Description

Technical Field

[0001] This invention relates to the field of wireless communication technology, and in particular to a reference signal transmission method, an electronic device, and a storage medium. Background Technology

[0002] With the development of wireless communication technology and the increasing communication demands of users, fifth-generation (5G) communication technology has become the trend of network development to meet the requirements of low latency, high reliability, and high speed. In sidelink (SL) communication systems, when user equipment (UE) needs to transmit services, the service data between UEs does not pass through the network side, that is, it is not forwarded through the cellular link between the UE and the base station, but is instead... Figure 1 The illustrated link is directly transmitted from the data source UE to the target UE via SL. This technology can alleviate the burden on cellular networks, reduce battery power consumption of user equipment, and improve the robustness of network infrastructure. It can well meet the requirements of high data rate services and proximity services, and also supports direct communication in scenarios without network coverage, thus meeting special communication needs such as public safety.

[0003] Currently, SL communication is mainly on the FR1 band. In 3GPP Release 18, it was agreed that SL could communicate on FR2. When SL communicates on the FR2 band, it is necessary to consider using beams to enhance communication performance. However, the configuration method for Reference Signal (RS) resources for beam management on SL is not clear at present. The SL communication scenario is different from NR Uu, and it is necessary to solve the interference problem between channels or signals between different UEs. Therefore, the CSI-RS resource configuration scheme for beam management defined by NR Uu cannot be reused for sidelink communication. Therefore, under the existing rules, UEs cannot transmit and receive channel state information reference signals on SL. Summary of the Invention

[0041] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are intended to limit the scope of the invention.

[0042] In the following description, the use of suffixes such as “module,” “part,” or “unit” to denote elements is merely for the convenience of the description of the invention and has no particular meaning in itself. Therefore, “module,” “part,” or “unit” may be used interchangeably.

[0043] In 5G communication systems, the smallest resource unit in the time domain is a symbol. A time slot is further composed of 12 consecutive symbols with an Extended Cycle Prefix (ECP) or 14 consecutive symbols with a Normal Cycle Prefix (NCP), or a mini-slot is composed of one or more consecutive symbols (less than or equal to seven symbols). The smallest resource unit in the frequency domain is a subcarrier. Subcarrier sizes have a finite number of selectable values ​​(15kHz, 30kHz, 60kHz, 120kHz, 240kHz). A frequency domain resource block (RB) is composed of 12 consecutive subcarriers, and the RB is the resource unit for frequency domain resource configuration. When implementing SL communication in a 5G communication system, the same time-domain and frequency-domain resource units are used as a foundation. Further, a set of time-domain and frequency-domain resource units constitutes an SL communication resource pool (sidelink resource pool). Within this resource pool, the UE performs SL communication based on configured or pre-configured resources. See also... Figure 2 The method for determining the SL communication resource pool consists of three steps:

[0044] First, based on the BandWidthPart (BWP) configuration on the SL carrier, determine all physical slot resources within the System Frame Number (SFN) period;

[0045] • Secondly, in all physical slots within the SFN period of the SL BWP on the SL carrier, after deducting unavailable slots such as the configured SL-SSB slot and DL slot, and reserved slots, the logical slots of the first step are formed.

[0046] Finally, based on the configured or pre-configured bitmap parameters, select the slots that are mapped to 1 in the logical slots from the previous step to form the logical slots in the SL resource pool.

[0047] In NR SL, a maximum of 8 transmit resource pools and 16 receive resource pools can typically be configured. Furthermore, the UE can transmit and receive data within the configured or pre-configured SL resource pools. The first available symbol in a slot on a resource pool is typically used as an AGC (Automatic Gain Control), while the last symbol is not transmitted and serves as a GAP (Gap). Currently, PSCCH, PSSCH, PSFCH, and DMRS signals are further configured in the SL resource pools for CSI-RS (Channel Signaling System) used for channel measurements.

[0048] Figure 3 This is a flowchart illustrating a reference signal transmission method provided in an embodiment of this application. This embodiment is applicable to reference signal transmission in sidelinks. The method can be executed by a reference signal transmission device, which can be implemented using software and / or hardware methods and is generally integrated into the user terminal. See [link to relevant documentation]. Figure 3 The method provided in this application specifically includes the following steps:

[0049] Step 110: Configure the side link data resource set.

[0050] In this embodiment of the application, the data resource set can be a resource pool used for data transmission in a side link, and the data resource set can be obtained through, for example... Figure 2 The configuration shown can include one or more data resources. Furthermore, the data resource set can also be configured with physical side link control channels such as PSCCH, PSSCH, PSFCH, and DMRS signals.

[0051] Step 120: Configure the reference signal resource set according to the data resource set.

[0052] The reference signal resource set can be a configured or pre-configured resource pool or logical resource set.

[0053] Specifically, the reference signal resource set can be configured based on the data resource set configured on the side link, so that the data resources in the data resource set can correspond to the reference signal resource set.

[0054] Step 130: Send a reference signal on the reference signal resource set corresponding to the data resource in the data resource set.

[0055] In this embodiment of the application, after the reference signal resource set is configured, the configured reference signal resource set can be used to transmit reference signals, wherein each reference signal resource in the reference signal resource set can be used for transmitting or receiving reference signals.

[0056] In this embodiment of the application, by configuring a side link data resource set and configuring a reference signal resource set based on the data resource set, and transmitting reference signals on the reference signal resource set corresponding to the data resources in the data resource set, the configuration of reference signal resources and the transmission of signals based on reference signal resources under side link communication can be realized, which can reduce interference between communication terminals in the side link and improve communication quality.

[0057] Furthermore, based on the above application embodiments, the data resource set includes at least one reference signal resource pool of the reference signal resource set.

[0058] The reference signal resource pool can be a resource pool consisting of at least one set of reference signal resources, and the reference signal resource pool can be used for the transmission of reference signals.

[0059] In the embodiments of this application, the reference signal resource pool can be configured based on the data resource set. For example, the reference signal resource pool can be configured based on the logical time slots of the data resource set; or, for example, the reference signal resource pool can be determined based on the bitmap of the physical time slots or logical time slots.

[0060] Furthermore, in one embodiment, the set of reference signal resources includes at least one reference signal resource, which is distributed within a time slot or on at least two time slots.

[0061] In the embodiments of this application, the reference signal resource set may include multiple reference signal resources, each of which may be located in the same time slot or in different time slots.

[0062] Furthermore, in one embodiment, different reference signal resources in the reference signal resource set are located in the same time slot or different time slots.

[0063] Specifically, the reference signal resources in the reference signal resource set can be located in the same time slot or in different time slots. For example, the last symbol of reference signal resource A in the reference signal resource set can be located in the same time slot as the first symbol of reference signal resource B, or the symbols included in reference signal resource C and the symbols included in reference signal resource D can be located in different time slots.

Each reference signal resource in the reference signal resource set may be configured on the logical time slots of the data resource set to form one or more reference signal resource sets. It is understood that the formed reference signal resource set may be a reference signal resource pool or a logical set of reference signal resources.

[0068] Step 230: Send a reference signal on the reference signal resource set corresponding to the data resource set in the data resource set.

Each reference signal resource can be determined based on either logical time slots or physical time slots. For example, a bitmap can be used to select physical time slots as reference signal resources.

[0074] Furthermore, based on the above-mentioned application embodiments, the reference signal resource set includes reference signal resources with the same resource density, number of ports, code division multiplexing type, and resource block distribution range.

[0075] Specifically, the resource density, number of ports, code division multiplexing type, and resource block distribution range of each reference signal resource in the configured reference signal resource set are the same.

[0078] Furthermore, based on the above-mentioned application embodiments, the reference signal resources are configured using two of the following parameters: start symbol, number of consecutive symbols, and end symbol.

[0079] Specifically, a reference signal resource may have at least two of the following parameters: start symbol, number of consecutive symbols, and end symbol. When configuring a reference signal resource, the start symbol and the number of consecutive symbols can be used to configure the reference signal resource, or the start symbol and the end symbol can be used to configure the reference signal resource, or the number of consecutive symbols and the end symbol can be used to configure the reference signal resource.

[0080] Furthermore, based on the above-mentioned application embodiments, the reference signal resource set includes resource units of the reference signal resources distributed in each resource block of the resource block set according to the resource unit pattern and density, wherein the resource block set includes the distribution range of the frequency domain resource blocks of the reference signal resources.

[0081] In the embodiments of this application, each reference signal resource can be distributed in each resource block according to the resource cell pattern and density within a certain resource block set. The resource block set can be the distribution range of frequency domain resource blocks of all reference signal resources.

[0082] Furthermore, the spatial transmission filters for the reference signal resources are the same.

[0083] Specifically, the spatial transmission filters used for each symbol in the reference signal resource are the same.

[0084] Furthermore, the reference signal resources include reference signal sequences of symbols, which are generated separately.

[0085] In the embodiments of this application, the symbol sequence of each reference signal resource can be generated separately, and the symbol sequences of different reference signal resources can be unrelated.

[0086] Furthermore, the reference signal sequence of other symbols on the reference signal resource, except for the designated symbol, is a repetition of the reference signal sequence on the designated symbol, wherein the designated symbol includes the first symbol on the reference signal resource and the last symbol on the reference signal resource.

[0087] Specifically, the reference signal sequences of multiple symbols in the reference signal resource can be the same. For example, they can be the reference signal sequences of other symbols in the reference signal resource, a repetition of the reference signal sequence of the first symbol, or a repetition of the reference signal sequence of the last symbol.

[0088] Furthermore, based on the above-described embodiments, the reference signal resource has a uniquely determined resource identifier within the reference signal resource set.

[0117] In this embodiment of the application, after determining the reference signal resource set corresponding to the data resource set, the reference signal transmitted on the corresponding reference signal resource set is received for each data resource.

[0118] In this embodiment of the application, by configuring a side link data resource set and configuring a reference signal resource set based on the data resource set, and receiving reference signals on the reference signal resource set corresponding to the data resources in the data resource set, the configuration of reference signal resources under side link communication and the reception of signals based on reference signal resources can be realized, which can reduce interference between communication terminals in the side link and improve communication quality.

[0132] Furthermore, the reference signal sequence of other symbols on the reference signal resource, except for the designated symbol, is a repetition of the reference signal sequence on the designated symbol, wherein the designated symbol includes the first symbol on the reference signal resource and the last symbol on the reference signal resource.

[0148] Furthermore, the data resource set corresponds to the reference signal resource pool.

[0149] Furthermore, different data resources within the data resource set correspond to different reference signal resource sets within the reference signal resource pool.

[0150] Furthermore, based on the above-described embodiments, the correspondence between data resources and the reference signal resource set is based on explicit or implicit indication.

[0151] Furthermore, based on the above-described embodiments, the indication includes at least one of the following: SCI instruction, MAC CE instruction.

[0152] Taking the configuration of CSI-RS resources in a Beam management scenario when the SL operates in the FR2 band as an example, it can be understood that in the embodiment, configuration and pre-configuration are used: configuration generally comes from the network or base station and is sent to the UE from the network or base station via signaling; pre-configuration is generally provided by other higher-layer entities, such as the UE's own higher layers, other network entities, etc. The distinction between configuration and pre-configuration will not be strictly defined thereafter, and the following description of configuration also includes the case of pre-configuration. Furthermore, "higher-layer entity" will be used to refer to the base station, network, or other higher-layer entities. The System Frame Number (SFN) or Direct Frame Number (DFN) is used to refer to the frame number on the sidelink. One SFN or DFN has a length of 10ms. One SFN or DFN has a period of 10240ms. Reference signal resources are not limited to CSI-RS resources and may also include Positioning Reference Signals (PRS).

[0153] In an exemplary implementation, the CSI-RS resources of each transmit resource pool are (pre) configured based on the logical time slots on the SL resource pool, and the granularity of the configured CSI-RS resources is: at least one single candidate beam transmission resource within at least one time slot, referred to as a single candidate beam set resource. The PSCCH / PSSCH resources in each SL resource pool can uniquely correspond to at least one single candidate beam set resource, and different PSCCH / PSSCH resources correspond to different single candidate beam set resources.

[0154] Specifically, the configuration process may include: after determining the transmit resource pool of SL within the BWP on the SL carrier, configuring at least one of the following parameters on the logical slot within the resource pool within one SFN period: CSI-RS transmission timing period P, CSI-RS frequency domain range (including at least one frequency domain RBset), number of single candidate beam set resources within period P, at least one single candidate beam transmission resource above the single candidate beam set resource, minimum time interval G associated with the slot where CSI-RS is located and PSSCH / PSSCH, and parameters related to the single candidate beam transmission resource. The parameters include at least one of the following: period P, slot offset within the single candidate beam set resource, reference signal frequency domain resource block range RBset, reference signal transmission parameters within the resource block. Further, the reference signal transmission parameters include the frequency domain resource unit position within the resource block, the time domain symbol position within the slot, the number of ports, density, code division multiplexing type, power, etc.

[0155] The parameters configured above determine M candidate beam transmission resources within a CSI-RS transmission cycle. Further, based on these M candidate beam transmission resources, N candidate beam set resources and L PSCCH / PSSCH transmission resources associated with the candidate beam set resources within the cycle are determined, where L = N_sub * P, and N_sub is the number of subchannels in the resource pool. Each PSCCH / PSSCH resource in the SL resource pool uniquely corresponds to at least one candidate beam set resource, and different PSCCH / PSSCH resources correspond to different candidate beam set resources. This correspondence can be predefined, configured, or pre-configured.

[0156] Specifically, the location of the single candidate beam set resource used by the UE is determined based on the explicit signaling and implicit correspondence.

[0157] For example, the transmitting UE can transmit signals on a single candidate beam set resource determined on the PSCCH / PSSCH in the transmitting resource pool, and the receiving UE can receive and measure signals on a single candidate beam set resource determined on the PSCCH / PSSCH in the receiving resource pool.

[0158] Furthermore, in the above embodiments, a single candidate beam resource can be a CSI-RS resource used for transmitting a single beam, referred to as a single candidate beam transmission resource. A single candidate beam transmission resource refers to a CSI-RS time-frequency resource configured or pre-configured in an SL slot for transmitting a single beam. At least one single candidate beam resource can exist in a slot. Based on the (pre)configuration, there can also be L (L>=1) SL slots for transmitting a larger number of single candidate beam resources. Multiple single candidate beam transmission resources constitute a single candidate beam set resource, which can be used for transmitting or receiving at least one beam in a beam management process.

[0159] Among them, a single candidate Beam set resource has at least one of the following characteristics:

[0160] 1. A single candidate beam set resource contains multiple single candidate beam transmission resources. These multiple single candidate beam transmission resources can be distributed within one slot or across different slots.

[0161] 2. The density, number of ports, code division multiplexing type, and resource block (RB) distribution range of single candidate beam transmission resources within a single candidate beam set resource are the same.

[0162] A single candidate Beam transport resource has at least one of the following characteristics:

[0163] 1. Temporal characteristics:

[0164] (1) The single candidate beam transmission resources within a slot are distributed across at least two consecutive symbols. The configuration includes: a starting symbol, a number of consecutive symbols, and a last symbol position of at least two. It can be understood that the last symbol of the last single beam transmission resource within a slot is located at startSLsymbols + lengthSLsymbols - m, where startSLsymbols represents the starting symbol position on the SL slot within the SL resource pool, with a value ranging from 0 to 13; lengthSLsymbols represents the number of consecutive SL symbols used for SL transmission on the SL slot within the SL resource pool, with a maximum value of 14; and m is the symbol-level offset of the last symbol of the single candidate beam transmission resource within the slot relative to the last symbol on the SL slot. Preferably, m = 2; optionally, m = 5 or m is another value.

[0165] (2) Multiple single-candidate beam transmission resources can be distributed in one slot or on different slots.

[0166] 2. Frequency domain characteristics:

[0167] (1) Based on the RE pattern and density distribution within a certain RB, each RB in the RBset is the frequency domain RB distribution range of a single candidate beam resource.

[0168] 3. Airspace characteristics:

[0169] (1) The spatial domain transmission filter is the same for a single beam transmission resource.

[0170] 4. Sequence characteristics:

[0171] (1) The RS sequences on each symbol of a single beam transmission resource are generated independently;

[0172] (2) The RS sequence on all symbols except the last symbol in a single beam transmission resource is a repetition of the RS sequence on the last symbol;

[0173] (3) The RS sequence on all symbols except the first symbol on a single beam transmission resource is a repetition of the RS sequence on the first symbol.

[0174] 5. Resource identification characteristics:

[0175] (1) A single beam transfer resource is configured with a resource identifier.

[0176] For example, see Figure 7Multiple single-candidate beam set resources can be configured within a single beam period, and these resources can reside in the same time slot. The RS resource period is 4 slots, and m = 2. Within slot n, two RBsets are configured in the frequency domain, and four symbols are configured in the time domain. Within each RBset, the two symbols numbered 1 and REs of the same padding pattern form a single-candidate beam transmission resource. Within the same RBset, four consecutive symbols numbered 1 and 2 of the same padding pattern form a single-candidate beam set resource. Therefore, RBset 1 contains 8 single-candidate beam transmission resources, forming 4 single-candidate beam set resources. Similarly, RBset 2 contains 8 single-candidate beam transmission resources, forming 4 single-candidate beam set resources. Thus, within slot n (within the RS resource period), there are a total of 8 single-candidate beam set resources, which can be reused by multiple different UEs. See also... Figure 8 When UE uses Figure 7 When performing beam management on the resources of the Beam set shown, up to two beams can be transmitted on a single candidate beam set resource consisting of two single candidate beam transmission resources on a certain RBset of the slot.

[0177] For example, see Figure 9 Multiple single-candidate beam set resources can be configured within a beam period, and these resources can reside on two time slots. A single-candidate beam set resource contains two slots. Within each slot, four symbols are configured in the time domain. Two RBsets are configured in the frequency domain within slot n-1 and slot n. Within each RBset, two symbols numbered 1 and a RE of the same padding pattern form a single-candidate beam transmission resource. Within each RBset, four consecutive symbols numbered 1 and 2, and four consecutive symbols numbered 3 and 4 (a total of eight symbols) form a single-candidate beam set resource. Therefore, RBset1 contains 16 single-candidate beam transmission resources, forming four single-candidate beam set resources. Similarly, RBset2 contains 16 single-candidate beam transmission resources, forming four single-candidate beam set resources. Thus, there are a total of eight single-candidate beam set resources within the RS resource period, which can be reused by multiple different UEs. When a UE uses... Figure 9When performing beam management on the resources of the single candidate beam set shown, up to four beams can be transmitted on the single candidate beam set resources consisting of four single candidate beam transmission resources on a certain RBset of the slot.

[0178] In one exemplary implementation, CSI-RS resources for beam management are configured on logical slots within the SL resource pool. The SL resource pool is configured with two subchannels, and the CSI-RS period is 2. Only one slot's resources are configured for CSI-RS transmission within one CSI-RS transmission period. Four consecutive symbols are configured within one slot for CSI-RS signal transmission. The minimum time interval between the CSI-RS slot and the PSSCH / PSSCH is 0 logical slots. Four consecutive RBsets in the frequency domain are set according to predefined rules.

[0179] Taking slot n+2 as an example, the CSI-RS resources in this slot need to be associated with the four PSCCH / PSSCH transmission resources that meet the minimum latency requirement. According to the timing and frequency domain index, one correspondence is as follows: Figure 10 This satisfies the unique correspondence between RS transmission resources and PSCCH / PSSCH transmission resources. Specifically, there are 4 single-bid candidate beam set resources in slot n+2. Figure 10 In this context, a single candidate beam set resource represents four consecutive symbols in the time domain and a region with a certain padding pattern in the frequency domain. The correspondence between PSCCH / PSSCH and beam set resources is as follows: Figure 10 As indicated by the arrow.

[0180] The SL resource pool is configured with two subchannels. The CSI-RS period is 2. Within one CSI-RS transmission period, only one slot's resources are configured for CSI-RS transmission. Within one slot, four consecutive symbols are configured for CSI-RS signal transmission. The minimum time interval between the CSI-RS slot and the PSSCH / PSSCH is one logical slot. In the frequency domain, one RBset is set according to predefined rules. Figure 11 In this context, a single candidate beam set resource represents a resource with a specific padding pattern within the entire configured RBset in the frequency domain. In the time domain, it represents four consecutive symbols, with one possible correspondence:

[0181] Subband 1 in slot n corresponds to RS resource 4 in slot n+2;

[0182] Subband 2 in slot n corresponds to RS resource 3 in slot n+2;

[0183] Subband 1 in slot n+1 corresponds to RS resource 2 in slot n+2;

[0184] Subband 2 in slot n+1 corresponds to RS resource 1 in slot n+2.

[0185] In one example, for a single candidate beam transport resource of CSI-RS corresponding to a certain PSCCH / PSSCH, based on Figure 10 The structure, such as Figure 11 As shown, it can be used to transmit RS corresponding to the relevant beam. The first symbol is the same as the second symbol's spatial domain transmission filter, and the third symbol is the same as the fourth symbol's spatial domain transmission filter. It can be used to transmit two different beams.

[0186] In one example, for a single candidate beam transport resource of CSI-RS corresponding to a certain PSCCH / PSSCH, based on Figure 10 The structure, such as Figure 12 As shown, it can be used to transmit RS corresponding to the relevant beam. The spatial domain transmission filters on the four symbols are the same and can be used to transmit the same beam.

[0187] In one example, on a single candidate beam transmission resource on a symbol within an RB in the slot where CSI-RS is located, the RS resource transmission location is shown as follows: Figure 13 The RS frequency domain positions on different symbols of a single candidate beam set resource are the same, but the RS sequences on different single candidate beam transmission resources are different. The RS sequence is initialized according to the symbol position of CSI-RS and the CRC of SCI on the associated PSCCH.

[0188] In another exemplary implementation, the CSI-RS resources of the per-transmission resource pool are (pre)configured based on the logical slots on the SL resource pool, and the granularity of the configured CSI-RS resources is: at least one single candidate beam transmission resource in at least one slot, referred to as a single candidate beam set resource. The single candidate beam set resources have no correspondence with the PSCCH / PSSCH resources in the SL resource pool.

[0189] Specifically, the configuration process may include: after determining the transmit resource pool of SL within the BWP on the SL carrier, configuring at least one of the following parameters on the logical slot within the resource pool within one SFN period: CSI-RS transmission timing period P, CSI-RS frequency domain range (including at least one frequency domain RBset), number of single candidate beam set resources within period P, at least one single candidate beam transmission resource above the single candidate beam set resource, minimum time interval G associated with the slot where CSI-RS is located and PSSCH / PSSCH, and parameters related to the single candidate beam transmission resource. The parameters include at least one of the following: period P, slot offset within the single candidate beam set resource, reference signal frequency domain resource block range RBset, reference signal transmission parameters within the resource block. Further, the reference signal transmission parameters include the frequency domain resource cell position within the resource block, the time domain symbol position within the slot, the number of ports, density, code division multiplexing type, power, etc.

[0190] Based on the above configuration parameters, M candidate beam transmission resources can be determined within the CSI-RS transmission cycle. Furthermore, based on the M candidate beam transmission resources, N candidate beam set resources are determined. There is no corresponding relationship between the PSCCH / PSSCH resources in the SL resource pool and the candidate beam set resources.

[0191] Specifically, the location of the single candidate beam set resource used by the UE is determined by explicit signaling. The transmitting UE can transmit signals on the single candidate beam set resource determined on the PSCCH / PSSCH in the transmit resource pool, and the receiving UE can receive and measure signals on the single candidate beam set resource determined on the PSCCH / PSSCH in the receive resource pool.

[0192] It is understood that, unlike the exemplary implementation described above, the single-transmission candidate beam resources configured within the CSI-RS transmission cycle do not have a corresponding mapping relationship with the PSCCH / PSSCH associated with the CSI-RS slot. The single-transmission resources on the slot containing the CSI-RS resources are determined based on configured or pre-configured signaling. The specific single-transmission candidate beam resources used by the UE are dynamically indicated according to explicit signaling, such as... Figure 14 According to the indication information, the subchannel1 resource on slot n corresponds to the single-pass candidate beam resource as follows: Figure 14 The resource shows the area filled with vertical lines in the ellipse. The indication method for this information includes:

[0193] 1. SCI indication alone;

[0194] 2. Indicated solely via MAC CE;

[0195] 3. Instructions via SCI and MAC CE.

[0196] Understandably, the indication information may include the slot index of the beam reference signal, the resource identifier within the time slot of the beam reference signal, the symbol position within the time slot of the beam reference signal, and the frequency domain position.

[0197] It is worth noting that in this embodiment, the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource can be the same as those in the above embodiments, and the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource will not be described again here.

[0198] In another exemplary implementation, the CSI-RS resources of the per-transmit resource pool are (pre)configured based on the logical slots within the BWP on the SL carrier, and the granularity of the configured CSI-RS resources is: at least one single-candidate beam transmission resource within at least one slot, referred to as a single-candidate beam set resource. The PSCCH / PSSCH resources in the SL resource pool can uniquely correspond to at least one single-candidate beam set resource. Different PSCCH / PSSCH resources correspond to different single-candidate beam set resources. The correspondence can be predefined, configured, or pre-configured.

[0199] Specifically, firstly, within one SFN period of the BWP on the SL carrier, after deducting SSB, unavailable slots, and reserved slots from all physical slots, a logical slot within the BWP on the SL carrier is formed. Based on this logical slot, the CSI-RS resource pool of the SL data resource pool is configured. One CSI-RS resource pool is associated with only one SL data resource pool. At least one of the following parameters is configured: CSI-RS time domain resource mapping bitmap, CSI-RS frequency domain range (including at least one frequency domain RBset), at least one single candidate beam transmission resource on the single candidate beam set resource, the minimum time interval G between the slot where the CSI-RS is located and the PSSCH / PSSCH, and parameters related to the single candidate beam transmission resource. Among these parameters, the slot offset within the single candidate beam set resource, the RS frequency domain RB range RBset, and the RS transmission parameters within the RB are further specified. The RS transmission parameters include the frequency domain RE position within the RB, the time domain symbol position within the slot, the number of ports, density, CDM type, power, etc.

[0200] Based on the above configuration parameters, M candidate beam transmission resources are determined within the SFN period. Further, based on the M candidate beam transmission resources, N candidate beam set resources are determined, along with PSCCH / PSSCH transmission resources in the SL data resource pool associated with the candidate beam set resources. Each PSCCH / PSSCH resource in the SL resource pool can uniquely correspond to at least one candidate beam set resource, and different PSCCH / PSSCH resources in different resource pools correspond to different candidate beam set resources.

[0201] The specific location of the single-candidate beam set resource used by the UE is determined based on the explicit signaling and implicit correspondence. The transmitting UE can transmit signals on the single-candidate beam set resource determined on the PSCCH / PSSCH in the transmit resource pool, and the receiving UE can receive and measure signals on the single-candidate beam set resource determined on the PSCCH / PSSCH in the receive resource pool.

[0202] Specifically, within each transmit (tx) of the sidelink BWP, an additional associated CSI-RS resource pool is configured. The number of single-transmission candidate beam set resources within a single SFN period is greater than or equal to the number of PSCCH / PSSCH transmission resources in the transmit resource pool within that SFN period, and a certain correspondence exists. Each PSCCH / PSSCH resource in the SL resource pool can uniquely correspond to at least one single-transmission candidate beam set resource. Different PSCCH / PSSCH resources in different resource pools correspond to different single-transmission candidate beam set resources. The correspondence can be configured or determined by predefined rules. The configuration and correspondence of a resource pool and its corresponding RS resource pool on an SL carrier are as follows: Figure 15 , where RSi in the RS resource pool represents the i-th single-selection beam set resource.

[0203] It is worth noting that in this embodiment, the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource can be the same as those in the above embodiments, and the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource will not be described again here.

[0204] In an exemplary implementation, the CSI-RS resources of the per-transmit resource pool are (pre)configured based on the logical slots within the BWP on the SL carrier, and the granularity of the configured CSI-RS resources is: at least one single-candidate beam transmission resource within at least one slot, referred to as a single-candidate beam set resource. The single-candidate beam set resources have no corresponding relationship with the PSCCH / PSSCH resources in the associated SL resource pool.

[0205] Specifically, firstly, within one SFN period of the BWP on the SL carrier, after deducting the SSB, unusable slots, and reserved slots from all physical slots, a logical slot within the BWP on the SL carrier is formed. Based on this logical slot, the CSI-RS resource pool of the SL data resource pool is configured. One CSI-RS resource pool is associated with only one SL data resource pool, and at least one of the following parameters is configured:

[0206] The CSI-RS time-domain resource mapping bitmap includes the CSI-RS frequency-domain range (containing at least one frequency-domain RBset), the single candidate beam set resource containing at least one single candidate beam transmission resource, the minimum time interval G between the slot where the CSI-RS is located and the PSSCH / PSSCH, and parameters related to the single candidate beam transmission resource. These parameters include: the slot offset within the single candidate beam set resource, the RS frequency-domain RB range RBset, and the RS transmission parameters within the RB. Further, the RS transmission parameters include: the frequency-domain RE position within the RB, the time-domain symbol position within the slot, the number of ports, the density, the CDM type, and the power.

[0207] Based on the above configuration parameters, M single-beam transmission resources are determined within the SFN period. Further, based on the M single-beam transmission resources, N single-beam set resources are determined, as well as PSCCH / PSSCH transmission resources in the SL data resource pool associated with the single-beam set resources. There is no corresponding relationship between the PSCCH / PSSCH resources in the SL resource pool and the single-beam set resources.

[0208] The specific location of the single-candidate beam set resource used by the UE is determined by explicit signaling. The transmitting UE can transmit signals on the single-candidate beam set resource determined on the PSCCH / PSSCH in the transmit resource pool, and the receiving UE can receive and measure signals on the single-candidate beam set resource determined on the PSCCH / PSSCH in the receive resource pool.

[0209] Specifically, within the SL BWP, an associated RS resource pool is configured for each Tx resource pool, which can be resources without mapping relationships. For each Tx resource pool within the SL BWP, an additional CSI-RS resource pool is configured, and the time-domain and frequency-domain resources of the single-transmission resources in the RS resource pool are further configured. Here, RSi in the RS resource pool represents the i-th single-transmission candidate beam set resource. The difference between this implementation and the above exemplary implementation is that the PSCCH / PSSCH resources in the SL resource pool and the single-transmission RS resources in the RS resource pool have no mapping relationship. The specific resources, while satisfying the processing delay, indicate the single-transmission candidate beam set resources corresponding to the PSCCH / PSSCH according to explicit signaling, such as... Figure 16On slot1 and subchannel1, the PSCCH / PSSCH resources can be explicitly signaled to dynamically indicate that RS5 is the corresponding single-candidate beam set resource.

[0210] It is worth noting that in this embodiment, the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource can be the same as those in the above embodiments, and the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource will not be described again here.

[0211] In an exemplary implementation, common CSI-RS resources shared by all transmit resource pools are configured based on logical slots within the BWP on the SL carrier. The granularity of the configured CSI-RS resources is as follows: at least one single candidate beam transmission resource within at least one slot, referred to as a single candidate beam set resource. Each PSCCH / PSSCH resource in each SL resource pool can uniquely correspond to at least one single candidate beam set resource. Different PSCCH / PSSCH resources correspond to different single candidate beam set resources. The correspondence can be predefined, configured, or pre-configured.

[0212] Specifically, firstly, within one SFN period of the BWP on the SL carrier, after deducting SSB, unavailable slots, and reserved slots from all physical slots, a logical slot within the BWP on the SL carrier is formed. Based on this logical slot, a CSI-RS resource pool is configured, with at least one of the following parameters configured: CSI-RS time-domain resource mapping bitmap, CSI-RS frequency-domain range (including at least one frequency-domain RBset), at least one single-candidate beam transmission resource above the single-candidate beam set resource, the minimum time interval G associated between the slot where the CSI-RS is located and the PSSCH / PSSCH, and parameters related to the single-candidate beam transmission resource. Among these parameters, the slot offset within the single-candidate beam set resource, the RS frequency-domain RB range RBset, and RS transmission parameters within the RB are further specified. The RS transmission parameters include: the frequency-domain RE position within the RB, the time-domain symbol position within the slot, the number of ports, the density, the CDM type, and the power, etc.

[0213] Based on the above configuration parameters, M candidate beam transmission resources are determined within the SFN period. Further, based on the M candidate beam transmission resources, N candidate beam set resources are determined, as well as PSCCH / PSSCH transmission resources in the SL data resource pool associated with the candidate beam set resources. Each PSCCH / PSSCH resource in each SL resource pool can uniquely correspond to at least one candidate beam set resource. Different PSCCH / PSSCH resources in different resource pools correspond to different candidate beam set resources.

[0214] The specific location of the single-candidate beam set resource used by the UE is determined based on the explicit signaling and implicit correspondence. For example, a transmitting UE can transmit signals on a single-candidate beam set resource determined on the PSCCH / PSSCH in the transmit resource pool, and a receiving UE can receive and measure signals on a single-candidate beam set resource determined on the PSCCH / PSSCH in the receive resource pool.

[0215] In this embodiment, a common RS resource pool is configured within the SL BWP or SL carrier. The number of single-transmission resources in the RS resource pool is greater than or equal to the number of PSCCH / PSSCH transmission resources across all transmit resource pools within the BWP or carrier, and a definite correspondence exists. That is, a single RS transmission resource in each RS resource pool uniquely corresponds to a PSCCH / PSSCH transmission resource in one SL resource pool. This correspondence can be configured or determined by predefined rules. For example... Figure 17 Within the SFN period, two data resource pools are configured on one SL BWP of one carrier, namely SL resource pool 1 and SL resource pool 2. In addition, in the subframes within the SFN period, after deducting unusable slots such as SSB and DL slots, bitmap mapping is performed on the logical slots to determine a common RS resource pool within the BWP. The frequency domain is set by an RBset, such as... Figure 17 In the RS resource pool, RSi represents the i-th single-selection candidate beam set resource. Furthermore, a relationship such as... Figure 18 This associates RS resources in the RS resource pool within the SFN period with resources in the SL data resource pool configured or pre-configured within the SFN period.

[0216] It is worth noting that in this embodiment, the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource can be the same as those in the above embodiments, and the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource will not be described again here.

[0217] In an exemplary implementation, common CSI-RS resources shared by all transmit resource pools are configured based on logical slots within BWPs on the SL carrier. The granularity of the configured CSI-RS resources is: at least one single candidate beam transmission resource within at least one slot, referred to as a single candidate beam set resource. The single candidate beam set resources do not correspond to the PSCCH / PSSCH resources in the SL resource pool.

[0218] Specifically, firstly, within one SFN period of the BWP on the SL carrier, after deducting the SSB, unusable slots, and reserved slots from all physical slots, a logical slot within the BWP on the SL carrier is formed. Based on this logical slot, a CSI-RS resource pool is configured, with at least one of the following parameters configured:

[0219] The CSI-RS time-domain resource mapping bitmap includes the CSI-RS frequency-domain range (containing at least one RBset in the frequency domain), the previous single-candidate beam set resource, the minimum time interval G between the slot where the CSI-RS is located and the PSSCH / PSSCH, and parameters related to the single-candidate beam transmission resource. These parameters include: the slot offset within the single-candidate beam set resource, the RS frequency-domain RB set, and the RS transmission parameters within the RB. Further, the RS transmission parameters include: the frequency-domain RE position within the RB, the time-domain symbol position within the slot, the number of ports, the density, the CDM type, and the power.

[0220] Based on the above configuration parameters, M candidate beam transmission resources are determined within the SFN period. Further, based on the M candidate beam transmission resources, N candidate beam set resources are determined, as well as PSCCH / PSSCH transmission resources in the SL data resource pool associated with the candidate beam set resources. Each PSCCH / PSSCH resource in each SL resource pool has no corresponding relationship with a candidate beam set resource.

[0221] The specific location of the single-candidate beam set resource used by the UE is determined by explicit signaling. For example, the transmitting UE can transmit signals on the single-candidate beam set resource determined on the PSCCH / PSSCH in the transmit resource pool, and the receiving UE can receive and measure signals on the single-candidate beam set resource determined on the PSCCH / PSSCH in the receive resource pool.

[0222] In this embodiment, a common RS resource pool is configured on the logical slot within the SL BWP on the SL carrier. A common RS resource pool is configured within the SL BWP or the SL carrier, and frequency domain RBset resources for a single candidate beam set resource are further configured. For example... Figure 19 During the SFN period, two data resource pools and one common RS resource pool are configured or pre-configured. There is no implicit correspondence between the single candidate beam set resources in the RS resource pool and the PSCCH / PSSCH in the data resource pool. The single candidate beam set resources in the RS resource pool corresponding to a certain PSCCH / PSSCH are indicated by explicit signaling.

[0223] It is worth noting that in this embodiment, the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource can be the same as those in the above embodiments, and the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource will not be described again here.

[0224] In an exemplary implementation, common CSI-RS resources shared by all transmit resource pools are configured based on physical slots within the BWP on the SL carrier. The granularity of the configured CSI-RS resources is as follows: at least one single candidate beam transmission resource within at least one slot, referred to as a single candidate beam set resource. Each PSCCH / PSSCH resource in each SL resource pool can uniquely correspond to at least one single candidate beam set resource. Different PSCCH / PSSCH resources correspond to different single candidate beam set resources. The correspondence can be predefined, configured, or pre-configured.

[0225] Specifically, on the physical slot within the BWP on the SL carrier, configure at least one of the following parameters:

[0226] The CSI-RS transmission timing period P, the CSI-RS frequency domain range (including at least one RBset in the frequency domain), the number of single candidate beam set resources within period P, the previous single candidate beam transmission resource of the single candidate beam set resource, the minimum time interval G between the slot where the CSI-RS is located and the PSSCH / PSSCH, and parameters related to the single candidate beam transmission resource. Among these parameters are: slot offset within period P or the single candidate beam set resource, RS frequency domain RB range RBset, RS transmission parameters within the RB, and further, RS transmission parameters include: frequency domain RE position within the RB, time domain symbol position within the slot, number of ports, density, CDM type, power, etc.

[0227] Based on the above configuration parameters, M candidate beam transmission resources are determined within the CSI-RS transmission cycle. Further, based on the M candidate beam transmission resources, N candidate beam set resources are determined, along with L PSCCH / PSSCH transmission resources associated with the candidate beam set resources within the cycle. L'(i) is the number of all PSCCH / PSSCH resources in all resource pools within the i-th CSI-RS transmission timing period P within the SFN cycle, and L is the maximum value of L' within the SFN cycle. Each PSCCH / PSSCH resource in each SL resource pool can uniquely correspond to at least one candidate beam set resource. Different PSCCH / PSSCH resources in different resource pools correspond to different candidate beam set resources.

[0228] The specific location of the single-candidate beam set resource used by the UE is determined based on the explicit signaling and implicit correspondence. For example, a transmitting UE can transmit signals on a single-candidate beam set resource determined on the PSCCH / PSSCH in the transmit resource pool, and a receiving UE can receive and measure signals on a single-candidate beam set resource determined on the PSCCH / PSSCH in the receive resource pool.

[0229] In this embodiment, CSI-RS resources for beam management are configured on the BWP of the SL carrier or on the physical slot of the SL carrier. See also Figure 20The RS resource configuration period is 15 physical slots, with an offset of 7 slots within the period. Two consecutive slots within the period are configured to contain a single candidate beam set resource. Two data resource pools are configured or pre-configured within the SFN period. Each PSCCH / PSSCH resource in each data resource pool corresponds one-to-one with the single candidate beam set resource in the RS resource pool composed of the RS resources configured or pre-configured within the SFN period.

[0230] It is worth noting that in this embodiment, the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource can be the same as those in the above embodiments, and the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource will not be described again here.

[0231] In an exemplary implementation, common CSI-RS resources shared by all transmit resource pools are configured based on physical slots within BWPs on SL carriers, and the granularity of the configured CSI-RS resources is: at least one single candidate beam transmission resource within at least one slot, referred to as a single candidate beam set resource. There is no correspondence between the PSCCH / PSSCH resources in each SL resource pool and the single candidate beam set resources.

[0232] Specifically, on the physical slot within the BWP on the SL carrier, at least one of the following parameters is configured: CSI-RS transmission timing period P, CSI-RS frequency domain range (including at least one frequency domain RBset), number of single candidate beam set resources within period P, at least one single candidate beam transmission resource above the single candidate beam set resource, minimum time interval G associated with the slot where CSI-RS is located and PSSCH / PSSCH, and parameters related to the single candidate beam transmission resource. Among these parameters, the parameters include: slot offset within period P or the single candidate beam set resource, RS frequency domain RB range RBset, RS transmission parameters within the RB, and further, RS transmission parameters include: frequency domain RE position within the RB, time domain symbol position within the slot, number of ports, density, CDM type, power, etc.

[0233] Based on the above configuration parameters, M candidate single beam transmission resources are determined within the CSI-RS transmission cycle. Furthermore, N candidate single beam set resources are determined based on the M candidate single beam transmission resources. Each PSCCH / PSSCH resource in each SL resource pool has no corresponding relationship with the candidate single beam set resource.

[0234] The specific location of the single candidate beam set resource used by the UE is determined by explicit signaling. For example, a transmitting UE can transmit signals on the single candidate beam set resource indicated on the PSCCH / PSSCH in the transmit resource pool, and a receiving UE can receive and measure signals on the single candidate beam set resource indicated on the PSCCH / PSSCH in the receive resource pool.

[0235] In this embodiment, there is no implicit correspondence between the single-candidate beam set resources in the RS resource pool and the PSCCH / PSSCH resources in the data resource pool within the SFN period. The single-candidate beam set resources corresponding to specific PSCCH / PSSCH resources are dynamically indicated by explicit signaling. In the previous exemplary embodiment, the number of frequency domain RBsets may need to be implicitly determined within the configured or pre-configured CSI-RS frequency domain range based on the number of PSCCH / PSSCHs associated with the RS resource pool. However, in this exemplary embodiment, because there is no correspondence, the frequency domain RBsets of the RS resources are directly configured or pre-configured.

[0236] It is worth noting that in this embodiment, the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource can be the same as those in the above embodiments, and the characteristics of a single candidate Beam set resource and a single candidate Beam transmission resource will not be described again here.
