[0050] 2) Method for determining UCI resources when UCI and PUSCH are multiplexed and transmitted in the NR system

[0051] In the NR system, uplink PUSCH transmission supports not only DFT-S-OFDM waveforms but also CP-OFDM waveforms. However, the mapping rules of uplink control information (UCI) on the physical uplink shared channel (PUSCH) are the same for both waveforms.

[0052] The types of UCI information carried on PUSCH include one or more of the following: Hybrid Automatic Repeat request-ACKnowledgement (HARQ-ACK), Channel State Information (CSI) Part 1, CSI Part 2, and Configured Grant-UCI (CG-UCI). When the UCI information carried on PUSCH includes both HARQ-ACK and CG-UCI, HARQ-ACK and CG-UCI are jointly encoded. When the UCI information carried on PUSCH does not include both HARQ-ACK and CG-UCI, the three parts of HARQ-ACK or CG-UCI, CSI Part 1, and CSI Part 2 are independently encoded. The purpose is to protect the transmission of UCI information with higher reliability requirements.

[0053] Regarding the channel coding type used, UCI is transmitted on the PUSCH using the same scheme as that used for UCI transmission on the PUCCH. That is, when the number of UCI bits is greater than or equal to 12, UCI is encoded by Polar code; when the number of UCI bits is less than or equal to 11, UCI is encoded by channel coding of small block lengths.

[0054] Because the length of the sequence after channel coding cannot meet the requirements of the total number of resource elements (REs) actually mapped, rate matching is required to adaptively adjust the channel-coded bit sequence so that it can be mapped onto all allocated REs. This process is achieved through rate matching. Rate matching for UCI transmission on the PUSCH is specifically divided into two cases: when the PUSCH carries uplink data and when the PUSCH does not carry uplink data.

[0055] When the PUSCH carries uplink data, the number of REs occupied by each independently encoded UCI information is determined by the ratio of the total number of bits of this UCI information (including the number of Cyclic Redundancy Check (CRC) codes) to the total number of bits of uplink data (including the number of CRCs). This determines the proportion of the total RE resources occupied by this UCI information in the total RE resources of the PUSCH. At the same time, considering that the transmission reliability requirement of UCI information is higher than the reliability requirement of data transmission, a code rate compensation factor (β) is introduced for the UCI information when calculating this ratio. In addition, to ensure the transmission of uplink data, the UCI information may not occupy all RE resources. The standard implements this by introducing a parameter (α) configured by high-level signaling. This parameter is used to limit the upper limit of the number of REs occupied by each type of UCI information.

[0056] PUSCH introduces factors such as high-order modulation, resulting in lower transmission reliability of PUSCH than that of PUCCH. Therefore, in order to ensure the reliability of UCI transmission on PUSCH, different rate compensation factors (β) are defined for different UCI information. That is, more RE resources will be allocated to UCI with the same bit rate. This method improves the transmission reliability of UCI by reducing the UCI code rate. If the DCI scheduling PUSCH includes a rate compensation factor indicator field, the rate compensation factor is semi-statically configured for the UE through high-level signaling, and then dynamically indicated to the UE through the DCI scheduling PUSCH. If the DCI scheduling PUSCH does not include a rate compensation factor indicator field, the UE uses the rate compensation factors configured by the high-level layer.

[0057] When the PUSCH does not carry uplink data, the data information bit is 0, so the calculation method for the case where uplink data is carried cannot be directly applied. However, since there is no need to indicate the modulation order and code rate of the data transmission, the MCS (Modulation and Coding Scheme) field in the DCI signaling that schedules the PUSCH is considered to indicate a reference code rate and modulation order. Therefore, when the PUSCH does not carry uplink data, the number of RE resources occupied by each part of the independently encoded UCI information is directly calculated based on the total number of information bits of this part of the UCI information, the reference code rate, the modulation order, and the code rate compensation factor.

[0058] It can be understood that, in the case where the PUSCH does not carry uplink data, the type of UCI information carried on the PUSCH includes one or more of the following: HARQ-ACK, CSI Part 1, and CSI Part 2.

[0059] 3) PUSCH transmission in NTN system

[0060] In NTN systems, repeated transmission of the PUSCH is often used to improve uplink coverage in a cell. For example, a PUSCH is repeated N times in the time domain. Since a PUSCH needs to be repeated N times, the uplink resources occupied are N times that of a non-repeated PUSCH, resulting in a reduction in the system's uplink capacity. Therefore, in this scenario, to improve the uplink capacity of the NTN system, the PUSCH can be transmitted using orthogonal codes (also known as orthogonal cover codes, OCC) spread spectrum.

[0061] FIG3 is an example diagram of using OCC to transmit PUSCH to improve uplink capacity involved in an embodiment of the present application, which gives an example of improving uplink capacity. In the case where OCC is not used, assuming that UE1 needs to transmit TB (Transport Block) 1 four times in order to meet the uplink coverage requirement, the network device needs to allocate four resources for the TB1 of UE1 for transmission, that is, the four resources serve one terminal device. In the case of using OCC, on the four resources allocated by the network device, UE1 can use one OCC (for example, OCC1) to transmit TB1, UE2 can use one OCC (for example, OCC2) to transmit TB2, UE3 can use one OCC (for example, OCC3) to transmit TB3, and UE4 can use one OCC (for example, OCC4) to transmit TB4, that is, the four resources can serve four terminal devices, and the uplink transmissions of different terminal devices can be guaranteed to be orthogonal by different OCCs, thereby achieving the purpose of improving uplink capacity while ensuring the uplink coverage of the terminal devices.

[0062] In a communication system (such as NTN), when a terminal device uses OCC for PUSCH transmission, if the terminal device needs to multiplex UCI and PUSCH for transmission, to ensure the orthogonality of the PUSCH transmitted by the terminal device, UCI should also be transmitted using OCC. Therefore, when UCI is also transmitted using OCC, how to determine the number of RE resources occupied by UCI is an unresolved issue.

[0063] Taking the OCC spreading unit with a symbol or time slot size of 1 PUSCH and an OCC set of {{+1, +1, +1, +1}, {+1, -1, +1, -1}, {+1, +1, -1, -1}, {+1, -1, -1, +1}} as an example, an example is given of using different OCCs for different terminal devices to perform PUSCH transmission on the same time domain and frequency domain resources.

[0064] Figure 4 is an example diagram of time-domain OCC spread spectrum involved in an embodiment of the present application; as shown in Figure 4, UE1, UE2, UE3, and UE4 are allocated the same time-domain and frequency-domain resources for PUSCH transmission. For each of UE1, UE2, UE3, and UE4, the PUSCH includes 12 data symbols, wherein the kth data symbol, the k+3th data symbol, the k+6th data symbol, and the k+9th data symbol in the PUSCH carry the same information, and k is 0, 1, and 2. In other words, the 0th, 3rd, 6th, and 9th symbols in the PUSCH are data symbols for repeated transmission, the 1st, 4th, 7th, and 10th symbols are data symbols for repeated transmission, and the 2nd, 5th, 8th, and 11th symbols are data symbols for repeated transmission.

[0065] The OCC used by UE1 is {+1, +1, +1, +1}, then all data symbols in the PUSCH transmitted by UE1 are scrambled with the OCC factor {+1}; the OCC used by UE2 is {+1, -1, +1, -1}, then the 0th, 1st, and 2nd data symbols in the PUSCH transmitted by UE2 are scrambled with the OCC factor {+1}, the 3rd, 4th, and 5th data symbols are scrambled with the OCC factor {-1}, the 6th, 7th, and 8th data symbols are scrambled with the OCC factor {+1}, and the 9th, 10th, and 11th data symbols are scrambled with the OCC factor {-1}; the OCC used by UE3 is {+1, +1, -1, -1}, then the 0th data symbol in the PUSCH transmitted by UE3 is scrambled with the OCC factor {+1}. The 0th, 1st, and 2nd data symbols use OCC factor {+1} scrambling, the 3rd, 4th, and 5th data symbols use OCC factor {+1} scrambling, the 6th, 7th, and 8th data symbols use OCC factor {-1} scrambling, and the 9th, 10th, and 11th data symbols use OCC factor {-1} scrambling; the OCC used by UE4 is {+1, -1, -1, +1}, then the 0th, 1st, and 2nd data symbols in the PUSCH transmitted by UE4 use OCC factor {+1} scrambling, the 3rd, 4th, and 5th data symbols use OCC factor {-1} scrambling, the 6th, 7th, and 8th data symbols use OCC factor {-1} scrambling, and the 9th, 10th, and 11th data symbols use OCC factor {+1} scrambling.

[0066] When a UE needs to multiplex UCI transmission on the PUSCH, if the PUSCH uses OCC transmission, then the UCI must also be transmitted using OCC to ensure that the orthogonality of PUSCH transmissions from different UEs is not destroyed. In this case, the UE needs to enhance the method of determining UCI resources.

[0067] In this regard, the solution shown in the subsequent embodiments of the present application discloses a solution for determining the number of resources occupied by UCI when multiplexing UCI and PUSCH, thereby enhancing the multiplexing transmission of UCI and PUSCH to improve the performance of the terminal device when using OCC for PUSCH transmission.

[0068] Please refer to Figure 5, which shows a flowchart of a method for determining the number of resources provided by an embodiment of the present application. This method can be performed by a terminal device, wherein the terminal device can be a terminal device in the aforementioned network architecture or a terminal device in other network architectures, and this application is not limited to this. The method can include at least some of the following steps:

[0069] Step 510: Determine a first time-frequency resource, where the first time-frequency resource is used to transmit a first physical uplink shared channel PUSCH. The first PUSCH is used to carry target uplink control information UCI. The first PUSCH corresponds to an orthogonal cover code (OCC) spread spectrum transmission method.

[0070] Step 520: Determine the amount of resources occupied by the target UCI in the first time-frequency resource.

[0071] Optionally, the terminal device may transmit the target UCI on the first time domain resources according to the amount of resources occupied by the target UCI in the first time-frequency resources.

[0072] To sum up, the scheme shown in the embodiment of the present application is that when the terminal device determines that the first time-frequency resource is used to transmit the first physical uplink shared channel PUSCH, the first PUSCH is used to carry the target uplink control information UCI, and the first PUSCH corresponds to the orthogonal mask code OCC spread spectrum transmission mode, the terminal device can determine the number of resources occupied by the target UCI in the first time-frequency resource; the above scheme provides a method for determining the number of resources that supports OCC spread spectrum transmission of UCI when multiplexing UCI transmission on PUSCH, thereby enhancing the multiplexing transmission of UCI and PUSCH, and further improving the performance of the terminal device when using OCC to multiplex UCI and PUSCH for transmission.

[0073] Please refer to Figure 6, which shows a flowchart of a method for determining the number of resources provided by one embodiment of the present application. The method can be performed by a network device, wherein the network device can be a network device in the aforementioned network architecture or a network device in another network architecture, and the present application is not limited to this. The method can include at least some of the following steps:

[0074] Step 610: Determine a first time-frequency resource, where the first time-frequency resource is used by the terminal device to transmit a first physical uplink shared channel PUSCH. The first PUSCH is used to carry target uplink control information UCI, wherein the first PUSCH corresponds to an orthogonal cover code OCC spread spectrum transmission method.

[0075] Step 620: Determine the amount of resources occupied by the target UCI in the first time-frequency resource.

[0076] Optionally, the network device may receive the target UCI transmitted by the terminal device on the first time domain resource according to the amount of resources occupied by the target UCI in the first time-frequency resource.

[0077] To sum up, the scheme shown in the embodiment of the present application is that the network device can determine the number of resources occupied by the target UCI in the first time-frequency resource when determining that the first time-frequency resource is used to transmit the first physical uplink shared channel PUSCH, the first PUSCH is used to carry the target uplink control information UCI, and the first PUSCH corresponds to the orthogonal mask code OCC spread spectrum transmission mode; the above scheme provides a method for determining the number of resources that supports OCC spread spectrum transmission of UCI when multiplexing UCI transmission on PUSCH, thereby enhancing the multiplexing transmission of UCI and PUSCH, and further improving the performance of the terminal device when using OCC to multiplex UCI and PUSCH for transmission.

[0078] Please refer to Figure 7, which shows a flowchart of a method for determining the number of resources provided by an embodiment of the present application. The method can be interactively executed by a terminal device and a network device; wherein the terminal device can be a terminal device in the aforementioned network architecture or a terminal device in another network architecture; the network device can be a network device in the aforementioned network architecture or a network device in another network architecture; this application does not limit this.

[0079] Step 710: The terminal device and the network device respectively determine a first time-frequency resource, the first time-frequency resource is used by the terminal device to transmit a first physical uplink shared channel PUSCH, the first PUSCH is used to carry target uplink control information UCI, wherein the first PUSCH corresponds to an orthogonal cover code OCC spread spectrum transmission method.

[0080] Step 720: The terminal device and the network device respectively determine the amount of resources occupied by the target UCI in the first time-frequency resource.

[0081] In an embodiment of the present application, the terminal device transmits the first physical uplink shared channel PUSCH through the first time-frequency resource. The first PUSCH is used to carry the target uplink control information UCI. The first PUSCH corresponds to the orthogonal mask OCC spread spectrum transmission mode. The OCC length of the OCC spread spectrum transmission corresponding to the first PUSCH is N, and N is a positive integer; at this time, the terminal device can determine the number of resources occupied by the target UCI in the first time-frequency resource according to the OCC length N.

[0082] In some embodiments, the method further includes: the network device sending first configuration information to the terminal device, the first configuration information being used to determine a mode in which the first PUSCH corresponds to OCC spread spectrum transmission. Accordingly, the terminal device determines, based on the first configuration information sent by the network device, the mode in which the first PUSCH corresponds to OCC spread spectrum transmission.

[0083] In some embodiments, the first PUSCH corresponds to an orthogonal cover code (OCC) spread spectrum transmission mode, including: a terminal device determining, based on first configuration information sent by a network device, the mode in which the first PUSCH corresponds to the OCC spread spectrum transmission mode. For example, the first configuration information is used to configure the PUSCH to be transmitted using the OCC spread spectrum transmission mode, and when the terminal device determines to transmit UCI via the first PUSCH, the uplink data and / or UCI carried on the first PUSCH corresponds to the OCC spread spectrum transmission mode.

[0159] In the embodiment of the present application, P represents the total number of REs occupied by other UCIs.

In other words, in this case, the resources occupied by the joint encoding of HARQ-ACK and CG-UCI are determined first, followed by the resources occupied by CSI Part 1 encoding, and finally the resources occupied by CSI Part 2 encoding. When the UCI information carried on the PUSCH does not include both HARQ-ACK and CG-UCI, HARQ-ACK or CG-UCI has the highest priority, followed by CSI Part 1, and then CSI Part 2. In other words, in this case, the resources occupied by the encoding of HARQ-ACK or CG-UCI are determined first, followed by the resources occupied by CSI Part 1 encoding, and finally the resources occupied by CSI Part 2 encoding.

When the number of HARQ-ACK information bits is less than or equal to 2 bits (i.e., the number of HARQ-ACK information bits is 0 or 1), the number of REs occupied by HARQ-ACK is always calculated based on the number of HARQ-ACK information bits being 2.

When the CG-UCI encoding uses a short code, the number of CRC bits is 0.

[0170] In the embodiment of the present application, Q CG-UCI Indicates the number of REs occupied after CG-UCI encoding.

[0171] As another example, when the target UCI includes HARQ-ACK and CG-UCI, HARQ-ACK and CG-UCI are jointly encoded, and the number of REs occupied by HARQ-ACK and CG-UCI (wherein the joint encoding of HARQ-ACK and CG-UCI corresponds to the above-mentioned first UCI) can be calculated according to the following formula. At this time, HARQ-ACK and CG-UCI have the highest priority, and no other UCI occupies resources, so P is 0.

[0172] In the embodiment of the present application, U HARQ-ACK,CG-UCI Represents the total number of information bits obtained by HARQ-ACK and CG-UCI after CRC bits are added (i.e., the sum of the number of information bits of HARQ-ACK and CG-UCI and the sum of the number of CRC bits corresponding to the HARQ-ACK and CG-UCI encoding). When HARQ-ACK and CG-UCI are jointly encoded using a short code, the number of CRC bits is 0.

[0173] In the embodiment of the present application, Q HARQ-ACK,CG-UCI Indicates the number of REs occupied after HARQ-ACK and CG-UCI are jointly encoded.

[0178] In the embodiment of the present application, Q CSI-1 Indicates the number of REs occupied after CSI Part 1 encoding.

[0179] As another example, when the target UCI includes CSI Part 2, the number of REs occupied by CSI Part 2 (corresponding to the first UCI mentioned above) can be calculated according to the following formula.

[0180] In the embodiment of the present application, U CSI-2 Indicates the total number of information bits obtained after the CRC bits are added to CSI Part 2 (i.e., the sum of the number of information bits in CSI Part 2 and the number of CRC bits corresponding to the CSI Part 2 encoding).

[0185] As an example, when the target UCI does not include CG-UCI, the number of REs occupied by HARQ-ACK (corresponding to the above-mentioned first UCI) can be calculated according to the following formula. Similarly, when the number of HARQ-ACK information bits is less than or equal to 2 bits (that is, the number of HARQ-ACK information bits is 0 or 1), the number of REs occupied by HARQ-ACK is always calculated based on the number of HARQ-ACK information bits being equal to 2.

[0221] The first PUSCH corresponds to a method of performing OCC spread spectrum transmission among multiple PUSCHs.

[0222] The above formulas (7) to (9) can be applied to the case where the first PUSCH corresponds to the OCC spread spectrum transmission mode within multiple PUSCHs, such as the above case 4.

[0223] The above formula (6) can be applied to the case where the first PUSCH corresponds to the OCC spread spectrum transmission mode within one or more PUSCHs, such as the above case 3 and case 4.

[0224] In the above embodiment, the OCC spread spectrum transmission mode corresponding to the first PUSCH is the inter-time slot OCC spread spectrum mode. When there is no TB carrying uplink data on the first PUSCH, as an example, the number of REs occupied by HARQ-ACK can be determined according to the above formula (7).

[0225] As another example, the number of REs occupied by CSI Part 1 can be calculated according to the following formula:

[0226] When CSI Part 2 is to be transmitted on the PUSCH, the number of REs occupied by CSI Part 1 can be determined according to the above formula (8).

[0227] Otherwise, the number of REs occupied by CSI Part 1 can be determined according to the above formula (9).

[0228] As another example, the number of REs occupied by CSI Part 2 can be determined according to the above formula (6).

[0229] In cases 3 and 4 above:

[0230] In some embodiments, when the first PUSCH does not carry a TB for uplink data, even if the first PUSCH corresponds to OCC spread spectrum transmission, the target UCI does not use OCC spread spectrum transmission. In this case, the influence of the OCC length N does not need to be considered when determining the number of UCI resources.

[0231] In some embodiments, the target UCI includes HARQ-ACK and CSI Part 1, and determining the amount of resources occupied by the target UCI in the first time-frequency resource includes:

[0232] The number of resource units RE occupied by HARQ-ACK in the first time-frequency resource is determined according to the following formula:

[0233] Among them, Q HARQ-ACK Indicates the number of REs occupied in the first time-frequency resource after HARQ-ACK encoding; U HARQ-ACK Indicates the total number of information bits in HARQ-ACK after CRC bits are added; represents the code rate compensation factor of HARQ-ACK; R represents the coding rate indicated by the network device; QM represents the modulation order indicated by the network device; M represents the total number of REs that can be used for UCI transmission in the first time-frequency resource; α represents the quantization factor; Indicates rounding up;

[0234] When the target UCI includes CSI Part 2, the number of REs occupied by CSI Part 1 in the first time-frequency resource is determined according to the following formula:

[0235] When the target UCI does not include CSI Part 2, the number of REs occupied by CSI Part 1 in the first time-frequency resource is determined according to the following formula: CSI-1 =MQ HARQ-ACK (12)

[0236] Among them, Q CSI-1 Indicates the number of REs occupied in the first time-frequency resource after CSI Part 1 encoding; U CSI-1 Indicates the total number of information bits in CSI Part 1 after CRC bits are added; Indicates the rate compensation factor for CSI Part 1;

[0237] When the target UCI includes CSI Part 2, the number of REs occupied by CSI Part 2 in the first time-frequency resource is determined according to the following formula: CSI-2 =MQ HARQ-ACK -Q CSI-1

[0238] Among them, Q CSI-2 Indicates the number of REs occupied in the first time-frequency resource after CSI Part 2 encoding.

[0239] For example, in some embodiments, when the OCC spread spectrum transmission mode corresponding to the first PUSCH is the OCC spread spectrum mode between time slots, and there is no TB carrying uplink data on the first PUSCH, the terminal device does not consider the influence of the OCC length N when determining the number of resources occupied by the target UCI in the first time-frequency resource.

[0240] Specifically, the number of REs occupied by HARQ-ACK can be calculated and determined according to the above formula (10):

[0241] When CSI Part 2 is to be transmitted on the PUSCH, the number of REs occupied by CSI Part 1 can be calculated and determined according to the above formula (11).

[0242] Otherwise, the number of REs occupied by CSI Part 1 can be calculated and determined according to the above formula (12).

[0243] The number of REs occupied by CSI Part 2 can be calculated and determined according to the above formula (6).

[0244] Step 730: The terminal device transmits the target UCI on the first time domain resource according to the amount of resources occupied by the target UCI in the first time-frequency resource; correspondingly, the network device receives the target UCI on the first time domain resource according to the amount of resources occupied by the target UCI in the first time-frequency resource.

[0245] Among them, after the terminal device determines the number of resources occupied by the target UCI in the first time-frequency resources, it can multiplex the UCI PUSCH for transmission on the first time-frequency resources according to the number of resources occupied by the target UCI in the first time-frequency resources. Accordingly, the network device receives the target UCI transmitted by the terminal device on the first time-frequency resources; wherein the above-mentioned PUSCH can be transmitted through the OCC spread spectrum method.

[0246] In the NTN system, in order to improve the uplink coverage of the cell and the uplink capacity of the system, when the terminal device uses OCC transmission for PUSCH, when the terminal device needs to multiplex UCI and PUSCH for transmission, in order to ensure the orthogonality of the PUSCH transmitted by the terminal device, UCI should also be transmitted using OCC. In this embodiment of the present application, the OCC length can be used to determine the number of RE resources occupied by UCI, which can ensure the reliability of UCI transmission and can also ensure that the resources allocated for UCI can use OCC transmission to transmit UCI (for example, the UCI resources are an integer multiple of the OCC length N).
