Description

Reference signal transmission method and communication device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on August 4, 2023, with application number 2023109804110 and application name “Reference Signal Transmission Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a reference signal transmission method and a communication device. Background Art

[0003] With the further evolution of 5G technology, in order to reduce the cost of terminal devices, the channel bandwidth of terminal devices has been further reduced, especially for terminal devices in IoT scenarios. In many application scenarios, terminal devices have high-precision positioning requirements. Positioning accuracy is usually closely related to the channel bandwidth of the terminal device. The larger the bandwidth, the higher the positioning accuracy. Therefore, if the RF bandwidth of the terminal device is not large enough, the terminal device cannot send the sounding reference signal (SRS) on a larger bandwidth at the same time. In this case, the terminal device sends the SRS by frequency hopping, that is, the terminal device can send the SRS multiple times on different frequency domain resources in a time division multiplexing (TDM) manner (i.e., on different time domain resources). The positioning accuracy is improved by combining the transmission of SRS on multiple different frequency domain resources. In existing protocols, the resources used to carry SRS may collide with other physical channel resources. How to reduce resource collisions in SRS frequency hopping transmission is an urgent problem to be solved.

[0004] Summary of the Invention

[0005] The embodiments of the present application provide a reference signal transmission method and a communication device, wherein SRS transmission is performed in an uplink transmission window, thereby reducing resource collision.

[0006] In a first aspect, an embodiment of the present application provides a reference signal transmission method, the method comprising:

[0007] receiving configuration information, where the configuration information is used to configure a time domain position of an uplink sending window;

[0008] An uplink sending window is determined according to the configuration information, and a sounding reference signal SRS is sent in the uplink sending window.

[0009] Based on the description of the first aspect, the terminal device receives configuration information for determining the time domain position of the uplink sending window, thereby determining the uplink sending window according to the configuration information, and sending SRS in the determined uplink sending window. Since the SRS is sent in a specific uplink sending window, collisions with other physical channel resources can be reduced.

[0010] In an optional implementation manner, the configuration information indicates at least one of the following: the length of the uplink sending window, the starting position of the uplink sending window, and the period of the uplink sending window.

[0011] By implementing this approach, the information of the uplink sending window can be indicated through configuration information, thereby facilitating determination of the time domain position of the uplink sending window.

[0012] In an optional implementation manner, the configuration information is configured for an SRS resource, or the configuration information is configured for an SRS resource set to which the SRS resource belongs;

[0013] The SRS resource is a time-frequency resource used to carry the SRS.

[0014] When implementing this method, the configuration information can be specifically configured for SRS resources, or specifically configured for the SRS resource set to which the SRS resources belong, thereby improving the flexibility of uplink sending window configuration, improving the utilization of the uplink sending window, and thus reducing the impact of the uplink sending window on data transmission.

[0015] In an optional implementation, the configuration information includes the length of the uplink sending window; and the method further includes:

[0016] Receiving downlink control information (DCI) or a media access control element (MAC CE), where the DCI or MAC CE indicates a first offset, where the first offset is a time offset after an end position of a received resource of the DCI or MAC CE;

[0017] Determining a starting position of the uplink sending window according to the first offset and an end position of a receiving resource of the DCI or MAC CE;

[0018] The determining the uplink sending window according to the configuration information includes:

[0019] The uplink sending window is determined according to a starting position of the uplink sending window and a length of the uplink sending window.

[0020] In this implementation, the length of the uplink sending window is configured by configuration information, and the starting position of the uplink sending window is dynamically indicated by the DCI or MAC CE. That is, the uplink sending window is indicated only when needed. This can improve the utilization of the uplink sending window, reduce the impact of the uplink sending window on data transmission, and reduce resource collisions.

[0021] In an optional implementation, the configuration information includes the length of the uplink sending window; and the method further includes:

[0022] Determining a starting position of the uplink sending window according to a time domain starting position of a first SRS resource, where the first SRS resource is an SRS resource with the earliest time domain starting position in at least one SRS resource set triggered by a DCI or a MAC CE;

[0023] The determining the uplink sending window according to the configuration information includes:

[0024] The uplink sending window is determined according to a starting position of the uplink sending window and a length of the uplink sending window.

[0025] In implementing this method, the length of the uplink sending window is configured by the configuration information, and the first SRS resource with the earliest time domain starting position in at least one SRS resource set triggered by DCI or MAC CE is determined, the starting position of the uplink sending window is determined according to the first SRS resource, and then the uplink sending window is determined according to the starting position of the uplink sending window and the length of the uplink sending window configured by the configuration information. When SRS needs to be transmitted, the uplink sending window can be determined by the first SRS resource with the earliest time domain starting position, so that the uplink sending window can encompass the SRS resources as much as possible, improve the utilization rate of the uplink sending window, reduce the impact of the uplink sending window on data transmission, and reduce resource collisions.

[0026] In an optional implementation manner, determining the starting position of the uplink sending window according to the time domain starting position of the first SRS resource includes:

[0027] The starting position of the uplink sending window is determined according to the time domain starting position of the first SRS resource and a second offset, where the second offset is a time offset relative to the time domain starting position of the first SRS resource.

[0028] By implementing this approach, the time domain starting position of the first SRS resource can be shifted forward to a position determined by the second offset as the starting position of the uplink sending window, thereby improving the reliability of SRS transmission.

[0029] In an optional implementation, the configuration information includes a third offset and a fourth offset, the third offset being a time offset before a time domain start position of an SRS resource, and the fourth offset being a time offset after a time domain end position of the SRS resource, where the SRS resource is a time-frequency resource used to carry the SRS;

[0030] The determining the uplink sending window according to the configuration information includes:

[0031] Determining a starting position of the uplink sending window according to the third offset and a time domain starting position of the SRS resource;

[0032] Determining an end position of the uplink sending window according to the fourth offset and the time domain end position of the SRS resource;

[0033] The uplink sending window is determined according to the starting position and the ending position.

[0034] By implementing this method, the third offset forward of the time domain starting position of the SRS resource and the fourth offset backward of the time domain starting position of the SRS resource can be configured through configuration information, so that the uplink sending window suitable for the SRS resource can be determined according to the specific SRS resource, thereby improving the utilization rate of the uplink sending window.

[0035] In an optional implementation, the initial state of the uplink sending window is an activated state;

[0036] The sending a sounding reference signal SRS in the uplink sending window includes:

[0037] The SRS is sent in the uplink sending window that is in the activated state.

[0038] By implementing this approach, SRS is sent in the activated uplink sending window instead of sending SRS in all uplink sending windows, which can improve the utilization of the uplink sending window.

[0039] In an optional embodiment, the method further includes:

[0040] receiving first indication information, where the first indication information is used to instruct deactivation of N consecutive uplink sending windows, where N is an integer greater than or equal to 1;

[0041] Data transmission is performed in the deactivated N consecutive uplink sending windows.

[0042] By implementing this approach, N consecutive uplink sending windows can be deactivated through the first indication information, and data transmission can be performed in the deactivated N consecutive uplink sending windows, thereby reducing the impact on data transmission.

[0043] In an optional implementation, the initial state of the uplink sending window is an inactive state; and the method further includes:

[0044] receiving second indication information, where the second indication information is used to instruct activation of M consecutive uplink sending windows, where M is an integer greater than or equal to 1;

[0045] The sending a sounding reference signal SRS in the uplink sending window includes:

[0046] The SRS is sent in the activated M consecutive uplink sending windows.

[0047] When this method is implemented, the initial state of the uplink sending window is an inactive state. The network can activate M consecutive uplink sending windows through the second indication information, and send SRS in the activated M uplink sending windows. That is, the uplink sending window is activated when SRS needs to be sent, so that SRS is sent in the uplink sending window. This can improve the utilization rate of the uplink sending window and reduce the impact on data transmission, thereby reducing resource collisions.

[0048] In an optional implementation, the value of N or M is preconfigured.

[0049] By implementing this approach, the number of uplink sending windows to be activated or deactivated can be preconfigured, which can reduce signaling overhead.

[0050] In an optional implementation, the value of N is one of a plurality of first candidate values; the first indication information includes first numerical indication information, and the first numerical indication information is used to indicate the value of N;

[0051] The value of M is one of multiple second candidate values; the second indication information includes second numerical indication information, and the second numerical indication information is used to indicate the value of M.

[0052] In this implementation, the value of N may be indicated by the first indication information, and the value of M may be indicated by the second indication information, so that the number of activated or deactivated uplink sending windows can be flexibly determined.

[0053] In an optional implementation, the first indication information or the second indication information is carried in a DCI or a MAC CE.

[0054] By implementing this method, the first indication information or the second indication information is carried in the DCI or MAC CE, thereby avoiding the introduction of new signaling and reducing interactive signaling.

[0055] In an optional implementation manner, the sending a sounding reference signal SRS in the uplink sending window includes:

[0056] In response to the uplink sending window overlapping with the measurement gap, an SRS is sent in the uplink sending window.

[0057] By implementing this approach, when the uplink sending window overlaps with the measurement gap, the SRS is still sent in the uplink sending window, giving priority to ensuring the reliability of SRS transmission.

[0188] The following explains some of the terms involved in the embodiments of the present application to facilitate understanding by those skilled in the art.

[0189] SRS resources and SRS frequency hopping patterns: One SRS resource corresponds to the transmission resources required for an SRS frequency hopping pattern. Figure 1b shows a schematic diagram of an SRS resource. An SRS resource can contain multiple SRS frequency hopping events. The pattern formed by these multiple SRS frequency hopping events is the SRS frequency hopping pattern. An SRS frequency hopping event can be understood as a block of time-frequency resources used for SRS transmission.

[0190] In some implementations, the SRS resource configuration may include time domain parameters of the SRS resource, such as the time domain starting position of the SRS resource, the period, the time interval between two adjacent SRS frequency hops within an SRS resource, the starting symbol of the first SRS frequency hop, the number of symbols occupied by each SRS frequency hop, etc. The period of the SRS resource can be understood as the repetition period of the SRS frequency hopping pattern, as shown in Figure 1b, where T is the period of the SRS resource. The SRS resource configuration may also include frequency domain parameters of the SRS resource, such as the frequency domain starting position of the SRS resource, the frequency domain interval between two adjacent SRS frequency hops within an SRS resource, and the bandwidth of each SRS frequency hop.

[0191] The SRS resources configured by the network may collide with other physical channels, thereby affecting the data transmission of other physical channels. To resolve the collision problem, the network can configure an uplink sending window (i.e., UL Window). During the uplink sending window, the terminal device only needs to send SRS and does not need to perform any other data transmission activities (receiving and sending).

[0192] It should be noted that the various technical solutions (or embodiments) of this application can be implemented independently or in combination based on certain internal connections. This application is not limited thereto. Furthermore, the various terms and definitions between the various embodiments can be referenced to each other. In each embodiment of this application, different implementations can also be implemented in combination or independently.

[0193] Please refer to FIG2a, which is a flowchart of a reference signal transmission method provided in an embodiment of the present application. As shown in FIG2a, the reference signal transmission method of this embodiment includes but is not limited to the following steps:

[0194] 101. A network device sends configuration information to a terminal device, and the terminal device receives the configuration information accordingly.

[0195] The configuration information is used to determine the time domain position of the uplink sending window. Exemplarily, the configuration information may be information configured by high-layer signaling.

[0196] 102. The terminal device determines an uplink sending window according to the configuration information.

[0197] 103. The terminal device sends an SRS in the uplink sending window. Correspondingly, the network device receives the SRS in the uplink sending window.

[0198] In some embodiments, if the SRS is transmitted periodically, the uplink transmission window may be periodic. Determining the uplink transmission window based on configuration information may refer to determining the time domain position of the periodic uplink transmission window. For example, the time domain position of the periodic uplink transmission window may be determined by determining the starting position of the periodic uplink transmission window (which may refer to the starting position of the first periodic uplink transmission window), the length of the uplink transmission window, and the period of the uplink transmission window. In the determined periodic uplink transmission window, the SRS is periodically transmitted based on the configuration of the SRS resources.

[0199] In some embodiments, if the SRS is transmitted non-periodically, the network device may trigger the transmission of the SRS on SRS resources in one or more SRS resource sets through DCI or MAC CE, where an SRS resource set includes multiple SRS resources. The terminal device may determine an uplink transmission window for transmitting the SRS on the triggered SRS resources based on the configuration information of the uplink transmission window.

[0200] The following examples illustrate several methods for determining the uplink send window:

[0201] Method 1: The uplink send window configuration information is configured for an SRS resource, or for an SRS resource set to which the SRS resource belongs. The configuration information indicates at least one of the following: a starting position of the uplink send window, a length of the uplink send window, and a period of the uplink send window. The terminal device may determine the uplink send window based on the configuration information.

[0202] In some embodiments, at least one of the starting position, period, and SRS resource time domain length (the time length from the starting position to the end position of an SRS resource) corresponding to different SRS resources may be different. For example, the number of symbols occupied by an SRS frequency hop of different SRS resources may be different, or the time interval between two adjacent SRS frequency hops in different SRS resources may be different, which will result in different time domain lengths corresponding to different SRS resources. In an embodiment of the present application, in order to ensure the utilization rate of the determined uplink sending window, as an example, the network device can configure an uplink sending window for the SRS resource, and the SRS resource is the time-frequency resource that carries the SRS in the uplink sending window. In other words, the configuration information of the uplink sending window is at the SRS resource level. The uplink sending window configuration information corresponding to different SRS resources may be different. As another example, the network device can configure an uplink sending window for an SRS resource set, and the SRS resource set is the SRS resource set to which the SRS resource that carries the SRS in the uplink sending window belongs. In other words, the configuration information of the uplink sending window is at the SRS resource set level.

[0203] For example, SRS can be sent periodically, and the uplink sending window can also be configured periodically. In method 1, the configuration information of the uplink sending window is configured for the SRS resource or the SRS resource set, which can specifically refer to the parameters of the uplink sending window configured for the SRS resource or the SRS resource set, for example, the starting position of the uplink sending window is configured (which can refer to the starting position of the first periodic uplink sending window), the length of the uplink sending window and the period of the uplink sending window, etc., so as to improve the utilization rate of the uplink sending window.

[0204] When sending SRS, the terminal device can determine the time domain position of the uplink sending window according to the configuration information corresponding to different SRS resources or different SRS resource sets, and then perform frequency hopping transmission of SRS. This makes the uplink sending window configuration more flexible, improves the utilization of the uplink sending window, and reduces the impact of the uplink sending window on other data transmissions. Other data transmissions may include but are not limited to the Physical Downlink Control Channel (PDCCH), Physical Downlink Shared Channel (PDSCH), Physical Uplink Shared Channel (PUSCH), Physical Uplink Shared Channel (PUCCH) and other reference signals.

[0205] Mode 2: The configuration information includes the length of the uplink sending window, and the DCI or MAC CE indicates the starting position of the uplink sending window. The terminal device can determine the uplink sending window based on the length of the uplink sending window and the starting position of the uplink sending window in the configuration information.

[0206] In some embodiments, for aperiodic SRS transmission, the network device may trigger SRS transmission on SRS resources in one or more SRS resource sets via DCI or MAC CE, where an SRS resource set may include multiple SRS resources. In some embodiments, the network device may indicate an uplink transmission window for SRS frequency hopping transmission via DCI or MAC CE.

[0207] Exemplarily, the DCI or MAC CE indicates the starting position of the uplink sending window, and the high-level signaling configures the length of the uplink sending window through configuration information. Specifically, optionally, the DCI or MAC CE may indicate a first offset, which is a time offset relative to the end position of the receiving resource of the DCI or MAC CE, wherein the end position of the receiving resource refers to the end position of the receiving resource time domain. As shown in Figure 2b, it is a schematic diagram of the first offset. As shown in Figure 2b, the starting position of the uplink sending window is the position determined by the first offset after the end position of the receiving resource of the DCI or MAC CE. Furthermore, the terminal device can determine the time domain position of the uplink sending window according to the length of the uplink sending window configured in the configuration information and the starting position of the uplink sending window.

[0208] In some implementations, the first offset may be an offset relative to the time unit where the DCI or MAC CE receiving resource ends, and the unit of the first offset may also be the time unit. The above-mentioned time unit may be a time domain unit such as a time slot, a radio frame, a subframe, a mini-slot, or at least one orthogonal frequency division multiplexing (OFDM) symbol. For example, taking the time unit as a time slot as an example, the terminal device determines the starting position of the uplink sending window based on the end slot of receiving the DCI or MAC CE and the time slot offset indicated by the DCI or MAC CE (i.e., how many time slots to offset), and then determines the time domain position of the uplink sending window based on the length of the uplink sending window configured by the network device. After the terminal device determines the uplink sending window, it sends the SRS in the uplink sending window according to the parameter configuration of the SRS resource in the SRS resource set triggered by the DCI or MAC CE. If some SRS resources in the SRS resource set triggered by DCI or MAC CE are not completely included in the uplink transmission window determined by the terminal device, the terminal device does not need to send SRS on these SRS resources. For example, if SRS resource 1 in the SRS resource set triggered by DCI or MAC CE is not completely included in the determined uplink transmission window, the terminal device may not send SRS on this SRS resource 1.

[0209] Mode 3: DCI or MAC CE indicates the starting position and length of the uplink sending window.

[0210] In some embodiments, the DCI or MAC CE may indicate the starting position of the uplink sending window and the length of the uplink sending window, and the terminal device may determine the time domain position of the uplink sending window based on the starting position of the uplink sending window and the length of the uplink sending window. The specific description of the DCI or MAC CE indicating the starting position of the uplink sending window can refer to the description of the aforementioned method 2 and will not be repeated here. In method 3, the DCI or MAC CE may also indicate the length of the uplink sending window. For example, the terminal device determines the starting position of the uplink sending window based on the end slot of receiving the DCI or MAC CE and the time slot offset (i.e., the number of time slots offset) indicated by the DCI or MAC CE, and then determines the time domain position of the uplink sending window based on the length of the uplink sending window indicated by the DCI or MAC CE. After determining the uplink sending window, the terminal device sends the SRS in the uplink sending window according to the parameter configuration of the SRS resource in the SRS resource set triggered by the DCI or MAC CE. If some SRS resources in the SRS resource set triggered by DCI or MAC CE are not completely included in the uplink transmission window determined by the terminal device, the terminal device does not need to send SRS on these SRS resources. For example, if SRS resource 1 in the SRS resource set triggered by DCI or MAC CE is not completely included in the determined uplink transmission window, the terminal device may not send SRS on this SRS resource 1.

[0211] In mode 4, the configuration information includes the length of the uplink send window. The terminal device determines the starting position of the uplink send window based on the time domain starting position of the first SRS resource, where the first SRS resource is the SRS resource with the earliest time domain starting position in at least one SRS resource set triggered by the DCI or MAC CE. The terminal device further determines the uplink send window based on the starting position of the uplink send window and the length of the uplink send window.

[0212] The time domain starting position of the first SRS resource is the SRS resource with the earliest time domain starting position in the at least one SRS resource set. In other words, the time domain starting position of any SRS resource other than the first SRS resource in the at least one SRS resource set is after the time domain starting position of the first SRS resource, or is the same as the time domain starting position of the first SRS resource. If there are multiple SRS resources with the same time domain starting position in the at least one SRS resource set, and the time domain starting position of the multiple SRS resources is the earliest, the first SRS resource may be one of the multiple SRS resources.

[0213] The terminal device can determine the starting position of the uplink sending window based on the time domain starting position of the first SRS resource. As an example, the time domain starting position of the first SRS resource is the starting position of the uplink sending window. As another example, the starting position of the uplink sending window is determined based on the time domain starting position of the first SRS resource and the second offset, and the second offset is the time offset before the time domain starting position of the first SRS resource. In other words, the starting position of the uplink sending window is the position determined by the second offset shifted forward from the time domain starting position of the first SRS resource. As shown in Figure 2c, it is a schematic diagram of the second offset. In this way, the length of the uplink sending window can be configured by high-level signaling through configuration information.

[0214] In some embodiments, the second offset may be configured by a network device, for example, via higher-layer signaling. The second offset may be an offset relative to the time unit where the time domain start position of the first SRS resource is located. The unit of the second offset may also be the time unit. For the definition of the time unit, please refer to the description of the aforementioned embodiment.

[0215] For example, the upper layer configures the length of the uplink sending window through configuration information, and the terminal device determines the starting position of the uplink sending window according to the time domain starting position of the first SRS resource with the earliest time domain starting position in at least one SRS resource set triggered by DCI or MAC CE. The terminal device can determine the time domain position of the uplink sending window according to the length of the uplink sending window configured by the upper layer. Optionally, the network device can configure an offset K, and the terminal device uses the time position of the time domain starting position of the first SRS resource in advance by K time units as the starting position of the uplink sending window. The definition of the time unit can refer to the description of the aforementioned embodiment and will not be repeated here. After the terminal device determines the uplink sending window, it sends the SRS in the uplink sending window according to the parameter configuration of the SRS resource in the SRS resource set triggered by DCI or MAC CE. If there are some SRS resources in the SRS resource set triggered by DCI or MAC CE that are not completely included in the uplink sending window determined by the terminal device, the terminal device does not need to send SRS on this part of the SRS resources.

[0216] Method 5, the configuration information may include a third offset and a fourth offset, the third offset is a time offset before the time domain starting position of the SRS resource, and the fourth offset is a time offset after the time domain ending position of the SRS resource. The starting position of the uplink sending window is determined according to the third offset and the time domain starting position of the SRS resource; the ending position of the uplink sending window is determined according to the fourth offset and the time domain ending position of the SRS resource, thereby determining the uplink sending window according to the starting position and the ending position.

[0217] In some embodiments, the network device may configure the third and fourth offsets via configuration information in higher-layer signaling. The third offset may be an offset before the time unit at which the time domain start position of the SRS resource is located, and the unit of the third offset may also be the time unit. The fourth offset may be an offset after the time unit at which the time domain end position of the SRS resource is located, and the unit of the fourth offset may also be a time unit. For the definition of time units, please refer to the description of the aforementioned embodiment.

[0218] The SRS resource may be a resource in an uplink transmission window used to carry an SRS. For example, the SRS resource may be an SRS resource in an SRS resource set triggered by a DCI or MAC CE, i.e., an SRS resource used for aperiodic SRS transmission, or an SRS resource configured for periodic transmission, which is not limited in this application.

[0219] FIG2d is a schematic diagram of the third and fourth offsets. As shown in FIG2d , the position determined by shifting the time domain start position of the SRS resource forward by the third offset is the start position of the uplink transmit window. The position determined by shifting the time domain end position of the SRS resource backward by the fourth offset is the end position of the uplink transmit window.

[0220] For example, the network device configures the third offset X and the fourth offset Y of the uplink send window. The terminal device determines the uplink send window based on the third offset X, the fourth offset Y, and the SRS resource. The terminal device transmits the SRS in the uplink send window based on the parameter configuration of the SRS resource. It is understood that the terminal device only transmits the SRS on the SRS resources included in the uplink send window.

[0221] Please refer to FIG3a, which is a flowchart of another reference signal transmission method provided in an embodiment of the present application. As shown in FIG3a, the reference signal transmission method of this embodiment includes but is not limited to the following steps. It is understandable that in a specific implementation, only some of the following steps may be included, and this application does not limit this. The following examples illustrate each step:

[0222] 201. The network device sends configuration information to the terminal device. Correspondingly, the terminal device receives the configuration information.

[0223] 202. The terminal device determines an uplink sending window according to the configuration information. The initial state of the uplink sending window is an activated state.

[0224] In an embodiment of the present application, the network device can configure a periodic uplink sending window through this configuration information. For example, this configuration information can be carried in higher-layer signaling, i.e., the periodic uplink sending window is configured through higher-layer signaling. The specific configuration method can refer to the description of the embodiment of FIG. 2a above and will not be repeated here. The initial state of the uplink sending window can be an activated state.

[0225] 203. The terminal device sends an SRS in the uplink sending window that is in the activated state. Correspondingly, the network device receives the SRS in the uplink sending window that is in the activated state.

[0226] In some embodiments, the uplink transmission window is a periodically configured uplink transmission window, and the terminal device may transmit the SRS in an activated periodic uplink transmission window. For example, if an uplink transmission window cannot completely contain an SRS frequency hopping pattern, the uplink transmission window may be considered invalid; the terminal device may transmit data in the invalid uplink transmission window. For example, the SRS may be transmitted periodically.

[0227] 204. The network device sends first indication information to the terminal device, where the first indication information is used to instruct deactivation of N consecutive uplink sending windows, where N is an integer greater than or equal to 1. Correspondingly, the terminal device receives the first indication information.

[0228] 205. The terminal device and the network device perform data transmission in the N consecutive deactivated uplink sending windows.

[0229] When the terminal device needs to perform data transmission, the network device may send a first indication message to the terminal device to indicate the deactivation of N consecutive uplink transmission windows. The first indication message may be carried in a DCI or a MAC CE. Exemplarily, the reception of the DCI or MAC CE may be used as a time reference point, and the N consecutive uplink transmission windows after the time reference point are all in a deactivated state. As shown in FIG3b , the N consecutive uplink transmission windows after the reception of the DCI or MAC CE are deactivated. The terminal device and the network device may perform data transmission in the deactivated N consecutive uplink transmission windows, and the data transmission may include but is not limited to: PDCCH, PDSCH, PUSCH, and PUCCH. This approach can minimize the impact on data transmission.

[0230] In one implementation, the value of N may be preconfigured, for example, the value of N may be configured via higher-layer signaling. The first indication information may be a deactivation indication, for example, a bit value. When the bit value is set to a first state value (e.g., the first state value is 1), it indicates deactivation of N consecutive uplink send windows. The terminal device deactivates N consecutive uplink send windows after receiving the first indication information. The terminal device may transmit data in the N consecutive deactivated uplink send windows.

[0231] In another implementation, the value of N may be one of a plurality of first candidate values, and the first indication information may include first numerical indication information, and the first numerical indication information is used to indicate the value of N. In some implementations, the first indication information may also include a deactivation indication, and the deactivation indication may be a bit value, and when the bit value is set to a first state value (for example, the first state value is 1), it indicates deactivation of the uplink sending window. In the embodiment of the present application, the first indication information may include first numerical indication information and / or deactivation indication. For example, the first indication information may only include the first numerical indication information, and the terminal device may determine that N consecutive uplink sending windows need to be deactivated after parsing the first numerical indication information. For another example, the first indication information may include the first numerical indication information and the deactivation indication, and the deactivation of N consecutive uplink sending windows is jointly indicated by the deactivation indication and the first numerical indication information.

[0232] Specifically, optionally, the DCI or MAC CE includes an indication field, which carries first numerical indication information for indicating the value of N. After the terminal device determines the value of N through the DCI, the time domain position of the DCI or MAC CE reception is used as the time reference point, and the N consecutive uplink sending windows after the time reference point are deactivated. The terminal device can transmit data in the deactivated uplink sending window.

[0233] In the embodiment of the present application, N consecutive uplink sending windows can be deactivated through the first indication information, and data transmission can be performed in the deactivated N consecutive uplink sending windows, thereby reducing the impact on data transmission.

[0234] Please refer to FIG4a, which is a flowchart of another reference signal transmission method provided in an embodiment of the present application. As shown in FIG4a, the reference signal transmission method of this embodiment includes but is not limited to the following steps. It is understandable that in a specific implementation, only some of the following steps may be included, and this application does not limit this. The following examples illustrate each step:

[0235] 301. The network device sends configuration information to the terminal device. Correspondingly, the terminal device receives the configuration information.

[0236] 302. The terminal device determines an uplink sending window according to configuration information. The initial state of the uplink sending window is an inactive state.

[0237] In an embodiment of the present application, a network device can configure a periodic uplink send window using this configuration information. For example, this configuration information can be carried in higher-layer signaling, i.e., the periodic uplink send window is configured via higher-layer signaling. The specific configuration method can refer to the description of the embodiment shown in FIG. 2a above and will not be further described here. The initial state of the uplink send window can be an inactive state. The inactive uplink send window can be used for data transmission between the terminal device and the network device.

[0238] 303. The network device sends second indication information to the terminal device, where the second indication information is used to indicate activation of M consecutive uplink sending windows, where M is an integer greater than or equal to 1. Correspondingly, the terminal device receives the second indication information.

[0239] 304. The terminal device sends SRS in M ​​consecutive activated uplink sending windows.

[0240] When the terminal device needs to send SRS, the network device sends a second indication message to the terminal device, and the second indication message is used to indicate the activation of M consecutive uplink sending windows. The second indication message can be carried in the DCI or MAC CE. Exemplarily, the time reference point of receiving the DCI or MAC CE can be used, and the M consecutive uplink sending windows after the time reference point are all in an activated state. As shown in Figure 4b, the M consecutive uplink sending windows after receiving the DCI or MAC CE are activated. The terminal device can send SRS in the activated M consecutive uplink sending windows. Exemplarily, the SRS can be sent non-periodically.

[0241] In one implementation, the value of M may be preconfigured, for example, the value of M may be configured via higher-layer signaling. The second indication information may be an activation indication, for example, a bit value. When the bit value is set to a first state value (e.g., the first state value is 1), it indicates activation of M consecutive uplink transmission windows. The terminal device activates M consecutive uplink transmission windows after receiving the second indication information. The terminal device may transmit an SRS in the activated M consecutive uplink transmission windows.

[0242] In another implementation, the value of M may be one of a plurality of second candidate values, and the second indication information may include second numerical indication information, and the second numerical indication information is used to indicate the value of M. In some implementations, the second indication information may also include an activation indication, and the activation indication may be a bit value. When the bit value is set to a first state value (for example, the first state value is 1), it indicates the activation of the uplink sending window. In the embodiment of the present application, the second indication information may include second numerical indication information and / or activation indication. For example, the second indication information may only include the second numerical indication information, and the terminal device may determine that M consecutive uplink sending windows need to be activated after parsing the second numerical indication information. For another example, the second indication information may include second numerical indication information and activation indication, and the activation indication and the second numerical indication information are jointly indicated to activate M consecutive uplink sending windows.

[0243] Specifically, the DCI or MAC CE contains an indication field, which carries second numerical indication information for indicating the value of M. After the terminal device determines the value of M through DCI, the DCI or MAC CE receiving time domain position is used as the time reference point, and the M consecutive uplink sending windows after the time reference point are activated. The terminal device can send SRS in the activated uplink sending window according to the SRS resource configuration.

[0244] If an uplink sending window cannot completely contain an SRS frequency hopping pattern, the uplink sending window may be considered invalid; the terminal device may perform data transmission in the invalid uplink sending window.

[0245] In an embodiment of the present application, the initial state of the uplink sending window is an inactive state. The network can activate M consecutive uplink sending windows through the second indication information, and send SRS in the activated M uplink sending windows, that is, the uplink sending window is activated when SRS needs to be sent, so that SRS is sent in the uplink sending window, which can improve the utilization rate of the uplink sending window and reduce the impact on data transmission, thereby reducing resource collisions.

[0246] Please refer to FIG5 , which is a flowchart of another reference signal transmission method provided in an embodiment of the present application. As shown in FIG5 , the reference signal transmission method of this embodiment includes but is not limited to the following steps. It is understandable that in a specific implementation, only some of the following steps may be included, and this application does not limit this. The following examples illustrate each step:

[0247] 401. The network device sends configuration information to the terminal device.

[0248] 402. The terminal device determines an uplink sending window according to the configuration information.

[0249] Among them, steps 401-402 of the embodiment of the present application can refer to steps 101-102 of the embodiment shown in Figure 2a.

[0250] 403 : In response to the uplink sending window overlapping with the measurement gap, send an SRS in the uplink sending window.

[0251] Alternatively, step 403 may be replaced by not sending the SRS in the uplink sending window in response to the uplink sending window and the measurement gap overlapping. That is, in response to the uplink sending window and the measurement gap not overlapping, sending the SRS in the uplink sending window.

[0252] For Radio Resource Management (RRM) measurements, the network will configure periodic Measurement Gaps (MG) to the terminal device for RRM measurements, including the starting position of the measurement gap, the period, and the length of the measurement gap. The terminal device only performs relevant measurement activities during the measurement gap period and does not perform any other data transmission and reference signal sending activities. After the uplink sending window is introduced in the embodiment of the present application, there may be overlap (or collision) between the uplink sending window and the MG in the time domain. The following example illustrates the implementation method when the uplink sending window overlaps with the MG. It can be understood that the following "in response to the uplink sending window overlapping with the MG" can be replaced with "when the uplink sending window overlaps with the MG", or replaced with "when the uplink sending window overlaps with the MG".

[0253] In one implementation, in response to an overlap between the uplink sending window and the MG, the uplink sending window is disabled, i.e., the terminal device does not send an SRS in the uplink sending window but performs RRM measurements in the MG. Further, optionally, when the uplink sending window does not overlap with the MG, the terminal device sends an SRS in the uplink sending window.

[0254] In another implementation, in response to an overlap between an uplink sending window and an MG, the MG fails, and the terminal device may send an SRS in the uplink sending window.

[0255] In another implementation, in response to an uplink sending window overlapping with the MG and satisfying a first condition, the terminal device sends an SRS in the uplink sending window. Exemplarily, the first condition includes at least one of the following: a priority of an SRS resource used to carry the SRS is greater than or equal to a first threshold; and a priority of the uplink sending window is greater than or equal to a second threshold.

[0256] In another implementation, in response to an overlap between the uplink sending window and the MG and the first condition not being met, the terminal device performs RRM measurements in the MG. For example, if the uplink sending window overlaps with the MG and the priority of the SRS resource used to carry the SRS is less than a first threshold, the terminal device does not send the SRS in the uplink sending window but performs RRM measurements in the MG. For another example, if the uplink sending window overlaps with the MG and the priority of the uplink sending window is less than a second threshold, the terminal device does not send the SRS in the uplink sending window but performs RRM measurements in the MG.

[0257] Exemplarily, the priority of the SRS resource used to carry SRS is greater than or equal to the first threshold, which may mean that the priority of the SRS resource used to send SRS in the uplink sending window is greater than or equal to the first threshold, the MG fails, and the terminal device can send SRS in the uplink sending window. If the priority of the SRS resource is less than the first threshold, the uplink sending window fails, and the terminal device can use the MG to perform RRM measurements.

[0258] Exemplarily, the network device may be configured with multiple sets of configuration information for uplink sending windows, each set of configuration information for uplink sending windows may correspond to a priority, and the priorities of different sets of configuration information for uplink sending windows may be different. The terminal device may determine the uplink sending window based on one set of configuration information for uplink sending windows. For ease of description, the priority corresponding to the configuration information for determining the uplink sending window is referred to as the priority of the uplink sending window. If the uplink sending window overlaps with the MG, and the priority of the uplink sending window is greater than or equal to the second threshold, the MG fails, and the terminal device may send SRS in the uplink sending window. If the priority of the uplink sending window is less than the second threshold, the uplink sending window fails, and the terminal device performs RRM measurements in the MG.

[0259] In the embodiments of the present application, for the scenario where the uplink sending window and the measurement gap overlap, the present application proposes multiple solutions to ensure SRS transmission or RRM measurement.

[0322] Please refer to Figure 8, which is a structural diagram of another communication device provided in an embodiment of the present application, which is used to implement the functions of the terminal devices in Figures 2a, 3a, 4a and 5 above, or to implement the functions of the network devices in Figures 2a, 3a, 4a and 5 above. The communication device 300 can be a terminal device or a device for a terminal device. The device for a terminal device can be a chip system or chip in a terminal device. The communication device can also be a network device or a device for a network device. The device for a network device can be a chip system or chip in a network device. Among them, the chip system can be composed of chips, or it can include chips and other discrete devices.

[0323] The communication device 300 includes at least one processor 320 for implementing the data processing function of the terminal device in the method provided in the embodiment of the present application. The communication device 300 may also include a communication interface 310 for implementing the transceiver operation of the terminal device in the method provided in the embodiment of the present application. In the embodiment of the present application, the processor 320 may be a central processing unit (CPU), and the processor may also be other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gates or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or the processor may also be any conventional processor, etc. In the embodiment of the present application, the communication interface 310 may be a transceiver, circuit, bus, module or other type of communication interface for communicating with other devices via a transmission medium. For example, the communication interface 310 is used for the communication device 300 to communicate with other devices. The processor 320 uses the communication interface 310 to send and receive data, and is used to implement the methods described in the above method embodiments FIG. 2 a , FIG. 3 a , FIG. 4 a and FIG. 5 .

[0324] The communication device 300 may also include at least one memory 330 for storing program instructions and / or data. The memory 330 is coupled to the processor 320.

The processor 320 may operate in conjunction with the memory 330. The processor 320 may execute program instructions stored in the memory 330. At least one of the at least one memory may be included in the processor.

[0325] When the communication device 300 is turned on, the processor 320 can read the software program in the memory 330, interpret and execute the instructions of the software program, and process the data of the software program. When data needs to be sent wirelessly, the processor 320 performs baseband processing on the data to be sent and outputs the baseband signal to the radio frequency circuit (not shown in Figure 8). The radio frequency circuit performs radio frequency processing on the baseband signal and then transmits the radio frequency signal to the outside in the form of electromagnetic waves through the antenna. When data is sent to the communication device 300, the radio frequency circuit receives the radio frequency signal through the antenna, converts the radio frequency signal into a baseband signal, and outputs the baseband signal to the processor 320. The processor 320 converts the baseband signal into data and processes the data.

[0326] In another implementation, the RF circuit and antenna may be provided independently of the processor 320 that performs baseband processing. For example, in a distributed scenario, the RF circuit and antenna may be remotely located independent of the device.

[0327] The specific connection medium between the communication interface 310, processor 320, and memory 330 is not limited in the embodiments of the present application.

The connection method between other components is only for schematic illustration and is not limiting. The bus can be divided into an address bus, a data bus, a control bus, etc. For ease of representation, only one bold line is used in Figure 8, but this does not mean that there is only one bus or one type of bus.

[0328] When the communication device 300 is specifically used in a terminal device, for example, when the communication device 300 is specifically a chip or a chip system, the communication interface 310 may output or receive a baseband signal. When the communication device 300 is specifically a terminal device, the communication interface 310 may output or receive a radio frequency signal.

[0329] It should be noted that the communication device 300 can execute the relevant steps of the terminal device in the aforementioned method embodiment. For details, please refer to the implementation methods provided in the above steps, which will not be repeated here.

Alternatively, at least some of the modules can be implemented by software programs, which run on a processor integrated within the terminal, and the remaining (if any) modules can be implemented by hardware such as circuits.
