Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable. The wireless communication system includes a terminal 11 and a network device 12. The terminal 11 may be a mobile phone, a tablet (Tablet Personal Computer), a Laptop (Laptop Computer) or a terminal-side Device called a notebook, a personal digital assistant (Personal Digital Assistant, PDA), a palm Computer, a netbook, an ultra-mobile personal Computer (ultra-mobile personal Computer, UMPC), a mobile internet appliance (Mobile Internet Device, MID), an augmented reality (augmented reality, AR)/Virtual Reality (VR) Device, a robot, a Wearable Device (VUE), a pedestrian terminal (PUE), a smart home (home Device with a wireless communication function, such as a refrigerator, a television, a washing machine, or furniture), and the like, and the Wearable Device includes: intelligent watches, intelligent bracelets, intelligent headphones, intelligent glasses, intelligent jewelry (intelligent bracelets, intelligent rings, intelligent necklaces, intelligent bracelets, intelligent footchains, etc.), intelligent bracelets, intelligent clothing, game machines, etc. Note that, the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 may be a base station or a core network device, where the base station may be referred to as a node B, an evolved node B, an access point, a base transceiver station (Base Transceiver Station, BTS), a radio base station, a radio transceiver, a basic service set (Basic Service Set, BSS), an extended service set (Extended Service Set, ESS), a node B, an evolved node B (eNB), a home node B, a home evolved node B, a WLAN access point, a WiFi node, a transmission and reception point (Transmitting Receiving Point, TRP), or some other suitable terminology in the field, and the base station is not limited to a specific technical vocabulary, and it should be noted that, in the embodiment of the present application, only a base station in the NR system is taken as an example, but the specific type of the base station is not limited thereto.

For ease of understanding, some of the matters related to the embodiments of the present application are described below:

in future communication systems, shared spectrum such as unlicensed band (unlicensed band) may be used as a supplement to licensed band (licensed band) to help operators expand services. To keep pace with NR deployments and maximize as much as possible unlicensed access based on NR, unlicensed bands may operate in the 5GHz, 37GHz and 60GHz bands. Since unlicensed bands are shared by multiple technologies (RATs), such as WiFi, radar, and LTE Licensed-Assisted Access (LTE-LAA), the unlicensed bands must be used in certain countries or regions in compliance with rules (regulations) to ensure that all devices can use the resources fairly, such as listen-before-talk (listen before talk, LBT), maximum channel occupancy time (maximum channel occupancy time, MCOT), etc. When the transmission node needs to transmit information, LBT needs to be made first, power detection (ED) is performed on surrounding nodes, and when the detected power is lower than a threshold, the channel is considered to be empty (idle), and the transmission node can transmit. Otherwise, the channel is considered as busy, and the transmission node cannot transmit. The transmission node may be a base station, a UE, a WiFi Access Point (AP), and the like. After the transmission node starts transmission, the occupied channel time COT cannot exceed MCOT.

Commonly used LBT types (category) can be classified into category1, category2 and category4.

Category1 LBT is that the transmitting node does not make LBT, i.e., has no LBT or even transmits (immediate transmission).

The Category 2LBT is a one-shot LBT, that is, the node makes one LBT before transmitting, and transmits when the channel is empty, and does not transmit when the channel is busy.

The Category 4LBT is a channel interception mechanism based on back-off, and when the transmission node detects that the channel is busy, the transmission node performs back-off, and continues interception until the channel is empty.

For the base station, category 2LBT is applied to a physical downlink shared channel (Physical downlink shared channel, PDSCH) without demodulation reference signals (Demodulation Reference Signal, DRS), category 4LBT is applied to a PDSCH, a physical downlink control channel (Physical downlink control channel, PDCCH), or an extended physical downlink control channel (ePDCCH).

For a terminal, category 4LBT corresponds to a type1 uplink channel access procedure (type 1 UL channel access procedure), and category 2LBT corresponds to type2 UL channel access procedure.

LBT includes frame-based devices (Frame Based Equipment, FBE) and load-based devices (Load Based Equipment, LBE).

Wherein, FBE means that the transmission/reception timing of the device adopts a periodic structure, and the period thereof is a fixed frame period (Fixed Frame Period, FFP). The FBE node occupies a channel using an LBT-based channel access mechanism. The node in which the transmission sequence comprising one or more consecutive transmissions is initiated is called the initiating node (Initiating Device), the other nodes being called responding nodes (Responding Device). The FBE node may be an initiating node, a responding node, or support both node functions.

For LBE, the transmitting node may start LBT from any time until it listens that the channel is empty and can transmit. For a transmitting node, there is no fixed listening time, and no need to skip when listening to the channel is busy, listening can be continued by backoff several extended clear channel assessments (Extended idle channel evaluatione, CCA) until the eCCA counter is zero.

The transmission processing method provided by the embodiment of the application is described in detail below by some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a transmission processing method according to an embodiment of the present application, as shown in fig. 2, including the following steps:

Step 201, a terminal determines N resource objects, wherein N is a positive integer;

step 202, the terminal performs target operation based on the N resource objects;

wherein the target operation includes at least one of: transmitting a first signal on at least a portion of the N resource objects and listening for at least a portion of the N resource objects; the first signal comprises at least one of a synchronization signal block and a preset signal, the resource object is a candidate resource or a candidate resource group, and the resource object is associated with a first object, and the first object comprises at least one sub-object of: a sidelink terminal, a sidelink system, a sidelink interface, sidelink traffic, priority, synchronization information, spatial information, location information, beam (beam) information, quasicontaining (QCL) information, transmission configuration indication (Transmission Configuration Indicator, TCI) information, and a sidelink set.

In this embodiment of the present application, the candidate resource and the candidate resource group both belong to a candidate resource of an unlicensed frequency band or a shared frequency band. Where a candidate resource group may include one or more candidate resources, there is no notion of a candidate resource group where a candidate resource group includes a candidate resource, i.e., the candidate resource group may be replaced with a candidate resource.

Alternatively, the resource object being used for the first signal may be understood that the resource object may be used for transmitting or detecting or listening for the first signal.

Alternatively, the above priority may be understood as SL priority, priority of a Logical Channel (LCH) or priority of (Logical channel group, LCG). The above-mentioned side link group may be understood as a SL termination group or as another group.

Alternatively, the synchronization information may include a synchronization reference, the spatial information may include a spatial reference, the position information may include a position reference, the beam information may include a beam reference, the quasi co-location information may include a quasi co-location reference, and the transmission configuration indication information may include a transmission configuration indication reference.

Alternatively, the sidelink group may be understood as a sidelink terminal group, and may include, for example, terminals corresponding to the same or preset target information, where the target information includes at least one of the following: synchronization references, spatial references, location references, beam references, QCL references, traffic, source identification (source id), destination identification (destination id), packets, process identification (process id), traffic, priority, distance, range, session, unicast (unicasts), and multicast (groupcast).

It should be understood that, in the embodiments of the present application, N resource objects may be configured or preconfigured for a terminal based on the first object, so that the terminal obtains candidate resources. Alternatively, if the first object determines that the channel is available, the terminal may perform the target operation based on the N resource objects. Transmission in embodiments of the present application may be understood as either sending or receiving. Listening to at least part of the N resource objects may be understood as listening to whether the channel or carrier on which the N resource objects are located is idle, available or busy.

It should be noted that the preset signal may be at least part of the synchronization signal block, i.e. the synchronization signal block may also be used to mark one or more SL systems, sidelink interfaces, sidelink traffic, sidelink groups or priorities, and may also be used to mark one or more synchronization references and/or spatial references and/or location references and/or beam references and/or QCL references. For example, the synchronization signal block or the preset signal may identify at least one of:

a sidelink terminal, a sidelink system, a sidelink interface, a sidelink service, a priority, synchronization information, spatial information, position information, beam information, quasi co-location information, transmission configuration indication information, an occupation situation of a sidelink group and a second object;

Wherein the second object is a channel, carrier or resource.

It should be noted that, identifying a sidelink terminal may be understood as identifying any sidelink terminal or a preset sidelink terminal; identifying a sidelink system may be understood as identifying any sidelink system or a preset sidelink system; identifying a sidelink interface may be understood as identifying any sidelink interface or a preset sidelink interface; identifying a priority may be understood as identifying any priority or a preset priority; the identification synchronization information can be understood as any synchronization information or preset synchronization information; the identification space information can be understood as any space information or preset space information; the identification position information can be understood as any position information or preset position information; identifying beam information may be understood as identifying any beam information or preset beam information; the identification of the quasi co-located information can be understood as identifying any quasi co-located information or preset quasi co-located information; the identification of the transmission configuration indication information can be understood as identifying any transmission configuration indication information or preset transmission configuration indication information; identifying a sidelink group may be understood as identifying any sidelink group or a preset sidelink group; identifying a second object may be understood as identifying any second object or a preset second object.

Alternatively, the above-mentioned channel refers to a channel listening to when it is idle or busy. The above-mentioned Resource may be understood as a Resource Block (RB) or a Resource (Resource block group, RBG).

Optionally, in some embodiments, the preset signal is any one of the following:

a portion of the first signal;

other synchronization signal blocks than the synchronization signal block;

a preamble.

In this embodiment of the present application, the synchronization signal block in the first signal may be referred to as a first synchronization signal block, and the other synchronization signal blocks may be referred to as second synchronization signal blocks.

It should be noted that, the portion of the first signal may be understood as a portion of a first synchronization signal block, where the portion of the first signal may be a primary synchronization sequence (Primary Synchronisation Sequence, PSS) and/or a secondary synchronization sequence (Secondary Synchronisation Sequence, SSS). Optionally, in the case that the first time is located before the start time of the target resource object and the interval between the first time and the start time of the target resource object is greater than or equal to a fourth preset value, the portion of the first signal may be understood as a portion of the first signal corresponding to the first time on the target resource object to before the end of the target resource object. The second synchronization signal block may be another synchronization signal block of at least two items SSS, PSS, PSBCH that are combined in an FDM manner. Or another synchronization signal block in which at least two of the SSS, PSS, physical sidelink broadcast channels (Physical Sidelink Broadcast Channel, PSBCH) are combined in a TDM manner and which is different from the first synchronization signal block structure. I.e. there are two types of synchronization signal blocks, e.g. if in the synchronization signal block candidate resource after a channel is preempted, a second synchronization signal block is sent as a result of being unable to send a complete first synchronization signal block, and if the synchronization signal block candidate resource starts after a channel is preempted, a first synchronization signal block is transmitted.

It should be noted that the N resource objects may belong to L target time objects, where the target time objects include a period, a timer, a time window, a transmission cluster, a preset time period, a channel occupation time, or a time domain unit, and the resource objects are candidate resources or candidate resource groups. Wherein the target time object comprises a running duration of the timer when the timer is to be understood as the target time object. The time domain unit may be a slot (slot), a sub-slot (mini slot), a frame (frame), a subframe (subframe), a millisecond (ms), a symbol (symbol), or a span (span). The predetermined time may be a period or duration, for example, a frame period (frame period). The above-mentioned transmission cluster may be understood as a group (group), a cluster (cluster), a set (set), or a burst.

Optionally, in some embodiments, the first object satisfies at least one of:

in the case that a plurality of first sub-objects are associated with the same second sub-object, at least part of candidate resources in candidate resources or candidate resource groups associated with the plurality of first sub-objects are the same;

in the case that at least two first sub-objects of the plurality of first sub-objects are associated with a different second sub-object, at least some candidate resources of the candidate resource or candidate resource group associated with the plurality of first sub-objects are different;

In the case that at least two first sub-objects in the plurality of first sub-objects are associated with a different second candidate resource object, at least part of candidate resources or candidate resource groups associated with the at least two first sub-objects are different;

wherein the first sub-object and the second sub-object are different sub-objects in the first object.

Optionally, the at least part of the candidate resources are a first candidate resource set, which is available for the first signal.

In this embodiment, the first candidate resource group may be used for the second object, which may be understood that the first candidate resource group is specific to the second object, that is, the first candidate resource group may only be used for transmitting or detecting the second object.

For example, in some embodiments, at least some of the first candidate resource groups and/or candidate resources corresponding to multiple UEs belonging to the same SL system or the same synchronization reference or the same SL UE group are the same. Wherein the first candidate resource group and/or candidate resource is used for the first signal.

For example, in some embodiments, the first candidate resource group and/or the synchronization signal block candidate resource corresponding to a plurality of UEs belonging to different SL systems or different synchronization references or different SL UE groups are at least partially different.

Optionally, in the case that the plurality of first sub-objects are associated with the same second sub-object, at least part of a second candidate resource group associated with the plurality of first sub-objects is different, the second candidate resource group being available for the first signal and the first sidelink signal.

The second candidate resource group may be understood as a candidate resource group that may be used for the first signal and the first sidelink signal, and may be used for transmitting only at least one of the first signal and the first sidelink signal when actually used.

For example, in some embodiments, the first candidate resource groups corresponding to the plurality of UEs are the same, but the second candidate resource groups corresponding to the plurality of UEs may be the same or different; for example, a synchronization reference corresponds to a first candidate resource group and two second candidate resource groups, with both UE1 and UE corresponding to the first candidate resource group but to a different second candidate resource group.

Optionally, the first sidelink signal comprises at least one of: at least one of a data channel, a control channel, a feedback channel, and a reference signal.

Optionally, in some embodiments, the performing, by the terminal, a target operation based on the N resources includes:

wherein the target terminal satisfies at least one of: the target terminal is other terminals except the terminal; the target terminal is a terminal in communication with the terminal.

Further, the terminal and the target terminal are associated with the same first object.

In this embodiment of the present application, the terminal may transmit the first signal on a preset resource object among the N candidate resource objects. The preset resource object may be a resource object after detecting or receiving the target resource object of the first signal. For example, in some embodiments, the preset resource object may be a resource object that is located after the target resource object and that is recent (or arbitrary, or preset), or a candidate resource that is located within a candidate resource group where the target resource is located.

For example, the UE receives a synchronization signal block on a certain candidate resource in the first candidate resource group, and then transmits a synchronization signal on the last candidate resource thereafter, or transmits a synchronization signal on a candidate resource in the second candidate resource group thereafter, or transmits a synchronization signal on a candidate resource in the first candidate resource group thereafter.

For example, SL sync reference 1 corresponds to candidate resource 1 and candidate resource 2, UE1 and UE2 both use SL sync reference 1, UE1 preempts the channel and transmits a sidelink synchronization signal block (Sidelink Synchronization Signal and PBCH block, S-SSB) using candidate resource 1, UE2 considers that the UE using SL sync reference 1 has acquired the usage rights of the channel after receiving the S-SSB, so that UE2 can transmit the S-SSB using resource 2.

Optionally, in some embodiments, the bearer information of the first signal bearer includes at least one of:

the second indication information is used for indicating the codes of the candidate resource groups where the first signals are located;

the third indication information is used for indicating the number of the candidate resource where the first signal is located;

In this embodiment of the present application, the second indication information may specifically indicate whether the first signal belongs to the first candidate resource group or the second candidate resource group. Optionally, in the case that the first signal belongs to the first candidate resource group, the third indication information may indicate a number of the first candidate resource group where the first signal is located; in the case that the first signal belongs to the second candidate resource group, the fourth indication information may indicate the number of the second candidate resource group in which the first signal is located.

Alternatively, the information about the channel occupation time COT may be understood as information about a channel, carrier, resource or COT on which the first signal is located. For example, at least one of the following may be included:

the first signal corresponds to several channels and/or carriers;

which channels and/or carriers the first signal corresponds to;

at least one of a start point, a terminal, and a duration of the COT; i.e. the time period within which the channel and/or resource is occupied;

Whether it can be used by other first sub-objects under the same second sub-object. For example, UE1 preempts the channel and sends an S-SSB and indicates that the same synchronization reference it uses can also use the channel on which the S-SSB is located.

Optionally, the fifth indication information may include at least one of:

first sub-indication information for indicating whether a candidate resource or a candidate resource group is used for the related information of the synchronization signal block;

sixth sub-indication information for indicating related information of a candidate resource or a candidate resource group used for the first sidelink signal;

Seventh sub-indication information for indicating whether a candidate resource or a candidate resource group can be used for the related information of the first sidelink signal;

eighth sub-indication information indicating information about candidate resources or candidate resource groups that can be used for the first sidelink signal.

In this embodiment of the present application, the first indication information may be specifically used to indicate whether a certain or some candidate resource or candidate resource group is used for the synchronization signal block; the second sub-indication information may be specifically used to indicate whether a certain or some candidate resource or candidate resource group is used for a preset signal; the third sub-indication information may be specifically used to indicate how many and/or which candidate resources or candidate resource groups are used for the synchronization signal block; the fourth sub-indication information may be specifically used to indicate how many and/or which candidate resources or candidate resource groups are used for the preset signal; the fifth sub-indication information may in particular be used to indicate whether a certain or some candidate resource or group of candidate resources (e.g. have been or will) is/are used for the first sidelink signal; the sixth sub-indication information may be specifically used to indicate how many and/or which candidate resources or candidate resource groups (e.g. have been or will be used for the first sidelink signal); the seventh sub-indication information may specifically be used to indicate whether a certain or some candidate resource or group of candidate resources may be used for the first sidelink signal; the eighth sub-indication information may specifically be used to indicate that a certain or some candidate resource or set of candidate resources may be used for the first sidelink signal.

It should be understood that an object used in the embodiments of the present application may be understood as a candidate resource for the object, or may be selected for the object, or may be reserved for the object. For example, the candidate resource or candidate resource group being used for the synchronization signal block may be understood as: the candidate resource or the set of candidate resources is a candidate resource for a synchronization signal block, or the candidate resource or the set of candidate resources is selected for a synchronization signal block, or the candidate resource or the set of candidate resources is reserved for a synchronization signal block.

Alternatively, the type of the first signal may be understood as whether the first signal is a synchronization signal block, a preset signal, or a synchronization signal block and a preset signal.

Optionally, the related information of the first signal includes information of a first object associated with a resource object where the first signal is located.

For example which sidelink terminal and/or SL system and/or SL UE group and/or synchronization reference and/or spatial reference and/or location reference and/or beam reference and/or QCL reference the terminal corresponds to.

Optionally, in some embodiments, the information carried by M first signals is at least partially the same, where the M first signals are at least partial first signals transmitted based on the N resource objects, and M is a positive integer less than or equal to N.

Optionally, the M first signals are associated with at least one of: the same candidate resource group, the same first candidate resource group, the same second candidate resource group, the same time window and the same period;

wherein one of the candidate resource groups comprises at least one of a first candidate resource group and a second candidate resource group, the first candidate resource group being available for the first signal and the second candidate resource group being available for the first signal and a first sidelink signal.

In this embodiment of the present application, at least part of the bearer information carried by at least part of the first signal in the same candidate resource group or the same first candidate resource group or the same second candidate resource group or the same period is the same. For example, at least the portion carried over the broadcast channel is the same.

Embodiment one: the UE can transmit within any system and/or reference under the same system and/or synchronization reference.

Assuming that each cycle contains two candidate resource groups (e.g., candidate resource group 1 and candidate resource group 2), in one implementation the information corresponding to the synchronization signal blocks within each candidate resource group is generated at each cycle, as shown in fig. 3. In another implementation manner, if the terminal determines that it can use the second candidate resource group for transmission before the second candidate resource group in the first period (as shown in time n of fig. 4), the terminal starts to generate information corresponding to the synchronization signal block in the second candidate resource group; before the first candidate resource group in the second period (time m shown in fig. 4), it is determined that the first candidate resource group and the second candidate resource group can be used for transmission, and then the generation of information corresponding to the two intra-group synchronization signal blocks starts in the first candidate resource group.
