However, the exemplary embodiments may be embodied in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art.

In the description of the present disclosure, unless otherwise indicated, "/" means "or" and, for example, a/B may mean a or B. "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. Furthermore, "at least one" means one or more, and "a plurality" means two or more. The terms "first," "second," and the like do not limit the number and order of execution, and the terms "first," "second," and the like do not necessarily differ.

A terminal referred to in embodiments of the present disclosure is a device that provides voice and/or data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem. The terminals may be mobile terminals such as mobile telephones (or "cellular" telephones) and computers with mobile terminals, which may be, for example, portable, pocket, hand-held, computer-built-in or car-mounted mobile devices which exchange voice and/or data with radio access networks. A Terminal may also be referred to as a Subscriber Unit (Subscriber Unit), a Subscriber Station (Subscriber Station), a Mobile Station (Mobile Station), a Remote Station (Remote Station), an AP (Wireless Access Point ), a Remote Terminal (Remote Terminal), an Access Terminal (Access Terminal), a User Terminal (User Terminal), a User Agent (User Agent), or a UE (User Equipment), without limitation.

Fig. 1 schematically illustrates a flow chart of a wireless communication method according to an embodiment of the disclosure. As shown in fig. 1, the method provided by the embodiment of the present disclosure may include the following steps.

In step S110, the network device sends a signaling to the terminal, so as to configure the repeated transmission parameters of the frequency domain and/or the time domain for the terminal through the signaling, so that the terminal repeatedly transmits uplink data to the network device based on the repeated transmission parameters of the frequency domain and/or the time domain.

The network device in the embodiments of the present disclosure may be a base station.

In an exemplary embodiment, the network device configures the terminal with the frequency domain and/or time domain retransmission parameters through the signaling, so that the terminal retransmits uplink data to the network device on at least one of the following frequency domain and/or time domain resources based on the frequency domain and/or time domain retransmission parameters: a single carrier; and (3) multi-carrier waves.

In an exemplary embodiment, the signaling may be at least one of the following: downlink control information DCI (Downlink Control Information) signaling, control element MAC CE (Media Access Control Address Control Element) signaling for medium access control, radio resource control RRC (Radio Resource Control) signaling.

In an exemplary embodiment, the single carrier may include an active bandwidth portion and/or an initial bandwidth portion.

In an exemplary embodiment, the multi-carrier may be a plurality of carriers in carrier aggregation (carrier aggregation, CA) and/or multi-connection and/or spectrum aggregation (may also be referred to as frequency aggregation); the signaling and the uplink data which are repeatedly transmitted are in the same carrier wave and/or in different carrier waves. The method provided by the embodiment of the disclosure can be applied to application scenes such as CA, multi-connection, frequency aggregation and the like.

The signaling and the uplink data that are repeatedly transmitted are on the same carrier, for example, the repeated transmission of the uplink data is performed on carrier 2 and carrier 3 through the DCI indication on carrier 1.

The signaling and the uplink data that are repeatedly transmitted are indicated on different carriers, for example, on carrier 1 through DCI to perform repeated transmission of uplink data on carrier 1, carrier 2 and carrier 3.

A connection mode in which service transmission is simultaneously provided to a terminal through a plurality of (two or more) access networks is called a multi-connection mode. The connection mode when the terminal is provided with service transmission simultaneously through two access networks is called Multi-radio dual connection (Multi-Radio Dual Connectivity, MR-DC) or dual connection mode.

For example, in the initial stage of a fifth generation (5G) mobile communication system, since a fourth generation (4G) mobile communication system and a 5G New Radio (NR) network coexist, in order to fully utilize the existing 4G network, an operator deploys a UMTS terrestrial Radio access network (Evolved UMTS Terrestrial Radio Access Network, E-UTRAN) and an NR network through which a service is simultaneously provided for a terminal. In addition, two 5G NR access networks can be deployed to provide service transmission for the terminal at the same time.

In an exemplary embodiment, the frequency domain and/or time domain repeated transmission parameter may include a frequency domain repeated transmission number Q, where Q is a positive integer greater than or equal to 1, so that the terminal repeatedly transmits the uplink data Q times to the network device on a time-frequency resource configured by the frequency domain and/or time domain repeated transmission parameter.

In an exemplary embodiment, a single transmission among Q frequency domain repeated transmissions may occupy consecutive frequency domain resources.

In an exemplary embodiment, a single transmission among Q frequency domain repeated transmissions may occupy non-contiguous frequency domain resources.

In an exemplary embodiment, different frequency domain repeated transmissions among the Q frequency domain repeated transmissions may occupy consecutive frequency domain resources.

In an exemplary embodiment, different frequency domain repeated transmissions among the Q frequency domain repeated transmissions may occupy non-contiguous frequency domain resources.

In an exemplary embodiment, the same frequency domain pattern may be occupied in the same slot in Q frequency domain repeated transmissions.

In an exemplary embodiment, different frequency domain patterns may be occupied in the same slot in Q frequency domain repeated transmissions.

In an exemplary embodiment, the frequency domain and/or time domain retransmission parameters may further include a time domain retransmission number K, where K is a positive integer greater than or equal to 1, so that the terminal retransmits the uplink data k×q times to the network device on a time-frequency resource configured by the frequency domain and/or time domain retransmission parameters.

In an exemplary embodiment, the time-domain K-time repeated transmissions may be in consecutive K time slots or consecutive K minislots.

In an exemplary embodiment, the same frequency domain pattern may be occupied at different time slots in Q frequency domain repeated transmissions.

In an exemplary embodiment, different frequency domain patterns may be occupied at different time slots in Q frequency domain repeated transmissions.

In an exemplary embodiment, the signaling may include a first RRC signaling, where the first RRC signaling may carry a first uplink unlicensed configuration parameter (e.g., configured grant configuration), where the first uplink unlicensed configuration parameter may include at least one of the frequency domain repeated transmission number Q (e.g., may be denoted as repQ), a redundancy version of the frequency domain repetition (e.g., may be denoted as repQ-RV, where RV is a shorthand for redundancy version redundancy version), a modulation coding scheme, and a time-frequency resource.

In an exemplary embodiment, the possible signaling includes a second RRC signaling and a first DCI signaling, where the second RRC signaling may carry a second uplink unlicensed configuration parameter, the second uplink unlicensed configuration parameter may at least carry the frequency domain repeated transmission number Q, and the first DCI signaling may carry one of a redundancy version of frequency domain repetition, a modulation coding scheme, a time-frequency resource, and the like, to be used for activating/deactivating uplink unlicensed scheduling.

The uplink grant-free is a non-dynamic scheduling, which means that a base station (e.g., gNB) activates an uplink grant once to a UE, and under the condition that the UE does not receive deactivation, the uplink transmission is performed by always using resources designated by the first uplink grant, and the uplink transmission has two transmission types:

-configure authorization type 1: configuring (IE ConfiguredGrantConfig) by RRC through higher layer signaling, e.g. a first uplink unlicensed configuration parameter carried by the first RRC signaling;

-configure authorization type 2: the activation and deactivation of the indication uplink grant is performed by DCI (e.g. the first DCI signaling described above), and the required parameters are configured by IE ConfiguredGrantConfig (e.g. the second uplink grant-free configuration parameters carried by the second RRC signaling described above), but are used only when the DCI is required to be activated.

Configuration authorization type 1 and type 2 are distinguished according to the field rrc-configurable uplink grant in IE ConfiguredGrantConfig, which is configured for authorization type 1 if the field is configured, and configured for authorization type 2 if the field is not configured.

If the uplink unlicensed configuration type is type 1, parameters in the rrc-configurable uplink grant are all parameters required by type 1, i.e. the first uplink unlicensed configuration parameters may include: time domain resources, frequency domain resources, modulation coding scheme, antenna ports, SRS (Sounding Reference Signal, channel sounding reference signal) resource indication, demodulation reference signal (demodulation reference signal, DM-RS) and other relevant parameters. In addition, IE ConfiguredGrantConfig, i.e. the first uplink unlicensed configuration parameter, also includes common parameters required for type 1 and type 2, such as: all parameters required for uplink transmission, such as period (periodicity), HARQ (Hybrid Automatic Repeat Request), hybrid automatic repeat request) process number (nrofHARQ-process), power control, time domain repetition number (repK), redundancy version of time domain repetition (repK-RV), frequency domain repetition number Q (repQ), redundancy version of frequency domain repetition (repQ-RV), etc.

Meanwhile, as for type 2, it can be seen that, except for the common parameters required by type 1 and type 2, the second uplink unlicensed configuration parameters do not configure related parameters such as time domain resources, frequency domain resources, modulation coding scheme, and the like. As can be seen from the above, the configuration grant type 2 is activated by DCI, so for type 2, when the UE receives the common parameters configured in the rrc-configurable uplink grant and required by type 1 and type 2, uplink transmission will not be immediately performed, and only when the UE receives the DCI indication activated by CS-RNTI (Configured Scheduling-Radio Network Tempory Identity, configuration scheduling-radio network temporary indication) and carries relevant parameters such as time domain resource, frequency domain resource, modulation coding scheme (IMCS), the UE will perform uplink unlicensed transmission of type 2. In the embodiments of the present disclosure, the time domain resource and the frequency domain resource may be collectively referred to as a time-frequency resource.

If the higher layer does not transmit a TB (Transport Block) on the resources allocated by the uplink grant, the UE does not transmit any content on the resources configured by the GrantConfig.

For both configuration grant types, there is a common configuration parameter "periodicity", so once both configuration types are activated, the UE will periodically send uplink data on PUSCH (Physical Uplink Share CHannel, uplink shared physical channel). That is, once the configuration is activated, the UE always performs uplink transmission at the periodic point (unless deactivated), and the DCI is not required to perform indication every time as in the case of dynamically allocating uplink resources, so that the idle transmission time for the UE to transmit SR (Scheduling Request ), BSR (Buffer Status Report, buffer status report) and gNB to perform resource indication through the uplink DCI can be saved, and thus the uplink grant is more suitable for a low-latency scenario.

Repeated transmissions may improve the reliability of the transmission and may bring about gains. The embodiment of the disclosure can support repeated transmission in uplink unlicensed transmission, and the number of repeated transmission is configured by common parameters repK and repQ of type 1 and type 2 in IE ConfiguredGrantConfig. The parameters repK and repK-RV, and repQ-RV in IE ConfiguredGrantConfig define K x Q repetitions of the transmission TB, and redundancy version patterns applied to the repetitions. If there are no configuration parameters repK and repQ in the configurationgrant, the redundancy version of the uplink transmission with configuration grant should be set to 0.

For PUSCH transmissions with configuration grants type 1 and type 2, when the UE configuration parameter repK >1 or repQ >1, the UE should repeatedly send the same TB K x Q times on K x Q transmission occasions.

In an exemplary embodiment, the signaling includes a third RRC signaling and a second DCI signaling, where the third RRC signaling carries a semi-persistent scheduling SPS configuration parameter, the SPS configuration parameter carries the frequency domain repetition transmission number Q, and the second DCI signaling may at least carry one of a redundancy version of frequency domain repetition, a modulation coding scheme, and a time-frequency resource, etc. for activating/deactivating downlink SPS scheduling.

In an exemplary embodiment, the signaling includes a fourth RRC signaling carrying the frequency domain repeated transmission number Q and a third DCI signaling carrying redundancy versions of frequency domain repetition and/or time-frequency resources for activating/deactivating uplink/downlink dynamic grant DG (Dynamic grant) scheduling.

SPS (semi-persistent scheduling ) allows semi-persistent configuration of radio resources and periodically allocates the resources to a particular UE, as opposed to allocating radio resources once per TTI (Transport Time Interval, transmission time interval) for dynamic scheduling (specified by PDCCH (Physical Downlink Control Channel, physical downlink control channel)). The eNB uses the PDCCH scrambled by the SPS C-RNTI to specify radio resources (SPS resources) used by the UE in a certain TTI, and every one period, the UE uses the SPS resources to receive or transmit data, and the eNB does not need to transmit the PDCCH to specify the allocated resources in the subframe (SPS subframe).

According to the method provided by the embodiment of the disclosure, the signaling is sent to the terminal through the network equipment, so that the repeated transmission parameters of the frequency domain and/or the time domain are configured for the terminal through the signaling, and the terminal repeatedly transmits uplink data to the network equipment based on the repeated transmission parameters of the frequency domain and/or the time domain, so that the requirements of high service rate and high reliability can be met.

The 5G evolution technology has been determined to be 5G-Advanced. The 5G-Advanced enhances the uplink capability, broadband real-time interaction, low delay and other capabilities on the 5G basic version. The method provided by the embodiment of the disclosure is a transmission method for 5G-Advanced applicable to high-speed and high-reliability service.

As one of important application scenarios/services in 5G, virtual Reality (VR) and augmented Reality (augmented Reality, AR) will be comprehensively evolved to augmented Reality (XR) in the 5G-Advanced and 6G ages. XR is a new type of business, all real and virtual environments generated by computer graphics and wearable devices.

The method provided by the embodiment of the disclosure can be suitable for various novel services, such as XR (X, Y (Cloud game)), CA (carrier aggregation), a plurality of carriers are aggregated and sent, spectrum resources in the same frequency band or different frequency bands are aggregated and used for UE (user equipment), the speed rate)/DC (Dual connectivity) of the UE is improved, the UE is simultaneously connected with two base stations, and the coverage problem of cell edge users)/CA+DC/spectrum multiplexing is solved.

The uplink CG and the downlink SPS in the existing standard are designed to be used for semi-static configuration transmission of fixed size data, and only support repeated transmission of K slots (slots)/mini-slots (micro slots) in the time domain, so that the requirements of XR service on high transmission rate and high reliability cannot be met at the same time.

Therefore, enhancement is needed for the existing CG/SPS, which is suitable for multiple spectrum resource combinations in the future, and simultaneously meets the requirements of new services in the future for high transmission rate and high reliability.

The scheme provided by the embodiment of the disclosure is a frequency domain repeated transmission method which is oriented to 5G-Advanced and is suitable for various frequency spectrum resources and meets the requirements of high service speed and high reliability.

The base station may configure frequency domain repeated transmission for UE semi-static/dynamic on at least one of the following frequency domain resources through signaling (DCI/MAC CE/RRC signaling, etc.) according to traffic requirements (e.g., high data rate, high reliability, etc)/terminal capability (transmit power)/channel conditions, etc.:

single carrier, for example: active BWP (bandwidth part, active BWP refers to active BWP) and/or initial BWP (initial bandwidth part) for frequency domain retransmission;

multicarrier, in carrier aggregation and/or multiconnection and/or spectrum aggregation, the repetition of transmissions is performed using multiple carriers, for example: frequency domain repeated transmission is carried out on 700/800/900MHz frequency spectrum aggregation.

In the embodiment of the disclosure, the frequency domain repeated transmission may select one of the following schemes:

scheme 1 (frequency domain Q repetition transmission);

Scheme 2 (time domain K-time repeat transmission+frequency domain Q-time repeat transmission).

Wherein:

frequency domain: the frequency domain resources supporting transmission of a single repetition may be contiguous (e.g., the schemes of fig. 2 and 3) or non-contiguous RB (Resource Block) resources (e.g., the scheme of fig. 4); supporting multiple repeated transmissions may be contiguous (e.g., the fig. 2 scheme) or non-contiguous (e.g., the fig. 3 scheme and the fig. 4 scheme) in the frequency domain; multiple repeated transmissions are supported to occupy the same frequency domain pattern or different frequency domain patterns in the same/different slots/mini-slots.

Time domain: is K slots or mini-slots in succession.

For the above scheme 1, fig. 2 to 4 are illustrated, but the present disclosure is not limited thereto.

Taking a single carrier as an example, as shown in fig. 2, it is assumed that one minislot (e.g., t 1) is a mini-slot of 4OFDM (Orthogonal Frequency Division Multiplexing ) symbol (symbol) length, and that q=2, that is, fig. 2 is an example of frequency domain q=2 repeated transmissions (frequency domain continuation) (2 frequency domain repetitions), and the same frequency domain pattern is occupied in the same minislot. Wherein f1 represents frequency domain first repetition transmission, and f2 represents frequency domain second repetition transmission.

Taking a single carrier as an example, as shown in fig. 3, it is assumed that one minislot (e.g., t 1) is a mini-slot with a length of 4OFDM symbols, and q=2 is assumed, that is, fig. 2 is an example of frequency domain q=2 repeated transmissions (frequency domain non-consecutive), and different frequency domain patterns are occupied in the same minislot. Wherein f1 represents frequency domain first repetition transmission, and f2 represents frequency domain second repetition transmission.

Taking a single carrier as an example, as shown in fig. 4, it is assumed that one minislot (e.g., t 1) is a mini-slot with a length of 4OFDM symbols, and q=2 is assumed, that is, fig. 2 is an example of frequency domain q=2 repeated transmissions (frequency domain non-consecutive), and the same frequency domain pattern is occupied in different minislots. Wherein f1 represents frequency domain first repetition transmission, and f2 represents frequency domain second repetition transmission.

Scheme 2 is illustrated in fig. 5, but the disclosure is not limited thereto.

As shown in fig. 5, assume one minislot (e.g., t1, t2, t3, t 4) is a mini-slot of 4OFDM symbol length, and assume k=4, q=2, i.e., fig. 5 is an example of time domain k=4, frequency domain q=2 repeated transmissions (frequency domain consecutive), and occupy the same frequency domain pattern in different minislots and the same minislot.

In the embodiment of fig. 5, at t3, since the 2 nd OFDM symbol is at the slot boundary (slot boundary), the remaining repeated transmission can only use 2 OFDM symbols, and another 2 OFDM symbols are used for the other half of the transmission after crossing the slot boundary instead of using 4OFDM symbols. I.e. when one repetition needs to be transmitted across slot boundaries, it is split into two repeated PUSCH transmissions, and the multiple PUSCH repetitions do not share DM-RS, e.g. the same or different redundancy versions may also be used.

There is no specific method for frequency domain repeated transmission applicable to various frequency resources based on NR.

According to the method provided by the embodiment of the disclosure, on one hand, the base station performs frequency domain repeated transmission on single-carrier or multi-carrier available frequency domain resources for UE semi-static/dynamic through signaling according to service requirements (such as high data rate, high reliability and the like)/terminal capability (transmitting power)/channel condition and the like, so that different frequency spectrum resources of LTE/5G/5G-Advanced can be fully utilized, and the reliability requirements of high-rate service can be better ensured according to different terminal capability and channel condition.

For example: UE services have a need for high data rates, and the terminal capability can support configuring multi-carrier frequency domain repeated transmission for the UE through signaling when transmitting on multiple frequency bands simultaneously.

For example: the UE has a need for high data rate and high reliability, and the terminal capability supports high power transmission, and when the terminal capability can only support simultaneous data transmission on one frequency band, single carrier frequency domain repeated transmission is configured for the UE through signaling.

For example: when the channel condition of the UE is poor, the terminal capability support is transmitted on a plurality of frequency bands simultaneously, the multi-carrier frequency domain repeated transmission is configured for the UE through signaling.

On the other hand, the method provided by the embodiment of the disclosure supports multiple frequency domain repeated transmission schemes, and the frequency domain resource supporting transmission of a single repetition can be continuous or discontinuous RB resource; supporting multiple repeated transmissions may be contiguous or non-contiguous in the frequency domain; the method supports that a plurality of repeated transmissions occupy the same frequency domain pattern or different frequency domain patterns in the same/different slots/mini-slots, can be better suitable for different spectrum resource aggregation conditions through a flexible frequency domain configuration scheme, and can realize frequency domain repeated transmission through a plurality of signaling configurations of RRC/MAC CE/DCI.

For example: an operator can configure a single frequency band of 800MHz or 900MHz for the customer served by the operator to perform frequency domain retransmission, or perform frequency domain retransmission on the 800MHz and 900MHz simultaneously.

For example: three operators share the same building on 700MHz, different frequency domain repeated resource configurations can be configured according to the user priority or different service priorities, the high priority service/high priority user transmits more frequency domain repeated transmission resources, and discontinuous RB resources can be considered during configuration, and different frequency domain resources can be adopted on different time slots.

For example: on a frequency band with stronger frequency selectivity or wider channel condition, configuring single repeated frequency domain resources as discontinuous RB resources so as to obtain more frequency selectivity gain.

For example: configuring multiple repeated transmissions over a frequency band that is more frequency selective or wide for channel conditions or over multiple available frequency bands may be discontinuous in the frequency domain, allowing more frequency selective gain and scheduling flexibility.

For another example, when different frequency bands have different traffic loads, different time slots can be configured to use different frequency domain patterns according to traffic load conditions so as to adapt to the traffic load conditions of different frequency bands/different times, and more scheduling flexibility is provided.

In addition, the method provided by the embodiment of the disclosure is particularly suitable for uplink unlicensed CG scheduling, downlink semi-persistent SPS scheduling, and can be used for uplink and downlink dynamic licensed DG scheduling and other various resource allocation modes, thereby providing high reliability for high data rate services.

The embodiment of the disclosure provides a frequency domain repeated transmission scheme suitable for 5G-Advanced high data rate high reliability service, and the frequency domain repeated transmission resources for aggregating different frequency domain resources are configured for a terminal through signaling semi-static/dynamic so as to meet the requirements of the service on high data rate and high reliability.

The following is illustrative by way of specific examples.

The method provided by the embodiment of the disclosure can comprise the following steps.

Step 1: the base station configures frequency domain repeated transmission times Q and time domain repeated transmission times K for UE semi-static/dynamic on at least one of the following frequency domain resources through signaling (DCI/MAC CE/RRC signaling and the like) according to service requirements (such as high data rate, high reliability and the like)/terminal capability (transmitting power)/channel condition and the like, wherein the repeated transmission times of the UE for transmitting data on the configured time-frequency resources are K times Q times:

for example: single carrier, for example: and carrying out frequency domain repeated transmission on the active BWP.

For example: in carrier aggregation and/or multi-connection and/or frequency aggregation, multiple carriers are used for repeated transmission, for example: frequency domain repeated transmission is carried out on 700/800/900M frequency spectrum aggregation.

Step 2: the frequency domain Q times of repeated transmission at least supports one of the following:

(2.1) the frequency domain resources supporting transmission of a single repetition may be contiguous (e.g., the fig. 2 scheme and the fig. 3 scheme) and non-contiguous RB resources (e.g., the fig. 4 scheme).

For example: the single repetition occupies frequency domain resources as PRBs 0-15 or, to obtain a frequency selective gain, the single repetition occupies non-contiguous frequency resources PRBs 0-7, PRBs 40-47. One RB on one slot is called a Physical RB (PRB).

(2.2) supporting multiple repeated transmissions may be contiguous (e.g., the fig. 2 scheme) or non-contiguous (e.g., the fig. 3 scheme and the fig. 4 scheme) in the frequency domain.

For example: the frequency domain repeat transmission times q=2, the 1 st transmission occupies frequency domain resources PRB0-15, and the 2 nd transmission occupies frequency domain resources PRB16-31 consecutive to the 1 st transmission.

For example: the frequency domain repeat transmission times q=2, the 1 st transmission occupies frequency domain resources PRB0-15, and the 2 nd transmission occupies frequency domain resources PRB100-115 discontinuous with the 1 st transmission.

(2.3) supporting multiple repeated transmissions occupying the same frequency domain pattern or different frequency domain patterns at the same/different slots/mini-slots.

For example: the frequency domain repeated transmission times Q=2 and the time domain repeated transmission times K=2, and in the first slot, the 1 st transmission occupies frequency domain resources PRB0-7 and PRB64-71; in the first slot, the 2 nd transmission occupies the frequency domain resources PRB72-87.

Step 3: the time domain supports K slots or mini-slots with continuous time domain for repeated transmission.

Embodiment 1 is illustrated by way of example of an uplink grant enhancement applied to an uplink grant-free schedule.

Type 1: the RRC (e.g., the first RRC signaling) configures the frequency domain retransmission number Q and parameter configurations corresponding to the frequency domain repetition, e.g.: redundancy version of frequency domain repetition, modulation coding mode/time-frequency resource, etc., and adding cell indication such as repQ, repQ-RV, etc. in the first uplink unlicensed configuration parameter configuration GrantConfig.

For example: the RRC time-frequency resource allocation supports allocation over multiple frequency bands, and may be repeated for single or dual cycles.

The uplink unlicensed scheduling is to configure a time-frequency resource for uplink transmission, and then configure a period of use of the time-frequency resource, for example, a section of frequency domain resource of the 3 rd slot may be used for transmission every 5 ms.

Single period repeated transmission means that the repeated transmission configuration adopted by each unlicensed uplink data transmission is the same.

Dual cycle/multicycle repeat transmission refers to, for example: the current CG resource uses one set of frequency domain repeated transmission configuration q=4, and the CG resource of the next period uses another set of frequency domain repeated transmission configuration q=2, which alternately appear.
