Description

Information processing method, device and terminal

Technical Field

The present disclosure relates to the field of terminal technologies, and in particular, to an information processing method, an information processing device, and a terminal.

Background

In a 5G NR (new radio access technology) V2X (internet of vehicles) system, direct communication is performed between terminals on a direct link (sidlink). Before the service data transmission, the time-frequency resource used by the through link data transmission needs to be determined first, and the main criterion for determining the time-frequency resource is to avoid collision between the time-frequency resources used by different terminals so as to avoid mutual interference. In NR V2X, there are two resource scheduling modes, the first is a Mode (Mode) 1 resource allocation Mode, in which a base station uniformly schedules time-frequency resources used in the through link communication between terminals, and the second is a Mode2 resource allocation Mode, in which a terminal autonomously selects time-frequency resources used in the through link communication between terminals without participation of the base station.

The NR-V2X Mode 2 adopts distributed resource scheduling, and as no base station is used for uniform scheduling, UE (terminal) needs to determine the resource occupation condition of other UE through a resource sensing mechanism, and performs resource selection according to a resource sensing result. Compared with a completely random resource selection mechanism, the resource utilization rate can be improved through a resource sensing mechanism, the collision probability is reduced, and the system performance is improved.

However, in the prior art, the resource sensing process is performed continuously, that is, the terminal needs to sense continuously even though the terminal does not transmit data. The power consumption by continuous resource awareness is acceptable if the terminals involved in the through-link communication are all cars, but in the through-link communication system, there are pedestrian terminals (PUEs) or other portable mobile terminals that are sensitive to power consumption in addition to car terminals. For a pedestrian terminal (PUE), due to limited battery power of the PUE, continuous resource sensing can cause the battery power of the PUE to be rapidly exhausted, which affects the user experience and usability of the PUE participating in the through link communication.

The following first describes what the scheme provided in the embodiments of the present application relates to.

The NR-V2X direct link Mode2 resource allocation step comprises:

(1) Resource perception: resource awareness refers to that a terminal determines whether a resource is used by other terminals according to RSRP (reference signal received power) strength of a received signal on the resource. In the resource sensing process, different characteristics of periodic service and aperiodic service in a mixed service scene in NR V2X application and influence of service types on a resource sensing result need to be considered. Meanwhile, proper resource sensing configuration is required to be carried out according to the time-frequency resource granularity, the resource pool setting and other information in the physical channel. The resource sensing window refers to a time window for sensing resources by the terminal.

(2) And (3) resource elimination: the main purpose of the resource elimination is to eliminate resources which are not used for resource selection in a resource selection window according to a perceived result, such as eliminating time-frequency resources which are occupied by a terminal for receiving data (NR V2X terminal carries out data receiving and transmitting in a half duplex mode, and half duplex means that the terminal cannot receive and transmit data at the same time), so as to form a candidate resource set, reduce the probability of resource collision and improve the reliability.

(3) And (3) resource selection: the resource selection mechanism is to select a suitable transmission time-frequency resource for a service packet TB (transport block) to be transmitted in a candidate resource set, and needs to consider the priority, time delay, service packet size and transmission reliability requirements of the service to perform resource selection. The resource selection window refers to a time window in which the terminal performs resource selection.

And 2, NR-V2X Mode 2 adopts distributed resource scheduling, and as no base station is used for uniform scheduling, the UE needs to determine the resource occupation condition of other UEs through a resource sensing mechanism, and performs resource selection according to a resource sensing result. Compared with a completely random resource selection mechanism, the resource utilization rate can be improved through a resource sensing mechanism, the collision probability is reduced, and the system performance is improved.

When the service arrives, the terminal receives the data packet in the resource sensing window and decodes SCI (through link control information), the resources which fall in the resource selection window and have RSRP greater than the RSRP threshold value need to be removed, the rest resources are candidate resources, and then the resources required for through link transmission are randomly selected from the candidate resources with the minimum 20% of the RSSI or directly selected from all the candidate resources. Wherein the length of the resource selection window may be configured as the maximum period of traffic.

3. Before data transmission on the direct link, the terminal firstly carries out resource sensing and carries out resource selection according to the result of the resource sensing, and the mechanism can avoid collision to a certain extent. Currently, as shown in fig. 2, in order to obtain a result of resource sensing as accurate as possible, the terminal needs to continuously perform resource sensing, but this also brings about a significant increase in power consumption of the terminal.

Based on the above, the embodiments of the present application provide an information processing method, an information processing device, and a terminal, so as to solve the problem of high power consumption in the resource sensing scheme in the prior art.

The method, the device and the terminal are based on the same application conception, and because the principle of solving the problems by the method, the device and the terminal is similar, the implementation of the method, the device and the terminal can be mutually referred, and the repetition is not repeated.

The information processing method provided in the embodiment of the present application is applied to a first terminal, as shown in fig. 3, and includes:

Wherein FR1 can be in the range of 410MHz to 7125MHz, and FR2 can be in the range of 24250MHz to 52600MHz.

The following specifically exemplifies the schemes provided in the embodiments of the present application.

Example 1 (sequence design 1 of the first energy saving signal S-WUS):

the scheme provides a method for transmitting a first energy-saving signal S-WUS based on a sequence, which is applicable to a straight-through link, comprising the following steps of: the first terminal is instructed to wake up or sleep in the through link communication using a sequence based through link first power saving signal S-WUS. The awakening means that the first terminal starts to monitor the PSCCH, starts to perform resource sensing, starts to perform resource selection and the like; the dormant state means that the first terminal stops at least one operation of monitoring the PSCCH, stopping resource sensing, stopping resource selection, and the like.

The sequence of the first energy saving signal S-WUS can be a first sequence as follows:

d _S-WUS (n)＝[1-2x ₀ ((n+m ₀ )mod 132)][1-2x ₁ ((n+m ₁ )mod 132)]；

wherein:

x ₀ (i+7)＝(x ₀ (i+4)+x ₀ (i))mod 2；

x ₁ (i+7)＝(x ₁ (i+1)+x ₁ (i))mod 2；

and:

Specifically, the first sequence is a Gold sequence, the sequence length is 132, 11 RBs (resource blocks) are occupied, and each RB has 12 subcarriers. Each element in the first sequence occupies one subcarrier in the same OFDM symbol.

In the above first sequenceThe following is shown: />

Wherein:and->

In practice, the number of the cells to be processed,for representing the in-coverage SL-SSIDUsed to represent the out-of-coverage SL-SSID.

The present example employs such a first sequence design method by which a first sequence-based power saving signal S-WUS may be generated, thereby indicating that the first terminal is awake or dormant. The sequence generation is simpler and has lower complexity.

Example 2 (sequence design 2 for the first energy saving signal S-WUS):

the scheme provides a method for transmitting a first energy-saving signal S-WUS based on a sequence, which is applicable to a straight-through link, comprising the following steps of: the first terminal is instructed to wake up or sleep in the through link communication using a sequence based through link first power saving signal S-WUS. The awakening means that the first terminal monitors at least one operation such as PSCCH, starts to perform resource sensing, starts to perform resource selection and the like; the dormant state means that the first terminal stops at least one operation of monitoring the PSCCH, stopping resource sensing, stopping resource selection, and the like.

While the first energy saving signal S-WUS may take on a second sequence as follows:

S-WUS sequence d located in slot x=0, 1, …, M-1 _S-WUS (m) is defined as:

n＝0，1，…，131；

m′＝n+132x；

wherein: m is the number of slots in which the S-WUS signal is actually transmitted.Is a pseudo-random sequence, i=0, 1, …,2·132M-1.

In particular, pseudo-random sequencesDefined as Gold sequence c (n) of length 31. c (n) has a length M _PN Wherein n=0, 1, M _PN -1.c (n) is defined as follows:

c(n)＝(x ₁ (n+N _c )+x ₂ (n+N _c ))mod2；

x ₁ (n+31)＝(x ₁ (n+3)+x ₁ (n))mod2；

x ₂ (n+31)＝(x ₂ (n+3)+x ₂ (n+2)+x ₂ (n+1)+x ₂ (n))mod2；

wherein x is ₁ (n) represents the first m-sequence; x is x ₂ (n) represents the second m sequence; n represents; n (N) _c Representing initialization parameters, N _C =1600, the first m-sequence has an initialization value x ₁ (0)＝1,x ₁ (n) =0, n=1, 2,.; the initialization value of the second m-sequence is expressed as follows when the S-WUS signal starts to transmit:

wherein: n is n _f Is the subframe number associated with S-WUS, n _s Is the slot number associated with the S-WUS.

In the above second sequenceIs a physical layer direct link synchronous identification number, the value range is

Wherein:and->

The present example employs this second sequence design approach, by which a sequence-based first power-saving signal S-WUS may be generated, which may indicate that the first terminal is awake or dormant. The larger number of sequences is suitable for scenes with larger number of terminals.

Example 3 (first energy saving signal S-WUS indication):

Wherein (1) the first power saving signal S-WUS may be configured to indicate at least one of the following wake-up or sleep modes:

1) Terminal specific (UE-specific): one S-WUS signaling at a time wakes up or sleeps only one UE;

2) Cell-specific wake-up or sleep (Cell-specific): S-WUS signaling is used for waking up or dormancy of all UE in coverage in the same cell once;

3) Terminal Group specific (UE-Group-specific): one S-WUS signaling to wake up or sleep a group of UEs;

4) Through link identification number specific (SL-SSID-specific): one S-WUS signaling wakes up or sleeps all UEs with the same SL-SSID.

(2) Depending on the transmission type of the traffic channel, the first energy saving signal S-WUS may be configured as at least one of the following transmission methods:

If S-WUS signal transmission can only wake up or sleep one UE at a time, the S-WUS signal can be indicated in a UE-specific mode, the indication method has small indication granularity, and whether a single UE is waken up or sleep can be indicated, so that only a terminal with service requirements can be waken up, and the energy-saving effect is good.

The indication method of SL-SSID-specific can wake up all terminals with the same SL-SSID, namely all terminals in the same synchronous cluster, and the terminals start to monitor PSCCH or start to sense resources, the indication method has larger indication granularity, is suitable for broadcast service or multicast service, has smaller cost and is not easy to generate interference of S-WUS signals between the terminals.

In the example, the indication mode of the UE-specific or the UE-group-specific has better energy saving effect; the SL-SSID-specific or Cell-specific indication method has small cost and is not easy to generate interference of S-WUS signals between terminals.

Example 4 (first energy saving signal S-WUS of single-stage sequence or multistage sequence):

the first energy saving signal S-WUS in this embodiment may take the form of a single-stage sequence or a multi-stage sequence (in particular, a two-stage sequence).

Specifically, different sequence types can be selected according to scenes:

(1) When Cell-specific or SSID-specific: a single-stage sequence is adopted;

(2) When UE-specific or Group-specific: adopting a multi-stage sequence;

this has the advantage that in order to be able to provide more sequences available, typically hundreds of sequences (e.g. 256) can be supported when the S-WUS takes a single level of sequences; 256×256 sequences can be supported by adopting two-stage sequences, so that the wake-up or sleep mode of the UE-specific can be supported more effectively.

In this example, the S-WUS can obtain a larger sequence capacity by using a multi-level sequence, so that interference between S-WUS signals of the UE is avoided, and thus a wake-up or sleep mode of the UE-specific can be more effectively supported.

Example 5 (S-WUS power saving scheme 1: configure periodic SL DRX):

Specifically, when the periodical SL DRX is configured on the through link, the first power saving signal S-WUS instructs the first terminal to start at least one operation, such as PSCCH monitoring, resource sensing, and resource selection, in the SL DRX cycle associated with the S-WUS; or the first energy saving signal S-WUS indicates the first terminal to stop performing at least one operation such as PSCCH monitoring, resource sensing and resource selection; the operation on the "start" execution described above may specifically be the "start" execution operation at the start of the cycle.

Wherein, V2X (vehicle network) UEs in periodic SL DRX need to periodically wake up to monitor PSCCH or perform resource sensing or perform resource selection, so that most of the power consumption of the UE is consumed in periodically monitoring PSCCH and performing demodulation decoding of PSCCH or periodically performing resource sensing or resource selection, regardless of whether the UE really has a need for data reception or transmission. Meanwhile, in order for the UE to perform PSCCH demodulation, the UE needs to continuously perform signal processing, e.g., channel tracking, channel estimation, to ensure accuracy for PSCCH demodulation decoding.

However, the arrival of terminal data is typically bursty, non-periodic. Therefore, in this example, the first power saving signal S-WUS is used to indicate whether the UE needs to wake up (specifically, to indicate that the first terminal is awakened or dormant) for PSCCH monitoring or whether it needs to wake up for resource sensing or resource selection in the subsequent SL DRX cycle.

The above indication of the first energy saving signal S-WUS is performed by one of two methods: the method 1 is that the first energy saving signal S-WUS contains information for making the first terminal wake up or sleep, for example, the information indicates to wake up or sleep through different sequences; method 2 is to indicate to the first terminal that it is awake or dormant, i.e. whether a first power saving signal S-WUS is present or not: the first power saving signal S-WUS indicates that the first terminal is awake if it occurs and indicates that the first terminal is dormant if it does not occur.

Taking as an example, an indication method of whether the energy saving signal appears as the first energy saving signal S-WUS, where the first energy saving signal S-WUS is generally configured at a time domain position where a DRX cycle starts or ends, where the first terminal detects the first energy saving signal S-WUS, and if the first energy saving signal S-WUS is not detected, the UE does not wake up to monitor the PSCCH in the whole SL DRX cycle, or does not wake up to perform resource sensing or resource selection; otherwise, if the first power saving signal S-WUS is detected, the UE needs to wake up to monitor the PSCCH in the subsequent SL DRX cycle, or wake up to perform resource sensing or resource selection, so that the power consumption of the UE can be further reduced while ensuring the normal direct link communication of the UE.

As shown in fig. 5, the first terminal is configured with periodic SL DRX and has a DRX cycle shown in the figure. The dashed square represents that the first energy saving signal S-WUS is not present and the solid square represents that the first energy saving signal S-WUS is present. The dotted filling block represents that the first terminal is in a dormant state, the oblique line filling block represents that the first terminal is in an awakened state, and PSCCH monitoring, resource sensing or resource selecting operation is carried out in the awakened state. The first terminal will wake up only when the first power saving signal S-WUS is present, i.e. the first terminal detects a solid square; if the first power saving signal S-WUS does not occur, that is, the first terminal cannot detect the first power saving signal S-WUS at the position of the dotted square, the first terminal is not awakened, but continues to maintain the sleep state.

In this example, a first power saving signal S-WUS power saving scheme in case of configuring the periodic SL DRX is presented, with which it is possible to use the first power saving signal S-WUS to indicate whether the first terminal is awake or dormant, so that an effect of reducing power consumption of the first terminal can be achieved.

Example 6 (S-WUS power saving scheme 2: no SL DRX configured or aperiodic SL DRX configured):

When the SL DRX is not configured or only the aperiodic SL DRX is configured, the first power saving signal S-WUS instructs the first terminal to start at least one operation, such as PSCCH monitoring, resource sensing, and resource selection; or the first power saving signal S-WUS indicates that the first terminal stops at least one operation of PSCCH monitoring, resource sensing and resource selection.

When data arrives, the first energy saving signal S-WUS is used for triggering the UE to wake up, monitoring PSCCH or performing resource sensing or resource selection, and at the moment, the UE can be converted from a dormant state to a data receiving state, so that various operations can be started. If no first power saving signal S-WUS is detected, the UE may continue to sleep. At this time, since the first power saving signal S-WUS can be used to trigger the monitoring of data transmission and reception, the periodic DRX or the non-periodic DRX configured to completely match the traffic characteristics can be omitted.

The above indication of the first energy saving signal S-WUS is performed by one of two methods: the method 1 is that the first energy saving signal S-WUS contains information for making the first terminal wake up or sleep, for example, the information is represented by different sequences; method 2 is to indicate whether the first terminal is awake or dormant by the presence of the first power saving signal S-WUS, i.e.: the first power saving signal S-WUS indicates that the first terminal is awake if it occurs and indicates that the first terminal is dormant if it does not occur.

The present example takes as an example an indication of whether a power saving signal is present as the first power saving signal S-WUS, wherein the first power saving signal S-WUS is configured to occur non-periodically, and the first terminal detects the first power saving signal S-WUS at a time domain position where the first power saving signal S-WUS is present, and if the first power saving signal S-WUS is not detected, the UE will not wake up to monitor the PSCCH, or will not wake up for resource sensing or resource selection. Otherwise, if the first energy saving signal S-WUS is detected, the UE needs to wake up to monitor the PSCCH, or wake up to perform resource sensing or resource selection, so that the power consumption of the UE can be further reduced while ensuring the normal direct link communication of the UE.

As shown in fig. 6, the first terminal is not configured with SL DRX. The dashed boxes represent that the first energy saving signal S-WUS is absent and the solid boxes represent that S-WUS is present. The dotted filling block represents that the first terminal is in a dormant state, the oblique line filling block represents that the first terminal is in an awakened state, and PSCCH monitoring, resource sensing or resource selecting operation is carried out in the awakened state. The first terminal is awakened only when the S-WUS occurs, that is, when the first terminal detects the solid line square first power saving signal S-WUS; if the first power saving signal S-WUS does not occur, that is, the first terminal cannot detect the first power saving signal S-WUS at the position of the dotted square, the first terminal is not awakened, but continues to maintain the sleep state.

In this example, a first power saving signal S-WUS power saving scheme in the case of not configuring SL DRX or only configuring aperiodic SL DRX is presented, with which it is possible to use the first power saving signal S-WUS to indicate whether the first terminal is awake or dormant, so that an effect of reducing power consumption of the first terminal can be achieved.

Example 7 (beam transmission scheme of the first energy saving signal S-WUS):

in the scheme, the method comprises the following steps:

at FR1, the first energy saving signal S-WUS is transmitted in a symbol repetition manner, that is: the same S-WUS sequence is transmitted using at least two OFDM symbols.

At FR2, the first energy saving signal S-WUS is transmitted by means of beam scanning, i.e.: S-WUS sequences having different beam directions are transmitted using at least two OFDM symbols.

Different wave beam transmission modes are adopted in different working frequency bands, so that the method can adapt to the transmission characteristics of S-WUS signals in different frequency bands. In FR1, S-WUS is often transmitted by using a wide beam, and the same S-WUS sequence is repeatedly transmitted in multiple OFDM symbols, so that the first terminal can obtain a higher detection probability of the S-WUS signal sequence. In FR2, S-WUS is often transmitted by using a narrow beam, and different S-WUS beams are transmitted in different OFDM symbols by using a beam scanning manner, which may also enable the first terminal to obtain a higher S-WUS signal sequence detection probability.

By using the scheme, different beam transmission modes of the S-WUS can be flexibly selected according to different working frequency bands of the first terminal when the first terminal performs the direct link communication, so that the first terminal can obtain higher S-WUS signal sequence detection probability.

As can be seen from the foregoing, the embodiments of the present application provide a method for transmitting a sequence-based power saving signal (S-WUS, through link wake-up signal) applicable to a through link, where the sequence-based through link power saving signal is used to instruct a first terminal to wake up or sleep in through link communication. By using the method, the electricity consumption caused by the fact that the first terminal periodically monitors PSCCH (physical direct link control channel) or continuously senses resources is avoided, so that the first terminal can monitor PSCCH or sense resources or select resources according to service requirements, and the electricity consumption of the first terminal is reduced.

The embodiment of the present application further provides a terminal, where the terminal is a first terminal, as shown in fig. 7, and the terminal includes a memory 71, a transceiver 72, and a processor 73:

a memory 71 for storing a computer program; a transceiver 72 for transceiving data under the control of the processor 73; a processor 73 for reading the computer program in the memory 71 and performing the following operations:

awakening or dormancy according to the energy-saving signal;

the first operation includes at least one of:

monitoring a physical direct link control channel PSCCH;

performing resource sensing;

and selecting resources.
