As shown in fig. 1, the method provided by the embodiments 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. Wherein the user equipment 101 is configured to support carrier aggregation and is connectable to a plurality of carrier units of the network device 102, including one primary carrier unit and one or more secondary carrier units.
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 user equipment (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 terminal (mobile terminal), a wireless communication device, a user equipment agent, a user equipment, 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 103.
The user equipment 101 may be, among other things, a cellular phone, a cordless phone, a session initiation protocol (session initiation protocol, SIP) phone, a wireless local loop (wireless local loop, WLL) station, a Personal Digital Assistant (PDA) device, a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a user equipment in a future 5G network or a user equipment in a future evolved PLMN network, etc.
Network device 102 may be an access network device (or access network site). The access network device refers to a device that provides a network access function, such as a radio access network (radio access network, RAN) base station, and so on. The network device 103 may specifically include a Base Station (BS), or include a base station and a radio resource management device for controlling the base station, or the like. The network device 102 may also include relay stations (relay devices), access points, base stations in future 5G networks, base stations in future evolved PLMN networks, or NR base stations, etc. Network device 102 may be a wearable device or an in-vehicle device. The network device 102 may also be a communication chip with a communication module.
For example, network device 102 includes, but is not limited to: a next generation base station (gnodeB, gNB) in 5G, an evolved node B (eNB) in LTE system, a radio network controller (radio network controller, RNC), a Node B (NB) in WCDMA system, a radio controller under CRAN system, a base station controller (basestation controller, BSC), a base transceiver station (base transceiver station, BTS) in GSM system or CDMA system, a home base station (e.g., home evolved nodeB, or home node B, HNB), a baseband unit (BBU), a transmission point (TRANSMITTING AND RECEIVING point, TRP), a transmission point (TRANSMITTING POINT, TP), a mobile switching center, or the like.
Considering that the ue needs to receive a scheduling instruction sent by the network device, the scheduling instruction is used for scheduling a physical Downlink shared channel (Physical Downlink SHARED CHANNEL, PDSCH), and the PDSCH is used for carrying data from a transmission channel (Downlink SHARED CHANNEL, DSCH). When PDSCH is scheduled, a scheduling delay k0 is indicated, that is, a scheduling instruction is sent in a time slot n1, and the scheduled PDSCH is located in a time slot n1+k0.
Therefore, whether the PDSCH scheduled by the scheduling instruction is received by the user equipment during dormancy needs to be considered, and if the PDSCH scheduled by the scheduling instruction is not received, the normal downlink data reception of the user equipment is affected. Therefore, when the ue needs to sleep, if the PDSCH scheduled by the scheduling instruction is not received, the sleep needs to be performed after the PDSCH scheduled by the scheduling instruction is received.

An embodiment of the present disclosure provides a method for controlling dormancy, and fig. 2 is a flowchart illustrating a method for controlling dormancy according to an exemplary embodiment, and as shown in fig. 2, the method includes steps S201 to S202, specifically:
s201, the user equipment determines that dormancy is needed at a first moment.
In some possible embodiments, the manner in which the ue determines that dormancy is required is: and when receiving the instruction for indicating dormancy, which is sent by the network equipment, namely, the instruction for indicating dormancy, which is sent by the network equipment, is received by the user equipment at the first moment, determining that dormancy is needed at the first moment.
In some possible embodiments, the manner in which the ue determines that dormancy is required is: the setting timer in the user equipment meets the setting condition to trigger the user equipment to sleep, namely the setting timer in the user equipment meets the setting condition at the first moment to trigger the user equipment to sleep, and the user equipment is determined to need to sleep at the first moment.
S202, when the user equipment does not receive the PDSCH scheduled by the scheduling instruction at the first time, the user equipment starts to perform sleep after the second time, where the second time is the time domain end position of the PDSCH.
The time domain end position of the PDSCH is the time domain end position of the time domain resource of the PDSCH.
In some possible implementations, the scheduling instruction is downlink control information (Downlink Control Information, DCI), and the PDSCH is one PDSCH scheduled by the DCI. The second time is the time domain end position of the PDSCH.
In some possible embodiments, the scheduling instruction is DCI, and the PDSCH is a plurality of PDSCH scheduled by the DCI. The second time is a time domain end position of a last PDSCH of the plurality of PDSCH.
In an example, the scheduling instruction in S202 refers to: one DCI before the first time that is closest to the first time. In S202, the ue does not receive the PDSCH scheduled by the scheduling instruction at the first time instant: the user equipment receives the DCI and then reaches the first time, and the PDSCH scheduled by the DCI is not received yet.
In another example, scheduling instruction scheduling in S202 refers to: the X most recent DCIs before the first time. Wherein X is 2,3, 4 or other integer value. In S202, the ue does not receive the PDSCH scheduled by the scheduling instruction at the first time instant: the user equipment sequentially receives the X pieces of DCI and then reaches the first time, and at this time, PDSCH scheduled by one or more pieces of DCI in the X pieces of DCI has not been received yet.
In some possible embodiments, the sleep is performed after the second time, including: and starting to execute dormancy in the next time slot of the time slot where the second time is located.
In some possible embodiments, the sleep is performed after the second time, including: and starting to execute dormancy in an N time slot after the time slot where the second time is located. Where N may have a value of 2, or 3, or other values. The value of N is protocol-agreed or network device-configured.
In some possible embodiments, between S201 and S202 further comprises: and monitoring a physical downlink control channel (Physical Downlink Control Channel, PDCCH) between the first time and the second time, so that if the network equipment has emergent service coming suddenly and needs to be sent to the user equipment between the first time and the second time, downlink data transmission can be continuously scheduled, and downlink data can be scheduled without waiting until the user equipment finishes dormancy.
In some possible embodiments, between S201 and S202 further comprises: and not monitoring DCI for scheduling uplink data or downlink data between the first time and the second time. For example, DCI for scheduling uplink data or downlink data is DCI0-0, DCI0-1, DCI0-2, DCI1-0, DCI1-1 or DCI1-2. Because the user equipment determines that dormancy is needed, the user equipment can not receive downlink transmission or send uplink transmission in a subsequent period of time, so that monitoring of DCI for downlink scheduling or uplink scheduling in a corresponding search space is not needed, the energy consumption of the user equipment can be saved, and the power saving of the user equipment is facilitated.
In some possible embodiments, between S201 and S202 further comprises: and monitoring the multicast DCI between the first time and the second time. For example: at least one of DCI 2-0, DCI 2-1, DCI 2-2, DCI 2-3, DCI 2-4 and DCI2-5 is monitored between the first time and the second time.
The above DCIs are all DCIs for non-scheduled data, and receiving these DCIs can be used to assist in the transmission of PDSCH/PUSCH that has been scheduled. For example, DCI 2-0 indicates SFI (slot format indicator), so that the user equipment can accurately determine that the user equipment can be used for uplink/downlink transmission, and for example, DCI 2-1 indicates PI (Preemption indication), which is used to indicate which time-frequency positions of the user equipment are unavailable for demodulation, so as to optimize the demodulation effect of the user equipment on the PDSCH. The DCI 2-2/2-3 is used for indicating power control information of data to be transmitted. DCI 2-4 is used to instruct a UE to terminate certain uplink transmissions to avoid affecting the transmission of emergency services of other user equipments. DCI 2-5 is used to indicate the computing resources available to the user equipment.
In an example, the terminal listens to DCI 2-1 between the first time and the second time, and the preemption indication (Pre-emption Indication, PI) is carried in DCI 2-1 to assist the user equipment in PDSCH demodulation.
In the embodiment of the disclosure, the first time and the second time refer to time domain positions, where the time domain positions may be represented by time slots or OFDM symbols, for example, the first time refers to the jth slot in the ith subframe, and for example, the first time refers to the nth symbol in the mth slot.
In the embodiment of the disclosure, whether the PDSCH scheduled by the scheduling instruction is received or not is considered when the user equipment needs to sleep, and if the PDSCH scheduled by the scheduling instruction is not received when the user equipment needs to sleep, the sleep is performed after the PDSCH scheduled by the scheduling instruction is received, so that the energy saving of the user equipment can be ensured without influencing the data transmission, the data can be normally received while the energy is saved, and the processing performance of the user equipment is improved.
