Abstract

The transmission method of the embodiment of the application comprises the following steps: a terminal receives first indication information, wherein the first indication information is used for indicating a sending or receiving behavior of a first time domain resource, the first time domain resource comprises at least one time domain unit in a second time domain resource, the second time domain resource is an unoccupied time domain resource in first uplink transmission, and the sending or receiving behavior is not performed on the second time domain resource; and the terminal sends the first uplink transmission or stops the first uplink transmission.

Description

Transmission method and device

Technical Field

The present application belongs to the field of communications technologies, and in particular, to a transmission method and device.

Background

The terminal may keep consistent power and continuous phase in the transmission process of multiple Uplink channels, where the Uplink channels may be a Physical Uplink Shared Channel (PUSCH), a Physical Uplink Control Channel (PUCCH), and the like. In this way, when the network side device receives the multiple uplink channels, joint channel estimation may be performed by using Demodulation Reference signals (DMRSs) in the multiple uplink channels to improve reception performance, and this technique may be referred to as DMRS bonding (bundling).

Non-back-to-back (non-back-to-back) transmission refers to transmission in which the plurality of uplink channels perform uplink repeat transmission of the same Transport Block (TB) on adjacent time slots, but do not occupy the entire time slot. There are some unoccupied symbols in the middle of adjacent transmissions, which are called gaps (gaps). The symbols in the gap may be scheduled by the network side device to perform some uplink and downlink transmissions, such as sending of uplink Sounding Reference Signal (SRS) or downlink PDCCH monitoring. When DMRS-bonded transmissions are performed, the terminal also needs to maintain uniform power and/or continuous phase on these symbols, and therefore the terminal does not expect to transmit or receive on these unoccupied symbols.

If the terminal receives the indication information, the indication information changes the sending or receiving behavior on the unoccupied symbol, and the terminal cannot keep consistent power and continuous phase transmission any more, at this time, the terminal may not be able to determine how to perform transmission (e.g., sending), and the network side device may also not be able to determine how to perform transmission (e.g., receiving), which affects the communication effectiveness.

Fig. 1 shows a schematic diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes a terminal 11 and a network-side device 12. Wherein, the terminal 11 may also be called a terminal Device or a User Equipment (UE), the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer) or a notebook Computer, a Personal Digital Assistant (PDA), a palmtop Computer, a netbook, a super-Mobile Personal Computer (UMPC), a Mobile Internet Device (Mobile Internet Device, MID), an augmented reality (augmented reality, AR)/Virtual Reality (VR) Device, a robot, a Wearable Device (Wearable Device), a vehicle mounted Device (VUE), a pedestrian terminal (PUE), a smart home (a Device with wireless communication function, such as a refrigerator, a television, a washing machine or furniture), and the like, and the Wearable Device includes: smart watch, smart bracelet, smart earphone, smart glasses, smart jewelry (smart bracelet, smart ring, smart necklace, smart anklet, etc.), smart wristband, smart garment, game console, etc. It should be noted that the embodiment of the present application does not limit the specific type of the terminal 11.

The transmission method and device provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings by using some embodiments and application scenarios thereof.

The non-back-to-back (non-back-to-back) transmission mentioned in the embodiments of the present application may be an uplink transmission in an adjacent timeslot and not occupying the entire timeslot, or may be a transmission structure of a PUXCH repeat (repetition)/transmission (transmission) + gap (gap) + PUXCH repetition/transmission, so that the non-back-to-back transmission includes transmission of a PUXCH repetition or PUSCH transmission, and transmission of a PUXCH repetition/transmission + gap + PUXCH repetition/transmission, where the gap refers to an unoccupied symbol, may also be described as the number of symbols that the terminal does not transmit, or the number of symbols that the terminal does not expect to be scheduled by the network side device, and needs to be less than a certain threshold, for example, 13symbols.

DMRS bundled transmission may be performed in non-back-to-back transmission, but the terminal still needs to keep a Power Amplifier (PA) on in the middle gap (gap) to ensure phase continuity. This means that even if the terminal does not transmit signals within this gap, it will still generate power radiation, which will affect the performance of other transmissions made within the gap.

In NR, signaling cancellation on part of the symbols is supported by dynamic indication information, which is typically signaled to preferentially guarantee the performance of other users for transmission. Then, the network side device may instruct the terminal not to signal in the gap through the dynamic indication information, including instructing the terminal to avoid generating a large radiated power without signaling.

If the terminal receives an indication that at least one symbol in the gap should avoid signal radiation, then on that symbol the terminal still needs to meet an off-power requirement (typically turning the PA off), the transmission conditions for phase continuity will no longer be met and the terminal may not be able to determine how to transmit.

The embodiment of the present application may indicate a terminal behavior, for example, a behavior that restricts the terminal from performing DMRS binding transmission, and generate a new binding manner through configuration or indication, and maintain consistent power and continuous phase transmission in a new time domain window (time domain window), where the new time domain window may be referred to as an actual time domain window.

As shown in fig. 2, the present embodiment provides a transmission method 200, which may be performed by a terminal, in other words, by software or hardware installed in the terminal, and includes the following steps.

S202: the terminal receives first indication information, wherein the first indication information is used for indicating a sending or receiving behavior of a first time domain resource, the first time domain resource comprises at least one time domain unit in a second time domain resource, the second time domain resource is an unoccupied time domain resource in first uplink transmission, and the sending or receiving behavior is not performed on the second time domain resource.

In this embodiment, the first Uplink transmission may include one or more Physical Uplink Shared Channel (PUSCH) transmissions, and may also include one or more Physical Uplink Control Channel (PUCCH) transmissions, and the like, and the Uplink transmission in the subsequent embodiment mostly represents the one or more Physical Uplink transmission channels by taking PUXCH as an example. . In one example, the first uplink transmission is a non-back-to-back (non-back-to-back) transmission.

The first uplink transmission includes an unoccupied time domain resource, that is, a second time domain resource, where the second time domain resource may be referred to as a gap (gap), the second time domain resource may include one or more symbols, generally not more than 13symbols, and no transmission or reception is performed on the second time domain resource.

Under the condition that the first indication information is not received, the terminal can maintain consistent power and continuously send the first uplink transmission in phase, so that the network side equipment can perform Joint channel estimation (Joint channel estimation) on the first uplink transmission, and the receiving performance is improved. The joint channel estimation refers to a mode that a plurality of continuous slots (slots) in a plurality of PUXCHs capable of keeping consistent power (or called consistent power) and continuous phases are jointly used for channel estimation, the network side equipment performs joint channel estimation from the perspective of the network side equipment, the terminal side performs transmission for keeping consistent power and continuous phases in a predefined or preconfigured time domain window on the continuous slots of the plurality of PUXCHs, and the terminal and the network side equipment use the same enabling signaling to open or close the configured time domain window, for example, the enabling signaling is designed as PUCCH-TimeDonWindow-r 17, PUSCH-TimeDonWindow-r 17 and the like.

The configured time domain window may be configured by Radio Resource Control (RRC) in 1 or more, and one configured time domain window may include multiple consecutive physical slots (slots) or physical symbols (symbols). The length of the configured time domain window can be configured to a specific value L that cannot exceed a threshold and cannot exceed the maximum capability of the terminal (e.g., maximum duration) that can maintain phase consistency. L may be configured per terminal portion BandWidth (BWP), for example in PUSCH-config or PUCCH-config, but is not excluded to be configured otherwise, for example in PUCCH-resource in PUCCH-config in per resource configuration information form, or in PUCCH-format0, PUCCH-format1, PUCCH-format2, PUCCH-format3, PUCCH-format4 in PUCCH-config in per format configuration information form.

It should be noted that, the time domain window introduced in the subsequent embodiments of the present application, such as the actual time domain window, may be a part of the configured time domain window described above, and when the terminal sends the first uplink transmission in the time domain window, the power may be kept consistent and/or the phase may be kept continuous; the network side device may perform joint channel estimation on the first uplink transmission in the time domain window.

In this embodiment, the terminal may receive the first indication information before sending the first uplink transmission, or may also receive the first indication information during the first uplink transmission, where the first indication information is used to indicate a sending or receiving behavior of the first time domain resource.

The first time domain resource includes at least one time domain unit in the second time domain resource, and the unit of the time domain unit can be a symbol. The size of the first time domain resource and the second time domain resource is not limited in this embodiment, as long as there is an intersection between the two, which is the aforementioned at least one time domain unit. For example, in the case that the second time domain resource is the 9 th to 14 th symbols of the time slot 1, the first time domain resource may be the 9 th to 14 th symbols of the time slot 1, that is, the first time domain resource and the second time domain resource are the same; or, the first time domain resource may be the 10 th to 13 th symbols of the slot 1, that is, the range of the first time domain resource is smaller than the second time domain resource; or the first time domain resource comprises the 9 th to 14 th symbols of the time slot 1 and also comprises the 9 th to 14 th symbols of the time slot 2, and the range of the first time domain resource is larger than that of the second time domain resource.

As mentioned above, the first indication information is used to indicate a transmission or reception behavior of the first time domain resource, where the first time domain resource includes at least one time domain unit in the second time domain resource, and the second time domain resource needs to remain without transmission or reception behavior, that is, a transmission property of the at least one time domain unit may change.

For example, the first indication information indicates that the type of the first time domain resource is flexible or downlink, or the first indication information indicates that the terminal cancels transmission on the first time domain resource, or the first indication information indicates that the first time domain resource is unavailable, and in these cases, the terminal cannot maintain consistent power and continuous phase transmission.

S204: and the terminal sends the first uplink transmission or stops the first uplink transmission.

In this embodiment, the terminal may send the first uplink transmission by using the first processing method, and the first processing method may have multiple implementation manners, for example, transmission without maintaining phase continuity is performed, that is, the terminal does not maintain original power consistency and phase continuity transmission, and for example, the first uplink transmission is transmitted according to a default rule according to the terminal and the network side device.

In the transmission method provided by the embodiment of the present application, a terminal receives first indication information, where the first indication information is used to indicate a sending or receiving behavior of a first time domain resource, the first time domain resource includes at least one time domain unit in a second time domain resource, the second time domain resource is an unoccupied time domain resource in first uplink transmission, and the sending or receiving behavior is not performed on the second time domain resource.

Optionally, the sending, by the terminal in embodiment 200, the first uplink transmission includes: the terminal sends the first uplink transmission by using a first processing method, where the first processing method may include one of:

1) Transmission without maintaining phase continuity is performed. In this way, the terminal will no longer maintain consistent power and continuous phase transmission, and accordingly, the network side device may no longer perform joint channel estimation on the first uplink transmission.

2) And adjusting transmission according to the content indicated by the first indication information. The first uplink transmission may be located in a configured time domain window, and the first indication information may indicate an actual time domain window, so that the terminal may maintain consistent power and continuous phase transmission in the actual time domain window. The actual time domain window may be a part of the configured time domain window, and whether the actual time domain window may be formed after the first time domain resource or the second time domain resource depends on the capability of the terminal, in addition to the specific window information indicated by the first indication information, that is, whether the terminal can still maintain the power consistency and the phase continuity after the first time domain resource or the second time domain resource.

3) And transmitting according to a default rule, wherein the default rule is used for determining a time domain window, and the time domain window is used for sending the first uplink transmission. The first uplink transmission may be located in a configured time domain window, and the default rule includes, for example: the configured time domain window is divided into a plurality of actual time domain windows, so that the terminal can keep consistent power and continuous phase transmission in the actual time domain windows. Whether the actual time domain window can be formed after the first time domain resource or the second time domain resource depends on the capability of the terminal, i.e. whether the terminal can maintain consistent power and continuous phase after the first time domain resource or the second time domain resource, in addition to the default transmission rule.

4) The transmission is performed within a range of the first index. For example, the first indicator includes a phase continuity tolerance that represents a maximum phase discontinuity that can be tolerated when performing the joint channel estimation.

First uplink transmission in an example, the first processing method is the adjusting transmission according to the content indicated by the first indication information in 2), where the first indication information further includes at least one of the following:

a) And the position information of the time domain window is used for determining the position of the time domain window by the terminal or the network side equipment. In this example, the terminal maintains the first characteristic transmission within a determined time domain window (i.e., an actual time domain window), which does not include the second time domain resource or the first time domain resource. In one example, the same power may be possessed in two time domain windows before and after the first time domain resource or the second time domain resource, and the phase may be continuous, and the respective power consistency and phase continuity characteristics may be maintained in the two time domain windows. Let the time domain window length be L, the position information of the time domain window indicated by it may be the position information of the group from the nth physical slot/OFDM symbol, to the (n + L-1) th physical slot/OFDM symbol, or the nth available slot/OFDM symbol, to the (n + L-1) th available slot/OFDM symbol. Optionally, the first feature comprises: power uniformity and/or phase continuity.

b) And the size (or called length) information of the time domain window is used for the terminal or the network side equipment to determine the size and the position of the time domain window. In this example, the terminal maintains the first characteristic transmission in a determined time domain window (i.e., an actual time domain window), which does not include the second time domain resource or the first time domain resource. In one example, the two time domain windows before and after the first time domain resource or the second time domain resource may have the same power and may be phase-continuous, and the two time domain windows may respectively maintain their respective power consistency and phase continuity characteristics, and the length of the time domain window does not exceed the maximum configurable time domain window length and does not exceed the maximum sustainable time for the terminal to maintain phase continuity. The process of determining the time domain window by the combination of the indicated window size and the position information may be to calculate a next physical slot/symbol length L, or calculate a next available slot/symbol length L, as the position information of the time domain window, with reference to a first physical slot/OFDM symbol of the first PUXCH, or a first physical slot/OFDM symbol available to the first PUXCH, or calculate a next physical slot/symbol length L, or calculate a next available slot/symbol length L, as the position information of the time domain window, with reference to a reference position slot or reference position symbol which may be included in the first indication information, or a reference position symbol, as the position information of the time domain window. Optionally, the first feature comprises: power uniformity and/or phase continuity.

c) And the starting information of the time domain window is used for the terminal or the network side equipment to determine the starting position of the time domain window. In this example, the terminal maintains the first characteristic transmission within a determined time domain window (i.e., an actual time domain window), which does not include the second time domain resource or the first time domain resource. In one example, the two time domain windows before and after the first time domain resource or the second time domain resource may have the same power, may be capable of being phase-continuous, and may also maintain respective power consistency and phase continuity characteristics in the two time domain windows. The start information is, for a first time domain window in the first uplink transmission, a first starting PUXCH, and may be a first physical slot or a physical OFDM symbol, or a first available slot or an available OFDM symbol of the PUXCH. And for the start information of other positions, the start information indicated by the first indication information is used. Optionally, the first feature comprises: consistent power and/or continuous phase.

d) And the termination information of the time domain window is used for determining the termination position of the time domain window by the terminal or the network side equipment. In this example, the terminal maintains the first characteristic transmission within a determined time domain window (i.e., an actual time domain window), which does not include the second time domain resource or the first time domain resource. In one example, the two time domain windows before and after the first time domain resource or the second time domain resource may have the same power, may be capable of being phase-continuous, and may also maintain respective power consistency and phase continuity characteristics in the two time domain windows. The termination information is the last physical slot or physical OFDM symbol, or the last available slot or available OFDM symbol for the last PUXCH transmission. And for the termination information of other positions, the termination information indicated by the first indication information is used. It is noted that the time domain window is automatically terminated when the PUXCH transmission reaches the maximum capability of the terminal to maintain consistent power and phase continuity. Optionally, the first feature comprises: power uniformity and/or phase continuity.

For example, for a configured time domain window, the terminal determines a first actual time domain window based on the termination information of the time domain window, and the starting time of the first actual time domain window is the same as the configured time domain window; the terminal determines a second actual time domain window based on the termination information of the time domain window, the termination time of the second actual time domain window is the same as the configured time domain window, the embodiment can realize that the configured time domain window is divided into two actual time domain windows, the terminal can keep the respective power consistent and the phase continuous transmission in the two actual time domain windows, the two actual time domain windows also can have the same power and can have continuous phases, and the two conditions both enable the network side equipment to carry out joint channel estimation and improve the receiving performance.

In one example, the first processing method is the default rule in 3) including at least one of:

1) Position information of a predefined or preconfigured time domain window. And the position information of the time domain window is used for the terminal or the network side equipment to determine the position of the time domain window. In this example, the terminal maintains the first characteristic transmission within a determined time domain window (i.e., an actual time domain window), which does not include the second time domain resource or the first time domain resource. Let the time domain window length be L, its predefined or preconfigured window position information may be the position information of the group of slots/symbols from the nth physical slot/OFDM symbol, to the n + L-1 th physical slot/OFDM symbol, or the nth available slot/OFDM symbol, to the n + L-1 th available slot/OFDM symbol. Since the time domain window may be one or more, the preconfigured or predefined location information may be one or more sets. Optionally, the first feature comprises: consistent power and/or continuous phase.

2) Size (or length) information of a predefined or preconfigured time domain window. And the size information of the time domain window is used for the terminal or the network side equipment to determine the size and the position of the time domain window. In this example, the terminal maintains the first characteristic transmission in a determined time domain window (i.e., an actual time domain window), which does not include the second time domain resource or the first time domain resource. Let the time domain window length be L, and its predefined or preconfigured window length may be one or more unequal lengths. The time domain window length is configured to not exceed a maximum length Lmax. For one or more configured time domain window lengths, which are larger than the maximum capability of the terminal capable of maintaining phase continuity transmission, the actual time domain window length is based on the maximum capability of the terminal capable of maintaining phase continuity transmission. Optionally, the first feature comprises: power uniformity and/or phase continuity.

3) Periodic information of a predefined or preconfigured time domain window. And the period information of the time domain window is used for the terminal or the network side equipment to determine the size and the position of the time domain window. In this example, the terminal maintains the first characteristic transmission in a determined time domain window (i.e., an actual time domain window), which does not include the second time domain resource or the first time domain resource. Optionally, the first feature comprises: power uniformity and/or phase continuity.

4) Segmentation rule information of a predefined or preconfigured time domain window. And the division rule information of the time domain window is used for the terminal or the network side equipment to divide the configured time domain window so as to obtain the actual time domain window. In this example, the terminal may further maintain the first characteristic transmission in an actual time domain window, where the actual time domain window does not include the second time domain resource or does not include the first time domain resource. The start information of the segmentation information is, for a first time domain window in the first uplink transmission, a first start PUXCH, which may be a first physical slot or a physical OFDM symbol, or a first available slot or an available OFDM symbol of the PUXCH; for the start information of other locations, the implicit determination will be made using RRC configured information or using predefined rules. For example, the predefined first indication information is an event and is an implicit indication that the starting positions of other time domain windows will be started according to the first physical slot/symbol or the first available slot/symbol closest to the first resource indicated by the first indication information or the second resource containing the first resource. The termination information of the segmentation information is, for the last PUXCH transmission, the last physical slot or physical OFDM symbol thereof, or the last available slot or available OFDM symbol. For the termination information of other locations, the implicit determination will be made using RRC configured information or using predefined rules. For example, if the first indication information is predefined as an event and is an implicit indication, the termination position of the other time domain window will be terminated according to the last physical slot/symbol or the last available slot/symbol closest to the first resource indicated by the first indication information or the second resource including the first resource. In addition, if the window length reaches the maximum capability of the terminal to maintain phase continuity transmission, it is automatically terminated. Optionally, the first feature comprises: power uniformity and/or phase continuity.

5) Frequency hopping rule information within a predefined or preconfigured time domain window. The frequency hopping rule information of the time domain window is used for the terminal or the network side equipment to execute frequency hopping transmission, an actual time domain window can be formed after frequency hopping, the terminal can also keep first characteristic transmission in the actual time domain window, and the actual time domain window does not include the second time domain resource or the first time domain resource. The frequency hopping start information is, for a first time domain window in the first uplink transmission, a first starting PUXCH, and may be a first physical slot or a physical OFDM symbol, or a first available slot or an available OFDM symbol of the PUXCH; for the frequency hopping start information of other locations, the implicit determination will be made using RRC configured information or using predefined rules. For example, RRC pre-configures location information of frequency hopping, or pre-defines the first indication information as an event, which is an implicit indication that the starting location of frequency hopping will be started according to the first physical slot/symbol or the first available slot/symbol closest to the first resource indicated by the first indication information or the second resource containing the first resource. The frequency hopping termination information is, for the last PUXCH transmission, the last physical slot or physical OFDM symbol, or the last available slot or available OFDM symbol. For the termination information of other location hopping, the implicit determination will be made using the information of RRC configuration or using a predefined rule. For example, the RRC pre-configures location information of frequency hopping, or pre-defines the first indication information as an event, which is an implicit indication that the termination location of frequency hopping will be terminated according to the last physical slot/symbol or the last available slot/symbol before the first resource indicated by the first indication information or before the second resource containing the first resource. Furthermore, the hopping is automatically terminated if the window length reaches the maximum capability of the terminal to maintain phase continuity transmission. Optionally, the first feature comprises: power uniformity and/or phase continuity.

6) Predefined or preconfigured power-off requirement information. Optionally, the power-off requirement information instructs the terminal to perform power-off and power-on operations in the second time domain resource, so that the terminal maintains consistent power and/or continuous phase before power-off and after power-on. Or, the power-off requirement information indicates that the terminal turns off some devices, so that the power variation of the terminal is within the range of the power variation tolerance, and the first uplink transmission can maintain phase continuity as much as possible, so that the network side device can still perform joint channel estimation on the first uplink transmission.

In the foregoing embodiments, since a certain event (e.g., an event that triggers the network side device to send the first indication information) breaks the originally configured time domain window and the newly generated time domain window may be referred to as an actual TDM, there may be one or more actual TDM time domain windows, for example, in the subsequent embodiments, the configured time domain window is configured as a configured time domain window, and the actual time domain window is considered as an actual time domain window. These actual time domain windows may be indicated implicitly (e.g., by the default rules introduced above) or may be indicated by the first indication information, and the first actual time domain window is considered as the first PUXCH in the initially configured TDM, which may be the first available or physical slot or the first available or physical symbol of the PUXCH.

Once an actual time domain window starts, its termination depends on several possibilities: a) The last PUXCH transmission from the actual time domain window to the initially configured time domain window is automatically terminated, and the last PUXCH transmission can be the last available or physical time slot or the last available or physical symbol of the actual time domain window; b) This actual time domain window reaches the maximum duration (maximum duration), i.e. the terminal can maintain the maximum capability of phase continuity transmission, and terminates automatically; c) Some events (events) occur, such as a high priority transmission colliding with the current, a need for precoding cycling (precoding cycling), etc.

The end of the actual time domain window in c) is the last available or physical slot, or the last available or physical symbol, of the PUXCH transmission before the event occurred. Whether a new actual time domain window can be formed after an event depends on the terminal capability, if the terminal can still keep phase consistency transmission after receiving an event due to no corresponding capability, the phase consistency transmission is terminated, that is, no corresponding actual time domain window is generated.

Optionally, the first indication information mentioned in the embodiments of the present application may include one of the following:

1) A Slot Format Indicator (SFI) information, where the SFI information is used to indicate that the type of the first time domain resource is flexible or downlink, the first time domain resource may include one or more symbols, and the SFI information is used to indicate that the one or more symbols are flexible symbols or downlink symbols. In case the first indication information indicates a downlink symbol, there may be no actual downlink transmission on the downlink symbol.

2) And Cancel Indication (CI) information, where the CI information is used to indicate the terminal to cancel transmission on the first time domain resource, for example, the CI information indicates that the terminal needs to turn off the PA on at least one symbol of the second time domain resource (gap), and the terminal cannot keep the power consistent any more, and thus cannot ensure phase continuity of the first uplink transmission.

3) Dynamic signaling indicating that the first time domain resources are unavailable.

Optionally, the first uplink transmission mentioned in the embodiments of the present application satisfies at least one of the following conditions:

1) And two ends of the second time domain resource are uplink repeated transmission of the same scheduled Transport Block (TB) or uplink transmission of different TBs. In this embodiment, two ends of the second time domain resource are outside the second time domain resource, and therefore, two ends of the second time domain resource may also be referred to as front and back of the second time domain resource.

In one example, the PUSCHs contained within the configured time domain window may be from the same TB, i.e. a repetition (repetition) form. For example, this embodiment may be applied in an application scenario of the same TB where PUSCH type a (type a) and type B (type B) are repeated. In one example, the PUSCH's included within the configured time domain window may be from different TBs, a form of normal transmission. For example, this embodiment may be applied in application scenarios of different TBs.

2) The length of the second time domain resource is less than a first threshold, which may be specified by a protocol or pre-configured by a higher layer. In one example, the first threshold may be derived from a maximum duration.

The PUXCH mentioned in the embodiments of the present application may be a PUSCH or a PUCCH. For the PUCCH, the scheduling mechanism is the same as that of the PUSCH, but the configuration modes may be different, and besides the possibility that each BWP is configured in the PUCCH configuration, the PUCCH also has the possibility of being configured in PUCCH resources or PUCCH formats, and the configuration in PUCCH resources may facilitate scheduling, and the configuration in PUCCH formats may facilitate combining with frequency hopping.

Example one

As shown in fig. 4, when maintaining phase continuity transmission, the terminal may receive an SFI or CI indication (i.e., first indication information) issued by the network side device, so that transmission properties of symbols or slots (slots) in a gap (gap) are changed or transmission is cancelled, resulting in a change in PA of the terminal and failing to maintain consistent power.

At this time, the terminal may form an actual time domain window during transmission according to time domain window position information, time domain window size information, time domain window period information, or time domain window splitting rule information, etc. pre-configured by the network, and continue to perform respective phase continuity transmission.
