In the above technical solution, the first communication device may determine whether the resource used by the second communication device may be occupied according to the adjusted reference information. Therefore, the technical scheme improves the flexibility of preempting the resources.

With reference to the first aspect, in a possible implementation manner of the first aspect, the controlling information further includes a service type indication field, where the service type indication field is used to indicate a service type of the second communication device, and the first communication device determines whether to use the target resource according to the target offset value, including: the first communication device determines whether to use the target resource according to the target offset value and the service type of the second communication device.

In order to facilitate those skilled in the art to better understand the technical solution of the present application, a description will be first given of a scenario in which the technical solution of the present application can be applied. The technical scheme of the application can be applied to device-to-device (D2D) communication. Devices that communicate using D2D may be referred to as D2D devices. The communication device referred to in the embodiments of the present application may also be a D2D device.

In order to improve the spectrum utilization rate and utilize the radio frequency capability of the existing terminal equipment to the maximum extent, the D2D communication link, i.e. the Side Link (SL), is considered to reuse the spectrum resources of the existing mobile communication network. In order not to interfere with terminal devices of existing networks, D2D communication does not use the spectrum resources of the downlink (i.e. network device to terminal device) but only multiplexes the spectrum resources of the uplink (i.e. terminal device to network device). Because the anti-interference capability of the network equipment is much better than that of the common terminal equipment. The D2D device is more likely to be time division multiplexed on the uplink spectrum resources, and thus does not need to support simultaneous transceiving, requiring only either transmission or reception at one time.

In the third generation partnership project (3)^rdGeneration Partnership Project, 3GPP) Rel-12/13, the D2D scenario can be divided into 3 devices with network coverage, partial network coverage and no network coverage. The D2D device is in the coverage range of the network device in the scene of network coverage; the partial network coverage scenario has a portion of D2D devices within the coverage of the network device and another portion of D2D devices not within the coverage of the network device; in a scenario without network coverage, all D2D devices are not in the coverage area of the network device. If the terminal equipment can hear the signal of the network equipment, the terminal equipment in the network coverage is selected. If the terminal device can hear the signal of the terminal device in the network coverage, the terminal device is a partial network coverage terminal device. If the first two kinds of signal terminal equipment can not be received, the terminal equipment is the terminal equipment outside the network coverage. As shown in fig. 1, terminal device 1 belongs to a terminal device within a network coverage area, terminal device 2 belongs to a terminal device with partial network coverage, and terminal devices 3, 4 and 5 belong to terminal devices outside the network coverage area.

D2D communication can be divided into two types, D2D device discovery and D2D device communication, D2D device discovery transmits only discovery signals, D2D device communication transmits Scheduling Assignment (SA) and data, and D2D communication link is called Side Link (SL) as opposed to uplink and downlink in LTE, LTE-a or 5G systems, etc.

From the perspective of the sending user (sending device), the resource allocation for D2D device communication now has two modes.

Mode one (Mode 1): the method is a centralized control type method, the resources of D2D are allocated by a central control device, such as a network device or a relay station, the resources are allocated to the transmitting terminal for use by a scheduling method, and the centralized control type resource allocation mainly aims at a network coverage scenario.

Mode two (Mode 2): the method is a distributed resource multiplexing method based on competition, and the sending equipment obtains sending resources from a resource pool in a competition mode. In a network coverage scenario, the resource pool is a whole block of resources divided by the network device, and all D2D devices compete for a small block of resources in the whole block of resources. In the scenario without network coverage, the resource pool is that D2D devices can obtain a predefined block of system bandwidth, and all D2D devices compete for resources under the predefined resource.

Similar to device communication, there are two types of resource allocation for device discovery.

Type one (Type 1): the method is a distributed resource multiplexing method based on competition, and the sending equipment obtains sending resources from a resource pool in a competition mode. In a network coverage scenario, the resource pool is a whole block of resources divided by the network device, and all D2D devices compete for a small block of resources in the whole block of resources. In the scenario without network coverage, the resource pool is that D2D devices can obtain a predefined block of system bandwidth, and all D2D devices compete for resources under the predefined resource.

Type two (Type 2): the method is a centralized control type method, the resources of D2D are allocated by a central control device, such as a network device or a relay station, the resources are allocated to the transmitting terminal for use by a scheduling method, and the centralized control type resource allocation mainly aims at a network coverage scenario.

It should be understood that for the contention-based resource allocation method of Mode2 and Type 1, since there is no coordination of the central controller, different terminal devices may compete for the same resource, and thus a collision occurs; when the number of terminal devices is large, the probability of such a collision situation is high.

For example, for D2D device communication, a sending device first sends a Scheduling Assignment (SA), (sends 2 times repeatedly), such as Sidelink Control Information (SCI), which carries resource information of a data packet, and then sends the data packet (sends 4 times repeatedly), fig. 2 shows a schematic diagram of Mode 1, Mode2 is similar, except that there is no network device, and the resource is randomly selected by the sending device or finds available resource based on auto-sensing/detection; the receiving equipment firstly carries out blind detection on the SA, and receives the data packet according to the resource information of the data packet carried in the SA. The auto-sensing/detecting to find available resources includes signal strength or signal energy detection, and detecting SCIs sent by surrounding devices to determine which resources are available.

Currently, SA now has only SCI format 0(SCI format 0) in one format, and SCI format 0 includes fields as shown in table 1 below.

Besides D2D communication, the technical solution of the present application can also be used in Vehicle to Everything (V2X) technology.

In 3GPP Rel-14/15/16 release, V2X has established itself well as a major application of D2D technology. The V2X optimizes the specific application requirements of V2X based on the existing D2D technology, and needs to further reduce the access delay of V2X devices and solve the problem of resource conflict.

V2X includes, in particular, Vehicle to Vehicle (V2V), Vehicle to pedestrian communication (V2P), Vehicle to Infrastructure (V2I), Vehicle to network (Vehicle to network) requirements. V2V refers to mobile network based inter-vehicle communication; V2P refers to mobile network-based communication of a vehicle with a person (including a pedestrian, a cyclist, a driver, or a passenger); V2I refers to mobile network-based communication between a vehicle and a roadside apparatus (RSU); V2N refers to mobile network based communication of a vehicle with a base station/network.

RSUs may include two types: the RSU of the terminal equipment type is distributed on the roadside, so that the RSU of the terminal type is in a non-mobile state and does not need to consider the mobility; the RSU, which is a type of network device, can provide timing synchronization and resource scheduling to the vehicle with which it communicates.

From the perspective of the entire V2X system, the transmission resources of the entire V2X can be divided into several sub-channels. The control information and data resources transmitted and received are also relatively fixed for the transmitting device and the receiving device. And the receiving end receives the SA in the resource pool where the control information is positioned, and further decodes the data according to the control information carried in the SA.

A sub-channel comprises several Resource Blocks (RBs) that are consecutive in the frequency domain, and the size of the sub-channel can be configured by the network device or pre-configured in advance. Any one of the sub-channels may be used for transmission of V2X data information. For example, in one sub-channel, starting from the lowest RB number (lowest index of the RB), a total of two consecutive RBs are physical side link control channels (PSCCHs) for transmitting V2X control information, and the remaining consecutive RBs are physical side link shared channels (PSCCHs) for transmitting data (data). In the time domain, a subframe (subframe), a slot (slot), or a symbol (symbol) is used as a basic unit. Further, in LTE V2X, SA and data are in frequency domain and Frequency Division Multiplexing (FDM) form, and the whole subframe is occupied in time domain. It should be understood that a plurality of sub-channels may be included on one partial Bandwidth (BWP).

Further in the 5G NR system, new PSCCH and PSCCH resource allocation options are introduced, so, by way of example only, in practice PSCCH and PSCCH may be split on time domain resources (partitioned), split on frequency domain resources (partitioned), or overlapped and PSCCH is a part of them. When the resource is divided, the combination may be performed with reference to the various time domain units and frequency domain units described above.

As described above, the embodiment of the present application can be applied to D2D communication. In this case, the first communication device and the second communication device in the embodiment of the present application may be two terminal devices.

Alternatively, the second communication device may be a vehicle or an in-vehicle device provided in the vehicle, and the first communication device may be a terminal device carried by a pedestrian, such as a mobile phone, a wearable device having a wireless communication function, or the like.

The service type referred to in the embodiments of the present application may also be referred to as a communication type. Embodiments of the present application will be described in detail below with reference to specific examples. It should be noted that the above-mentioned embodiments are only for helping those skilled in the art to better understand the embodiments of the present application, and do not limit the scope of the embodiments of the present application.

It should be understood that in the embodiments of the present application, "first", "second", etc. are only intended to refer to different objects, and do not indicate other limitations to the objects referred to.

301, the first communication device receives control information sent by the second communication device, where the control information includes an offset value indication field, and the offset value indication field is used to indicate a target offset value.

The first communications device determines 302 whether to use a target resource based on the target offset value, wherein the target resource is a resource occupied by the second communications device.

The first communication device and the second communication device may transmit data using the same resource. The resource referred to in the embodiments of the present application may be at least one of a time domain resource, a frequency domain resource, or a spatial domain resource. For example, if the resource is a time domain resource, the time domain resource may be a combination of any one or more of a symbol (symbol), a slot (slot), a mini-slot (mini-slot), or a subframe (subframe). As another example, if the resource is a frequency domain resource, the resource may be any one or more of a Resource Element (RE), a Resource Block (RB), a Physical Resource Block (PRB), and a sub-channel (sub-channel). If the resource is a spatial domain resource, the resource may be a beam (beam) or an antenna port.

As described above, the embodiment of the present application may be applied to D2D communication or V2X, and thus, the resource in the embodiment of the present application may be an edge link resource.

Optionally, in some embodiments, the first communication device and the second communication device may share the same resource pool, where the resource pool includes multiple resources. The first communication device and the second communication device may transmit data using resources in the resource pool.

Optionally, in other embodiments, the resource pool used by the first communication device is different from the resource pool used by the second communication device. But the first communication device may occupy a resource in a resource pool used by the second communication device.

When the second communication device uses a certain resource (e.g., the target resource) to transmit data, the second communication device sends control information, which may include reference information of the second communication device.

Optionally, in some embodiments, unicast (unicast) refers to point-to-point transmission, i.e. data transmission between one communication device and another communication device; multicast (group host), also called multicast (multicast), refers to multicast-to-multipoint transmission, i.e. data transmission is performed between one communication device and another communication devices, wherein the another communication devices and the one communication device belong to the same group or the same set; broadcast (broadcast) also refers to multicast transmission, i.e. data transmission between a communication device and surrounding communication devices, which all listen, detect and parse the data. Typically, channel measurement feedback, and/or feedback for data transmission, is considered in unicast; the multicast may take into account channel measurement feedback, and/or feedback of data transmission; the broadcast generally does not consider channel measurement feedback, and/or feedback for data transmission. Therefore, when unicast is transmitted together with multicast/broadcast, the priority of unicast is higher; multicast is transmitted with broadcast, the priority of multicast is higher.

Optionally, in some embodiments, the data transmitted by the communication device may be divided into aperiodic data (aperiodic data) and periodic data (periodic data). Aperiodic data transmission is dynamically triggered and not periodically sustained; the periodic data is semi-static configuration or semi-static configuration plus dynamic trigger, and is transmitted periodically, or within a certain window or duration (duration). For example semi-persistent (semi-persistent) transmission.

The traffic type of the data transmission may vary. In one aspect, the traffic type of the data transmission may include one or more of unicast, multicast, or broadcast. The above can also be summarized in that the traffic type of the data transmission may include one or more of unicast or non-unicast. On the other hand, the traffic type of the data transmission may further include one or more of aperiodic and periodic.

For example, in some embodiments, the second reference information is a PPPP of the second communication device. Assuming that the PPPP of the second communication device is PPPP2, the modified reference information may be PPPP 2', where PPPP2 ═ PPPP2+ offset, where offset represents the target offset value, and the target offset value may be a positive integer greater than or equal to 1.

Optionally, in other embodiments, the determining, by the first communication device, the modified reference information according to the second reference information and the target offset value may be: the first communications device determines the modified reference information as a product of the second reference information field and the target offset value. For example, in some embodiments, the second reference information is a PPPP of the second communication device. Assuming that the PPPP of the second communication device is PPPP2, the modified reference information may be PPPP2 ', where PPPP 2' is PPPP2 × offset, where offset represents the target offset value, and the target offset value may be a number greater than 1.

The second reference information and the target offset value are arguments of the binary function, and the dependent variable of the binary function is the modified reference information. For example, assuming that the reference information is PPPP, the binary function f (PPPP, offset) may be f (PPPP, offset) ═ PPPP + offset + 2. Assuming that the PPPP of the second communication device is PPPP2, the modified reference information PPPP2 ', where PPPP 2' is PPPP2+ offset +2, where offset represents the target offset value, and the target offset value may be a positive integer greater than or equal to 1.

For example, in some embodiments, the first reference information is a PPPP of the first communication device. Assuming that the PPPP of the first communication device is PPPP1, the modified reference information may be PPPP 1', where PPPP1 ═ PPPP1-offset, where offset represents the target offset value, and the target offset value may be a positive integer greater than or equal to 1. As another example, in some embodiments, the first reference information is a QoS identification of the first communication device. Assuming that the QoS identifier of the first communication device is QoS1, the modified reference information may be QoS1 ', where QoS 1' is QoS 1-offset, where offset represents the target offset value, and the target offset value may be a positive integer greater than or equal to 1.

Optionally, in other embodiments, the first communication device may also determine the modified reference information according to a function. For example, the function is a binary function. The first reference information and the target offset value are arguments of the binary function, and the dependent variable of the binary function is the modified reference information. For example, assuming that the reference information is PPPP, the binary function f (PPPP, offset) may be f (PPPP, offset) ═ PPPP + offset + 2. Assuming that the PPPP of the first communication device is PPPP1, the modified reference information PPPP 1', where PPPP1 ═ PPPP 1+ offset +2, where offset represents the target offset value, and the target offset value may be a positive integer greater than or equal to 1.

In the prior art, when a detecting communication device detects a certain resource, it is necessary to obtain the PPPP in the control information on the detected resource and the specific location of the resource (referred to as a target resource), and compare the PPPP of the detecting communication device with the PPPP on the detected resource. The corresponding threshold at the intersection of the PPPP of the detecting communication device itself and the PPPP on the detected resource is taken from table 2 and may be referred to as a target threshold. If the signal strength of the target resource satisfies the target threshold, or if the signal strength of the control information is less than or equal to the target threshold, the target resource may be used, otherwise the target resource may not be used. The signal strength of the target resource meeting the target threshold means that the signal strength detected by the communication device at the target resource is detected to be less than or equal to the target threshold. The signal strength of the control information meeting the target threshold means that the signal strength of the detected control information SCI is less than or equal to the target threshold. The detected Signal strength may be any one of Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ), Received Signal Strength Indicator (RSSI), Signal-to-interference-and-noise ratio (SINR).

PPPP1a to PPPP8a in table 2 indicate PPPPs that detect communication devices, and PPPP1b to PPPP8b indicate PPPPs in control information, where PPPP1a to PPPP8a are respectively different PPPPs. In other words, any two PPPPs of PPPP1a to PPPP8a are different. Similarly, PPPP1b to PPPP8b are different PPPPs, respectively. In other words, any two PPPPs of PPPP1b to PPPP8b are different. PPPP1a may be the same as PPPP1b, PPPP2a may be the same as PPPP2b, and so on. The preset preemption threshold shown in table 2 includes 64 thresholds in total. Optionally, in some embodiments, any two thresholds TH1 to TH64 are different. Alternatively, in other embodiments, the partial thresholds at the middle of TH1 through TH64 may be the same.

For example, if the PPPP of the communication device is detected to be PPPP1a and the PPPP in the control information is PPPP6b, the target threshold is TH 6. In another example, if the PPPP of the communication device is detected to be PPPP8a and the PPPP in the control information is detected to be PPPP1b, the target threshold is TH 57.

It is to be understood that table 2 shows the correspondence between the PPPPs of the 8 detected communication devices themselves and the PPPPs of the 8 detected resources, and the preset preemption threshold includes 64 thresholds. In other embodiments, the correspondence between the PPPP of the communication device itself and the PPPP of the detected resource may be other numbers, for example, 6 × 6, 12 × 12, and the like, and correspondingly, the number of the preset preemption threshold may also be other numbers, which is not necessarily listed here.

The signal strength of the target resource meeting the target threshold means that the signal strength detected at the target resource is less than or equal to the target threshold. The detected signal strength may be any one of RSRP, RSRQ, RSSI, SINR.

Also taking table 2 as an example, the preset preemption threshold shown in table 2 includes 64 thresholds in total. The first communications device may determine the target threshold from the preset preemption thresholds by: the first communication device may determine that the threshold at which the first reference information (i.e., the PPPP of the first communication device) crosses the revised reference information (i.e., the revised PPPP determined from the PPPP of the second communication device and the target offset value) in table 2 is the target threshold.

For example, if the PPPP of the first communication device is PPPP1a and the PPPP after the correction is PPPP6b, the target threshold is TH 6. In another example, if the PPPP of the first communication device is PPPP8a and the modified PPPP is PPPP1b, the target threshold is TH 57.

For another example, if the PPPP of the first communication device is PPPP8a and the PPPP of the second communication device is PPPP1b, the target threshold is TH 57.

Alternatively, the positions in the table corresponding to the same intersections may or may not be completely different. Wherein the preemption threshold corresponding to the same intersection location, e.g., the intersection of PPPP3a and PPPP4b, is TH20 in table 2, TH20 'in table 5, and TH 20' in table 6, which may be quite different from one another; alternatively, TH20 may be the same as TH 20', but different from TH20 "; alternatively, TH20 may be the same as TH20 ", but different from TH 20', etc.

Also, in different tables (i.e., table 2, table 5, table 6), the different crossover locations may or may not be completely different.

Optionally, in some embodiments, the determining whether the target resource can be used according to the first reference information, the second reference information, and the first preset preemption threshold includes: if the first service type is a unicast service and the second service type is a broadcast service, a multicast service or a non-unicast service, determining whether to use the target resource according to the first reference information, the second reference information and a first preset preemption threshold shown in table 6; if the second service type is a unicast service and the first service type is a broadcast service, a multicast service or a non-unicast service, determining whether to use the target resource according to the first reference information, the second reference information and a first preset preemption threshold shown in table 5.

Optionally, in some embodiments, the determining whether the target resource can be used according to the first reference information, the second reference information, and the first preset preemption threshold includes: if the first service type is a multicast service and the second service type is a broadcast service, determining whether to use the target resource according to the first reference information, the second reference information and a first preset preemption threshold shown in table 6; if the second service type is a multicast service and the first service type is a broadcast service, determining whether to use the target resource according to the first reference information, the second reference information and a first preset preemption threshold shown in table 5.

If the first communication device determines that the service type of the first communication device is the same as the service type of the second communication device, determining whether the target resource can be used according to the first reference information, the second reference information and a second preset preemption threshold shown in table 2.

The implementation manner of how the first communication device determines whether the target resource can be used according to the reference information and the preset preemption threshold may refer to the embodiment shown in fig. 1, and thus details are not needed here.

Optionally, in some other embodiments, in some cases, even if the first service type is the same as the second service type, the first communication device may determine a preemption threshold according to a preset preemption threshold.

For example, if the first service type and the second service type are both unicast services or non-periodic services, the first communication device may determine a first preemption threshold according to a first offset value and the preset preemption threshold; if the first service type and the second service type are both multicast service, broadcast service or periodic service, the first communication device may determine a second preemption threshold according to a second offset value and the preset preemption threshold.

For another example, if the first service type and the second service type are both multicast services, the first communication device may determine a first preemption threshold according to a first offset value and the preset preemption threshold; if the first service type and the second service type are both broadcast services, the first communication device may determine a second preemption threshold according to a second offset value and the preset preemption threshold. The first offset value, the second offset value, and the target offset value may be different.

The determination manner in which the first communication device determines the first preemption threshold (or the second preemption threshold) based on the first offset value (or the second offset value) and the preset preemption threshold is similar to the determination manner in which the first communication device determines the target offset value based on the target offset value and the preset preemption threshold, which is not described herein again.

601, the first communication device receives control information sent by the second communication device, where the control information includes an offset value indication field and a transmission mode indication field, the offset value indication field is used to indicate a target offset value, and the transmission mode indication field is used to indicate a transmission mode of the second communication device.

Or, optionally, the first communication device receives control information sent by the second communication device, where the control information includes a transmission mode indication field and does not include an offset value indication field, and the transmission mode indication field is used to indicate a transmission mode of the second communication device. The target offset value may be preset at the first communication device or sent to the first communication device by the network device through RRC signaling or MAC signaling.

The first communications device determines whether to use a target resource in dependence on the transmission mode of the second communications device and the target offset value, wherein the target resource is a resource used by the second communications device 602.

When the second communication device uses a certain resource (e.g., the target resource) to transmit data, the second communication device sends control information, which may include reference information of the second communication device. Optionally, in some embodiments, the reference information may be priority information. For example, the reference information may be PPPP. As another example, the reference information may be a priority of the communication device set in advance. Optionally, in other embodiments, the reference information may be quality of service (QoS) information. The QoS information may be a QoS class. The QoS class may be a QoS identification (QoS identification) or a QoS index (QoS index). For convenience of description, the reference information of the first communication apparatus is hereinafter referred to as first reference information, and the reference information of the second communication apparatus is hereinafter referred to as second reference information. Optionally, in some embodiments, the control information may Schedule Control Information (SCI). Optionally, in some embodiments, the SCI may be Downlink Control Information (DCI) 5A. Optionally, in other embodiments, the SCI may be DCI X. Optionally, in other embodiments, the control information may be DCI 5B or DCI Y.

The transmission mode may include a first transmission mode and a second transmission mode. In other words, the transmission mode of the second communication device may be the first transmission mode or the second transmission mode. Optionally, in some embodiments, the first transmission mode may be a base station scheduling mode, and the second transmission mode may be a mode in which resource selection is performed based on automatic sensing or automatic detection by the communication device.

Optionally, in some embodiments, the transmission mode indication field may include 1 bit, in which case the transmission mode indication field may indicate 2 transmission modes. For example, if the bit value is 0, the transmission mode of the second communication device indicated by the transmission mode indication field is the first transmission mode; if the bit value is 1, the transmission mode of the second communication device indicated by the transmission mode indication is a second transmission mode.

Optionally, in some embodiments, the transmission mode indication field may include 2 bits, in which case the transmission mode indication field may indicate 4 transmission modes. For example, if the bit value is 00, the transmission mode of the second communication device indicated by the transmission mode indication field is the first transmission mode; if the bit value is 01, the transmission mode of the second communication device indicated by the transmission mode indication is a second transmission mode. For example, if the bit value is 10, the transmission mode of the second communication device indicated by the transmission mode indication field is a third transmission mode; if the bit value is 11, the transmission mode of the second communication device indicated by the transmission mode indication is a fourth transmission mode.

Optionally, in other embodiments, the transmission mode indication field may further include 3 or more bits, which are not listed here.

Alternatively, in some embodiments, the transmission mode indication field may not be indicated by a bit, but may be embedded implicitly in the existing information. For example, it is possible to indicate whether the transmission mode is mode 1 or mode2 by setting an existing information bit to a specific value. Also for example, some reserved bits in the existing control message may be set to a specific value to indicate whether the transmission mode is mode 1 or mode 2. The information bits or reserved bits may refer to existing information bits or reserved bits in a current mobile communication system (e.g., an LTE system), and are not described in detail.

Optionally, in some embodiments, the determining, by the first communication device, whether to use the target resource according to the transmission mode of the second communication device includes: the first communication device may determine whether to use the target resource according to the first reference information, the second reference information, and the target offset value, when determining that the transmission mode of the second communication device is the first transmission mode; the first communication device may determine whether to use the target resource according to the first reference information and the second reference information when determining that the service type of the second communication device is the second transmission mode.

Optionally, in other embodiments, the target offset value may also be preset in the first communication device or sent to the first communication device by the network device.

Optionally, in some embodiments, the N pieces of first reference information are different from the M pieces of second reference information, and include: the N first reference information and the M second reference information are not identical. Optionally, in some other embodiments, the N pieces of first reference information are different from the M pieces of second reference information, and include: the N first reference information and the M second reference information are completely different.

Optionally, in some embodiments, the N first reference information may be considered to be different from the M second reference information as long as there is a difference between the N first reference information and the M second reference information. For example, if the value of M is not equal to N, the N pieces of first reference information are different from the M pieces of second reference information. If M is equal to N, the M pieces of reference information correspond to the N pieces of reference information one to one, and as long as a group of corresponding reference information in the N pieces of first reference information and the M pieces of second reference information is different, the N pieces of first reference information are different from the M pieces of second reference information.

Assume that M and N both take on the value 5. The 5 pieces of first reference information are reference information 1a to reference information 5a, respectively, and the 5 pieces of second reference information are reference information 1b to reference information 5b, respectively. The reference information 1a corresponds to the reference information 1b, the reference information 2a corresponds to the reference information 2b, the reference information 3a corresponds to the reference information 3b, the reference information 4a corresponds to the reference information 4b, and the reference information 5a corresponds to the reference information 5 b.

In some embodiments, if the reference information 1a is different from the reference information 1b, the reference information 2a is the same as the reference information 2b, the reference information 3a is different from the reference information 3b, the reference information 4a is the same as the reference information 4b, and the reference information 5a is different from the reference information 5b, then the 5 first reference information are considered to be different from the 5 second reference information.

Optionally, in some embodiments, the reference information may be priority information. For example, the reference information may be PPPP. As another example, the reference information may be a priority of the communication device set in advance. Accordingly, the N first reference information may be N first priority information, and the M reference information may be M second priority information.

Optionally, in other embodiments, the reference information may be QoS information. The QoS information may be a QoS class. The QoS class may be a QoS identification (QoS identification) or a QoS index (QoS index). Accordingly, the N first reference information may be N first QoS information, and the M reference information may be M second QoS information.

Optionally, in some embodiments, the first configuration information corresponds to a first service type, and the second configuration information corresponds to a second service type. In other words, if the first configuration information includes N pieces of first priority information and the second configuration information includes M pieces of second priority information, the N pieces of first priority information correspond to the first service type and the M pieces of second priority information correspond to the second service type. If the first configuration information includes N first QoS information and the second configuration information includes M second QoS information, the N first QoS information corresponds to the first service type, and the M second QoS information corresponds to the second service type.

Optionally, in some embodiments, the first service type is a unicast service, and the second service type is any one or all of a multicast service and a broadcast service.

Optionally, in some embodiments, the first service type is unicast service, and the second service type is non-unicast service.

Optionally, in some embodiments, the first service type is an aperiodic service, and the second service type is a periodic service.

Optionally, in some embodiments, the first service type is a multicast service, and the second service type is a broadcast service.

Optionally, in some embodiments, the obtaining, by the first communication device, at least one of the first configuration information and the second configuration information includes: the first communication device acquires at least one of the first configuration information and the second configuration information configured in advance. In other words, the first configuration information and the second configuration information are pre-configured in the first communication device. The first communication device may acquire at least one of the first configuration information and the second configuration information configured in advance if the first communication device wishes to use a network resource based on the first configuration information and/or the second configuration information.

Optionally, in other embodiments, the obtaining, by the first communication device, at least one of the first configuration information and the second configuration information includes: the first communication device receives at least one of the first configuration information and the second configuration information sent by a network device.

The network device may determine the first configuration information and the second configuration information, and may transmit at least one of the determined first configuration information and second configuration information to the first communication device.

The first communications device may use resources according to the obtained configuration information 702.

The resource referred to in the embodiments of the present application may be at least one of a time domain resource, a frequency domain resource, or a spatial domain resource. For example, if the resource is a time domain resource, the time domain resource may be a combination of any one or more of a symbol (symbol), a slot (slot), a mini-slot (mini-slot), or a subframe (subframe). As another example, if the resource is a frequency domain resource, the resource may be any one or more of a Resource Element (RE), a Resource Block (RB), a Physical Resource Block (PRB), and a sub-channel (sub-channel). If the resource is a spatial domain resource, the resource may be a beam (beam) or an antenna port.

Optionally, in some embodiments, the first communications device may transmit information directly using the resource. The information referred to herein may be control information or data information. In other words, the first communication device may transmit control information and/or data information using the resources. In addition, the first communication device can directly use the resource to send information, which means that the resource is not occupied by other communication devices. Thus, the first communications device need not preempt resources before using the resources to transmit information. When the service type of the first communication device is the first service type, the first communication device may send first control information, where the first control information carries one of the N pieces of first reference information, and the first reference information carried in the first control information is reference information of the first communication device. In this way, the other communication device can determine whether the resource used by the first communication device can be occupied through the reference information in the first control information. When the service type of the first communication device is the second service type, the first communication device may send second control information, where the second control information carries one of the M pieces of second reference information, and the reference information carried in the second control information is the reference information of the first communication device. In this way, the other communication device can determine whether the resource used by the first communication device can be occupied through the reference information in the second control information. The specific implementation of the other communication device determining whether the resource used by the first communication device can be used can be found in the prior art or the above-mentioned embodiment. The first communication device may correspond to the second communication device in the embodiment shown in fig. 3 to 5, and the other communication device may correspond to the first communication device in the embodiment shown in fig. 3 to 5.

Optionally, in other embodiments, the first communication device may determine whether resources used by other communication devices (e.g., the second communication device) may be preempted according to the configuration information. Specifically, the second communication device may send control information when sending information using one resource (hereinafter, referred to as a target resource), and the reference information of the second communication device may be carried in the control information sent by the second communication device. The first communication device may determine whether the target resource may be used according to the reference information of the first communication device and the reference information of the second communication device in the received control information transmitted by the second communication device. If the service type of the first communication device is the first service type, the reference information of the first communication device is one of the N pieces of first reference information; if the service type of the first communication device is the second service type, the reference information of the first communication device is one of the M second reference information. In other words, in the case that the service type of the first communication device is the first service type, the first communication device may determine, according to one of the N first reference information and the received reference information transmitted by the second communication device, that the resource used by the second communication device is not used; in a case where the service type of the first communication device is the second service type, the first communication device may determine whether the resource used by the second communication device may be used according to one of the M pieces of second reference information and the received reference information transmitted by the second communication device. As described above, in some embodiments, the reference information may be priority information, and in other embodiments, the reference information may be QoS information. It will be appreciated that the type of reference information for the first communication device and the type of reference information for the second communication device should be the same. Specifically, if the reference information of the first communication device is priority information, the reference information of the second communication device is also priority information; if the reference information of the first communication device is QoS information, the reference information of the second communication device is also priority information. More specifically, if the reference information of the first communication device is PPPP, the reference information of the second communication device is also PPPP; if the QoS information of the first communication device is a QoS index, the QoS information of the second communication device is also a QoS index. The specific implementation manner of the first communication device determining whether the resource used by the second communication device can be used can be referred to in the prior art or the above-mentioned embodiment. The first communication device may correspond to the first communication device in the embodiment shown in fig. 3 to 5, and the second communication device may correspond to the second communication device in the embodiment shown in fig. 3 to 5.

Optionally, in some embodiments, the first configuration information corresponds to a first transmission mode, and the second configuration information corresponds to a second transmission mode. In other words, if the first configuration information includes N first priority information and the second configuration information includes M second priority information, the N first priority information corresponds to the first transmission mode and the M second priority information corresponds to the second transmission mode. If the first configuration information includes N first QoS information and the second configuration information includes M second QoS information, the N first QoS information corresponds to the first transmission mode and the M second QoS information corresponds to the second transmission mode.

Optionally, in some embodiments, the first transmission mode may be a base station scheduling mode, and the second transmission mode may be a mode in which resource selection is performed based on automatic sensing or automatic detection by the communication device.

Optionally, in some embodiments, the first communications device may transmit information directly using the resource. The information referred to herein may be control information or data information. In other words, the first communication device may transmit control information and/or data information using the resources. In addition, the first communication device can directly use the resource to send information, which means that the resource is not occupied by other communication devices. Thus, the first communications device need not preempt resources before using the resources to transmit information. When the transmission mode of the first communication device is the first transmission mode, the first communication device may send first control information, where the first control information carries one of the N pieces of first reference information, and the first reference information carried in the first control information is reference information of the first communication device. In this way, the other communication device can determine whether the resource used by the first communication device can be occupied through the reference information in the first control information. When the transmission mode of the first communication device is the second transmission mode, the first communication device may send second control information, where the second control information carries one of the M pieces of second reference information, and the reference information carried in the second control information is the reference information of the first communication device. In this way, the other communication device can determine whether the resource used by the first communication device can be occupied through the reference information in the second control information. The specific implementation of the other communication device determining whether the resource used by the first communication device can be used can be found in the prior art or the above-mentioned embodiment. The first communication device may correspond to the second communication device in the embodiment shown in fig. 6, and the other communication device may correspond to the first communication device in the embodiment shown in fig. 6.

Optionally, in other embodiments, the first communication device may determine whether resources used by other communication devices (e.g., the second communication device) may be preempted according to the configuration information. Specifically, the second communication device may send control information when sending information using one resource (hereinafter, referred to as a target resource), and the reference information of the second communication device may be carried in the control information sent by the second communication device. The first communication device may determine whether the target resource may be used according to the reference information of the first communication device and the reference information of the second communication device in the received control information transmitted by the second communication device. If the transmission mode of the first communication device is the first transmission mode, the reference information of the first communication device is one of the N first reference information; if the transmission mode of the first communication device is the second transmission mode, the reference information of the first communication device is one of the M second reference information. In other words, in a case where the transmission mode of the first communication device is the first transmission mode, the first communication device may determine not to use the resource used by the second communication device, based on one of the N pieces of first reference information and the received reference information transmitted by the second communication device; in a case where the transmission mode of the first communication device is the second transmission mode, the first communication device may determine whether the resource used by the second communication device can be used according to one of the M pieces of second reference information and the received reference information transmitted by the second communication device. As described above, in some embodiments, the reference information may be priority information, and in other embodiments, the reference information may be QoS information.
