With the advent of internet of things (Internet of Things, IOT) technology, more and more devices that have not previously been provided with communication functions, such as, but not limited to, home appliances, vehicles, tool devices, service devices, and service facilities, began to obtain wireless communication functions by configuring a wireless communication unit so that the wireless communication network can be accessed and remote control can be accepted. Such devices are also included in the category of wireless communication devices because they are equipped with a wireless communication unit and have a wireless communication function. As an example, the Terminal device may include a Mobile cellular telephone, a cordless telephone, a Mobile Terminal (MT), a Mobile station, a Mobile device, a wireless Terminal, a handheld device, a client, a subscription station, a portable subscription station, an internet node, a communicator, a desktop computer, a laptop computer, a notebook computer, a tablet computer, a Personal communication system device, a Personal navigation device, a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), a wireless data card, a wireless Modem (Modulator demodulator, modem), a positioning device, a radio broadcast receiver, an electronic book device, a gaming device, an internet of things (Internet of Things, ioT) device, an in-vehicle device, an aircraft, a Virtual Reality (VR) device, an augmented Reality (Augmented Reality, AR) device, a wearable device (e.g., a smartwatch, etc.), a Terminal device in a 5G network or any of the evolved public land Mobile networks (Public Land Mobile Network, PLMN), other devices available for communication, or any combination of the above.

The term "network node" or "network device" as used in this disclosure is an entity or node that may be used for communication with a terminal device, e.g. an access network device. The access network device may be an apparatus deployed in a radio access network to provide wireless communication functionality for mobile terminals, and may be, for example, a radio access network (Radio Access Network, RAN) network device. The access network device may include various types of base stations. The base station is used for providing wireless access service for the terminal equipment. Specifically, each base station corresponds to a service coverage area, and terminal devices entering the service coverage area can communicate with the base station through wireless signals, so as to receive wireless access services provided by the base station. There may be an overlap between service coverage areas of base stations, and a terminal device in the overlapping area may receive wireless signals from multiple base stations, so that multiple base stations may serve the terminal device at the same time. Depending on the size of the service coverage area provided, the access network device may include Macro base stations providing Macro cells (Macro cells), micro base stations providing micro cells (Pico cells), pico base stations providing Pico cells, and Femto base stations providing Femto cells (Femto cells). The access network devices may also include various forms of relay stations, access points, remote Radio units (Remote Radio Unit, RRU), radio Heads (RH), remote Radio heads (Remote Radio Head, RRH), and so on. In systems employing different radio access technologies, the names of access network devices may vary, e.g., in long term evolution (Long Term Evolution, LTE) networks referred to as evolved nodebs (enbs or enodebs), in 3G networks as Nodebs (NB), in 5G networks as G nodebs (gNB) or NR nodebs (NR NB), etc. In some scenarios, the access network device may contain a Centralized Unit (CU) and/or a Distributed Unit (DU). The CUs and DUs may be placed in different places, for example: DU is far-pulled, placed in the area of high traffic, CU is placed in the central machine room. Or the CU and DU may be placed in the same room. The CU and DU may also be different components under one shelf. For convenience of description, in the subsequent embodiments of the present disclosure, the above devices for providing wireless communication functions for mobile terminals are collectively referred to as network devices, and embodiments of the present disclosure are not specifically limited.

When the terminal is in a CONNECTED state (RRC CONNECTED), one main task is to monitor the PDCCH, and the DCI may be used to carry information such as signaling or uplink and downlink data scheduling. And when the PDCCH is detected, time-frequency tracking of the local area, BM (Beam Management) measurement and reporting of the local area and CSI (CHANNEL STATE Indicator) measurement and reporting of the local area are required. The time-frequency tracking can enable the terminal and the base station to keep the synchronization of uplink and downlink timing, frequency offset and sampling, so that the terminal can correctly receive downlink signals and send uplink signals. The BM measurement and reporting in this area means that the terminal measures the sending beam of the base station and reports the measurement result to the base station, which is helpful for the base station to determine the service sending beam of the terminal and improve the quality of downlink receiving signals. The measurement and reporting of the CSI in this area refers to that the terminal measures the downlink channel linked with the base station and reports the measurement result to the base station, which helps the base station determine the downlink scheduling parameters (such as CQI CHANNEL Quality Indicator/PMI Precoding Matrix Indicator/RI Rank Indicator).

The time-frequency tracking of the present zone may be performed based on SSB (Synchronization Signal Block ), TRS (Tracking Reference Signal), where SSB is composed of time domain symbols where synchronization signal (PSS ((Primary Synchronization Signal) primary synchronization signal)/SSS ((Secondary Synchronization Signal) secondary synchronization signal)) and PBCH (Physical Broadcast Channel ) channels are located, so as to facilitate initial camping of UE. BM measurements (or L1-RSRP (REFERENCE SIGNAL RECEIVED Power) reference signal received Power) measurements for the region, L1-RSRP measurement for beam management, may be made based on SSB, CSI-RS. CSI measurements for the local region may be made based on CSI-RSs. The SSB period can take on the value 5/10/20/40/80/160ms, the FR1 is at most 8 SSBs, the FR2 is at most 64 SSBs, and each SSB occupies 4 symbols. The CSI-RS period can take a value of 4 slots to 640 slots. Up to 64 CSI-RS for CSI resources may be allocated, each of which occupies 1 to 4 symbols. Up to 64 CSI-RS resources for L1-RSRP measurements may be allocated, each of which occupies 1 symbol. The TRS period can take the value 10/20/40/80ms, and is provided with 4 TRS resources at most, and each resource occupies 1 symbol. Symbols between resources are also received because of the frequency offset that needs to be estimated and the phase change that occurs with respect to the symbols.

As described above, in the conventional scheme, when performing the above-described operations of time-frequency synchronization, BM measurement, CSI measurement, etc., the terminal needs to receive signals on all downlink resources, which is disadvantageous from the viewpoint of saving power consumption by the terminal. In view of this, the embodiment of the application provides a technical scheme, which can achieve the purpose of saving the power consumption of the terminal. In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings.

As an example, the solution of the embodiment of the present application may be applied to a 5G system. In some embodiments, to determine that there is no downlink data scheduling, the terminal device 110 may specifically determine that DCI without any one of the following scrambling schedules PDSCH of the present carrier: a cell radio network temporary identity (C-RNTI) and a configured scheduling-radio network temporary identity (CS-RNTI).

It should be noted that the 4G and 5G systems are merely examples of communication systems to which the present disclosure is applicable, and the scheme of the embodiment of the present application may be applied to systems other than the 4G and 5G systems.

In some embodiments, the step of skipping the reception of another part of the signal may specifically be skipping the reception of a synchronization signal block or a reference signal of a preset proportion of a plurality of synchronization signal blocks or a plurality of reference signals. For example a synchronization signal block or a reference signal skipped by 50% of the signal period.

Based on some embodiments of the present application, the terminal device 110 may perform downlink SSB/TRS, SSB based L1-RSRP measurement, CSI-RS for L1-RSRP measurement, and CSI-RS for CSI pilot reception at an adaptive interval in the NR connected state, until the conditions are no longer satisfied. And may receive at downlink intervals with respect to one or more pilots. Downlink interval reception refers to a downlink periodic pilot configured for the network device 120 (e.g., base station), and the terminal device 110 does not receive the entire period of the pilot, but receives the pilot of some periods dynamically according to an interval pattern. The skipped part of the periodic pilot frequency does not need to be processed by a corresponding baseband, and even does not need to turn on the downlink RF (radio frequency) of a corresponding symbol, thereby achieving the purpose of saving power consumption. Further details are provided below by way of specific examples.

Example 1:

When the terminal device 110 is in the NR connected state and has no DRX (Discontinuous Reception ) configuration, if there is no downlink data scheduling in the duration of continuous T1 and the condition for receiving the downlink CSI-RS for CSI measurement interval is satisfied, the terminal device 110 dynamically receives the downlink CSI-RS for CSI pilot (i.e., CSI-RS for CSI) according to the interval pattern, so as to perform downlink CSI measurement until there is downlink data scheduling next time or the condition for receiving corresponding interval is no longer satisfied.

In some embodiments, one specific implementation of the terminal device 110 detecting no downlink data scheduling may be: when the terminal device 110 determines that there is no downlink data scheduling, the PDSCH of the present carrier is scheduled by DCI scrambled by any one of a cell radio network temporary identity (C-RNTI) and a configuration scheduling-radio network temporary identity (CS-RNTI). And if the DCI scrambled by the C-RNTI or the CS-RNTI is used for scheduling the PDSCH of the carrier, determining that downlink data scheduling exists.

In other embodiments, a specific implementation of the terminal device 110 detecting no downlink data scheduling may be: when the terminal device 110 determines that the DCI scrambled by any one of the C-RNTI and the semi-persistent scheduling radio network temporary identity (SPS-RNTI) schedules the PDSCH of the present carrier, that is, determines that there is no downlink data scheduling. And if the DCI scrambled by the C-RNTI or the SPS-RNTI is used for scheduling the PDSCH of the carrier, determining that downlink data scheduling exists.

In some embodiments, the downlink CSI measurement interval reception conditions may include: the terminal equipment 110 is in a non-high-speed rail, and the serving cell downlink CSI-RS for CSI resource configuration period < X1 (X1 is a preset parameter of the terminal equipment 110).

The T2 duration is an example of a time threshold of the time of no downlink data scheduling, and may specifically be a parameter preconfigured at the terminal device 110.
