[0002] In the research of the Rel-17 DSS project, a temporary reference signal (TRS) was defined to accelerate the activation / deactivation process of secondary cells (SCells). The base station triggers the transmission of the TRS during SCell activation through the Media Access Control (MAC) Control Element (CE).

[0003] The terminal performs Automatic Gain Control (AGC) adjustments and / or Time (T) / Frequency (F) tracking based on temporary reference signals, thereby avoiding waiting for the synchronization signal block (SSB) based Radio Resource Management (SRM) measurement timing configuration (SMTC) period to perform the aforementioned operations. According to RAN1, the temporary reference signal multiplexes the time-frequency domain structure of the current tracking reference signal (TRS), meaning that a temporary reference signal cluster contains four Orthogonal Frequency Division Multiplexing (OFDM) symbols across two consecutive time slots.

As shown in Figure 1 , the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system can include a plurality of UEs 11 and a plurality of access devices 12.

[0034] The UE 11 can be a device that provides voice and / or data connectivity to a user. The UE 11 can be a machine-to-machine UE, such as a sensor device, a mobile telephone (also known as a "cellular" telephone), and a computer with a machine-to-machine UE, e.g., a fixed, portable, pocket, handheld, computer-embedded, or car-mounted device.

In different embodiments, the wireless air interface is a wireless air interface based on a fourth generation mobile communication network technology (4G) standard; or the wireless air interface is a wireless air interface based on a fifth generation mobile communication network technology (5G) standard, such as a new air interface; or the wireless air interface can also be a wireless air interface based on a more next generation mobile communication network technology standard of 5G.

[0038] In some embodiments, the UEs 11 can also establish an E2E (End to End) connection. For example, V2V (vehicle to vehicle) communication, V2I (vehicle to infrastructure) communication, and V2P (vehicle to pedestrian) communication in vehicle to everything (V2X) communication and the like.

[0039] In some embodiments, the wireless communication system described above can also include a network management device 13.

[0040] A plurality of access devices 12 are respectively connected with a network management device 13. The network management device 13 can be a core network device in a wireless communication system, for example, the network management device 13 can be a Mobility Management Entity (MME) in an Evolved Packet Core (EPC). Alternatively, the network management device can also be other core network devices, such as a Serving GateWay (SGW), a Public Data Network GateWay (PGW), a Policy and Charging Rules Function (PCRF), or a Home Subscriber Server (HSS), etc. The implementation form of the network management device 13 is not limited in the embodiments of the present disclosure.

[0041] As shown in Figure 2 The embodiments of the present disclosure provide a processing method of a temporary reference signal cluster, which is executed by a terminal, and the method comprises:

[0042] S110: When it is determined according to the network side configuration that the transmission resource of the temporary reference signal cluster conflicts with the unavailable resource, determining the time interval between two adjacent transmission temporary reference signal clusters.

[0043] The terminal can be any type of terminal, for example, a mobile phone, a tablet computer, a wearable device, a vehicle-mounted device, a smart home device, and / or a smart office device, etc. The terminal can be a terminal supporting dual connectivity, for example, the terminal can be connected to a secondary cell in addition to a primary cell.

[0044] The network side at least includes a network side of an access network, and the network device of the access network can include a base station.

[0045] The base station can pre-send configuration information of the transmission resource of the temporary reference signal cluster through RRC signaling or the like, and the configuration information is the aforementioned network side configuration, that is, the network side configuration is an RRC configuration. In this way, the terminal can determine the transmission resource of the temporary reference signal cluster according to the RRC signaling.

[0046] Of course, the aforementioned network side configuration includes but is not limited to the configuration information sent through the RRC signaling.

[0047] The unavailable resource is any communication resource that the terminal cannot use for transmission of the temporary reference signal cluster, including but not limited to at least one of the following:

[0048] An uplink (UL) symbol in a time slot structure of a Time Division Duplex (TDD) cell;

[0049] A special time slot in a time slot structure of a Time Division Duplex (TDD) cell;

[0050] A network-side configured reserved resource; the reserved resource includes but is not limited to a resource for future expansion of a communication system;

[0051] A resource for transmitting a Cell Reference Signal (CRS) in a New Radio (NR) and Long Term Evolution (LTE) coexistence scenario.

[0052] Before receiving a temporary reference signal cluster, the terminal determines, according to a network-side configuration, a time-frequency domain resource (i.e., the aforementioned transmission resource) for receiving the temporary reference signal cluster and a time interval between two adjacent transmission temporary signal clusters when the transmission resource conflicts with an unavailable resource.

[0053] In this way, by determining the time interval, the transmission quality of the temporary reference signal cluster can be ensured through the time interval. For example, according to the discussion of Radio Access Network (RAN) 4, when the terminal needs to perform AGC setting and T / F tracking according to two temporary reference signal clusters in this scenario, a sufficient time interval is provided between the two temporary reference signal clusters, thereby ensuring the reception quality of the terminal for the temporary reference signal.

[0054] As shown in FIG. 1, the embodiments of the present disclosure provide a processing method of a temporary reference signal cluster, which is executed by a terminal and can include: Figure 3A S110A: When it is determined, according to a network-side configuration, that the transmission resource of the temporary reference signal cluster conflicts with an unavailable resource, determining, according to a predefined rule, a time interval between two adjacent transmission temporary reference signal clusters.

[0055] As shown in FIG. 2, the embodiments of the present disclosure provide a processing method of a temporary reference signal cluster, which is executed by a terminal and can include:

[0056] Figure 3B S110B: When it is determined, according to a network-side configuration, that the transmission resource of the temporary reference signal cluster conflicts with an unavailable resource, determining, according to a base station indication, a time interval between two adjacent transmission temporary reference signal clusters.

[0057] S110B: When it is determined, according to a network-side configuration, that the transmission resource of the temporary reference signal cluster conflicts with an unavailable resource, determining, according to a base station indication, a time interval between two adjacent transmission temporary reference signal clusters. ​

[0058] The predefined rules can be pre-agreed upon by the base station and the terminal; or communication rules; or rules pre-specified by the communication operator, etc.

[0059] There can be multiple predefined rules, and they are not limited to any one of the above.

[0060] In some embodiments, the specific value of the time interval can be indicated by the base station. Thus, the terminal can determine the time interval between two adjacent temporary reference signal clusters by receiving base station signaling from the base station.

[0061] The base station signaling sent by the base station can explicitly or implicitly indicate the time interval between two adjacent temporary reference signal clusters.

[0062] In one embodiment, if the terminal receives base station signaling indicating the time interval, it determines the time interval between two adjacent temporary reference signal clusters based on the base station signaling. If the terminal does not receive base station signaling indicating the time interval, it determines the time interval between two adjacent temporary reference signal clusters automatically according to predefined rules.

[0063] In one embodiment, determining the time interval between two adjacent temporary reference signal clusters according to predefined rules includes: determining the time interval between two adjacent temporary reference signal clusters according to the minimum time interval between two adjacent temporary reference signal clusters specified in the RAN4 protocol and the duplex mode of the terminal operation.

[0064] That is, predefined rules include, but are not limited to, the RAN4 protocol.

[0065] RAN4 protocol is a communication standard protocol. In the embodiments of this disclosure, when determining the time interval, in order to determine a suitable time interval, the minimum time interval between two adjacent temporary reference signal clusters of transmission as specified in the RAN4 protocol and the current duplex mode of the terminal are used to determine the time interval between two adjacent temporary reference signal clusters of transmission that is suitable for the current duplex mode of the terminal. This ensures that the determined time interval is sufficient to ensure that the terminal has enough time to receive each temporary reference signal cluster, thereby ensuring reception quality.

[0066] In one embodiment, determining the time interval between two adjacent temporary reference signal clusters based on the minimum time interval between two adjacent temporary reference signal clusters specified in the RAN4 protocol and the duplex mode of the terminal operation includes:

[0067] The duplex mode of the terminal is a Frequency Division Duplexing (FDD) duplex mode, and the time interval between the two temporary reference signal clusters of adjacent transmission is determined as a first time interval;

[0068] Or,

[0069] The duplex mode of the terminal is a TDD duplex mode, and according to a TDD uplink-downlink time slot structure, the time interval between the two temporary reference signal clusters of adjacent transmission is determined as a maximum value between a first time interval and a second time interval;

[0070] The first time interval is a minimum time interval between adjacent temporary reference signal clusters specified in a wireless access network RAN4 protocol;

[0071] The second time interval is a time interval between two non-continuous downlink time slots of the TDD frequency band, or a time interval between two non-continuous downlink symbols.

[0072] In the following embodiments, the first time interval can be represented by the letter G; and the second time interval can be represented by the letter L.

[0073] If the current duplex mode of the terminal is an FDD duplex mode, that is, the uplink and downlink of the terminal use different frequency points, then the uplink time slots and the downlink time slots of the terminal are distributed on different frequency points and do not interfere with each other. At this time, the minimum time interval specified in the RAN4 protocol can be directly used as the time interval between the two temporary reference signal clusters of adjacent transmission. Of course, in some embodiments, the time interval between the two temporary reference signal clusters of adjacent transmission can also be set to be slightly greater than G according to the terminal type, for example, a*G, where a is any positive integer greater than 1 and less than 2.

[0074] In another embodiment, if the terminal works in a TDD duplex mode, then the uplink time slots, the downlink time slots, and the special time slots of the TDD cell are located on the same frequency point. At this time, it needs to be considered that the uplink time slots and / or the special time slots cannot be used for the transmission of the temporary reference signal cluster. In combination with the minimum time interval (i.e., G) required by the terminal and the larger value between the time interval between two non-continuous downlink time slots or the time interval between two non-continuous downlink symbols of the TDD frequency band, the time interval between the two temporary reference signal clusters of adjacent transmission is determined. The time interval between the two temporary reference signal clusters of adjacent transmission determined in this way not only considers the time required by the terminal to process the two temporary reference signal clusters, but also takes into account the time slot structure under the TDD duplex mode.

[0075] In some embodiments, the determining the time interval between the two temporary reference signal clusters of adjacent transmission according to the base station indication comprises at least one of:

[0076] determining the time interval between the two temporary reference signal clusters of adjacent transmission according to interval indication information contained in the base station signaling; wherein the interval indication information indicates the time interval; or,

[0077] determining the time interval between the two temporary reference signal clusters of adjacent transmission according to a correspondence between the base station signaling and a time interval value.

[0078] In some embodiments, the base station signaling directly comprises interval indication information occupying one or more bits. In this way, the terminal can directly determine the time interval between the two temporary reference signal clusters of adjacent transmission according to the interval indication information carried by the base station signaling.

[0079] In other embodiments, the base station signaling itself does not carry interval indication information, but the information content carried by the base station signaling or the transmission parameters of the base station signaling have a correspondence with the time interval value of the time interval. The transmission parameters include but are not limited to: transmission resource, base station signaling format and / or base station signaling type. For example, different base station signaling formats have different lengths and / or internal structures of the base station signaling. The type of base station signaling can be determined according to the corresponding network layer, such as MAC layer signaling, RRC signaling and / or physical layer signaling, etc.

[0080] In this way, after receiving the base station signaling having a correspondence with the time interval value, the terminal determines the time interval value corresponding to the received base station signaling as the time interval between the two temporary reference signal clusters of adjacent transmission according to the correspondence between the signaling content of the base station signaling and the time interval value, or the correspondence between the transmission parameters of the base station signaling and the time interval value.

[0081] The transmission parameters can include: transmission resource location, scrambling sequence used in transmission, transmission format of the base station signaling, modulation and coding scheme (MCS) of the base station signaling.

[0082] If implicit indication of the base station signaling is used, i.e. no special bits are occupied in the base station signaling to implicitly indicate the time interval value.

[0083] In one embodiment, the base station signaling comprises at least one of:

[0084] downlink control information (DCI);

[0085] or,

[0086] MAC CE.

[0087] DCI stands for Physical Layer Signaling, which is characterized by its high dynamism.

[0088] MAC CE is MAC layer signaling, which carries more flexible content than DCI and is more dynamic than RRC signaling.

[0089] By leveraging the dynamic characteristics of DCI and / or MAC CE, time intervals can be quickly indicated to the terminal.

[0090] In one embodiment, the DCI is: the DCI of the downlink control shared channel (PDSCH) of the MAC CE activated by the secondary cell scheduling.

[0091] If the DCI of the PDSCH of the MAC CE activated by the secondary cell is used, then while scheduling the transmission resources of the MAC CE of the activated secondary cell, the time interval between the two temporary reference signal clusters of the aforementioned adjacent transmissions is indicated. In this way, when the transmission resources of the temporary reference signal clusters used for the activated secondary cell conflict with other unavailable resources, the time interval is known in advance directly from the DCI, without having to wait for base station signaling to determine it.

[0092] The DCI of the downlink control shared channel (PDSCH) of the MAC CE activated by the secondary cell here includes: resource information indicating the transmission of the PDSCH of the MAC CE activated by the secondary cell.

[0093] In one embodiment, the MAC CE carries the interval indication information;

[0094] or,

[0095] The temporary reference signal triggering information carried by the MAC CE implicitly indicates the time interval.

[0096] If a MAC CE is used to indicate the time interval, it can be explicitly indicated by the interval indication information carried by the MAC CE, or implicitly indicated by the temporary reference signal information carried by the MAC CE.

[0097] The temporary reference signal triggering information may include a triggering command to trigger the transmission of a temporary reference signal cluster. At this time, while triggering the transmission of the temporary reference signal cluster, the MAC CE indicates that if the transmission resources of the temporary reference signal cluster conflict with unavailable resources, the terminal will receive two adjacent temporary reference signal clusters transmitted by the base station based on the time interval corresponding to the temporary reference signal triggering information of the temporary reference signal cluster.

[0098] In one embodiment, the temporary reference signal triggering information is used to determine relevant information of the temporary reference signal, wherein the relevant information is pre-configured by RRC signaling and includes: interval indication information indicating the time interval.

[0099] For example, before MAC CE transmission, the base station may pre-send RRC signaling, which pre-configures the transmission of temporary reference signal clusters. For instance, this RRC signaling may pre-configure interval indication information for one or more time intervals. There can be multiple types of temporary reference signal triggering information; different types of triggering information will trigger the terminal to receive the temporary reference signal. Simultaneously, based on the relevant information corresponding to the temporary reference signal triggering information, the interval indication information carried in the RRC signaling will be obtained, and ultimately, the transmission interval between two adjacent temporary reference signal clusters will be determined.

[0100] If the aforementioned base station signaling is DCI, then the DCI carries interval indication information, wherein the interval indication information indicates the value of the time interval;

[0101] The time interval indicated by the interval indication information is either a value located in the set of values ​​configured in the Radio Resource Control (RRC) signaling configuration, or a value located in a set of values ​​predefined by the protocol.

[0102] For example, a DCI can carry a bitmap where each bit indicates a value. This value can be carried in RRC signaling that configures the transmission of temporary reference signal clusters.

[0103] For example, the DCI contains an indication value, and different indication values ​​correspond to different time interval values. In this way, after receiving the DCI, the terminal can know the time interval between two adjacent temporary reference signal clusters indicated by the base station.

[0104] like Figure 4 As shown, this disclosure provides a method for processing temporary reference signal clusters, wherein the method is executed by a base station, and the method includes:

[0105] S210: When it is determined from the network side configuration that the transmission resources of the temporary reference signal cluster conflict with the unavailable resources, determine the time interval between two adjacent temporary reference signal clusters.

[0106] The method for processing temporary reference signal clusters provided in this disclosure is applied in a base station on the network side. The method may include: when it is determined, based on a determined or issued network configuration, that the transmission resources of a temporary reference signal cluster conflict with unavailable resources, determining the time interval between two adjacent temporary reference signal clusters.

[0107] Thus, when the subsequent base station transmits the temporary reference signal cluster according to the determined time interval, the terminal has sufficient time interval to process the temporary reference cluster after the adjacent transmission of the previous temporary reference cluster, and sufficient preparation time to receive the temporary reference signal cluster after the adjacent transmission of the next temporary reference cluster, so as to ensure that both temporary reference signal clusters of the adjacent transmission can be successfully transmitted, and the transmission success rate of the temporary reference signal cluster is improved.

[0108] In some embodiments, the S210 can include:

[0109] When it is determined according to the network side configuration that the transmission resource of the temporary reference signal cluster conflicts with the unavailable resource, the time interval between the two temporary reference signal clusters of the adjacent transmission is determined according to the predefined rule.

[0110] The base station can determine the time interval between the two temporary reference signal clusters of the adjacent transmission according to the predefinition. The predefinition can be predefined by the base station itself, or determined based on the pre-configuration received from the network management device or other upper layer device, or predefined by the communication protocol.

[0111] Of course, the above is only an example, and there are many ways of predefinition, not limited to any of the above.

[0112] As shown in FIG. 1, Figure 5 The present disclosure provides a processing method of temporary reference signal cluster, which can include:

[0113] S220: When it is determined according to the network configuration that the transmission resource of the temporary reference signal cluster conflicts with the unavailable resource, the time interval between the two temporary reference signal clusters of the adjacent transmission is indicated.

[0114] In some embodiments, the time interval can be the time interval determined in the foregoing step S210, or can be pre-determined by the base station or received from the network management device or other upper layer device.

[0115] In summary, after the base station determines the time interval, the base station indicates the time interval to the terminal. The indication method of the base station can be explicit indication or implicit indication. The base station indicates the time interval determined by itself to the terminal, and the terminal will receive the temporary reference signal cluster according to the time interval.

[0116] In some embodiments, the S220 can include:

[0117] The interval indication information for explicitly indicating the time interval is transmitted.

[0118] The interval indication information for linearly indicating the time interval, and the interval indication information alone occupies at least one or more bits, and the bit value of the bits is used to indicate the value of the time interval.

[0119] If the base station explicitly indicates the time interval through interval indication information, signaling carrying the interval indication information is sent.

[0120] Exemplarily, the interval indication information is carried in DCI or MAC CE.

[0121] The interval indication information can be carried in DCI or MAC CE with good dynamics, so that the terminal can receive the time interval indicated by the base station in time.

[0122] In some embodiments, the DCI includes: DCI of a downlink control shared channel PDSCH scheduling a MAC CE for activating a secondary cell.

[0123] The interval indication information is carried in the DCI scheduling the PDSCH of the MAC CE for activation, so that the terminal can directly know the time interval between two adjacent transmission temporary reference signal clusters for AGC adjustment and / or T / F tracking according to the DCI.

[0124] In some embodiments, the MAC CE carrying the temporary reference signal triggering information implicitly indicates the time interval. Such MAC CE does not directly indicate the time interval, but implicitly indicates the time interval. For example, the MAC CE triggering the transmission of the temporary reference signal cluster is used to indicate the time interval.

[0125] In some embodiments, the MAC CE carries the interval indication information.

[0126] In some embodiments, the temporary reference signal triggering information is used for the terminal to determine the related information of the temporary reference signal, wherein the related information is information pre-configured by RRC signaling. The related information includes the time interval information.

[0127] The related information is pre-sent to the terminal through RRC signaling (i.e., pre-configured by RRC signaling), so that the terminal pre-receives the related information based on the RRC signaling, and then determines the related information according to the MAC CE after receiving the MAC CE carrying the temporary reference signal triggering information, and finally determines the time interval based on the related information.

[0128] In some embodiments, the time interval between two adjacent transmission temporary reference signal clusters is determined according to a pre-defined rule, including:

[0129] The minimum time interval between two adjacent temporary reference signal clusters and the duplex mode of the terminal are determined according to the RAN4 protocol, and the time interval between two adjacent transmission temporary reference signal clusters is determined.

[0130] In some embodiments, the minimum time interval between two adjacent temporary reference signal bursts as specified in the RAN4 protocol and the duplex mode in which the terminal is currently operating are used to determine the time interval between two adjacent temporary reference signal bursts.

[0131] When the duplex mode of the terminal is frequency division duplex (FDD), the time interval between two adjacent temporary reference signal bursts is determined to be a first time interval.

[0132] Alternatively,

[0133] When the duplex mode of the terminal is time division duplex (TDD), the time interval between two adjacent temporary reference signal bursts is determined to be the maximum of a first time interval and a second time interval according to the TDD uplink / downlink slot structure.

[0134] The first time interval is the minimum time interval between two adjacent temporary reference signal bursts as specified in the RAN4 protocol.

[0135] The second time interval is the time interval between two non-continuous downlink slots or the time interval between two non-continuous downlink symbols in the TDD frequency band.

[0136] Similarly, the base station determines the time interval between two adjacent temporary reference signal bursts by referring to the RAN4 protocol and the duplex mode in which the terminal is currently operating.

[0137] In other embodiments, in addition to referring to the minimum time interval specified in the RAN4 protocol and the duplex mode in which the terminal is currently operating, the base station can also determine the time interval between two adjacent temporary reference signal bursts according to the capability of the terminal.

[0138] A reference signal burst (RS burst) of a tracking reference signal (TRS) contains one or two consecutive slots, and each slot contains two temporary RS samples. The time-frequency domain transmission resource of the TRS in a slot is configured by RRC.

[0139] For example, in FR1, the pattern in a reference signal burst can be as shown in Figure 6 The resource element (RE) density of the TRS is fixed, and single-port transmission is used.

[0140] ReferenceFigure 6 As shown, one TRS burst spans two slots in time domain. Two TRS symbols in one TRS burst are transmitted in slot n, and two TRS symbols in one TRS burst are transmitted in slot n+1.

[0141] The network side indicates the time interval (GAP) between two temporary RS bursts to the terminal through explicit signaling or implicit manner.

[0142] There are multiple ways to determine the time interval, and several optional ways are provided as follows:

[0143] Optional way 1: The terminal side determines the time interval between two temporary RS bursts according to a predefined rule.

[0144] The terminal determines the time interval between two temporary RS bursts according to the minimum time interval between temporary RS bursts defined by the RAN4 protocol and the uplink-downlink slot ratio.

[0145] If the current frequency band is an FDD frequency band, the time interval between the two temporary RS bursts is the minimum value G defined by the RAN4 protocol.

[0146] The G is a number of slots or a number of ms.

[0147] If the current frequency band is a TDD frequency band, the time interval between the two temporary RS bursts is max(G, L).

[0148] Wherein, L is the time interval between two non-continuous DL slots or DL symbols in time domain.

[0149] Optional way 2: The terminal side determines the time interval between two temporary RS bursts according to the indication signaling sent by the base station

[0150] Way 2.1: The terminal determines the specific value of the time interval according to the interval indication information carried in the DCI by the base station.

[0151] The DCI is the DCI scheduling the PDSCH carrying the secondary cell activation (SCell activation) MAC CE.

[0152] The interval indication information carried in the DCI is a value set configured by RRC signaling, which includes one or more alternative values of time intervals. The MAC CE can carry the serial number of the value of the time interval that takes effect finally. Of course, this is only an example, and the specific implementation is not limited thereto.

[0153] Alternatively, the interval indication information carried in the DCI is a protocol pre-defined value set, which has one or more values of time intervals. Mode 2-2: The terminal determines the specific value of the time interval according to the interval indication information carried in the MAC CE triggering the temporary RS by the base station. The MAC CE triggering the temporary RS can be the MAC CE triggering the transmission of the temporary RS.

[0154] The time interval between the temporary RS bursts is indicated by the explicit bit carried in the MAC CE.

[0155] Alternatively, the time interval between the temporary RS bursts is indicated implicitly by the temporary RS triggering information carried in the MAC CE

[0156] The terminal obtains the triggered temporary RS related information through the temporary RS triggering information, and the related information includes the time interval information between the temporary RS bursts.

[0157] The temporary RS related information is configured by RRC signaling.

[0158] For the network side, determining the transmission interval of two adjacent temporary RS bursts can include:

[0159] The network side determines the time interval between the two temporary RS bursts according to a pre-defined rule.

[0160] The network side indicates the terminal the time interval between the two temporary RS bursts according to the indication signaling sent by the base station.

[0161] Assume that the cell is a TDD cell, and the network side configures a TDD uplink (UL) downlink (DL) configuration through a system information block (SIB) or UE dedicated RRC signaling. In this embodiment, assume that the TDD UL DL configuration configured by the network side is a single period, and the specific time slot structure is DDUU, and the SCS is 15 kHz. D represents a downlink time slot, U represents an uplink time slot, and S represents a special time slot. As shown in FIG. 1, it is a time slot structure of a TDD cell. Figure 7

[0162] Assume that the uplink and downlink time slot structure of the special (S) time slot is 7D 3F 4U, that is, it contains 7 DL symbols, 3 flexible symbols, and 4 UL symbols.

[0163] Assume that the temporary RS triggered by the network side for SCell activation contains two bursts, each burst contains 4 temporary RS samples on two consecutive DL time slots, and the time interval between the two bursts defined by the RAN4 protocol is 2 time slots. In this embodiment, assume that the pattern of the temporary RS burst can be as shown in FIG. 2, which occupies m resource blocks (RBs) in the frequency domain, and occupies two OFDM symbols #4 and #8 in each time slot. Figure 8

[0164] Figure 8 The s th TRS burst and the s+1 th TRS burst in FIG. 3 are one of the aforementioned temporary RS bursts. As shown in FIG. 4, one TRS is transmitted every 3 REs in RB#n to RB#n+m-1. Figure 8 Figure 8 The transmission resource is shown in FIG. 5, where the horizontal axis is the time axis and the vertical axis is the frequency axis.

[0165] The interval between the s th TRS burst and the s+1 th TRS burst is 2 time slots.

[0166] The TRS burst here is one of the aforementioned temporary RS bursts, but the temporary RS burst is not limited to the TRS burst.

[0167] ​​​Assuming that the base station indicates that the temporary reference signal burst starts transmission at time slot #0, the base station ensures that the n th temporary reference signal burst and the (n+1) th temporary reference signal burst can be successfully transmitted on the downlink resource in the following manner.

[0168] The base station and the terminal determine the actual time interval between the two temporary reference signal bursts during transmission according to the minimum time interval between the temporary reference signal bursts defined by the RAN4 protocol and the time interval between the discontinuous DL time slots. Exemplarily, in the embodiment, the minimum time interval between the temporary reference signal bursts defined by the RAN4 protocol is G=2 time slots, the time interval between the discontinuous DL time slots is L=3 time slots, and the actual time interval between the two temporary reference signal bursts during transmission is max(G, L)=3 time slots.

[0169] The actual time-frequency domain position of the temporary reference signal burst can refer to Figure 9 The actual time-frequency domain position of the temporary reference signal burst can refer to

[0170] It should be noted that the minimum interval between the two temporary reference signal bursts defined by the RAN4 protocol can also be defined in ms. In this case, the m seconds should be converted into the number of time slots according to the subcarrier spacing (SCS) of the bandwidth part (BWP) in which the temporary RS is transmitted, and then the minimum time interval between the two temporary reference signal bursts is determined by the above method.

[0171] Assuming that the cell is an FDD cell, the minimum time interval between the two temporary reference signal bursts is determined by the minimum value defined by the RAN4 protocol, for example, 2 time slots or the number of time slots contained in 2 ms.

[0172] It is assumed that two temporary RS bursts are triggered by the network side for AGC settling and T / F tracking, respectively. The base station indicates the time interval between the two temporary RS bursts triggered by the base station through the interval indication information carried in the DCI scheduling the PDSCH carrying the SCell activation MAC CE and / or temporary RS triggering. Exemplarily, the network side indicates the time interval between the temporary RS bursts through the N-bit interval indication information carried in the DCI.

[0173] In the embodiment, it is assumed that N = 2.

[0174] Reference Figure 10 As shown, the two bits of interval indication information are carried by the DCI, and then the time interval between the two adjacent transmitted temporary RS bursts is explicitly indicated. Figure 10 The time interval indicated by the interval indication information carried in the DCI is 3 slots.

[0175] The corresponding relationship between the 2-bit interval indication information carried in the DCI and the RS burst time interval is shown in Table 1:

[0176] 2-bit bit value value of time interval 00 2 01 3 10 4 11 5

[0177] Table 1

[0178] The corresponding relationship between the interval indication information of the temporary RS burst (RS burst) defined in Table 1 and the RS burst time interval is determined in a protocol predefined manner or configured through RRC signaling.

[0179] It should be noted that the corresponding relationship between the interval indication information of the RS burst and the value of the time interval in the embodiment is only an example, and the embodiment of the disclosure does not exclude any corresponding relationship combination. That is, the RRC signaling can configure any value set, and the protocol can also define any value set. In addition, any element of Table 1 can be used alone or in combination with one or more other elements.

[0180] It is assumed that the network side triggers two temporary RS bursts for AGC settling and T / F tracking, respectively. The base station indicates the time interval between the two temporary RS bursts triggered by the base station through interval indication information carried in a MAC CE. Exemplarily, the network side indicates the time interval between the temporary RS bursts through N-bit interval indication information carried in the MAC CE.

[0181] In this embodiment, it is assumed that N = 2.

[0182] The MAC CE is used to trigger a temporary RS. After the temporary RS is triggered, the temporary RS is transmitted between the base station and the terminal.

[0183] The correspondence between the 2-bit interval indication information carried in the MAC CE and the time interval of the temporary RS burst can be as shown in Table 2:

[0184] 2-bit bit value value of time interval 00 2 01 3 10 4 11 5

[0185] Table 2

[0186] The correspondence between the interval indication of the temporary RS burst defined in Table 2 and the time interval of the temporary RS burst is determined in a protocol predefined manner or configured through RRC signaling.

[0187] It should be noted that the correspondence table between the RS burst time interval indication and the time interval value in this embodiment is only an example, and the embodiments of the present disclosure do not exclude any correspondence combination. That is, the RRC signaling can configure any value set, and the protocol can also define any value set. In addition, any element of Table 2 can be used alone or in combination with one or more other elements.

[0188] It is assumed that the network side triggers two temporary RS bursts for AGC settling and T / F tracking, respectively. The base station indicates the time interval between the two temporary RS bursts triggered by the base station through interval indication information carried in a MAC CE.

[0189] Exemplarily, the network side implicitly indicates the time interval between the two temporary RS bursts of adjacent transmission through temporary RS triggering information carried in the MAC CE.

[0190] Exemplarily, when configuring temporary RS, the network side needs to configure the time interval between the temporary RS bursts for each set of temporary RS resources. The network side determines which temporary RS configuration in the RRC signaling configuration list the activated temporary RS is through temporary RS triggering information carried in the MAC CE. Then, according to the configuration number, the corresponding temporary RS configuration is determined, including the time interval information between the temporary RS bursts.

[0191] Reference Figure 11 As shown, the MAC CE can implicitly indicate or explicitly indicate the time interval of the two temporary RS bursts of adjacent transmission. Figure 11 The time interval indicated by the MAC CE is 3 slots.
