Description

Information indication method, terminal, network device, communication system and storage medium Technical Field

The present disclosure relates to the field of communication technology, and in particular to an information indication method, a terminal, a network device, a communication system and a storage medium.

Background Art

In the field of communication technology, a low-power wake-up signal (LP WUS, Low Power Wake Up Signal) is introduced. The terminal uses a separate low-power receiver (LP-WUR, Low Power Wake Up Radio) to receive the LP WUS signal. The terminal needs to use the main transceiver to process downlink and uplink data normally. If the terminal receives the LP WUS signal to indicate wake-up, the main transceiver will be turned on to receive and process downlink signals. If the WUS signal is not received, or the WUS signal indicates not to wake up, the terminal will keep the main transceiver in sleep mode.

The embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, the fourth generation mobile communication system (4G), the fifth 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 ... The present invention relates to wireless communication systems such as LTE, Wi-Fi (X), 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) network, Device to Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle to Everything (V2X), systems using other communication methods, and next-generation systems expanded based on them.

In some embodiments, the sensitivity of the LP WUR is lower than that of the main receiver. For example, the main receiver has a receiver sensitivity of -110 dB, while the receiver sensitivity of the LP WUR is -80 dB. Therefore, the coverage of the signal for the low power receiver may not be as good as the existing NR SSB.

In some embodiments, for a terminal in a radio resource control (RRC) connection state, when the main transceiver is dormant, LP WUR is used. When the network wants to wake up the terminal, the network sends LP WUS to the terminal to wake up the terminal. Therefore, the network side can clearly know when the terminal wakes up the main transceiver.

In some embodiments, a main receiver of a terminal in an RRC connected state measures and reports channel state information (CSI).

In some embodiments, for a terminal that is in an RRC connected state and in a master transceiver sleep state and/or an LP WUR listening state, since the master transceiver does not schedule data, frequent CSI reporting does not make much sense, and causes the master transceiver to frequently wake up for CSI reporting, resulting in energy waste of the terminal.

FIG2a is an interactive schematic diagram of an information indication method according to an embodiment of the present disclosure. As shown in FIG2a, the present disclosure embodiment relates to an information indication method, which is used in a communication system 100, and the method includes:

Step S2101: The network device sends first information to the terminal.

In some embodiments, the terminal receives first information sent by the network device.

In some embodiments, the terminal being in a dormant state may be that the main transceiver of the terminal is in a dormant state, and the low-power receiver of the terminal may be in an operating state. Here, the power consumption of the main transceiver may be greater than the power consumption of the low-power receiver.

In some embodiments, the reference signal is a channel state information reference signal (CSI-RS, CSI Reference Signal).

In some embodiments, the measurement report is a periodically reported measurement report or a semi-continuously reported measurement report.

In some embodiments, the terminal is in an RRC connected state, and at least one of the at least two different reporting periods is used for reporting measurement reports of reference signals when the terminal is in a sleep state and/or a low power consumption LP wake-up wireless WUR listening state.

In some embodiments, the reporting period includes a first reporting period and a second reporting period, and the second reporting period is used for reporting the measurement report when the terminal is in a sleep state and/or an LP WUR listening state. After receiving the first information, the terminal can report the measurement report when the terminal is in a sleep state and/or an LP WUR listening state based on the second reporting period. It should be noted that in this embodiment, there is no need to receive the second information in step S2101, and the terminal can select the second reporting period to directly report the measurement report when the terminal is in a sleep state and/or an LP WUR listening state.

In some embodiments, after receiving the first information, the terminal cannot determine which of the at least two different reporting periods indicated by the first information to use to report the measurement report when the terminal is in a sleep state and/or an LP WUR listening state. At this time, further instructions from the network device are required, please refer to step S2102.

Step S2102: The network device sends second information to the terminal.

In some embodiments, the terminal receives second information sent by the network device.

In some embodiments, the second information indicates a third reporting period among the at least two different reporting periods.

In some embodiments, the third reporting period is used for reporting the measurement report when the terminal is in a sleep state and/or a LP WUR listening state.

In some embodiments, the network device sends the second information to the terminal via a second signaling. Exemplarily, the second signaling may be a MAC CE signaling or a downlink control information (DCI, Download Control Information), which is not limited here.

In some embodiments, the second signaling is an activation signaling indicating activation of the LP WUR listening state.

In some embodiments, the second signaling is an LP WUS signal used to wake up the terminal.

In some embodiments, after receiving the first information, the terminal receives second information indicating a third reporting period among the at least two different reporting periods. The terminal reports the measurement report when the terminal is in a sleep state and/or an LP WUR listening state based on the third reporting period.

In some embodiments, the term "information" can be interchangeably with terms such as "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", and "data".

As shown in FIG5a, the present disclosure embodiment relates to an information indication method, which is used in a communication system 100, and the method includes one of the following steps:

Step S5101: The network device sends first information to the terminal;

In some embodiments, the first information indicates: at least two different reporting periods; at least one of the at least two different reporting periods is used for measurement reports of reference signals reported when the terminal is in a sleep state and/or a low power consumption LP wake-up wireless WUR listening state.

The optional implementation of step S5101 can refer to the optional implementation of step S2101 in FIG. 2a and other related parts of the embodiment involved in FIG. 2a, which will not be described in detail here.

In some embodiments, the above method may include the methods of the above-mentioned communication system side, terminal side, network device side, etc., which will not be repeated here.

In order to better understand the embodiments of the present disclosure, the technical solution of the present disclosure is further described below through an exemplary embodiment:

In some embodiments, for a terminal in RRC connected state and in master transceiver sleep/LP WUR listening state, the CSI reporting period should be sparser. This avoids energy waste caused by frequent wake-up of the master transceiver.

In some embodiments, the present disclosure provides a method 1:

The base station configures CSI reports (reports) with two different reporting periods (the first reporting period and the second reporting period) through high-level signaling. When the terminal is in the main transceiver sleep state or LP WUR monitoring state, the CSI report of the terminal will apply the second reporting period.

Exemplarily, the second reporting period is longer than the first reporting period.

In some embodiments, the present disclosure provides a second method:

The base station configures CSI reports (reports) with multiple different (number greater than or equal to 2) reporting periods through high-level signaling. The base station indicates which reporting period should be used when the terminal is in the main transceiver sleep/LP WUR monitoring state through the second signaling.

In some embodiments, the second signaling is different from the high-level configuration signaling. It can be MAC CE or DCI, for example, it can be an activation instruction for indicating activation of LP WUS listening state to indicate which reporting cycle should be used when the terminal is in the main transceiver sleep/LP WUR listening state.

In some embodiments, the LP WUS signal can also be used to dynamically indicate the CSI report cycle that the terminal should use while the terminal is in the LP WUS listening state. (Note that in addition to carrying whether to wake up the terminal, this LP WUS signal also carries instructions to instruct the terminal to change the CSI report cycle).

In some embodiments, the above two methods can be used for periodic and semi-continuous CSI reporting scenarios.
