In some embodiments of the present application, "NR" may also be referred to as a 5G NR system or a 5G system. Among them, the 5G mobile communication system may include non-standalone networking (NSA) and / or standalone networking (SA).

[0057] The technical solutions provided in the embodiments of the present application can also be applied to machine type communication (MTC), long term evolution technology for machine-to-machine communication (LTE-M), device-to-device (D2D) network, machine-to-machine (M2M) network, Internet of Things (IoT) network or other networks. Among them, the IoT network can include, for example, the Internet of Vehicles. Among them, the communication mode in the Internet of Vehicles system is collectively referred to as vehicle to other devices (Vehicle to X, V2X, X can represent anything), for example, the V2X can include: vehicle to vehicle (V2V) communication, vehicle to infrastructure (V2I) communication, vehicle to pedestrian communication (V2P) or vehicle to network (V2N) communication, etc.

[0058] The terminal device 120 and the terminal device 130 communicate with each other through a direct communication interface, such as a PC5 interface. For example, the terminal device 120 and the terminal device 130 are both within the network coverage and located in the same cell, or the terminal device 120 and the terminal device 130 are both within the network coverage but located in different cells, or the terminal device 120 is within the network coverage but the terminal device 130 is outside the network coverage.

[0059] Network device 110 and terminal device 120 communicate with each other via an air interface technology, such as the Uu interface. There are two communication scenarios between network device 110 and terminal device 120: uplink (UL) transmission and downlink (DL) transmission. Uplink transmission refers to terminal device 120 sending signals (at least one of an uplink channel, uplink signaling, uplink data, and uplink signals) to network device 110; downlink transmission refers to network device 110 sending signals (at least one of an uplink channel, uplink signaling, uplink data, and uplink signals) to terminal device 120.

[0060] Bandwidth Part (BWP):

[0061] A BWP is an access bandwidth that is smaller than both the cell system bandwidth and the terminal bandwidth capability. A terminal device can operate with a smaller BWP when not transmitting data and a larger BWP when transmitting data. Optionally, a terminal device can activate one downlink BWP and one uplink BWP on the same carrier at the same time.

[0062] As shown in Figure 2, during relatively idle periods, the terminal device's active uplink BWP is BWP1, which has a narrow frequency domain width and is relatively power-efficient. When the terminal device needs to send an uplink channel or uplink signal, it can switch the active uplink BWP from BWP1 to BWP2, which has a wider frequency domain width and can transmit uplink channels or uplink signals at a high rate.

[0063] In some embodiments, "activating an uplink BWP" may be simply referred to as activating a BWP or an uplink BWP.

[0064] SubBand non-overlapping Full Duplex (SBFD):

[0065] To overcome the problems of weak uplink coverage, long uplink latency, and insufficient uplink capacity caused by limited uplink (UL) resource allocation in Time Division Duplexing (TDD) technology, SBFD technology was proposed. SBFD technology allows data to be simultaneously transmitted and received on different subbands within the same subframe, time slot, or symbol. SBFD is primarily used on the network equipment side, while the user equipment (UE) side maintains its current state, specifically only transmitting or receiving data within the same subframe, time slot, or symbol. SBFD is also known as Cross Division Duplex (XDD) technology.

[0066] Exemplarily, the SBFD technology, as shown in Figure 3, configures a portion of the frequency domain resources corresponding to a downlink (DL) time domain unit as an uplink subband. As shown in part (a) of Figure 3, the middle subband of the frequency domain resources corresponding to a downlink time domain unit is configured as an uplink subband. Alternatively, as shown in part (b) of Figure 3, the upper subband of the frequency domain resources corresponding to a downlink time domain unit is configured as an uplink subband.

[0067] Generally speaking, SBFD operations meet the following requirements:

[0068] SBFD operates within one TDD carrier.

[0069] The SBFD solution is designed within a single uplink and downlink BWP pair with aligned center frequencies.

[0070] In a TDD carrier, an SBFD symbol (including a traditional uplink symbol) has at most one uplink subband. This uplink subband can be located in the middle of the TDD carrier or on both sides of the TDD carrier.

[0071] Furthermore, to maintain compatibility with symbol-level TDD uplink and downlink configurations, a time slot is allowed to include both SBFD symbols and non-SBFD symbols. Figure 3 shows a time slot diagram provided by related art. A portion of the frequency domain resources corresponding to the downlink symbols (D) and flexible symbols (F) in a time slot shown in Figure 4 is configured as an uplink subband.

[0072] Frequent switching between SBFD and non-SBFD symbols can increase implementation complexity and cause transmission interruptions. To avoid frequent SBFD symbol switching, a TDD cycle is specified to contain at most two transition points: one from a non-SBFD symbol to an SBFD symbol, and the other from an SBFD symbol to a non-SBFD symbol. For example, the transition point is between symbols 8 and 9 in Figure 2. A transition point can be at a slot boundary or within a slot.

[0073] Related technologies stipulate that uplink transmission can only be limited to the uplink sub-band, and downlink reception can only be limited to the downlink sub-band.

[0074] The contention-based random access process is introduced as follows:

[0075] The terminal device supports a contention-based random access process. FIG5 shows a schematic diagram of a contention-based random access process provided by related art, which includes the following steps:

[0076] Step 1: The terminal device sends message 1 (msg1): random access preamble code to the network device.

[0077] The terminal device sends the selected random access preamble on the time-frequency resources of the selected physical random access channel (PRACH). Based on the random access preamble, the network device can estimate the uplink delay and the grant size required for the terminal device to transmit message 3.

[0078] Step 2: The network device sends message 2 (msg2): Random Access Response (RAR) to the terminal device.

[0079] After sending message 1 (msg1), the terminal device opens a random access response window (RAR window) and monitors the physical downlink control channel (PDCCH) within the random access response window. The PDCCH is the DCI scrambled with the random access radio network temporary identifier (RA-RNTI).

[0080] After successfully monitoring the RA-RNTI-scrambled DCI, the terminal device can obtain the physical downlink shared channel (PDSCH) scheduled by the DCI, and the PDSCH includes the RAR.

[0081] The RAR includes: a backoff indicator (BI), which is used to indicate the backoff time for retransmitting message 1; a random access preamble IDentifier (RAPID), which is used to indicate the random access preamble code; a timing advance group (TAG), which is used to adjust the uplink timing; an uplink grant, which is used to indicate the uplink resources for scheduling message 3; and a temporary cell-radio network temporary identity (Temporary C-RNTI), which is used to scramble the PDCCH (initial access) of message 4.

[0082] Step 3: The terminal device sends message 3 (msg3): Scheduled Transmission (ST) to the network device.

[0083] Message 3 is primarily used to notify the network device of the event that triggered the random access procedure. For example, if the event is the initial random access procedure, Message 3 will carry the terminal device identification (ID) and establishment cause; if the event is Radio Resource Control (RRC) reestablishment, it will carry the connected terminal device ID and establishment cause. Furthermore, the terminal device ID or connected terminal device ID carried in Message 3 can resolve contention conflicts in step 240.

[0084] Step 4: The network device sends message 4 (msg4): contention resolution message to the terminal device.

[0085] Message 4 has two functions. First, message 4 can be used to resolve contention conflicts. Second, message 4 is a message for the network device to transmit RRC configuration to the terminal device.

[0086] Resolving contention conflicts means that the terminal device receives the PDSCH of message 4 and schedules it by matching the Common Control Channel Signal Distribution Unit (CCCH SDU) in the PDSCH. There are two scheduling methods:

[0087] 1. If the terminal device carries the temporary C-RNTI in message 3, message 4 is scheduled using the PDCCH scrambled with the temporary C-RNTI;

[0088] 2. The terminal device does not carry the temporary C-RNTI in message 3. For example, if the random access process is initial access, message 4 uses the PDCCH scrambled by the temporary C-RNTI for scheduling.

[0089] PUSCH (Msg3) scheduling based on RAR uplink grant (UL grant):

[0090] As shown in Figure 4, the terminal device monitors the DCI scrambled by the RA-RNTI in the random access response window. This DCI is used to schedule the RAR, which contains an uplink grant. The contents of this uplink grant are shown in Table 1 below and are used to schedule the transmission of Message 3.

[0091] Table 1

[0092] As can be seen from Table 1, the RAR uplink grant field includes a 1-bit frequency hopping flag, which is used to indicate whether frequency hopping is used for transmission of message 3. The transmission parameters of message 3 are determined by the uplink BWP of the terminal.

[0093] Message 4 and HARQ-ACK feedback:

[0094] After the terminal device receives Message 3, the network device needs to send Msg 4 to specify the terminal device that won the competition. Subsequently, the terminal device that won the competition performs HARQ-ACK feedback of Message 4 on the PUCCH (not shown in Figure 5).

[0095] Message 4 is also transmitted using frequency hopping transmission. The transmission parameters of Message 4 are determined by the uplink BWP of the terminal.

[0096] The introduction of SBFD timeslots may cause issues with the frequency-hopping transmission of Messages 3 and 4. As shown in Figure 6, for the first and second hops in a frequency-hopping transmission, because the transmission parameter scheme used in related art does not account for SBFD timeslots, the frequency domain resources for the first and / or second hops may be located outside the uplink subband. As shown in the example in Figure 5, the frequency domain resources for the second hop fall within the downlink subband, making the second hop unable to be transmitted.

[0097] FIG7 shows a flow chart of an uplink transmission method provided by an exemplary embodiment of the present application. The method is executed by a terminal device and includes:

[0098] Step 120: Send an uplink channel or an uplink signal based on transmission parameters, where the transmission parameters are determined based on parameters related to the first frequency domain bandwidth;

[0099] The first frequency domain bandwidth is a subset of the second frequency domain bandwidth. The second frequency domain bandwidth is the uplink bandwidth configured by the network device for the terminal device, and the first frequency domain bandwidth is the actual available uplink bandwidth determined in the second frequency domain bandwidth based on the configuration of the first duplex mode or the first time domain resource type. Exemplarily, the second frequency domain bandwidth is the uplink BWP of the terminal device. Exemplarily, the first duplex mode or the first time domain resource type is SBFD. In some embodiments, the first frequency domain bandwidth is a true subset of the second frequency domain bandwidth, that is, the first frequency domain bandwidth belongs to the second frequency domain bandwidth and is smaller than the second frequency domain bandwidth.

[0100] In some embodiments, the uplink BWP is an uplink BWP activated for uplink transmissions by the terminal device. The first frequency-domain bandwidth is the entire bandwidth or a portion of the uplink BWP. Due to different configurations of different first time-domain resource types or different available uplink subbands within different time-domain resource types, the first frequency-domain bandwidth may dynamically change even for the same terminal device.

[0101] In some embodiments, the first frequency domain bandwidth may be understood as an available subband in an uplink BWP, an available uplink subband, an actually available subband, or an actually available uplink subband.

[0102] To sum up, the method provided in this embodiment determines the transmission parameters by determining the transmission parameters based on the relevant parameters of the first frequency domain bandwidth, and the first frequency domain bandwidth is a subset of the second frequency domain bandwidth. Compared with the method of using the second frequency domain bandwidth to determine the transmission parameters in the related technology, it can adapt to the impact of the new duplex mode on the actual available uplink bandwidth of the terminal device, and ensure that the uplink transmission of the terminal can fall within the available uplink resources.

[0103] FIG8 shows a flow chart of an uplink transmission method provided by an exemplary embodiment of the present application. The method is executed by a network device and includes:

[0104] Step 220: receiving an uplink channel or an uplink signal based on a transmission parameter, where the transmission parameter is determined based on parameters related to the first frequency domain bandwidth of the terminal device;

[0105] The first frequency domain bandwidth is a subset of the second frequency domain bandwidth. The second frequency domain bandwidth is the uplink bandwidth configured by the network device for the terminal device, and the first frequency domain bandwidth is the actual available uplink bandwidth determined in the second frequency domain bandwidth based on the configuration of the first duplex mode or the first time domain resource type. Exemplarily, the second frequency domain bandwidth is the uplink BWP of the terminal device. Exemplarily, the first duplex mode or the first time domain resource type is SBFD. In some embodiments, the first frequency domain bandwidth is a true subset of the second frequency domain bandwidth, that is, the first frequency domain bandwidth belongs to the second frequency domain bandwidth and is smaller than the second frequency domain bandwidth.

[0106] In some embodiments, the uplink BWP is an uplink BWP activated for uplink transmissions by the terminal device. The first frequency-domain bandwidth is the entire bandwidth or a portion of the uplink BWP. Due to differences in available uplink subbands in different duplex modes or time-domain resource types, the first frequency-domain bandwidth may dynamically change even for the same terminal device.

[0107] In some embodiments, the first frequency domain bandwidth may be understood as an available subband in an uplink BWP, an available uplink subband, an actually available subband, or an actually available uplink subband.

[0108] To sum up, the method provided in this embodiment determines the transmission parameters by determining the transmission parameters based on the relevant parameters of the first frequency domain bandwidth, and the first frequency domain bandwidth is a subset of the second frequency domain bandwidth. Compared with the method of using the second frequency domain bandwidth to determine the transmission parameters in the related technology, it can adapt to the impact of the new duplex mode on the actual available uplink bandwidth of the terminal device. Even if the actual available uplink bandwidth of the terminal device is smaller than the second frequency domain bandwidth, the transmission parameters can be accurately determined.

[0109] In an optional embodiment based on FIG. 7 or FIG. 8 , the first frequency-domain bandwidth is a portion of an available subband within an uplink BWP. The first frequency-domain bandwidth is the actual available uplink bandwidth of the terminal device. The first frequency-domain bandwidth includes at least one of the following: an uplink subband; an uplink BWP; an actual subband; the intersection of an uplink subband and an uplink BWP; an actual uplink subband, which is the intersection of an uplink subband (also called a nominal subband) and an uplink BWP; an actual uplink BWP, which is the intersection of an uplink subband and an uplink BWP; an uplink subband portion within an uplink BWP; an available uplink subband portion within an uplink BWP; an uplink subband portion within an uplink BWP within the first time-domain resource type; or an available uplink subband portion within an uplink BWP within the first time-domain resource type.

[0110] In some embodiments, the first frequency domain bandwidth is the intersection of the second and third frequency domain bandwidths. The second frequency domain bandwidth is the activated uplink bandwidth configured for the terminal device by the network device or communication protocol. The third frequency domain bandwidth is the uplink subband of the currently used duplex mode or time domain resource type, typically determined by the relevant configuration of the cellular communication system. The intersection of the second and third frequency domain bandwidths is the actual available uplink bandwidth of the terminal device, i.e., the first frequency domain bandwidth.

[0111] The second frequency domain bandwidth may be referred to as any of the following: uplink BWP, uplink bandwidth, activated uplink BWP, activated BWP, activated uplink bandwidth, and the like. The third frequency domain bandwidth may be referred to as any of the following: subband, uplink subband, nominal uplink subband, uplink subband within a frame structure, uplink subband within a first time domain resource type, and the like. The first time domain resource type is a time domain resource type that includes an uplink subband and / or a downlink subband. For example, the first time domain resource type is at least one of an SBFD symbol, an SBFD time slot, and an SBFD subframe.

[0112] The second frequency domain bandwidth is the uplink BWP, the third frequency domain bandwidth is the uplink subband, and the first frequency domain bandwidth is the intersection of the uplink subband and the uplink BWP. Since there are many possibilities for the positions of the uplink BWP and the uplink subband, an exemplary representation is as follows:

[0113] As shown in Figure 9, in some examples, the uplink subband falls completely within the uplink BWP, and the first frequency domain bandwidth is the frequency domain bandwidth corresponding to the uplink subband. As shown in Figure 10, in some embodiments, the uplink subband does not fall completely within the uplink BWP, and the first frequency domain bandwidth is the intersection of the uplink subband and the uplink BWP. As shown in Figure 11, in some embodiments, the uplink subband and the uplink BWP are identical, and the first frequency domain bandwidth is the frequency domain bandwidth corresponding to the uplink subband or the uplink BWP.

[0114] In some embodiments, the transmission parameters of the uplink transmission are determined based on parameters related to the first frequency domain bandwidth. The parameters related to the first frequency domain bandwidth include at least one of the following: a frequency domain starting position of the first frequency domain bandwidth and a size of the first frequency domain bandwidth.

[0115] In some embodiments, the frequency domain starting position of the first frequency domain bandwidth is the starting position in the frequency domain dimension. The starting position can be represented by "first reference point + offset value". The first reference point can be preconfigured by the network device or predefined by the communication protocol. The first reference point can be any one of the frequency domain starting position of the system bandwidth, the frequency domain starting position of the current carrier (point A or CRB 0), the frequency domain starting position of the uplink BWP, and the frequency domain starting position of the uplink subband.

[0116] In some embodiments, the size of the first frequency domain bandwidth may be expressed using frequency domain units, which include but are not limited to at least one of a physical resource block (PRB), a resource block (RB), a resource element (RE), and a PRB group.

[0117] In an optional embodiment based on FIG. 7 or FIG. 8 , the transmission parameters of the uplink transmission include at least one of parameters related to frequency hopping transmission and parameters related to uplink resources.

[0118] The relevant parameters of frequency hopping transmission include at least one of the following: the size of the frequency hopping offset; the number of bits of the first indication information, wherein the first indication information is used to indicate the size of the frequency hopping offset; the frequency domain resource allocation field; the frequency domain starting position of each hop; the frequency domain starting position of the first hop; and the frequency domain starting position of the second hop.

[0119] The size of the frequency hopping offset refers to the offset between the frequency domain starting positions of two adjacent hops. As shown in Figure 12, the offset between the frequency domain starting position of the first hop and the frequency domain starting position of the second hop is the size of the frequency hopping offset. The size of the frequency hopping offset can be calculated using frequency domain units. Frequency domain units include, but are not limited to, at least one of: a physical resource block (PRB), a resource block (RB), a resource element (RE), and a PRB group.

[0120] The number of bits of the first indication information is dynamically variable. For example, the frequency domain resource allocation (FDRA) field of the RAR uplink authorization includes several bits (i.e., the first indication information), such as shown in Figure 12. Assuming that the FDRA field is 14 bits, the 1st to 2nd bits in descending order are used to indicate the above-mentioned frequency hopping offset. The number of these several bits may be one of multiple candidate bit numbers (1 or 2), and the actual number of bits needs to be determined based on the first frequency domain bandwidth.

[0121] The frequency domain resource allocation field is used to indicate the frequency domain resource location of the PUSCH or PUCCH. Exemplarily, the frequency domain resource allocation field in the RAR uplink grant includes 14 bits. The bits of these 14 bits, excluding the first indication information, are used to indicate the frequency domain resource location of the PUSCH or PUCCH, as shown in Figure 13.

[0122] Each hop in frequency hopping transmission has its own corresponding frequency domain starting position. Frequency hopping transmission can be periodic or aperiodic. As shown in Figure 12, frequency hopping transmission occurs with a periodic first and second hop. The frequency domain starting position of each hop can be determined based on the periodic frequency domain starting position of the first and second hops.

[0123] The relevant parameters of the uplink resource include parameters for determining the uplink resource or uplink resource set. The uplink resource can be a PUCCH resource or a PDCCH resource. For example, the offset parameter of the PUCCH resource relative to the second reference point. Optionally, the second reference point can be pre-configured by the network device or pre-defined by the communication protocol. The second reference point can be any one of the frequency domain starting position of the system bandwidth, the frequency domain starting position of the current carrier (point A or CRB0), the frequency domain starting position of the uplink BWP, the frequency domain starting position of the uplink subband, and the frequency domain starting position of the first frequency domain bandwidth.

[0124] In the optional embodiments based on Figures 7 or 8 , uplink transmission is used to transmit uplink channels and / or uplink signals. Uplink channels include at least one of the PUSCH and the PUCCH. Uplink signals include at least one of uplink signaling, uplink data, and an uplink reference signal. Exemplarily, uplink signals include Hybrid Automatic Repeat Request-ACK (HARQ-ACK) for Message 3 and Message 4 in the random access procedure.

[0125] Different methods for determining transmission parameters are introduced separately (the following methods can be combined arbitrarily):

[0126] 1. The size of the frequency hopping offset;

[0127] In some embodiments, the size of the frequency hopping offset is determined based on at least one of the following: one-half of the first frequency domain bandwidth; one-quarter of the first frequency domain bandwidth.

[0128] In some embodiments, the size of the frequency hopping offset is indicated by the first indication information and / or the second indication information; for example, the size of the frequency hopping offset is indicated by a code point carried by the first indication information, with different code points corresponding to different sizes of the frequency hopping offset; the second indication information is used to schedule transmission of an uplink channel or uplink signal, and the second indication information includes the first indication information. Optionally, the second indication information is a RAR or a DCI.

[0129] In an example, taking the uplink signal as message 3 in the random access process as an example, the correspondence between the number of bits of the first indication information, different code points, and different frequency hopping offsets is shown in Table 2:

[0130] Table 2

[0131] Among them, the first indication information N UL,hop 1 bit or 2 bits, the first indication information N UL,hop When it is 1 bit, it includes 2 code points: 0 and 1; the first indication information N UL,hop When it is 2 bits, it includes 4 code points: 00, 01, 10, and 11. Indicates the size of the first frequency domain bandwidth. Indicates a value that is rounded down.

[0132] For example, the terminal device receives the first indication information sent by the network device, and determines the size of the frequency hopping offset based on the code point indicated by the first indication information and the corresponding relationship shown in Table 2 above.

[0133] Since the frequency hopping offset is determined based on the size of the first frequency domain bandwidth, such as half or one quarter of the first frequency domain bandwidth, it can be guaranteed to a certain extent that the frequency domain resource position of the second hop is still within the first frequency domain bandwidth and will not exceed the first frequency domain bandwidth.

[0134] In some embodiments, when the time domain resources occupied by the current hop are of the first time domain resource type (SBFD), the size of the frequency hopping offset is determined based on parameters related to the first frequency domain bandwidth; when the time domain resources occupied by the current hop are of the second time domain resource type (non-SBFD), the size of the frequency hopping offset is determined based on parameters related to the second frequency domain bandwidth. When the size of the frequency hopping offset is determined based on parameters related to the second frequency domain bandwidth, the first frequency domain bandwidth in Table 2 above can be replaced with the second frequency domain bandwidth.

[0135] 2. The number of bits of the first indication information;

[0136] The first indication information is used to indicate the size of the frequency hopping offset.

[0137] In some embodiments, the number of bits of the first indication information is determined based on a size relationship between the first frequency domain bandwidth and a first threshold.

[0138] In some embodiments, when the size of the first frequency domain bandwidth is less than the first threshold, the number of bits of the first indication information is the first number; and / or, when the size of the first frequency domain bandwidth is greater than or equal to the first threshold, the number of bits of the first indication information is the second number.

[0139] Table 3

[0140] in, Indicates the size of the first frequency domain bandwidth. Indicates a value that is rounded down.

[0141] Taking the first threshold of 50 PRBs as an example, when the size of the first frequency domain bandwidth is less than 50, the number of bits of the first indication information is 1 bit; when the size of the first frequency domain bandwidth is greater than or equal to 50, the number of bits of the first indication information is 2 bits.

[0142] As shown in Figure 11, since the first indication information is included in the FDRA field, if the number of bits of the first indication information is not accurately determined, it may cause an incorrect interpretation result. By clarifying that the number of bits of the first indication information is determined based on the size of the first frequency domain bandwidth, the accuracy of the determination of the first indication information can be guaranteed. In addition, the number of bits of the first indication information is determined based on the size of the first frequency domain bandwidth, which can save the number of bits required for the first indication information to a certain extent, that is, more bits are opened up for indicating the position of the uplink transmission frequency domain bandwidth, making the indication more accurate.

[0143] Of course, in some other embodiments, the number of bits of the first indication information is determined based on the size relationship between the second frequency domain bandwidth and the first threshold.

[0144] In some embodiments, when the size of the second frequency domain bandwidth is less than the first threshold, the number of bits of the first indication information is the first number; and / or, when the size of the second frequency domain bandwidth is greater than or equal to the first threshold, the number of bits of the first indication information is the second number.

[0145] Table 4

[0146] in, Indicates the size of the second frequency domain bandwidth. Indicates a value that is rounded down.

[0147] Taking the first threshold of 50 PRBs as an example, when the size of the second frequency domain bandwidth is less than 50, the number of bits of the first indication information is 1 bit; when the size of the second frequency domain bandwidth is greater than or equal to 50, the number of bits of the first indication information is 2 bits.

[0148] As shown in Figure 13, since the first indication information is included in the FDRA field, inaccurate determination of the number of bits in the first indication information may lead to erroneous interpretation results. By specifying that the number of bits in the first indication information is determined based on the size of the second frequency domain bandwidth, the accuracy of the determination of the first indication information can be guaranteed. Furthermore, by determining the number of bits in the first indication information based on the size of the second frequency domain bandwidth, existing technologies can be reused to the greatest extent possible, with minimal protocol modifications.

[0149] It should be noted that the above two methods can be used in combination or separately. For example, in the case of both SBFD time slots and non-SBFD time slots, when the current time slot is SBFD (that is, the first time domain resource type), the number of bits of the first indication information is determined based on the size relationship between the size of the first frequency domain bandwidth and the first threshold; when the current time slot is non-SBFD (that is, the second time domain resource type), the number of bits of the first indication information is determined based on the size relationship between the size of the second frequency domain bandwidth and the first threshold. For another example, regardless of whether the current time slot is SBFD or non-SBFD, the number of bits of the first indication information is always determined based on the size relationship between the size of the first frequency domain bandwidth and the first threshold. For another example, regardless of whether the current time slot is SBFD or non-SBFD, the number of bits of the first indication information is always determined based on the size relationship between the size of the second frequency domain bandwidth and the first threshold.

[0150] 3. Frequency domain resource allocation field;

[0151] In some embodiments, the frequency domain resource allocation field is processed based on the relationship between the size of the first frequency domain bandwidth and the second threshold. Taking the second threshold as 180 PRBs as an example, when the size of the first frequency domain bandwidth is less than 180, the frequency domain resource allocation field is processed using the first method; when the size of the first frequency domain bandwidth is greater than or equal to 180, the frequency domain resource allocation field is processed using the second method.

[0152] The first method includes: truncating the bit sequence in the frequency domain resource allocation field based on the size of the first frequency domain bandwidth to obtain a truncated frequency domain resource sub-field (or a truncated frequency domain resource allocation field, or truncated frequency domain resource allocation indication information); the second method includes: extending the bit sequence in the frequency domain resource allocation field based on the size of the first frequency domain bandwidth to obtain an extended frequency domain resource allocation field (or an extended frequency domain resource allocation field, or an extended frequency domain resource allocation indication information). The frequency domain resource allocation field can be referred to as the FDRA field.

[0153] In some embodiments, the FDRA field includes first indication information. The first method includes:

[0154] The minimum value of the FDRA field Bit truncation;

[0155] And / or, the second method includes: inserting a first number of most significant bits after the first indication information in the FDRA field, the first value being Subtract the difference from M, where M is the preset value.

[0156] Exemplary interpretation of the 14-bit FDRA field in an RAR uplink grant:

[0157] If the size of the first frequency domain bandwidth PRB, the lowest value of the FDRA field Bit truncation, according to the interpretation method of DCI format 0_0 FDRA in communication protocol TS 38.212, interpret the truncated FDRA field, as shown in Figure 14;

[0158] Otherwise: the first indication information N in the FDRA field UL,hop After the bit, insert The most significant bits are set to 0, and the extended FDRA field is interpreted according to the interpretation of DCI format 0_0 FDRA in TS 38.212, as shown in Figure 15. The expansion process is illustrated by taking as an example that M is 17, M is 14, and the first number is 3.

[0159] Through the above approach, it is possible to ensure that message 3 falls within the first frequency domain bandwidth after frequency hopping, and calculate the actual number of bits required for FDRA based on the size of the first frequency domain bandwidth, so that the number of bits allocated in the frequency domain resources is accurately determined. This is more flexible when the bandwidth of the uplink BWP is large.

[0160] It should be noted that when the occupied time domain resources are of the first time domain resource type (SBFD), the frequency domain resource allocation is processed in the above manner, that is, it is determined based on the relevant parameters of the first frequency domain bandwidth. When the occupied time domain resources are of the second time domain resource type (non-SBFD), the frequency domain resource allocation is determined based on the relevant parameters of the second frequency domain bandwidth. For example:

[0161] If the size of the first frequency domain bandwidth PRB, the lowest value of the FDRA field Bit truncation, interpret the truncated FDRA field according to the interpretation method of DCI format 0_0 FDRA in communication protocol TS 38.212;

[0162] Otherwise: the first indication information N in the FDRA field UL,hop After the bit, insert The most significant bits are set to 0, and the extended FDRA field is interpreted according to the interpretation of DCI format 0_0 FDRA in TS 38.212. The expansion process is illustrated by taking as an example that M is 17, M is 14, and the first number is 3.

[0163] in, The symbol for rounding up.

[0164] 4. An offset value parameter used to determine an uplink channel or a resource set corresponding to an uplink channel;

[0165] The offset value parameter is an offset of the frequency domain starting position of the resource set relative to the frequency domain starting position of the first frequency domain bandwidth. The offset value parameter can be represented or calculated using a frequency domain unit, such as the number of PRBs.

[0166] Taking the uplink channel as an example, the PUCCH used for HARQ-ACK feedback of message 4, the frequency domain starting position of the PUCCH resource set is determined based on the offset value parameter. The offset value parameter is the offset of the frequency domain starting position of the PUCCH resource set relative to the frequency domain starting position of the first frequency domain bandwidth, as shown in Figure 16.

[0167] In some embodiments, the size of the offset value parameter is determined based on the size of the first frequency domain bandwidth.

[0168] Table 5

[0169] Table 5 shows the common PUCCH resource set method. The index is indicated by the configuration signaling sent by the network device, such as Radio Resource Control (RRC) signaling. The parameters in the fifth column are the offset parameters mentioned above.

[0170] In some embodiments, SBFD time slots and non-SBFD time slots share the same Table 5. When the symbol containing the PUCCH resource is an SBFD symbol, the offset value parameter is the offset of the frequency domain starting position of the resource set relative to the frequency domain starting position of the first frequency domain bandwidth. When the symbol containing the PUCCH resource is a non-SBFD symbol, the offset value parameter is the offset of the frequency domain starting position of the resource set relative to the frequency domain starting position of the second frequency domain bandwidth. In other words, the offset value parameter is interpreted with reference to Table 5 for SBFD symbols and with reference to Table 6 for non-SBFD time slots.

[0171] Table 6

[0172] in, is the size of the second frequency domain bandwidth, It is the floor value of one quarter of the second frequency domain bandwidth.

[0173] 5. Frequency domain starting position of each hop / first hop / second hop.

[0174] In some embodiments, taking the uplink channel as a PUSCH as an example, the frequency domain starting position of the second hop is determined according to at least one of the following:

[0175] The size of the frequency hopping offset; the size of the first frequency domain bandwidth; and second indication information, where the second indication information is used to schedule an uplink channel or an uplink signal. Optionally, the second indication information is a RAR uplink grant.

[0176] In some embodiments, the second indication information includes the first indication information, and the size of the frequency hopping offset is indicated by the code point carried by the first indication information, and different code points correspond to different sizes of the frequency hopping offset: the number of bits of the first indication information is determined based on the size of the first frequency domain bandwidth or the size of the second frequency domain bandwidth.

[0177] Schematically, for the frequency hopping in the time slot of message 3, as shown in FIG16 , the frequency domain starting position (such as the starting RB) of each hop is RB start for:

[0178] In which, when it is the first hop, i=0, and when it is the second hop, i=1. start It is obtained through the FDRA of PUSCH in the RAR uplink authorization, RB offset According to Table 3 or Table 4, and the first indication information N UL,hop Commonly obtained.

[0179] For the inter-slot frequency hopping of Msg 3, in the time slot The starting position of the frequency domain (such as the starting RB) for:

[0180] In some embodiments, taking the uplink channel as an example, the frequency domain starting position of each hop, the frequency domain starting position of the first hop, and the frequency domain starting position of the second hop are determined based on at least one of an offset value parameter, a size of the first frequency domain bandwidth, and a frequency domain starting position of the first frequency domain bandwidth. The offset value parameter is an offset of the frequency domain starting position of the PUCCH resource set relative to the frequency domain starting position of the first frequency domain bandwidth.

[0181] In some embodiments, the offset value parameter is determined based on the size of the first frequency domain bandwidth.

[0182] In some embodiments, the frequency domain starting position occupied by each hop / first hop / second hop is determined based on the index corresponding to the PUCCH resource set, the offset value parameter, the number of PRBs contained in the PUCCH resource set, the initial cyclic shift index, the total number of initial cyclic shift indices, and at least one of the first.

[0183] In some embodiments, the frequency domain starting position occupied by each hop is determined based on the index corresponding to the PUCCH resource set. For example, When , the first determination method is used; When , the second determination method is used.

[0184] In some embodiments, the first method for determining the frequency domain starting position occupied by the first hop includes: determining based on the sum of a first value and a second value. The first value is related to the offset value parameter and the number of PRBs included in the PUCCH resource set, and the second value is related to the index corresponding to the PUCCH resource set, the total number of initial cyclic shift indices, and the number of PRBs included in the PUCCH resource set. For example, the first value is The second value is

[0185] In some embodiments, the second method for determining the frequency domain starting position occupied by the first hop includes: subtracting the difference between the first value and the fourth value from the third value to determine the first frequency domain bandwidth. The first value is related to the offset parameter and the number of PRBs included in the PUCCH resource set. For example, the first value is The fourth value is related to the total number of indices corresponding to the PUCCH resource set and the initial cyclic shift index. For example, the fourth value is

[0186] In some embodiments, the first method for determining the frequency domain starting position occupied by the second hop includes: determining the frequency domain starting position based on the third value minus the difference between the first value and the fifth value. The third value is the size of the first frequency domain bandwidth. The first value is related to the offset parameter and the number of PRBs included in the PUCCH resource set. For example, the first value is The fifth value is related to the index corresponding to the PUCCH resource set, the total number of initial cyclic shift indices, and the number of PRBs contained in the PUCCH resource. For example, the fifth value is

[0187] In some embodiments, the second method for determining the frequency domain starting position occupied by the second hop includes: determining based on the sum of the first value and the sixth value. The first value is related to the offset value parameter and the number of PRBs included in the PUCCH resource set, and the sixth value is related to the index corresponding to the PUCCH resource set, the total number of initial cyclic shift indices, and the number of PRBs included in the PUCCH resource set. For example, the first value is The sixth value is

[0188] In an example:

[0189] For the frequency hopping transmission of HARQ-ACK of Msg 4, the RBs occupied by each hop are determined as follows:

[0190] -for The lowest RPB index of the first hop is The lowest RPB index of the second hop is The initial cyclic shift index of PUCCH is (r PUCCH -8)modN CS .

[0191] -for The lowest RPB index of the first hop is The lowest RPB index of the second hop is Initial cyclic shift of PUCCH

[0192] Index is r PUCCH modN CS .

[0193] -in:

[0194] -N CS is the total number of initial cyclic shift indices contained in the cyclic shift index set field in Table 5;

[0195] -N RB is the number of PRBs included in the PUCCH resource;

[0196] -r PUCCH The index corresponding to the PUCCH resource set is indicated by higher-layer signaling, such as RRC signaling;

[0197] - Indicates the offset of the frequency domain starting position of the PUCCH resource set relative to the lowest PRB of the first frequency domain bandwidth.

[0198] In some embodiments, when the time domain resources occupied by the current hop are of the first time domain resource type (SBFD), it is determined based on the relevant parameters of the first frequency domain bandwidth; when the time domain resources occupied by the current hop are of the second time domain resource type (non-SBFD), it is determined based on the relevant parameters of the second frequency domain bandwidth.

[0199] Optionally, in various embodiments of the present application, all time domain resources corresponding to the uplink channel or uplink signal are of the first time domain resource type, such as SBFD time slots. Alternatively, part of the time domain resources corresponding to the uplink channel or uplink signal are of the first time domain resource type, such as SBFD time slots, and the other part are of the second time domain resource type, such as non-SBFD time slots. When the occupied time domain resources are of the first time domain resource type (SBFD), the transmission parameters are determined based on the relevant parameters of the first frequency domain bandwidth; when the occupied time domain resources are of the second time domain resource type (non-SBFD), the transmission parameters are determined based on the relevant parameters of the second frequency domain bandwidth.

The types of transmission parameters include at least one of the following: the size of the frequency hopping offset; the number of bits of first indication information, wherein the first indication information is used to indicate the size of the frequency hopping offset; a frequency domain resource allocation field; the frequency domain starting position of each hop; the frequency domain starting position of the first hop; the frequency domain starting position of the second hop; and an offset value parameter used to determine the resource set corresponding to the uplink channel.

[0201] Configuration method 1: The terminal device receives a first configuration and a second configuration, the first configuration is used to configure a first transmission parameter and / or a first parameter for determining the first transmission parameter, and the second configuration is used for a second transmission parameter and / or a second parameter for determining the second transmission parameter.

[0202] The first transmission parameter is used for uplink transmission in a first time domain resource type, and the second transmission parameter is used for uplink transmission in a second time domain resource type.

[0203] Configuration method two: the terminal device receives a first transmission parameter and a first offset value, and the first transmission parameter and the first offset value are used to determine a second transmission parameter.

[0204] The first transmission parameter is used for uplink transmission in a first time domain resource type, and the second transmission parameter is used for uplink transmission in a second time domain resource type.

[0205] The first transmission parameter and the first offset value may be in the same configuration or in different configurations. Of course, the possibility that the first offset value is agreed upon by a communication protocol is not excluded.

[0206] Configuration method three: The terminal device receives a first parameter and a second offset value, the first parameter is used to determine a first transmission parameter, and the first transmission parameter and the second offset value are used to determine a second transmission parameter.

[0211] The second transmission parameter and the third offset value may be in the same configuration or in different configurations. Of course, the possibility that the third offset value is agreed upon by a communication protocol is not excluded.

[0212] Configuration mode five: The terminal device receives the second parameter and the fourth offset value, the second parameter is used to determine the second transmission parameter, and the second transmission parameter and the fourth offset value are used to determine the first transmission parameter.

[0213] The first transmission parameter is used for uplink transmission in a first time domain resource type, and the second transmission parameter is used for uplink transmission in a second time domain resource type.

[0214] In some embodiments, there are many types of transmission parameters, each of which can use any of the five configuration methods described above, and different transmission parameters can use different configuration methods. Furthermore, the possibility that some transmission parameters are shared between the first time domain resource type and the second time domain resource type is not excluded.

[0215] FIG19 shows a block diagram of an uplink transmission device provided by an exemplary embodiment of the present application. The device can be implemented as part of a terminal device. The device includes:

[0216] A sending module 1920 is configured to send an uplink channel or an uplink signal based on a transmission parameter, where the transmission parameter is determined based on a parameter related to the first frequency domain bandwidth;

[0217] The first frequency domain bandwidth is a subset of the second frequency domain bandwidth. The second frequency domain bandwidth is the available uplink bandwidth configured by the network device for the terminal device, and the first frequency domain bandwidth is the actual available uplink bandwidth determined in the second frequency domain bandwidth based on the configuration of the first duplex mode or the first time domain resource type. Exemplarily, the second frequency domain bandwidth is the uplink BWP of the terminal device. In some embodiments, the first frequency domain bandwidth is a true subset of the second frequency domain bandwidth, that is, the first frequency domain bandwidth belongs to the second frequency domain bandwidth and is smaller than the second frequency domain bandwidth.

[0218] In some embodiments, the uplink BWP is an uplink BWP activated for uplink transmissions by the terminal device. The first frequency-domain bandwidth is the entire bandwidth or a portion of the uplink BWP. Due to differences in available uplink subbands in different duplex modes or different time-domain resource types, the first frequency-domain bandwidth may dynamically change even for the same terminal device.

[0219] In some embodiments, the first frequency domain bandwidth may be understood as an available subband in an uplink BWP, an available uplink subband, an actually available subband, or an actually available uplink subband.

[0220] In some embodiments, the transmission parameters of the uplink transmission include at least one of parameters related to frequency hopping transmission and parameters related to uplink resources.

[0221] The relevant parameters of frequency hopping transmission include at least one of the following: the size of the frequency hopping offset; the number of bits of the first indication information, wherein the first indication information is used to indicate the size of the frequency hopping offset; frequency domain resource allocation; the frequency domain starting position of each hop; the frequency domain starting position of the first hop; and the frequency domain starting position of the second hop.

[0222] In some embodiments, the device further includes: a processing module 1940, configured to determine at least one of the above-mentioned transmission parameters based on relevant parameters of the first frequency domain bandwidth. The determination method may be referred to the relevant sections above and will not be described in detail.

[0223] In some embodiments, the device also includes: a receiving module for receiving at least one of the first indication information, the second indication information, the configuration of the first time domain resource type, the configuration of the second time domain resource type, the configuration of the first frequency domain bandwidth, the configuration of the second frequency domain bandwidth, the configuration of the third frequency domain bandwidth, the configuration of the transmission parameters, and the configuration of the parameters for determining the transmission parameters.

[0224] The sending module 1920 may be implemented by a transmitter, the processing module 1940 may be implemented by a processor or a chip, and the receiving module may be implemented by a receiver.

[0225] To sum up, the device provided in this embodiment determines the transmission parameters by determining the transmission parameters based on the relevant parameters of the first frequency domain bandwidth, and the first frequency domain bandwidth is a subset of the second frequency domain bandwidth. Compared with the method of using the second frequency domain bandwidth to determine the transmission parameters in the related technology, it can adapt to the impact of the new duplex mode on the actual available uplink bandwidth of the terminal device. Even if the actual available uplink bandwidth of the terminal device is smaller than the second frequency domain bandwidth, the transmission parameters can be accurately determined.

[0226] FIG20 shows a flow chart of an uplink transmission device provided by an exemplary embodiment of the present application. The device can be implemented as part of a network device, and the device includes:
