Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a protection interval determination method, device, terminal and storage medium. Background Art

[0002] The base station obtains downlink channel information for the physical downlink shared channel (PDSCH) by measuring the uplink sounding reference signal (SRS) sent by the terminal. When determining the SRS resource, the terminal will determine the protection interval between two SRS resources. The protection interval needs to be greater than the minimum protection interval requirement, and when the antenna switching SRS conflicts with other signals, the protection interval between SRS resources needs to be considered in the priority determination of the conflict.

[0003] When resources in the existing sounding reference signal resource set SRS resource set are transmitted in different time slots, since SRS can only be configured on the last 6 symbols, the minimum interval requirement must be met between two SRS resources. If they are transmitted in the same time slot, when supporting more symbol resource configurations, the larger interval between SRS resources will cause the corresponding protection interval to be larger, wasting resources. In addition, the current network limits the periodic and semi-continuous antenna switching resource sets to only one, and the non-periodic resource set can support multiple, but they need to be in adjacent time slots. As more antenna switching configurations and more symbol resource configurations are supported, two SRS resource sets may appear in the same time slot, and the resources between the two SRS resource sets may not meet the minimum protection interval requirement. Summary of the invention

[0004] The embodiments of the present application provide a method, device, terminal and storage medium for determining a guard interval, which can solve the problem that the guard interval between SRS resources is too large or the resources between two SRS resource sets may not meet the minimum guard interval requirement.

[0034] The following describes in detail the method and device for determining the protection interval provided by the embodiments of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0035] First, the following contents are explained:

[0036] (1) Antenna switching (used for downlink channel acquisition):

[0037] The base station obtains downlink channel information by measuring the uplink SRS for downlink PDSCH precodering transmission;

[0038] The number of ports in the SRS resource is consistent with the number of terminal antenna ports (tx);

[0039] When used for antenna switching:

[0040] (a)1T2R:

[0041] Configure up to 2 SRS resource sets;

[0042] Each set has different resourceType, that is, different periodic attributes, periodic / semi-continuous / non-periodic. Each set is configured with 2 SRS resources;

[0043] In a set, each SRS resource contains 1 port;

[0044] In a set, each SRS resource needs to be transmitted on a different symbol;

[0045] Within a set, the UE uses different UE antenna ports to send different SRS resources;

[0046] (b)2T4R:

[0047] Configure up to 2 SRS resource sets;

[0048] Each set has a different resourceType, that is, different periodic attributes, periodic / semi-continuous / non-periodic;

[0049] Each set is configured with 2 SRS resources;

[0050] In a set, each SRS resource contains 2 ports;

[0051] In a set, each SRS resource needs to be transmitted on a different symbol;

[0052] In a set, one resource is sent by two UE antenna ports, and another resource is sent by another two UE antenna ports.

[0053] (c)1T4R:

[0054] Configure 0 or 1 SRS resource set;

[0055] resourceType only supports periodic or semi-persistent;

[0056] Configure 4 SRS resources;

[0057] Each SRS resource needs to be transmitted on a different symbol;

[0058] The UE uses different UE antenna ports to send different SRS resources;

[0059] (d)1T4R:

[0060] Configure 0 or 2 SRS resource sets;

[0061] resourceType only supports non-periodic;

[0062] Two sets are configured with a total of 4 SRS resources;

[0063] Each SRS resource contains 1 port;

[0064] The SRS resources configured in the two sets are 2+2, 1+3, or 3+1;

[0065] The values ​​of alpha, p0, pathlossReferenceRS, and srs-PowerControlAdjustmentStates of the two sets are consistent;

[0066] The values ​​of aperiodicSRS-ResourceTrigger or the value of an entry inAperiodicSRS-ResourceTriggerList in two sets are consistent;

[0067] In addition, for aperiodic SRS resource sets, each set needs to be transmitted on two different slots;

[0068] Currently, SRS is supported to be transmitted on the last 6 symbols. The slot offset of all resources in the non-periodic SRS resource set is configured at the set level, that is, the resources in the set are all in the same slot.

[0069] Therefore, the guard period (GP) of antenna switching needs to be guaranteed. Six symbols cannot fit into four resources at once, so two sets need to be forced, and the two sets must be in different slots.

[0070] In addition, for periodic and semi-continuous SRS resource sets, each set does not need to be transmitted on two different slots; because the offset of the resources in the SRS set is configured at the resource level, that is, each resource in the set is different. Even if a set contains 4 resources, the slot offset at the resource level can meet the GP requirement.

[0071] The resources in a set need to be transmitted on two different symbols;

[0072] Each SRS resource in the two sets is associated with an antenna port of a different UE.

[0073] (d)1T1R / 2T2R / 4T4R;

[0074] Configure up to 2 SRS resource sets;

[0075] Each set is configured with one SRS resource;

[0076] The number of SRS ports in each resource is 1 / 2 / 4, which is equal to the number of transmit antennas.

[0077] As shown in Table 1, Table 1 is a table of minimum protection periods between two SRS resources in an SRS resource set for antenna switching.

[0080] Figure 2 is a flowchart of a method for determining a protection interval provided in an embodiment of the present application, such as Figure 2 As shown, the method comprises the following steps:

[0081] Step 200, the terminal determines a target guard interval of two target sounding reference signal resources;

[0082] Step 210: The terminal transmits two target sounding reference signals based on the sounding reference signal resource and the target guard interval;

[0083] The two target detection reference signal resources are any two detection reference signal resources adjacent in the time domain within an antenna switching group;

[0084] Wherein, one antenna switching group includes all the sounding reference signal resources used for detecting a complete channel state information, and the resource type of all the sounding reference signal resources in the one antenna switching group is the same.

[0085] Optionally, when the communication system supports more antenna switching configurations, the number of antenna switching sets is large, the number of resources in a set is also large, and for example, based on UE capabilities, SRS can be configured on 14 symbols, and the symbol position of SRS can occupy any one of the 14 symbols. For example, antenna switching can be increased from a maximum of 4R to 8R, and 2T can also be increased to 4T, that is, at least one of the following configurations can be supported: 1T6R, 1T8R, 2T6R, 2T8R, 4T6R, 4T8R.

[0086] Optionally, the target protection interval corresponding to any two adjacent detection reference signal resources in the time domain within an antenna switching group can be determined to avoid the protection interval being too large. At the same time, since the confirmed target protection interval corresponds to any two adjacent detection reference signal resources in the time domain within an antenna switching group, including SRS resources in different SRS resource sets but adjacent in the time domain, it can effectively avoid the last SRS resource in the previous SRS resource set and the first SRS resource in the next SRS resource set of the two SRS resource sets being connected end to end.

[0087] Optionally, the terminal may determine a target guard interval of any two sounding reference signal resources adjacent in the time domain within an antenna switching group, and then the terminal may transmit two target sounding reference signals based on the sounding reference signal resources and the target guard interval.

[0089] Optionally, the symbol distance or the time slot distance may not include at least one of a downlink time slot and a special time slot, and the downlink time slot may include a time slot in a special time slot containing at least one downlink symbol or a time slot in a special time slot containing all downlink symbols.

[0090] Optionally, an antenna switching group includes all the detection reference signal resources used to detect a complete channel state information, and may include activated or inactivated resources. For example, an initial antenna switching group includes 4 resources, and only 2 resources are activated through the medium access control layer control information (medium access control Control Element, MACCE) of the MAC layer. In this case, the 2 activated resources are the antenna switching group, or even if only 2 resources are activated, the initial antenna switching group is the antenna switching group, which can be used for periodic, semi-continuous, and non-periodic purposes.

[0091] In an embodiment of the present application, the terminal determines the target protection interval of any two adjacent sounding reference signal resources in the time domain within an antenna switching group; and transmits two target sounding reference signals based on the target protection interval, thereby avoiding the defect of a large protection interval when multiple SRS resources are on one SRS resource set when performing some antenna switching configurations. At the same time, the protection interval between SRS resource sets can be determined, thereby avoiding the defect that the resource between two adjacent SRS resource sets does not meet the minimum protection interval requirement, thereby increasing the flexibility of network configuration and improving the performance of antenna switching.

[0108] Optionally, the terminal does not expect that the symbol or time slot distance between multiple SRS resources for antenna switching within an SRS resource set is less than the maximum guard interval;

[0109] Optionally, when the terminal determines the target protection interval of two target sounding reference signal resources, the sounding reference signal resource set where the two target sounding reference signal resources are located satisfies: a protection interval between multiple sounding reference signal resources for antenna switching within the sounding reference signal resource set is less than a maximum protection interval.

[0110] Optionally, the terminal does not expect that a symbol distance or a time slot distance between SRS resources for antenna switching between multiple SRS resource sets is less than a maximum guard interval;

[0111] Optionally, when the terminal determines the target protection interval of two target sounding reference signal resources, the sounding reference signal resource set where the two target sounding reference signal resources are located satisfies: the protection interval between the sounding reference signal resources used for antenna switching in the multiple sounding reference signal resource sets is less than the maximum protection interval.

[0112] Optionally, the maximum protection interval includes a maximum time slot interval or a maximum symbol interval.

[0118] Optionally, the determining a target guard interval of two target sounding reference signal resources includes:

[0119] Based on the time domain positions of the two target sounding reference signal resources, target guard intervals of the two target sounding reference signal resources are determined.

[0120] Optionally, the target protection interval may not necessarily be between the two target detection reference signal resources, but may be adjacent to the two target detection reference signal resources; therefore, the target protection interval of the two target detection reference signal resources may be determined based on the time domain positions of the two target detection reference signal resources.

[0121] Optionally, in the embodiment of the present application, since not all symbols between two target detection reference signal resources are used as target protection intervals, the defect of too large protection intervals can be effectively solved, and setting a protection interval between any two target protection intervals can effectively solve the defect that the protection interval between adjacent detection reference signal resource sets does not meet the requirements.

[0122] Optionally, the determining a target guard interval of the two target sounding reference signal resources based on the time domain positions of the two target sounding reference signal resources includes:

[0127] Optionally, the size of the existing minimum protection interval can be determined as the target protection interval, and the target protection interval and the two target detection reference signal resources are located in adjacent symbols. Then, the specific time domain position of the target protection interval can be determined based on the positions of the two target detection reference signal resources and the size of the target protection interval.
