Description

Information processing method and communication device

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information processing method and a communication device.

Background

Sidelink (direct link or sidelink) terminals, typically vehicles supporting Sidelink technology, road Site Units (RSUs), handsets, etc., may communicate with other terminals on Sidelink.

The user may perform a Sidelink transmission (transmission or reception) based on a selected synchronization source (synchronization reference source), which may be a base station, a global satellite navigation system (Global Navigation SATELLITE SYSTEM, GNSS), a self-local clock generated timing, or a timing provided by other devices, or a timing also referred to as a synchronization reference (synchronization reference) or a timing reference (TIMING REFERENCE). Sidelink resources may be numbered based on Sidelink timing, at which point the frame Number of Sidelink is called a direct frame Number (DIRECT FRAME Number, DFN). The following scenarios may exist:

One scenario is that a base station on carrier 1 schedules Sidelink transmissions on carrier 2 for a user using the timing of the base station on carrier 2 as the Sidelink timing of its own Sidelink transmissions.

Another scenario is where a base station operating on carrier 1 schedules Sidelink transmissions on carrier 2 for a user using other timing on carrier 2, e.g., GNSS timing as Sidelink timing for own Sidelink transmissions. The Uu timing and Sidelink timing may not be aligned at this time.

In addition, the subcarrier spacing (SubCarrier Spacing, SCS) of the sidelink and the subcarrier spacing of Uu may also be different, and thus the timing accuracy is also different.

In the prior art, when at least one of the following conditions is satisfied, the base station and the terminal understand Sidelink resources and/or Uu resources differently, so that the base station cannot allocate appropriate PUCCH (Physical Uplink Control Channel )/PUSCH (Physical Uplink SHARED CHANNEL, physical Uplink shared channel) resources to the terminal:

Case 1: the synchronization reference adopted by the terminal is different from the timing of the base station; for example, the terminal uses GNSS timing and the base station does not have a GNSS antenna or is not aligned with the GNSS;

Case 2: the base stations of different operators (PLMN) schedule Sidelink on the same frequency band, and because the base stations of different operators may not be synchronized, if the users respectively adopt the timing of each base station to perform Sidelink transmission, the situation that communication cannot be performed is caused;

Case 3: for inter-RAT scheduling, the transition between different modules and signaling needs to take a certain time, so that even in the case of alignment of base station timing and Sidelink timing, a certain delay and uncertainty are caused to the scheduling.

All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

In embodiments of the invention, words such as "exemplary" or "such as" are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" or "e.g." in an embodiment should not be taken as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete fashion.

The first communication device provided by the embodiment of the invention can be a terminal or a control node; the second communication device may be a control node or a terminal. For example, when the first communication device is a terminal, the second communication device is a control node; or when the first communication device is a control node, the second communication device is a terminal.

The terminal may be a mobile phone, a tablet computer, a notebook computer, an Ultra-Mobile Personal Computer (UMPC), a netbook, a wearable device (Wearable Device), a vehicle-mounted device, or a Personal digital assistant (Personal DIGITAL ASSISTANT, PDA), etc. It should be noted that, in the embodiment of the present invention, the specific type of the terminal is not limited. The control node refers to a base station or some integrated access Backhaul nodes (IAB), in the sidelink, the control node may be a terminal, a Road Side Unit (RSU), the base station may be some other network facilities like the RSU or IAB, so some control nodes may have sidelink and Uu links at the same time; the base station may be a commonly used base station, an evolved node b (evolved node base station, eNB), a network side device in a 5G system (for example, a next generation base station (next generation node base station, gNB) or a transmitting and receiving point (transmission and reception point, TRP)) or a cell, etc.

The Uu transmission, uu SCS, uu link, uu resource means uplink and/or downlink transmission between the terminal and the base station, uplink SCS and/or downlink SCS between the terminal and the base station, uplink and/or downlink resource between the terminal and the base station, and/or downlink resource, etc.

As shown in fig. 1, an embodiment of the present invention provides an information processing method, applied to a first communication device, including:

The time of the terminal processing the signal;

The ability of the terminal to process signals.

It should be noted that, the timing information acquired by the terminal and the timing information reported by the terminal are not necessarily identical, and there may be a conversion process. For example, the timing offset acquired by the terminal is based on 15kHz, and the timing offset may be converted into 30kHz timing offset before the terminal reports the timing information. For another example, the timing offset acquired by the terminal is a non-integer, and the timing offset may be reported after the operation of rounding up or rounding down.

Optionally, in the case that the first communication device is a control node and the second communication device is a terminal, step 101 configures timing information for the control node and the terminal, where the timing information includes at least one of the following:

The cell may be on the carrier on which Sidelink transmissions are made or may be on another carrier, not specifically limited herein.

LTE SIDELINK terminal reports timing information to NR base station; alternatively, the timing information at this time is indicated in 15kHz (subcarrier spacing SCS);

NR SIDELINK terminal reports timing information to LTE base station; optionally, the timing information is indicated at this time at 15kHz or NR SIDELINK SCS.

Or in the case that the first communication device is a base station and the second communication device is a terminal, the terminal and the base station may be:

The NR base station configures timing information for LTE SIDELINK terminals; alternatively, the timing information is configured at this time in 15kHz (subcarrier spacing SCS);

For example, the timing may be at least one of the related information us, symbol, slot, subframe, ms, frame, second, such as DFN (DIRECT FRAME Number ) Number, sidelink slot Number, sidelink symbol Number.

For another example, the timing offset may be offset information of at least one of us, symbol, slot, subframe, ms, frame, second, such as at least one of frame level difference, slot level difference, symbol level difference, us level difference, ms level difference, second level difference; and/or at least one of frame number, slot number, symbol number, us number, ms number, second number.

As another alternative embodiment, in case the first communication device is a terminal, the method further comprises:

And/or the number of the groups of groups,

and allocating Sidelink resources and/or Uu resources to the terminal according to the timing information.

For example, sidelink resources include: the configuration Sidelink grants at least one of the resources (SL configured grant), PSCCH, PSSCH, PSFCH. For another example, uu resources include: at least one of PUCCH and PUSCH.

Alternatively, sidelink resources and/or Uu resources may be configured by the control node or acquired by the terminal itself, without specific limitation herein.

Note that, when the timing information includes a timing offset, the timing offset includes:

A valid value or an invalid value. Specifically, 0 is a valid value, in one implementation the specific meaning of the invalid value is that the first communication device cannot determine or acquire the timing offset, and in another implementation the specific meaning of the invalid value is that the first communication device cannot indicate the timing offset.

Scene 1: sidelink resources are allocated based on the control node timing (e.g., sidelink resources are allocated based on Uu slots), and the timing information contains a timing offset O. The terminal performs Sidelink transmissions based on the timing offset O.

For example, when the terminal receives Sidelink downlink control information DCI at Uu time n, the DCI schedules Sidelink to transmit, and the DCI indicates Sidelink to transmit at time n+y1, the terminal transmits Sidelink in the first Sidelink slots not earlier than n+y1+o.

Scene 2: uu resources are allocated based on Sidelink timing (e.g., uu resources are allocated based on Sidelink slots), where the timing information contains a timing offset O. The terminal performs Uu transmission based on the timing offset O.

For example, the control node schedules the terminal to perform PUCCH transmission after the y2 time passes after PSFCH of Sidelink time m, for example, feedback HARQ-ACK information of the sidelink to the control node through the PUCCH, and the terminal performs PUCCH transmission in a time slot that is not earlier than the first time of m+y2+o and can transmit the PUCCH.

Scene 3: the sidelink resource is allocated based on Sidelink timing, or the Uu resource is allocated based on control node timing, at this time, the timing information does not contain timing offset, or the timing information contains timing offset and the value of the timing offset is 0, or the timing information contains timing offset and the value of the timing offset is invalid. The invalid value may also be referred to as a special value or a meaningless value.

As an alternative embodiment, in the case that the first condition is satisfied and the first communication device is a terminal, the timing information does not include a timing offset or includes a timing offset in the timing information and the timing offset is an invalid value or 0;

or when the first condition is satisfied and the first communication device is a control node, the timing information includes a timing offset.

Wherein the first condition includes at least one of:

the terminal selects the timing of the control node as a synchronous reference;

the terminal selects the control node timing as Sidelink timing;

The control node obtains Sidelink timing;

the control node configures the synchronous reference of the terminal as the control node; for example, the control node configures the type of the synchronization reference of the terminal to be the control node, i.e. the synchronization reference of the terminal may be any base station; for another example, the control node configures the synchronization reference of the terminal as the current control node, i.e. the current base station or the serving base station;

the control node configures the synchronization reference of the terminal to be the control node of the same public land mobile network PLMN.

As another alternative embodiment, in the case where the second condition is satisfied and the first communication device is a terminal, the timing information includes a timing offset;

Or in the case that the second condition is satisfied and the first communication device is a control node, the timing offset is not included in the timing information or the timing offset is included in the timing information and is an invalid value or 0.

Wherein the second condition includes at least one of:

the control node schedules the terminal as cross access technology inter-RAT scheduling;

The terminal selects other devices except the control node as synchronous references; for example, the other devices are other network side devices and/or other terminals except the control node;

The terminal selects other device timing except the control node timing as Sidelink timing; for example, the other device timings are other terminal timings and/or GNSS timings than the control node; for another example, the other device timing is other network side device timing except the current control node or the serving base station, and/or other terminal timing, and/or GNSS timing;

the control node cannot acquire Sidelink timings;

The control node does not configure the synchronous reference of the terminal;

The terminal selects control nodes of other PLMNs as synchronous references;

The terminal selects the control node timing of the other PLMN as Sidelink timing.

When the control node is an LTE base station, the control node may schedule NR SIDELINK (this case is referred to as Inter-RAT SIDELINK scheduling) or LTE SIDELINK (this case is referred to as intra-RAT SIDELINK scheduling). When the control node is a 5G or later version of the base station, the control node may schedule NR SIDELINK (this case is referred to as intra-RAT SIDELINK scheduling) or LTE SIDELINK (this case is referred to as Inter-RAT SIDELINK scheduling).

In the case of Sidelink carriers or numerology (parameter set) with Sidelink timing, and numerology (parameter set) with Uu timing or Uu carrier, the timing information is indicated according to any one of the following subcarrier intervals:

sidelink subcarrier spacing and a minimum subcarrier spacing of Uu subcarrier spacing;

For example one, the base station instructs the terminal to report Sidelink a timing offset between the timing and the base station timing.

Optionally, the offset is derived by the user based on GNSS timing and acquired base station timing; for example, offset is the difference between GNSS timing and SFN (system frame number); the offset may also be preconfigured.

The base station in this example acquires this offset and can derive Sidelink timings of the terminals to ensure proper resource allocation.

For example two, the base station indicates Sidelink timing at which the user reported the terminal.

The base station in this example acquires Sidelink a timing to ensure proper resource allocation. For example, after the base station acquires the sidelink timing, the sidelink resource is allocated according to the sidelink timing.

Example three, the base station indicates the synchronization reference of the user reporting terminal

Assume that the terminal reports a synchronization reference as a GNSS.

In this example, the base station may search for the GNSS itself, and after determining that the GNSS timing is used by the user through the information reported by the user, the base station may derive the Sidelink timing of the user by determining the offset between the GNSS timing and the base station timing, so as to ensure appropriate resource allocation.

In example four, the base station instructs the terminal to report GNSS timing.

In this example the terminal acquires the GNSS timing, but at this point the terminal may or may not have selected GNSS as its own synchronization reference. The base station acquires the GNSS timing by reporting the terminal, so as to determine offset between the GNSS timing and the base station timing, and thus, the offset values offsetDFN of the reasonable direct frame number DFN and the system frame number SFN can be configured, and proper resource allocation is ensured.

Example five

Let Uu subcarrier spacing= Sidelink subcarrier spacing=30 kHz.

The timing information reported by the terminal at this point includes Sidelink timings and/or timing offsets, e.g., sidelink timings are the number of 30kHz slots, offset is the number of slots of the offset defined in terms of 30kHz subcarrier spacing.

Example six

Let Uu subcarrier spacing = 15kHz; sidelink subcarrier spacing = 30kHz.

At this time, the timing information packet Sidelink reported by the terminal is timed and/or the timing is shifted; wherein the timing information is expressed in terms of Uu subcarrier spacing 15kHz, for example, the number of corresponding slots of the sidelink timing is reinterpretated and reported in terms of 15kHz, the timing offset being the number of slots of the offset defined in terms of 15kHz subcarrier spacing.

Another example is where the timing information is represented in terms of Sidelink sub-carrier intervals of 30kHz, e.g. the sidelink timing is the number of slots defined in terms of 30kHz sub-carrier intervals, the timing offset is the number of slots of the offset defined in terms of 30kHz sub-carrier intervals.

Example seven, inter-RAT.

Assume that LTE subcarriers are 15kHz apart; NR subcarrier spacing=30 kHz.

Assuming that the terminal is LTE SIDELINK terminals, the base station is an NR base station, and the terminals report LTE SIDELINK timing information to the base station; further optionally the timing information is expressed in terms of 15kHz or 30 kHz.

Assuming that the terminal is NR SIDELINK terminals, the base station is an LTE base station, and the terminals report NR SIDELINK timing information to the base station; further optionally the timing information is expressed in terms of 15 kHz.

Eight example, a timing offset O exists between Sidelink timing and Uu timing.

Assuming that the downlink control information DCI schedules two transmissions and k=n=2, N being a period of PSFCH, K being a minimum interval between PSFCH and the corresponding physical side link shared channel PSSCH;

Sidelink subcarrier spacing = uplink subcarrier spacing = downlink subcarrier spacing;

assume offset o=0.5 sidelink slot=0.5 uplink slot.

The time slot corresponding to the base station timing y2=1 is time slot 1, and the time slot corresponding to the Sidelink timing y2=1 is time slot 1', as shown in fig. 3, it can be seen that the positions of time slot 1 and time slot 1' are different. The terminal may actually consider that PUCCH cannot be transmitted earlier than slot 1', and since PUCCH resources are Uu resources, PUCCH resources actually used for HARQ-ACK information feedback of sidelink should be:

An available Uu slot or UL slot overlapping with slot 1 'and not earlier than slot 1';

Or, not earlier than the last available Uu slot or UL slot of slot 1';

Or, uu time slots or UL time slots corresponding to T _{PSFCH_Uu}+2+ceil(0.5)＝T_{PSFCH_Uu} +3;

Or, not earlier than the last available UL slot of the Uu slot corresponding to T _{PSFCH_Uu}+2+ceil(0.5)＝T_{PSFCH_Uu} +3.

For example, PUCCH resources on slot 2 as shown in fig. 3. Let T _{PSFCH_Uu} be the start of the slot in which PSFCH is located in this example; then T _{PSFCH_Uu} +2 in fig. 3 corresponds to time slot 1 in fig. 3, T _{PSFCH_Uu} +3 corresponds to time slot 2 in fig. 3, and when T _{PSFCH_Uu} is defined as the end of the time slot in PSFCH, the adjustment (e.g., the backward shift) of the correspondence between the time slots corresponding to T _{PSFCH_Uu} +2 and T _{PSFCH_Uu} +3 will not be described.

In this example, after determining the timing and/or timing offset of the sidelink by the user reporting or other methods, the base station allocates PUCCH resources on the slot 2 for HARQ-ACK feedback of the user sidelink, and the terminal uses the PUCCH on the slot 2 for HARQ-ACK feedback of the sidelink.
