[0136] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

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

[0138] In the embodiments of the present disclosure, the terms "first," "second," and the like are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present disclosure can be implemented in an order other than that illustrated or described herein. Furthermore, the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more.

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

[0140] FIG1 is a flow chart of a resource determination method provided by an embodiment of the present disclosure. The method can be applied to a terminal. As shown in FIG1 , the method includes 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 disclosure 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 SL PRS 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 certain) 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 resource.

[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 the resource allocation indication received by the terminal indicates a certain SL PRS resource, 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 can determine the 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 use the PSCCH resources to send SCI to other terminals when indicating the SL PRS resources to other terminals.

[0151] Of course, the method provided by the present disclosure is not limited to the above-mentioned scenarios, and can be applied to other scenarios where target control channel resources and / or target SL PRS resources need to be determined, which will not be described in detail later. It can be used for various 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 disclosure does not limit this.

[0153] The resource determination method provided in the embodiment of the present disclosure can enable the terminal to determine the target control channel resources and / or 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 SL PRS resources of different terminals.

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

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

[0156] There is a one-to-one correspondence between control channel resources and SL PRS resource sets in the resource pool.

[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 and the SL PRS resources with the same number in the resource pool, 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 this disclosure, 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 the control channel resource j corresponds to the SL PRS resource set j, where j is the number of the resource or resource set; or it can be other one-to-one correspondences, which are not specifically limited in this disclosure, such as 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 location of the control channel resource; or, the SL PRS resource set is associated with the frequency domain location of the control channel resource.

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

[0161] In the embodiment of the present disclosure, 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 location of the control channel resources in the resource pool satisfies one or more 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 frequency domain start / end / center positions of the control channel resources may be evenly distributed within the bandwidth of the resource pool.

[0165] (2) The frequency domain location 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 disclosure, the boundary of the 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 SL PRS resources in the resource pool or the number of SL PRS resource sets in the resource pool; or,

[0171] The number of SL PRS resources in the resource pool or the number of 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, in the case where 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, the first formula comprising:

[0178] Where 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.

[0179] In some embodiments, the method further comprises:

[0180] 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.

[0181] 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).

[0182] 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:

[0183] 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,

[0184] Determine a first frequency domain unit in which a frequency domain position of a first control channel resource in the resource pool is located, and adjust a frequency domain starting position of the first control channel resource to a boundary of the first frequency domain unit.

[0185] Specifically, there may be one or more first control channel resources. 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.

[0186] 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.

[0187] In some embodiments, for a certain first control channel resource, the frequency domain unit (e.g., a subchannel or PRB) in which it is located can be first determined, i.e., the first frequency domain unit, 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 where the frequency domain starting position of the first control channel resource is located, or can be the frequency domain unit where the frequency domain center position of the first control channel resource is located, or can be the frequency domain unit where all frequency domain positions of the first control channel resource are located, etc., and is not limited here.

[0188] In some embodiments, the frequency domain position of the control channel resource in the resource pool is determined based on the received frequency domain position indication information.

[0189] Specifically, when signaling indicates the frequency domain location of a control channel resource, other communications devices (e.g., network devices, head terminals in a sidelink system, etc.) can send frequency domain location indication information to the terminal. This frequency domain location indication information can be used to indicate the frequency domain location of the control channel resource in the resource pool. Thus, after receiving this frequency domain location indication information, the terminal can determine the frequency domain location of the control channel resource in the resource pool based on this frequency domain location indication information.

[0190] In some embodiments, the frequency domain position indication information includes a bitmap, where the bitmap is used to indicate the frequency domain positions of N control channel resources in the resource pool, where N is the number of control channel resources in the resource pool.

[0191] Specifically, the frequency domain position indication information may be in the form of a bitmap, and the frequency domain positions of the N control channel resources in the resource pool may be indicated by multiple bits in the bitmap.

[0192] 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.

[0193] In some embodiments, the length of the bitmap is the number of frequency domain units in the resource pool, and each bit in the bitmap is used to indicate whether the frequency domain unit corresponding to the bit contains control channel resources or does not contain control channel resources.

[0194] 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 a control channel resource is set to 1, otherwise it is set to 0. Then, a bit with a value of 1 in the bitmap indicates that the frequency domain unit corresponding to the bit contains a control channel resource, and a bit with a value of 0 in the bitmap indicates that the frequency domain unit corresponding to the bit does not contain a control channel resource.

[0195] 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.

[0196] For example, assuming that the resource pool contains 4 subchannels, the subchannel where the control channel resource exists is set to 1, otherwise it is set to 0, and the 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.

[0197] In some embodiments, the frequency domain position indication information includes frequency domain position information of N control channel resources in the resource pool, where N is the number of control channel resources in the resource pool.

[0198] 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 the frequency domain starting position, the frequency domain ending position, the frequency domain width, and the like.

[0199] In some embodiments, the frequency domain location information of the control channel resources includes one or more of the following:

[0200] The starting subcarrier position information of the control channel resource;

[0201] Frequency domain unit information where the control channel resources are located.

[0202] For example, the starting subcarrier position of each of the N control channel resources can 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 resource) can be indicated separately, or the PRB where each of the N control channel resources is located (or the starting PRB of the control channel resource) can be indicated separately, and so on.

[0203] 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.

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

[0205] The following describes the methods provided in the above embodiments of the present disclosure through examples of specific application scenarios.

[0206] Example 1: The frequency domain locations of the control channel resources are evenly distributed within the resource pool bandwidth.

[0207] Figure 2 is one of the example diagrams of the dedicated resource pool structure provided by the embodiment of the present disclosure. As shown in Figure 2, the terminal is pre-configured with a dedicated resource pool for SL positioning. Figure 2 shows the structure of PSCCH resources and SL PRS resources in a time slot, where the 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.

[0208] The system predefines that within a time slot, PSCCH resources and SL PRS resources satisfy a one-to-one correspondence. One way is to have the same numbered PSCCH resources correspond one-to-one with SL PRS resources. That is, PSCCH resource i is associated with SL PRS resource i, i = 0, 1, ..., N-1. According to the system predefined rules, these N PSCCH resources are evenly distributed within the resource pool bandwidth, that is, the frequency domain starting position of PSCCH resource i is:

[0209] F0+i*BW / N

[0210] Wherein, BW is the bandwidth of this dedicated resource pool, N is the number of SL-PRS resources contained in this time slot, and F0 is the frequency domain starting position of this dedicated resource pool.

[0211] Based on the configuration information of the dedicated resource pool, the terminal determines the number N of SL PRS resources within a time slot. Based on predefined rules, the terminal determines the frequency domain locations of the N PSCCH resources. The terminal obtains the SCI through blind detection on the PSCCH resources. Assuming that the terminal detects the SCI in PSCCH resource 1, it determines that the associated resource is SL PRS resource 1, and this SCI is used for scheduling SL PRS resource 1.

[0212] Example 2: The frequency domain location of the control channel resource is located at the boundary of the frequency domain unit.

[0213] Figure 3 is a second example diagram of a dedicated resource pool structure provided by an embodiment of the present disclosure. As shown in Figure 3, a terminal is preconfigured with a dedicated resource pool for SL positioning. Figure 3 shows the structure of PSCCH resources and SL PRS resources within a time slot. This 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.

[0214] The system predefines a one-to-one correspondence between PSCCH resources and SL PRS resources within a time slot. That is, PSCCH resource i is associated with SL PRS resource i, where i = 0, 1, ..., N-1. Based on the system's predefined rules, the following two steps are used to determine the distribution of these N PSCCH resources within the resource pool bandwidth:

[0215] Step 1: The unadjusted frequency domain starting position of PSCCH resource i is:

[0216] F0+i*BW / N

[0217] Wherein, BW is the bandwidth of this dedicated resource pool, N is the number of SL-PRS resources contained in this time slot, and F0 is the frequency domain starting position of this dedicated resource pool.

[0218] 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 intersection position of any two adjacent subchannels in the frequency domain, or the starting boundary of the starting subchannel within the resource pool bandwidth (such as subchannel 0 in Figure 3). For example, in Figure 3, subchannel 0 and subchannel 1 have an intersection position in the frequency domain, and the intersection position is the end boundary of subchannel 0 and also the starting boundary of subchannel 1. As shown in Figure 3, 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 it according to the calculation rules agreed upon by the system. For example, according to the result in step 1, determine the subchannel it is in, and move the PSCCH resource to the boundary of this subchannel (which can be the starting boundary or the ending boundary of the subchannel).

[0219] Based on the configuration information of the dedicated resource pool, the terminal determines the number N of SL PRS resources within a time slot. Based on predefined rules, the terminal determines the frequency domain locations of the N PSCCH resources. The terminal obtains the SCI through blind detection on the PSCCH resources. Assuming that the terminal detects the SCI in PSCCH resource 1, it determines that the associated resource is SL PRS resource 1, and this SCI is used for scheduling SL PRS resource 1.

[0220] Example 3: The bitmap indicates the frequency domain location of the control channel resources.

[0221] Figure 4 is a third example diagram of a dedicated resource pool structure provided by an embodiment of the present disclosure. As shown in Figure 4, a terminal is pre-configured with a dedicated resource pool for SL positioning. Figure 4 shows the structure of PSCCH resources and SL PRS resources within a time slot. This 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.

[0222] 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, the dedicated resource pool in Figure 4 contains 4 subchannels, so the length of the bitmap is 4. The subchannel where there is a PSCCH resource is set to 1, otherwise it is set to 0. For example, using the bitmap indication of "1101" means that there are PSCCH resources 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.

[0223] In another embodiment, 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.

[0224] Based on the configuration information of the dedicated resource pool, the terminal determines the number N of SL PRS resources within a time slot. Simultaneously, based on the bitmap information, it determines the frequency domain locations of the N PSCCH resources. The terminal obtains the SCI through blind detection on the PSCCH resources. Assuming that the terminal detects the SCI in PSCCH resource 1, it determines that the associated resource is SL PRS resource 1, and this SCI is used for scheduling SL PRS resource 1.

[0225] Example 4: The frequency domain position indication information indicates the frequency domain position of the control channel resource.

[0226] Figure 5 is a fourth example diagram of a dedicated resource pool structure provided by an embodiment of the present disclosure. As shown in Figure 5, a terminal is pre-configured with a dedicated resource pool for SL positioning. Figure 5 shows the structure of PSCCH resources and SL PRS resources within a time slot. This 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.

[0227] 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.

[0228] Based on the configuration information of the dedicated resource pool, the terminal determines the number N of SL PRS resources within a time slot. Simultaneously, based on the signaling configuration, it determines the frequency domain locations of the N PSCCH resources. The terminal obtains the SCI through blind detection on the PSCCH resources. Assuming that the terminal detects the SCI in PSCCH resource 1, it determines that the associated resource is SL PRS resource 1, and this SCI is used for scheduling SL PRS resource 1.

[0229] FIG6 is a flow chart of an information indication method provided by an embodiment of the present disclosure. As shown in FIG6 , the method includes the following steps:

[0230] 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.

[0231] 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.

[0232] The communication device may send frequency domain position indication information to the terminal, where 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.

[0233] The information indication method provided by the embodiment of the present disclosure can assist the terminal in determining the target control channel resources and / or target SL PRS 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.

[0234] 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 N control channel resources in the resource pool, where N is the number of control channel resources in the resource pool.

[0235] Specifically, the frequency domain position indication information may be in the form of a bitmap, and the frequency domain positions of the N control channel resources in the resource pool may be indicated by multiple bits in the bitmap.

[0236] 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.

[0237] In some embodiments, the length of the bitmap is the number of frequency domain units in the resource pool, and each bit in the bitmap is used to indicate whether the frequency domain unit corresponding to the bit contains control channel resources or does not contain control channel resources.

[0238] 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 a control channel resource is set to 1, otherwise it is set to 0. Then, a bit with a value of 1 in the bitmap indicates that the frequency domain unit corresponding to the bit contains a control channel resource, and a bit with a value of 0 in the bitmap indicates that the frequency domain unit corresponding to the bit does not contain a control channel resource.

[0239] 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.

[0240] For example, assuming that the resource pool contains 4 subchannels, the subchannel where the control channel resource exists is set to 1, otherwise it is set to 0, and the 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.

[0241] In some embodiments, the frequency domain position indication information includes frequency domain position information of N control channel resources in the resource pool, where N is the number of control channel resources in the resource pool.

[0242] 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 the frequency domain starting position, the frequency domain ending position, the frequency domain width, and the like.

[0243] In some embodiments, the frequency domain location information of the control channel resources includes one or more of the following:

[0244] The starting subcarrier position information of the control channel resource;

[0245] Frequency domain unit information where the control channel resources are located.

[0246] For example, the starting subcarrier position of each of the N control channel resources can 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 resource) can be indicated separately, or the PRB where each of the N control channel resources is located (or the starting PRB of the control channel resource) can be indicated separately, and so on.

[0247] 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.

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

[0249] The methods provided in the various embodiments of the present disclosure 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.

[0250] The methods and devices provided in the various embodiments of the present disclosure are based on the same application concept.
