For the convenience of description, the above-mentioned devices are collectively referred to as terminal devices. The number of terminal devices 10 is usually multiple, and one or more terminal devices 10 can be distributed in a cell managed by each access network device 20. The terminal device can also be referred to as a terminal or a UE, and those skilled in the art can understand its meaning.

[0034] The access network device 20 is a device deployed in an access network to provide wireless communication functions for the terminal device 10. The access network device 20 can include various forms of macro base stations, micro base stations, relay stations, APs (Access Points), and the like. In systems using different wireless access technologies, the names of devices with access network device functions can be different, for example, in a 5G NR (New Radio) system, it is called gNodeB or gNB (Next Generation Node B). With the evolution of communication technology, the name of the "access network device" can change. For the convenience of description, in the embodiments of the present application, the above-mentioned devices that provide wireless communication functions for the terminal device 10 are collectively referred to as access network devices. In some embodiments, through the access network device 20, a communication relationship can be established between the terminal device 10 and the core network element 30. Illustratively, in the LTE (Long Term Evolution) system, the access network device 20 can be an EUTRAN (Evolved Universal Terrestrial Radio Access Network) or one or more eNodeBs in the EUTRAN; in the 5G NR system, the access network device 20 can be a RAN (Radio Access Network) or one or more gNBs in the RAN. In the embodiments of the present application, the "network device" refers to the access network device 20, such as a base station, unless otherwise specified.

[0035] The core network element 30 is a network element deployed in the core network, and the main functions of the core network element 30 are to provide user connection, management of users, and completion of bearer for services, and to provide an interface to external networks as a bearer network. For example, the core network element in the 5G NR system can include AMF (Access and Mobility Management Function) entities, UPF (User Plane Function) entities, and SMF (Session Management Function) entities, and the like.

[0036] In some embodiments, the access network device 20 and the core network element 30 communicate with each other through some air interface technology, such as the NG interface in the 5G NR system. The access network device 20 and the terminal device 10 communicate with each other through some air interface technology, such as the Uu interface.

[0037] The "5G NR system" in the embodiments of the present application can also be referred to as a 5G system or an NR system, but those skilled in the art can understand its meaning. The technical solutions described in the embodiments of the present application can be applicable to an LTE system, a 5G NR system, an evolved system (such as a B5G (Beyound 5G) system, a 6G system (6th Generation System, 6th generation mobile communication system)) after the 5G NR system, and other communication systems such as an NB-IoT (Narrow Band Internet of Things, Narrow Band Internet of Things) system, and the present application does not limit this.

[0038] In the embodiments of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through transmission resources (for example, frequency domain resources, or spectrum resources) on a carrier used by the cell. The cell can be a cell corresponding to the network device (for example, a base station), and the cell can belong to a macro base station or a base station corresponding to a small cell (Small cell). The small cell can include a metro cell, a micro cell, a pico cell, a femto cell, etc., and these small cells have the characteristics of small coverage and low transmit power, and are suitable for providing high-speed data transmission services.

[0039] Before introducing the technical solutions of the present application, some related technical knowledge involved in the present application will be introduced and explained. The following related technologies can be combined with the technical solutions of the embodiments of the present application in any way, and all belong to the protection scope of the embodiments of the present application. The embodiments of the present application include at least part of the following content.

[0040] Currently, with the pursuit of rate, delay, high-speed mobility, and energy efficiency, and the diversity and complexity of future life services, the 3GPP international standard organization has begun to develop 5G. The main application scenarios of 5G are: enhanced mobile broadband (Enhanced Mobile Broadband, eMBB), low latency and high reliability communication (Ultra Reliable Low Latency Communications, URLLC), and massive machine type communication (Massive Machine Type Communications, mMTC).

[0041] eMBB still targets users to obtain multimedia content, services and data, and its demand grows very rapidly. On the other hand, since eMBB can be deployed in different scenarios, such as indoor, urban, rural, etc., its capability and demand are quite different, so it cannot be generalized and must be analyzed in detail in combination with the specific deployment scenario. Typical applications of URLLC include industrial automation, power automation, remote medical operation (surgery), traffic safety assurance, etc. Typical features of mMTC include high connection density, small data volume, delay-insensitive service, low cost and long service life of modules, etc.

[0042] NR can also be deployed independently. In order to reduce air interface signaling and quickly recover wireless connection in 5G network environment, a new RRC state, RRC_INACTIVE state, is defined for the purpose of quickly recovering data service. This state is different from RRC_IDLE and RRC_ACTIVE states.

[0043] RRC_IDLE: mobility is based on UE's cell selection / reselection, paging is initiated by CN (Core Network), and paging area is configured by CN. There is no UE AS (Access Stratum) context on the base station side. There is no RRC connection.

[0044] RRC_CONNECTED: there is RRC connection, and there is UE AS context between the base station and the UE. The network side knows the location of the UE is specific to the cell level. Mobility is network-controlled mobility. Unicast data can be transmitted between the UE and the base station.

[0045] RRC_INACTIVE: mobility is based on UE's cell selection / reselection, there is a connection between CN and NR, UE AS context exists on a certain base station, paging is triggered by RAN (Radio Access Network), RAN-based paging area is managed by RAN, and the network side knows the location of the UE is based on the RAN-based paging area level.

[0046] 1. 5G network energy saving project

[0047] Energy consumption has become an important part of the operator's operating costs. In related technologies, the energy cost of a mobile network accounts for about 23% of the total cost of an operator. Most of the energy consumption comes from the radio access network, especially the active antenna unit (AAU), while the data center and fiber transmission only account for a small share. Power consumption includes two types:

[0048] - Dynamic part: such as consumption when data is transmitted / received.

[0049] - Static part: e.g. keeping necessary radio access equipment operational even if there is no ongoing data transmission / reception at this time.

[0050] The study shall not only evaluate the potential network energy consumption benefits, but also evaluate and balance the impact on network and user performance. For example the study shall not have a particularly large impact on some KPIs (Key Performance Indicators) such as: spectral efficiency, capacity, UPT (User Perceived Throughput), latency, UE power consumption, complexity, handover performance, call drop rate, initial access performance, etc.

[0051] Possible study directions are as follows:

[0052] 1. Specify procedures and signaling method(s) to support on-demand SSB SCell operation for UEs in connected mode configured with CA, for both intra- / inter-band CA.

[0053] • Specify triggering method(s) (select from UE uplink wake-up-signal using an existing signal / channel, cell on / off indication via backhaul, Scell activation / deactivation signaling)

[0054] • Note1: On-demand SSB transmission can be used by UE for at least SCell time / frequency synchronization, L1 / L3 measurements and SCell activation, and is supported for FR1 and FR2 in non-shared spectrum.

[0055] 2. SSB-less cell

[0056] In the related art, a scell can not transmit SSB, but the premise is that this cell and sPcell or other scell cell are co-located cells. As a SSB-less scell, the UE synchronizes with another cell and can communicate on the SSB-less cell. The network energy saving project has extended the intra-band (wideband) scenario to the inter-band (wideband) scenario, that is, the SSB-less cell can obtain SSB through other inter-band cells.

[0057] In the related art, the SSB-less cell can work as an independent non-collocated cell. Then, when the SSB-less cell is an independently working cell, how to trigger the SSB-less cell to transmit SSB is a problem to be solved by the present application.

[0058] In the related art, a cell can not transmit SSB, but the premise is:

[0059] 1) This cell is an SCell, that is, limited to RRC connected state UE, and not applicable to sPcell;

[0060] 2) This cell and sPcell or other SCell cell are co-located cells.

[0061] In this case, the UE can acquire SSB from the Cell-A for the communication on the SSB-less scell-B, i.e. the above-mentioned "UE is synchronized with another cell, and can communicate on the SSB-less cell". In this scheme, the SSB-less SCell does not need to transmit SSB at all.

[0062] However, the above method can only be applied to the RRC connected state, and how to extend this SSB-less network energy saving mode to the UE in the RRC idle state and the RRC inactive state needs further discussion and research.

[0063] Please refer to FIG. 2, which shows a flowchart of an information transmission method provided by an embodiment of the present application, which is executed by a terminal device. The method includes the following step 210.

[0064] Step 210, the terminal device receives first configuration information, the first configuration information is used to configure time-frequency resources of the terminal device receiving or transmitting a first signal, and the first signal is used to instruct the terminal device to perform a data operation.

[0065] Correspondingly, the network device transmits the first configuration information.

[0066] In some embodiments, the terminal device receives the first configuration information on a first carrier. Correspondingly, the network device transmits the first configuration information on the first carrier.

[0067] In some embodiments, the first configuration information can also be configured by the network device in advance for the terminal device and transmitted to the terminal device, so that the terminal device can also not receive the first configuration information on the first carrier, but receive the first configuration information on other carriers.

[0068] In some embodiments, the first carrier refers to a cell or a cell group in which the terminal device resides. In some embodiments, the first carrier can also be replaced by a first carrier set, a first network, a first cell, a first cell group, a first beam, a first beam group, etc. to be applied to different scenarios, and the specific name can be referred to the actual application scenario of the method.

[0069] In some embodiments, the first configuration information is transmitted in a broadcast manner.

[0070] In some embodiments, the first configuration information is used to configure at least one of the following:

[0071] Time-frequency resources of the first signal;

[0072] Association relationship between the time-frequency resources of the first signal and the identity information of the terminal device;

[0073] Association relationship between the time-frequency resources of the first signal and the terminal device group information in which the terminal device resides.

[0074] In some embodiments, the identity information of the terminal device can comprise at least one of: identification information of the terminal device, identity of the terminal device. In some embodiments, the identification information of the terminal device is used to uniquely identify the terminal device. Illustratively, the identification information of the terminal device is an ID (Identity Document) of the terminal device. For example, the identification information of the terminal device can be one or more of: IMSI (International Mobile Subscriber Identification Number), TMSI (Temporary Mobile Subscriber Identity), GUTI (Globally Unique Temporary UE Identity). In some embodiments, the identity of the terminal device can be a role assumed by the terminal device in the communication system. Illustratively, the terminal device is a relay terminal device, for example, the terminal device is a relay station. Illustratively, the terminal device is an A-IOT (Ambient-Internet of Things) device.

[0075] In some embodiments, the association between the time-frequency resource of the first signal and the identity information of the terminal device can be a conversion relationship between the identity information of the terminal device and the time-frequency resource of the first signal. Illustratively, the identity information of the terminal device is an ID of the terminal device, and the association between the time-frequency resource of the first signal and the identity information of the terminal device is how to calculate the time-frequency resource of the first signal based on the ID of the terminal device.

[0076] In some embodiments, the association between the time-frequency resource of the first signal and the identity information of the terminal device is pre-configured. Illustratively, the association in the form of (identity information of the terminal device, time-frequency resource of the first signal) is indicated in the first configuration information, or the association in the form of a table in which the identity information of the terminal device and the time-frequency resource of the first signal correspond to each other is indicated in the first configuration information. The terminal device can determine the time-frequency resource of the first signal based on its own identity information and the association indicated in the first configuration information. Illustratively, an index corresponding to the identity information of the terminal device and an association between different indexes and the time-frequency resource of the first signal are indicated in the first configuration information, and the terminal device determines the time-frequency resource of the first signal based on the index corresponding to its own identity information.

[0077] In some embodiments, the first configuration information is used to indicate an association relationship between the identity information of the terminal device and the first value. For example, the association relationship in the form of (identity information of the terminal device, first value) is indicated in the first configuration information, or the association relationship in the form of a table in which the identity information of the terminal device and the first value correspond to each other is indicated in the first configuration information. The terminal device can determine the corresponding first value based on the identity information of the terminal device, and then determine the index of the time-frequency resource of the first signal according to the first value. For example, the terminal device processes the first value based on a preset rule to obtain the index of the time-frequency resource of the first signal. For example, the terminal device can determine the corresponding first value based on the identity information of the terminal device, and perform a modulo operation on the first value to obtain the index of the time-frequency resource of the first signal.

[0078] In some embodiments, the terminal device group information can include at least one of the following: identification information of the terminal device group, identity of the terminal device group. In some embodiments, the identification information of the terminal device group is used to uniquely identify the terminal device group. For example, the identification information of the terminal device group is the ID of the terminal device group. In some embodiments, the identity of the terminal device group is used to distinguish between different terminal device groups. The division method of the terminal device group is not limited in the present application. For example, the terminal device can be divided according to the characteristics of the terminal device, and the terminal device belongs to a mobile terminal device group, and the terminal devices included in the mobile terminal device group are all mobile terminal devices.

[0079] In some embodiments, the first configuration information can directly indicate the time-frequency resource of the first signal. In some embodiments, the first configuration information can also indicate the offset value of the time-frequency resource of the first signal from the time-frequency resource of the first configuration information.

[0080] In some embodiments, the first configuration information can indicate the accurate time-frequency resource of the first signal, or can indicate the time domain range in which the time-frequency resource of the first signal is located. For example, the first configuration information is used to configure the terminal device to send or receive the first signal in the first time domain range. The length of the first time domain range is not limited in the present application, and can be pre-configured or pre-defined, or can be determined by the network device.

[0081] In some embodiments, the first configuration information can further include at least one of the following: identity information of the terminal device, identity information of the terminal device group to which the terminal device belongs.

[0082] In some embodiments, after receiving the first configuration information, the terminal device performs the following step 220.

[0083] In step 220, the terminal device receives the first signal on the first carrier, or the terminal device sends the first signal on the first carrier.

[0084] Correspondingly, the network device transmits the first signal on the first carrier, or the network device receives the first signal on the first carrier.

[0085] In some embodiments, if the network device needs to transmit downlink data information or downlink command information to the terminal device, the network device initiates paging to the terminal device, and step 220 is implemented as that the terminal device receives the first signal on the first carrier.

[0086] In some embodiments, if the terminal device needs to transmit uplink data information or uplink command information to the network device, the terminal device needs to actively transmit information to the network device to establish a communication connection with the network device, and step 220 is implemented as that the terminal device transmits the first signal on the first carrier.

[0087] In some embodiments, the terminal device is in an RRC idle state or an RRC inactive state.

[0088] In some embodiments, the first signal is a small-bandwidth and simple-format signal, which is beneficial for power saving of the terminal device. In some embodiments, the first signal is used for at least data operation of the terminal device, and activates the terminal device to perform operation in a larger bandwidth, which is more power-consuming but can process more data.

[0089] The technical scheme provided by the embodiments of the present application configures the terminal device with time-frequency resources for receiving or transmitting the first signal through the first configuration information, so that the terminal device can listen to or transmit the first signal on the corresponding time-frequency resources, without blind detection of the first signal by the terminal device, reducing power consumption of the terminal device, and avoiding conflict between transmission of the first signal and other signals, improving stability of the communication system. The terminal device performs data operation after receiving or transmitting the first signal, so that the terminal device enters a power saving state when there is no data operation, reducing power consumption of the terminal device.

[0090] Next, the technical scheme of the embodiments of the present application will be introduced with two examples of a mechanism triggered by MT (Mobile Terminate, transmission to terminal) service and a mechanism triggered by MO (Mobile Original, transmission from terminal device) service.

In this way, only the association between the first signal and the second signal needs to be configured in advance, and the association between the first signal and the paging message or the association between the first signal and the RACH message does not need to be configured in advance, which is more flexible and facilitates real-time scheduling of the network device. Similarly, this also causes the terminal device to need to receive one more second signal, resulting in an increase in the energy consumption of the terminal device.

[0131] In some embodiments, when the amount of information that can be carried by the first signal is large, the first signal can carry all the information required by the terminal device, and the network device can also not send the second signal.

[0132] In some embodiments, the first signal can directly indicate the time-frequency resource of the second signal, or can indicate the association between the time-frequency resource of the second signal and the time-frequency resource of the first signal. For example, the first signal can indicate the offset value between the time-frequency resource of the second signal and the time-frequency resource of the first signal.

[0133] In some embodiments, the first signal can indicate the association between the time-frequency resource of the second signal and the content of the first signal. In some embodiments, the content of the first signal includes at least one of the following: the format of the first signal, the encoding mode of the first signal, and the amount of information included in the first information. For example, the time-frequency resource of the second signal is related to the encoding mode of the first signal, for example, the first signal is encoded using different sequences, and the corresponding time-frequency resource of the second signal is different. For example, the first signal is encoded using a z sequence, and the offset value between the time-frequency resource of the second signal and the time-frequency resource of the first signal is Offset1, and if the first signal is encoded using an m sequence, the offset value between the time-frequency resource of the second signal and the time-frequency resource of the first signal is Offset2. The format of the first signal can be the arrangement mode of different information domains in the first signal. For example, the first signal includes information domains 0 and 1, if the arrangement mode of the information domains in the first signal is information domain 0, 1, the offset value between the time-frequency resource of the second signal and the time-frequency resource of the first signal is Offset1, and if the arrangement mode of the information domains in the first signal is information domain 1, 0, the offset value between the time-frequency resource of the second signal and the time-frequency resource of the first signal is Offset2.

[0134] In some embodiments, the time domain resource occupied by the first reference signal is before the time domain signal occupied by the second signal, and therefore, the time-frequency resource of the second signal can also have a correlation relationship with the time-frequency resource of the first reference signal and / or the content of the first reference signal. Or the time-frequency resource of the first signal is explicitly indicated in the first signal, and the time-frequency resource of the second signal can also have a correlation relationship with the time-frequency resource of the first reference signal.

[0135] In some embodiments, if the network device needs to send downlink data information or downlink command information to the terminal device, it needs to send a paging message to the terminal device to establish a communication connection with the terminal device. At this time, the first signal can be used to indicate the related information of the paging message. Illustratively, the first signal can be used to indicate the time-frequency resource of the paging message.

[0136] In some embodiments, the correlation relationship between the time-frequency resource of the paging message and the time-frequency resource of the first signal can be an offset value between the time-frequency resource of the paging message and the time-frequency resource of the first signal. In some embodiments, the first signal can also be used to indicate the correlation relationship between the time-frequency resource of the paging message and the time-frequency resource of the first reference signal, the correlation relationship between the time-frequency resource of the paging message and the time-frequency resource of the second signal, and the correlation relationship between the time-frequency resource of the paging message and the time-frequency resource of the first configuration information, which are not limited by the present application.

[0137] In some embodiments, the correlation relationship between the time-frequency resource of the paging message and the content of the first signal can refer to the introduction of the correlation relationship between the time-frequency resource of the second signal and the content of the first signal, which will not be repeated here. In some embodiments, the first signal can also be used to indicate the correlation relationship between the time-frequency resource of the paging message and the content of the first reference signal, the correlation relationship between the time-frequency resource of the paging message and the content of the second signal, and the correlation relationship between the time-frequency resource of the paging message and the content of the first configuration information, which are not limited by the present application.

[0138] In some embodiments, the first signal can also be used to indicate the related information of the RACH message. Illustratively, the first signal can be used to indicate the time-frequency resource of the RACH message.

[0139] In some embodiments, the correlation relationship between the time-frequency resource of the RACH message and the time-frequency resource of the first signal can be an offset value between the time-frequency resource of the RACH message and the time-frequency resource of the first signal. In some embodiments, the first signal can also be used to indicate the correlation relationship between the time-frequency resource of the RACH message and the time-frequency resource of the first reference signal, the correlation relationship between the time-frequency resource of the RACH message and the time-frequency resource of the second signal, and the correlation relationship between the time-frequency resource of the RACH message and the time-frequency resource of the first configuration information, which are not limited by the present application.

[0140] In some embodiments, the association between the time-frequency resource of the RACH message and the content of the first signal can refer to the association between the time-frequency resource of the second signal and the content of the first signal, which will not be repeated herein. In some embodiments, the first signal can also be used to indicate the association between the time-frequency resource of the RACH message and the content of the first reference signal, the association between the time-frequency resource of the RACH message and the content of the second signal, and the association between the time-frequency resource of the RACH message and the content of the first configuration information, which will not be limited herein.

[0141] In some embodiments, the first signal can also be used to indicate the format information of the RACH message. In some embodiments, the format information of the RACH message includes at least one of the following: the length of the RACH message, the spreading factor, and the number of time domain units occupied by the RACH message.

[0142] In some embodiments, the first signal can also be used to indicate the association between the format information of the RACH message and the time-frequency resource of the first signal, the association between the format information of the RACH message and the content of the first signal, the association between the format information of the RACH message and the time-frequency resource of the second signal, the association between the format information of the RACH message and the content of the second signal, the association between the format information of the RACH message and the time-frequency resource of the paging message, and the association between the format information of the RACH message and the content of the paging message.

[0143] In some embodiments, the paging message and the RACH message have a corresponding relationship. In some embodiments, the receiving direction of the paging message has a corresponding relationship with the sending direction of the RACH message. For example, the sending direction of the paging message 1 corresponds to the receiving direction of the RACH message 1, and the sending direction of the paging message 2 corresponds to the receiving direction of the RACH message 2. This is beneficial for the network device to send the paging message and receive the RACH message in different directions.

[0144] In some embodiments, the group of paging messages and RACH messages having a corresponding relationship have corresponding positions in the time domain. In some embodiments, the group of paging messages and RACH messages having a corresponding relationship are continuous in the time domain, or the interval in the time domain is determined. For example, as shown in FIG. 4, the paging message 1 and the RACH message 1 are continuous in the time domain. For example, the interval between the paging message and the corresponding RACH message in the time domain is T time domain units, and T is a positive integer. In some embodiments, T can be predefined or preconfigured, or can be determined by the network device. In some embodiments, the time domain unit can be implemented as one or more of time slots or subframes. This is beneficial for the network device to save power consumption.

[0145] In some embodiments, to assist in sending the paging message, the network device may further send a first reference signal to the terminal device. The terminal device may perform L1 measurement and / or L3 measurement on the first reference signal to accelerate downlink synchronization of the terminal device.

[0146] In some embodiments, a group of first reference signals and paging messages having a corresponding relationship have corresponding positions in the time domain. In some embodiments, the first reference signal has a corresponding relationship with the paging message. In some embodiments, a group of paging messages and reference signals having a corresponding relationship are continuous in the time domain, or the interval in the time domain is determined. For example, as shown in FIG5 , RS (Reference Signal) 1 and paging message 1 are continuous in the time domain. For example, the interval between the first reference signal and its corresponding paging message in the time domain is T time domain units, where T is a positive integer. In some embodiments, T may be predefined or preconfigured, or it may be determined by the network device itself. In some embodiments, the time domain unit may be implemented as one or more of a time slot or a subframe.

[0147] In some embodiments, relevant information about the first reference signal may be indicated in the first configuration information, the first signal, and / or the second signal. In some embodiments, the first signal may be used to indicate parameter information related to the first reference signal. For example, the first signal may be used to indicate the time-frequency resource of the first reference signal.

[0148] In some embodiments, the first signal may also be used to indicate an association between parameter information related to the first reference signal and the time-frequency resources of the first signal, or an association between parameter information related to the first reference signal and the content of the first signal.

[0149] It should be noted that the association relationship between the two objects mentioned in the embodiments of the present application can be predefined or preconfigured, or it can be determined by the network device itself, and this application does not limit this.

[0226] Step 610: The terminal device receives first configuration information on a first carrier.

[0227] Correspondingly, the network device sends the first configuration information on the first carrier.

[0228] Step 610 is the same as step 210 described above, and details are referable to the description of step 210 in the above embodiments, which will not be repeated here.

[0229] Step 620: The terminal device sends a first signal on the first carrier.

[0230] Correspondingly, the network device receives the first signal on the first carrier.

[0232] Correspondingly, the network device sends the second signal on the first carrier and / or the second carrier.

[0233] Step 630 is the same as step 330 described above, and details are referable to the description of step 330 in the above embodiments, which will not be repeated here.

[0234] In some embodiments, in order to determine that the network device can receive the first signal, the method further comprises at least one of the following steps 650-670.

[0235] Step 650: The terminal device starts a first timer.

[0236] In some embodiments, the terminal device starts the first timer after sending the first signal. In some embodiments, the starting time of the first timer and the time length of the first timer can be predefined or preconfigured, or can be determined by the terminal device itself, which will not be limited in the present application. In some embodiments, the starting time of the first timer can be the sending time of the first signal. In some embodiments, the starting time of the first timer can be the sending time of the first signal + a first offset value. In some embodiments, the first offset value can be predefined or preconfigured, or can be determined by the terminal device itself, which will not be limited in the present application.

[0239] Step 670, in the case that the first timer expires, the step 630 is re-performed.

[0240] In some embodiments, the network device can not send the second signal, therefore, if the first timer is running, a second signal is received, or in the case that the acknowledgement information for the RACH message is received, it can be determined that the network device has received the first signal, then the first timer can be stopped.

[0241] Step 640, the terminal device sends a RACH message on the first carrier and / or the second carrier, the RACH message is used to establish a communication connection between the terminal device and the network device where the second carrier is located (in FIG. 6, the RACH message is received on the second carrier as an example).

[0246] In some embodiments, the second reference signal has a corresponding relationship with the RACH message. In some embodiments, the transmission direction of the second reference signal and the reception direction of the RACH message are corresponding. In some embodiments, the group of second reference signals and the RACH message having the corresponding relationship are continuous in time domain or the interval in time domain is determined.
