Description

Technical Field

[0001] The present application relates to the field of communications, and in particular to a communication method, device and system. Background Art

[0002] At present, green energy saving is particularly important for the continuous evolution of communication technology. On the one hand, researchers have proposed the cell discontinuous reception (cell DRX) technology. When the base station side load is not large, the base station can configure active / inactive periods for each cell. During the inactive period of each cell, the terminal does not send some types of uplink information, and the base station does not receive some types of uplink information during the inactive period of each cell. It can sleep, so as to save power consumption of the terminal and the base station.

[0003] For uplink transmission, in order to save the resource overhead of uplink information, different uplink information can be sent on the same time-frequency resources. This method is referred to as uplink information multiplexing. The current research on Cell DRX does not take into account the multiplexing of uplink information. That is, during the inactive period of the cell, some types of uplink information do not need to be sent. If these uplink information that does not need to be sent need to be multiplexed with other uplink information, how the terminal handles it is a problem that needs to be solved urgently. Summary of the invention

[0004] The present application provides a communication method, device and system, wherein the communication method can improve communication reliability.

[0005] In a first aspect, a communication method is provided, which can be executed by a terminal, or can also be executed by a chip or circuit used in a terminal. For ease of description, the following description is made by taking the execution of the terminal as an example.

[0006] The method includes: a terminal receives first indication information, the first indication information indicates that a discontinuous reception Cell DRX configuration of the cell is effective, the Cell DRX configuration indicates that the first uplink information is not transmitted in a first time period of a first cycle, the first cycle being a Cell DRX cycle; when the first uplink information and the second uplink information meet a multiplexing condition, and a transmission resource of the first uplink information overlaps with the first time period, the terminal determines the first uplink information; the terminal sends the third uplink information multiplexed with the first uplink information and the second uplink information.

[0007] In this method, when the base station configures through cell DRX not to transmit the first uplink information in 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 information after the first uplink information and the second uplink information are multiplexed. This method ensures that the configuration of Cell DRX does not affect the multiplexing process of UCI, for example, the Cell DRX configuration does not affect the bit number and transmission resources of the uplink information in the UCI multiplexing scenario, which can improve the stability and reliability of UCI multiplexing transmission.

[0008] 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 device cannot correctly receive the uplink information, thus avoiding affecting the communication and improving the communication reliability.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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 logical channel LCH with a low priority of a media access control MAC layer.

[0014] 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 (Negative Acknowledgement, NACK).

[0015] 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.

[0016] That is, when the first uplink information is transmitted separately, 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 configuration of the cell DRX.

[0017] In this manner, when there is only 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.

[0020] 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.

[0021] In some implementations, the second uplink information includes at least one of the following: DG PUSCH, A-CSI, and HARQ-ACK corresponding to DGPDSCH.

[0022] 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 the bits of the P / SP-CSI are all set to 0 or all set to 1.

[0023] In some implementations, when the first uplink information includes an SR, the SR is a negative SR.

[0024] 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.

[0025] 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.

[0058] The technical solutions in the embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0059] Figure 1 FIG. 1 is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. Figure 1 As shown, the communication system includes a wireless access network 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet 300. The wireless access network 100 may include at least one wireless access network device (such as Figure 1 110a and 110b), and may further include at least one terminal (such as Figure 1 120a-120j in the figure). The terminal is connected to the wireless access network device by wireless means, and the wireless access network device is connected to the core network by wireless or wired means. The core network device and the wireless access network device can be independent and different physical devices, or the functions of the core network device and the logical functions of the wireless access network device can be integrated on the same physical device, or part of the functions of the core network device and part of the functions of the wireless access network device can be integrated on one physical device. Terminals and wireless access network devices can be connected to each other by wired or wireless means. Figure 1This is just a schematic diagram. The communication system may also include other network devices, such as wireless relay devices and wireless backhaul devices. Figure 1 Not drawn in.

[0060] The wireless access network equipment may be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in the fifth generation (5G) mobile communication system, a next generation base station in the sixth generation (6G) mobile communication system, a base station in a future mobile communication system, or an access node in a WiFi system, etc.; it may also be a module or unit that completes part of the functions of a base station, for example, it may be a central unit (CU) or a distributed unit (DU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and may also complete the functions of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and may also complete the functions of part or all of the physical layer. For the specific description of each of the above protocol layers, please refer to the relevant technical specifications of the 3rd generation partnership project (3GPP). The wireless access network device may be a macro base station (such as Figure 1 110a), or a micro base station or an indoor station (such as Figure 1 110b), may also be a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the wireless access network device. For ease of description, the following description takes a base station as an example of a wireless access network device.

[0061] The 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, for example, device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, automatic driving, telemedicine, smart grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal may be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, a drone, a helicopter, an airplane, a ship, a robot, a mechanical arm, a smart home device, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.

[0062] Base stations and terminals can be fixed or movable. Base stations and terminals can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on the water surface; they can also be deployed on airplanes, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0063] The roles of the base station and the terminal can be relative, for example, Figure 1 The helicopter or drone 120i in the figure can be configured as a mobile base station. For the terminal 120j that accesses the wireless access network 100 through 120i, the terminal 120i is a base station; but for the base station 110a, 120i is a terminal, that is, 110a and 120i communicate through the wireless air interface protocol. Of course, 110a and 120i can also communicate through the interface protocol between base stations. In this case, relative to 110a, 120i is also a base station. Therefore, base stations and terminals can be collectively referred to as communication devices. Figure 1 110a and 110b in the figure may be referred to as communication devices having base station functions. Figure 1 120a-120j in the figure can be called communication devices with terminal functions.

[0064] Base stations and terminals, base stations and base stations, and terminals and terminals can communicate through authorized spectrum, unauthorized spectrum, or both; they can communicate 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.

[0065] 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 including the base station function. The control subsystem including the base station function 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 a modem) in the terminal, or by a device including the terminal function.

[0066] The technical solution provided in the embodiment of the present application can be applied to wireless communication between communication devices. Wireless communication between communication devices may include: wireless communication between network devices and terminals, wireless communication between network devices and network devices, and wireless communication between terminals. In the embodiment of the present application, the term "wireless communication" may also be referred to as "communication", and the term "communication" may also be described as "data transmission", "information transmission" or "transmission".

[0067] 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.

[0068] In order to facilitate understanding of the solutions of the embodiments of the present application, the relevant concepts are explained.

[0069] 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:

[0070] HARQ-ACK: The main 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 a code block group (CBG), which is determined and configured in advance by the base station), ACK (representing successful reception) or NACK (representing unsuccessful reception) is reported. For example, the ACK / NACK of each transmission unit occupies 1 bit.

[0071] At the same time, HARQ-ACK can also be divided into HARQ-ACK corresponding to dynamically scheduled PDSCH (Dyanmic Grant PDSCH, DG PDSCH) and HARQ-ACK corresponding to semi-persistent scheduling PDSCH (Semi-persistent Scheduling PDSCH, SPS PDSCH) according to its corresponding data transmission channel type.

[0072] like Figure 2 As shown in (a), for the HARQ-ACK corresponding to the DG PDSCH, the reporting timing is indicated by the PDSCH-to-HARQ_feedbacktiming indicator field in the downlink control information (DCI) that schedules the PDSCH, that is, the terminal only needs to send HARQ-ACK each time the base station sends the DCI that schedules the DG PDSCH.

[0073] like Figure 2 As shown in (b), for SPS PDSCH, once the UE receives the 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.

[0074] At the same time, if Figure 3 As shown, for data transmission in different time slots, the corresponding HARQ-ACK information may be fed back in the same time slot. At this time, the terminal needs to generate a HARQ-ACK codebook for the HARQ-ACK information combination corresponding to multiple data transmissions, and the HARQ-ACK codebook includes multiple HARQ-ACK bit information that needs to be transmitted in the current time slot.

[0075] CSI: The main function is to report channel state information to the base station. Specifically, it may be divided into periodic CSI (P-CSI), semi-persistent CSI (SP-CSI), and aperiodic CSI (A-CSI) according to the configuration type.

[0076] Different types of CSI have different configuration methods, such as Figure 4 As shown in (a) of FIG. 1 , for P / SP-CSI, once the configuration (configuration information, including activation information of P / SP CSI) is activated, the CSI needs to be sent periodically. Figure 4 As shown in (b), for A-CSI, it is activated once by DCI, that is, it is only sent once according to the scheduling of the corresponding DCI.

[0077] SR: The main function is to apply for uplink transmission resources from the base station.

[0078] Specifically, Figure 5 As shown, the transmission resources of SR are periodically configured. At each transmission opportunity, when an uplink resource needs to be applied, the terminal sends a positive SR; otherwise, the terminal sends a negative SR.

[0079] At the same time, SR can be divided into types according to different functions, such as SR associated with (different physical layer / MAC layer priorities) logical channels, SR associated with secondary cell (SCell) beam failure recovery (Beam Failure Recovery, BFR), etc.

[0080] Generally speaking, a terminal will only transmit one uplink channel in one 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:

[0081] 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 it can be 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. Figure 6 As shown in (a), the figure generates multiplexed uplink information based on the HARQ-ACK of SR and SPSPDSCH.

[0082] like Figure 6As shown in (b), the transmission resources of one or more UCIs and the uplink data transmission (PUSCH) overlap in the time domain. At this time, 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-line reporting.

[0083] Compared with the downlink SPS PDSCH, there is also a periodic transmission mode in uplink data transmission, 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, such as Figure 7 shown.

[0084] On the other hand, in order to reduce the power consumption of the base station side in low and medium load scenarios, researchers proposed the cell discontinuous transmission (Cell DTX) / cell discontinuous reception (DRX) energy-saving technology. Cell DTX / DRX is an energy-saving technology for the RRC connected (RRC_CONNECTED) state.

[0085] like Figure 8 As shown, the cycle of the Cell DTX / DRX configuration includes an active period and an inactive period. During the inactive period, the base station and the terminal do not transmit some signals / channels at the same time. The following describes the signals or channels that are not transmitted during the inactive period of Cell DTX and Cell DRX respectively.

[0086] For Cell DTX, the channels / signals not transmitted during the inactive period are one or more of the following:

[0087] SPS PDSCH, periodic CSI-RS (P CSI-RS) for CSI reporting, semi-static CSI-RS (SP CSI-RS) for CSI reporting.

[0088] For Cell DRX, channels / signals not transmitted during the inactive period include one or more of the following:

[0089] HARQ-ACK corresponding to CG PUSCH, SR, P / SP-CSI, and SPS PDSCH.

[0090] The SR may be a low MAC layer priority logical channel association / low physical layer priority SR.

[0091] By not transmitting these signals / channels during inactive periods, both the base station and the terminal can further save power consumption.

[0092] 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 cycle configuration of Cell DTX / DRX is effective.

[0093] During the inactive period of Cell DRX, some UCI and CG PUSCH are not transmitted; meanwhile, 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.

[0094] 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 thus cannot correctly receive the multiplexed UCI. This will have a great impact on the transmission performance.

[0095] In view of this, the present application proposes a communication method, which can be applicable between a base station and a terminal, and can enable the terminal to send uplink information in a timely manner to avoid affecting communication.

[0096] like Fig. 9 As shown, the method comprises the following steps:

[0097] 910. The base station sends first indication information to the terminal, and correspondingly, the terminal receives the first indication information.

[0098] 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.

[0099] The first cycle is a DRX cycle. The first time period is an inactive period within the first cycle.

[0100] For example, you can refer to Figure 8 As shown, 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.

[0101] It should be understood that the duration of the first cycle and the duration of the first time period may be DRX configured.

[0102] Optionally, the first period may also be one or more periods in at least one period, and the at least one period is a period configured for DTX.

[0103] 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, the replacement name of DRX is Cell DRX.

[0104] 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.

[0105] The first uplink information may be at least one of the following:

[0106] HARQ-ACK corresponding to CG PUSCH, P-CSI, SP-CSI, SR, SPS PDSCH.

[0107] The HARQ-ACK corresponding to the SPS PDSCH may be understood as the HARQ-ACK that feeds back the reception status of the SPS PDSCH.

[0108] The SR is an SR whose physical layer priority is configured as 0, for example, an SR whose phy-PriorityIndex-r16 field is configured as p0.

[0109] Alternatively, the SR is an SR associated with a logical channel (Logical Channel, LCH) of low priority at the MAC layer. For example, an SR associated with a logical channel whose MAC priority is greater than or equal to X, or an SR associated with a logical channel whose priority configuration (priority) of the logical channel configuration (LogicalChannelConfig) is less than and / or equal to X, where X is an integer less than or equal to 16.

[0110] In other words, the SR associated with the low-priority logical channel LCH of the MAC layer may be understood as: an SR greater than or equal to a preset threshold, and the preset threshold may be preconfigured or configured.

[0111] For example, the preset threshold is a threshold of a priority configuration value. For example, if the threshold of the preset priority configuration value is 6, then the SR with a priority configuration value greater than or equal to 6 is the SR associated with the logical channel LCH of low priority at the MAC layer.

[0112] Alternatively, multiple LCH-associated SRs are configured at the same time, among which some LCH-associated SRs with higher priority configuration values ​​are configured.

[0113] 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 logical channel LCH of low priority at the MAC layer is LCH#C. In another possible implementation, the SR associated with the logical channel LCH of low priority at the MAC layer is LCH#C and LCH#B.

[0114] 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.

[0115] 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 cycle of the cell DRX, and the second uplink information can be transmitted in the first time period of the first cycle of the cell DRX, or in other words, the transmission of the first uplink information is affected by the cell DRX configuration, and the transmission of the second uplink information is not affected by the cell DRX configuration.

[0116] 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 overlap in the time domain, or the first uplink information and the second uplink information need to be transmitted in one time slot. It can be considered that the first uplink information and the second uplink information meet the multiplexing conditions.

[0117] The transmission resource of the first uplink information or the second uplink information can be understood as a resource configured for the first uplink information or the second uplink information. Or a resource used to transmit the first uplink information or a resource used to transmit the second uplink information. Or, a resource that can be used to transmit the first uplink information or a resource that can be used to transmit the second uplink information. That is, the first uplink information or the second uplink information has not been sent on the configured resource.

[0118] The transmission resources include time domain resources and frequency domain resources.

[0119] In one possible manner, the time domain resource of the first uplink information is within the first time period. Fig.10 As shown in (a), the starting position and the ending position of the time domain resources of the first uplink information are both within the first time period.

[0120] In another possible manner, part of the time domain resource of the first uplink information is within the first time period. Fig.10As shown in (b) of FIG. 1 , the starting position of the time domain resource of the first uplink information is within the first time period, but the ending position of the time domain resource of the first uplink information is not within the first time period. Fig.10 As shown in (c), the end position of the time domain resource of the first uplink information is within the first time period, but the start position of the time domain resource of the first uplink information is not within the first time period.

[0121] If the starting position or the ending position of the time domain resource overlaps with the first time period, it can be considered that the starting position or the ending position of the time domain resource is within the first time period. Fig.10 As shown in (d) in FIG. 1 , the end position of the time domain resource of the first uplink information is the same as the start position of the first time period; or Fig.10 As shown in (e), 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, and the time domain resource of the first uplink information is regarded as being within the first time period.

[0122] 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 UCI or one PUSCH among the one or more UCIs or PUSCHs overlap with the first time period, the transmission resources of the first uplink information are deemed to overlap with the first time period.

[0123] 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.

[0124] 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 transmitted in the first time period of the first cycle of DRX, the terminal needs to determine the specific content of transmitting the UCI.

[0125] In the above case, the first uplink information may be determined as follows:

[0126] 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.

[0127] 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.

[0128] The third uplink information is information obtained by multiplexing the first uplink information and the second uplink information.

[0129] The replacement statement here also applies to the following possibilities, so I will not go into details.

[0130] Optionally, the channel state information CSI obtained in the most recent measurement has two cases:

[0131] Case ①: The last CSI report corresponding to this CSI configuration.

[0132] 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.

[0133] 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, this 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.

[0134] Alternatively, the terminal sets all the bits of the P / SP-CSI to 0 or all to 1. That is, the terminal fills the bits of the P / SP-CSI with content that does not contain a specific meaning.

[0135] Optionally, the terminal may also fill the bits of the P / SP-CSI with other invalid values, not limited to 0 or 1.

[0136] Possibility 2: When the first uplink information includes an SR, it is determined that the SR included in the first uplink information is a negative SR, that is, regardless of whether there is an uplink transmission (such as data transmission, sending a BFR MAC CE, etc.) requirement, 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.

[0137] 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 to perform 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 method can ensure the stability of UCI multiplexing.

[0138] 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.

[0139] For example, for the SR associated with LCH, if there is an uplink transmission requirement, a positive SR is sent; if not, a negative SR is sent.

[0140] Possibility 3: When the first uplink information includes HARQ-ACK information corresponding to the SPS PDSCH, it is determined that the HARQ-ACK information included in the first uplink information is NACK. In other words, 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 NACK.

[0141] Alternatively, the content of the HARQ-ACK information corresponding to the SPS PDSCH is determined according to the actual transmission situation of the SPS, for example:

[0142] When the terminal correctly decodes the SPS PDSCH, an ACK is generated;

[0143] When the terminal does not correctly decode the SPS PDSCH, a NACK is generated.

[0144] Alternatively, the terminal determines the HARQ-ACK information corresponding to the SPS PDSCH according to the DTX configuration. For example:

[0145] Before the moment when 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, and the second indication information indicates that the terminal should not transmit the SPS PDSCH in the second time period of the second cycle.

[0146] 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;

[0147] 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 situation 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.

[0148] The second cycle and the second time period belong to the configuration content of DTX. In other words, the cycle and the inactive period belong to the configuration information of DTX. The DTX is at the cell level. That is, the DTX is cell DTX. In other words, the replacement name of DTX is CellDTX.

[0149] 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 and improve communication reliability.

[0150] 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.

[0151] 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.

[0152] The third uplink information may include content of the first uplink information and content of the second uplink information.

[0153] It should be understood that the content of the first uplink information determined in 920 may be in the third uplink information or may not be 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, reference can be made to the multiplexing method in the protocol, which will not be described in detail.

[0154] For example, the first uplink information is SR, the second uplink information is DG HARQ-ACK, the transmission resource associated with SR is PUCCH format (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.

[0155] 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 separately and the transmission resource of the first uplink information overlaps with the first time period, the terminal does not send the first uplink information.

[0156] 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 send the specific content of the first uplink signal, and the terminal and the base station have the same understanding of the multiplexing rules of UCI. This avoids the problem that 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), the base station cannot correctly receive the UCI and PUSCH sent by the terminal, thus avoiding affecting communication and improving communication reliability.
