cross reference

The present invention claims the priority of a Chinese patent application filed with the China Patent Office on September 14, 2021, with the application number 202111076934.X and the title of the invention "Transmission method and device", the entire content of which is incorporated by reference in this application middle.

technical field

The present application belongs to the technical field of communication, and specifically relates to a transmission method and equipment.

Background technique

The terminal can maintain consistent power and continuous phase during the transmission of multiple uplink channels. The uplink channel can be a Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH), a Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH), etc. In this way, when the network side device receives these multiple uplink channels, it can use the demodulation reference signal (Demodulation Reference Signal, DMRS) in these multiple uplink channels to perform joint channel estimation to improve the receiving performance. This technology can be called DMRS binding (bundling).

Non-back-to-back (non-back-to-back) transmission means that the above multiple uplink channels perform uplink repeated transmission of the same transport block (TransportBlock, TB) in adjacent time slots, but do not occupy the entire time slot. There will be some unoccupied symbols between adjacent transmissions, these symbols are called gaps. The symbols in the gap may be scheduled by the network side device for some uplink and downlink transmissions, such as sending uplink Sounding Reference Signal (SRS) or downlink PDCCH monitoring. When performing DMRS bundled transmission, the terminal also needs to maintain consistent power and/or phase continuity on these symbols, so the terminal does not expect to perform transmission or reception on these unoccupied symbols.

If the terminal receives the indication information, the indication information changes the sending or receiving behavior on the above-mentioned unoccupied symbols, and the terminal will no longer be able to maintain consistent power and phase continuous transmission. At this time, the terminal may not be able to determine how to perform transmission (such as sending ), the network side device may not be able to determine how to transmit (such as receive), which affects the effectiveness of communication.

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

The non-back-to-back (non-back-to-back) transmission mentioned in various embodiments of this application can be either an uplink transmission in an adjacent time slot and does not occupy the entire time slot, or a PUXCH repetition (repetition)/transmission (transmission)+interval (gap)+PUXCH repetition/transmission transmission structure, therefore, non-back-to-back transmission includes the transmission of PUXCH repetition or PUSCH transmission, and the transmission of PUXCH repetition/transmission+gap+PUXCH repetition/transmission Transmission, where gap refers to unoccupied symbols, which can 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, which needs to be less than a certain threshold, such as 13symbols.

DMRS bonding transmission can be performed in non-back-to-back transmission, but the terminal still needs to keep the power amplifier (Power Amplifier, PA) turned on in the intermediate interval (gap) to ensure phase continuity. And this also means that even if the terminal does not send signals in this gap, it will still generate power radiation, which will affect the performance of other transmissions in this gap.

In NR, it is supported to use dynamic indication information to indicate the cancellation of signal transmission on some symbols. Usually, the cancellation of signal transmission is to ensure the transmission performance of other users first. Then, the network side device may instruct the terminal not to send signals in the gap through dynamic indication information, including instructing the terminal to avoid generating large radiation power in the case of not sending signals.

If the terminal receives indication information indicating that at least one symbol in the gap should avoid signal radiation, then on this symbol, the terminal still needs to meet the off-power requirement (off-power requirement), and the implementation usually turns off the PA, then it will not Even if the transmission condition of phase continuity is met, the terminal may not be able to determine how to transmit.

The embodiment of this application can indicate the behavior of the terminal, for example, restrict the behavior of the terminal to perform DMRS binding transmission, generate a new binding mode through configuration or indication, and maintain power consistency and phase in the new time domain window (time domain window) Continuous transmission, etc., the new time domain window may be called the actual time domain window.

As shown in FIG. 2 , the embodiment of the present application provides a transmission method 200, which can be executed by a terminal, in other words, the method can be executed by software or hardware installed in the terminal, and the method includes the following steps.

S202: The 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, where the first time domain resource includes at least one time domain unit in the second time domain resource, The second time domain resource is a time domain resource not occupied in the first uplink transmission, and no sending or receiving action is performed on the second time domain resource.

In this embodiment, the first uplink transmission may include one or more physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) transmission, and may also include one or more physical uplink control channel (Physical Uplink Control Channel, PUCCH) transmission, etc. , the uplink transmission in subsequent embodiments mostly uses PUXCH as an example to represent the above one or more physical uplink transmission channels. In one example, the first uplink transmission is non-back-to-back transmission.

The first uplink transmission includes unoccupied time-domain resources, that is, second time-domain resources. The second time-domain resources may be referred to as gaps. The second time-domain resources may include one or more symbols. Generally, There are no more than 13 symbols, and no sending or receiving behavior is performed on the second time domain resource.

In the case that the first indication information is not received, the terminal can maintain consistent power and phase to continuously send the first uplink transmission, so that the network side device can perform joint channel estimation (Joint channel estimation) on the first uplink transmission to improve receiving performance . Among them, joint channel estimation refers to a method in which multiple consecutive time slots (slots) in the PUXCH that can maintain consistent power (or called power consistency) and continuous phase jointly perform channel estimation. From the perspective of network-side equipment, it is a network-side The device performs joint channel estimation. On the terminal side, multiple consecutive time slots of PUXCH are transmitted within a predefined or preconfigured time domain window to maintain consistent power and continuous phase. The terminal and the network side device use the same The enabling signaling enables or disables the configuration time domain window, for example, the enabling signaling is designed as PUCCH-TimeDomainWindow-r17, PUSCH-TimeDomainWindow-r17 and so on.

The above-mentioned configured time domain windows can configure one or more through radio resource control (Radio Resource Control, RRC), and a configured time domain window can include multiple consecutive physical slots (slots) or physical symbols (symbols). The length of the configured time-domain window can be configured as a specific value L, which cannot exceed a threshold and cannot exceed the maximum capability of the terminal that may maintain phase consistency (such as maximum duration). L can be configured for each terminal part of the bandwidth (BandWidth Part, BWP), for example, configured in PUSCH-config or PUCCH-config, but it does not exclude configuration in other ways, for example, in the form of per-resource configuration information, configured in PUCCH -config in PUCCH-resource in config, or configure in PUCCH-format0, PUCCH-format1, PUCCH-format2, PUCCH-format3, PUCCH-format4 in PUCCH-config in the form of per-format configuration information.

It should be noted that the time domain windows introduced in subsequent embodiments of the present application, such as actual time domain windows, etc., may be part of the configured time domain windows described above, and the terminal may maintain the first uplink transmission within the time domain window. Consistent power and/or continuous phase; the network side device may perform joint channel estimation for the first uplink transmission within 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, and the first indication information is used to indicate the first The sending or receiving behavior of time domain resources.

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 may be a symbol. In this embodiment, the size of the first time domain resource and the second time domain resource is not limited, as long as there is an intersection between the two resources, the intersection is at least one time domain unit mentioned above. For example, in the case where the second time domain resource is the 9th to 14th symbols of time slot 1, the first time domain resource may be the 9th to 14th symbols of time slot 1, that is, the first time domain resource and The second time domain resource is the same; or, the first time domain resource may be the 10th to 13th symbols of time 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 Including the 9th to 14th symbols of time slot 1, and also including the 9th to 14th symbols of time slot 2, 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 the 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 second time domain resource needs to keep No sending or receiving action is performed, that is, the transmission properties of 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 1. Time domain resources are unavailable. In these situations, the terminal cannot maintain power consistency and phase continuous transmission.

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

In this embodiment, the terminal may use the first processing method to send the first uplink transmission, and the first processing method may be implemented in various ways, for example, performing transmission without maintaining phase continuity, that is, the terminal no longer maintains In the original power consistent and phase continuous transmission, another example is that the terminal and the network side device perform the first uplink transmission according to a default rule.

In the transmission method provided by the embodiment of the present application, the terminal receives the first indication information, the first indication information is used to indicate the sending or receiving behavior of the first time domain resource, and the first time domain resource includes at least one time domain resource in the second time domain resource. In the domain unit, the second time domain resource is a time domain resource not occupied in the first uplink transmission, and no sending or receiving behavior is performed on the second time domain resource, so that the terminal can send the first uplink transmission or stop the first uplink transmission , the embodiment of the present application provides a solution for how the terminal transmits, which helps to improve communication effectiveness.

2) Adjust transmission according to the content indicated by the first indication information. The first uplink transmission may be located within 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 within the actual time domain window. The actual time domain window may be part of the configured time domain window. Whether the actual time domain window can be formed after the first time domain resource or the second time domain resource depends on the specific window information indicated by the first indication information. The capability of the terminal, that is, whether the terminal can maintain power consistency and phase continuity after the first time domain resource or the second time domain resource.

3) performing transmission according to a default rule, where the default rule is used to determine a time domain window, and the time domain window is used to send the first uplink transmission. The first uplink transmission may be located within a configured time domain window. The default rules include, for example: dividing the configured time domain window into multiple actual time domain windows, so that the terminal can maintain consistent power and phase continuous transmission within the actual time domain window. . Whether the actual time domain window can be formed after the first time domain resource or the second time domain resource, in addition to the default transmission rules, also depends on the capability of the terminal, that is, whether the terminal can be in the first time domain resource or the second time domain resource Afterwards, power consistency and phase continuity can still be maintained.

4) Transmission is performed within the range of the first index. For example, the first indicator includes a phase continuity tolerance, and the phase continuity tolerance indicates a maximum phase discontinuity degree that can be tolerated when joint channel estimation is performed.

The first uplink transmission In an example, the first processing method is to adjust the transmission according to the content indicated by the first indication information in 2), and the first indication information also includes at least one of the following:

a) Position information of the time domain window, where the position information of the time domain window is used by the terminal or network side equipment to determine the position of the time domain window.

In an example, the first time domain resource or the second time domain resource may have the same power in the two time domain windows before and after the second time domain resource, and may be able to have continuous phases, or maintain the same power in the two time domain windows. and phase continuity properties. Let the time-domain window length be L, and the position information of the time-domain window indicated by it may be from the nth physical time slot/OFDM symbol to the n+L-1th physical time slot/OFDM symbol, or the From n available time slots/OFDM symbols to n+L-1th available time slots/OFDM symbols, the position information of this group of time slots/symbols. Optionally, the first feature includes: consistent power and/or continuous phase.

b) size (or length) information of the time domain window, where the size information of the time domain window is used by the terminal or network side equipment to determine the size and position of the time domain window. In this example, the terminal keeps the first feature transmission within the determined time domain window (that is, the actual time domain window), and the time domain window does not include the second time domain resource or does not include the first time domain resource . In an example, the first time domain resource or the second time domain resource may have the same power in the two time domain windows before and after the second time domain resource, and may be able to have continuous phases, or maintain the same power in the two time domain windows. and phase continuity characteristics, the length of the time domain window does not exceed the maximum configurable length of the time domain window, and does not exceed the maximum sustainable time for the terminal to maintain phase continuity. Let the time-domain window length be L, the process of determining the time-domain window by the combination of the indicated window size and position information may be the first PUXCH starting with or the first physical time slot/OFDM of the first PUXCH Symbol as a reference, or the first physical slot/OFDM symbol available for the first PUXCH as a reference, calculate the next physical slot/symbol length L, or calculate the next available slot/symbol length L, as the time The position information of the domain window may also refer to the first physical time slot/symbol or the first available time slot/symbol after the first time domain resource or the second time domain resource to calculate the next physical time slot/symbol The symbol length L, or calculate the next available time slot/symbol length L, as the position information of the time domain window, can also use the reference position time slot or reference position symbol that may be included in the first indication information as a reference to calculate the next The physical slot/symbol length L, or the calculated next available slot/symbol length L, is used as the position information of the time domain window. Optionally, the first feature includes: consistent power and/or continuous phase.

c) start information of the time domain window, where the start information of the time domain window is used by the terminal or the network side device to determine the start position of the time domain window. In this example, the terminal keeps the first feature transmission within the determined time domain window (that is, the actual time domain window), and the time domain window does not include the second time domain resource or does not include the first time domain resource . In an example, the first time domain resource or the second time domain resource may have the same power in the two time domain windows before and after the second time domain resource, and may be able to have continuous phases, or maintain the same power in the two time domain windows. and phase continuity properties. For the first time domain window in the first uplink transmission, the start information is the first starting PUXCH, which may be the first physical time slot or physical OFDM symbol of the PUXCH, or the first available slots or OFDM symbols. For the start information of other locations, it is the start information indicated by the first indication information. Optionally, the first feature includes: consistent power and/or continuous phase.

In an example, the first time domain resource or the second time domain resource may have the same power in the two time domain windows before and after the second time domain resource, and may be able to have continuous phases, or maintain the same power in the two time domain windows. and phase continuity properties. The termination information for the last PUXCH transmission is the last physical time slot or physical OFDM symbol, or the last available time slot or available OFDM symbol.

It should be noted that when the PUXCH transmission reaches the terminal's maximum ability to maintain power consistency and phase continuity, the time domain window is automatically terminated. Optionally, the first feature includes: consistent power and/or continuous phase.

The above c) and d) can be used in combination. For example, for a configured time domain window, the terminal determines the first actual time domain window based on the termination information of the time domain window, the start time and configuration of the first actual time domain window The time domain windows are the same; the terminal determines the second actual time domain window based on the termination information of the time domain window, and the termination time of the second actual time domain window is the same as that of the configured time domain window. It is divided into two actual time domain windows. The terminal can maintain the same power and phase continuous transmission in the two actual time domain windows, or have the same power in the two time domain windows and can have continuous phase.

In this example, the terminal keeps the first feature transmission within the determined time domain window (that is, the actual time domain window), and the time domain window does not include the second time domain resource or does not include the first time domain resource . Assuming that the time-domain window length is L, the predefined or pre-configured window length may be one or multiple unequal lengths. The configured time domain window length cannot exceed a maximum length Lmax. For one or more of the configured time-domain window lengths, if the time-domain window length is greater than the maximum capability of the terminal to maintain phase-continuous transmission, the actual time-domain window length is subject to the maximum capability of the terminal to maintain phase-continuous transmission.

The division rule information of the time domain window is used by the terminal or the network side device to divide the configured time domain window to obtain the actual time domain window. In this example, the terminal may also keep the first feature transmission in the actual time domain window, and the actual time domain window does not include the second time domain resource or does not include the first time domain resource. The starting information of the split information is the first starting PUXCH for the first time domain window in the first uplink transmission, which may be the first physical time slot or physical orthogonal frequency division of the PUXCH Multiplexing (Orthogonal frequency division multiplex, OFDM) symbols, or the first available time slot or available OFDM symbols; for the start information of other positions, the information configured by RRC or the predefined rules will be used for implicit Sure. For example, the first indication information is predefined as an event, which is an implicit indication, and the starting position of other time domain windows will be after the first resource indicated by the first indication information or the second resource containing the first resource Then the closest physical slot/symbol or the first available slot/symbol starts. The termination information of the split information, for the last PUXCH transmission, is the last physical time slot or physical OFDM symbol, or the last available time slot or available OFDM symbol. For the termination information at other locations, it will be determined implicitly by using the information configured by the RRC or by using predefined rules. For example, the first indication information is predefined as an event, which is an implicit indication, and the termination position of other time domain windows will be before the first resource indicated by the first indication information or before the second resource including the first resource The nearest last physical slot/symbol or the last available slot/symbol is terminated. In addition, if the window length reaches the maximum capability of the terminal to maintain phase continuity transmission, it will be automatically terminated. Optionally, the first feature includes: consistent power and/or continuous phase.

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 device to perform frequency hopping transmission, after frequency hopping, an actual time domain window can be formed, and the terminal can also maintain the first characteristic transmission in the actual time domain window, so The actual time domain window does not include the second time domain resource or does not include the first time domain resource. For the first time domain window in the first uplink transmission, the frequency hopping start information is the first starting PUXCH, which may be the first physical time slot or physical OFDM symbol of the PUXCH, or The first available time slot or available OFDM symbol; for the frequency hopping start information of other positions, it will be determined implicitly by using the information configured by RRC or by using a predefined rule. For example, RRC pre-configures the position information of frequency hopping, or pre-defines the first indication information as an event, which is an implicit indication, and the starting position of frequency hopping will be after or including the first resource indicated by the first indication information. The first physical time slot/symbol or the first available time slot/symbol closest to the second resource following the first resource starts. The frequency hopping termination information, for the last PUXCH transmission, is the last physical time slot or physical OFDM symbol, or the last available time slot or available OFDM symbol. As for the termination information of frequency hopping at other locations, it will be determined implicitly by using information configured by RRC or by using predefined rules. For example, RRC pre-configures the position information of frequency hopping, or pre-defines the first indication information as an event, which is an implicit indication. The termination position of frequency hopping will be before or including the first resource indicated by the first indication information. The last physical time slot/symbol or the last available time slot/symbol closest to the second resource of a resource is terminated. In addition, if the window length reaches the maximum capability of the terminal to maintain phase continuity transmission, the frequency hopping is automatically terminated. Optionally, the first feature includes: consistent power and/or continuous phase.

6) Pre-defined or pre-configured power-off requirement information. Optionally, the power-off requirement information instructs the terminal to perform an operation of first power-off and then power-on in the second time domain resource, so that the terminal maintains the same power before power-off and after power-on and/or or phase continuous. Alternatively, the power-off request information instructs the terminal to turn off some devices, so that the power change of the terminal is within the range of the power change tolerance, so that the first uplink transmission can maintain phase continuity as much as possible, so that the network side device still Joint channel estimation may be performed on the first uplink transmission.

In each of the above-mentioned embodiments, because a certain event (such as an event that triggers the network side device to send the first indication information) breaks the originally configured configured time domain window, the newly generated time domain window may be called an actual time domain window (actual TDM). ), there may be one or more actual time domain windows. For example, in the subsequent embodiments, the configuration time domain window is the configuration time domain window, and the actual time domain window is considered as the actual time domain window. These actual time domain windows can be indicated in an implicit manner (such as the default rule introduced above), and can also be indicated through the first indication information. The first actual time domain window is considered to be the initially configured time division multiplexing (Time division multiplexing, TDM) in the first PUXCH, which may be the first available or physical slot of PUXCH, or the first available or physical symbol.

Once an actual time domain window starts, its termination depends on the following possibilities: a) This actual time domain window reaches the last PUXCH transmission of the initially configured configuration time domain window, and is automatically terminated. The last PUXCH transmission may be another The last available or physical time slot, or the last available or physical symbol; b) This actual time domain window reaches the maximum duration (maximum duration), that is, the terminal can maintain the maximum capability of phase continuous transmission, and it is automatically terminated; c) Some events have occurred, such as high-priority transmissions conflicting with the current one, precoder cycling is required, etc.

The termination 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. Whether a new actual time domain window can be formed after an event depends on the capability of the terminal. If there is no corresponding capability so that the terminal can still maintain phase-coherent transmission after receiving an event, the phase-coherent transmission will be terminated, that is, there will be no corresponding The actual time-domain window of is generated.

In a case where the first indication information indicates a downlink symbol, there may be no actual downlink transmission on the downlink symbol.

2) Cancellation indication (Cancellation Indication, CI) information, the CI information is used to instruct the terminal to cancel the transmission on the first time domain resource, for example, the CI information indicates the second time domain resource (gap) Canceling the transmission on at least one symbol indicates that the terminal needs to turn off the PA, and the terminal can no longer maintain consistent power, so the phase continuity of the first uplink transmission cannot be guaranteed.

3) Dynamic signaling, where the dynamic signaling is used to indicate that the first time domain resource is unavailable.

In an example, multiple PUSCHs included in the configured time domain window may come from the same TB, which is a form of repetition. For example, this embodiment can be applied in the same TB application scenario where PUSCH type A (type A) and type B (type B) are repeated. In an example, multiple PUSCHs included in the configured time domain window may come from different TBs, which is a form of common transmission. For example, this embodiment can be applied in application scenarios of different TBs.
