[0041] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0042] Figure 1 is a schematic diagram of an application scenario of an embodiment of this application.

[0043] As shown in Figure 1, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 via an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0044] It should be understood that the embodiments of this application are only illustrated by way of example with communication system 100, but the embodiments of this application are not limited thereto. That is to say, the technical solutions of the embodiments of this application can be applied to various communication systems, such as: Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), Internet of Things (IoT) system, Narrow Band Internet of Things (NB-IoT) system, enhanced Machine-Type Communications (eMTC) system, 5G communication system (also known as New Radio (NR) communication system), or future communication systems, etc.

[0045] In the communication system 100 shown in Figure 1, network device 120 may be an access network device that communicates with terminal device 110. The access network device can provide communication coverage for a specific geographical area and can communicate with terminal device 110 (e.g., UE) located within that coverage area.

[0046] Network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, a Next Generation Radio Access Network (NG RAN) device, a base station (gNB) in an NR system, a radio controller in a Cloud Radio Access Network (CRAN), or a relay station, access point, vehicle-mounted device, wearable device, hub, switch, bridge, router, or network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0047] Terminal device 110 can be any terminal device, including but not limited to terminal devices that are connected to network device 120 or other terminal devices via wired or wireless connections.

[0048] For example, the terminal device 110 can refer to an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. The access terminal can be a cellular phone, cordless phone, Session Initiation Protocol (SIP) phone, IoT device, satellite handheld terminal, Wireless Local Loop (WLL) station, Personal Digital Assistant (PDA), handheld device with wireless communication capabilities, computing device or other processing device connected to a wireless modem, in-vehicle device, wearable device, terminal device in a 5G network, or terminal device in a future evolved network, etc.

[0049] Terminal device 110 can be used for device-to-device (D2D) communication.

[0050] The wireless communication system 100 may further include a core network device 130 that communicates with the base station. This core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). Optionally, the core network device 130 may also be an Evolved Packet Core (EPC) device for an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions of both SMF and PGW-C. During network evolution, the aforementioned core network device may also be called by other names, or new network entities may be formed by dividing the core network functions; this embodiment does not limit this.

[0051] The various functional units in the communication system 100 can also establish connections and communicate with each other through the next generation (NG) interface.

[0052] For example, terminal devices establish air interface connections with access network devices through the NR interface for transmitting user plane data and control plane signaling; terminal devices can establish control plane signaling connections with the AMF through NG interface 1 (N1); access network devices, such as next-generation radio access base stations (gNB), can establish user plane data connections with the UPF through NG interface 3 (N3); access network devices can establish control plane signaling connections with the AMF through NG interface 2 (N2); the UPF can establish control plane signaling connections with the SMF through NG interface 4 (N4); the UPF can interact with the data network for user plane data through NG interface 6 (N6); the AMF can establish control plane signaling connections with the SMF through NG interface 11 (N11); and the SMF can establish control plane signaling connections with the PCF through NG interface 7 (N7).

[0053] Figure 1 exemplarily illustrates a base station, a core network device, and two terminal devices. Optionally, the wireless communication system 100 may include multiple base station devices, and each base station may include other numbers of terminal devices within its coverage area. This application embodiment does not limit this.

[0054] It should be noted that Figure 1 is merely an example illustrating the system to which this application applies. Of course, the method shown in the embodiments of this application can also be applied to other systems. Furthermore, the terms "system" and "network" are often used interchangeably in this document. The term "and / or" in this document merely describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. It should also be understood that "instruction" mentioned in the embodiments of this application can be a direct instruction, an indirect instruction, or an indication of a related relationship. For example, A instructing B can mean that A directly instructs B, for example, B can be obtained through A; it can also mean that A indirectly instructs B, for example, A instructs C, B can be obtained through C; or it can mean that there is a related relationship between A and B. It should also be understood that "correspondence" mentioned in the embodiments of this application can indicate a direct or indirect correspondence between two things, or an related relationship between two things, or a relationship of instruction and being instructed, configuration and being configured, etc. It should also be understood that the "predefined" or "predefined rules" mentioned in the embodiments of this application can be implemented by pre-storing corresponding codes, tables, or other means that can be used to indicate relevant information in the device (e.g., including terminal devices and network devices), and this application does not limit the specific implementation method. For example, predefined can refer to those defined in a protocol. It should also be understood that in the embodiments of this application, the "protocol" can refer to standard protocols in the field of communication, such as the LTE protocol, the NR protocol, and related protocols applied to future communication systems, and this application does not limit this.

[0055] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0056] In an NR system, the initial access process generally includes the following steps:

[0057] First, during the system information measurement and acquisition phase, after powering on, the UE searches for the Synchronization Signal and PBCH Block (SSB) in the network (NW). For the UE, measuring and selecting the optimal SSB serves to obtain downlink time synchronization, determine the uplink transmission beam direction, and decode the Physical Broadcast Channel (PBCH) within the SSB. The PBCH contains the higher-layer Master Information Block (MIB), which in turn contains scheduling information for the Physical Downlink Shared Channel (PDSCH) carrying system information (SIB1).

[0058] In this system, user equipment (UE) can scan and measure the SSBs transmitted from the base station to evaluate signal quality (such as L1-RSRP) and select the optimal SSB for access. Figure 2 is a schematic diagram of the structure of a synchronization signal block provided in an embodiment of this application. As shown in Figure 2, the SSB includes a primary synchronization signal (PSS), a secondary synchronization signal (SSS), a physical layer broadcast channel (PBCH), and a PBCH demodulation reference signal (DMRS). The PSS and SSS contain 12 physical channel resource blocks (PRBs) in the frequency domain, while the PBCH contains 20 PRBs in the frequency domain. The SSB can indicate the cell identity document (ID), support UE time-frequency synchronization, obtain MIB information, assist in cell search, and be used for radio resource management (RRM) and radio link management (RLM) measurements, etc.

[0059] In NR (also known as 5G), because 5G system bandwidth is often 100MHz, far exceeding that of 4G (maximum 400MHz), a beam scanning mechanism is introduced to meet coverage requirements, essentially trading time for space. To this end, 5G periodically transmits SSBs in the time domain in the form of Synchronous Broadcast Block Sets (SS burst sets). Each SS burst set contains multiple SSBs, which are transmitted using different beam directions, thus achieving coverage in different directions. The transmission period of the SSBs can vary from 5 milliseconds to 160 milliseconds; for example, it can be {5, 10, 20, 40, 80, 160} ms, which can be configured via higher-layer signaling. However, for UEs performing initial cell search, they cannot receive higher-layer signaling regarding the transmission period of the SSB burst set before searching for SSBs. Therefore, a default period needs to be defined. In the NR system, the default period for UEs performing initial cell search is defined as 20ms. When the relevant higher-layer signaling received by the UE contains periodic information of the SSB burst set, the period of the SSB burst set can be determined through this information; otherwise, the UE defaults to a period of 5ms for the SSB burst set of the serving cell.

[0060] Figure 3 is a schematic diagram of beam scanning provided in an embodiment of this application. As shown in Figure 3, taking an SSB burst set transmission period of 20 milliseconds and each SSB burst set including 8 SSBs as an example, corresponding to SSB numbers (also called indices) #0 to #7 respectively, different SSBs are for different beam directions, and the transmission time of the SSB in each transmission period is limited to a half-frame of 5 milliseconds, thereby ensuring that UEs in different directions can receive SSBs with sufficiently high Reference Signal Receiving Power (RSRP). For User Equipment 1, its signal strength is the highest on beam #1, so it can be selected as the best SSB to establish a connection with the base station; for User Equipment 2, its signal strength is the highest on beam #7, so it can be selected as the best SSB to establish a connection with the base station.

[0061] Furthermore, after selecting the best SSB, the UE can decode the PBCH to obtain the MIB information. Based on the configuration information in the MIB and the system message transmission method determined in the protocol, the UE blindly detects the scheduling physical downlink control channel (PDCCH) of system messages from CORESET#0 and Search Space#0, decodes the PDSCH carrying SIB1 from the PDCCH, and thus obtains the RACH configuration information in SIB1. Here, CORESET is the set of PDCCH candidate sets on time and frequency resources, while Search Space is the search range of the PDCCH candidate sets within CORESET.

[0062] Next is the RACH stage. In NR Rel.15, a four-step RACH process was supported; in later versions, a two-step RACH process (divided into Step A and Step B) was also supported. Here, we will use the four-step RACH as an example for explanation.

[0063] (1) Transmission of random access preamble (Preamble as Msg.1). The UE selects a random access preamble and transmits it to the base station's transmission point (TRP) on the PRACH. The PRACH preamble sequence consists of a root sequence and its cyclic shift. The PRACH preamble defines the specific format of the PRACH preamble, including time-domain resources and frequency-domain resources.

[0064] (2) Random Access Response (RAR) (RAR as Msg.2). After receiving the preamble, the base station sends a RAR to the UE, which includes Timing Advance (TA), Uplink Resource Grant (UL grant), and Cell-Radio Network Temporary Identifier (C-RNTI). The UE listens to the PDCCH to receive the RAR. If the UE successfully receives a RAR and the preamble sequence in the RAR is the same as the preamble sequence sent by the UE, it is considered that the RAR has been successfully received, uplink resources have been obtained, and uplink data can be sent.

[0065] (3) RRC Connection Request (Msg.3). The UE sends an RRC Setup Request message using the uplink resources allocated in the RAR. This message contains the UE identifier and the reason for establishment. This step is part of the contention-based random access procedure.

[0066] (4) RRC Connection Device (Msg.4). After receiving the RRC connection request, the base station sends an RRC connection setup message to confirm the connection request and allocate the necessary resources. This message is used to resolve possible contention-based preamble sequence conflicts and marks the completion of the initial access procedure.

[0067] However, in 6G communication systems, to further reduce base station power consumption, the base station needs to determine whether there are UEs in RRC idle state within the cell, and even obtain information such as the number, location, and direction of these UEs, in order to determine whether to send synchronization signals and broadcast messages. In existing 5G communication systems, UEs in RRC idle state do not send any uplink signals other than PRACH, therefore the base station cannot obtain the above information.

[0068] Based on this, embodiments of this application provide a signal transmission method, an information reception method, and an apparatus, device, chip, and medium. An idle terminal device sends a first signal to a network device, enabling the network device to determine if an idle terminal device exists within the cell. In this way, the network device can determine whether an idle terminal device exists within the cell. If so, it further acquires information such as the location and number of these terminal devices, thereby optimizing the spatial filter for signal and broadcast channel transmission based on this information, thus saving power consumption and optimizing network quality for the terminal device.

[0069] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0070] In one embodiment of this application, Figure 4 is a schematic diagram of the interaction process between a terminal device and a network device provided in this application embodiment. As shown in Figure 4, the signal transmission method, information reception method and apparatus, device, chip and medium provided in this application embodiment may include:

[0071] S210, the terminal device sends a first signal to the network device. Correspondingly, the network device receives the first signal sent by the terminal device.

[0072] In this context, when the terminal device is in an idle state, the first signal is used by the network device to determine whether the terminal device is in an idle state.

[0073] In this application embodiment, for example, the terminal device may include a UE, and the network device may include a base station.

[0074] In this embodiment of the application, the terminal device being in an idle state can refer to the RRC connection between the terminal device and the network device being in an idle state.

[0075] In this embodiment, the first signal may also be called a heartbeat signal (HBS) or an indication signal, etc., and is not specifically limited thereto. The first signal can be used to indicate to the network device that the terminal device sending the signal is currently in an idle state.

[0076] It should be noted that the terminal device can send a first signal to the network device when it is in an idle state, based on the network device's instruction; if the terminal device is not in an idle state, it does not need to send a first signal to the network device. Accordingly, after receiving the first signal, the network device determines the information of the terminal devices in the cell that are in an idle state based on the received first signal and adjusts the downlink beam direction accordingly.

[0077] Based on this, the method provided in this application embodiment allows an idle terminal device to send a first signal to a network device, enabling the network device to identify the idle terminal device. In this way, the network device can determine whether an idle terminal device exists within the cell. If so, it further acquires information about these terminal devices and optimizes the spatial filter for signal and broadcast channel transmission based on this information, thereby saving network device power consumption and optimizing the network quality of the terminal device.

[0078] In some embodiments, the first signal is further used by the network device to determine the location information and / or orientation information of the terminal device.

[0079] In this embodiment, the network device can determine one or more of the terminal device's location information and direction information within the cell based on information such as the time of the first signal sent by the terminal device. The location information refers to the approximate location of the terminal device within the cell, and the direction information can refer to the direction of the terminal device relative to the network device. The specific information determined by the network device based on the first signal sent by the terminal device can be determined according to the network device's information accuracy and the configuration of the first signal. In some embodiments, the network device can also determine the number of terminal devices in an idle state based on the number of first signals received.

[0080] Furthermore, the network device can optimize the spatial filter used for transmitting synchronization signals and broadcast channels based on the location information and / or direction information of the terminal devices, i.e., adjust the direction of the downlink beam, or adjust the transmission period of the synchronization signals and broadcast channels. For example, if there are more idle terminal devices in a certain direction, the network device can reduce the downlink beam transmitted in that direction.

[0081] Based on this, the method provided in this application embodiment allows the network device to determine the location information and / or direction information of the terminal device according to the first signal. This enables the network device to obtain information such as the location and direction of idle terminal devices within the cell, and to adjust the downlink beam direction accordingly, thereby reducing the power consumption of the network device.

[0082] In some embodiments, the first signal is determined based on a first sequence.

[0083] It should be noted that the first sequence can be a sequence dedicated to the first signal. The first sequence can also be a multiplexed random access sequence, and this application embodiment does not impose any restrictions on this.

[0084] In this embodiment of the application, the first sequence is determined based on the actual configuration. It can be an existing sequence for uplink communication between the terminal device and the network device, or a custom sequence pre-written into the terminal device and the network device.

[0085] The terminal device generates a first signal based on the format requirements of the first sequence, and sends the first signal to the network device based on the instructions of the network device. The network device can obtain the content of the first signal according to the first sequence agreed upon by both parties.

[0086] In some embodiments, the first sequence is a random access sequence.

[0087] In this embodiment, the random access sequence can refer to the PRACH sequence format. Configuration parameters can be added to the PRACH sequence format to generate a first signal. For example, the configuration parameter can be 1 bit of data to indicate to the network device that the terminal device sending the first signal is in an idle state. In this way, the first signal shares the PRACH sequence format with other signals, reducing the amount of data exchange between the terminal device and the network device, while still enabling the transmission of the first signal.

[0088] In some embodiments, the cyclic prefix length of the first signal is greater than the first length; wherein the first length is the cyclic prefix length of the uplink signal sent by the terminal device when it is in a connected state.

[0089] In this embodiment, the maximum cyclic prefix length of the uplink signal sent by the terminal device to the network device when the terminal device is in a connected state is determined as the first length. Regardless of the sequence from which the first signal is generated, the cyclic length of the first signal can be set to be greater than the first length. This is done to increase the reception time of the first signal, thereby improving the time tolerance of the network device and preventing the network device from missing the first signal.

[0090] Based on this, the method provided in the embodiments of this application generates a first signal based on a first sequence, such as a random access sequence, and the length of the generated first signal is greater than a first length. This reduces the amount of communication data between the network device and the terminal device, improves communication efficiency, enhances time tolerance, and thus improves the reliability of the network device.

[0091] In another embodiment of this application, in step S210, the terminal device sending the first signal can be: the terminal device sends the first signal on the first resource, and correspondingly, the network device receiving the first signal can be: the network device receives the first signal on the first resource.

[0092] The first resource is at least a portion of one or more second resources.

[0093] It should be noted that the second resource can be understood as the resource that network devices use to listen to the first signal.

[0094] It should also be noted that the number of second resources includes one or more, and the terminal device can select some resources (referred to as the first resource in this embodiment) from one or more second resources to send the first signal.

[0095] In some embodiments, the second resource may be a resource dedicated to transmitting the first signal; for example, the second resource may be referred to as an HBS resource.

[0096] In some embodiments, the second resource can reuse an existing PRACH resource; that is, the second resource can be a PRACH resource.

[0097] The second resource may include time-domain, frequency-domain, or other resources, which are allocated by the network device to the terminal device. After the terminal device determines at least one allocated second resource, it may select one or more of the second resources as the first resource according to the rules defined in the following embodiments, and send a first signal to the network device on the first resource. For the network device, different second resources may be allocated to terminal devices located at different positions and / or directions within the cell.

[0098] It should be noted that the network device can receive the first signal sent by the terminal device on the first resource corresponding to the terminal device, and thereby determine the location information and / or direction information of the terminal device based on the first signal.

[0099] Thus, in this embodiment of the application, the first resource includes one or more second resources, and the first signal is transmitted on the first resource, which enables different terminal devices to transmit signals based on different first resources, thereby facilitating the network device to determine the information of the terminal device.

[0100] It should be noted that network devices can directly or indirectly indicate one or more second resources. The following descriptions will focus on Method 1 (direct indication) and Method 2 (indirect indication).

[0101] Method 1: The network device directly designates one or more secondary resources.

[0102] In yet another embodiment of this application, the method may further include:

[0103] S203, the network device sends the first information to the terminal device. Correspondingly, the terminal device receives the first information.

[0104] The first information is used to configure one or more second resources.

[0105] In this embodiment, the first message may refer to a message sent by a network device to a terminal device for configuring one or more second resources on the terminal device. Figure 5 is a schematic diagram of a second resource provided in this embodiment. As shown in Figure 5, the explanation will focus on the example of the first message indicating four second resources to the terminal device. The network device sends the first message to the terminal device, and the terminal device parses the first message to obtain the locations of the four second resources.

[0106] It should be noted that if the first information indicates that the terminal device is configured with multiple second resources, the multiple second resources can be continuous in time to avoid resource fragmentation caused by the second resources; or, the multiple second resources can be spaced out in time, so as to provide the network device with time to switch the spatial receiving filter.

[0107] In some embodiments, the first information includes one or more of the following:

[0108] The first cycle of one or more secondary resources;

[0109] The temporal location of one or more second resources;

[0110] Frequency domain location of one or more second resources.

[0111] In this embodiment of the application, at least one second resource can be directly written into the first information by the network device, which includes at least one of the first period, time domain location, or frequency domain location, to configure the terminal device.

[0112] The first period of one or more second resources may refer to the time difference in the time domain between one of the at least two second resources indicated by the current first information and the corresponding second resource in the next at least two second resources indicated by the first information. The value of the first period may be determined by a preset and written into the first information to indicate to the terminal device, or it may be calculated and determined by the terminal device based on the time domain position of the indicated one or more second resources.

[0113] The first information can directly indicate the time-domain location of the first second resource. Referring to Figure 5, for example, it can be the time-domain location of second resource 1, and other second resources can be determined by the pre-configured time interval between the second resources. Alternatively, the first information can indicate the time-domain location of each or more of the second resources. The first information can also directly indicate the frequency-domain location of one or more second resources. This information can be directly written into the first information or determined by the terminal device based on the frequency-domain location of the first information.

[0114] It should be noted that the first information should include at least the time domain location of one or more second resources, while the remaining information can be calculated or directly determined by the terminal device based on pre-configured parameters.

[0115] It should be noted that there are several ways for a network device to directly configure one or more secondary resources. In one possible implementation, the network device can configure one or more secondary resources statically or semi-statically. In another possible implementation, the network device can configure one or more secondary resources dynamically. In yet another possible implementation, the network device can configure one or more secondary resources using a combination of dynamic and static methods.

[0116] Method 1a: Dynamic Configuration

[0117] In some embodiments, Figure 6 is a schematic diagram of the interaction process between a terminal device and a network device provided in the present application. As shown in Figure 6, the first information is carried by the first DCI.

[0118] In this embodiment of the application, the first information may be carried by dynamic signaling, such as the first downlink control information (DCI) carried by PDCCH, which directly indicates one or more second resources to the terminal device.

[0119] In another embodiment of this application, Figure 7 is a schematic diagram of the interaction process between a terminal device and a network device provided in an embodiment of this application. As shown in Figure 7, the method may further include:

[0120] S205, the network device transmits a first DCI and / or a second DCI on the third resource. Accordingly, the terminal device detects the first DCI and / or the second DCI on the third resource.

[0121] The third resource includes one or more of the following:

[0122] The timing of paging by the terminal device;

[0123] The activation period of discontinuous reception DRX cycles;

[0124] The first control resource set is used to schedule broadcast messages.

[0125] In this embodiment of the application, in order to avoid increasing the power consumption of the terminal device detecting the PDCCH in the RRC idle state, the first DCI and the second DCI are only sent to the terminal device within a specific transmission opportunity, namely on the third resource.

[0126] It should be noted that third-party resources may include at least one of the following:

[0127] (1) In addition to detecting the paging message within the paging opportunity, the terminal device can also detect the first DCI and / or the second DCI.

[0128] (2) Activation period during the Discontinuous Reception (DRX) cycle. Figure 8 is a schematic diagram of a third resource provided in an embodiment of this application. As shown in Figure 8, the terminal device can configure the DRX cycle, activation time, inactivity time, third resource, etc., through broadcast messages.

[0129] (3) Within the control resource set (CORESET) for scheduling broadcast messages, the broadcast message may, for example, be SIB1 or other broadcast messages.

[0130] In some embodiments, the first PDCCH carrying the first DCI is scrambled using the first RNTI, wherein...

[0131] The first RNTI is different from the second PDCCH. The second PDCCH is the PDCCH for scheduling paging messages of terminal devices, and / or the PDCCH for scheduling broadcast messages.

[0132] It should be noted that when a terminal device is listening to the PDCCH channel, it will attempt to descramble and decode the received PDCCH using the RNTI it knows. If the terminal device can successfully decode a PDCCH and its Cyclic Redundancy Check (CRC) matches the expected RNTI, then it can determine that the PDCCH was sent to it and can take appropriate action based on the DCI information contained therein.

[0133] Furthermore, to distinguish whether the PDCCH carries the first DCI or other DCIs, different scrambling methods can be used for PDCCHs carrying different DCIs. This scrambling is known to both the network device and the terminal device. For example, the first PDCCH carrying the first DCI uses the first RNTI scrambling, and the second PDCCH carrying other DCIs uses the second RNTI scrambling.

[0134] Other DCIs may include the aforementioned scheduling paging DCI, scheduling broadcast message DCI, etc. For example, if a terminal device discovers during decoding that the PDCCH is scrambled using P-RNTI, it can determine that this PDCCH is a scheduling paging DCI. If the terminal device discovers that the PDCCH is scrambled using the scheduling system message RNTI, it determines that this PDCCH is a broadcast message. If the terminal device discovers that the PDCCH is scrambled using another RNTI, it can consider that this PDCCH carries the first DCI. It should be noted that the PDCCH carrying the second DCI can also refer to this embodiment, using a different RNTI scrambling than the PDCCH carrying other DCIs, and this scrambling is jointly known by the network device and the terminal device.

[0135] Thus, in this embodiment, the network device sends a first DCI and / or a second DCI to the terminal device on the third resource, and the PDCCH carrying different DCIs uses different scrambling. This not only saves the power consumption of the terminal device detecting the PDCCH in the RRC idle state, but also simplifies the control mechanism and improves the utilization efficiency of uplink resources.

[0136] It should be noted that the first DCI can also be used to carry other information sent to the terminal device. Therefore, it can be pre-configured in both the network device and the terminal device so that after receiving the first DCI, the terminal device can determine whether it carries first information or other information through detection. If it determines that it carries first information, it can take action based on the first information and send a first signal to the network device on the first resource. Thus, in this embodiment, by carrying first information through the first DCI, the network device can flexibly control the configuration of the second resource, improving the utilization efficiency of uplink resources.

[0137] Method 1b: Semi-static signaling configuration

[0138] In some embodiments, Figure 9 is a schematic diagram of the interaction process between a terminal device and a network device provided in the present application. As shown in Figure 9, the first information is carried by a broadcast message.

[0139] In this embodiment, the network device can carry the first message via MIB, SIB1, or other broadcast messages or other RRC layer messages to configure one or more second resources. Preferably, carrying the first information via SIB1 helps reduce the number of broadcast messages that the terminal device needs to receive.

[0140] Thus, in this embodiment of the application, by carrying the first information through a broadcast message, the flexibility of configuring the second resource can be guaranteed.

[0141] Method 1c: Configuration using a combination of static and dynamic methods

[0142] Based on method 1b, in another embodiment of this application, Figure 10 is a schematic diagram of the interaction process between a terminal device and a network device provided in an embodiment of this application. As shown in Figure 10, the method may further include:

[0143] S204, the network device sends second information to the terminal device. Correspondingly, the terminal device receives the second information. The second information indicates a target second resource among one or more second resources; the first resource is at least a portion of the target second resources.

[0144] Based on the foregoing embodiments, the network device sends first information to the terminal device, configuring at least some information of one or more second resources for the terminal device. Building upon this, in the embodiments of this application, the network device can, through the second information—exemplarily static or semi-static signaling, such as MIB or SIB—configure other information of one or more second resources for the terminal device, and use this as the target second resource. The target second resource may refer to one or more second resources in the second information sent by the network device that indicate the terminal device is activating.

[0145] In this embodiment of the application, for example, a network device can configure information of the first period of one or more second resources for a terminal device through the first information, and then send the second information to the terminal device when it needs to obtain the first signal of the terminal device, and configure other information of one or more second resources for the terminal device through the second information, such as time domain location, frequency domain location, etc., so as to activate at least one second resource as a target second resource.

[0146] Furthermore, based on the scheme in the following embodiments, the terminal device selects at least a portion of the resources from at least one target second resource as the first resource, and sends a first signal to the network device based on the first resource.

[0147] In some embodiments, the target second resource includes M second resources whose time domain location is located after the first time domain location, where M is an integer greater than or equal to 1.

[0148] In this embodiment, the network device configures one or more second resources for terminal devices within the cell using first information, such as SIB1. Further, the second information sent by the network device can also be in the form of dynamic signaling. In this case, if the terminal device receives the second information, it confirms that the M second resources following the first time-domain location are the target second resources.

[0149] M is a standard preset value that is known to both network devices and terminal devices. Terminal devices can also use it to decode PDCCH.

[0150] In some embodiments, the first time-domain position is determined based on a first time offset parameter and the time-domain position of the terminal device receiving the second information.

[0151] It should be noted that the first time-domain position is not the time when the terminal device receives the second information, but rather the time-domain position at which the terminal device completes decoding the second information after receiving it. Specifically, the moment the terminal device receives the second information is considered the time-domain position of the terminal device receiving the second information, and the first time offset parameter is the duration of the terminal device decoding the second information. The first time-domain position is obtained by adding the first time offset parameter to the time-domain position of the terminal device receiving the second information.

[0152] In some embodiments, M is determined based on one or more of the following:

[0153] Predefined information;

[0154] Broadcast message;

[0155] Second information;

[0156] The number of synchronization signal blocks contained in the synchronization signal block burst set.

[0157] In this embodiment, M can be directly indicated to the terminal device by a broadcast message, a second message, or other predefined messages. For example, the value of M can be directly indicated in SIB1 or DCI, or written into a second message or broadcast message and sent to the terminal device. Alternatively, the value of M can also be indirectly indicated by the network device; for example, it can be equal to the number of SSBs in an SSB burst set indicated in SIB1, or a function of that number. It should be noted that the value of M can also be determined in other ways, which are not specifically limited here.

[0158] In some embodiments, the second information is carried via a second DCI.

[0159] In this embodiment of the application, the second information can be configured through dynamic signaling, such as the second DCI carried by the PDCCH, and sent to the terminal device at specific opportunities.

[0160] Thus, in this embodiment of the application, one or more second resources are configured for the terminal device using the first information, and then the second information is used to determine one or more second resources whose time domain position is located after the first time domain position as the target second resource for the terminal device. This not only simplifies the design of physical layer signaling, but also ensures a certain degree of flexibility.

[0161] Method 2: Indirect Configuration

[0162] In another embodiment of this application, one or more second resources are determined based on one or more fourth resources received by the terminal device from the reference signal.

[0163] In the embodiments of this application, the reference signal can be any one of SSB, MIB, SIB1, Channel State Information-Reference Signal (CSI-RS), or other reference signals.

[0164] In this embodiment, the network device can configure one or more second resources indirectly for the terminal device without configuring them through dedicated parameters. Specifically, the network device can send one or more reference signals to the terminal device via one or more fourth resources. It should be noted that after receiving the reference signals, the terminal device can determine the time-domain position of one or more second resources based on the time-domain position of the fourth resource that sent the reference signals, according to standard predefined rules and the reference signals.

[0165] It should be noted that a correspondence can be established between one or more second resources and one or more fourth resources. All second resources can be determined based on one of the fourth resources, or some second resources can be determined based on each fourth resource.

[0166] In some embodiments, the temporal location of any of the one or more second resources is spaced apart from the temporal location of the associated fourth resource by a second time offset parameter.

[0167] In this embodiment, the temporal location of the fourth resource can also be referred to as the time unit index of the fourth resource. Based on this, a second time offset parameter is added, which is the temporal location of the second resource associated with it, as determined by the terminal device, and can also be referred to as the time unit index of the second resource. The second time offset parameter can be a predefined time interval.

[0168] It should be noted that the association between the second and fourth resources can be jointly configured by the terminal device and the network device, or determined based on the fourth resource received by the terminal device. Different fourth resources can be associated with the beam direction, and the signal strength of the reference signal received based on different fourth resources will vary depending on the location of the terminal device. Therefore, the terminal device can select the fourth resource with the strongest RSRP and determine the time-domain location of one or more second resources associated with that fourth resource based on the selected fourth resource, and then send a first signal to the network device on the first resource determined based on the one or more associated second resources. In this way, the network device can determine the beam direction and / or the location of the terminal device.

[0169] It should also be noted that, depending on the level of detail required by the network device to know the location of the terminal device, one fourth resource can be configured to be associated with one second resource; or one fourth resource can be configured to be associated with multiple second resources, or multiple fourth resources can be configured to be associated with one second resource. No specific limitations are made here.

[0170] In some embodiments, the frequency domain location of the second resource is the same as the frequency domain location of its associated fourth resource;

[0171] The frequency domain position of the second resource is separated from the frequency domain position of the associated fourth resource by a first frequency domain offset parameter.

[0172] The frequency domain position of the second resource is the same as the first frequency domain position.

[0173] In this embodiment, the terminal device can determine the frequency domain position of one or more second resources based on the frequency domain position of the fourth resource and predefined rules. For example, after selecting the fourth resource, the terminal device can determine that the frequency domain position of the associated second resource is the same as the frequency domain position of the fourth resource, or is separated from the frequency domain position of the second resource by a first frequency domain offset parameter.

[0174] The first frequency domain offset parameter can be predefined in the network device and the terminal device or determined by the network device configuration.

[0175] It should be noted that, based on the aforementioned relationship between the fourth resource and the second resource, the time domain and frequency domain information of different fourth resources may differ within a period, and consequently, the time domain and frequency domain information of the second resource associated with them may also differ.

[0176] In some embodiments, any one of the second time offset parameter, the first frequency domain offset parameter, and the first frequency domain position is determined based on one or more of the following:

[0177] Predefined information;

[0178] Broadcast message.

[0179] In this embodiment, the network device can configure the aforementioned second time offset parameter, first frequency domain offset parameter, first frequency domain position, etc., through predefined information, such as MIB, or through broadcast messages, such as SIB1. It should be noted that the network device can also configure the above information through other information, which is not specifically limited here.

[0180] Thus, in this embodiment of the application, the network device sends a reference signal to the terminal device on one or more fourth resources, so that the terminal device can determine the time domain location, frequency domain location and other information of one or more second resources, thereby improving the configuration flexibility of the terminal device.

[0181] It should be noted that there is a correspondence between the second resource and the SSB resource. The relationship between the two is explained in detail below.

[0182] In another embodiment of this application, one or more second resources are associated with one or more fifth resources, and the one or more fifth resources are used to transmit SSB.

[0183] In this embodiment of the application, the fifth resource is used to transmit an SSB, wherein the SSB may be a first type of SSB, or the SSB may be a second type of SSB.

[0184] Figure 11 is a schematic diagram of an SSB provided in an embodiment of this application. As shown in Figure 11, the network device can send an SSB on the fifth resource in the following two ways:

[0185] In the first SSB transmission method, the network device sends SB burst sets according to a fixed period. The SSBs sent in each period have the same structure. Each SSB burst set contains one or more SSBs. Each SSB corresponds to an index. Different SSBs correspond to different downlink spatial filters, i.e. downlink beams.

[0186] The second SSB transmission method involves the network device transmitting a first type of SSB burst set according to a first cycle and a second type of SSB burst set according to a second cycle, where the first cycle is less than or equal to the second cycle. The structures of the first and second SSBs differ. Both the first and second SSB burst sets contain one or more first / second SSBs, and different SSBs correspond to different downlink spatial filters, i.e., downlink beams. The first SSB may only contain PSS information, while the second SSB may include both SSS and MIB information. It should be noted that different fifth resources can correspond to different downlink beams, and terminal devices at different locations may receive different signal strengths for different fifth resources. One or more fifth resources are associated with one or more second resources; that is, one or more associated second resources are configured to the terminal device through one or more fifth resources.

[0187] In this embodiment of the application, the terminal device selects the fifth resource with the best signal strength, and determines one or more second resources as the first resource based on the fifth resource, and sends a first signal to the network device on the first resource, so that the network device can determine the terminal device's position, orientation and other information based on the first signal.

[0188] In some embodiments, the first period of one or more second resources is the same as the second period of one or more fifth resources, and the one or more second resources in each first period are associated with one or more fifth resources in the same second period.

[0189] In this embodiment of the application, Figure 12 is a schematic diagram of a second resource provided in this embodiment. As shown in Figure 12, the example is given where the number of SSB resources (the fifth resource) and the second resource are both four, and the first period and the second period are the same. In this case, a second resource in a first period is associated with an SSB resource in a period. One SSB resource can be associated with one second resource. For example, SSB1 is associated with second resource 1, SSB2 is associated with second resource 2, SSB3 is associated with second resource 3, and SSB4 is associated with second resource 4. The association method between the SSB in the next second period and the second resource in the next first period can continue to refer to the current period.

[0190] It should be noted that since different SSB resources have different directions, the time-domain position, frequency-domain position, and other information of one or more second resources determined by the terminal device based on different SSB resources will also be different. Consequently, the terminal device sends a first signal to the network device based on the different first resources. The network device determines which SSB resource the second resource of the terminal device is associated with based on the first resource and the first signal. Then, it determines the location information and / or direction information of the terminal device based on the downlink beam direction of the SSB resource.

[0191] It should be noted that, when the first and second periods are the same, there is an association between a second resource with a given index and a fifth resource with the same index. Furthermore, a fifth resource can be associated with multiple second resources, or multiple fifth resources can be associated with a single second resource. It should also be noted that a fifth resource can be configured with one or more associated second resources on the terminal device based on the aforementioned configuration method. When multiple second resources are configured, the first second resource can be specified, and the other second resources are determined according to pre-configured parameters.

[0192] In some embodiments, when the number of second resources in each first period is the same as the number of fifth resources in each second period, one or more second resources in each first period correspond one-to-one with one or more fifth resources in the same second period; when the number of second resources in each first period is less than the number of fifth resources in each second period, each fifth resource in each first period is associated with multiple second resources in the same second period.

[0193] In this embodiment of the application, the quantity of the fifth resource in the first period may be the same as or different from the quantity of the second resource, depending on the association between the fifth resource and the second resource.

[0194] Referring to Figure 12, the number of second resources in the first period and the number of SSB resources (fifth resources) in the second period are both 4. Therefore, the 4 second resources in the same first period and the 4 fifth resources in the same second period are associated with each other.

[0195] Figure 13 is a schematic diagram of a second resource provided in an embodiment of this application. As shown in Figure 13, the example given is that the first period includes 2 second resources, the second period includes 4 second resources, and the first period and the second period are the same. In this case, the SSB resources with indices 1 and 2, namely SSB1 and SSB2, are associated with second resource 1, and the SSB resources with indices 3 and 4, namely SSB3 and SSB4, are associated with second resource 2. That is, two SSB resources correspond to one second resource.

[0196] It should be noted that, assuming the first and second periods are the same, as shown in Figure 13, if multiple fifth resources are associated with the same second resource, the number of fifth resources in the second period will be greater than the number of second resources in the first period. Alternatively, if one fifth resource is associated with multiple second resources, the number of fifth resources in the second period will be less than the number of second resources in the first period.

[0197] It should also be noted that network devices can configure one or more second resources to terminal devices through the fifth resource based on the aforementioned configuration method. The information configured in SSB1 and SSB2 shown in Figure 13 may be different based on different configuration methods, but they all point to the time domain location of the second resource 1.

[0198] In some embodiments, the first period of one or more second resources is M times the second period of one or more fifth resources; M is an integer greater than 1; one or more second resources in each first period are associated with multiple fifth resources in M ​​second periods.

[0199] In this embodiment of the application, the first period can be M times the second period, where M can be determined based on pre-configured rules and written into the network device and the terminal device.

[0200] Figure 14 is a schematic diagram of a second resource provided in an embodiment of this application. As shown in Figure 14, the example given is that a first period includes four second resources, a second period includes four SSB resources (fifth resources), and the first period is twice the length of the second period. In this case, a second resource in a first period is associated with an SSB resource in two second periods.

[0201] In some embodiments, when the number of second resources in each first period is the same as the number of fifth resources in each second period, the second resource with an index value of the first value in each first period is associated with the fifth resource with an index value of the first value in each of the M second periods; when the number of second resources in each first period is less than the number of fifth resources in each second period, any second resource in each first period is associated with multiple fifth resources in each of the M second periods.

[0202] In this embodiment, a second resource with a given index and SSB resources with the same index within M periods are associated. Referring to Figure 14, SSB resources in two second periods are associated with a second resource in a first period. When the number of SSB resources in each second period is equal to the number of second resources in the first period, an SSB resource with a given index is associated one-to-one with a second resource having the same index. For example, SSB1 in the first second period and SSB1 in the second period are both associated with second resource 1, ..., and SSB4 in the first second period and SSB4 in the second period are both associated with second resource 4.

[0203] Figure 15 is a schematic diagram of a second resource provided in an embodiment of this application. Referring to Figure 15, the example given is that the first period includes two second resources, the second period includes four SSB resources, and the first period is twice the length of the second period. Each SSB resource in both second periods is associated with a second resource in the first period, and a second resource with a given index is associated with multiple different SSB resources. For example, SSB1 and SSB2 in the first second period and SSB1 and SSB2 in the second period are all associated with second resource 1, and SSB3 and SSB4 in the first second period and SSB3 and SSB4 in the second period are all associated with second resource 2.

[0204] It should also be noted that if the network device, based on the aforementioned configuration method, directly indicates one or more associated second resources in the SSB resources, and uses the first SSB transmission method, based on the aforementioned embodiments, it can be determined that the first period can be equal to the second period, or an integer multiple of the second period. Within each period, if the number of second resources is the same as the number of SSB resources in the SSB burst set, there is an association between an HBS resource with a given index and an SSB resource with the same index, as shown in Figure 12 (the first period is the same as the second period) and Figure 14 (the first period is twice the second period).

[0205] It should also be noted that if the network device directly indicates one or more associated second resources in the SSB resources based on the aforementioned configuration method, and it is the first SSB transmission method, and the number of second resources is less than the number of SSB resources in the SSB burst set in each period, there is an association between a second resource with a given index and multiple SSB resources with different indices, as shown in Figure 13 (the first period is the same as the second period) and Figure 15 (the first period is twice the second period).

[0206] It should also be noted that if a network device, based on the aforementioned configuration method, directly indicates one or more associated second resources in the SSB resources, and uses the second SSB transmission method, since the terminal device can only obtain the configuration information of the second resource after decoding the second SSB, the period of the second resource can be equal to or an integer multiple of the second period. Similarly, within each period, the number of second resources should be the same as or less than the number of SSB resources in the SSB burst set.

[0207] It should also be noted that if the network device, based on the aforementioned embodiments, indicates one or more second resources to the terminal device via a reference signal, and the network device employs the first SSB transmission method, the first period can be equal to the second period. In this case, within each period, the number of second resources is equal to the number of SSB resources in the SSB burst set, and a second resource with a given index is associated with an SSB resource of the same index. Alternatively, within each period, the number of second resources is less than the number of SSB resources in the SSB burst set, and a second resource with a given index is associated with multiple SSB resources with different indices.

[0208] It should also be noted that if the network device, based on the aforementioned embodiments, indicates one or more second resources to the terminal device via a reference signal, and the network device employs a second SSB transmission method, the first period can be equal to the second period. In this case, within each period, the number of second resources is equal to the number of second SSB resources in the second SSB burst set, and a second resource with a given index is associated with second SSB resources of the same index. Alternatively, within each period, the number of second resources is less than the number of second resources in the second SSB burst set, and a second resource with a given index is associated with multiple second SSB resources with different indices.

[0209] Figure 16 is a schematic diagram of a second resource provided in an embodiment of this application. As shown in Figure 16, the example given is that the first period includes four second resources, the second period includes four second SSB resources, and the first period and the second period are the same. In this case, a second SSB resource with a given index is associated with a second resource with the same index. For example, second SSB1 is associated with second resource 1.

[0210] In some embodiments, the number of first resources includes one or more; the first resources include at least one or more second resources associated with the first SSB; the first SSB is an SSB whose measurement result satisfies the second condition.

[0211] In the embodiments of this application, the measurement results may include one or more of RSRP, RSRQ, and SINR, and there is no limitation here.

[0212] In this embodiment of the application, the second condition may include one or more of the following: the measurement result is optimal, the measurement result is greater than the first threshold, and no specific limitation is made here.

[0213] In this embodiment of the application, the terminal device determines a first SSB whose measurement result satisfies a second condition, and determines one or more second resources based on the first SSB, uses them as first resources, and sends a first signal to the network device on the first resource, so that the network device determines the location information and / or direction information of the terminal device.

[0214] In another embodiment of this application, the terminal device sends a first signal when a first condition is met.

[0215] In this embodiment of the application, after acquiring one or more second resources, the terminal device sends a first signal to the network device once when a first condition is met, or periodically sends a first signal to the network device.

[0216] In some embodiments, the terminal device receives first information; the first information is used to configure one or more second resources.

[0217] The terminal device receives second information; the second information is used to indicate a target second resource among one or more second resources;

[0218] The terminal device receives the third information; the third information is used to trigger the terminal device to send the first signal.

[0219] As mentioned above, the terminal device receives the first information sent by the network device and determines one or more second resources based on the first information.

[0220] Furthermore, the network device can also send second information to the terminal device, enabling the terminal device to identify a target second resource among one or more second resources. In this case, the terminal device can directly send a first signal to the network device, or it can temporarily refrain from sending the first signal and wait for a trigger condition to be met, i.e., receiving third information from the network device, before sending the first signal to the terminal device. For example, the third information can be a DCI indication issued by the network device. In this way, the network device can determine which SSB direction has a terminal device in an RRC idle state.

[0221] It should be noted that among the one or more second resources included in the first resource, at least the second resource associated with the SSB with the strongest RSRP is included.

[0222] In some embodiments, the first condition is determined based on one or more of the following:

[0223] Predefined information;

[0224] Broadcast message.

[0225] It should be noted that the aforementioned first condition can be determined based on broadcast messages or other predefined messages, such as a DCI indication carried by the PDCCH. If the terminal device receives a broadcast message or a predefined message from the network device, it confirms that the first condition has been met.

[0226] It should also be noted that when the terminal device receives a first message sent with predefined information and / or a broadcast message, or a first message and a second message, or a first message, a second message and a third message, it confirms that the first condition has been met.

[0227] Thus, in this embodiment of the application, when the terminal device meets the first condition, it sends a first signal to the network device. The first condition can be determined based on predefined information or a broadcast message, thereby improving the flexibility of control.

[0228] In another embodiment of this application, the network device sends fourth information to other network devices, the fourth information being used to indicate the reception information of the first signal.

[0229] In this embodiment of the application, different network devices can interact with the first signals of different cells through the interface between network devices. That is, after receiving the first signal in its own cell, a network device can send fourth information to other network devices to indicate the reception status of the first information in its own cell.

[0230] In some embodiments, the received information of the first signal includes one or more of the following:

[0231] Did the network device receive the first signal?

[0232] Information related to the first resource that receives the first signal;

[0233] The measurement results of the first signal;

[0234] Location information of the terminal device that sent the first signal;

[0235] The direction information of the terminal device that sends the first signal.

[0236] In this embodiment, the received information of the first signal can be used to inform other network devices whether there are idle terminal devices in the cell. If so, it reflects the number, location information, and direction information of the idle terminal devices, as well as the summary information of multiple first resources determined based on multiple terminal devices, the measurement results of the first signal, and other information. It should be understood that the received information of the first signal may also include other information, which is not specifically limited here.

[0237] Thus, in this embodiment of the application, network devices exchange reception information of the first signal within the cell through the fourth information, thereby enabling the network devices to more clearly understand the situation of terminal devices in surrounding cells, and thus more reasonably adjust the downlink beam direction to improve efficiency.

[0238] Based on the foregoing embodiments, the signal transmission method and information reception method provided in this application will be described in detail.

[0239] In this embodiment of the application, a UE in the RRC idle state can send HBS when certain conditions are met. By receiving the HBS, the base station can determine whether there are any RRC idle UEs in the cell. If there are, it can further determine one or more of the following information: number of UEs, location, and direction. Thus, the base station can optimize the spatial filter (i.e. downlink beam direction) used for transmitting synchronization signals and broadcast channels, or adjust the transmission period of synchronization signals and broadcast channels.

[0240] The signal transmission method and information reception method provided in the embodiments of this application mainly include the following features:

[0241] Feature 1: A UE in RRC Idle state can send a heartbeat signal (HBS) based on the base station's configuration or triggering signaling. The base station's configuration signaling can be a broadcast message or other RRC layer messages. The base station's triggering signaling can be a broadcast message, other RRC layer messages, or physical layer signaling.

[0242] Feature 2: The HBS (first signal) can use the PRACH sequence format or other sequences. The cyclic prefix length of the HBS should be greater than the cyclic prefix length of the uplink signal sent by the UE in the RRC connection state.

[0243] Feature 3: HBS time and frequency resources are associated with SSB indexes. When the UE actively sends HBS or sends HBS according to the triggering signaling of the base station, it can send it on one or more HBS resources associated with SSB indexes.

[0244] Feature 4: Different base stations can exchange HBS receiving information from different cells through the interface between base stations.

[0245] Thus, using the method of this application embodiment, different base stations can exchange HBS reception information of different cells through the interface between base stations. Through this interaction, the base station can determine whether there are idle UEs in neighboring cells that may reselect to its own cell, thereby allowing for more reasonable adjustment of SSB and broadcast message transmission. The HBS reception information includes one or more of the following: whether an HBS exists in the cell; HBS resource index; and HBS reception strength.

[0246] The following descriptions are based on Examples 1 to 3.

[0247] Example 1: Base station configures HBS resources via static or semi-static signaling

[0248] In this embodiment of the application, the base station can configure HBS resources and / or HBS transmission conditions through broadcast messages or other RRC layer messages. When the conditions are met, the UE in the RRC idle state can transmit HBS.

[0249] Direct HBS Resource Configuration: The base station can directly configure HBS resources (secondary resources) through MIB, SIB1, or other broadcast messages. Direct configuration means including specific parameters in the message indicating the time-frequency location of the HBS resource. This method ensures the flexibility of HBS resource configuration. Preferably, HBS resources are configured within SIB1, which helps reduce the number of broadcast messages the UE needs to receive. The configuration information of HBS resources should at least include the period of the HBS resource and the time-frequency location of one or more HBS resources within each period. If multiple HBS resources exist within a period, they can be sequential in time, avoiding resource fragmentation caused by HBS resources; alternatively, multiple HBS resources can be spaced out in time, providing the base station with time to switch spatial reception filters. The time location of the first HBS resource within a period is indicated with reference to the time location of the configuration message. An example is shown in Figure 5, where HBS resources are configured by SIB1, and there are four HBS resources in each period.

[0250] Indirect HBS resource configuration: The base station can also indirectly configure / indicate HBS resources, for example:

[0251] The base station can configure the time and frequency location of HBS resources without using special parameters. The UE determines the HBS resources through standard predefined rules and reference signals.

[0252] The reference signal can be an SSB or a MIB. For example, the time unit index n of the HBS resource can be m+D, where m is the time unit index of the SSB and D is the standard predefined time interval; while the frequency domain location of the HBS can be a standard predefined uplink transmission resource within the time unit index n.

[0253] In this embodiment of the application, two SSB transmission methods are considered:

[0254] In the first SSB transmission method, the base station transmits SSB burst sets according to a fixed period. The SSBs transmitted in each period have the same structure. Each SSB burst set contains one or more SSBs, and each SSB corresponds to an index. Different SSBs correspond to different downlink spatial filters (downlink beams).

[0255] In the second SSB transmission method, the base station transmits a first type of SSB burst set according to a first cycle and a second type of SSB burst set according to a second cycle. The first cycle is less than or equal to the second cycle. The structures of the first and second SSBs are different. Both the first and second SSB burst sets contain one or more first / second SSBs, and different SSBs correspond to different downlink spatial filters (downlink beams).

[0256] In this application embodiment, there is a correspondence between HBS resources and SSB resources that can be configured directly or indirectly, for example:

[0257] In the direct configuration method, for the first SSB transmission method, the HBS resource period can be equal to the SSB transmission period or an integer multiple of the SSB transmission period. Within each period, the number of HBS resources should be the same as the number of SSB resources in the SSB burst set. There is an association between an HBS resource with a given index and an SSB resource with the same index. This is illustrated in Figure 12 (HBS period and SSB period are the same, one SSB resource corresponds to one HBS resource) and Figure 14 (HBS period and SSB period are different, two SSB resources correspond to one HBS resource).

[0258] In the direct configuration method, for the first SSB transmission method, the HBS resource period can be equal to the SSB transmission period or an integer multiple of the SSB transmission period. Within each period, the number of HBS resources is less than the number of SSB resources in the SSB burst set. There is an association between an HBS resource with a given index and multiple SSB resources with different indices. This is illustrated in Figure 13 (HBS period and SSB period are the same, 2 SSB resources correspond to one HBS resource) and Figure 15 (HBS period and SSB period are different, 4 SSB resources correspond to one HBS resource).

[0259] If using the direct configuration method, in the second SSB transmission method, since the UE can only obtain HBS resource configuration information after decoding the second SSB, the HBS resource period can be equal to or an integer multiple of the second SSB transmission period. Similarly, within each period, the number of HBS resources should be the same as or less than the number of SSB resources in the SSB burst set. See Figure 16 (where the HBS period and the second SSB period are the same, and one SSB resource corresponds to one HBS resource).

[0260] In the indirect configuration method, for the first SSB transmission method, the HBS resource period can be equal to the SSB transmission period. Within each period, the number of HBS resources equals the number of SSB resources in the SSB burst set, and an HBS resource with a given index is associated with SSB resources of the same index. Alternatively, within each period, the number of HBS resources is less than the number of SSB resources in the SSB burst set, and an HBS resource with a given index is associated with multiple SSB resources with different indices.

[0261] In the indirect configuration method, for the second SSB transmission method, the period of the HBS resource can be equal to the second SSB transmission period. Within each period, the number of HBS resources equals the number of second SSB resources in the second SSB burst set, and an HBS resource with a given index is associated with a second SSB resource of the same index. Alternatively, within each period, the number of HBS resources is less than the number of SSB resources in the second SSB burst set, and an HBS resource with a given index is associated with multiple second SSB resources with different indices.

[0262] After the UE obtains the HBS resource configuration, when triggering conditions are met, such as receiving a DCI indication from the base station, it can transmit HBS on one or more HBS resources. These one or more HBS resources must contain at least the HBS resource associated with the SSB with the strongest RSRP. In this way, the base station can determine which SSB direction has a receiving UE.

[0263] The advantage of this embodiment is that the base station can configure HBS resources through static or semi-static signaling, which can avoid introducing complex physical layer signaling and help reduce the complexity of base station scheduling and UE receiving control information.

[0264] Example 2: Configuring HBS Resources via Dynamic Signaling

[0265] In this embodiment, the base station can instruct the HBS on resource configuration via dynamic signaling, such as the configuration DCI carried by the PDCCH. To avoid increasing the power consumption of UE detection of the PDCCH in the RRC idle state, the configuration DCI can only be sent within a specific transmission opportunity, which can be one of the following:

[0266] (1) During the paging opportunity, that is, within the paging opportunity, the UE can detect the configuration DCI in addition to the paging message. The PDCCH carrying the configuration DCI and the PDCCH scheduling the paging can be scrambled with different RNTIs, so that the UE can distinguish between the two.

[0267] (2) During the non-continuous reception activation time, the DRX period, activation time, and non-activation time are configured by the base station through broadcast messages.

[0268] (3) Within the control resource set (CORESET) for scheduling broadcast messages, the broadcast message can be SIB1 or other broadcast messages. Similarly, the scrambled RNTI of the PDCCH carrying the configuration DCI should be different from the scrambled RNTI of the PDCCH carrying the scheduling system message.

[0269] The DCI configuration can directly indicate one or more HBS resources. The number of HBS resources indicated can be equal to or less than the number of SSB resources in the SSB burst set. If it is equal to the number of SSB resources in the SSB burst set, there is an association between an HBS resource with a given index and SSB resources with the same index. If it is less than the number of SSB resources in the SSB burst set, there is an association between an HBS resource with a given index and multiple SSB resources with different indices.

[0270] In this embodiment, if the UE detects the DCI configuration, the UE can transmit HBS on one or more HBS resources, and the one or more HBS resources include at least the HBS resource associated with the SSB with the strongest RSRP. In this way, the base station can determine which SSB direction has a receiving UE.

[0271] The advantage of this embodiment is that the base station can flexibly control the configuration of HBS resources, improve the uplink resource utilization efficiency, and trigger the UE to send HBS while configuring HBS resources, which helps to simplify the control mechanism of the entire HBS.

[0272] Example 3: Configuring HBS resources via static or semi-static signaling and dynamic signaling

[0273] In this embodiment, the base station can jointly configure the resources of the HBS through semi-static signaling, such as MIB or SIB, and dynamic signaling (periodic), such as the configuration DCI (time-domain and frequency-domain) carried by PDCCH.

[0274] To avoid increasing the power consumption of UE detection PDCCH in RRC idle state, DCI is configured to be sent only during specific transmission opportunities, as in Example 2, and will not be repeated here.

[0275] As an example of this embodiment, the base station configures PRACH resource information within the cell via SIB1. If the UE receives the configured DCI at time n, the UE should consider the M PRACH resources after time n+D as HBS resources. Here, D is a standard preset value that can be used by the UE to decode PDCCH. The value of M can be:

[0276] (1) Configured directly or indirectly by a broadcast message, for example, by SIB1 directly indicating the value of M, or by M being equal to the number of SSBs in an SSB burst set indicated in SIB1, or a function of that number. Or,

[0277] (2) As indicated by the DCI configuration.

[0278] In this embodiment, if the UE detects the DCI configuration, the UE can transmit HBS on one or more HBS resources, and the one or more HBS resources include at least the HBS resource associated with the SSB with the strongest RSRP. In this way, the base station can determine which SSB direction has a receiving UE.

[0279] The advantage of this embodiment is that it can take into account the advantages of both Embodiment 1 and Embodiment 2, simplify the design of physical layer signaling, and at the same time ensure a certain degree of flexibility.

[0280] In summary, the embodiments of this application provide a signal transmission method and an information reception method. The network device can determine whether there are idle terminal devices in the cell. If so, it can further obtain information such as the location and number of these terminal devices, thereby optimizing the spatial filter for signal and broadcast channel transmission based on this information of the terminal devices, thereby saving the power consumption of the network device and optimizing the network quality of the terminal devices.
