Description

Information transmission method and terminal

Technical Field

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

Background

With the development of mobile communication service demand, New wireless communication systems (i.e., 5G NR, 5Generation New RAT) are being researched in the future. In the 5G NR system, an important requirement is Low-delay and high-reliability communication, and transmission schemes such as URLLC (Ultra Reliable Low Latency communication) have appeared.

In the uplink transmission scheme of URLLC, in order to reduce delay, a scheduling-free scheme is adopted, and in order to increase reliability, sufficient resources need to be ensured.

In an FDD (Frequency Division Duplex) system, when PUSCH (Physical Uplink Shared Channel) transmission occupying L symbols at a time needs to cross a slot boundary, PUSCH (Physical Uplink Shared Channel) needs to be divided into two or more PUSCHs for transmission, and an OFDM (Orthogonal Frequency Division Multiplexing) symbol position to be occupied by each PUSCH transmission needs to be determined.

In a TDD (Time Division Duplex) system, a slot boundary and an uplink/downlink switching interval are processed, and when PUSCH transmission occupying L symbols at a Time needs to cross the slot boundary or the uplink/downlink switching interval, PUSCH transmission needs to be divided into two or more PUSCHs for transmission, and an OFDM symbol position to be occupied by each PUSCH transmission needs to be determined.

For a transport block TB, when a plurality of PUSCHs are divided for repeat/segment transmission, a Redundancy Version (RV) needs to be configured for each repeat/segment, and the selection of the RV needs to consider decoding performance and self-decodable performance, usually, systematic bits in encoding have a larger influence on the decoding performance and the self-decodable performance, check bits in encoding have a smaller influence on the decoding performance and the self-decodable performance, but better decoding performance can be achieved if the systematic bits and the check bits are matched in number proportion.

In the existing URLLC, for the RV configuration problem, the related technical solutions are as follows: according TO the current standard, through RRC (Radio Resource Control) configuration, for example, the number of times of repeated transmission K is 4, RV is { 0231 }, the time domain Resource position is { initial OFDM symbol, number of OFDM symbols }, the time domain Resource position is defined as one transmission opportunity TO, that is, the Resource position for completing one repeated transmission, and K4 means that four TOs are required for performing four repeated transmissions. When data is transmitted on the first TO, RV ═ 0 is used; when data is transmitted on the second TO, RV 2 is used; when data is transmitted on the third TO, RV — 3 is used; when data is transmitted on the fourth TO, RV 1 is used.

In fig. 1, for a PUSCH transmission with a length L, when the PUSCH transmission needs to cross a slot boundary or an uplink-downlink switching interval, the PUSCH transmission is divided into two transmissions. If N symbols are occupied before the time slot boundary or the uplink and downlink conversion interval, L-N symbols are occupied after the time slot boundary or the uplink and downlink conversion interval, and N or L-N is not limited. When the lengths of the respective repetitions/segments are different, how the RVs of the respective repetitions/segments are configured, there is no solution at present.

Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

As shown in fig. 2, an embodiment of the present invention provides an information transmission method, which is applied to a terminal, and the method includes:

step 21, acquiring configuration information of a Physical Uplink Shared Channel (PUSCH) for transmission; the configuration information at least includes: and transmitting the time domain resource information and RV configuration information of the PUSCH. Of course, other information, such as DMRS (Demodulation Reference signal) configuration information, may also be included. Specifically, when the configuration information is acquired, at least one of a Downlink Control Information (DCI) signaling, a Radio Resource Control (RRC) signaling, and a Physical Downlink Control Channel (PDCCH) sent by the network device may be received; and acquiring configuration information for transmitting the PUSCH from at least one of the DCI signaling, the RRC signaling and the PDCCH.

Step 22, when the PUSCH is repeatedly/sectionally transmitted, obtaining redundancy versions RV respectively corresponding to the repeated/sectionally transmitted at least two PUSCHs according to the length of the repeated/sectionally transmitted PUSCH and the configuration information;

and step 23, transmitting the PUSCH according to the RV.

According to the embodiment of the invention, when the PUSCH is subjected to repeated/segmented transmission, the redundancy versions RV respectively corresponding to the repeated/segmented transmission of at least two PUSCHs are obtained according to the obtained configuration information, and the PUSCH is transmitted according to the RV, so that the reliability of data transmission is improved.

In an embodiment of the present invention, step 22 may specifically include:

step 221, obtaining the length of each repeated/segmented transmission of the PUSCH according to the time domain resource information of the PUSCH and the time slot boundary or the uplink and downlink switching time;

as shown in fig. 3, the terminal determines a slot boundary or a position of TDD uplink/downlink (UL/DL) transition, and the terminal determines whether to transmit once or multiple times and a length of each repetition/segmentation transmission according to a time domain resource required to be occupied by PUSCH and the slot boundary or the position of TDD uplink/downlink transition, where the length of each repetition/segmentation transmission is determined by the number of symbols occupied by each repetition/segmentation transmission, where the symbols are, for example, OFDM (Orthogonal Frequency Division Multiplexing) symbols.

Step 222, dividing the PUSCH into N repetitions/segments according to the length of each repetition/segment transmission of the PUSCH, where N is an integer greater than or equal to 2;

step 223, obtaining redundancy versions RV corresponding to the at least two repeated/segmented transmissions of the PUSCH according to the length of the repeated/segmented transmission of the PUSCH and the RV configuration information.

Specifically, one implementation of this step 223 may include:

step 2231, if the RV sequence in the RV configuration information includes M RVs, the RV corresponding to the 1 st repetition/segment of the PUSCH is 0, and the length of the ith repetition/segment is greater than the length of the repetition/segment whose previous RV is 0, the RV corresponding to the ith repetition/segment is 0, and the i +1 th repetition/segment to the nth repetition/segment correspond to the 2 nd to mth RVs in the RV sequence, respectively, and i is (2, 3, …, N) in the RV sequence according to the order of the RVs in the RV sequence. Here, according to this method, all repetitions/segments of the PUSCH are determined, and RV association is performed for each repetition/segment.

For example, the gNB (network device, e.g., base station) notifies the UE of resource configuration, DMRS configuration, RV configuration, etc. through RRC signaling and/or activating PDCCH, so as to let the UE start PUSCH uplink transmission. Assume that the RV sequence in the RV configuration information is { 0231 }.

Due to the slot boundary or TDD uplink and downlink switching, a PUSCH transmission needs to be divided into four (or multiple) PUSCH transmissions or four PUSCH segments, and the four repeated transmissions or four PUSCH segments are seg1, seg2, seg3 and seg4, respectively. The method is also applicable when N and M are not equal;

for the PUSCH transmission or PUSCH segmentation before the time slot boundary or TDD uplink and downlink switching time to seg1, the PUSCH transmission or PUSCH segmentation after the time slot boundary or TDD uplink and downlink switching time to seg2, seg3 and seg 4;

according to the method of this embodiment, the RV corresponding to seg1 is 0, if the length of seg2 is greater than seg1, the RV corresponding to seg2 is 0, and the RVs corresponding to seg3 and seg4 are 2 and 3, respectively, that is, the RV 2 is greater than the PUSCH transmission/segmentation for which the previous RV is 0, the RV corresponding to seg2 is 0, that is, the first RV in the RV sequence, seg3 and seg4 reset their corresponding RVs in turn according to the RV order in the RV sequence, that is, the RVs corresponding to seg3 and seg4 are 2 and 3, respectively;

and comparing the lengths of seg3 and seg2 in sequence, if the length is larger than the length, setting the RV corresponding to seg3 to be 0, setting the RV corresponding to seg4 to be 2, and if the length of seg3 is smaller than the length of seg2, setting the RV corresponding to seg3 to be 2 and keeping the RV unchanged.

Another implementation of this step 223 may include:

step 2232, if the RV sequence in the RV configuration information includes M RVs, the RV corresponding to the 1 st repetition/segment of the PUSCH is 0, and the length of the ith repetition/segment is greater than the length of the repetition/segment whose previous RV is 0, the RV corresponding to the ith repetition/segment is 0, and i is (2, 3, …, N), where all repetitions/segments of the PUSCH are determined according to this method, and RV corresponding is performed for each repetition/segment.

For example, the gNB notifies the UE of resource configuration, DMRS configuration, RV configuration, and the like through RRC signaling and/or activation of the PDCCH, and allows the UE to start PUSCH uplink transmission. Assume that the RV sequence in the RV configuration information is { 0231 }.

according to the method of this embodiment, the RV corresponding to seg1 is 0, if the length of seg2 is greater than seg1, the RV corresponding to seg2 is 0, and seg3 and seg4 respectively keep the original corresponding RVs unchanged, that is, the RV corresponding to seg3 is 3, and the RV corresponding to seg4 is 1;

if the length of seg3 is greater than seg2, the RV corresponding to seg3 is set to 0, otherwise, the RV is kept unchanged

Yet another implementation of this step 223 may include:

step 2233, if the RV sequence in the RV configuration information includes M RVs, the N repetitions/segments of the PUSCH are arranged in a sequence from long to short, and correspond to one RV according to the sequence of the RVs in the RV sequence.

For example, the gNB notifies the UE of resource configuration, DMRS configuration, RV configuration, and the like through RRC signaling and/or activation of a PDCCH (physical downlink control channel), so that the UE starts PUSCH uplink transmission. Assume that the RV sequence in the RV configuration information is { 0231 }.

according to the method of this example, all segs are sorted from long to short, resulting in a sequence seg2> seg1> seg4> seg 3. Then the RV is determined for the sorted repeats/segments, and the RV for seg1, seg2, seg3, seg4 is 2, 0, 1, 3 in that order.

Yet another implementation of this step 223 may include:

step 2234, if the RV sequence in the RV configuration information includes M RVs, when N is greater than M, determining a first target RV sequence, where the first target RV sequence includes L × M RVs, and the L RV sequences are sequentially arranged, and the N repetitions/segments of the PUSCH are arranged according to a sequence from long to short, and correspond to one RV according to the sequence of the RVs in the first target RV sequence; l is an integer greater than or equal to 1.

Due to the slot boundary or TDD uplink and downlink switching, a PUSCH transmission needs to be divided into four (or multiple) PUSCH transmissions or four PUSCH segments, and the four repeated transmissions or four PUSCH segments are seg1, seg2, seg3 and seg4, respectively.

And one-time PUSCH transmission is divided into 8-time PUSCH transmission or PUSCH segmentation, namely seg 1-8, and all segs are sorted from long to short to obtain a sequence of seg2> seg1> seg5> seg6> seg4> seg3> seg8> seg 7. When the RV is determined for the sorted repetitions/segments, the corresponding RV sequence is formed by cascading a plurality of signaled RV sequences, namely { 02310231 }, so the RVs of seg2, seg1, seg5, seg6, seg4, seg3, seg8, and seg7 are 02310231 in sequence.

Yet another implementation of this step 223 may include:

step 2235, if the RV sequence in the RV configuration information includes M RVs, when N is greater than M, and after sorting according to length, the first M repetitions/segments of the N repetitions/segments of the PUSCH respectively correspond to one RV according to the sequence of RVs in the RV sequence, and the M +1 th to N th repetitions/segments of the PUSCH respectively correspond to one RV according to the sequence of RVs corresponding to the first M repetitions/segments.

And one PUSCH transmission is divided into 8 PUSCH transmissions or PUSCH segments, namely segs 1-8, and all segs are sorted from long to short to obtain a sequence of seg2> seg1> seg4> seg 3. Then when determining RV for the sorted repeats/segments, RV of seg1, seg2, seg3, seg4 is sequentially 2, 0, 1, 3, and RV of seg5, seg6, seg7, seg8 is also sequentially 2, 0, 1, 3, where seg5, seg6, seg7, seg8 are no longer sorted by length.

In the above embodiments of the present invention, when the lengths of the two repetitions/segments of the PUSCH are the same, the two repetitions/segments of the PUSCH are arranged in sequence according to the order of time.

In one embodiment of the invention, the RV value of the repetition/segmentation after the time slot boundary or the uplink and downlink switching time is determined according to the RV value of the repetition/segmentation before the time slot boundary or the uplink and downlink switching time; for example, the RV values of two repetitions/segments before and after the slot boundary or the time of the uplink/downlink transition may be the same or different. As shown in fig. 3, the RV values of the two repetitions/segments (seg1 and seg2) before and after the slot boundary or the time of the uplink/downlink transition are the same or different.

Correspondingly, the RV values of the two repetitions/segments before and after the time slot boundary or the uplink and downlink switching time are the same, and the two repetitions/segments before and after the time slot boundary or the uplink and downlink switching time respectively select the coded bit output corresponding to the RV according to the corresponding RVs, or sequentially select the coded bit output corresponding to the RV according to the lengths of the two repetitions/segments before and after the time slot boundary or the uplink and downlink switching time.

For example, the RVs corresponding to seg1 and seg2 shown in fig. 3 are both 2, then seg1 and seg2 both select their coded bit outputs according to the value of RV being 2, and when their coded bit outputs are selected, seg1 occupies 4 symbols (i.e. length is 4) and seg2 occupies 10 symbols (i.e. length is 10), assuming that each 10 coded bits occupy 1 symbol (1 or more RBs in frequency domain), 140 coded bits can be selected according to the value of RV being 2, where seg1 selects the first 40 bits (e.g. bit 0 to bit 39) of 14 coded bits, and seg2 selects the first 100 bits (e.g. bit 0 to bit 99) of 14 coded bits; on the base station side, the base station obtains seg1 and then performs primary decoding according to RV 2, the base station obtains seg2 and then performs secondary decoding according to RV 2, and the base station can also perform soft combining with seg1 according to RV 2 and then performs primary decoding after obtaining seg 2.

For another example, the RVs corresponding to seg1 and seg2 shown in fig. 3 are both 2, then seg1 and seg2 both select their coded bit outputs according to the value of RV being 2, and when their coded bit outputs are selected, seg1 occupies 4 symbols (i.e., length is 4) and seg2 occupies 10 symbols (i.e., length is 10), and assuming that each 10 coded bits occupy 1 symbol (1 or more RBs in the frequency domain), 140 coded bits can be selected according to the value of RV being 2, where seg1 selects the first 40 bits (e.g., bit 0 to bit 39) of 140 coded bits, and seg2 selects the last 100 bits (e.g., bit 40 to bit 139) of 140 coded bits. At the base station side, after obtaining seg1 and seg2, the base station performs tandem concatenation to obtain a new repeated/segmented segN, and performs decoding once according to RV 2.

Wherein, in the case that RVs corresponding to respective PUSCH repetitions/segments are determined in chronological order, or in the case that RVs corresponding to respective PUSCH repetitions/segments are determined according to lengths of PUSCH repetitions/segments in the above embodiment of the present invention, when there are a plurality of PUSCH repetitions/segments with RV of 0 and the system allows PUSCH transmission to start from any PUSCH repetition/segment with RV of 0, the 1 st repetition/segment at which PUSCH transmission starts is determined according to the first condition and the second condition, or is determined according to the first condition and the third condition; the first condition is that the RV of the repeat/segment is 0; the second condition is that the repeated/segmented data is not a time slot boundary or repeated/segmented data after the uplink and downlink switching time if the repeated/segmented data belongs to the repeated segmented data obtained by segmentation; the third condition is that the repeat/segment transmission does not belong to a segmented repeat/segment.

For another example, RV corresponding to seg1 (which may be PUSCH-repetition) and seg2 (which may be PUSCH-repetition) shown in fig. 3 is 0, then seg1 and seg2 both select their coded bit outputs according to RV value being 0, and when their coded bit outputs are selected, seg1 occupies 4 symbols (i.e., length is 4) and seg2 occupies 10 symbols (i.e., length is 10), assuming that each 10 coded bits occupies 1 symbol (1 or more RBs in frequency domain), 140 coded bits may be selected according to RV value being 0, where seg1 selects the first 40 bits (e.g., bits 0 to 39) of 140 coded bits, and seg2 selects the last 100 bits (e.g., bits 40 to 139) of 140 coded bits. At the base station side, after obtaining seg1 and seg2, the base station performs tandem concatenation to obtain a new repeated/segmented segN, and performs decoding once according to RV of 0.

When determining whether seg1 and seg2 can be the first transmitted repeated/segmented transmission in two repeated/segmented transmissions corresponding to one PUSCH transmission, two conditions need to be judged, the first condition is that the RV of the repeated/segmented transmission is 0, and at this time, the RVs of seg1 and seg2 are both 0, namely both the first condition is met; the second is that the repetition/segmentation transmission cannot be the repetition/segmentation after the timeslot boundary or the uplink/downlink switching time if the repetition/segmentation transmission belongs to the segmented repetition segmentation transmission, where seg2 is the repetition/segmentation after the segmented timeslot boundary or the uplink/downlink switching time, and seg1 is not, so seg1 may be transmitted as the first transmitted repetition/segmentation, and seg2 may not be transmitted as the first transmitted repetition/segmentation. If the second condition is that the repetition/segment transmission does not belong to a segmented repetition/segment, neither seg1 nor seg2 can be transmitted as the first transmitted repetition/segment. The first transmitted repeated/segmented transmission here means that the transmission of the entire PUSCH is started.
