CRI can be transmitted on sPUCCH, and narrowband CQI/PMI abandons transmission.

When the transmission process is performed, if the sum of the number of bits of the UCI and the number of bits on the sPUCCH exceeds the number of bits that the sPUCCH can support, the HARQ-ACK bundling technique can be employed.

Information that is discarded in the UCI of the PUSCH may be transmitted on the next scheduled PUSCH.

In the second mode, the UE transmits the sPUCCH and delays transmission of the PUSCH.

For example, the PUSCH is deferred to the first subframe transmission without the PUSCH to be transmitted. For example, in FIG. 2, when the subframe n+5 has no PUSCH and the sPUCCH is to be transmitted, then the subframe n+5 is transmitted. The PUSCH that needs to be deferred, if the subframe n+5 has PUSCH and/or sPUCCH to be transmitted, it continues to be postponed until it is delayed until there is no subframe to be transmitted by the PUSCH. In practical applications, when there are overlapping transmission times of more than two uplink channels, and one of them is a PUCCH, and the TTI length of the PUCCH is the shortest, the above method can also be similarly used. In order to ensure the delay performance of the PUSCH with a short TTI length, the PUSCH with the shortest TTI length in the PUSCH and the PUCCH are processed as described above. Alternatively, the remaining PUSCHs may abandon the transmission or postpone the transmission. For example, in FIG. 3, an sPUCCH having 2 transmission symbols and an sPUSCH having 4 transmission symbols are processed in accordance with the method in this embodiment.

When there is one PUCCH and the transmission times of multiple PUSCHs overlap, the length of the TTI corresponding to the PUCCH is the smallest, as shown in FIG. 3, at this time, only the PUCCH is transmitted, and other channels are discarded. Optionally, the UCI on multiple PUSCHs is placed on the PUCCH for transmission, or only the UCI of the specified type is placed on the PUCCH for transmission. Similar to the previous description, such as specifying the type The UCI is HARQ-ACK, or at least one of HARQ-ACK and RI/CRI, or at least one of HARQ-ACK, RI/CRI, and preset type CQI/PMI. For example, only the HARQ-ARQ is placed on the sPUCCH for transmission. The actual application is not limited to this manner. For example, at least one of the HARQ-ARQ and the RI may be transmitted only on the sPUCCH.

When there are multiple PUCCHs, one or more PUSCHs have overlapping transmission times, the one with the smallest TTI length is one of the PUCCHs. Then, the PUCCH with the smallest TTI length is transmitted, and the UCI on the other PUCCH or the UCI of the specified type is transmitted on the PUCCH with the smallest TTI length. Abandon transmission of other channels or postpone transmission of other channels. Optionally, when there is UCI on the PUSCH, the UCI or the UCI of the specified type is transmitted on the PUCCH with the smallest TTI length. Here, the UCI on the PUCCH includes at least one of CSI, SR, and HARQ-ACK. The UCI of the specified type may be at least one of HARQ-ACK, or SR, or SR and HARQ-ACK, or preset types of CSI, SR, and HARQ-ACK. Here, the preset type of CSI may be a wideband CSI or the like, and this definition is also used in the following embodiments. For example, a 2-symbol PUCCH, a 4-symbol PUSCH, a 7-symbol PUCCH, and a 1 ms PUSCH, then only a 2-symbol PUCCH is transmitted. The UCI on the other PUCCH and PUSCH can be transmitted on the 2-symbol PUCCH.

When there are multiple PUCCHs, one or more PUSCHs have overlapping transmission times, where the minimum TTI length is PUSCH, then only one PUCCH with the smallest TTI length among the multiple PUCCHs, UCI on other PUCCHs or The UCI of the specified type is transmitted on the PUCCH with the smallest TTI length. Abandon the transmission of the remaining channels or postpone the transmission of the remaining channels. Optionally, when there is UCI on the PUSCH, the UCI or the UCI of the specified type is transmitted on the PUCCH with the smallest TTI length. For example, a 2-signal PUSCH, a 4-symbol PUCCH, a 7-symbol PUCCH, and a 1 ms PUSCH, then only a 4-symbol PUCCH is transmitted. The UCI on the other PUCCH and PUSCH can be transmitted on the 2-symbol PUCCH.

Embodiment 4

Similar to the first embodiment, in this embodiment, on one carrier, when the agreed transmission times of the PUSCH and the PUCCH overlap, the channel transmission method is different, and the TTI lengths of the two channels are different.

In this case, in the present embodiment, only the PUSCH is transmitted. Specifically, prior to the discrete Fourier transform (DFT) operation, the UCI on the sPUCCH is punctured on the interleaving matrix of the PUSCH. Here, the UCI on the sPUCCH may also be referred to as partial information on the PUSCH in the interlace matrix.

An example is given below. The transmission time corresponding to the PUSCH is the subframe n, and the transmission time corresponding to the sPUCCH is the first two transmission symbols on the subframe n. Then, in the interlace matrix of the PUSCH, the column corresponding to the first two transmission symbols is covered by the UCI on the sPUCCH. .

Optionally, the UCI on the sPUCCH may occupy data on an interlace matrix corresponding to the transmission symbol corresponding to the sPUCCH. For example, the interleaving matrix of the PUSCH is a matrix of (R _mux × C _mux ), R _mux is the number of rows, and C _mux is the number of columns, as shown in FIG. 4 . In FIG. 4, each element y _i (i is an integer, and 0 ≤ _i ≤ (R' _mux × C _mux -1)) in the interleaving matrix is a vector of one column (Q _m · N _L ). R' _mux = R _mux / (Q _m · N _L ), where Q _m is the modulation order and N _L is the number of layers.

The number of symbols transmitted for the PUSCH does not include the symbol for transmitting the DMRS, and if there is an SRS, the symbol for transmitting the SRS is not included.

Since the sPUCCH occupies the first two transmission symbols in the interlace matrix, the sPUCCH will cover the information of the PUSCH on the column corresponding to the first two symbols in the interlace matrix, that is, cover the first two columns. As shown in Figure 5.

Optionally, when the transmission symbol corresponding to the sPUCCH includes the transmission symbol where the DMRS of the PUSCH is located, the DMRS of the PUSCH is still transmitted on the transmission symbol where the DMRS of the PUSCH is located.

More specifically, when the transmission symbol corresponding to the sPUCCH and the transmission symbol corresponding to the DMRS of the PUSCH do not overlap, only the DMRS corresponding to the PUSCH is transmitted on the subframe; the transmission symbol corresponding to the sPUCCH and the transmission symbol corresponding to the DMRS of the PUSCH When there is overlap, the DMRS of the PUSCH is still transmitted on the transmission symbol corresponding to the DMRS of the PUSCH. The sPUCCH is transmitted only on symbols corresponding to other sPUCCHs other than the transmission symbol of the DMRS.

Optionally, the number of resources occupied by the UCI on the sPUCCH is configured by the eNB, such as calculation. The parameters in the formula of the number of resources occupied by the sPUCCH are configured by the eNB.

Optionally, when the UCI on the sPUCCH is written into the interlace matrix of the PUSCH, the UCI is written in a preset manner, such as writing from top to bottom, or from line to line, from bottom to top.

Alternatively, the UCI on the sPUCCH may be transmitted on all transport blocks of the PUSCH, or may also be transmitted on one of the 2 transport blocks of the PUSCH. In an embodiment, the UCI on the sPUCCH is sent on a transport block with a larger MCS index value. When the MCS index values of the two transport blocks are the same, the UCS may be sent on a preset transport block, for example, in the first transmission. Send on the block, etc.

Alternatively, when transmitting in one transport block of the PUSCH, it may be sent on all layers corresponding to the transport block or on a partial layer. For example, the transmission is repeated on all layers on the transport block of the PUSCH.

Optionally, when the UCI is included in the PUSCH, the information corresponding to the UCI on the PUSCH should be skipped when the UCI information in the sPUCCH is written.

Optionally, when there is at least one of RI/CRI and CQI/PMI on the PUSCH, the UCI of the sPUCCH cannot cover part or all of the information of at least one of the RI/CRI and the CQI/PMI, ie, in the RI/ The information of the PUSCH is covered in addition to part or all of the information of at least one of the CRI and the CQI/PMI, that is, rate matching is performed in addition to part or all of the information of at least one of the RI/CRI and the CQI/PMI.

Optionally, when there is a HARQ-ACK on the PUSCH, the HARQ-ACK performs puncturing after the information of the sPUCCH is written into the interlace matrix.

Optionally, the UCI on the sPUCCH may adopt independent modulation coding, or may adopt the same modulation and coding manner as the PUSCH.

In practical applications, when there are overlapping transmission times of PUSCHs with more than two TTI lengths, the above method can also be similarly used. In order to ensure the delay performance of the PUCCH of a shorter TTI length, the PUSCH and PUCCH with the shortest TTI length are processed as described above. For example, in FIG. 3, an sPUCCH having 2 transmission symbols and an sPUSCH having 4 transmission symbols are processed in accordance with the method in this embodiment. The 1ms PUSCH abandons the transmission.

When there are multiple PUCCHs, one or more PUSCHs have overlapping transmission times, Only the PUSCH with the shortest TTI length among the multiple PUSCHs is transmitted, and the remaining channels abandon the transmission or delay the transmission. Optionally, when the TTI length of only one PUCCH is smaller than the TTI length of the PUSCH with the shortest TTI length in the multiple PUSCHs, the UCI on the PUCCH or the TTI of the specified type in the multiple PUSCHs The transmission is performed on the PUSCH having the shortest length, and the transmission method is the same as that in the above embodiment. Optionally, when there are multiple PUCCHs whose TTI length is smaller than a TTI length of a PUSCH with the shortest TTI length in the multiple PUSCHs, the UCI on the multiple PUCCHs or the UCI of the specified type is in the multiple PUSCHs. The TTI is transmitted on the shortest PUSCH. The transmission location may be a symbol corresponding to the PUCCH having the shortest TTI length among the plurality of PUCCHs. As shown in Figure 6. The four-channel agreed transmission time overlaps. The PUSCH of the shortest TTI length in the PUSCH is a 7-symbol sPUSCH, and the 7-symbol sPUSCH is transmitted, and the other channels abandon the transmission. There are two PUCCHs shorter than the 7-symbol TTI length, that is, 4-symbol sPUCCH and 2-symbol sPUCCH, UCI on these two channels writes 7-symbol sPUSCH, and the written position is 4-symbol The symbol corresponding to the PUCCH of the shortest TTI length in the sPUCCH and the 2-symbol sPUCCH, that is,

symbols #

12 and 13, that is, the mesh portion.

Embodiment 5

Similar to the first embodiment, in this embodiment, on one carrier, when the agreed transmission times of the PUSCH and the PUCCH overlap, the channel transmission methods are different, and the lengths of the two channels corresponding to the TTI are different.

In this embodiment, only the sPUCCH is transmitted on the symbol corresponding to the sPUCCH, and the PUSCH is not transmitted, and the PUSCH is still transmitted on the remaining symbols corresponding to the PUSCH. As shown in FIG. 7, FIG. 7 is 14 transmission symbols in one subframe, in which sPUCCH occupies

symbols #

6 and 7, and slash portions are DMRSs. In this method, the frequency domain resources corresponding to the sPUCCH and the PUSCH may be overlapping, or not overlapping or partially overlapping.

That is, the PUSCH, sPUCCH is not transmitted on the transmission symbol where the sPUCCH is located. The information of the remaining PUSCHs other than the transmitted symbols is still transmitted.

When UCI is included on the PUSCH, the UCI is placed on the sPUCCH for transmission. Or, when the UCI is included in the PUSCH, and the symbol in which the UCI is located overlaps with the symbol corresponding to the sPUCCH, the UCI is placed on the sPUCCH for transmission.

Optionally, if the UCI includes a HARQ-ACK, the HARQ-ACK is transmitted on the sPUCCH, and if the UCI further contains other information, the other information is discarded.

Optionally, if the UCI includes HARQ-ACK and/or RI/CRI, the HARQ-ACK and/or RI are transmitted on the sPUCCH, and if the UCI further contains other information, the other information is discarded. . For example, when UCI has HARQ-ACK and RI/CRI and CQI/PMI, HARQ-ACK and RI/CRI can be transmitted on sPUCCH, and CQI/PMI is discarded.

In order to avoid affecting the DMRS and/or UCI corresponding to the PUSCH, further, when the sPUCCH corresponding transmission symbol corresponds to the DMRS and/or UCI on the PUSCH, the sPUCCH may be deferred.

Optionally, when the overlapping part of the sPUCCH and the PUSCH includes the symbol in which the DMRS is located, one DMRS may be generated according to the sPUCCH and the PUSCH frequency domain span, that is, one DMRS is generated from the lowest frequency to the highest frequency of the two.

In actual application, when there is UCI on the PUSCH, it can be sent by one of the following methods:

The first mode: the positional relationship of the transmission symbol corresponding to the sPUCCH corresponding to the UCI of the PUSCH is not considered at all, and the UCI is transmitted on the sPUCCH as long as there is UCI on the PUSCH.

Optionally, if the UCI includes a HARQ-ACK and/or an RI/CRI, the HARQ-ACK and/or the RI are transmitted on the sPUCCH, if the UCI further includes other information, Abandon the transmission of other information.

Optionally, if the UCI includes at least one of a HARQ-ACK, an RI/CRI, and a preset type CQI/PMI, at least one of the HARQ-ACK, the RI/CRI, and the preset type CQI/PMI One is placed on the sPUCCH for transmission, and the other information is discarded.

The second mode is: when there is UCI on the PUSCH, and the transmission symbol corresponding to the sPUCCH and the symbol corresponding to the UCI overlap, the UCI of the overlapping part is placed on the sPUCCH for transmission; when the UCI does not overlap, the UCI is still placed on the PUSCH. on.

Here, the overlap of symbols means that some of the symbols are the same. For example, if the transmission symbol corresponding to the sPUCCH overlaps with the transmission symbol in which the HARQ-ACK and/or the CSI are located, the HARQ-ACK and/or the CSI are placed on the sPUCCH. As shown in FIG. 8, when the sPUCCH corresponds to the first two transmission symbols, if there is only RI transmission on the PUSCH, the RI is placed on the PUSCH for transmission.

Optionally, if the UCI includes HARQ-ACK and/or RI/CRI, the HARQ-ACK and/or RI are transmitted on the sPUCCH, and if the UCI further contains other information, the other information is discarded.

In a third mode, when the transmission symbol corresponding to the sPUCCH and the transmission symbol corresponding to all or part of the information of the UCI overlap, the sPUCCH is still transmitted on the overlapping transmission symbol.

The fourth mode: when the transmission symbol corresponding to the sPUCCH and the transmission symbol corresponding to all or part of the information of the UCI overlap, the sPUCCH is postponed to a position that does not conflict with the UCI. For example, postpone the next sTTI without UCI information.

In actual application, when the symbol corresponding to the sPUCCH and the symbol of the DMRS of the PUSCH overlap, the following manner may be used:

The first way: sPUCCH is transmitted on the transmission symbol where the DMRS is located, and the remaining can be used. The DMRS on the other symbols below demodulates the PUSCH. For example, the sPUCCH is demodulated on the first time slot by using the DMRS on the second time slot.

The second way: generate a DMRS according to the sPUCCH and PUSCH frequency domain span. As shown in Figure 9. The transmission symbols corresponding to the sPUCCH are

symbols #

2 and 3, and overlap with the DMRS symbols of the first slot. In this case, a DMRS is generated according to the frequency domain span of the PUSCH and the sPUCCH, that is, the lowest frequency to the highest frequency are generated. A DMRS. The time domain location of the DMRS may be the transmission symbol of the DMRS of the PUSCH, or may be the transmission symbol of the sPUCCH, and the time domain location of the DMRS in FIG. 9 is the symbol of the DMRS.

When the transmission times of channels having more than two TTI lengths overlap, the above method can also be similarly employed. In order to ensure the delay performance of the channel with a short TTI length, the PUSCH and PUCCH with the shortest TTI length are processed as described above. For example, the sPUSCH having 2 transmission symbols and the sPUCCH having 4 transmission symbols in FIG. 3 are processed in accordance with the method in this embodiment.

Or, when there are overlapping transmission times of channels having more than 2 TTI lengths, only one designated channel is transmitted on one transmission symbol, where

The designated channel satisfies one of the following conditions:

Among the two or more channels, only the agreed transmission time of the designated PUSCH includes the transmission symbol;

In the two or more channels, the agreed transmission time of the plurality of channels includes the transmission symbol, and among the plurality of channels, the TTI length corresponding to the designated channel is the smallest.

Figure 10 shows a schematic diagram. The agreed transmission times of PUSCHs with three TTI lengths overlap, which are 1 ms PUSCH, 4 symbols sPUCCH and 2 symbols sPUCCH, where the 1 ms PUSCH agreed transmission time is symbol #0~ The agreed transmission time of the sPUCCH of 13,4 symbols is the symbols #5 to 8, and the agreed transmission time of the sPUCCH of the 2 symbols is

symbols #

7 and 8. Then, only two symbols of sPUCCH are transmitted on

symbols #

7 and 8, and only four symbols of sPUCCH are transmitted on

symbols #

5 and 6, and only symbols are transmitted on the remaining symbols, symbols #0 to 4 and 9 to 13, 1ms PUSCH.

The processing of the UCI is similar to the above, for example, all UCIs on the PUSCH and sPUCCH or UCI of the specified type are transmitted on the sPUCCH. Or only the UCI that was knocked out or destroyed The specified type of UCI is transmitted on the sPUCCH.

Embodiment 6

This embodiment provides a channel transmission method when the agreed transmission times of the PUSCH and the PUCCH overlap on one carrier, where the TTI lengths of the two channels are different. Here, the length of the TTI may be a 1 ms TTI in the existing LTE system, or the TTI includes 2 transmission symbols, 4 transmission symbols, or 7 transmission symbols, and the like. Wherein, 2 transmission symbols, 4 transmission symbols, or 7 transmission symbols may be physically continuous or discontinuous. For example, when the TTI length is 2 transmission symbols, the DMRS of the PUSCH is transmitted on the first transmission symbol on one subframe, and the uplink data is transmitted on the third transmission symbol of the subframe. The length of the TTI in practical applications is not limited to the TTI length described in this embodiment. In this embodiment, a TTI having a length of less than 1 ms is also referred to as an sTTI.

In this embodiment, the TTI length of the PUSCH is smaller than the TTI length of the PUCCH. For example, the TTI length of the PUCCH is 1 ms, the TTI length of the PUSCH is 4 transmission symbols, or the TTI length of the PUCCH is 4 transmission symbols, and the TTI length of the PUSCH is 2 transmission symbols. In this embodiment, a scenario in which the transmission time of the PUCCH of the 1 ms TTI and the sPUSCH of the sTTI overlap is taken as an example. The method in this embodiment can also be applied to other TTI length application scenarios.

The UCI on the PUCCH includes at least one of CSI, SR, and HARQ-ACK. Send sPUSCH and abandon transmission PUCCH. Optionally, the UCI on the PUCCH is placed on the sPUSCH for transmission, or the designated UCI on the PUCCH is placed on the sPUSCH for transmission. details as follows.

Optionally, if the UCI includes an SR, the SR is transmitted on the sPUCCH, and if the UCI further contains other information, the other information is discarded.

Optionally, if the UCI includes a HARQ-ACK and/or an SR, the HARQ-ACK and/or the SR are transmitted on the sPUCCH, and if the UCI further contains other information, the other information is discarded.

Optionally, if the UCI includes at least one of a HARQ-ACK, an SR, and a preset type of CSI, at least one of the HARQ-ACK, the SR, and the preset type of CSI is transmitted on the sPUCCH. , give up transmitting other information. Here, the preset type of CSI may be a wideband CSI, and the actual application is not limited to the CSI of the form.

For example, the information on the PUCCH is: HARQ-ACK and periodic CSI feedback, then the HARQ-ACK is transmitted on the sPUSCH, and the periodic CSI feedback is not transmitted on the sPUSCH.

The PUCCH discards the transmission except for the information transmitted on the sPUSCH.

Optionally, the information on the PUCCH that abandons transmission is deferred to transmission on subsequent subframes.

The method in this embodiment can also be used when the agreed transmission times of two or more channels overlap. When the shortest TTI length among the plurality of uplink channels is the PUSCH, the UCI on the other PUCCH channel or the UCI of the specified type is transmitted on the PUSCH, similar to the above. Optionally, on other PUSCH channels, if there is also UCI information, these UCIs may also be transmitted on the sPUSCH. Here, when the sPUSCH also includes the UCI, the UCI described above may be transmitted in a cascade manner with the UCI on the sPUSCH.

Example 7

Similar to the sixth embodiment, the present embodiment provides a channel transmission method when the agreed transmission times of the PUSCH and the PUCCH overlap on one carrier, where the TTI lengths of the two channels are different.

In this embodiment, the TTI length of the PUSCH is smaller than the TTI length of the PUCCH. In this embodiment, the scenario in which the transmission time of the PUCCH of the 1 ms TTI and the sPUSCH of the sTTI overlap is used as an example. The method in this embodiment may also be applied to other TTI-length application scenarios.

In this embodiment, the PUCCH and the sPUSCH are simultaneously transmitted, that is, on the transmission symbol where the sPUSCH is located, the UE simultaneously transmits two channels.

The frequency domain resources corresponding to the PUCCH and the sPUSCH do not overlap.

The method may also be used when there is overlap between one or more PUCCHs and one or more PUSCHs, and when their corresponding frequency domain resources do not overlap, all channels are simultaneously transmitted.

Example eight

This embodiment provides a transmission method when the agreed transmission times of the plurality of PUCCHs overlap on one carrier, wherein the TTIs of the plurality of PUCCHs have different lengths.

In this embodiment, a scenario in which the transmission time of the PUCCH of the 1 ms TTI and the sPUCCH of the sTTI overlap is taken as an example. The method in this embodiment can also be used for other TTI lengths.

In this embodiment, the UE simultaneously transmits the PUCCH and the sPUCCH, that is, on the symbol where the sPUCCH is located, the UE simultaneously sends two channels.

The frequency domain resources corresponding to the PUCCH and the sPUCCH do not overlap.

Example nine

This embodiment provides a channel transmission method when the agreed transmission times of a plurality of PUCCHs overlap on one carrier. The plurality of PUCCHs have different TTI lengths.

In this embodiment, the scenario in which the transmission time of the PUCCH of the 1 ms TTI and the sPUCCH of the sTTI overlap is taken as an example. The method in this embodiment may also be used for other TTI lengths.

Here are a few ways to send, which can be sent using one of the following methods:

The first way is to send the sPUCCH, abandon the transmission of the PUCCH, or defer the PUCCH to the subsequent subframe for transmission.

The second mode is: sending sPUCCH, and placing UCI on the PUCCH or UCI of the specified type on the sPUCCH for transmission.

Optionally, if the UCI includes a HARQ-ACK, the HARQ-ACK is transmitted on the sPUCCH, and if the UCI further contains other information, the other information is discarded. If the HARQ-ACK is not included in the UCI, the information contained in the sPUCCH is transmitted only on the sPUCCH.

Optionally, if the UCI includes an SR, the SR is transmitted on the sPUCCH, and if the UCI further contains other information, the other information is discarded. If the UCI does not include an SR, the information contained in the sPUCCH is transmitted only on the sPUCCH.

Optionally, if the UCI includes a HARQ-ACK and/or an SR, the HARQ-ACK is And/or the RI is transmitted on the sPUCCH, and if the UCI also contains other information, the transmission of other information is abandoned. For example, when UCI has HARQ-ACK and SR and CQI/PMI, HARQ-ACK and SR can be transmitted on sPUCCH, and CQI/PMI abandons transmission.

Optionally, if the UCI includes at least one of a HARQ-ACK, an SR, and a preset type CSI, at least one of the HARQ-ACK, the SR, and the preset type of CSI is transmitted on the sPUCCH, Abandon the transmission of other information. Here, the preset type of CSI may be CSI in some formats, such as a wideband CSI. For example, when UCI has HARQ-ACK and SR and narrowband CSI, HARQ-ACK and SR can be transmitted on narrowband sPUCCH, and narrowband CSI abandons transmission.

Optionally, if the sum of the number of bits of the UCI and the number of bits on the sPUCCH exceeds the number of bits that the sPUCCH can support, the HARQ-ACK bundling technique may be adopted.

The third way: on the transmission symbol where the sPUCCH is located, the PUCCH is not transmitted. On the remaining symbols, the PUCCH is still transmitted.

The fourth mode: determining to transmit one of the channels according to the time domain location of the sPUCCH. For example, when the last transmission symbol of the sPUCCH exceeds the mth symbol in the subframe, the PUCCH is transmitted, and if the last transmission symbol of the sPUCCH does not exceed the mth transmission symbol, the sPUCCH is sent, for example, , m=7. That is to say, when the sPUCCH is located in the first time slot, the sPUCCH is transmitted, and when the sPUCCH is located in the second time slot, the PUCCH is transmitted.

Optionally, which manner is used may be determined according to the TTI length corresponding to the sPUSCH.

Optionally, the eNB may configure whether the sPUCCH and the PUCCH can be simultaneously transmitted to the UE. If it can be transmitted at the same time, it is transmitted by the method in Embodiment 8, otherwise it is transmitted in one of the modes in this embodiment.

Example ten

If the TTI length of one PUCCH and the TTI length of one of the PUSCHs are the same, all or part of the information of the UCI on the PUCCH is transmitted on the PUSCH having the same TTI length as the PUCCH. Preferably, if there are multiple PUSCHs having the same TTI length as the PUCCH, the PUSCH is selected for transmission according to a preset rule, for example, if one of the multiple PUSCHs is on the primary carrier, then on the primary carrier. Transmitted on the PUSCH, or if the multiple PUSCHs are all on the secondary carrier, the PUSCH on the carrier with the smallest or largest ScellIndex is transmitted.

For the remaining PUCCH, that is, the PUSCH having the same length as its TTI, the remaining PUCCH is transmitted on the designated PUSCH, for example, if there is a PUSCH on the primary carrier, it is sent on the PUSCH on the primary carrier, or if There is no PUSCH on the primary carrier, and the PUSCH on the carrier with the smallest or largest ScellIndex is transmitted. Alternatively, the PUSCH with the smallest TTI length is selected for transmission.

The carrier with a STIIndex of 0 has a TTI length of 4 and a scellIndex of 1 on the carrier. The length of the TSCH of the PUSCH is 2, and there are three PUCCHs, and the lengths of the TTIs are 2, 4, and 7, respectively. Then, the information on the PUCCH with the TTI length of 2 is transmitted on the carrier with the scellIndex of 1, and the PUCCH with the length of the TTI is 2. The information is sent on a carrier with scellIndex 0. A PUCCH with a TTI length of 7 may be transmitted on the shortest PUSCH of the TTI, that is, on a carrier with a scellIndex of 1. The manner of transmission can be referred to the aforementioned embodiment.

Optionally, in the multiple PUCCHs, the UCI or UCI designation information on the PUCCH except the PUCCH with the shortest TTI length is transmitted on the transmitted PUCCH channel, for example, only the HARQ-ACK is in the Transmitted on the PUCCH.

Example twelve

In this embodiment, all PUSCHs are transmitted. If the TTI length of one PUCCH is the same as the TTI length of one of the PUSCHs, all or part of the information of the UCI on the PUCCH is transmitted on the PUSCH having the same TTI length as the PUCCH. Preferably, if there are multiple PUSCHs having the same TTI length as the PUCCH, the PUSCH is selected for transmission according to a preset rule, for example, if one of the multiple PUSCHs is on the primary carrier, then on the primary carrier. Transmitted on the PUSCH, or if the multiple PUSCHs are all on the secondary carrier, the PUSCH on the carrier with the smallest or largest ScellIndex is transmitted.

For the remaining PUCCHs, that is, the PUSCHs having the same TTI length, the PUCCH with the smallest TTI in the remaining PUCCHs is selected for transmission, and all or part of the information on the other PUCCHs is also transmitted in the PUCCH with the smallest TTI. That is to say, all PUSCHs and one PUCCH are transmitted.

An example is given below. There are two carriers, ScellIndex is 0 and 1, respectively, and each carrier has a PUSCH. The carrier with a STIIndex of 0 has a TTI length of 4 and a scellIndex of 1 on the carrier. The length of the TSCH of the PUSCH is 2, and there are three PUCCHs, and the lengths of the TTIs are 2, 4, and 7, respectively. Then, the information on the PUCCH with the TTI length of 2 is transmitted on the carrier with the scellIndex of 1, and the PUCCH with the length of the TTI is 2. The information is sent on a carrier with scellIndex 0. A PUCCH with a TTI length of 7 is transmitted separately. That is to say, a PUCCH with a TTI length of 7 and two PUSCHs with TTI lengths of 2 and 4 are transmitted.

Example thirteen

This embodiment provides a channel transmission method when the agreed transmission times of a plurality of PUCCHs overlap on one carrier. The plurality of PUCCHs have different TTI lengths. The priority is determined according to the TTI length of the UCI and/or PUCCH carried by the PUCCH, the PUCCH with the highest priority is selected for transmission, the remaining PUCCH is discarded, or the remaining PUCCH is deferred until the agreed transmission time.

Prioritize based on at least one of the following:

1) The priority of the PUCCH carrying the HARQ-ACK is higher than the priority of the PUCCH carrying the CSI, that is, when two PUCCHs, one carrying the HARQ-ACK and the other carrying the CSI, transmitting the PUCCH carrying the HARQ-ACK, abandoning the transmission The PUCCH carrying the CSI.

2) The priority of the PUCCH carrying the SR is higher than the priority of the PUCCH carrying the CSI.

3) When the UCI types are the same, the PUCCH with a short TTI length has a higher priority than the corresponding PUCCH with a long TTI length. For example, a PUCCH with a TTI length of 1 ms and a PUCCH with a length of 0.5 ms carry HARQ- ACK, then the PUCCH with a length of 0.5 ms has a high priority.

4) A PUCCH having a short TTI length carrying a HARQ-ACK and/or an SR has a higher priority than a PUCCH having a long TTI length carrying a HARQ-ACK and/or an SR.

Optionally, the UCI on the remaining channels is transmitted on the highest priority control channel.
