[0026] Figure 1A block diagram of a wireless communication system applicable to an embodiment of the present application is shown. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 can also be referred to as a terminal device or a user terminal (UE).

[0027] In an embodiment of the present application, a terminal receives first time slot offset information, the first time slot offset information being used to indicate a first time slot offset of a target aperiodic RS resource; and transmits or receives the target aperiodic RS resource at a first time slot position, the first time slot position being obtained by any one of the following: a first time slot offset, a first time slot offset, and a second time slot offset; the second time slot offset being a time slot offset configured for the target aperiodic RS resource. In this solution, determining the first time domain position by the first time slot offset, or determining the first time domain position by the first time slot offset and the second time slot offset, increases the selectivity and flexibility of determining the time domain position at which the terminal transmits or receives the aperiodic RS resource, thereby resolving the problem of insufficient flexibility in determining the time slot position of the terminal transmitting or receiving the aperiodic RS resource in the related art. Furthermore, the selectivity and flexibility of the time domain position for transmitting the DCI for activating the aperiodic RS resource are increased, i.e., the selectivity and flexibility of the time domain position for transmitting the PDCCH are increased, thereby resolving, to a certain extent, the problem of PDCCH resource congestion caused by transmitting multiple DCIs in the same time slot in the related art.

[0028] The following, in combination with the accompanying drawings, describes in detail the non-periodic RS transmission method, terminal and network-side equipment provided in the embodiments of the present application through some embodiments and their application scenarios.

[0029] Based on Figure 1 In the communication system shown, an embodiment of the present application provides a non-periodic RS transmission method, as shown in Figure 2(a). The non-periodic RS transmission method may include the following steps 201 to 203.

[0030] Step 201: The terminal receives first time slot offset information.

[0031] The first time slot offset information is used to indicate the first time slot offset of the target non-periodic RS resource.

[0032] Step 202: The terminal sends or receives the target aperiodic RS resource at the first time slot.

[0033] The first time slot position is obtained by any one of the following: a first time slot offset, a first time slot offset and a second time slot offset; the second time slot offset is: a time slot offset configured for a target non-periodic RS resource.

[0034] Optionally, the network side device sends the first time slot offset information accordingly. As shown in FIG2(b), in the embodiment of the present application, before step 201, the aperiodic RS transmission method provided in the embodiment of the present application may further include step 201a, and the above step 201 may be specifically implemented by the following step 201b.

[0035] Step 201a: The network-side device sends first time slot offset information to the terminal.

[0036] Step 201b: The terminal receives first time slot offset information from the network side device.

[0037] Optionally, as shown in FIG2( b ), in an embodiment of the present application, the non-periodic RS transmission method provided in the embodiment of the present application may further include the following step 203 .

[0038] Step 203: The network-side device sends or receives target aperiodic RS resources at the first time slot position.

[0039] Exemplarily, the target aperiodic RS includes an aperiodic uplink RS, such as an SRS. Step 202 is for the terminal to transmit the aperiodic uplink RS at the first time slot. Correspondingly, step 203 is for the network-side device to receive the aperiodic uplink RS at the first time slot. Alternatively, the target aperiodic RS includes an aperiodic downlink RS, such as a CSI-RS or a Positioning Reference Signal (PRS). Step 202 is for the terminal to receive the aperiodic downlink RS at the first time slot. Correspondingly, step 203 is for the network-side device to transmit the aperiodic downlink RS at the first time slot.

[0040] In an embodiment of the present application, when the first time slot position is determined by the first time slot offset, the sending or receiving time slot position of the non-periodic RS resource can be effectively determined, making the method of determining the sending or receiving time slot position of the non-periodic RS resource more flexible.

[0041] In the embodiment of the present application, when the first time slot position is obtained by the first time slot offset and the second time slot offset, compared to the solution in the related art where the first time slot position is determined by the second time slot offset, the method for determining the sending or receiving time slot position of the aperiodic RS resource is more flexible, and the aperiodic RS resource can be better sent or received. In addition, the method for determining the time domain position of sending the DCI for activating the aperiodic RS resource is also more flexible. Even more flexible is the method for determining the time domain position of sending the PDCCH. This can, to a certain extent, solve the problem of PDCCH resource congestion caused by sending multiple DCIs in the same time slot in the related art.

[0042] Optionally, the target aperiodic RS resource includes at least one of the following: a target aperiodic SRS resource and a target aperiodic CSI-RS resource.

[0043] It should be noted that, in the embodiment of the present application, the target non-periodic RS resource may also be other types of non-periodic RS resources, which may be determined based on actual conditions and is not limited in the embodiment of the present application.

[0044] Optionally, when the target aperiodic RS resource includes a target aperiodic SRS resource, the target aperiodic SRS resource is: at least one aperiodic SRS resource in the aperiodic SRS resource set. It is understood that the target aperiodic SRS resource is: one aperiodic SRS resource, two aperiodic SRS resources, multiple aperiodic SRS resources, or all aperiodic SRS resources in the aperiodic SRS resource set, which is not limited in the embodiments of the present application.

[0045] Optionally, when the target aperiodic RS resource includes a target aperiodic SRS resource, the target aperiodic SRS resource is: at least one enabled aperiodic SRS resource (among all aperiodic SRS resources) in the aperiodic SRS resource set.

[0046] Exemplarily, the above steps 202 to 203 may be specifically implemented through the following steps 202a to 203a.

[0047] Step 202a: The terminal sends a target aperiodic SRS resource to the network-side device at the first time slot.

[0048] Step 203a: The network-side device receives a target aperiodic SRS resource from the terminal at the first time slot position.

[0049] Optionally, in an embodiment of the present application, when the target information is RRC signaling, if the network side device configures the first time slot offset information in the non-periodic SRS set, all non-periodic SRS resources in the non-periodic SRS set share one first time slot offset information; if the network side device configures the first time slot offset information in the non-periodic SRS resource, each non-periodic SRS resource in the non-periodic SRS set is separately configured with one first time slot offset information; if the network side device configures multiple first time slot offset information in the non-periodic SRS set, each first time slot offset information corresponds to at least one non-periodic SRS resource, then at least one non-periodic SRS resource in the non-periodic SRS set is configured with one first time slot offset information.

[0050] Optionally, when the target aperiodic RS resource includes a target aperiodic CSI-RS resource, the target aperiodic CSI-RS resource is: at least one aperiodic CSI-RS resource associated with the aperiodic CSI report. It will be understood that the target aperiodic CSI-RS resource is: one aperiodic CSI-RS resource, two aperiodic CSI-RS resources, multiple aperiodic CSI-RS resources, or all aperiodic CSI-RS resources associated with the aperiodic CSI report.

[0051] Optionally, when the target aperiodic RS resource includes a target aperiodic CSI-RS resource, the target aperiodic CSI-RS resource is: at least one enabled aperiodic CSI-RS resource (among all aperiodic CSI-RS resources) associated with the aperiodic CSI report.

[0052] Exemplarily, the above steps 202 to 203 can be specifically implemented through the following steps 202b to 203b.

[0053] Step 202b: The network-side device sends a target aperiodic CSI-RS resource to the terminal at the first time slot position.

[0054] Step 203b: The terminal receives a target aperiodic CSI-RS resource from the network-side device at the first time slot position.

[0055] Optionally, in an embodiment of the present application, when the target information is RRC signaling, if the network side device configures the first time slot offset information in the non-periodic CSI report, all non-periodic CSI-RS resources associated with the non-periodic CSI report share one first time slot offset information; if the network side device configures the first time slot offset information within the non-periodic CSI resource, each CSI-RS resource associated with the non-periodic CSI report is separately configured with one first time slot offset information; if the network side device configures multiple first time slot offset information within the non-periodic CSI resource, each first time slot offset information corresponds to at least one non-periodic SRS resource associated with the non-periodic CSI report, then at least one non-periodic SRS resource associated with the non-periodic CSI report is configured with one first time slot offset information.

[0056] Optionally, the above step 201 can be specifically implemented through the following step 201c.

[0057] Step 201c: The terminal receives target information.

[0058] The target information includes a time slot offset indication field, which carries first time slot offset information; the target information is at least one of the following: RRC signaling, DCI, and first Media Access Control Element (MAC CE) signaling. The target information may also be other signaling, which is not limited in the embodiments of the present application.

[0059] Accordingly, the network side device sends the target information.

[0060] Optionally, the above steps 201a to 201b can be specifically implemented through the following steps 201d to 201e.

[0061] Step 202d: The terminal receives target information from the network side device.

[0062] Step 201e: The network side device sends target information to the terminal.

[0063] Optionally, in an embodiment of the present application, the first time slot offset information may be indicated solely through one signaling, or may be indicated jointly through multiple signalings.

[0064] Exemplarily, when the target information is DCI or the first MAC CE signaling, the first time slot offset information is: a time slot offset information in a time slot offset information set, and the time slot offset information set is configured for the terminal by RRC signaling or the second MAC CE signaling.

[0065] It should be noted that the first MAC CE signaling and the second MAC CE signaling may be the same signaling or different signaling.

[0066] Optionally, in a case where the time slot offset information set is configured for the terminal by the second MAC CE signaling, the network side device may update the time slot offset information set through the MAC CE signaling.

[0067] Optionally, when the time slot offset information set is empty, the time slot offset indication field is: 0 bit.

[0068] Optionally, before the above step 202, the aperiodic RS transmission method provided in the embodiment of the present application may further include the following steps 204 to 205.

[0069] Step 204: The network-side device sends target request information to the terminal.

[0070] Step 205: The terminal receives target request information from the network side device.

[0071] Among them, the target request information includes a target activation indication field, which is used to indicate whether to activate the target non-periodic RS resource; when the target activation indication field does not exist or the target activation indication field indicates not to activate the target non-periodic RS resource, the time slot offset indication field is: 0 bit.

[0072] Optionally, in an embodiment of the present application, the above-mentioned target information and target request information may be the same information signal or different signalings, which is not limited in the embodiment of the present application.

[0073] Exemplarily, when the target information is RRC signaling or MAC CE signaling, the target request information is DCI; when the target information is DCI, the target request information is also DCI. At this time, the target information and the target request information are two pieces of information carried in the same DCI.

[0074] It can be understood that when the target activation indication field does not exist (ie, the target activation indication field is 0 bit) or the target activation indication field indicates that the target aperiodic RS resource is not activated (the value is 0 (ie, '0' or '00')), the time slot offset indication field is: 0 bit.

[0075] Exemplarily, the target activation indication field in the DCI used to indicate whether to activate the aperiodic SRS resource is the SRS request field. When the SRS request field is 0 bit or has a value of 0 (ie, '0' or '00'), the slot offset indication field is 0 bit.

[0076] Exemplarily, the target activation indication field in the DCI used to indicate whether to activate the aperiodic CSI-RS resource is the CSI request field. When the CSI request field is 0 bit or has a value of 0 (ie, '0' or '00'), the slot offset indication field is 0 bit.

[0077] It should be noted that in the embodiment of the present application, the SRS request is 2 bits or 3 bits. When the cell where the terminal is located does not support SUL, the SRS request is 2 bits. When the cell where the terminal is located supports SUL, the SRS request is 3 bits. The size of the CSI request is determined by a higher-layer parameter (reportTriggerSize). The CSI request can be m bits, where m is a natural number, for example, 0, 1, 2, 3, 4, 5, 6, or other values.

[0078] In the embodiment of the present application, the flexibility of setting the time slot offset indication field is increased.

[0079] Optionally, the target non-periodic RS resource is a target non-periodic SRS resource, the target request information is the first request information, the target activation indication field is the first activation indication field, and when the first activation indication field indicates activation of the target non-periodic SRS resource, the first time slot offset information is used to indicate: the first time slot offset of the target non-periodic SRS resource.

[0080] Exemplarily, the above steps 204 to 205 can be specifically implemented through the following steps 204a to 205a.

[0081] Step 204a: The network-side device sends a first request message to the terminal.

[0082] Step 205a: The terminal receives first request information from the network side device.

[0083] Among them, the first request information includes a first activation indication field, which is used to indicate whether to activate the target non-periodic SRS resource; when the first activation indication field indicates to activate the target non-periodic SRS resource, the first time slot offset information is used to indicate: the first time slot offset of the target non-periodic SRS resource; the target non-periodic RS resource is the target non-periodic SRS resource.

[0084] Optionally, the target non-periodic RS resource is a target non-periodic CSI-RS resource, the target request information is the second request information, the target activation indication field is the second activation indication field, and when the second activation indication field indicates activation of the target non-periodic CSI-RS resource, the first time slot offset information is used to indicate: the first time slot offset of the target non-periodic CSI-RS resource.

[0085] Exemplarily, the above steps 204 to 205 can be specifically implemented through the following steps 204b to 205b.

[0086] Step 204b: The network-side device sends a second request message to the terminal.

[0087] Step 205b: The terminal receives second request information from the network side device.

[0088] Among them, the second request information includes a second activation indication field, which is used to indicate whether to activate the target non-periodic CSI-RS resource; when the second activation indication field indicates the activation of the target non-periodic CSI-RS resource, the first time slot offset information is used to indicate: the first time slot offset of the target non-periodic CSI-RS resource; the target non-periodic RS resource is the target non-periodic CSI-RS resource.

[0089] In an embodiment of the present application, by setting that when the SRS request field indicates activation of SRS resources, the first time slot offset information is used to indicate: the first time slot offset of the target non-periodic SRS resource; when the CSI request field indicates activation of CSI-RS resources, the first time slot offset information is used to indicate: the first time slot offset of the target non-periodic CSI-RS resource, which can increase the indication flexibility and diversity of the first time slot offset information.

[0090] Optionally, in an embodiment of the present application, the time slot offset indication field may be one indication field, or two indication fields, or other feasible situations, which are not limited in the embodiment of the present application.

[0091] Exemplarily, the time slot offset indication field includes at least one of the following: a first indication field and a second indication field;

[0092] The first indication field is used to carry first offset information, which is used to indicate the first time slot offset of the non-periodic SRS resource; the second indication field is used to carry second offset information, which is used to indicate the first time slot offset of the non-periodic CSI-RS.

[0093] It should be noted that the description of the above-mentioned first indication field and the second indication field refers to the above-mentioned description of the time slot offset indication, and will not be repeated here; the description of the above-mentioned first offset information and the second offset information refers to the above-mentioned description of the first time slot offset information, and will not be repeated here.

[0094] It can be understood that when the time slot offset indication field is one indication field, there are the following three situations:

[0095] In the first case, the time slot offset indication field is only used for aperiodic SRS resources. In this case, the time slot offset indication field is a first indication field, and the first offset information (i.e., the first time slot offset information) is used to indicate the first time slot offset of the aperiodic SRS resource.

[0096] In the second case, the time slot offset indication field is used only for aperiodic CSI-RS resources. In this case, the time slot offset indication field is the second indication field, and the second offset information (i.e., the first time slot offset information) is used to indicate the first time slot offset of the aperiodic CSI-RS resource.

[0097] In the third case, the time slot offset indication field is used for non-periodic SRS resources and non-periodic CSI-RS resources (non-periodic SRS resources and non-periodic CSI-RS resources share one indication field). In this case, the time slot offset indication field is the first indication field and the second indication field. The first indication field and the second indication field are the same indication field. The first offset information and the second offset information are the same offset information (i.e., the first time slot offset information). Furthermore, the first time slot offset information can be used to indicate the first time slot offset of the non-periodic SRS resources, and can also be used to indicate the first time slot offset of the non-periodic CSI-RS resources.

[0098] It is understandable that the third situation mentioned above may specifically include the following three situations:

[0099] 1. The first time slot offset information indicates both the first time slot offset of the aperiodic SRS resource and the first time slot offset of the aperiodic CSI-RS resource.

[0100] 2. When the SRS request field is not 0 (ie, the SRS request field indicates activation of the aperiodic SRS resource), the first time slot offset information indicates the first time slot offset of the aperiodic SRS resource.

[0101] 3. When the CSI request field is not 0 (ie, the CSI request field indicates activation of aperiodic CSI-RS resources), the first time slot offset information indicates the first time slot offset of the aperiodic CSI-RS.

[0102] It can be understood that when the time slot offset indication field is two indication fields, one is used for non-periodic SRS resources (ie, the first indication field is used for non-periodic SRS resources), and the other is used for non-periodic CSI-RS resources (ie, the first indication field is used for non-periodic CSI-RS resources).

[0103] In the embodiment of the present application, multiple possible forms of the time slot offset indication field are added, which can better solve the problem of PDCCH congestion.

[0104] Optionally, the first time slot offset information includes offsetting N target time slots, where any target time slot is any of the following: an uplink time slot, a downlink time slot, a special time slot, a valid time slot, an enabled time slot, or an arbitrary time slot, and N is a natural number.

[0105] It should be noted that, in the embodiment of the present application, the order of shifting according to the first offset information and shifting according to the second time slot offset is not limited. For example, the communication device (after receiving the DCI for activating the target non-periodic RS resource) can first shift according to the second time slot offset, and then shift according to the first offset information to obtain the first time slot position; or it can first shift according to the first offset information, and then shift according to the second time slot offset to obtain the first time slot position.

[0106] It can be understood that in the embodiment of the present application, shifting by N target time slots means shifting to the Nth target time slot.

[0108] In an embodiment of the present application, when the first time slot position is obtained by the first time slot offset, the first time slot offset information is an offset of N target time slots. Compared with the solution in the related art in which the first time slot position is determined by the second time slot offset, the method for determining the sending or receiving time slot position of the aperiodic RS resource is more flexible, and the aperiodic RS resource can be better sent or received. In addition, the method for determining the time domain position of the DCI for activating the aperiodic RS resource is also more flexible. Even if the method for determining the time domain position of sending the PDCCH is more flexible, this can, to a certain extent, solve the problem of PDCCH resource congestion caused by sending multiple DCIs in the same time slot in the related art.

[0109] Optionally, when the first time slot offset information is not configured, N is a default value. The default value may be any preset value, which may be determined based on actual usage requirements and is not limited in the present embodiment.

[0110] Exemplarily, when the time slot offset indication field associated with the non-periodic SRS or non-periodic CSI-RS is not configured (i.e., the first time slot offset information is not configured), N is 0 or 1, that is, the first time slot offset information is an offset of 0 target time slots or an offset of 1 target time slot, that is, an offset to the 0th target time slot or an offset to the 1st target time slot.

[0111] Exemplarily, when the target information is DCI, if the time slot offset indication field is 1 bit (that is, the value of the time slot offset indication field is '0' or '1'), the first time slot offset information can be an offset to the first target time slot or an offset to the second target time slot, and the first time slot offset information can also be an offset to the 0th target time slot or an offset to the first target time slot.

[0112] Exemplarily, in the case where the target information is DCI, if the time slot offset indication field is 2 bits (that is, the value of the time slot offset indication field is '00' or '01', '10' or '11'), the first time slot offset information can be an offset to the 1st target time slot, or an offset to the 2nd target time slot, or an offset to the 3rd target time slot, or an offset to the 4th target time slot. The first time slot offset information can also be an offset to the 0th target time slot, or an offset to the 1st target time slot, or an offset to the 2nd target time slot, or an offset to the 3rd target time slot.

[0113] Exemplarily, when the target aperiodic RS resource is an aperiodic SRS resource, the target time slot may include an uplink time slot and a special time slot that can be used for uplink transmission. When the target aperiodic RS resource is an aperiodic CSI-RS resource, the target time slot may include a downlink time slot and a special time slot that can be used for downlink transmission.

[0114] In the embodiment of the present application, any time slot refers to any time unit on the time slot resource, and offsetting N arbitrary time slots refers to offsetting N consecutive time slots.

[0115] In the embodiment of the present application, the description of the above-mentioned uplink time slot, downlink time slot, special time slot, valid time slot and enabled time slot can refer to the description in the relevant technology and will not be repeated here.

[0116] Optionally, the valid time slot is a time slot resource that can be used to transmit the target aperiodic RS resource. It can be understood that the valid time slot is a time slot resource that can be used to transmit all symbol resources in the target aperiodic RS resource.

[0117] Exemplarily, when the target aperiodic RS resource is a target aperiodic SRS resource, the valid time slot is a time slot resource that can be used to transmit all symbol resources in the target aperiodic SRS resource, wherein the target aperiodic SRS resource is at least one aperiodic SRS resource in the aperiodic SRS resource set.

[0118] Exemplarily, when the target aperiodic RS resource is a target aperiodic CSI-RS resource, the valid time slot is a time slot resource that can be used to transmit all symbol resources in the target aperiodic CSI-RS resource. The target aperiodic CSI-RS resource is at least one aperiodic CSI-RS resource associated with an aperiodic CSI report.

[0119] Furthermore, the valid time slot is a time slot resource within the valid window that can be used to transmit the target non-periodic RS resource. For the description of the valid window, please refer to the description of the valid window below, which will not be repeated here.

[0121] It can be understood that when the first time slot position satisfies the requirement of being within the valid window, the first time slot position may be any time slot within the valid window, or may be an enabled time slot within the valid window.

[0122] Optionally, the effective window is determined by at least one of the following: network-side device configuration, protocol agreement, and terminal reporting. It is understood that the effective window may be determined by one of the following: network-side device configuration, protocol agreement, and terminal reporting, or by a combination of the following: network-side device configuration, protocol agreement, and terminal reporting. The specific determination may be based on actual usage requirements.

[0123] Optionally, the time slot template of the valid window is determined by at least one of the following: network side device configuration, protocol agreement, and terminal reporting; it can be understood that the time slot template of the valid window is determined by one of the network side device configuration, protocol agreement, and terminal reporting, or the time slot template of the valid window is determined jointly by multiple items of network side device configuration, protocol agreement, and terminal reporting, which can be determined specifically according to actual usage requirements.

[0124] Optionally, the time slot template includes the starting point of the effective window, the window length of the effective window, and the time slot distribution within the effective window. The time slot distribution within the effective window refers to the distribution of uplink time slots, downlink time slots, special time slots, effective time slots, and enabled time slots within the effective window.

[0125] Optionally, the time slot template includes a starting point of the valid window, a window length of the valid window, and a position distribution of enabled time slots within the valid window.

[0126] It can be understood that the valid window can be a continuous time slot window, that is, the enabled time slots in the valid window are continuous; the valid window can also be a discontinuous time slot window, that is, the enabled time slots in the valid window are discontinuous.

[0127] Optionally, when the first time domain position is an enabled time slot within the valid window, the terminal (or network side device) sends or receives the target aperiodic RS resource at the first time slot position. When the first time slot position is a time slot position other than the four enabled time slots, the terminal (or network side device) may not send or receive the target aperiodic RS resource time slot.

[0128] For example, the starting point of the valid window may be determined by a protocol agreement. The length of the valid window may be determined by any of the following: network-side device configuration, protocol agreement, or terminal reporting. The location distribution of enabled time slots within the valid window is configured by the network-side device.

[0129] Optionally, the starting point of the effective window is located at: the second time slot position, or the third time slot position; wherein the third time slot position is: the time slot position obtained by offsetting the second time slot position by the second time slot offset amount. The starting point of the effective window can also be located at other time slot positions, which is not limited in the embodiments of the present application.

[0130] Optionally, the window length of the effective window may be infinite, which is equivalent to having no effective window.

[0131] Exemplarily, the time slot template is 1000100101. The window length of the valid window is 10 slots (time slots), which can be configured by the network or reported by the terminal through an indication method such as a bitmap. The slot indicating the position of 1 represents the position distribution of the enabled time slots within the valid window. When the enabled time slot within the valid window is the target time slot, the first time slot offset information is an offset to the first enabled time slot within the valid window, which means an offset to the time slot position indicated by the first 1. Similarly, the first time slot offset information is an offset to the second enabled time slot within the valid window, which means an offset to the time slot position indicated by the second 1.

[0132] Exemplarily, the time slot template may be determined based on whether the activated target aperiodic RS resource is an uplink resource or a downlink resource. If the activated target aperiodic RS resource is an uplink resource, the time slot template may only include time slot resources that can be used for uplink transmission, and / or, if the activated target aperiodic RS resource includes an uplink resource, the time slot template may only include time slot resources that can be used for downlink transmission.
