[0052] FIG1 shows a schematic diagram of a network architecture 100 provided by an exemplary embodiment of the present application. The network architecture 100 includes: a terminal device 10 , a network device 20 , and a core network device 30 .

[0053] The terminal device 10 may refer to a user equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, a remote terminal, a mobile device, a wireless communication device, a user agent, or a user device. Optionally, the terminal device 10 may also be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a terminal device in the fifth generation mobile communication system (5GS) or a terminal device in the future evolved public land mobile communication network (PLMN), etc., and the embodiments of the present application are not limited to this. For the convenience of description, the devices mentioned above are collectively referred to as terminal devices. The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 can be distributed in the cell managed by each network device 20.

[0054] The network device 20 is a device deployed in the access network to provide wireless communication functions for the terminal device 10. The network device 20 may include various forms of macro base stations, micro base stations, relay stations, access points, etc. In systems using different wireless access technologies, the names of devices with network device functions may be different. For example, in the 5th Generation New Radio (5G NR) system, it is called the next generation base station (gNodeB, gNB). With the evolution of communication technology, the name "network device" may change. For the convenience of description, in the embodiment of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as network devices. Optionally, a communication relationship can be established between the terminal device 10 and the core network device 30 through the network device 20. For example, in a Long Term Evolution (LTE) system, the network device 20 may be an Evolved Universal Terrestrial Radio Access Network (EUTRAN) or one or more evolved base stations in the EUTRAN. In a 5G NR system, the network device 20 may be a Radio Access Network (RAN) or one or more gNBs in the RAN. In the embodiments of the present application, unless otherwise specified, a network device refers to a network device 20, such as a base station.

[0055] The core network device 30 is deployed in the core network. The functions of the core network device 30 are mainly to provide user connections, user management, and service bearer, and to provide an interface to the external network as a bearer network. For example, the core network equipment in the 5G NR system includes the Access and Mobility Management Function (AMF) network element, the User Plane Function (UPF) network element, and the Session Management Function (SMF) network element.

[0056] In some embodiments, the network device 20 and the core network device 30 communicate with each other via an air interface technology, such as the NG interface in the 5G NR system. The network device 20 and the terminal device 10 communicate with each other via an air interface technology, such as the Uu interface.

[0057] The following describes the related technologies involved in the embodiments of this application:

[0058] (1) Configured Grant Physical Uplink Shared CHannel (CG PUSCH)

[0059] NR uplink supports semi-static periodic transmission mode, namely configured grant PUSCH transmission, which includes two types:

[0060] Type 1CG: After the Radio Resource Control (RRC) configures the transmission parameters, they take effect without the need for Downlink Control Information (DCI) activation.

[0061] Type 2CG: After RRC configures the transmission parameters, they need to be activated by DCI to take effect.

[0062] CG supports symbol-level periods of 2 symbols or 7 symbols, and periods at the time slot level of {1, 2, 4, 5, 8, 10, 16, 20, 32, 40…}. In Release 15 / 16 / 17 (R15 / 16 / 17), PUSCH is transmitted once in one CG period (i.e., there is only one PUSCH opportunity). In R16, a UE can be configured with multiple CG configurations at the same time. The parameters of different CG configurations are configured independently. The UE determines the corresponding CG PUSCH transmission resources for each CG configuration.

[0063] (2) CG Uplink Control Information (CG-UCI)

[0064] NR introduces CG uplink control signaling (CG-Uplink Control Information, CG-UCI) to support the transmission of CG PUSCH on unlicensed bands. That is, the UE embeds CG-UCI information in the transmitted CG PUSCH to notify the base station of the parameters shown in Table 1:

[0065] Table 1

[0066] The first three items of information are the HARQ process number, redundancy version, and new data indicator (NDI) corresponding to the current CG PUSCH. The last item indicates whether the subsequent COT resources where the current CG PUSCH is located can be shared for downlink transmission.

[0067] (3) Extended Reality (XR)

[0068] At the relevant meeting, a research project titled "eXtended Reality and cloud game evaluations for NR" was approved. The services studied in this project include augmented reality (AR) / virtual reality (VR) / cloud game (CG), etc. A major service of XR / CG is video streaming. Its transmission rate is measured in frames per second (fps), which can be 30fps, 60fps, 90fps, and 120fps. The corresponding video stream period is {33.33ms, 16.67ms, 11.11ms, 8.33ms}.

[0069] XR data features variable packet sizes with a large average. For example, for AR / VR systems with a 100-megabit-per-second (Mbps) transmission rate, the average uplink packet size is 20,833 bytes, the maximum is 31,250 bytes, and the minimum is 10,417 bytes. This means that the size of the packet to be transmitted in each cycle ranges from [10,417 to 31,250] bytes. In a real-world system with 100 Mbps bandwidth, transmitting a 20,833-byte packet requires approximately four time slots of transmission resources.

[0070] Currently, the 3rd Generation Partnership Project (3GPP) has determined that it supports configuring multiple PUSCH opportunities within a CG cycle for transmitting XR large data packets. In addition, multiple sets of CGs can be configured to transmit XR large data packets. When the amount of data transmitted in a certain period is relatively small and does not need to occupy multiple pre-configured PUSCH opportunities, the UE can notify the base station of the unused PUSCH opportunities. The base station can reallocate the unused PUSCH opportunities to other UEs for data transmission, thereby improving system efficiency.

[0071] FIG2 shows a flow chart of a method for indicating channel resources provided by an exemplary embodiment of the present application. The method is executed by a terminal device and includes:

[0072] Step 210: Send a first channel, the first channel carries first information, and the first information is used to indicate that the preconfigured channel resources are not used; wherein the physical resources occupied by the first channel are physical resources in a first resource set, and the first resource set includes at least one resource unit.

[0073] Since the pre-configured channel resources are one or more, such as multiple ones that appear periodically, in different embodiments, "the first information is used to indicate that the pre-configured channel resources are not used" can be understood as at least one of the following meanings:

[0074] The first information is used to indicate that all pre-configured channel resources are not used, or that all pre-configured channel resources are not used;

[0075] The first information is used to indicate that a portion of pre-configured channel resources is not used, or a portion of pre-configured channel resources is not used;

[0076] The first information is used to indicate that all remaining pre-configured channel resources are not used;

[0077] The first information is used to indicate that the remaining pre-configured channel resources in the current period are not used;

[0078] The first information is used to explicitly indicate unused preconfigured channel resources. For example, the first information explicitly carries information such as a resource index and a resource location of the unused preconfigured channel resources.

[0079] The first information is used to implicitly indicate unused preconfigured channel resources. For example, the first information does not carry information such as the resource index and resource location of the unused preconfigured channel resources. However, based on the time domain position corresponding to the first information, it implicitly indicates that the remaining preconfigured channel resources in the current period are not used. For another example, the first information is used to implicitly indicate that all remaining preconfigured channel resources after the time domain position corresponding to the first information are not used. For another example, the first information is used to implicitly indicate that the next preconfigured channel resource after the time domain position corresponding to the first information is not used. For another example, the first information is used to implicitly indicate that the preconfigured channel resources within a preset duration after the time domain position corresponding to the first information are not used.

[0080] The first information is used to indicate that there are unused preconfigured channel resources, but the first information does not clearly indicate which preconfigured channel resources are unused. The unused preconfigured channel resources are determined according to the protocol agreement, preconfiguration, or other autonomous implementation methods.

[0081] For the first resource collection:

[0082] The first resource set includes at least one time-domain physical resource, such as a time slot, a sub-time slot, a symbol, or a pre-configured physical channel time-domain resource, where the pre-configured physical channel time-domain resource includes a time-domain resource of a physical uplink control channel (PUCCH) or a PUSCH or a PUSCH transmission opportunity configured through RRC signaling; and / or,

[0083] The first resource set includes at least one frequency domain physical resource, such as a frequency band, a subband, a resource block (RB), a subcarrier, and a pre-configured physical channel frequency domain resource. The pre-configured physical channel frequency domain resource includes the frequency domain resources of PUCCH or PUSCH configured through RRC signaling.

[0084] In some embodiments, the first resource set is periodic; or the physical resources in the first resource set are periodic.

[0085] In some embodiments, the first resource set is determined according to a transmission opportunity of a periodic channel, and the transmission opportunity may also be referred to as a transmission resource.

[0086] Among them, at least one resource unit included in the first resource set is determined based on Q transmission opportunities of the periodic channel, where Q is a positive integer; or, at least one resource unit is determined based on the resource unit where at least one transmission opportunity of the periodic channel is located.

[0087] In some embodiments, the Q transmission opportunities are configured by the network device; or, at least one transmission opportunity is configured by the network device.

[0088] In some embodiments, the at least one resource unit is the Q transmission opportunities of the periodic channel; or, the at least one resource unit is the resource unit where the Q transmission opportunities of the periodic channel are located.

[0089] The resource unit includes one of the following:

[0090] At least one time slot;

[0091] At least one sub-timeslot;

[0092] At least one symbol;

[0093] At least one RB;

[0094] At least one subcarrier.

[0095] The at least one resource unit included in the first resource set is determined according to Q transmission opportunities of the periodic channel:

[0096] In some embodiments, the Q transmission opportunities include one of the following:

[0097] (1) The Q transmission opportunities are the first Q transmission opportunities in the first cycle of the periodic channel;

[0098] (2) The Q transmission opportunities are the first Q transmission opportunities that meet the first condition within the first period of the periodic channel;

[0099] (3) The Q transmission opportunities are the first A transmission opportunities in the first cycle of the periodic channel and the last QA transmission opportunities in the cycle before the first cycle;

[0100] Wherein, A is a non-negative integer, A is less than Q, Q is less than or equal to the number T of transmission opportunities within one period of the periodic channel, and T is a positive integer. In some embodiments, the first condition is used to screen valid uplink transmission opportunities, or to screen transmission opportunities that can be used to transmit the first information, but the meaning of the first condition is not limited thereto.

[0101] In the above-mentioned cases, the unused preconfigured channel resources indicated by the first information are channel resources within the first period.

[0102] In some embodiments, the Q transmission opportunities are Q transmission opportunities within at least one period of a periodic channel.

[0103] Different implementation methods for Q transmission opportunities:

[0104] For (1): the Q transmission opportunities are the first Q transmission opportunities in the first cycle of the periodic channel. FIG3 shows a schematic diagram of the Q transmission opportunities provided by an exemplary embodiment of the present application. For example, taking the transmission opportunity as a CG PUSCH opportunity as an example, the starting position of the first cycle is the starting position of CG PUSCH opportunity 1 (as shown by the dotted line on the left side of FIG3 ), Q is 2, and the two CG PUSCH opportunities are the first two CG PUSCH opportunities in the first cycle. The first resource set includes CG PUSCH opportunity 1 and CG PUSCH opportunity 2. In this example, the unused preconfigured channel resources may be at least one of CG PUSCH opportunity 3 and CG PUSCH opportunity 4.

[0105] FIG4 shows a schematic diagram of a channel resource indication method provided by an exemplary embodiment of the present application. A terminal device receives signaling (RRC or DCI) sent by a network device, thereby obtaining a CG configuration. The CG configuration includes: a first period (CG period) of 16 ms, including four CG PUSCH opportunities within the first period, Q = 2. The first resource set includes CG PUSCH opportunity 1 and CG PUSCH opportunity 2.

[0106] When the terminal device sends CG PUSCH in CG PUSCH opportunity 1 and / or CG PUSCH opportunity 2, the first information carried in the CG PUSCH is used to indicate that CG PUSCH opportunity 3 and / or CG PUSCH opportunity 4 in the first period are not used, used, or to be determined. Not using means that CG PUSCH is not sent on the corresponding CG PUSCH opportunity according to pre-configured parameters.

[0107] When the terminal does not send the pre-configured CG PUSCH in CG PUSCH opportunity 1 and / or CG PUSCH opportunity 2, but sends other uplink channels, such as PUSCH or PUCCH, Figure 5 shows a schematic diagram of a channel resource indication method provided by an exemplary embodiment of the present application, and takes the other uplink channel as a dynamic grant (Dynamic Grant, DG) PUSCH as an example for illustration. The time domain resources occupied by DG PUSCH overlap with the time domain resources included in CG PUSCH opportunity 1 and CG PUSCH opportunity 2. The terminal device sends the first information in DG PUSCH to indicate that CG PUSCH opportunity 3 and / or CG PUSCH opportunity 4 in the first period are not used, used, or to be determined.

[0108] In some embodiments, the network device does not indicate Q in the CG configuration, and Q is assumed to be equal to T by default.

[0109] For (2): the Q transmission opportunities are the first Q transmission opportunities in the first period of the periodic channel that meet the first condition, where the first condition includes at least one of the following:

[0110] The symbols occupied by the transmission opportunity are all uplink symbols;

[0111] The symbols occupied by the transmission opportunity are uplink symbols or flexible symbols;

[0112] All RBs occupied by transmission opportunities are uplink RBs.

[0113] The RBs occupied by the transmission opportunity are uplink RBs, flexible RBs, or RBs in the guard band;

[0114] The symbols occupied by the transmission opportunity do not include downlink symbols;

[0115] The symbols occupied by the transmission opportunity do not include downlink symbols or flexible symbols;

[0116] The symbols occupied by the transmission opportunity do not include the symbols occupied by the synchronization signal;

[0117] The symbols occupied by the transmission opportunity do not include the symbols occupied by the broadcast channel;

[0118] The symbols occupied by the transmission opportunity do not include the symbols occupied by the downlink control channel;

[0119] The RBs occupied by the transmission opportunity do not include downlink RBs;

[0120] The RBs occupied by the transmission opportunity do not include RBs in the guard band or flexible RBs;

[0121] The RBs occupied by transmission opportunities do not include those occupied by synchronization signals.

[0122] The RBs occupied by transmission opportunities do not include those occupied by broadcast channels.

[0123] The RBs occupied by transmission opportunities do not include the RBs occupied by downlink control channels;

[0124] The transmission opportunity is not dropped or cancelled;

[0125] A transmission opportunity is a transmission opportunity that a terminal device actually transmits.

[0126] In some embodiments, since the transmission opportunity is used for uplink transmission, the first condition is met when the occupied symbols are all uplink symbols, or the occupied symbols are uplink symbols or flexible symbols, or the occupied RBs are all uplink RBs, or the occupied RBs are uplink RBs or flexible RBs or RBs within the protection band.

[0127] Among them, uplink symbols and uplink RBs are only used for uplink transmission, flexible symbols and flexible RBs can be used for both uplink and downlink transmission, the guard band is the interval between frequency bands, and the RBs in the guard band can be used for both uplink and downlink transmission, or the RBs in the guard band have no transmission function.

[0128] In some embodiments, the first condition is not met when the occupied symbol is a downlink symbol or a flexible symbol, or the occupied symbol is a symbol occupied by a synchronization signal or a broadcast channel or a downlink control channel, or the occupied RB is an RB within a protection band or a flexible RB, or the occupied RB is an RB occupied by a synchronization signal or a broadcast channel or a downlink control channel.

[0129] Since the transmission content in the synchronization signal, broadcast channel or downlink control channel has been determined, in order to avoid conflicts, the symbols or RBs occupied by the transmission opportunities are discarded or canceled or not used to transmit the first information, wherein the downlink symbols and downlink RBs are only used for downlink transmission.

[0130] In some embodiments, the first condition is satisfied if the transmission opportunity is not discarded or cancelled and the transmission opportunity is a transmission opportunity actually transmitted by the terminal device, ie, the first condition is satisfied if the transmission opportunity can be transmitted or has actually been transmitted.

[0131] For (3): the Q transmission opportunities are the first A transmission opportunities in the first cycle of the periodic channel and the last QA transmission opportunities in the cycle before the first cycle, where A is a non-negative integer and A is less than Q. Figure 6 shows a schematic diagram of Q transmission opportunities provided by an exemplary embodiment of the present application.

[0132] For example, taking the transmission opportunity as a CG PUSCH opportunity as an example, the starting position of the first cycle is the starting position of CG PUSCH opportunity 1, Q is 2, A is 1, and the last transmission opportunity in the cycle before the first cycle is CG PUSCH opportunity 5, that is, the first resource set includes CG PUSCH opportunity 1 and CG PUSCH opportunity 5.

[0133] In some embodiments, the Q transmission opportunities are configured by the network device based on a bitmap, or based on a transmission opportunity index value. For example, taking the transmission opportunity as a CG PUSCH opportunity as an example, 0 indicates that the CG PUSCH opportunity is not configured, 1 indicates that the CG PUSCH opportunity is configured, Q is 2, and in the four CG PUSCH opportunities from CG PUSCH opportunity 1 to CG PUSCH opportunity 4, the value of the bitmap is 1100, that is, the network device configures the first resource set to include CG PUSCH opportunity 1 and CG PUSCH opportunity 2.

[0134] Figure 7 shows a schematic diagram of Q transmission opportunities provided by an exemplary embodiment of the present application. For the case where the Q transmission opportunities are configured by the network device based on the transmission opportunity index value, the transmission opportunity is a CG PUSCH opportunity as an example for explanation. The starting position of the first cycle is the starting position of CG PUSCH opportunity 1, Q is 2, and the two CG PUSCH opportunities are configured by the network device based on the CG PUSCH index value. Taking the configured CG PUSCH index values ​​of 1 and 3 as an example, CG PUSCH index value 1 corresponds to CG PUSCH opportunity 1, and CG PUSCH index value 3 corresponds to CG PUSCH opportunity 3, that is, the network device configures the first resource set including CG PUSCH opportunity 1 and CG PUSCH opportunity 3.

[0135] The at least one resource unit is determined according to the resource unit where at least one transmission opportunity of the periodic channel is located:

[0136] In some embodiments, the at least one resource unit is determined based on a first reference resource unit;

[0137] The first reference resource unit is a resource unit where at least one transmission opportunity of the periodic channel is located.

[0138] In some embodiments, the at least one resource unit is determined based on a first reference resource unit and a second reference resource unit;

[0139] The first reference resource unit and the second reference resource unit are resource units where at least one transmission opportunity of the periodic channel is located.

[0140] In some embodiments, the time domain position of at least one resource unit is located in a first time domain range, and the first time domain range is a time domain range starting from the time domain position of the first reference resource unit to the time domain position of the second reference resource unit.

[0141] In some embodiments, the second reference resource unit is configured by a network device.

[0142] In some embodiments, the at least one resource unit includes at least one of the following:

[0143] First reference resource unit;

[0144] The S resource units following the first reference resource unit;

[0164] FIG8 is a schematic diagram of at least one resource unit provided by an exemplary embodiment of the present application. For example, the transmission opportunity is a CG PUSCH opportunity. The resource unit is a time slot. The starting position of the second cycle is the starting position of CG PUSCH opportunity 1. The first reference resource unit is time slot 1 where CG PUSCH opportunity 1 is located. S is 1, and one continuous resource unit is time slot 2. The at least one resource unit includes the first reference resource unit and the first resource unit after the first reference resource unit, namely, time slot 1 and time slot 2.

[0165] In some embodiments, the at least one resource unit includes consecutive S+1 resource units starting from a first reference resource unit.

[0166] For (2), the first S resource units for uplink transmission after the first reference resource unit include at least one of an uplink symbol and a flexible symbol. The uplink symbol and the flexible symbol can be configured by high-layer signaling or DCI.

[0185] A transmission opportunity is a transmission opportunity that a terminal device actually transmits.

[0186] In some embodiments, since the transmission opportunity is used for uplink transmission, the first condition is met when the occupied symbols are all uplink symbols, or the occupied symbols are uplink symbols or flexible symbols, or the occupied RBs are all uplink RBs, or the occupied RBs are uplink RBs or flexible RBs or RBs within the protection band.

[0190] In some embodiments, the first condition is satisfied if the transmission opportunity is not discarded or cancelled and the transmission opportunity is a transmission opportunity actually transmitted by the terminal device, ie, the first condition is satisfied if the transmission opportunity can be transmitted or has actually been transmitted.

[0191] FIG9 is a schematic diagram of a method for indicating channel resources provided by an exemplary embodiment of the present application. The first resource set is the time slots in which CG PUSCH opportunity 1 and CG PUSCH opportunity 2 are located in the second period, i.e., time slot 1 and time slot 2. When the terminal device sends an uplink channel in time slot 1 and / or time slot 2, the uplink channel may be a preconfigured CG PUSCH, or other PUSCH or PUCCH, and the first information in the uplink channel is used to indicate that CG PUSCH opportunity 3 and / or CG PUSCH opportunity 4 in the second period are not used, used, or to be determined.

[0198] Figure 10 shows a schematic diagram of configuring resource units provided by an exemplary embodiment of the present application. For example, taking a transmission opportunity as a CG PUSCH opportunity as an example, the resource unit is a time slot, the starting position of the second cycle is the starting position of CG PUSCH opportunity 1, the first reference resource unit is time slot 1 where CG PUSCH opportunity 1 is located, S is 1, V is 1, and the two resource units include one resource unit starting from the first reference resource unit and one resource unit before the first reference resource unit, namely, time slot 1 and time slot 2.

[0199] FIG11 is a schematic diagram of a method for indicating channel resources provided by an exemplary embodiment of the present application. The first resource set is the time slots in which CG PUSCH opportunity 1 and CG PUSCH opportunity 5 are located in the second period, i.e., time slot 1 and time slot 2. When the terminal device sends an uplink channel in time slot 1 and / or time slot 2, the uplink channel may be a preconfigured CG PUSCH, or other PUSCH or PUCCH, and the first information in the uplink channel is used to indicate that CG PUSCH opportunity 3 and / or CG PUSCH opportunity 4 in the second period are not used, used, or to be determined.

[0200] In some embodiments, the first resource set is determined based on configuration information, where the configuration information is used to indicate at least one of the following parameters:

[0201] ·cycle;

[0202] The starting time domain unit identifier or time domain offset;

[0203] The starting frequency domain unit identifier or frequency domain offset;

[0204] Number of time domain units;

[0205] Number of frequency domain units;

[0206] Time domain unit pattern;

[0207] Frequency domain unit pattern;

[0208] At least one time domain unit identifier or time domain offset;

[0209] At least one frequency domain unit identifier or frequency domain offset;

[0210] The period is the duration between one first resource set and the next first resource set;

[0211] The starting time domain unit identifier or time domain offset is used to determine the starting point of the first period or the first resource set in the time domain; the starting frequency domain unit identifier or frequency domain offset is used to determine the starting point of the first period or the first resource set in the frequency domain.

[0212] The number of time domain units and the time domain unit pattern are used to represent the distribution characteristics of the time domain units;

[0213] The number of frequency domain units and the frequency domain unit pattern are used to represent the distribution characteristics of the frequency domain units;

[0214] At least one time domain unit identifier or time domain offset corresponds to the starting point of Q transmission opportunities in a period in the time domain; at least one frequency domain unit identifier or frequency domain offset corresponds to the starting point of Q transmission opportunities in a period in the frequency domain.

[0215] Figure 12 shows a schematic diagram of Q transmission opportunities provided by an exemplary embodiment of the present application. The first resource set is determined according to the configuration information. For example, taking the transmission opportunity as a CG PUSCH opportunity as an example, the cycle starting position of the first resource set is the starting position of CG PUSCH opportunity 1 in CG configuration 1, and the cycle length is 16ms. Each cycle includes 2 transmission opportunities. As shown in Figure 12, the first resource set includes CG PUSCH opportunity 1 and CG PUSCH opportunity 2 in CG configuration 1, as well as CG PUSCH opportunity 2 in CG configuration 2 and CG PUSCH opportunity 1 in CG configuration 3.

[0216] Among them, the period of CG configuration 1 is P1, the period of CG configuration 2 is P2, and the period of CG configuration 3 is P3.

[0217] Figure 13 shows a schematic diagram of a channel resource indication method provided by an exemplary embodiment of the present application. The network device configuration period is 16ms, with each period including two time slots. The bit size of the first information can remain unchanged or can be changed according to an agreed rule, but the indication object in different periods is different.

[0218] For example, in the first cycle, the first information may indicate that CG PUSCH opportunity 3 and CG PUSCH opportunity 4 corresponding to CG configuration 1 are not used or used or are to be determined, and in the next cycle, the first information may indicate that CG PUSCH opportunity 1 and CG PUSCH opportunity 2 corresponding to CG configuration 3 are not used or used or are to be determined.

[0219] For the first channel:

[0220] In some embodiments, the first channel is configured by a network device or agreed upon by a communication protocol, including at least one of the following:

[0221] PUCCH;

[0222] ·PUSCH.

[0223] When the first channel is a PUCCH, the first channel carries first information and second information, where the second information includes at least one of the following: feedback information, a scheduling request (SR), and channel-state information (CSI); or,

[0224] When the first channel is a PUSCH, the first channel carries first information and third information, where the third information includes at least one of the following: a transport block (TB), feedback information, and CSI;

[0225] The feedback information includes at least one of the following: a positive acknowledgement (ACK) and a negative acknowledgement (NACK).

[0226] In some embodiments, when the first channel is a PUCCH, the PUCCH is configured to transmit other UCI information. When the PUCCH is configured in the first resource set, the first information is multiplexed into the PUCCH for transmission, and the first information is not independently configured in a PUCCH for transmission.

[0227] In some embodiments, when the first channel is PUSCH, the PUSCH is configured to transmit other UCI information. When the PUSCH is configured in the first resource set, the first information is multiplexed in the PUSCH for transmission, and the first information will not be independently configured with PUSCH for transmission.

[0228] In some embodiments, the network device configures a dedicated channel (PUCCH or PUSCH) to carry the first information. If the dedicated channel does not overlap with other channels, the dedicated channel is the first channel. Furthermore, if it overlaps with other channels, the information carried in the other channels is multiplexed, and the channel carrying the multiplexed information is determined to be the first channel.

[0229] In some embodiments, the starting resource position of the first channel is the starting resource position of the first resource set, or the starting resource position of the first channel is after the starting resource position of the first resource set, or the starting resource position of the first channel is not earlier than the starting resource position of the first resource set, thereby ensuring that the terminal device has sufficient time to generate the first information.

[0230] Regarding the first information:

[0231] In some embodiments, after the first information is encoded, it is mapped to the first channel for transmission, that is, the first information is independently encoded.

[0232] In some embodiments, the fourth information is encoded and mapped to the first channel; wherein the fourth information includes the first information and the fifth information, and the fifth information includes at least one of the following:

[0233] Hybrid Automatic Repeat-reQuest (HARQ) process number information;

[0234] Redundancy Version (RV) information;

[0235] Modulation and Coding Scheme (MCS) information;

[0236] Feedback response information;

[0237] SR;

[0238] ·CSI.

[0239] In some embodiments, when the first channel is a PUSCH configured by high-layer signaling, the fifth information includes HARQ process number information and / or feedback response information; or, when the first channel is a PUSCH scheduled by DCI, the fifth information includes feedback response information.

[0240] In some embodiments, the preconfigured channel resources include at least one of the following:

[0241] CG PUSCH opportunities;

[0242] PUSCH transmission opportunities configured by higher-layer signaling;

[0243] PUCCH resources configured by higher-layer signaling;

[0244] PUSCH or PUCCH indicated by the first DCI;

[0245] The first DCI is transmitted before the first channel.

[0246] In some embodiments, the first information indicates that the unused preconfigured channel resources include: CG PUSCH opportunities that are not used in the first CG configuration; and / or, the unused preconfigured channel resources include CG PUSCH opportunities that are not used in different CG configurations.

[0247] Exemplarily, for unused pre-configured channel resources including CG PUSCH opportunities not used in a first CG configuration, the first information in the first resource set in the first CG configuration is only used to indicate the CG PUSCH opportunities not used in the first CG configuration;

[0248] For unused pre-configured channel resources, including CG PUSCH opportunities that are not used in different CG configurations, when the first resource set is independently configured by a network device, the first resource set includes different CG configurations, and different CG configurations include unused CG PUSCH opportunities; or, the first information in the first resource set directly indicates the CG configuration index value, and further indicates the index value of the CG PUSCH opportunity corresponding to the CG PUSCH opportunity that is not used in the CG configuration.

[0249] In summary, the method provided in this embodiment, by sending a first channel, the first channel carries first information, the first information is used to indicate that the preconfigured channel resources are not used, and the physical resources occupied by the first channel are physical resources in a first resource set, and the first resource set includes at least one resource unit, thereby helping the network device to reallocate unused channel resources to other terminal devices for data transmission, thereby improving data transmission efficiency;

[0250] The method provided in this embodiment further ensures that the transmission opportunity of the terminal device is valid by determining that at least one resource unit is the first Q transmission opportunities that meet the first condition within the first period of the periodic channel;

[0251] The method provided in this embodiment further flexibly controls the transmission position of the first information by configuring the transmission opportunity by the network device, thereby implementing discontinuous indication or reducing UCI overhead.

[0252] The method provided in this embodiment also configures the first resource set by the network device so that the configuration of the first resource set is not bound to a fixed CG configuration, which has a working advantage when the terminal device is configured with multiple CG configurations.
