Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure.

In order to better understand the sidelink-based communication method and device provided by the embodiments of the present disclosure, a description is first given below of a communication system to which the embodiments of the present disclosure are applicable.

The communication method based on the sidelink provided by the embodiment of the disclosure can be applied to the wireless communication system shown in fig. 1. Referring to fig. 1, the wireless communication system includes a network device and a terminal. The terminal is connected with the network equipment and/or other terminals through wireless resources and performs data transmission. Among them, the terminals can also carry out the sidelink communication based on the PC5 interface. It will be appreciated that the wireless communication system shown in fig. 1 is only schematically illustrated, and that other network devices may be included in the wireless communication system, for example, a core network device, a wireless relay device, a wireless backhaul device, etc., which are not shown in fig. 1. The number of network devices and the number of terminals included in the wireless communication system are not limited in the embodiments of the present disclosure.

It is further understood that the wireless communication system of the disclosed embodiments is a network that provides wireless communication functionality. The wireless communication system may employ different communication techniques such as code division multiple access (code division multiple access, CDMA), wideband code division multiple access (wideband code division multiple access, WCDMA), time division multiple access (time division multiple access, TDMA), frequency division multiple access (frequency division multiple access, FDMA), orthogonal frequency division multiple access (orthogonal frequency-division multiple access, OFDMA), single Carrier frequency division multiple access (SC-FDMA), carrier sense multiple access/collision avoidance (Carrier Sense MultipleAccess with CollisionAvoidance). Networks may be classified into 2G (english: generation) networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks, according to factors such as capacity, rate, delay, etc., and the 5G networks may also be referred to as New Radio (NR). For convenience of description, the present disclosure will sometimes refer to a wireless communication network simply as a network.

Further, the network devices referred to in this disclosure may also be referred to as radio access network devices. The radio access network device may be: a base station, an evolved node B (bs), a home base station, an Access Point (AP) in a wireless fidelity (wireless fidelity, WIFI) system, a wireless relay node, a wireless backhaul node, a transmission point (transmission point, TP), or a transmission reception point (transmission and receptionpoint, TRP), etc., may also be a gNB in an NR system, or may also be a component or a part of a device that forms a base station, etc. It should be understood that in the embodiments of the present disclosure, the specific technology and specific device configuration adopted by the network device are not limited. In the present disclosure, a network device may provide communication coverage for a particular geographic area and may communicate with terminals located within that coverage area (cell). In addition, in the case of a vehicle networking (V2X) communication system, the network device may also be an in-vehicle device.

Further, a Terminal referred to in the present disclosure may also be referred to as a Terminal device, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like, and may be a device that provides voice and/or data connectivity to a User, for example, a handheld device, an in-vehicle device, or the like that has a wireless connection function. Currently, some examples of terminals are: a smart Phone (Mobile Phone), a customer premise equipment (Customer Premise Equipment, CPE), a pocket computer (Pocket Personal Computer, PPC), a palm top computer, a personal digital assistant (Personal Digital Assistant, PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, in the case of a vehicle networking (V2X) communication system, the terminal device may also be an in-vehicle device. It should be understood that the embodiments of the present disclosure are not limited to the specific technology and specific device configuration adopted by the terminal.

The interfaces between the base station and the base station, and between the terminal and the base station can be specified by protocols such as LTE, NR, and the like, and the interfaces between the terminal and the terminal can be specified by a sidelink protocol so as to realize direct connection between the two terminals. As mentioned above, in NR, particularly when the communication band is in FR2, since the high frequency channel is attenuated faster, in order to secure the coverage, it is necessary to use beam-based transmission and reception. In order to achieve beam-based transmission, beam measurements are required. At least one of SSB and CSI-RS is mainly used in NR for beam measurement.

In the disclosed embodiment, the beams refer to beams, or spatial relationship information spatial relation information, spatial setting, spatial reception parameters Spatial Rx parameter, transmit spatial filter Tx spatial filter, spatial reception filter spatial domain receive filters, spatial transmit filter spatial domain transmission filter, transmit configuration indication (Transmission Configuration Indication, TCI) state, quasi co-location (Quasi Co Location, QCL) type D, and the like.

In the related art, there is no beam-based transmission in sidelink, and in order to introduce beam-based transmission, reference signals for beam measurement need to be designed. At this time, how to configure the reference signal resources for beam measurement is a problem to be solved.

In the related art, a channel state information configuration (sl-CSI-RS-Config) configured for a terminal includes a set of reference signal time domain start symbol position information (sl-CSI-RS-FirstSymbol) for determining a start symbol position and a set of reference signal frequency domain resource position (sl-CSI-RS-FreqAllocation) information for determining an RE position and a port number, corresponding to one CSI-RS resource. The configuration mode of the reference signal time domain start symbol position information is shown in table 1 below.

TABLE 1

Table 1 shows CSI-RS resource locations within one slot (slot). Wherein, row (row) 2 corresponds to 1 port of CSI-RS, and density (density) of 1 means that each physical resource block (PhysicalResourceBlock, PRB) has REs of CSI-RS resources. k (k) ₀ Refers to a Resource Element (RE) position in a PRB occupied by the CSI-RS, and one PRB contains 12 subcarriers REs. Furthermore, one PRB contains 14 symbols, and l ₀ And the symbol position is used for indicating the occupation of the CSI-RS resources. However, since for sidelink-based communications, the terminal needs to determine multiple sets of reference signal time domain start symbol position information and reference signal frequency domain resource position information to transmit multiple CSI-RS resources corresponding to different beam directions. In other words, for beam-based transmission in sidelink, the above-mentioned configuration of the channel state information resources cannot be directly multiplexed. Further, "a..+ -. To" referred to in table 1 means that there are other values, which are not listed here.

In view of this, the present disclosure provides a side link based communication method that clarifies the configuration of reference signal resources for beam measurement, providing an enhanced scheme for channel state information resource configuration. On the basis, the terminal can determine the reference signal resource allocation information for beam measurement, and further determine the reference signal resource information corresponding to the performing of the sidelink beam measurement through the reference signal resource allocation information.

In embodiments of the present disclosure, interaction between terminals may be involved. In order to facilitate distinguishing between different terminals, the disclosure refers to different terminals performing sidelink communication as a first device and a second device. Fig. 2 is a flow chart illustrating a side-link based communication method, as shown in fig. 2, performed by a first device, according to an exemplary embodiment, including the following steps.

In step S11, reference signal resource allocation information for beam measurement is determined.

In the embodiment of the disclosure, the reference signal resource configuration information is used for determining reference signal resource information corresponding to the first device performing the sidelink beam measurement.

The first device determines reference signal resource information based on the determined reference signal resource configuration information, determines reference signal resources for beam measurement based on the reference signal resource information, and then completes beam measurement based on the reference signal.

The reference signal may include, for example, at least one of side link channel state information (sidelink channel state information reference signal, sidelink CSI-RS) and side link synchronization signal blocks (sidelink-synchronization signal/physical broadcast channel Block, S-SS/PSBCH Block).

The method provided by the embodiment of the disclosure, the reference signal resource configuration information includes at least one of reference signal resource location information and a repetition (repetition) state corresponding to the reference signal resource set.

In an example, the reference signal resource information includes reference signal resource location information.

In another example, the reference signal resource information includes a repetition state corresponding to the reference signal resource set.

In another example, the reference signal resource information includes both reference signal resource location information and a repetition state corresponding to the reference signal resource set.

In the above embodiment, the reference signal resource set includes a plurality of reference signal resources, and the repetition status is used to indicate whether beams corresponding to the plurality of reference signal resources are the same.

For example, the repetition states corresponding to the reference signal resource sets include an on (on) state and an off (off) state. When the repetition state corresponding to the reference signal resource set is an on (on) state, each reference signal resource in the reference signal resource set corresponds to the same beam. When the repetition state corresponding to the reference signal resource set is an on (off) state, each reference signal resource in the reference signal resource set corresponds to a different beam.

The method provided by the embodiment of the disclosure, the reference signal resource position information can be understood as information related to the time-frequency resource position of the reference signal. The resource location information may include, for example, one or a combination of at least one time domain starting symbol location, at least one subcarrier location, at least one port number, a reference signal resource occupied slot number, a reference signal resource occupied small slot (mini-slot) number, a reference signal resource occupied time unit, a reference signal resource occupied starting resource block location, a reference signal resource occupied resource block number, a reference signal resource identification, and a reference signal resource set identification. The time unit occupied by the reference signal resource may be slot or mini-slot. Wherein, mini-slots are relative to slots as granularity. When scheduling is performed with slot as granularity, the minimum number of occupied symbols can be 3. When the mini-slot is used as granularity for scheduling, the minimum number of occupied symbols can be 1 or 2. And one slot can contain a plurality of scheduling units of mini-slots, and one mini-slot can occupy the symbols of two adjacent slots.

The method provided by the embodiment of the disclosure, the resource location information may include reference signal time domain start symbol location information (for example, sl-CSI-RS-FirstSymbol), and reference signal frequency domain resource location information (for example, sl-CSI-RS-FreqAllocation). The sl-CSI-RS-FirstSymbol is used for indicating a time domain starting symbol position corresponding to a reference signal resource, and the sl-CSI-RS-FreqAllocation is used for indicating an RE position and a port number corresponding to the reference signal resource.

In an embodiment of the present disclosure, the reference signal resource configuration information includes reference signal resource location information. In one embodiment, the sl-CSI-RS-FirstSymbol and the sl-CSI-RS-FreqAllocation may be configured by reference to signal resource location information. Also, as an example, the resource location information may include one or more sl-CSI-RS-first symbols, and one or more sl-CSI-RS-FreqAllocation.

In one embodiment, the resource location information includes a plurality of sl-CSI-RS-FirstSymbols and a plurality of sl-CSI-RS-FreqAllocations. The method comprises the steps that a plurality of sl-CSI-RS-first symbols are used for determining time domain initial symbol positions l corresponding to a plurality of reference signal resources respectively, and a plurality of sl-CSI-RS-FreqAllocations are used for determining RE positions and port numbers corresponding to the plurality of reference signal resources respectively.

The plurality of reference signal resources and the plurality of sl-CSI-RS-first symbols are in one-to-one correspondence, and the plurality of reference signal resources and the plurality of sl-CSI-RS-FreqAllocations are also in one-to-one correspondence. In this case, the sl-CSI-RS-first symbol and the sl-CSI-RS-FreqAllocation are independently allocated for each of the plurality of reference signal resources. That is, the time domain start symbol position, the RE position, and the port number are independently configured for each of the plurality of reference signal resources.

The method that the terminal determines the time domain starting symbol position through the sl-CSI-RS-first symbol can be applied to the case that one slot contains one CSI-RS resource or the case that one slot contains a plurality of CSI-RS resources. On the basis, in order to make the terminal further define the specific situation that the slot contains the CSI-RS resource, the resource position information can be used to indicate the situation that the slot contains the CSI-RS resource by an explicit indication mode or a default rule.

In an example, the slot position corresponding to each CSI-RS resource may be indicated by the resource position information, which is equivalent to the case that the resource indicates that the slot includes the CSI-RS resource in an explicit indication manner. On this basis, the resource location information may be used to determine slot locations corresponding to the plurality of reference signal resources, respectively, and the first device may determine a slot location corresponding to each CSI-RS resource based on the resource location information.

In another example, an indication of a time unit occupied by CSI-RS resources may be made through resource location information. For example, the resource location information may be used to indicate the number of slots occupied by multiple reference signal resources. On this basis, the resource location information may be used to determine the number of slots occupied by the plurality of reference signal resources, and the first device may determine the number of slots occupied by the plurality of reference signal resources based on the resource location information. In addition, the resource location information can also be used to indicate the mini-slot number occupied by multiple reference signal resources. On this basis, the resource location information may be used to determine the mini-slot number occupied by the plurality of reference signal resources, and the first device may determine the mini-slot number occupied by the plurality of reference signal resources based on the resource location information.

Wherein, different reference signal resources may correspond to the same or different slot positions.

For example, when the resource location information is used to determine slot locations corresponding to each of the plurality of reference signal resources, the time domain start symbol locations corresponding to different reference signal resources need to be different for reference signal resources corresponding to the same slot location. And for the reference signal resources corresponding to different slot positions, the time domain start symbol positions corresponding to different reference signal resources may be the same or different. For another example, when the resource location information is used to determine the slot number occupied by the plurality of reference signal resources, slots corresponding to different CSI-RS resources are different. For another example, when the resource location information is used to determine the number of mini-slots occupied by multiple reference signal resources, the resource location information indicates that the slots corresponding to different CSI-RS resources may be the same or different based on the transmission of the mini-slots.

The reference signal may be a sidelink CSI-RS according to the method provided by the embodiment of the present disclosure. Taking the sidelink CSI-RS as an example, we will simply refer to CSI-RS in the following. Each CSI-RS resource needs to occupy M symbol bits, and an automatic gain control (automatic gain control, AGC) adjustment needs to be configured before the CSI-RS resource, and one symbol bit for AGC needs to be additionally occupied before the symbol bit occupied by the CSI-RS resource. In other words, for configuration of one CSI-RS resource, m+1 symbol bits are required to be occupied. In addition, since one slot itself needs to reserve one symbol as a gap, when the configuration of one CSI-RS resource needs M symbol bits and m=1, and the number of symbol bits of the slot supporting configuration is N (N is a positive integer in the example), the number of CSI-RS resources of one slot configurable is N/2-1. For example, when slots support a configuration of 12 symbol bits, one slot may contain up to 5 CSI-RS resources. When slots support a configuration of 14 symbol bits, one slot may contain at most 6 CSI-RSs. When the symbol bit of one slot is occupied, and the subsequent CSI-RS resource configuration is configured, the next slot in the continuous slots is occupied continuously.

In one embodiment, the resource location information includes a plurality of sl-CSI-RS-FirstSymbols and a single sl-CSI-RS-FreqAllocation. The method comprises the steps that a plurality of sl-CSI-RS-first symbols are used for determining time domain initial symbol positions corresponding to a plurality of reference signal resources respectively, and a single sl-CSI-RS-FreqAllocation is used for determining RE positions and port numbers corresponding to the plurality of reference signal resources.

Wherein, the plurality of reference signal resources and the plurality of sl-CSI-RS-first symbols are in one-to-one correspondence. In this case, the sl-CSI-RS-first symbol is configured independently for each of the plurality of reference signal resources, and the time domain start symbol positions may be the same or different from each other. In addition, the resource location information further includes a single sl-CSI-RS-FreqAllocation for determining the locations and port numbers of the REs corresponding to the plurality of reference signal resources, where the single sl-CSI-RS-FreqAllocation may be understood as an sl-CSI-RS-FreqAllocation shared by the plurality of reference signal resources. In other words, the multiple reference signal resources each correspond to the same sl-CSI-RS-FreqAllocation. In this case, the RE position and the port number corresponding to each reference signal resource are the same.

The method that the terminal determines the time domain starting symbol position through the sl-CSI-RS-first symbol can be applied to the case that one slot contains one CSI-RS resource or the case that one slot contains a plurality of CSI-RS resources. On the basis, in order to make the terminal further define the specific situation that the slot contains the CSI-RS resource, the resource position information can be used to indicate the situation that the slot contains the CSI-RS resource by an explicit indication mode or a default rule. The implementation manner of indicating the time unit occupied by the CSI-RS resource through the resource location information has been described in the foregoing embodiments of the present disclosure, and therefore, the specific implementation manner may directly refer to the foregoing embodiments, and the disclosure is not repeated herein.

In one embodiment, the resource location information includes a single sl-CSI-RS-first symbol and a plurality of sl-CSI-RS-freqallocations. The single sl-CSI-RS-first symbol is used for determining time domain initial symbol positions corresponding to a plurality of reference signal resources, and the plurality of sl-CSI-RS-FreqAllocations are used for determining RE positions and port numbers corresponding to the plurality of reference signal resources respectively.

For example, the resource location information includes a single sl-CSI-RS-FirstSymbol and a plurality of sl-CSI-RS-freqallocations. Wherein different ones of the plurality of reference signal resources correspond to the same time domain starting symbol position. The plurality of reference signal resources and the plurality of sl-CSI-RS-FreqAllocation are in one-to-one correspondence, which is equivalent to that the sl-CSI-RS-FreqAllocation is respectively and independently configured for each reference signal resource in the plurality of reference signal resources. That is, the RE position and the port number are independently configured for each of the plurality of reference signal resources. At this time, different CSI-RS resources correspond to different slots, but to the same time domain start symbol position. And, the RE positions and port numbers corresponding to different CSI-RS resources may be the same or different.

For example, the resource location information includes a single sl-CSI-RS-first symbol and a plurality of sl-CSI-RS-freqallocations, and includes a slot number and/or a reference signal resource number. Wherein different ones of the plurality of reference signal resources correspond to the same time domain starting symbol position. The plurality of reference signal resources and the plurality of sl-CSI-RS-FreqAllocation are in one-to-one correspondence, which is equivalent to that the sl-CSI-RS-FreqAllocation is respectively and independently configured for each reference signal resource in the plurality of reference signal resources. That is, the RE position and the port number are independently configured for each of the plurality of reference signal resources. At this time, different CSI-RS resources correspond to different slots, but to the same time domain start symbol position. And, the RE positions and port numbers corresponding to different CSI-RS resources may be the same or different.

For another example, the resource location information includes a single sl-CSI-RS-FirstSymbol and a plurality of sl-CSI-RS-freqallocations. The multiple reference signal resources and the multiple sl-CSI-RS-FreqAllocations are in one-to-one correspondence, which is equivalent to that the sl-CSI-RS-FreqAllocations are respectively and independently configured for each of the multiple reference signal resources. That is, for each of the plurality of reference signal resources, the RE position and the port number are configured independently, and the RE position and the port number corresponding to different CSI-RS resources may be the same or different. And the time domain initial symbol positions corresponding to different reference signal resources in the plurality of reference signal resources are symbol positions corresponding to the first mini-slot, a set number of symbol intervals are arranged between adjacent mini-slots in the plurality of mini-slots, and the different reference signal resources correspond to the same or different RE positions and port numbers.

For another example, the resource location information includes a single sl-CSI-RS-first symbol and a plurality of sl-CSI-RS-freqallocations, and includes a mini-slot number and/or a reference signal resource number. The multiple reference signal resources and the multiple sl-CSI-RS-FreqAllocations are in one-to-one correspondence, which is equivalent to that the sl-CSI-RS-FreqAllocations are respectively and independently configured for each of the multiple reference signal resources. That is, for each of the plurality of reference signal resources, the RE position and the port number are configured independently, and the RE position and the port number corresponding to different CSI-RS resources may be the same or different. And the time domain initial symbol positions corresponding to different reference signal resources in the plurality of reference signal resources are symbol positions corresponding to the first mini-slot, a set number of symbol intervals are arranged between adjacent mini-slots in the plurality of mini-slots, and the different reference signal resources correspond to the same or different RE positions and port numbers.

By way of example, the reference signal may be a sidelink CSI-RS. Taking the sidelink CSI-RS as an example, the following is abbreviated as CSI-RS. Each CSI-RS resource needs to occupy M symbol bits, and an automatic gain control (automatic gain control, AGC) adjustment needs to be configured before the CSI-RS resource, and one symbol bit for AGC needs to be additionally occupied before the symbol bit occupied by the CSI-RS resource. In other words, for configuration of one CSI-RS resource, m+1 symbol bits are required to be occupied. In addition, since a slot itself needs to reserve a symbol as a gap, when the configuration of one CSI-RS resource needs to occupy m+1 symbol bits and m=1, and the number of symbol bits of the slot supporting configuration is N (N is a positive integer in the example), the number of CSI-RS resources of one slot configurable is N/2-1. For example, when slots support a configuration of 12 symbol bits, one slot may contain up to 5 CSI-RS resources. When slots support a configuration of 14 symbol bits, one slot may contain up to 6 CSI-RS resources. When the symbol bit of one slot is occupied, and the subsequent CSI-RS resource configuration is configured, the next slot in the continuous slots is occupied continuously.

Of course, the reference signal resources occupy one symbol bit is only a possible embodiment, and the number of symbols actually occupied by the reference signal resources is not limited thereto. Accordingly, for a slot, the number of configuration of the supportable reference signal resources may be adjusted accordingly by the number of symbols actually occupied by the reference signal resources and the number of symbols limitation of the slot itself (for example, the number of symbols limitation may be understood as a factor affecting the number of configuration of the reference signal resources, for example, may be the reserved gap bit referred to above).

In addition, for the case that the resource location information includes a single sl-CSI-RS-first symbol, a plurality of sl-CSI-RS-FreqAllocation, and a mini-slot number and/or a reference signal resource number, the time domain start position of the first mini-slot may be determined by the sl-CSI-RS-first symbol, and the time domain start position of the subsequent mini-slot may be sequentially determined based on the time domain start position of the first mini-slot. For example, the time domain start position of the second mini-slot is determined based on the time domain end position of the first mini-slot. The time domain starting position of the third mini-slot is determined based on the time domain ending position of the second mini-slot. Taking the time domain end position of the first mini-slot as an example, determining the time domain start position of the second mini-slot, wherein the time domain end position of the first mini-slot and the time domain start position of the second mini-slot are separated by symbols occupied by AGC, and the number of symbols occupied by AGC is added on the basis of the time domain end position of the first mini-slot, so that the time domain start position of the second mini-slot can be obtained.

In an embodiment, the resource location information includes a single sl-CSI-RS-first symbol and a single sl-CSI-RS-FreqAllocation, and includes a slot number and/or a reference signal resource number.

The single sl-CSI-RS-first symbol is used for determining time domain starting symbol positions corresponding to a plurality of reference signal resources, and the single sl-CSI-RS-FreqAllocation is used for determining RE positions and port numbers corresponding to the plurality of reference signal resources.

Wherein, different reference signal resources in the plurality of reference signal resources correspond to the same time domain starting symbol position, and reference signal resources in the same slot correspond to the same RE position and port number. In other words, the resource location information includes a single sl-CSI-RS-FirstSymbol for determining the time domain start symbol locations corresponding to the plurality of reference signal resources, and includes a single sl-CSI-RS-FreqAllocation for determining the RE locations and the port numbers corresponding to the plurality of reference signal resources, and includes the number of slots and/or the number of reference signals. The slots are kept continuous or discontinuous, and the quantity of the CSI-RS resources is consistent with the quantity of the slots. At this time, different CSI-RS resources correspond to different slots, but different CSI-RS resources correspond to the same time domain start symbol position, the same RE position, and the same port number.

According to the method provided by the embodiment of the disclosure, when the resource location information comprises single slot-CSI-RS-first symbol, single slot-CSI-RS-FreqAllocation, the number of slots and/or the number of reference signal resources, the resource location information is suitable for slot-based configuration.

In an embodiment, the resource location information includes a single sl-CSI-RS-first symbol and a single sl-CSI-RS-FreqAllocation, and includes a mini-slot number and/or a reference signal resource number.

The time domain initial symbol positions corresponding to different reference signal resources in the plurality of reference signal resources are symbol positions corresponding to a first mini-slot, a set number of symbol intervals are arranged between adjacent mini-slots in the plurality of mini-slots, and different reference signal resources correspond to the same RE positions and port numbers.

In addition, for the case that the resource location information includes a single sl-CSI-RS-first symbol, a single sl-CSI-RS-FreqAllocation, and the number of mini-slots and/or the number of reference signal resources, the time domain start position of the first mini-slot may be determined by the sl-CSI-RS-first symbol, and the time domain start position of the subsequent mini-slot may be sequentially determined based on the time domain start position of the first mini-slot. For example, the time domain start position of the second mini-slot is determined based on the time domain end position of the first mini-slot. The time domain starting position of the third mini-slot is determined based on the time domain ending position of the second mini-slot. Taking the time domain end position of the first mini-slot as an example, determining the time domain start position of the second mini-slot, wherein the time domain end position of the first mini-slot and the time domain start position of the second mini-slot are separated by symbols occupied by AGC, and the number of symbols occupied by AGC is added on the basis of the time domain end position of the first mini-slot, so that the time domain start position of the second mini-slot can be obtained.

According to the method provided by the embodiment of the disclosure, when the resource location information comprises single sl-CSI-RS-first symbol, single sl-CSI-RS-FreqAllocation, the number of mini-slots and/or the number of reference signal resources, the resource location information is suitable for mini-slot-based configuration.

The method provided by the embodiments of the present disclosure, based on the foregoing embodiments, may include one or more reference signal resources in the same slot.

For convenience of description, other terminals different from the first device will be referred to as second devices, and reference signal resource configuration information transmitted by the network device for determining the beam measurement will be referred to as first configuration information. And reference signal resource configuration information for beam measurement transmitted by the second device is referred to as second configuration information.

In step S21, first configuration information sent by the network device is received.

In step S22, reference signal resource configuration information is determined based on the first configuration information.

The first configuration information may be carried by radio resource control (Radio Resource Control, RRC) signaling between the network device and the first terminal device, for example.

Fig. 4 is a flowchart illustrating a method for determining reference signal resource configuration information based on a second device, as shown in fig. 4, according to an exemplary embodiment, including the following steps.

In step S31, second configuration information transmitted by the second device is received.

In step S32, reference signal resource configuration information is determined based on the second configuration information.

The first and second modes can be understood as the configuration of the reference signal resource configuration information completed through the transmission of the configuration information, and the third mode can be understood as the pre-configuration of the reference signal resource configuration information through a mode specified by a protocol.

The second configuration information may be carried, for example, by PC5 RRC for interaction between terminals. The second configuration information may also be carried, for example, over a physical side link shared channel (Physical Sidelink Shared Channel, PSSCH) for use between terminals, such as through a SL MAC CE over the PSSCH. The second configuration information may also be carried, for example, over a physical side link control channel (Physical Sidelink Control Channel, PSCCH) for use between terminals, for example, over a sidelink control information SCI on the PSCCH.

In addition, in a possible embodiment of the present disclosure, the reference signal Resource configuration information may further include at least one of a Resource Block (RB) position and a bandwidth configuration. Among them, for the initial resource block position and bandwidth configuration, the available configuration modes include an explicit configuration mode and a default configuration mode. Taking the default configuration as an example, the starting resource block location and/or bandwidth configuration may be configured by default to coincide with the starting RB location and bandwidth of the specified PSSCH. The designated PSSCH may be, for example, the last transmitted PSSCH. Or the designated PSSCH may be a PSSCH corresponding to a time domain resource and a frequency domain resource indicated in the SCI where the beam measurement request is located, where the time domain resource and the frequency domain resource may be directly indicated in the SCI or may be indicated by a reserved resource included in the SCI. I.e. the SCI corresponding to the beam measurement request is identical to the SCI corresponding to the PSSCH resource indication, wherein the SCI may be a first stage SCI and/or a second stage SCI.

The reference signal includes at least one of side link channel state information and a side link synchronization signal block, for example.

Based on the same technical concept, the present disclosure also proposes a side link-based communication method, which is executed by a network device, and completes configuration of reference signal resource configuration information of a first device through interaction with the first device. If there is an ambiguity in the embodiments described below, reference can be made to any of the embodiments described above.

Fig. 5 is a flowchart illustrating a side-link based communication method, as shown in fig. 5, performed by a network device, according to an exemplary embodiment, including the following steps.

In step S41, first configuration information is transmitted.

In the embodiment of the disclosure, the first configuration information is reference signal resource configuration information sent by the network device and used for enabling the first device to determine the reference signal resource configuration information used for beam measurement, and the reference signal resource configuration information is used for determining reference signal resource information corresponding to the first device performing the sidelink beam measurement. The network device sends the first configuration information to enable the terminal to acquire the reference signal resource configuration information through the first configuration information, and determines the reference signal resource information corresponding to the sidelink beam measurement through the reference signal resource configuration information.

The method provided by the embodiment of the disclosure, the reference signal resource configuration information includes at least one of reference signal resource position information and a repetition state corresponding to the reference signal resource set.

For example, the repetition states corresponding to the reference signal resource sets include an on (on) state and an off (off) state. When the repetition state corresponding to the reference signal resource set is an on (on) state, each reference signal in the reference signal resource set corresponds to the same beam. When the repetition state corresponding to the reference signal resource set is an on (off) state, each reference signal in the reference signal resource set corresponds to a different beam.

The method provided by the embodiment of the disclosure, the reference signal resource position information can be understood as information related to the time-frequency resource position of the reference signal. The resource location information may include, for example, one or a combination of at least one time domain starting symbol location, at least one subcarrier location, at least one port number, a reference signal resource occupied slot number, a reference signal resource occupied mini-slot number, a reference signal resource occupied time unit reference signal resource occupied starting resource block location, a reference signal resource occupied resource block number, a reference signal resource identification, and a reference signal resource set identification. The time unit occupied by the reference signal resource may be slot or mini-slot.

Wherein, mini-slots are relative to slots as granularity. When scheduling is performed with slot as granularity, the minimum number of occupied symbols can be 3. When the mini-slot is used as granularity for scheduling, the minimum number of occupied symbols can be 1 or 2. And one slot can contain a plurality of scheduling units of mini-slots, and one mini-slot can occupy the symbols of two adjacent slots.

The method provided by the embodiment of the disclosure, the resource location information may include reference signal time domain start symbol location information (for example, sl-CSI-RS-FirstSymbol), and reference signal frequency domain resource location information (for example, sl-CSI-RS-FreqAllocation). The sl-CSI-RS-FirstSymbol is used for determining a time domain starting symbol position corresponding to a reference signal resource, and the sl-CSI-RS-FreqAllocation is used for determining an RE position and a port number corresponding to the reference signal resource.

In one embodiment, the resource location information includes a plurality of sl-CSI-RS-FirstSymbols and a plurality of sl-CSI-RS-FreqAllocations. The method comprises the steps that a plurality of sl-CSI-RS-first symbols are used for determining time domain initial symbol positions corresponding to a plurality of reference signal resources respectively, and a plurality of sl-CSI-RS-FreqAllocations are used for determining RE positions and port numbers corresponding to the plurality of reference signal resources respectively.

By way of example, the method of determining the time domain start symbol position by the slot-CSI-RS-first symbol may be applicable to a case where one slot contains one CSI-RS resource, or may be applicable to a case where one slot contains multiple CSI-RS resources. On the basis, in order to make the terminal further define the specific situation that the slot contains the CSI-RS resource, the network device can further use the resource position information to indicate the situation that the slot contains the CSI-RS resource through an explicit indication mode or a default rule.

In an example, the slot position corresponding to each CSI-RS resource may be indicated by the resource position information, which is equivalent to the case that the resource indicates that the slot includes the CSI-RS resource in an explicit indication manner. On this basis, the resource location information may be used to indicate slot locations corresponding to the multiple reference signal resources respectively, and the first device may determine a slot location corresponding to each CSI-RS resource based on the resource location information.

In another example, an indication of a time unit occupied by CSI-RS resources may be made through resource location information. For example, the resource location information may be used to indicate the number of slots occupied by multiple reference signal resources. On this basis, the resource location information may be used to indicate the number of slots occupied by the plurality of reference signal resources, and the first device may determine the number of slots occupied by the plurality of reference signal resources based on the resource location information. In addition, the resource location information can also be used to indicate the mini-slot number occupied by multiple reference signal resources. On this basis, the resource location information may be used to indicate the mini-slot number occupied by the plurality of reference signal resources, and the first device may determine the mini-slot number occupied by the plurality of reference signal resources based on the resource location information.

For example, when the resource location information is used to indicate slot locations corresponding to each of the plurality of reference signal resources, the time domain start symbol locations corresponding to different reference signal resources need to be different for reference signal resources corresponding to the same slot location. And for the reference signal resources corresponding to different slot positions, the time domain start symbol positions corresponding to different reference signal resources may be the same or different. For another example, when the resource location information is used to indicate the slot number occupied by the plurality of reference signal resources, the slot locations corresponding to different CSI-RS resources are different. For another example, when the resource location information is used to indicate the number of mini-slots occupied by the multiple reference signal resources, the resource location information indicates that the slot locations corresponding to different CSI-RS resources may be the same or different based on the transmission of the mini-slots.

The reference signal may be a sidelink CSI-RS according to the method provided by the embodiment of the present disclosure. Taking the sidelink CSI-RS as an example, we will simply refer to CSI-RS in the following. Each CSI-RS resource needs to occupy M symbol bits, and AGC adjustment is needed before the CSI-RS resource, and one symbol bit for AGC needs to be additionally occupied before the symbol bit occupied by the CSI-RS resource. In other words, for configuration of one CSI-RS resource, m+1 symbol bits are required to be occupied. In addition, since one slot itself needs to reserve one symbol as a gap, when the configuration of one CSI-RS resource needs M symbol bits and m=1, and the number of symbol bits of the slot supporting configuration is N (N is a positive integer in the example), the number of CSI-RS resources of one slot configurable is N/2-1. For example, when slots support a configuration of 12 symbol bits, one slot may contain up to 5 CSI-RS resources. When slots support a configuration of 14 symbol bits, one slot may contain at most 6 CSI-RSs. When the symbol bit of one slot is occupied, and the subsequent CSI-RS resource configuration is configured, the next slot in the continuous slots is occupied continuously.

The method of determining the time domain starting symbol position through the sl-CSI-RS-first symbol can be applied to a case where one slot contains one CSI-RS resource, or can be applied to a case where one slot contains multiple CSI-RS resources. On the basis, in order to make the terminal further define the specific situation that the slot contains the CSI-RS resource, the resource position information can be used to indicate the situation that the slot contains the CSI-RS resource by an explicit indication mode or a default rule. The implementation manner of determining the time unit occupied by the CSI-RS resource through the resource location information has been described in the foregoing embodiments of the present disclosure, and therefore, the specific implementation manner may directly refer to the foregoing embodiments, and the disclosure is not repeated herein.

In one embodiment, the resource location information includes a single sl-CSI-RS-first symbol and a plurality of sl-CSI-RS-freqallocations. The single sl-CSI-RS-first symbol is used for determining the time domain initial symbol positions corresponding to the multiple reference signal resources, and the multiple sl-CSI-RS-FreqAllocation is used for determining RE positions and port numbers corresponding to the multiple reference signal resources respectively.

By way of example, the reference signal may be a sidelink CSI-RS. Taking the sidelink CSI-RS as an example, the following is abbreviated as CSI-RS. Each CSI-RS resource needs to occupy M symbol bits, and AGC adjustment needs to be configured before the CSI-RS resource, and one symbol bit for AGC needs to be additionally occupied before the symbol bit occupied by the CSI-RS resource. In other words, for configuration of one CSI-RS resource, m+1 symbol bits are required to be occupied. In addition, since a slot itself needs to reserve a symbol as a gap, when the configuration of one CSI-RS resource needs to occupy m+1 symbol bits and m=1, and the number of symbol bits of the slot supporting configuration is N (N is a positive integer in the example), the number of CSI-RS resources of one slot configurable is N/2-1. For example, when slots support a configuration of 12 symbol bits, one slot may contain up to 5 CSI-RS resources. When slots support a configuration of 14 symbol bits, one slot may contain up to 6 CSI-RS resources. When the symbol bit of one slot is occupied, and the subsequent CSI-RS resource configuration is configured, the next slot in the continuous slots is occupied continuously.

In addition, in a possible embodiment of the present disclosure, the reference signal resource configuration information may further include at least one of a starting RB location and a bandwidth configuration. Among them, for the initial resource block position and bandwidth configuration, the available configuration modes include an explicit configuration mode and a default configuration mode. Taking the default configuration as an example, the starting resource block location and/or bandwidth configuration may be configured by default to coincide with the starting RB location and bandwidth of the specified PSSCH. The designated PSSCH may be, for example, the last transmitted PSSCH. Or the designated PSSCH may be a PSSCH corresponding to a time domain resource and a frequency domain resource indicated in the SCI where the beam measurement request is located, where the time domain resource and the frequency domain resource may be directly indicated in the SCI or may be indicated by a reserved resource in the SCI. I.e. the SCI corresponding to the beam measurement request is identical to the SCI corresponding to the PSSCH resource indication, wherein the SCI may be a first stage SCI and/or a second stage SCI.

It may be understood that the technical implementation involved in the process of performing the sidelink-based communication by the network device in the embodiment of the present disclosure may be applicable to the process of performing the sidelink-based communication by the first device in the embodiment of the present disclosure, so some technical implementation descriptions of the process of performing the sidelink-based communication by the network device may be referred to for details of the process of performing the sidelink-based communication by the first device, which are not described herein.

Based on the same technical concept, the present disclosure also proposes a side link-based communication method, which is performed by a second device, and completes configuration of reference signal resource configuration information of the first device through interaction with the first device. If there is an ambiguity in the embodiments described below, reference can be made to any of the embodiments described above.

Fig. 6 is a flowchart illustrating a side-link based communication method, as shown in fig. 6, performed by a second device, according to an exemplary embodiment, including the following steps.

In step S51, the second configuration information is transmitted.

In the embodiment of the disclosure, the second configuration information is reference signal resource configuration information sent by the second device and used for enabling the first device to determine the reference signal resource configuration information used for beam measurement, and the reference signal resource configuration information is used for determining reference signal resource information corresponding to the first device performing sidelink beam measurement. The network device sends the first configuration information to enable the terminal to acquire the reference signal resource configuration information through the first configuration information, and determines the reference signal resource information corresponding to the sidelink beam measurement through the reference signal resource configuration information.

The second configuration information may be carried, for example, by PC5 RRC for interaction between terminals. The second configuration information may also be carried, for example, through a PSSCH for use between terminals, such as through a SL MAC CE on the PSSCH. The second configuration information may also be carried, for example, by a physical side link control channel PSCCH for use between terminals, for example by a sidelink control information SCI on the PSCCH.

The method provided by the embodiment of the present disclosure, the resource location information may be understood as information related to the time-frequency resource location of the reference signal. The resource location information may include, for example, one or a combination of at least one time domain starting symbol location, at least one subcarrier location, at least one port number, a reference signal resource occupied slot number, a reference signal resource occupied mini-slot number, a reference signal resource occupied time unit reference signal resource occupied starting resource block location, a reference signal resource occupied resource block number, a reference signal resource identification, and a reference signal resource set identification. The time unit occupied by the reference signal resource may be slot or mini-slot.

By way of example, the method of determining the time domain start symbol position by the slot-CSI-RS-first symbol may be applicable to a case where one slot contains one CSI-RS resource, or may be applicable to a case where one slot contains multiple CSI-RS resources. On the basis, in order to make the terminal further define the specific situation that the slot contains the CSI-RS resource, the second device can further use the resource position information to indicate the situation that the slot contains the CSI-RS resource through an explicit indication mode or a default rule.

In an example, the slot position corresponding to each CSI-RS resource may be determined through the resource position information, which is equivalent to the resource indicating the case that the slot contains the CSI-RS resource in an explicit indication manner. On this basis, the resource location information may be used to determine slot locations corresponding to the plurality of reference signal resources, respectively, and the first device may determine a slot location corresponding to each CSI-RS resource based on the resource location information.

In another example, an indication of a time unit occupied by CSI-RS resources may be made through resource location information. For example, the resource location information may be used to indicate a number of slots occupied by the plurality of reference signal resources, and the first device may determine the number of slots occupied by the plurality of reference signal resources based on the resource location information. In addition, the resource location information may be further used to indicate a mini-slot number occupied by the plurality of reference signal resources, and the first device may determine the mini-slot number occupied by the plurality of reference signal resources based on the resource location information.

For example, when the resource location information is used to determine slot locations corresponding to each of the plurality of reference signal resources, the time domain start symbol locations corresponding to different reference signal resources need to be different for reference signal resources corresponding to the same slot location. And for the reference signal resources corresponding to different slot positions, the time domain start symbol positions corresponding to different reference signal resources may be the same or different. For another example, when the resource location information is used to determine the slot number occupied by the plurality of reference signal resources, the slot locations corresponding to different CSI-RS resources are different. For another example, when the resource location information is used to determine the number of mini-slots occupied by the plurality of reference signal resources, the resource location information indicates that the slot locations corresponding to different CSI-RS resources may be the same or different based on the transmission of the mini-slots.

The reference signal may be a sidelink CSI-RS according to the method provided by the embodiment of the present disclosure. Taking the sidelink CSI-RS as an example, we will simply refer to CSI-RS in the following. Each CSI-RS resource needs to occupy M symbol bits, and AGC adjustment needs to be configured before the CSI-RS resource, and one symbol bit for AGC needs to be additionally occupied before the symbol bit occupied by the CSI-RS resource. In other words, for configuration of one CSI-RS resource, m+1 symbol bits are required to be occupied. In addition, since one slot itself needs to reserve one symbol as a gap, when the configuration of one CSI-RS resource needs M symbol bits and m=1, and the number of symbol bits of the slot supporting configuration is N (N is a positive integer in the example), the number of CSI-RS resources of one slot configurable is N/2-1. For example, when slots support a configuration of 12 symbol bits, one slot may contain up to 5 CSI-RS resources. When slots support a configuration of 14 symbol bits, one slot may contain at most 6 CSI-RSs. When the symbol bit of one slot is occupied, and the subsequent CSI-RS resource configuration is configured, the next slot in the continuous slots is occupied continuously.

The method of determining the time domain starting symbol position through the sl-CSI-RS-first symbol can be applied to a case where one slot contains one CSI-RS resource, or can be applied to a case where one slot contains multiple CSI-RS resources. On the basis, in order to make the terminal further define the specific situation that the slot contains the CSI-RS resource, the resource position information can be used to indicate the situation that the slot contains the CSI-RS resource by an explicit indication mode or a default rule. The implementation manner of indicating the time unit occupied by the CSI-RS resource through the resource location information has been described in the foregoing embodiments of the present disclosure, and therefore, the specific implementation manner may directly refer to the foregoing embodiments, and the disclosure is not repeated herein.

For example, the resource location information includes a single sl-CSI-RS-first symbol and a plurality of sl-CSI-RS-freqallocations, and includes a slot number and/or a reference signal resource number. Wherein different ones of the plurality of reference signal resources correspond to the same time domain starting symbol position. The multiple reference signal resources and the multiple sl-CSI-RS-FreqAllocations are in one-to-one correspondence, which is equivalent to that the sl-CSI-RS-FreqAllocation is respectively and independently configured for each reference signal resource in the multiple reference signal resources. That is, the RE position and the port number are independently configured for each of the plurality of reference signal resources. At this time, different CSI-RS resources correspond to different slots, but to the same time domain start symbol position. And, the RE positions and port numbers corresponding to different CSI-RS resources may be the same or different.

For another example, the resource location information includes a single sl-CSI-RS-first symbol and a plurality of sl-CSI-RS-freqallocations, and includes a mini-slot number and/or a reference signal resource number. The multiple reference signal resources and the multiple sl-CSI-RS-FreqAllocation are in one-to-one correspondence, which is equivalent to that the sl-CSI-RS-FreqAllocation is respectively and independently configured for each reference signal resource in the multiple reference signal resources. That is, for each of the plurality of reference signal resources, the RE position and the port number are configured independently, and the RE position and the port number corresponding to different CSI-RS resources may be the same or different. And the time domain initial symbol positions corresponding to different reference signal resources in the plurality of reference signal resources are symbol positions corresponding to the first mini-slot, a set number of symbol intervals are arranged between adjacent mini-slots in the plurality of mini-slots, and the different reference signal resources correspond to the same or different RE positions and port numbers.

In addition, for the case that the resource location information includes a single sl-CSI-RS-first symbol, and the number of mini-slots and/or the number of reference signal resources, the time domain start position of the first mini-slot may be determined by the sl-CSI-RS-first symbol, and the time domain start position of the subsequent mini-slot may be sequentially determined based on the time domain start position of the first mini-slot. For example, the time domain start position of the second mini-slot is determined based on the time domain end position of the first mini-slot. The time domain starting position of the third mini-slot is determined based on the time domain ending position of the second mini-slot. Taking the time domain end position of the first mini-slot as an example, determining the time domain start position of the second mini-slot, wherein the time domain end position of the first mini-slot and the time domain start position of the second mini-slot are separated by symbols occupied by AGC, and the number of symbols occupied by AGC is added on the basis of the time domain end position of the first mini-slot, so that the time domain start position of the second mini-slot can be obtained.

In addition, in a possible embodiment of the present disclosure, the reference signal resource configuration information may further include at least one of a starting RB location and a bandwidth configuration. Among them, for the initial resource block position and bandwidth configuration, the available configuration modes include an explicit configuration mode and a default configuration mode. Taking the default configuration as an example, the starting resource block location and/or bandwidth configuration may be configured by default to coincide with the starting RB location and bandwidth of the specified PSSCH. The designated PSSCH may be, for example, the last transmitted PSSCH. Or the specified PSSCH may be a PSSCH corresponding to the time domain resource and the frequency domain resource indicated in the SCI where the beam measurement request is located, i.e., the SCI corresponding to the beam measurement request is the same as the SCI corresponding to the PSSCH resource indication, where the SCI may be a first stage SCI and/or a second stage SCI.

It may be understood that the technical implementation involved in the process of performing the sidelink-based communication by the second device in the embodiment of the present disclosure may be applicable to the process of performing the sidelink-based communication by the first device in the embodiment of the present disclosure, so some technical implementation descriptions of the process of performing the sidelink-based communication by the second device may be referred to the relevant descriptions in the process of performing the sidelink-based communication by the first device, which are not described herein.
