[0034] To facilitate a clearer understanding of the embodiments of this application, some relevant background technical knowledge is introduced as follows.

[0035] Mobile communication systems need to adapt to more diverse scenarios and service requirements. For example, the main scenarios of 5G include Enhanced Mobile Broadband (eMBB), Ultra-Reliable and Low Latency Communications (URLLC), and Massive Machine Type Communications (mMTC). These scenarios pose requirements such as high reliability, low latency, large bandwidth, and wide coverage on the system. For different application scenarios, the transmission bandwidth required by the terminal is different. In NR, the base station can schedule the terminal to transmit on different bandwidth parts according to the demand.

[0036] In NR, the network configures one or more Bandwidth Parts (BWPs) for the User Equipment (UE) to perform data transmission. A BWP is a continuous segment of resources in the frequency domain, and the base station realizes dynamic bandwidth changes by activating different BWPs for the UE. Figure 2 It is a schematic diagram of the base station provided by the prior art to realize bandwidth change by activating different BWPs for the UE, as Figure 2 shown. At the first moment, the traffic volume of the UE is large, and the base station activates a large bandwidth (BWP1) for the UE; at the second moment, the traffic volume of the UE is small, and the base station activates a small bandwidth (BWP2) for the UE to meet the basic communication requirements; at the third moment, the system discovers that there is a large range of frequency selective fading within the bandwidth where BWP1 is located, or the resources within the frequency range where BWP2 is located are relatively scarce, so it instructs the UE to activate a new bandwidth (BWP3).

[0037] Each BWP can correspond to different configuration parameters. For example, it includes subcarrier spacing, the position and bandwidth of the BWP, Cyclic Prefix (CP), etc.

[0038] The sub-3GHz spectrum has advantages such as low penetration loss and plays an important role in cellular network deployment due to its good coverage. On the one hand, compared with the C-band, the sub-3GHz spectrum is fragmented and allocated to International Mobile Telecommunications (IMT), and due to competition among mobile operators, the bandwidth of each spectrum block is relatively narrow. On the other hand, almost all operators globally have multiple sub-3GHz bands (such as 700MHz, 800MHz, 900MHz, 1.4GHz, 1.8GHz, 2.1GHz, 2.3GHz, or 2.6GHz bands). If these discontinuous spectrums can be effectively aggregated to form a "single" carrier with a relatively large bandwidth, all operators can benefit.

[0039] I. PUCCH Resource Configuration

[0040] In NR R15, when performing uplink carrier aggregation (CA), up to two physical uplink control channel (PUCCH) groups (primary PUCCH group and secondary PUCCH group) can be configured, and the PUCCH configuration and transmission within each PUCCH group are carried out separately. Within a PUCCH group, the PUCCH resources can only be configured and transmitted on the primary cell (Pcell) or the PUCCH switched secondary cell (PUCCH-sSCell). In Rel-15, the base station can configure UE-specific PUCCH resources for each UE through radio resource control (RRC) signaling, where the UE-specific PUCCH resources are configured on each bandwidth part (BWP) through the information element (IE) PUCCH-Config. That is, each PUCCH resource is within one BWP.

[0041] II. NR Uplink Transmission with Frequency Hopping

[0042] In the NR system, uplink transmission supports frequency hopping transmission. Briefly speaking, frequency hopping means that the uplink resource blocks within each orthogonal frequency division multiplexing (OFDM) symbol can hop on different subcarriers to avoid interference and obtain frequency diversity gain to improve system capacity or coverage.

[0043] The frequency hopping of PUCCH, Physical Uplink Shared Channel (PUSCH), and Sounding Reference Signal (SRS) is divided into two types: intra-slot (within a time unit) and inter-slot (between time units). Among them, intra-slot represents frequency hopping within a time unit, and inter-slot represents frequency hopping between time units. Therefore, inter-slot frequency hopping is only applicable to PUCCH, PUSCH, or SRS that support repeated transmission, such as PUCCH format 1, 3, and 4.

[0044] III. Frequency Hopping Mode Configuration of PUCCH

[0045] For the common PUCCH (including PUCCH format 0 / 1), it can only be configured through the PUCCH identifier (ID) in the initial UL BWP of System Information Block 1 (SIB1) on the Pcell, and the PUCCH resource parameter configuration is obtained by looking up the table. At the same time, on this initial UL BWP, if interlace transmission is not configured, the common PUCCH defaults to the intra-slot frequency hopping mode.

[0046] For the dedicated PUCCH (including PUCCH format 0 / 1 / 2 / 3 / 4), it can be configured on any UL BWP of the Pcell or PUCCH-sSCell. For non-repeated PUCCH transmission, the intra-slot frequency hopping mode can be configured through the PUSCH of RRC.

[0047] For the dedicated PUCCH (including PUCCH format 1 / 3 / 4), it can be configured for repeated transmission in N time slots (slots). In this case, the intra-slot frequency hopping mode or the inter-slot frequency hopping mode can be configured through RRC.

[0048] In Rel-16, the sub-slot-based dedicated PUCCH (including PUCCH format 0 / 1 / 2 / 3 / 4) was introduced. It does not support repeated PUCCH transmission, and the intra-slot frequency hopping mode can be configured through the PUCCH of RRC.

[0049] In Rel-17, the repeated transmission of dedicated PUCCH (including PUCCH format 0 / 1 / 2 / 3 / 4) based on sub-slots is introduced, and the intra-slot hopping mode or inter-slot hopping mode can be configured through the PUCCH configuration of RRC.

[0050] In Rel-17, for the repeated transmission of PUCCH, the number of repeated transmissions of each PUCCH can also be determined through the PUCCH configuration of RRC and the indication of DCI.

[0051] For common PUCCH, the Physical Resource Block (PRB) index of the first hop is determined by the parameter configured in the system information, that is, The second one is For dedicated PUCCH, the PRB indexes of the first hop and the second hop are both configured by RRC, that is, configured through the parameters startingPRB and secondHopPRB respectively. Whether it is common PUCCH or dedicated PUCCH, the PRB index of each hop is relative to the first PRB of the UL BWP.

[0052] IV. Hopping Mode Configuration of PUSCH

[0053] The hopping of PUSCH is only applied when the resource allocation type 1 (allocating continuous PRBs to a PUSCH transmission in the way of using the Resource Indicator Value (RIV)) is used.

[0054] For the PUSCH scheduled by the Downlink Control Information (DCI) 0_0 scrambled by the Random Access Response (RAR) UL grant or Temporary Cell-Radio Network Temporary Identity (TC-RNTI), the BWP size is the size of the initial UL BWP, there is no repeated transmission currently, the intra-slot hopping mode is enabled by default, and whether the scheduled PUSCH performs intra-slot hopping transmission is controlled through the frequency hopping field.

[0055] For the PUSCH of Message A (Msg A), there is no repeated transmission currently. Whether to perform intra-slot frequency hopping transmission can be determined by msgA-intraSlotFrequencyHopping.

[0056] For the PUSCH scheduled by DCI 0_0 / 0_1 / 0_2 or the Type 2 Configured Grant (CG) PUSCH activated by DCI 0_0 / 0_1 / 0_2 (where cg-nrofSlots and cg-nrofPUSCH-InSlot are not configured) with the indication of Repetition Type A, the intra-slot frequency hopping mode can be enabled through the PUSCH configuration in RRC when repetition is not configured; when repetition is configured, the intra-slot or inter-slot frequency hopping mode can be enabled through the PUSCH configuration in RRC. Finally, whether the scheduled PUSCH performs the enabled frequency hopping mode transmission is controlled by the frequency hopping field in DCI.

[0057] For the Type 1 CG PUSCH with the indication of Repetition Type A (where cg-nrofSlots and cg-nrofPUSCH-InSlot are not configured), the intra-slot frequency hopping mode can be enabled through the PUSCH configuration in RRC when repetition is not configured; when repetition is configured, the intra-slot or inter-slot frequency hopping mode can be enabled through the PUSCH configuration in RRC. Finally, whether the Type 1 CG PUSCH performs the enabled frequency hopping mode transmission is controlled by whether the frequency hopping offset field is configured in RRC.

[0058] For the PUSCH scheduled by DCI 0_0 / 0_1 / 0_2 or the Type 2 CG PUSCH activated by DCI 0_0 / 0_1 / 0_2 (where cg-nrofSlots and cg-nrofPUSCH-InSlot are not configured) with the indication of Repetition Type B, the inter-repetition or inter-slot frequency hopping mode can be enabled through the PUSCH configuration in RRC, and finally, whether the scheduled PUSCH performs the enabled frequency hopping mode transmission is controlled by the frequency hopping field in DCI.

[0059] For a Type 1 CG PUSCH indicated as Repetition Type B (cg-nrofSlots and cg-nrofPUSCH-InSlot not configured), the Inter-repetition or Inter-slot frequency hopping mode can be enabled through the PUSCH configuration in RRC. Whether to perform the enabled frequency hopping mode transmission for the Type 1 CG PUSCH is controlled by whether the frequency hopping offset field is configured in RRC.

[0060] V. SRS Frequency Hopping Mode Configuration

[0061] Whether the SRS resource hops is determined by the parameters b hop and B SRS in the higher layer configuration. For example, when b hop ≥ B SRS , the SRS frequency hopping is turned off; otherwise, the frequency hopping is enabled. Depending on the parameter values of different Frequency hopping configurations, frequency hopping between different symbols within a time slot (intra-slot) or between different time slots (inter-slot) can be supported.

[0062] In the prior art, the carrier of each cell is a continuous frequency domain resource, and the transmission resource is restricted within a BWP on a cell. The maximum bandwidth of each BWP can be 100 MHz. For fragmented spectrum, such as a large amount of fragmented spectrum in the Sub-3GHz spectrum, according to the prior art, if fragmented spectrum is to be used, carrier aggregation (CA) is the traditional solution for operators and terminals to aggregate the spectrum, that is, different continuous spectrums are used as separate carriers respectively. However, the existing CA mechanism treats each carrier as an independent serving cell and assumes that each carrier is independently deployed. The independent management of each carrier will bring unnecessary overhead and efficiency loss (such as independent control signaling, common signaling, etc.), which also brings unnecessary processes and delays (such as synchronization, SCell addition / release / activation / measurement / mobility, etc.). In addition, the CA mechanism is only beneficial to UEs in the connected mode RRC_connected, that is, UEs that have completed the RRC connection with the network, and is not beneficial to UEs in the idle mode / non-active mode RRC_idle / inactive (e.g., initial access / small data transmission (SDT)).

[0063] Therefore, introducing flexible cells can flexibly and efficiently utilize adjacent discontinuous spectrums from the perspectives of L1 / L2 / L3 signaling, procedures, and cell management. It benefits UEs in both the CONNECTED state and the IDLE state, thereby improving the perceived data rate, energy saving, system capacity, and coverage for users. It also simplifies network management complexity and improves energy efficiency. In addition, these narrow-bandwidth carriers cannot provide or provide limited frequency diversity gain.

[0064] The following will, in conjunction with the accompanying drawings, detail the frequency hopping transmission method provided by the embodiments of the present application through some embodiments and their application scenarios.

[0065] The frequency hopping transmission method provided by the embodiments of the present application can be applied to scenarios of frequency hopping transmission between frequency domain units in uplink transmission or downlink transmission. The terminal determines, based on target information or predefined rules, the frequency domain unit where at least one hop of the first transmission is located among at least two hops; the target information is used to indicate the frequency domain unit where at least one hop of the at least two hops is located; the predefined rules are used to determine the frequency domain unit where at least one hop of the at least two hops is located; the first transmission supports frequency hopping transmission on different frequency domain units; the terminal transmits on the frequency domain unit where at least one hop of the at least two hops is located, realizing frequency hopping transmission of the first transmission between different frequency domain units, and thus being able to obtain a relatively large frequency diversity gain or increase the anti-interference ability of uplink transmission, improving the performance of the communication system.

[0066] Figure 3 is a schematic flowchart of the frequency hopping transmission method provided by the embodiments of the present application, as Figure 3 shown, this method includes step 301 - step 302; where:

[0067] Step 301, the terminal determines, based on target information or predefined rules, the frequency domain unit where each hop of the first transmission is located among at least two hops; the target information is used to indicate the frequency domain unit where at least one hop of the at least two hops is located; the predefined rules are used to determine the frequency domain unit where at least one hop of the at least two hops is located; the first transmission supports frequency hopping transmission on different frequency domain units.

[0068] It should be noted that the embodiments of the present application can be applied to scenarios of frequency hopping transmission between frequency domain units in uplink transmission or downlink transmission. The terminal includes, but is not limited to, the types of terminal 11 listed above, and the network-side device includes, but is not limited to, the types of network-side device 12 listed above. The embodiments of the present application are not limited thereto.

[0069] Specifically, a cell consists of at least one frequency-domain unit, and the frequency-domain units may be discontinuous. A frequency-domain unit is a set of continuous frequency-domain resources. The frequency-domain unit can be a bandwidth (band), a carrier, a subband, a BWP, etc., and the size of each frequency-domain unit can be different. For example, a cell consists of four frequency-domain units with sizes of 3 MHz, 10 MHz, 5 MHz, and 5 MHz respectively. The first transmission can be an uplink transmission or a downlink transmission. The first transmission supports frequency hopping transmission on different frequency-domain units. For example, the terminal receives the first information sent by the network-side device, and the first information is used for the network-side device to configure or indicate that the first transmission supports frequency hopping transmission on different frequency-domain units. When frequency hopping is enabled, for example, the network-side device enables frequency hopping transmission through high-layer signaling or dynamic signaling, different hops of the first transmission can be within different frequency-domain units. The frequency-domain unit can be identified by a frequency-domain unit index (index / ID). If the frequency-domain unit corresponds to a band, the frequency-domain unit can also be identified by the band number. For simplicity, in this application, it is identified by the frequency-domain unit index. The method in this application can also be applicable to the case where the frequency-domain unit is identified by the band number.

[0070] Optionally, the terminal receives high-layer signaling or dynamic signaling sent by the network-side device. The high-layer signaling is used to configure the target information, and the dynamic signaling is used to indicate the target information.

[0071] The network-side device can send high-layer signaling or dynamic signaling to the terminal, and the terminal receives the high-layer signaling or dynamic signaling sent by the network-side device. Among them, the high-layer signaling is used to configure the target information, and the dynamic signaling is used to indicate the target information. The target information is used to indicate the frequency-domain unit where at least one hop of at least two hops is located.

[0072] The terminal can also obtain predefined rules through protocol predefinition. Among them, the terminal can determine the frequency-domain unit where at least one hop of at least two hops is located based on the predefined rules.

[0073] Therefore, the terminal can determine the frequency-domain unit where one hop of at least two hops of the first transmission is located according to the target information or the predefined rules.

[0074] For example, according to the predefined rules, determine the frequency-domain unit where the first hop is located, and the frequency-domain unit where each hop starting from the second hop is located is determined by the network-side device through high-layer signaling configuration or dynamic signaling indication. Or, according to the predefined rules, determine the frequency-domain unit where each hop starting from the second hop is located, and the frequency-domain unit where the first hop is located is determined by the network-side device through high-layer signaling configuration or dynamic signaling indication.

[0075] Optionally, for each of at least two hops predefined by the protocol, the frequency domain unit where the hop is located. For example, the first transmission includes 2 hops. The frequency domain unit where the first hop is located is the frequency domain unit with the smallest frequency domain unit index, the smallest frequency, or the frequency domain unit indicated to transmit the first transmission among the active frequency domain units. The frequency domain unit where the second hop is located is the frequency domain unit with the largest frequency domain unit index or the highest frequency among the active frequency domain units, or the next frequency domain unit or the next available or active frequency domain unit of the frequency domain unit where the first hop is located.

[0076] Optionally, the target information includes at least one of the following:

[0077] (1) First information, used to indicate the frequency domain unit where each of the at least two hops is located.

[0078] Specifically, the network configuration indicates the first information. For example, the first transmission includes 2 hops, and the base station configures or indicates the frequency domain unit index where the first hop is located The base station configures or indicates the frequency domain unit index where the second hop is located

[0079] Optionally, when the frequency hopping of the first transmission is enabled and the base station configures or indicates the frequency domain unit index where the first hop is located, the base station configures, indicates, or the protocol predefines the frequency domain unit index where the second hop is located

[0080] (2) Second information, used to indicate the frequency domain unit index where the first hop is located. Specifically, the frequency domain unit index where the first hop is located can be determined based on predefined rules, network configuration, or network indication.

[0081] (3) First frequency domain unit offset; the first frequency domain unit offset is used to indicate the offset of the frequency domain unit index where each hop starting from the second hop is located relative to the frequency domain unit index where the first hop is located, or relative to the frequency domain unit index where the previous hop is located, or the minimum offset.

[0082] Optionally, the first frequency domain unit offset offset only considers the active frequency domain units, that is, it offsets offset frequency domain units backward in the active frequency domain units according to the frequency domain unit where the first hop is located.

[0083] For example, the base station configures or indicates the frequency domain unit index where the first hop is located and configures or indicates that the offset of the frequency domain unit index where the second hop is located relative to the frequency domain unit index where the first hop is located is 2. The terminal determines the frequency domain unit index where the second hop is located according to the frequency domain unit index where the first hop is located and the offset 2 as

[0084] For example, the base station configures or indicates the frequency domain unit index where the first hop is located and configures or indicates that the offset of the frequency domain unit index where the second hop is located relative to the frequency domain unit index where the first hop is located is 2. The indexes of the frequency domain units in which the terminal is activated are 0, 1, 4, 5, and 6 respectively. The terminal determines the frequency domain unit index where the second hop is located as 5 in the activated frequency domain units according to the frequency domain unit index where the first hop is located and the offset 2

[0085] For example, the base station configures or indicates the frequency domain unit index where the second hop is located and configures or indicates that the offset of the frequency domain unit index where the third hop is located relative to the frequency domain unit index where the previous hop is located is 2. The terminal determines the frequency domain unit index where the third hop is located as according to the frequency domain unit index where the second hop is located

[0086] For example, the base station configures or indicates the frequency domain unit index where the first hop is located The base station configures or indicates that the offset of the frequency domain unit index where each hop starting from the second hop is located relative to the frequency domain unit index where the previous hop is located is 2. The terminal first determines the frequency domain unit index as according to the frequency domain unit index where the first hop is located (the offset times is 1). If the frequency domain unit with the frequency domain unit index 3 is available, the frequency domain unit index where the second hop is located is 3; if the frequency domain unit with the frequency domain unit index 3 is not available, the terminal offsets by 2 on the basis of the frequency domain unit index 3 to determine the frequency domain unit index as (the offset times is 2). If the frequency domain unit with the frequency domain unit index 5 is available, it is determined that the frequency domain unit with the frequency domain unit index 5 is the frequency domain unit index where the second hop is located. Otherwise, continue to offset by 2 on the basis of the frequency domain unit index 5 until an available frequency domain unit is found or the offset times reaches the maximum number of times. At this time, if the frequency domain unit with the frequency domain unit index 5 is available, the offset between the frequency domain unit index where the second hop is located, which is 5, and the frequency domain unit index where the first hop is located, which is 1, is 4

[0087] (4) The first frequency domain unit offset list; the first frequency domain unit offset list includes at least one second frequency domain unit offset, and the second frequency domain unit offset is used to indicate the offset of the frequency domain unit index where each hop starting from the second hop is located relative to the frequency domain unit index where the first hop is located, or the offset relative to the frequency domain unit index where the previous hop is located, or the minimum offset

[0088] Specifically, the first frequency-domain unit offset list may include at least one second frequency-domain unit offset. For example, if the first transmission includes two hops, only one second frequency-domain unit offset is required to determine the frequency-domain unit index where the second hop is located. The first frequency-domain unit offset list contains one second frequency-domain unit offset, and the terminal determines the frequency-domain unit where the second hop is located based on the frequency-domain unit index where the first hop is located and the second frequency-domain unit offset. Or if the first transmission includes two hops and the first frequency-domain unit offset list contains multiple second frequency-domain unit offsets, the terminal determines the candidate frequency-domain units where the second hop is located based on the frequency-domain unit index where the first hop is located and the second frequency-domain unit offsets. For example, the terminal determines the first candidate frequency-domain unit based on the frequency-domain unit where the first hop is located and the first second frequency-domain unit offset in the first frequency-domain unit offset list. If this frequency-domain unit is available, it is determined that this candidate frequency-domain unit is the frequency-domain unit where the second hop is located. If this candidate frequency-domain unit is unavailable, the terminal determines the second candidate frequency-domain unit based on the frequency-domain unit where the first hop is located and the second second frequency-domain unit offset in the frequency-domain unit offset list, and determines the frequency-domain unit where the second hop is located according to whether the second candidate frequency-domain unit is available. If the second candidate frequency-domain unit is unavailable, the terminal determines the third candidate frequency-domain unit based on the frequency-domain unit where the first hop is located and the third second frequency-domain unit offset in the first frequency-domain unit offset list, and so on, until an available frequency-domain unit is determined or until the last second frequency-domain unit offset in the first frequency-domain unit offset list is reached.

[0089] Optionally, assuming that PUCCH / PUSCH has only two hops, a first frequency-domain offset unit list configured by the base station contains multiple second frequency-domain unit offsets, and each second frequency-domain unit offset is used to indicate the offset of the frequency-domain unit index where each hop starting from the second hop is located relative to the frequency-domain unit index where the first hop is located. At this time, the multiple second frequency-domain unit offsets configured in this first frequency-domain offset unit list are candidate offsets, or in other words, the frequency-domain units determined according to the multiple second frequency-domain unit offsets are candidate frequency-domain units. The terminal can use only one of the frequency-domain units to transmit the second hop. For example, the terminal uses the first available candidate frequency-domain unit as the frequency-domain unit where the second hop is located.

[0090] Optionally, each second frequency-domain unit offset in the first frequency-domain unit offset list corresponds one-to-one to each hop starting from the second hop. For example, the first second frequency-domain unit offset in the first frequency-domain unit offset list corresponds to the second hop, and the second second frequency-domain unit offset in the first frequency-domain unit offset list corresponds to the third hop.

[0091] Optionally, the indication of the frequency-domain unit where the first hop is located and the indication of the first frequency-domain unit offset list can be separated and independently indicated, and the indication methods can be the same or different. For example, the base station can configure one or more first frequency-domain unit offset lists and indicate one of the first frequency-domain unit offset lists for the first transmission, and the first frequency-domain offset unit list is the first frequency-domain unit offset list indicated by the fourth information.

[0092] (5) At least one pair of frequency-domain units; the pair of frequency-domain units is used to indicate the frequency-domain units associated with the frequency-domain unit where the first hop is located.

[0093] Specifically, the base station configures one or more pairs of frequency-domain units, and each pair of frequency-domain units is used to indicate the frequency-domain units associated with the frequency-domain unit where the first hop is located.

[0094] For example, the first transmission includes 2 hops. The base station configures or indicates 1 pair of frequency-domain units for the first transmission, where the pair of frequency-domain units is used to indicate the frequency-domain unit where the second hop is located, which is associated with the frequency-domain unit where the first hop is located; the terminal can determine the frequency-domain unit where the second hop is located based on the frequency-domain unit where the first hop is located and the pair of frequency-domain units.

[0095] For example, the base station configures or indicates 3 pairs of frequency-domain units for the first transmission, where pair of frequency-domain units 1 indicates the frequency-domain unit where the second hop is located, which is associated with the frequency-domain unit where the first hop is located; pair of frequency-domain units 2 indicates the frequency-domain unit where the third hop is located, which is associated with the frequency-domain unit where the first hop is located; pair of frequency-domain units 3 indicates the frequency-domain unit where the fourth hop is located, which is associated with the frequency-domain unit where the first hop is located. The terminal can determine the frequency-domain unit where the second hop is located, the frequency-domain unit where the third hop is located, and the frequency-domain unit where the fourth hop is located respectively based on the frequency-domain unit where the first hop is located and the 3 pairs of frequency-domain units.

[0096] (6) The first frequency-domain unit list; the first frequency-domain unit list is used to indicate the frequency-domain unit indexes where each hop starts from the second hop.

[0097] Specifically, the base station configures or indicates the frequency-domain unit index where the first hop is located The base station also configures or indicates a first frequency-domain unit list for the first transmission; the first frequency-domain unit list includes multiple frequency-domain unit indexes, and each frequency-domain unit index in the first frequency-domain unit list corresponds to the frequency-domain unit index where each hop starts from the second hop. For example, the first frequency-domain unit list includes 3 frequency-domain unit indexes, where the 1st frequency-domain unit index corresponds to the frequency-domain unit index where the second hop is located, the 2nd frequency-domain unit index corresponds to the frequency-domain unit index where the third hop is located, and the 3rd frequency-domain unit index corresponds to the frequency-domain unit index where the fourth hop is located.

[0098] Optionally, assume that there are only 2 hops for PUCCH / PUSCH. The multiple frequency domain unit indices configured in the first frequency domain unit list are candidate frequency domain unit indices, and the terminal can select one of them to transmit the second hop. For example, the terminal uses the first available frequency domain unit as the frequency domain unit where the second hop is located.

[0099] (7) Second frequency domain unit list; the second frequency domain unit list is used to indicate the frequency domain unit index where each hop of the at least two hops is located.

[0100] Specifically, the base station configures or indicates a second frequency domain unit list for the first transmission. The second frequency domain unit list includes multiple frequency domain unit indices, and each frequency domain unit index in the second frequency domain unit list respectively corresponds to the frequency domain unit index where each hop is located. For example, the second frequency domain unit list includes 4 frequency domain unit indices. Among them, the 1st frequency domain unit index corresponds to the frequency domain unit index where the first hop is located, the 2nd frequency domain unit index corresponds to the frequency domain unit index where the second hop is located, the 3rd frequency domain unit index corresponds to the frequency domain unit index where the third hop is located, and the 4th frequency domain unit index corresponds to the frequency domain unit index where the fourth hop is located. The terminal can determine the frequency domain unit where each hop is located according to the second frequency domain unit list.

[0101] Optionally, assume that there are only 2 hops for PUCCH / PUSCH. The multiple frequency domain unit indices configured in the second frequency domain unit list are candidate frequency domain unit indices, and the terminal can select two of them to transmit the second hop. For example, the terminal uses the first available frequency domain unit among the candidate frequency domain units as the frequency domain unit where the first hop is located, and uses the second available frequency domain unit among the candidate frequency domain units as the frequency domain unit where the second hop is located.

[0102] (8) Frequency hopping pattern, used to indicate the frequency domain unit where each hop of the at least two hops is located.

[0103] Specifically, the frequency hopping pattern pattern indicates the frequency domain unit where each hop of the first transmission is located, and the terminal can determine the frequency domain unit where each hop is located according to the frequency hopping pattern.

[0104] Optionally, the hopping pattern further indicates the time domain unit where each hop of the first transmission is located or the relationship between the time domain units where different hops are located. For example, it is indicated by an X-bit bitmap, where each bit of the bitmap corresponds to a time unit, 1 indicates that the first transmission is made in this time unit, and 0 indicates that the first transmission is not made in this time unit. For example, 10010 means that the first transmission makes the first hop and the second hop in the first slot and the fourth slot respectively. The first slot and the fourth slot may be the first slot or the fourth slot starting from a certain slot configured or indicated by the base station. In the prior art, the time domain unit where the first hop of the first transmission is located is determined according to the base station configuration or indication, and the time domain units where the remaining hops are located are determined according to predefined rules (for example, the time domain units where different hops are located are consecutive time slots or sub-time slots or consecutive available time slots or sub-time slots, etc.). The hopping pattern further indicating the time domain unit where each hop of the first transmission is located or the relationship between the time domain units where different hops are located can flexibly indicate the time domain units where different hops are located, ensure that each hop of the first transmission can be transmitted, and improve the reliability of the first transmission.

[0105] Step 302: The terminal performs transmission on the frequency domain unit where at least one hop of the at least two hops is located.

[0106] Specifically, after the terminal determines the frequency domain unit where each hop of at least two hops of the first transmission is located based on the target information or predefined rules, when the frequency hopping transmission of the first transmission is enabled, the terminal can perform transmission on the frequency domain unit where at least one hop of the at least two hops is located. Among them, the frequency hopping may be inter-slot hopping, intra-slot hopping, or inter-transmission occasion (such as inter-PUCCH, inter-PUSCH) hopping.

[0107] Preferably, the frequency domain hopping is inter-slot hopping. For example, different hops of the first transmission are made in different time slots. Or rather, within the same time slot, the first transmission is made on the same frequency domain unit.

[0108] It should be noted that when the frequency domain unit where any hop is located is unavailable (for example, the frequency domain unit is deactivated or in an inactive state, or the frequency domain bandwidth of the first transmission exceeds the frequency domain range of the frequency domain unit, or the transmission direction of the first transmission does not match the transmission direction configured or indicated for the frequency domain unit. For example, when the first transmission is an uplink transmission and the frequency domain unit corresponding to any symbol position is configured or indicated as a downlink (DL) symbol), the terminal may not perform transmission on this frequency domain unit. For example, if the first transmission includes two hops, the frequency domain unit where the first hop is located is available, and the frequency domain unit where the second hop is located is unavailable, then the terminal cancels the first transmission, or the terminal cancels the transmission of the second hop, or the terminal cancels the frequency domain hopping transmission, transmits the first hop and the second hop on the frequency domain unit where the first hop is located, and does not perform transmission on the above-mentioned frequency domain unit where the second hop is located, or the terminal switches the second hop to another available frequency domain unit for transmission according to predefined rules and / or base station instructions or delays it to another available time unit for transmission.

[0109] Optionally, the availability of the frequency domain unit includes at least one of the following: the frequency domain unit is activated or in an active state; the transmission direction configured or indicated for the time domain position corresponding to the frequency domain unit is the same as that of the first transmission; for example, when the first transmission is an uplink transmission, the time domain position corresponding to the frequency domain unit is configured or indicated as UL, flexible, or SubBand Full Duplex (SBFD) symbol; when the first transmission is a downlink transmission, the time domain position corresponding to the frequency domain unit is configured or indicated as DL, flexible, or SBFD symbol; the frequency domain resources of the first transmission are within the available resource range of the frequency domain unit.

[0110] Optionally, the hopping mode of the first transmission is intra-slot hopping, inter-slot hopping, or inter-transmission occasion hopping (such as inter-PUCCH, inter-PUSCH).

[0111] In the embodiments of the present application, the terminal determines the frequency domain unit where each of at least two hops of the first transmission is located based on target information or predefined rules; the target information is used to indicate the frequency domain unit where at least one of the at least two hops is located; the predefined rules are used to determine the frequency domain unit where at least one of the at least two hops is located; the first transmission supports hopping transmission on different frequency domain units; enabling the terminal to perform transmission on the frequency domain unit where at least one of the at least two hops is located, realizing the hopping transmission of the first transmission between different frequency domain units, and thus being able to obtain a larger frequency diversity gain and improve the performance of the communication system.

[0112] Optionally, the method for obtaining the frequency domain unit index where the first hop is located is the same as or different from the method for obtaining the frequency domain unit index where each hop starting from the second hop is located.

[0113] Specifically, the base station configures the frequency domain unit index where the first hop is located through high-layer signaling, and indicates the frequency domain unit index where the second hop is located through dynamic indication signaling; or, the base station indicates the frequency domain unit index where the first hop is located through dynamic indication signaling, and configures the frequency domain unit index where the first hop is located through high-layer signaling.

[0114] In the embodiments of the present application, the terminal can accurately determine the frequency domain unit where each of at least two hops of the first transmission is located based on the target information configured or indicated by the base station, so that the terminal can perform transmission on different frequency domain units where at least one of the at least two hops is located, thereby obtaining a larger frequency diversity gain or increasing the anti-interference ability of the uplink transmission, and improving the performance of the communication system.

[0115] Optionally, the terminal determines the frequency domain unit index where the h-th hop is located based on the frequency domain unit index where the first hop is located and the first frequency domain offset; where h is an integer greater than 1; or, the terminal determines the frequency domain unit index where the (m + 1)-th hop is located based on the frequency domain unit index where the m-th hop is located and the first frequency domain offset; where m is an integer greater than 0.

[0116] Specifically, when the target information includes the second information and the first frequency domain offset, the terminal can determine the frequency domain unit index where the h-th hop is located based on the frequency domain unit index where the first hop is located indicated by the second information and the first frequency domain offset, where h is an integer greater than 1. For example, when h = 2, the frequency domain unit index where the first hop is located is 1, and the first frequency domain offset is 2, then the terminal can determine that the frequency domain unit index where the second hop is located is 3; when h = 3, the terminal can determine that the frequency domain unit index where the third hop is located is 5.

[0117] Alternatively, the terminal can determine the frequency domain unit index where the (m + 1)-th hop is located based on the frequency domain unit index where the m-th hop is located and the first frequency domain offset; where m is an integer greater than 0. For example, when m = 1, the frequency domain unit index where the m-th hop is located is 1, and the first frequency domain offset is 2, the determined frequency domain unit index is 3, but since the frequency domain unit with index 3 is unavailable, the terminal offsets by 2 based on the frequency domain unit index 3 and determines that the frequency domain unit index is 5, and the frequency domain unit with index 5 is available, then the frequency domain unit index where the second hop is located is 5.

[0118] In an embodiment of the present application, the terminal determines the frequency domain unit index where the h-th hop is located through the frequency domain unit index where the first hop is located and the first frequency domain unit offset; where h is an integer greater than 1; alternatively, the terminal determines the frequency domain unit index where the (m + 1)-th hop is located based on the frequency domain unit index where the m-th hop is located and the first frequency domain unit offset; where m is an integer greater than 0, realizing frequency hopping transmission between different frequency domain units, so that sufficient frequency domain diversity gain can be obtained or the anti-interference ability can be increased, improving the effectiveness and performance of the communication system.

[0119] Optionally, the terminal determines the frequency domain unit index where the (m + 1)-th hop is located based on the frequency domain unit index where the m-th hop is located and the first frequency domain unit offset, including:

[0120] The terminal determines the frequency domain unit index N where the m-th hop is located m and the first frequency domain unit offset offset1, and determines that the frequency domain unit index where the (m + 1)-th hop is located is (N m + offset1 * n); where n satisfies at least one of the following: n is the smallest positive integer available for the frequency domain unit with the frequency domain unit index (N m + offset1 * n); n is less than or equal to the first value; n is a predefined integer.

[0121] For example, when m is 1, the frequency domain unit index N where the m-th hop is located m is 1, and the first frequency domain unit offset offset1 is 2, then the frequency domain unit index determined by the first offset of the terminal is 1 + 2 * 1 = 3. However, since the frequency domain unit with the index 3 is unavailable, the terminal offsets by 2 based on the frequency domain unit index 3, then the frequency domain unit index determined by the second offset is 1 + 2 * 2 = 3. In the case where the frequency domain unit with the index 5 is unavailable, the terminal offsets by 2 based on the frequency domain unit index 5, then the frequency domain unit index determined by the third offset is 1 + 2 * 3 = 3. In the case where the frequency domain unit with the index 7 is unavailable, the offset is repeated until an available frequency domain unit is found or until the maximum number of offsets predefined or configured by the base station is completed.

[0122] Optionally, if the index of the frequency domain unit where the (m - 1)-th hop is located is N m-1 , the terminal may determine the frequency domain unit index where the m-th hop is located based on the frequency domain unit index N where the (m - 1)-th hop is located m-1 and the first frequency domain unit offset offset1, and determine that the frequency domain unit index where the m-th hop is located is (N m-1 + offset1 * n); where n satisfies at least one of the following: n is the smallest positive integer available for the frequency domain unit with the frequency domain unit index (N m-1The smallest positive integer available for the frequency domain unit of (+ offset1 * n); n is less than or equal to the first value; n is a predefined integer.

[0123] Optionally, the terminal determines the frequency domain unit index of the (i + 1)-th hop based on the frequency domain unit index where the first hop is located and the i-th second frequency domain offset in the first frequency domain offset list; where, i is a positive integer;

[0124] Alternatively, the terminal determines the frequency domain unit index of the (i + 1)-th hop based on the frequency domain unit index N1 where the first hop is located and the j-th second frequency domain offset offset j in the first frequency domain offset list, and determines the frequency domain unit index of the (i + 1)-th hop; where, j is greater than or equal to i and satisfies that the frequency domain unit with the frequency domain index of N1 + offset j is the smallest positive integer available.

[0125] Alternatively, the terminal determines the frequency domain unit index of the (g + 1)-th hop based on the frequency domain unit index where the g-th hop is located and the g-th second frequency domain offset in the first frequency domain offset list; where, g is an integer greater than 0;

[0126] Alternatively, the terminal determines the frequency domain unit index of the (g + 1)-th hop based on the frequency domain unit index N g where the g-th hop is located and the x-th second frequency domain offset offset x in the first frequency domain offset list, and determines that the frequency domain unit index of the (g + 1)-th hop is N g + offset x ; where, g is an integer greater than 1, x is greater than or equal to g and satisfies that the frequency domain unit with the frequency domain index of N g + offset x is the smallest positive integer available.

[0127] Alternatively, the terminal determines the frequency domain unit index of the (q + 1)-th hop based on the frequency domain unit index N q where the q-th hop is located and the k-th and p second frequency domain offsets after the k-th in the first frequency domain offset list, and determines that the frequency domain unit index of the (q + 1)-th hop is where, p is the smallest positive integer that satisfies the frequency domain unit index of is available, q is an integer greater than or equal to 1, offset j represents the j-th second frequency domain offset in the first frequency domain offset list, and k - 1 is the index of the second frequency domain offset used to determine the (q - 1)-th hop in the first frequency domain offset list.

[0128] Specifically, the first frequency domain unit offset list includes at least one second frequency domain unit offset, and each second frequency domain unit offset corresponds one-to-one to each hop starting from the second hop.

[0129] When the target information includes the second information and the first frequency domain unit offset list, the terminal may determine the frequency domain unit index of the (i + 1)-th hop based on the frequency domain unit index of the first hop indicated by the second information and the i-th second frequency domain unit offset in the first frequency domain unit offset list; where i is a positive integer. For example, when i = 1, the frequency domain unit index of the first hop is 1, and the first second frequency domain unit offset in the first frequency domain unit offset list is 2. The second frequency domain unit offset represents the offset relative to the frequency domain unit index of the first hop. Then the terminal may determine that the frequency domain unit index of the second hop is 3; when i = 2, the frequency domain unit index of the first hop is 1, and the second second frequency domain unit offset in the first frequency domain unit offset list is 3. Then the terminal may determine that the frequency domain unit index of the third hop is 4.

[0130] Alternatively, the terminal may determine the frequency domain unit index of the (i + 1)-th hop based on the frequency domain unit index N1 of the first hop and the j-th second frequency domain unit offset offset j in the first frequency domain unit offset list; where j is greater than or equal to i and satisfies that the smallest positive integer for which the frequency domain unit with the frequency domain unit index N1 + offset j is available. For example, when i = 1, the frequency domain unit index N1 of the first hop is 1, and the second frequency domain unit offset represents the offset relative to the frequency domain unit index of the first hop. Taking the first second frequency domain unit offset offset1 of the j = 1-th in the first frequency domain unit offset list as 2, the determined frequency domain unit index is 1 + 2 = 3; when the frequency domain unit with the index 3 is available, the frequency domain unit index 3 is determined as the frequency domain unit index of the second hop; or

[0131] when the frequency domain unit with the index 3 is not available, taking the second second frequency domain unit offset offset2 of the j = 2-th in the frequency domain unit offset list as 5, the determined frequency domain unit index is 1 + 6; when the frequency domain unit with the index 6 is not available, repeatedly take the j-th second frequency domain unit offset offset j in the first frequency domain unit list until the determined frequency domain unit is available or the last second frequency domain unit offset in the first frequency domain offset unit list is executed.

[0132] Alternatively, the terminal may determine the frequency domain unit index where the (g + 1)-th hop is located based on the frequency domain unit index where the g-th hop is located and the g-th second frequency domain unit offset in the first frequency domain unit offset list; where g is an integer greater than 0. For example, when g = 1 and the first second frequency domain unit offset in the first frequency domain unit offset list is 2, and the second frequency domain unit offset represents the offset relative to the frequency domain unit index where the previous hop is located, the determined frequency domain unit index is 1 + 2 = 3; if the frequency domain unit with index 3 is available, then the frequency domain unit index where the 2nd hop is located is determined to be 3.

[0133] Alternatively, the terminal may be based on the frequency domain unit index N where the g-th hop is located g and the x-th second frequency domain unit offset offset in the first frequency domain unit offset list x , to determine that the frequency domain unit index where the (g + 1)-th hop is located is N g + offset x ; where g is an integer greater than 0, and x is a positive integer greater than or equal to g and such that the frequency domain unit index is N g + offset x is available. For example, when g = 1, x = 2, the frequency domain unit index where the 1st hop is located is 1, and the 2nd second frequency domain unit offset in the first frequency domain unit offset list is 3, and the second frequency domain unit offset represents the offset relative to the frequency domain unit index where the previous hop is located, then according to the 1st second frequency domain unit offset in the first frequency domain unit offset list, the frequency domain unit index is determined to be 4, and if the frequency domain unit with index 4 is available, then the frequency domain unit index where the 2nd hop is located is determined to be 4.

[0134] Alternatively, the terminal may be based on the frequency domain unit index N where the q-th hop is located q and the k-th and the p second frequency domain unit offsets after the k-th in the first frequency domain unit offset list, to determine that the frequency domain unit index where the (q + 1)-th hop is located is where p is the smallest positive integer that satisfies the frequency domain unit index being

[0135] available, q is an integer greater than or equal to 0, and offset jDenote the j-th second frequency domain unit offset in the first frequency domain unit offset list. k - 1 is the index of the second frequency domain unit offset used for the (q - 1)-th hop in the frequency domain offset list. Assume that the index of the second frequency domain unit offset corresponding to the first hop in the first frequency domain offset list is 0, q = 1, p = 3, k = 1. The second frequency domain unit offset represents the offset relative to the frequency domain unit index where the previous hop is located. The frequency domain unit index N1 where the first hop is located is 1. The first second frequency domain unit offset is 2, the second second frequency domain unit offset is 3, the third second frequency domain unit offset is 4, and the fourth second frequency domain unit offset is 2. Then the frequency domain unit index where the second hop is located is 1 + 2 + 3 + 4 + 2 = 12. Alternatively, the frequency domain unit index N1 where the first hop is located is 1. The first second frequency domain unit offset is 2, the second second frequency domain unit offset is 3, the third second frequency domain unit offset is 4, and the fourth second frequency domain unit offset is 2. Then the frequency domain unit index determined according to the frequency domain unit index where the first hop is located and the first second frequency domain unit offset is 3. The frequency domain unit with index 3 is unavailable. Then, on the basis of index 3, offset by the second second frequency domain unit offset, and the determined frequency domain unit index is 6. The frequency domain unit with index 6 is unavailable. Then, on the basis of index 6, offset by the third second frequency domain unit offset, and the determined frequency domain unit index is 10. The frequency domain unit with index 10 is available. Then, the frequency domain unit index where the second hop is located is determined to be 10.

[0136] In an embodiment of the present application, the terminal determines the frequency domain unit index of each hop after the second hop through the frequency domain unit index where the first hop is located and the second frequency domain unit offset in the first frequency domain unit offset list, so that the terminal performs frequency hopping transmission between different frequency domain units, thereby obtaining sufficient frequency domain diversity gain or increasing the anti-interference ability, and improving the effectiveness and performance of the communication system.

[0137] Optionally, when the frequency domain unit index obtained based on the first frequency domain unit offset or the second frequency domain unit offset is greater than the maximum frequency domain unit index in the configured or activated frequency domain units, the terminal uses wrap around or modulo operation to determine the frequency domain unit index of each hop starting from the second hop.

[0138] Specifically, when the frequency domain unit index obtained based on the first frequency domain unit offset or the second frequency domain unit offset is greater than the maximum frequency domain unit index in the configured or activated frequency domain units, the terminal can use wrap around or modulo operation to determine the frequency domain unit index of each hop starting from the second hop. For example, when exceeds the maximum index of the UL available or activated frequency domain units, the terminal uses the wrap around operation to determine such as Among them, represents the number of uplink configured or available or active frequency domain units.

[0139] Optionally, when the target information includes the at least one frequency domain unit pair, the terminal determines, based on the target information, the frequency domain unit where each hop of the first transmission is located, including:

[0140] The terminal determines the frequency domain unit index where each hop starting from the second hop is located based on each of the frequency domain unit pairs; the terminal determines the frequency domain unit where each hop of the at least two hops of the first transmission is located based on the frequency domain unit index where the first hop is located and the frequency domain unit index where each hop starting from the second hop is located.

[0141] Specifically, since each frequency domain unit pair is used to indicate the frequency domain unit associated with the frequency domain unit where the first hop is located, the terminal can determine the frequency domain unit index where each hop starting from the second hop is located based on each frequency domain unit pair, that is, respectively use the frequency domain unit index associated with the frequency domain unit where the first hop is located as the frequency domain unit index where each hop starting from the second hop is located. The terminal can determine the frequency domain unit where each hop of the at least two hops of the first transmission is located according to the frequency domain unit index where the first hop is located and the frequency domain unit index where each hop starting from the second hop is located.

[0142] For example, the base station configures or indicates 3 frequency domain unit pairs for the first transmission. Among them, frequency domain unit pair 1 indicates the frequency domain unit where the second hop associated with the frequency domain unit where the first hop is located is located; frequency domain unit pair 2 indicates the frequency domain unit where the third hop associated with the frequency domain unit where the first hop is located is located; frequency domain unit pair 3 indicates the frequency domain unit where the fourth hop associated with the frequency domain unit where the first hop is located is located. The terminal can determine the frequency domain unit where the second hop is located, the frequency domain unit where the third hop is located, and the frequency domain unit where the fourth hop is located according to the frequency domain unit where the first hop is located and the 3 frequency domain unit pairs, so as to determine the frequency domain unit where the first hop is located, the frequency domain unit where the second hop is located, the frequency domain unit where the third hop is located, and the frequency domain unit where the fourth hop is located.

[0143] In the embodiments of the present application, the terminal determines the frequency domain unit index where each hop is located through each frequency domain unit pair, so that the terminal performs frequency hopping transmission between different frequency domain units, thereby obtaining a relatively large frequency domain diversity gain or increasing the anti-interference ability, and improving the effectiveness and performance of the communication system.

[0144] Optionally, when the target information includes the first frequency domain unit list, the terminal determines, based on the target information, the frequency domain unit where at least one hop of the first transmission is located, including:

[0145] The terminal determines the frequency domain unit index of each hop starting from the second hop in sequence according to the frequency domain unit index in the first frequency domain unit list, in the order corresponding to the frequency domain unit index of each hop starting from the second hop; the terminal determines the frequency domain unit where at least one hop of the at least two hops of the first transmission is located based on the frequency domain unit index where the first hop is located and the frequency domain unit index of each hop starting from the second hop.

[0146] Specifically, the first frequency domain unit list includes multiple frequency domain unit indexes, and each frequency domain unit index in the first frequency domain unit list corresponds to the frequency domain unit index of each hop starting from the second hop. The terminal can determine the frequency domain unit index of each hop starting from the second hop in sequence according to the order corresponding to the frequency domain unit index of each hop starting from the second hop in the first frequency domain unit list. The terminal then determines the frequency domain unit where each hop of the at least two hops is located based on the frequency domain unit index where the first hop is located and the frequency domain unit index of each hop starting from the second hop.

[0147] For example, the first frequency domain unit list includes 3 frequency domain unit indexes. Among them, the first frequency domain unit index corresponds to the frequency domain unit index of the second hop, the second frequency domain unit index corresponds to the frequency domain unit index of the third hop, and the third frequency domain unit index corresponds to the frequency domain unit index of the fourth hop. The terminal can determine that the frequency domain unit index of the second hop is the first frequency domain unit index, the frequency domain unit index of the third hop is the second frequency domain unit index, and the frequency domain unit index of the fourth hop is the third frequency domain unit index in sequence according to the order corresponding to the frequency domain unit index of each hop starting from the second hop in the first frequency domain unit list.

[0148] Optionally, the terminal determines the frequency domain unit index of at least one hop starting from the second hop based on the first frequency domain unit list, in the order corresponding to the frequency domain unit index of each hop starting from the second hop, including:

[0149] When the first target frequency domain unit determined by the terminal in sequence according to the order corresponding to the frequency domain unit index of each hop starting from the second hop in the first frequency domain unit list is unavailable, the terminal sequentially moves to the next frequency domain unit of the first target frequency domain unit until the determined frequency domain unit is available or until the last frequency domain unit in the first frequency domain unit list.

[0150] Specifically, the first target frequency-domain unit is an unavailable frequency-domain unit in the first frequency-domain unit list. When the first target frequency-domain unit determined by the terminal in the order corresponding to the frequency-domain unit indexes of each hop starting from the second hop in sequence according to the frequency-domain unit indexes in the first frequency-domain unit list is unavailable, the terminal can sequentially move to the next frequency-domain unit of the first target frequency-domain unit. When the next frequency-domain unit of the first target frequency-domain unit is unavailable, the next frequency-domain unit is used as the first target frequency-domain unit, and then move to the next frequency-domain unit of this first target frequency-domain unit until the determined frequency-domain unit is available or the last frequency-domain unit in the first frequency-domain unit list is reached.

[0151] Alternatively, the terminal respectively determines corresponding candidate frequency-domain units according to the first frequency-domain unit list, and selects the first N available frequency-domain units from the candidate frequency-domain units to be respectively used for the second hop, the third hop, …, the (N + 1)-th hop of the first transmission.

[0152] For example, the first frequency-domain unit list includes 3 frequency-domain unit indexes. When the frequency-domain unit corresponding to the first frequency-domain unit index is available, the terminal determines the first frequency-domain unit index as the frequency-domain unit index where the second hop is located; when the frequency-domain unit corresponding to the first frequency-domain unit index is unavailable, the terminal determines whether the frequency-domain unit corresponding to the second frequency-domain unit index is available; when the frequency-domain unit corresponding to the second frequency-domain unit index is available, the terminal determines the second frequency-domain unit index as the frequency-domain unit index where the second hop is located.

[0153] In the embodiments of the present application, the terminal determines the frequency-domain unit index where each hop is located through the first frequency-domain unit list, so that the terminal performs frequency hopping transmission between different frequency-domain units, thereby obtaining a relatively large frequency-domain diversity gain or increasing the anti-interference ability, and improving the effectiveness and performance of the communication system.

[0154] Optionally, when the target information includes the second frequency-domain unit list, the terminal determines the frequency-domain unit where at least one hop of the first transmission is located based on the target information, including:

[0155] The terminal determines the frequency-domain unit where each hop of the at least two hops of the first transmission is located based on the second frequency-domain unit list in the order of the frequency-domain unit indexes in the second frequency-domain unit list;

[0156] Or,

[0157] When the second target frequency-domain unit determined based on the order of the frequency-domain unit indexes in the second frequency-domain unit list is unavailable, the terminal sequentially moves to the next frequency-domain unit of the second target frequency-domain unit until the determined frequency-domain unit is available or the last frequency-domain unit in the second frequency-domain unit list is reached.

[0158] Specifically, the second frequency domain unit list includes multiple frequency domain unit indexes, and each frequency domain unit index in the second frequency domain unit list respectively corresponds to the frequency domain unit index where each hop is located. For example, the second frequency domain unit list includes 3 frequency domain unit indexes, where the 1st frequency domain unit index corresponds to the frequency domain unit index where the first hop is located, the 2nd frequency domain unit index corresponds to the frequency domain unit index where the second hop is located, and the 3rd frequency domain unit index corresponds to the frequency domain unit index where the third hop is located. The terminal can determine the frequency domain unit where each hop is located according to the second frequency domain unit list.

[0159] The terminal can determine the frequency domain unit where each hop in at least two hops of the first transmission is located in the order of the frequency domain unit indexes in the second frequency domain unit list. For example, the terminal determines that the 1st frequency domain unit index is the frequency domain unit index where the first hop is located, the 2nd frequency domain unit index is the frequency domain unit index where the second hop is located, and the 3rd frequency domain unit index is the frequency domain unit index where the third hop is located.

[0160] Alternatively, the second target frequency domain unit is an unavailable frequency domain unit in the second frequency domain unit list. When the second target frequency domain unit determined in the order of the frequency domain unit indexes in the second frequency domain unit list is unavailable, the terminal can sequentially move to the next frequency domain unit of the second target frequency domain unit. When the next frequency domain unit of the second target frequency domain unit is unavailable, the next frequency domain unit is used as the second target frequency domain unit, and then move to the next frequency domain unit of this second target frequency domain unit until the determined frequency domain unit is available or the last frequency domain unit in the second frequency domain unit list.

[0161] For example, the second frequency domain unit list includes 4 frequency domain unit indexes. When the frequency domain unit corresponding to the 1st frequency domain unit index is available, the terminal determines the 1st frequency domain unit index as the frequency domain unit index where the first hop is located; when the frequency domain unit corresponding to the 1st frequency domain unit index is unavailable, the terminal determines whether the frequency domain unit corresponding to the 2nd frequency domain unit index is available; when the frequency domain unit corresponding to the 2nd frequency domain unit index is available, the terminal determines the 2nd frequency domain unit index as the frequency domain unit index where the first hop is located; when the frequency domain unit corresponding to the 3rd frequency domain unit index is available, the terminal determines the 3rd frequency domain unit index as the frequency domain unit index where the second hop is located.

[0162] Alternatively, the terminal respectively determines the corresponding candidate frequency domain units according to the second frequency domain unit list, and selects the first M available frequency domain units from the candidate frequency domain units for the first hop, the second hop,..., the Mth hop transmissions of the first transmission respectively.

[0163] In an embodiment of the present application, the terminal determines the frequency domain unit index where each hop is located through a second list of frequency domain units, enabling the terminal to perform frequency hopping transmission between different frequency domain units, thereby obtaining a larger frequency domain diversity gain or increasing the anti-interference ability and improving the effectiveness and performance of the communication system.

[0164] Optionally, when any frequency domain unit determined by the terminal based on the target information is unavailable, the terminal performs transmission according to any of the following: the terminal cancels the transmission of the first transmission corresponding to the hop in the any frequency domain unit; the terminal switches the transmission of the first transmission corresponding to the hop in the any frequency domain unit to another available frequency domain unit for transmission; the terminal defers the transmission of the first transmission corresponding to the hop in the any frequency domain unit to an available frequency domain unit corresponding to another available time unit for transmission.

[0165] Specifically, when any frequency domain unit determined by the terminal based on the target information is unavailable, the terminal may cancel the transmission of the first transmission corresponding to the hop in any frequency domain unit, or the terminal may switch the transmission of the first transmission corresponding to the hop in any frequency domain unit to another available frequency domain unit according to a predefined rule and / or a base station indication for transmission, or the terminal defers the transmission of the first transmission corresponding to the hop in the first frequency domain unit to an available frequency domain unit corresponding to another available time unit for transmission.

[0166] Optionally, when only one of the at least two hops of the first transmission has an available frequency domain unit or the number of available frequency domain units is less than the first value, the terminal falls back from the frequency hopping mode to a non-frequency hopping mode or a non-frequency domain unit hopping mode.

[0167] Optionally, the first value is determined based on at least one of the following: the maximum number of frequency hops; network indication; protocol predefined.

[0168] For example, if the first transmission includes 2 hops, the frequency domain unit where the first hop is located is available, and the frequency domain unit where the second hop is located is unavailable, then the terminal may fall back from the frequency hopping mode to a non-frequency hopping mode or a non-frequency domain unit hopping mode. Or, if the first transmission includes 3 hops, the maximum number of frequency hops configured or indicated by the base station is 3, the frequency domain units where the first hop and the second hop are located are available, and the frequency domain unit where the third hop is located is unavailable, then the terminal may fall back from the frequency hopping mode to a non-frequency hopping mode or a non-frequency domain unit hopping mode.

[0169] Next, the frequency hopping transmission method provided by the embodiments of the present application will be further described through specific embodiments.

[0170] Embodiment 1

[0171] Assume that a cell consists of 3 frequency-domain units, and the sizes of these 3 frequency-domain units (frequency-domain unit index 0, frequency-domain unit index 1, frequency-domain unit index 2) are 5 MHz, 10 MHz, and 5 MHz respectively. The base station can configure some or all of the frequency-domain units for uplink transmission, and the base station can also activate or deactivate these 3 frequency-domain units. It should be noted that in Figures 4 to 8 it is represented by taking the frequency-domain unit as the BWP for illustration, where the frequency-domain unit can be any one of bandwidth (band), carrier, subband, and BWP.

[0172] For each PUCCH resource, the base station configures (for example, according to the frequency-domain unit where the PUCCH resource is configured, or configures the corresponding frequency-domain unit for each (per) PUCCH resource, or for channel state information (CSI), scheduling request (SR), or semi-persistent scheduling (SPS) hybrid automatic repeat request acknowledgement (HARQ-ACK) reporting, indicates the frequency-domain unit where CSI, SR, SPS, or HARQ-ACK reporting is located) or indicates (for example, for dynamically scheduled HARQ-ACK, indicates the frequency-domain unit where HARQ-ACK is located through scheduling or activating DCI) the frequency-domain unit index of the first hop (the frequency-domain unit index can be an ID), and configures or indicates the frequency-domain unit index of the second hop. For example, the PUCCH resource is configured in the following way:

[0173] Method 1: The base station configures the frequency-domain unit index of each hop of each PUCCH transmission through higher-layer parameters. Figure 4 is one of the schematic diagrams of the frequency-domain unit index of each hop of PUCCH transmission provided by the embodiments of the present application. As Figure 4 shown, the base station configures the first hop of a PUCCH resource in BWP0 (assuming the frequency-domain unit is BWP0 in this embodiment) and the second hop in BWP1 through higher-layer parameters. For example, the base station configures the frequency-domain unit ID of each hop when configuring each PUCCH resource (assuming IE PUCCHresource is used). As shown below, where BWP0 represents the BWP ID where the first hop of the PUCCH resource is located, and BWP1 represents the BWP ID where the second hop of the PUCCH resource is located.

[0182] Method 2: The base station configures or indicates the frequency hopping offset of PUCCH transmission. In one implementation, the base station indicates (such as higher layer configuration or DCI indication) a frequency hopping offset; in another implementation, the base station indicates (such as higher layer configuration or DCI indication) a list of frequency domain unit offsets. For example, the terminal determines the frequency domain unit where the first hop of PUCCH transmission is located through base station indication, higher layer configuration, or predefined rules, and determines the frequency domain unit where each hop starting from the second hop is located according to the frequency hopping offset. Among them, for the frequency hopping offset offset, it can be the offset relative to the frequency domain unit index where the first hop is located, or the offset relative to the frequency domain unit index where the previous hop is located, or the number of available or active frequency domain units offset in the available or active frequency domain units relative to the frequency domain unit index where the previous hop is located.

[0183] Figure 5 This is the second schematic diagram of the frequency domain unit index where each hop of PUCCH transmission provided by the embodiments of the present application. As Figure 5 shown, the base station determines through higher layer parameter configuration, DCI indication, or predefined rules that the frequency domain unit where the first hop of PUCCH transmission is located is BWP0, and the frequency hopping offset is 2. Then the terminal can determine that the frequency domain unit where the second hop is located is BWP2. Figure 6 This is the third schematic diagram of the frequency domain unit index where each hop of PUCCH transmission provided by the embodiments of the present application. As Figure 6As shown, the base station determines that the frequency domain unit where the first hop of PUCCH transmission is located is BWP1 through high-layer parameter configuration, DCI indication, or predefined rules, and the frequency hopping offset is 1. Then the terminal can determine that the frequency domain unit is BWP2. Since BWP2 is unavailable, the terminal can continue to offset by 1 frequency domain unit to determine BWP0. When the corresponding resources on BWP0 are available, it determines that the frequency domain unit where the second hop is located is BWP0.

[0184] Method 3: The base station configures at least one pair of frequency domain units or a list of frequency domain units, and configures or indicates a pair of frequency domain units or a list of frequency domain units for each PUCCH resource. Figure 7 It is the fourth schematic diagram of the frequency domain unit index where each hop of PUCCH transmission provided by the embodiments of the present application. As Figure 7 shown, the base station configures a pair of frequency domain units for a PUCCH through high-layer configuration signaling. The terminal determines that the frequency domain unit where the first hop of PUCCH transmission is located is BWP0 according to this pair of frequency domain units, and the frequency domain unit where the second hop is located is BWP1.

[0185] For example, the base station configures a pair of frequency domain units in the following manner. Each pair of frequency domain units can be identified by a pair of frequency domain unit IDs (BWP-pairId), and each pair of frequency domain units can be configured with two frequency domain unit indexes.

[0186] BWP pair{

[0187] BWP-pairId

[0188] BWPID1

[0189] BWPID2

[0190] }

[0191] For example, when the base station configures each PUCCH resource, it configures the corresponding pair of frequency domain units for this PUCCH resource. In addition, the base station can also indicate the BWP-pairId corresponding to each PUCCH resource through dynamic signaling.

[0199] Or

[0200] For example, the base station configures a list of frequency domain units list in the following way, where each list of frequency domain units list can be identified by a list ID of the frequency domain unit list (such as the parameter BWP-listId), and each list of frequency domain units list can configure multiple frequency domain unit indices.

[0208] For example, when the base station configures each PUCCH resource, it configures the corresponding list of frequency domain units for that PUCCH resource. The base station can also indicate the BWP-listId corresponding to each PUCCH resource through dynamic signaling.

[0215] Embodiment 2

[0216] In the prior art, the transmission of the Physical Downlink Shared Channel (PDSCH) supports discontinuous Physical Resource Block (PRB) allocation within one Bandwidth Part (BWP), so frequency hopping in the frequency domain does not need to be supported. For sub-3G spectrum resources, they are relatively scattered, and the frequency domain resources of a single band are relatively narrow. If the PDSCH resource allocation is restricted within one band, frequency diversity gain cannot be obtained or the obtained frequency diversity gain is limited.

[0217] In order to obtain better frequency diversity gain and anti-interference effect, frequency hopping transmission can also be adopted for downlink transmission, and different hops of one transmission can be carried out in different bands. For example, the base station configures or enables downlink transmission to perform frequency hopping transmission through high-layer signaling. In addition, since the number of Resource Blocks (RBs) allocated for PDSCH resources is usually relatively large, when performing frequency hopping transmission, the base station ensures that each frequency domain unit where each hop is located, which is configured or indicated, has enough RBs for PDSCH transmission. Or when the terminal determines the frequency domain unit according to the configuration or indication of the base station, if the frequency domain resources included in this frequency domain unit cannot meet the PDSCH transmission, that is, this frequency domain unit is unavailable, the terminal can not perform frequency hopping or find another frequency domain unit that meets the requirements for transmission.

[0218] Embodiment 3

[0219] Figure 8 FIG. 5 is a schematic diagram of the frequency domain unit index where each hop of the PUCCH transmission provided by the embodiment of the present application is located. As Figure 8 shown, for a PUCCH or PUSCH transmission, the terminal can determine to transmit the first hop in BWP0 and the second hop in BWP2 according to the base station configuration or indication. However, PUCCH or PUSCH cannot be transmitted at the frequency domain position corresponding to the second hop. In Figure 8 , if the symbol position where PUCCH or PUSCH is located is configured as a DL symbol, then in one embodiment, the terminal cancels the frequency hopping transmission and transmits the first hop and the second hop in BWP0; in another embodiment, the terminal switches the second hop to another frequency domain unit for transmission according to a predefined rule. For example, the second hop is transmitted on the available or active BWP with the largest interval from the frequency domain unit where the first hop is located ( Figure 8 is BWP1 in
