[0145] The embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine-to-Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication processing methods, and next-generation systems based on them. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G, etc.) for application.

[0146] In some implementations, 5G can meet the user's pursuit of speed, latency, high-speed mobility, energy efficiency, and the communication needs of diversity and complexity of services in future life. The main application scenarios of 5G include enhanced mobile ultra-wideband (Enhanced Mobile Broadband, eMBB), ultra-reliable low latency communications (Ultra-Reliable Low Latency Communications, URLLC), and massive machine type communications (Massive Machine Type Communication, mMTC). Among them, eMBB aims at users to obtain multimedia content, services and data, and its demand is growing rapidly; eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., and its capabilities and requirements are also quite different, and need to be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), traffic safety, etc. Typical characteristics of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of modules, etc.

[0147] In some implementations, 5G base stations consume four times as much energy as LTE base stations, so network energy conservation is an important means to reduce the cost of operating 5G systems.

[0148] In some implementations, in Release 16 (R16), a wake-up signal (WUS) is introduced to realize energy saving of the RRC_CONNECTED terminal in the radio resource control (RRC) connected state. An offset (offset) is defined before the discontinuous reception (Connected DRX, C-DRX) working period (on duration) of the terminal connected state to define the period (duration) for sending the WUS, and the WUS is sent during the period for sending the WUS, that is, the downlink control information (Downlink Control Information, DCI) 2-6, which is encrypted by the power saving RNTI (Power Saving RNTI, PS-RNTI), and is used to indicate whether the terminal wakes up during the next C-DRX onduration to monitor the physical downlink control channel (Physical Downlink Control Channel, PDCCH).

[0149] In some implementations, in R17, a paging WUS is introduced to achieve energy saving of RRC idle or inactive (RRC_IDLE / INACTIVE) terminals. The paging WUS is sent at a certain time before the PO, and the PEI is used to indicate whether the terminal monitors the paging scheduling information at the PO. The PEI is DCI 2-7, which is encrypted by PEI-RNTI.

[0150] In some implementations, in R18, in order to reduce network energy consumption, the network may enter a Network Energy Saving mode (NES mode), and the cell may periodically perform discontinuous transmission (cell DTX) and / or discontinuous reception (cell DRX) at a certain interval. However, in cell DTX or cell DRX, the master information block (MIB), system information block (SIB), paging, and RACH may be sent and received.

[0151] Among them, several NES functions include: reducing synchronization signal blocks (Synchronization Signal PhysicalBroadcast Channel Block, SSB) secondary cells (SSB-less SCell), cell DTX / DRX, antenna port adaptation (Antenna port adaptation), physical downlink shared channel (Physical Downlink Sharedchannel, PDSCH) transmission power adaptation (PDSCH transmission power adaptation).

[0152] In some embodiments, the NES Study Item (SI) may introduce cascaded common channel signal adaptation. The signals may include SSB, signaling radio bearer (SRB) 1, paging, common PDCCH and RACH. The adaptation aspects may be periodicity, time resource locations, omitting of specific signals / channels. The adaptation trigger may be semi-static or dynamic change of transmission.

[0153] In some implementations, RACH adaptation (or PRACH adaptation) includes RACH resource adaptation in the time domain, for example, supporting additional or additional RACH resource configuration. For example, configuring two sets of RACH resource configurations, including the original or conventional (legacy) RACH resource configuration, and the additional RACH resource configuration. The legacy RACH configuration can be broadcasted via SIB1 or configured to the terminal via dedicated signaling.

[0154] Optionally, for PRACH adaptation in the time-domain, the following two are supported:

[0155] The PRACH configuration index of the additional PRACH resource is the same as the PRACH configuration index of the legacy RACH resource (or legacy resources);

[0156] The PRACH configuration index of the additional PRACH resource is different from the PRACH configuration index of the legacy RACH resource.

[0157] Optionally, for PRACH adaptation in the time domain, the frequency domain resources used for additional PRACH resources and legacy RACH resources may be the same or different. The following optional methods may also be referred to:

[0158] Option 1: The following parameters may be configured separately for additional PRACH resources: at least the starting frequency of MSG1 (msg1-FrequencyStart) used for 4-step RACH; or other frequency domain parameters.

[0159] Option 2: configure an offset to a conventional frequency domain parameter for additional PRACH resources. The offset may be a new parameter or other frequency domain parameters.

[0160] In some implementations, RAN1 may dynamically activate or deactivate additional PRACH resource configurations through DCI, for example, by using DCI format 1_0 to send instructions to terminals in an idle state or an inactive state (idle / inactive), and a connected state (connected). For example, additional PRACH resource configurations may be dynamically activated or deactivated through DCI scrambled by a Paging Radio Network Temporary Identifier (P-RNTI), i.e., paging DCI (paging DCI).

[0161] If the activation or deactivation of additional RACH resource configuration is indicated to the terminal through paging DCI, there will be a problem that at least some terminals cannot effectively know the status of additional RACH resource configuration. For example, after the network device sends the paging DCI, the terminal does not receive the paging DCI, or when some terminals select or reselect the cell that has sent the paging DCI, the paging DCI is no longer sent, then the above-mentioned terminal cannot know the activation or deactivation status of the additional RACH resource configuration. In addition, RAN1 discussed the above-mentioned activation or deactivation indicated by paging DCI, but the terminals that can use the additional RACH resource configuration are not clear, and the deactivation method is also not perfect.

[0162] Figure 2 FIG. 1 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. Figure 2 As shown, the embodiment of the present disclosure relates to a communication method, which includes:

[0163] Step S2101, the network device 102 sends first information to the terminal 101.

[0164] In some embodiments, terminal 101 receives first information.

[0165] In some embodiments, the network device 102 may send the first information via different messages or signaling.

[0166] In one example, the first information is sent via a system information block SIB. For example, the network device 102 sends the first information via SIB1 or other SIBs. Optionally, the first information may be sent periodically. After the network device 102 sends the first information once, the terminal 101 that accesses the network device 102 or the cell corresponding to the network device 102 may also receive the first information in other sending periods.

[0167] In another example, the first information is sent via terminal-specific signaling. For example, the network device 102 sends UE-specific RRC signaling to the terminal 101, and the RRC signaling carries the first information. Optionally, the network device 102 may send the first information to the accessed terminal 101 via UE-specific signaling, so that the terminal 101 obtains valid first information.

[0168] In some embodiments, the first information may be configuration information.

[0169] In some embodiments, the first information includes a first RACH resource configuration and indication information, wherein the indication information is used to indicate activation or deactivation information of the first RACH resource configuration.

[0170] In some embodiments, the first RACH resource configuration may be a RACH configuration for RACH adaptation or PRACH adaptation, for example, the first RACH resource configuration is an additional RACH resource configuration.

[0171] Optionally, the legacy RACH resource configuration may be sent through other configuration information other than the first information.

[0172] Optionally, compared with the legacy RACH resource configuration, the first RACH resource configuration can be dynamically enabled or disabled. For example, for a terminal supporting the NES feature or for an R19 terminal, the first RACH resource configuration can be enabled; while for a terminal not supporting the NES feature, the legacy RACH resource configuration can be used and the first RACH resource configuration can be disabled, thereby reducing the number of RACHs received by the network device and improving the energy saving effect of the network device.

[0173] Optionally, the first RACH resource configuration and the legacy RACH resource configuration may overlap in the time domain and / or frequency domain.

[0174] It is worth noting that the relevant implementation methods of RACH adaptation can also refer to the description of the aforementioned embodiment, such as the description of the PRACH adaptation part in the time domain.

[0175] In some embodiments, the indication information may be a parameter defined in the first information, used to indicate information of activation or deactivation of the first RACH resource configuration, such as indicating an activation or deactivation state, and / or indicating time domain information related to activation or deactivation.

[0176] In some embodiments, the indication information includes at least one of the following:

[0177] A first information field, where the first information field is used to indicate an activation or deactivation state of a first RACH resource configuration;

[0178] The second information field is used to indicate the activation duration of the first RACH resource configuration.

[0179] Optionally, the first information field may be a first parameter defined in the first information, used to indicate activation or deactivation of the first RACH resource configuration.

[0180] For example, the first information field or the first parameter uses a 1-bit value to indicate that the first RACH resource configuration is enabled. When the first information field or the first parameter is configured, it indicates activation of the first RACH resource configuration. If the first information field or the first parameter is not configured in the indication information or the first information, it implicitly indicates deactivation of the first RACH resource configuration.

[0181] Alternatively, the first information field or the first parameter adopts a 1-bit value, indicating that the first RACH resource configuration is disabled. When the first information field or the first parameter is configured, it indicates to deactivate the first RACH resource configuration. If the first information field or the first parameter is not configured in the indication information or the first information, it implicitly indicates to activate the first RACH resource configuration.

[0182] For another example, the first information field or the first parameter uses one or more bits, and different values ​​of the field indicate different states. Taking 1 bit as an example, if the value of the 1 bit is the first value or the second value, the first value indicates enabled and the second value indicates disabled, such as (enabled, disabled); or, the first value can be 1 and the second value can be 0, such as (1, 0). When the field is the first value, it indicates activation of the first RACH resource configuration, and when the field is the second value, it indicates deactivation of the first RACH resource configuration. It is worth noting that the first value and the second value can also use other values ​​to indicate the activation or deactivation state of the first RACH resource configuration, which is not limited to this in the embodiments of the present disclosure and will not be elaborated herein.

[0183] For another example, when configuring the first information field or the first parameter, the initial indication is to activate the first RACH resource configuration, that is, the initial state of the first RACH resource configuration is activated. Alternatively, when configuring the first information field or the first parameter, the initial indication is to deactivate the first RACH resource configuration, that is, the initial state of the first RACH resource configuration is deactivated.

[0184] Optionally, the second information field may be recorded as a third parameter, which is used to indicate the activation duration. Optionally, the second information field or the third parameter may also indicate the deactivation duration.

[0185] Optionally, the indication information may include a first information field, and the activation duration is obtained in combination with other information (such as the second information described below). Alternatively, the indication information may include a second information field, and the activation duration is indicated through the second information field and the activation is implicitly indicated. Alternatively, the indication information may include a first information field and a second information field, and indicate the activation or deactivation state and the activation duration to the terminal.

[0186] Step S2102 , the network device 102 sends second information to the terminal 101 .

[0187] In some embodiments, terminal 101 receives second information.

[0188] In some embodiments, the second information may be indication information or dynamic indication information.

[0189] In some embodiments, the second information is used to indicate an activation or deactivation state of the first RACH resource configuration, and / or applicable information.

[0190] Optionally, the second information dynamically indicates activation or deactivation of the first RACH resource configuration.

[0191] Optionally, the second information indicates applicable information of the first RACH resource configuration, such as applicable scenarios or applicable device types.

[0192] Optionally, the second information indicates activation or deactivation of the first RACH resource configuration, and indicates applicable information of the first RACH resource configuration, such as a device type.

[0193] In some embodiments, the second information is sent via paging DCI.

[0194] Among them, paging DCI is DCI format 1_0.

[0195] Optionally, the paging DCI is a DCI scrambled by the P-RNTI, and may be used to paging a terminal, or to indicate a system message change or to perform a system update notification.

[0196] Optionally, the paging DCI may include a short message field (short message) and / or a short message indicator field (short message indicator).

[0197] Optionally, as shown in Table 2-1, the short message indication field is used to indicate whether the paging DCI contains only a short message or only a paging scheduling message. The paging scheduling message is the PDSCH scheduled by the paging DCI, and the PDSCH may include a terminal list (record list). The short message indication field can occupy 2 bits, "00" is a reserved field, "01" indicates that the DCI is only used for paging scheduling, "10" indicates that there is only a short message field in the DCI, and "11" indicates that both the paging scheduling information and the short message exist in the DCI. For "10" and "11", that is, when the paging DCI is used for system information update notification, the short messages field is valid.

[0198] Table 2-1

[0199]

[0200] Optionally, as shown in Table 2-2, the short message field can be used to indicate a system message change. If the short message indication field indicates that there is only a paging scheduling message in the paging DCI, the short message field can be reserved. The short message field can occupy 8 bits.

[0201] Table 2-2

[0202]

[0203] In some embodiments, the second information includes at least one of the following:

[0204] A third information field, where the third information field is used to indicate the activation duration of the first RACH resource configuration;

[0205] A fourth information field, where the fourth information field is used to indicate activation or deactivation of the first RACH resource configuration;

[0206] The fifth information field is used to indicate applicable information, where the applicable information includes a device type to which the first RACH resource configuration is applicable.

[0207] Optionally, the third information field and the second information field may have the same function, and are used to indicate the activation duration, such as being recorded as the third parameter. When the first information includes the second information field, the third information field may not be included in the second information; or the first information does not include the second information field, and the second information includes the third information field. Alternatively, the first information includes the second information field, and the second information also includes the third information field, which is not specifically limited in the embodiments of the present disclosure.

[0208] For example, the duration value of the activation duration is indicated by the second information field, and a timer corresponding to the duration value can be configured. For another example, the duration value of the activation duration is indicated by the third information field, and a timer corresponding to the duration value can be configured. After receiving the relevant information, the terminal can run the timer.

[0209] Alternatively, the activation duration is indicated by the cooperation of the second information field and the third information field. For example, the second information field indicates multiple candidate activation duration values, and the third information field may indicate that one of them is used as the activation duration, and a timer corresponding to the activation duration may be configured. After receiving the second information, the terminal may run the timer.

[0210] Optionally, the fourth information field may be a second parameter, which may be used to dynamically activate or deactivate the first RACH resource configuration in the paging DCI.

[0211] Optionally, the fourth information field is located within or outside the short message field of the second information. For example, the fourth information field is included in the short message field and may occupy one or more bits of the reserved bits (5-8) in the short message field. For another example, the fourth information field does not occupy the reserved bits in the short message field, but occupies other bits outside the short message field in the paging DCI.

[0212] In one example, the second information carries the activation duration of the first RACH resource configuration, for example, the fourth information field in the second information indicates the activation of the first RACH resource configuration, and the activation duration of the first RACH resource configuration is indicated by the third information field. After receiving the second information, the terminal 101 learns the activation of the first RACH resource configuration based on the fourth information field, and the terminal 101 starts the first timer, the value or running duration of the first timer is the activation duration of the first RACH resource configuration (the value of the third information field or the third parameter). If the first timer times out, the terminal 101 determines that the first RACH resource configuration is deactivated.

[0213] Optionally, the fifth information field may be a fourth parameter, which may indicate a device type or a terminal type to which the first RACH resource configuration is applicable.

[0214] In combination with the description of the foregoing embodiment, the second information paging DCI may include a short message domain and / or paging scheduling information, the paging scheduling information is used to schedule a terminal list (record list or paging record list), and the terminal list is used to indicate one or more terminals to be paged. Optionally, the terminal list can be sent via a PDSCH, and the PDSCH is the PDSCH scheduled by the paging DCI.

[0215] Optionally, the device type includes one of the following:

[0216] All terminals that receive the second information, for example, all terminals 101 that receive the paging DCI, may use the first RACH resource configuration in the first information;

[0217] One or more terminals paged in the terminal list, for example, only terminal 101 in the terminal list can use the first RACH resource configuration in the first information.

[0218] In an example, the fifth information field or the fourth parameter is, for example, a 1-bit indicator bit, and the value of the bit may include a third value and a fourth value. When the bit is the third value, it indicates that the first RACH resource configuration can be applied to all terminals that receive the second information. When the bit is the fourth value, it indicates that the first RACH resource configuration can be applied to terminals in the terminal list.

[0219] Optionally, the second information includes a short message field and / or paging scheduling information, and the second information includes a fifth information field.

[0220] For example, when the paging DCI carries both the short message field and the terminal list, the fifth information field needs to be used in the paging DCI to indicate the terminal type to which the first RACH resource configuration is applicable.

[0221] For another example, when the paging DCI carries only paging scheduling information, that is, carries only a terminal list, the paging DCI includes the fifth information field. Alternatively, when the paging DCI carries only a short message field, the paging DCI includes the fifth information field.

[0222] In some embodiments, when sending the second information, the network device 102 may adopt the following method: periodically sending the second information to the terminal 101 in a first period.

[0223] In this embodiment, the terminal 101 that newly accesses the cell corresponding to the network device 102 can also obtain an opportunity to receive the second information.

[0224] Optionally, the first period may be determined by the network device itself, such as determined based on implementation of the network device.

[0225] For example, the first period is determined by the network device according to factors such as network load and the number of terminals.

[0226] For another example, the first cycle is smaller than the paging cycle, or is determined based on the activation duration.

[0227] In some embodiments, the activation or deactivation state of the first RACH resource configuration indicated by the second information takes effect when the terminal receives the second information.

[0228] In this embodiment, if the terminal 101 receives the second information such as paging DCI, it considers that the first RACH resource configuration is activated or deactivated immediately.

[0229] For example, the fourth information field or the second parameter in the paging DCI indicates activation of the first RACH resource configuration, and the terminal 101 receives the paging DCI, and the terminal 101 determines that the first RACH resource configuration is activated immediately. Alternatively, the fourth information field or the second parameter in the paging DCI indicates deactivation of the first RACH resource configuration, and the terminal 101 receives the paging DCI, and the terminal 101 determines that the first RACH resource configuration is deactivated immediately.

[0230] Step S2103: the network device 102 updates the first information based on the second information.

[0231] In some embodiments, if the activation or deactivation state of the first RACH resource configuration is dynamically indicated by paging DCI, the network device 102 may update the first information, such as updating the indication information in the first information.

[0232] Optionally, the network device 102 may update the value of the first information field or the first parameter in the indication information.

[0233] In some embodiments, the first information field in the indication information is associated with the fourth information field.

[0234] Optionally, the value of the first information field or the first parameter is associated with the fourth information field, and may be changed or updated along with the value of the fourth information field, or remain unchanged based on the value of the fourth information field.

[0235] In some embodiments, when the fourth information field indicates activation of the first RACH resource configuration, the first information field is used to indicate that the state of the first RACH resource configuration is activated.

[0236] Optionally, if the initial state of the first information field or the first parameter is to deactivate the first RACH resource configuration, or the first information field or the first parameter indicates deactivation of the first RACH resource configuration before the network device 102 sends the paging DCI, then when the paging DCI is sent, and the fourth information field in the paging DCI dynamically indicates activation of the first RACH resource configuration, the value of the first information field or the first parameter is updated to indicate activation of the first RACH resource configuration.

[0237] Optionally, if the initial state of the first information field or the first parameter is to activate the first RACH resource configuration, or the first information field or the first parameter indicates activation of the first RACH resource configuration before the network device 102 sends the paging DCI, then when the paging DCI is sent, and the fourth information field in the paging DCI dynamically indicates activation of the first RACH resource configuration, the value of the first information field or the first parameter may remain unchanged.

[0238] In one example, if the first information and the second information do not indicate the activation duration, in the first transmission cycle of the first information such as SIB1 after the second information such as paging DCI, or in the last transmission cycle of SIB1 before the paging DCI, the first information field or the first parameter is configured to indicate activation of the first RACH resource configuration. In several transmission cycles after the SIB1, the value of the first information field or the first parameter can remain to indicate activation until the first RACH resource configuration is deactivated, such as dynamically deactivated by new second information such as paging DCI. In this example, in one or more transmission cycles of SIB1 between two paging DCIs, SIB1 carrying indication information can be sent in each transmission cycle, and the first information field or the first parameter is set to activated in each transmission cycle.

[0239] In another example, if the first information or the second information indicates the activation duration, such as the second information field and / or the third information field indicates the activation duration, in one or more sending cycles of the first information such as SIB1 within the activation duration, SIB1 carrying indication information can be sent in each sending cycle, and the first information field or the first parameter is set to activated in each sending cycle.

[0240] In this example, if the fourth information field indicates activation of the first RACH resource configuration, the second information field and / or the third information field is used to indicate: activating the first RACH resource configuration at a first duration. Then the terminal 101 may start a timer corresponding to the first duration, and the first RACH resource configuration remains activated during the timer running time or the first duration.

[0241] In this example, the first RACH resource configuration is deactivated when the timer corresponding to the first duration times out; wherein, when the timer corresponding to the first duration times out, the first information field is used to indicate that the state of the first RACH resource configuration is deactivated. That is, after the timer times out, that is, after the first duration, the first RACH resource configuration becomes deactivated.

[0242] In this example, the first duration is indicated by the second information field and / or the third information field; or, the second information field includes one or more duration values, and the third information field is used to indicate the first duration among the one or more duration values.

[0243] For example, the activation duration is indicated only through the second information field of the first information. If the second information field indicates a duration value, the duration value can be used as the first duration.

[0244] For another example, the activation duration is indicated only through the third information field of the second information. If the third information field indicates a duration value, the duration value can be used as the first duration.

[0245] For another example, the first duration is indicated by configuring the second information field of the first information and the third information field of the second information. Among them, the second information field indicates multiple duration values ​​as candidate values; the third information field indicates one value of the multiple duration values ​​as the first duration. If 8 duration values ​​are indicated in the second information field, each duration value can be indicated by an index; the third information field can occupy 3 bits, and the 3-bit values ​​000-111 correspond to the 8 values ​​in the second information field respectively. The index of a duration value as the first duration can be indicated by the 3-bit value.

[0246] In some embodiments, when the fourth information field indicates deactivation of the first RACH resource configuration, the first information field is used to indicate that the state of the first RACH resource configuration is deactivated.

[0247] In one example, if the initial state of the first information field or the first parameter is to activate the first RACH resource configuration, or the first information field or the first parameter indicates activation of the first RACH resource configuration before the network device 102 sends the paging DCI, then when the paging DCI is sent, and the fourth information field in the paging DCI dynamically indicates deactivation of the first RACH resource configuration, the value of the first information field or the first parameter is updated to indicate deactivation of the first RACH resource configuration.

[0248] In this example, in the first transmission cycle of the first information such as SIB1 after the second information such as paging DCI, or in the last transmission cycle of the SIB1 before the paging DCI, the first information field or the first parameter is configured to indicate deactivation of the first RACH resource configuration, that is, to indicate that the state of the first RACH resource configuration is deactivated. Within several transmission cycles after the SIB1, the value of the first information field or the first parameter can remain to indicate deactivation until the first RACH resource configuration is activated, such as dynamically activated by the paging DCI.

[0249] Optionally, if the initial state of the first information field or the first parameter is to deactivate the first RACH resource configuration, or the first information field or the first parameter indicates deactivation of the first RACH resource configuration before the network device 102 sends the paging DCI, then when the paging DCI is sent, and the fourth information field in the paging DCI dynamically indicates deactivation of the first RACH resource configuration, the value of the first information field or the first parameter may remain unchanged.

[0250] In another example, referring to the above-mentioned first duration, the duration for which the first RACH resource configuration remains in the deactivated state may be determined by configuring or indicating the deactivation duration.

[0251] In some embodiments, when the value of the first information field changes, no system information change indication is sent.

[0252] Optionally, when the value of the first information field or the first parameter associated with the first RACH resource configuration is updated or changed, for example, from indicating activation to indicating deactivation, or from indicating deactivation to indicating activation, the system message change process will not be triggered, and the network device 102 does not need to send a system information change indication.

[0253] Step S2104: Terminal 101 determines whether the activation or deactivation state of the first RACH resource configuration is effective.

[0254] In some embodiments, in combination with the description of the foregoing embodiments, when the terminal 101 receives the second information and the second information is used to indicate activation of the first RACH resource configuration, the terminal determines that activation of the first RACH resource configuration takes effect;

[0255] Alternatively, when the terminal 101 receives the second information and the second information is used to indicate deactivation of the first RACH resource configuration, the terminal determines that deactivation of the first RACH resource configuration is effective.

[0256] In some embodiments, when the terminal 101 is adapted to the first RACH resource configuration, when the first RACH resource configuration is activated, the terminal 101 may initiate a RACH based on the first RACH resource configuration.

[0306] The method in the embodiment of the present disclosure proposes an additional RACH configuration activation or deactivation method, and clarifies the UE type that can use the additional RACH configuration.

[0307] In some embodiments, the additional RACH configuration corresponds to the above-mentioned first additional RACH resource configuration (or referred to as the first additional RACH configuration).

[0308] To facilitate understanding of the embodiments of the present disclosure, some embodiments are listed below.

[0309] Embodiment 1: A first parameter is defined, where the first parameter is used to indicate an activation or deactivation state of a first RACH configuration. See the following Examples 1-1 to 1-5.

[0310] Example 1-1: The first RACH configuration is an additional RACH configuration, and the first parameter is included in the first RACH configuration. The first parameter is used to indicate an activation or deactivation state of the first RACH configuration.

[0311] Exemplarily, the first RACH configuration is configured through a first SIB and / or dedicated RRC signaling. Exemplarily, the first SIB is SIB1 or other SIBs.

[0312] Exemplarily, the first parameter is a 1-bit value, such as enabled, and configuring the first parameter indicates that the first RACH configuration is activated, and not configuring the first parameter indicates that the first RACH configuration is deactivated.

[0313] Exemplarily, the first parameter is a 1-bit value, such as disabled, and configuring the first parameter indicates that the first RACH configuration is deactivated, and not configuring the first parameter indicates that the first RACH configuration is activated.

[0314] Exemplarily, the first parameter takes a first value or a second value, such as (enabled, disabled) or (1, 0). Setting the first parameter to the first value indicates activating the first RACH configuration, and setting the first parameter to the second value indicates deactivating the first RACH configuration.

[0315] Exemplarily, the initial state of the first RACH configuration is activated (the first parameter initially indicates activation). Exemplarily, the initial state of the first RACH configuration is deactivated (the first parameter initially indicates deactivation).

[0316] Example 1-2: The first device (network device) sends a first message (paging DCI) to dynamically activate the first RACH configuration. In the first transmission cycle of the first SIB after the first message or the last transmission cycle of the first SIB before the first message, the first parameter is configured to indicate that the first RACH configuration is activated (the status of the first RACH configuration is activated). In the next few transmission cycles of the first SIB, the value of the first parameter associated with the first RACH configuration remains activated until the first RACH configuration is deactivated.

[0317] In some embodiments, the first message or paging DCI corresponds to the second information in the aforementioned embodiments.

[0318] Example 1-3: The first device (network device) sends a first message (paging DCI) to dynamically deactivate the first RACH configuration. In the first transmission cycle of the first SIB after the first message or the last transmission cycle of the first SIB before the first message, the first parameter is configured to indicate the deactivation of the first RACH configuration (the state of the first RACH configuration is deactivated). In the next few transmission cycles of the first SIB, the value of the first parameter associated with the first RACH configuration remains deactivated until the first RACH configuration is activated.

[0319] Example 1-4: A change in the first parameter associated with the first RACH configuration (eg, from activation to deactivation or from deactivation to activation) does not trigger a system message change procedure.

[0320] Example 1-5: The first network device periodically sends the first message, for example, repeatedly sends the first message at intervals of a first period.

[0321] Exemplarily, the second parameter in the first message is used to dynamically activate and / or deactivate the first RACH configuration. Exemplarily, the second parameter may be included in a short message, for example, the second parameter occupies one or more bits in the reserved bits (5-8) in the short message. Or the second parameter does not occupy the reserved bits in the short message, but occupies other bits in the paging DCI excluding the short message. The paging DCI is DCI format 1_0.

[0322] The second device (UE) receives the first message and considers that the first RACH configuration is activated immediately.

[0323] Optionally, the first period may be determined by the network device itself, such as determined based on implementation of the network device.

[0324] For example, the first period is determined by the network device according to factors such as network load and the number of terminals.

[0325] For another example, the first cycle is smaller than the paging cycle, or is determined based on the activation duration.

[0326] Embodiment 2: defining a third parameter, where the third parameter is used to indicate the activation duration of the first RACH configuration. See the following Example 2-1.

[0327] Example 2-1: The third parameter is included in the first RACH configuration, and the third parameter is used to indicate an activation duration of the first RACH configuration.

[0328] Another possible implementation method is that the third parameter is included in the first message, and the activation duration is indicated by the first message. For example, the first message carries the activation duration of the first RACH configuration. For example, the first message indicates the activation duration of the first RACH configuration at the same time when activating the first RACH configuration.

[0329] The second device receives a first message indicating activation of the first RACH configuration, and the second device starts a first timer, the value of the first timer is the activation duration of the first RACH configuration (the value of the third parameter), and when the first timer times out, the second device determines that the first RACH configuration is to be deactivated.

[0330] Embodiment 3: A fourth parameter is defined, and the fourth parameter is used to indicate the second device type to which the first RACH configuration is applicable. Please refer to the following Examples 3-1 and 3-2.

[0331] Example 3-1: Exemplarily, all second devices that receive the first message can use the first RACH configuration, exemplary, only the second devices in the first list can use the first RACH configuration, exemplary, the first list is used to indicate a list of one or more second devices for paging (paging record list), the first list is sent via PDSCH, and the PDSCH is the PDSCH scheduled for the first message.

[0332] Example 3-2: Exemplarily, the fourth parameter is included in the first message. Exemplarily, the fourth parameter is used to indicate the second device type to which the first RACH configuration is applicable, such as all second devices and / or second devices belonging to the first list.

[0333] As an example, the fourth parameter is a 1-bit indicator bit, and the fourth parameter is set to a third value to indicate that the second device type to which the first RACH configuration applies is all second devices, for example, all second devices that have received the first message, and the fourth parameter is set to a fourth value to indicate that the second device type to which the first RACH configuration applies is a second device in the first list.

[0334] In one embodiment, when the first message carries both the first list and the short message, the first message includes the fourth parameter. In another embodiment, when the first message carries only the first list, the first message includes the fourth parameter. In one embodiment, when the first message carries only the short message, the first message includes the fourth parameter.
