Typical characteristics of mMTC include high connection density, small data volume, latency-insensitive services, low module cost, and long module lifespan.

[0148] In some implementations, 5G base stations consume four times the energy of LTE base stations, making network energy saving an important means of reducing the cost of operating 5G systems.

[0149] In some implementations, Release 16 (R16) introduces a Wake-Up Signal (WUS) to enable power saving for RRC_CONNECTED terminals in connected Radio Resource Control (RRC) mode. An offset is defined before the on-duration of Connected DRX (C-DRX) in the terminal's connected mode to define the duration of WUS transmission. During this transmission period, WUS, i.e., Downlink Control Information (DCI) 2-6, is transmitted, scrambled with Power Saving RNTI (PS-RNTI), to indicate whether the terminal should wake up and listen to the Physical Downlink Control Channel (PDCCH) during the subsequent C-DRX on-duration.

[0150] In some implementations, R17 introduces paging WUS to power-up terminals in RRC idle or inactive states (RRC_IDLE / INACTIVE). Paging WUS is sent at a certain time before the PO (Point of Purchase), and PEI (Paging Information Indicator) is used to indicate whether the terminal is listening for paging scheduling information at that PO. The PEI is DCI 2-7, scrambled via PEI-RNTI.

[0151] In some implementations, in Release 18 (R18), to reduce network power consumption, the network can enter Network Energy Saving mode (NES mode), where cells periodically perform discontinuous transmission (cell DTX) and / or discontinuous reception (cell DRX) at certain intervals. However, during cell DTX or cell DRX, the Master Information Block (MIB), System Information Block (SIB), paging, and RACH can be transmitted and received.

[0152] Several NES functions include: SSB-less SCell, cell DTX / DRX, antenna port adaptation, and PDSCH transmission power adaptation.

[0153] In some implementations, the NES Study Item (SI) may introduce cascaded common channel signal adaptation. These signals may include SSBs, signalalling radio bearers (SRBs), paging, common PDCCHs, and RACHs. Adaptive aspects may include periodicity, time resource locations, and omitting of specific signals / channels. Adaptive triggering can be semi-static or dynamically altered transmission.

[0154] In some implementations, RACH adaptation (or PRACH adaptation) involves adapting RACH resources in the time domain, for example, supporting additional RACH resource configurations. Taking the configuration of two sets of RACH resource configurations as an example, this includes an existing or legacy RACH resource configuration and an additional RACH resource configuration. The legacy RACH configuration can be broadcast via SIB1 or configured to the terminal via dedicated signaling.

[0155] Optionally, for PRACH adaptation in the time domain, both of the following are supported:

[0156] The PRACH configuration index of additional PRACH resources is the same as that of legacy PRACH resources.

[0157] The PRACH configuration index for additional PRACH resources is different from that for legacy PRACH resources.

[0158] Optionally, for time-domain PRACH adaptation, the frequency domain resources used for additional PRACH resources and legacy RACH resources can be the same or different. The following alternative methods can also be considered:

[0159] Option 1: The following parameters can be configured separately for additional PRACH resources: the start frequency of MSG1 (msg1-FrequencyStart) for at least 4-step RACH; or other frequency domain parameters.

[0160] Option 2: Configure an offset for the traditional frequency domain parameter for the additional PRACH resource. This offset can be a new parameter or another frequency domain parameter.

[0161] In some implementations, RAN1 can dynamically activate or deactivate additional PRACH resource configurations via DCI, for example, by sending indications to terminals in idle / inactive or connected states using DCI format 1_0. This can be achieved by dynamically activating or deactivating additional PRACH resource configurations using DCI scrambled with a Paging Radio Network Temporary Identifier (P-RNTI), i.e., paging DCI.

[0162] If the activation or deactivation of additional RACH resource configuration is indicated to the terminal via paging DCI, at least some terminals may not be able to effectively know the status of the additional RACH resource configuration. For example, if a terminal does not receive the paging DCI after the network device sends it, or if some terminals select or reselect to the cell where the paging DCI was previously sent but is no longer being sent, these terminals will not be able to know the activation or deactivation status of the additional RACH resource configuration. Furthermore, while RAN1 discusses indicating activation or deactivation via paging DCI, the terminals that can use additional RACH resource configuration are not yet clear, and the deactivation method is also incomplete.

[0163] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the present disclosure relates to a communication method, which includes:

[0164] In step S2101, network device 102 sends first information to terminal 101.

[0165] In some embodiments, terminal 101 receives first information.

[0166] In some embodiments, network device 102 may send first information via different messages or signaling.

[0167] In one example, the first information is sent via a System Information Block (SIB). For example, network device 102 sends the first information via SIB1 or another SIB. Optionally, the first information can be sent periodically. After network device 102 sends a first information, a terminal 101 accessing network device 102 or the cell corresponding to network device 102 can also receive the first information in other sending cycles.

[0168] In another example, the first information is sent via terminal-specific signaling. For instance, network device 102 sends UE-specific RRC signaling to terminal 101, which carries the first information. Optionally, network device 102 may send the first information to the accessing terminal 101 using UE-specific signaling, enabling terminal 101 to obtain valid first information.

[0169] In some embodiments, the first information may be configuration information.

[0170] In some embodiments, the first information includes a first RACH resource configuration and indication information, wherein the indication information is used to indicate whether the first RACH resource configuration is activated or deactivated.

[0171] 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.

[0172] Optionally, legacy RACH resource configuration can be sent using configuration information other than the first information.

[0173] Optionally, the first RACH resource configuration can be dynamically enabled or disabled compared to the legacy RACH resource configuration. For example, the first RACH resource configuration can be enabled for terminals that support NES features or for R19 terminals; while for terminals that do not support NES features, 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 network devices and improving the energy efficiency of network devices.

[0174] Optionally, the first RACH resource configuration and the legacy RACH resource configuration may overlap in the time domain and / or frequency domain.

[0175] It is worth noting that related implementations of RACH adaptation can also be found in the description of the foregoing embodiments, such as the description of the RACH adaptation part in the time domain.

[0176] In some embodiments, the indication information may be parameters defined in the first information, used to indicate information on the activation or deactivation of the first RACH resource configuration, such as indicating the activation or deactivation status, and / or indicating time-domain information related to activation or deactivation.

[0177] In some embodiments, the indication information includes at least one of the following:

[0178] The first information field is used to indicate the activation or deactivation status of the first RACH resource configuration.

[0179] The second information field is used to indicate the activation duration of the first RACH resource configuration.

[0180] Optionally, the first information field may be a first parameter defined in the first information, used to indicate whether the first RACH resource configuration is activated or deactivated.

[0181] For example, a first information field or first parameter using a 1-bit value indicates that the first RACH resource configuration is enabled. Configuring this first information field or first parameter indicates activation of the first RACH resource configuration. If the first information field or first parameter is not configured in the indication information or first information, it implicitly indicates deactivation of the first RACH resource configuration.

[0182] Alternatively, the first information field or the first parameter may use a 1-bit value to indicate that the first RACH resource configuration is disabled. Configuring this first information field or the first parameter indicates that the first RACH resource configuration is deactivated. If the first information field or the first parameter is not configured in the indication information or the first information, it implicitly indicates that the first RACH resource configuration is activated.

[0183] For example, the first information field or the first parameter may use one or more bits, and different values ​​of this field indicate different states. Taking 1 bit as an example, if the 1 bit is a first value or a 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 that the first RACH resource configuration is activated, and when the field is the second value, it indicates that the first RACH resource configuration is deactivated. It is worth noting that the first value and the second value can also take other values ​​to indicate the activated or deactivated state of the first RACH resource configuration. This embodiment of the present disclosure does not limit this, nor will it elaborate further.

[0184] For example, when configuring the first information field or the first parameter, the initial indication is to activate the first RACH resource configuration, meaning 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, meaning the initial state of the first RACH resource configuration is deactivated.

[0185] Optionally, the second information field can be designated as the third parameter, used to indicate the activation duration. Optionally, either the second information field or the third parameter can also indicate the deactivation duration.

[0186] Optionally, the indication information may include a first information field, which, in conjunction with other information (such as the second information described below), determines the activation duration. Alternatively, the indication information may include a second information field, which indicates the activation duration and implicitly indicates activation. Alternatively, the indication information may include both a first and a second information field, indicating to the terminal the activation or deactivation status and the activation duration.

[0187] In step S2102, network device 102 sends second information to terminal 101.

[0188] In some embodiments, terminal 101 receives second information.

[0189] In some embodiments, the second information may be indication information or dynamic indication information.

[0190] In some embodiments, the second information is used to indicate the activation or deactivation status of the first RACH resource configuration, and / or applicable information.

[0191] Optionally, the second information dynamically indicates whether to activate or deactivate the first RACH resource configuration.

[0192] Optionally, the second information indicates applicable information for the first RACH resource configuration, such as the applicable scenario or the applicable device type.

[0193] Optionally, the second information indicates whether to activate or deactivate the first RACH resource configuration, and indicates applicable information for the first RACH resource configuration, such as device type.

[0194] In some embodiments, the second information is sent via paging DCI.

[0195] Among them, paging DCI is DCI format 1_0.

[0196] Optionally, the paging DCI is a DCI scrambled by P-RNTI, which can be used for paging terminals or to indicate system message changes or to notify system updates.

[0197] Optionally, the paging DCI may include a short message field and / or a short message indicator field.

[0198] Optionally, as shown in Table 2-1, the short message indication field is used to indicate whether the paging DCI contains only short messages or only paging scheduling messages. 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 the DCI contains only a short message field; and "11" indicates that both paging scheduling information and short messages exist in the DCI. For "10" and "11", that is, when the paging DCI is used for system information update notifications, the short messages field is valid.

[0199] Table 2-1

[0200] Optionally, as shown in Table 2-2, the short message field can be used to indicate system message changes. Specifically, if the short message indication field indicates that only paging scheduling messages exist in the paging DCI, the short message field can be retained. The short message field can occupy 8 bits.

[0201] Table 2-2

[0202] In some embodiments, the second information includes at least one of the following:

[0203] The third information field is used to indicate the activation duration of the first RACH resource configuration;

[0204] The fourth information field is used to indicate whether the first RACH resource configuration is activated or deactivated.

[0205] The fifth information field is used to indicate applicable information, which includes the device type to which the first RACH resource configuration applies.

[0206] Optionally, the third information field and the second information field can have the same function, indicating the activation duration, such as both being denoted as the third parameter. When the first information includes the second information field, the second information may not include the third information field; or the first information does not include the second information field, but 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; this embodiment of the present disclosure does not impose specific limitations.

[0207] For example, the activation duration can be indicated through the second information field, and a timer corresponding to that duration can be configured. As another example, the activation duration can be indicated through the third information field, and a timer corresponding to that duration can be configured. The terminal can run the timer after receiving the relevant information.

[0208] Alternatively, the activation duration can be indicated by combining the second and third information fields. For example, the second information field can indicate the duration values ​​of multiple candidate activation durations, and the third information field can indicate which one to use as the activation duration, and a timer corresponding to that activation duration can be configured. The terminal can run the timer after receiving the second information.

[0209] Optionally, the fourth information field can be a second parameter, which can be used to dynamically activate or deactivate the first RACH resource configuration in paging DCI.

[0210] Optionally, the fourth information field may be located within or outside the short message field of the second information. For example, the fourth information field may be included in the short message field and may occupy one or more of the reserved bits (5-8) in the short message field. Alternatively, the fourth information field may not occupy any reserved bits in the short message field but may occupy other bits outside the short message field in the paging DCI.

[0211] In one example, the second information carries the activation duration of the first RACH resource configuration. For instance, the fourth information field in the second information indicates the activation of the first RACH resource configuration, while the third information field indicates the activation duration of the first RACH resource configuration. After receiving the second information, terminal 101 determines that the first RACH resource configuration is activated based on the fourth information field. Terminal 101 then starts a first timer, the value of which or its duration 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, terminal 101 determines that the first RACH resource configuration is deactivated.

[0212] Optionally, the fifth information field can be a fourth parameter, which can indicate the device type or terminal type to which the first RACH resource configuration applies.

[0213] As described in the foregoing embodiments, the second information paging DCI may include a short message field and / or paging scheduling information. The paging scheduling information is used to schedule a terminal list (record list or paging record list), which indicates one or more terminals being paging. Optionally, the terminal list can be sent via a PDSCH, which is the PDSCH scheduled by the paging DCI.

[0214] Optionally, the device type includes one of the following:

[0215] All terminals that receive the second information, for example, all terminals 101 that receive the paging DCI, can use the first RACH resource configuration in the first information;

[0216] One or more terminals in the terminal list are paged. For example, only terminal 101 in the terminal list can use the first RACH resource configuration in the first information.

[0217] In one example, the fifth information field or fourth parameter is, for example, a 1-bit indicator bit, the value of which can include both a third 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 received 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.

[0218] Optionally, the second information includes a short message field and / or paging dispatch information, and the second information includes a fifth information field.

[0219] For example, when the paging DCI carries both a short message field and a terminal list, the fifth information field in the paging DCI needs to indicate the terminal type applicable to the first RACH resource configuration.

[0220] For example, when the paging DCI only carries paging scheduling information, i.e., only a terminal list, it includes the fifth information field. Or, when the paging DCI only carries the short message field, it includes the fifth information field.

[0221] In some embodiments, when the network device 102 sends the second information, it may do so in the following manner: periodically sending the second information to the terminal 101 in a first cycle.

[0222] In this embodiment, the terminal 101 of the cell corresponding to the newly accessed network device 102 can also have the opportunity to receive the second information.

[0223] Optionally, the first cycle can be determined by the network device itself, such as by the network device implementation.

[0224] For example, the first cycle is determined by the network device based on factors such as network load and the number of terminals.

[0225] For example, the first cycle may be shorter than the paging cycle, or it may be determined based on the activation duration.

[0226] In some embodiments, the activation or deactivation status of the first RACH resource configuration indicated by the second information takes effect when the terminal receives the second information.

[0227] In this embodiment, if terminal 101 receives second information such as paging DCI, it considers that the first RACH resource configuration is immediately activated or deactivated.

[0228] For example, if the fourth information field or the second parameter in the paging DCI indicates activation of the first RACH resource configuration, and terminal 101 receives the paging DCI, terminal 101 determines that the first RACH resource configuration is activated immediately. Alternatively, if the fourth information field or the second parameter in the paging DCI indicates deactivation of the first RACH resource configuration, and terminal 101 receives the paging DCI, terminal 101 determines that the first RACH resource configuration is deactivated immediately.

[0229] In step S2103, network device 102 updates the first information based on the second information.

[0230] In some embodiments, if the activation or deactivation status 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.

[0231] Optionally, the network device 102 may update the value of the first information field or the first parameter in the indication information.

[0232] In some embodiments, the first information field in the indication information is associated with the fourth information field.

[0233] Optionally, the value of the first information field or the first parameter is associated with the fourth information field, and can change or be updated as the value of the fourth information field changes, or remain unchanged based on the value of the fourth information field.

[0234] In some embodiments, when the fourth information field indicates that the first RACH resource configuration is activated, the first information field is used to indicate that the state of the first RACH resource configuration is activated.

[0235] Optionally, if the initial state of the first information field or the first parameter is to deactivate the first RACH resource configuration, or if the first information field or the first parameter indicates to deactivate 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 to activate the first RACH resource configuration, the value of the first information field or the first parameter is updated to indicate to activate the first RACH resource configuration.

[0236] Optionally, if the initial state of the first information field or the first parameter is to activate the first RACH resource configuration, or if the first information field or the first parameter indicates that the first RACH resource configuration is activated 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 that the first RACH resource configuration is activated, the value of the first information field or the first parameter can remain unchanged.

[0237] In one example, if neither the first nor the second information indicates an activation duration, in the first transmission cycle of the first information, such as SIB1, following the second information (e.g., paging DCI), or in the last transmission cycle of SIB1 preceding the paging DCI, the first information field or the first parameter is configured to indicate activation of the first RACH resource configuration. For several transmission cycles following the SIB1, the value of the first information field or the first parameter can remain indicating activation until the first RACH resource configuration is deactivated, such as by a new second information, such as a paging DCI, dynamically deactivating it. In this example, during one or more transmission cycles of SIB1 between two paging DCIs, each transmission cycle can send an SIB1 carrying indication information, and in each transmission cycle, the first information field or the first parameter is set to activation.

[0238] In another example, if the first or second information indicates the activation duration, such as the second information field and / or the third information field indicating the activation duration, in one or more transmission cycles of the first information such as SIB1 within the activation duration, SIB1 carrying indication information can be sent in each transmission cycle, and the first information field or the first parameter is set to active in each transmission cycle.

[0239] In this example, if the fourth information field indicates that the first RACH resource configuration is activated, the second and / or third information fields are used to indicate that the first RACH resource configuration is activated for a first duration. Then, terminal 101 can start a timer corresponding to the first duration, and the first RACH resource configuration remains active during the timer's runtime or within the first duration.

[0240] In this example, the first RACH resource configuration is deactivated when the timer corresponding to the first duration expires; wherein, when the timer corresponding to the first duration expires, the first information field is used to indicate that the state of the first RACH resource configuration is deactivated. That is, after the timer expires, i.e., after the first duration, the first RACH resource configuration becomes deactivated.

[0241] In this example, the first duration is indicated by a second information field and / or a 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 one or more duration values.

[0242] For example, the activation duration can be indicated only by the second information field of the first information. If the second information field indicates a duration value, that duration value can be used as the first duration.

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

[0244] For example, the first duration can be indicated by configuring the second information field of the first information and the third information field of the second information. The second information field indicates multiple duration values ​​as candidate values; the third information field indicates one of these duration values ​​as the first duration. For instance, if the second information field indicates eight duration values, each can be indicated by an index; the third information field can occupy 3 bits, with the values ​​000-111 corresponding to the eight values ​​in the second information field. These 3 bits can then be used to indicate the index of the chosen duration value for the first duration.

[0245] In some embodiments, when the fourth information field indicates that the first RACH resource configuration is deactivated, the first information field is used to indicate that the state of the first RACH resource configuration is deactivated.

[0246] 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 if the first information field or the first parameter indicates to activate 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 to deactivate the first RACH resource configuration, the value of the first information field or the first parameter is updated to indicate to deactivate the first RACH resource configuration.

[0247] In this example, during the first transmission cycle of the first information such as SIB1 after the second information such as paging DCI, or during the last transmission cycle of SIB1 before the paging DCI, the first information field or the first parameter is configured to indicate the deactivation of the first RACH resource configuration, that is, to indicate that the state of the first RACH resource configuration is deactivated. During the several transmission cycles following SIB1, the value of the first information field or the first parameter can remain in a deactivation state until the first RACH resource configuration is activated, such as by dynamic activation via paging DCI.

[0248] Optionally, if the initial state of the first information field or the first parameter is to deactivate the first RACH resource configuration, or if the first information field or the first parameter indicates to deactivate 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 to deactivate the first RACH resource configuration, the value of the first information field or the first parameter can remain unchanged.

[0249] In another example, referring to the first duration method described above, the duration for which the first RACH resource configuration remains inactive can be determined by configuring or indicating the deactivation duration.

[0250] In some embodiments, when the value of the first information field changes, no system information change indication is sent.

[0251] Optionally, when the value of the first information field or the first parameter associated with the first RACH resource configuration is updated or changed, such as 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.

[0252] In step S2104, terminal 101 determines whether the activation or deactivation status of the first RACH resource configuration is effective.

[0253] In some embodiments, in conjunction with the description of the foregoing embodiments, when terminal 101 receives second information and the second information is used to indicate the activation of the first RACH resource configuration, the terminal determines that the first RACH resource configuration is activated and effective.

[0254] Alternatively, when terminal 101 receives the second information and the second information is used to indicate the deactivation of the first RACH resource configuration, the terminal determines that the deactivation of the first RACH resource configuration is effective.

[0255] In some embodiments, when the terminal 101 is applicable to the first RACH resource configuration, when the first RACH resource configuration is activated, the terminal 101 can initiate RACH based on the first RACH resource configuration.

[0299] Figure 3C is an interactive schematic diagram illustrating a communication method according to an embodiment of the present disclosure. As shown in Figure 3C, this embodiment of the present disclosure relates to a communication method, which includes:

[0300] In step S3301, network device 102 sends first information to terminal 101.

[0301] In some embodiments, the implementation of step S3301 can refer to the implementation of step S2101 or step S3101, and will not be repeated here.

[0302] In step S3302, network device 102 sends second information to terminal 101.

[0303] In some embodiments, the implementation of step S3302 can refer to the implementation of step S2102 or step S3201, and will not be repeated here.

[0304] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0305] The method in this disclosure proposes an additional RACH configuration activation or deactivation method, and specifies the UE types that can use additional RACH configuration.

[0306] In some embodiments, the additional RACH configuration corresponds to the first additional RACH resource configuration (or first additional RACH configuration) described above.

[0307] To facilitate understanding of the embodiments of this disclosure, some embodiments are listed below.

[0308] Example 1: Define a first parameter, which indicates the active or deactivated state of the first RACH configuration. See Examples 1-1 to 1-5 below.

[0309] Example 1-1: This first RACH configuration is an additional RACH configuration, and the first parameter is included in this first RACH configuration. This first parameter is used to indicate the active or deactivated state of the first RACH configuration.

[0310] For example, the first RACH configuration is configured via a first SIB and / or dedicated RRC signaling, and for example, the first SIB is SIB1 or another SIB.

[0311] For example, the first parameter is a 1-bit value, such as enabled. Configuring the first parameter indicates that the first RACH configuration is activated, while not configuring the first parameter indicates that the first RACH configuration is deactivated.

[0312] For example, the first parameter is a 1-bit value, such as disabled. Configuring the first parameter indicates that the first RACH configuration is deactivated, while not configuring the first parameter indicates that the first RACH configuration is activated.

[0313] For example, the first parameter can take the value of a first value or a second value, such as (enabled, disabled) or (1, 0). Setting the first parameter to the first value indicates that the first RACH configuration is activated, and setting the first parameter to the second value indicates that the first RACH configuration is deactivated.

[0314] For example, the initial state of the first RACH configuration is active (the first parameter initially indicates active), and the initial state of the first RACH configuration is deactivated (the first parameter initially indicates deactivated).

[0315] 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 in 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 state of the first RACH configuration is active). In the next few transmission cycles of the first SIB, the value of the first parameter associated with the first RACH configuration remains active until the first RACH configuration is deactivated.

[0316] In some embodiments, the first message or paging DCI corresponds to the second message in the foregoing embodiments.

[0317] 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 in 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 deactivated (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.

[0318] Example 1-4: A change in the first parameter associated with the first RACH configuration (e.g., from active to deactivated or from deactivated to active) will not trigger the system message change process.

[0319] Example 1-5: The first network device periodically sends the first message, for example, it repeatedly sends the first message at a first interval.

[0320] For example, the second parameter in the first message is used to dynamically activate and / or deactivate the first RACH configuration. This second parameter can be included in a short message; for instance, it may occupy one or more bits from the reserved bits (5-8) in the short message. Alternatively, the second parameter may not occupy reserved bits in the short message but instead occupy other bits in the paging DCI excluding the short message. The paging DCI is DCI format 1_0.

[0321] Upon receiving the first message, the second device (UE) considers the first RACH configuration to be activated immediately.

[0322] Optionally, the first cycle can be determined by the network device itself, such as by the network device implementation.

[0323] For example, the first cycle is determined by the network device based on factors such as network load and the number of terminals.

[0324] For example, the first cycle may be shorter than the paging cycle, or it may be determined based on the activation duration.

[0325] Example 2: Define a third parameter, which indicates the activation duration of the first RACH configuration. See Example 2-1 below.

[0326] Example 2-1: The third parameter is included in the first RACH configuration and is used to indicate the activation duration of the first RACH configuration.

[0327] Another possible implementation 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 as activating the first RACH configuration.

[0328] The second device receives a first message indicating that the first RACH configuration is activated. The second device starts a first timer, the value of which is the activation duration of the first RACH configuration (the value of the third parameter). When the first timer expires, the second device determines that the first RACH configuration is deactivated.

[0329] Example 3: Define a fourth parameter, which indicates the second device type applicable to the first RACH configuration. See Examples 3-1 to 3-2 below.

[0330] Example 3-1: Exemplarily, all second devices that receive the first message can use the first RACH configuration, exemplarily only the second devices in the first list can use the first RACH configuration, exemplarily the first list is used to indicate a list of one or more second devices being paged (paging record list), the first list is sent via PDSCH, the PDSCH scheduled for the first message.

[0331] Example 3-2: For example, the fourth parameter is included in the first message, and for example, the fourth parameter is used to indicate the second device type to which the first RACH configuration applies, such as all second devices and / or second devices belonging to the first list.

[0332] As an example, the fourth parameter is a 1-bit indicator bit. The fourth parameter is set to the third value to indicate that the second device type to which the first RACH configuration applies is all second devices, such as all second devices that received the first message. The fourth parameter is set to the fourth value to indicate that the second device type to which the first RACH configuration applies is the second device belonging to the first list.

[0333] In one embodiment, when the first message carries both a first list and a 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 a short message, the first message includes the fourth parameter.

[0334] This disclosure also provides an apparatus for implementing any of the above methods. For example, an apparatus is provided that includes units or modules for implementing the steps performed by the terminal in any of the above methods.
