Description

[Technical field]

[0001] This application is a joint venture with Chinese Patent Application No. 201810482650 filed on May 18, 2018. This application claims priority from application Ser. No. 09 / 023,363, filed on May 23, 2009, the entire contents of which are incorporated herein by reference. It is assumed that.

[0002] The present disclosure relates to the field of communications, and in particular to a channel setting method and a terminal, a storage medium, Regarding child devices. [Background technology]

[0003] In the prior art, multiple UEs of one user device physical channels (e.g., one or more physical uplink control channels Uplink Control Channel (PUCCH) and / or one More than one Physical Uplink Shared Channel The time domain is In each of these, one or more orthogonal frequency division multiplexing (OFDM) OFDM (Orthogonal Frequency Division Multiplexing) symbols. The plurality of physical channels overlap in the time domain in slots. overlapping (e.g., full or partial overlap of OFDM symbols) may occur. In particular, when the plurality of physical channels are uplink physical channels, generally, Multiple physical channels cannot be transmitted simultaneously, and only one physical channel can be transmitted at a time. The physical channel to be finally transmitted is required not to be overloaded in the time domain. It may be one of several physical channels on which the wrap occurs.

[0004] Regarding overlapping of multiple channels in the time domain, FIG. Figure 1 shows the possible situations where two channels overlap in the time domain. FIG. 1 is a schematic diagram of a single P of a single UE, but is not limited to the one shown in FIG. The UCCH channel and one PUSCH have overlapping symbols in a slot. However, Figure 1 shows some possible time domain overlaps of the two channels (multiple If there is overlap between the channels, it will be overlap in the time domain. ).

[0005] In FIG. 1, one PUCCH and one PUSCH channel are used as an example (two identical Two or more channels may be used, but the overlap in the time domain of more than two channels is not allowed. In FIG. 1, PUCCH1 and PUCCH2 are two different physical channels. In the past, PUCCH was divided into five formats: The uplink control information to be carried is defined. There are many types of UCI (Hybrid Automatic Repeat Request Confirmation Information, UCI) (Hybrid Automatic Repeat Request, HARQ-AC K), Scheduling Request (SR), Channel Channel State Information (CSI) Because the channel status information is divided into CSI-1 and CSI-2, different formats and Combining the different types of UCIs, the situations are very diverse and here are the issues The above is merely an example for the purpose of illustration.

[0006] In the prior art, for multiple physical channels that overlap in the time domain, For the case where the physical channels have the same starting position, 3GPP TS38.213 The initiation sequence of these physical channels provides several solutions that are standardized in the field. We have not yet considered how to handle the case where the symbols are not aligned. However, if the above multiple physical channels satisfy a certain timeline relationship, If the problem can be solved by the solution means in the prior art, the problem is solved by the solution means in the prior art. If the problem cannot be solved by the technical solutions, it is suggested that further solutions should be provided. It is being done.

[0007] FIG. 2 shows a schematic diagram of one timeline, which is a prior art example of the present disclosure. The current timeline definition is, for example, It is still unclear which physical channel should be used to define the end of the timeline. For example, as shown in Fig. 1c, the timeline end time is the current time in Fig. 1. The time is defined as the start position of the earlier physical channel of the two physical channels shown in For example, the start position of PUCCH in Fig. 1c is defined as the timeline end time. Figure 2 shows the results based on the operating hypothesis provided by New Radio (NR). This is the definition of the timeline end time (at the 3GPP Ran1 92bis meeting). (This theory is derived from the operating hypothesis that

[0008] According to the operation hypothesis in the prior art, an example of the definition of the timeline end time is obtained ( In other cases, the definition of the timeline end time is the same.) In Figure 2, PUSCH and PU The CCH channel overlaps in the time domain and the PUSCH channel overlaps in the PUCC Since the timeline end time is earlier than the start position of the PUSCH channel, (See the dashed line in Figure 2.)

[0009] Currently, there is no effective solution to the above problems in the prior art. Summary of the Invention [Problem to be solved by the invention]

As shown, the apparatus includes: A determination module 6 for determining that a plurality of physical channels overlap in the time domain 0 and and a selection module 62 for selecting a designated channel for transmitting the transmission data.

[0041] Optionally, the determining module is adapted to determine whether one physical channel and a plurality of time division physical channels are present. A decision unit for deciding to overlap in the time domain is included.

[0042] Each of the above modules can be realized by software or hardware. In the latter case, the above modules are all located in the same processor, or Each module is realized in a form in which it is located on a different processor in an arbitrary combination. The following are examples of the present invention that may be used, but are not limited to these.

[0043] Example 3 In this embodiment, when multiple physical channels overlap in the time domain, To efficiently solve the data transmission problem, we use time domain overlapping. This provides a method for defining timeline end times.

[0044] The multiple physical channels of one UE are each one or more OFDM systems in the time domain. The above multiple physical channels are arranged in a time domain in a slot. If there is overlap in the time domain, the final The physical channel transmitted in the IEEE 802.11b mode may be another physical channel. The physical channel is not arranged for data transmission (originally, data transmission is arranged for If arranged, this other physical channel is included in the above multiple physical channels. Other physical channels may be used, resulting in overlapping physical channels in the time domain. The channel is a channel on which data transmission is arranged, but it is one of the multiple physical channels mentioned above. (which may not overlap in the time domain with the above) but other physical channels The time domain location of the physical channel is actually different in time domain from one or more of the physical channels. There may be overlapping of other physical channels among the above physical channels. It is possible that none of these overlap in the time domain.

[0045] The following is an example to illustrate the problems that may exist in the prior art, but other different physical channels may also be used. The same problem exists when the two overlap in the time domain, except that the physical channels are different. There is a possibility that.

[0046] FIG. 7 illustrates an example in which two PUCCHs overlap in the time domain according to an embodiment of the present disclosure. For example, the two PUCCH channels in FIG. If wrapping, PUCCH1 receives periodic CSI (CSI information is in the CSI part 1 and / or CSI patr2 (CS1-1 and CSI-2, respectively) PUCCH1 carries AN (indicating HARQ-ACK), and PUCCH2 carries AN (indicating HARQ-ACK). If the rule satisfies the timeline-related requirements (i.e., all transmissions are completed before the timeline end time), Any data to be sent should be prepared. If not, the data to be sent should be During transmission, the AN bit information in PUCCH2 and CSI bit information in PUCCH1 (here, AN and CSI are concatenated). The items will be transported after being tied in the correct order.

[0047] However, the total number of bits after concatenating the AN and CSI exceeds the transmission range of PUCCH1. If the physical channel is not available, it is necessary to select another physical channel (there is no rule for selecting the physical channel in the prior art). , see TS38.213). A PUCCH resource for one transmission (denoted PUCCH3). ) is newly selected, the start symbol of PUCCH3 and the start symbol of PUCCH1 are The PUCCH3 is also a PUCCH configured for the UE. The PUCCH resource may be a PUCCH resource in a PUCCH set.

[0048] In the prior art of this embodiment, a UE may be configured with one or more PUCCH sets. Alternatively, one or more PUCCH resources may be directly configured. If a PUCCH set is configured, one or more PUCCH resources are assigned to each PUCCH set. The start position of each PUCCH resource in a PUCCH set may be the same. The start of each PUCCH resource in the different PUCCH sets may be different. The positions may be the same or different, and may be different for different PUCCH sets. The range of the total number of bits carried on the PUCCH resource is the same, and the different PUCCH sets The range of the total number of bits carried on each PUCCH resource varies.

[0049] If PUUCH3 has the same starting symbol as PUCCH1, The overlap is transmitted without any problems using PUCCH3.

[0050] If the start position of PUCCH3 is earlier than the start position of PUCCH1, the timeline will be distorted. That is, according to the original timeline, it is possible that the start of PUCCH1 However, currently, PUCCH3 is faster than PUCCH1. ,The data to be transmitted is not prepared before the start of PUCCH3.,This is due to the timeline The end time is earlier than PUCCH1, which overlaps in the time domain according to the conventional technique. Therefore, the definition is currently based on the time domain. The overlap cannot be properly processed, which causes an error. In the current technique, two physical channels (PUCCH1 and P UCCH2) as the end point of the timeline. I don't think it's appropriate to consider that.

[0051] If the start position of PUCCH3 is later than the start position of PUCCH1, the data to be transmitted It is prepared in advance (before the start position of PUCCH3), and if you do this, it will not work. Obviously, the best starting point should be the start of PUCCH3, although this is not necessarily the case. The data to be transmitted must be prepared before the start of PUCCH3. , the timeline is not being utilized to its greatest efficiency.

[0052] In response to the above problems, the following provides means for solving the problems, including the following examples.

[0053] Example 1 The end of the timeline is defined as the start of the final physical channel to be transmitted. do.

[0054] Regarding the overlap in the time domain of multiple physical channels, where various time domain In the case of overlapping, a transmission rule for the corresponding data to be transmitted is given. The system then decides which physical channel to use according to the rules and assigns each overlapping Determines the processing of data in the channel. For example, in a, b, g, and h in Figure 1, Finally, the PUSCH channel is used for transmission, and the information in the PUCCH channel is transferred to the PUSCH The specific transmission rules can be referred to the prior art. Similar processing is done for l (lowercase L) and m in Figure 1, and generally, or select another physical channel for transmission ( There are specific selection rules, and you can refer to the TS 38.213 protocol.

[0055] Also, for example, the start of two physical channels that overlap in the time domain in FIG. For different locations, two overlapping physical channels are If the patent application satisfies the in-licensing relationship, it will be dealt with in the manner of related technology, or new means will be established in the future. It is being considered to calculate

[0056] That is, for multiple physical channels that overlap in the time domain, the base station and the UE , always depending on the specific overlapping physical channel situation, the final transmission In this case, the physical channel to be used can be determined.

[0057] Maximize timeline utilization and allow for more overlapping time domains. For efficient processing, i.e., in the time domain due to unreasonable setting of the timeline end time In order to avoid being unable to process some overlapping situations, the present embodiment For a UE, if multiple physical channels overlap in the time domain, It is proposed to define the line end time as the start of the final physical channel to be used. The physical channel that will ultimately be used is currently multiple overlapping channels in the time domain. The physical channel may be any of the following (this is determined based on existing rules): from physical channels other than the multiple physical channels overlapping in the time domain. (This can also be finally determined).

[0058] FIG. 8 is a schematic diagram of determining a timeline end time according to an embodiment of the present disclosure. Some examples are shown below. In Fig. 8a, the final one to be used is the current PUSCH channel. Since the timeline is a PUSCH, the timeline end time is defined as the start position of the current PUSCH. (The end result is the same as the timeline end position in the prior art.) Since the final one is the current PUSCH channel, the timeline end time is , is defined as the start position of the current PUSCH (the end result is (This is different from the end of the in-line position.)

[0059] In FIG. 8c, the other physical channel is ultimately used, namely PUCCH3. Therefore, the timeline end time is defined as the start position of PUCCH3 (the final result (The result is different from the timeline end position in the prior art.) In Fig. 8d, Since the channel is another physical channel, namely PUCCH3, the timeline end time is The final result is the end position of the timeline in the prior art. FIG. 8 shows the case where N1+X and N2+Y have the same end point. However, in practice, the end point may be different. The timeline end time corresponds to the later of the end points of N1+X and N2+Y above. That is, the timeline end time corresponding to this method is the end of N1+X and N2+Y. Not before both points.

[0060] For example, in Fig. 1c, according to the rule, the PUSCH channel is the one that is finally used. In the case of a PUCCH channel, the timeline end time is not the start position of the PUCCH according to the related art. It is defined as the starting position of the PUSCH rather than the starting position of the final transmitted physical channel. The timeline end time was delayed, so the timeline end time was used as the It can resolve many overlaps in the time domain, making it easier to process timelines. This will reduce the burden of time arrangements for

[0061] For example, in q in Figure 1, according to the rule, the one that is finally used is PUCCH1. If it is a channel, the timeline end time is the start position of PUCCH2 according to the related art. It is defined as the start position of PUCCH1, not the start position of the physical channel that is finally transmitted. The start position is used as the timeline end time, and the timeline end time is delayed. This allows more overlaps in the time domain to be resolved, and timeline processing is simplified. This can reduce the burden of time arrangements for management.

[0062] Obviously, the definition of the timeline end time determined by the method according to the present embodiment is different from that of the prior art. It is more accurate than the previous version and helps in arranging the timeline for product realization. , making the timeline more compact and efficient.

[0063] An example is provided below. For one UE, in one slot, both are PUCCH or PUSCH. Multiple physical channels, which may be a combination of PUCCH and PUSCH, are allocated to the Burlapped (completely overlapping or partially overlapping in the time domain) In this case, the UE processes data to be transmitted on multiple physical channels. Only when the timeline meets the requirements can the information in the multiple physical channels be finally The PUCCH or PUSCH is determined (actually used) and transmitted (i.e. That is, once the processing timeline requirement is met, the UE can perform time domain overhaul of multiple physical channels. otherwise, the UE will be expected to handle multiple physical channels. does not handle overlap in the time domain and considers it an incorrect setting.

[0064] Specifically, the processing timeline must meet the following requirements:

[0065] For the UE, the first synchronization of one PUCCH or PUSCH finally determined is The number of physical channels is m, where m is a positive integer greater than 1. The preparation times T1, T2, ..., T required to prepare data to be transmitted corresponding to the physical channels n (where Tn value corresponds to the nth physical channel among the m physical channels. , n = 1, 2, ..., m. The meaning of Tn below is the same as that here, and the explanation is The T value may be expressed in terms of the number of symbols. do.

[0066] The time lengths T1, T2, ..., Tn correspond to each of the multiple physical channels. The corresponding channel or signal (for example, in FIG. 8a, the signal corresponding to the PUSCH is shown in FIG. N2+Y previous DCI (carried in PDCCH) of A / N PUCCH The channel corresponding to is the PDSCH before N1+X in the figure, and then, PUSCH The corresponding preparation time length is N2+Y, and the preparation time length corresponding to A / N PUCCH is N It is 1+X.

[0067] In FIG. 8c, the signal corresponding to PUCCH1 is the DCI before N2+Y shown. , the channel corresponding to PUCCH2 is PDSCH N1+X in the figure, and PUCCH The preparation time length corresponding to PUCCH1 is N2+Y, and the preparation time length corresponding to PUCCH2 is N For example, when semi-statically (semi-persistently) configured, the above corresponding channel A channel or signal may not exist, but it is assumed that a corresponding channel or signal exists before. The last sequence of the time lengths T1, T2, ..., Tn is given. It is measured from the symbol.

[0068] The PUCCH or PUSCH channel that is finally determined is the It may be one of the above physical channels, or one physical channel other than the above physical channels. If the latter, you may refer to the following optional requirement (if you support this requirement, (It is not necessary to port the first physical channel among the above physical channels.) The symbols are the data to be transmitted corresponding to each physical channel of the plurality of physical channels. Not before any of the preparation times T1, T2, ..., Tn required for preparation, and finally The first symbol of the determined PUCCH or PUSCH channel is The preparation times T1 and T2 required to prepare data to be transmitted corresponding to each physical channel of the channel , . . . , Tn, and the time lengths T1, T2, . . . , Tn are not before any of the above multiple The physical channels are counted from the last symbol of the channel or signal corresponding to each physical channel. can be.

[0069] Before the first symbol of one PUCCH or PUSCH finally determined, Each of the plurality of physical channels for transmitting data is a corresponding transmission channel. There is enough time to prepare the data to be sent, i.e., one of the above final decisions Generate the final transmission target data before the first symbol of PUCCH or PUSCH Only by having enough time to prepare and send the final The data to be transmitted is derived from the information in the above physical channels and is transmitted according to a set format. The final data to be transmitted is determined by the protocol TS. Please refer to the methodology set out in 38.213. The end time is the first signal of one PUCCH or PUSCH that is finally determined here. It's Bol.

[0070] The final PUCCH or PUSCH to be determined is the currently overlapping PUCCH or PUSCH. It may be one of a plurality of physical channels, or another physical channel, e.g., another P UCCH / PUSCH (other physical channels may also be configured in the UE) , may be from a PUCCH set, or a SR PUCCH, or a CSI PUCCH. stomach).

[0071] Hereinafter, another example will be described. Two typical overlaps in the time domain In the first type, multiple PUCCH channels overlap, and ultimately determining a PUCCH for carrying UCI information in the plurality of PUCCH channels; The remaining PUCCH channels are discarded. In the second type, PUCCH channels (one or more) and PUSCH channel (generally, one PUSCH, if there are multiple PUSCHs These multiple PUSCH channels are in a time-division relationship. In this case, one PUSCH channel is finally determined and overlapped. The UCI information in the PUCCH channel is carried by the It is still transmitted on PUSCH. This is a very typical scenario for two do.

[0072] In the first scene, P UCCH1 and PUCCH2, which carries one CSI, overlap in the time domain. If the UE decides to use PUCCH3 in this case, The first symbol of PUCCH3 indicates that PUCCH1 is preparing HARQ-ACK information. The time required for the UE to decode the corresponding PDSCH and then decode the HAR Since T1 needs to generate HARQ-ACK after checking the Q-ACK information, Includes the time length for processing the PDSCH.

[0073] In some cases, if the UE knows the number of bits of HARQ-ACK, it can set the specific bit value. (T1 is the number of symbols, and P DSCH) and PUCCH2 carries CSI information. It is not before the time T2 required for preparation (preparation of CSI information requires a certain amount of time). , before the corresponding channel may be triggered, and CSI and HARQ_ACK It may require joint coding, in which case HARQ- ACK bit information is required, and thus the CSI preparation time is longer. We expect that the following conditions will be met:

[0074] T2 is the number of symbols, and the maximum number of channels for which PUCCH2 carries CSI and is triggered. The time is measured from the next symbol (here PUCCH2 is dynamically triggered). (The channel can be triggered whether it is configured automatically or semi-statically.)

[0075] That is, the start symbol of PUCCH3 cannot be earlier than T1 and T2. Depending on the situation, T1 and T2 correspond to different lengths of time, and PUCCH1 and PUCCH2 The type of UCI transmitted in Obviously, T1 and T2 are related to the above three factors. For example, the data between PUCCH1 and PUCCH2 is There may be a certain priority in the coding, e.g. In general, only when two pieces of data can be generated can joint coding begin. In the case of puncture transmission, the data to be punctured is generally When preparing the data, other data must be generated at the same time, so the time taken For rate matching, in general, when preparing data to be punctured, When transmitting a message, it is necessary to know at least the number of bits of other data (even if the bit value is not known). This takes a moderate amount of time.

[0076] The following are some specific examples of application. Different physical channels are used depending on the type of data being transmitted. The preparation time required varies depending on the

[0077] One UE may have multiple overlapping (time-domain or frequency-domain) (These PUCCHs are non-overlapping) If the signal is transmitted in one slot, 9.2.5.1 and 9.2.5 of TS 38.213 are applicable. As shown in subclause .2, the UE can recognize different UCI types (e.g., HARQ-ACK, and and / or SR, and / or periodic / semi-persistent CSI) into one PUCCH. In this case, the UE does not transmit overlapping PUSCH in the slot, and transmits all PUSCHs. All corresponding UCI types are multiplexed into one PUCCH.

[0078] If one of the types of UCI includes HARQ-ACK information, the UE shall The first symbol of PUCCH that is finally decided to be used is numbered N1+X (The number is not before the corresponding PDSCH symbol or SPS P DSCH release) and numbered N2+Y. (The number is from the last symbol of the corresponding PDCCH symbol to the where N1 is the number of symbols and the UE PDSCH processing time The PDSCH processing capability of the UE is denoted as 1, N2 is the number of symbols, and This corresponds to the USCH preparation time length and is denoted as PUSCH processing capability 1. Burlapped PDCCH and PUSCH (these channels are non-overlapping) in one slot If the UE wants to transmit in the same frame, it must transmit all the supported UCI types (HARQ-ACK , and / or SR, and / or periodic / semi-persistent CSI) onto one PUSCH. do.

[0079] The UE then transmits the PUCCH or PUS that it has finally decided to use in this slot. The first symbol of CH is not before a symbol whose number is N1+X (the number is The corresponding PDSCH symbol or SPS PDSCH release symbol (The number is calculated by counting N1+X symbols from the last symbol in the sequence.) , not before the symbol whose number is N2+Y (the number is the corresponding PDCCH symbol (The number is calculated by counting N2+Y symbols from the last symbol in the file.) N1, N2, X, and Y each indicate the number of OFDM symbols. N1 and N2 are The values ​​in TS 38.214 are used, and the values ​​of X and Y are given according to the UE processing capabilities. can be done.

[0080] Clauses 9.2.5.1 and 9.2.5.2 of TS 38.213 assume the following: is doing.

[0081] For one UE, SR transmission and HARQ-ACK transmission are over in one slot. or overlapping the SR transmission with one periodic / semi-persistent CSI transmission. r; Satisfying the situation of multiplexing corresponding UCI types in a single PUCCH; The UE shall not use any overlapping P It does not transmit USCH either.

[0082] Example 2 When defining the timeline end time, the larger physical channel range should be included. For example, the conventional technology currently uses physical channels where overlap occurs in the time domain. simply select the earliest physical channel start position as the timeline end time. In this embodiment, to transmit information in physical channels that currently overlap in the time domain, The start position of the earliest physical channel, including other physical channels that may be used, Suggest a time to select as the timeline end time.

[0083] For example, in Fig. 1m and n (for other figures, the principle is the same), the related method The end of the timeline is now the point where two physics teams overlap in the time domain. The start of the earliest physical channel in time is considered to be the start of the physical channel. Currently, two physical channels with overlap in the time domain are used in the end. If another physical channel is used, the start position of the other physical channel is the earliest one. This may cause some problems as it is different from the opening position of the channel (see previous analysis). see).

[0084] Therefore, the present application relates to a method for transmitting a plurality of physical channels over a single UE in the time domain. If wrapping, the timeline end time is set to the PUCCH set of the UE (one UE One or more PUCCH sets can be set for each PUCCH set. All PUCCHs that may be used and / or all PUCCH resources of the UE Finally, all PUCCH resources that may be used (currently overlapped in the time domain) The earliest PUCCH among all PUCCHs, including the PUCCH to be We propose to define it as the starting position.

[0085] For example, in Fig. 1, m, PUCCH1 is format 3 and carries AN information (U E may be multiplexed together), and PUCCH2 is If SR information is carried by the 1st base station, PUCCH2 is discarded and SR is Convert it into X-bit (related to the number of SR) information and connect it to the AN bit of PUCCH1, Then, another PUCCH resource of format 3 is used for transmission.

[0086] Specifically, which format 3 resource to use, first, X and AN The PUCCH set is determined according to the total number of bits of The total number of bits transmitted by the H resource is different, each corresponding to a range of bit numbers, In general, there is still a high probability that the PUCCH set will not be changed. Since the range of the total number of bits carried in the set is large and the newly added bits are small, (Probability that the total bit range carried in the next PUCCH set will not be exceeded) From the PUCCH set to be transmitted, the PUCCH resource specified by the base station is used. Perform transmission.

[0087] Using the above definition of the timeline end time, the most recent PUCCH will be Because it is possible that the start position of an earlier PUCCH may be used as the timeline end time , the timeline end time is later than the start position of the PUCCH resource that is finally transmitted. It won't happen.

[0088] For example, in Fig. 1, PUCCH1 carries CSI in format 3, and PUCCH2 carries CSI in format 4. If CCH2 carries CSI in format 2, the CSI and PUCC The CSI bits of H1 and H2 are concatenated and transmitted using one PUCCH resource. In terms of which Format 3 resource to use, the following is a summary of the prior art: According to the PUCCH selection rule, one PUCCH is selected from the multiple allocated PUCCH resources. In this embodiment, the timeline end time is set to To define it as the earliest PUCCH start position among all PUCCH resources, The timeline end time must not be later than the start position of the final PUCCH resource to be transmitted. do not have.

[0089] For example, in Figure 1, n, PUCCH1 carries CSI in format 3, and PUCCH2 carries CSI in format 4. If CCH2 is format 1 and carries AN, discard PUCCH2 according to the rules. Then, the AN information is concatenated with the CSI bits of PUCCH1, and then one P Transmission is performed using UCCH resources. Specifically, which format 3 resources are used? First, the PUCCH set is determined according to the total number of AN and CSI bits. (The total number of bits transmitted by the PUCCH resources in each PUCCH set is different, and Each of them corresponds to a range of bit numbers, but generally, the PUCCH set is still The probability of not changing the total number of bits carried in each PUCCH set is large. Since the number of newly added bits is small, the total bit range originally carried in the PUCCH set is Then, the PUCCH set is selected from the corresponding PUCCH set. Transmission is carried out using CCH.

[0090] Using the above definition of the timeline end time, the timeline end time is the final transmission The start position of the PUCCH resource to be transmitted must not be later than the start position of the PUCCH resource to be transmitted.

[0091] Example 3 One PUCCH channel and multiple time-division PUCCH channels are overlaid in the time domain. FIG. 9 shows some possible schematic diagrams, and FIG. 9 shows one PU of this embodiment. There are several possible cases where the CCH and two time-division PUCCHs overlap in the time domain. 9 is a schematic diagram of the case, and the present embodiment is not limited to the schematic diagram of FIG.

[0092] For one UE, one PUCCH channel and multiple time-division PUCCH channels If the two channels overlap in the time domain, how can the UE transmit the uplink control channel? How to convey data in each uplink control channel? In this paper, several solutions are proposed for two physical channels that overlap in the time domain. It has stages, and can refer to TS 38.213, but there are more than two channels at the same time. In particular, when there is overlap in the area of ​​one physical channel and two time-division physical channels, simultaneously overlap in the time domain.

[0093] Method 1 For one UE, one PUCCH4 (the latter number is for distinction) and Two time division PUCCHs (e.g. PUCCH5 and PUCCH6) are assigned to one slot. If the PUCCHs overlap in the time domain, the UE will always use one of the two time-division PUCCHs. In this way, the PUCCH is overloaded in the time domain. Two PUCCHs remain to wrap around, i.e. the selected PUCCH and another PUCCH (e.g. , PUCCH4) are considered as two physical channels that overlap in the time domain. The specific method for selecting one of the two time division PUCCHs is as follows: It is.

[0094] This is a method for selecting the nth item (in the time domain direction, n may be 1).

[0095] Alternatively, the PUCCH with the largest number of symbols is selected, and if the number of symbols is the same, the single This is a method of selecting the nth PUCCH with the largest number of bits (n can be 1). do.

[0096] Alternatively, the PUCCH with the smallest number of symbols is selected, and if the number of symbols is the same, the A method for selecting the nth PUCCH with the smallest number of symbols (n can be 1) It is.

[0097] Alternatively, the base station may instruct the UE which PUCCH to select by signaling. , may be indicated by the downlink control information DCI or may be indicated by the control channel unit of the DCI. For example, the first CCE of the DCI or Depending on whether the index of the last CCE is even or odd, the corresponding PUCCH is selected. For example, if the CCE index is even, select the first PUCCH accordingly. , if the CCE index is odd, select the second PUCCH correspondingly.

[0098] Alternatively, a PUCCH (as in the first and second embodiments or the prior art) that satisfies the processing timeline requirements may be used. Refer to the definition of the timeline end time in the (if the deadline is longer than the deadline, it is considered to meet the processing timeline requirement) and If all CCHs meet the processing timeline requirements, This is a method to select the nth one of the items (n can be 1). The earlier the CCH time, the harder it is to meet the processing timeline requirements. The UE knows the processing capability of the PUCCH, the locations of the three PUCCHs and the Knowing the information stored in the UE, the base station can adjust the UE’s timeline requirements according to its processing capabilities. I know the timeline and where the timeline ends. Therefore, the PUCC We know whether H satisfies the processing timeline requirements.

[0099] Alternatively, the base station and the UE may leave two time-division PUCCHs and discard another PUCCH. (i.e., keep PUCCH5 and PUCCH6, and discard PUCCH4) The uplink control information UCI in PUCCH4 is and transport the patient.

[0100] One PUCCH and two time-division PUCCHs are time-domain synchronous PUCCHs in one slot. A typical case of bursting is, for example, the periodic channel state information (CSI) or schedule. One PUCCH, configured periodically or semi-statically, carrying a ring request SR, and For example, two dynamic time-division PUCCHs carrying AN information or non-periodic CSI and The difference is that they overlap in area.

[0101] To address the above problem, Method 1 further provides the following processing mechanism.

[0102] Mechanism 1: For one UE, one PUCCH4 (the latter number is for distinction) and Two time division PUCCHs (e.g. PUCCH5 and PUCCH6) are assigned to one slot. If the two Ps overlap in the time domain, the base station and the UE will always use the two Ps with the earlier start positions. UCCH (for example, from the three PUCCHs in Figure 9, always select the starting positions of two PUCCHs) (where the PUCCH position is before another PUCCH) and use A PUCCH is obtained, and the PUCCH to be used and the next PUCCH are overlapped in the time domain. This processing mechanism is It is scalable, for example, the base station and the UE always process the n previous PUCCHs, Obtain the processing result, process the processing result together with the (n+1)th PUCCH, and so on. This allows more PUCCH overlap to be handled. Cut.

[0103] Mechanism 2: For one UE, one PUCCH4 (the latter number is for distinction) and Two time-division PUCCHs (e.g., PUCCH5 and PUCCH6) are transmitted in one slot. If they overlap in the time domain, the UE will always use two time-division PUCCHs and Discard the PUCCH (i.e., the PUCCH at the position of PUCCH4) (as described above for another PUCCH The UCI information in the CCH is carried in the nth time division PUCCH, where n can be 1. Alternatively, the UCI information in the separate PUCCH is also discarded.

[0104] Mechanism 3: Mechanism 1 allows multiple uplink physical channels of a UE to overlap. The present invention can be extended to solve the above problem, where multiple uplink physical channels are Mechanism 3 may consist of multiple uplinks for a UE. When the link physical channels overlap, the base station and the UE first The first and second (the earlier one is the first) uplink physical channels The overlap in the time domain between the uplink physical channels is handled to provide a single uplink and obtaining an uplink physical channel, and combining the obtained uplink physical channel with the plurality of uplink physical channels. The third uplink physical channel is used together with the third uplink physical channel to provide a link between the two channels. Treat it as an overlap in the time domain (if it does not overlap in the time domain, , stop mechanism 3 this time and restart mechanism 3 from the remaining channels), new A new uplink physical channel is obtained, and a fourth uplink physical channel is obtained. Both are treated as overlaps in the time domain between the two channels, and thus The plurality of uplink physical channels are processed.

[0105] During the process, if the start positions of the channels are aligned, e.g. If the start symbols of two or more uplink physical channels are the same, Among the link physical channels, the one with the smaller starting frequency domain index or the Select the one with the larger region index, or the larger number of symbols, or the smaller number of symbols. and process it.

[0106] As an example of mechanism 3, for example, if there are four uplink physical channels, 10 shows the mechanism 3 of the embodiment of the present disclosure. FIG. 10 is a schematic diagram of the time domain overlap of uplink physical channels. Then, according to mechanism 3, the UE first processes PUSCH_A and PUCCH_A. Alternatively, it may be processed in a manner according to related art (the processing manner in the related art is not yet considered). (Although it may be possible that TS38.213 will eventually provide a processing mechanism), The result is that UCI in PUCCH_A is transmitted on PUSCH_A and UCI in PUCCH_B is transmitted on PUSCH_C. A is discarded.

[0107] In this way, by further processing PUSCH_A and PUCCH_D, the result obtained is The UCI in PUCCH_D is also transmitted in PUSCH_A, and PUCCH_D is discarded. In this way, PUSCH_A and PUCCH_C are further processed to obtain The result is that UCI in PUCCH_C is also transmitted in PUSCH_A, In this way, PUSCH_A and PUCCH_B are further However, since PUSCH_A and PUCCH_B do not overlap, the processing is Not performed.

[0108] In this case, PUSCH_A, PUCCH_B, and PUSCH_B remain, and the remaining two The latter two channels still overlap in the time domain, In this case, the processing result is that the UCI in PUCCH_B is transmitted in PUSCH_B. Finally, PUSCH_A (PUSCH_B) is sent and PUCCH_B is discarded. In addition to the data in _A, UCI in PUCCH_A, PUCCH_D and PUCCH_C PUSCH_B (also carries the data in PUSCH_B and the UUCCH_B) In Fig. 10b, according to mechanism 3, the UE First, PUCCH_A and PUCCH_D are processed. Even if they are processed according to the related art, Well (processing methods in related technologies may still be under consideration, but TS38.21 3 finally gives the processing mechanism), the result obtained is that PUCCH_A is left, Assume that PUCCH_D is to be discarded.

[0109] In this way, by further processing PUCCH_A and PUSCH_A, the result obtained is P UCCH_A is discarded and PUSCH_A is left. After processing USCH_A and PUCCH_C, the result is that PUCCH_C is discarded. In this way, PUSCH_A and PUSCH_B are further separated. However, since PUSCH_A and PUSCH_B do not overlap, Therefore, no processing will be performed.

[0110] In this case, PUSCH_A, PUCCH_B and PUSCH_B remain, and the remaining two The latter two channels still overlap in the time domain, In this case, the processing result is that the UCI in PUCCH_B is transmitted in PUSCH_B. Finally, PUSCH_A (PUSCH_B) is sent and PUCCH_B is discarded. In addition to the data in _A, UCI in PUCCH_A, PUCCH_D and PUCCH_C PUSCH_B (also carries the data in PUSCH_B and the UUCCH_B) (It also transports CI) remains.

[0111] As an effective complement to Mechanism 3, the main thing to note is that When processing two overlapping uplink physical channels, one uplink A physical channel is obtained, and the obtained uplink physical channel is It may be from two overlapping uplink physical channels, but Possible signals that are not from two uplink physical channels that overlap in the time domain For example, this channel may be the PUCCH set configured for the UE or the UE The obtained uplink physical The channel is from two uplink physical channels that overlap in the time domain. If not, the obtained uplink physical channel and the plurality of uplink objects are The unprocessed channels of the physical channels are processed using the mechanism 3 above. do.

[0112] In method 1, if you need to process two channels that overlap in the time domain, An existing processing mechanism can be used, which is Depending on the type of information carried in the message, there are corresponding processing mechanisms, which are described in TS 38.2. See reference 13.

[0113] Method 2 Method 1 is a simple method and is easy to implement. Method 2 is a method that overlaps in the time domain. The processing is done precisely according to the type of UCI carried in the channel. Please refer to Tables 1 to 4.

[0114] Here, you can check the end time of the timeline in Examples 1 and 2. For example, in the case of the overlap illustrated in FIG. 9, the overlap is always in the time domain. All channels that meet the above timeline end times will be recognized. Currently, there are five PUCCH formats in the NR system: F0, F1, F2, and F3. There are differences in the definitions of various PUCCHs and the data transmission methods. Since the content of the transmitted UCI may vary depending on the The processing method for many cases is described. One AN PUCCH and two time division SR The process for PUCCH overlap in the time domain is shown in Table 1. One AN PUCCH and two time-division SR PUCCHs overlap in the time domain. This is a process for dealing with this.
