[0136] In the embodiments of the present application, the term "and / or" describes the association relationship of the associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0137] In the embodiments of the present application, the term "plurality" refers to two or more than two, and other quantifiers are similar.

[0138] In the embodiments of the present application, the terms "first", "second", etc. are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0139] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0140] Figure 1A schematic diagram of a resource determination method provided in an embodiment of the present application, which can be applied to a terminal, such as Figure 1 As shown, the method comprises the following steps:

[0141] Step 100: Determine target control channel resources and / or target SL PRS resources based on the association relationship between control channel resources and direct link positioning reference signal SL PRS resources in a resource pool.

[0142] Specifically, the resource pool in the present application may be a dedicated resource pool for SL positioning. The dedicated resource pool for positioning only includes control channel resources and SL PRS resources, and the control channel resources are used to transmit sidelink control information (SCI).

[0143] The control channel resources may include physical sidelink control channel (PSCCH) resources and / or SCI resources. In some embodiments, the SCI resources may be PSCCH resources.

[0144] The resource pool may include control channel resources and SL PRS resources. There is a certain association relationship (or mapping relationship) between the control channel resources and the SL PRS resources, so that the terminal can determine the target control channel resources and / or target SL PRS resources based on the association relationship between the control channel resources and the SLPRS resources in the resource pool.

[0145] The target control channel resource may be any control channel resource, or a control channel resource associated with a certain (or some) SL PRS resource / SL PRS resource set.

[0146] The target SL PRS resource may be any SL PRS resource, or a SL PRS resource associated with a certain (or some) control channel resources.

[0147] In some embodiments, the terminal may determine the SL PRS resources associated with the known control channel resources based on the association relationship between the control channel resources in the resource pool and the SL PRS resources when the control channel resources are known; or, the terminal may determine the control channel resources associated with the known SL PRS resources based on the association relationship between the control channel resources in the resource pool and the SL PRS resources when the SL PRS resources are known; or, the terminal may determine the associated control channel resources and SL PRS resources based on the association relationship between the control channel resources in the resource pool and the SL PRS resources.

[0148] For example, assuming that the terminal detects SCI on a certain PSCCH resource, the terminal can determine the SL PRS resource associated with the PSCCH resource or the SCI based on the association relationship between the control channel resources and the SL PRS resources in the resource pool.

[0149] For example, assuming that a certain SL PRS resource is indicated in the resource allocation indication received by the terminal, the terminal can determine the PSCCH resource associated with the SL PRS resource based on the association relationship between the control channel resources in the resource pool and the SL PRS resources, and use the PSCCH resource to send SCI to other terminals to indicate the SL PRS resource.

[0150] For example, the terminal may determine associated PSCCH resources and SL PRS resources based on the association relationship between the control channel resources and the SL PRS resources in the resource pool, and when indicating the SL PRS resources to other terminals, use the PSCCH resources to send SCI to other terminals.

[0151] Of course, the method provided in this application is not limited to the above-mentioned scenarios, and can be applied to other scenarios that require determination of target control channel resources and / or target SL PRS resources, which will not be described in detail later. It can be used for a variety of SL positioning technologies.

[0152] In some embodiments, the association relationship between the control channel resources in the resource pool and the SL PRS resources may be predefined, indicated by the network side, preconfigured, or determined by other means, and this application does not limit this.

[0153] The resource determination method provided in the embodiment of the present application enables the terminal to determine the target control channel resources and / or the target SL PRS resources through the association relationship between the control channel resources and the SL PRS resources, thereby effectively avoiding collision and interference between the SLPRS resources of different terminals.

[0154] In some embodiments, the association relationship between the control channel resources in the resource pool and the direct link positioning reference signal SL PRS resources includes:

[0155] A one-to-one correspondence between the control channel resources and the SL PRS resources in the resource pool; or,

[0156] A one-to-one correspondence between the control channel resources in the resource pool and the SL PRS resource set.

[0157] For example, the one-to-one correspondence between the control channel resources and the SL PRS resources in the resource pool can be a one-to-one correspondence between the control channel resources with the same number in the resource pool and the SL PRS resources, such as control channel resource i corresponds to SL PRS resource i, where i is the resource number; or it can be other one-to-one correspondences, which are not specifically limited in the present application, such as a one-to-one correspondence between frequency domain positions and numbers.

[0158] For example, the one-to-one correspondence between the control channel resources in the resource pool and the SL PRS resource set can be a one-to-one correspondence between the control channel resources with the same number in the resource pool and the SL PRS resource set, such as control channel resource j corresponds to SL PRS resource set j, where j is the number of the resource or resource set; or it can be other one-to-one correspondence, which is not specifically limited in the present application, for example, it can also be a one-to-one correspondence between the frequency domain position and the number.

[0159] In some embodiments, the SL PRS resource is associated with the frequency domain position of the control channel resource; or, the SL PRS resource set is associated with the frequency domain position of the control channel resource.

[0160] For example, the SL PRS resource may be associated with the start / end / center position of the control channel resource in the frequency domain, or the SL PRS resource set may be associated with the start / end / center position of the control channel resource in the frequency domain.

[0161] In an embodiment of the present application, the frequency domain position of the control channel resources in the resource pool may be determined by one or more of a predefined rule, a system preconfiguration, or a signaling indication.

[0162] In some embodiments, the frequency domain position of the control channel resources in the resource pool satisfies at least one of the following:

[0163] (1) The frequency domain positions of the control channel resources in the resource pool are evenly distributed within the bandwidth of the resource pool.

[0164] For example, the start / end / center positions of the control channel resources in the frequency domain may be evenly distributed within the bandwidth of the resource pool.

[0165] (2) The frequency domain position of the control channel resources in the resource pool is located at the boundary of the frequency domain unit.

[0166] The frequency domain unit may include a subchannel, a physical resource block (PRB), and other units divided in the frequency domain, and is not specifically limited. This concept remains consistent throughout the text and will not be repeated later.

[0167] In the present application, the boundary of a frequency domain unit refers to the starting position or ending position of the frequency domain unit in the frequency domain. The starting position of the frequency domain unit in the frequency domain (i.e., the frequency domain starting position of the frequency domain unit) can be called the starting boundary of the frequency domain unit, and the ending position of the frequency domain unit in the frequency domain (i.e., the frequency domain ending position of the frequency domain unit) can be called the ending boundary of the frequency domain unit.

[0168] The frequency domain position of the control channel resource is located at the boundary of the frequency domain unit, which can be understood as the specific frequency domain position of the control channel resource (such as the frequency domain starting position, the frequency domain ending position, the frequency domain center position, etc.) is aligned with the boundary of the frequency domain unit (the starting boundary or the ending boundary).

[0169] For example, the frequency domain starting position of the control channel resource may be located at the starting boundary of the subchannel, or the frequency domain starting position of the control channel resource may be located at the starting boundary of the PRB, or the frequency domain starting position of the control channel resource may be located at the ending boundary of the subchannel, and so on.

[0170] In some embodiments, the number of control channel resources in the resource pool is determined based on the number of SLPRS resources or SL PRS resource sets in the resource pool; or,

[0171] The number of SL PRS resources or SL PRS resource sets in the resource pool is determined based on the number of control channel resources in the resource pool.

[0172] For example, for the case where control channel resources correspond one-to-one with SL PRS resources, the number of control channel resources is equal to the number of SL PRS resources; for the case where control channel resources correspond one-to-one with SL PRS resource sets, the number of control channel resources is equal to the number of SL PRS resource sets.

[0173] In some embodiments, the frequency domain position of the control channel resources in the resource pool is determined based on the number of resources in the resource pool, the bandwidth of the resource pool, and the frequency domain starting position of the resource pool;

[0174] The number of resources in the resource pool includes the number of SL PRS resources in the resource pool, the number of SL PRS resource sets in the resource pool, or the number of control channel resources in the resource pool.

[0175] Specifically, when determining the frequency domain position of the control channel resource, it can be determined based on information such as the number of resources in the resource pool, the bandwidth of the resource pool, and the frequency domain starting position of the resource pool. The number of resources in the resource pool can be the number of SL PRS resources in the resource pool, the number of SL PRS resource sets in the resource pool, or the number of control channel resources in the resource pool, which is not limited here.

[0176] For example, when the frequency domain positions of the control channel resources in the resource pool are evenly distributed within the bandwidth of the resource pool, the frequency domain position of each control channel resource can be determined based on the bandwidth of the resource pool, the frequency domain starting position of the resource pool, and the number of control channel resources in the resource pool.

[0177] In some embodiments, the frequency domain position of the control channel resource in the resource pool is determined based on a first formula, wherein the first formula comprises:

[0178]

[0179] In the formula, F(i) represents the frequency domain starting position of the control channel resource i, F0 represents the frequency domain starting position of the resource pool, BW represents the bandwidth of the resource pool, and N represents the number of resources in the resource pool.

[0180] In some embodiments, the method further comprises:

[0181] After determining the frequency domain starting position of the control channel resources in the resource pool based on the first formula, the frequency domain starting position of the control channel resources in the resource pool is adjusted to the boundary of the frequency domain unit.

[0182] Specifically, after the frequency domain starting position of the control channel resources is evenly distributed within the bandwidth of the resource pool, the frequency domain starting position of the control channel resources can be further adjusted so that the frequency domain starting position of the control channel resources is located at the boundary of the frequency domain unit (such as the boundary of the subchannel or the boundary of the PRB).

[0183] In some embodiments, adjusting the frequency domain starting position of the control channel resources in the resource pool to the boundary of the frequency domain unit includes:

[0184] adjusting the frequency domain starting position of the first control channel resource in the resource pool to the frequency domain unit boundary closest to the frequency domain position of the first control channel resource; or,

[0185] Determine a first frequency domain unit where the frequency domain position of the first control channel resource in the resource pool is located, and adjust the frequency domain starting position of the first control channel resource to the boundary of the first frequency domain unit.

[0186] Specifically, there may be one or more first control channel resources, and the first control channel resource may be any control channel resource in the resource pool. In some embodiments, it may be a control channel resource in the resource pool whose frequency domain starting position is not at the frequency domain unit boundary.

[0187] In some embodiments, for a certain first control channel resource, the frequency domain unit boundary closest to its frequency domain position (which may be the frequency domain start / end / center position) can be determined first, and then its frequency domain start position can be aligned with the nearest frequency domain unit boundary.

[0188] In some embodiments, for a certain first control channel resource, the frequency domain unit (e.g., subchannel or PRB) in which it is located, i.e., the first frequency domain unit, can be determined first, and then its frequency domain starting position is aligned with the boundary (which can be the starting boundary or the ending boundary) of the first frequency domain unit. The first frequency domain unit can be the frequency domain unit in which the frequency domain starting position of the first control channel resource is located, or can be the frequency domain unit in which the frequency domain center position of the first control channel resource is located, or can be the frequency domain unit in which all frequency domain positions of the first control channel resource are located, etc., which are not limited here.

[0189] In some embodiments, the frequency domain position of the control channel resources in the resource pool is determined based on received frequency domain position indication information.

[0190] Specifically, in the case where the signaling indicates the frequency domain position of the control channel resource, other communication devices (such as network devices, head terminals in the sidelink system, etc.) can send frequency domain position indication information to the terminal, and the frequency domain position indication information can be used to indicate the frequency domain position of the control channel resource in the resource pool. Therefore, after the terminal receives the frequency domain position indication information, it can determine the frequency domain position of the control channel resource in the resource pool according to the frequency domain position indication information.

[0191] In some embodiments, the frequency domain position indication information includes a bitmap, and the bitmap is used to indicate the frequency domain positions of the N control channel resources in the resource pool.

[0192] Specifically, the frequency domain position indication information may be in the form of a bit map, and the frequency domain positions of the N control channel resources in the resource pool may be indicated by multiple bits in the bit map.

[0193] For example, other communication devices can determine the number N of control channel resources in the resource pool, and then indicate the frequency domain positions of these N control channel resources to the terminal through a bit map; or, other communication devices can determine the number N of control channel resources in the resource pool based on the number of SL PRS resources in the resource pool, and then indicate the frequency domain positions of these N control channel resources to the terminal through a bit map.

[0194] In some embodiments, the length of the bit map is the number of frequency domain units of the resource pool, and each bit in the bit map is used to indicate whether the frequency domain unit corresponding to the bit contains control channel resources.

[0195] For example, assuming that the length of the bitmap is the number of subchannels in the resource pool, and the resource pool contains 4 subchannels, the length of the bitmap is 4. The subchannel with control channel resources is set to 1, otherwise it is set to 0, then the bit with a value of 1 in the bitmap indicates that the frequency domain unit corresponding to the bit contains control channel resources, and the bit with a value of 0 in the bitmap indicates that the frequency domain unit corresponding to the bit does not contain control channel resources.

[0196] In some embodiments, when the first bit in the bit map indicates that the second frequency domain unit corresponding to the first bit contains control channel resources, the first bit is also used to indicate that the frequency domain starting position of the control channel resources contained in the second frequency domain unit is located at the starting boundary of the second frequency domain unit.

[0197] For example, assuming that the resource pool contains 4 subchannels, the subchannel with control channel resources is set to 1, otherwise it is set to 0, and a bit map of "1011" is used to indicate that subchannel 0, subchannel 2 and subchannel 3 contain control channel resources. The terminal can determine that the 3 control channel resources in the resource pool are located in subchannel 0, subchannel 2 and subchannel 3 respectively according to the bit map, and further determine that the frequency domain starting position of each control channel resource is aligned with the starting boundary of the subchannel where it is located.

[0198] In some embodiments, the frequency domain position indication information includes frequency domain position information of N control channel resources in the resource pool.

[0199] Specifically, the frequency domain position indication information may indicate specific information of the frequency domain position of each control channel resource in the N control channel resources in the resource pool, such as a frequency domain starting position, a frequency domain ending position, a frequency domain width, and the like.

[0200] In some embodiments, the frequency domain location information of the control channel resource includes one or more of the following:

[0201] The starting subcarrier position information of the control channel resource;

[0202] The frequency domain unit information where the control channel resource is located.

[0203] For example, the starting subcarrier position of each of the N control channel resources may be indicated separately, such as indicating that the starting subcarrier position of control channel resource 0 is F0, the starting subcarrier position of control channel resource 1 is F1, and so on; or the subchannel where each of the N control channel resources is located (or the starting subchannel of the control channel resources) may be indicated separately, or the PRB where each of the N control channel resources is located (or the starting PRB of the control channel resources) may be indicated separately, and so on.

[0204] In some embodiments, when the frequency domain unit where the control channel resource is located is indicated, the terminal may align the frequency domain starting position of each control channel resource with the starting boundary of the frequency domain unit.

[0205] In some embodiments, when the starting frequency domain unit of the control channel resource is indicated, the terminal may align the frequency domain starting position of each control channel resource with the starting boundary of the starting frequency domain unit.

[0206] The following describes the methods provided in the above embodiments of the present application by using examples of specific application scenarios.

[0207] Example 1: The frequency domain locations of the control channel resources are evenly distributed within the resource pool bandwidth.

[0208] Figure 2 One of the example diagrams of the dedicated resource pool structure provided in the embodiment of the present application, such as Figure 2 As shown, the terminal is pre-configured with a dedicated resource pool for SL positioning. Figure 2 The structure of PSCCH resources and SL PRS resources in a time slot is given, where SL PRS resources occupy the entire resource pool bandwidth. It includes N PSCCH resources and N SL PRS resources, where N = 3. AGC stands for Automatic Gain Control, and GP stands for Guard Period. The bandwidth of this dedicated resource pool is M = 4 subchannels, namely subchannel 0, subchannel 1, subchannel 2, and subchannel 3 in the figure.

[0209] The system predefines that within a time slot, PSCCH resources and SL PRS resources satisfy a one-to-one correspondence. One way is that PSCCH resources with the same number correspond one-to-one to SL PRS resources. That is, PSCCH resource i is associated with SL PRS resource i, i = 0, 1, ..., N-1. According to the rules predefined by the system, these N PSCCH resources are evenly distributed within the resource pool bandwidth, that is, the frequency domain starting position of PSCCH resource i is:

[0210] F0+i*BW / N

[0211] Among them, BW is the bandwidth of this dedicated resource pool, N is the number of SL-PRS resources included in this time slot, and F0 is the frequency domain starting position of this dedicated resource pool.

[0212] The terminal determines the number N of SL PRS resources in a time slot according to the configuration information of the dedicated resource pool. According to the predefined rules, the frequency domain positions of the N PSCCH resources are determined. The terminal obtains the SCI by blind detection on the PSCCH resource. Assuming that the terminal detects the SCI in PSCCH resource 1, it is determined that the associated resource is SL PRS resource 1, and this SCI is used for scheduling SL PRS resource 1.

[0213] Example 2: The frequency domain location of the control channel resource is located at the boundary of the frequency domain unit.

[0214] Figure 3 The second example diagram of the dedicated resource pool structure provided in the embodiment of the present application is as follows: Figure 3 As shown, the terminal is pre-configured with a dedicated resource pool for SL positioning. Figure 3 The structure of PSCCH resources and SL PRS resources in a time slot is given. It includes N PSCCH resources and N SL PRS resources, where N = 3. AGC stands for automatic gain control, and GP stands for guard interval. The bandwidth of this dedicated resource pool is M = 4 subchannels, namely subchannel 0, subchannel 1, subchannel 2, and subchannel 3 in the figure.

[0215] The system predefines that within a time slot, PSCCH resources and SL PRS resources satisfy a one-to-one correspondence. That is, PSCCH resource i is associated with SL PRS resource i, i = 0, 1, ..., N-1. According to the rules predefined by the system, the following two steps are used to determine the distribution of these N PSCCH resources within the resource pool bandwidth:

[0216] Step 1: The unadjusted frequency domain starting position of PSCCH resource i is:

[0217] F0+i*BW / N

[0218] Among them, BW is the bandwidth of this dedicated resource pool, N is the number of SL-PRS resources included in this time slot, and F0 is the frequency domain starting position of this dedicated resource pool.

[0219] Step 2: Adjust the unadjusted frequency domain starting position of PSCCH resource i in step 1 to the subchannel boundary. One implementation method is that the system agrees to adjust to the nearest subchannel boundary, which can be the boundary position of any two adjacent subchannels in the frequency domain, or the starting subchannel within the resource pool bandwidth (such as Figure 3 The starting boundary of subchannel 0 in . For example, Figure 3 There is a boundary between subchannel 0 and subchannel 1 in the frequency domain, which is the end boundary of subchannel 0 and the start boundary of subchannel 1. Figure 3In the embodiment, PSCCH resource 1 is adjusted to the starting boundary of subchannel 2, and PSCCH resource 2 is adjusted to the starting boundary of subchannel 3. Another implementation method is to determine according to the calculation rules agreed upon by the system. For example, according to the result in step 1, the subchannel in which it is located is determined, and the PSCCH resource is moved to the boundary of this subchannel (which can be the starting boundary or the ending boundary of the subchannel).

[0220] The terminal determines the number N of SL PRS resources in a time slot according to the configuration information of the dedicated resource pool. According to the predefined rules, the frequency domain positions of the N PSCCH resources are determined. The terminal obtains the SCI by blind detection on the PSCCH resource. Assuming that the terminal detects the SCI in PSCCH resource 1, it is determined that the associated resource is SL PRS resource 1, and this SCI is used for scheduling SL PRS resource 1.

[0221] Example 3: The bitmap indicates the frequency domain location of the control channel resources.

[0222] Figure 4 The third example diagram of the dedicated resource pool structure provided in the embodiment of the present application is as follows: Figure 4 As shown, the terminal is pre-configured with a dedicated resource pool for SL positioning. Figure 4 The structure of PSCCH resources and SL PRS resources in a time slot is given. It includes N PSCCH resources and N SL PRS resources, where N = 3. AGC stands for automatic gain control, and GP stands for guard interval. The bandwidth of this dedicated resource pool is M = 4 subchannels, namely subchannel 0, subchannel 1, subchannel 2, and subchannel 3 in the figure.

[0223] The system predefines that within a time slot, PSCCH resources and SL PRS resources satisfy a one-to-one correspondence. That is, PSCCH resource i is associated with SL PRS resource i, i = 0, 1, ..., N-1. At the same time, a bitmap is used to indicate the frequency domain position of the PSCCH resource of this dedicated resource pool. The length of the bitmap is the number of subchannels in this dedicated resource pool. For example Figure 4 If the dedicated resource pool in contains 4 subchannels, the length of the bitmap is 4. The subchannel with PSCCH resources is set to 1, otherwise it is set to 0. For example, using the bitmap indication of "1101", it means that PSCCH resources exist in subchannel 0, subchannel 1, and subchannel 3. The starting frequency domain position of each PSCCH resource is aligned with the starting boundary of the subchannel.

[0224] Another implementation is that the length of the bitmap is the number of PRBs in the dedicated resource pool. The bitmap indicates the PRB where the starting frequency domain position of each PSCCH resource is located, and the starting frequency domain position is aligned with the starting boundary of the PRB.

[0225] The terminal determines the number N of SL PRS resources in a time slot based on the configuration information of the dedicated resource pool. At the same time, the frequency domain positions of the N PSCCH resources are determined based on the bitmap information. The terminal obtains the SCI through blind detection on the PSCCH resource. Assuming that the terminal detects the SCI in PSCCH resource 1, it is determined that the associated resource is SL PRS resource 1, and this SCI is used for scheduling SL PRS resource 1.

[0226] Example 4: The frequency domain position indication information indicates the frequency domain position of the control channel resource.

[0227] Figure 5 The fourth example diagram of the dedicated resource pool structure provided in the embodiment of the present application is as follows: Figure 5 As shown, the terminal is pre-configured with a dedicated resource pool for SL positioning. Figure 5 The structure of PSCCH resources and SL PRS resources in a time slot is given. It includes N PSCCH resources and N SL PRS resources, where N = 3. AGC stands for automatic gain control, and GP stands for guard interval. The bandwidth of this dedicated resource pool is M = 4 subchannels, namely subchannel 0, subchannel 1, subchannel 2, and subchannel 3 in the figure.

[0228] The system predefines that within a time slot, PSCCH resources and SL PRS resources satisfy a one-to-one correspondence. That is, PSCCH resource i is associated with SL PRS resource i, i=0, 1, ..., N-1. At the same time, signaling is used to indicate the frequency domain position of the PSCCH resources of this dedicated resource pool. For example, the starting subcarrier position of each of the N PSCCH resources is indicated separately, such as indicating that the starting subcarrier position of PSCCH resource 0 is F0, the starting subcarrier position of PSCCH resource 1 is F1, and so on; or the subchannel position of each of the N PSCCH resources is indicated separately, or the starting PRB position of each of the N PSCCH resources is indicated separately.

[0229] The terminal determines the number N of SL PRS resources in a time slot according to the configuration information of the dedicated resource pool. At the same time, according to the configuration of the signaling, the frequency domain positions of the N PSCCH resources are determined. The terminal obtains the SCI through blind detection on the PSCCH resource. Assuming that the terminal detects the SCI in PSCCH resource 1, it is determined that the associated resource is SL PRS resource 1, and this SCI is used for scheduling SL PRS resource 1.

[0230] Figure 6 A flow chart of the information indication method provided in the embodiment of the present application is as follows: Figure 6 As shown, the method comprises the following steps:

[0231] Step 600: Send frequency domain position indication information to the terminal, where the frequency domain position indication information is used to indicate the frequency domain position of the control channel resource in the resource pool.

[0232] Specifically, the execution subject of the information indication method can be any communication device such as a network device, a head terminal in a sidelink system, etc., and is not limited here.

[0233] The communication device may send frequency domain position indication information to the terminal, and the frequency domain position indication information may be used to indicate the frequency domain position of the control channel resource in the resource pool. Thus, after receiving the frequency domain position indication information, the terminal may determine the frequency domain position of the control channel resource in the resource pool according to the frequency domain position indication information.

[0234] The information indication method provided in the embodiment of the present application can assist the terminal in determining the target control channel resources and / or target SLPRS resources by sending frequency domain position indication information to the terminal to indicate the frequency domain position of the control channel resources in the resource pool, thereby avoiding collision and interference between SL PRS resources of different terminals.

[0235] In some embodiments, the frequency domain position indication information includes a bit map, and the bit map is used to indicate the frequency domain positions of the N control channel resources in the resource pool.

[0236] Specifically, the frequency domain position indication information may be in the form of a bit map, and the frequency domain positions of the N control channel resources in the resource pool may be indicated by multiple bits in the bit map.

[0237] For example, the communication device can determine the number N of control channel resources in the resource pool, and then indicate the frequency domain positions of these N control channel resources to the terminal through a bit map; or, the communication device can determine the number N of control channel resources in the resource pool based on the number of SL PRS resources in the resource pool, and then indicate the frequency domain positions of these N control channel resources to the terminal through a bit map.

[0238] In some embodiments, the length of the bit map is the number of frequency domain units of the resource pool, and each bit in the bit map is used to indicate whether the frequency domain unit corresponding to the bit contains control channel resources.

[0239] For example, assuming that the length of the bitmap is the number of subchannels in the resource pool, and the resource pool contains 4 subchannels, the length of the bitmap is 4. The subchannel with control channel resources is set to 1, otherwise it is set to 0, then the bit with a value of 1 in the bitmap indicates that the frequency domain unit corresponding to the bit contains control channel resources, and the bit with a value of 0 in the bitmap indicates that the frequency domain unit corresponding to the bit does not contain control channel resources.

[0240] In some embodiments, when the first bit in the bit map indicates that the second frequency domain unit corresponding to the first bit contains control channel resources, the first bit is also used to indicate that the frequency domain starting position of the control channel resources contained in the second frequency domain unit is located at the starting boundary of the second frequency domain unit.

[0241] For example, assuming that the resource pool contains 4 subchannels, the subchannel with control channel resources is set to 1, otherwise it is set to 0, and a bit map of "1011" is used to indicate that subchannel 0, subchannel 2 and subchannel 3 contain control channel resources. The terminal can determine that the 3 control channel resources in the resource pool are located in subchannel 0, subchannel 2 and subchannel 3 respectively according to the bit map, and further determine that the frequency domain starting position of each control channel resource is aligned with the starting boundary of the subchannel where it is located.

[0242] In some embodiments, the frequency domain position indication information includes frequency domain position information of N control channel resources in the resource pool.

[0243] Specifically, the frequency domain position indication information may indicate specific information of the frequency domain position of each control channel resource in the N control channel resources in the resource pool, such as a frequency domain starting position, a frequency domain ending position, a frequency domain width, and the like.

[0244] In some embodiments, the frequency domain location information of the control channel resource includes one or more of the following:

[0245] The starting subcarrier position information of the control channel resource;

[0246] The frequency domain unit information where the control channel resource is located.

[0247] For example, the starting subcarrier position of each of the N control channel resources may be indicated separately, such as indicating that the starting subcarrier position of control channel resource 0 is F0, the starting subcarrier position of control channel resource 1 is F1, and so on; or the subchannel where each of the N control channel resources is located (or the starting subchannel of the control channel resources) may be indicated separately, or the PRB where each of the N control channel resources is located (or the starting PRB of the control channel resources) may be indicated separately, and so on.

[0248] In some embodiments, when the frequency domain unit where the control channel resource is located is indicated, the terminal may align the frequency domain starting position of each control channel resource with the starting boundary of the frequency domain unit.

[0249] In some embodiments, when the starting frequency domain unit of the control channel resource is indicated, the terminal may align the frequency domain starting position of each control channel resource with the starting boundary of the starting frequency domain unit.

[0250] The methods provided in the embodiments of the present application are based on the same application concept, so the implementation of each method can refer to each other, and the repeated parts will not be repeated.

[0251] The methods and devices provided in the various embodiments of the present application are based on the same application concept.
