Detailed ways

In order to make the technical problems, technical solutions and advantages to be solved by the present disclosure clearer, the following will describe in detail with reference to the drawings and specific embodiments.

It should be understood that reference throughout the specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic related to the embodiment is included in at least one embodiment of the present disclosure. Thus, appearances of "in one embodiment" or "in an embodiment" in various places throughout the specification are not necessarily referring to the same embodiment. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner in one or more embodiments.

In various embodiments of the present disclosure, it should be understood that the sequence numbers of the following processes do not mean Regarding the sequence of execution, the execution sequence of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present disclosure.

Additionally, the terms "system" and "network" are often used interchangeably herein.

In the embodiments provided in the present application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined according to A. However, it should also be understood that determining B according to A does not mean determining B only according to A, and B may also be determined according to A and/or other information.

It should be known that when the terminal supports the transmission of SRS at any position in the time slot, there is: as shown in Figure 1, the symbol of the SRS in the first slot is adjacent to the symbol of the SRS in the second slot ; As shown in Figure 2, the symbol of the last SRS in the first slot is related to the uplink channel in the second slot (such as the physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) or the physical uplink control channel (Physical Uplink Control Channel, The symbols of the PUCCH) are adjacent; as shown in FIG. 3 , the symbols of the last SRS in the second slot are adjacent to the symbols of the first uplink channel (such as PUSCH or PUCCH). In this way, antenna switching may result in the loss of some signal transmissions. For example, in the second slot shown in Figure 3, the last SRS symbol uses a non-primary transmitting antenna, and antenna switching is required to continue the transmission of the uplink channel. During the time of antenna switching, the transmission of PUSCH, PUCCH or other channels cannot be performed.

It should be noted that, in the embodiments provided in this application, the SRS symbol (SRS symbol) is a symbol used for SRS transmission, and the SRS symbol is also called the symbol corresponding to the SRS resource, the symbol of the SRS resource; the symbol of the uplink channel A symbol (uplink channel symbol) is a symbol used for uplink channel transmission, and a symbol of an uplink channel may also be called a symbol corresponding to an uplink channel resource, or a symbol of an uplink channel resource.

As shown in FIG. 4, a sounding reference signal transmission method according to an embodiment of the present disclosure is executed by a terminal, including:

Step 401, determine the guard interval for transmitting the Sounding Reference Signal SRS, the guard interval includes at least one of the following items: the first guard interval between the first SRS resource set and the second SRS resource set, the SRS resource and the uplink channel resource The second guard interval of ;

Step 402, transmit the SRS according to the guard interval.

According to steps 401-402, the terminal can determine the guard period (Guard Period, GP) of SRS transmission, that is, the first guard period between the first SRS resource set and the second SRS resource set, and/or, the SRS resource and The second guard interval between uplink channel resources, followed by the first guard interval and/or transmit SRS in the second guard interval, so as to avoid the time spent on antenna switching occupying actual SRS transmission or uplink channel transmission, resulting in incomplete signal transmission or power instability.

In this embodiment, the uplink channel includes at least one of PUSCH, PUCCH and other uplink channels.

Here, the uplink signal includes but not limited to SRS. Uplink channels include but not limited to PUCCH or PUSCH.

Optionally, step 401 includes:

Here, the configuration information is used to configure the GP, that is, the GP that transmits the SRS, and may also be referred to as the GP of the SRS. That is to say, the GP of the SRS is configured by the network side device, and the terminal can obtain the GP of the SRS by receiving the configuration information.

Optionally, the guard interval includes at least one of the following:

the starting position of the guard interval;

The length of the guard interval.

Here, the length of the guard interval may be indicated by the number of symbols in the guard interval.

Optionally, in this embodiment of the present application, for the first guard interval, if the first condition is met, the length of the first guard interval is equal to zero;

Optionally, the first condition includes at least one of the following:

The SRS resource type in the first time slot is aperiodic, the SRS resource type in the second time slot is periodic or semi-persistent, and the last symbol for transmitting SRS on the first time slot is the same as The number of symbols between the first symbols on the second time slot is greater than or equal to the value of N1.

In this embodiment, zero gap (zero gap) or zero symbol guard interval (zero symbol GP) indicates that the UE can be configured to continuously transmit multiple SRS symbols used for antenna switching or does not need to insert a guard interval symbol or the number of guard interval symbols is 0; or, no guard interval symbols are required or the number of guard interval symbols is 0 between the transmission of the SRS and the transmission of other uplink channels or uplink signals. SRS resource types include: periodic, semi-persistent and aperiodic. N1 is the preset number of symbols of the first GP, and N1 is an integer greater than or equal to 1.

In this way, if the terminal supports zero interval or zero symbol guard interval antenna switching, the length of the first GP is zero; if the first time slot (the time slot corresponding to the first SRS resource set) and the second time slot (the second SRS resource set The SRS resource types in the corresponding time slot) are all periodic or semi-persistent, and the number of symbols between the last SRS transmission symbol on the first time slot and the first symbol on the second time slot is greater than or Equal to the value of N1, the length of the first GP is zero; if the SRS resource type in the first time slot is aperiodic, and the SRS resource type in the second time slot is periodic or semi-persistent, the first time slot The number of symbols between the last symbol of SRS transmission and the first symbol on the second time slot is greater than or equal to the value of N1, and the length of the first GP is zero.

Conversely, if the SRS resource types in both the first time slot and the second time slot are periodic or semi-persistent, the difference between the last SRS transmission symbol on the first time slot and the first symbol on the second time slot The number of symbols between is less than the value of N1, and the length of the first GP is equal to N1 symbols; if the terminal does not support zero interval or zero symbol guard interval antenna switching, the SRS resource types in the first slot and the second slot are not Periodic type, the SRS resource type in the second time slot is periodic or semi-persistent, and the number of symbols between the last SRS transmission symbol on the first time slot and the first symbol on the second time slot is less than The value of N1, the length of the first GP is equal to N1 symbols. Optionally, on the one hand, in this embodiment, the starting position of the first guard interval is the first symbol on the second time slot.

That is, regardless of the resource type of the SRS, the N1 consecutive symbols starting from the first symbol on the second time slot are the first guard interval. At this time, if the SRS transmitted on the second slot overlaps with the first GP, the overlapping SRS symbols or other channel symbols (such as PUSCH or PUCCH channel symbols) are not transmitted.

Optionally, on the other hand, in this embodiment, the starting position of the first guard interval is based on The SRS resource types in the first time slot and the second time slot are determined;

The starting position of the first guard interval is:

That is to say, the SRS resource type in the time slot corresponding to the first SRS resource set is aperiodic, and the SRS resource type in the time slot corresponding to the second SRS resource set is periodic or semi-persistent. N1 symbols starting from the next symbol of one SRS transmission symbol are the first guard interval. Wherein, no SRS, PUSCH, and PUCCH are transmitted on symbols overlapping the second time slot and the N1 symbols. Of course, if there are X symbols between the last symbol for SRS transmission on the first time slot and the first symbol of the second time slot, and X is greater than or equal to N1, then the length of the first guard interval is 0.

Similarly, the SRS resource type in the time slot corresponding to the first SRS resource set and the SRS resource type in the time slot corresponding to the second SRS resource set are both periodic or semi-persistent. The N1 symbols starting from the next symbol of are the first guard interval. Wherein, no SRS, PUSCH, and PUCCH are transmitted on symbols overlapping the second time slot and the N1 symbols. Of course, if there are X symbols between the last symbol for SRS transmission on the first time slot and the first symbol of the second time slot, and X is greater than or equal to N1, then the length of the first guard interval is 0.

That is, for the case where the SRS resource types in both the first time slot and the second time slot are aperiodic, one way is to set N1 N symbols are used as the first guard interval, wherein no SRS, PUSCH, and PUCCH are transmitted on symbols that overlap the second time slot and the N1 symbols. Another way is to use the N1 symbols before the first SRS transmission symbol on the second time slot as the first guard interval, wherein the first time slot and the symbols overlapping the N1 symbols do not transmit SRS, PUSCH, PUCCH.

Optionally, in the case that the SRS resource types in the first time slot and the second time slot are both aperiodic, the starting position of the first guard interval is based on the first SRS resource set and the usage (usage) of the second SRS resource set is determined.

Here, the usage of the SRS resource set may be antenna switching, beam management (beam management) uplink transmission (such as PUSCH based on codebook (codebook) or PUSCH based on non-codebook (non codebook)). For the case that the SRS resource types in the first time slot and the second time slot are both aperiodic, the starting position of the first guard interval is determined based on the usage of the first SRS resource set and the second SRS resource set.

In this embodiment, on the one hand, beam management is used as the lowest priority to determine the starting position of the first guard interval. Optionally, if the first SRS resource set is used for antenna switching, the second SRS resource set is not used for antenna switching, the starting position of the first guard interval is the first position; or

Wherein, not being used for antenna switching may be indicated as being used for beam management or uplink transmission.

That is to say, for the situation that the SRS resource types in the first time slot and the second time slot are both aperiodic, considering that antenna switching is used for downlink MIMO transmission, the downlink is more sensitive to channel state information than the uplink. Sensitive, if the first SRS resource set is used for antenna switching and the second SRS resource set is not used for antenna switching, the starting position of the first guard interval is the first position, That is, the N1 symbols starting from the next symbol of the last SRS transmission symbol on the first time slot are used as the first guard interval; if the first SRS resource set is not used for antenna switching, and the second SRS resource set is used for antenna switching, then The starting position of the first guard interval is the second position, that is, N1 symbols before the first symbol for transmitting the SRS on the second time slot are used as the first guard interval. If the first SRS resource set is used for uplink transmission and the second SRS resource set is used for beam management, the starting position of the first guard interval is the first position, that is, the last transmission on the first time slot The N1 symbols starting from the next symbol of the SRS symbol are used as the first guard interval; if the first SRS resource set is used for beam management and the second SRS resource set is used for uplink transmission, the first guard interval The starting position of is the second position, that is, the N1 symbols before the first SRS transmission symbol on the second time slot are used as the first guard interval. Of course, if the first SRS resource set and the second SRS resource set have the same purpose, the starting position of the first guard interval is the first position or the second position.

In this embodiment, on the other hand, beam management is used as the highest priority to determine the starting position of the first guard interval.
