Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a message transmission method and related devices. Background Art

[0002] To save energy when a terminal device is in idle state, the current method is for the network to configure reference signal transmission resources for the terminal device through system broadcast information. That is, the terminal device in idle state can share the reference signal resources with the terminal device in connected state. There are two ways for the terminal device to determine the availability of reference signal transmission resources in idle state:

[0003] One is to determine the availability of reference signal transmission resources by receiving paging early indication (PEI);

[0004] The second is to determine the availability of reference signal transmission resources by receiving paging downlink control information (Paging Downlink Control Information, Paging DCI).

[0091] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0092] The terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0093] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0094] First, the background technology and professional terms in the embodiments of the present application are explained.

[0095] CSI-RS: Channel-State Information Reference Signal;

[0096] TRS: Tracking reference signal, which can be understood as a multi-periodic CSI-RS.

[0097] Paging massage: Paging message, its functions include: (1) sending a call request to the terminal device in the RRC_IDLE state; (2) notifying the terminal device in the RRC_IDLE / INACTIVE and RRC_CONNECTED states that the system information has changed; (3) earthquake and tsunami notification, instructing the terminal device to start receiving ETWS primary notification and / or ETWSsecondary notification; instructing the terminal device to start receiving CMAS notification. If a terminal device is paged or the system information is updated, or an earthquake or tsunami occurs, the base station will first send a wake-up signal. After the terminal device detects the wake-up signal, it will monitor the PDCCH for paging and receive the paging message. Otherwise, the terminal device will remain in the sleep state to save power. In NR, the UE can use discontinuous reception (DRX) in the RRC_IDLE and RRC_INACTIVE states to reduce power consumption. The UE periodically (the paging cycle is the DRX cycle) monitors the paging occasion (Paging Occasion, PO).

[0098] In addition, before receiving Paging, the UE needs to use a reference signal (eg, SSB) to complete time-frequency synchronization and AGC (automatic gain control) adjustment.

[0099] PEI: Paging Early Indication. To save power consumption of terminal devices, in DRX scenarios, each PO can be associated with a PEI. Before monitoring the PO, the terminal device can receive the PEI to determine whether it needs to monitor the PO associated with the PEI, thereby saving power consumption.

[0100] In the eDRX (Extended Idle Mode DRX) scenario, each eDRX cycle has a paging time window (PTW). During the PTW, the terminal device monitors the paging channel according to the DRX cycle (the DRX cycle is short, so the terminal device can be considered to be non-dormant and always reachable) to receive downlink data. The terminal device is in a dormant state during the rest of the time. In other words, in the eDRX (Extended Idle Mode DRX) scenario, a PEI can be associated with multiple POs (assuming m POs). That is, after receiving the PEI indication, the terminal device can determine whether to monitor the subsequent m POs.

[0101] According to the paging rate (10%) of the terminal device group in the existing network, under normal circumstances, there is a probability of more than 90% that the PEI will instruct the terminal device not to wake up at its corresponding PO to monitor the PDCCH.

[0102] The following also introduces the activities of the terminal device in the idle state / inactive state. When idle / inactive, for the measurement of the serving cell, the terminal device basically performs the measurement activity of the serving cell in each DRX cycle. The purpose of the measurement activity is one to reselect the cell, and the other is to complete the time-frequency synchronization and automatic gain control (AGC) adjustment before monitoring PO.

[0103] In the idle / inactive state, before receiving Paging in each DRX cycle, the terminal device needs to use multiple (for example, 3) synchronization signal blocks (SS / PBCH blocks, SSBs) to complete time-frequency synchronization, AGC adjustment, and Radio Resource Management (Radio Resource Management, RRM) measurement for the serving cell. Since SSB is sent periodically (its period size is at the cell level, that is, the SSB transmission period of a cell is the same), it cannot be guaranteed that each PO (the PO period is at the terminal device level, and each terminal device has its own specific PO period) is close to a certain SSB. If the distance between the SSB and the PO is large, the terminal device needs to wake up multiple times to receive paging (here it is assumed that 2 SSBs are required to complete time-frequency synchronization, AGC adjustment, and RRM measurement for the serving cell, then it needs to wake up 3 times, 2 times for time-frequency synchronization / AGC adjustment / serving cell RRM measurement, and 1 time to monitor PO). If the SSB is close to the PO, the terminal device only needs to wake up twice to complete time-frequency synchronization, AGC adjustment, serving cell measurement, and paging reception.

[0104] Furthermore, when the terminal device is in the idle / inactive state, frequent waking up to perform related activities (i.e., time-frequency synchronization, AGC adjustment, and measurement of the serving cell) will increase the power consumption of the terminal device. The current solution of 3GPP is that the network side configures periodic TRS / CSI-RS transmission resources for the terminal device in the idle / inactive state through system broadcast information, that is, the terminal device in the idle / inactive state can share TRS / CSI-RS with the terminal device in the connected state. The terminal device in the idle / inactive state can use TRS / CSI-RS to complete activities such as AGC adjustment / time-frequency synchronization, thereby reducing the number of wake-ups of the terminal device. That is, through TRS / CSI-RS, the terminal device can concentrate time-frequency synchronization, AGC adjustment, and measurement of the serving cell together, thereby reducing the number of times the UE wakes up.

[0105] For example, if Figure 1 As shown, there is an additional reference signal (ARS, also known as TRS / CSI-RS) in front of (and close to) the PO, and the UE only needs to wake up twice to complete time-frequency synchronization, measurement, and Paging reception. However, in the idle / inactive state, the availability of TRS / CSI-RS resources requires the network side to indicate the terminal device, that is, the terminal device needs to determine in advance whether the subsequent TRS / CSI-RS resources are valid (that is, determine whether the base station sends TRS / CSI-RS when the subsequent TRS / CSI-RS is transmitted) by receiving the TRS / CSI-RS validity indication message sent by the network side.

[0106] In order to more flexibly indicate the validity of TRS / CSI-RS, and reduce bit overhead and power consumption of terminal equipment, the embodiment of the present application proposes a message transmission method and related devices, which can dynamically and flexibly indicate the availability of reference signal resources through the joint indication of Paging DCI and PEI, thereby reducing the power consumption and bit overhead of terminal equipment.

[0107] The terminal device in the embodiment of the present application is the UE side, and the access network device is the network side, which will not be repeated here.

[0108] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a mobile communication system provided in an embodiment of the present application. The mobile communication system can be an LTE system or a 5G system, which is also called a New Radio (NR) system, or a next-generation mobile communication technology system of 5G, which is not limited in this embodiment.

[0109] Optionally, the mobile communication system is applicable to different network architectures, including but not limited to relay network architecture, dual-link architecture, vehicle to everything (V2X) architecture, etc.

[0110] The mobile communication system includes: an access network device 220 and a terminal device 240 .

[0111] The access network device 220 may be a base station (BS), also known as a base station device, which is a device deployed in a radio access network (RAN) to provide wireless communication functions. For example, devices providing base station functions in 2G networks include base transceiver stations (BTSs), devices providing base station functions in 3G networks include NodeBs, devices providing base station functions in 4G networks include evolved NodeBs (eNBs), devices providing base station functions in wireless local area networks (WLANs) are access points (APs), and devices providing base station functions in 5G systems are gNBs and further evolved NodeBs (ng-eNBs).

The embodiments of the present disclosure do not limit the specific implementation of the access network device 220. Access network devices may also include home eNBs (HeNBs), relays, pico base stations, and the like.

[0112] A base station controller is a device that manages base stations, such as the base station controller (BSC) in a 2G network, the radio network controller (RNC) in a 3G network, and can also be a device that controls and manages base stations in future new communication systems.

[0113] The network side network (network) in the embodiment of the present disclosure is a communication network that provides communication services for the terminal device 240, including base stations of the wireless access network, and may also include base station controllers of the wireless access network, and may also include equipment on the core network side.

[0114] The core network can be an evolved packet core (EPC), a 5G core network, or a new core network in future communication systems. The 5G core network is composed of a group of devices and implements functions such as the access and mobility management function (AMF), the user plane function (UPF), which provides packet routing and quality of service (QoS) management, and the session management function (SMF), which provides session management, IP address allocation and management. The EPC can be composed of the MME, which provides functions such as mobility management and gateway selection, the Serving Gateway (S-GW), which provides functions such as packet forwarding, and the PDN Gateway (P-GW), which provides functions such as terminal address allocation and rate control.

[0115] Access network device 220 and terminal device 240 establish a wireless connection via a wireless air interface. Optionally, the wireless air interface may be a 5G standard-based wireless air interface, such as NR; or a 5G-based wireless air interface, a next-generation mobile communication network technology standard; or a 4G standard (LTE system). Access network device 220 may receive uplink data sent by terminal device 240 via the wireless connection.

[0116] Terminal device 240 may refer to a device that communicates data with access network device 220.

The terminal device 240 can receive downlink data sent by the access network device 220 through a wireless connection with the access network device 220 .

[0117] One thing that needs to be explained is that when Figure 2 When the mobile communication system shown adopts a 5G system or a next-generation mobile communication technology system of 5G, the above-mentioned network elements may have different names in the 5G system or the next-generation mobile communication technology system of 5G, but have the same or similar functions, and the embodiments of the present disclosure are not limited to this.

[0118] Another point that needs to be explained is that Figure 2 The mobile communication system shown may include multiple access network devices 220 and / or multiple terminal devices 240. Figure 2 Only one access network device 220 and one terminal device 240 are shown for illustration, but this is not limited in the embodiments of the present disclosure.

[0122] The configuration information here can be obtained by receiving system information or RRC signaling from the network side. Each of the above-mentioned transmission resource subsets includes at least one transmission resource. It can be understood that the transmission resources in the embodiment of the present application are TRS / CRI-RS resources or TRS / CRI-RS resource set sets. The above-mentioned duration information may include a first duration T1 or a second duration T2. ​​T1 is an integer multiple of the paging cycle, and the unit of T2 can be a paging cycle, milliseconds, time slots, subframes, frames, etc. There are two message transmission methods according to the different configured duration information, which are not elaborated here. For details, see the description of the subsequent steps.

[0123] By obtaining configuration information, two message receiving methods with valid durations of T1 and T2 can be provided to the terminal device in the reference signal availability indication scenario, thereby improving the flexibility of the reference signal availability indication.

[0124] Step 302: Receive the first message.

[0125] Among them, the above-mentioned first message is used to indicate the first transmission resource subset in the activated state among the at least one transmission resource subset. For example, if the network side configures a transmission resource subsets through configuration information, a is a natural number greater than 1, and there are b first transmission resource subsets in the activated state among the a transmission resource subsets, and b is a natural number less than or equal to a, then the terminal device can determine the b first transmission resource subsets existing in the a transmission resource subsets by receiving the above-mentioned first message.

[0126] Specifically, the above-mentioned first message may include the first bit field information in the paging downlink control information Paging DCI. Further, the first bit field information includes a first bit value, the first bit value represents the value of each bit in the first bit field, each bit in the first bit field has a first mapping relationship with the first transmission resource subset, and the first mapping relationship is indicated by system information or RRC signaling; the first bit field information may also include a first bit field value, the first bit field value represents the value of the first bit field. The terminal device can receive the Paging DCI and read the first bit value or the first bit field value, which is not specifically limited here.

[0127] Furthermore, how the first bit field information indicates whether the transmission resource subset is in an activated state is explained here. It can be understood that the network side can determine the number of bits in the first bit field based on the number of transmission resource subsets, that is, the number of transmission resource subsets is equal to the number of bits in the first bit field. In a possible embodiment, a first mapping relationship can be established between each bit in the first bit field and each transmission resource subset configured by the network side, that is, each bit corresponds to a transmission resource subset. When the bit value is 1, the terminal device can determine that the corresponding transmission resource subset is in an activated state, and the transmission resource subset is the first transmission resource subset; when the bit value is 0, the terminal device can determine that the corresponding transmission resource subset is in an inactivated state, and the transmission resource subset is not the first transmission resource subset. In another possible embodiment, the network side may also directly perform a comprehensive evaluation of the first bit field to obtain the value of the first bit field. For example, if there are three transmission resource subsets, namely C1, C2, and C3, then a value of 00 for the first bit field indicates that all three transmission resource subsets are in an inactive state and that the first transmission resource subset does not exist; a value of 01 for the first bit field indicates that C1 is the first transmission resource subset; a value of 10 for the first bit field indicates that C2 is the first transmission resource subset; and a value of 11 for the first bit field indicates that C3 is the first transmission resource subset. The terminal device may determine the first transmission resource subset of at least one transmission resource subset configured by the network side by reading the value of the first bit field.

[0128] In a possible embodiment, when the configured duration information is T1, the terminal device can receive Paging DCI at the first paging time PO1 to read the first bit value or the first bit field value, and the first paging time PO1 is determined according to the paging parameters and the first duration T1, and the paging parameters include the number of paging frames N in the paging cycle described in the existing protocol, the starting paging frame number PF_offset and the user identifier UE_ID, which are used to determine the paging frame PF and the first paging index i_s, the paging frame represents the system frame number SFN (System Frame Number) corresponding to the first paging time PO1, and the first paging index i_s represents the index of the first paging time in the paging frame.

[0129] The specific steps to determine PO1 are as follows:

[0130] First, determine the PF based on PF_offet, T1, N, and UE_ID, that is, determine the SFN where PO1 is located. The formula is as follows:

[0131] (SFN+PF_offset)mod T1=(T1 div N)*(UE_ID mod N)

[0132] Then, the first paging time index PO1 ndex specifically used for receiving the TRS / CSI-RS availability indication is determined in the PF according to the parameter i_s, and the formula is as follows:

[0133] i_s=floor(UE_ID / N)mod Ns

[0134] in,

[0135] SFN: System Frame Number;

[0136] PF_offset: used in existing protocols to determine the starting time interval of PF, that is, the starting frame number;

[0137] N: the number of PFs in the Paging period in the existing protocol;

[0138] UE_ID: 5G-S-TMSI mod 1024;

[0139] i_s: the index of the determined PO1 in PF (starting from 0);

[0140] T1: TRS / CSI-RS availability indication valid duration T1;

[0141] Ns: the number of POs in a PF.

[0142] Furthermore, the terminal device can receive Paging DCI at PO1 to read the first bit value or the first bit field value, and determine the first transmission resource subset that is activated among all transmission resource subsets configured on the network side based on the first bit value or the first bit field value.

[0143] In a possible embodiment, when the configured duration information is the second duration T2, when a paging DCI is received at any paging time PO and the first bit value or the first bit field value is read, a timer Timer is triggered, and the timing duration of the Timer is equal to T2. It can be understood that the information of the paging DCI within T2 is valid. Once the timer times out, the terminal device needs to re-receive the paging DCI to determine the first transmission resource subset among all transmission resource subsets configured on the network side. The terminal device can receive the paging DCI and read the first bit value or the first bit field value to determine the first transmission resource subset that is activated among all transmission resource subsets configured on the network side. No further details are given here.

[0144] It can be seen that by setting two effective durations and receiving the first message in two ways, the receiving method can be flexibly configured according to the actual scenario, which improves the flexibility of receiving the first message. By first determining the first transmission resource subset in the activated state through paging DCI, the efficiency of subsequent indication of the availability of reference signal resources can be improved, and the bit overhead can be reduced while reducing the power consumption of the terminal device.

[0145] Step 303: Read the second message within the valid time period.

[0146] The second message is used to indicate the availability status of each first transmission resource in the first transmission resource subset. It can be understood that each first transmission resource subset includes at least one first transmission resource, and the first transmission resource is a reference signal TRS / CRI-RS resource or a reference signal TRS / CRI-RS resource set. The availability status can be available or unavailable. The second message may include the second bit field information in the paging advance indication PEI.

[0147] Specifically, the second bit field information includes a second bit value, the second bit value represents the value of each bit in the second bit field, each bit in the second bit field has a second mapping relationship with the first transmission resource in the first transmission resource subset, and the second mapping relationship is indicated by the system information or the RRC signaling; the second bit field information may also include a second bit field value, and the second bit field value represents the value of the second bit field. The terminal device can receive the PEI and read the second bit value or the second bit field value, which is not specifically limited here.

[0148] Furthermore, how the second bit field information indicates the availability status of each first transmission resource in the first transmission resource subset is explained herein. It is understandable that the network side can determine the number of bits in the second bit field based on the number of first transmission resources in each first transmission resource subset, that is, the number of first transmission resources in each first transmission resource subset is equal to the number of bits in the second bit field. In one possible embodiment, a second mapping relationship can be established between each bit in the second bit field and the first transmission resource in each first transmission resource subset, that is, each bit corresponds to a first transmission resource in the first transmission resource subset. When the bit value is 1, the availability status of the corresponding first transmission resource is determined to be available; when the bit value is 0, the availability status of the corresponding first transmission resource is determined to be unavailable. In another possible embodiment, the network side may also directly take the second bit field as a whole to obtain the second bit field value. For example, if a first transmission resource subset includes three first transmission resources, namely s1, s2, and s3, then when the second bit field value is 00, it indicates that the three first transmission resources are unavailable; when the second bit field value is 01, it indicates that s1 is available, s2 and s3 are unavailable; when the second bit field value is 10, it indicates that s2 is available, s1 and s3 are unavailable; when the second bit field value is 11, it indicates that s3 is available, s1 and s2 are unavailable. The terminal device can read the second bit value or the second bit field value within the valid time length to determine the availability status of each first transmission resource in the first transmission resource subset, which will not be repeated here.

[0149] In a possible embodiment, when the duration information is T1, PEI can be received within T1 after PO1 to read the second bit value or the second bit field value and determine the availability of each first transmission resource in the first transmission resource subset.

[0150] For example, if Figure 4A As shown, Figure 4A A schematic diagram of a reference signal availability indication provided in an embodiment of the present application shows that the terminal device receives and reads the Paging DCI at PO1, which indicates that C1 is a first transmission resource subset, and C1 includes two first transmission resources, namely S1 and S2. The terminal device can receive PEI within the effective duration T1 and read the second bit value at this time. When the second bit value is 11, it is determined that both S1 and S2 are available; when the second bit value is 01, it is determined that S1 is unavailable and S2 is available; when the second bit value is 00, it is determined that both S1 and S2 are unavailable.

[0151] like Figure 4B As shown, Figure 4BA schematic diagram of another reference signal availability indication provided for an embodiment of the present application shows that the terminal device receives and reads Paging DCI at PO1, which indicates that C1 and C2 are first transmission resource subsets, C1 includes two first transmission resources, namely S1 and S2, and C2 includes two first transmission resources, namely S3 and S4. The terminal device can receive PEI within the effective duration T1 and read the second bit value at this time to determine the availability of each first transmission resource in C1 and C2. When the second bit value is 11, it is determined that S1 and S2 in C1 are available, and S3 and S4 in C2 are available; when the second bit value is 01, it is determined that S1 in C1 is unavailable, S2 is available, S3 in C2 is unavailable, and S4 is available; when the second bit value is 00, it is determined that S1 and S2 in C1 are unavailable, and S3 and S4 in C2 are unavailable. That is, each first transmission resource subset determines the availability of each first transmission resource in each first transmission resource subset according to the second bit field information in PEI.

[0152] The value of the second bit field can be found in the above method and will not be described in detail here.

[0153] In a possible embodiment, when the duration information is T2, PEI can be received within the timing duration T2 of the timer Timer to read the second bit value or the second bit field value, and determine the availability of each first transmission resource in the first transmission resource subset.

[0154] For example, if Figure 4C As shown, Figure 4C A schematic diagram of another reference signal availability indication provided for an embodiment of the present application shows that the terminal device triggers the timer Timer when any PO receives and reads the Paging DCI, and the Paging DCI indicates that C1 is the first transmission resource subset, and C1 includes two first transmission resources, namely S1 and S2. The terminal device can receive PEI during the Timer operation period, that is, within T2, and read the second bit value at this time. When the second bit value is 11, it is determined that both S1 and S2 are available; when the second bit value is 01, it is determined that S1 is unavailable and S2 is available; when the second bit value is 00, it is determined that both S1 and S2 are unavailable.

[0155] like Figure 4D As shown, Figure 4DA schematic diagram of another reference signal availability indication provided for an embodiment of the present application shows that the terminal device triggers the timer Timer when any PO receives and reads the Paging DCI, and the Paging DCI indicates that C1 and C2 are the first transmission resource subsets, C1 includes two first transmission resources, namely S1 and S2, and C2 includes two first transmission resources, namely S3 and S4. The terminal device can receive PEI during the Timer operation period, i.e., within T2, and read the second bit value at this time. When the second bit value is 11, it is determined that S1 and S2 in C1 are available, and S3 and S4 in C2 are available; when the second bit value is 01, it is determined that S1 in C1 is unavailable but S2 is available, and S3 in C2 is unavailable but S4 is available; when the second bit value is 00, it is determined that S1 and S2 in C1 are unavailable, and S3 and S4 in C2 are unavailable.

[0156] The value of the second bit field can be found in the above method and will not be described in detail here.

[0157] It can be seen that by reading the second message within the valid duration, the reference signal availability indication strategy with two valid durations is also applied. The first message and the second message can be combined to flexibly indicate the availability of each transmission resource, greatly reducing the power consumption and bit overhead of the terminal device.

[0158] The following combination Figure 5 Another message transmission method in the embodiment of the present application is described. Figure 5 A flow chart of another message transmission method provided in an embodiment of the present application, applied to an access network device, specifically includes the following steps:

[0159] Step 501: Send configuration information, a first message, and a second message.

[0160] Among them, the configuration message can be determined through system information or RRC signaling, and the configuration information includes duration information and transmission resource configuration information; the duration information includes a first duration T1 or a second duration T2, which is used to indicate the effective duration of the first message and the effective reading time of the second message; the transmission resource configuration information includes configuration information of at least one transmission resource subset and configuration information of at least one transmission resource contained in each transmission resource subset; the first message is used to indicate the first transmission resource subset in the at least one transmission resource subset that is in an activated state; the second message is used to indicate the availability status of each first transmission resource in the first transmission resource subset, and the first transmission resource is a reference signal resource or a reference signal resource set. It can be understood that the transmission resource in the embodiment of the present application is a TRS / CRI-RS resource or a TRS / CRI-RS resource set.

[0161] Specifically, the first message includes first bit field information in the paging downlink control information Paging DCI, and the second message includes second bit field information in the paging advance indication PEI. The above-mentioned first bit field information may include a first bit value or a first bit field value, and the above-mentioned second bit field information may include a second bit value or a second bit field value.

[0162] In a possible embodiment, the network side may determine the number of bits in the first bit field based on the number of the transmission resource subsets, and then establish a first mapping relationship between each of the transmission resource subsets and the bits in the first bit field, where the first mapping relationship is indicated by the system information or the RRC signaling. In this way, the value of each bit in the first bit field may indicate whether the corresponding transmission resource subset is in an activated state. For example, if the network side configures three reference signal resource sets, namely C1, C2, and C3, the number of bits in the first bit field is determined to be 3, and the first bit is set to correspond to C1, the second bit to correspond to C2, and the third bit to correspond to C3. When the value of a bit is 1, it indicates that the transmission resource subset corresponding to the bit is an activated first transmission resource subset. When the value of a bit is 0, it indicates that the transmission resource subset corresponding to the bit is not activated. For example, if the value of the first bit is 110, it indicates that C1 and C2 are the first transmission resource subset, and C3 is not the first transmission resource subset; for example, if the value of the first bit is 000, it indicates that C1, C2, and C3 are not the first transmission resource subset. I will not go into details here.

[0163] In a possible embodiment, the network side may also directly take the value of the first bit field as a whole to obtain the value of the first bit field. For example, if there are three transmission resource subsets, namely C1, C2, and C3, then when the value of the first bit field is 00, it indicates that the three transmission resource subsets are all in an inactive state and the first transmission resource subset does not exist; when the value of the first bit field is 01, it indicates that C1 is the first transmission resource subset; when the value of the first bit field is 10, it indicates that C2 is the first transmission resource subset; when the value of the first bit field is 11, it indicates that C3 is the first transmission resource subset.

[0164] In one possible embodiment, the network side may determine the number of bits in the second bit field based on the number of first transmission resources in each first transmission resource subset, that is, the number of first transmission resources in each first transmission resource subset is equal to the number of bits in the second bit field. In one possible embodiment, a second mapping relationship may be established between each bit in the second bit field and each first transmission resource, that is, each bit corresponds to a first transmission resource, and when the bit value is 1, the availability status of the corresponding first transmission resource is determined to be available; when the bit value is 0, the availability status of the corresponding first transmission resource is determined to be unavailable.

[0165] In another possible embodiment, the network side may also directly take the second bit field as a whole to obtain the second bit field value. For example, if a first transmission resource subset includes three first transmission resources, namely s1, s2, and s3, then when the second bit field value is 00, it indicates that the three first transmission resources are unavailable; when the second bit field value is 01, it indicates that s1 is available, s2 and s3 are unavailable; when the second bit field value is 10, it indicates that s2 is available, s1 and s3 are unavailable; when the second bit field value is 11, it indicates that s3 is available, s1 and s2 are unavailable. The terminal device can read the second bit value or the second bit field value within the valid time length to determine the availability status of each first transmission resource in the first transmission resource subset, which will not be repeated here.

[0166] It can be seen that through the above method, the first message and the second message can be combined to flexibly indicate the availability of each transmission resource, which greatly reduces the power consumption and bit overhead of the terminal device.

[0167] In order to more clearly illustrate the message transmission method in the embodiment of the present application, Figure 6 Another message transmission method in the embodiment of the present application is described. Figure 6 Another message transmission method provided in an embodiment of the present application is applied to a terminal device and an access network device, that is, a UE side and a network side, and specifically includes the following steps:

[0168] Step 601: Determine configuration information, a first message, and a second message.

[0169] Step 602: Send configuration information, a first message, and a second message.

[0170] Step 603: Obtain configuration information.

[0171] Step 604: Receive a first message.

[0172] Step 605: Read the second message within the valid time period.

[0173] For the above steps not described in detail, please refer to the description of the steps of the aforementioned method and will not be repeated here.

[0174] In a possible embodiment, when the duration information is T1, the corresponding Paging DCI is not received at the first paging moment, or when the corresponding Paging DCI is received at the first paging moment PO1 but the first bit domain information indicates that the first transmission resource subset does not exist in the at least one transmission resource subset, the second bit domain information can be ignored within the first duration T1, and the availability status of the first transmission resource is unavailable.

[0175] In a possible embodiment, when the duration information is T1, when the corresponding Paging DCI is not received at the first paging time, the second transmission resource subset in the activated state in the at least one transmission resource subset can be determined according to the first bit field information in the Paging DCI received at the second paging time. The second paging time PO2 is before the first paging time PO1 and is also determined according to the paging parameter and the first duration. In short, PO2 is the paging time determined in the paging cycle before PO1, which is not repeated here.

[0176] Then, PEI can be received within the first time duration T1 and the second bit value or the second bit field value can be read to determine the availability status of each transmission resource in the second transmission resource subset, where the transmission resource is a reference signal resource or a reference signal resource set.

[0177] In an optional embodiment, when no paging DCI is received after the timer exceeds the second duration, or when a paging DCI is received after the timer exceeds the second duration but the first bit field information indicates that the first transmission resource subset does not exist in the at least one transmission resource subset, the second bit field information is ignored and the availability status of the third transmission resource is unavailable.

[0178] In summary, the message transmission method disclosed in the embodiment of the present application can flexibly indicate the availability of each transmission resource by combining the first message and the second message, thereby greatly reducing the power consumption and bit overhead of the terminal device.
