Description
1 / 61 “SIGNAL TRANSMISSION METHOD, RELATED DEVICE, COMPUTER-READABLE STORAGE MEDIA AND SYSTEM” TECHNICAL FIELD
[0001] This application relates to the field of wireless communication technologies and, in particular, to a method of signal transmission, a related apparatus and a system. FUNDAMENTALS
[0002] In an LTE-A system, as shown in FIG. 1, a process from a moment when a terminal device does not have a resource to be scheduled to a moment when the terminal device sends an uplink channel may include: the UE waits a moment to send a scheduling request (SR), and sends the SR; an eNB receives the SR and generates a scheduling grant, and sends the scheduling grant; the UE receives the scheduling grant and sends an uplink channel; and if a volume of UE data is not sent completely, the UE must additionally wait for a subsequent scheduling grant.
[0003] In the LTE-A system, as shown in FIG. 2, if a Hybrid Automatic Repeat reQuest (HARQ) subframe in PUCCH 3 / PUCCH 4 / PUCCH 5 format used by the terminal device and an SR subframe configured by a higher layer for the terminal are the same subframe, there is one scheduling request bit. Otherwise, if they are not the same subframe, there are zero scheduling request bits. One scheduling request bit is added after consecutive HARQ bits. Specifically, when a bit state is 1, this indicates a positive scheduling request (positive SR), and a positive scheduling request indicates that there is currently uplink data to the terminal or a network device currently needs to allocate a resource used for transmission to the terminal.When the bit state of the bit is 0, this indicates a negative scheduling request (negative SR), and the negative scheduling request indicates that there is currently no uplink data to the terminal, or there is currently no need to allocate a resource used for transmission to the terminal. Petition 870260067112, dated 07 / 07 / 2026, page 10 / 83 2 / 61
[0004] In a fifth-generation (NR) mobile radio technology system, there is a plurality of service types, and the plurality of service types corresponds to different service requirements. For example, uRLLC requires short latency and high reliability to ensure a specific and successful transmission within 1 ms; eMBB requires high spectral effectiveness but no latency requirement; and mMTC requires periodic transmission at low power. For different services, the terminal device needs to request resources with different attributes (Numerology / TTI) to meet the service requirements of the different services.
[0005] However, a scaling request bit in LTE-A does not support a multi-service scenario in the future of 5G, and this problem needs to be resolved urgently now. SUMMARY
[0006] This application provides a signal transmission method, a related apparatus, a chip, a computer-readable storage medium, and a system, so that a plurality of scheduling request configurations can be supported, thus adapting to a multi-service scenario in a future communications system.
[0007] According to a first aspect, this application provides a method of signal transmission, which is applied to one side of the terminal device. The method includes: generating, by a terminal device, a first bit and a hybrid auto-repeat request bit; and sending the hybrid auto-repeat request bit and the first bit in a unit of time, where the first bit is used to indicate a scheduling request associated with a first scheduling request configuration and the first scheduling request configuration is at least one among a plurality of scheduling request configurations.
[0008] According to a second aspect, this request provides a signal transmission method, which is applied to one side of the network device. The method includes: receiving, by a network device, a hybrid auto-repeat request bit and a first bit from a terminal device in a unit of time; and determining, based on the first bit, a scheduling request associated with a first scheduling request configuration, where the first bit is used to indicate the Petition 870260067112, dated 07 / 07 / 2026, page 11 / 83 3 / 61 escalation request associated with the first escalation request configuration and the first escalation request configuration is at least one of a plurality of escalation request configurations.
[0009] A plurality of scheduling request configurations can be supported by implementing the methods described in the first and second aspects, in order to adapt to a multi-service scenario in a future communications system.
[0010] In the methods described in the first aspect and the second aspect, the first bit is an SR bit. A scheduling request configuration is referred to as an SR configuration (i.e., SR setting) for brevity below.
[0011] With reference to the first aspect or the second aspect, several ways of defining a quantity of the plurality of SR configurations are described below.
[0012] (1) In method 1, the quantity of SR configuration plurality is equal to a quantity of all SR configurations. To be specific, the SR configuration plurality can be all SR configurations dynamically configured by the network device for the terminal, or it can be all SR configurations configured by the network device for the terminal using higher-layer signaling, or it can be all SR configurations configured by another terminal device for the terminal.
[0013] In method 1, the effectiveness in reporting, by the terminal device, SRs associated with all SR configurations can be improved.
[0014] (2) In method 2, the quantity of SR configuration plurality is equal to a quantity of SR configurations in the unit of time. To be specific, the SR configuration plurality can be the SR configurations in the unit of time that are dynamically configured by the network device for the terminal, or it can be the SR configurations in the unit of time that are configured by the network device for the terminal using higher-layer signaling, or it can be the SR configurations in the unit of time that are configured by another terminal for the terminal.
[0015] In method 2, only the SRs associated with the SR configurations Petition 870260067112, dated 07 / 07 / 2026, page 12 / 83 4 / 61 actually configured for the terminal in the time unit are reported, in order to reduce SR bit overheads.
[0016] (3) In method 3, the quantity of SR configuration plurality is equal to a quantity of SR configurations in a plurality of time units. To be specific, the plurality of SR configurations can be the SR configurations that are dynamically configured by the network device for the terminal and that are in a plurality of time units, or it can be the SR configurations that are configured by the network device for the terminal using upper-layer signaling and that are in a plurality of time units, or it can be the SR configurations that are configured by another terminal for the terminal and that are in a plurality of time units. The plurality of time units includes a time unit in which the terminal sends the hybrid auto-repeat request bit and the first bit.
[0017] In method 3, only the SRs associated with the SR configurations that are actually configured for the terminal and that are in a plurality of time units are reported, in order to reduce SR bit overheads.
[0018] (4) In method 4, the plurality of SR configurations is equal to the number of SR configurations that are associated with the same uplink control channel attribute and that are of one or more time units. To be specific, the plurality of SR configurations may be the SR configurations that are dynamically configured by the network device for the terminal and that are of one or more time units and associated with the same uplink control channel attribute, or it may be the SR configurations that are configured by the network device for the terminal using upper-layer signaling and that are of one or more time units and associated with the same uplink control channel attribute, or it may be the SR configurations that are configured by another terminal for the terminal and that are of one or more time units and associated with the same uplink control channel attribute.
[0019] In method 4, the SR settings associated with different uplink control channel attributes can be reported. Petition 870260067112, dated 07 / 07 / 2026, p. 13 / 83 5 / 61 distinctly, with greater flexibility. SR configurations are reported for different uplink control channel attributes, in order to reduce SR bit overheads.
[0020] With reference to the first aspect or the second aspect, the following describes SR bit design solutions provided in this request.
[0021] Solution 1: A bit in the SR bit (i.e., the first bit) is used to indicate a scheduling request associated with an SR configuration in at least one SR configuration (i.e., the first SR configuration). It can be understood that a first SR configuration corresponds to a bit in the SR bit. Specifically, an SR configuration corresponds to a bit in the SR bit. In this case, an OSR quantity of SR bits is equal to a quantity of the plurality of SR configurations (i.e., the plurality of SR configurations mentioned in the principles of the prior invention) configured for the terminal. This is one way in which the OSR quantity of SR bits is related to the quantity of the plurality of SR configurations.
[0022] Specifically, a correspondence between an SR setting and a bit in the SR bit can be dynamically configured by the network device, or it can be configured by the network device using higher-layer signaling. The correspondence can include the SR setting B, and the bit B corresponding, respectively, to the SR setting B. In this way, the terminal device can determine, based on the correspondence, each bit corresponding to each SR setting of at least one SR setting (that is, the first SR setting) in the SR bits. In this report, B is a positive integer. In this application, the correspondence configured by the network device or configured using higher-layer signaling can be referred to as a first correspondence.
[0023] This request is not limited to an SR configuration corresponding to one bit in the SR bit. In solution 1, an SR configuration may alternatively correspond to a plurality of bits in the SR bits. In other words, a plurality of bits may be used to indicate an SR associated with an SR configuration. In this case, the OSR quantity of SR bits is equal to an integer multiple of the quantity of SR configurations (i.e., the plurality of SR configurations mentioned in the principles of the prior invention) configured by the network device for the terminal. This is another way in which Petition 870260067112, dated 07 / 07 / 2026, p. 14 / 83 6 / 61 The OSR quantity of the SR bit is related to the SR configuration quantity set by the network device for the terminal.
[0024] The technical effects of solution 1 are as follows: A plurality of SRs can be reported, and a plurality of SRs associated with different SR configurations can be flexibly implemented.
[0025] Solution 2: A bit state of an SR bit (i.e., a first bit) is used to indicate a scheduling request associated with at least one SR setting (i.e., the first SR setting). The SR (positive SR or negative SR) associated with the first SR setting corresponds to the state of the SR bit.
[0026] Optionally, a first SR bit state is used to indicate that the SR associated with the first SR setting is a negative SR. Optionally, at least one SR bit state other than the first state is used to indicate that the SR associated with the first SR setting is a positive SR. Optionally, no SR bit state other than the first state is used to indicate that any of the SRs associated with the first SR setting is a negative SR.
[0027] Specifically, a match between an SR and an SR bit state can be configured by the network device or configured using higher-layer signaling. The match configured by the network device or configured using higher-layer signaling can include SRs associated with P SR settings, and Q states corresponding to SRs associated with P SR settings. In this way, the terminal can determine, based on the match, a state corresponding to an SR associated with at least one SR setting (i.e., the first SR setting). In this report, Q > 3, Q is a positive integer, P > 2, and P is a positive integer. In this request, the match configured by the network device or configured using higher-layer signaling can be referred to as a second match.
[0028] In solution 2, the OSR quantity of SR bits can be: OSR = ceil(log2 (1 + Nconfiguration)), where Nconfiguration represents the quantity of SR configurations (i.e., the plurality of SR configurations mentioned in the principles of the prior invention) configured for the terminal, and ceil represents rounding up to the next integer. This is another Petition 870260067112, dated 07 / 07 / 2026, p. 15 / 83 7 / 61 The way in which the OSR quantity of SR bits is related to the quantity of SR settings configured by the network device for the terminal.
[0029] Optionally, an index of an SR configuration associated with a positive SR can be used as a maximum value, and the SRs associated with the SR configurations whose indices are less than the maximum value are all positive SRs. In this way, the terminal device can indicate, based on only one state of an SR bit corresponding to this positive SR, the positive SRs associated with a plurality of SR configurations.
[0030] For example, consider that a state of the SR bits is “100”, used to indicate a positive SR associated with an SR #3 configuration. In this case, the index “3” of the SR #3 configuration is used as a maximum value, and the SRs respectively associated with an SR #2 configuration, an SR #1 configuration, and an SR #0 configuration whose indices are less than “3” are all positive SRs. The example is merely used to explain this request and should not be interpreted as any limitation.
[0031] Optionally, an index of an SR configuration associated with a positive SR can be used as a minimum value, and the SRs associated with the SR configurations whose indices are greater than the minimum value are all positive SRs. In this way, the terminal device can indicate, based on only one state of an SR bit corresponding to this positive SR, the positive SRs associated with a plurality of SR configurations.
[0032] For example, consider that a state of the SR bits is “001”, used to indicate a positive SR associated with an SR #1 configuration. In this case, the index “1” of the SR #1 configuration is used as a minimum value, and the SRs respectively associated with an SR #2 configuration and an SR #3 configuration whose indices are greater than “1” are all positive SRs. The example is merely used to explain this request, and should not be interpreted as any limitation.
[0033] The technical effects of solution 2 are as follows: Each SR associated with each SR configuration of at least one SR configuration (i.e., the first SR configuration) is indicated using a relatively small number of bits, so that the amount of information carried in an uplink control channel can be reduced, thereby increasing the successful transmission rate of the control channel. Petition 870260067112, dated 07 / 07 / 2026, page 16 / 83 8 / 61 ascending link.
[0034] With reference to the first aspect or the second aspect, in some optional implementations, the number of HARQ bits sent along with the SR bit is greater than or equal to X, X > 2, and X is a positive integer. This avoids affecting a successful transmission rate for a small number of HARQ bits. This is because the reliability of the HARQ transmission design increases as the number of HARQ bits increases. In other words, when the number of HARQ bits is relatively small, it is not appropriate to add a plurality of SR bits after a HARQ bit.
[0035] With reference to the first aspect or the second aspect, in some optional implementations, the length of a current time unit is greater than or equal to Y symbols, Y > 1, and Y is a positive integer. This avoids affecting the successful transmission rate of an uplink control channel in a time unit of a short length. This is because the transmission power of an uplink control channel in a current time unit increases as the time length of a current time domain resource increases, bringing greater reliability. In other words, when the time length of the current time unit is relatively small, it is not suitable for the uplink control channel in the current time unit to carry a plurality of SR bits.

[0068] The terms used in the modalities of this application are intended only to explain the specific modalities of this application, but are not intended to limit this application.
[0069] FIG. 3 shows a wireless communications system in this application. The wireless communications system may be a Global System of Mobile Communication (GSM), a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access Wireless (WCDMA) system, a General Packet Radio Service (GPRS) system, a Universal Mobile Telecommunications System (UMTS), or a Long Term Evolution (LTE) system; or it may be a future evolved fifth-generation mobile communications system (5G), a new radio (NR) system, a machine-to-machine (M2M) communications system, or the like. As shown in FIG.3. The wireless communications system 100 may include: one or more network devices 101, one or more terminal devices 103 and a network core 115.
[0070] Terminal device 103 may also be referred to as User Equipment (UE), an access terminal, a Petition 870260067112, dated 07 / 07 / 2026, p. 22 / 83 14 / 61 subscriber unit, subscriber station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communications device, user agent or user device.Terminal device 103 may be a station (STATION, ST) in a wireless local area network (WLAN), a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a wireless local loop station (WLL), a Personal Digital Assistant (PDA) device, a portable device or a computing device having a wireless communications function, another processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device 103 in a next-generation communications system, such as a fifth-generation (5G) communications network, a terminal device 103 in a future evolved Public Land Mobile Network (PLMN), a terminal device 103 in a New Radio (NR) communications system, or similar.
[0071] By way of example, but not limitation, in this embodiment of the present invention, the terminal device 103 may be a wearable device. The wearable device may also be referred to as a smart wearable device. Smart wearable device is a collective name for wearable devices, such as eyeglasses, gloves, watches, clothing and shoes, obtained by intelligent design and development in everyday clothing using wearable technology. The wearable device is a portable device that is worn directly on the human body or is integrated into the user's clothing or ornaments. The wearable device is not merely a hardware device, but additionally implements a powerful function through software support, data exchange and cloud-based interaction.In a broad sense, a smart wearable device includes a device that provides a complete function, has a large size, and can implement all or some functions without relying on a smartphone, for example, a smartwatch or smart glasses; and includes a device that focuses only on a specific type of application and needs to be used in combination with another device, such as a smartphone, for example, several. Petition 870260067112, dated 07 / 07 / 2026, page 23 / 83 15 / 61 smart bands and smart jewelry used for vital sign monitoring.
[0072] In addition, the 101 network device may be a device configured to communicate with a mobile device on a network. The 101 network device may be an Access Point (AP) in a WLAN, a Base Transceiver Station (BTS) in a GSM or CDMA system, a NodeB (NB) in a WCDMA system, an Evolutional NodeB (eNB or eNodeB) in an LTE system, a relay station or access point, a vehicle-mounted device, a wearable device, a 101 network device in a future 5G network, a 101 network device in a future evolved PLMN network, a new generation NodeB (gNodeB) in an NR system, or similar.
[0073] Furthermore, in this embodiment of the present invention, the network device 101 provides a cell with a service, and the terminal device 103 communicates with the network device 101 using a transmission resource (for example, a frequency domain resource, or referred to as a frequency spectrum resource) used by the cell. The cell may be a cell corresponding to the network device 101 (for example, a base station). The cell may belong to a macro base station, or a base station corresponding to a small cell. The small cell in this report may include: a metro cell, a micro cell, a pico cell, a femto cell, or similar. These small cells have a small coverage area and low transmission power, and are suitable for providing a high-rate data transmission service.
[0074] Furthermore, in an LTE or NR system, a plurality of cells can work simultaneously on the same frequency on a carrier, and the concept of "carrier" can be considered equivalent to the concept of "cell" in some special scenarios. For example, in a Carrier Aggregation (CA) scenario, when a secondary carrier is configured for UE, the carrier configuration information includes both a carrier index of the secondary carrier and a Cell Identity (Cell ID) of the operating secondary cell. Petition 870260067112, dated 07 / 07 / 2026, page 24 / 83 16 / 61 on the secondary carrier. In this case, the concept of "carrier" can be considered equivalent to the concept of "cell". For example, EU access to a carrier is equivalent to EU access to a cell.
[0075] In this embodiment of the present invention, the network device 101 (or the terminal 103) can operate in a licensed frequency band or a license-free frequency band.
[0076] It should be noted that the 100 wireless communications system shown in FIG. 3 is merely intended to describe the technical solutions in this application more clearly, but should not be interpreted as any limitation in this application. A person skilled in the art may be aware that, with the evolution of network architectures and the emergence of new service scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

These components may be connected using a bus 204 or otherwise, and are connected, for example, using a bus in FIG. 4.
[0078] The communications interface 203 can be used by the terminal device 200 to communicate with another communications device, for example, a network device. Specifically, the network device can be a network device 300 shown in FIG. 5. Specifically, the communications interface 203 can be a Long Term Evolution (LTE) (4G) communications interface, or it can be a 5G communications interface or a future new radio communications interface. The communications interface 203 is not limited to a wireless communications interface. The terminal device 200 can be additionally equipped with a wired communications interface 203, for example, a Local Access Network (LAN) interface.

[0095] Based on the modes corresponding to the previous wireless communication system 100, the terminal device 200, and the network device 300, respectively, this application provides a signal transmission method, as described in detail below.
[0096] First, to help understand this application, the following describes the basic concepts in this application.
[0097] (1) Escalation request configuration (escalation request configuration, briefly referred to as an SR configuration below)
[0098] An SR configuration can be dynamically configured by a network device to a terminal, or it can be configured by a network device to a terminal using higher-layer signaling. Higher-layer signaling can be sent by a higher protocol layer. The higher protocol layer is at least one protocol layer in all protocol layers above a physical layer. Specifically, the higher protocol layer can be at least one of the following protocol layers: a Medium Access Control (MAC) layer, a Radio Link Control (RLC) layer, a data convergence protocol of Petition 870260067112, dated 07 / 07 / 2026, page 30 / 83 22 / 61 packet (Packet Data Convergence Protocol, PDCP), a radio resource control layer (Radio Resource Control, RRC), a non-access stratum layer (Non-Access Stratum, NAS), and the like.
[0099] It can be understood that an SR configuration is associated with a first escalation request in at least one of the following ways:
[0100] 1. The SR setting can be used to indicate a time-domain location and / or a frequency-domain location of the first scheduling request. For example, the SR setting indicates a time period in which the first scheduling request can be sent; in other words, a time-domain location corresponding to the time period is a time-domain location in which the first scheduling request can be sent. The SR setting indicates a subcarrier spacing in which the first scheduling request can be sent; in other words, a subcarrier size corresponding to the subcarrier spacing is a subcarrier in which the first scheduling request can be sent.
[0101] Table 1-1, Table 1-2 and Table 1-3 show examples of three SR configurations. Table 1-1 SR Configuration Index Number Time Domain Location SR Configuration #0 Once every 2 ms SR Configuration #1 Once every seven symbols SR Configuration #2 Once per slot Table 1-2 SR Configuration Index Number Frequency Domain Location SR Configuration #0 Physical Resource Block 1 SR Configuration #1 Physical Resource Block 2 SR Configuration #2 Physical Resource Block 1 Table 1-3 Petition 870260067112, dated 07 / 07 / 2026, page 31 / 83 23 / 61 SR configuration index number Time domain location Frequency domain location SR configuration #0 Once every 2 ms Physical resource block 1 SR configuration #1 Once every seven symbols Physical resource block 2 SR configuration #2 Once every symbol Physical resource block 3
[0102] It can be learned that, a plurality of SR configurations It can indicate the same time domain location, or it can indicate different time domain locations; and a plurality of SR configurations can indicate the same frequency domain location, or it can indicate different frequency domain locations.
[0103] 2. The SR configuration can be used to indicate a time unit length occupied by an uplink control channel carrying the first scheduling request and / or a subcarrier spacing size occupied by an uplink control channel carrying the first scheduling request. For example, the SR configuration indicates that a time unit length occupied by an uplink control channel carrying the first scheduling request is two symbols; in other words, the first scheduling request can be sent on a two-symbol uplink control channel.
[0104] Table 2-1, Table 2-2 and Table 2-3 show examples of three SR configurations. Table 2-1 SR configuration index number. Length of a time unit occupied by an uplink control channel. SR configuration #0: 1 ms subframe. SR configuration #1: 7 symbols. SR configuration #2: 1 slot. Table 2-2 Petition 870260067112, dated 07 / 07 / 2026, page 32 / 83 24 / 61 SR Configuration Index Number Size of a subcarrier spacing occupied by an uplink control channel SR configuration #0 15 kHz SR configuration #1 60 kHz SR configuration #2 30 kHz Table 2-3 SR configuration index number Length of a time unit occupied by an uplink control channel Size of a subcarrier spacing occupied by an uplink control channel SR configuration #0 1 ms subframe 15 kHz SR configuration #1 7 symbols 60 kHz SR configuration #2 1 symbol 30 kHz
[0105] It can be learned that a plurality of SR configurations can indicate the same length of a time unit occupied by an uplink control channel, or it can indicate different lengths of a time unit occupied by an uplink control channel; and a plurality of SR configurations can indicate the same size of a subcarrier spacing occupied by an uplink control channel, or it can indicate different sizes of a subcarrier spacing occupied by an uplink control channel.
[0106] 3. The SR configuration can be used to indicate an attribute (Numerology / TTI / logical channel) of a resource requested in the first scheduling request. Different SR configurations are for different services, due to the fact that a requirement for a resource attribute varies according to different services. Specifically, an attribute of a frequency domain resource requested in the first scheduling request is a Petition 870260067112, dated 07 / 07 / 2026, page 33 / 83 25 / 61 first numerology (for example, a first subcarrier spacing (subcarrier spacing, SCS)), and / or an attribute of a time-domain resource requested in the first scheduling request is a first time unit, and / or a logical channel requested in the first scheduling request is a first logical channel, and / or a priority of a logical channel requested in the first scheduling request is a second priority.
[0107] Table 3-1, Table 3-2, Table 3-3 and Table 3-4 show examples of three SR configurations. Table 3-1 SR configuration index number. Attribute of a requested time domain resource (time unit). SR configuration #0 1 ms SR configuration #1 2 symbols SR configuration #2 1 slot Table 3-2 SR Configuration Index Number Attribute of a requested time domain resource (time unit) Service SR Configuration #0 1 ms Service #0 SR Configuration #1 2 symbols Service #1 SR Configuration #2 1 slot Service #2 Table 3-3 SR configuration index number. Attribute of a requested time domain resource (time unit). Attribute (Numerology) of a requested frequency domain resource. SR configuration #0 1 ms 15 kHz. SR configuration #1 2 symbols 60 kHz. Petition 870260067112, dated 07 / 07 / 2026, page 34 / 83 26 / 61 SR configuration index number. Attribute of a requested time domain resource (time unit). Attribute (Numerology) of a requested frequency domain resource. SR configuration #2 1 slot 30 kHz Table 3-4 SR Configuration Index Number Attribute of a requested time domain resource (time unit) Service SR Configuration #0 1 ms Service #0 SR Configuration #1 2 symbols Service #1 SR Configuration #2 1 slot Service #2
[0108] It can be learned that a plurality of SR configurations can indicate the same attribute of a requested time-domain resource, or it can indicate different attributes of a requested time-domain resource; and a plurality of SR configurations can indicate the same attribute of a requested frequency-domain resource, or it can indicate different attributes of a requested frequency-domain resource.
[0109] It should be noted that the three previous SR configurations respectively correspond to requirements for different services. It can be learned that if a service requires a relatively short time, an SR configuration whose requested time unit is relatively small can be configured for a terminal; or if a service requires a relatively long time, an SR configuration whose requested time unit is relatively large can be configured for a terminal.
[0110] The foregoing are merely used to explain the principles of the invention in this application, and may not be construed as any limitation.
[0111] (2) Scheduling request bit (scheduling request bit, briefly referred to as an SR bit below) Petition 870260067112, dated 07 / 07 / 2026, page 35 / 83 27 / 61
[0112] The SR bit is used to indicate an SR reported by a terminal device, and specifically indicates an SR associated with a specific SR configuration and indicates whether the reported SR associated with the SR configuration is a positive SR or a negative SR.
[0113] There may be one or more SR bits. In this application, the number of SR bits is greater than or equal to 2. The number of SR bits may be related to the number of SR settings.
[0114] Optionally, in this application, an SR bit and a HARQ bit are carried on the same uplink control channel.
[0115] Specifically, a terminal can determine a number of SR bits based on a number of SR configurations. Optionally, the number of SR bits can be equal to the number of SR configurations. Optionally, the number of SR bits can be equal to: ceil(log2 (1+Nconfiguration)), where Nconfiguration represents the number of SR configurations, and ceil represents rounding up to the nearest integer. For a correlation between the number of SR bits and the number of SR configurations, refer to subsequent modes 1 and 2. The details are not described again in this report.
[0116] For example, an SR #0 configuration and an SR #1 configuration in tables 3 and 4 are considered to be SR configurations in a slot #0.
[0117] When slot #0 arrives, the terminal can indicate, using two bits, SRs associated with the SR configurations in slot #0 that are configured for the terminal. One bit (e.g., a most significant bit) is used to indicate whether an SR associated with SR configuration #0 is a positive SR or a negative SR. The other bit (e.g., a least significant bit) is used to indicate whether an SR associated with SR configuration #1 is a positive SR or a negative SR. In other words, both bits are SR bits, and one bit corresponds to an SR configuration.
[0118] When slot #0 arrives, the terminal can indicate, still using two bits, SRs associated with the SR configurations in slot #0 that are configured for the terminal. When both bits are “01”, this indicates that the terminal device reports, in slot #0, only a positive SR associated with SR configuration #1 and does not report an SR associated with SR configuration #0; or when both bits are “10”, this indicates that the terminal device reports, in slot Petition 870260067112, dated 07 / 07 / 2026, p. 36 / 83 28 / 61 #0, only one positive SR associated with configuration SR #0 and does not report an SR associated with configuration SR #1; or when both bits are “00”, this indicates that the terminal device reports, in slot #0, both a negative SR associated with configuration SR #0 and a negative SR associated with configuration SR #1.
[0119] (3) Time unit
[0120] In this request, the length of a time unit can be set to any value, and is not limited in this report.
[0121] For example, a time unit may include one or more subframes.
[0122] Alternatively, a unit of time may include one or more slots.
[0123] Alternatively, a time unit may include one or more mini-slots.
[0124] Alternatively, a unit of time may include one or more symbols.
[0125] Alternatively, a unit of time may include one or more transmission time intervals (TTI).
[0126] Alternatively, a unit of time may include one or more short transmission time intervals (sTTI).
[0127] Alternatively, a time unit may correspond to a time mode. For example, a first time mode is a transmission time interval of two symbols or three symbols, and a second time mode is a transmission time interval of seven symbols.
[0128] The mini-slot includes one or more symbols, and is less than or equal to a slot. In this report, the mini-slot may be a mini-slot in a system with a subcarrier spacing of 60 kHz, or it may be a mini-slot in a system with a subcarrier spacing of 15 kHz, and this is not limited to the embodiments of the present invention.
[0129] The slot includes one or more symbols. In this report, the slot may be a slot in a system with a subcarrier spacing of 60 kHz, or it may be a slot in a system with a subcarrier spacing of 15 kHz, and this is not limited to the embodiments of the present invention.
[0130] TTI is a parameter commonly used in a system of Petition 870260067112, dated 07 / 07 / 2026, page 37 / 83 29 / 61 current communications (e.g., an LTE system), and is a scheduling unit used for scheduling data transmission on a radio link. In the state of the art, it is generally considered that 1 TTI = 1 ms. In other words, a TTI is a subframe, or a two-slot size. TTI is a basic managed time unit in radio resource management (e.g., scheduling).
[0131] (4) Hybrid Automatic Repeat reQuest (HARQ) bit, briefly referred to as a HARQ bit below
[0132] A HARQ bit is used to return a decoding result of one or more downlink data blocks by a terminal and can be a positive ACK acknowledgment or a negative ACK acknowledgment. ACK indicates that the terminal has correctly performed the decoding. NACK indicates that an error has occurred during decoding by the terminal. Specifically, the terminal can return the HARQ bit to a network device, or the terminal can return the HARQ bit to another terminal. Furthermore, if the terminal returns a negative acknowledgment, a device receiving the HARQ bit retransmits data indicating that an error occurred during decoding by the terminal, to help the terminal correctly receive the downlink data.
[0133] The previous example is merely used to explain this request, and should be interpreted without any limitation. The correlation between a quantity of SR bits and a quantity of SR settings configured for a terminal is described in detail in a subsequent embodiment, and the details are not described again in this report.
[0134] Secondly, the main principles of the invention of this application may include: selecting, by a terminal device, at least one SR configuration from a plurality of SR configurations; and then sending, by the terminal, a hybrid auto-repeat request bit and an SR bit in a unit of time, where the SR bit is used to indicate each SR associated with each SR configuration of at least one SR configuration. Correspondingly, a network device can receive the HARQ bit and the SR bit from the terminal, and determine, based on the SR bit, an SR reported by the terminal. In this way, the terminal device can indicate that the configuration Petition 870260067112, dated 07 / 07 / 2026, page 38 / 83 30 / 61 The SR reported by the terminal device is associated with a positive SR and / or the SR configuration reported by the terminal device is associated with a negative SR. In this application, a plurality of SR configurations can be supported, in order to adapt to a multi-service scenario in the future of 5G.
[0135] In this application, the SR bit can be referred to as a first bit, and the preceding, at least one SR setting can be referred to as a first SR setting. The preceding, at least one SR setting can be an SR setting, configured by the network device for the terminal device, in a current time unit (i.e., a time unit). In this report, the current time unit can be a time unit in which the terminal device is ready to send the HARQ bit and the SR bit. In this application, a positive SR indicates to the terminal device that there is currently uplink data to the terminal, or the network device currently needs to allocate a resource used for transmission to the terminal. The resource used for transmission can be scheduled by the network device or can be predefined.A negative SR indicates to the terminal device that there is currently no uplink data to the terminal device, or there is currently no need to allocate a resource used for transmission to the terminal. It can be understood that if a receiving device receives only a positive SR associated with an SR configuration, the receiving device can consider that SR configurations different from this SR configuration in at least one SR configuration are all negative SRs. The receiving device can be a network device or a terminal.
[0136] In this request, the network device can additionally configure a time unit in which the plurality of SR configurations is located. In this report, a time unit in which an SR configuration is located is a time unit in which the terminal device can report an SR associated with the SR configuration. In other words, if an SR configuration exists in a time unit, this indicates that the terminal device can report, in this time unit, an SR associated with this SR configuration. It can be understood that an SR configuration configured for the terminal can indicate the time unit. Petition 870260067112, dated 07 / 07 / 2026, p. 39 / 83 31 / 61
[0137] FIG. 6 shows an example of a time unit in which three SR configurations (an SR configuration #0, an SR configuration #1, and an SR configuration #2) configured by the network device are located. As shown in FIG. 6, a time unit in which the SR configuration #0 is located is a symbol #0, a symbol #2, a symbol #4, and a symbol #6. This indicates that the terminal device can send, in all four symbols, an SR associated with the SR configuration #0. The example is merely used to explain the modalities of this request and should not be interpreted as any limitation.
[0138] It can be understood that, although a time unit in which the terminal device reports an SR is configured by the network device, or configured using higher-layer signaling, or configured by the terminal device, generating an SR is a behavior of the terminal device; therefore, the network device only knows that an SR associated with a specific SR configuration may exist in a specific time unit, but does not know that the SR associated with the SR configuration is actually reported by the terminal device in this specific time unit. For the network device to know that the SR configuration actually reported by the terminal device in this specific time unit is associated with the SR, the terminal device needs to send an SR bit to the network device.
[0139] For example, in the example shown in FIG. 6, the terminal device may determine, according to a real requirement, to report, in symbol #0, only the SR associated with configuration SR #0 and not report an SR associated with configuration SR #1. The terminal device sends two SR bits “10” to the network device, so that the network device can know, based on the two SR bits “10”, that the terminal device actually reports, in symbol #0, only the SR associated with configuration SR #0 and does not report the SR associated with configuration SR #1.
[0140] For example, in the example shown in FIG. 6, the terminal device can determine, according to a real requirement, report, in symbol #0, the SR associated with configuration SR #0 and an SR associated with configuration SR #1. A most significant bit “1” is used to indicate whether the SR associated with configuration SR #0 is a positive SR or a negative SR, and a least significant bit “0” is used to indicate whether the SR associated with configuration SR #1 is Petition 870260067112, dated 07 / 07 / 2026, p. 40 / 83 32 / 61 a positive SR or a negative SR. In this way, the network device can know, based on the two SR bits “10”, that the terminal device actually reports the SR associated with the SR #0 configuration and the SR associated with the SR #1 configuration in symbol #0. The example is merely used to explain this request, and should not be interpreted as any limitation.
[0141] In this application, there may be a correlation between a number of SR bits and a number of SR configuration pluralities configured by the network device for the terminal device. This correlation is specifically described in a subsequent embodiment, and the details are not described again in this report. Optionally, the number of SR configuration pluralities is greater than or equal to 2. First, the following describes various ways in which the number of SR configuration pluralities is defined.
[0142] (1) In method 1, the quantity of SR configuration plurality is equal to a quantity of all SR configurations. In other words, the SR configuration plurality can be all SR configurations dynamically configured by the network device for the terminal, or it can be all SR configurations configured by the network device for the terminal using higher-layer signaling, or it can be all SR configurations configured by another terminal device for the terminal.
[0143] For example, as shown in FIG. 8, all SR configurations configured by the network device for the terminal device are: an SR configuration #0, an SR configuration #1, and an SR configuration #2. In other words, the quantity of all SR configurations configured by the network device for the terminal is 3. It can be learned from FIG. 8 that some SR configurations in all SR configurations can be separately used in each time unit (symbol). A first bit is used to indicate an SR associated with at least one SR configuration in all SR configurations. For example, SR configuration #0 and SR configuration #1 are used in a symbol #0, and the first bit is used to indicate an SR associated with SR configuration #0 and / or SR configuration #1 in all SR configurations; and SR configuration #2 is used in a symbol #1, and the first bit is used to indicate an associated SR Petition 870260067112, dated 07 / 07 / 2026, p. 41 / 83 33 / 61 to SR configuration #2 in all SR configurations. The example is merely used to explain this request, and should not be interpreted as any limitation.
[0144] In method 1, the effectiveness of reporting, by the terminal device, of the SRs associated with all SR configurations can be improved. For example, as shown in FIG. 8, even if a time unit corresponding to SR configuration #2 is at symbol #1 but not at symbol #0, the terminal device can notify the network device at symbol #0 of the SR associated with SR configuration #2, instead of notifying the network device at symbol #1 of the SR associated with SR configuration #2, thus improving effectiveness. The example is merely used to explain this request and should not be interpreted as any limitation.
[0145] (2) In method 2, the quantity of SR configuration plurality is equal to a quantity of SR configurations in the unit of time. To be specific, the SR configuration plurality can be the SR configurations in the unit of time that are dynamically configured by the network device for the terminal, or it can be the SR configurations in the unit of time that are configured by the network device for the terminal using higher-layer signaling, or it can be the SR configurations in the unit of time that are configured by another terminal for the terminal.
[0146] For example, as shown in FIG. 9, the SR configurations on symbol #0 that are configured by the network device for the terminal device are: one SR configuration #0 and one SR configuration #1. In other words, the number of SR configurations on symbol #0 that are configured by the network device for the terminal is 2, and the first bit is used to indicate an SR associated with at least one SR configuration in both SR configuration #0 and SR configuration #1. For another example, as shown in FIG. 9, an SR configuration that is configured by the network device for the terminal device and that is on symbol #1 is an SR configuration #2. In other words, the number of SR configurations on symbol #1 that are configured by the network device for the terminal is 1, and the first bit is used to indicate an SR associated with an SR configuration #2. The examples are merely used to explain this application and should not be interpreted as any limitation. Petition 870260067112, dated 07 / 07 / 2026, page 42 / 83 34 / 61
[0147] In method 2, the SR settings in a time unit that are configured for the terminal may include the SR settings associated with different uplink control channel attributes. For details on an uplink control channel attribute associated with an SR setting, refer to the description of a subsequent method 4. The explanation is not given in this report.
[0148] In method 2, only the SRs associated with the SR configurations in the time unit that are actually configured for the terminal are reported, to reduce SR bit overhead. For example, as shown in FIG. 8, there is an SR configuration #0 and an SR configuration #1 in a symbol #0, and the terminal device can report, using only two bits, an SR associated with SR configuration #0 and an SR associated with SR configuration #1; and there is only an SR configuration #2 in a symbol #1, and the terminal device can report, using only one bit, an SR associated with SR configuration #2. The example is merely used to explain this request, and should not be interpreted as any limitation.
[0149] (3) In method 3, the quantity of SR configuration plurality is equal to a quantity of SR configurations in a plurality of time units. In other words, the plurality of SR configurations can be the SR configurations that are dynamically configured by the network device for the terminal and that are in a plurality of time units, or it can be the SR configurations that are configured by the network device for the terminal using upper-layer signaling and that are in a plurality of time units, or it can be the SR configurations that are configured by another terminal for the terminal and that are in a plurality of time units. The plurality of time units includes a time unit in which the terminal sends the hybrid auto-repeat request bit and the first bit.
[0150] For example, as shown in FIG. 10, the SR settings in a symbol #0 that are configured by the network device for the terminal device are: an SR setting #0 and an SR setting #1; and an SR setting that is configured by the network device for the terminal device and that is in a symbol #1 is an SR setting #2. In other words, the total SR settings that are configured by Petition 870260067112, dated 07 / 07 / 2026, page 43 / 83 35 / 61 network device for the terminal and that are in symbol #0 and in symbol #1: the SR configuration #0, the SR configuration #1 and the SR configuration #2. The number of SR configurations that is configured by the network device for the terminal and that is in symbol #0 and in symbol #1 is 3, and the first bit is used to indicate an SR associated with at least one SR configuration in SR configuration #0, in SR configuration #1 and in SR configuration #2. The example is merely used to explain this request, and should not be interpreted as any limitation.
[0151] In the example shown in FIG. 10, the plurality of time units is consecutive. This application is not limited to this, and the plurality of time units may alternatively be non-consecutive. For example, as shown in FIG. 11, the SR settings on symbol #0 that are configured by the network device for the terminal device are: an SR setting #0 and an SR setting #1; and an SR setting that is configured by the network device for the terminal device and that is on symbol #2 is an SR setting #0. In other words, the total SR settings that are configured by the network device for the terminal on symbol #0 and symbol #2 are: the SR setting #0 and the SR setting #1.The number of SR configurations that is configured by the network device for the terminal and that is in symbol #0 and symbol #2 is 2, and the first bit is used to indicate an SR associated with at least one SR configuration in SR configuration #0 and SR configuration #1. The example is merely used to explain this request and should not be interpreted as any limitation.
[0152] In method 3, the SR settings that are configured for the terminal and that are in a plurality of time units may include the SR settings associated with different uplink control channel attributes. For details on an uplink control channel attribute associated with an SR setting, refer to the description of a subsequent method 4. The explanation is not given in this report.
[0153] In method 3, which is similar to method 2, only the SRs associated with the SR settings that are actually configured for the terminal and that are in a plurality of time units are reported, in order to reduce SR bit overheads.
[0154] (4) In manner 4, the quantity of the plurality of Petition 870260067112, dated 07 / 07 / 2026, p. 44 / 83 36 / 61 SR configurations equals a number of SR configurations that are associated with the same uplink control channel attribute and that are of one or more time units. To be specific, the plurality of SR configurations can be SR configurations that are dynamically configured by the network device for the terminal and that are of one or more time units and associated with the same uplink control channel attribute, or it can be SR configurations that are configured by the network device for the terminal using upper-layer signaling and that are of one or more time units and associated with the same uplink control channel attribute, or it can be SR configurations that are configured by another terminal for the terminal and that are of one or more time units and associated with the same uplink control channel attribute.
[0155] In this report, an uplink control channel attribute associated with an SR configuration is an attribute of an uplink control channel that carries an SR. An attribute of an uplink control channel may include at least one of the following: a length of a time unit occupied by the uplink control channel, or a number of time units occupied by the uplink control channel, or a format of the uplink control channel, or a minimum or maximum number of bits carried by the uplink control channel.
[0156] First, a single unit of time (for example, a unit of time is a symbol) is used as an example.
[0157] For example, as shown in FIG. 12, the SR configurations on a symbol #0 that are configured by the network device for the terminal device are: an SR configuration #0, an SR configuration #1, and an SR configuration #3. The SR configuration #0 and the SR configuration #1 are associated with the same uplink control channel attribute, and the same uplink control channel attribute is a symbol. In other words, a length of a time unit carrying an SR associated with the SR configuration #0 is a symbol, and a length of a time unit carrying an SR associated with the SR configuration #1 is also a symbol. An associated uplink control channel attribute Petition 870260067112, dated 07 / 07 / 2026, page 45 / 83 37 / 61 to the SR #3 configuration is a mini-slot (i.e., four symbols). In other words, a time unit length that carries an SR associated with the SR #3 configuration is four symbols or a mini-slot.
[0158] In the example shown in FIG. 12, from a symbol uplink control channel attribute perspective, the SR settings on symbol #0 that are configured by the network device for the terminal device are SR setting #0 and SR setting #1, and do not include SR setting #3. In other words, the number of SR settings that are configured by the network device for the terminal and that are on symbol #0 and associated with the symbol uplink control channel attribute is 2, and in this case, a first bit is used to indicate an SR associated with at least one SR setting in SR setting #0 and SR setting #1.
[0159] In the example shown in FIG. 12, from the perspective of the uplink control channel attribute of a mini-slot, an SR configuration that is configured by the network device for the terminal device and that is in symbol #0 is the SR configuration #3, and does not include the SR configuration #0 or the SR configuration #1. In other words, the number of SR configurations in symbol #0 that is configured by the network device for the terminal and that is associated with the uplink control channel attribute of a mini-slot is 1, and in this case, the first bit is used to indicate an SR associated with the SR configuration #3.
[0160] The previous example is merely used to explain this request, and should not be interpreted as any limitation.
[0161] Secondly, a plurality of time units (for example, a time unit is a symbol) is used as an example.
[0162] For another example, as shown in FIG. 12, the SR configurations that are configured by the network device for the terminal device and that are in symbol #0 to symbol #3 are: an SR configuration #0, an SR configuration #1, an SR configuration #2, and an SR configuration #3. The SR configuration #0, the SR configuration #1, and the SR configuration #2 are associated with the same uplink control channel attribute, and the same uplink control channel attribute is a symbol. An uplink control channel attribute Petition 870260067112, dated 07 / 07 / 2026, page 46 / 83 38 / 61 ascending associated with the SR #3 configuration is a mini-slot (i.e., four symbols).
[0163] In the example shown in FIG. 12, from a symbol uplink control channel attribute perspective, the SR configurations that are configured by the network device for the terminal device and that are in symbol #0 to symbol #3 are SR configuration #0, SR configuration #1, and SR configuration #2, and do not include SR configuration #3. In other words, a number of SR configurations that is configured by the network device for the terminal and that are in symbol #0 to symbol #3 and associated with the uplink control channel attribute is 3 of a symbol, and in this case, a first bit is used to indicate an SR associated with at least one SR configuration in SR configuration #0, SR configuration #1, and SR configuration #2.
[0164] In the example shown in FIG. 12, from the perspective of the uplink control channel attribute of a mini-slot, an SR configuration that is configured by the network device for the terminal device and that is in symbol #0 to symbol #4 is the SR configuration #3, and does not include the SR configuration #0, the SR configuration #1 and the SR configuration #2. In other words, a quantity of SR configurations that is configured by the network device for the terminal and that is in symbol #0 to symbol #4 and associated with the uplink control channel attribute of a mini-slot is 1, and in this case, a first bit is used to indicate an SR associated with the SR configuration #3.
[0165] The previous example is merely used to explain this request, and should not be interpreted as any limitation. In method 4, the plurality of time units can be consecutive, or it can be non-consecutive.
[0166] Method 4 is described merely using an example where an attribute of an uplink control channel is a length of a time unit occupied by an uplink control channel. For another uplink control channel attribute, similar processing applies.
[0167] If the amount of time units occupied by an uplink control channel is the same as the amount of Petition 870260067112, dated 07 / 07 / 2026, page 47 / 83 39 / 61 time units occupied by another uplink control channel, for example, both are two time units, it is considered that the attributes of the uplink control channels are the same. Otherwise, the attributes are different.
[0168] If the format of an uplink control channel is the same as that of another uplink control channel, for example, both are uplink control channels in a first format, the attributes of the uplink control channels are considered to be the same. Otherwise, the attributes are different.
[0169] If the minimum number of bits that can be carried by an uplink control channel is the same as the minimum number of bits that can be carried by another uplink control channel, for example, both are two bits, the attributes of the uplink control channels are considered to be the same. Otherwise, the attributes are different.
[0170] If the maximum number of bits that can be carried by an uplink control channel is the same as the maximum number of bits that can be carried by another uplink control channel, for example, both are two bits, the attributes of the uplink control channels are considered to be the same. Otherwise, the attributes are different.
[0171] One applicable method of operation when the attributes are the same or different is similar to a method for the length of a time unit occupied by an uplink control channel. In other words, a quantity of SR configurations is a quantity of SR configurations associated with the same attribute. Therefore, the details are not described again in this report.
[0172] In method 4, the SR settings associated with different uplink control channel attributes can be reported distinctly, with greater flexibility.
[0173] In this application, a location relationship between an SR bit and a HARQ bit in a bit sequence may include, but is not limited to, the following:
[0174] (1) First location relation: As shown in FIG. Petition 870260067112, dated 07 / 07 / 2026, page 48 / 83 40 / 61 13A, an SR bit is adjacent to a HARQ bit, and the SR bit is added after the HARQ bit.
[0175] (2) Second location relation: As shown in FIG. 13B, an SR bit is adjacent to a HARQ bit, and the HARQ bit is added after the SR bit. Because the capacity of an uplink control channel is limited, when the total amount of information to be transmitted is greater than the maximum capacity, the information in the tail needs to be discarded so that the information arranged first can be protected. Therefore, when the SR bit is more important, the SR bit is arranged first, to protect the SR bit.
[0176] (3) Third location relation: As shown in FIG. 13C, there is another bit between an SR bit and a HARQ bit, and the SR bit is added after the HARQ bit. When the importance of some information is greater than the importance of the SR bit but less than or equal to the importance of the HARQ bit, the information can be organized in this place. A beneficial effect of the organization is equivalent to (2), where important information is organized first.
[0177] (4) Fourth location relation: As shown in FIG. 13D, there is another bit between an SR bit and a HARQ bit, and the HARQ bit is added after the SR bit. When the importance of some information is greater than the importance of the HARQ bit but less than or equal to the importance of the SR bit, the information can be organized in this place. A beneficial effect of the organization is equivalent to (2), where important information is organized first.
[0178] (5) Fifth location relation: As shown in FIG. 13E, an SR bit is added after a first set of HARQ bits, and a second set of HARQ bits are added after the SR bit. One advantage of this method is as follows: When a frequency domain resource occupied by an uplink control channel in which HARQ bits and SR bits are carried is allowed to change, for example, when the uplink control channel in a first symbol is in a first frequency domain resource and the uplink control channel in a second symbol is in a second frequency domain resource, some HARQ bits and some SR bits are placed in one of the Petition 870260067112, dated 07 / 07 / 2026, page 49 / 83 41 / 61 frequency domain resources, and the remaining HARQ bits and the remaining SR bits are placed in the other frequency domain resource, thereby improving the accuracy in receiving partial information.
[0179] FIG. 13A to FIG. 13E shows only one concatenation relationship between an SR bit and a HARQ bit in an original bit sequence before encoding. In this report, this application does not represent any particular limitation on other bits in (3) and (4), which may be any other bits before encoding.
[0180] In this application, a time unit can be a symbol, a slot, a mini-slot, or a subframe. For definitions of these time units, refer to the LTE standards. However, the definitions of these time units are not limited to the LTE standards. The definitions of these time units in a future communications standard may be different.
[0181] Based on the main principles of the prior invention, a general procedure for a signal transmission method provided in this application is described below. As shown in FIG. 7, the signal transmission method provided in this application may include the following steps.
[0182] S101. A terminal device generates a first bit. In this report, the first bit is the previous SR bit and can be used to indicate a scheduling request associated with a first scheduling request configuration. The first scheduling request configuration can be at least one of a plurality of scheduling request configurations configured by a network device for the terminal device.
[0183] Specifically, the generation, by a terminal device, of a first bit may include at least one of the following actions: (1) determining a quantity of the first bit, and performing channel encoding on the first bit; and (2) determining a bit state of the first bit, and determining the first bit based on an attribute of a resource that needs to be requested.
[0184] At least one escalation request configuration in the plurality of escalation request configurations can be dynamically configured by the network device, or configured by the network device using layer signaling. Petition 870260067112, dated 07 / 07 / 2026, page 50 / 83 42 / 61 superior. In this report, upper-layer signaling can be a Media Access Control (MAC) signaling layer or a Radio Resource Control (RRC) signaling layer. At least one escalation request configuration can be at least one of a plurality of escalation request configurations dynamically configured by the network device for the endpoint device, or at least one escalation request configuration can be at least one of a plurality of escalation request configurations configured by the network device for the endpoint using upper-layer signaling.
[0185] For a description of at least one escalation request configuration and the plurality of escalation request configurations, refer to the previous section on the principles of the invention. The details are not described again in this report.
[0186] S102. The terminal device generates a hybrid auto-repeat request bit. The hybrid auto-repeat request bit is used to return a decoding result of one or more downlink data blocks by the terminal device, and the result can be a positive ACK acknowledgment or a negative ACK acknowledgment. ACK indicates that the terminal has correctly performed the decoding. NACK indicates that an error has occurred during decoding by the terminal. It can be understood that if the terminal returns a negative acknowledgment, the network device retransmits data indicating that an error occurred during decoding by the terminal.
[0187] Specifically, the generation, by the terminal device, of a HARQ bit may include at least one of the following actions: determining a HARQ bit quantity, and performing channel encoding on the HARQ bit; and determining a bit state of the HARQ bit, and determining the HARQ bit based on a downlink data reception state.
[0188] S103. The terminal device sends the hybrid auto-repeat request bit and the first bit in a time unit. Correspondingly, the network device can receive the hybrid auto-repeat request bit and the first bit from the terminal device in the time unit. Petition 870260067112, dated 07 / 07 / 2026, pp. 51 / 83 43 / 61
[0189] S104. The network device can determine, based on the first bit, the scheduling request associated with the first scheduling request configuration.
[0190] In one implementation, with reference to a bit SR design solution provided in subsequent embodiment 1, the network device can determine, based on a state of each bit in the first bit, an SR (a positive SR or a negative SR) associated with a corresponding SR configuration for each bit.
[0191] For example, consider that a possible state of each bit in the first bit and a possible SR configuration corresponding to each bit are shown in Table 5. If the first bits actually transmitted are “0XXX”, the network device can determine that the scheduling request associated with the first scheduling request configuration is a negative SR associated with an SR #0 configuration. If the first bits actually transmitted are “X1XX”, the network device can determine that the scheduling request associated with the first scheduling request configuration is a positive SR associated with an SR #1 configuration. The example is merely used to explain this request, and should not be interpreted as any limitation.
[0192] In another implementation, with reference to a bit SR design solution provided in subsequent embodiment 1, the network device can determine, based on a first bit state, an SR (a positive SR or a negative SR) corresponding to the state.
[0193] For example, it is considered that a possible state of each bit in the first bit and a possible SR configuration corresponding to each bit are shown in Table 6-1. If the first bits actually transmitted are “001”, the network device can determine that the scheduling request associated with the first scheduling request configuration is a positive SR associated with an SR configuration #0. If the first bits actually transmitted are “000”, the network device can determine that the scheduling request associated with the first scheduling request configuration is: the negative SRs associated with SR configurations #0, #1, #2 and #3, in other words, the SRs associated with all SR configurations are the negative SRs. Petition 870260067112, dated 07 / 07 / 2026, page 52 / 83 44 / 61
[0194] Not limited to the case shown in FIG. 7, there may be another timing sequence of S101 and S102. For example, S102 is performed before S101. This is not limited to this application.
[0195] The following describes, in detail with reference to a plurality of modes, how to design the SR bit.
[0196] (1) Modality 1
[0197] In this embodiment, a bit in the SR bit (i.e., the first bit) is used to indicate a scheduling request associated with an SR setting in at least one SR setting (i.e., the first SR setting). It can be understood that a first SR setting corresponds to a bit in the SR bit. Specifically, an SR setting corresponds to a bit in the SR bit. In this case, an OSR quantity of SR bits is equal to a quantity of the plurality of SR settings (i.e., the plurality of SR settings mentioned in the principles of the prior invention) configured for the terminal. This is one way in which the OSR quantity of SR bits is related to the quantity of the plurality of SR settings. For a definition of the quantity of the plurality of SR settings mentioned in the principles of the prior invention, refer to the previous section on the principles of the invention. The details are not described again in this report.
[0198] A bit in the SR bit is used to indicate whether an SR associated with an SR setting in the first SR setting is a positive SR or a negative SR. Specifically, a bit in the SR bit is used to indicate whether an SR associated with an SR setting corresponding to the bit is a positive SR or a negative SR. For example, a bit in the SR bit is considered to correspond to an SR setting #0. Table 4 shows the bit and a bit indication meaning. Table 4 Bit State: Meaning of a bit indication (a corresponding SR configuration, and an SR associated with the SR configuration) 0: Negative SR associated with an SR configuration #0 1: Positive SR associated with an SR configuration #0
[0199] The left column in Table 4 represents a state (“0” or “1”) of the bit, and the right column in Table 4 represents a SR indicated by the bit. When the bit state is “0”, this indicates that the SR indicated by the bit is an SR. Petition 870260067112, dated 07 / 07 / 2026, p. 53 / 83 45 / 61 negative associated with SR #0 configuration; or when the bit status is “1”, this indicates that the SR indicated by the bit is a positive SR associated with SR #0 configuration. Table 4 is merely intended to explain this application. In practical application, a correspondence between the bit state and the SR indicated by the bit may be contrary to that shown in Table 4, and this is not limited to this report.
[0200] The following describes Mode 1 in detail using an example where there are four SR bits (OSR= 4).
[0201] The four SR bits are considered to correspond to four different SR configurations: an SR #3 configuration, an SR #2 configuration, an SR #1 configuration, and an SR #0 configuration.
[0202] Optionally, as shown in FIG. 14A, the four SR bits can correspond, respectively, in order from most significant bit to least significant bit, to an SR #3 configuration, an SR #2 configuration, an SR #1 configuration, and an SR #0 configuration. Optionally, as shown in FIG. 14B, the four SR bits can correspond, respectively, in order from least significant bit to most significant bit, to an SR #3 configuration, an SR #2 configuration, an SR #1 configuration, and an SR #0 configuration.
[0203] Not limited to the ways shown in FIG. 14A and FIG. 14B, the four SR bits can correspond to four different SR configurations in another way, and this is not limited to this report.
[0204] Specifically, a match similar to the match shown in FIG. 14A or FIG. 14B, which lies between an SR setting and a bit in the SR bits, can be dynamically configured by a network device, or can be configured by a network device using higher-layer signaling. The match can include B SR settings, and B bits, respectively, corresponding to the B SR settings. In this way, a terminal device can determine, based on the match, each bit corresponding to each SR setting of at least one SR setting (i.e., the first SR setting) in the SR bits. Here, B is a positive integer. In this application, the match configured by the network device or configured using higher-layer signaling can be referred to as a first Petition 870260067112, dated 07 / 07 / 2026, p. 54 / 83 46 / 61 correspondence.
[0205] The correspondence shown in FIG. 14A is considered to be used for the four SR bits and the four SR configurations. Table 5 shows an example of a meaning indication for each bit in the SR bits. Table 5 Status Meaning of bit indication 0XXX Negative SR associated with an SR #0 configuration 1XXX Positive SR associated with an SR #0 configuration X0XX Positive SR associated with an SR #1 configuration X1XX Negative SR associated with an SR #1 configuration XX0X Positive SR associated with an SR #2 configuration XX1X Negative SR associated with an SR #2 configuration XXX0 Positive SR associated with an SR #3 configuration XXX1 Negative SR associated with an SR #3 configuration
[0206] In Table 5, row 1 and row 2 represent the first most significant bit of the SR bits and a bit meaning. When a bit state is “0”, this indicates that an SR indicated by the bit is a negative SR associated with an SR #0 configuration; in other words, an SR associated with an SR #0 configuration reported by a terminal is a negative scheduling request; or when a bit state is “1”, this indicates that an SR indicated by the bit is a positive SR associated with an SR #0 configuration; in other words, an SR associated with an SR #0 configuration reported by a terminal is a positive scheduling request. In this case, “X” in row 1 and row 2 means that if a state of any other bit is 0 or 1, it does not affect a match between the first bit and the SR #0 configuration, and does not affect the indication, by the first bit, of whether the SR associated with the SR #0 configuration is a positive SR or a negative SR.Similarly, every two lines of the remaining lines in Table 5 represent a bit in the SR bits and a bit indication meaning, and the details are not described again in this report.
[0207] In the example shown in Table 5, if a bit state of the SR bits is “0011”, this indicates that the indicated SRs are: a negative SR associated with an SR #0 configuration, a negative SR associated with an SR #1 configuration, a positive SR associated with an SR #2 configuration, and a positive SR Petition 870260067112, dated 07 / 07 / 2026, p. 55 / 83 47 / 61 is associated with an SR #3 configuration. In other words, the terminal device actually reports two positive SRs: one positive SR associated with an SR #2 configuration and one positive SR associated with an SR #3 configuration. Similarly, when the values of a plurality of other bits in the SR bits are “1”, this indicates that the terminal device actually reports the positive SRs associated with a plurality of other SR configurations. In particular, when the bit state of the SR bits is “1111”, this indicates that the SR bits allow the terminal device to simultaneously report the positive SRs associated with a maximum of four different SR configurations.
[0208] This application is not limited to that SR configuration which corresponds to one bit in the SR bits. In Embodiment 1, an SR configuration may alternatively correspond to a plurality of bits in the SR bits. In other words, a plurality of bits may be used to indicate an SR associated with an SR configuration. In this case, an OSR quantity of SR bits is equal to an integer multiple of an SR configuration quantity (i.e., the plurality of SR configurations mentioned in the principles of the prior invention) configured by the network device for the terminal. This is another way in which the OSR quantity of SR bits is related to the quantity of SR configurations configured by the network device for the terminal. For a definition of the quantity of the plurality of SR configurations mentioned in the principles of the prior invention, refer to the previous section on the principles of the invention. The details are not described again in this report.
[0209] For example, in the example shown in Table 5, the two most significant bits of the SR bits are used to indicate an SR associated with an SR #0 configuration. When one state of the two bits is “00”, this indicates that the SR indicated by the two bits is a negative SR associated with the SR #0 configuration; or when one state of the two bits is a non-zero state (“01”, or “10”, or “11”), this indicates that the SR indicated by the two bits is a positive SR associated with the SR #0 configuration. The example is merely an implementation provided in this application and should not be interpreted as any limitation, and the implementation may vary in practical application. In this way, a plurality of non-zero states can be used to indicate a plurality of available attributes (e.g., a TTI) of an uplink control channel carrying an SR, so as to instruct the network device to Petition 870260067112, dated 07 / 07 / 2026, p. 56 / 83 48 / 61 select an attribute from the plurality of attributes, thus adopting a scenario of a plurality of uplink control channel attributes in SR management.
[0210] It can be learned from the previous description that, in the SR bit design solution provided in Mode 1, a plurality of SRs can be reported, and the SRs associated with a plurality of different SR configurations can be reported flexibly.
[0211] (2) Modality 2
[0212] In this mode, a bit state of an SR bit (i.e., a first bit) is used to indicate a scheduling request associated with at least one SR configuration (i.e., the first SR configuration). The SR (positive SR or negative SR) associated with the first SR configuration corresponds to the state of the SR bit.
[0213] Optionally, a first SR bit state is used to indicate that the SR associated with the first SR setting is a negative SR.
[0214] Optionally, at least one SR bit state other than the first state is used to indicate that the SR associated with the first SR setting is a positive SR.
[0215] Optionally, no SR bit state other than the first state is used to indicate that any of the SRs associated with the first SR setting is a negative SR.
[0216] Specifically, in a plurality of SR bit states, only one state (e.g., a zero state) corresponds to a negative SR associated with the first SR configuration. In other words, only one state is used to indicate that the SRs associated with the first SR configuration are all negative SRs. It can be understood that at least one state other than the only state is used to indicate that any of the SRs associated with the first SR configuration are a negative SR. At least one state other than the only state corresponds to a positive SR associated with at least one SR configuration in the first SR configuration. In other words, at least one state other than the only state is used to indicate a positive SR associated with at least one SR configuration. In this application, only the state can be referred to as a first state.
[0217] It is considered that the SR bits have three bits, and the states of Petition 870260067112, dated 07 / 07 / 2026, p. 57 / 83 49 / 61 three bits are used to indicate the SRs associated with four different SR configurations. Table 6-1 and Table 6-2 show examples of a meaning indication for each state of the SR bits. Table 6-1 Bit Status Meaning of bit indication 000 Negative SRs associated with SR configurations #0, #1, #2 and #3 001 Positive SR associated with an SR configuration #0 010 Positive SR associated with an SR configuration #1 011 Positive SR associated with an SR configuration #2 100 Positive SR associated with an SR configuration #3 101 Reserved 110 Reserved 111 Reserved Table 6-2 Bit State Meaning of Bit Indication 000 Negative SRs associated with SR configurations #0, #1, #2, and #3 001 Positive SR associated with an SR configuration #0 010 Positive SR associated with an SR configuration #1 011 Positive SR associated with an SR configuration #2 100 Positive SR associated with an SR configuration #3 101 Positive SRs associated with an SR configuration #0 and an SR configuration #1 110 Positive SRs associated with an SR configuration #2 and an SR configuration #3 111 Positive SRs associated with SR configurations #0, #1, #2, and #3
[0218] When the SR bit status is “000”, this indicates that the SRs associated with SR configurations #0, #1, #2, and #3 are all negative SRs. In other SR bit states, at least one state represents a positive SR associated with at least one SR configuration. For details, refer to Table 6-1 and Table 6-2.
[0219] It can be learned from the previous description that, in the SR bit design solution provided in Mode 2, a quantity of Petition 870260067112, dated 07 / 07 / 2026, pp. 58 / 83 The amount of information carried by an uplink control channel can be reduced by indicating, using a relatively small number of bits, each SR associated with at least one SR configuration (i.e., the first SR configuration), thereby improving the successful transmission rate of the uplink control channel.
[0220] Specifically, a match similar to a match shown in Table 6-1 or Table 6-2, which is between an SR and an SR bit state, can be dynamically configured by a network device, or can be configured by a network device using higher-layer signaling. The match can include the SRs associated with the P SR settings, and Q states corresponding to the SRs associated with the P SR settings. In this way, a terminal can determine, based on the match, a state corresponding to an SR associated with at least one SR setting (i.e., the first SR setting). In this report, Q > 3, Q is a positive integer, P > 2, and P is a positive integer. In this application, the match can be referred to as a second match.
[0221] In Embodiment 2, an OSR quantity of SR bits can be: OSR = ceil(log2 (1+Nconfiguration)), where Nconfiguration represents an amount of SR configurations (i.e., the plurality of SR configurations mentioned in the principles of the prior invention) configured for the terminal, and ceil represents rounding up to the nearest integer. This is another way in which the OSR quantity of SR bits is related to the quantity of SR configurations configured by the network device for the terminal. For a definition of the quantity of the plurality of SR configurations mentioned in the principles of the prior invention, refer to the previous section on the principles of the invention. The details are not described again in this report.
[0222] In Mode 2, a state of the SR bits can alternatively be used to indicate the SRs associated with a plurality of SR configurations.
[0223] For example, a state “101” in table 6 to 2 is used to indicate a positive SR associated with an SR #0 configuration and a positive SR associated with an SR #1 configuration. In other words, when the SR bits are “101”, the terminal device reports a positive SR associated with a Petition 870260067112, dated 07 / 07 / 2026, p. 59 / 83 51 / 61 configuration SR #0 and a positive SR associated with a configuration SR #1. In this case, it can be understood that this is equivalent to reports of a negative SR associated with a configuration SR #2 and a negative SR associated with a configuration SR #3. Similarly, a state “110” in table 6 to 2 can be used to indicate a positive SR associated with a configuration SR #3 and a positive SR associated with a configuration SR #2; and a state “111” in table 6 to 2 can be used to indicate a positive SR associated with a configuration SR #3, a positive SR associated with a configuration SR #2, a positive SR associated with a configuration SR #1, and a positive SR associated with a configuration SR #0. The example is merely used to explain this request and should not be interpreted as any limitation.
[0224] Optionally, an index of an SR configuration associated with a positive SR can be used as a maximum value, and the SRs associated with the SR configurations whose indices are less than the maximum value are all positive SRs. In this way, the terminal device can indicate, based on only one state of an SR bit corresponding to this positive SR, the positive SRs associated with a plurality of SR configurations.
[0225] For example, consider that a state of the SR bits is “100”, used to indicate a positive SR associated with an SR #3 configuration. In this case, the index “3” of the SR #3 configuration is used as a maximum value, and the SRs respectively associated with an SR #2 configuration, an SR #1 configuration, and an SR #0 configuration whose indices are less than “3” are all positive SRs. The example is merely used to explain this request, and should not be interpreted as any limitation.
[0226] Optionally, an index of an SR configuration associated with a positive SR can be used as a minimum value, and the SRs associated with the SR configurations whose indices are greater than the minimum value are all positive SRs. In this way, the terminal device can indicate, based on only one state of an SR bit corresponding to the positive SR, the positive SRs associated with a plurality of SR configurations.
[0227] For example, consider that a state of the SR bits is “001”, used to indicate a positive SR associated with an SR #1 configuration. In this case, the index “1” of the SR #1 configuration is used as a minimum value, and the SRs respectively associated with an SR #2 configuration and a configuration Petition 870260067112, dated 07 / 07 / 2026, pp. 60 / 83 52 / 61 SR #3, whose indices are greater than "1", are all positive SRs. The example is merely used to explain this request and should not be interpreted as any limitation.
[0228] With reference to Mode 1 or Mode 2, in some optional implementations, the number of HARQ bits sent along with the SR bit is greater than or equal to X, X > 2, and X is a positive integer. This avoids affecting a successful transmission rate for a small number of HARQ bits. This is because the reliability of the HARQ transmission design increases as the number of HARQ bits increases. In other words, when the number of HARQ bits is relatively small, it is not appropriate to add a plurality of SR bits after a HARQ bit.
[0229] With reference to Mode 1 or Mode 2, in some optional implementations, the length of a current time unit is greater than or equal to Y symbols, Y > 1, and Y is a positive integer. This avoids affecting the successful transmission rate of an uplink control channel in a time unit of a short length. This is because the transmission power of an uplink control channel in a current time unit increases as the time length of a current time domain resource increases, resulting in greater reliability. In other words, when the time length of the current time unit is relatively small, it is not suitable for the uplink control channel in the current time unit to carry a plurality of SR bits.
[0230] FIG. 15 shows a wireless communications system, a terminal, and a network device, according to this application. The wireless communications system 10 includes: a terminal 400 and a network device 500. Terminal 400 can be terminal 200 in the embodiment in FIG. 4, network device 500 can be network device 300 in the embodiment in FIG. 5, and wireless communications system 10 can be wireless communications system 100 described in FIG. 3, as described separately below.
[0231] As shown in FIG. 15, terminal 400 may include: a generation unit 401 and a transmission unit 403.
[0232] The 401 generation unit can be configured to generate a first bit. The first bit can be used to indicate a request for Petition 870260067112, dated 07 / 07 / 2026, pp. 61 / 83 53 / 61 scheduling is associated with a first scheduling request configuration, and the first scheduling request configuration can be at least one of a plurality of scheduling request configurations.
[0233] The 401 generation unit can be further configured to generate a hybrid auto-repeat request bit.
[0234] The 403 sending unit can be configured to send the hybrid auto-repeat request bit and the first bit in a time unit.
[0235] In this application, a quantity of the plurality of scheduling request configurations can be equal to a quantity of scheduling request configurations in the unit of time, or a quantity of the plurality of scheduling request configurations can be equal to a quantity of all scheduling request configurations.
[0236] Specifically, the first bit can indicate, in the following ways, the scheduling request associated with the first scheduling request configuration:
[0237] In one way, a bit in the first bit can be used to indicate a scheduling request associated with a scheduling request configuration in the first scheduling request configuration.
[0238] For details on the first method, refer to Option 1. The details are not described again in this report.
[0239] In a second way, a first bit state can be used to indicate that the scheduling request associated with the first scheduling request setting is a negative scheduling request, at least one first bit state other than the first state can be used to indicate that the scheduling request associated with the first scheduling request setting is a positive scheduling request, and no first bit state other than the first state is used to indicate that any of the scheduling requests associated with the first scheduling request setting is a negative scheduling request. Petition 870260067112, dated 07 / 07 / 2026, pages 62 / 83 54 / 61
[0240] For details on the second method, refer to Option 2. The details are not described again in this report.
[0241] Specifically, a quantity of the first bit can be related to the quantity of the plurality of scheduling request configurations, specifically in the following ways:
[0242] In a correlational manner, when the design solution in Mode 1 is used for the SR bits, an OSR quantity of SR bits can be equal to the quantity of the plurality of scheduling request configurations.
[0243] In another way of correlation, when the design solution in Mode 2 is used for the SR bits, an OSR quantity of SR bits can be: OSR= ceil(log2 (1 +Nconfiguration)), where Nconfiguration represents a quantity of SR configurations (i.e., the plurality of SR configurations mentioned in the principles of the prior invention) configured for the terminal, and ceil represents rounding up to the next integer.
[0244] The technical advantages of correlating the quantity of the first bit with the quantity of the scheduling request plurality are as follows: In such a default manner, the network device and the terminal device can determine the quantity of the first bit before the first bit is sent, so that the network device and the terminal device do not have different understandings of the quantity of the first bit, thus avoiding a case where the first bit fails to be received due to different understandings.
[0245] In some optional implementations, the number of HARQ bits sent along with the SR bit is greater than or equal to X, X > 2, and X is a positive integer. This avoids affecting a successful transmission rate for a small number of HARQ bits. This is because the reliability of the HARQ transmission design increases as the number of HARQ bits increases. In other words, when the number of HARQ bits is relatively small, it is not appropriate to add a plurality of SR bits after a HARQ bit.
[0246] In some optional implementations, a time unit length is greater than or equal to Y symbols, Y > 1, and Y is a positive integer. This avoids affecting a successful transmission rate of a channel. Petition 870260067112, dated 07 / 07 / 2026, pp. 63 / 83 55 / 61 uplink control in a time unit of a short length. This happens because the transmission power of an uplink control channel in a current time unit increases as the time length of a current time domain resource increases, bringing greater reliability. In other words, when the time length of the current time unit is relatively small, it is not suitable for the uplink control channel in the current time unit to carry a plurality of SR bits.
[0247] It may be understood that, for the specific implementation of each functional unit included in terminal 400, reference should be made to the previous modalities. The details are not described again in this report.
[0248] As shown in FIG. 15, the network device 500 may include: a receiving unit 501 and a determination unit 503.
[0249] The receiving unit 501 can be configured to receive, in one unit of time, a hybrid auto-repeat request bit and a first bit that are sent by a terminal device. The first bit can be used to indicate a scheduling request associated with a first scheduling request configuration, and the first scheduling request configuration can be at least one of a plurality of scheduling request configurations.
[0250] The 503 determination unit can be configured to determine, based on the first bit, the scheduling request associated with the first scheduling request setting.
[0251] In this application, a quantity of the plurality of scheduling request configurations can be equal to a quantity of scheduling request configurations in the unit of time, or a quantity of the plurality of scheduling request configurations can be equal to a quantity of all scheduling request configurations.
[0252] Specifically, the first bit can indicate, in the following ways, the scheduling requests associated with the first scheduling request configuration:
[0253] In one way, a bit in the first bit can be used to indicate a scheduling request associated with a Petition 870260067112, dated 07 / 07 / 2026, pages 64 / 83 56 / 61 scheduling request configuration in the first scheduling request configuration. In this way, the 503 determination unit can be configured to determine, based on a state of each bit in the first bit, an SR (a positive SR or a negative SR) associated with a corresponding SR configuration for each bit.
[0254] For details on the first method, refer to Option 1. The details are not described again in this report.
[0255] In a second way, a first bit state can be used to indicate that the scheduling request associated with the first scheduling request setting is a negative scheduling request, at least one first bit state other than the first state can be used to indicate that the scheduling request associated with the first scheduling request setting is a positive scheduling request, and no first bit state other than the first state is used to indicate that any of the scheduling requests associated with the first scheduling request setting is a negative scheduling request. In this way, determination unit 503 can be configured to determine, based on a first bit state, an SR (a positive SR or a negative SR) corresponding to the state.
[0256] For details on the second method, refer to Option 2. The details are not described again in this report.
[0257] Specifically, a quantity of the first bit can be related to the quantity of the plurality of scheduling request configurations, specifically in the following ways:
[0258] In a correlational manner, when the design solution in Mode 1 is used for the SR bits, an OSR quantity of SR bits can be equal to the quantity of the plurality of SR configurations.
[0259] In another way of correlation, when the design solution in Mode 2 is used for the SR bits, an OSR quantity of SR bits can be: OSR= ceil(log2 (1 +Nconfiguration)), where Nconfiguration represents a quantity of SR configurations (i.e., the plurality of SR configurations mentioned in the principles of the prior invention) configured for the terminal, and ceil represents rounding up to the next integer. Petition 870260067112, dated 07 / 07 / 2026, pp. 65 / 83 57 / 61
[0260] In some optional implementations, the number of HARQ bits sent along with the SR bit is greater than or equal to X, X > 2, and X is a positive integer. This avoids affecting a successful transmission rate for a small number of HARQ bits. This is because the reliability of the HARQ transmission design increases as the number of HARQ bits increases. In other words, when the number of HARQ bits is relatively small, it is not appropriate to add a plurality of SR bits after a HARQ bit.
[0261] In some optional implementations, a time unit length is greater than or equal to Y symbols, Y > 1, and Y is a positive integer. This avoids affecting the successful transmission rate of an uplink control channel in a time unit of a short length. This is because the transmission power of an uplink control channel in a current time unit increases as the time length of a current time domain resource increases, bringing greater reliability. In other words, when the time length of the current time unit is relatively small, it is not suitable for the uplink control channel in the current time unit to carry a plurality of SR bits.
