The technical words related to the present application will be first described below.

1. Extended discontinuous reception (extended Discontinuous Reception, eDRX)

In the R17 RedCap project, the network may configure an extended discontinuous reception (Discontinuous Reception, DRX) cycle (i.e., eDRX) for use cases where DL reachability/latency requirements are relatively relaxed, which may significantly reduce UE power consumption during periods of sufficiently large packet inter-arrival times. Specifically, an extended DRX cycle is introduced for the RRC idle state (idle state, maximum 10485.76 seconds, i.e., about 3 hours) and the RRC inactive state (inactive state, maximum 10.24 seconds) as an optional feature of reduced capability (Reduced Capability, redCap) and non-RedCap UEs.

Fig. 2 shows a typical eDRX configuration. As shown in fig. 2, the UE listens to pages (paging) within a paging time window (paging time window, PTWs), each PTW may contain multiple paging cycles within one paging superframe (Hyper SFN,1 Hyper SFN containing 1024 SFNs). The PTW is periodic, i.e., the eDRX period, in units of Hyper SFN.

2. Low power consumption receiver

The 3GPP will start to introduce a low power consumption wake-up signal (LP WUR)/wake-up signal (WUS) into the Rel-18 mobile cellular system, please refer to fig. 3, wherein the basic working principle of the LP WUR is that the receiving end includes a first module and a second module. The first module is a main communication module for receiving and transmitting mobile communication data, and the second module is a low-power consumption wake-up receiving module for receiving the wake-up signal. The terminal starts a low-power consumption receiving module to monitor the LP-WUS in the energy-saving state, and closes the main communication module. When downlink data arrives, the network sends a wake-up signal to the terminal, and after the terminal monitors the wake-up signal through the low-power consumption receiving module, the terminal triggers the main communication module to turn on from off through a series of judgment, and at the moment, the low-power consumption receiving module enters into an off or sleep state from a working state. The low-power consumption receiving module can be continuously started or intermittently started, and can receive a low-power consumption wake-up signal when the low-power consumption receiving module is started.

In order to reduce the receiving activity of the terminal in the standby state, the Radio Frequency (RF) and baseband (MODEM) modules are actually turned off, so that the power consumption of communication reception is greatly reduced, and the communication reception can be realized by introducing a near zero power receiver into the receiving module of the terminal. This near "zero" power receiver does not require complex RF module signal detection (e.g., amplification, filtering, quantization, etc.) and MODEM signal processing, but relies on passive matched filtering and less power consuming signal processing.

On the base station side, a wake-up signal is triggered on demand (on-demand), so that a near zero power receiver can be activated to acquire an activated notification, and a series of processes inside the terminal are triggered, for example, a radio frequency transceiver module, a baseband processing module and the like are opened.

Such wake-up signals are typically relatively simple on-off keying signals (on-off keying) as shown in fig. 4, which the receiver can learn about the wake-up notice by simple energy detection, and possibly subsequent sequence detection and identification.

The possible sequence formats for the LP WUS are shown in fig. 5 and 6.

3. Rel-17inactive positioning

In order to save power consumption during positioning, the R17 phase standardizes positioning in an inactive state. The UE may perform positioning while in rrc_inactive.

Any uplink LCS or LPP message may be transmitted in rrc_inactive.

If the UE initiates data transmission using UL SDT, the network may send DL LCS, LPP, and RRC messages to the UE (e.g., configure sounding reference signals (Sounding Reference Signal, SRS) for UL positioning if supported).

The UE may also receive a positioning reference signal (Positioning Reference Signal, PRS) or transmit SRS in rrc_inactive.

Support for all New Radio (NR) positioning measurements and support for NR positioning methods, such as NR Enhanced Cell-ID, E-CID, downlink time difference of arrival (DL-TDOA), downlink angle of departure (DL-AOD), uplink angle of arrival (UL-AOA), UL-TDOA, multi-signal round trip time (Multi-RTT) and Radio access technology independent (ra-independent) positioning methods,

The LP-WUS signal in the examples of the present application is described in detail below.

In an embodiment of the present application, the format of the LP-WUS signal includes at least one of:

1) A sequence portion, optionally comprising a sequence;

2) Information bit (bit) portion.

Optionally, using the sequence portion and/or the information bits, at least one of the following is indicated:

indicating behavior in a specific RRC state;

indicating that the control signal/channel contains specific control information.

In an embodiment of the present application, optionally, the sequence includes at least one of:

1) A synchronization sequence, also known as a preamble sequence;

2) Indicating the information sequence.

Optionally, the indication information sequence is transmitted after the synchronization sequence.

Optionally, the information bit portion includes at least one of:

1) A control information bit section;

2) CRC scrambling of control information bits.

For a received LP-WUS signal that may use a low power receiver, possible signal/channel structures for the LP-WUS signal include: a sequence portion, an information bit portion, or a combination thereof. The sequence portion may be used for synchronization, or an information indication, the synchronized information sequence is also commonly referred to as a preamble. Usually, the preamble has a smaller format or sequence number, does not carry indication information, or has limited information capable of being indicated;

In order to enable the terminal to receive the LP-WUS signal using a low power receiver, the LP-WUS signal/channel is typically characterized by, for example, modulating the signal using binary On-Off Keying (OOK) or amplitude-shift Keying (ASK), or further using simple coding methods such as Manchester, pulse coding (Pulse interval encoding, PIE), FM0, miller, walsh coding, etc. to form a combination of signal amplitudes. That is, the information is transmitted by using the amplitude information or the combination of the amplitude information, and the terminal only needs to demodulate the control information by judging the amplitude information or the combination of the amplitude information.

In order to further carry the indication information (e.g. the first indication information described above), the indication information sequence may be further transmitted after the preamble, or the indication information sequence may be transmitted uncoded or encoded. A block diagram of a channel format potentially suitable for use in a low power receiver is shown in figure 9.

One way is to indicate the use of the control signal/channel by a preamble sequence, and the terminal performs the indication information in the control signal/channel only if a specific preamble is detected. The disadvantage is that the preamble is usually used for synchronization, and too much indication information may reduce synchronization accuracy or increase false alarm probability.

Or the first indication information is indicated by the indication information sequence, the sending end indicates different information by different sequences, and the receiving end determines the content indicated in the indication channel according to the different information sequences, so that the terminal needs to perform blind detection in a plurality of sequences to determine the content indicated by the control command. The indication information sequence may be preceded by a preamble sequence for synchronization, and after the synchronization is completed, the terminal determines the content of the first indication information based on the indication information sequence, in which case a further different use can be indicated than indicated by the preamble sequence.

For methods using different preamble sequences, or indicating information sequences indicating usage, it is contemplated to use different sequences of the same length, different lengths of the same sequence, or different sequences and different lengths.

In the above method, if the preamble or the indication sequence part is used for information type or use indication, when the terminal detects that the sequence finds a target sequence which is not the terminal, the terminal can discard to further detect the subsequent data part, thereby saving power consumption.

Alternatively, the use of the information bit indicates the purpose of the control command after the preamble or the indication information bit. The method using the information bit indication has stronger flexibility or expandability. The different usage control signals can be distinguished in the following way:

1) The use of different control commands with different sequence lengths, for example, the use 1 when the control command length is L1; the use control command length is L2, which is the use 2.

2) An information specific field indication is used, for example, a specific X bits in a control command is used for the indication.

3) Indicated using the CRC of the control information bit.

Scrambling, for example using RNTI, e.g. C-RNTI for LP-WUS indicating connected terminals; the P-RNTI (paging RNTI) or other RNTI is used for scrambling for the idle state or sleep state terminals.

Alternatively, the CRC is scrambled using a predefined scrambling sequence, e.g. using <0, … 0>, <0, …,1> indicates that different control commands are distinguished.

Alternatively, different CRC generator polynomials are used to distinguish, for example, the CRC generator polynomial for the control command for use 1 is x15+x11+x10+x7+x4+x2+x+1; the CRC generator polynomial for the control command of use 2 is x15+x13+x9+x8+x6+x3+x+1;

preferably, the above methods may be combined, and when there are many indication information of different uses, the preamble, the indication information sequence, or the bits of the control information field jointly indicate the use of the control signal/channel.

In a network deployment, different nodes may all send such signals for different functions. However, for a particular terminal, only one or a limited number of functions are required or configured by the network to transmit using such control channels/signals. For example, for a particular function (e.g., a positioning function), the network configures a particular sequence (which may be a preamble sequence, or an indication information sequence) in the control signal/channel, or a particular information bit(s), or a particular CRC. If the terminal detects a specific sequence, or specific information bit, or specific CRC, the terminal considers the channel/signal as the signal/channel for the terminal, and can further analyze bit(s) information transmitted in the signal/channel.

For example, the sequence part in the channel contains two candidate sequences, sequence 0 is used to indicate that the sequence is used to indicate that the channel is used to indicate terminals in paging idle state or inactive state, and sequence 1 is used to indicate that the channel is used to indicate positioning functions. And under the condition that the terminal detects the matched sequence according to the current state, the terminal analyzes the subsequent information bits, wherein the information bits may further indicate specific parameters of terminal behaviors or functions in an RRC idle state or a non-activated state respectively.

For example, the first two bits in the information bit are headers, and when a header is '0,0', the indication PDCCH skip is indicated (the base station may send a PDCCH skip indication to let ue in a connected state skip a PDCCH snoop for a period of time), and a header is '0,1' indicates that the paging terminal is indicated. If the terminal in the connection state only configures the function of PDCCH skip, and does not need to monitor paging, the terminal only analyzes the subsequent field under the condition that the header bits are '0,0', and the field may include some specific parameters of PDCCH skip, for example, the time period of skip, etc. Similarly, a terminal configured with paging in idle or inactive state will only parse the subsequent field if the header is '0, 1'.

In consideration of limited power consumption of low-power consumption reception, the analysis can be performed in the main receiver, namely, only if the terminal detects the matched sequence, the information bit(s) and the CRC, the main receiver can be opened for analysis, so that the power consumption can be further reduced. When the signals detected by the terminals are not matched, the terminals discard or ignore the signals and the channels.

The network may transmit indication information for different terminals or different purposes in the same control signal or channel, for example, the x … y bit in the control information bit indicates that ue#1 is paged, and the p … q in the control information bit indicates that system information update is performed; or the x … y bit in the control information bit indicates that the idle state or non-active state UE (or group) is paged, and the p … q bit in the control information indicates that the RRC Connected UE#2 performs PDCCH skip. These locations may be predefined or network configured.
