Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a resource mapping method and apparatus. Background Technology

[0002] The Physical Uplink Control Channel (PUCCH) is a physical channel in the uplink of a new radio (NR) system, used to carry uplink control information. The purpose of setting up the PUCCH is to allow terminal devices to transmit L1 / L2 control information, such as channel state reports (e.g., precoding matrix indicator (PMI) and channel quality indicator (CQI)), hybrid automatic repeat request (HARQ) acknowledgment (ACK) / negative acknowledgment (NACK), and scheduling requests, when they are not scheduled (i.e., not allocated uplink shared channel (UL-SCH) resources).

[0003] When the PUCCH overlaps with the physical uplink shared channel (PUSCH) in a single time slot, the uplink control information (UCI) on the PUCCH can be multiplexed onto the PUSCH. Alternatively, downlink control information (DCI) can be used to indicate the need for UCI feedback on the PUSCH.

[0004] However, when a PUSCH contains more than one codeword (CW), how to map UCI to the frequency and time domain resources of the PUSCH needs to be addressed. Summary of the Invention

[0005] This application provides a resource mapping method and apparatus that can reasonably determine the resources used for transmitting UCI.

[0006] In a first aspect, embodiments of this application provide a resource mapping method, the method being applied to a terminal device or a chip, the chip being disposed in the terminal device, the method comprising:

[0007] When the Physical Uplink Shared Channel (PUSCH) includes multiple codewords (CWs), resources for transmitting Uplink Control Information (UCI) are determined, wherein the PUSCH includes the UCI.

[0008] In this embodiment, when the PUSCH includes multiple CWs (Cross-Wave), i.e., when the number of CWs transmitted in the PUSCH includes at least two, the terminal device can determine the resources used for transmitting UCI. That is, the resources used for transmitting UCI need to be determined according to the method provided in this embodiment, and are not predetermined. It is understood that the resources used for transmitting UCI may include any one or more of spatial, temporal, or frequency domain resources used for UCI transmission. The method provided in this embodiment can reasonably and effectively determine the resources used for transmitting UCI, improving resource utilization efficiency.

[0009] In one possible implementation, determining the resources used for transmitting uplink control information (UCI) includes: determining the transport layer occupied by the UCI and / or the transport layer to be mapped by the UCI based on the bit length of the UCI and / or the information type included in the UCI, wherein the transport layer is the transport layer corresponding to the plurality of CWs.

[0010] The bit length of the UCI shown in this application embodiment can also be referred to as the number of bits of the UCI, etc. The transport layer occupied by the UCI refers to the transport layer that needs to be punctured, and the transport layer to be mapped by the UCI refers to the transport layer on which the UCI needs to be mapped. That is to say, the transport layer to be mapped by the UCI shown in this application embodiment refers to the transport layer on which the UCI will be mapped, and the transport layer occupied by the UCI may be empty or filled with other information.

[0011] In one possible implementation, determining the transport layer occupied by the UCI and / or the transport layer to be mapped by the UCI based on the bit length of the UCI includes: determining the transport layer occupied by the UCI and / or the transport layer to be mapped by the UCI based on whether the bit length of the UCI is less than or equal to a first value.

[0012] For example, when the bit length of the UCI is less than or equal to a first value, it can be said that the UCI includes feedback information (or that the UCI only includes feedback information). For example, the first value can be 2.

[0013] In one possible implementation, the UCI includes one or more of the following information types: feedback information (such as HARQ-ACK as shown below), first channel state information (CSI1 as shown below), or second CSI (CSI2 as shown below).

[0014] For example, the UCI may include feedback information. Optionally, the UCI may also include a first CSI and / or a second CSI. It is understood that the first CSI and the second CSI may be understood as different types of CSIs. For example, the first CSI may be CSI1, and the second CSI may be CSI2.

[0015] In one possible implementation, if the bit length of the UCI is less than or equal to the first value, or if the UCI includes feedback information, the transport layer occupied by the UCI is the transport layer corresponding to the first CW, and the transport layer to which the UCI is to be mapped is the transport layer corresponding to the first CW, wherein the first CW is the CW with the largest modulation and coding scheme MCS among the plurality of CWs; or, the transport layer occupied by the UCI is the transport layer corresponding to the plurality of CWs, and the transport layer to which the UCI is to be mapped is the transport layer corresponding to the plurality of CWs; or, the transport layer occupied by the UCI is the transport layer corresponding to the plurality of CWs, and the transport layer to which the UCI is to be mapped is the transport layer corresponding to the first CW, wherein the first CW is the CW with the largest modulation and coding scheme MCS among the plurality of CWs.

[0016] In one possible implementation, the method further includes: performing rate matching on the encoded bits of the UCI channel-coded data according to the bit length of the UCI and the number of transmission layers corresponding to the first CW; or, performing rate matching on the encoded bits of the UCI channel-coded data according to the bit length of the UCI and the number of transmission layers corresponding to the plurality of CWs; or, performing rate matching on the encoded bits of the UCI channel-coded data on the first CW according to the bit length of the UCI on the first CW and the number of transmission layers corresponding to the first CW, and performing rate matching on the encoded bits of the UCI channel-coded data on the second CW according to the bit length of the UCI on the second CW and the number of transmission layers corresponding to the second CW, wherein the second CW is one of the plurality of CWs.

[0017] In one possible implementation, when the bit length of the UCI is greater than a first value, or when the information types included in the UCI include feedback information, a first CSI, and a second CSI, the transmission layers occupied by the feedback information and the first CSI are the transmission layers corresponding to the first CW, and the transmission layers to be mapped by the feedback information and the first CSI are the transmission layers corresponding to the first CW, where the first CW is the CW with the largest modulation and coding scheme (MCS) among the plurality of CWs; the transmission layers occupied by the second CSI are the transmission layers corresponding to the plurality of CWs, and the transmission layers to be mapped by the second CSI are the transmission layers corresponding to the plurality of CWs.

[0018] In one possible implementation, the method further includes: performing rate matching on the coded bits of the feedback information channel encoded according to the bit length of the feedback information on the first CW and the number of transmission layers corresponding to the first CW; or, performing rate matching on the coded bits of the first CSI channel encoded according to the bit length of the first CSI on the first CW and the number of transmission layers corresponding to the first CW; or, performing rate matching on the coded bits of the second CSI channel encoded according to the bit length of the second CSI and the number of transmission layers corresponding to the plurality of CWs.

[0019] Alternatively, the above implementation can also be understood as follows: determining the rate matching output of the encoded bits after channel coding of the feedback information based on the bit length of the feedback information on the first CW and the number of transmission layers corresponding to the first CW; or determining the rate matching output of the encoded bits after channel coding of the first CSI based on the bit length of the first CSI on the first CW and the number of transmission layers corresponding to the first CW; or determining the rate matching output of the encoded bits after channel coding of the second CSI based on the bit length of the second CSI and the number of transmission layers corresponding to the plurality of CWs.

[0020] In one possible implementation, if the bit length of the UCI is greater than a first value, or if the information type included in the UCI includes feedback information, a first CSI, and a second CSI, the transmission layers occupied by the feedback information included in the UCI, the first channel state information (CSI) in the UCI, and the second CSI are respectively the transmission layers corresponding to the plurality of CWs, and the transmission layers to be mapped by the feedback information, the first channel state information (CSI) in the UCI, and the second CSI are respectively the transmission layers corresponding to the plurality of CWs.

[0021] In one possible implementation, the method further includes: performing rate matching on the encoded bits of the feedback information channel encoded on the first CW according to the bit length of the feedback information on the first CW and the number of transmission layers corresponding to the first CW; and performing rate matching on the encoded bits of the feedback information channel encoded on the second CW according to the bit length of the feedback information on the second CW and the number of transmission layers corresponding to the second CW; or, performing rate matching on the encoded bits of the first CSI channel encoded on the first CW according to the bit length of the first CSI on the first CW and the number of transmission layers corresponding to the first CW; and performing rate matching on the encoded bits of the first CSI channel encoded on the second CW according to the bit length of the first CSI on the second CW and the number of transmission layers corresponding to the second CW; or, performing rate matching on the encoded bits of the second CSI channel encoded according to the bit length of the second CSI and the number of transmission layers corresponding to the plurality of CWs.

[0022] Alternatively, the above implementation can also be understood as follows: determining the rate matching output of the encoded bits after channel coding of the feedback information on the first CW based on the bit length of the feedback information on the first CW and the number of transmission layers corresponding to the first CW; and determining the rate matching output of the encoded bits after channel coding of the feedback information on the second CW based on the bit length of the feedback information on the second CW and the number of transmission layers corresponding to the second CW; or, determining the rate matching output of the encoded bits after channel coding of the first CSI on the first CW based on the bit length of the first CSI on the first CW and the number of transmission layers corresponding to the first CW; and determining the rate matching output of the encoded bits after channel coding of the first CSI on the second CW based on the bit length of the first CSI on the second CW and the number of transmission layers corresponding to the second CW; or, determining the rate matching output of the encoded bits after channel coding of the second CSI based on the bit length of the second CSI and the number of transmission layers corresponding to the plurality of CWs.

[0023] In one possible implementation, the method further includes: transmitting the plurality of CWs and the UCI via the PUSCH.

[0046] In this embodiment, the network device may be a device with wireless transceiver functionality or a chip that can be configured in the device.

Figure 1 The communication system shown includes, but is not limited to, network equipment and terminal equipment, and may also include other communication equipment. Figure 1 The number and form of the devices shown are for illustrative purposes and do not constitute a limitation on the embodiments of this application.

[0048] Figure 2 This is a schematic diagram of a UCI mapping onto time-frequency resources provided in an embodiment of this application. Figure 2 This illustrates how uplink control information is mapped to resource elements (REs) when transmitted on the PUSCH. It is understandable that... Figure 2 In the diagram shown, the horizontal axis represents time-domain resources, and the vertical axis represents frequency-domain resources. For example, Figure 2 The horizontal axis of a square shown represents an orthogonal frequency division multiplexing (OFDM) symbol, and the vertical axis represents a subcarrier. Thus, one square can represent one RE. It is understood that the relationship between OFDM symbols, subcarriers, and REs shown here is merely an example. As standard technologies evolve, the composition of REs may vary, and this application does not limit this.

[0049] For example, uplink control information includes demodulation reference signal (DMRS), HARQ-ACK, channel state information (CSI) 1, and CSI 2.

[0050] For example, within each hop of PUSCH:

[0051] HARQ-ACK starts mapping from the first OFDM symbol after the symbol occupied by DMRS;

[0052] CSI1 starts mapping from the first OFDM symbol not occupied by DMRS in PUSCH, and cannot be mapped to the RE position reserved for HARQ-ACK, or the RE mapping position of HARQ-ACK, and is not frequency-division multiplexed with PUSCH DMRS;

[0053] CSI2 starts mapping from the first OFDM symbol not occupied by PUSCH DMRS. It can be mapped to the RE position reserved for HARQ-ACK, but cannot be mapped to the HARQ-ACK RE mapping position, nor can it be mapped to the CSI1 RE mapping position. It is not frequency-division multiplexed with PUSCH DMRS.

[0054] It can be understood that each hop shown above can be interpreted as a hop in the frequency domain. For example, if a PUSCH occupies 14 OFDM symbols, then the first 7 OFDM symbols can occupy one frequency domain position, and the last 7 OFDM symbols can occupy another frequency domain position.

[0055] The RE positions occupied by HARQ-ACK, CSI1, and CSI2 on each OFDM symbol are as follows: The REs for uplink control information mapping adopt distributed mapping, and the interval d is:

[0056] If the number of unmapped uplink control information modulation symbols (i.e., the symbols modulated by the uplink control information) after scheduling is greater than the number of available REs on the OFDM symbol, then d = 1. If there are still unmapped modulation symbols, then the mapping continues in the next OFDM symbol. If the number of unmapped uplink control information modulation symbols after scheduling is less than the number of available REs on the OFDM symbol, then d = floor(number of available REs on the OFDM symbol / number of modulation symbols of the uplink control information after scheduling).

[0057] For example, Figure 2 Nine OFDM symbols are shown, and the number of REs available on one OFDM symbol is 24. For example, for HARQ-ACK, since its corresponding modulation symbols number 28, and 28 is greater than 24, therefore, in the second OFDM symbol (such as...) Figure 2 As shown in 1), d = 1. The number of remaining unmapped modulation symbols is 4. 4 is less than 24, therefore d = floor(24 / 4) = 6 (as shown in 1) Figure 2 (In this context, every 6 REs can map to one remaining unmapped modulation symbol). This is understandable. Figure 2 The structures shown are merely examples and should not be construed as limiting the embodiments of this application.

[0058] Since the ACK or NACK reported by the UE is crucial for the correct processing of downlink transmissions, ACK / NACK is transmitted on the RE immediately adjacent to the DMRS, thereby enabling more accurate channel estimation. This is especially important under conditions of high Doppler shift, where channel conditions may change within a single slot.

[0059] Because downlink data transmission is timed relative to the corresponding ACK / NACK, the base station knows when to receive ACK / NACK from the UE, thus ensuring correct decoding of the ACK / NACK and data portions. However, there are cases where the base station sends the Physical Downlink Control Channel (PDCCH) for downlink scheduling, but the UE does not receive it (e.g., discontinuous reception, DTX). In this case, the UE will not send ACK / NACK back to the base station. However, the base station expects to receive ACK or NACK, leading to a mismatch between the UE's encoding method and the base station's decoding method. In other words, if rate matching depends on whether ACK or NACK is sent, it may cause UL-SCH decoding failure. To avoid this error, in the UL-SCH bitstream, when the bit length of ACK or NACK is less than or equal to 2 bits, its occupied RE resources are punctured to remove mapped data or other uplink control information, so that the unpunctured bits are unaffected by the presence or absence of ACK or NACK. When the bit length of ACK or NACK is greater than 2 bits, rate matching can be used.

[0060] CSI is mainly used for low to medium levels of Doppler shift, where the channel quality is relatively stable. Therefore, no special matching method is required, and rate matching is used uniformly.

[0061] For example, for Type I and Type II CSI feedback on the PUSCH (the configuration of Type I and Type II is configured by IE CodebookConfig), the CSI report consists of two parts, where CSI1 (also known as part 1) has a fixed payload size and is used to identify the information bit length in CSI2 (also known as part 2). Part 1 should be transmitted completely before Part 2 (CSI2).

[0062] For example, for Type I CSI feedback, CSI1 includes the following information: rank indicator (RI) (if reported), CSI-RS resource indicator (CRI) (if reported), and CQI for the first codeword. The first codeword referred to here is the first CW for the downlink PDSCH. CSI2 contains the pre-coding matrix indicator (PMI) (if reported), and the CQI for the second codeword if the RI (if reported) is greater than 4. The second codeword referred to here is the second CW for the downlink PDSCH. For Type II CSI feedback, CSI 1 includes: RI (if reported), CQI, and an indicator of the non-zero bandwidth amplitude coefficients for each layer of Type II CSI, and the fields included in CSI1 are encoded separately. CSI2 contains the PMI for Type II CSI. CSI1 and CSI2 are encoded separately.

[0063] It is understood that the information shown above is only an example. For specific explanations of UCI, please refer to relevant standards or protocols. This application does not limit the scope of the embodiments.

[0064] This application addresses how to determine the resources used for UCI transmission when a PUSCH contains more than one CW, such as two or more CWs. Understandably, before introducing the resource mapping method provided in this application, the UCI processing procedure will be briefly described below.

[0065] For example, Figure 3 This is a schematic diagram illustrating a method for processing UCI according to an embodiment of this application. This method can be applied to terminal devices or chips. Figure 3 As shown, the process of transmitting UCI on the PUSCH can be described as follows:

[0066] 301. The terminal device generates the bit sequence of UCI.

[0067] For example, a terminal device can generate a UCI based on the information type. For instance, a UCI might include HARQ-ACK.

[0068] This generates the HARQ-ACK bit sequence. For example, UCI includes HARQ-ACK, CSI1, and CSI2.

[0069] This generates a bit sequence that includes the HARQ-ACK, CSI1, and CSI2.

[0070] 302. The terminal device performs code block segmentation and adds cyclic redundancy check (CRC) to the bit sequence of UCI.

[0071] 303. After segmenting the bit sequence of UCI into code blocks and adding CRC, the terminal equipment performs channel coding and rate matching on the channel-coded bit sequence.

[0072] For example, the rate-matched input bit sequence is Where r represents the code block number, N r This indicates the number of coded bits in the code block numbered r.

[0073] Output sequence length for rate matching E UCI =N L ·Q' ACK ·Q m Among them, C UCI N represents the number of code blocks in the UCI. L Q represents the transport layer number of PUSCH. m This indicates the modulation order of the PUSCH. For example, taking HARQ-ACK as an example, the output bit sequence after rate matching is... E r It is the length of the code block numbered r after rate matching. Therefore, the number of symbols in the above HARQ-ACK transmission can be represented by Q′. ACK This means that Q′ ACK It can be obtained from the following formula:

[0074]

[0075] Among them, O ACK This indicates the number of bits in the HARQ-ACK (also referred to as the bit length or number of bits of the HARQ-ACK, etc.); L ACK Indicates the number of CRCs added in HARQ-ACK; C UL-SCH This indicates the number of UL-SCH code blocks transmitted on the PUSCH. If the DCI format of the scheduled PUSCH includes a code block group (CBG) transmission information (CBGTI) field, which indicates that the UE should not transmit code block number r, then K r =0; otherwise, it is the size of the code block numbered r of UL-SCH transmitted on PUSCH. This represents the scheduling bandwidth of the PUSCH, expressed as the number of subcarriers. This indicates the number of subcarriers on OFDM symbol l carrying PTRS during PUSCH transmission. This indicates the number of REs available for UCI transmission on OFDM symbol 1 during PUSCH transmission. in, This is the total number of OFDM symbols transmitted in the PUSCH, including all OFDM symbols used for DMRS: for any OFDM symbol in the PUSCH carrying DMRS, For any OFDM symbol in PUSCH that does not carry DMRS, α is configured by the higher-layer parameter scaling, and l0 represents the index of the first OFDM symbol in the PUSCH transmission that does not carry DMRS, located after the OFDM symbol occupied by the first DMRS. It is understood that the above only exemplifies the rate matching method of HARQ-ACK; for specific explanations of rate matching for CSI1 and CSI2, please refer to HARQ-ACK, which will not be detailed here.

[0076] As can be seen from the above description, the input and output sequences for UCI rate matching need to be determined based on the number of transmission layers in the PUSCH. The output sequence for UL-SCH rate matching also needs to consider the influence of UCI. However, when the PUSCH includes at least two CWs, the method described below for determining which CW(s) determines the number of transmission layers can be found in this application.

[0077] 304. The terminal equipment determines the resources used for transmitting UCI by concatenating the encoded bits of UCI through code blocks.

[0078] In other words, by concatenating code blocks, the terminal device can determine the position of the UCI in the PUSCH resource. For example, the terminal device can first determine the position that can be used to map control information (such as UCI), and then determine the position that can be used to map data information. Alternatively, the terminal device can first determine the position used to map data information, and then determine the position used to map control information (such as UCI). It can be understood that the positions shown here can be any one or more of spatial, temporal, or frequency domain resources. For example, the terminal device can first determine the transport layer used to map UCI, and then determine the transport layer used to map data information. Alternatively, the terminal device can first determine the transport layer used to map data information, and then determine the transport layer used to map UCI.

[0079] It is understood that the specific method by which the terminal device determines the resources used for transmitting UCI can be referred to the method shown below in this application.

[0080] 305. The terminal equipment performs one or more of the following on the bits of UCI and data information: scrambling, modulation, layer mapping, precoding, or RE mapping.

[0081] Understandably, the terminal device modulates and maps the UCI and data information before sending the PUSCH.

[0082] Understandable Figure 3 The methods shown are merely examples, and the embodiments of this application do not limit the specific steps or processes for terminal devices to process UCI.

[0083] Figure 4 This is a flowchart illustrating a resource mapping method provided in an embodiment of this application. This method can be applied to terminal devices or chips. For ease of description, the method provided in this embodiment will be described below using a terminal device as an example. Figure 4 As shown, the method includes:

[0084] 401. When the PUSCH includes multiple CWs, the terminal device determines the resources used for transmitting UCI.

[0085] In this embodiment, UCI can be multiplexed into a PUSCH. When UCI is multiplexed into a PUSCH, and the PUSCH includes multiple CWs, the terminal device can determine the resources used for transmitting UCI. For example, these resources may include spatial resources, which may include the transport layer. Optionally, these resources may also include time-domain resources and / or frequency-domain resources.

[0086] For ease of description, the method provided in this application embodiment will be illustrated below using multiple CWs, including a first CW and a second CW, as an example. It is understood that the first CW has the strongest MCS among the multiple CWs. That is, the CW with the largest MSC among the multiple CWs is the first CW.

[0087] Optionally, the terminal device can determine the transport layer occupied by the UCI and / or the transport layer to be mapped by the UCI based on the bit length of the UCI and / or the type of information included in the UCI. The bit length of the UCI shown in this embodiment can also be referred to as the number of bits of the UCI, etc. The transport layer occupied by the UCI refers to the transport layer that needs to be punctured, and the transport layer to be mapped by the UCI refers to the transport layer on which the UCI needs to be mapped. That is, the transport layer to be mapped by the UCI shown in this embodiment refers to the transport layer on which the UCI will be mapped, while the transport layer occupied by the UCI may be empty or filled with other information.

[0088] For example, the terminal device can determine the transport layer occupied by the UCI and / or the transport layer to be mapped by the UCI based on whether the bit length of the UCI is less than or equal to a first value. For instance, if the bit length of the UCI is less than or equal to 2 bits, it indicates that the UCI includes feedback information, such as HARQ-ACK or HARQ-NACK. As another example, if the bit length of the UCI is greater than 2 bits, it indicates that the UCI includes not only HARQ-ACK but also a first CSI and / or a second CSI.

[0089] It is understood that when the bit length of the UCI is less than or equal to 2 bits, the method by which the terminal device determines the resources used for transmitting the UCI can be referred to in Embodiments 1 to 4 below. When the bit length of the UCI is greater than 2 bits, the method by which the terminal device determines the resources used for transmitting the UCI can be referred to in Embodiments 5 and 6 below.

[0090] For example, the terminal device can also directly determine the transport layer occupied by the UCI and / or the transport layer to be mapped by the UCI based on the type of information included in the UCI. For example, the UCI may only include feedback information, such as HARQ-ACK or HARQ-NACK, or the UCI may include feedback information as well as a first CSI and / or a second CSI. It is understood that a detailed explanation of when the UCI only includes feedback information can be found in Embodiments 1 to 4 below. A detailed explanation of when the UCI includes not only feedback information but also a first CSI and / or a second CSI can be found in Embodiments 5 and 6 below.

[0091] 402. The terminal device maps the UCI according to the transport layer to be mapped.

[0092] 403. The terminal device transmits multiple CWs and UCIs via the PUSCH. Correspondingly, the network device receives the PUSCH.

[0093] The method provided in this application embodiment can reasonably and effectively determine the resources used for UCI transmission, thereby improving resource utilization efficiency.

[0094] To provide a detailed explanation of the method by which a terminal device determines the resources used for transmitting UCI, specific embodiments will be used for illustration. The following embodiments will illustrate how UCI is mapped to PUSCH resources when a PUSCH includes multiple CWs, including one or more of time-domain resources, frequency-domain resources, and spatial-domain resources. For example, the following will illustrate whether the selection of different CWs is considered when HARQ-ACK (and / or configured grant UCI, CG-UCI) and CSI1 or CSI2 are mapped to PUSCH resources.

[0095] Example 1

[0096] The strongest MCS CW has corresponding holes punched and layered mapping.

[0097] In other words, the transport layer occupied by the UCI is the transport layer corresponding to the first CW, and the transport layer to be mapped by the UCI is the transport layer corresponding to the first CW. For example, when the PUSCH includes at least two CWs, the modulation symbols of the HARQ-ACK can be mapped to the transport layer corresponding to the CW with the larger MCS among the at least two CWs. Simultaneously, the UCI multiplexing the PUSCH can perform rate matching based on the number of transport layers of the CW with the larger MCS among the at least two CWs. For instance, the terminal device can perform rate matching on the coded bits after UCI channel coding based on the bit length of the UCI and the number of transport layers corresponding to the first CW. Alternatively, it can be understood that the terminal device can determine the rate-matched output of the coded bits after UCI channel coding based on the bit length of the UCI and the number of transport layers corresponding to the first CW.

[0098] For example, PUSCH includes CW1 and CW2. CW1 has 4 transport layers and a corresponding MCS of 6, while CW2 has 2 transport layers and a corresponding MCS of 5. The terminal device can then perform rate matching for UCI based on the number of transport layers in CW1 (this can also be understood as determining the rate-matched output of UCI based on the number of transport layers in CW1) and map it onto the transport layer corresponding to CW1 (i.e., its corresponding layer 4). For example, if UCI requires 20 coded symbols, corresponding to 20 RE resources, and CW1 has 4 transport layers, then each layer in the transport layer corresponding to CW1 can be allocated 5 coded symbols, and each layer can also correspond to 5 RE resources. Therefore, the coded symbols for HARQ-ACK can be mapped to these 20 RE resources. In other words, the coded symbols for UCI can be evenly distributed across the transport layer corresponding to CW1. Optionally, each layer can use... Figure 2 The method shown is used to map time-frequency resources. For example, the same information is transmitted at each layer, but different scrambling is used at different layers, thereby improving diversity gain.

[0099] In this embodiment of the application, by selecting the strongest CW, a CW with better channel conditions can be found, thereby ensuring transmission quality.

[0100] Example 2

[0101] All transport layers in all CWs are perforated and mapped in layers.

[0102] In other words, the transport layer occupied by UCI is the transport layer corresponding to multiple CWs (such as the sum of the transport layers corresponding to these multiple CWs), and the transport layer to be mapped by UCI is the transport layer corresponding to these multiple CWs (i.e., each layer corresponding to each CW maps to UCI). For example, when PUSCH includes at least two CWs, the modulation symbols of HARQ-ACK can be mapped to the transport layer corresponding to each of the at least two CWs.

[0103] Simultaneously, the UCI multiplexing of the PUSCH can perform rate matching based on the sum of the transmission layers of the at least two CWs. For example, the terminal device can perform rate matching on the coded bits after UCI channel coding based on the bit length of the UCI and the sum of the transmission layers of the at least two CWs. Alternatively, it can be understood that the terminal device can determine the rate-matched output of the coded bits after UCI channel coding based on the bit length of the UCI and the sum of the transmission layers of the at least two CWs.

[0104] For example, the data blocks to be transmitted on the PUSCH include CW1 and CW2. CW1 has 4 transport layers and its corresponding MCS is 6, while CW2 has 2 transport layers and its corresponding MCS is 5. The terminal device can then perform rate matching for UCI based on the sum of the transport layers of CW1 and CW2 (i.e., 2+4=6), and punch UL-SCH holes and map them on the transport layers corresponding to CW1 and CW2 (i.e., layer 6).

[0105] In this embodiment of the application, by punching holes at corresponding positions of all layers in all CWs and performing layer mapping, the resources of each layer can be fully utilized.

[0106] Example 3

[0107] All layers of all CWs are punched with holes, and only the layers of the strongest MCS CWs are mapped, and then mapped layer by layer.

[0108] In other words, the transport layer occupied by UCI is the transport layer corresponding to multiple CWs (such as the sum of the transport layers corresponding to these multiple CWs), and the transport layer to be mapped by UCI is the transport layer corresponding to the first CW (i.e., UCI is only mapped on the transport layer corresponding to the CW with the largest MCS). For example, when the PUSCH includes at least two CWs, the modulation symbols of HARQ-ACK can be applied to the transport layer of the CW with the largest MCS among these at least two CWs. Simultaneously, the UCI multiplexed from this PUSCH can be rate-matched according to the number of transport layers of the CW with the largest MCS among these at least two CWs. For example, the terminal device can rate-match the coded bits after UCI channel coding according to the bit length of UCI and the number of transport layers corresponding to the first CW. Alternatively, it can be understood that the terminal device can determine the rate-matched output of the coded bits after UCI channel coding based on the bit length of UCI and the number of transport layers corresponding to the first CW.

[0109] For example, the data blocks to be transmitted on the PUSCH include CW1 and CW2. CW1 has 4 transport layers and a corresponding MCS of 6, while CW2 has 2 transport layers and a corresponding MCS of 5. The terminal device can then perform rate matching based on the transport layer number of CW1 (i.e., 4). It will only perform puncturing mapping at the corresponding positions on these 4 layers (i.e., the transport layers corresponding to CW1). Optionally, the corresponding positions on the 2nd layer of CW2 can only be punctured without mapping UCI; or, the corresponding positions on the 2nd layer of CW2 can be filled with fixed values, such as NACK encoded information. In other words, when punching UL-SCH with UCI, puncturing can be performed on all 6 corresponding positions, but mapping will only occur on the 4th layer corresponding to CW1.

[0110] Through the embodiments of this application, interference from other CWs on the UCI mapping position can be effectively reduced.

[0111] Example 4

[0112] Rate matching is based on the number of transmission layers per CW (as shown above, N). L The rate zone output for each CW is calculated separately.

[0113] The UCI occupies the transport layers corresponding to multiple Channel Warp Views (CWs) (e.g., the sum of the transport layers corresponding to these multiple CWs), and the transport layers to be mapped by the UCI are the transport layers corresponding to these multiple CWs (i.e., each layer corresponding to each CW maps to the UCI). Simultaneously, the UCIs multiplexed by this PUSCH can be rate-matched separately. For example, the terminal device can perform rate matching on the coded bits of the UCI channel-coded on the first CW based on the bit length of the UCI on the first CW and the number of transport layers corresponding to the first CW, and perform rate matching on the coded bits of the UCI channel-coded on the second CW based on the bit length of the UCI on the second CW and the number of transport layers corresponding to the second CW. Alternatively, it can be understood that the terminal device can determine the rate-matching output of the coded bits of the UCI channel-coded on the first CW based on the bit length of the UCI on the first CW and the number of transport layers corresponding to the first CW, and determine the rate-matching output of the coded bits of the UCI channel-coded on the second CW based on the bit length of the UCI on the second CW and the number of transport layers corresponding to the second CW.

[0114] For example, the data blocks to be transmitted on the PUSCH include CW1 and CW2. CW1 has 4 transport layers and a corresponding MCS of 6, while CW2 has 2 transport layers and a corresponding MCS of 5. The terminal device can then calculate the UCI output on CW1 based on the number of transport layers of CW1, and calculate the UCI output on CW2 based on the number of transport layers of CW2. That is, UCI rate matching calculates the CW1 output based on 4 layers and the CW2 output based on 2 layers. Simultaneously, UCI punctures the UL-SCH on both CW1 and CW2 and maps them.

[0115] It is understood that the methods shown in Embodiments 1 to 4 are illustrated when the bit length of the UCI is less than or equal to 2 bits, or when the UCI only includes HARQ-ACK. Embodiments 5 and 6 below will describe in detail the methods when the bit length of the UCI is greater than 2 bits, or when the UCI includes HARQ-ACK and also includes CSI1 and / or CSI2.

[0116] Example 5

[0117] When UCI includes HARQ-ACK or CSI1, the rate matching of UCI determines the rate matching output based on the transmission layer number of the maximum MCS CW and performs layer mapping.

[0118] In other words, when the UCI includes HARQ-ACK and / or CSI1, the transport layers of HARQ-ACK and / or CSI1 are respectively the transport layers corresponding to the first CW (i.e., the transport layer corresponding to the CW with the largest MCS among multiple CWs), and the transport layers to be mapped by HARQ-ACK and / or CSI1 are respectively the transport layers corresponding to the first CW. Simultaneously, the rate matching method for HARQ-ACK and / or CSI1 can be: rate matching based on the number of transport layers corresponding to the first CW. That is, the terminal device can perform rate matching on the encoded bits of the HARQ-ACK channel-coded data based on the bit length of HARQ-ACK on the first CW and the number of transport layers corresponding to the first CW; and / or, perform rate matching on the encoded bits of the CSI1 channel-coded data based on the bit length of CSI1 on the first CW and the number of transport layers corresponding to the first CW. Alternatively, it can be understood that the terminal device can determine the rate matching output of the encoded bits after HARQ-ACK channel coding based on the bit length of HARQ-ACK on the first CW and the number of transmission layers corresponding to the first CW; and / or, determine the rate matching output of the encoded bits after CSI1 channel coding based on the bit length of CSI1 on the first CW and the number of transmission layers corresponding to the first CW.

[0119] For example, the data blocks to be transmitted on the PUSCH include CW1 and CW2. CW1 has 4 transmission layers and its corresponding MCS is 6, while CW2 has 2 transmission layers and its corresponding MCS is 5. UCI rate matching is then calculated based on 4 layers (i.e., the transmission layer corresponding to the CW with the larger MCS) and is mapped only on these 4 layers.

[0120] When UCI includes CSI2, all layers of all channels (CWs) are rate-matched and mapped hierarchically. That is, the transport layers occupied by CSI2 are the sum of the transport layers corresponding to multiple CWs, and the transport layers to be mapped for CSI2 are also the sum of the transport layers corresponding to multiple CWs. Simultaneously, the terminal device can perform rate matching on the coded bits after CSI2 channel coding based on the bit length of CSI2 and the sum of the number of transport layers corresponding to the multiple CWs. In other words, the terminal device can calculate the rate-matched output of the coded bits after CSI2 channel coding based on the bit length of CSI2 and the sum of the number of transport layers corresponding to the multiple CWs.

[0121] For example, the data blocks to be transmitted on the PUSCH include CW1 and CW2. CW1 has 4 transport layers and its corresponding MCS is 6, while CW2 has 2 transport layers and its corresponding MCS is 5. UCI rate matching is calculated based on 6 layers (i.e., the sum of the transport layers corresponding to CW1 and CW2). UCI rate matching is performed on the UL-SCH and mapped for CW1 and CW2.

[0122] It is understood that the method shown in Example 5 can be applied to any one or more of the following:

[0123] UCI includes HARQ-ACK, and the bit length of the HARQ-ACK is greater than 2 bits; UCI includes CSI1; UCI includes CSI2; UCI includes HARQ-ACK and CSI1; UCI includes HARQ-ACK and CSI2; UCI includes HARQ-ACK, CSI1 and CSI2; UCI includes CSI1 and CSI2, etc.

[0124] Example 6

[0125] The transmission layers occupied by HARQ-ACK, CSI1, and CSI2 in the UCI are the transmission layers corresponding to multiple CWs, and the transmission layers to be mapped are the transmission layers corresponding to multiple CWs. When the PUSCH includes at least two CWs, the modulation symbols of HARQ-ACK, CSI1, and CSI2 can be mapped to the transmission layer corresponding to each of the at least two CWs.

[0126] Optionally, the rate matching method for CSI2 can be: the terminal device can perform rate matching on the encoded bits of the CSI2 channel encoding based on the bit length of the CSI2 and the sum of the transmission layer numbers corresponding to multiple CWs. That is, the terminal device can determine the rate matching output of the encoded bits of the CSI2 channel encoding based on the bit length of the CSI2 and the sum of the transmission layer numbers corresponding to multiple CWs.

[0127] For the case where UCI includes CSI2, all layers of all CWs are RM and mapped layer by layer. For example, if 1CW has 4 layers and 2CW has 2 layers, the UCI rate matching is calculated based on 6 layers. UCI is mapped in CW1 and CW RM UL-SCH.

[0128] Optionally, the HARQ-ACK rate matching method can be as follows: rate matching is performed on the encoded bits of the HARQ-ACK channel encoded on the first CW based on the bit length of the HARQ-ACK on the first CW and the number of transmission layers corresponding to the first CW; and rate matching is performed on the encoded bits of the HARQ-ACK channel encoded on the second CW based on the bit length of the HARQ-ACK on the second CW and the number of transmission layers corresponding to the second CW. That is, the rate matching output of the encoded bits of the HARQ-ACK channel encoded on the first CW is determined based on the bit length of the HARQ-ACK on the first CW and the number of transmission layers corresponding to the first CW, and the rate matching output of the encoded bits of the HARQ-ACK channel encoded on the second CW is determined based on the bit length of the HARQ-ACK on the second CW and the number of transmission layers corresponding to the second CW.

[0129] Optionally, the CSI1 rate matching method can be as follows: rate matching is performed on the encoded bits of the CSI1 channel encoded on the first CW according to the bit length of CSI1 on the first CW and the number of transmission layers corresponding to the first CW; and rate matching is performed on the encoded bits of the CSI1 channel encoded on the second CW according to the bit length of CSI1 on the second CW and the number of transmission layers corresponding to the second CW. That is, the rate matching output of the encoded bits of the CSI1 channel encoded on the first CW is determined based on the bit length of CSI1 on the first CW and the number of transmission layers corresponding to the first CW, and the rate matching output of the encoded bits of the CSI1 channel encoded on the second CW is determined based on the bit length of CSI1 on the second CW and the number of transmission layers corresponding to the second CW.

[0130] In other words, for cases where UCI includes HARQ-ACK and / or CSI1, the UCI multiplexed by the PUSCH can be rate matched separately. For example, the terminal device can perform rate matching on the encoded bits of the UCI channel encoded on the first CW based on the bit length of the UCI on the first CW and the number of transmission layers corresponding to the first CW, and perform rate matching on the encoded bits of the UCI channel encoded on the second CW based on the bit length of the UCI on the second CW and the number of transmission layers corresponding to the second CW. Alternatively, it can be understood that the terminal device can determine the rate matching output of the encoded bits of the UCI channel encoded on the first CW based on the bit length of the UCI on the first CW and the number of transmission layers corresponding to the first CW, and determine the rate matching output of the encoded bits of the UCI channel encoded on the second CW based on the bit length of the UCI on the second CW and the number of transmission layers corresponding to the second CW.

[0131] For example, if CW1 (MCS6) has 4 layers and CW2 (MCS5) has 2 layers, UCI rate matching calculates the CW1 output based on the 4 layers and the CW2 output based on the 2 layers. UCI is mapped in CW1 and CW2 RM UL-SCH.

The device can be a terminal device, a component within a terminal device, or a device compatible with a terminal device. Figure 5 The communication device 500 shown may include a processing unit 501 and a communication unit 502. The processing unit 501 is used for data processing. The communication unit 502 integrates a receiving unit and a transmitting unit. The communication unit 502 may also be called a transceiver unit. Alternatively, the communication unit 502 may be split into a receiving unit and a transmitting unit. The processing unit 501 and communication unit 502 are similarly described below and will not be repeated. Wherein:

[0133] Processing unit 501 is used to determine the resources for transmitting uplink control information (UCI) when the physical uplink shared channel (PUSCH) includes multiple codewords (CWs). The PUSCH includes the aforementioned UCI.

[0134] Optionally, the processing unit 501 is specifically configured to determine the transport layer occupied by the UCI and / or the transport layer to be mapped by the UCI based on the bit length of the UCI and / or the information type included in the UCI, wherein the transport layer is the transport layer corresponding to the plurality of CWs.

[0141] Figure 6 This is a schematic diagram of another communication device provided in an embodiment of this application, used to implement the above. Figure 3 or Figure 4 The communication device 600 can be a terminal device or a device for a terminal device. The device for the terminal device can be a chip system or a chip within the terminal device. The chip system can consist of chips or may include chips and other discrete components.

[0142] The communication device 600 includes at least one processor 620 for implementing the resource mapping function of the terminal device in the method provided in this application embodiment. The device 600 may also include a communication interface 610 for implementing the send and receive operations of the terminal device in the method provided in this application embodiment. In this application embodiment, the processor 620 may be a Central Processing Unit (CPU), or it may be other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or any conventional processor. In this application embodiment, the communication interface 610 may be a transceiver, circuit, bus, module, or other type of communication interface for communicating with other devices via a transmission medium. For example, the communication interface 610 allows the device in device 600 to communicate with other devices. The processor 620 uses the communication interface 610 to send and receive data and to implement the above method embodiments. Figure 2 The method described.

[0143] The communication device 600 may further include at least one memory 630 for storing program instructions and / or data. The memory 630 is coupled to the processor 620. The coupling in this embodiment is an indirect coupling or communication connection between devices, units, or modules, and may be electrical, mechanical, or other forms, for information exchange between devices, units, or modules. The processor 620 may operate in conjunction with the memory 630. The processor 620 may execute program instructions stored in the memory 630. At least one of the at least one memory may be included in the processor.

[0144] When the communication device 600 is powered on, the processor 620 can read the software program in the memory 630, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be transmitted wirelessly, the processor 620 performs baseband processing on the data to be transmitted and outputs the baseband signal to the radio frequency circuit (not shown in the figure). The radio frequency circuit processes the baseband signal and transmits the radio frequency signal outward in the form of electromagnetic waves through the antenna. When data is sent to the device 600, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 620. The processor 620 converts the baseband signal into data and processes the data.

[0145] In another implementation, the radio frequency circuit and antenna can be set up independently of the processor 620 that performs baseband processing. For example, in a distributed scenario, the radio frequency circuit and antenna can be arranged in a remote manner, independent of the communication device.

[0146] This application embodiment does not limit the specific connection medium between the communication interface 610, processor 620, and memory 630. This application embodiment... Figure 6 The memory 630, processor 620, and communication interface 610 are connected via a bus 640. Figure 6 The connections between other components are shown in bold and are for illustrative purposes only, not as limiting information. The bus can be divided into address bus, data bus, control bus, etc. For ease of illustration, Figure 6 The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.

[0147] When the communication device 600 is specifically used in a terminal device, such as when the communication device 600 is specifically a chip or chip system, the communication interface 610 can output or receive baseband signals. When the communication device 600 is specifically a terminal device, the communication interface 610 can output or receive radio frequency signals.
