The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

As shown in FIG. 1 , the method provided in the embodiment of the present disclosure may be applied to a wireless communication system 100 , which may include a user device 101 and a network device 102 , and the number of the devices included is not limited.

It should be understood that the above wireless communication system 100 can be applied to both low-frequency scenarios and high-frequency scenarios. The application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, worldwide interoperability for microwave access (WiMAX) communication system, cloud radio access network (CRAN) system, future fifth-generation (5G) system, new radio (NR) communication system or future evolved public land mobile network (PLMN) system, etc.

The user equipment 101 shown above may be a terminal, an access user equipment, a user equipment unit, a user equipment station, a mobile station (MS), a remote station, a remote user equipment, a mobile user equipment (mobile terminal), a wireless communication device, a user equipment agent, etc. The user equipment 101 may have a wireless transceiver function, and it may communicate with one or more network devices of one or more communication systems (such as wireless communication) and receive network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 102.

Among them, the user equipment 101 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, a vehicle-mounted device, a wearable device, a user device in a future 5G network, or a user device in a future evolved PLMN network, etc.

For example, the network device 102 may be an access network device (or access network point).

The network device 102 may also be a communication chip with a communication module.

Consider that when the network device performs DTX and/or DRX, it may affect the signal transmission and reception of the UE. For example, for a UE in the Radio Resource Control (RRC) idle state or the RRC inactive state, during the period of performing DTX, the network device may no longer send some signals (such as paging information, system information, etc.) that are periodically sent when DTX is not performed, and during the period of performing DRX, it may no longer receive some signals (such as Physical Random Access Channel (PRACH)) that are periodically detected when DRX is not performed.

In order to prevent the transmission and reception of the UE from being affected by the DTX and/or DRX performed by the network device, it is necessary to know whether the network device is performing DTX and/or DRX in different time periods.

The present disclosure provides a method for transmitting indication information, and FIG2 is a flow chart showing a method for transmitting indication information according to an exemplary embodiment. As shown in FIG2 , the method includes S201 to S204:

S201, the network device sends instruction information.

The indication information is used to indicate at least one of the following in the serving cell: DTX information, DRX information.

In some possible implementations, the DTX information includes the effective duration of DTX, and the DRX information includes the effective duration of DRX.

A UE in an RRC non-connected state receives indication information sent by a network device, and can obtain at least one of the following in the serving cell in which it is located: DTX information and DRX information.

In some possible implementations, when the indication information sent by the network device indicates DTX information of a serving cell, it means that the network device performs DTX from the effective moment, that is, the network device is in a DTX state (which may be referred to as a first state).

When the indication information sent by the network device indicates the DRX information of a serving cell, it means that the network device starts to perform DRX from the effective time, that is, the network device is in the DRX state (which may be called the second state).

When the indication information sent by the network device indicates the DTX information and DRX information of a serving cell, it means that the network device executes DRX from the effective moment, that is, the network device is in the DTX and DRX state (which may be called the third state).

In some possible implementations, the network device sends the indication information by sending DCI, where the DCI includes the indication information. After receiving the DCI, the UE can obtain the indication information included in the DCI.

Optionally, a broadcast DCI is sent in a cell so that all UEs in the cell can obtain the indication information.

In one example, a network device sends a paging DCI, and a UE receives the paging DCI, wherein the paging DCI includes the indication information. The paging DCI may be DCI 1-0, which is scrambled by a paging Radio Network Temporary Identity (P-RNTI).

In another example, the network device sends a paging early indication (PEI) DCI, and the UE receives the PEI DCI, where the PEI PCI includes the indication information. The PEI DCI may be DCI 2-7, which is scrambled by the PEI-RNTI.

In another example, the network device sends a PEI DCI on the PEI search space, the UE receives a PEI DCI on the PEI search space, the UE has been configured with the PEI search space and the UE supports PEI monitoring, and the PEI DCI includes the indication information.

In another example, the network device sends paging DCI in the search space of paging DCI, the UE receives paging DCI in the search space of paging DCI, the UE is not configured with PEI search space or the UE does not support PEI monitoring, and the paging DCI includes the indication information.

In another example, the network device sends a PEI DCI on the PEI search space and sends a paging DCI on the search space of the paging DCI, the UE has been configured with the PEI search space and the UE supports PEI monitoring, the PEI DCI includes the indication information, and the paging DCI includes the indication information.

In another example, the network device sends the paging DCI in the search space of the paging DCI, the UE is not configured with the PEI search space or the UE does not support PEI monitoring, and the paging DCI includes the indication information.

In some possible implementations, the indication information takes effect at a set time domain location.

In one example, when the DCI sent by the network device is a paging DCI, the paging DCI includes the indication information, and the indication information takes effect from the starting time domain position of the first paging frame (PF) of the paging cycle (paging cycle) to which the paging occasion (paging Occasion, PO) where the paging DCI is located belongs.

In another example, when the DCI sent by the network device is PEI DCI, the PEI DCI includes the indication information, and the indication information takes effect from the starting time domain position of the first paging frame (PF) of the paging cycle (paging cycle) to which the paging occasion (paging Occasion, PO) corresponding to the PEI DCI belongs.

In some possible implementations, the indication information occupies the first information field in the DCI.

Optionally, the first information domain is agreed upon by the protocol or set in advance by the network device.

Optionally, the first information field may be one of the default information fields in the DCI, or may be a new information field added in the DCI for carrying the indication information.

In one example, the first information field occupies 4 bits. The network device can use 4 bits to indicate 16 DTX durations, can use 4 bits to indicate 16 DRX durations, and can also use 4 bits to indicate m DTX durations and n DRX durations, where m and n are both positive integers, and the sum of m and n is 16.

In some possible implementations, the indication information includes an information field for indicating DTX information and an information field for indicating DRX information.

In one example, the information field for indicating DTX information occupies 2 bits, and the information field for indicating DRX information occupies 2 bits. The network device can use the information field for indicating DTX information to indicate 4 types of DTX durations, and use the information field for indicating DRX information to indicate 4 types of DRX durations.

In some possible implementations, the DCI includes a second information field, where the second information field is used to indicate whether the indication information indicates DTX information or DRX information.

In one example, the second information field occupies 1 bit.

When the value of the second information field is 1, it indicates that the indication information in the DCI indicates DTX information; when the value of the second information field is 0, it indicates that the indication information in the DCI indicates DRX information.

or,

When the value of the second information field is 1, it indicates that the indication information in the DCI indicates DRX information; when the value of the second information field is 0, it indicates that the indication information in the DCI indicates DTX information.

In some possible implementations, the network device does not send a tracking reference signal (TRS) for the non-connected state during the effective period of DTX, which means that the effective period of the TRS will end after the effective period of DTX. The UE does not monitor the TRS for the non-connected state during the effective period of DTX.

S202, the UE sends and receives data according to the indication information.

In some possible implementations, when the UE determines, based on the indication information, that the network device starts to perform DTX at the effective moment, the UE receives downlink data during the DTX-on period and does not receive downlink data during the DTX-off period.

When the UE determines, based on the indication information, that the network device starts to perform DRX at the effective time, the UE sends uplink data during the DRX-on period and does not send uplink data during the DTX-off period.

The UE determines according to the indication information that when the network device starts to execute DTX and DRX at the effective time, it receives downlink data in the DTX-on period, does not receive downlink data in the DTX-off period, and sends uplink data in the DTX-on period, and does not send uplink data in the DTX-off period.

In the disclosed embodiment, the network device sends indication information, and uses the indication information to indicate the DTX information and/or DRX information in the service cell, so that the UE can accurately know the status of the network device executing DTX and/or DRX, and accordingly send and receive data according to the status, thereby ensuring the normal transmission of data on the UE side when the network device executes DTX and/or DRX.

Based on the same concept as the above method embodiment, the embodiment of the present disclosure also provides a communication device, which may have the function of the UE in the above method embodiment and is used to execute the steps performed by the UE provided in the above embodiment. The function can be implemented by hardware, or by software or hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the above functions.

In a possible implementation manner, the transceiver module 301 is further configured not to monitor the tracking reference signal for the non-connected state during the DTX effective period.

In some possible implementations, the indication information in the paging DCI is effective at a first time domain position, where the first time domain position is a starting time domain position of a first paging frame of a paging cycle to which the paging occasion where the paging DCI is located belongs.

In some possible implementations, the indication information in the PEI DCI takes effect at a second time domain position, and the second time domain position is the starting time domain position of the first paging frame of the paging cycle to which the paging opportunity corresponding to the PEI DCI belongs.

In some possible implementations, the DTX information includes the effective duration of DTX, and the DRX information includes the effective duration of DRX.

As shown in Figure 6, the device 600 includes a memory 601, a processor 602, a transceiver component 603, and a power supply component 606. Among them, the memory 601 is coupled to the processor 602, and can be used to store the programs and data necessary for the communication device 600 to implement various functions. The processor 602 is configured to support the communication device 600 to perform the corresponding functions in the above method, which can be implemented by calling the program stored in the memory 601. The transceiver component 603 can be a wireless transceiver, which can be used to support the communication device 600 to receive signaling and/or data through a wireless air interface, and send signaling and/or data. The transceiver component 603 may also be referred to as a transceiver unit or a communication unit. The transceiver component 603 may include a radio frequency component 604 and one or more antennas 605, wherein the radio frequency component 604 may be a remote radio unit (RRU), which may be specifically used for transmission of radio frequency signals and conversion of radio frequency signals into baseband signals, and the one or more antennas 605 may be specifically used for radiation and reception of radio frequency signals.

When the communication device 600 needs to send data, the processor 602 can perform baseband processing on the data to be sent, and then output the baseband signal to the RF unit. The RF unit performs RF processing on the baseband signal and then sends the RF signal in the form of electromagnetic waves through the antenna. When data is sent to the communication device 600, the RF unit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor 602. The processor 602 converts the baseband signal into data and processes the data.
