[0058] Step 202: The terminal performs data transmission or reception according to the frequency hopping configuration information based on the frequency domain unit.

[0059] The data transmission method of this application configures frequency hopping configuration information based on frequency domain units for physical channels or signals. Frequency hopping based on the frequency domain unit frequency hopping configuration information can obtain frequency diversity gain, thereby improving the performance of receiving downlink signals and increasing system capacity.

[0060] Optionally, the frequency hopping configuration information based on frequency domain units includes at least one of the following:

[0061] Frequency hopping information;

[0062] Time-domain frequency hopping information;

[0063] Airspace frequency hopping information;

[0064] Frequency retuning time refers to the switching time for a terminal to hop from a first frequency domain unit to a second frequency domain unit.

[0065] Further optionally, the frequency domain frequency hopping information includes at least one of the following:

[0066] Frequency hopping range;

[0067] Frequency hopping interval;

[0068] Wherein, the frequency hopping range is the frequency difference between the lowest subcarrier of the lowest frequency domain unit and the highest subcarrier of the highest frequency domain unit, and the frequency hopping range includes X frequency domain units, where X is determined based on at least one of system bandwidth and terminal capability; the frequency hopping interval is the smallest frequency domain granularity for frequency hopping between two frequency domain units. The frequency hopping interval is determined based on at least one of system bandwidth and terminal capability, where the terminal capability can be the frequency domain unit bandwidth supported by the terminal. Wherein, X≥2.

[0069] X’s instructions or notifications are implemented through at least one of the following: SI, RRC, MAC CE, DCI.

[0070] The indication or notification of frequency hopping intervals is achieved through at least one of the following: SI, RRC, MAC CE, DCI.

Optionally, Y consecutive time units can be used for joint channel estimation or DMRS binding across slots or subslots, or multiple time units can be continuously scheduled for transmitting PUSCH or PDSCH.

[0072] like Figure 3 As shown, for example, the frequency hopping range includes 4 BWPs, and the frequency domain position is switched every 4 time units.

[0073] Optionally, the spatial frequency hopping information includes:

[0074] Transmission configuration indications or quasi-co-located QCLs assume that the same or different values ​​are in the same frequency domain unit.

[0075] Alternatively, the transmission configuration indication or quasi-co-address QCL assumes that the frequency domain units are the same or different.

[0076] Optionally, the frequency retuning time is determined based on at least one of the following:

[0079] The first N symbols of the second frequency domain unit have a time length that is less than the frequency readjustment time threshold.

[0080] Terminal implementation;

[0081] The gap reserved during base station scheduling.

[0082] In this embodiment, the frequency readjustment time applies to at least one of the following scenarios (P not equal to Q):

[0086] Scenario 4: The UE hops from PUSCH / PDSCH frequency domain unit #P to PUCCH / PDCCH frequency domain unit #Q;

[0087] Scenario 5: The UE hops from PRACH frequency domain unit #P to PRACH frequency domain unit #Q.

[0088] The definition of frequency readjustment time may differ in different scenarios.

[0089] Optionally, the step of transmitting or receiving data based on the frequency hopping configuration information based on the frequency domain unit includes at least one of the following:

[0090] Data transmission or reception is performed based on the frequency hopping configuration information of the frequency domain unit where the first transmission occurs;

[0091] Data transmission or reception is performed based on the frequency hopping configuration information of the physical channel or signal scheduled on the current frequency domain unit.

[0092] Further optionally, the first transmission is the first transmission indicated by downlink control information (DCI);

[0093] Alternatively, the first transmission may refer to the first actual transmission. That is, when calculating the BWP activation time, the ratio of uplink and downlink time slots indicated by the Slot Format Indication (SFI) is considered, and only time slots capable of actual transmission are counted as BWP activation time. For example, if the SFI configuration is DDDSU, during PDSCH frequency hopping transmission, uplink time slot U is not included in the BWP activation time. The calculation method for the downlink activation time in the special time slot S is determined based on the configuration within the time slot and the time unit granularity of the BWP frequency hopping activation time.

[0094] It should be noted that the specific frequency domain unit used for frequency hopping configuration depends on the base station configuration and / or the terminal's capabilities.

[0095] The data transmission method of this application will be described below with reference to specific embodiments.

[0096] Assuming the aforementioned frequency domain unit is a BWP, after the terminal accesses the cell, the base station configures the relevant parameters for BWP handover for the terminal through higher-layer signaling.

[0097] 1. Configure the candidate BWP set and determine the frequency hopping range.

[0098] The base station is configured with multiple BWPs for the terminal. The number of BWPs can be determined based on the cell system bandwidth or the number of BWPs that the RedCap terminal needs to support as specified in the protocol.

[0099] Alternatively, the Red Cap terminal can proactively report its frequency hopping capability, and the base station can configure the corresponding BWP set for it according to the terminal's frequency hopping capability.

[0100] The configuration parameters of the candidate BWP can reuse the configuration parameters of the existing protocol BWP and be configured to the terminal using RRC signaling.

[0101] 2. The base station configures BWP handover parameters for the terminal, including the transmission mode for frequency hopping or handover between BWPs (the order in which BWPs are activated, the transmission time length of each BWP when activated, and the BWP handover time).

[0102] The frequency hopping transmission mode between BWPs can be executed periodically, or configured dynamically or semi-statically to the terminal via DCI, MAC CE signaling. The period of the BWP frequency hopping transmission mode is greater than or equal to the sum of the activation times of all BWPs; if it is greater, it indicates idle transmission time.

[0103] The frequency hopping transmission mode between BWPs involves one or more candidate BWPs per cycle or transmission. These BWPs are activated sequentially at different transmission times or slots according to their activation order, transmitting uplink or downlink signals. The transmission time of each activated BWP is indicated by the length of the transmission time at activation, typically at the granularity of symbols, time slots, or subframes. The handover timing between BWPs can be specified by the protocol or by the terminal actively reporting its handover capability. Specifically, if the frequency hopping transmission mode between BWPs contains only one BWP, it indicates a non-frequency hopping transmission mode.

[0104] During frequency hopping between BWPs, multiple consecutive time units within the active period of a BWP have the same Transmission Configuration Indicator (TCI) configuration. Different BWPs have the same TCI configuration during frequency hopping transmission. The TCI used for BWP frequency hopping transmission is configured by the base station via RRC signaling or DCI. Alternatively, if the terminal configures different TCIs for different BWPs during BWP configuration, the terminal communicates according to the configured TCI after BWP handover. The TCI can be applied to all physical channels of the terminal, or to the physical channel indicated by the configuration information.

[0105] The base station can configure multiple BWP frequency hopping transmission modes for the terminal via RRC signaling. The terminal can then communicate or transmit through the corresponding physical channels according to one or more of these configurations. The BWP frequency hopping transmission modes can be activated periodically via RRC signaling, or they can be activated dynamically or semi-statically via MAC CE or DCI.

[0106] 3. The base station configures the corresponding BWP handover transmission mode (i.e., frequency hopping configuration information) for each physical channel of the terminal.

[0107] Different uplink and downlink physical channels of the terminal can be configured with different or the same BWP handover transmission mode. If all uplink and downlink physical channels use the same BWP handover transmission mode, the terminal performs BWP handover periodically according to the BWP handover transmission mode.

[0108] Optionally, the base station configures different BWP handover transmission modes for different physical channels of the terminal. The BWP handover transmission mode can be configured on at least one of the following physical channels: PDCCH CSS Type 0 / 0A / 1 / 2; PDCCH CSS Type 3; PDCCH USS; PDSCH; Non-CD SSB; CSI-RS; PUSCH; PUCCH; PRACH; SRS. Alternatively, this scheme is not applicable (or can only be applied to) at least one of the following channels or signals: PDCCH CSS Type 0 / 0A / 1 / 2; PDCCH CSS Type 3; PDCCH USS; PDSCH; SSB; CSI-RS; PRACH.

[0109] For example, in a Frequency Division Duplex (FDD) terminal, the uplink physical channel is transmitted according to BWP handover mode 1, and the downlink physical channel is transmitted according to BWP handover mode 2. As another example, the PDCCH CSS listens according to BWP handover mode 1, the PDCCH CSS listens on a fixed BWP (initial downlink BWP), and the PDSCH is transmitted according to either the DCI-scheduled BWP handover mode or the periodic BWP handover mode 2.

[0110] 4. The terminal receives downlink signals and / or sends uplink signals according to the BWP switching transmission mode.

[0111] Frequency hopping or handover of BWPs in different time slots and on different physical channels requires a time length of Y (if different BWPs have different subcarrier SCS bandwidths, resulting in different symbol lengths or different frequency readjustment times for different BWPs; different frequency handover distances between two BWPs in a single BWP frequency hopping or handover also result in different frequency readjustment times. The frequency readjustment time Y is determined by the above-mentioned influencing factors). The start time of BWP frequency hopping or handover is determined separately according to the characteristics of different physical channels. The terminal can perform BWP handover based on the time reserved by the base station or according to the rules defined in the protocol.

[0112] Specifically, for PDCCH, the terminal periodically listens to PDCCH according to the base station configuration at the listening time. If the PDCCH carries the terminal's scheduling information, the terminal performs frequency hopping and scheduling behavior from PDCCH to PDSCH or from PDCCH to PUSCH, which belongs to the BWP handover between different physical channels. If the PDCCH needs to listen to multiple PDCCH transmission opportunities, and the multiple PDCCH transmission opportunities correspond to different BWPs according to the BWP frequency hopping transmission mode, the terminal performs BWP handover at any time after listening to the last PDCCH listening opportunity on the current BWP and before the start of the first PDCCH listening opportunity on the new BWP, ensuring that the BWP handover is completed before the start of the PDCCH listening opportunity on the new BWP. If different search spaces of the PDCCH are configured with different BWP frequency hopping transmission modes, such as PDCCH CSS and PDCCH USS being configured with different BWP frequency hopping transmission modes; if the terminal needs to listen to PDCCH CSS and PDCCH USS during certain time periods, but the two PDCCHs are not in the same BWP, the terminal selects one of the two BWPs to listen to according to the protocol (for example, if PDCCH CSS has a higher priority than PDCCH USS, the terminal switches to the BWP where PDCCH CSS is located to listen). Optionally, the terminal listens to PDCCH CSS and PDCCH USS within the search space of the BWPs determined above.

[0113] For PDSCH, the terminal receives downlink data in the corresponding time slot according to the base station's configuration. When PDSCH requires BWP handover, if the PDSCH time slots before and after the BWP handover are discontinuous, and no other signals need to be received or transmitted before the BWP handover and after the PDSCH transmission ends, and no other signals need to be received or transmitted after the BWP handover and before the PDSCH transmission begins, the terminal can complete the BWP handover within the interval. If the PDSCH time slots before and after the BWP handover are continuous, the terminal completes the BWP handover within the first M symbols of the first time slot after the BWP handover and starts receiving PDSCH from the (M+1)th symbol (M symbols can be included within the symbol range of PDCCH); or, the terminal performs the BWP handover in the last M symbols of the last time slot before the BWP handover; or, the terminal completes the BWP handover in the last M1 symbols of the last time slot before the BWP handover and the first M2 symbols of the first time slot after the BWP handover (M = M1 + M2, M2 is included within the symbol range of PDCCH). Here, M is determined based on the maximum value of the frequency readjustment time.

[0114] For PUCCH and PUSCH, if the PUCCH / PUSCH time slots before and after the BWP handover are discontinuous, and no other signals need to be received or transmitted before the BWP handover and after the PUCCH / PUSCH transmission ends, and no other signals need to be received or transmitted after the BWP handover and before the PUCCH / PUSCH transmission begins, the terminal can complete the BWP handover within the interval. If the PUCCH / PUSCH time slots before and after the BWP handover are continuous, the terminal completes the BWP handover within the first M symbols of the first time slot after the BWP handover and starts transmitting PUCCH / PUSCH from the M+1th symbol; or, the terminal performs the BWP handover within the last M symbols of the last time slot before the BWP handover; or, the terminal completes the BWP handover within the last M1 symbols of the last time slot before the BWP handover and the first M2 symbols of the first time slot after the BWP handover (M = M1 + M2).

[0115] For BWP handover from PDCCH to PDSCH, if it is intra-slot scheduling or inter-slot scheduling, and PDCCH and PDSCH are in the same BWP, the terminal does not need to perform BWP handover. After receiving the PDSCH of the current BWP, the terminal switches to another BWP to receive subsequent PDSCH according to the above-mentioned PDSCH BWP handover behavior. If it is inter-slot scheduling, and PDCCH and PDSCH are in different BWPs, the terminal completes the BWP handover after the PDCCH ends and before the PDSCH transmission begins. The total handover time is the PDCCH parsing time and the BWP handover time. The BWP handover behavior occurs after PDCCH listening in the time slot where PDCCH is located.

[0116] For BWP handover from downlink to uplink, the terminal utilizes the switching interval between uplink and downlink channels to complete the BWP handover operation.

[0117] For BWP handover from uplink to downlink, the terminal performs BWP handover in the last M symbols of the last time slot of the uplink BWP.

[0118] The data transmission method of this application configures frequency hopping configuration information based on frequency domain units for physical channels or signals. Frequency hopping based on the frequency domain unit frequency hopping configuration information can obtain frequency diversity gain, thereby improving the performance of receiving downlink signals and increasing system capacity.
