Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a data transmission method, apparatus, network-side equipment, and terminal. Background Technology

[0002] When a user configures a Discontinuous Reception (DRX) group, the User Equipment (UE) will discontinuously monitor the Physical Downlink Control Channel (PDCCH) of all serving cells. During the DRX period, the UE only monitors the PDCCH during the active period. During the "Opportunity for DRX" or the inactive period (DRX off), the UE does not receive any PDCCH except for scheduling broadcast signaling in order to reduce power consumption; that is, it enters sleep mode.

[0003] The DRX mechanism primarily prevents PDCCHs scrambled with the following Radio Network Temporary Identity (RNTI) during inactive periods from being monitored: Cell Radio Network Temporary Identity (C-RNTI), Control Information Radio Network Temporary Identity (CI-RNTI), Configured Scheduling Radio Network Temporary Identity (CS-RNTI), Interruption Radio Network Temporary Identity (INT-RNTI), Slot Format Indication Radio Network Temporary Identity (SFI-RNTI), Semi Persistent Channel State Information Radio Network Temporary Identity (SP-CSI-RNTI), Transmit Power Control Physical Uplink Control Channel Radio Network Temporary Identity (TPC-PUCCH-RNTI), and Transmit Power Control Physical Uplink Shared Channel Radio Network Temporary Identity. The three RNTIs are: C-RNTI (TPC-PUSCH-RNTI), Transmit Power Control-Sounding Reference (TPC-SRS-RNTI), and AI-RNTI. C-RNTI is primarily used for DCI scrambling in data scheduling.

[0004] It is evident that the existing DRX mechanism is affected by the DRX activation period parameter configuration for scheduling-related RNTI. Therefore, the DRX parameter configuration needs to consider the combined impact of multiple services, making it difficult to match the DRX period configuration with specific services. This will introduce unnecessary waiting transmission delays. Summary of the Invention

[0165] In the embodiments of this application, the term "and / or" describes the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. The character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0166] In the embodiments of this application, the term "multiple" refers to two or more, and other quantifiers are similar.

[0167] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0168] The technical solutions provided in this application can be applied to various systems, especially 5G systems. For example, applicable systems include Global System for Mobile Communication (GSM), Code Division Multiple Access (CDMA), Broadband Code Division Multiple Access (8CDMA) General Packet Radio Service (GPRS), Long Term Evolution (LTE), LTE Frequency Division Duplex (FDD), LTE Time Division Duplex (TDD), Long Term Evolution Advanced (LTE-A), Universal Mobile Telecommunication System (UMTS), Worldwide Interoperability for Microwave Access (8iMAX), and 5G New Radio (NR), etc. All of these systems include terminal equipment and network-side equipment. The system may also include a core network component, such as the Evolved Packet System (EPS) or the 5G system (5GS).

[0169] The terminal involved in the embodiments of this application can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The name of the terminal may differ in different systems; for example, in a 5G system, the terminal can be called a User Equipment (UE). Wireless terminal devices can communicate with one or more core networks (CNs) via a Radio Access Network (RAN). Wireless terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, for example, portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (LL) stations, and Personal Digital Assistants (PDAs). Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, access point, remote terminal, access terminal, user terminal, user agent, or user device, but is not limited to these terms in the embodiments of this application.

[0170] Figure 1 This diagram illustrates a block diagram of a wireless communication system applicable to embodiments of this application. The wireless communication system includes a terminal device 11 and a network-side device 12. The terminal device 11 can also be referred to as a terminal or a user equipment (UE). It should be noted that this application does not limit the specific type of the terminal 11. The network-side device 12 can be a base station or a core network. It should be noted that this application uses a base station in an NR system as an example, but does not limit the specific type of base station.

[0171] The data transmission method, apparatus, network-side device, and terminal provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0172] like Figure 2 The diagram shown is a flowchart illustrating one of the steps of an output transmission method according to an embodiment of this application. The method includes:

[0173] Step 201, the network-side device generates a first downlink control information (DCI); the first DCI includes: scheduling information for the first service;

[0174] Step 202: The network-side device transmits the first DCI during the discontinuous reception DRX activation period and / or DRX inactivation period.

[0175] In the data transmission method of this application embodiment, the network-side device generates a first DCI including scheduling information of a first service, and sends the first DCI to the terminal during the DRX activation period and / or deactivation period. This ensures that the first DCI carries only the scheduling information of the first service, enabling the network-side device to configure dedicated data transmission information for the terminal. Sending the first DCI to the terminal during the DRX activation period and / or deactivation period allows the terminal to listen for the first DCI during discontinuous reception of the DRX activation period and / or DRX deactivation period. Thus, the terminal can perform dynamic data scheduling DCI listening based on service characteristics without being restricted by the DRX mechanism, thereby solving the problem that the current DRX parameter configuration requires consideration of the combined effects of multiple services, making it difficult to match the DRX cycle configuration with specific services and introducing unnecessary waiting transmission delays. Simultaneously, it also ensures discontinuous reception of other services.

[0176] As an optional implementation, the first DCI uses a dedicated identifier related to the first service for scrambling.

[0177] In this optional implementation, the dedicated identifier related to the first service can be a service-specific RNTI, such as X-RNTI, used for service transmission detection. The DCI monitoring scrambled with this service identifier RNTI is not controlled by DRX; that is, the terminal can still monitor the first DCI even during DRX inactivity. This allows network-side devices to configure dedicated data transmission information for the terminal, and the terminal can dynamically schedule DCI monitoring based on service characteristics without DRX restrictions, avoiding unnecessary transmission delays introduced by the difficulty of matching DRX periodic configuration with specific services.

[0178] Furthermore, as an optional implementation, the method also includes:

[0179] The network-side device configures a first search space set during the DRX activation period and / or a second search space set during the DRX inactivation period for the first DCI.

[0180] The first search space set and the second search space set may be the same or different.

[0181] It should be noted that, based on the network-side device configuring a first search space set during the DRX activation period and / or a second search space set during the DRX inactivation period for the first DCI, the terminal may only use the first search space set to listen to the first DCI during the DRX activation period, or the terminal may only use the second search space set to listen to the first DCI during the DRX inactivation period, or the terminal may use the first search space set configured by the network-side device to listen to the first DCI during the DRX activation period and the second search space set configured by the network-side device to listen to the first DCI during the DRX inactivation period.

[0182] It should also be noted that when the network-side device configures a first search space set and a second search space set for the first DCI, the terminal can use the same or different search space sets to monitor the first DCI during the DRX activation period and the DRX inactivation period. The search space set parameters may include, but are not limited to, the monitoring period, the Bandwidth Part (BWP), the Aggregation Level (AL), the number of days for transmission / reception, the number of transmission / reception layers, and the maximum layer data for transmission / reception. A specific example of the network-side device configuring multiple search space sets for the first DCI is as follows:

[0183] Example 1: The network-side device configures multiple sets of search space set parameters for the X-RNTI scrambled DCI (first DCI). For example, the network-side device configures search space set 1 and search space set 2 for the DRX active period and the DRX inactive period, respectively. In this way, during the DRX active period, the terminal uses search space set 1 to listen to the X-RNTI scrambled DCI (first DCI), and during the DRX inactive period, the terminal uses search space set 2 to listen to the X-RNTI scrambled DCI (first DCI).

[0184] Example 2: The network-side device can configure a set of search space parameters for the X-RNTI scrambled DCI (first DCI), and configure multiple sets of parameters within this search space set. Here, taking the listening period as an example, the search space set of the X-RNTI scrambled DCI (first DCI) is configured with listening period 1 and listening period 2, corresponding to the active and inactive periods of DRX, respectively. Listening period 1 is shorter than listening period 2, thus allowing for sparser listening behavior to be configured during the inactive period of DRX.

[0185] It should also be noted that the configuration method for the first DCI can be the same as the existing DCI search space set configuration method, or, from the perspective of terminal energy saving, the above-mentioned configuration method of configuring at least one search space set for the first DCI using the network-side device. The existing DCI search space set configuration method is as follows:

[0186] Network-side equipment allocates one or more search spaces to users via system messages. The configuration of each search space is periodic, and the terminal performs DCI detection within the configured search space. The time when the terminal performs DCI detection is called a DCI monitoring occasion. Search spaces are generally configured periodically. In a 5G NR system, to obtain downlink scheduling information, the terminal needs to monitor the DCI at each DCI monitoring occasion to determine if downlink scheduling information is present. Each DCI monitoring process is a DCI decoding process, and the result is then used to determine if the DCI carries UE scheduling information. If the DCI contains the terminal's scheduling information, the UE can obtain a positive CRC check and the scheduling information carried in the DCI; otherwise, the CRC check is negative, and the UE cannot obtain any information from the DCI.

[0187] The DCI parameter configuration is as follows:

[0188] The index of the search space set, i.e.: Search Space ID;

[0189] The control resource set ID, i.e., the CORESET ID, is used to establish the relationship between the search space s and the control resource set p.

[0190] DCI monitoring period k p，s and offset value o p，s The unit for each parameter is a time slot, and the terminal determines the time slot to listen to the DCI based on this configuration parameter.

[0191] DCI monitoring pattern within the slot;

[0192] Number of DCI candidates included in each aggregation level within the search space Supported aggregation levels include {1 2 4 8 16}, which can be configured via independent parameters;

[0193] The searchspace type is a flag used to distinguish whether the current search space is a public search space or a terminal-specific search space.

[0194] In this optional implementation, the network-side device configures at least one search space set for the first DCI, enabling the terminal to listen to the first DCI using the configured search space set during DRX activation or DRX inactivation periods. Alternatively, it can listen to the first DCI using the same or different search space sets during DRX activation and DRX inactivation periods. This achieves dynamic data scheduling of DCI listening based on service characteristics without being restricted by DRX under the DRX mechanism, avoiding unnecessary waiting delays and not affecting the transmission of other services.

[0195] Furthermore, as an optional implementation, the method also includes:

[0196] The network-side device sends a first indication message to the terminal, the first indication message being used to indicate at least one of the following:

[0197] The terminal performs listening skip and / or sleeps during the DRX activation period;

[0198] The terminal performs listening skip and / or sleep during DRX inactivity periods.

[0199] It should be noted that the first indication information can be carried within the first DCI, or it can be carried through other signaling that is receivable during the inactive period, such as Layer 1 signaling, energy-saving signals, MAC layer signaling, and higher-layer signaling. When the first indication information is carried within signaling other than the first DCI, there is no absolute order in which the network-side device sends the first indication information and the first DCI. The first DCI and the first indication information can be sent simultaneously, before the first DCI, or after the first DCI.

[0200] It should be noted that the first indication information is terminal power saving indication information. During the DRX activation period, the network-side device can use the first indication information to instruct the terminal to perform subsequent listening skip and / or sleep. Alternatively, during the DRX inactive period, the network-side device can use at least one signaling, including the first DCI, layer 1 signaling, power saving signal, MAC layer signaling, and higher layer signaling, to instruct the terminal to perform discontinuous first DCI listening behavior, thereby saving a certain amount of power consumption and reducing the waiting latency of the first service.

[0201] Here, it should also be noted that when the first indication information instructs the terminal to skip listening and / or sleep during the DRX activation period, the content indicated by the first indication information may specifically be at least one of the following: the terminal skips listening and / or sleeps during listening opportunities within the current listening window or during the DRX inactive period; that is: the terminal skips listening and / or sleeps during the remaining listening opportunities within the current listening window; the terminal skips listening and / or sleeps during the remaining listening positions configured within the current DRX activation period. When the first indication information instructs the terminal to skip listening and / or sleep during the DRX inactive period, the content indicated by the first indication information may specifically be at least one of the following: the terminal skips listening and / or sleeps during listening opportunities within the current listening window or during the DRX inactive period; that is: the terminal skips listening and / or sleeps during listening opportunities within the current listening window or during the DRX inactive period; the terminal skips listening and / or sleeps during the remaining listening opportunities within the current listening window; the terminal skips listening and / or sleeps during the remaining listening positions configured within the current DRX inactive period.

[0202] Furthermore, as an optional implementation, the method also includes:

[0203] The network-side device configures the listening location information of the first DCI; wherein the listening location information of the first DCI includes at least one of the following:

[0204] First listening position information of the first DCI during the DRX activation period;

[0205] Information on the second listening position of the first DCI during the DRX inactive period.

[0206] It should be noted here that the first listening location information and the second listening location information can be the same or different.

[0207] It should also be noted that the first DCI can be scrambled using C-RNTI, or scrambled using a dedicated identifier related to the first service. Specifically, during DRX activation, the terminal can monitor the first DCI based on the first monitoring location information and / or the first search space set configured by the network-side equipment; during DRX deactivation, the terminal can monitor the first DCI based on the second monitoring location information and / or the second search space set configured by the network-side equipment.

[0208] In this optional implementation, the monitoring location information of the first DCI is configured through the network-side equipment, enabling the terminal to monitor the first DCI according to the monitoring location information of the first DCI. In this way, the terminal can dynamically schedule DCI monitoring according to the service characteristics without being restricted by DRX under the DRX mechanism. This solves the problem that the current DRX parameter configuration needs to consider the comprehensive impact of multiple services, making it difficult to match the DRX period configuration with the specific service and introducing unnecessary waiting transmission delay. At the same time, it can also ensure the discontinuous reception of other services.

[0209] As an optional implementation, the network-side device configures the first DCI's listening location information, including at least one of the following:

[0210] The network-side device configures the monitoring location information semi-statically via higher-layer signaling.

[0211] The network-side device dynamically configures the monitoring location information using the first information.

[0212] In this optional implementation, the network-side device dynamically configures the monitoring location information through the first information, thereby dynamically adjusting the monitoring location of the first DCI. Specifically:

[0213] Network-side devices can configure the first service-specific listening location information during DRX inactivity periods. Simultaneously, the network-side devices configure first information for the terminal, indicating the duration for which the terminal will continue listening after detecting the service-specific DCI. This first information can be carried through Layer 1 signaling, MAC signaling, or higher-layer signaling. For example, the first information can be a listening timer or duration, an indication signaling message, or a reference signal. Taking a listening timer as an example, when the listening timer has not expired, the terminal can continue listening to the service-specific DCI (the first DCI). When service data packets are transmitted at the end of the listening window due to latency jitter, the data packets need to wait for the next listening window or opportunity to be transmitted because there are no subsequent listening opportunities. Configuring a listening timer helps reduce transmission latency caused by latency jitter.

[0214] Optionally, when the network-side device completes data transmission, it instructs the terminal to skip listening or go into sleep mode via the first indication information.

[0215] As a specific implementation method, the semi-static configuration of the listener location information includes:

[0216] The first DCI's listening window and / or listening start position information.

[0217] In other words, the semi-static configuration of the listening position information may include the listening window used to listen to the first DCI, and / or, the listening start position for listening to the first DCI.

[0218] As an optional implementation, the semi-statically configured listening location information includes at least one of the following:

[0219] Location information associated with the first line;

[0220] Independent listening location information.

[0221] It should be noted here that the first behavior can be periodic, semi-persistent, or non-periodic; among which, periodic or semi-persistent behavior includes at least one of the following:

[0222] Channel State Information (CSI) measurement;

[0223] Radio Resource Management (RRM) measurement;

[0224] Radio Link Failure (RLM);

[0225] The time slot in which the Semi-persistent Scheduling PhysiaclDownlink Shared Channel (SPS PDSCH) is located;

[0226] The time slot in which the Hybrid Automatic Repeat request Acknowledgement (HARQ-ACK) feedback of SPS PDSCH occurs;

[0227] The round-trip time (RTT) time of SPS PDSCH is the time during which the timer is enabled or expires.

[0228] Start / end position of the DRX cycle;

[0229] Start / end position of DRX activation period;

[0230] Reference signal; the reference signal includes at least one of the following:

[0231] Synchronization Signal and PBCH block (SSB);

[0232] Channel State Information Reference Signal (CSI-RS);

[0233] Tracking Reference Signal (TRS).

[0234] Non-periodic behaviors include at least one of the following:

[0235] Downlink signaling;

[0236] CSI measurement;

[0237] Reference signals, such as CSI-RS, TRS, etc.

[0238] Here, it should be noted that, firstly, semi-persistent behavior refers to periodic behavior over a period of time; secondly, the granularity of the reference time point for determining the monitoring location information of the first DCI can be a time slot, a symbol, or a millisecond.

[0239] It should also be noted that independent listening location information refers to listening location information obtained directly without relying on any other information.

[0240] The independent listening location information includes at least one of the following:

[0241] Listening period and first offset value;

[0242] The absolute start time of the listening window;

[0243] Listening duration;

[0244] Listening termination time;

[0245] The time interval between adjacent listening windows;

[0246] The number of listening windows;

[0247] The number of monitoring start positions.

[0248] Specifically, the independent listening location information of the first DCI during the DRX activation period includes at least one of the following:

[0249] Listening period and first offset value;

[0250] The absolute start time of the listening window;

[0251] The start / end time and second offset value of periodic or semi-persistent behavior;

[0252] Listening duration;

[0253] Listening termination time;

[0254] The time interval between adjacent listening windows;

[0255] The number of first listening windows;

[0256] The number of the first listening start positions.

[0257] Specifically, the independent listening location information of the first DCI during the DRX inactivity period includes at least one of the following:

[0258] Listening period and first offset value;

[0259] The absolute start time of the listening window;

[0260] The start / end time and second offset value of periodic or semi-persistent behavior;

[0261] Listening duration;

[0262] Listening termination time;

[0263] The time interval between adjacent listening windows;

[0264] The number of second listening windows;

[0265] The number of second listening start positions.

[0266] The following example illustrates how to configure the monitoring location information of the first DCI using specific examples:

[0267] Example 1: The listening start time can be configured based on the listening period and the first offset value offset1. For example, the start time can meet the following conditions: Where, n f Frame number The slot number under subcarrier μ, k is the number of time slots contained in the next subframe of subcarrier μ. s For the listening period, o s This is the first offset value. Based on this, if the listening duration is configured, one or more listening windows can be determined; alternatively, the time interval T between adjacent listening windows can be configured. offset And / or the starting position of the listener / the number of listener windows, to determine multiple listener windows.

[0268] Example 2: Configuring the absolute start time T of the listening window start and the listening termination time T final Alternatively, the listening duration can be used to determine a listening window; that is, the absolute start time T of the listening window can be used as the basis.start and the listening termination time T final Determine a listening window, or, based on the absolute start time T of the listening window. start The listening duration is used to determine a listening window; based on this, if a time interval T between adjacent listening windows is configured... offset And / or the number of listening windows can determine the number of listening windows.

[0269] Example 3: The listening window or listening start position can be set to the second offset value offset2 of the start / end position of the existing periodic or semi-persistent behavior as the listening start time. Based on this, if the listening duration is configured, one or more listening windows can be determined; alternatively, the time interval T between adjacent listening windows can be configured. offset And / or the number of listener start positions / listening windows, determining multiple listener windows. It should be noted that the second offset value can be an offset position after the start position of the periodic or semi-persistent behavior, or an offset position before the start position of the periodic or semi-persistent behavior, or an offset position after the end position of the periodic or semi-persistent behavior, or an offset position before the end position of the periodic or semi-persistent behavior.

[0270] Furthermore, as an optional implementation, the method also includes:

[0271] The network-side device sends a second instruction to the terminal, the second instruction being used for the first service instruction.

[0272] In other words, when the network-side device receives the first service indication information sent by the core network, or when the network-side device identifies the downlink data service indication as the first service, the network-side device can notify the terminal that the current service is the first service through the second indication information. That is, the second indication information is used to indicate that the data transmission scheduled by the first DCI is the data transmission of the first service, so that the terminal can listen to the first DCI according to the pre-configured listening location information. In this way, the terminal can perform corresponding dynamic data scheduling and DCI listening according to the service characteristics without being restricted by DRX under the DRX mechanism. This solves the problem that the current DRX parameter configuration needs to consider the comprehensive impact of multiple services, making it difficult to match the DRX period configuration with the specific service and introducing unnecessary waiting transmission delay. At the same time, it can also ensure the discontinuous reception of other services.

[0273] As an optional implementation, the dedicated identifier related to the first service includes at least one of the following:

[0274] A dedicated identifier corresponding to the business type of the first business;

[0275] A dedicated identifier corresponding to the first data stream of the first service.

[0276] In other words, in this optional implementation, the dedicated identifier related to the first service can be a dedicated identifier corresponding to the service type of the first service, that is, different service types correspond to different dedicated identifiers; the dedicated identifier of the first service can also be a dedicated identifier corresponding to different types of data streams of the same service, that is, different data streams correspond to different dedicated identifiers in the same service, for example, I-frames, P-frames and B-frames in video stream services correspond to different dedicated identifiers. When the core network can indicate different encoded data streams, the network-side device can use the transmission priority of different encoded data streams to configure exclusive data stream identifiers (dedicated identifiers corresponding to encoded frames), such as X-RNTI, etc.

[0277] Furthermore, as an optional implementation, the method also includes:

[0278] The network-side device sends a third indication message to the terminal, the third indication message being used to indicate whether the terminal is listening to the first DCI during the DRX activation period and / or the DRX inactivation period.

[0279] It should be noted here that the third indication information is the service-specific monitoring indication information. That is, the network-side device can use the third indication information to instruct the terminal whether to monitor the first DCI during the DRX activation period and / or DRX inactivation period. In other words, the network-side device can send the third indication information to the terminal based on the first service transmission status to notify the terminal whether to monitor the first DCI during the DRX activation period and / or DRX inactivation period. That is, when the network-side device has configured at least one search space set, monitoring window, and monitoring start position for the first DCI, the network-side device can also use the third indication information to instruct the terminal whether to use at least one of the configured search space set, monitoring window, and monitoring start position to monitor the first DCI based on the first service transmission status, so as to save some power consumption and reduce the waiting latency of the first service.

[0280] Specifically, as an optional implementation, the third indication information is carried by at least one of the following:

[0281] Layer 1 signaling;

[0282] Media Access Control Layer Control Unit (MAC CE);

[0283] High-level signaling.

[0284] When the first signaling is Layer 1 signaling, when the network-side device determines that the current service is the first service, the network-side device carries third indication information through the scheduled DCI signaling / unscheduled DCI signaling during the DRX activation period, instructing the terminal to listen for the first DCI during the DRX activation period and / or the DRX inactive period; alternatively, it can carry the third indication information through unscheduled DCI signaling during the DRX inactive period, instructing the terminal to listen for the first DCI during the DRX activation period and / or the DRX inactive period; or it can carry the third indication information through a power-saving signal during the DRX inactive period, instructing the terminal to listen for the first DCI during the DRX activation period and / or the DRX inactive period.

[0285] When the first signaling is MAC CE, the network-side device can carry third indication information through the MAC CE in the PDSCH during the DRX activation period to instruct the terminal to listen for the first DCI during the DRX activation period and / or the DRX inactive period; it can also carry third indication information through the SPS PDSCH during the DRX inactive period to instruct the terminal to listen for the first DCI during the DRX activation period and / or the DRX inactive period.

[0286] When the first signaling is a higher-level signaling, different values ​​can be used to instruct the terminal whether to listen for the first DCI during the DRX activation period and / or inactivation period; for example, when the value is 1, the terminal is instructed to listen for the first DCI during the DRX inactivation period, and when the value is 2 or the default value, the terminal is instructed not to listen for the first DCI during the DRX inactivation period.

[0287] In the data transmission method of this application embodiment, the network-side device generates a first DCI including scheduling information of a first service, and sends the first DCI to the terminal during the DRX activation period and / or deactivation period. This ensures that the first DCI carries only the scheduling information of the first service, enabling the network-side device to configure dedicated data transmission information for the terminal. Sending the first DCI to the terminal during the DRX activation period and / or deactivation period allows the terminal to listen for the first DCI during discontinuous reception of the DRX activation period and / or DRX deactivation period. Thus, the terminal can perform dynamic data scheduling DCI listening based on service characteristics without being restricted by the DRX mechanism, thereby solving the problem that the current DRX parameter configuration requires consideration of the combined effects of multiple services, making it difficult to match the DRX cycle configuration with specific services and introducing unnecessary waiting transmission delays. Simultaneously, it also ensures discontinuous reception of other services.

[0288] like Figure 3 The diagram shown is a second step flowchart of the data transmission method according to an embodiment of this application. The method includes:

[0289] Step 301: The terminal receives the first downlink control information (DCI) sent by the network-side device during the discontinuous reception of DRX activation period and / or DRX inactivation period; the first DCI includes: scheduling information of the first service;

[0290] Step 302: The terminal listens to the first DCI during the DRX activation period and / or DRX inactivation period.

[0291] The data transmission method of this application embodiment involves a terminal receiving a first DCI (Distributed Information Center) including scheduling information for a first service sent by a network-side device during discontinuous DRX activation and / or DRX inactivation periods. The terminal also listens to the first DCI during the DRX activation and / or DRX inactivation periods. This allows the terminal to perform dynamic data scheduling and DCI listening based on service characteristics without being restricted by DRX, thereby solving the problem that current DRX parameter configurations, which require consideration of the combined effects of multiple services, make it difficult to match DRX cycle configurations with specific services, thus introducing unnecessary waiting and transmission delays.

[0292] As an optional implementation, the first DCI uses a dedicated identifier related to the first service for scrambling.

[0293] In this optional implementation, the dedicated identifier related to the first service can be a service-specific RNTI, such as X-RNTI, used for service transmission detection. The DCI monitoring scrambled with this service identifier RNTI is not controlled by DRX; that is, the terminal can still monitor the first DCI even during DRX inactivity. This allows network-side devices to configure dedicated data transmission information for the terminal, and the terminal can dynamically schedule DCI monitoring based on service characteristics without DRX restrictions, avoiding unnecessary transmission delays introduced by the difficulty of matching DRX periodic configuration with specific services.

[0294] As an optional implementation, the terminal listens to the first DCI during the DRX activation period and / or DRX inactivation period, including:

[0295] During the DRX activation period, the terminal listens to the first DCI according to the first search space set configured by the network-side device; and / or,

[0296] During the DRX inactivity period, the terminal listens to the first DCI according to the second search space set configured by the network-side device.

[0297] The first search space set and the second search space set may be the same or different.

[0298] It should be noted that, based on the network-side device configuring a first search space set during the DRX activation period and / or a second search space set during the DRX inactivation period for the first DCI, the terminal may only use the first search space set to listen to the first DCI during the DRX activation period, or the terminal may only use the second search space set to listen to the first DCI during the DRX inactivation period, or the terminal may use the first search space set configured by the network-side device to listen to the first DCI during the DRX activation period and the second search space set configured by the network-side device to listen to the first DCI during the DRX inactivation period.

[0299] Alternatively, when the network-side device configures a first search space set and a second search space for the first DCI, the terminal can use the same or different search space sets to listen to the first DCI during the DRX activation period and the DRX inactive period. Listening to the first DCI with different search space sets can enable a sparser listening behavior to be configured during the DRX inactive period, thereby saving some power consumption.

[0300] Furthermore, as an optional implementation, the method also includes:

[0301] The terminal receives first indication information sent by the network-side device, the first indication information being used to indicate at least one of the following:

[0302] The terminal performs listening skip and / or sleeps during the DRX activation period;

[0303] The terminal performs listening skip and / or sleep during DRX inactivity periods.

[0304] It should be noted that the first indication information can be carried within the first DCI, or it can be carried through other signaling that is receivable during the inactive period, such as Layer 1 signaling, energy-saving signals, MAC layer signaling, and higher-layer signaling. When the first indication information is carried within signaling other than the first DCI, there is no absolute order in which the network-side device sends the first indication information and the first DCI. The first DCI and the first indication information can be sent simultaneously, before the first DCI, or after the first DCI.

[0305] It should be noted that the first indication information is terminal power saving indication information. During the DRX activation period, the network-side device can use the first indication information to instruct the terminal to perform subsequent listening skip and / or sleep. Alternatively, during the DRX inactive period, the network-side device can use at least one signaling, including the first DCI, layer 1 signaling, power saving signal, MAC layer signaling, and higher layer signaling, to instruct the terminal to perform discontinuous first DCI listening behavior, thereby saving a certain amount of power consumption and reducing the waiting latency of the first service.

[0306] Here, it should also be noted that when the first indication information instructs the terminal to skip listening and / or sleep during the DRX activation period, the content indicated by the first indication information may specifically be at least one of the following: the terminal skips listening and / or sleeps during listening opportunities within the current listening window or during the DRX inactive period; that is: the terminal skips listening and / or sleeps during the remaining listening opportunities within the current listening window; the terminal skips listening and / or sleeps during the remaining listening positions configured within the current DRX activation period. When the first indication information instructs the terminal to skip listening and / or sleep during the DRX inactive period, the content indicated by the first indication information may specifically be at least one of the following: the terminal skips listening and / or sleeps during listening opportunities within the current listening window or during the DRX inactive period; that is: the terminal skips listening and / or sleeps during listening opportunities within the current listening window or during the DRX inactive period; the terminal skips listening and / or sleeps during the remaining listening opportunities within the current listening window; the terminal skips listening and / or sleeps during the remaining listening positions configured within the current DRX inactive period.

[0307] In this optional implementation, by indicating the above content through the first indication information, the terminal can perform discontinuous first DCI listening behavior, thereby saving a certain amount of power consumption and reducing the waiting latency of the first service.

[0308] Furthermore, as an optional implementation, the method also includes:

[0309] The terminal listens to the first DCI based on the listening location information of the first DCI; wherein the listening location information of the first DCI includes at least one of the following:

[0310] First listening position information of the first DCI during the DRX activation period;

[0311] Information on the second listening position of the first DCI during the DRX inactive period.

[0312] It should also be noted that the first DCI can be scrambled using C-RNTI, or scrambled using a dedicated identifier related to the first service. Specifically, during DRX activation, the terminal can monitor the first DCI based on the first monitoring location information and / or the first search space set configured by the network-side equipment; during DRX deactivation, the terminal can monitor the first DCI based on the second monitoring location information and / or the second search space set configured by the network-side equipment.

[0313] In this optional implementation, the terminal listens to the first DCI according to the first listening position information during the DRX activation period, and / or listens to the first DCI according to the second listening position during the DRX inactive period. This allows the terminal to dynamically schedule DCI listening based on service characteristics without being restricted by DRX under the DRX mechanism. This solves the problem that the current DRX period configuration is difficult to match with specific services due to the need to consider the comprehensive impact of multiple services in the DRX parameter configuration, which introduces unnecessary waiting transmission delays. At the same time, it can also ensure the discontinuous reception of other services.

[0314] As an optional implementation, the first DCI's listening location information is pre-configured by the network-side device or pre-defined by the protocol.

[0315] Furthermore, as an optional implementation, the method also includes at least one of the following:

[0316] The terminal receives the listening location information semi-statically configured by the network-side device through higher-layer signaling;

[0317] The terminal receives the monitoring location information dynamically configured by the network-side device based on the first information.

[0318] Specifically, the semi-statically configured listening location information includes:

[0319] The first DCI's listening window and / or listening start position information.

[0320] Specifically, the semi-static configuration of the listening location information includes at least one of the following:

[0321] Location information associated with the first line;

[0322] Independent listening location information.

[0323] It should be noted here that the first behavior can be periodic, semi-persistent, or non-periodic; among which, periodic or semi-persistent behavior includes at least one of the following:

[0324] Channel State Information (CSI) measurement;

[0325] Radio Resource Management (RRM) measurement;

[0326] Radio Link Failure (RLM);

[0327] The time slot in which the Semi-persistent Scheduling PhysiaclDownlink Shared Channel (SPS PDSCH) is located;

[0328] The time slot in which the Hybrid Automatic Repeat request Acknowledgement (HARQ-ACK) feedback of SPS PDSCH occurs;

[0329] The round-trip time (RTT) time of SPS PDSCH is the time during which the timer is enabled or expires.

[0330] Start / end position of the DRX cycle;

[0331] Start / end position of DRX activation period;

[0332] Reference signal; the reference signal includes at least one of the following:

[0333] Synchronization Signal and PBCH block (SSB);

[0334] Channel State Information Reference Signal (CSI-RS);

[0335] Tracking Reference Signal (TRS).

[0336] Non-periodic behaviors include at least one of the following:

[0337] Downlink signaling;

[0338] CSI measurement;

[0339] Reference signals, such as CSI-RS, TRS, etc.

[0340] Here, it should be noted that, firstly, semi-persistent behavior refers to periodic behavior over a period of time; secondly, the granularity of the reference time point for determining the first DCI's monitoring location information can be a time slot, a symbol, or a millisecond.

[0341] It should also be noted that independent listening location information refers to listening location information obtained directly without relying on any other information.

[0342] The independent listening location information includes at least one of the following:

[0343] Listening period and first offset value;

[0344] The absolute start time of the listening window;

[0345] Listening duration;

[0346] Listening termination time;

[0347] The time interval between adjacent listening windows;

[0348] The number of listening windows;

[0349] The number of monitoring start positions.

[0350] Specifically, the independent listening location information of the first DCI during the DRX activation period includes at least one of the following:

[0351] Listening period and first offset value;

[0352] The absolute start time of the listening window;

[0353] The start / end time and second offset value of periodic or semi-persistent behavior;

[0354] Listening duration;

[0355] Listening termination time;

[0356] The time interval between adjacent listening windows;

[0357] The number of first listening windows;

[0358] The number of the first listening start positions.

[0359] Specifically, the independent listening location information of the first DCI during the DRX inactivity period includes at least one of the following:

[0360] Listening period and first offset value;

[0361] The absolute start time of the listening window;

[0362] The start / end time and second offset value of periodic or semi-persistent behavior;

[0363] Listening duration;

[0364] Listening termination time;

[0365] The time interval between adjacent listening windows;

[0366] The number of second listening windows;

[0367] The number of second listening start positions.

[0368] Furthermore, as an optional implementation, the method also includes:

[0369] The terminal receives a second indication information sent by the network-side device, the second indication information being used for a first service indication.

[0370] In this optional implementation, the terminal can determine the current service as the first service based on the second indication information, so that the terminal can listen to the first DCI according to the pre-configured listening location information. In this way, the terminal can perform corresponding dynamic data scheduling and DCI listening according to the service characteristics without being restricted by DRX under the DRX mechanism. This solves the problem that the DRX period configuration is difficult to match with the specific service due to the need to consider the comprehensive impact of multiple services in the DRX parameter configuration, which introduces unnecessary waiting transmission delay. At the same time, it can also ensure the discontinuous reception of other services.

[0371] It should be noted that in this embodiment, the terminal's application layer can identify whether the current service is the first service. When the current service is identified as the first service, the terminal can perform first DCI monitoring according to the pre-configured monitoring location information. In this way, the network-side device does not need to send the second indication information, thereby saving signaling overhead.

[0372] It should also be noted that when the network-side device does not send the second indication information, but the terminal's application layer identifies the current service, the original data transmission method can be used for data transmission before the application layer identifies the current service. For example, the initial data transmission starts with the DRX activation period.

[0373] As an optional implementation, the dedicated identifier for the first service includes at least one of the following:

[0374] A dedicated identifier corresponding to the business type of the first business;

[0375] A dedicated identifier corresponding to the first data stream of the first service.

[0376] In other words, in this optional implementation, the dedicated identifier related to the first service can be a dedicated identifier corresponding to the service type of the first service, that is, different service types correspond to different dedicated identifiers; the dedicated identifier of the first service can also be a dedicated identifier corresponding to different types of data in the same service, that is, different data streams correspond to different dedicated identifiers in the same service, for example, I-frames, P-frames and B-frames in video stream services correspond to different dedicated identifiers respectively. When the core network can indicate different encoded data streams, the network-side device can use the transmission priority of different encoded data streams to configure exclusive data stream identifiers (dedicated identifiers corresponding to encoded frames), such as X-RNTI, etc.

[0377] Furthermore, as an optional implementation, the method also includes:

[0378] The terminal receives a third indication message sent by the network-side device. The third indication message is used to indicate whether the terminal should listen to the first DCI during the DRX activation period and / or the DRX inactivation period.

[0379] In this optional implementation, the network-side device uses third indication information to instruct the terminal whether to listen to the first DCI during the DRX activation period and / or DRX inactivation period. That is, the network-side device can send third indication information to the terminal based on the first service transmission status to notify the terminal whether to listen to the first DCI during the DRX activation period and / or DRX inactivation period. In other words, when the network-side device configures at least one search space set, listening window, and listening start position for the first DCI, the network-side device can also use the third indication information to instruct the terminal whether to use at least one of the configured search space set, listening window, and listening start position to listen to the first DCI based on the first service transmission status, so as to save power consumption and reduce the waiting latency of the first service.

[0380] As a specific implementation, the third indication information is carried by at least one of the following signaling methods:

[0381] Layer 1 signaling;

[0382] Media Access Control Layer Control Unit (MAC CE);

[0383] High-level signaling.

[0384] When the first signaling is Layer 1 signaling, when the network-side device determines that the current service is the first service, the network-side device carries third indication information through the scheduled DCI signaling / unscheduled DCI signaling during the DRX activation period, instructing the terminal to listen for the first DCI during the DRX activation period and / or the DRX inactive period; alternatively, it can carry the third indication information through unscheduled DCI signaling during the DRX inactive period, instructing the terminal to listen for the first DCI during the DRX activation period and / or the DRX inactive period; or it can carry the third indication information through a power-saving signal during the DRX inactive period, instructing the terminal to listen for the first DCI during the DRX activation period and / or the DRX inactive period.

[0385] When the first signaling is MAC CE, the network-side device can carry third indication information through the MAC CE in the PDSCH during the DRX activation period to instruct the terminal to listen for the first DCI during the DRX activation period and / or the DRX inactive period; it can also carry third indication information through the SPS PDSCH during the DRX inactive period to instruct the terminal to listen for the first DCI during the DRX activation period and / or the DRX inactive period.

[0386] When the first signaling is a higher-level signaling, different values ​​can be used to instruct the terminal whether to listen for the first DCI during the DRX activation period and / or inactivation period; for example, when the value is 1, the terminal is instructed to listen for the first DCI during the DRX inactivation period, and when the value is 2 or the default value, the terminal is instructed not to listen for the first DCI during the DRX inactivation period.

[0387] The specific implementation of the data transmission method of this application embodiment will be described below with reference to specific examples:

[0388] Example 1: The first DCI uses a dedicated identifier related to the first service for scrambling. The terminal can listen to the first DCI during both the DRX activation and deactivation periods.

[0389] A service-specific identifier (a dedicated identifier for the first service) is introduced for the detection of service transmission, such as a service-specific RNTI, like X-RNTI. DCI monitoring scrambled by this service identifier RNTI is not controlled by DRX, that is, the terminal can still perform corresponding DCI monitoring during the DRX inactive period. This example uses X-RNTI as an example for illustration.

[0390] For service X (the first service), data scheduling is performed via XRNTI scrambling scheduling DCI, which can be monitored during both the active and inactive periods of the DRX. The configuration method for scheduling DCI can be the same as the existing DCI search space set configuration method, or at least one of the following methods can be used from the perspective of terminal energy saving:

[0391] Method 1: Configure multiple sets of search space set parameters for the X-RNTI scrambled DCI (first DCI), or configure multiple sets of parameters within a single search space set. For example: During DRX activation, the terminal uses search space set 1 to monitor the X-RNTI scrambled DCI; during DRX deactivation, the terminal uses search space set 2. Alternatively, the network-side device can configure search space set 1 and search space set 2 for the DRX activation and deactivation periods, respectively. Another example: Configure monitoring period 1 and monitoring period 2 in the search space set of the X-RNTI scrambled DCI, corresponding to the DRX activation and deactivation periods respectively. That is, during DRX activation, monitoring period 1 is used to monitor the X-RNTI scrambled DCI, and during DRX deactivation, monitoring period 2 is used. Sparser monitoring behavior can be configured during DRX deactivation.

[0392] Method 2: Carry terminal power-saving indication information (first indication information) in the X-RNTI scrambled DCI (first DCI), such as: listener skip indication and / or sleep indication. For example, during DRX activation, the terminal can use at least one signaling, including the first DCI containing the first indication information, Layer 1 signaling, power-saving signal, MAC layer signaling, and higher-layer signaling, to indicate subsequent listener skipping or sleep. During DRX deactivation, the terminal can use at least one signaling, including the first DCI containing the first indication information, Layer 1 signaling, power-saving signal, MAC layer signaling, and higher-layer signaling, to indicate subsequent listener skipping or sleep, thus enabling discontinuous PDCCH listening behavior, thereby saving power consumption and reducing the waiting latency of X services.

[0393] It should be noted that the method in this example can also be used to monitor the first DCI, which is scrambled using C-RNTI.

[0394] It should also be noted that the implementation method of listening to the first DCI only during the DRX activation period is similar to the implementation method of listening to the first DCI during the DRX activation period in this example.

[0395] Example 2: The first DCI uses a dedicated identifier related to the first service for scrambling, and the terminal only listens to the first DCI during the DRX inactive period:

[0396] A service-specific identifier (a dedicated identifier for the first service) is introduced for the detection of service transmission, such as a service-specific RNTI, like X-RNTI. DCI monitoring scrambled by this service identifier RNTI is not controlled by DRX, that is, the terminal can still perform corresponding DCI monitoring during the DRX inactive period. This example uses X-RNTI as an example for illustration.

[0397] For Service X (the first service), data scheduling is performed through X-RNTI scrambling DCI. The X-RNTI scrambling DCI only listens during the DRX inactive period.

[0398] The network-side equipment configures the search space for the X-RNTI scrambled DCI (first DCI) for the terminal. The specific parameters can be consistent with the search space set parameters. However, considering that the X-RNTI scrambled DCI needs to be monitored during DRX inactivity, from an energy-saving perspective, the search space for the X-RNTI scrambled DCI can also adopt one of the following methods:

[0399] Method 1: Configure the search space of the X-RNTI scrambled DCI (first DCI) with a larger listening period, where a larger value means that the listening period during the DRX inactive period is greater than the listening period during the DRX active period.

[0400] Method 2: Carry terminal power-saving indication information (first indication information) in the X-RNTI scrambled DCI (first DCI), such as: listener skip indication and / or sleep indication. For example, during DRX activation, the terminal can use at least one signaling, including the first DCI containing the first indication information, Layer 1 signaling, power-saving signal, MAC layer signaling, and higher-layer signaling, to indicate subsequent listener skipping or sleep. During DRX deactivation, the terminal can use at least one signaling, including the first DCI containing the first indication information, Layer 1 signaling, power-saving signal, MAC layer signaling, and higher-layer signaling, to indicate subsequent listener skipping or sleep, thus enabling discontinuous PDCCH listening behavior, thereby saving power consumption and reducing the waiting latency of X services.

[0401] When the terminal is in the DRX active period, the data packets of the first service are scheduled using a C-RNTI-scrambled scheduling DCI. That is, the first DCI uses C-RNTI scrambling. When timers affecting the DRX active period, such as the DRX active period timer (drx-onDurationTimer) and the DRX inactivity timer (drx-InactivityTimer), time out, the terminal enters the inactivity period. Since the first service has relatively high requirements for transmission latency, to avoid unnecessary transmission delays caused by the terminal waiting for the next DRX active period, in this optional implementation, the terminal listens to the first DCI scrambled with the dedicated identifier of the first service based on pre-configured parameters.

[0402] It should be noted that the method in this example can also be used to monitor the first DCI, which is scrambled using C-RNTI.

[0403] Example 3: The service-specific identifier X-RNTI (a dedicated identifier related to the first service) is used to indicate the listening method of the DCI (first DCI) scrambled by X-RNTI through signaling such as Layer 1 signaling / MAC layer signaling / higher layer signaling.

[0404] A service-specific identifier (a dedicated identifier related to the first service) is introduced for the detection of service transmission, such as a service-specific RNTI, like X-RNTI. DCI monitoring scrambled by this service identifier RNTI is not controlled by DRX, that is, the terminal can still perform corresponding DCI monitoring during the DRX inactive period. This example uses X-RNTI as an example for illustration.

[0405] For service X, data scheduling is performed via X-RNTI scrambling DCI. Whether the X-RNTI scrambling DCI listens during the DRX inactive period is indicated by a service-specific listening instruction. This service-specific listening instruction can be carried through signaling such as L1 / MAC layer signaling / higher-layer signaling.

[0406] The network-side equipment configures the search space for the X-RNTI-scrambled DCI (first DCI) for the terminal. The specific parameters can be consistent with the search space set parameters. The network-side equipment can send service-specific monitoring indication information (third indication information) to the terminal based on service transmission conditions to notify the terminal whether to perform X-RNTI-scrambled DCI monitoring during DRX activation and / or DRX inactivation periods. One of the following methods can be used:

[0407] Method 1: L1 signaling carries service-specific monitoring indication information (third indication information).

[0408] When the network-side equipment determines that the current service is service X, it carries a service-specific monitoring indication via scheduled DCI signaling / unscheduled DCI signaling during the DRX activation period, instructing the terminal to perform service-specific DCI monitoring during the DRX activation period and / or DRX inactivation period. Alternatively, it can carry the service-specific monitoring indication via unscheduled DCI during the DRX inactivation period, instructing the terminal to perform service-specific DCI monitoring during the DRX inactivation period. It can also carry a third indication information via energy-saving signals during the DRX inactivation period, instructing the terminal to perform first DCI monitoring during the DRX activation period and / or DRX inactivation period.

[0409] Method 2: The MAC CE carries business-specific monitoring indication information (third indication information).

[0410] Network-side devices can carry service-specific listening instructions in the MAC CE of the PDSCH during the DRX activation period, instructing terminals to perform service-specific DCI (first DCI) listening during the DRX activation and / or DRX inactivation periods. They can also carry service-specific instructions in the SPS PDSCH during the DRX inactivation period, instructing terminals to perform service-specific DCI listening during the DRX inactivation period.

[0411] Method 3: Higher-level signaling carries service-specific monitoring instructions (third instruction information).

[0412] Network-side devices configure service-specific listening indication information through higher-layer signaling. When the value is the first value (e.g., the first value is 1), the terminal is instructed to perform service-specific DCI listening during the DRX inactive period. When the value is the second value (e.g., the second value is 2) or the default value is used, the terminal is instructed not to perform service-specific DCI listening during the DRX inactive period.

[0413] It should be noted that for the first DCI scrambled with C-RNTI, the method in this example can also be used to indicate the listening mode.

[0414] Example 4: Configure network-side devices with service-specific listening location information, namely the listening location information of the first DCI (including listening window and / or listening start location information).

[0415] Configure a service-specific second listening location information during the DRX inactive period. During the DRX active period, the terminal listens according to the DCI search space configured during the active period; during the DRX inactive period, the terminal performs scheduled DCI (first DCI) listening according to the pre-configured second listening location information.

[0416] Network-side devices pre-configure X service-specific listening location information during the DRX activation period and / or DRX inactivation period via higher-layer signaling. For the X service-specific listening location information, one or more combinations of the following parameters can be used for configuration:

[0417] Configure the listening start time using the listening periodicity and offset;

[0418] Start time T of the listening window start ;

[0419] Listen duration

[0420] End time T final ;

[0421] The time interval T between adjacent listening windows offset ;

[0422] Inactive period listening start position / number of listening windows;

[0423] Activation period monitoring start position / number of monitoring windows;

[0424] The offset value from the start / end position of the existing first action is used as the listening start time. The first action includes periodic or semi-persistent actions, such as: periodic CSI / RRM / RLM measurements, the time slot where the SPS PDSCH is located, the time slot where the HARQ-ACK feedback of the SPSPDSCH is located, the start or end position of the RTT timer of the SPS PDSCH, the start / end position of the DRX cycle / activation period, and periodic reference signals such as SSB / CSI-RS / TRS. The first action also includes non-periodic actions, such as: downlink signaling, CSI measurements, and reference signals such as CSI-RS and TRS.

[0425] The following examples illustrate how to configure the listening window and / or the starting position of the listening parameters:

[0426] Example 1: Configure the listening start time by using the listening period and offset, for example: the start time meets the following conditions: Where, n f Frame number The slot number under subcarrier μ, k is the number of time slots contained in the next subframe of subcarrier μ. s For the listening period, o s This is the first offset value. Additionally, if the listener duration is configured, one or more listener windows can be determined. This can also be combined with configuring the time interval T between adjacent listener windows. offset And / or the starting position of DRX inactive / DRX active period monitoring / number of monitoring windows, to determine multiple monitoring windows.

[0427] Example 2: Configuring the absolute start time T of the listening window start and the listening termination time T final Alternatively, the listening duration can be used to define a listening window. Additionally, if a time interval T between adjacent listening windows is configured... offset And / or the number of listening start positions / listening windows can determine multiple listening windows.

[0428] Example 3: The listener window or listener start position can be set as the listener start time by offsetting the start / end position of an existing periodic behavior. This offset can be an offset position after or before the start / end position of the periodic behavior.

[0429] When a network-side device receives an X service indication from the core network, or identifies a downlink data service indication as an X service, the network-side device can notify the terminal that the current service is an X service through the X service indication information (third indication information). Alternatively, the terminal application layer can identify the current service as an X service. It should be noted that before the terminal application layer identifies the service, the original data transmission scheme is used, such as data transmission starting from the DRX activation period.

[0430] When the data transmission service is an X service, the terminal can perform DCI scheduling for the X service during the DRX activation period and / or DRX inactivation period according to the pre-configured listening window or listening opportunity.

[0431] From an energy-saving perspective, the following methods can also be adopted:

[0432] The first DCI carries a terminal power-saving indication (first indication information), such as a listening skip indication and / or a sleep indication. For example, during the DRX inactivity period, the terminal can use at least one signaling instruction, including the first DCI containing the first indication information, Layer 1 signaling, power-saving signals, MAC layer signaling, and higher layer signaling, to instruct the terminal to perform discontinuous DCI listening behavior, thereby saving power consumption and reducing the waiting latency of X services.

[0433] Example 5: DCI scrambled with X-RNTI (the dedicated identifier for the first service) is only monitored during the listening window and / or the start position of the listening during the DRX inactivity period.

[0434] Network-side devices configure a service-specific identifier, such as X-RNTI, for the scheduling DCI of service X. X-RNTI-scrambled DCIs are not restricted by DRX inactivity periods, meaning they can be monitored during DRX inactivity. X-RNTI-scrambled DCIs can be monitored during DRX activation periods, or not; see Examples 1 and 2 for details.

[0435] When the terminal is in the DRX inactive period, the terminal listens for X-RNTI scrambled DCI at the pre-configured listening window and / or listening start position. For details, please refer to Implementation 4.

[0436] Example 6: The dedicated identifier for the primary service can also be extended to different types of data transmission within the same service, such as I-frames, P-frames, and B-frames in video streaming services. When the core network can indicate data streams with different encodings, network-side devices can utilize the transmission priority of these different encoded data streams to configure dedicated service stream identifiers, such as X-RNTI. Specific transmission schemes can be found in Examples 1 through 5.

[0437] Example 7: The size of the listening window for service X can be dynamically adjusted based on the first piece of information.

[0438] Configure service-specific listening location information during DRX inactivity. For example: During DRX activation, the terminal listens according to the PDCCH search space configured during activation; during DRX inactivity, the terminal schedules DCI listening according to the pre-configured listening location information (listening window or listening start position).

[0439] Meanwhile, the network-side equipment configures the terminal with first information, which indicates the duration for which the terminal will continue to listen after detecting the service-specific DCI.

[0440] The first piece of information can be carried through L1 signaling, MAC signaling, or higher-layer signaling. For example, the first piece of information can be a listener timer or its duration, an indication signaling message, or a reference signal. Taking a listener timer as an example, when the listener timer has not expired, the terminal can continue to perform service-specific DCI listening. When service data packets are transmitted at the end of the listening window due to latency jitter, the data packets need to wait for the next listening window or listening opportunity before they can be transmitted because there are no subsequent listening opportunities. Configuring a listener timer helps reduce the transmission latency caused by latency jitter.

[0441] Once the network-side device completes data transmission, it instructs the terminal to skip listening or go into sleep mode via the first indication information. The specific process is the same as in Implementations 1 to 4.

[0463] Location information associated with the first line;

[0464] Independent listening location information.

[0473] Layer 1 signaling;

[0476] In this embodiment of the data transmission apparatus, the generation unit 401 generates a first DCI including scheduling information of a first service, and the first sending unit 402 sends the first DCI to the terminal during the DRX activation period and / or inactivation period. This ensures that the first DCI carries only the scheduling information of the first service, enabling the data transmission apparatus to configure dedicated data transmission information for the terminal. Furthermore, sending the first DCI to the terminal during the DRX activation period and / or inactivation period allows the terminal to listen for the first DCI during discontinuous reception of the DRX activation period and / or DRX inactivation period. Thus, the terminal can perform dynamic data scheduling and DCI listening based on service characteristics without being restricted by the DRX mechanism, thereby solving the problem that the current DRX parameter configuration requires consideration of the combined effects of multiple services, making it difficult to match the DRX cycle configuration with specific services and introducing unnecessary waiting transmission delays. Simultaneously, it also ensures discontinuous reception of other services.
