[0049] The frequency hopping method, information indication method, apparatus, terminal, and network-side equipment for uplink transmission provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0050] Please see Figure 2 , Figure 2 This is a flowchart of an uplink frequency hopping method provided in an embodiment of this application. The method is executed by the terminal, such as... Figure 2 As shown, the method includes the following steps:

[0051] Step 21: The terminal obtains the first information.

[0052] Step 22: The terminal determines whether uplink transmission should hop frequencies based on the first information, and / or determines the frequency hopping position information when uplink transmission hops frequencies.

[0053] In this embodiment, the first information may include at least one of the following:

[0054] Indication information from network-side devices;

[0055] Frequency domain resource type configuration information.

[0056] In some embodiments, network-side devices, such as base stations, can dynamically send indication information to terminals to indicate whether uplink transmission should hop frequencies, and / or to indicate information related to the frequency hopping position when uplink transmission hops frequencies.

[0057] In some embodiments, the frequency hopping position-related information mentioned above may include, but is not limited to, at least one of the following: frequency hopping position, reference position of the frequency hopping position, frequency domain offset between two adjacent hops, etc. The frequency hopping position may be indicated based on the starting Physical Resource Block (PRB) index. For example, the number of PRBs in the PUCCH may be predefined, configured by RRC, or determined according to predefined rules. The terminal can determine all PRB positions of the PUCCH transmission based on the starting PRB position and the number of PRBs.

[0058] In some embodiments, the uplink transmission described above involves at least one of the following: Physical Uplink Control Channel (PUCCH), Physical Uplink Shared Channel (PUSCH), Sounding Reference Signal (SRS), etc.

[0059] The frequency hopping method of this application embodiment allows the terminal to determine whether uplink transmission should hop frequencies based on the indication information from the network-side device and / or the frequency domain resource type configuration information, and / or to determine the frequency hopping position information during uplink transmission frequency hopping. Therefore, compared to existing uplink transmission frequency hopping schemes, the flexibility of uplink transmission frequency hopping can be improved. Furthermore, determining the frequency hopping position information during uplink transmission frequency hopping based on the indication information from the network-side device and / or the frequency domain resource type configuration information can avoid or reduce situations where uplink resources are unavailable. Especially in flexible / full-duplex systems, this can significantly reduce the problem of uplink transmission being unable to proceed due to resource unavailability, better adapting to the flexible uplink and downlink configurations in flexible / full-duplex systems and improving system efficiency.

[0060] Optionally, the aforementioned indication information can be carried through Downlink Control Information (DCI). That is, network-side devices can send indication information to the terminal via DCI. Correspondingly, the terminal receives / acquires the indication information sent by the network-side devices via DCI.

[0061] Furthermore, the aforementioned DCI can be any of the following:

[0062] The DCI that schedules the uplink transmission; for example, the base station indicates whether an uplink transmission should hop frequency or not through the indication information in the DCI, in which case the DCI can be the DCI that schedules the uplink transmission; or, the base station indicates the starting PRB index when an uplink transmission hops frequency through the indication information in the DCI, in which case the DCI can be the DCI that schedules the uplink transmission.

[0063] Layer 1 signaling; wherein the transmission time of the Layer 1 signaling is prior to the transmission time of the uplink transmission, and the Layer 1 signaling and the uplink transmission satisfy a predetermined time interval requirement. This predetermined time interval can be set based on actual needs and is not limited thereto.

[0064] In some embodiments, the aforementioned Layer 1 signaling may be selected as a Downlink Grant (DL grant) dedicated DCI, an Uplink Grant (UL grant) dedicated DCI, a Frequency Modulation Indication dedicated DCI, or other types of DCI, without limitation. A DL grant dedicated DCI may be, for example, DCI formats 1_0, 1_1, 1_2, 4_0, 4_1, 4_2, etc. A UL grant dedicated DCI may be, for example, DCI formats 0_0, 0_1, 0_2, etc. A frequency modulation indication dedicated DCI may be, for example, a DCI specifically used to indicate uplink transmission frequency hopping information.

[0065] In some embodiments, when the starting PRB index of the first hop and / or second hop of a PUCCH is indicated by carrying indication information via Layer 1 signaling, this PUCCH can be any / specific type of PUCCH, such as a Hybrid Automatic Repeat Request-ACK (HARQ-ACK) PUCCH, a Scheduling Request (SR) PUCCH, or a Channel State Information (CSI) PUCCH. Alternatively, when the starting PRB index of the first hop and / or second hop of an uplink transmission is indicated by carrying indication information via Layer 1 signaling, this uplink transmission can be any / specific type of uplink transmission, such as a PUCCH, PUSCH, SRS, etc.

[0066] In this embodiment, the network-side device can employ different indication methods for frequency hopping in uplink transmission. The aforementioned indication information can indicate different content, which will be described in detail below.

[0067] Case 1

[0068] In this scenario, the aforementioned indication information includes first indication information, which is used to indicate whether uplink transmission involves frequency hopping. Thus, based on the first indication information, the terminal can determine whether uplink transmission involves frequency hopping, i.e., whether uplink transmission involves frequency hopping or not.

[0069] In some embodiments, the base station can dynamically indicate whether the PUCCH should hop frequencies.

[0070] In other embodiments, the base station can dynamically indicate whether the SRS should hop frequencies.

[0071] Case 2

[0072] In this second scenario, the aforementioned indication information includes second indication information, which is used to indicate the starting PRB index of at least one hop in the uplink transmission. Thus, based on the second indication information, the terminal can determine the starting PRB index of at least one hop in the uplink transmission, and thereby determine the frequency hopping position of the uplink transmission.

[0073] Optionally, the aforementioned second indication information can be used to indicate the starting PRB index of the first and / or second hop of the uplink transmission.

[0074] In some embodiments, the base station can dynamically indicate the starting PRB index of the first hop and / or the second hop of the PUCCH. For example, when the starting PRB index of the first hop of the PUCCH is configured by higher-layer signaling, the starting PRB index of the second hop of the PUCCH is dynamically indicated by the base station. Alternatively, the starting PRB index of the first hop of the PUCCH is dynamically indicated by the base station, while the starting PRB index of the second hop of the PUCCH is configured by higher-layer signaling or determined according to predefined rules. For example, the frequency domain offset between the second hop and the first hop of the PUCCH can be configured by higher-layer signaling, and the terminal determines the starting PRB index of the second hop based on the starting PRB index of the first hop and the frequency domain offset.

[0075] In some embodiments, the base station may dynamically indicate the starting PRB index of the first hop and / or second hop of the PUSCH.

[0076] Optionally, the second indication information described above can be used to indicate the starting PRB index of the m-th hop in the uplink transmission; wherein the m-th hop is at least one of all hops in the uplink transmission; the starting PRB index of the m-th hop is at least one of a plurality of PRB indices configured for the terminal, and m is a positive integer. That is, the m-th hop can be any one of all hops in the uplink transmission, or multiple hops in the uplink transmission, or all hops in the uplink transmission.

[0077] Optionally, the aforementioned second indication information can be used to indicate the starting PRB index combination of at least two hops in the uplink transmission, wherein the starting PRB index combination of at least two hops is one of a plurality of PRB index combinations configured for the terminal. For example, the second indication information can indicate the starting PRB index pair of two hops in the uplink transmission, such as the first hop and the second hop, or it can indicate the starting PRB index combination of two or more hops, such as three or four hops in the uplink transmission.

[0078] In some embodiments, for SRS transmissions, if they have multiple hops, the base station can indicate the starting PRB index combination for the multiple hops via a second indication information.

[0079] In some embodiments, the second indication information described above can be used to indicate the starting PRB index of the first hop in an uplink transmission such as PUCCH / PUSCH / SRS, wherein the starting PRB index of the first hop is one of a plurality of PRB indices configured for the terminal.

[0080] In some embodiments, the aforementioned second indication information may be used to indicate the starting PRB index of the second hop in an uplink transmission such as PUCCH / PUSCH / SRS, wherein the starting PRB index of the second hop is one of a plurality of PRB indices configured for the terminal.

[0081] In some embodiments, for SRS transmissions, if they have four hops, the base station may indicate the starting PRB index for each of the four hops, for example, indicating the following combination (PRB index 1, RB index 2, PRB index 3, PRB index 4), where PRB index 1 to 4 correspond to the starting PRB indices of the first to fourth hops, respectively.

[0082] In some embodiments, the aforementioned second indication information may be used to indicate the starting PRB index pair of the first and second hops of an uplink transmission such as PUCCH / PUSCH / SRS, wherein the starting PRB index pair of the first and second hops is one of a plurality of PRB index pairs configured for the terminal.

[0083] For example, a base station configures N PRB index values ​​through higher-layer signaling such as RRC signaling. The base station then uses DCI to indicate one of the N values ​​as the starting PRB index for the second hop when hopping PUCCH. This DCI can be the DCI that schedules the PUCCH; or it can be L1 signaling that meets a specific time interval requirement before PUCCH transmission, i.e., the time interval is greater than or equal to the specified time interval.

[0084] Case 3

[0085] In this scenario 3, the aforementioned indication information includes third indication information, which is used to indicate the reference position of the starting PRB index of at least one hop in the uplink transmission. For example, this third indication information can be used to indicate the reference position of the starting PRB index of the first and / or second hop in an uplink transmission such as PUCCH / PUSCH / SRS.

[0086] In some embodiments, the base station may dynamically indicate the reference location of the starting PRB index of the first and / or second hop of the PUCCH.

[0087] Optionally, the reference location for the starting PRB index can be any of the following:

[0088] The lowest PRB index of the current BWP and / or carrier; where the current BWP can be understood as the active uplink BWP or active BWP currently corresponding to the terminal, and the different frequency domain resources on the BWP can be at least one of uplink UL, downlink DL, and flexible F.

[0089] The lowest available PRB index for upstream resources;

[0090] The highest PRB index of available uplink resources.

[0091] The available uplink resources can be configured with either uplink UL or flexible F in terms of time-frequency domain resource type. Furthermore, the available uplink resources can be configured with UL / F symbols or time slots, etc.

[0092] In some embodiments, the reference positions of the starting PRB indexes of the first hop and the second hop may both be relative to the lowest PRB index of the current BWP and / or carrier, or both relative to the lowest PRB index of the available uplink resources, or both relative to the highest PRB index of the available uplink resources.

[0093] In other embodiments, the reference position of the starting PRB index of the first hop may be relative to the lowest PRB index of the available uplink resources, and the reference position of the starting PRB index of the second hop may be relative to the highest PRB index of the available uplink resources; or, the reference position of the starting PRB index of the first hop may be relative to the highest PRB index of the available uplink resources, and the reference position of the starting PRB index of the second hop may be relative to the lowest PRB index of the available uplink resources.

[0094] Case 4

[0095] In this scenario 4, the aforementioned indication information includes a fourth indication information, which indicates the frequency domain offset (FH offset) of the a-th hop in the uplink transmission relative to the b-th hop; a and b are positive integers. Thus, given the indication of the starting PRB index of the a-th hop (or b-th hop), the starting PRB index of the b-th hop (or a-th hop) can be obtained. For example, x can be set to 1 and y to 2; or x can be set to 2 and y to 1.

[0096] In some embodiments, the base station may dynamically indicate the frequency domain offset (FHoffset) of the second hop of the PUSCH relative to the first hop.

[0097] It should be noted that, in specific embodiments, the aforementioned indication information may include at least one of the first to fourth indication information, so that the terminal can determine whether uplink transmission should hop frequencies, and / or determine frequency hopping position related information when uplink transmission hops frequencies, based on the received indication information. At least one of the aforementioned first to fourth indication information may be carried by DCI.

[0098] Optionally, in addition to determining whether uplink transmission should hop frequencies based on the first indication information mentioned above, the terminal can also determine whether uplink transmission should hop frequencies based on the configuration information of the network-side equipment. For example, the base station can configure whether uplink transmission should hop frequencies through higher-layer signaling, which may include, but is not limited to, system information and / or RRC information.

[0099] In this embodiment of the application, when the first information includes frequency domain resource type configuration information, step 22 above may include:

[0100] The terminal determines the starting PRB index of the first hop and / or second hop of the uplink transmission based on the frequency domain resource type configuration information;

[0101] And / or,

[0102] The terminal determines the frequency domain offset of the second hop of the uplink transmission relative to the first hop based on the frequency domain resource type configuration information.

[0103] Optionally, the reference location for the starting PRB index of the first hop and / or second hop of the uplink transmission determined above can be any of the following:

[0104] The lowest PRB index of the current BWP and / or carrier; where the current BWP can be understood as the BWP currently corresponding to the terminal, and the different frequency domain resources on the BWP can be at least one of uplink UL, downlink DL, and flexible F;

[0105] The lowest available PRB index for upstream resources;

[0106] The highest PRB index of available uplink resources.

[0107] For example, the terminal determines the starting PRB index of the first and / or second hop of the uplink transmission based on its frequency domain resource type configuration information. `startingPRB_FD` represents the starting PRB index of the first hop, and `secondHopPRB_FD` represents the starting PRB index of the second hop. Then, the reference PRB positions of `startingPRB_FD` and `secondHopPRB_FD` (i.e., the position with index 0, or the starting position of the aforementioned PRB index numbers) can be any of the following:

[0108] 1) Both startingPRB_FD and secondHopPRB_FD are relative to the lowest PRB index of the current BWP and / or carrier. The different frequency domain resources on this BWP can be at least one of uplink UL, downlink DL, or flexible F.

[0109] 2) Both `startingPRB_FD` and `secondHopPRB_FD` are relative to the lowest PRB index of the available UL resource, or both are relative to the highest PRB index of the available UL resource. The time-domain resource configuration of the available UL resource can be a UL / F symbol or a time slot, etc., and the frequency-domain resource type configuration of the available UL resource can be an uplink UL or a flexible F. See, for example... Figure 5 As shown, the time-domain resources of slots 2-7 are configured as UL or F, and some RB sets on slots 2-7 are configured as DL by frequency-domain format signaling. Specifically, the frequency-domain resource type of RB set1 on slots 2-7 is configured as UL, the frequency-domain resource type of RB set2 on slots 4, 6, and 7 is configured as UL, the frequency-domain resource type of RB set0 on slots 3, 4, 6, and 7 is configured as UL, and the remaining RB sets are configured as DL. Therefore, the available UL resources are: in slots 2 and 5, the available UL resources are RB set 1; in slot 3, the available UL resources are RB set 0 and RB set 1; in slots 4 and 6, the available UL resources are RB sets 0-3; and in slot 7, the available UL resources are RB sets 0-3, i.e., the entire BWP.

[0110] 3) `startingPRB_FD` is the lowest PRB index of the available UL resource relative to `secondHopPRB_FD`, and `secondHopPRB_FD` is the highest PRB index of the available UL resource relative to `secondHopPRB_FD`; or, `startingPRB_FD` is the lowest PRB index of the available UL resource relative to `secondHopPRB_FD`, and `secondHopPRB_FD` is the highest PRB index of the available UL resource relative to `secondHopPRB_FD`. The time-domain resource configuration of the available UL resource can be a UL / F symbol or a time slot, and the frequency-domain resource type configuration of the available UL resource can be an uplink UL or a flexible F.

[0111] For example, if the index of the slot / sub-slot where the first hop is located is even, such as 0, 2, 4, ..., then startingPRB_FD is the lowest PRB index relative to the available UL resources, and secondHopPRB_FD is the highest PRB index relative to the available UL resources; or, if the index of the slot / sub-slot where the first hop is located is odd, such as 1, 3, 5, ..., then startingPRB_FD is the highest PRB index relative to the available UL resources, and secondHopPRB_FD is the lowest PRB index relative to the available UL resources.

[0112] For example, if secondHopPRB_FD is a positive integer and is the offset relative to the highest PRB index of the available UL resources, it can represent the offset relative to the highest PRB index of the available UL resources, and its offset direction is the low-frequency direction; or, if secondHopPRB_FD is the offset relative to the highest PRB index of the available UL resources, its value can be negative, representing the offset relative to the highest PRB index of the available UL resources, and its offset direction is the high-frequency direction. In this case, since it is a negative value, it is equivalent to offset to the low-frequency direction.

[0113] In some embodiments, the available UL resources described above may be configured as UL / F by semi-static signaling, with the frequency domain resource type being at least one of UL, flexible F, and unknown. The semi-static signaling may be, for example, at least one of the following: time-domain tdd-UL-DL-ConfigurationCommon, time-domain tdd-UL-DL-ConfigurationDedicated, or time-domain slot format indicator (SFI).

[0114] Optionally, when determining the frequency hopping position information during uplink frequency hopping, the terminal may perform at least one of the following:

[0115] For each uplink transmission, determine the frequency hopping position information during uplink frequency hopping; for example, for each PUCCH, determine the frequency hopping position information.

[0116] For each time unit, determine the frequency hopping position information during uplink transmission frequency hopping; where the time unit can be a slot or a sub-slot, etc.

[0117] For each repetition of an uplink transmission, determine the frequency hopping position information when the uplink transmission hops; for example, for PUCCH or PUSCH repetitions, different repetitions may use different PRB indices, or different repetitions may use the same PRB index, such as determined by the first repetition.

[0118] Optionally, if the frequency domain resources of the nth hop in the uplink transmission are unavailable, the terminal behavior may include at least one of the following:

[0119] 1) The terminal determines that the frequency domain resource has been incorrectly configured or scheduled; for example, for a dynamically indicated frequency domain frequency hopping FH, the terminal does not expect to perform uplink transmission.

[0120] 2) The terminal abandons the transmission of the nth hop; where abandoning (drop) can also be expressed as canceling (cancel) or not transmitting (does not transmit);

[0121] 3) The terminal drops the uplink transmission; wherein, dropping can also mean canceling or not transmitting; it is worth noting that if the uplink transmission is configured or indicates a repetition, the terminal may drop the entire uplink transmission (including all repetitions), or the terminal may determine whether the transmission resources of each repetition are available, and if the transmission resources of a certain repetition are unavailable, the terminal drops the repetition.

[0122] 4) The terminal delays the transmission of the nth hop in time to the next available frequency domain resource;

[0123] 5) The terminal shifts the transmission of the nth hop in the frequency domain to the next available frequency domain resource.

[0125] In some embodiments, if the frequency domain resources of a certain hop in the uplink transmission are unavailable, the terminal may perform the above terminal behavior, provided that the network configuration or dynamic indication of FH is provided.

[0126] Please see Figure 3 , Figure 3 This is a flowchart of an information indication method provided in an embodiment of this application. The method is executed by a network-side device, such as... Figure 3 As shown, the method includes the following steps:

[0127] Step 31: The network-side device sends an instruction message to the terminal.

[0128] The indication information is used by the terminal to determine whether uplink transmission should hop frequencies, and / or to determine the frequency hopping position information when uplink transmission hops frequencies.

[0129] In some embodiments, the frequency hopping position-related information may include, but is not limited to, at least one of the following: frequency hopping position, reference position of the frequency hopping position, frequency domain offset between two adjacent hops, etc. The frequency hopping position may be indicated based on the starting physical resource block (PRB) index.

[0130] In some embodiments, the above-described uplink transmission involves at least one of the following: PUCCH, PUSCH, SRS, etc.

[0131] The information indication method of this application embodiment allows the network-side device to send indication information to the terminal. The terminal then determines, based on this indication information, whether uplink transmission should hop frequencies, and / or determines the frequency hopping position information during uplink frequency hopping. Therefore, compared to existing uplink frequency hopping schemes, this improves the flexibility of uplink frequency hopping. Furthermore, having the terminal determine the frequency hopping position information during uplink frequency hopping based on the indication information from the network-side device avoids situations where uplink resources are unavailable. Especially in flexible / full duplex systems, this significantly reduces the problem of uplink transmission failing due to resource unavailability, better adapting to the flexible uplink and downlink configurations in flexible / full duplex systems and improving system efficiency.

[0132] Optionally, the indication information includes first indication information, which is used to indicate whether the uplink transmission is frequency hopping.

[0133] Optionally, the indication information includes second indication information, which indicates the starting PRB index of at least one hop in the uplink transmission. For example, the second indication information indicates the starting PRB index of the first hop / second hop of the PUCCH / PUSCH.

[0134] Optionally, the second indication information is used to indicate the starting PRB index of the m-th hop of the uplink transmission, wherein the m-th hop is at least one of all hops in the uplink transmission; the starting PRB index of the m-th hop is at least one of a plurality of PRB indices configured for the terminal; and m is a positive integer.

[0135] Optionally, the second indication information is used to indicate the starting PRB index combination of at least two hops of the uplink transmission, wherein the starting PRB index combination of at least two hops is one of a plurality of PRB index combinations configured for the terminal.

[0136] Optionally, the second indication information is used to indicate the starting PRB index of the first hop of the uplink transmission, wherein the starting PRB index of the first hop is one of a plurality of PRB indices configured for the terminal.

[0137] Alternatively, the second indication information is used to indicate the starting PRB index of the second hop of the uplink transmission, wherein the starting PRB index of the second hop is one of a plurality of PRB indices configured for the terminal;

[0138] Alternatively, the second indication information is used to indicate the starting PRB index pair of the first hop and the second hop of the uplink transmission, wherein the starting PRB index pair of the first hop and the second hop is one of a plurality of PRB index pairs configured for the terminal.

[0139] Optionally, the indication information includes third indication information, which is used to indicate the reference position of the starting PRB index of at least one hop of the uplink transmission, such as the first hop and / or the second hop.

[0140] Optionally, the indication information includes fourth indication information, which is used to indicate the frequency domain offset of the a-th hop of the uplink transmission relative to the b-th hop; wherein a and b are positive integers.

[0141] Optionally, the indication information is carried through downlink control information (DCI).

[0142] Furthermore, the DCI is any one of the following:

[0143] DCI that schedules the uplink transmission;

[0144] Layer 1 signaling; wherein the transmission time of the Layer 1 signaling is prior to the transmission time of the uplink transmission, and the Layer 1 signaling and the uplink transmission satisfy a predetermined time interval requirement.

[0145] The following detailed description of this application uses PUCCH transmission as an example of uplink transmission, but it is not limited thereto.

[0146] Example 1:

[0147] In this embodiment 1, the base station dynamically indicates whether frequency hopping is enabled. For example, the frequency hopping type (inter-slot or intra-slot) and the starting PRB indexes of the first and second hops can be configured through higher-layer signaling such as RRC signaling. For example, startingPRB represents the starting PRB index of the first hop, and secondHopPRB represents the starting PRB index of the second hop. The base station then dynamically indicates whether PUCCH frequency hopping is enabled or disabled via DCI. When dynamically indicating whether PUCCH frequency hopping is enabled via DCI, a new indication field in the DCI can be used, an existing indication field in the DCI can be reused (i.e., reinterpreted), or specific values ​​of certain fields in the DCI can be used. Only when the DCI indicates frequency hopping, i.e., enabled, does the terminal enable PUCCH frequency hopping; otherwise, the terminal disables PUCCH frequency hopping, meaning there is no PUCCH frequency hopping. At this point, the PRB where the PUCCH resides can be determined based on the starting PRB or the second Hop PRB. Alternatively, the PRB can be determined based on the PUCCH's time slot / sub-slot and the starting PRB / second Hop PRB. For example, if the index of the PUCCH's time slot / sub-slot is even, the PRB is determined based on the starting PRB; if the index is odd, the PRB is determined based on the second Hop PRB; or vice versa.

[0148] Optionally, the aforementioned DCI can be the DCI that schedules the PUCCH. The aforementioned PUCCH is a dynamically scheduled PUCCH, such as a HARQ-ACK PUCCH that has a corresponding Physical Downlink Control Channel (PDCCH) scheduled, or an instruction for the secondary cell (Scell) to enter sleep mode, or an instruction for the release of a semi-static SPS PDSCH, or a PDCCH that triggers a type 3 or enhanced type 3 codebook. For PUCCHs without a corresponding PDCCH scheduled, such as CSI PUCCH or SR PUCCH, their frequency hopping method is configured according to RRC.

[0149] Alternatively, the aforementioned DCI can be a UL grant or a group public DCI, or a DCI specifically used to indicate PUCCH frequency hopping. In this case, the PUCCH is not necessarily the PUCCH scheduled by this DCI. The PUCCH can be any type of PUCCH received after a specific time interval by the DCI, such as HARQ-ACK PUCCH, CSI PUCCH, and / or SR PUCCH, or a pre-configured / predefined type of PUCCH. The aforementioned specific time interval can be 0, or a value determined based on a predefined method. Optionally, the aforementioned specific time interval is related to the terminal capabilities.

[0150] Optionally, the DCI mentioned above can also indicate the PUCCH frequency hopping type. The PUCCH frequency hopping type can be divided into two types: intra-slot and inter-slot. Intra-slot indicates frequency hopping within a single time unit, while inter-slot indicates frequency hopping between time units.

[0151] Example 2:

[0152] In this embodiment 2, the base station dynamically indicates the frequency hopping position. For example, the base station can configure N index pairs of first-hop PRB index and second-hop PRB index through higher-layer signaling such as RRC signaling. `startingPRB` represents the starting PRB index of the first hop, and `secondHopPRB` represents the starting PRB index of the second hop, as shown in Table 1 below. Although N is 4 in Table 1, this embodiment is not limited to this. Furthermore, the base station can indicate the frequency hopping position when hopping PUCCH through DCI. For example, the DCI can contain ceil(log2(N)) bits of indication information to indicate the frequency hopping position when hopping PUCCH; or, the DCI can contain ceil(log2(1+N)) bits of indication information to indicate the frequency hopping position when hopping PUCCH and whether frequency hopping is performed. For example, based on Table 1, when using the indication information of ceil(log2(1+N)) bits for indication, since ceil(log2(1+N)) = ceil(log2(1+4)) = 2, then: "00" indicates no frequency hopping, "01" indicates the first frequency hopping PRB index pair in base station configuration table 1, "10" indicates the second frequency hopping PRB index pair in base station configuration table 1, and "11" indicates the third frequency hopping PRB index pair in base station configuration table 1. Ceil(X) represents rounding up X.

[0153] Table 1

[0154] FH pair index startingPRB secondHopPRB 0 startingPRB0 secondHopPRB0 1 startingPRB1 secondHopPRB1 2 startingPRB2 secondHopPRB2 3 startingPRB3 secondHopPRB3

[0155] Alternatively, the base station can configure the starting PRB index of the first hop of the PUCCH and the starting PRB index of the second hop of M PUCCHs via higher-layer signaling. Further, the base station indicates the starting PRB index of the second hop of the PUCCH via DCI. For example, the DCI can contain ceil(log2(M)) bits of indication information to indicate the starting PRB index of the second hop of the PUCCH. Of course, ceil(log2(1+M)) bits of indication information can also be used to indicate the starting PRB index of the second hop of the PUCCH and whether frequency hopping is required. Similarly, the base station can also configure the starting PRB index of the second hop of the PUCCH via higher-layer signaling and indicate the starting PRB index of the first hop of the PUCCH via DCI.

[0156] It should be noted that, in addition to configuring / indicating the starting PRB index of the first / second hop of the PUCCH as described above, it is also possible to configure / indicate the starting PRB index of the first hop of the PUCCH, as well as an offset value, PRB offset, which represents the PRB offset of the second hop relative to the first hop. Then, the terminal can determine the starting PRB index of the second hop based on the starting PRB index of the first hop and this offset value.

[0157] Example 3:

[0158] In this embodiment 3, the base station is configured with a semi-static time-domain uplink and downlink timeslot format. For example, the time-domain SFI configures the uplink and downlink transmission directions in the time domain, such as uplink UL, downlink DL, and flexible timeslots or symbols. The DL and / or UL configured in the time-domain semi-static configuration may include DL / UL timeslots / symbols configured by at least one of the following signaling:

[0159] 1) Time-domain tdd-UL-DL-ConfigurationCommon;

[0160] 2) Time-domain tdd-UL-DL-ConfigurationDedicated;

[0161] 3) Semi-static downlink transmissions configured by higher-layer / RRC signaling, such as PDCCH, PDSCH and / or CSI-RS, are located in DL symbols.

[0162] 4) Semi-static uplink transmissions configured by higher-layer / RRC signaling, such as SRS, PUSCH, PUCCH and / or PRACH, are UL symbols.

[0163] 5) The symbol resource where the SSB sent to the terminal is located is a DL symbol, as indicated by ssb-PositionsInBurst in System Information Block SIB1 or ssb-PositionsInBurst in ServingCellConfigCommon.

[0164] 6) The symbol resource containing the control resource set (CORESET) configured by pdcch-ConfigSIB1 in the Master Information Block (MIB) for Type0-PDCCH CSS is a DL symbol.

[0165] In some embodiments, for flexible / full duplex systems, the base station can also configure frequency domain format information, such as FFI (frequency format indicator). Through the frequency domain format information, the base station can configure uplink and downlink directions for different frequency resources at the same time.

[0166] In some embodiments, semi-static signaling such as TDD-UL-DL-ConfigurationCommon and / or TDD-UL-DL-ConfigDedicated can be used to configure time slots or symbols as uplink UL, downlink DL, or flexible F. For example... Figure 4 As shown, slots 0-6 are all configured as DL slots, and slot 7 is configured as a UL slot. Figure 5 As shown, slots 0-2 are all configured as DL slots, slots 2-6 are all configured as flexible slots, and slot 7 is configured as a UL slot.

[0167] In some embodiments, in a flexible / full duplex system, the terminal may also receive other higher-layer signaling or dynamic signaling, such as Frequency Domain Format Indication (FFI), which indicates which RBs / RB sets / RB groups / sub-BWP / sub-band / FRs (for simplicity, the frequency domain resources / granularity below are represented by RB sets) within the BWP are DL / UL / F. In this case, based on these configuration signaling messages that configure uplink and downlink for different frequency resources, as well as TDD-UL-DL-ConfigurationCommon, TDD-UL-DL-ConfigDedicated, and / or SFI, the terminal can determine the uplink and downlink configurations of different RB sets at different times or the uplink and downlink configurations of different RB sets at the same time.

[0168] For example, for Figure 4 As shown in the uplink and downlink configurations, the base station can modify the DL / UL / F slots / symbols configured by TDD-UL-DL-ConfigurationCommon and / or TDD-UL-DL-ConfigDedicated via other signaling. For Figure 5As shown, the base station can configure uplink and downlink for different frequency resources through higher-layer signaling or dynamic signaling. Specifically, in slots 2-6, the base station configures the transmission direction of at least one RB set from RB sets 0-3. For example, for slot 2, RB sets 0, 2, and 3 are designated as DL (Directional Link), and RB set 1 as UL (Ultra-Low ...

[0169] Optionally, the terminal can determine the frequency hopping position of the PUCCH based on the frequency domain resource type configuration of the time unit or symbol in which the PUCCH is located. For example, combining... Figure 5 If the PUCCH is transmitted in slot 2, since only RB set 1 is a UL resource, the terminal can only send uplink transmissions within RB set 1. At this time, there is no downlink reception of UL resources within the same time frame. To ensure PUCCH transmission is possible, the starting PRB index of the PUCCH can be configured relative to the starting position of the available UL resources in the slot / symbol where the PUCCH resides. For example, startingPRB and secondHopPRB are indices relative to the starting PRB of RB set 1. If the available UL resources in the frequency domain differ across multiple symbols containing the PUCCH, the terminal can refer to the frequency domain configuration of the first / last symbol or the starting PRB index of the narrowest frequency bandwidth.
