Description

[0001] The present application claims the priority of Chinese Patent Application No. 201810910306.9, filed with the National Intellectual Property Office of China on August 10, 2018, entitled "COMMUNICATION METHOD AND COMMUNICATIONS APPARATUS", which is incorporated herein by reference in its entirety.

The field of technology to which the invention belongs

[0002] The present application relates to the field of communication and, in particular, to a communication method and a communication device.

State of the art

[0003] In a 5th generation (5G) mobile communication system, transmission of uplink control information (UCI) is supported over a physical uplink shared channel (PUSCH), and there is scenario, only UCI is sent, and the uplink shared channel (UL-SCH) is not sent, that is, there is a UCI-only scenario.

[0004] In a UCI-only scenario, the sent UCI includes an acknowledgment for a hybrid automatic repeat request-acknowledgement (HARQ-ACK), channel state information part 1 (CSI-part1) and channel state information part 2 (CSI-part2). The requirements of the three types of information for the protection level are lowered in the above order. Therefore, when mapping the above three types of information to resources, the terminal device sequentially maps, based on the quality of the channel estimate, HARQ-ACK, CSI-part1 and CSI-part2 to resource elements (resource element, RE) that can carry data related to to PUSCH.

[0005] In order to obtain the gain from frequency hopping, the PUSCH can be divided into two parts in the time domain, with the two parts being respectively called the first hop (hop 1) and the second hop (hop 2). In order to gain from frequency hopping, the frequency domain resources in hop 1 and hop 2 are typically far apart and at least do not exactly overlap. Accordingly, the HARQ-ACK, CSI-part1 and CSI-part2 are also mapped to hop 1 and hop 2 according to a preset rule. However, the information in the CSI-part1 mapped to the frequency hopping resources is incompletely sent, that is, a part of the CSI-part1 cannot be transmitted. This adversely affects the application of UCI transmission via frequency hopping in a UCI-only scenario.

The essence of the invention

[0006] In the present application, a communication method and a communication device are provided. The mapping rule of CSI-part1 is changed to solve the problem that due to the transmission of UCI by frequency hopping in a UCI-only scenario, the information in CSI-part1 is incompletely sent.

[0007] According to a first aspect, a communication method is provided, which includes: receiving downlink control information, where the downlink control information is used for PUSCH scheduling, PUSCH is used for carrying only UCI, PUSCH includes a first frequency hopping resource, and the second hopping resource, and the start time domain symbol of the first frequency hopping resource is before the start time domain symbol of the second hopping resource; and sending the first UCI on the PUSCH, where the first UCI includes at least one of HARQ-ACK, CSI-part1, and CSI-part2, where the number of coded bits that can be mapped to reserved REs in the first hop resource is the first value, the number of encoded bits that can be mapped to the reserved REs in the second frequency hopping resource is the second value, the first value is not less than the second value, and the reserved REs in the first frequency hopping resource and the reserved REs in the second frequency hopping resource reserved for transmitting a potential HARQ-ACK that is 2 bits or less. The peer device of the device that performs the above method may respectively perform the steps of sending the downlink control information and receiving the first UCI on the PUSCH. It should be noted here that the fact that the PUSCH includes a first hop resource and a second hop resource means that when the frequency hopping identifier field in the DCI uplink grant (UL grant) indicated by the network device allows frequency hopping for the PUSCH, the PUSCH time-frequency domain resource in the first hop, and the PUSCH time-frequency domain resource in the second hop, respectively, are called the first frequency hopping resource and the second frequency hopping resource. In order to distinguish between the first hop resource and the second PUSCH hop resource in the present application, there is a sequential relationship between the start time of the first hop resource and the start time of the second hop resource. In addition, the value of the number of coded bits mapped to a specific number of REs in the PUSCH is equal to the number of REs multiplied by the number of PUSCH transmission levels and then multiplied by the modulation order of the UCI potentially transmitted on the PUSCH.

[0008] The reason that the information in CSI-part1 is not completely sent is because the number of encoded bits that are related to CSI-part1 and which are mapped to the second hop resource is relatively small. In other words, the number of REs on the second hop resource that are used to map the CSI-part1 is relatively small, and therefore the CSI-part1 cannot be fully mapped to the second hop resource. Compared with the prior art, the present application reduces the number of coded bits that can be mapped to the reserved REs in the second hopping resource, thereby increasing the number of REs that are in the second hopping resource that are used to map CSI-part1. This solves the problem that, due to the transmission of UCI by frequency hopping in a UCI-only scenario, the information in CSI-part1 is not completely sent.

Otherwise, the terminal device may determine based on the number (for example,

[0019] According to a second aspect, the present application further provides a communication method, including: receiving downlink control information, where downlink control information is used for PUSCH scheduling, PUSCH is used to carry only UCI, PUSCH includes a first hop resource the frequency and resource of the second frequency hopping, and the start symbol of the time domain of the resource of the first frequency hopping is before the start symbol of the time domain of the resource of the second frequency hopping; and sending the first UCI on the PUSCH, where the first UCI includes at least one of HARQ-ACK, CSI-part1, and CSI-part2. The peer device respectively performs the steps of sending the downlink control information and receiving the first UCI.

of encoded bits that are related to CSI-part1 in the first UCI and that are mapped to the first frequency hopping resource is the smaller of the fourth value and the fifth value, the fourth value is determined based on the number

encoded bits of CSI-part1 in the first UCI, and the fifth value is determined based on the larger value in

and

, or the fifth value is determined based on

, where

is the number of encoded bits that are related to the HARQ-ACK in the first UCI and that are mapped to the first hop resource, and

is the number of coded bits that can be mapped to the reserved REs in the first hop resource.

. Например, пятое значение представляет собой

в уровне техники, и этот параметр устанавливает верхний предел (а именно, первый верхний предел) для ресурса, который занимает CSI-part1 на ресурсе первой скачкообразной перестройки частоты. Кроме того, CSI-part1 не может занимать зарезервированные RE в ресурсе первой скачкообразной перестройки частоты. То есть

также не должно быть больше верхнего предела

(а именно второго верхнего предела). Когда количество информационных битов HARQ-ACK равно 0, 1 или 2,

является количеством кодированных битов, отображаемых на зарезервированные RE, и которое вычисляется на основе количества информационных битов HARQ-ACK, равного 2. Следовательно, если фактическое количество информационных битов HARQ-ACK равно 0 или 1, то

и

. То есть на ресурсе первой скачкообразной перестройки частоты,

. В этом случае первый верхний предел больше второго верхнего предела. В предшествующем уровне техники, если пятое значение определяется только на основе

, то не зарезервированных RE в ресурсе первой скачкообразной перестройки частоты может быть недостаточно для переноса количества

кодированных битов CSI-part1 на ресурсе первой скачкообразной перестройки частоты.[0021] In the prior art, the fifth value is only determined based on

. For example, the fifth value is

in the prior art, and this parameter sets an upper limit (namely, the first upper limit) for the resource that CSI-part1 occupies on the first hop resource. In addition, CSI-part1 cannot occupy reserved REs in the first hop resource. That is

also should not be greater than the upper limit

(namely the second upper limit). When the number of HARQ-ACK information bits is 0, 1, or 2,

is the number of encoded bits, which is calculated based on the actual number of HARQ-ACK information bits, and

is the number of encoded bits mapped to the reserved REs and is calculated based on the number of HARQ-ACK information bits equal to 2. Therefore, if the actual number of HARQ-ACK information bits is 0 or 1, then

and

. That is, on the resource of the first frequency hopping,

. In this case, the first upper limit is greater than the second upper limit. In the prior art, if the fifth value is only determined based on

, then the non-reserved REs in the first hopping resource may not be sufficient to carry the number

encoded CSI-part1 bits on the first hop resource.

and

(where, when the number of HARQ-ACK bits is greater than 2,

equals 0) to ensure that

is calculated using the actual non-reserved REs in the first hop resource as a reference, thereby avoiding the aforementioned problem of incomplete sending of CSI-part1.

[0037] According to the solutions provided in the third aspect, when the number of HARQ-ACK bits is 2, on the first frequency hopping resource, the number of coded HARQ-ACK bits is exactly equal to the number of coded bits mapped to the reserved RE, and on the second frequency hopping resource the number of HARQ-ACK encoded bits is exactly equal to the number of encoded bits mapped to the reserved one.

[0038] According to the fourth aspect, the present application provides a device. The device may implement functions corresponding to the steps in the methods in the first aspect, the second aspect, and/or the third aspect. The functions may be implemented in hardware, or may be implemented by hardware running corresponding software. The hardware or software includes one or more blocks or modules corresponding to the above functions.

[0039] In an exemplary embodiment, the device includes a processor, the processor being configured to support the device in performing appropriate functions in the manner described in the aforementioned first aspect. The device may further include a memory, where the memory is configured to be coupled to the processor and the memory stores program instructions and data that the device needs. Optionally, the device further includes a transceiver, the transceiver being configured to support communications between the device and another network element. The transceiver may be an independent receiver, an independent transmitter, or a transceiver having both transmit and receive functions.

[0040] According to a fifth aspect, the present application provides a computer-readable storage medium. The computer-readable storage medium stores computer program code, and when the computer program code is executed by a processing unit or processor, the methods according to the first aspect, the second aspect, and/or the third aspect are implemented.

[0041] According to the sixth aspect, the present application provides a computer program product. The computer program product includes computer program code, and when the computer program code is executed by a processing unit or processor, the methods according to the first aspect, the second aspect, and/or the third aspect are implemented.

[0042] According to a seventh aspect, a communication method is provided, which includes: sending downlink control information, where the downlink control information is used for PUSCH scheduling, PUSCH is used for carrying only UCI, PUSCH includes a first frequency hopping resource, and the second hopping resource, and the start time domain symbol of the first frequency hopping resource is before the start time domain symbol of the second hopping resource; and receiving the first UCI on the PUSCH, where the first UCI includes at least one of HARQ-ACK, CSI-part1, and CSI-part2, where the number of coded bits that can be mapped to reserved REs in the first hopping resource is the first value, the number of encoded bits that can be mapped to the reserved REs in the second frequency hopping resource is the second value, the first value is not less than the second value, and the reserved REs in the first frequency hopping resource and the reserved REs in the second frequency hopping resource reserved for transmitting a potential HARQ-ACK that is 2 bits or less.

[0043] The reason that the information in CSI-part1 is not completely sent is because the number of encoded bits that are related to CSI-part1 and which are mapped to the second hop resource is relatively small. In other words, the number of REs on the second hop resource that are used to map the CSI-part1 is relatively small, and therefore the CSI-part1 cannot be fully mapped to the second hop resource. Compared with the prior art, the present application reduces the number of coded bits that can be mapped to the reserved REs in the second hopping resource, thereby increasing the number of REs that are in the second hopping resource that are used to map CSI-part1. This solves the problem that, due to the transmission of UCI by frequency hopping in a UCI-only scenario, the information in CSI-part1 is not completely sent.

. For example, the fifth value is

in the prior art, and this parameter sets an upper limit (namely, the first upper limit) for the resource that CSI-part1 occupies on the first hop resource. In addition, CSI-part1 cannot occupy reserved REs in the first hop resource. That is

also should not be greater than the upper limit

encoded CSI-part1 bits on the first hop resource.

Description of Embodiments

[0073] The following describes the technical solutions of the present application with reference to the accompanying drawings.

[0074] In FIG. 1 shows a communication system to which the present application applies. The communication system includes a network device and a terminal device. The network device communicates with the terminal device via a wireless network. When the terminal device sends information, the wireless communication module of the terminal device can receive information bits to be sent to the network device over the channel. For example, the information bits are generated by the processing unit of the terminal device, received from another device, or stored in the storage unit of the terminal device.

[0075] In this application, a terminal device may be referred to as an access terminal, user equipment (user equipment, UE), subscriber device, subscriber station, mobile station, mobile console, remote station, remote terminal, mobile device, user terminal, terminal, wireless device communication, user agent, or user device. The access terminal may be a cellular phone, a portable device having a wireless communication function, a computing device, other data processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, or a user equipment in a 5G communication system.

[0076] The network device may be a base transceiver station (BTS) in a code division multiple access (CDMA) NodeB (Node B, (NB)) in a wideband code division multiple access system (wideband code division multiple access, WCDMA), evolved NodeB (evolved node B, eNB) in a long-term evolution (LTE) system, or gNB (gNB) in a 5G communication system. The above base stations are used only as examples for illustration purposes. Alternatively, the network device may be a relay node, an access point, a vehicle-mounted device, a wearable device, or another type of device.

[0077] The above communication systems to which the present application is applicable are merely examples for description, and the communication system to which the present application is applicable is not limited thereto. For example, the communication system may include a different number of network devices and a different number of terminal devices.

[0078] To facilitate understanding of the technical solutions in this application, the concepts used in this application are first briefly described. The 5G system is used as an example for description.

[0079] In a scenario in which the UE sends the UCI to the gNB on the PUSCH, the UE may not detect the physical uplink control channel (PDCCH). Therefore, a cognitive error occurs regarding the number of HARQ-ACK bits that needs to be sent back, i.e. the number of HARQ-ACK bits actually returned from the UE is less than the number of HARQ-ACK bits that the gNB plans the UE to return. In addition, all UCIs sent from the UE on the PUSCH may be incorrectly received in the gNB. To avoid the impact on CSI-part1 from reducing the number of HARQ-ACKs sent by the UE, reserved REs for HARQ-ACKs are defined in the communication protocol, namely a reserved RE for a scenario in which the UE sends UCI to gNB in PUSCH. The specific definition is as follows:

[0080] (1) When the number of HARQ-ACK information bits is 0, 1, or 2, reserved REs are generated based on the number of HARQ-ACK information bits equal to 2.

[0081] (2) Since CSI-part1 having a relatively high security requirement cannot be sent in a reserved RE when the number of HARQ-ACK information bits is not more than 2, the absence of HARQ-ACK transmission does not affect CSI-part1.

[0082] (3) CSI-part2 and UL-SCH may be sent in reserved REs (where only CSI-part2 may be sent in a UCI-only scenario).

[0083] (4) If there are HARQ-ACK information bits to be transmitted (ie, the number of HARQ-ACK information bits is 1 or 2), the HARQ-ACK is transmitted on the reserved RE. In other words, the reserved REs to which the CSI-part2 has been mapped are punctured (withdrawn) for the HARQ-ACK in this case.

[0084] In order to obtain the gain from frequency hopping, the PUSCH may be divided into two parts in the time domain, where the two parts are respectively called the first hop (hop 1) and the second hop (hop 2). The frequency domain resources in hop 1 and hop 2 are different. Accordingly, the HARQ-ACK, CSI-part1 and CSI-part2 are also mapped to hop 1 and hop 2 according to a preset rule.

[0085] The above mapping rule can be intuitively represented in FIG. 2. As shown in FIG. 2, CSI-part1 only maps to a non-reserved RE, and CSI-part2 has both a part mapped to reserved REs and a part mapped to a non-reserved RE. If there is a HARQ-ACK (ie, the number of information bits is 1 or 2), the HARQ-ACK is mapped to the reserved REs (in other words, the resource to which the encoded CSI-part2 bit was mapped is punctured).

[0086] The following rules apply to PUSCH frequency hopping:

[0087] The frequency hopping rule for the number of PUSCH symbols includes frequency hopping within a time slot (slot) and frequency hopping between time slots. The details are as follows:

; и количество символов в скачкообразной перестройке 2 равно общему количеству символов PUSCH за вычетом количества символов в скачкообразной перестройке 1, а именно,

.

представляет собой общее количество символов PUSCH в одном временном слоте.[0088] For intra-time slot frequency hopping, the number of symbols in hop 1 is rounding down half of the total number of PUSCH symbols down to the nearest integer, namely

; and the number of symbols in hop 2 is equal to the total number of PUSCH symbols minus the number of symbols in hop 1, namely,

.

is the total number of PUSCH symbols in one timeslot.

[0089] For frequency hopping between time slots, hop 1 and hop 2 are obtained by dividing based on the time slot in terms of time. For example, a hop with an even slot number is hop 1, and a hop with an odd slot number is hop 2.

[0090] Depending on the demodulation reference signal (DMRS) pattern, in the case of PUSCH frequency hopping specified in the current protocol, a possible case of intra-time slot frequency hopping includes: the number of symbols that can carry data in the hopping hop 1 is equal to the number of symbols that can carry data in hop 2; or the number of symbols that can carry data in hop 1 is 1 less than the number of symbols that can carry data in hop 2; and in the case of frequency hopping between time slots, the number of symbols that can carry data in hop 1 is equal to the number of symbols that can carry data in hop 2.

[0091] The frequency hopping split rule for the number of coded bits mapped to reserved REs is as follows:

, количества кодированных битов, отображенных на зарезервированные RE в скачкообразной перестройке 1 и скачкообразной перестройке 2, соответственно равны:[0092] Assuming that the number of coded bits mapped to the reserved REs is

, the numbers of coded bits mapped to reserved REs in hop 1 and hop 2, respectively, are:

можно точно разделить на

.[0093] The equal signs in formula (3) and formula (4) are valid only when

can be exactly divided into

.

[0094] According to the existing specification, in a UCI-only scenario, the numbers of encoded bits of the UCI parts (HARQ-ACK, CSI-part1 and CSI-part2) are also obtained by splitting according to a certain rule during frequency hopping. Before the split description, the following three parameters are defined:

определяется как индекс первого символа, который не включает в себя DMRS и который находится после первой группы последовательных символов DMRS. группа последовательных символов DMRS может включать в себя один символ DMRS или может включать в себя множество последовательных символов DMRS.[0097] The number of REs that can carry data in a PUSCH symbol after the first group of consecutive DMRS symbols in PUSCH hop 1:

.

is defined as the index of the first symbol that does not include the DMRS and that is after the first group of consecutive DMRS symbols. a group of consecutive DMRS symbols may include one DMRS symbol or may include a plurality of consecutive DMRS symbols.

[0098] The frequency hopping separation rules for the number of encoded bits of parts (HARQ-ACK, CSI-part1 and CSI-part2) of the UCI are as follows:

[0099] Frequency hopping split rule for number of HARQ-ACK coded bits:

количества кодированных битов HARQ-ACK, которые отправляются в скачкообразной перестройке 1 и скачкообразной перестройке 2, соответственно:[0100] Assuming that the number of HARQ-ACK encoded bits is,

formula (4) is satisfied to the left of the comma, then by combining formulas (5) and (6), we can find out the following:

[0105] Frequency hopping split rule for CSI-part2 encoded bits:

, то количества кодированных битов CSI-part2, которые отправляются в скачкообразной перестройке 1 и скачкообразной перестройке 2, соответственно, равны:[0106] Assuming that the number of coded bits of CSI-part2 is

, then the numbers of CSI-part2 coded bits that are sent in hop 1 and hop 2, respectively, are:

[0107] When the following three conditions exist in a UCI-only scenario, the CSI-part1 is incompletely sent.

[0108] Condition 1: The number of coded bits of CSI-part1 is exactly equal to the number of coded bits mapped to all REs that can carry data except for the reserved REs in PUSCH hop 1 and hop 2, i.e.:

не может быть точно разделено на

. Следовательно, в формуле (7) недопустим знак равенства, то есть:[0109] Condition 2:

cannot be exactly divided into

. Therefore, in formula (7) the equal sign is not allowed, that is:

[0110] Condition 3: The number of REs that are adapted to be used for data transfer and that have two frequency hopping resources are the same, that is, for PUSCH hop 1 and hop 2,

[0111] The following can be learned from formulas (8), (9), (11) and (12):

[0112] The following can be obtained by adding formulas (8) and (9):

[0113] From formulas (14) and (10), the following can be obtained:

[0114] From formulas (13) and (15), the following can be obtained:

[0115] From formulas (16) and (4), the following can be obtained:

[0116] Therefore, from formulas (9) and (17), the following can be learned:

[0117] That is, the number of coded bits of CSI-part1 in hopping 2 is greater than the number of coded bits mapped to the non-reserved RE, and CSI-part1 cannot be carried using the reserved RE. Therefore, CSI-part1 is not completely sent.

(формула (17)) могут быть зарезервированы RE, по которым не отправляются данные, как показано на Фиг. 3. Если PUSCH использует мультиплексирование с ортогональным частотным разделением, расширенное дискретным преобразованием Фурье с одной несущей (discrete Fourier transform spread orthogonal frequency division multiplexing, DFT-s-OFDM), вышеупомянутый RE, на котором не отправляются данные, может повредить характеристику низкого отношения пиковой к средней мощности (peak-to-average power ratio, PAPR) для одной несущей для передачи по восходящей линии связи в одном или более символах в скачкообразной перестройке 2.[0118] In addition, due to

(formula (17)) may be reserved by REs on which no data is sent, as shown in FIG. 3. If PUSCH uses orthogonal frequency division multiplexing extended by single carrier discrete Fourier transform (discrete Fourier transform spread orthogonal frequency division multiplexing, DFT-s-OFDM), the aforementioned RE on which no data is sent may damage the low peak ratio performance. to the average power (peak-to-average power ratio, PAPR) for one carrier for uplink transmission in one or more symbols in hopping 2.

[0119] In addition, the symbol used in the present application is a unit of time and may be an orthogonal frequency-division multiplexing (OFDM) symbol.

[0120] In this regard, the present application provides a communication method for solving the problem of incomplete sending of CSI-part1, and for solving the problem of performance degradation for one carrier when a signal is sent in hop 2 using a DFT-s-OFDM signal.

[0121] As shown in FIG. 4, the communication method includes the following steps.

[0122] S410. Receiving downlink control information, where downlink control information is used for PUSCH scheduling, PUSCH is used to carry only UCI, PUSCH includes a first frequency hopping resource and a second frequency hopping resource, and a time domain start symbol of the first hopping resource frequency is before the start symbol of the time domain resource of the second frequency hopping.

[0123] The fact that PUSCH is used to carry only UCI refers to a scenario with only UCI defined in the communication protocol. The first frequency hop resource and the second frequency hop resource are, for example, hop 1 and hop 2 described above. Optionally, the frequency domain resource of the first frequency hopping resource is different from the frequency domain resource of the second frequency hopping resource, and the difference means that the frequency domain resource of the first frequency hopping resource partially overlaps or does not overlap the frequency domain resource of the second frequency hopping resource. In addition, optionally, the end position of the time domain resource of the first frequency hopping is adjacent to the start position of the time domain resource of the second frequency hopping. Alternatively, the first hopping resource is sequential or non-sequential in the time domain and the second hopping resource is sequential or non-sequential in the time domain. The frequency hopping resource explanation can be applied to another method or implementation in the present application.

[0124] The downlink control information described in S410 is, for example, downlink control information (DCI) transmitted on the PDCCH. The base station may indicate, using different states of one bit in the DCI, whether the PUSCH is used to transmit only the UCI. In other words, whether the current communication scenario is a UCI-only scenario is indicated by various bit states.

[0125] S420. Sending the first UCI on PUSCH, where the first UCI includes at least one of HARQ-ACK, CSI-part1 and CSI-part2.

[0126] The number of coded bits that can be mapped to the reserved REs in the first frequency hopping resource is the first value, the number of coded bits that can be mapped to the reserved REs in the second frequency hopping resource is the second value, the first value is not less than the second value, and the reserved REs in the first frequency hopping resource and the reserved REs in the second frequency hopping resource are reserved for transmitting a potential HARQ-ACK that has 2 bits or less. Here, "transmission of a potential HARQ-ACK" is further explained. In this embodiment of the present application, the HARQ-ACK may be transmitted on the PUSCH or may not actually be transmitted. Regardless of whether a HARQ-ACK is sent, these REs shall be reserved. These reserved REs correspond to a specific number of coded bits to be mapped to the RE. In particular, the number of HARQ-ACK bits used in the "transmission of a potential HARQ-ACK" is not more than 2. In addition, the number of encoded bits mapped to the reserved REs is specially calculated based on the number of HARQ-ACK bits of 2. In this embodiment of the present application, if there is no actual transmission, the number of coded bits mapped to the reserved REs can be understood as the number of coded bits that can be mapped to the reserved RE, or the corresponding number of coded bits corresponding to the reserved RE.

[0127] The reason that the information in CSI-part1 is not completely sent is because the number of encoded bits that are related to CSI-part1 and which are mapped to the second hop resource is relatively small. In other words, the number of REs on the second hop resource that are used to map the CSI-part1 is relatively small, and therefore the CSI-part1 cannot be fully mapped to the second hop resource. Compared with the prior art, the present application reduces the number of coded bits that can be mapped to the reserved REs in the second hopping resource, thereby increasing the number of REs that are in the second hopping resource that are used to map CSI-part1. This solves the problem that, due to the UCI transmission by frequency hopping in the UCI-only scenario, the information in the CSI-part1 is not completely sent.

[0128] In addition, in the above solution, the number of reserved REs in the second hop resource is reduced, and the case in which no data is sent to the RE in the second hop resource is eliminated. Therefore, in method 400, the problem of incomplete sending of CSI-part1 is solved, and the problem shown in FIG. 3 is also solved.

[0129] It should be noted that "the number of coded bits that can be mapped to the reserved REs in the first frequency hopping resource is the first value, the number of coded bits that can be mapped to the reserved REs in the second frequency hopping resource is the second value , and the first value is not less than the second means that the number of reserved REs in the second hopping resource is reduced so that the second value is greater than or equal to the first value.

[0130] Optionally, method 400 further includes:

[0138] In this application, it should be noted that the first group of consecutive DMRS symbols starts with the first DMRS symbol on the corresponding resource in the time domain and ends with the last consecutive DMRS symbol. See details in FIG. 5. In FIG. 5, four PUSCH resources, namely PUSCH 1, PUSCH 2, PUSCH 3, and PUSCH 4, are shown from top to bottom (the top-down sequence is only used to logically distinguish between the four PUSCH resources, and does not impose restrictions on the position relation in the frequency domain). The start symbols of PUSCH 1 and PUSCH 3 are DMRS symbols, and the start symbols of PUSCH 2 and PUSCH 4 are not DMRS symbols. In addition, the first group of consecutive DMRS symbols in each of PUSCH 1 and PUSCH 2 includes only one symbol, and the first group of consecutive DMRS symbols in each of PUSCH 3 and PUSCH 4 includes a plurality of symbols.

Таблица 1 представляет собой результат, полученный с использованием способа из предшествующего уровня техники, а Таблица 2 представляет собой результат, полученный с использованием способа в настоящей заявки.[0152] The following uses several examples to describe the positive effects obtained when calculating using the communication method (for example, frequency hopping transmission is performed using

кодированных битов, отображаемых на зарезервированные RE в скачкообразной перестройке 2, больше, чем количество кодированных битов, которые относятся к CSI-part2 и которые отображаются в скачкообразную перестройку 2. Следовательно, для некоторых зарезервированных RE нет данных для отправки. Когда PUSCH использует DFT-s-OFDM, характеристика низкого PAPR для одиночной несущей нарушается.[0153] From the second last row and the third last row in Table 1, it can be seen that the number of coded bits transmitted on the non-reserved REs in hop 2 is different from the number of coded bits that belong to CSI-part1 and that are mapped to the non-reserved RE. Therefore, CSI-part1 cannot be fully carried on non-reserved REs in hop 2, and therefore CSI-part1 is not completely sent. From the last row and the fourth last row in Table 1, it can be seen that the number

There are more encoded bits mapped to reserved REs in hop 2 than the number of encoded bits that belong to CSI-part2 and are mapped to hop 2. Therefore, there is no data to send for some reserved REs. When PUSCH uses DFT-s-OFDM, the low PAPR performance for a single carrier is violated.

[0154] The above example is for description only.

кодированных битов, отображенных на зарезервированные RE в скачкообразной перестройке 2, равно количеству кодированных битов, которые относятся к CSI-part2 и которые отображаются в скачкообразную перестройку 2, и есть данные, которые должны быть отправлены по всем зарезервированным RE. Можно узнать, что в способе вычисления в настоящей заявке как количества кодированных битов, отображенных на не зарезервированные RE на двух скачкообразной перестройках, так и количества кодированных битов CSI-part1 на двух скачкообразной перестройках, являются согласованными, тем самым решая проблему известного уровня техники.[0155] Table 2 shows the calculation result using the communication method presented in this application. From the second last row and the third last row in Table 2, it can be seen that the number of coded bits transmitted on the non-reserved REs in hop 2 is the same as the number of coded bits that belong to CSI-part1 and are mapped to the non-reserved RE . From the last row and the fourth last row in table 2, you can find out that the number

of coded bits mapped to reserved REs in hop 2 is equal to the number of coded bits that belong to CSI-part2 and are mapped to hop 2, and there is data to be sent on all reserved REs. It can be recognized that, in the calculation method of the present application, both the number of coded bits mapped to non-reserved REs on the two hops and the number of coded bits of CSI-part1 on the two hops are consistent, thereby solving the problem of the prior art.

[0156] The frequency hopping division rule for the number of encoded HARQ-ACK bits provided in the prior art is as follows:

, количества кодированных битов HARQ-ACK, которые отправляются в скачкообразной перестройке 1 и скачкообразной перестройке 2, соответственно, равны:[0157] Assuming that the number of encoded HARQ-ACK bits is

, the numbers of encoded HARQ-ACK bits that are sent in hop 1 and hop 2, respectively, are:

[0158] A problem with the above split rule is that the non-reserved REs in hop 1 are not enough to carry the number of coded bits of CSI-part1 in hop 1, and hence the CSI-part1 is not completely sent.

[0159] The reasons are as follows:

справа от функции минимума

заключается в установке верхнего предела (называемого ниже первым верхним пределом снизу) для ресурса, занятого для CSI-part1 в скачкообразной перестройке 1, то есть CSI-part1 не может занимать ресурс для HARQ-ACK в скачкообразной перестройке 1. Однако, на основе спецификации в протоколе связи, CSI-part1 не может занимать зарезервированный ресурс RE в скачкообразной перестройке 1, то есть CSI-part1 не должна превышать верхний предел

(который называется вторым верхним пределом снизу).[0160] In the formula (X), the parameter selection function

to the right of the minimum function

is to set an upper limit (referred to below as the first lower upper limit) on the resource occupied for CSI-part1 in hop 1, i.e. CSI-part1 cannot occupy the resource for HARQ-ACK in hop 1. However, based on the specification in communication protocol, CSI-part1 cannot occupy the reserved RE resource in hop 1, that is, CSI-part1 must not exceed the upper limit

(which is called the second upper limit from the bottom).

является количеством кодированных битов, которое вычисляется на основе фактического количества информационных битов HARQ-ACK, и

является количеством кодированных битов, которое отображаются на зарезервированные RE и которое вычисляется на основе количества информационных битов HARQ-ACK, равного 2. Следовательно, если фактическое количество информационных битов HARQ-ACK равно 0 или 1, то

, и

для скачкообразной перестройки 1. В этом случае первый верхний предел больше второго верхнего предела. Следовательно, не зарезервированных RE в скачкообразной перестройке 1 может быть недостаточно для переноса количества

кодированных битов CSI-part1 в скачкообразной перестройке 1.[0161] When the number of HARQ-ACK information bits is 0, 1, or 2,

is the number of encoded bits, which is calculated based on the actual number of HARQ-ACK information bits, and

is the number of encoded bits that are mapped to the reserved REs and is calculated based on the number of HARQ-ACK information bits equal to 2. Therefore, if the actual number of HARQ-ACK information bits is 0 or 1, then

, and

for hopping 1. In this case, the first upper limit is greater than the second upper limit. Therefore, the non-reserved REs in hop 1 may not be sufficient to carry the number

encoded CSI-part1 bits in hop 1.

[0162] Accordingly, another communication method 600 is provided herein. Method 600 may be implemented based on the above method, or may be implemented in combination with the above method, or may be implemented independently. As shown in FIG. 6, the method includes the following steps:

[0163] S610. Receiving downlink control information, where downlink control information is used for PUSCH scheduling, PUSCH is used to carry only UCI, PUSCH includes a first frequency hopping resource and a second frequency hopping resource, and a time domain start symbol of the first hopping resource frequency is before the start symbol of the time domain resource of the second frequency hopping.

[0164] S620. Sending the first UCI on PUSCH, where the first UCI includes at least one of HARQ-ACK, CSI-part1 and CSI-part2.

bits that are related to CSI-part1 in the first UCI and that are mapped to the first frequency hopping resource is the smaller of the fourth value and the fifth value, the fourth value is determined based on the number

encoded bits of CSI-part1 in the first UCI, and the fifth value is determined based on the larger value in

Кроме того, CSI-part1 не может занимать зарезервированные RE в ресурсе первой скачкообразной перестройки частоты. То есть

, то не зарезервированных RE в ресурсе первой скачкообразной перестройки частоты может быть недостаточно для переноса количества

кодированных битов CSI-part1 на ресурсе первой скачкообразной перестройки частоты.[0166] In the prior art, the fifth value is only determined based on

. For example, the fifth value is

also should not be greater than the upper limit

(namely the second upper limit). When the number of HARQ-ACK information bits is 0, 1, or 2, then

is the number of encoded bits, which is calculated based on the actual number of HARQ-ACK information bits, and

is the number of encoded bits that is mapped to the reserved REs and is calculated based on the number of HARQ-ACK information bits equal to 2. Therefore, if the actual number of HARQ-ACK information bits is 0 or 1, then

and

. That is, on the resource of the first frequency hopping

. In this case, the first upper limit is greater than the second upper limit. In the prior art, if the fifth value is only determined based on

encoded CSI-part1 bits on the first hop resource.

[0171] Method 600 may be implemented separately or may be implemented in conjunction with method 400.

[0172] The present application also provides a communication method. As shown in FIG. 7, method 700 includes the following steps:

[0173] S710. Sending downlink control information, where the downlink control information is used for PUSCH scheduling, PUSCH is used to carry only UCI, PUSCH includes a first frequency hopping resource and a second frequency hopping resource, and a time domain start symbol of the first hopping resource frequency is before the start symbol of the time domain resource of the second frequency hopping.

[0174] S720. Reception of the first UCI in PUSCH, where the first UCI includes at least one of HARQ-ACK, CSI-part1 and CSI-part2, where the number of coded bits that can be mapped to reserved REs in the first hop resource is the first value, the number of coded bits that can be mapped to the reserved REs in the second frequency hopping resource is the second value, the first value is not less than the second value, and the reserved REs in the first frequency hopping resource and the Reserved REs in the second frequency hopping resource are reserved to transmit a potential HARQ-ACK that is 2 bits or less.

[0175] The reason that the information in CSI-part1 is not completely sent is that the number of encoded bits that are related to CSI-part1 and which are mapped to the resource of the second frequency hopping is relatively small. In other words, the number of REs on the second hop resource that are used to map the CSI-part1 is relatively small, and therefore the CSI-part1 cannot be fully mapped to the second hop resource. Compared with the prior art, the present application reduces the number of coded bits that can be mapped to the reserved REs in the second hopping resource, thereby increasing the number of REs that are in the second hopping resource that are used to map CSI-part1. This solves the problem that, due to the transmission of UCI by frequency hopping in a UCI-only scenario, the information in CSI-part1 is not completely sent.

[0176] One of skill in the art can understand that method 700 corresponds to method 400. For brevity, details are not repeated here.
