[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on August 10, 2023, with application number 202311013865.7, and priority to the Chinese patent application entitled “Communication Methods, Devices and Systems”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and more specifically, to a communication method and apparatus. Background Art

[0003] Currently, green energy conservation is crucial for the continued evolution of communications technology. Researchers have proposed cell discontinuous reception (DRX) technology. When the base station load is low, the base station can configure active and inactive periods for each cell. During each cell's inactive period, terminals do not send certain types of uplink information, and the base station does not receive certain types of uplink information, allowing it to sleep. This reduces power consumption for both terminals and the base station.

[0004] For uplink transmission, to save uplink information resource overhead, different types of uplink information can be sent on the same time-frequency resources. This approach is referred to as uplink information multiplexing. Current research on Cell DRX does not consider uplink information multiplexing. Specifically, during periods of inactivity in a cell, some types of uplink information do not need to be transmitted. If this unnecessary uplink information needs to be multiplexed with other uplink information, how should the terminal handle this? This is a pressing issue.

[0005] Summary of the Invention

[0006] The present application provides a communication method, device and system, which can improve communication reliability.

[0007] In a first aspect, a communication method is provided, which can be executed by a terminal, or by a chip or circuit used in the terminal. For ease of description, the following description is made using the terminal as an example.

[0008] The method includes: the terminal receives first indication information, the first indication information indicates that the cell discontinuous reception Cell DRX configuration is effective, the Cell DRX configuration indicates that the first uplink information is not transmitted in the first time period of the first cycle, and the first cycle is the cycle of Cell DRX; when the first uplink information and the second uplink information meet the multiplexing conditions, and the transmission resources of the first uplink information overlap with the first time period, the terminal determines the first uplink information; the terminal sends the third uplink information after the first uplink information and the second uplink information are multiplexed.

[0009] In this method, when the base station configures, via cell DRX, not to transmit the first uplink information during the first time period of the first cycle, but the first uplink information and the second uplink information need to be multiplexed, the uplink information actually sent by the terminal is the multiplexed first uplink information and the second uplink information. This method ensures that the Cell DRX configuration does not affect the UCI multiplexing process. For example, the Cell DRX configuration does not affect the number of bits and transmission resources of the uplink information in the UCI multiplexing scenario, thereby improving the stability and reliability of UCI multiplexing transmission.

[0010] For example, even if the terminal misses the DCI for activating / deactivating Cell DRX, it can still correctly receive the UCI information, thus avoiding the problem that the network equipment cannot correctly receive uplink information, avoiding affecting communication, and improving communication reliability.

[0011] In some implementations, the first uplink information includes at least one of the following: configuration authorization physical uplink shared channel CG PUSCH, periodic channel state information P-CSI, semi-static channel state information SP-CSI, scheduling request SR, and hybrid automatic repeat request confirmation HARQ-ACK corresponding to the semi-statically scheduled physical downlink shared channel SPS PDSCH.

[0012] In some implementations, the second uplink information includes at least one of the following: a dynamically granted physical uplink shared channel DG PUSCH, aperiodic channel state information A-CSI, and a HARQ-ACK corresponding to a dynamically granted physical downlink shared channel DG PDSCH.

[0013] In certain implementations, when the first uplink information includes P / SP-CSI, determining the first uplink information includes: determining that the P / SP-CSI included in the first uplink information is the channel state information CSI obtained by the most recent measurement, or setting all bits of the P / SP-CSI to 0 or all to 1.

[0014] In some implementations, when the first uplink information includes an SR, determining the first uplink information includes: determining that the SR included in the first uplink information is a negative SR.

[0015] In some implementations, the SR is an SR with a physical layer priority configured as 0, and / or the SR is an SR associated with a low-priority logical channel LCH of a media access control MAC layer.

[0016] In certain implementations, when the first uplink information includes HARQ-ACK information corresponding to the SPS PDSCH, determining the first uplink information includes: determining that the HARQ-ACK information included in the first uplink information is a negative acknowledgment (NACK).

[0017] In certain implementations, the method further includes: when the first uplink information is not multiplexed with the second uplink information and a transmission resource of the first uplink information overlaps with the first time period, the terminal does not transmit the first uplink information.

[0018] That is, when the first uplink information is transmitted independently, or in other words, the first uplink information does not need to be multiplexed with other information, the terminal does not send the first uplink information in the first time period of the first cycle according to the cell DRX configuration.

[0019] In this manner, when there is only the first uplink information in the first time period, the first uplink information is not transmitted, thereby further reducing the power consumption of the terminal and the network device.

[0022] In some implementations, the first uplink information includes at least one of the following: CG PUSCH, P-CSI, semi-static channel state information SP-CSI, SR, and HARQ-ACK corresponding to SPS PDSCH.

[0023] In certain implementations, the second uplink information includes at least one of the following: DG PUSCH, A-CSI, and HARQ-ACK corresponding to DG PDSCH.

[0024] In some implementations, when the first uplink information includes P / SP-CSI, the P / SP-CSI included in the first uplink information is the CSI obtained by the most recent measurement, or all bits of the P / SP-CSI are set to 0 or all are set to 1.

[0025] In some implementations, when the first uplink information includes an SR, the SR is a negative SR.

[0026] In some implementations, the SR is an SR with a physical layer priority configured as 0, and / or the SR is an SR associated with a MAC layer low priority LCH.

[0027] In certain implementations, when the first uplink information includes HARQ-ACK information corresponding to the SPS PDSCH, the HARQ-ACK information corresponding to the SPS PDSCH is NACK.

[0061] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0062] Figure 1 is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in Figure 1 , the communication system includes a radio access network 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet 300. The radio access network 100 may include at least one radio access network device (such as 110a and 110b in Figure 1 ) and at least one terminal (such as 120a-120j in Figure 1 ). The terminal is wirelessly connected to the radio access network device, and the radio access network device is wirelessly or wiredly connected to the core network. The core network device and the radio access network device may be independent, distinct physical devices, or the core network device's functions and the radio access network device's logical functions may be integrated into the same physical device, or a single physical device may integrate some of the core network device's functions and some of the radio access network device's functions. Terminals and radio access network devices may be interconnected via wired or wireless connections. Figure 1 is merely a schematic diagram. The communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices, which are not shown in Figure 1 .

[0063] A radio access network device can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a Wi-Fi system. It can also be a module or unit that performs some of the functions of a base station, such as a centralized unit (CU) or a distributed unit (DU). The CU performs the functions of the base station's radio resource control protocol and packet data convergence protocol (PDCP), as well as the service data adaptation protocol (SDAP). The DU performs the functions of the base station's radio link control layer and medium access control (MAC) layer, as well as some or all of the physical layer. For detailed descriptions of each of these protocol layers, please refer to the relevant technical specifications of the Third Generation Partnership Project (3GPP). The wireless access network device can be a macro base station (such as 110a in Figure 1), a micro base station or an indoor station (such as 110b in Figure 1), a relay node, a donor node, etc. The embodiments of this application do not limit the specific technology and device form used by the wireless access network device. For ease of description, the following description uses a base station as an example of a wireless access network device.

[0064] A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. The terminal can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. The terminal can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, drone, helicopter, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.

[0065] Base stations and terminals can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0066] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1 can be configured as a mobile base station. To terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station. However, to base station 110a, 120i is a terminal, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1 can be referred to as communication devices with base station functionality, while 120a-120j in Figure 1 can be referred to as communication devices with terminal functionality.

[0067] Communication between base stations and terminals, between base stations, and between terminals can be carried out through authorized spectrum, unauthorized spectrum, or both; communication can be carried out through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0068] In the embodiments of the present application, the functions of the base station may also be performed by a module (such as a chip) in the base station, or by a control subsystem that includes the base station functions. The control subsystem that includes the base station functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal may also be performed by a module (such as a chip or modem) in the terminal, or by a device that includes the terminal functions.

[0069] The technical solutions provided in the embodiments of this application can be applied to wireless communications between communication devices. Wireless communications between communication devices may include: wireless communications between network devices and terminals, wireless communications between network devices, and wireless communications between terminals. In the embodiments of this application, the term "wireless communications" may also be referred to as "communication," which may also be described as "data transmission," "information transmission," or "transmission."

[0070] It can be understood that in the embodiments of the present application, the physical downlink share channel (PDSCH), the physical downlink control channel (PDCCH) and the physical uplink share channel (PUSCH) are merely examples of downlink data channels, downlink control channels and uplink data channels, respectively. In different systems and different scenarios, data channels and control channels may have different names, and the embodiments of the present application do not limit this.

[0071] In order to facilitate understanding of the solutions of the embodiments of the present application, the relevant concepts are explained.

[0072] The current NR protocol defines a variety of uplink control information (UCI): such as Hybrid Automatic Repeat Request-acknowledgment (HARQ-ACK), Scheduling Request (SR) and Channel State Information (CSI). Different UCIs perform different functions, specifically:

[0073] HARQ-ACK: Its primary function is to report the transmission status of the corresponding downlink transmission (or downlink PDSCH) to the base station. For each transmission unit (which may be a transport block (TB) or code block group (CBG), determined and pre-configured by the base station), it reports an ACK (indicating successful reception) or a NACK (indicating unsuccessful reception). For example, the ACK / NACK for each transmission unit occupies 1 bit.

[0074] At the same time, HARQ-ACK can also be divided into HARQ-ACK corresponding to the dynamically scheduled PDSCH (Dyanmic Grant PDSCH, DG PDSCH) and HARQ-ACK corresponding to the semi-persistently scheduled PDSCH (Semi-persistent Scheduling PDSCH, SPS PDSCH) according to the corresponding data transmission channel type.

[0075] As shown in (a) of Figure 2, for the HARQ-ACK corresponding to the DG PDSCH, its reporting timing is indicated by the PDSCH-to-HARQ_feedback timing indicator field in the downlink control information (DCI) that schedules the PDSCH. That is, the terminal only needs to send HARQ-ACK every time the base station sends the DCI that schedules the DG PDSCH.

[0076] As shown in (b) of Figure 2, for SPS PDSCH, once the UE receives an activated DCI (the DCI includes the PDSCH-to-HARQ_feedback timing indicator), the terminal will send HARQ-ACK in the Xth time slot after each SPS PDSCH transmission opportunity according to the time slot offset X indicated in the DCI. That is, once the SPS PDSCH configuration is activated, its corresponding HARQ-ACK is sent periodically.

[0077] At the same time, as shown in Figure 3, for data transmissions in different time slots, the corresponding HARQ-ACK information may be fed back in the same time slot. In this case, the terminal needs to combine the HARQ-ACK information corresponding to multiple data transmissions to generate a HARQ-ACK codebook, which includes multiple HARQ-ACK bit information to be transmitted in the current time slot.

[0078] CSI: Its main function is to report channel state information to the base station. Specifically, it can be divided into periodic CSI (P-CSI), semi-persistent CSI (SP-CSI), and aperiodic CSI (A-CSI) according to the configuration type.

[0079] Different types of CSI are configured differently. For P / SP-CSI, as shown in Figure 4(a), once the configuration (configuration information, including P / SP CSI activation information) is activated, the CSI needs to be transmitted periodically. For A-CSI, as shown in Figure 4(b), it is activated once by DCI and is transmitted only once according to the corresponding DCI schedule.

[0080] SR: Its main function is to apply for uplink transmission resources from the base station.

[0081] Specifically, as shown in FIG5 , the transmission resources of the SR are periodically configured. At each transmission opportunity, when an uplink resource needs to be applied for, the terminal sends a positive SR; otherwise, the terminal sends a negative SR.

[0082] At the same time, SR can be divided into types according to different functions, such as SR associated with logical channels (different physical layer / MAC layer priorities), SR associated with secondary cell (SCell) beam failure recovery (BFR), etc.

[0083] Generally speaking, a terminal will only transmit one uplink channel in a time slot. However, when the following situations occur, the terminal needs to multiplex multiple uplink transmission information and integrate them into one uplink channel for transmission. For example:

[0084] Multiple UCIs overlap in the time domain: At this time, the terminal will determine a PUCCH resource based on the transmission type, priority, and corresponding PUCCH resource of each UCI. The PUCCH resource can be the PUCCH resource corresponding to the current UCI or a new PUCCH resource determined based on the overall overhead of multiple UCIs. Multiplexed uplink information is generated based on the one or more UCIs, and the multiplexed uplink information is transmitted based on the determined PUCCH resource. As shown in (a) of Figure 6, the figure generates multiplexed uplink information based on the HARQ-ACK of the SR and SPS PDSCH.

[0085] As shown in (b) of Figure 6 , the transmission resources of one or more UCIs overlap with uplink data transmission (PUSCH) in the time domain. In this case, the terminal generates multiplexed uplink information based on the one or more UCIs and transmits the uplink information on the PUSCH, which is also called on-link reporting.

[0086] Compared to the downlink SPS PDSCH, uplink data transmission also has a periodic transmission mode called Configured Grant (CG) PUSCH. Once the CG PUSCH configuration is activated, the terminal can transmit the required uplink data on the corresponding periodic transmission resources, as shown in Figure 7.

[0087] To reduce base station power consumption in low- to medium-load scenarios, researchers have proposed cell discontinuous transmission (DTX) / cell discontinuous reception (DRX) energy-saving technology. DTX / DRX is a power-saving technology for the RRC connected (RRC_CONNECTED) state.

[0088] As shown in Figure 8, the Cell DTX / DRX configuration cycle includes active and inactive periods. During the inactive periods, the base station and terminal simultaneously do not transmit certain signals / channels. The following describes the signals or channels that are not transmitted during the inactive periods of Cell DTX and Cell DRX, respectively.

[0089] For Cell DTX, the channels / signals not transmitted during the inactive period are one or more of the following:

[0090] SPS PDSCH, periodic CSI-RS (PCSI-RS) for CSI reporting, semi-static CSI-RS (SP CSI-RS) for CSI reporting.

[0091] For Cell DRX, channels / signals not transmitted during inactive periods include one or more of the following:

[0092] HARQ-ACK corresponding to CG PUSCH, SR, P / SP-CSI, and SPS PDSCH.

[0093] The SR may be a low MAC layer priority logical channel association / low physical layer priority SR.

[0094] By not transmitting these signals / channels during inactive periods, both the base station and the terminal can further save power consumption.

[0095] At the same time, Cell DTX / DRX also supports activation / deactivation through multicast downlink control signaling (Group-common DCI), that is, dynamically indicating whether the Cell DTX / DRX cycle configuration is effective.

[0096] During the inactive period of Cell DRX, some UCI and CG PUSCH are not transmitted. At the same time, during the inactive period of Cell DTX, SPS PDSCH will not be transmitted. For this part of UCI, please refer to the description of UCI not transmitted during the inactive period of Cell DRX.

[0097] At the same time, DCI-based activation / deactivation is introduced in Cell DTX / DRX. That is, Cell DTX / DRX can be activated or deactivated by DCI. When the terminal does not detect the DCI sent by the base station side, the terminal and the base station cannot align to activate or deactivate Cell DTX / DRX. Since the terminal does not know the specific instructions of the base station at this time, it is impossible to determine whether the UCI and CG PUSCH that cannot be transmitted during the inactive period and the SPS PDSCH that is not transmitted during the inactive period should be transmitted during the corresponding inactive period. Furthermore, during the Cell DRX inactive period, when the transmission resources of multiple UCIs and / or PUSCHs overlap in the time domain, the base station cannot determine the specific number of UCI bits transmitted by the terminal (or the UCI payload) and the transmission resources used, and therefore cannot correctly receive the multiplexed UCI. This will have a great impact on the transmission performance.

[0098] In view of this, the present application proposes a communication method, which can be applied between a base station and a terminal, and can enable the terminal to send uplink information in a timely manner to avoid affecting communication.

[0099] As shown in FIG9 , the method includes the following steps:

[0100] 910. The base station sends first indication information to the terminal. Correspondingly, the terminal receives the first indication information.

[0101] The first indication information indicates that the discontinuous reception (DRX) configuration is effective. The DRX configuration indicates that the first uplink information is not transmitted in the first time period of the first cycle.

[0102] The first cycle is a DRX cycle. The first time period is an inactive period within the first cycle.

[0103] For example, as shown in Figure 8, the first cycle may be a cycle configured by DRX. The first time period may be an inactive period within the cycle configured by DRX.

[0104] It should be understood that the duration of the first cycle and the duration of the first time period may be DRX configured.

[0105] Optionally, the first period may also be one or more periods in at least one period, where the at least one period is a period configured for DTX.

[0106] It should also be understood that the DRX configuration is at the cell level. That is, the DRX configuration is Cell DRX. In other words, an alternative name for DRX is Cell DRX.

[0107] The first uplink information is information that is not allowed to be transmitted in the first time period according to the DRX configuration, or in other words, the first uplink information is information affected by the DRX configuration in the first time period.

[0108] The first uplink information may be at least one of the following:

[0109] HARQ-ACK corresponding to CG PUSCH, P-CSI, SP-CSI, SR, and SPS PDSCH.

[0110] The HARQ-ACK corresponding to the SPS PDSCH may be understood as a HARQ-ACK that feeds back the reception status of the SPS PDSCH.

[0111] The SR is an SR with a physical layer priority configured as 0, for example, an SR with the phy-PriorityIndex-r16 field configured as p0.

[0112] Alternatively, the SR is an SR associated with a logical channel (Logical Channel, LCH) with a low priority at the MAC layer. For example, the SR is associated with a logical channel with a MAC priority greater than or equal to X, or the SR is associated with a logical channel with a priority configuration (LogicalChannelConfig) less than and / or equal to X, where X is an integer less than or equal to 16.

[0113] In other words, the SR associated with the low-priority logical channel LCH of the MAC layer can be understood as: an SR greater than or equal to a preset threshold, and the preset threshold can be preconfigured or configured.

[0114] For example, the preset threshold is a threshold of a priority configuration value. For example, if the preset threshold of the priority configuration value is 6, then an SR with a priority configuration value greater than or equal to 6 is an SR associated with a low-priority logical channel LCH of the MAC layer.

[0115] Alternatively, multiple LCH-associated SRs are configured at the same time, among which some LCH-associated SRs with higher priority configuration values ​​are configured.

[0116] For example, the priority configuration value of LCH#A is 1, the priority configuration value of LCH#B is 5, and the priority configuration value of LCH#C is 10. In one possible implementation, the SR associated with the low-priority logical channel LCH at the MAC layer is LCH#C. In another possible implementation, the SRs associated with the low-priority logical channel LCH at the MAC layer are LCH#C and LCH#B.

[0117] 920. When the first uplink information and the second uplink information meet a multiplexing condition and the transmission resource of the first uplink information overlaps with the first time period, the terminal determines the first uplink information.

[0118] The second uplink information is different from the first uplink information. In other words, the second uplink information does not belong to the first uplink information. In other words, the first uplink information and the second uplink information are different types of information. In other words, the first uplink information cannot be transmitted in the first time period of the first cell DRX cycle, while the second uplink information can be transmitted in the first time period of the first cell DRX cycle. In other words, the transmission of the first uplink information is affected by the cell DRX configuration, while the transmission of the second uplink information is not affected by the cell DRX configuration.

[0119] The first uplink information and the second uplink information satisfying the multiplexing condition can be understood as the transmission resources corresponding to the first uplink information and the second uplink information overlapping in the time domain, or the first uplink information and the second uplink information need to be transmitted in one time slot, and it can be considered that the first uplink information and the second uplink information meet the conditions for multiplexing.

[0120] The transmission resources for the first uplink information or the second uplink information can be understood as resources configured for the first uplink information or the second uplink information. Alternatively, they can be resources that can be used to transmit the first uplink information or resources that can be used to transmit the second uplink information. In other words, the first uplink information or the second uplink information has not yet been sent on the configured resources.

[0121] The transmission resources include time domain resources and frequency domain resources.

[0122] In one possible manner, the time domain resource of the first uplink information is within the first time period. As shown in FIG10(a), the starting position and the ending position of the time domain resource of the first uplink information are both within the first time period.

[0123] In another possible embodiment, a portion of the time domain resources of the first uplink information is within the first time period. As shown in FIG10(b), the starting position of the time domain resources of the first uplink information is within the first time period, but the ending position of the time domain resources of the first uplink information is not within the first time period. Alternatively, as shown in FIG10(c), the ending position of the time domain resources of the first uplink information is within the first time period, but the starting position of the time domain resources of the first uplink information is not within the first time period.

[0124] If the starting position or ending position of the time domain resource overlaps with the first time period, the starting position or ending position of the time domain resource is considered to be within the first time period. As shown in (d) of Figure 10, the ending position of the time domain resource of the first uplink information is the same as the starting position of the first time period; or, as shown in (e) of Figure 10, the starting position of the time domain resource of the first uplink information is the same as the ending position of the first time period, the time domain resource of the first uplink information is considered to be within the first time period.

[0125] It should be understood that the first uplink information may correspond to one or more UCIs or PUSCHs. As long as the transmission resources of one or more UCIs or PUSCHs overlap with the first time period, it is deemed that the transmission resources of the first uplink information overlap with the first time period.

[0126] That is to say, the first uplink information and / or the second uplink information in the present application may include one or more uplink information.

[0127] Determining the first uplink information may be determining the content of the first uplink information. That is, when the first uplink information includes a certain type of UCI and the UCI is not originally transmitted in the first time period of the first DRX cycle, the terminal needs to determine the specific content of the UCI when transmitting.

[0128] In the above situation, the following possibilities may be used to determine the first uplink information:

[0129] Possibility 1: When the first uplink information includes P / SP-CSI, the terminal determines that the P / SP-CSI included in the first uplink information is the channel state information CSI obtained by the latest measurement.

[0130] In other words, when the first uplink information includes P / SP-CSI and the third uplink information includes the first uplink information, the terminal determines that the P / SP-CSI included in the first uplink information is the channel state information CSI obtained by the latest measurement.

[0131] The third uplink information is information multiplexed from the first uplink information and the second uplink information.

[0132] The replacement statement here also applies to the following possibilities, so I will not elaborate on it.

[0133] Optionally, the channel state information (CSI) obtained in the most recent measurement may be of two types:

[0134] Case ①: The last CSI report corresponding to this CSI configuration.

[0135] Case ②: The latest measurement result of the CSI-RS corresponding to the CSI configuration, or in other words, the real-time measurement result of the CSI-RS corresponding to the CSI configuration.

[0136] For example, when cell DTX is in effect and the CSI-RS corresponding to the P / SP-CSI is in the inactive period of cell DTX, the CSI-RS measurement result is the last measurement result before the end of the cell DTX active period; when cell DTX is not in effect, or the corresponding CSI-RS is in the active period of cell DTX, the measurement result is the latest measurement result.

[0137] Alternatively, the terminal sets all bits of the P / SP-CSI to 0 or all bits to 1. That is, the terminal fills the bits of the P / SP-CSI with content that does not contain specific meaning.

[0138] Optionally, the terminal may also fill the bits of the P / SP-CSI with other invalid values, not limited to 0 or 1.

[0139] Possibility 2: When the first uplink information includes an SR, the SR included in the first uplink information is determined to be a negative SR. That is, regardless of whether there is an uplink transmission requirement (such as data transmission, sending a BFR MAC CE, etc.), the terminal sends a negative SR. In other words, even if there is an uplink transmission requirement (such as the terminal has uplink data to transmit, or reports a BFR MAC CE, etc.), the terminal also sends a negative SR.

[0140] In this mode, when Cell DRX is configured not to transmit SR during an inactive period, the SR may be a low-priority SR at the physical layer or an SR associated with a low-priority logical channel at the MAC layer, but the SR needs to be multiplexed with the second uplink information so that Cell DRX does not affect the number of uplink information bits and transmission resources multiplexed by UCI. At the same time, considering that the SR is associated with subsequent transmissions (for example, scheduling of uplink information), in order not to affect the configuration of Cell DRX (that is, not transmitting SR during an inactive period, that is, not wanting uplink scheduling), regardless of whether the terminal has an uplink transmission requirement at this time (or even if the terminal device has an uplink transmission requirement), the SR is processed as a negative SR and multiplexed with the second uplink information. This mode can ensure the stability of UCI multiplexing.

[0141] In possibility 2, another possible manner is that the terminal determines whether the SR is a positive SR or a negative SR according to actual needs.

[0142] For example, for an LCH-associated SR, if there is an uplink transmission requirement, a positive SR is sent; otherwise, a negative SR is sent.

[0143] Possibility 3: When the first uplink information includes HARQ-ACK information corresponding to the SPS PDSCH, the HARQ-ACK information included in the first uplink information is determined to be a NACK. In other words, a NACK is generated for the HARQ-ACK information corresponding to the SPS PDSCH. In other words, regardless of the reception status of the SPS PDSCH, the terminal reports a NACK.

[0144] Alternatively, the content of the HARQ-ACK information corresponding to the SPS PDSCH is determined according to the actual SPS transmission situation, for example:

[0145] When the terminal correctly decodes the SPS PDSCH, it generates an ACK;

[0146] When the terminal fails to correctly decode the SPS PDSCH, a NACK is generated.

[0147] Alternatively, the terminal determines the HARQ-ACK information corresponding to the SPS PDSCH according to the DTX configuration. For example:

[0148] Before the transmission resource of the first uplink information overlaps with the first time period in the time domain, the terminal further receives second indication information, which instructs the terminal not to transmit the SPS PDSCH in the second time period of the second cycle.

[0149] If the overlapping time is within the second time period, the terminal generates a NACK for the HARQ-ACK information corresponding to the SPS PDSCH;

[0150] If the overlapping moment is not within the second time period, that is, the SPS PDSCH can be transmitted normally, the terminal reports ACK or NACK according to the actual reception status of the SPS PDSCH. For example, when the terminal correctly decodes the SPS PDSCH, an ACK is generated; when the terminal does not correctly decode the SPS PDSCH, a NACK is generated.

[0151] The second period and second time period are part of the DTX configuration. In other words, the period and inactive period are part of the DTX configuration information. The DTX is at the cell level. That is, the DTX is called cell DTX. Alternatively, an alternative name for DTX is cell DTX.

[0152] When the first uplink information and the second uplink information are multiplexed in the inactive period of Cell DRX, transmitting or not transmitting the first uplink information will affect the number of bits of the uplink information finally transmitted (or load, or effective load), as well as the resources used for uplink information transmission. If the terminal misses the DCI that activates or deactivates Cell DRX, the terminal cannot determine whether Cell DRX is activated or deactivated, and cannot determine whether the first uplink information can be transmitted in the inactive time period of Cell DRX (the first time period of the first cycle). Furthermore, the network device cannot correctly receive the uplink information sent by the terminal. In this way, the terminal determines the HARQ-ACK information corresponding to the SPS PDSCH as NACK, and multiplexes it with the second uplink information, so that the Cell DRX configuration does not affect the number of bits and transmission resources of the uplink information in the UCI multiplexing scenario. Furthermore, the network device can correctly receive the multiplexed uplink information, thereby improving communication reliability.

[0153] 930. The terminal sends third uplink information multiplexed from the first uplink information and the second uplink information to the base station. Correspondingly, the base station receives the third uplink information.

[0154] Before the terminal sends the third uplink information, the terminal may determine the third uplink information based on the first uplink information and the second uplink information.

[0155] The third uplink information may include the content of the first uplink information and the content of the second uplink information.

[0156] It should be understood that the content of the first uplink information determined in 920 may or may not be included in the third uplink information. That is, the third uplink information is the information multiplexed from the first uplink information and the second uplink information, and does not necessarily include all or part of the content of the first uplink information. For the specific multiplexing method, please refer to the multiplexing method in the protocol and will not be described in detail.

[0157] For example, if the first uplink information is SR, the second uplink information is DG HARQ-ACK, the transmission resource associated with SR is PUCCH format 0, and the transmission resource associated with HARQ-ACK is PUCCH Format 1, then SR is not transmitted and only ACK information is sent.

[0158] In addition, when the first uplink information is not multiplexed with the second uplink information and the first uplink information overlaps with the first time period, the first uplink information is not transmitted. That is, if the first uplink information is transmitted alone and the transmission resources of the first uplink information overlap with the first time period, the terminal does not send the first uplink information.

[0159] When the first uplink information and the second uplink information are multiplexed in the inactive period of Cell DRX, transmitting or not transmitting the first uplink information will affect the number of bits of the uplink information finally transmitted (or load, or effective load), as well as the resources used for uplink information transmission. If the terminal misses the DCI that activates or deactivates Cell DRX, the terminal cannot determine whether Cell DRX is activated or deactivated, and cannot determine whether the first uplink information can be transmitted in the inactive time period of Cell DRX (the first time period of the first cycle). Furthermore, the network device cannot correctly receive the uplink information sent by the terminal. In this method, regardless of whether the first uplink information is in the active state or the inactive state of DRX, the terminal can determine that when the first uplink information and the second uplink information are multiplexed, it is always necessary to generate multiplexed information based on the first uplink information and the second uplink information, that is, the third uplink information. This ensures that the Cell DRX configuration does not affect the number of bits and transmission resources of the uplink information in the UCI multiplexing scenario, so that the base station can correctly receive the multiplexed uplink information. The terminal can clearly understand the specific content of the first uplink signal when sending it, and the terminal and the base station have a consistent understanding of the UCI multiplexing rules. This avoids the problem of the base station being unable to correctly receive the UCI and PUSCH sent by the terminal when the terminal and the base station are not aligned (for example, the terminal does not receive the activation / deactivation DCI sent by the base station), avoiding communication impact and improving communication reliability.
