Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to information transmission methods, information reception methods, and communication devices in wireless communication systems. Background Technology

[0002] 5G communication systems are designed to support higher system performance, supporting a variety of service types, different deployment scenarios, and a wider spectrum range. These service types include enhanced mobile broadband (eMBB), massive machine-type communication (mMTC), ultra-reliable and low-latency communications (URLLC), multimedia broadcast multicast service (MBMS), and location services. Different deployment scenarios include indoor hotspots, dense urban areas, suburbs, urban macro coverage, and high-speed rail applications. The wider spectrum range means that 5G will support a spectrum range of up to 100 GHz, including both low-frequency frequencies below 6 GHz and high-frequency frequencies above 6 GHz up to 100 GHz.

[0003] When uplink control information (UCI) from different priority services needs to be multiplexed on the same physical uplink shared channel (PUSCH) using independent encoding, decoding errors may occur when resource mapping is performed sequentially for different priority UCIs. For example, if a high-priority UCI is mapped incorrectly, the mapping position of low-priority UCIs will also be incorrect, leading to decoding errors by network devices. Therefore, improving the decoding accuracy of UCI information is an urgent problem to be solved. Summary of the Invention

[0004] This application provides an information sending method, an information receiving method, and a communication device, which can improve the decoding accuracy of UCI information.

[0005] In a first aspect, an information transmission method is provided, comprising: determining the starting position and upper limit of the number of resource elements (RFIs) of a first uplink control information (UCI) mapped on an uplink physical shared channel (PUSCH); determining the starting position of a second uplink control information (UCI) mapped on the PUSCH based on the starting position and upper limit of the number of RFIs of the first UCI, wherein the priority of the first UCI is higher than the priority of the second UCI; determining the actual number of RFIs of the first UCI and the actual number of RFIs of the second UCI; mapping the first UCI on the PUSCH based on the starting position and the actual number of RFIs of the first UCI; mapping the second UCI on the PUSCH based on the starting position and the actual number of RFIs of the second UCI; and transmitting the PUSCH.

[0006] In the technical solution of this application embodiment, the starting position of the second UCI mapping on the PUSCH is determined according to the starting position of the first UCI mapping on the PUSCH and the upper limit of the number of resource units. Since the starting position of the second UCI mapping on the PUSCH is not limited by whether the first UCI has a payload size error, this mapping method can ensure that the position of the second UCI mapping on the PUSCH is correct when the first UCI has a payload size error, avoiding the second UCI mapping position from being associated with errors, thereby improving the decoding accuracy of UCI information.

[0007] In conjunction with the first aspect, in some implementations of the first aspect, determining the upper limit of the number of the first UCI resource units includes: determining the upper limit of the number of the first UCI resource units based on configuration information sent by the network device, wherein the configuration information includes a ratio for indicating the upper limit of the number of resource units of the first UCI, and determining the upper limit of the number of the first UCI resource units based on the ratio of the upper limit of the number of the first UCI resource units and the total number of resource units available for UCI transmission on the PUSCH.

[0008] In some possible implementations, this configuration information may also include other instruction information.

This implementation is independent of the starting position of the first UCI mapping on the PUSCH and the upper limit of the number of resource units.

[0012] In the technical solution of this application embodiment, the starting position of the second UCI mapped on the PUSCH is not affected by whether the first UCI has a load size error. Therefore, the second UCI will not have a cascading error due to the first UCI having a load size error, thereby improving the decoding accuracy of UCI information.

[0123] The technical solutions of this application will now be described with reference to the accompanying drawings. It should be understood that the described embodiments are only some, not all, of the embodiments described in this application.

[0124] The technical solutions of this application embodiment can be applied to various communication systems, such as: Global System for Mobile Communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Frequency Division Duplex (FDD) system, LTE Time Division Duplex (TDD) system, Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) system, 5th Generation (5G) system or New Radio (NR) system, or future evolution networks, etc.

[0125] To facilitate understanding of the embodiments of this application, firstly, in conjunction with Figure 1 A detailed description of the communication system applicable to the methods provided in the embodiments of this application is provided. Figure 1 The figure shows a schematic diagram of a communication system applicable to the methods provided in the embodiments of this application. As shown, the communication system may include at least one network device, such as... Figure 1 The 5G system shown includes a base station (gNB); the communication system may also include at least one terminal device, such as... Figure 1 The user equipment (UE) shown is 1 to UE6. Network devices and terminal devices can communicate via a wireless link. For example, a network device can send configuration information to a terminal device, and the terminal device can send uplink data to the network device based on this configuration information; similarly, a network device can send downlink data to a terminal device. Therefore, Figure 1 The gNB and UE in the system can form a communication system.

[0126] The terminal devices in this communication system, such as UE 4 to UE 6, can also constitute a communication system. For example, UE 4 can control UE 5 and UE 6 to execute corresponding instructions. This application does not limit this.

[0127] It should be understood that the network equipment in this communication system can be any device with wireless transceiver capabilities. The network equipment includes, but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), access point (AP), wireless relay node, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP) in a wireless fidelity (WiFi) system. It can also be a gNB in ​​a 5G system, such as NR, or a transmission point (TRP or TP), one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB or transmission point, such as a baseband unit (BBU) or a distributed unit (DU).

[0128] In some deployments, a gNB may include a centralized unit (CU) and a distribution unit (DU). A gNB may also include a radio unit (RU). The CU implements some of the gNB's functions, and the DU implements others. For example, the CU implements radio resource control (RRC) and packet data convergence protocol (PDCP) layer functions, while the DU implements radio link control (RLC), media access control (MAC), and physical (PHY) layer functions. Since RRC layer information ultimately becomes PHY layer information, or is derived from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling, can be considered to be sent by the DU, or by the DU+CU. It is understood that network devices can be CU nodes, DU nodes, or devices including both CU and DU nodes. Furthermore, the CU can be classified as a network device in the radio access network (RAN) or as a network device in the core network (CN), and this application does not limit this.

[0129] It should also be understood that the terminal equipment in this wireless communication system can also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication equipment, user agent, or user device. In the embodiments of this application, the terminal equipment can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal device, augmented reality (AR) terminal device, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. The embodiments of this application do not limit the application scenarios.

[0130] It's understandable. Figure 1This is a simplified illustration for ease of understanding only. The communication system may also include other network devices or other terminal devices. Figure 1 It was not drawn in the middle.

[0131] A key feature of 5G communication systems compared to 4G is the addition of support for Ultra-Reliable Low-Latency Communications (URLLC). URLLC encompasses a wide range of services, with typical use cases including industrial control, industrial process automation, human-machine interaction, and telemedicine.

[0132] Due to its low latency and high reliability, URLLC is a high-priority service compared to other services in 5G communication. The low latency and high reliability of URLLC services are defined by the performance metrics of the 3GPP RAN and RAN 1 working groups.

[0133] Latency refers to the transmission time required for a user application layer data packet to travel from the SDU (Service Data Unit) at the sending end of the wireless protocol stack layer 2 / 3 to the SDU at the receiving end of the wireless protocol stack layer 2 / 3. When neither the network device nor the terminal device is in a discontinuous reception state, the user plane latency requirement for URLLC services is 0.5ms for both uplink and downlink. This 0.5ms performance requirement refers to the average latency of the data packet.

[0134] Reliability refers to the probability that the sending end will successfully transmit X bits of data correctly to the receiving end within a certain time (L seconds). This time is still defined as the time required for a user application layer data packet to travel from the sending end's wireless protocol stack layer 2 / 3 SDU to the receiving end's wireless protocol stack layer 2 / 3 SDU. For URLLC services, a typical requirement is to achieve 99.999% reliability in transmitting 32 bytes of data within 1 ms. Specific URLLC services have different requirements; for example, some extremely demanding industrial control systems require a 99.9999999% transmission success probability with an end-to-end latency of less than 0.25 ms.

[0135] Because URLLC services require high reliability, Hybrid Automatic Repeat Request (HARQ) is an efficient transmission mechanism that can greatly improve the reliability of downlink data transmission. The UE sends HARQ feedback information (HARQ-ACK) based on the actual situation. The network device only needs to retransmit when the UE sends a HARQ negative acknowledgment message, thus reducing the overall resource consumption of data transmission.

[0136] HARQ feedback information is a type of uplink control information (UCI). UCI also includes scheduling requests (SR). Channel state information (CSI) consists of CSI part 1 and CSI part 2.

[0137] The mapping rules for multiplexing different types of UCI information and uplink data information of the same priority on the physical uplink shared channel (PUSCH) in the existing technology are as follows, which will be combined with the following... Figure 2 The multiplexing of UCI and uplink data with the same priority on the PUSCH is explained, where, Figure 2 This is a schematic diagram illustrating the mapping rule of the same priority UCI and uplink data multiplexing on the PUSCH in a prior art of this application. Figure 3 This application presents another prior art diagram illustrating the mapping rules for the same priority UCI and uplink data multiplexing on the PUSCH.

[0138] Taking different types of UCI with the same priority, including HARQ feedback information, CSI part1 and CSI part2, as an example, the mapping order of UCI with the same priority and uplink data information multiplexed on PUSCH is HARQ feedback information, CSI part1, CSI part2 and uplink data information.

[0139] Figure 2 The HARQ feedback information in (a), (b), (c), and (d) is mapped as follows: when the HARQ feedback information is greater than 2 bits, it is mapped sequentially starting from the first available symbol after the DMRS symbol, according to its actual size. If the HARQ feedback information can fill the entire current symbol, it fills the current symbol and then occupies the next symbol. If the HARQ feedback information is insufficient to fill the entire current symbol, it will be evenly distributed across the frequency domain resources within the current symbol.

[0140] S201, Mapping HARQ feedback information in UCI information. HARQ feedback information is mapped starting from the first available symbol after the DMRS symbol, such as... Figure 2 (a)

[0141] S202, when the HARQ feedback information is greater than 2 bits, such as Figure 2 (b) CSI part 1 is sequentially mapped starting from the first available symbol resource on the PUSCH, where the first available symbol resource is the resource unit excluding the mapping of DMRS and HARQ feedback information, and the first available symbol resource on the PUSCH.

[0142] S203, when the HARQ feedback information is greater than 2 bits, such as Figure 2 (c) starts with the first available symbol resource on the PUSCH and sequentially maps CSI part 2, where the first available symbol resource is the resource unit that excludes DMRS, HARQ feedback information and CSI part 1 mapping, and is the first available symbol resource on the PUSCH.

[0143] S204, when the HARQ feedback information is greater than 2 bits, such as Figure 2 (d) The uplink data is sequentially mapped starting from the first available symbol resource on the PUSCH, where the first available symbol resource is the resource excluding DMRS, HARQ feedback information, CSI part 1 and CSI part 2 mappings, and is the first available symbol resource on the PUSCH.

[0144] Figure 3 The HARQ feedback information in (a), (b), (c), (d), and (e) is mapped such that when the HARQ feedback information is any of 0, 1, or 2 bits, PUSCH resources are reserved starting from the first UCI available symbol after the DMRS symbol in the PUSCH, according to the 2-bit HARQ feedback information, becoming a reserved area. It should be understood that since the number of bits represented by each symbol in the resource block depends on the selected modulation order, the number of UCI and uplink data mapping resource units in the diagram is only for illustrative purposes.

[0145] S301, the number of resource units that need to be mapped for the HARQ feedback information in the reserved UCI information forms the resource reservation area for the HARQ feedback information. This resource reservation area starts from the first available symbol after the DMRS symbol, such as... Figure 3 As shown in (a).

[0146] S302, mapping CSI part 1 in UCI information, when the HARQ feedback information is any one of 0, 1, or 2 bits, such as Figure 3 (b) Starting from the first available symbol resource on the PUSCH, CSI part1 is mapped sequentially, bypassing the reserved area for HARQ feedback information, to ensure that CSI part1 does not conflict with HARQ feedback information. The first available symbol resource is the resource unit excluding the reserved areas for DMRS and HARQ feedback information, and is the first available symbol resource on the PUSCH.

[0147] S303, mapping CSI part 2 in UCI information, when the HARQ feedback information is any of 0, 1, or 2 bits, such as Figure 3(c) starts with the first available symbol resource on the PUSCH and sequentially maps CSI part2. At this time, it is not necessary to bypass the HARQ feedback information reserved area. The first available symbol resource is the resource unit excluding DMRS and CSI part 1, and the first available symbol resource on the PUSCH.

[0148] S304 maps uplink data information. When the HARQ feedback information is any one of 0, 1, or 2 bits, such as... Figure 3 (d) Start mapping uplink data sequentially from the first available symbol resource on the PUSCH. At this time, it is not necessary to bypass the HARQ feedback information reserved area. The first available symbol resource is the resource unit excluding the mapping of DMRS, CSI part 1 and CSI part 2, which is the first available symbol resource on the PUSCH.

[0149] S305, when the HARQ feedback information is any one of 0, 1, or 2 bits, such as Figure 3 (e) Regardless of whether the HARQ feedback information resource reservation area is filled in S303 and S304, the HARQ feedback information resource reservation area will be remapped by the HARQ feedback information. The mapping position starts from the first symbol of the HARQ feedback information resource reservation area to cover the information already mapped in the reservation area.

[0150] Besides reusing uplink data with the same priority but different UCIs on the same PUSCH resource block, it is also possible to reuse UCIs with different priorities on the same PUSCH. In some specific scenarios, when time-domain conflicts occur between services with different priorities, such as when high-priority HARQ feedback information and low-priority HARQ feedback information conflict in the time domain, the reusing of the two can be achieved by jointly encoding them and then uniformly mapping them to resources. Alternatively, the reusing of the two can be achieved by independently encoding them and then sequentially mapping them to resources.

[0151] After the network device sends downlink control information (DCI) for high and low priority services to the terminal device on the physical downlink control channel (PDCCH) or physical downlink shared channel (PDSCH), the terminal device sends UCI information to the network device on the PUSCH to provide feedback on the terminal device's handling of high and low priority services.

[0152] When a terminal device performs blind detection on high-priority DCI information, there may be cases of missed detection. When multiplexing high-priority UCI and low-priority UCI on the same uplink channel resource block, for cases where the two are independently coded and mapped sequentially, the terminal device maps the high-priority UCI information first on the PUSCH, and then maps the low-priority UCI information.

[0153] When a terminal device transmits high-priority and low-priority UCIs on a PUSCH scheduled by downlink control information format 0-1 (UL DCI format 0-1) for uplink transmission, the presence of a downlink assignment index (UL DAI) field indicates the total number of DL DCIs that need to be fed back for HARQ. Even if the terminal device misses a high-priority DCI during blind detection, it will still fill in the missing DL DCI's corresponding UCI information, thus not affecting the position of the low-priority UCI information on the PUSCH and preventing decoding errors in the network device.

[0154] However, when network devices send high and low priority UCIs on the configured grant (CG) PUSCH and the PUSCH used for UL DCI format0-0 scheduling, because there is no UL DAI indication field, when the terminal device misses a blind detection of the high priority DCI information, the UCI information sent by the terminal device will be missing the UCI information corresponding to the missed high priority DCI information. The payload size of this UCI is incorrect, causing the position of the low priority UCI information to be incorrect, resulting in a decoding error for the network device.

[0155] To address the aforementioned problems, this application proposes an information sending method, an information receiving method, and a communication device, which will be described in detail below with reference to the accompanying drawings.

[0156] It should be understood that in the embodiments of this application, the first UCI represents the UCI of a higher priority service and the second UCI represents the UCI of a lower priority service, wherein the priority of the first UCI is higher than that of the second UCI.

[0157] In this application embodiment, there is a relative priority between different services, with the first service having a higher priority than the second service. For example, URLLC service has a higher priority than eMBB service, and this is not limited in the implementation of this application.

[0158] The first UCI and the second UCI transmission combination can be one of the following four types, and this application embodiment does not limit this.

[0159] The first type is where the first UCI is high-priority HARQ feedback information and the second UCI is low-priority HARQ feedback information.

[0160] The second type is where the first UCI is high-priority HARQ feedback information and the second UCI is low-priority UCI information of other types besides HARQ feedback information, such as low-priority CSI information. This is not limited in the embodiments of this application.

[0161] The third type is where the first UCI is high-priority CSI information and the second UCI is low-priority HARQ feedback information.

[0162] The fourth type is where the first UCI is high-priority CSI information and the second UCI is low-priority UCI information of other types besides HARQ feedback information, such as low-priority CSI information. This is not limited in the embodiments of this application.

[0163] Figure 4 This is a schematic flowchart of an information sending method and an information receiving method according to an embodiment of this application.

[0164] S401, the terminal device determines the starting position of the first uplink control information (UCI) mapped on the PUSCH and the upper limit of the number of resource units.

[0165] It should be understood that the upper limit of the number of resource units for the first UCI represents the maximum number of resource units that the first UCI can map on that PUSCH.

[0166] S402, based on the starting position of the first UCI mapped on the PUSCH and the upper limit of the number of resource units, determine the starting position of the second UCI mapped on the PUSCH, wherein the priority of the first UCI is higher than the priority of the second UCI.

[0167] S403, determine the actual number of resource units of the first UCI and the actual number of resource units of the second UCI.

[0168] It should be understood that the first UCI actual resource unit number is the actual resource unit number mapped by the first UCI onto the PUSCH. This actual resource unit number is less than or equal to the upper limit of the first UCI resource unit number. The second UCI actual resource unit number is essentially the same as the first UCI actual resource unit number, and will not be elaborated here.

[0169] It should be understood that the actual number of resource units can be determined according to the rate matching rules. The first UCI and the second UCI have different rate matching rules according to their respective service types.

[0170] S404, map the first UCI on the PUSCH according to the starting position of the first UCI mapping on the PUSCH and the actual number of resource units of the first UCI, and map the second UCI on the PUSCH according to the starting position of the second UCI mapping on the PUSCH and the actual number of resource units of the second UCI.

[0171] S405, the end device sends this PUSCH.

[0172] S406, prior to S401, the network device sends configuration information to the terminal device, which can be used to determine the upper limit of the number of resource units mapped to the PUSCH for the first UCI.

[0173] The following will combine Figure 5 The information sending and receiving methods in the embodiments of this application are described in detail. Figure 5 This is a schematic diagram of a method for reusing UCIs of different priorities on a PUSCH according to an embodiment of this application.

[0174] S501, determine the PUSCH data transmission parameters.

[0175] It should be understood that the PUSCH data transmission parameters are used to determine the starting position of the first UCI and the second UCI mapping on the PUSCH, the upper limit of the number of resource elements, and the actual number of resource elements. Uplink channel data transmission parameters may include the total number of PUSCH resource elements, the position and number of resource elements of the demodulation reference signal (DMRS), the position and number of resource elements of the phase tracking reference signal (PTRS), and the modulation order Q. m And bit rate R, etc.

[0176] The PUSCH can transmit UCI information and uplink data information, or it can transmit UCI information but not uplink data information. This is not a limitation in the embodiments of this application.

[0177] The total number of PUSCH resource units can be configured through high-level configuration information of the network device or dynamically indicated by the network device sending DCI to the terminal device, and is not limited in this embodiment.

[0178] It should be understood that the actual number of resources occupied by the first UCI and the second UCI will be determined using the total number of resource units on the PUSCH that can be used to transmit UCI information. The total number of resource units on the PUSCH that can be used to transmit UCI information can be any number of resource units other than the number of DMRS resource units and the number of PTRS resource units, and is not limited in this embodiment.

[0179] It should be understood that the location of the DMRS information will be used to determine the starting position of the first UCI mapping on the PUSCH. When the first UCI information includes HARQ feedback information, the starting position of the HARQ feedback information on the PUSCH is after the DMRS location.

[0180] For example, such as Figure 6 As shown, Figure 6 This application presents a PUSCH time-frequency resource, where the horizontal axis represents time-domain information, with the smallest horizontal time-domain unit being a symbol, and the vertical axis represents frequency-domain information, with the smallest vertical frequency-domain unit being a subcarrier. A symbol and a subcarrier together constitute the smallest unit of the time-frequency resource, a resource element (RE). As shown in the figure, DMRS is mapped to the third symbol of the PUSCH. Therefore, if the first UCI includes HARQ feedback information, the HARQ feedback information is mapped starting from the fourth symbol.

[0181] It should be understood that UCI information, excluding HARQ feedback information, is mapped starting from the first symbol.

[0182] It should be understood that when the terminal device transmits UCI information on the PUSCH but not uplink data information, the modulation order Q... m The bit rate R will be used to determine the actual number of resources that the UCI information is mapped onto the PUSCH.

[0183] S502, the terminal device determines the upper limit of the number of the first UCI resource units and the upper limit of the number of the second UCI resource units based on the configuration information sent by the network device.

[0184] Corresponding to Figure 4 In step S401, the upper limit of the number of the first UCI resource units is determined.

[0185] It should be understood that network devices send configuration information to terminal devices via radio resource control (RRC) signaling.

[0186] Optionally, the configuration information in this embodiment can be used to indicate the upper limit ratio α of the number of first UCI resource units. HP The upper limit ratio α of the number of second UCI resource units LP The upper limit ratio α of the number of first UCI resource units is directly obtained.

[0187] Optionally, in this embodiment, the configuration information can also be used to indicate the upper limit ratio α of the number of resource units of the first UCI.

[0189] Optionally, in this embodiment, the configuration information can also be used to indicate the ratio α of the sum of the upper limits of the number of the first UCI and the second UCI resource units. HP+LP And the ratio p of the upper limit of the number of first UCI resource units to the sum of the upper limits of the number of first UCI and second UCI resource units.

[0190] Optionally, in this embodiment, the configuration information can also be used to indicate the ratio p of the upper limit of the number of the first UCI resource units to the sum of the upper limits of the number of the first UCI and the second UCI resource units. HP and the upper limit ratio α of the number of resource units indicating the first UCI HP The upper limit ratio α of the number of first UCI resource units is directly obtained.

LP Similarly, the upper limit ratio of the number of the first UCI resource units and the upper limit ratio of the number of the second UCI resource units can be obtained in the same way as described above, which will not be repeated here.

[0193] The first upper limit of the number of UCI resource units is obtained by multiplying the first upper limit ratio of the number of UCI resource units by the total number of resource units available for UCI transmission on the PUSCH; the second upper limit of the number of UCI resource units is obtained by multiplying the second upper limit ratio of the number of UCI resource units by the total number of resource units available for UCI transmission on the PUSCH.

[0194] The upper limit of the number of first UCI resource units can be used to determine the starting position of the second UCI mapping on the PUSCH, and can also be used to control the actual number of first UCI resource units from not exceeding the upper limit of the number of first UCI resource units.

[0195] The upper limit for the number of second UCI resource units is used to control the actual number of second UCI resource units from not exceeding the upper limit for the number of second UCI resource units.

[0196] S503, determine the starting position of the second UCI on the PUSCH.

[0197] Optionally, based on the starting position of the first UCI mapped on the PUSCH and the upper limit of the number of resource units, the starting position of the second UCI on the PUSCH is determined. This step corresponds to... Figure 4 In step S402, the starting position of the PUSCH occupied by the second uplink control information UCI is determined based on the upper limit of the PUSCH occupied by the first UCI, wherein the priority of the first UCI is higher than the priority of the second UCI.

[0198] The starting position of the second UCI mapping on the PUSCH can be the first resource unit of the Nth complete symbol after the upper limit of the number of resource units of the first UCI mapped on the PUSCH, where N is a positive integer greater than or equal to 1.

[0199] For example, Figure 7 This is a schematic diagram of the starting position of a second UCI in the PUSCH in an embodiment of this application. Figure 7(a) Taking UCI information including HARQ feedback information as an example, the starting position of the first UCI mapping on the PUSCH is the symbol after the DMRS information. Based on the upper limit of the resource unit number of the first UCI, the first UCI reserves resources on the PUSCH. These reserved resources are... Figure 7 The values ​​within the dashed box represent the upper limit of the number of resource units for the first UCI, which is reserved for the fourth to sixth symbols in the illustrated time-frequency resource block. Even if the upper limit of the number of resource units reserved by the first UCI on the PUSCH does not fill the sixth symbol, the starting position of the second UCI mapping on the PUSCH can be located at the first resource unit of the seventh symbol.

[0200] Figure 7 (b) Taking UCI information excluding HARQ feedback information as an example, the upper limit of the number of first UCI resource units is Figure 7 Within the dashed box, the first UCI can reserve resources starting from the symbol following the DMRS information, or it can reserve resources starting from the first symbol of the PUSCH based on the upper limit of the number of resource units reserved by the first UCI. Even if the upper limit of the number of resource units reserved by the first UCI on the PUSCH does not fill the fourth symbol, the starting position of the second UCI mapped on the PUSCH can be located at the first resource unit of the fifth symbol.

[0201] Based on the starting position of the first UCI mapping on the PUSCH and the upper limit of the number of resource units, the starting position of the second UCI mapping on the PUSCH is determined. Since the starting position of the second UCI mapping on the PUSCH is not limited by whether the first UCI has a load size error, this mapping method can ensure that the position of the second UCI mapping on the PUSCH is correct when the first UCI has a load size error, thus avoiding the occurrence of cascading errors in the second UCI mapping position.

[0202] Optionally, the second UCI mapping starts at the last symbol on the PUSCH.

[0203] For example, such as Figure 8 As shown, Figure 8 This is a schematic diagram illustrating the starting position of the second UCI in the PUSCH in another embodiment of this application. The starting position of the second UCI mapping on the PUSCH is located at the last symbol of the PUSCH. According to the mapping rule of frequency first and time second, that is, frequency domain mapping first and time domain mapping second, there are two mapping orders for the second UCI in the last symbol of the PUSCH.

[0204] like Figure 8As shown in (a), the second UCI can start mapping from the first resource unit of the last symbol, and map in ascending order of the resource unit frequency domain index. After mapping the last symbol, it can map in descending order of the resource unit time domain index.

[0205] like Figure 8 As shown in (b), the second UCI can also start mapping from the last resource unit of the last symbol, mapping in descending order of the resource unit frequency domain index, and after mapping the last symbol, mapping in descending order of the resource unit time domain index.

[0206] S504 determines the number of the first UCI actual resource units and the second UCI actual resource units based on the configuration information sent by the network device and the rate matching rules.

[0207] It should be understood that the first UCI actual resource unit number is the actual resource unit number mapped by the first UCI onto the PUSCH. This actual resource unit number is less than or equal to the upper limit of the first UCI resource unit number. The second UCI actual resource unit number is essentially the same as the first UCI actual resource unit number, and will not be elaborated here.

[0208] The first UCI actual resource unit number and the second UCI actual resource unit number are obtained through their respective rate matching rules.

[0209] The PUSCH can transmit both UCI information and uplink data information. Alternatively, the PUSCH can transmit UCI information but not uplink data information.

[0210] When both UCI information and uplink data information are transmitted on the PUSCH, the actual number of resources mapped on the PUSCH is calculated according to the following rate matching rules for different types of UCI.

[0211] When the UCI information includes HARQ feedback information and CSI information, the actual number of resource units in the HARQ feedback information is calculated using formula (1), where This indicates rounding up to the nearest integer.

[0212]

[0213] In formula (1), the physical meaning of the first part is the actual number of data bits (the number of bits before encoding) based on the HARQ feedback information. ACK and CRC check bit number L ACK ), rate offset factor The number of resource units after HARQ feedback information encoding is calculated based on the bit rate of the uplink data.

[0214] Among them (O) ACK+L ACK ) / Q' ACK The physical meaning is the UCI bitrate. The physical meaning is the bit rate of the uplink data. This represents the ratio of the uplink data bitrate to the UCI bitrate. The UCI bitrate is lower than the uplink data bitrate, which is beneficial to the reliability of UCI in terms of transmission performance.

[0215] The physical meaning of the second part of formula (1) is to determine the upper limit of the number of resource units for HARQ feedback information based on the upper limit ratio α of the number of resource units mapped by UCI onto PUSCH, where The total number of resource units available for UCI transmission on the PUSCH, where l0 is the symbol index of the first symbol that does not carry the DMRS after the first symbol of the demodulation reference signal DMRS.

[0216] The minimum of the two parts is used as the actual number of resource units Q' in the HARQ feedback information. ACK .

[0217] The CSI information consists of CSI part 1 and CSI part 2. The actual number of resource units in CSI part 1 is calculated by formula (2), and the actual number of resource units in CSI part 2 is calculated by formula (3).

[0218]

[0219]

[0220] When the UCI information only includes HARQ feedback information, the actual number of resource units in the HARQ feedback information is calculated by formula (1).

[0221] When UCI information is transmitted on the PUSCH but not uplink data information, the actual number of resource units is calculated according to the following rate matching rules for different types of UCI.

[0222] When the UCI information includes HARQ feedback information and CSI information, the actual number of resource units in the HARQ feedback information is calculated by formula (4).

[0223]

[0224] Among them, Q m R is the modulation order, and R is the code rate.

[0225] CSI information consists of CSI part 1 and CSI part 2. When UCI information is transmitted on the PUSCH but no uplink data information is transmitted, if CSI part 2 is determined to exist, the actual resource unit number of CSI part 1 is calculated using formula (5), and the actual resource unit number of CSI part 2 is calculated using formula (6). If CSI part 2 is determined not to exist, the actual resource unit number of CSI part 1 is calculated using formula (7).

[0226]

[0227]

[0228]

[0229] In this embodiment of the application, in S502, the terminal device determines that the upper limit of the number of the first UCI resource units can be an upper limit ratio α. HP The upper limit for the number of second UCI resource units can be the upper limit ratio α. LP Therefore, when calculating the actual number of resource units in the first UCI, the appropriate formula can be selected from formulas (1) to (7) above based on the data type transmitted in the current uplink channel. At this time, the upper limit of the UCI ratio α in the formula is α. HP Specifically, when UCI information and data information are transmitted together on the PUSCH, formulas (1) to (4) are used to calculate the first actual UCI resource unit number, where the ratio of data rate to UCI rate is... Replace with the ratio of data bitrate to first UCI bitrate. When UCI information is transmitted on the PUSCH but no uplink data information is transmitted, formulas (5) to (7) are used to calculate the actual number of resource units for the first UCI.

[0230] The actual number of resource units in the second UCI can also be calculated by selecting the appropriate formula from formulas (1) to (7) above, based on the data type transmitted in the current uplink channel. In this case, the upper limit of the UCI ratio α in the formula is α. LP Specifically, when UCI information and data information are transmitted together on the PUSCH, formulas (1) to (4) are used to calculate the actual number of resource units for the second UCI, where the ratio of the data rate to the UCI rate is... Replace with the ratio of data bitrate to the second UCI bitrate. When UCI information is transmitted on the PUSCH but no uplink data information is transmitted, formulas (5) to (7) are used to calculate the actual number of resource units for the second UCI.

[0231] Based on the upper limit of the number of the first UCI resource units and the upper limit of the number of the second UCI resource units obtained directly or indirectly in S502, the actual number of the first UCI resource units and the actual number of the second UCI resource units are determined.

[0232] Taking the first UCI as the high-priority HARQ feedback information and the second UCI as the low-priority HARQ feedback information as an example.

[0233] For example, when configuration information is used to indicate the upper limit ratio α of the number of first UCI resource units. HP The upper limit ratio α of the number of second UCI resource units LP When the UCI upper limit ratio is used to calculate the actual number of resource units in the first UCI, then α = α HP The proportion of the upper limit of UCI in the actual number of resource units of the second UCI is α = α LP .

[0234] When the PUSCH transmits both UCI information and uplink data information, the actual number of resource units in the first UCI satisfies:

[0235]

[0236] Q' HP-UCI The number of actual resource units in the first UCI, O HP-UCI L is the number of bits in the first UCI before encoding. HP-UCI The number of CRC bits for the first UCI. The rate offset factor for the first UCI. The bit rate of the uplink data. =The total number of resource units available on PUSCH for transmitting UCI, where l0 is 0 or is the symbol index of the first symbol that does not carry the first demodulation reference signal DMRS after the first demodulation reference signal DMRS.

[0237] It should be understood that when the first UCI is a high-priority CSI message, l0 is 0; when the first UCI is a high-priority HARQ feedback message, l0 is the symbol index of the first symbol that does not carry the first DMRS after the first demodulated reference signal DMRS.

[0238] The second UCI actual resource unit number satisfies:

[0239]

[0240] Q' LP-UCI For the second UCI actual resource unit number, O LP-UCI L is the number of bits in the second UCI before encoding. LP-UCI The number of CRC bits for the second UCI. This is the rate offset factor for the second UCI. The bit rate of the uplink data. =The total number of resource units available on PUSCH for transmitting UCI, where l0 is 0 or is the symbol index of the first symbol that does not carry the first demodulation reference signal DMRS after the first demodulation reference signal DMRS.

[0241] When the PUSCH transmits UCI information but not uplink data information, the actual number of the first UCI resource units satisfies:

[0242]

[0243] Among them, Q' HP-UCI The number of actual resource units in the first UCI, O HP-UCI L is the number of bits in the first UCI before encoding. HP-UCI The number of CRC bits for the first UCI. R is the rate offset factor for the first UCI, R is the PUSCH rate, and Q is the bitrate offset factor. m The modulation order of PUSCH. =The total number of resource units available on PUSCH for transmitting UCI, where l0 is 0 or is the symbol index of the first symbol that does not carry the first demodulation reference signal DMRS after the first demodulation reference signal DMRS.

[0244] The second UCI actual resource unit number satisfies:

[0245]

[0246] Among them, Q' LP-UCI For the second UCI actual resource unit number, O LP-UCI L is the number of bits in the second UCI before encoding. LP-UCI The number of CRC bits for the second UCI. R is the rate offset factor for the second UCI, R is the PUSCH rate, and Q is the rate offset factor for the second UCI. m The modulation order of PUSCH. =The total number of resource units available on PUSCH for transmitting UCI, where l0 is 0 or is the symbol index of the first symbol that does not carry the first demodulation reference signal DMRS after the first demodulation reference signal DMRS.

[0247] For example, when configuration information is used to indicate the upper limit ratio α of the number of resource units in the second UCI. LP The ratio α of the sum of the upper limits of the number of resource units in the first UCI and the second UCI HP+LP When the UCI upper limit ratio is used to calculate the actual number of resource units in the first UCI, then α = αHP+LP -α LP The proportion of the upper limit of UCI in the actual number of resource units of the second UCI is α = α LP .

[0248] When the PUSCH transmits both UCI information and uplink data information, the actual number of resource units in the first UCI satisfies:

[0249]

[0250] The meanings of the parameters in formula (12) are the same as those in formula (8), and will not be repeated here.

[0251] The actual number of resource units in the second UCI satisfies formula (9), which will not be elaborated here.

[0252] When the PUSCH transmits UCI information but not uplink data information, the actual number of the first UCI resource units satisfies:

[0253]

[0254] The meanings of the parameters in formula (13) are the same as those in formula (10), and will not be repeated here.

[0255] The actual number of resource units in the second UCI satisfies formula (11), which will not be elaborated here.

[0256] For example, when the configuration information is used to indicate the ratio α of the sum of the upper limits of the number of resource units in the first UCI and the second UCI. HP+LP And the ratio p of the upper limit of the number of first UCI resource units to the sum of the upper limits of the number of first UCI and second UCI resource units. HP When the UCI upper limit ratio is used to calculate the actual number of resource units in the first UCI, then α = p HP ·α HP+LP The upper limit ratio of UCI in the actual number of resource units of the second UCI is α = (1-p HP )·α HP+LP .

[0257] When the PUSCH transmits both UCI information and uplink data information, the actual number of resource units in the first UCI satisfies:

[0258]

[0259] The meanings of the parameters in formula (14) are the same as those in formula (8), and will not be repeated here.

[0260] The second UCI actual resource unit number satisfies:

[0261]

[0262] The meanings of the parameters in formula (15) are the same as those in formula (9), and will not be repeated here.

[0264]

[0265] The meanings of the parameters in formula (16) are the same as those in formula (10), and will not be repeated here.

[0266] The second UCI actual resource unit number satisfies:

[0267]

[0268] The meanings of the parameters in formula (17) are the same as those in formula (11), and will not be repeated here.

[0269] The calculation of the actual number of resource units corresponding to different configuration information is similar and will not be elaborated here. This application embodiment does not limit this.

[0270] In the prior art, the upper limit ratio of different priorities is only used to control the actual number of resource units mapped by UCI on PUSCH to not exceed the upper limit of the number of resource units of UCI on PUSCH. In the embodiments of this application, the upper limit ratio not only has this function, but is also used to help determine the upper limit of the number of resource units mapped by the first UCI on PUSCH to determine the position where the second UCI starts to be mapped on PUSCH, so as to ensure that when the first UCI has a mapping error during the encoding process, it will not affect the network device's decoding of the second UCI.

[0271] S505, perform resource mapping on PUSCH according to the starting position of the first UCI and the second UCI mapping on PUSCH and the actual number of resource units.

[0272] Corresponding to Figure 4 In step S403, the first UCI is mapped on the PUSCH according to the starting position of the first UCI mapping on the PUSCH and the actual number of resource units of the first UCI, and the second UCI is mapped on the PUSCH according to the starting position of the second UCI mapping on the PUSCH and the actual number of resource units of the second UCI.

[0273] In this embodiment, the mapping order of UCI information and uplink data information on the PUSCH is first UCI, second UCI and uplink data information. Uplink data only appears when UCI information and data information need to be multiplexed on the same uplink channel total time-frequency resource. If the uplink channel does not need to transmit uplink data information, then there is no need to map data information on the PUSCH.
