Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining."

[0054] First, the relevant technologies involved in the embodiments of this application are introduced:

[0055] With the increasing demand for speed, latency, high-speed mobility, and energy efficiency, coupled with the increasing diversity and complexity of future communications services, the 3rd Generation Partnership Project (3GPP), an international standards organization, has begun developing fifth-generation mobile communication technology (5G). The primary application scenarios for 5G are enhanced mobile broadband (eMBB), ultra-reliable low-latency communication (URLLC), and massive machine-type communication (mMTC).

[0056] eMBB still aims to provide users with multimedia content, services, and data, and demand for this technology is growing rapidly. However, since eMBB can be deployed in diverse scenarios, such as indoors, in urban areas, and in rural areas, its capabilities and requirements vary significantly. Therefore, it cannot be generalized and requires detailed analysis based on specific deployment scenarios. Typical applications of URLLC include industrial automation, power automation, remote medical operations (surgery), and traffic safety. Typical characteristics of mMTC include high connection density, small data volumes, latency-insensitive services, low module costs, and long service life.

[0057] New Radio (NR) can also be deployed independently. To reduce air interface signaling and quickly restore wireless connections and data services in 5G networks, a new Radio Resource Control (RRC) state, the RRC_INACTIVE state, has been defined. This state is different from the RRC_IDLE and RRC_ACTIVE states.

[0058] RRC_IDLE: Mobility is based on cell reselection by the user equipment (UE). Paging is initiated by the core network (CN), and the paging area is configured by the CN. There is no UE access stratum (AS) context on the base station side. No RRC connection exists.

[0059] RRC_CONNECTED: An RRC connection exists, and a UE AS context exists between the eNodeB and the UE. The network knows the UE's location at the cell level. Mobility is controlled by the network. Unicast data can be transmitted between the UE and the eNodeB.

[0060] RRC_INACTIVE: Mobility is based on UE cell selection and reselection. There is a connection between CN and NR. The UE AS context exists on a certain base station. Paging is triggered by the Radio Access Network (RAN). The RAN-based paging area is managed by the RAN. The network side knows the UE location based on the RAN paging area level.

[0061] Bandwidth Part (BWP) Technology

[0062] To provide higher data rates and enhance user experience, 5G NR further increases the system bandwidth compared to 4G. In 5G NR, the maximum bandwidth supported by a single carrier is 100MHz for frequency bands below 6GHz, and 400MHz for frequency bands above 6GHz. For a large carrier bandwidth, such as 100MHz, the bandwidth required by a terminal is often very limited. Forcing the terminal to perform detection and measurement across the entire bandwidth would pose a significant challenge to terminal power consumption and hinder power conservation. Therefore, 5G NR introduces the concept of Bandwidth Workload (BWP). This allocates a contiguous portion of bandwidth within the entire large-bandwidth carrier for terminal data transmission and reception. The terminal only needs to perform operations within this portion of bandwidth allocated by the network, thus achieving energy conservation.

[0063] Based on the relevant 5G NR standards, for each service cell of the terminal, the network can configure one or more BWPs for the terminal on this service cell through the RRC reconfiguration message, and the maximum number of configurable BWPs is 4. At each moment, the terminal can only have 1 activated downlink (Downlink, DL) BWP and 1 activated uplink (Uplink, UL) BWP on this service cell, and the terminal can only send and receive data on the activated BWP. Taking into account factors such as the diversity of terminal services and the differences in different service characteristics, the terminal may need to adjust the BWP. For example, when the terminal has a large amount of business and hopes to obtain high-speed services, a large-bandwidth BWP is required to transmit data for this terminal. When the terminal has a small amount of business, a small-bandwidth BWP can be used for data transmission for this terminal. The BWP activated by the terminal on this service cell can be changed by BWP switching. The following 4 BWP switching methods are currently supported in the relevant standards:

[0064] 1. BWP switching based on the Physical Downlink Control Channel (PDCCH)

[0065] Network-controlled BWP switching: The network notifies a single terminal of the target BWP to switch to by sending a PDCCH scrambled with a Cell-Radio Network Temporary Identifier (C-RNTI) to the terminal.

[0066] 2. BWP switching based on RRC (re)configuration

[0067] Network-controlled BWP switching: By carrying firstActiveDownlinkBWP-Id and / or firstActiveUplinkBWP-Id in the RRC (re)configuration message, the terminal is instructed to switch the active BWP to firstActiveDownlinkBWP-Id and / or firstActiveUplinkBWP-Id.

[0068] 3. BWP switching based on timer timeout

[0069] This is an implicit BWP switching method. The network side configures a timer bwp-InactivityTimer for each serving cell of the terminal. If the DL BWP currently activated by the terminal is a BWP other than the default BWP and the initial DL BWP, each time the terminal receives a PDCCH indicating the uplink or downlink scheduling of the UE on the currently activated BWP, or the terminal receives a PDCCH indicating the uplink or downlink scheduling of the UE on the currently activated BWP, the timer bwp-InactivityTimer is started or restarted. When the timer bwp-InactivityTimer times out, the terminal automatically switches to the default BWP or initial DL BWP, where the default BWP and initial BWP are both determined by the RRC configuration.

[0070] 4. BWP switching caused by random access initialization

[0071] During the Random Access Channel (RACH) initialization process, if the terminal does not configure a Physical Random Access Channel (PRACH) occasion on the currently activated UL BWP, the terminal automatically switches the UL BWP to the initial UL BWP and simultaneously switches the DL BWP to the initial DL BWP.

[0072] System message update

[0073] In Long Term Evolution (LTE) and NR systems, the concept of system message update cycle is used. When the network wants to update the system message, the network first repeatedly sends the system message update indication in the nth system message update cycle, and then repeatedly sends the changed system message in the n+1th system message update cycle. The boundary of the system message update cycle is defined as the SFN that satisfies the system frame number (SFN) mod m = 0, where m is the number of SFNs included in a system message update cycle (Modification Period, MP). m = modificationPeriodCoeff*defaultPagingCycle, where modificationPeriodCoeff and defaultPagingCycle are the system message update cycle coefficient and the default paging cycle, respectively. These two parameters are determined by network broadcast. The schematic diagram of system message update is shown in Figure 1.

[0074] In the NR system, the system message update period applies to updates of system messages other than System Information Block (SIB) 6, SIB7, SIB8, and positioning assistance data. In NR, the short message in the paging downlink control information (DCI) is used to notify the system information update indication. The PDCCH containing the paging DCI is scrambled by the paging RNTI (Paging-RNTI).

[0075] If the value of systemInfoModification in the short message is 1, it means that system information other than SIB6, SIB7, and SIB8 needs to be updated. The terminal then obtains the updated system information in the next system information update period.

[0076] If the value of etwsAndCmasIndication in the short message is 1, indicating that the network is sending an Earthquake and Tsunami Warning System (ETWS) and / or Commercial Mobile Alert System (CMAS) notification, the terminal immediately re-reads SIB1, SIB6, SIB7, and SIB8 after receiving the short message.

[0077] Conditional Handover (CHO)

[0078] In response to the problems of frequent handovers and easy handover failures in high-speed mobility scenarios and high-frequency deployment scenarios, LTE and NR systems in related technologies have introduced a handover process based on conditional triggering, as shown in Figure 2. The basic principle is that the base station allocates the target cell to the terminal in advance (201), and includes the conditions for triggering the UE to perform handover in the HO command (203). When the UE evaluates the conditional trigger related to the target cell according to the conditions configured on the network side, it executes handover to the target cell according to the pre-configured handover command (204), that is, triggering the random access process and sending a handover completion message, thereby avoiding the problem of not being able to send measurement reports or receive handover commands in time due to high-speed movement into a poor coverage area.

[0079] For CHO, the network can configure multiple candidate target cells in the handover command (HO command) and configure CHO execution conditions for each candidate target cell. Each CHO execution condition can include one or two triggering events. Related art uses events A3 and A5 for CHO, and A4 is also accepted as a CHO event. The terminal determines which target cell to access based on the configured CHO execution conditions.

[0080] Currently, the measurement events supported in NR include the following:

[0081] A1 event: The signal quality of the serving cell exceeds a threshold;

[0082] A2 event: The signal quality of the serving cell falls below a threshold;

[0083] A3 event: The signal quality of the neighboring cell exceeds the signal quality of the special cell (SpCell) by a threshold.

[0084] A4 event: The signal quality of the neighboring cell exceeds a threshold;

[0085] A5 event: The signal quality of the SpCell is lower than a threshold 1, and the signal quality of the neighboring cell is higher than a threshold 2;

[0086] A6 event: The signal quality of the neighboring cell is higher than the signal quality of the secondary cell (SCell) by a threshold.

[0087] B1 event: The signal quality of a neighboring cell with a different technology exceeds a threshold;

[0088] B2 event: The signal quality of the primary cell (PCell) is lower than a threshold 1, and the signal quality of the heterogeneous technology neighboring cell is higher than a threshold 2.

[0089] Conditional PSCell Change (CPC)

[0090] To address the frequent PSCell changes in high-speed mobility and high-frequency deployment scenarios, related technologies have introduced a condition-triggered PSCell change process for LTE and NR systems. The basic principle is that the Secondary Node (SN) pre-assigns the target cell to the terminal, including the conditions for triggering the terminal to perform a PSCell change. The terminal then evaluates the conditions configured by the network and initiates a PSCell change when the conditions are met. This avoids the problem of being unable to send measurement reports or receive PSCell change commands in time due to high-speed movement into poor coverage areas.

[0091] Similar to CHO, for CPC, the network can configure multiple candidate target cells for the terminal and configure CPC execution conditions for each candidate target cell. Each CPC execution condition can include one or two triggering events. Related art uses A3 and A5 events for CPC events. The terminal determines which target cell to access based on the configured CPC execution conditions.

[0092] Network energy saving project

[0093] Energy consumption has become a significant component of operators' operating costs. According to relevant reports, mobile network energy costs account for approximately 23% of operators' total costs. The majority of energy consumption comes from the radio access network, particularly the active antenna unit (AAU), while data centers and fiber optic transmission only contribute to a smaller share. Radio access network power consumption consists of two types:

[0094] Dynamic part: such as the consumption during data transmission / reception;

[0095] Static portion: This includes the consumption required to maintain the operation of the wireless access device, even when there is no ongoing data transmission / reception.

[0096] Network energy conservation project research should not only assess potential network energy savings but also evaluate and balance the impact on network and user performance. For example, this research should not significantly impact key performance indicators (KPIs), such as spectrum efficiency, capacity, user perceived throughput (UPT), latency, terminal power consumption, complexity, handover performance, call drop rate, and initial access performance.

[0097] However, current research focuses primarily on terminal energy-saving technologies, without considering network energy conservation. Furthermore, there is no discussion on how related technologies like CHO and BWP switching can support or integrate with network energy conservation technologies.

[0098] Therefore, the present application proposes an energy-saving method and studies network energy-saving technology. The energy-saving method proposed in the present application is described below through exemplary embodiments.

[0290] Step 720: Obtain network status or network configuration;

[0291] Network status includes base station status or cell status;

[0292] Among them, the base station status includes: the status of the base station corresponding to the service cell of the terminal, the status of the base station corresponding to the main cell of the terminal, the status of the base station corresponding to the main and auxiliary cells of the terminal, the status of the adjacent base stations of the base station corresponding to the service cell of the terminal, the status of the adjacent base stations of the base station corresponding to the main cell of the terminal, the status of the adjacent base stations of the base station corresponding to the main and auxiliary cells of the terminal, and at least one of the status of the base stations in the ANR list.

[0295] In some embodiments, the network state is an implicit network state, that is, the network indicates the network energy-saving technology or network energy-saving configuration to be used, and the network energy-saving technology or network energy-saving configuration corresponds to the corresponding network state. For example, the network indicates an extended parameter configuration, which corresponds to a DTX state, a DRX state, or a medium load state; or the network indicates that data and / or signaling and / or system information are transmitted according to the first configuration, which corresponds to a DTX state, a DRX state, or a medium load state; or the network indicates that data and / or signaling and / or system information are not transmitted, which corresponds to a network shutdown state.

[0299] Step 740: Perform data transmission and / or signaling transmission and / or system information transmission according to the network configuration or network status or network status change;

[0300] In some embodiments, data transmission and / or signaling transmission and / or system information transmission are performed according to network configurations; at least one of the network configurations is related to network energy saving.

[0301] In some embodiments, data transmission and / or signaling transmission and / or system information transmission are performed according to a network state, at least one of the network states being related to network energy saving.

[0302] In some embodiments, data transmission and / or signaling transmission and / or system information transmission are performed according to a network state change, and at least one state in the changed network state is related to network energy saving.

[0303] In some embodiments, the network status may be two or more, such as: network on / network off, network on / network off / DRX / DTX, low load / medium load / high load status.

[0304] In some embodiments, the terminal performs data transmission and / or signaling transmission and / or system information transmission when instructed or enabled by the network, and at least one piece of information in the network instruction or enablement is related to network energy saving.

[0305] In some embodiments, a data and / or signaling transmission and / or system information transmission method is determined based on a network status change indication or information.

[0306] In some embodiments, performing data transmission and / or signaling transmission and / or system information transmission according to a network state includes at least one of the following:

[0307] When instructed by the network, the terminal performs data transmission and / or signaling transmission and / or system information transmission according to the network status;

[0308] When the terminal reports auxiliary information, data transmission and / or signaling transmission and / or system information transmission are performed according to the network status.

[0309] In some embodiments, when the network indicates a network status or a status change to the terminal, data transmission and / or signaling transmission and / or system information transmission is performed according to the network status or network status change indication.

[0310] In some embodiments, performing data transmission and / or signaling transmission and / or system information transmission according to a network state includes at least one of the following:

[0311] When the network is closed, no data transmission and / or signaling transmission and / or system information transmission is performed;

[0312] When the network is closed, perform data transmission and / or signaling transmission and / or system information transmission according to the first configuration;

[0313] When the network is shut down, data transmission and / or signaling transmission and / or system information transmission are performed according to the DTX / DRX configuration of the network;

[0314] When the network is turned on, perform data transmission and / or signaling transmission and / or system information transmission;

[0315] When the network is turned on, data transmission and / or signaling transmission and / or system information transmission are performed according to the default configuration;

[0316] When network DTX is turned on, data transmission and / or signaling transmission and / or system information transmission are performed (as shown in FIG8 );

[0317] When network DTX is turned off, data transmission and / or signaling transmission and / or system information transmission are not performed (as shown in FIG8 );

[0318] When network DTX is turned off, perform data transmission and / or signaling transmission and / or system information transmission according to the first configuration;

[0319] In case of network DTX, performing data transmission and / or signaling transmission and / or system information transmission according to the first configuration;

[0320] It can be understood as: performing data transmission and / or signaling transmission and / or system information transmission in the DTX on state, or enlarging the interval of data transmission and / or signaling transmission and / or system information transmission, that is, "performing data transmission at cell DTX on state or enlarge the data transmission interval".

[0321] When network DRX is enabled, data transmission and / or signaling transmission and / or system information transmission are performed (as shown in FIG8 );

[0322] When network DRX is turned off, data transmission and / or signaling transmission and / or system information transmission are not performed (as shown in FIG8 );

[0323] When network DRX is disabled, perform data transmission and / or signaling transmission and / or system information transmission according to the first configuration;

[0324] In case of network DRX, performing data and / or signaling transmission and / or system information transmission according to the first configuration;

[0325] The first configuration is a configuration related to network energy saving, or the first configuration is a configuration with an extended interval compared to a default configuration.

[0326] It can be understood as: performing data transmission and / or signaling transmission and / or system information transmission in the DRX on state, or enlarging the interval of data transmission and / or signaling transmission and / or system information transmission, that is, "performing data transmission at cell DRX on state or enlarge the data transmission interval".

[0327] If the cell shutdown mechanism is enabled, we understand that no data transmission should occur when the cell is shut down. From the UE's perspective, when the UE becomes aware of the cell shutdown information or receives a data transmission disable indication, it can cease data transmission. If the mechanism for reducing / adapting transmission / reception opportunities is enabled, we understand that discontinuous transmission is permitted. For example, the UE can use specific durations for data transmission, such as when the UE receives a cell DRX / DTX configuration or an extended signaling configuration, to transmit data in DTX / DRX mode or using an extended data transmission interval.

[0328] The UE should be informed of this configuration or cell on / off status to align with the network's intention. This configuration or cell on / off status can be sent through dynamic signaling (e.g., RRC / DCI signaling) or semi-static configuration (e.g., configuration mode). Therefore, the UE can rely on this network information to operate data transmission.

[0329] That is, "If the cell off mechanism is enabled, we understand that there should be no data transmitted during the cell off situation. From the UE perspective, the UE can stop data transmission when it knows the cell off information or receives the data transmission disabling indication. If the reduced / adapted transmission / reception occasion mechanism is enabled, we understand that discontinuous transmission is allowed. For example, the UE can transmit data using a certain duration, e.g., performing data transmission in DTX / DRX mode or using an enlarged data transmission interval when the UE receives a cell DRX / DTX configuration or an enlarged signaling configuration."

[0330] the UE should be informed with such configuration or the cell on / off situation to align with the network intention. Such configuration or the cell on / off situation can be sent via dynamic signaling (egRRC / DCI signaling) or a semi-static configuration (ega configured pattern). Accordingly, the UE can rely on this kind of network information to operate the data transmission."

[0331] Step 760: Obtain updated network status or updated network configuration.

[0332] The updated network status includes an updated base station status or an updated cell status;

[0333] Among them, the updated base station status includes: the status of the base station corresponding to the service cell of the updated terminal, the status of the base station corresponding to the main cell of the updated terminal, the status of the base station corresponding to the main and auxiliary cells of the updated terminal, the status of the adjacent base stations of the base station corresponding to the service cell of the updated terminal, the status of the adjacent base stations of the base station corresponding to the main cell of the updated terminal, the status of the adjacent base stations of the base station corresponding to the main and auxiliary cells of the updated terminal, and at least one of the statuses of the base stations in the updated ANR list.

[0334] The updated cell status includes: the status of the service cell of the updated terminal, the status of the main cell of the updated terminal, the status of the main and auxiliary cells of the updated terminal, the status of the neighboring cell of the updated terminal, the status of the cell of the adjacent base station of the updated base station, and at least one of the status of the cell of the base station in the updated ANR list.

[0335] In some embodiments, the updated network status may include at least one of the following: cell network on indication, cell network off indication, base station network on indication, base station network off indication, cell identifier, base station identifier, cell DTX indication, base station DTX indication, cell DRX indication, base station DRX indication, base station network on information, base station network off information (as in the embodiment corresponding to Figure 5 or Figure 6), cell network on information, cell network off information, base station DRX configuration, base station DTX configuration, cell DRX configuration, cell DTX configuration (as in the embodiment corresponding to Figure 5 or Figure 6), cell network sleep, cell network non-sleep, base station network sleep, base station network non-sleep, cell network normal transmission, base station network normal transmission, cell network DRX status, base station network DRX status, cell network DTX status, base station network DTX status, the first level load status among at least two levels of load status, the second level load status among at least two levels of load status, and the third level load status among at least two levels of load status.

[0336] In some embodiments, the updated network state is an implicit network state, that is, the network indicates the network energy-saving technology or network energy-saving configuration to be used, and the network energy-saving technology or network energy-saving configuration corresponds to the corresponding updated network state. For example, the network indicates an extended parameter configuration, corresponding to a DTX state, a DRX state, or a medium-load state; or the network indicates that data and / or signaling and / or system information are transmitted according to the first configuration, corresponding to a DTX state, a DRX state, or a medium-load state; or the network indicates that data and / or signaling and / or system information are not transmitted, corresponding to a network shutdown state.

[0337] In some embodiments, the updated network status is an implicit network status, that is, information transmitted / sent / received by the network, including data and / or signaling and / or system information.

[0338] In some embodiments, the network state is an implicit network state, that is, an updated RRC configuration message, or the network updates the RRC configuration.

[0339] Exemplarily, the network configuration parameter includes at least one of the configuration parameters in RRC dedicated signaling and / or public signaling.

[0340] Exemplarily, the network configuration may be an RRC message carrying at least one of the following configurations, such as CG configuration, SPS configuration, PUSCH configuration, PDSCH configuration, SR configuration, PRACH configuration, RACH configuration, PUCCH configuration, PDCCH configuration, SIB configuration, Master Indication Block (MIB) configuration, reference signal configuration, search space configuration, DRX configuration, DTX configuration, DG configuration, SSB configuration, and the like.

[0341] For example, it indicates a change in the cell situation, such as cell off. When switching to cell off, we understand there should be no data transmitted during the cell off situation. From the UE perspective, the UE can stop data transmission when it knows the cell off information or receives the data transmission disabling indication. For example, it indicates an updated network configuration, such as an extended transmission interval or triggered DRX / DTX. When switching to an extended transmission interval or triggered DRX / DTX, we understand that discontinuous transmission is allowed. For example, the UE can transmit data using a certain duration, eg, performing data transmission in DTX / DRX mode or using an enlarged data transmission interval when the UE receiving a cell DRX / DTX configuration or an enlarged signaling configuration.

[0342] The UE should be informed with such configuration or the cell on / off situation to align with the network intention. Such configuration or the cell on / off situation can be sent via dynamic signaling (egRRC / DCI signaling) or a semi-static configuration (eg configured pattern). Accordingly, the UE can rely on this kind of network information to operate the data transmission.

[0343] In some embodiments, the data and / or signaling and / or system information includes at least one of the following:

[0344] Public information or signaling;

[0345] Terminal-specific information or signaling or data.

[0362] This can be understood as: performing data transmission and / or signaling transmission and / or system information transmission in the DRX on state, or enlarging the interval of data transmission and / or signaling transmission and / or system information transmission.

[0612] In some embodiments, when a Configured Grant (CG) period is configured with a non-integer period or non-integer parameter, a Physical Uplink Shared Channel (PUSCH) opportunity is calculated based on a first formula, wherein the parameter related to the CG period in the first formula is rounded up or down.

[0613] In some embodiments, when a semi-persistent scheduling (SPS) period is configured with a non-integer period or non-integer parameter, a physical downlink shared channel (PDSCH) opportunity is calculated based on a second formula, wherein the parameter related to the SPS period in the second formula is rounded up or down.

[0614] In summary, the method provided in this embodiment enables the network to perform operations related to network energy saving, thereby achieving the purpose of network energy saving.

[0615] An exemplary embodiment of the present application provides a PUSCH / PDSCH opportunity calculation formula.

[0616] The calculation method for the non-integer configuration PUSCH / PDSCH opportunity provided in this embodiment is used to transmit data of a certain service, which can be network energy saving, or a service related to network energy saving, or other services independent of network energy saving. Among them, the PUSCH / PDSCH opportunity can be one PUSCH / PDSCH opportunity or multiple PUSCH / PDSCH opportunities. The relevant calculation method of the PUSCH / PDSCH opportunity calculation formula provided in this embodiment can be used independently of the network energy saving technology (for example, for a specific service or a specific scenario independent of the network energy saving technology), and can also be used together with the network energy saving technology.

[0617] When a CG period is configured with a non-integer period or non-integer parameter, the PUSCH opportunity is calculated based on the first formula;

[0618] When an SPS period is configured with a non-integer period or non-integer parameter, the PUSCH opportunity is calculated based on the second formula;

[0619] Among them, the parameters related to the CG period in the first formula are rounded up or rounded down, and the parameters related to the SPS period in the second formula are rounded up or rounded down.

[0620] In some embodiments, parameters related to the CG period or SPS period include at least one of the following: N, period, symbol length, number of time slots in each frame, position of the first PDSCH transmission initiated by SPS, and position of the first PUSCH transmission initiated by SPS.

[0621] Optionally, the position of the first PDSCH transmission of the SPS initialization includes at least one of: the SFN of the first PDSCH transmission (i.e., the SFN at which the PDSCH transmission starts), the time slot of the first PDSCH transmission (i.e., the time slot at which the PDSCH transmission starts), and the symbol of the first PDSCH transmission (i.e., the symbol at which the PDSCH transmission starts);

[0622] The position of the first PUSCH transmission initially transmitted by SPS includes at least one of: the SFN of the first PUSCH transmission (i.e., the SFN at which the PUSCH transmission starts), the time slot of the first PUSCH transmission (i.e., the time slot at which the PUSCH transmission starts), and the symbol of the first PUSCH transmission (i.e., the symbol at which the PUSCH transmission starts).

[0623] In some embodiments, parameters related to the CG period include: N*first period, or N*first period plus the position of the first PUSCH transmission at the beginning of the CG period. N represents the Nth CG period or the Nth PUSCH opportunity or the first PUSCH opportunity in the Nth CG period. The first period is related to the SPS period and the symbol length.

[0624] Optionally, the first PUSCH opportunity in the Nth CG cycle may be the first PUSCH opportunity that occurs; it may also be a specific PUSCH opportunity, configured by the network device, or indicated by the network device, or predefined by the communication protocol; it may also be a PUSCH opportunity determined by a rule, which is configured by the network device, or indicated by the network device, or predefined by the communication protocol.

[0625] In some embodiments, parameters related to the SPS period include: N*second period, or N*second period*number of slots in each frame divided by 10, or N*second period plus the position of the first PDSCH transmission at the beginning of the SPS, or N*second period*number of slots in each frame divided by 10 plus the position of the first PDSCH transmission at the beginning of the SPS. Wherein, N represents the Nth SPS period or the nth PDSCH opportunity or the first PDSCH opportunity in the Nth SPS period, and the second period is related to the SPS period and the symbol length.

[0626] Optionally, the first PDSCH opportunity in the Nth SPS cycle can be the first PDSCH opportunity that occurs; it can also be a specific PDSCH opportunity, configured by the network device, or indicated by the network device, or predefined by the communication protocol; it can also be a PDSCH opportunity determined by a rule, which is configured by the network device, or indicated by the network device, or predefined by the communication protocol.

[0627] In some embodiments, the first period is equal to the CG period divided by the duration of each symbol, or the period of each packet divided by the duration of each symbol, or the configured period;

[0628] And / or, the second period is equal to the SPS period divided by the duration of each symbol, or the period of each packet divided by the duration of each symbol, or the configured period.

[0629] Optionally, the first period and / or the second period may be related to a service period or a packet rate or a non-integer service period.

[0630] Optionally, the first period and / or the second period may be represented by a non-integer (for example, with a decimal part) or a fraction.

[0631] Optionally, the first period and / or the second period is equal to the service period or packet rate or non-integer service period, or may be a variant of the service period or packet rate or non-integer service period (for example, one using fps, one using ms / symbol, etc.), or may be a reduction of the service period or packet rate or non-integer service period (for example, a fraction or decimal or a non-carry number (integer or decimal) or a carry number (integer or decimal)).

[0632] For example, in CG type 1:

[0633] After configuring uplink grants for CG type 1, the Media Access Control (MAC) entity shall consider the Nth (N>=0) uplink grant appearing in the following symbols in sequence:

[0634] After an uplink grant is configured for a configured grant Type 1, the MAC entity shall consider sequentially that the Nth(N>=0)uplink grant occurs in the symbol for which:

[0635] [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]=

[0636] (timeReferenceSFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot

[0637] +timeDomainOffset×numberOfSymbolsPerSlot+S+ceiling{N×periodicity})

[0638] modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)

[0639] or,

[0640] [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]=

[0641] (ceiling{timeReferenceSFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot

[0642] +timeDomainOffset×numberOfSymbolsPerSlot+S+N×periodicity})

[0643] modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)

[0644] Wherein, SFN is the system frame number; numberOfSlotsPerFrame is the number of time slots in each frame; numberOfSymbolsPerSlot is the number of symbols in each time slot; slot number in the frame is the time slot number in the frame; symbol number in the slot is the symbol number in the time slot; timeReferenceSFN is the time domain reference SFN, which is used to determine the SFN offset of the resource in the time domain; timeDomainOffset is the resource offset in the time domain with SFN=0; S is the starting symbol; ceiling indicates rounding up; periodicity = the configured period value divided by the duration of each symbol (e.g., several milliseconds), or periodicity = the duration of each packet (e.g., a set of Protocol Data Units (PDUs), a burst period) divided by the duration of each symbol, or the configured period value.

[0645] Optionally, the first period and / or the second period may be related to a service period or a packet rate or a non-integer service period.

[0646] Optionally, the first period and / or the second period may be represented by a non-integer (for example, with a decimal part) or a fraction.

[0647] Optionally, the first period and / or the second period is equal to the service period or packet rate or non-integer service period, or may be a variant of the service period or packet rate or non-integer service period (for example, one using fps, one using ms / symbol, etc.), or may be a reduction of the service period or packet rate or non-integer service period (for example, a fraction or decimal or a non-carry number (integer or decimal) or a carry number (integer or decimal)).

[0648] The above calculation method is an exemplary calculation method for rounding up. The case of rounding down can be represented by floor.

[0649] In CG Type 2:

[0650] After configuring uplink grants for CG type 2, the MAC entity shall consider the Nth (N>=0) uplink grant appearing in the following symbols in sequence:

[0651] After an uplink grant is configured for a configured grant Type 2, the MAC entity shall consider sequentially that the Nth(N>=0)uplink grant occurs in the symbol for which:

[0652] [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]=

[0653] [(SFN start time ×numberOfSlotsPerFrame×numberOfSymbolsPerSlot

[0654] +slotstart time×numberOfSymbolsPerSlot+symbolstart time)+ceiling{N×periodicity}]

[0655] modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)

[0656] or,

[0657] [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame× numberOfSymbolsPerSlot)+symbol number in the slot]=

[0658] [ceiling{(SFN start time ×numberOfSlotsPerFrame×numberOfSymbolsPerSlot

[0659] +slotstart time×numberOfSymbolsPerSlot+symbolstart time)+N×periodicity}]

[0660] modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)

[0661] Among them, SFN start time Indicates the SFN of the first transmission of PUSCH, slotstart time indicates the time slot of the first transmission of PUSCH, and symbolstart time indicates the symbol of the first transmission of PUSCH.

[0662] Optionally, the periods in the above CG Type 1 and CG Type 2 are in millisecond level, or in units of frames per second (FPS), or expressed in fractions, or at symbol level, or expressed in non-integer (for example, with a decimal part).

[0663] The above calculation method is an exemplary calculation method for rounding up. The case of rounding down can be represented by floor.

[0664] Optionally, the calculation formula corresponding to the CG position may also adopt a calculation formula similar to that of SPS to calculate the position of CG PUSCH.

[0665] For example, in Option 1 of SPS (rounding up):

[0666] After configuring downlink allocations for SPS, the MAC entity shall consider the Nth downlink allocation to occur in the following time slots in sequence:

[0667] (numberOfSlotsPerFrame×SFN+slot number in the frame)=

[0668] [(numberOfSlotsPerFrame×SFN start time +slotstart time)+ceiling{N×periodicity×numberOfSlotsPerFrame / 10}]modulo(1024×numberOfSlotsPerFrame)

[0669] or,

[0670] (numberOfSlotsPerFrame×SFN+slot number in the frame)=

[0671] [ceiling{(numberOfSlotsPerFrame×SFN start time +slotstart time)+N×periodicity×numberOfSlotsPerFrame / 10}]modulo(1024×numberOfSlotsPerFrame)

[0672] Among them, SFN start time The slotstart time represents the time slot of the first transmission of the PDSCH, in which the configured downlink allocation is (re)initialized.

[0673] where SFN start time and slotstart time are the SFN and slot, respectively, of the first transmission of PDSCH where the configured downlink assignment was (re-)initialised.

[0674] In SPS option 2 (round down):

[0675] After configuring downlink allocations for SPS, the MAC entity shall consider the Nth downlink allocation to occur in the following time slots in sequence:

[0676] (numberOfSlotsPerFrame×SFN+slot number in the frame)=

[0677] [(numberOfSlotsPerFrame×SFN start time +slotstart time)+floor{N×periodicity×numberOfSlotsPerFrame / 10}]modulo(1024×numberOfSlotsPerFrame)

[0678] or,

[0679] (numberOfSlotsPerFrame×SFN+slot number in the frame)=

[0680] [floor{(numberOfSlotsPerFrame×SFN start time +slotstart time)+N×periodicity×numberOfSlotsPerFrame / 10}]modulo(1024×numberOfSlotsPerFrame)

[0681] Among them, SFN start time The slotstart time represents the time slot of the first transmission of the PDSCH, in which the configured downlink allocation is (re)initialized.

[0682] Optionally, periodicity can be the second period, or a configured period.

[0683] Optionally, the configured period value may be related to a service period or a packet rate or a non-integer service period.

[0684] Optionally, the configured period value can be expressed as a non-integer (for example, with a decimal part) or a fraction.

[0685] Optionally, the configured or used period value is equal to the service period or packet rate or non-integer service period, or it can be a variant of the service period or packet rate or non-integer service period (for example, one using fps, one using ms / symbol, etc.), or it can be a reduction of the service period or packet rate or non-integer service period (for example, a fraction or decimal or a non-carry number (integer or decimal) or a carry number (integer or decimal)).

[0686] Optionally, the period in the above SPS is in millisecond level, or in units of frames per second (Frame Per Second, FPS), or expressed in fractions, or in symbol level, or expressed in non-integer.

[0687] Optionally, the following is an example of a CG / SPS calculation formula (the difference from the previous one is whether there are square brackets or parentheses):

[0688] ·SPS PDSCH:

[0689] (numberOfSlotsPerFrame×SFN+slot number in the frame)=

[0690] ceiling{[(numberOfSlotsPerFrame×SFNstart time+slotstart time)+N×periodicity×numberOfSlotsPerFrame / 10]}modulo(1024×numberOfSlotsPerFrame)

[0691] The periodicity supported by SPS is {100 / 3ms, 50 / 3ms, 100 / 9ms, 25 / 3ms}.

[0692] That is, The periodicities supported for SPS are{100 / 3ms,50 / 3ms,100 / 9ms,25 / 3ms}.

[0693] CG Type 1:

[0694] [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]=

[0695] ceiling{(timeReferenceSFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+timeDomainOffset×numberOfSymbolsPerSlot+S+N×periodicity)}modulo(1024×numberOfSlotsPerFrame× numberOfSymbolsPerSlot)

[0696] CG Type 2:

[0697] [(SFN×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)+(slot number in the frame×numberOfSymbolsPerSlot)+symbol number in the slot]=

[0698] ceiling{[(SFNstart time×numberOfSlotsPerFrame×numberOfSymbolsPerSlot+slotstart time×numberOfSymbolsPerSlot+symbolstart time)+N×periodicity]}modulo(1024×numberOfSlotsPerFrame×numberOfSymbolsPerSlot)

[0699] In addition, in the network configuration, there may be multiple CG / SPS periods corresponding to one service, logical channel, or transmission, or multiple CG / SPS configurations corresponding to one service period (i.e., one service period has resource locations corresponding to multiple CG / SPS configurations), or multiple CG / SPS configurations have the same period but different resource configuration sizes and / or starting positions. This situation can occur in a network energy-saving environment or be independent of network energy-saving (i.e., there is no coupling relationship with network energy-saving).

[0700] When there are multiple PUSCH / PDSCH opportunities, when there are multiple PUSCH / PDSCH transmission opportunities corresponding to one service, or multiple CG / SPS (so there will be multiple PUSCH / PDSCH opportunities) are used to transmit one service, or there are multiple CG / SPS periods corresponding to one service or logical channel or transmission, or multiple CG / SPS configurations corresponding to one service period (i.e., one service period has resource locations corresponding to multiple CG / SPS configurations), or when multiple CG / SPS configurations have the same period but different resource configuration sizes and / or starting positions, the terminal or network can indicate whether some opportunities are used or canceled, or the terminal or network can indicate which CG / SPS configuration or configurations (or PUSCH / PDSCH opportunities) are activated and / or deactivated. Further, it may include at least one of the following:

[0704] · Indicates the location or identity of the opportunity(s) being used or cancelled;

[0705] Indicated by one of MAC CE, RRC, CG-UCI, SR, UCI, DCI, and DL DG-DCI (DG carries indication information);

[0706] Indicated by a specific opportunity in a cycle, such as the first one, the first N (N can be 1) opportunities used or cancelled, or the first X, where X is a positive integer;

[0707] The partially used or cancelled opportunity may be, for example, the last one, the last Y opportunities, where Y is a positive integer.

[0708] Optionally, the above indication may be in the first or a specific one or several opportunities or CG / SPS index indications, or in the currently activated or used opportunity or CG / SPS index indications.

[0709] Optionally, the resources or resource sizes of multiple CGs / SPSs in one cycle or the resources or resource sizes configured by multiple CGs / SPSs may be the same or different.

[0710] Optionally, the resources or resource sizes of multiple CG / SPSs within a cycle or the resources or resource sizes configured by multiple CG / SPSs correspond to different business data transmission requirements or business data volume transmission requirements or packet sizes or data rates.

[0711] Optionally, the resources or resource sizes of multiple CG / SPSs within a period or the resources or resource sizes configured by multiple CG / SPSs are the same, and at least part of the multiple CG / SPSs are used together for service transmission, or specific service transmission, or logical channel (LCH) transmission, or data transmission.

[0712] Optionally, the resources or resource sizes of multiple CG / SPSs within one period or the resources or resource sizes configured by multiple CG / SPSs are different, one of the CG / SPSs is used for service transmission or specific service transmission or LCH transmission or data transmission, or at least part of the multiple CG / SPSs are used together for service transmission or specific service transmission or LCH transmission or data transmission.

[0713] In some embodiments, the packet arrival rate is {30, 60, 90, 120} fps, and its service period should correspond to {33.33, 16.67, 11.11, 8.33} ms. Accordingly, the CG / SPS period is {33.33, 16.67, 11.11, 8.33} ms. In other words, there are no restrictions on the CG / SPS period configuration. In this case, the CG / SPS position calculated using the ceiling or floor formula can be considered, and the calculated result may have a transmission position deviation.

[0714] In some embodiments, the packet arrival rate is {30, 60, 90, 120} fps, and its service period should correspond to {33.33, 16.67, 11.11, 8.33} ms. Accordingly, for 33.33ms, 11.11ms, and 8.33ms, the CG / SPS period is {33.33, 11.11, 8.33} ms, while the CG / SPS period corresponding to 16.67ms is limited to 16.66ms. That is, there is no restriction on the CG / SPS period for 33.33ms, 11.11ms, and 8.33ms, but there should be a restriction on the CG / SPS period of 16.67ms. Otherwise, the CG / SPS position calculated using rounding formulas such as rounding up or rounding down will have deviations, which is not conducive to service transmission. Furthermore, when the decimal point of the value corresponding to the service period is greater than 0.5, the CG / SPS configuration of the service period needs to be restricted (i.e., the decimal point is retained and no rounding is performed). In other embodiments, consideration is given to whether to perform rounding on the service period after considering the symbol, or on the CG / SPS period after considering the symbol. For example, consideration is given to whether to perform rounding on the period, or to whether to perform rounding on the value obtained by dividing the period by the symbol duration.

[0715] In some embodiments, the packet arrival rate is {30, 60, 90, 120} fps, and its service period should correspond to {33.33, 16.67, 11.11, 8.33} ms. Correspondingly, the CG / SPS period is {33.33, 16.67, 11.11, 8.33} ms. In other words, there is no restriction on the CG / SPS period configuration. In this case, it is possible to consider using the rounding formula of rounding up + rounding down to calculate the CG / SPS position to avoid deviation in the transmission position and ensure service transmission. For example, the following conditions can be used to determine whether to use the rounding up or rounding down operation. For example: if the condition satisfies N mod M = 0, the rounding down calculation formula is used, otherwise the rounding up formula is used. Wherein, N is the value of N used when calculating the current position in the CG / SPS opportunity calculation formula, or N is the Nth CG / SPS opportunity after the starting CG / SPS position or period, or N is the value of the Nth position corresponding to the CG / SPS configuration minus 1). Among them, M is the denominator corresponding to fps (for example, 60fps is 50 / 3, and the denominator is 3).

[0716] An example of a possible calculated CG / SPS position is shown in Figure 23. When the packet arrival rate is 60fps, the service cycle is 16.67 (1000 / 60) ms. If the round-up calculation method is used, the opportunity positions of the SPS PDSCH at positions such as 0ms, 17ms, 34ms, and 50ms can be calculated as shown in Figure 23. If the round-down calculation method is used, the opportunity positions of the SPS PDSCH can be calculated as positions such as 0ms, 16ms, 33ms, and 50ms. The CG / SPS position calculated in another calculation method can be the opportunity position of the SPS PDSCH at positions such as 0ms, 17ms, 34ms, and 51ms. The calculated position of the CG is the same as this, or similar (such as considering the symbol factor).

[0717] In some embodiments, for XR services or for non-integer service cycles (such as packet arrival rates of {30, 60, 90, 120} fps, the service cycle should correspond to {33.33, 16.67, 11.11, 8.33} ms), the CG / SPS pattern configuration method can also be used to configure the transmission resources or locations of XR services or services with non-integer cycles. Optionally, the CG / SPS pattern configuration is periodic. The CG / SPS pattern configuration method can be independent of network energy-saving technology (for example, for specific services or specific scenarios that are independent of network energy-saving technology), and can also be used together with network energy-saving technology.

[0718] Optionally, multiple PUSCH / PDSCH transmission opportunities are configured in each or a specific CG / SPS mode. The multiple PUSCH / PDSCH transmission opportunities are discontinuous transmission opportunities.

[0719] Optionally, for the PUSCH / PDSCH transmission opportunity, the interval between a certain transmission opportunity and the most recent previous transmission opportunity is constant (except for the interval between the last two transmission opportunities).

[0720] At least one of the CG / SPS mode configuration, the CG / SPS mode period, the interval between transmission opportunities, and the number of transmission opportunities for each CG / SPS mode is related to at least one of the service period, service arrival time, and data (service packet) size. For example, for DL ​​60fps XR video service, the SPS mode configuration period is 50ms. Within each SPS mode, 3 SPS-PDSCH transmission opportunities can be configured, and the interval between each SPS transmission opportunity and the most recent SPS-PDSCH transmission opportunity before it is 17ms (except for the interval between the last two SPS-PDSCH transmission opportunities).

[0721] A possible CG / SPS pattern is shown in Figure 23. When the packet arrival rate is 60 fps, the service period is 16.67 (1000 / 60) ms. If the round-up calculation method is used, the SPS PDSCH opportunity positions at positions such as 0ms, 17ms, 34ms, and 50ms can be calculated as shown in Figure 23. If the round-down calculation method is used, the SPS PDSCH opportunity positions can be calculated as positions such as 0ms, 16ms, 33ms, and 50ms. The CG / SPS positions calculated in another calculation method can be SPS PDSCH opportunity positions at positions such as 0ms, 17ms, 34ms, and 51ms. The calculation position of the CG is the same as this, or similar (such as considering the symbol factor).

[0722] Optionally, for the period-related content of this application, such as at least one of the non-integer period, XR period, fractional period, period in the fps identification mode, and period with decimal places, the final configuration used can be configured during RRC configuration or MAC use, and / or an equivalent definition for the configuration use can be executed. (For example, for CG / SPS)

[0723] For example: RRC configuration:

[0734] For example, it is stated in the MAC or RRC configuration:

[0735] periodicityExt2

[0736] This field is used to calculate the periodicity for UL transmission without UL grant for type 1 and type 2 (see TS 38.321[3], clause 5, 8.2). If this field is present, the fields periodicity and periodicityExt are ignored. The used is periodicityExt2 divided by the symbol length associated with the configured BWP SCS.

[0737] Or,

[0738] This field is used to calculate the periodicity for UL transmission without UL grant for type 1 and type 2 (see TS 38.321[3], clause 5, 8.2). The used is periodicityExt2 divided by the symbol length associated with the configured BWP SCS.

[0739] Or,

[0740] The following periodicities are supported for CG depending on the configured subcarrier spacing[symbols]:

[0741] ·{100 / 3 / 14,50 / 3 / 14,100 / 9 / 14,25 / 3 / 14}for 15kHz;

[0742] ·0.5x{100 / 3 / 14,50 / 3 / 14,100 / 9 / 14,25 / 3 / 14}for 30kHz;

[0743] ·0.25x{100 / 3 / 14,50 / 3 / 14,100 / 9 / 14,25 / 3 / 14}for 60kHz with normal CP;

[0744] ·0.25x{100 / 3 / 12,50 / 3 / 12,100 / 9 / 12,25 / 3 / 12}for 60kHz with ECP;

[0745] ·0.125x{100 / 3 / 14,50 / 3 / 14,100 / 9 / 14,25 / 3 / 14}for 120kHz;

[0746] ·0.0625x{100 / 3 / 14,50 / 3 / 14,100 / 9 / 14,25 / 3 / 14}for 480kHz;

[0747] ·0.03125x{100 / 3 / 14,50 / 3 / 14,100 / 9 / 14,25 / 3 / 14}for 960kHz.

[0748] In some embodiments, when the terminal is a transmitting end, segmentation is performed on the first data packet at the SDAP layer or the PDCP layer; when the terminal is a receiving end, reassembly is performed on the second data packet at the SDAP layer or the PDCP layer;

[0749] The size of the first data packet exceeds the maximum data packet limit of the PDCP, and / or the size of the second data packet does not exceed the maximum data packet limit of the PDCP. Optionally, this method can be used for network energy conservation, services related to network energy conservation, or other services independent of network energy conservation. This method is applicable to scenarios where high-layer data exceeds the low-layer data transmission limit, such as scenarios where the transmitted data exceeds the 9000 bytes required by the PDCP.

[0750] When this method is used in other transmission scenarios independent of network energy saving, such as Extended-Range (XR) services, the data packet size is relatively large and the data packet size is variable. For example,

[0751] 30 Mbps: Average packet size: 0.5 Mbit = 62,500 bytes. The minimum to maximum packet size is 0.5 to 1.5 times the average packet size.

[0752] 60 Mbps: Average packet size: 1 Mbit = 125,000 bytes. The minimum to maximum packet size is 0.5 to 1.5 times the average packet size.

[0753] However, the current Packet Data Convergence Protocol (PDCP) Service Data Unit (SDU) has a data packet size limit of no more than 9000 bytes. The maximum supported size of a PDCP SDU is 9000 bytes. The maximum supported size of a PDCP Control PDU is 9000 bytes.

[0754] Therefore, it is possible that the size of an XR packet exceeds the PDCP packet size limit. To solve this problem, the following functions can be introduced for the transmitter and / or receiver (the transmitter includes the terminal and / or base station, and the receiver includes the terminal and / or base station):

[0755] Transmitter: Add a segmentation function. Optionally, the function is implemented in the Service Data Adaptation Protocol (SDAP) (for example, after identifying the PDU set or before routing), or in the PDCP.

[0756] · Receiving end: Add a re-assembly function. Optionally, the function is implemented in SDAP or PDCP.

[0757] For example, for PDCP implementation, the architecture may be as shown in FIG. 24 .

[0758] In addition, the network configuration may configure the service cycle to be non-divisible by 10240ms, the DRX cycle to be non-divisible by 10240ms, the CG / SPS cycle to be non-divisible by 10240ms, the DRX pattern to be non-divisible by 10240ms, or the CG / SPS pattern to be non-divisible by 10240ms. This situation may occur in a network energy-saving environment or may be independent of network energy saving, that is, it is not coupled with network energy saving.

[0759] 1. When the above calculation method is used for other services independent of network energy saving, if the service period is not divisible by 10240ms, or the DRX period is not divisible by 10240ms, or the CG / SPS period is not divisible by 10240ms, or the periodic DRX pattern is not divisible by 10240ms, or the periodic CG / SPS pattern is not divisible by 10240ms, then when the SFN wraps around, the PUSCH / PDSCH / DRX position calculated based on the position of the SFN start (SNF0) after the wrap around is problematic.

[0760] For example, XR traffic suffers from a periodicity mismatch: for 60 FPS video traffic, the traffic period is 1000 / 60 = 50 / 3 (ms), meaning the traffic pattern repeats every 50 ms. However, SFN runs from 0 to 1024, and 10240 ms is not an integer multiple of 50 ms.

[0761] There is a periodicity mismatch issue for XR traffic: For a video traffic of 60FPS, the traffic periodicity is 1000 / 60=50 / 3(ms), which means the traffic pattern repeats in every 50ms. However, the SFN runs from 0 to 1024, and 10240ms is not an integer multiple of 50ms.

[0762] Therefore, in this case, we need to solve the problem of not being divisible by 10240ms. There are three main cases:

[0763] Case 1: The DRX cycle cannot be divided evenly by 10240ms, and the existing DRX start calculation formula (Long and Short DRX cycle starts) is modified. The position of the SFN or subframe or slot on the left side of the equal sign is the accumulated SFN or subframe or slot. Specifically, the accumulated SFN or subframe or slot is the accumulated SFN or subframe or slot from the DRX start position (after receiving the DRX configuration, the position of the first DRX after receiving the DRX configuration, or the position of the first calculated DRX cycle, or the first position calculated for the DRX configuration) to the current SFN or subframe or slot. If the accumulated SFN or subframe or slot satisfies the equation, the SFN or subframe or slot is the calculated starting position of this DRX cycle.

[0764] For example: (taking subframe as an example, or ms as an example)

[0765] 1. If the short DRX cycle is used for one DRX group, and [A] modulo (drx-ShortCycle) = (drx-StartOffset) modulo (drx-ShortCycle).

[0766] If the Short DRX cycle is used for a DRX group,and[A]modulo(drx-ShortCycle)=(drx-StartOffset)modulo(drx-ShortCycle).

[0767] Here, A=(SFN×10)+subframe number, where A is the accumulated subframe, or SFN is the accumulated SFN.

[0768] 2. After drx-SlotOffset at the start of the subframe, start the drx-on duration timer for this DRX group.

[0769] Start drx-on duration timer for this DRX group after drx-SlotOffset from the beginning of the subframe.

[0770] Another example:

[0771] 1. If the long DRX cycle is used for one DRX group, and [B] modulo (drx-ShortCycle) = (drx-StartOffset) modulo (drx-ShortCycle).

[0772] If the Long DRX cycle is used for a DRX group,and[B]modulo(drx-LongCycle)=drx-StartOffset.

[0773] Wherein B=(SFN×10)+subframe number, B is the accumulated subframe, or SFN is the accumulated SFN.

[0774] 2. Alternatively:

[0775] 3. After drx-SlotOffset at the start of the subframe, start the drx-on duration timer for this DRX group.

[0776] Start drx-onDurationTimer for this DRX group after drx-SlotOffset from the beginning of the subframe.

[0777] Another example:

[0778] 1. If the short DRX cycle is used for one DRX group, and [A] modulo (drx-ShortCycle-slot-level) = (drx-StartOffset) modulo (drx-ShortCycle).

[0779] If the Short DRX cycle is used for a DRX group,and[A]modulo(drx-ShortCycle-slot-level)=(drx-StartOffset)modulo(drx-ShortCycle-slot-level). Among them, A=(SFN×10)+subframe number+slot.

[0780] Where A is the accumulated slot.

[0781] 2. After the subframe starts, start the drx-on duration timer for this DRX group.

[0782] Start drx-on duration timer for this DRX group from the beginning of the subframe.

[0783] Case 2: The periodic DRX pattern cannot be divided evenly by 10240ms. When calculating the position of each pattern of the periodic DRX pattern, or the starting position, the position used in the formula is the accumulated SFN or subframe or time slot. Specifically, the accumulated SFN or subframe or time slot is the accumulated SFN or subframe or time slot from the DRX start position (after receiving the DRX configuration, the position of the first DRX after receiving the DRX configuration, or the position of the first DRX cycle calculated, or the first position calculated for the DRX configuration) to the current SFN or subframe or time slot. If the accumulated SFN or subframe or time slot satisfies the equation, the SFN or subframe or time slot is the calculated starting position of this DRX cycle.

[0784] For example, the position of the Nth pattern is: [pattern start position + N * pattern period] modulo (10240 ms) = (pattern-StartOffset). The pattern start position is at the timeslot or subframe level. Optionally, the first DRX drx-on duration timer is enabled in this timeslot of the pattern.

[0785] For example, the position of the Nth pattern is: [pattern start position + N * pattern period] modulo (10240 ms) = (pattern-StartOffset). The pattern start position is at the subframe level. Optionally, the first DRX drx-on duration timer is enabled after the timeslot offset at the start of this subframe.

[0786] Case 3: The periodic CG / SPS pattern cannot be divided evenly by 10240ms. When calculating the position of each pattern of the periodic CG / SPS pattern, or the starting position, the position used in the formula is the accumulated SFN or subframe or time slot. Specifically, the accumulated SFN or subframe or time slot is the accumulated SFN or subframe or time slot from the DRX start position (after receiving the DRX configuration, the position of the first DRX after receiving the DRX configuration, or the position of the first DRX cycle calculated, or the first position calculated for the DRX configuration) to the current SFN or subframe or time slot. If the accumulated SFN or subframe or time slot satisfies the equation, the SFN or subframe or time slot is the calculated starting position of this DRX cycle.

[0787] For example, the position of the Nth pattern is: [pattern start position + N * pattern period] modulo (10240ms) = (pattern - StartOffset). The pattern start position is at the slot level or subframe level. Optionally, the slot position of the pattern is the CG / SPS opportunity position, or the slot position of the pattern + symbol offset is the CG / SPS opportunity position.

[0788] For example, the position of the Nth pattern is: [pattern start position + N*pattern period] modulo (10240ms) = (pattern - StartOffset). The pattern start position is at the symbol level. Optionally, the CG / SPS opportunity position starts at this symbol of the pattern.

[0789] In addition, in the network configuration, there may be multiple PUSCH / PDSCH opportunities in a CG / SPS period, or multiple CG / SPS (thus multiple PUSCH / PDSCH opportunities) may be used to transmit a service. This situation can occur in the context of network energy saving or independently of network energy saving. In other words, there is no coupling relationship with network energy saving.

[0790] 2. When a CG / SPS period has multiple PUSCH / PDSCH opportunities, or multiple CG / SPSs (which will also have multiple PUSCH / PDSCH opportunities) are used to transmit a service, the terminal or network can indicate whether some opportunities are used or canceled. Further, it can include at least one of the following:

[0791] Indicates whether some opportunities in the current cycle are used or cancelled, or indicates whether some opportunities in the subsequent cycle(s) are used or cancelled;

[0792] · Indicates the location or identity of the opportunity(s) being used or cancelled;

[0793] Indicated by one of MAC CE, RRC, CG-UCI, SR, UCI, DCI, and DL DG-DCI (DG carries indication information);

[0794] By indicating a specific opportunity in a cycle, such as the first, the first N (N can be 1), or the first X opportunities used or cancelled;

[0795] Partially used or cancelled opportunities may be, for example, the last one or the last Y opportunities.

[0796] Optionally, the above indication may be in the first or a specific one or several opportunities or CG / SPS index indications, or in the currently activated or used opportunity or CG / SPS index indications.

[0797] Furthermore, there may be situations where packet loss processing is required for remaining PDUs (e.g., PDUs in a PDU set that have not yet been transmitted, or PDUs that meet the PDU set delay budget but have not yet been transmitted or have been successfully transmitted) or PDU sets during transmission or data arrival, or where packet loss processing is indicated for the remaining PDUs or PDU sets, or where packet loss processing is supported for the remaining PDUs or PDU sets. This situation may occur in the context of network energy conservation or independently of network energy conservation. In other words, it is not coupled with network energy conservation.

[0798] 3. When packet loss processing is to be performed on the remaining PDUs (such as PDUs in a PDU set that have not been transmitted, or PDUs that meet the PDU set delay budget but have not been transmitted or have been successfully transmitted) or PDU sets, or when packet loss processing is instructed to be performed on the remaining PDUs or PDU sets, or when packet loss processing is supported for the remaining PDUs or PDU sets, the packet loss processing execution entity may be the sender and / or the receiver. Optional:

[0799] The transmitting end determines whether to perform packet loss processing based on the indication information of the receiving end. If indication information is received, or feedback (such as negative acknowledgment (NON-Acknowledge, NACK) (for a PDU set or a PDU of a PDU set)) is received, packet loss processing is performed. The indication information may be sent by the receiving end itself. For example, the receiving end may send the indication information to the transmitting end in one of the following situations: the receiving end performs packet loss processing when at least one of the following conditions is met: the status report trigger is satisfied, or the PSDB times out, or there is a PDU set transmission failure (such as NACK), or there is a PDU transmission failure (such as NACK) in the PDU set; or the transmitting end sends the indication information after requesting it, such as when the receiving end receives a request for feedback and / or a request for a status report. The indication information may be a packet loss indication, or a status report, or a PSDB timeout.

[0800] The receiving end determines whether to perform packet loss processing based on the indication information from the sending end. If indication information is received; or, a packet loss indication is received; or, PSDB times out; or, a PDU sending status indication is received, such as partial data is not sent or successfully sent (for a PDU set or a PDU of a PDU set), packet loss processing is performed. The indication information can be sent by the sending end itself (such as if the status report is met, or PSDB times out, or the transmission status of the PDU or PDU set needs to be confirmed, the sending end performs packet loss processing), or it can be requested by the receiving end (such as requesting the sending end to send the indication information).

[0801] The receiving end determines whether to perform packet loss processing based on the transmission status of the PDU aggregate or PDU aggregate packet. For example, packet loss processing is performed when the PSDB is exceeded, a packet is determined to be untransmitted, a packet is transmitted, or a NACK feedback is received.

[0802] The sender determines whether to perform packet loss processing based on the transmission status of the PDU aggregate or PDU aggregate packet. For example, packet loss processing is performed when the PSDB is exceeded, a packet is determined to be untransmitted, a packet is transmitted, or a NACK feedback is received.

[0803] In addition, whether SR (PUCCH) and PUSCH in different PUCCH groups can be transmitted simultaneously, or whether this is considered an overlap issue, one of the following solutions can be considered. This issue can occur in the context of network energy saving or can be independent of network energy saving, that is, it is not coupled with network energy saving.

[0804] Option 1: Overlap determination or simultaneous transmission is limited to the same PUCCH group. For example, only when SR and PUSCH within a PUCCH group collide is it considered a conflict, or only when it affects prioritization, or only when it affects the decision of whether to prioritize resources. Alternatively, it is considered that SR (PUCCH) and PUSCH in the same PUCCH group cannot be transmitted simultaneously. Alternatively, it is considered that SR (PUCCH) and PUSCH in different PUCCH groups can be transmitted simultaneously.

[0805] The protocol that may be affected is TS 38.321. The following is an example of a protocol impact:

[0806] When the MAC entity is configured with lch-basedPrioritization,for each uplink grant delivered to the HARQ entity and whose associated PUSCH can be transmitted by lower layers,the MAC entity shall:

[0807] 1>if this uplink grant is received in a Random Access Response(i.e.in a MAC RAR or fallback RAR),or addressed to Temporary C-RNTI,or is determined as specified in clause 5.1.2a for the transmission of the MSGA payload:

[0808] 2>consider this uplink grant as a prioritized uplink grant.

[0809] 1>else if this uplink grant is addressed to CS-RNTI with NDI=1 or C-RNTI:

[0810] 2>if there is no overlapping PUSCH duration of a configured uplink grant which was not already de-prioritized,in the same BWP,whose priority is higher than the priority of the uplink grant;and

[0811] 2>if there is no overlapping PUCCH resource with an SR transmission which was not already de-prioritized,in the same PUCCH group,and the simultaneous transmission of the SR and the uplink grant is not allowed by configuration of simultaneousPUCCH-PUSCH or simultaneousPUCCH-PUSCH-SecondaryPUCCHgroup,and the priority of the logical channel that triggered the SR is higher than the priority of the uplink grant:

[0812] 3>consider this uplink grant as a prioritized uplink grant;

[0813] 3>consider the other overlapping uplink grant(s),if any,as a de-prioritized uplink grant(s);

[0814] 3>consider the other overlapping SR transmission(s),if any,as a de-prioritized SR transmission(s);

[0957] Example 4 (a method of BWP switch):

[0958] Note: The method of this embodiment can also be applied to Pcell switching and Scell ​​reactivation.

[0959] The specific implementation process is as follows:

[0960] 1. The network explicitly or implicitly instructs the UE to perform BWP switching through the first information. Specifically, it may include at least one of the following:

[0961] a) The instructing the UE to perform BWP switching may also be instructing the UE to switch from the first BWP to the second BWP.

[0962] b) The BWP after switching, or the second BWP, is a default BWP, or a previous BWP (such as: the BWP before switching to the first BWP, such as the BWP before the BWP switching indication, such as the BWP used when or under what circumstances the first information and / or the second information is received), or a specific BWP (such as at least one of the following: a network energy-saving BWP, a non-energy-saving BWP, a BWP with a specific identifier such as a BWP index, an initial BWP), or a BWP indicated in the first information, or a BWP indicated by the second information (such as the first information carried in group information (such as group RNTI, group DCI, group MAC CE), and the second information carried in the SIB, or the first information carried in the SIB, and the second information carried in the group information (such as group RNTI, group DCI, group MAC CE)).

[0963] c) The first information may include at least one of the following:

[0964] i.BWP switching indication;

[0965] ii. Network status indication or network status change;

[0966] iii. The BWP logo after switching;

[0967] iv. Network load;

[0968] v. Whether to prioritize network energy saving or transmission performance.

[0969] d) The first information is received through a common search space, or through a UE-specific search space, or through a specific search space (network configured or predefined). In addition, optionally, the common search space and / or UE-specific search space can be shared or independently configured.

[0970] i. For example, all are received through a common search space.

[0971] ii. For example, all are received through the terminal-specific search space.

[0972] iii. For example, all are received through a specific search space.

[0973] iv. For example, when the network load is low or no load, or the network state is the first state (such as no load, low load, base station or cell DRX, base station or cell DTX, energy saving state, etc.), or when the UE obtains that the network load is low or no load, or when the UE obtains that the network state is the first state (such as no load, low load, base station or cell DRX, base station or cell DTX, energy saving state, etc.), it is received through the public search space, or it is received through the specific search space.

[0974] v. For example, when the network load is high, or the network state is in the second state (such as high load, non-energy-saving state, etc.), or in the case of normal transmission, or when the UE obtains that the network load is high, or the UE obtains that the network state is in the second state (such as high load, non-energy-saving state, etc.), or the UE obtains normal transmission, it is received through the terminal-specific search space, or received through the specific search space.

[0975] vi. For example, the UE switches off to the BWP to be switched according to the BWP information indicated by the network in the first information and / or the second information (such as the BWP index to be switched to indicated by the network).

[0976] vii. For example, when the network load is low or no load, or the network state is the first state (such as no load, low load, base station or cell DRX, base station or cell DTX, energy saving state, etc.), or when the UE obtains that the network load is low or no load, or the UE obtains that the network state is the first state (such as no load, low load, base station or cell DRX, base station or cell DTX, energy saving state, etc.), or the UE is instructed to perform BWP switching (if there is a BWP switching indication bit (bit), a BWP index may or may not be given), the UE switches to BWP A. The BWP A can be at least one of the following: a default BWP (such as the default BWP 1. Predefined, or the network as indicated through SIB), a specific BWP (such as at least one of the following: a network energy-saving BWP, a BWP with a specific identifier such as a BWP index (such as the one with the smallest index, such as index 0), an initial BWP), a small bandwidth BWP, a previous BWP (such as the first BWP, or, such as the BWP used when the BWP switching indication or the first information indication is received, or, such as the BWP used before the currently used or activated BWP), a large bandwidth BWP.

[0977] For example, if the network instructs each UE which BWP to switch to, there will be issues with handover latency and network overhead. This problem can be solved by allowing the UE to autonomously switch to the original BWP.

[0978] ·For example: if the gNB knows the no / small traffic load, the gNB could switch all or most UEs to the same bandwidth part with a small bandwidth.Such BWP switch can be indicated to the UE via one group common DCI.

[0979] a) UE can switch to the BWP indicated by network, or, UE can autonomously switch to the initial BWP, or, the index M BWP, or, the BWP defined for energy saving.

[0980] viii. For example, when the network load is high, or the network state is in the second state (such as high load, or non-energy-saving state, etc.), or in the case of normal transmission, or when the UE obtains that the network load is high, or the UE obtains that the network state is in the second state (such as high load, non-energy-saving state, etc.), or the UE obtains normal transmission, or the UE is instructed to perform BWP switching (if there is a BWP switching indication bit, a BWP index may or may not be given), the UE switches to BWP B. The BWP B may be at least one of the following: a default BWP (such as a default BWP 2, predefined, or indicated by the network through an SIB), a specific BWP (such as at least one of the following: a non-network energy-saving BWP, a non-specific identifier such as a BWP indexed by a BWP (such as an index other than 0 or the minimum), a specific identifier such as a BWP indexed by a BWP (such as the largest index), a non-initial BWP), a previous BWP (such as: a BWP before switching to the first BWP, or, such as the first BWP, or, such as the BWP used when a BWP switching indication or a first information indication is received, or, such as the BWP used before the currently used or activated BWP), a large bandwidth BWP.

[0981] For example, if the network instructs each UE which BWP to switch to, there will be issues with handover latency and network overhead. This problem can be solved by allowing the UE to autonomously switch to the original BWP.

[0982] ·For example: if the network traffic load changes to larger, the activated BWP for each UE can be adapted accordingly. For example, the UE can autonomous switch to the previous BWP (when the BWP switch indication is received) or the UE switches to the BWP with large bandwidth which is explicitly indicated by the network.

[0983] e) The UE is a UE accessing the current cell, or a UE camping in the current cell, or a UE configured / instructed to a specific group, or a UE with network energy saving capability, or a UE that has reported network energy saving capability or demand.

[0984] f) The first information may further include at least one of the following: a switching time or a switching delay offset.

[0985] g) Optionally, the first information may be carried by a SIB or in the first information. The first information may be group DCI or group RNTI scrambled DCI, or group DCI or group RNTI scrambled DCI scheduled PDSCH (e.g., RAR).

[0986] √For example: A MAC PDU carries one or more MAC sub-PDUs, and each MAC sub-PDU corresponds to a UE-specific information.

[0987] √For example, a MAC PDU carries one or more MAC sub-PDUs, and each MAC sub-PDU corresponds to the information of a UE group.

[0988] √For example, a MAC PDU carries one or more MAC sub-PDUs, and each MAC sub-PDU corresponds to a cell-level information.

[0989] 2. The UE performs BWP switching. There are two options:

[0990] a) Solution 1: When the terminal receives the first information, it performs BWP switching;

[0991] b) Solution 2: When the terminal receives the first information, it performs BWP switching at the indicated switching time, or at the time of receiving / decoding the first information + the offset time.

[0992] Beneficial Effects: A BWP switch method is introduced to address different network loads. Alternatively, a unified or specific BWP switch method is provided to address network energy conservation. This embodiment can be used alone or in combination with other embodiments in this solution, such as Embodiment 1.

[0993] Example 5 (method for using DRX, or method for changing or using DRX parameters):

[0994] The specific implementation process is as follows (applicable to UL and / or DL):

[0995] 1. The network configures DRX parameters or configurations.

[0996] a) The DRX parameters or configurations are for the UE (not for the cell).

[0997] 2. The UE receives the DRX parameters or configuration configured by the network and performs DRX transmission or reception.

[0998] 3. The UE executes the updated DRX parameters or configuration according to the network indication information, or transmits according to the updated DRX parameters or configuration. Specifically, it may include at least one of the following:

[0999] a) The DRX parameters or configurations may be all or part of existing DRX parameters, or all or part of DRX parameters newly added in subsequent versions.

[1000] b) For example, the network configures multiple sets of DRX parameters or configurations corresponding to different indices. The UE performs data transmission according to the DRX parameter or configuration index indicated by the network and the value corresponding to the index indicated by the network.

[1001] i. In particular, the multiple sets of DRX parameters or configurations are two sets, and the UE directly switches between the two sets (for example, as long as it receives a DRX parameter or configuration switching indication, or receives an update indication of the network status or network load or whether energy saving is performed, it can switch between the two sets).

[1002] ii. For example, in energy-saving situations, DRX parameters or configurations with a short on-duration or a long cycle are used. For example, in non-energy-saving situations, DRX parameters or configurations with a long on-duration or a short cycle are used.

[1003] c) For example, the network configures multiple sets of DRX parameters or configurations, with different configurations corresponding to different network states, network loads, or energy-saving requirements. The UE determines the DRX parameters or configuration to use and performs data transmission based on the network state, network load, or energy-saving requirements indicated by the network.

[1004] d) For example, the network configures a set of DRX parameters or configurations corresponding to a network state (e.g., low load, energy saving, cell DRX / DTX, etc.) or a network load (e.g., low, no, etc.) or an energy saving requirement. The UE determines whether to use the DRX parameters or configurations based on the network state or load or energy saving requirement indicated by the network and performs data transmission.

[1005] e) For example, the network indicates the update of DRX parameters or configuration at the cell or UE group level through common DCI or common MAC CE or system information or PDSCH content carried by common DCI. The UE uses the updated configuration and performs transmission according to the update.

[1006] Beneficial Effect: This invention introduces a method for using or updating DRX parameters based on energy-saving requirements or network status. This method achieves network energy conservation while also reducing complexity and latency. This embodiment can be used alone or in combination with other embodiments in this solution, such as Embodiment 1.

[1007] Example 6 (UE group or cell-level handover implementation method):

[1008] The specific implementation process is as follows:

[1009] 1. The base station switches the UE(s) to the second cell through group handover or cell-level handover. Specifically, this may include at least one of the following:

[1010] a) For example, when the current serving cell is turned off, or when energy saving is required, or when the network has low or no load, the UE is handed over to the second cell.

[1011] b) The parameters or configurations for group handover or cell-level handover include a common part and / or a UE-specific part.

[1012] i. The common part is carried in the SIB. Alternatively, the common part is carried in the first information, and the terminal-specific part is carried in the second information. Alternatively, it is carried in the first information together with the terminal-specific part. The first information may be a DCI scrambled by the group DCI or the group RNTI, or a PDSCH scheduled by the DCI scrambled by the group DCI or the group RNTI (for example, in the RAR manner). The second information is a PDSCH scheduled by the DCI scrambled by the group DCI or the group RNTI (for example, in the RAR manner).

[1013] For example, a MAC PDU carries one or more MAC sub-PDUs, each of which corresponds to terminal-specific information. Optionally, a MAC PDU can also carry one or more MAC sub-PDUs that carry public information.

[1014] ◆Optionally, the terminal-specific information may be for each UE or for UEs at a certain location (such as different locations, different coordinate intervals).

[1015] ◆Optional, public information can be for all UEs in the cell, for UEs in a certain location, or for UEs in a certain group.

[1016] a) For example, public is for a cell, and terminal-specific is for a UE at a certain location.

[1017] b) For example, public is for a UE group, and terminal-specific is for a certain UE.

[1018] c) For example, public is for a cell, and terminal-specific is for a certain UE group.

[1019] 2. The UE performs handover according to the handover information.
