[0027] The method, apparatus, device and readable storage medium for multiplexing UCI provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings and some embodiments and application scenarios.

[0028] Referring to Figure 2 The embodiments of the present application provide a method for multiplexing UCI, which is executed by a terminal and includes the following step 201.

[0029] Step 201: multiplexing the first UCI carried by the first PUCCH to the first PUSCH transmission when the first PUCCH and the first PUSCH at least partially overlap in time domain; the first PUSCH is a PUSCH occupying multiple time units, wherein the time unit can be a slot, a sub-slot, a symbol or a subframe, etc.

[0030] The types of the first UCI include: hybrid automatic repeat request acknowledgement (HARQ-ACK), channel state information (CSI) reporting, scheduling request (SR), and configured grant uplink control information (CG-UCI). The processing of the CG-UCI multiplexed in the configured grant physical uplink shared channel (CG-PUSCH) is similar to that of the HARQ-ACK.

[0031] The CSI can be triggered by the downlink control information (DCI) / media access control control element (MAC CE) in the PUSCH transmission.

[0032] It can be understood that if the first UCI on the first PUCCH is multiplexed to the first PUSCH transmission, the first UCI and the data part of the first PUSCH transmission are separately encoded and mapped for transmission. When the first UCI is multiplexed to the first PUSCH transmission, the network can configure a beta-offset value for the first PUSCH to determine the number of symbols or resource elements (REs) occupied by the first UCI in the first PUCCH. The larger the beta-offset value, the more resources occupied by the first UCI in the multiplexed first PUSCH.

[0033] At the same time, the network can configure an alpha value to determine the number of symbols or REs occupied by the first UCI multiplexed to the first PUSCH, i.e., the resources occupied by the first UCI after being multiplexed to the first PUSCH cannot exceed the upper limit of the number of symbols or REs determined by the alpha value.

[0034] For example, multiplexing multiple first UCI carried by the first PUCCH onto the first PUSCH for transmission, or multiplexing the first UCI carried by the first PUCCH onto the first PUSCH for transmission multiple times, which can further reduce the PUCCH transmission delay.

[0035] In a New Radio (NR) network, cross-slot PUSCH transmission can be supported, that is, one PUSCH can be transmitted in multiple slots. One implementation is to determine the transport block size (TB size) of the PUSCH according to the total number of symbols or resource elements (REs) of the multiple slots.

[0036] In the embodiments of the present application, the first PUSCH can be a time-continuous PUSCH, or the first PUSCH can also be a time-non-continuous PUSCH.

[0037] In the embodiments of the present application, the method can further include:

[0038] Determining the number of resources occupied by the first UCI in the first PUSCH according to the number of at least part of the resources of the first PUSCH.

[0039] The number of at least part of the resources of the first PUSCH is the number of resources available for transmitting multiplexed UCI on the first PUSCH.

[0040] It can be understood that the number of resources herein can be the number of symbols, the number of resource elements, the number of sub-slots, the number of slots, the number of radio frames, etc.

[0041] Further, in the embodiments of the present application, the determining the number of resources occupied by the first UCI in the first PUSCH according to the number of at least part of the resources of the first PUSCH can include:

[0042] Determining the number of resources occupied by the first UCI in the first PUSCH according to the configuration parameter and the number of at least part of the resources of the first PUSCH;

[0043] The configuration parameter can include one or more of the following:

[0044] (1) a first parameter, the first parameter being used to determine the number of resources occupied by the first UCI;

[0045] (2) a second parameter used to determine a number of resources in the first PUSCH available for the first UCI multiplexing transmission, which can be understood as a maximum number of resources in the first PUSCH that can be used for the first UCI multiplexing.

[0046] For example, the first parameter is a beta-offset value, and the second parameter is a scaled or scaled-up alpha value, such as an alpha value configured according to a preset ratio, which is not limited in the embodiments of the present application.

[0047] For example, the first parameter determines a number of resources occupied by the first UCI as A, and the second parameter determines a number of resources in the first PUSCH available for the first UCI multiplexing transmission as B. If A is greater than B, the number of resources occupied by the first UCI in the first PUSCH can be determined as B. If A is less than B, the number of resources occupied by the first UCI in the first PUSCH can be determined as A.

[0048] In the embodiments of the present application, the number of at least part of resources of the first PUSCH is determined according to one or more of the following:

[0049] (1) a number of symbols of the first PUSCH;

[0050] (2) a number of resources of the first PUSCH except Demodulation Reference Signal (DMRS);

[0051] For example, the number of symbols of the first PUSCH is M, and the number of symbols occupied by DMRS is N. The number of at least part of resources of the first PUSCH is M-N.

[0052] (3) a number of resources configured by a network;

[0053] Optionally, the number of resources configured by the network is less than or equal to the number of symbols of the first PUSCH, or the number of resources configured by the network is less than or equal to the number of resources of the first PUSCH except DMRS.

[0054] (4) a predefined number of resources;

[0055] For example, a number of resources nominally or actually occupied by PUSCH transmission in 1 slot, for example, the predefined number of resources is 14 symbols, of course, not limited thereto.

[0056] (5) a number of resources occupied by UCI already multiplexed for transmission on the first PUSCH;

[0057] That is, before multiplexing the first UCI on the first PUSCH, other UCI is multiplexed on the first PUSCH, at this time, the number of resources occupied by the first UCI is determined according to the number of resources occupied by the other UCI

[0058] (6) The type of the first UCI.

[0059] For example, the type can be a hybrid automatic repeat request acknowledgement (HARQ-ACK), a scheduling request (SR), a channel state information (CSI) part 1, and a CSI part 2.

[0060] Exemplarily, taking the first UCI carried by the first PUCCH as a CSI (such as an aperiodic CSI (A-CSI)) as an example, the CSI is transmitted on the first PUSCH in multiple slots, and then the CSI is transmitted on:

[0061] (1) The first slot on the first PUSCH; optionally, the slot is a complete slot;

[0062] (2) The first slot containing a DMRS on the first PUSCH;

[0063] (3) The first slot on the first PUSCH, the length of the first symbol (except the DMRS) is greater than or equal to L, and L is a preset value.

[0064] In the embodiments of the present application, in order to determine the number of resources occupied by the first UCI carried by the first PUCCH multiplexed to the first PUSCH, the network will configure a first parameter (β) and a second parameter (α), and determine the number of resources occupied by the first UCI according to the number of at least part of the resources of the first PUSCH.

[0065] The number of at least part of the resources of the first PUSCH can be configured for the first PUSCH transmitted in multiple slots, and the first parameter (β) and the second parameter (α) can be different from the parameters configured for the PUSCH transmitted in one slot.

[0066] Alternatively, the number of resources occupied by the first UCI multiplexing is determined according to a reference resource number. The reference resource number can be less than or equal to the number of symbols (or the number of symbols except the DMRS) of the first PUSCH in multiple slots, or a predefined resource number of 1 slot, for example, 14 symbols, to determine the number of resources occupied by the first UCI multiplexing.

[0067] For example, the first PUSCH needs at least part of the resource number of HARQ-Ack multiplexing:

[0068]

[0069] The For calculating the reference symbol number of at least part of the resource number Q′ UCI of the first PUSCH, it can be:

[0070] The number of symbols of the first PUSCH excluding DMRS;

[0071] Or, the preset symbol number, for example, the symbol number corresponding to M slots greater than or equal to 1, M is a positive integer;

[0072] Or, the number of consecutive symbols of the first PUSCH overlapping the first PUCCH.

[0073] Wherein, C UL-SCH is the number of code blocks of the uplink shared channel (UL-SCH) of the PUSCH transmission;

[0074] K r is the rth code block size of the UL-SCH of the PUSCH transmission;

[0075] The number of resource elements available for transmitting UCI in the orthogonal frequency division multiplexing (OFDM) symbol l;

[0076] O UCI is the number of bits of the UCI;

[0077] L UCI is the number of cyclic redundancy check (CRC) bits of the UCI.

[0078] In the embodiments of the present application, before step 201, the method further comprises:

[0079] According to the number and / or times of the UCI multiplexed and transmitted on the first PUSCH, one or more of the following is determined:

[0080] (1) whether to multiplex and transmit the first UCI on the first PUSCH;

[0081] (2) the number of resources occupied by the first UCI on the first PUCCH;

[0082] (3) the multiplexing manner of the first UCI on the first PUCCH (such as rate matching or puncturing).

[0083] In the embodiments of the present application, after the UCI multiplexing on the first PUSCH, the UCI multiplexing can continue in the subsequent transmission (such as the second and subsequent UCI multiplexing), further reducing the transmission delay of the PUCCH.

[0084] In the embodiments of the present application, before step 201, the method further comprises:

[0085] According to whether the first PUCCH is repeatedly transmitted, the number of multiplexing transmissions of the first UCI on the first PUSCH is determined.

[0086] In the embodiments of the present application, if the number of multiplexing transmissions of the UCI on the first PUSCH is x times, or if the number of multiplexing transmissions of the UCI on the first PUSCH is y, after transmitting the first PUSCH, if the second PUCCH at least partially overlaps in time domain with the first PUSCH, the method further comprises one or more of the following:

[0087] (1) not transmitting the second PUCCH, i.e. no longer multiplexing the UCI carried by the second PUCCH on the first PUSCH;

[0088] (2) according to the priority of the second PUCCH, determining whether to multiplex the second UCI carried by the second PUCCH on the first PUSCH for transmission;

[0089] (3) according to the type of the second UCI carried by the second PUCCH, determining whether the second UCI is multiplexed and transmitted on the first PUSCH;

[0090] For example, multiplexing certain types of UCI, such as HARQ-ACK, SR, and CSI part 1, and not multiplexing other types of UCI, such as CSI part 2.

[0091] (4) according to the resources occupied by the multiplexed UCI on the first PUSCH, determining whether the second UCI carried by the second PUCCH is multiplexed and transmitted on the first PUSCH;

[0092] For example, if the resources occupied by the multiplexed first UCI are greater than a threshold, the second UCI is not multiplexed and transmitted on the first PUSCH.

[0093] Wherein, the x is less than or equal to the maximum number X of multiplexing UCI on the first PUSCH, and the y is less than or equal to the maximum number Y of multiplexing UCI on the first PUSCH.

[0094] In the embodiments of the present application, if it is determined that the second UCI is multiplexed and transmitted on the first PUSCH, the method further comprises:

[0095] Determining the resource occupied by the second UCI multiplexed and transmitted on the first PUSCH;

[0096] Wherein, the resource occupied by the second UCI does not include the resource occupied by the multiplexed UCI on the first PUSCH.

[0097] In the embodiments of the present application, the determination of multiplexing the second UCI on the first PUSCH for transmission comprises one of the following:

[0098] (1) According to one or more of the first parameter, the second parameter, the number x of multiplexing the first UCI on the first PUSCH, and the number y of multiplexing the first UCI on the first PUSCH, determine the number of resources occupied by the second UCI multiplexed and transmitted on the first PUSCH;

[0099] Wherein, the first parameter is used to determine the number of resources occupied by the first UCI; and the second parameter is used to determine the number of resources available for multiplexing transmission of the first UCI in the first PUSCH;

[0100] It can be understood that the same first parameter (β) and second parameter (α) can be used for multiplexing different UCI on the first PUCCH.

[0101] (2) According to the third parameter and the fourth parameter, determine the number of resources occupied by the second UCI multiplexed and transmitted on the first PUSCH;

[0102] Wherein, the third parameter is used to determine the number of resources occupied by the second UCI, that is, the third parameter is β configured for multiplexing the second PUCCH, or the third parameter can be determined based on the first parameter, for example, based on the reduction or enlargement of the first parameter.

[0103] The fourth parameter is used to determine the number of resources available for multiplexing transmission of the second UCI on the first PUSCH, that is, the fourth parameter is the value of α configured for multiplexing the second PUCCH, or the fourth parameter can be determined based on the second parameter, for example, based on the reduction or enlargement of the second parameter.

[0104] In the embodiments of the present application, if it is determined that the second UCI is multiplexed and transmitted on the first PUSCH, the method further comprises:

[0105] determining a multiplexing manner of multiplexing transmission of the second UCI on the first PUSCH;

[0106] The multiplexing manner includes one or more of the following:

[0107] (1) rate matching or puncturing the second UCI on the first PUSCH;

[0108] (2) the resource occupied by the second UCI on the first PUSCH does not include the resource occupied by the multiplexed UCI on the first PUSCH, that is, when the second PUCCH is multiplexed onto the first PUSCH, the resource occupied by the multiplexed UCI is avoided.

[0109] Referring to Figure 3 , because the time domain resource occupied by the PUSCH transmitted in multiple slots is relatively large and the continuous transmission duration is relatively long, which can be continuous transmission or non-continuous transmission, there can be a case where multiple / many times of UCI are multiplexed onto one PUSCH, and when multiple or many times of UCI are multiplexed, a new multiplexing behavior needs to be defined.

[0110] Referring to Figure 4 , the PUSCH is transmitted in two non-continuous uplink slots, and one UCI is multiplexed on the first slot, which can be HARQ-ACK feedback corresponding to a PDSCH (or other UCI types such as SR, CSI, etc., or transmitted together with these UCIs).

[0111] The UCI in the figure is also HARQ-ACK, corresponding to the PDSCH transmitted between the two slots, or the UCI corresponds to CSI transmission.

[0112] The existing PUSCH transmission of less than or equal to 1 slot supports multiplexing of 1 time of UCI, and after the introduction of the first PUSCH of multiple slots, it is further necessary to determine whether and how to support multiplexing of many times of UCI.

[0113] Based on the description of the embodiments of the present application, it can be determined that in the case where 1 time of UCI has been multiplexed, if the second PUCCH and the first PUSCH overlap in the time domain, the first PUSCH of multiple slots does not multiplex the second time of UCI.

[0114] Or, according to the priority of the UCI carried by the second PUCCH, for example, multiplexing transmission of HARQ-ACK corresponding to high priority, otherwise not multiplexing transmission.

[0115] Or, multiplexing according to the type of second UCI carried by the second PUCCH, only multiplexing certain types of UCI, for example, HARQ-ACK, SR, CSI part 1; not multiplexing for other types of CSI, for example, CSI part 2.

[0116] Or, according to the occupied resources of the multiplexed UCI on the first PUSCH, determine whether to multiplex the second UCI, if the occupied resources of the multiplexed UCI occupy more than a threshold, do not multiplex all or part of the second UCI carried by the second PUCCH.

[0117] If the number of multiplexed UCI exceeds the maximum number Y of UCI that can be multiplexed on the first PUSCH, or the number of multiplexed UCI has exceeded the maximum number X of UCI that can be multiplexed on the first PUSCH, then no longer multiplex UCI.

[0118] Further, if it is determined that multiplexing is needed according to the above rules, the following method can be used to determine the resources for multiplexing transmission.

[0119] For example, using a first parameter (beta-offset), a second parameter (alpha) to determine the resources occupied by the second UCI carried by the second PUCCH, i.e. the above parameters determine the resources available for second UCI multiplexing transmission in the first PUSCH, since the first UCI has been multiplexed, the number of resources occupied by the multiplexed first UCI needs to be subtracted in the process of calculating the resources.

[0120] Optionally, the multiplexing of the second PUCCH on the first PUSCH is not completely overlapped with all UCI in the first PUCCH, i.e. some UCI has been multiplexed before, because the available resources are not enough, it cannot be transmitted, then the multiplexing of the second PUCCH on the first PUSCH is not performed.

[0121] Or, according to the third parameter or the fourth parameter to determine the number of resources that the second UCI carried by the second PUCCH can occupy when multiplexed on the first PUSCH, these parameters can be associated with the configuration of the xth multiplexing or the yth UCI multiplexing, i.e. the network can configure different parameters for different numbers of UCI multiplexing to determine the number of resources occupied by UCI multiplexing transmission.

[0122] Or, define the calculation method of the third parameter or the fourth parameter, for example, the reduction or amplification relative to the first parameter or the second parameter respectively. When determining the number of resources occupied by the second PUCCH multiplexing according to the third parameter and the fourth parameter, the number of resources of the first PUSCH (excluding DMRS) can be used as the basis, or the number of resources of the first PUSCH (excluding DMRS) minus the number of resources occupied by the multiplexed UCI, or the number of symbols overlapping the slot where the first PUSCH is located, or the number of symbols of the continuous transmission of the overlapping first PUSCH.

[0123] Further, after determining the number of resources, the multiplexing manner and the location of the transmission resource can be further determined.

[0124] For example, the multiplexed second UCI is transmitted on the first PUSCH in the form of puncturing or rate matching. The resources occupied by the multiplexed second UCI need to avoid the resources occupied by the multiplexed first UCI, that is, the second UCI multiplexed to the first PUSCH avoids the resources occupied by the multiplexed first UCI. If there is an overlap, the second UCI is postponed to be transmitted on the non-overlapping symbol.

[0125] In the embodiments of the present application, the method further comprises:

[0126] If the first PUSCH is a non-continuous transmission PUSCH, the second UCI carried by the second PUCCH is multiplexed and transmitted on the continuous transmission resource in the first PUSCH.

[0127] In the embodiments of the present application, the method further comprises:

[0128] According to the number of continuous transmission resources in the first PUSCH, the number of resources occupied by the second UCI on the first PUSCH is determined.

[0129] The number of continuous transmission resources in the first PUSCH is the number of symbols of the continuous transmission resources in the first PUSCH, or the number of symbols of the continuous transmission resources in the first PUSCH in a slot.

[0130] In the embodiments of the present application, if the first PUSCH is a non-continuous transmission PUSCH, the method further comprises one of the following:

[0131] (1) Do not transmit the first PUSCH.

[0132] (2) Do not transmit part of the continuous transmission resources in the first PUSCH that overlap or partially overlap in time with the second PUCCH.

[0133] In the embodiments of the present application, the method further comprises:

[0134] If the first PUCCH is a repeated PUCCH, the number of resources of the first PUCCH is determined according to the number of repetitions of the first PUCCH.

[0135] In the embodiments of the present application, the number of resources of the first PUCCH is determined according to the number of repetitions of the first PUCCH, comprising:

[0136] The number of resources of the first PUCCH is determined according to the number of repetitions of the first PUCCH, and a first parameter and / or a second parameter;

[0137] For example, in the case of the first PUCCH being a repeated PUCCH, the number of resources of the first PUCCH is calculated according to the number of repetitions, for example, the first parameter and / or the second parameter is reduced or enlarged according to the number of repetitions, for example, beta-offset is scaled by X times (beta-offset-X-slot=X*beta-offset), and the number of resources of the first PUCCH is determined according to the scaled first parameter.

[0138] In the embodiments of the present application, the method further comprises:

[0139] If the first PUCCH is a repeated PUCCH, when the first condition is met, the step of multiplexing the first UCI carried by the first PUCCH to the first PUSCH for transmission is performed;

[0140] The first condition comprises one or more of the following:

[0141] (1) The number of resources of the first PUCCH is less than or equal to the number of at least part of the resources of the first PUSCH;

[0142] (2) The resources of the first PUCCH transmission are within the duration of the first PUSCH transmission, and optionally, the duration can be the time period from the starting symbol to the ending symbol of the first PUSCH, and the first PUSCH transmission can be a non-continuous transmission.

[0143] In the embodiments of the present application, the method further comprises reporting the terminal capability to the network side device;

[0144] The terminal capability comprises one or more of the following:

[0145] (1) The maximum number of multiplexing UCI on PUSCH supported;

[0146] (2) The maximum number of multiplexing UCI on PUSCH supported;

[0147] (3) Whether to support UCI multiplexing in a rate matching manner.

[0148] Referring to Figure 5 If the first PUCCH is a repeated PUCCH, UCI multiplexing can be performed if the following conditions are met:

[0149] a) The number of slots or symbols P of the repeated first PUCCH transmission is less than or equal to the number of slots or symbols Q of the multi-slot first PUSCH;

[0150] b) The resources of the repeated first PUCCH transmission are within the duration of the PUSCH transmission; the duration can be the time period from the start symbol to the end symbol of the first PUSCH transmission, which can be discontinuous transmission.

[0151] In the embodiments of the present application, if the duration of the first PUSCH transmission is greater than a first threshold, or the number of resources occupied by the first PUSCH is greater than a second threshold, the operation of multiplexing the first UCI carried by the first PUCCH to the first PUSCH transmission is performed.
