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

It should be appreciated that the above wireless communication system 100 is applicable to both low frequency and high frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long term evolution (long term evolution, LTE) systems, LTE frequency division duplex (frequency division duplex, FDD) systems, LTE time division duplex (time division duplex, TDD) systems, worldwide interoperability for microwave access (worldwide interoperability for micro WAVE ACCESS, wiMAX) communication systems, cloud radio access network (cloud radio access network, CRAN) systems, future fifth Generation (5 th-Generation, 5G) systems, new Radio (NR) communication systems, or future evolved public land mobile network (public land mobile network, PLMN) systems, etc.

The user equipment 101 shown above may be a terminal (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, or the like. The user device 101 may be provided with wireless transceiver functionality that is capable of communicating (e.g., wirelessly communicating) with one or more network devices of one or more communication systems and receiving network services provided by the network devices, including, but not limited to, the illustrated network device 102.

It is contemplated that when the network device performs DTX and/or DRX, signaling of the UE may be affected. For example: for UEs in a radio resource control (Radio Resource Control, RRC) idle state (idle) or RRC inactive state (inactive), the network device may not send some signals (e.g., paging information, system information, etc.) periodically sent when DTX is not performed during DTX execution, and may not receive some signals (e.g., physical Random access channel (Physical Random ACCESS CHANNEL, PRACH), etc.) periodically detected when DRX is not performed during DRX execution.

In order for the UE's transceiving to be unaffected by the network device performing DTX and/or DRX, it is necessary to know whether the network device is performing DTX and/or DRX in different periods.

An embodiment of the present disclosure provides a method for transmitting indication information, and fig. 2 is a flowchart illustrating a method for transmitting indication information according to an exemplary embodiment. As shown in fig. 2, the method includes S201 to S204:

s201, the network device transmits the indication information.

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

The UE in the RRC non-connected state receives the indication information sent by the network device, and may learn at least one of the following in the serving cell: DTX information, DRX information.

In some possible embodiments, when the indication information sent by the network device indicates DTX information of a serving cell, it indicates that the network device performs DTX from the time of validation, i.e. 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 indicates that the network device starts to perform DRX from the effective moment, that is, the network device is in a DRX state (which may be referred to as a second state).

When the indication information sent by the network device indicates DTX information and DRX information of a serving cell, it indicates that the network device starts to perform DRX from the time of validity, i.e. the network device is in DTX and DRX states (which may be referred to as a third state).

In some possible embodiments, the manner in which the network device sends the indication information is: and transmitting DCI, wherein the DCI comprises indication information. After receiving the DCI, the UE may learn the indication information included in the DCI.

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

In an example, the network device transmits paging DCI, and the UE receives the paging DCI, where the paging DCI includes the indication information. The paging DCI may be DCI 1-0, scrambled by a paging radio network temporary identity (paging Radio Network Temporary Identity, P-RNTI).

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

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

In another example, a network device sends paging DCI over a paging DCI search space, a UE receives paging DCI over a paging DCI search space, the UE is not configured with a PEI search space or the UE does not support PEI listening, the paging DCI includes the indication information.

In another example, a network device transmits PEI DCI on the PEI search space and transmits paging DCI on the search space of paging DCI, the UE having configured the PEI search space and the UE supporting PEI listening, the PEI DCI including the indication information, the paging DCI including the indication information.

In another example, a network device transmits paging DCI on a search space of paging DCI, the UE not configured with a PEI search space or the UE not supporting PEI listening, the paging DCI including the indication information.

In some possible embodiments, the indication information is validated at a set time domain location.

In an example, when the DCI transmitted by the network device is paging DCI, the paging DCI includes the indication information, where the indication information is validated from a start time domain position of a first paging frame (PAGING FRAME, PF) of a paging cycle (PAGING CYCLE) to which a paging occasion (paging Occasion, PO) where the paging DCI is located belongs.

In another example, when the DCI transmitted by the network device is PEI DCI, the PEI DCI includes the indication information, where the indication information takes effect from a start time domain position of a first paging frame (PAGING FRAME, PF) of a paging cycle (PAGING CYCLE) to which a paging occasion (paging Occasion, PO) corresponding to the PEI DCI belongs.

Optionally, the first information field is agreed with a protocol or set in advance by the network device.

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

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

In an 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 may indicate 4 DTX durations using an information field for indicating DTX information and 4 DRX durations using an information field for indicating DRX information.

In some possible embodiments, the DCI includes a second information field for indicating whether DTX information or DRX information is indicated in the indication information.

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

When the value of the second information field is 1, 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 alternatively

When the value of the second information field is 1, indicating 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 transmit tracking reference signals (TRACKING REFERENCE SIGNAL, TRS) for the unconnected state during DTX validation, i.e., indicating that the TRS validation period will terminate after DTX validation. The UE does not listen to the TRS for the non-connected state during DTX validation.

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

In some possible embodiments, when the UE determines that the network device starts to perform DTX at the effective time according to the indication information, the UE receives downlink data in a DTX-on period, and does not receive downlink data in a DTX-off period.

And the UE transmits uplink data in a DRX-on period and does not transmit the uplink data in a DTX-off period when determining that the network equipment starts executing the DRX at the effective moment according to the indication information.

And the UE determines that the network equipment receives downlink data in a DTX-on period and does not receive the downlink data in a DTX-off period when the network equipment starts to execute DTX and DRX at the effective moment according to the indication information, and transmits uplink data in the DRX-on period and does not transmit the uplink data in the DTX-off period.

In the embodiment of the disclosure, the network device sends the indication information, and the indication information is used for indicating the DTX information and/or the DRX information in the serving cell, so that the UE accurately knows the state of the network device for executing the DTX and/or the DRX, and correspondingly carries out data transceiving according to the state, thereby ensuring the normal transmission of data at the UE side when the network device executes the DTX and/or the DRX.
