Description

Information processing method and device and terminal
Technical Field
The present application relates to the field of terminal technologies, and in particular, to an information processing method, an information processing apparatus, and a terminal.
Background
In a 5G NR (new radio access technology) V2X (internet of vehicles) system, terminals communicate directly with each other over a direct link (Sidelink). Before service data transmission, time-frequency resources used for data transmission of a through link need to be determined, and the main criterion for determining the time-frequency resources is to avoid collision among 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 the base station uniformly schedules time-frequency resources used in direct link communication between terminals, and the second is a Mode2 resource allocation Mode in which the terminal autonomously selects time-frequency resources used in direct link communication between terminals without the participation of the base station.
The NR-V2X Mode2 adopts distributed resource scheduling, and because no base station uniformly schedules, the UE (terminal) needs to determine the resource occupation condition of other UE through a resource sensing mechanism and select resources according to the resource sensing result. Compared with a completely random resource selection mechanism, the resource utilization rate can be improved through the 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 all the time, that is, even if the terminal has no data to transmit, the terminal needs to continuously sense. The power consumption due to the continuous resource awareness is also acceptable if the terminals participating in the through-link communication are all cars, but there are pedestrian terminals (PUEs) or other portable mobile terminals that are sensitive to power consumption in addition to car terminals in the through-link communication system. For a pedestrian terminal (PUE), since the battery power of the PUE is limited, the battery power of the PUE is rapidly exhausted due to continuous resource perception, and the user experience and the availability of the PUE participating in the direct link communication are affected.

The following first introduces the contents related to the scheme provided in the embodiments of the present application.
The step of NR-V2X through link Mode2 resource allocation comprises:
(1) resource perception: resource sensing refers to a terminal determining whether a resource is used by other terminals according to the 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 the NR V2X application need to be considered, and the influence of the service type on the resource sensing result. Meanwhile, appropriate resource sensing configuration is required to be performed according to information such as time-frequency resource granularity and resource pool setting in the physical channel. The resource perception window refers to a time window for the terminal to perceive resources.
(2) And (3) resource exclusion: the main purpose of resource exclusion is to exclude resources that are not available for resource selection in the resource selection window according to the sensing result, for example, excluding time-frequency resources that the terminal needs to occupy to receive data (the NR V2X terminal performs data transceiving in a half-duplex manner, where half-duplex means that the terminal cannot simultaneously transceive data), forming a candidate resource set, reducing the resource collision probability, and improving reliability.
(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 the resource selection needs to be performed in consideration of the priority, the time delay, the size of the service packet, and the transmission reliability requirements of the service. The resource selection window refers to a time window for the terminal to select resources.
And 2, the NR-V2X Mode2 adopts distributed resource scheduling, and because no base station uniformly schedules, the UE needs to determine the resource occupation condition of other UE through a resource sensing mechanism and select resources according to a resource sensing result. Compared with a completely random resource selection mechanism, the resource utilization rate can be improved through the 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 (direct link control information), the resources which fall in the resource selection window and have RSRP larger than the RSRP threshold value need to be excluded, the remaining resources are candidate resources, and then the resources required by direct link transmission are randomly selected from the 20% of the candidate resources with the minimum RSSI or are directly randomly selected from all the candidate resources. Wherein the length of the resource selection window can be configured as the maximum period of the traffic.
3. Before data is sent on the direct link, the terminal firstly conducts resource sensing and conducts resource selection according to the result of the resource sensing, and the mechanism can avoid collision to a certain extent. At present, as shown in fig. 2, in order to obtain the most accurate result of resource sensing, the terminal needs to continuously perform resource sensing, but this would also cause a significant increase in power consumption of the terminal.
Based on the above, embodiments of the present application provide an information processing method, an information processing apparatus, and a terminal, so as to solve the problem of large power consumption of a resource sensing scheme in the prior art.
The method, the device and the terminal are based on the same application concept, and because the principles of solving the problems of the method, the device and the terminal are similar, the implementation of the method, the device and the terminal can be mutually referred, and repeated parts are not repeated.
The information processing method provided in the embodiment of the present application is applied to a first terminal, and as shown in fig. 3, includes:
step 31: receiving a sequence-based power save signal;
step 32: awakening or sleeping according to the energy-saving signal;
wherein the waking refers to starting to perform a first operation in the through link communication;
the being dormant refers to stopping performing a first operation in a through link communication;
the first operation comprises at least one of:
monitoring a physical direct link control channel (PSCCH);
carrying out resource perception;
and selecting resources.

Wherein FR1 can be 410 MHz-7125 MHz, and FR2 can be 24250 MHz-52600 MHz.
The following specifically exemplifies the scheme provided in the embodiments of the present application.

The example adopts such a design method of the second sequence, and the sequence-based first power saving signal S-WUS can be generated according to the method, so as to indicate that the first terminal is awakened or sleeps. The sequence generation quantity is large, and the method is suitable for scenes with large quantity of terminals.
Example 3 (first power save signal S-WUS indication mode):
the scheme provides a sequence-based first energy-saving signal S-WUS sending method suitable for a direct link, which comprises the following steps: a sequence-based through-link first power save signal S-WUS is employed to indicate that the first terminal is awake or dormant in through-link communications. The above-mentioned awakening means that the first terminal starts to monitor the PSCCH, starts to perform resource sensing, and starts to perform at least one operation such as resource selection; the dormant mode refers to at least one operation of stopping monitoring the PSCCH, stopping performing resource sensing, stopping performing resource selection, and the like of the first terminal.
Wherein (1) the first power save signal S-WUS may be configured to indicate at least one of a wake-up or sleep mode:
1) terminal-specific (UE-specific): only one UE is awakened or dormant for one S-WUS signal transmission;
2) cell-specific wake-up or sleep (Cell-specific): one S-WUS signal transmission awakens or sleeps all UE in coverage in the same cell;
3) terminal Group-specific (UE-Group-specific): waking up or sleeping a group of UEs for one S-WUS signal transmission;
4) straight-through link identification number specific (SL-SSID-specific): one S-WUS signaling wakes up or sleeps all UEs with the same SL-SSID.
(2) According to the transmission type of the traffic channel, the first power save signal S-WUS may be configured with at least one of the following transmission methods:
1) when the transmission type is unicast (Unitcast): adopting a UE-specific S-WUS signal transmission mode;
2) when the transmission type is broadcast (Boardcast): adopting an S-WUS signal transmission mode of Cell-specific or SL-SSID-specific;
3) when the transmission type is multicast (Groupcast): and adopting an S-WUS signal transmission mode of UE-group-specific or SL-SSID-specific.
If only one UE can be awakened or dormant in one S-WUS signal transmission, the S-WUS signal can be indicated in a UE-specific mode, the indication granularity of the indication method is small, whether the single UE is awakened or dormant can be indicated, and therefore only a terminal with service requirements can be awakened, and the energy-saving effect is good.
According to the SL-SSID-specific indication method, all terminals with the same SL-SSID (service set identifier-service set identifier) can be awakened by one S-WUS signal, namely all terminals in the same synchronization cluster, and the terminals start to monitor PSCCH (secure physical control channel) or start to sense resources.
In the example, the indication mode of the UE-specific or UE-group-specific has better energy-saving effect; the SL-SSID-specific or Cell-specific indication method has low overhead and is not easy to generate interference of S-WUS signals between terminals.
Example 4 (first power save signal S-WUS for single stage sequence or multi-stage sequence):
the first power saving signal S-WUS in this embodiment may be in a single-stage sequence or a multi-stage sequence (specifically, a two-stage sequence).
Specifically, different sequence types may be selected according to the scene:
(1) when Cell-specific or SSID-specific: a single stage sequence is adopted;
(2) when UE-specific or Group-specific: a multi-stage sequence is adopted;
this has the advantage that in order to be able to provide more available sequences, typically hundreds of sequences (e.g. 256) can be supported when the S-WUS assumes a single level sequence; and 256 × 256 sequences can be supported by adopting the two-stage sequence, so that the UE-specific awakening or sleeping mode can be more effectively supported.
In the example, the S-WUS can obtain larger sequence capacity by adopting a multi-stage sequence, and avoids interference between S-WUS signals of the UE, so that the UE-specific awakening or sleeping mode can be supported more effectively.
Example 5(S-WUS Power saving scheme 1: configure periodic SL DRX):
the scheme provides a sequence-based first energy-saving signal S-WUS sending method suitable for a direct link, which comprises the following steps: a sequence-based through-link first power save signal S-WUS is employed to indicate that the first terminal is awake or dormant in through-link communications. The above-mentioned awakening means that the first terminal starts to monitor the PSCCH, starts to perform resource sensing, and starts to perform at least one operation such as resource selection; the dormant mode refers to at least one operation of stopping monitoring the PSCCH, stopping performing resource sensing, stopping performing resource selection, and the like of the first terminal.
Specifically, when a periodic SL DRX is configured on the direct link, the first energy-saving signal S-WUS instructs the first terminal to start at least one of PSCCH monitoring, resource sensing, resource selection, and the like 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 of PSCCH monitoring, resource sensing, resource selection and the like; the operation concerning the above-described "start" execution may specifically be "start" execution of the operation at the start of the cycle.
Among them, V2X (vehicle network) UE in the periodic SL DRX needs to periodically wake up to monitor the PSCCH or perform resource sensing or resource selection, so that most of the power consumption of the UE is consumed in periodically monitoring the PSCCH and performing demodulation decoding of the 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, such as channel tracking and channel estimation, to ensure accuracy of decoding for PSCCH demodulation.
However, the arrival of terminal data is typically bursty, aperiodic. 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 woken up or is asleep) for PSCCH monitoring in the subsequent SL DRX cycle, or whether the UE needs to wake up for resource sensing or resource selection.
The above indication of the first power save signal S-WUS is performed by one of two methods: method 1 is that the first power save signal S-WUS contains information to cause the first terminal to wake up or sleep, e.g. by a different sequence to indicate wake up or sleep; method 2 is to indicate the first terminal to be woken up or sleeping through whether the first power saving signal S-WUS appears, that is: the first power save signal S-WUS indicates that the first terminal is awake if present and that the first terminal is asleep if not present.
This example takes an indication method of whether a power saving signal appears as a first power saving signal S-WUS as an example, where the first power saving signal S-WUS is generally configured at a time domain position where a DRX cycle starts or ends, and at the time domain position, the first terminal detects the first power saving signal S-WUS, and if the first power saving signal S-WUS is not detected, the UE does not wake up any more to monitor a PSCCH within the entire SL DRX cycle or does not wake up any more to perform resource sensing or resource selection; otherwise, if the first energy-saving signal S-WUS is detected, the UE needs to wake up to perform PSCCH monitoring in a subsequent SL DRX cycle, or wake up to perform resource sensing or resource selection, so that the UE can be ensured to normally communicate through the link, and the power consumption of the UE can be further reduced.
As shown in fig. 5, the first terminal is configured with periodic SL DRX and has the DRX cycle shown in the figure. The dashed square indicates that the first power save signal S-WUS is not present, and the solid square indicates that the first power save signal S-WUS is present. The dotted filling box represents that the first terminal is in a dormant state, and the oblique filling box represents that the first terminal is in an awakened state, and performs PSCCH monitoring, resource sensing or resource selection operation in the awakened state. The first terminal is awakened only when the first energy-saving signal S-WUS appears, namely the first terminal detects the solid square; and if the first power saving signal S-WUS does not appear, namely the first terminal does not detect the first power saving signal S-WUS at the position of the dotted line block, the first terminal is not awakened and continues to keep the dormant state.
In this example, a first power saving signal S-WUS power saving scheme under the condition that the periodic SL DRX is configured is given, and with the scheme, whether the first terminal is awakened or dormant can be indicated by using the first power saving signal S-WUS, so that the effect of reducing the energy 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):
the scheme provides a sequence-based first energy-saving signal S-WUS sending method suitable for a direct link, which comprises the following steps: a sequence-based through-link first power save signal S-WUS is employed to indicate that the first terminal is awake or dormant in through-link communications. The above-mentioned awakening means that the first terminal starts to monitor the PSCCH, starts to perform resource sensing, and starts to perform at least one operation such as resource selection; the dormant mode refers to at least one operation of stopping monitoring the PSCCH, stopping performing resource sensing, stopping performing resource selection, and the like of the first terminal.
When the SL DRX is not configured or only the aperiodic SL DRX is configured, the first energy-saving signal S-WUS indicates the first terminal to start at least one operation of PSCCH monitoring, resource sensing, resource selection and the like; or the first energy-saving signal S-WUS instructs the first terminal to stop performing at least one of PSCCH monitoring, resource sensing and resource selection.
When data arrives, the first energy-saving signal S-WUS is used for triggering UE to wake up, monitoring PSCCH or carrying out resource sensing or resource selection, and at the moment, the UE can be switched from a dormant state to a data receiving state, so that various operations can be started. If no first power save signal S-WUS is detected, the UE may continue to sleep. At this time, since the triggering of the listening of the data transmission and reception can be completely performed by the first power saving signal S-WUS, it is possible to dispense with the configuration of the periodic DRX or the non-periodic DRX configured to completely match the traffic characteristics.
The above indication of the first power save signal S-WUS is performed by one of two methods: method 1 is that the first power saving signal S-WUS contains information to make the first terminal awake or sleep, e.g. by different sequences to indicate awake or sleep; method 2 is to indicate that the first terminal is awakened or sleeped by whether the first power saving signal S-WUS appears, that is: the first power save signal S-WUS indicates that the first terminal is awake if present and that the first terminal is asleep if not present.
The example takes an indication method of whether a power saving signal appears as a first power saving signal S-WUS as an example, wherein the first power saving signal S-WUS is configured to appear aperiodically, the first terminal detects the first power saving signal S-WUS at a time domain position where the first power saving signal S-WUS appears, and if the first power saving signal S-WUS is not detected, the UE will not wake up to monitor PSCCH or wake up to perform 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 normal direct link communication of the UE can be ensured, and meanwhile, the power consumption of the UE can be further reduced.
As shown in fig. 6, the first terminal is not configured with SL DRX. The dashed square indicates that the first power save signal S-WUS is not present and the solid square indicates that S-WUS is present. The dotted filling box represents that the first terminal is in a dormant state, and the oblique filling box represents that the first terminal is in an awakened state, and performs PSCCH monitoring, resource sensing or resource selection operation in the awakened state. The first terminal is awakened only when the S-WUS appears, namely the first terminal detects a first energy-saving signal S-WUS of a solid square; and if the first power saving signal S-WUS does not appear, namely the first terminal does not detect the first power saving signal S-WUS at the position of the dotted line block, the first terminal is not awakened and continues to keep the dormant state.
In this example, a first power saving signal S-WUS power saving scheme is given in the case where no SL DRX is configured or only aperiodic SL DRX is configured, and with this scheme, the first power saving signal S-WUS can be used to indicate whether the first terminal is awake or asleep, so that an effect of reducing power consumption of the first terminal can be achieved.
Example 7 (beam transmission mode of the first power save signal S-WUS):
in the scheme:
in FR1, the first power save signal S-WUS is transmitted with symbol repetition, i.e.: the same S-WUS sequence is transmitted using at least two OFDM symbols.
In FR2, the first power save signal S-WUS is transmitted in a beam scanning manner, namely: S-WUS sequences with different beam directions are transmitted using at least two OFDM symbols.
Different wave beam transmitting modes are adopted in different working frequency bands, and the method can adapt to the transmitting characteristics of S-WUS signals in different frequency bands. In FR1, the S-WUS often transmits using a wide beam, and the first terminal can obtain a high probability of detecting the S-WUS signal sequence by repeating the transmission of the same S-WUS sequence in a plurality of OFDM symbols. In FR2, the S-WUS usually uses narrow beams for transmission, and uses a beam scanning method to transmit different S-WUS beams in different OFDM symbols, so that the first terminal can obtain a higher S-WUS signal sequence detection probability.
By using the scheme, different S-WUS beam transmitting modes can be flexibly selected according to different working frequency bands of the first terminal during the direct link communication, so that the first terminal can obtain higher S-WUS signal sequence detection probability.
As can be seen from the above, the embodiment of the present application provides a sequence-based power saving signal (S-WUS, through link wake-up signal) sending method suitable for a through link, where the sequence-based through link power saving signal is used to indicate that a first terminal is woken up or sleeps in through link communication. By using the method, the power consumption caused by the first terminal periodically monitoring the PSCCH (physical direct link control channel) or continuously sensing the resources is avoided, so that the first terminal can perform PSCCH monitoring or resource sensing or resource selection according to the service requirement, and the power consumption of the first terminal is reduced.
