Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

The TTI is reduced as an important research direction of current delay reduction, and the current TTI with the length of 1ms is reduced to the length of 0.5ms or even 1-2 Orthogonal Frequency Division Multiplexing (OFDM) symbols, so that the minimum scheduling time is reduced exponentially, and further, the single transmission delay can be reduced exponentially under the condition of not changing a frame structure. Currently, the third generation partnership project (3GPP) has also established a discussion of short tti (stti) latency reduction techniques.

When the delay is reduced by reducing the TTI, the TTI lengths corresponding to the channels may be different when different channels are transmitted, and the channels with different TTI lengths overlap with each other in transmission time, and how to perform channel transmission in this case does not currently have a solution. In particular, in short TTI technologies, the User Equipment (UE) needs to support sTTI and the existing 1ms length TTI, between which the UE can dynamically switch. When the channel of the short TTI and the channel of the 1ms TTI overlap in transmission time, there is no effective solution for how to perform channel transmission, which is a problem to be solved urgently at present.

Based on this, in various embodiments of the invention: when the appointed transmission time of at least two uplink channels is overlapped, the sending equipment determines a sending mode and sends a target signal according to the sending mode; the sending mode is preset and/or indicated by the base station; at least two uplink channels in the at least two uplink channels have different corresponding TTI lengths; the uplink channel is a data channel or a control channel, and at least one control channel is arranged in the at least two uplink channels.

Here, the method may further include:

Wherein, the method can also comprise:

It should be noted that: in practical application, when the channel where the UCI is located is a data channel, the UCI may include at least one of the following information: HARQ-ACK, RI/CRI, CQI/PMI.

When the channel where the UCI is located is a data channel, the specified information is one of the following information:

HARQ-ACK；

at least one of HARQ-ACK and RI/CRI;

at least one of HARQ-ACK, RI/CRI and CQI/PMI of a preset type.

When the channel where the UCI is located is a control channel, the specified information is one of the following information:

HARQ-ACK；

SR；

at least one of HARQ-ACK and SR;

at least one of a preset type of CSI, HARQ-ACK, and SR.

It should be noted that: in practical applications, a receiving device (e.g., a base station) may also know the transmission mode of the transmitting device, and receive a corresponding target signal in the same manner as the transmission mode of the transmitting device.

According to the information sending method provided by the embodiment of the invention, when the appointed transmission time of at least two uplink channels is overlapped, a sending mode is determined, and a target signal is sent according to the sending mode; the sending mode is preset and/or indicated by the base station; at least two uplink channels in the at least two uplink channels have different corresponding transmission time interval TTI lengths; the uplink channel is a data channel or a control channel, and at least one control channel is arranged in the at least two uplink channels, so that when the channels with different TTI lengths are overlapped in the transmission time, the transmission of each channel can be effectively realized.

In the following, taking the control CHannel as a Physical Uplink Control CHannel (PUCCH), and the data CHannel as a Physical Uplink Shared CHannel (PUSCH) as an example, on the basis of the first embodiment, the CHannel transmission process is described in detail in embodiments two to twelve.

It should be noted that: in embodiments two to twelve, the PUCCH of sTTI may be called sPUCCH, and the PUSCH of sTTI may be called sPUSCH.

Example two

The embodiment provides a channel transmission method when the appointed transmission time of the PUSCH and the PUCCH is overlapped on one carrier, wherein the TTI lengths corresponding to the two channels are different. Here, the length of the TTI may be a 1ms TTI in an existing Long Term Evolution (LTE) system, or the TTI may contain 2 transmission symbols, 4 transmission symbols, or 7 transmission symbols, etc. 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 for the PUSCH is transmitted on the first transmission symbol in a subframe, and the uplink data is transmitted on the third transmission symbol in the subframe. The length of TTI in practical application is not limited to the TTI length described in this embodiment. In this embodiment, a TTI of length less than 1ms is referred to as sTTI. In this embodiment, the TTI length of the PUSCH is larger than the TTI length of the PUCCH. For example, the TTI length of the PUSCH is 1ms, and 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. This embodiment will be described by taking as an example a scenario in which the transmission times of the PUSCH of the 1ms TTI and the PUCCH of the sTTI overlap. The method in this embodiment may also be used in application scenarios with other TTI lengths. Fig. 2 shows a schematic diagram when there is an overlap between the transmission times of PUSCH and sPUCCH. The UE detects the uplink grant in subframe n, and the UE is to send the PUSCH in subframe n +4, and in subframe n +3, the UE receives the sPDSCH again, and needs to send the sPUCCH in subframe n + 4.

For this case, there can be several implementations as follows:

in the first mode, sPUCCH and PUSCH are transmitted simultaneously, that is, on the transmission symbol where sPUCCH is located, the UE transmits 2 channels simultaneously.

Wherein, the frequency domain resources corresponding to the sPUCCH and the PUSCH are not overlapped. This approach may also be used when there is an overlap in the agreed transmission times for more than two channels, and the more than two channels may be transmitted simultaneously.

In a second way, if the sPUCCH contains CSI, the CSI is sent on the PUSCH, for example, written in an interleaving matrix of the PUSCH, where the written position may be a transmission symbol position corresponding to the sPUCCH. If other information besides the CSI exists on the sPUCCH, the other information is placed on the sUCCH for transmission. And if no other information exists, the sPUCCH is not sent, and only the PUSCH is sent.

Here, in actual application, if there is periodic CSI on the sPUCCH and there is aperiodic CSI on the PUSCH, the CSI on the sPUCCH abandons transmission. If the sPUCCH has other information besides the CSI, the other information is put on the sUCCH for transmission. And if no other information exists, the sPUCCH channel is not sent, and only the PUSCH is sent.

EXAMPLE III

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

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

For this case, there can be several implementations as follows:

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

Optionally, when the PUSCH contains UCI, all or part of the UCI is transmitted on sPUCCH. Here, the UCI includes at least one of: CQI and/or PMI (expressed by CQI/PMI in the invention), HARQ-ACK, RI and CRI, wherein the HARQ-ACK is feedback information of downlink data, such as ACK/NACK with 1 bit. The RI may be one of: only joint reporting of RI, and i1, joint reporting of CRI (CSI-RS resource indication) and RI, joint reporting of CRI, RI, and i1, joint reporting of CRI, RI, and PTI (Precoding Type Indicator), and joint reporting of RI and PTI. Wherein i1 is Wideband first PMI i 1. And in practice should not be limited to such information. Optionally, if the UCI includes HARQ-ACK, the HARQ-ACK is put on sPUCCH for transmission, and if the UCI also includes other information, transmission of the other information is abandoned.

Optionally, if the UCI includes HARQ-ACK and/or RI/CRI, the HARQ-ACK and/or RI is placed on sPUCCH for transmission, and if the UCI also includes other information, transmission of the other information is abandoned. For example, when the UCI has HARQ-ACK and RI/CRI and CQI/PMI, the HARQ-ACK and RI/CRI may be put on the sPUCCH for transmission, and the CQI/PMI may give up transmission.

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

The preset type CQI/PMI may be a CQI/PMI of some format, such as a wideband CQI/PMI and the like. For example, when the UCI includes HARQ-ACK and RI/CRI and narrowband CQI/PMI, the HARQ-ACK and RI/CRI may be put on the sPUCCH for transmission, and the narrowband CQI/PMI abandons the transmission.

During transmission processing, 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, a HARQ-ACK bundling technique may be used.

The information that is abandoned from transmission in the UCI of the PUSCH may be transmitted on the next scheduled PUSCH.

In the second way, the UE transmits sPUCCH and defers PUSCH transmission.

For example, the PUSCH is deferred until the first subframe transmission without PUSCH is transmitted, such as in fig. 2, when subframe n +5 has no PUSCH and sPUCCH to transmit, the PUSCH that needs to be deferred is transmitted at subframe n +5, and if subframe n +5 has PUSCH and/or sPUCCH to transmit, the PUSCH continues to be deferred until the subframe where no PUSCH is to transmit is deferred. In practical application, when there is an overlap between the transmission times of more than two uplink channels, and one of the uplink channels is a PUCCH, and the TTI length of the PUCCH is the shortest, the above method may be similarly employed. In order to guarantee the time delay performance of the PUSCH with the shorter TTI length, the PUSCH with the shortest TTI length in the PUSCH and the PUCCH are processed according to the mode. Optionally, the remaining PUSCHs may give up transmission or defer transmission. For example, in fig. 3, sPUCCH with 2 transmission symbols and sPUSCH with 4 transmission symbols are processed according to the method in this embodiment.

When there is an overlap between transmission times of one PUCCH and a plurality of PUSCHs, where the TTI length corresponding to the PUCCH is the minimum, as shown in fig. 3, only the PUCCH is transmitted, and transmission of other channels is abandoned. Optionally, the UCI on a plurality of PUSCHs is put on the PUCCH for transmission, or only the UCI of a specified type is put on the PUCCH for transmission. Similar to the foregoing description, for example, the UCI of the designated type 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 HARQ-ARQ is put on the sUCCH for transmission. The practical application is not limited to this way, for example, only at least one of HARQ-ARQ and RI may be put on sPUCCH for transmission.

When there is an overlap of transmission times of multiple PUCCHs and one or multiple PUSCHs, the smallest TTI length is one of the PUCCHs. The PUCCH with the smallest TTI length is transmitted, and UCI on other PUCCHs or UCI of a specified type is transmitted on the PUCCH with the smallest TTI length. Relinquishing or deferring transmission of other channels. Optionally, when there is UCI on PUSCH, transmitting the UCI or a specified type of UCI on PUCCH with the smallest TTI length. Here, UCI on PUCCH includes at least one of CSI, SR, and HARQ-ACK. The specified type of UCI may be at least one of HARQ-ACK, or SR and HARQ-ACK, or a preset type of CSI, SR, and HARQ-ACK. Here, the preset type of CSI may be wideband CSI or others, and this definition is also used in the following embodiments. For example, there are 2-symbol PUCCH, 4-symbol PUSCH, 7-symbol PUCCH, and 1ms PUSCH, then only 2-symbol PUCCH is transmitted. Other UCI on PUCCH and PUSCH may be sent on PUCCH of 2-symbol.

When there is an overlap of transmission times of a plurality of PUCCHs and one or more PUSCHs, wherein the smallest TTI length is a PUSCH, only one PUCCH with the smallest TTI length among the plurality of PUCCHs is transmitted, and UCI on other PUCCHs or UCI of a specified type is transmitted on the PUCCH with the smallest TTI length. Relinquishing or deferring transmission of the remaining channels. Optionally, when there is UCI on PUSCH, transmitting the UCI or a specified type of UCI on PUCCH with the smallest TTI length. For example, there are 2-symbol PUSCH, 4-symbol PUCCH, 7-symbol PUCCH, and 1ms PUSCH, then only 4-symbol PUCCH is transmitted. Other UCI on PUCCH and PUSCH may be sent on PUCCH of 2-symbol.

Example four

Similar to the embodiments, in the present embodiment, on one carrier, there is a channel transmission method when there is an overlap between the agreed transmission times of the PUSCH and the PUCCH, where the TTI lengths corresponding to the two channels are different.

For this case, in the present embodiment, only the PUSCH is transmitted. Specifically, UCI on sPUCCH punctures the transmission on the interleaving matrix of PUSCH before the Discrete Fourier Transform (DFT) operation. Here, UCI on sPUCCH may also be referred to as covering a part of information on PUSCH in the interleaving matrix.

An example is given below. The transmission time corresponding to the PUSCH is a subframe n, and the transmission time corresponding to the sPUCCH is the first two transmission symbols on the subframe n, so in the interleaving matrix of the PUSCH, the columns corresponding to the first two transmission symbols are covered by UCI on the sPUCCH.

Optionally, the UCI on the sPUCCH may occupy data on the interleaving matrix corresponding to the transmission symbol corresponding to the sPUCCH. For example, the interleaving matrix of PUSCH is (R)_mux×C_mux) Matrix of R_muxIs the number of lines, C_muxIs the number of columns, as shown in fig. 4. In FIG. 4, each element in the interleaving matrix is interleavedy _i(i is an integer of 0 to i (R'_mux×C_mux-1)) is 1 column (Q)_m·N_L) A vector of rows. R'_mux＝R_mux/(Q_m·N_L), wherein ,Q_mIs a modulation order, N_LIs the number of layers.The number of symbols for PUSCH transmission does not include symbols for transmitting DMRS, and does not include symbols for transmitting SRS if SRS is present.

Since the sPUCCH occupies the first two transmission symbols in the interleaving matrix, the sPUCCH covers the information of the PUSCH on the columns corresponding to the first two symbols in the interleaving matrix, that is, covers the first two columns. As shown in fig. 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; and when the transmission symbol corresponding to the sUCCH and the transmission symbol corresponding to the DMRS of the PUSCH are overlapped, the DMRS of the PUSCH is still transmitted on the transmission symbol corresponding to the DMRS of the PUSCH. And the sPUCCH is only transmitted on the symbols corresponding to other sUCCHs except the transmission symbol of the DMRS.

Optionally, the number of resources occupied by UCI on sPUCCH is configured by the eNB, for example, parameters in a formula for calculating the number of resources occupied by sPUCCH are configured by the eNB.

Optionally, when the UCI on the sPUCCH is written into the interleaving matrix of the PUSCH, writing is performed in a preset manner, such as writing row by row from top to bottom, or writing row by row from bottom to top, and so on.

Optionally, UCI on sPUCCH may be sent on all transport blocks of PUSCH or may also be sent on one of 2 transport blocks of PUSCH. In an embodiment, UCI on the sPUCCH is transmitted on a transport block with a large Modulation and Coding Scheme (MCS) index value, and when MCS index values of two transport blocks are the same, the UCI may be transmitted on a preset transport block, such as the first transport block.

Alternatively, when transmitting in 1 transport block of PUSCH, it may be transmitted on all layers corresponding to the transport block, or on a partial layer. Such as repeating the transmission on all layers on the transport block of the PUSCH.

Optionally, when the PUSCH includes the UCI, the UCI information in the sPUCCH should be written to skip the information corresponding to the UCI on the PUSCH.

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 the at least one of RI/CRI and CQI/PMI, that is, the information of the PUSCH is covered outside part or all of the information of the at least one of RI/CRI and CQI/PMI, that is, rate matching is performed outside part or all of the information of the at least one of RI/CRI and CQI/PMI.

Optionally, when there is HARQ-ACK on PUSCH, the HARQ-ACK performs puncturing after writing the information of sPUCCH in the interleaving matrix.

Optionally, the UCI on the sPUCCH may use an independent modulation and coding scheme, or may use the same modulation and coding scheme as that of the PUSCH.

In practical application, when there is an overlap between the transmission times of PUSCHs with more than two TTI lengths, the above method may be similarly employed. In order to ensure the time delay performance of the PUCCH with the shorter TTI length, the PUSCH and the PUCCH with the shortest TTI length are processed according to the method. For example, in fig. 3, sPUCCH with 2 transmission symbols and sPUSCH with 4 transmission symbols are processed according to the method in this embodiment. The 1ms PUSCH relinquishes transmission.

When there are multiple PUCCHs and one or multiple PUSCHs with overlapping transmission time, only the PUSCH with the shortest TTI length in the multiple PUSCHs can be transmitted, and the rest channels give up transmission or defer transmission. Optionally, when the TTI length of only one PUCCH is smaller than the TTI length of the PUSCH with the shortest TTI length among the PUSCHs, the UCI on the PUCCH or the UCI of the designated type is transmitted on the PUSCH with the shortest TTI length among the PUSCHs, and the transmission method is the same as that in the embodiment. Optionally, when the TTI length of the plurality of PUCCHs is smaller than the TTI length of the PUSCH with the shortest TTI length among the plurality of PUSCHs, transmitting UCI on the plurality of PUCCHs or UCI of the specified type on the PUSCH with the shortest TTI length among the plurality of PUSCHs. The transmission position may be a symbol corresponding to a PUCCH having the shortest TTI length among the plurality of PUCCHs. As shown in fig. 6. And the appointed transmission time of four channels is overlapped, wherein the PUSCH with the shortest TTI length in the PUSCH is the 7-symbol sUSCH, the 7-symbol sUSCH is transmitted, and the other channels give up transmission. The PUCCH shorter than the TTI length of 7-symbol has two, i.e., 4-symbol sPUCCH and 2-symbol sPUCCH, and UCI on these two channels is written to 7-symbol sPUSCH at the position of the symbol corresponding to the PUCCH of the shortest TTI length of 4-symbol sPUCCH and 2-symbol sPUCCH, i.e., symbols #12 and 13, i.e., mesh portion.

EXAMPLE five

Similar to the embodiment, in the present embodiment, on one carrier, there is a channel transmission method when there is an overlap between the agreed transmission times of the PUSCH and the PUCCH, where the lengths of the corresponding TTIs of the two channels are different.

In this embodiment, only the sPUCCH is transmitted and the PUSCH is not transmitted on the symbol corresponding to the sPUCCH, and the PUSCH is still transmitted on the remaining symbols corresponding to the PUSCH. As shown in fig. 7, fig. 7 shows 14 transmission symbols in one subframe, where sPUCCH occupies symbols #6 and #7, and the slashed portion is DMRS. In the method, the frequency domain resources corresponding to the sPUCCH and the PUSCH may be overlapped, or non-overlapped or partially overlapped.

That is to say, the PUSCH is not transmitted on the transmission symbol where the sPUCCH is located, and the information of the remaining PUSCH other than the transmission symbol where the sPUCCH is located is still transmitted.

And when the PUSCH contains the UCI, putting the UCI on the sPUCCH for transmission. Or, when the PUSCH contains the UCI and the symbol where the UCI is located is overlapped with the symbol corresponding to the sPUCCH, the UCI is put on the sPUCCH for transmission.

Optionally, if the UCI includes HARQ-ACK, the HARQ-ACK is put on sPUCCH for transmission, and if the UCI also includes other information, transmission of the other information is abandoned.

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

Optionally, when the overlapping portion of the sPUCCH and the PUSCH contains a 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 may be generated from the lowest frequency to the highest frequency of the two.

In practical application, when there is UCI on PUSCH, transmission may be performed by using one of the following methods:

the first mode is as follows: and completely not considering the position relation between the transmission symbol corresponding to the sPUCCH and the transmission symbol corresponding to the UCI of the PUSCH, and if the UCI exists on the PUSCH, the UCI is transmitted on the sUCCH.

Optionally, if the UCI includes HARQ-ACK, the HARQ-ACK is placed on sPUCCH for transmission, and if the UCI also includes other information, the other information is abandoned from transmission.

Optionally, if the UCI includes HARQ-ACK and/or RI/CRI, the HARQ-ACK and/or RI is placed on sPUCCH for transmission, and if the UCI also includes other information, transmission of the other information is abandoned.

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

The second mode is as follows: when UCI exists 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 put on the sPUCCH for transmission; when there is no overlap with the UCI, the UCI is still placed on the PUSCH.

Here, the overlapping of the 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 where the HARQ-ACK and/or CSI are located, the HARQ-ACK and/or CSI is placed on the sPUCCH. As shown in fig. 8, when sPUCCH corresponds to the first two transmission symbols, if an RI happens to be sent on the PUSCH, the RI is put on the PUSCH for transmission.

The third mode is as follows: when the transmission symbol corresponding to the sPUCCH and the transmission symbol corresponding to all or part of the UCI information overlap, the sPUCCH is still transmitted on the overlapped transmission symbol.

The fourth mode is that: and when the transmission symbol corresponding to the sPUCCH is overlapped with the transmission symbol corresponding to all or part of the UCI information, the sUCCH is postponed to a position where the sUCCH does not collide with the UCI. Such as postponing until the next sTTI without UCI information.

In practical application, when the symbols corresponding to the sPUCCH and the DMRS of the PUSCH overlap, the following transmission may be used:

the first mode is as follows: the sPUCCH is transmitted on the transmission symbol where the DMRS is located, and the DMRSs on the remaining other symbols may be used to demodulate the PUSCH, for example, the sPUCCH may be used in the first slot, and the DMRS on the second slot may be used to demodulate the PUSCH.

The second mode is as follows: and generating a DMRS according to the frequency domain span of the sUCCH and the PUSCH. As shown in fig. 9. The transmission symbols corresponding to sPUCCH are symbols #2 and # 3, and overlap with the DMRS symbol of the first slot, and at this time, one DMRS is generated according to the frequency domain span of PUSCH and sPUCCH, that is, one DMRS is generated from the lowest frequency to the highest frequency of both. The time domain position of the DMRS may be a transmission symbol where the DMRS of the PUSCH is located, or may be a transmission symbol where the sPUCCH is located, and the time domain position of the DMRS in fig. 9 is a symbol where the DMRS is located.

The above method can be similarly applied when there is an overlap of the transmission times of channels with more than two TTI lengths. In order to guarantee the time delay performance of the channel with the shorter TTI length, the PUSCH and the PUCCH with the shortest TTI length are processed according to the method. For example, in fig. 3, the sPUSCH with 2 transmission symbols and the sPUCCH with 4 transmission symbols are processed according to the method in this embodiment.

Or, when there is an overlap in transmission times of channels having a length exceeding 2 TTIs, only a designated channel is transmitted on one transmission symbol, wherein,

the specified channel satisfies one of the following conditions:

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

and in the more than two channels, the appointed transmission time of a plurality of channels comprises the transmission symbol, and the TTI length corresponding to the appointed channel is the minimum in the plurality of channels.

Fig. 10 shows a schematic diagram, where there is an overlap of the agreed transmission times of the PUSCHs with three TTI lengths, which are 1ms PUSCH, 4 symbol sPUCCH and 2 symbol sPUCCH, where the agreed transmission time of the PUSCH with 1ms is symbols #0 to 13, the agreed transmission time of the sPUCCH with 4 symbols is symbols #5 to 8, and the agreed transmission time of the sPUCCH with 2 symbols is symbols #7 and # 8. Then, only 2 symbols of sUCCH are transmitted on symbols #7 and 8, only 4 symbols of sUCCH are transmitted on symbols #5 and 6, and only 1ms of PUSCH is transmitted on the remaining symbols, i.e., symbols # 0-4 and 9-13.

The processing of UCI is similar to that described above, such as all UCI on PUSCH and sPUCCH or a specified type of UCI is transmitted on sPUCCH. Or only the knocked-down UCI or the knocked-down specified type of UCI is transmitted on the sPUCCH.

EXAMPLE six

The embodiment provides a channel transmission method when the appointed transmission time of the PUSCH and the PUCCH is overlapped on one carrier, wherein the TTI lengths corresponding to the two channels are different. Here, the length of the TTI may be 1ms TTI in the existing LTE system, or the TTI includes 2 transmission symbols, 4 transmission symbols, or 7 transmission symbols, etc. 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 for the PUSCH is transmitted on the first transmission symbol in a subframe, and the uplink data is transmitted on the third transmission symbol in the subframe. The length of TTI in practical application is not limited to the TTI length described in this embodiment. In this embodiment, the TTI with a length less than 1ms is also referred to as 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 1ms, and 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. This embodiment takes as an example a scenario in which the transmission times of the PUCCH of the 1ms TTI and the sPUSCH of the sTTI overlap. The method in this embodiment may also be used in application scenarios with other TTI lengths.

The UCI on PUCCH includes at least one of CSI, SR, and HARQ-ACK. And sending the sUSCH and abandoning transmission of the PUCCH. Optionally, the UCI on the PUCCH is put on sPUSCH for transmission, or the specified UCI on the PUCCH is put on sPUSCH for transmission. The details are as follows.

Optionally, if the UCI contains the SR, the SR is placed on the sPUCCH for transmission, and if the UCI also contains other information, the other information is abandoned from transmission.

Optionally, if the UCI includes HARQ-ACK and/or SR, the HARQ-ACK and/or SR is placed on sPUCCH for transmission, and if the UCI also includes other information, transmission of the other information is abandoned.

Optionally, if the UCI includes at least one of HARQ-ACK, SR and CSI of a preset type, at least one of HARQ-ACK, SR and CSI of a preset type is placed on the sPUCCH for transmission, and transmission of other information is abandoned. Here, the preset type of CSI may be wideband CSI, and is not limited to this form of CSI in practical applications.

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

Other information on the PUCCH than that put on the sPUSCH for transmission abandons transmission.

Optionally, information on the PUCCH that is relinquished to transmission is postponed to a later subframe.

The method in this embodiment may also be used when there is an overlap in the agreed transmission times of more than 2 channels. When the shortest TTI length among the multiple uplink channels is the PUSCH, UCI on other PUCCH channels or UCI of a specified type is transmitted on the PUSCH, similarly as described above. Optionally, on other PUSCH channels, if there is also UCI information, these UCI may also be transmitted on the sPUSCH. Here, when the sPUSCH also includes UCI, the UCI may be transmitted in a cascade manner with the UCI on the sPUSCH.

EXAMPLE seven

Similar to the sixth embodiment, this embodiment provides a channel transmission method when there is an overlap between the agreed transmission times of the PUSCH and the PUCCH on one carrier, where the TTI lengths corresponding to 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, a scenario in which transmission times of the PUCCH of the 1ms TTI and the sPUSCH of the sTTI overlap is taken as an example to illustrate, and the method in this embodiment may also be used in an application scenario with other TTI lengths.

In this embodiment, the PUCCH and the sPUSCH are transmitted simultaneously, that is, the UE transmits 2 channels simultaneously on the transmission symbol where the sPUSCH is located.

And the frequency domain resources corresponding to the PUCCH and the sUSCH are not overlapped.

The method can also be used for simultaneously transmitting all channels when the appointed transmission time of more than one PUCCH and more than one PUSCH are overlapped and the corresponding frequency domain resources are not overlapped.

Example eight

This embodiment provides a transmission method when there is an overlap of the agreed transmission times of multiple PUCCHs on one carrier, where the TTI lengths corresponding to the multiple PUCCHs are different.

This embodiment takes as an example a scenario in which the transmission times of the PUCCH of the 1ms TTI and the sPUCCH of the sTTI overlap. The method in this embodiment may 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 transmits two channels.

And the frequency domain resources corresponding to the PUCCH and the sPUCCH are not overlapped.

Example nine

This embodiment provides a channel transmission method when the agreed transmission times of a plurality of PUCCHs are overlapped on one carrier. Wherein the plurality of PUCCHs differ in corresponding TTI length.

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

Several transmission modes are given below, and one of the following methods can be adopted for transmission:

the first mode is as follows: and sending the sPUCCH, and abandoning the transmission of the PUCCH or postponing the PUCCH to a following subframe for transmission.

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

Optionally, if the UCI includes HARQ-ACK, the HARQ-ACK is placed on sPUCCH for transmission, and if the UCI also includes other information, the other information is abandoned from transmission. And if the UCI does not contain the HARQ-ACK, only sending the information contained in the sPUCCH on the sUCCH.

Optionally, if the UCI contains the SR, the SR is placed on the sPUCCH for transmission, and if the UCI also contains other information, the other information is abandoned from transmission. And if the UCI does not contain the SR, only sending the information contained in the sPUCCH on the sUCCH.

Optionally, if the UCI includes HARQ-ACK and/or SR, the HARQ-ACK and/or RI is placed on sPUCCH for transmission, and if the UCI also includes other information, transmission of the other information is abandoned. For example, when the UCI has HARQ-ACK and SR and CQI/PMI, the HARQ-ACK and SR may be put on the sPUCCH for transmission, and the CQI/PMI abandons the transmission.

Optionally, if the UCI includes at least one of HARQ-ACK, SR and CSI of a preset type, at least one of HARQ-ACK, SR and CSI of a preset type is transmitted on the sPUCCH, and transmission of other information is abandoned. Here, the preset type of CSI may be some format of CSI, such as wideband CSI. For example, when the UCI has HARQ-ACK and SR and narrowband CSI thereof, the HARQ-ACK and SR may be put on the narrowband sPUCCH for transmission, and the narrowband CSI gives up 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, HARQ-ACK bundling technique may be employed.

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

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

Optionally, which of the above manners is adopted may be determined according to the TTI length corresponding to the sPUSCH.

Optionally, the eNB may configure the UE whether sPUCCH and PUCCH may be transmitted simultaneously. If the configuration is that simultaneous transmission is possible, the method in the eighth embodiment is adopted for transmission, otherwise, one mode in the present embodiment is adopted for transmission.

Example ten

In the CA scenario, the present embodiment provides a channel transmission method when there is an overlap between agreed transmission times of one or more PUCCHs and one or more PUSCHs. Wherein, the TTI lengths of the one or more PUCCHs are different, and the appointed transmission time of the one or more PUSCHs is different.

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

For the remaining PUCCHs, i.e., no PUSCH of the same TTI length as the remaining PUCCHs, the remaining PUCCHs are transmitted on a designated PUSCH, for example, on a PUSCH on the primary carrier if there is a PUSCH on the primary carrier, or on a carrier in which scellndex is minimum or maximum if there is no PUSCH on the primary carrier. Or selecting the PUSCH with the minimum TTI length for transmission.

An example is given below, there are 2 carriers in total, scellndex is 0 and 1 respectively, and there is one PUSCH on each carrier, where the TTI length of the PUSCH on the carrier with scellndex 0 is 4, the TTI length of the PUSCH on the carrier with scellndex 1 is 2, there are three PUCCHs at this time, and the TTI lengths are 2, 4, and 7 respectively, then information on the PUCCH with TTI length 2 is transmitted on the carrier with scellndex 1, and information on the PUCCH with TTI length 2 is transmitted on the carrier with scellndex 0. The PUCCH with TTI length 7 may be transmitted on the PUSCH with the shortest TTI, i.e., on the carrier with scellIndex of 1. The manner of transmission can refer to the foregoing embodiments.

EXAMPLE eleven

Wherein, the TTI lengths of the one or more PUCCHs are different, and the appointed transmission time of the one or more PUSCHs is different.

In this embodiment, when there is an overlap between the agreed transmission times of one or more PUCCHs and one or more PUSCHs, all PUSCHs and one PUCCH are transmitted. Wherein a TTI length of the transmitted PUCCH among the plurality of PUCCHs is shortest. Optionally, the transmitted PUCCH is transmitted on a primary carrier.

Optionally, in the plurality of PUCCHs, UCI on a PUCCH other than the PUCCH having the shortest TTI length or specific information of UCI is transmitted on the transmitted PUCCH channel, such as only HARQ-ACK is transmitted on the transmitted PUCCH.

Example twelve

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

And for the rest PUCCHs, namely PUSCHs which are not as long as the TTI length of the rest PUCCHs, selecting the PUCCH with the smallest TTI from the rest PUCCHs for transmission, and transmitting all or part of information on other PUCCHs in the PUCCHs with the smallest TTI. That is, all PUSCHs and one PUCCH are transmitted.

An example is given below, there are 2 carriers in total, scellndex is 0 and 1 respectively, and there is one PUSCH on each carrier, where the TTI length of the PUSCH on the carrier with scellndex 0 is 4, the TTI length of the PUSCH on the carrier with scellndex 1 is 2, there are three PUCCHs at this time, and the TTI lengths are 2, 4, and 7 respectively, then information on the PUCCH with TTI length 2 is transmitted on the carrier with scellndex 1, and information on the PUCCH with TTI length 2 is transmitted on the carrier with scellndex 0. PUCCH of TTI length 7 is transmitted separately. That is, a PUCCH of TTI length 7 and two PUSCHs of TTI lengths 2 and 4, respectively, are transmitted.

EXAMPLE thirteen

Determining the priority based on at least one of:

1) the priority of the PUCCH carrying the HARQ-ACK is higher than that of the PUCCH carrying the CSI, namely when two PUCCHs, one carrying the HARQ-ACK and the other carrying the CSI, the PUCCH carrying the HARQ-ACK is transmitted, and the PUCCH carrying the CSI is abandoned.

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

3) Under the condition that the carried UCI types are the same, the priority of the PUCCH with the short TTI length is higher than that of the PUCCH with the long TTI length, for example, the PUCCH with the 1ms TTI length and the PUCCH with the 0.5ms length both carry HARQ-ACK, and then the priority of the PUCCH with the 0.5ms length is higher.

4) The PUCCH with the short TTI length carrying the HARQ-ACK and/or SR has higher priority than the PUCCH with the long TTI length carrying the HARQ-ACK and/or SR.

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