Abstract
Description
Downlink control information DCI transmission method, communication device and storage medium Technical Field
[0001] The present disclosure relates to the field of communication technologies, and in particular to a downlink control information (DCI) transmission method, communication equipment, communication system, and storage medium. Background Art
[0002] With the development of communication technology, cell-discontinuous transmission (Cell-DTX) and cell-discontinuous reception (Cell-DRX) have been proposed. When Cell-DTX is activated, the cell will perform downlink transmission during the activation period of Cell-DTX and will not perform downlink transmission during the inactivation period of Cell-DTX. When Cell-DRX is activated, the cell will perform uplink reception during the activation period of Cell-DRX and will not perform uplink reception during the inactivation period of Cell-DRX, thereby achieving cell energy saving. Cell energy saving can also be called network energy saving (NES). In some cases, the cell can perform network energy saving through intermittent sleep.

[0026] Embodiments of the present disclosure provide a downlink control information (DCI) transmission method, a communication device, a communication system, and a storage medium.
[0027] A first aspect provides a downlink control information (DCI) transmission method, performed by a terminal, the method comprising:
[0028] A DCI monitoring period is determined according to at least one of a discontinuous transmission DTX and a discontinuous reception DRX of at least one serving cell of the terminal.
[0029] Based on the above scheme, the period for transmitting DCI is determined according to the relevant conditions of DTX and / or DRX of at least one serving cell of the terminal, rather than limiting the transmission of DCI to a certain period of cell DTX and / or DRX and / or a specific period of terminal DRX, or directly exiting the cell DTX, cell DRX and / or terminal DRX when DCI is sent. Therefore, on the one hand, the transmission of DCI can be realized, and on the other hand, the power consumption of the terminal and / or cell can be saved as much as possible.
[0030] In some embodiments of the first aspect, the DCI includes a group-common DCI.
[0031] This DCI is group-common DCI. Since group-common DCI needs to be monitored by one or more terminal groups, and a terminal group may include one or more terminals, this method is used to determine the DCI monitoring period instead of uniformly limiting it to a specific period. This makes the operation of network equipment simpler and, at the same time, can achieve maximum energy saving for terminals and cells while implementing DCI transmission.
[0032] In some embodiments of the first aspect, determining a DCI monitoring period according to at least one of discontinuous transmission (DTX) and discontinuous reception (DRX) of at least one serving cell of the terminal includes at least one of the following:
[0033] Determining a DCI monitoring period according to an activation status of at least one of DTX and DRX of at least one serving cell of the terminal;
[0034] The DCI monitoring period is determined according to a configuration of at least one of DTX and DRX of at least one serving cell of the terminal.
[0035] In some embodiments, the terminal determines the DCI monitoring period based on the DTX and DRX configuration and / or activation status of at least one of its own serving cells, so that subsequent network equipment can choose a method to implement it based on network requirements, network busyness, and network power consumption.
[0036] In some embodiments of the first aspect, determining a DCI monitoring period according to an activation status of at least one of DTX and DRX of at least one serving cell of the terminal includes at least one of the following:
[0037] Determining a DCI monitoring period according to an activation status of at least one of DTX and DRX of a first cell; the first cell being a cell configured to send DCI in a serving cell of the terminal;
[0038] Determine a DCI monitoring period according to an activation status of at least one of DTX and DRX of any one or more serving cells of the terminal;
[0039] The DCI monitoring period is determined according to the activation status of at least one of DTX and DRX of all second cells of the terminal; the second cell is a serving cell configured with at least one of DTX and DRX by the terminal.
[0040] In the embodiment of the present disclosure, the DCI monitoring period is determined according to the activation status of DTX and / or DRX of the first cell or any cell of the terminal, thus disclosing at least two optional methods, which facilitates flexible selection and use according to subsequent needs.
[0041] In some embodiments of the first aspect, determining the DCI monitoring period according to an activation status of at least one of DTX and DRX of the first cell includes at least one of the following:
[0042] At least one of DTX and DRX of the first cell is activated, and determining that both an activation period and an inactivation period of discontinuous reception (DRX) of the terminal are DCI monitoring periods;
[0043] At least one of DTX and DRX of the first cell is activated, determining an activation period and an inactivation period of DTX of the first cell as a DCI monitoring period;
[0044] At least one of DTX and DRX of the first cell is not activated, determining that the DRX activation period of the terminal is a DCI monitoring period;
[0045] When at least one of DTX and DRX of the first cell is not activated, a non-activation period of DTX of the first cell is determined as a monitoring period of DCI.
[0046] Based on the above scheme, several specific implementation methods are provided above. The terminal can flexibly set the DCI monitoring period according to the DTX and DRX activation status of the first cell. On the one hand, it can ensure that DCI is monitored in time, and on the other hand, it can minimize the power consumption of the terminal and / or cell.
[0047] In some embodiments of the first aspect, determining a DCI monitoring period according to an activation status of at least one of DTX and DRX of any one or more serving cells of the terminal includes at least one of the following:
[0048] Determining, based on at least one of DTX and DRX of any one or more serving cells of the terminal being inactive, that the DTX activation period of the first cell is a DCI monitoring period;
[0049] Determining, based on at least one of DTX and DRX of any one or more serving cells of the terminal being inactive, that the DRX activation period of the terminal is a DCI monitoring period;
[0050] Determining, based on at least one of DTX and DRX of all serving cells of the terminal being activated, an activation period and an inactivation period of DTX of the first cell as a DCI monitoring period;
[0051] According to at least one of DTX and DRX of all serving cells of the terminal being activated, an activation period and an inactivation period of DRX of the terminal are determined as a monitoring period of DCI.
[0052] Based on the above scheme, several specific implementation methods are provided above. The terminal can flexibly set the DCI monitoring period according to the DTX and DRX activation status of any serving cell of the terminal. On the one hand, it can ensure that the DCI is monitored in time, and on the other hand, it can minimize the power consumption of the terminal and / or cell.
[0053] In some embodiments of the first aspect, determining a DCI monitoring period according to a configuration of at least one of DTX and DRX of at least one serving cell of the terminal includes:
[0054] When at least one third cell of the terminal is not configured with DTX and DRX, the activation period of the DTX of the first cell or the activation period of the DRX of the terminal is determined to be the monitoring period of DCI; the first cell is a cell in the service cell of the terminal that is configured to send DCI; the third cell is a service cell of the terminal that is different from the first cell.
[0055] Or for the purpose of saving power consumption of the terminal, the DCI is monitored during the activation period of DTX of the first cell or the activation period of DRX of the terminal.
[0056] Based on the above solution, when at least one third cell of the terminal is not configured with DTX and DRX, the terminal can use the second demand communication, so that the cell configured with DTX and / or DRX is not exited from DTX and / or DRX based on monitoring DCI. In this way, the power consumption of the network can be reduced as much as possible while ensuring timely transmission of services.
[0057] In some embodiments, the third cell not configured with DTX and DRX may be a primary cell or a secondary cell of the terminal. Since there is at least one third cell not configured with DTX and DRX, when the terminal has service data to transmit, it can directly transmit it in the third cell not configured with DTX and DRX. Therefore, the terminal can send data on the third cell and monitor DCI during the DTX activation period of the first cell or the DRX activation period of the terminal.
[0058] In some embodiments of the first aspect, when at least one third cell of the terminal is not configured with DTX and DRX, determining the activation period of DTX of the first cell or the activation period of DRX of the terminal as a DCI monitoring period includes:
[0059] When at least one third cell of the terminal is not configured with DTX and DRX and the third cell not configured with DTX and DRX is activated, the activation period of DTX of the first cell or the activation period of DRX of the terminal is determined as the monitoring period of DCI.
[0060] Since there is at least one third cell that is not configured with DTX and DRX, and the third cell that is not configured with DTX and DRX is a secondary cell, it is necessary to determine whether the third cell is activated. The terminal transmission will be executed only when the secondary cell is activated. Therefore, in order to ensure the timeliness of the terminal's service transmission, it is determined to monitor DCI during the activation period of the first cell's DTX and the activation period of the terminal's DRX, so as to ensure successful DCI monitoring while minimizing the power consumption of the terminal and / or cell.
[0061] In some embodiments of the first aspect, at least one third cell of the terminal is not configured with DTX and / or DRX, the third cell not configured with DTX and / or DRX is activated, and the activated BWP of the third cell not configured with DTX and / or DRX is not a dormant BWP, and the activation period of the DTX of the first cell or the activation period of the DRX of the terminal is determined as the listening period of the DCI.
[0062] In some embodiments of the first aspect, when at least one third cell of the terminal is not configured with DTX and DRX, determining the activation period of DTX of the first cell or the activation period of DRX of the terminal as a DCI monitoring period includes:
[0063] When at least one secondary cell of the terminal is not configured with DTX and DRX, the secondary cell not configured with DTX and DRX is activated, and the secondary cell not configured with DTX and DRX has no dormancy behavior, the activation period of the first cell DTX or the activation period of the terminal DRX is determined as the DCI monitoring period.
[0064] In some embodiments of the first aspect, determining the DCI monitoring period according to an activation status of at least one of DTX and DRX of all second cells of the terminal includes at least one of the following:
[0065] When at least one of DTX and DRX of all second cells of the terminal is activated, determine that both the inactive period and the active period of DTX of the first cell are monitoring periods of DCI;

[0067] When at least one of DTX and DRX of all second cells of the terminal is activated, determining that both the inactive period and the active period of DRX of the terminal are monitoring periods of DCI;
[0068] When at least one of the DTX and the DRX of all the second cells of the terminal is not activated, it is determined that the DTX activation period of the DRX of the terminal is a DCI monitoring period.
[0069] The above solution determines the DCI monitoring period based on the activation status of DTX and / or DRX of all the second cells of the terminal, taking into account both the success of DCI monitoring and the power consumption saving of the terminal. In some embodiments of the first aspect, the DCI is used to indicate at least one of the following:

[0141] FIG1A is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.
[0142] As shown in Figure 1A, a communication system 100 includes a terminal 101 and a network device 102. The network device 102 may include an access network device and / or a core network device.
[0143] In some embodiments, the terminal 101 includes, for example, a mobile phone, a wearable device, an Internet of Things device, a car with communication function, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and at least one of a wireless terminal device in a smart home, but is not limited thereto.
[0144] In some embodiments, the terminal is also referred to as User Equipment (UE).
[0145] In some embodiments, the access network device may be, for example, a node or device that accesses a terminal to a wireless network. The access network device may include an evolved NodeB (eNB), a next generation evolved NodeB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved nodeB (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an open base station (Open RAN), a cloud base station (Cloud RAN), a base station in other communication systems, and at least one of an access node in a Wi-Fi system, but is not limited thereto.
[0146] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.
[0147] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.
[0148] In some embodiments, the core network device may be a single device including a first network element, or may be a plurality of devices or a group of devices, each including a first network element. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).
[0149] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution provided by the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution provided by the embodiment of the present disclosure is also applicable to similar technical problems.
[0150] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1A are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include entities other than those shown in Figure 1A. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.
[0151] The embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other downlink control information (DCI) transmission methods, and next-generation systems based on these. Furthermore, multiple systems may be combined (for example, a combination of LTE and NR).
[0152] In the perception scenario, the AF or client on the terminal can request the core network to disclose the perception results. In order to facilitate the AF / client on the terminal to analyze or process the perception results, it may also be necessary to provide the perception context to the AF / client on the terminal. The perception context can be requested by the AF / client on the UE or actively provided by the core network. The perception context may include map information, area information, capture time, UE location and ID. This context information may be required when combining the perception results with data from sources other than 5GS. If the terminal is identifiable, the terminal location information is sensitive, and certain information of the terminal should not be disclosed without the consent of the terminal. For example, the user ID of the terminal is a permanent user ID and should not be disclosed without the user's consent.
[0153] In current user consent mechanisms, user consent is based on the UE ID provided by the AF / client on the UE requesting the UE's location to verify the user's consent to the disclosure of certain terminal information. However, in a sensing scenario, the AF / client on the UE may not provide the UE ID in the sensing request. The UE location and user ID are included in the sensing context, not in the sensing request or sensing result. Therefore, the current user consent mechanism for authorizing the disclosure of UE location information does not work within the sensing area. Furthermore, there is no existing mechanism to authorize the disclosure of UE location information in the sensing context.
[0154] In view of this, as shown in FIG2 , an embodiment of the present disclosure provides a DCI transmission method, which is performed by a communication system. The method may include:
[0155] S2101: The network device determines a DCI transmission period.
[0156] In some embodiments, the network device may be an access network device.
[0157] In some embodiments, the network device determines the DCI transmission period according to at least one of the DTX and DRX of at least one serving cell of the terminal.
[0158] In some embodiments, the DCI transmission period may be: a period for transmitting the DCI.
[0159] In some embodiments, the relevant situation may include, but is not limited to, at least one of the following: a configuration situation and / or an activation situation.
[0160] In some embodiments, the configuration status may indicate whether at least one serving cell of the terminal is configured with DTX and / or DRX.
[0161] In some embodiments, the activation status may indicate whether DTX and / or DRX of at least one serving cell of the terminal is activated.
[0162] In some embodiments, if DTX of a serving cell is activated, the serving cell performs downlink transmission during the DTX activation period and does not perform downlink transmission during the DTX inactive period. When downlink transmission is not performed during the DTX inactive period of the serving cell, the serving cell may enter a low power consumption state to save energy.
[0163] For example, as shown in FIG1B , the DTX cycle corresponding to the cell DTX may include an active period and a non-active period.
[0164] For example, as shown in FIG1B , the DTX cycle corresponding to the cell DTX may include an active period and a non-active period.
[0165] In some embodiments, if DRX is activated for a serving cell, the serving cell performs uplink reception during the DRX activation period and does not perform uplink reception during the DRX inactive period. When not performing uplink reception during the DRX inactive period, the serving cell may enter a low power consumption state to save energy.
[0166] For example, as shown in FIG1C , the DRX cycle corresponding to the cell DRX may include an active period and a non-active period.
[0167] In some embodiments, S2101 may include: determining a DCI transmission period according to an activation status of at least one of DTX and DRX of at least one serving cell of the terminal.
[0168] The terminal may be a terminal that supports carrier aggregation, dual connectivity, or multi-connectivity. In this case, the terminal may have one or more serving cells. For example, the serving cells of the terminal may include a primary cell (Pcell) and a secondary cell (Scell).
[0169] Specifically, the DCI monitoring period is determined according to the activation status of at least one of DTX and DRX of the first cell.
[0170] In some embodiments, the first cell is a cell in a serving cell of the terminal that is configured to send DCI.
[0171] In some embodiments, the network device may configure the first cell via a broadcast message, a multicast message, or a unicast message.
[0172] In some embodiments, the broadcast message may include a system message or the like.
[0173] In some embodiments, the network device configures the first cell using a Radio Resource Control (RRC) message.
[0174] In some embodiments, the network device configures the first cell using an RRC-specific message.
[0175] In some embodiments, the first cell may be a primary cell or a secondary cell of the terminal.
[0176] In some embodiments, the first cell may be a cell in which the largest number of terminals reside in the terminal group where the current terminal is located.
[0177] In some embodiments, the first cell may be a cell where all terminals in the terminal group to which the current terminal belongs reside.
[0178] In some embodiments, at least one of DTX and DRX of the first cell is activated, and it is determined that both the activation period and the inactivation period of the discontinuous reception (DRX) of the terminal are DCI transmission periods.
[0179] For example, if DTX is activated for the first cell, it means that the first cell does not perform downlink transmission during the DTX inactive period. If the serving cell needs to send DCI at this time, it is likely that the data is for urgent transmission. Therefore, the DCI transmission period can be determined during the terminal's DRX active and inactive periods. For example, DCI can be used for the first cell DTX that is not activated.
[0180] For example, if the DRX function of the first cell is activated, this means that the first cell does not perform uplink reception during the DRX inactive period. If the serving cell needs to send DCI at this time, it is likely that the data is for urgent transmission. Therefore, the DCI transmission period can be determined during the terminal's DRX active and inactive periods. For example, DCI can be used for the first cell's DRX that is not activated.
[0181] In some embodiments, at least one of DTX and DRX of the first cell is activated, and it is determined that both the activation period and the inactivation period of the discontinuous reception (DRX) of the terminal are DCI transmission periods.
[0182] The terminal DRX may include: the DRX of the terminal in the RRC connected state. The DRX of the terminal in the RRC connected state may be referred to as the terminal connected discontinuous reception (C-DRX).
[0183] In some embodiments, at least one of DTX and DRX of the first cell is activated, and the activation period and the inactivation period of DTX of the first cell are determined as the DCI transmission period.
[0184] If both the activation period and the activation period of the first cell DTX are determined as the sending period, it is convenient for the network device to send the DCI in a timely manner, thereby ensuring the timely sending of the DCI.
[0185] In some embodiments, at least one of DTX and DRX of the first cell is not activated, and the activation period of DRX of the terminal is determined to be a DCI transmission period.
[0186] If the DRX activation period of the terminal is determined as the DCI transmission period, the terminal can receive the DCI while continuing to maintain DRX, thereby ensuring the energy saving effect of the terminal as much as possible.
[0187] In some embodiments, at least one of DTX and DRX of the first cell is not activated, and the activation period of DTX of the first cell is determined to be a period for sending DCI.
[0188] If at least one of the DTX and DRX of the first cell is not activated, it means that there is no emergency transmission at present, so DCI can be sent during the activation period of DTX of the first cell, and energy saving of the network device can be given priority.
[0189] In some embodiments, S2101 may include: determining a DCI transmission period according to an activation status of at least one of DTX and DRX of any one or more serving cells of the terminal.
[0190] In some embodiments, a terminal supports carrier aggregation, dual connectivity, or multi-connectivity. In this case, the terminal may have multiple serving cells. These serving cells may include: a primary cell and a secondary cell. In some embodiments, the secondary cell may further include: a primary secondary cell and a normal secondary cell.
[0191] In some embodiments, the aforementioned first cell may be a primary cell or a primary-supplementary cell.
[0192] In other embodiments, the aforementioned first cell may be any designated serving cell.
[0193] Assuming that the terminal is configured with M serving cells, S2101 may determine the DCI transmission period according to the activation status of DTX and / or DRX of one or more serving cells among the M serving cells.
[0194] In some embodiments, based on at least one of DTX and DRX of any one or more serving cells of the terminal being not activated, the DTX activation period of the first cell is determined to be the DCI transmission period.
[0195] In some embodiments, according to the fact that at least one of DTX and DRX of any one or more serving cells of the terminal is not activated, the activation period of DRX of the terminal is determined to be the transmission period of DCI.
[0196] In some embodiments, according to at least one of DTX and DRX of all serving cells of the terminal being activated, the DTX activation period and the DTX inactivation period of the first cell are determined as the DCI transmission period.
[0197] In some embodiments, according to at least one of DTX and DRX of all serving cells of the terminal being activated, the activation period and the inactivation period of DRX of the terminal are determined as the DCI transmission period.
[0198] In some embodiments, S2101 may include: determining a DCI transmission period according to a configuration of at least one of DTX and DRX of at least one serving cell of the terminal.
[0199] In some embodiments, if at least one service cell of the terminal is not configured with DTX and / or DRX, it means that at least one service cell will not periodically stop uplink transmission or downlink reception. In this way, even if there is an emergency transmission, it can be performed on a cell that is not configured with DRX and / or DTX. Therefore, the DCI sending period at this time can be based on whether one or more service cells are configured with DTX and / or DRX.
[0200] In some embodiments, when at least one serving cell of the terminal is not configured with DTX and / or DRX, the activation period of DTX of the first cell or the inactivation period of DRX of the terminal is determined as the transmission period of DCI.
[0201] In some embodiments, when at least one serving cell of the terminal is not configured with DTX and / or DRX and a cell not configured with DTX and / or DRX is activated, the activation period of the first cell DTX or the activation period of the terminal DRX is determined as the DCI transmission period.
[0202] Exemplarily, the activation of a cell that is not configured with DTX and / or DRX may be understood as: the cell can provide communication services for the terminal.
[0203] Exemplarily, the activation of a cell that is not configured with DTX and / or DRX may be understood as: the cell may be used as a serving cell for the terminal after being activated.
[0204] In some embodiments, S2101 may include: determining a DCI transmission period according to an activation status of at least one of DTX and DRX of all second cells of the terminal.
[0205] In some embodiments, the second cell is a serving cell configured with at least one of DTX and DRX for the terminal.
[0206] In some embodiments, some of the terminal's serving cells are configured with DRX and / or DTX, while some of the terminal's serving cells are not configured with DRX and / or DTX. In some embodiments, for example, the terminal's serving cells may be divided into one or more cell groups. Each serving cell within some cell groups is configured with at least one of DRX and DTX, while each serving cell within some cell groups is not configured with DTX and DRX. For example, the terminal's cell group may include: a primary cell group and / or a secondary cell group. The primary cell group may be the cell group where the terminal's primary cell is located. The secondary cell group may be a cell group consisting entirely of secondary cells of the terminal. In some other embodiments, the cell group may be a special cell group. The special cell group may include a primary cell and a primary and secondary cell.
[0207] In this case, the DCI transmission period can be determined according to the activation status of all serving cells configured with DRX and / or DTX of the terminal, so as to ensure successful DCI transmission while minimizing the power consumption of the terminal and the cell.
[0208] In some embodiments, when at least one third cell of the terminal is not configured with DTX and / or DRX, the activation period of DTX of the first cell or the activation period of DRX of the terminal is determined as the transmission period of DCI. The third cell is different from the first cell. The third cell is one of the serving cells of the terminal.
[0209] In some embodiments, if at least one third cell of the terminal is not configured with DTX and / or DRX, if emergency data is to be transmitted to the terminal, it can be transmitted on the third cell that is not configured with DTX and / or DRX. At this time, the DCI sending period can be determined to be during the activation period of DTX in the first cell to save the power consumption of the first cell as much as possible.
[0210] In some embodiments, if at least one third cell of the terminal is not configured with DTX and / or DRX, if emergency data is to be transmitted to the terminal, it can be transmitted on the third cell that is not configured with DTX and / or DRX. At this time, the DCI sending period can be determined to be during the activation period of the terminal DRX to save the terminal's power consumption as much as possible.
[0211] In some embodiments, the third cell is different from the first cell. The third cell may be a serving cell of the terminal different from the first cell.
[0212] In some embodiments, if the third cell that is not configured with DRX and / or DTX is a secondary cell, it is also necessary to determine whether the secondary cell has a dormant behavior. For example, the dormant behavior includes: the activated BWP of the third cell is a dormant BWP. When the third cell that is not configured with DRX and / or DTX is activated and does not have a dormant behavior, the activation period of the first cell DTX or the activation period of the terminal DRX is used as the DCI transmission period. In some embodiments, the determination of the DCI transmission period based on the activation status of at least one of the DTX and DRX of all the second cells of the terminal includes at least one of the following:
[0213] When at least one of DTX and DRX of all second cells of the terminal is activated, determine that both the inactive period and the active period of DTX of the first cell are transmission periods of the DCI;
[0214] When at least one of DTX and DRX of all second cells of the terminal is not activated, determine an activation period of DTX of the first cell as a transmission period of the DCI;
[0215] When at least one of the DTX and the DRX of all the second cells of the terminal is activated, determining that both the inactive period and the active period of the DRX of the terminal are the transmission period of the DCI;
[0216] When at least one of the DTX and the DRX of all the second cells of the terminal is not activated, determining the activation period of the DTX of the DRX of the terminal as the transmission period of the DCI.
[0217] When not all second cells have at least one of DTX and DRX activated, it means that there is a second cell that can provide communication services to the terminal in a timely manner. Therefore, the activation period of the first cell DTX or the activation period of the terminal's DRX can be used as the DCI sending period. Otherwise, the activation period and the inactivation period of the first cell DTX, or the inactivation period and the activation period of the terminal's DRX can be used as the DCI sending period.
[0218] In some embodiments, the DCI is used to indicate at least one of the following:
[0219] A first indication, used to indicate activation or deactivation of DTX of at least one serving cell of the terminal;
[0220] A second indication is used to indicate activation or deactivation of DRX of at least one serving cell of the terminal;
[0221] The third indication is used to trigger conditional switching of at least one serving cell of the terminal.
[0222] In some embodiments, S2101 may include: determining a transmission period of a group common DCI.
[0223] In some embodiments, the format of the DCI is 2-9.
[0224] In some embodiments, DCI uses a cell discontinuous transmission / reception DTRX-radio network temporary identifier RNTI.
[0225] In some embodiments, cellDTRX-RNTI may also be referred to as NES RNTI.
[0226] In some embodiments, FIG1D is a schematic diagram of a format of DCI.
[0227] The DCI shown in FIG1D includes indication bits indicating whether DTX of one or more serving cells of the terminal is activated or not, whether DRX of the serving cell is activated or not, and whether conditional handover (HO) is triggered or not.
[0228] The DCI shown in Figure 1D is group-common DCI. Group-common DCI can be used for one or more terminals within a terminal group. The terminal can also be called a user equipment (UE). As shown in Figure 1D, both terminal 1 and terminal 2 will receive the group-common DCI. The serving cells of terminal 1 include cells 1 to 5, and cell 1 is the primary cell of the terminal. The serving cells of terminal 2 include cells 1, 2, 4, and 6, and cell 2 is the primary cell of the terminal.
[0229] Of course, the above is just an example of DCI, and the specific implementation is not limited to the above example.
[0230] S2102: The network device sends DCI.
[0231] In some embodiments, the network device transmits the DCI during a determined transmission period.
[0232] S2103: The terminal determines a DCI monitoring period.
[0233] In some embodiments, the listening period may correspond to the aforementioned sending period. The terminal may determine the listening period in the same or similar manner as the network device determines the DCI sending period.
[0234] The DCI monitoring period may be a period during which the terminal monitors DCI. Compared to a dormant state of the terminal, the period during which the terminal monitors DCI is a state with lower power consumption.
[0235] In some embodiments, S2103 may include: determining a DCI monitoring period according to at least one of a discontinuous transmission (DTX) and a discontinuous reception (DRX) of at least one serving cell of the terminal.

[0237] In some embodiments, the configuration status may indicate whether at least one serving cell of the terminal is configured with DTX and / or DRX.
[0238] In some embodiments, the activation status may indicate whether DTX and / or DRX of at least one serving cell of the terminal is activated.

[0241] In some embodiments, determining a DCI monitoring period based on an activation status of at least one of DTX and DRX of at least one serving cell of the terminal includes: determining the DCI monitoring period based on an activation status of at least one of DTX and DRX of a first cell. The first cell is a cell configured to send DCI among the serving cells of the terminal.
[0242] In some embodiments, determining a DCI monitoring period according to an activation status of at least one of DTX and DRX of the first cell includes:
[0243] In some embodiments, at least one of DTX and DRX of the first cell is activated, and it is determined that both the activation period and the inactivation period of the discontinuous reception DRX of the terminal are monitoring periods of DCI;
[0244] In some embodiments, at least one of DTX and DRX of the first cell is activated, and an activation period and an inactivation period of DTX of the first cell are determined as a monitoring period of DCI;

[0246] In some embodiments, at least one of DTX and DRX of the first cell is not activated, and a non-DTX activation period of the first cell is determined as a DCI monitoring period.
[0247] In some embodiments, the monitoring period of DCI is determined based on the activation status of at least one of DTX and DRX of at least one service cell of the terminal, including: determining the monitoring period of DCI based on the activation status of at least one of DTX and DRX of any one or more service cells of the terminal.

[0252] In some embodiments, when at least one service cell of the terminal is not configured with DTX and / or DRX, the activation period of the first cell DTX or the activation period of the terminal DRX is determined as the monitoring period of DCI; the first cell is the cell in the service cell of the terminal that is configured to send DCI.
[0253] In some embodiments, when at least one third cell of the terminal is not configured with DTX and / or DRX, the activation period of DTX of the first cell or the activation period of DRX of the terminal is determined as the monitoring period of DCI. The third cell is different from the first cell. The third cell is one of the serving cells of the terminal.
[0254] In some embodiments, if at least one third cell of the terminal is not configured with DTX and / or DRX, if emergency data is to be transmitted to the terminal, it can be transmitted on the third cell that is not configured with DTX and / or DRX. At this time, the listening period of the DCI can be determined to be the activation period of the DTX of the first cell to save the power consumption of the first cell as much as possible.
[0255] In some embodiments, if at least one third cell of the terminal is not configured with DTX and / or DRX, if emergency data is to be transmitted to the terminal, it can be transmitted on the third cell that is not configured with DTX and / or DRX. At this time, the listening period of the DCI can be determined to be during the activation period of the terminal DRX to save the power consumption of the terminal as much as possible.
[0256] In some embodiments, the third cell is different from the first cell. The third cell may be a serving cell of the terminal different from the first cell.
[0257] In some embodiments, if a third cell not configured with DRX and / or DTX is a secondary cell, it is also necessary to determine whether the secondary cell has a dormant behavior. For example, the dormant behavior may include: the activated BWP of the third cell is a dormant BWP. If the third cell not configured with DRX and / or DTX is activated and does not have a dormant behavior, the DTX activation period of the first cell or the terminal DRX activation period is used as the DCI monitoring period.
[0258] In some embodiments, S2101 may include: determining a DCI monitoring period according to an activation status of at least one of DTX and DRX of all second cells of the terminal.
[0259] In some embodiments, the second cell is a serving cell configured with at least one of DTX and DRX for the terminal.
[0260] In some embodiments, some of the terminal's serving cells are configured with DRX and / or DTX, while some of the terminal's serving cells are not configured with DRX and / or DTX. In some embodiments, for example, the terminal's serving cells may be divided into one or more cell groups. Each serving cell within some cell groups is configured with at least one of DRX and DTX, while each serving cell within some cell groups is not configured with DTX and DRX. For example, the terminal's cell group may include: a primary cell group and / or a secondary cell group. The primary cell group may be the cell group where the terminal's primary cell is located. The secondary cell group may be a cell group consisting entirely of secondary cells of the terminal. In some other embodiments, the cell group may be a special cell group. The special cell group may include a primary cell and a primary and secondary cell.
[0261] In this case, the DCI monitoring period can be determined according to the activation status of all serving cells configured with DRX and / or DTX of the terminal, so as to ensure successful DCI transmission while minimizing the power consumption of the terminal and the cell.
[0262] In some embodiments, determining the DCI monitoring period according to an activation status of at least one of DTX and DRX of all second cells of the terminal includes at least one of the following:
[0263] When at least one of DTX and DRX of all second cells of the terminal is activated, determine that both the inactive period and the active period of DTX of the first cell are monitoring periods of the DCI;
[0264] When at least one of DTX and DRX of all second cells of the terminal is not activated, determining an activation period of DTX of the first cell as a monitoring period of the DCI;
[0265] When at least one of the DTX and the DRX of all the second cells of the terminal is activated, determining that both the inactive period and the active period of the DRX of the terminal are monitoring periods of the DCI;
[0266] When at least one of the DTX and the DRX of all the second cells of the terminal is not activated, determining the DTX activation period of the DRX of the terminal as the DCI monitoring period.
[0267] When not all second cells have at least one of DTX and DRX activated, it means that there is a second cell that can provide communication services to the terminal in a timely manner. Therefore, the activation period of the first cell DTX or the activation period of the terminal's DRX can be used as the DCI monitoring period. Otherwise, the activation period and the inactivation period of the first cell DTX, or the inactivation period and the activation period of the terminal's DRX can be used as the DCI monitoring period.
[0268] In some embodiments, the terminal monitors the DCI during a determined monitoring period.
[0269] In some embodiments, the terminal monitors the group-common DCI during a determined monitoring period.
[0270] In some embodiments, the terminal monitors DCI 2-9 during a determined monitoring period.

[0287] Solution 1.1: Based on the DTX / DRX activation state of a cell, determine whether to monitor DCI2-9 during the C-DRX inactive period.
[0288] For monitoring of DCI 2-9, the terminal will only monitor DCI 2-9 on one cell, and the network side will use RRC dedicated signaling to set the search space of DCI 2-9 on a certain cell.
[0289] The terminal does not wish to monitor DCI 2-9 on more than one cell in the cell group.
[0290] If the cell DTX and / or cell DRX of the cell configured with DCI 2-9 is in an activated state, the terminal needs to monitor DCI 2-9 during the C-DRX inactive period. In other words, the terminal needs to monitor DCI 2-9 during both the C-DRX active period and the C-DRX inactive period.
[0291] If the cell DTX and / or cell DRX of the cell configured with DCI 2-9 is in an inactive state, it is only necessary to monitor DCI 2-9 during the C-DRX active period.
[0292] DCI 2-9 is scrambled based on the NES RNTI configured on the network side.
[0293] Solution 1.2: Determine whether to monitor DCI 2-9 during the terminal C-DRX inactive period based on the DTX / DRX activation status of all serving cells.
[0294] The terminal will only monitor DCI 2-9 on one cell.
[0295] The network device (ie, the network side) will use RRC dedicated signaling to set the search space of DCI2-9 to a certain cell.
[0296] If the terminal has at least one cell with cell DTX and / or cell DRX deactivated (i.e., in an inactive state), at least one cell of the terminal is not configured with cell DTX / DRX, and the secondary cell that is not configured with cell DTX / DRX is in an active state, and the cell behavior is non-dormancy behavior, then regardless of the state of the cell DTX and / or cell DRX of the cell configured with DCI2-9 (inactive state, active state), it is only necessary to monitor DCI2-9 during the terminal C-DRX activation period. Otherwise, it is also necessary to follow the constraints in solution 1.1, or the terminal needs to monitor DCI2-9 during the terminal C-DRX inactive period. That is, it is necessary to monitor DCI2-9 during both the active period and the inactive period of the terminal C-DRX.
[0297] DCI 2-9 is scrambled based on the NES RNTI configured on the network side.
[0298] Solution 1.3: If all cells configured with cell DTX / DRX are in an active state, the terminal needs to monitor DCI 2-9 even during the terminal C-DRX inactive period. That is, the terminal needs to monitor DCI 2-9 during both the active and inactive periods of C-DRX. If all cells configured with cell DTX / DRX are in an inactive state, the terminal only needs to monitor DCI 2-9 during the active period of C-DRX. DCI 2-9 is scrambled based on the NES RNTI configured on the network side.
[0299] Solution 2.1: Determine whether to monitor DCI2-9 during the terminal cell DTX inactive period based on the DTX / DRX activation status of a cell
[0300] For monitoring of DCI 2-9, the terminal will only monitor DCI 2-9 on one cell. The network side will use RRC dedicated signaling to set the search space of DCI 2-9 on a certain cell.
[0301] If the cell DTX and / or cell DRX of the cell configured with DCI2-9 is in an activated state, the terminal needs to monitor DCI2-9 during the cell DTX inactive period (that is, it needs to monitor DCI2-9 in both active and inactive periods);
[0302] If the cell DTX and / or cell DRX of the cell configured with DCI 2-9 is in an inactive state, it is only necessary to monitor DCI 2-9 during the cell DTX active period.
[0303] DCI 2-9 is scrambled based on the NES RNTI configured on the network side. Note that the NES RNTI here is the cell DTRX-RANTI mentioned above.
[0304] Solution 2.2: Determine whether to monitor DCI2-9 during the cell DTX inactive period based on the DTX / DRX activation status of all serving cells
[0305] For monitoring of DCI 2-9, the terminal will monitor DCI 2-9 in only one cell. The network side will use RRC dedicated signaling to set the search space of DCI 2-9 to a certain cell.
[0306] If the terminal has at least one cell in which cell DTX and / or cell DRX is in an inactive state or no cell DTX / DRX is configured, and the cell is in an active state and not in dormancy, then regardless of the state of cell DTX and / or cell DRX of the cell configured with DCI 2-9 (which may include activation or deactivation), it only needs to monitor DCI 2-9 during the cell DTX activation period. Otherwise, it is also necessary to comply with the constraints in solution 1.1, or the terminal needs to monitor DCI 2-9 during both the cell DTX inactive period and the active period.
[0307] DCI 2-9 is scrambled based on the NES RNTI configured on the network side.
[0308] Solution 2.3:
[0309] If the cell DTX / DRX of all cells configured with cell DTX / DRX is in the activated state, the terminal needs to monitor DCI2-9 during the cell DTX inactive period (that is, it needs to monitor DCI2-9 during both active and inactive periods);
[0310] If the cell DTX / DRX of all cells configured with cell DTX / DRX is in an inactive state, it is only necessary to monitor DCI 2-9 during the cell DTX active period.
[0311] The DCI 2-9 is scrambled based on the NES RNTI configured on the network side.
