Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims the benefit of U.S. Provisional Application No. 63 / 377,434, filed September 28, 2022, and entitled "RESOURCE RESERVATION SUITABLE FOR BEAM-BASED SIDELINK COMMUNICATION FOR BETTER SPATIAL REUSE," which is incorporated herein by reference in its entirety.

[0002] Apparatus and methods consistent with the present disclosure relate generally to communications, and more particularly, to methods, systems, and devices for resource reservation and resource selection in sidelink communications. [Background technology]

[0003] Sidelink communication technology enables direct communication between two or more devices, such as two or more vehicles in vehicle-to-everything (V2X) communication. A first vehicle in sidelink communication may provide its resource reservation information to one or more other vehicles, for example, using periodic broadcast of a sidelink signal, to prevent the other vehicles from selecting the same resource for transmission. This scheme may work well for sidelink communication using low-frequency bands (e.g., 5.9 GHz or lower). However, resource reservation and resource selection for sidelink communication using high-frequency bands (e.g., millimeter wave bands) may be more complex. For high-frequency radio signals with large propagation losses, beamforming with narrow beams is typically used to compensate for the propagation losses. In this case, the resource reservation information of the first vehicle alone may not be sufficient for the other vehicles to accurately and efficiently determine which resources to select or exclude. This is especially true when the first vehicle and the other vehicles are moving. Summary of the Invention [Means for solving the problem]

[0011] Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings, in which like numbers in different drawings represent the same or similar elements unless otherwise noted. The implementations illustrated in the following description of exemplary embodiments do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of systems, apparatus, and methods consistent with aspects related to the present disclosure as set forth in the appended claims.

[0012] FIG. 1 is a flowchart illustrating a method 100 for resource selection in sidelink communication according to an embodiment of the present disclosure. FIG. 2A is a schematic diagram illustrating a resource candidate determination procedure according to the method of FIG. 1 according to an embodiment of the present disclosure. FIG. 2B is a table illustrating a correspondence between SCSs and resource subsets according to the method of FIG. 1 according to an embodiment of the present disclosure. Method 100 may be performed by a UE in sidelink communication. For example, method 100 may be performed by a vehicle in V2X communication. Method 100 may be performed in a mode using orthogonal frequency division multiplexing (OFDM) at the physical (PHY) layer for sidelink communication. An example of such a mode is described in 3GPP Release 16 / 17 5G NR-V2X PC5 mode 2.

[0013] As shown in Figure 2A, in this mode, the time-frequency radio resource is divided into slots in the time domain and subchannels in the frequency domain. In one embodiment, this mode is 15*2 μkHz SCS may be supported, where μ is the OFDM numerology μ∈{0,1,2,3,4}. For sub-6 GHz frequencies, SCSs of 15, 30, and 60 kHz (i.e., μ∈{0,1,2}) may be supported, and for frequencies above 6 GHz, SCSs of 60, 120, and 240 kHz (i.e., μ∈{2,3,4}) may be supported. Each slot is ½ μ ms in length and consists of 14 OFDM symbols. Each subchannel may consist of multiple consecutive physical resource blocks (PRBs), each PRB being 180*2 μ occupies 15*2 kHz μ It consists of 12 subcarriers with an SCS of 10 kHz. The size of the subchannels (i.e., the number of PRBs per subchannel) is configurable or preconfigurable. To support multiple SCSs and different Doppler spreads, multiple demodulation reference signals (DMRS) are used. Each UE transmits the first stage SCI on the physical sidelink control channel (PSCCH) and data (e.g., transport blocks (TBs)). It also transmits the second stage SCI on the physical sidelink shared channel (PSSCH). Hybrid automatic repeat request (HARQ) feedback (e.g., acknowledgement (ACK) / negative acknowledgment (NACK) or NACK only) may be transmitted on the physical sidelink feedback channel (PSFCH).

[0014] FIG. 2B illustrates a graph of the SCS and the sensing and selection window parameters (T SL proc,0 and T SL proc,1 For example, when the SCS is 15 kHz, as shown in the second and third columns of Figure 2B, T SL proc,0 corresponds to 1 ms, and T SL proc,1 corresponds to 3 ms. As another example, if the SCS is 30 kHz, T SL proc,0 corresponds to 0.5 ms, and T SL proc,1 corresponds to 2.5ms.

[0015] 1, the method 100 includes step 102 of performing channel sensing (e.g., background sensing or any other type of full or partial sensing). For example, as shown in FIG. 2A, the UE may perform a sensing window T sensing (For example, T sensing =[T0,T SL proc,0 ], where T0=100 or 1100 ms, and T SL proc,0 2B) to collect resource reservation information of other UEs. Channel sensing with a 100 ms sensing window may be for aperiodic traffic, and channel sensing with an 1100 ms sensing window may be for periodic traffic.

[0016] The method 100 includes step 104 of collecting resource reservation information of other UEs and measuring corresponding sidelink-reference signal received power (SL-RSRP). For example, as shown in FIG. 2A, the UE may perform channel sensing within a sensing window, collect resource reservation information of other UEs based on decoding of the SCI, and identify candidate resources. In one embodiment, the UE first decodes the SCI to perform channel sensing and obtain information for receiving packets of other UEs. The decoding of the SCI may include two stages: a first-stage SCI (SCI format 1-A) and a second-stage SCI (SCI format 2-A or 2-B) as defined in the 3GPP standard. The first-stage SCI may carry resource reservation information for future transmissions, information about resource allocation, a modulation and coding scheme (MCS) for the PSSCH, a DMRS pattern, and a second-stage SCI format. The second-stage SCI may carry control information for HARQ procedures, source / destination IDs, distance-based groupcast information (e.g., a UE's zone ID and coverage requirements), and the like. When performing resource selection or reselection, the UE may avoid using time and / or frequency resources reserved by other UEs based on the resource reservation information included in the first-stage SCI.

[0017] The method 100 includes determining candidate resources by excluding occupied, reserved, and / or unmonitored resources 106. For example, the UE may exclude unmonitored slots from a selection window T (e.g., T=[T1, T2], where 0≦T1≦T SL proc,1 ms and T SL proc,1is given in FIG. 2B, where T2 may be set based on the remaining packet delay window. The UE may not be able to sense unmonitored slots in the sensing window, for example, due to its own transmission (e.g., half-duplex constraints). The UE may further exclude resources occupied or reserved by other UEs from the selection window if the corresponding SL-RSRP exceeds a configured or pre-configured SL-RSRP exclusion threshold. After resource exclusion, the number of candidate resources may be at least X% of the total number of resources in the selection window. If not, the UE may increase the SL-RSRP exclusion threshold, for example, by 3 dB, until at least X% of the resources are obtained. X may be configured or pre-configured from {20, 35, 50}%.

[0018] The method 100 includes a step 108 of selecting a resource from among the candidate resources. The selection may be a random selection. For example, as shown in FIG. 2A, the UE may select a resource from among the candidate resources within a selection window. The selected frequency resource may be used multiple times at fixed time intervals in the case of semi-persistent scheduling (SPS) or only once in the case of one-shot transmission (OST).

[0019] In one embodiment, method 100 may utilize a UE-to-UE cooperation scheme in which one or more other UEs transmit cooperative information regarding resources to the UE, and the UE utilizes the information for its resource selection or reselection. The UE-to-UE cooperation scheme may include a first UE-to-UE cooperation scheme and a second UE-to-UE cooperation scheme. According to the first UE-to-UE cooperation scheme, the UE may receive from one or more other UEs indications of resources that are preferred to be included or excluded from the resources selected or reselected by the UE. In one embodiment, if the resource indication indicates inclusion of given resources, the UE may rely solely on those resources if the indication does not support sensing and / or resource exclusion. In one embodiment, the UE may also combine the resource indication with resources identified by its own sensing procedure before making a final selection. The UE may receive the indication via a medium access control (MAC) control element (CE) and / or a second-stage SCI. According to the second UE-to-UE cooperation scheme, the UE may receive an indication that resources reserved for the UE's transmission will or may conflict with transmissions from other UEs. In this case, the UE reselects a new resource. The UE may receive the indication via the PSFCH. The UE may use a mapping table that defines mapping rules between the PSSCH allocation (e.g., one or more slots and subchannels) and the PSFCH resources. Using the mapping table, the UE (and the transmitting UE) can determine the PSSCH allocation to which the information in the PSFCH resource refers. If more than one subchannel is reserved in the PSSCH, multiple PSFCH resources may be used. The mapping table may be predefined, preconfigured in the UE, or configured by a network node.

[0020] The method 100 includes a step 110 of checking resource availability based on re-evaluation and / or pre-emption of the selected resource. This step may be performed for late-arriving packets (e.g., aperiodic packets) after resource selection and before packet transmission.

[0021] Method 100 includes step 112 of determining whether resource reselection is required. If it is determined that resource reselection is required, the method may repeat from step 104. On the other hand, if it is determined that resource reselection is not required, the method may proceed to step 114 of transmitting a packet based on an SPS or an OST. The packet may be an initial packet or a retransmission packet. The UE may also retransmit the packet multiple times (e.g., HARQ retransmissions) with or without feedback from the receiving UE to improve the reliability of the transmission. After step 114, method 100 may repeat again from step 102.

[0022] 3A is a schematic diagram illustrating transmission of resource reservation information in sidelink communication according to an embodiment of the present disclosure, and FIG. 3B is a schematic diagram illustrating resource collision avoidance using the resource reservation information in the sidelink communication of FIG. 3A according to an embodiment of the present disclosure. Referring to FIG. 3A and FIG. 3B, a sidelink communication system includes UE 302, UE 304, UE 306, UE 308, and UE 310. For simplicity, FIG. 3A only shows UE 302 and UE 304. In sidelink communication, UE 3B ) in the sidelink communication system may receive the packet, decode the SCI received from the UE 302, and obtain the resource reservation information of the UE 302. The UE 302 may be a transmitting (Tx) UE (e.g., an omnidirectional Tx UE), and the UE 304 may be a receiving (Rx) UE (e.g., an omnidirectional Rx UE). The UE 302 may reserve resources for data transmission. The UE 302 may also encode resource reservation information into an SCI and transmit the SCI along with the packet, e.g., using one or more omnidirectional antennas. The SCI may include time and / or frequency resources for retransmissions scheduled by the UE 302, SPS time intervals, and other information. Other UEs in the sidelink communication system (UE 306, UE 308, and UE 310 in FIG. 3B ) may receive the packet, decode the SCI received from the UE 302, and obtain the resource reservation information of the UE 302. Because UE 306, UE 308, and UE 310 have resource reservation information for UE 302, they may avoid using time and / or frequency resources reserved by UE 302 when performing resource selection or reselection, thus avoiding resource collisions.

[0023] The resource reservation and resource selection mechanisms described above may be useful for sidelink communications based on low frequency bands, such as omnidirectional FR1 signals. In this disclosure, FR1 is defined as the frequency range of 410-7125 MHz (including sub-6 GHz frequency bands). However, resource reservation and resource selection for sidelink communications based on higher frequency bands (e.g., FR2) are more complex. In this disclosure, FR2 is defined as two frequency subranges: FR2-1 from 24250-52600 MHz and FR2-2 from 52600-71000 MHz (including mmWave spectrum). For high frequency radio signals with large propagation losses, beamforming with narrow beams is typically used to provide sufficient beamforming gain to compensate for the propagation losses.

[0024] FIG. 4 is a schematic diagram illustrating sidelink beamforming in a communication system according to one embodiment of the present disclosure. Referring to FIG. 4 , the communication system 400 includes a first UE (UE 402) and a second UE (UE 404) communicating with each other via sidelink communication using a high frequency band signal (e.g., FR2). For example, the sidelink communication may be V2X communication, where both the UE 402 and the UE 404 are vehicles. In the communication system 400, the UE 402 may be a Tx UE, and the UE 404 may be a Rx UE. Because the sidelink communication between the UE 402 and the UE 404 uses a high frequency signal, sidelink beamforming may be used to transmit the sidelink signal to the UE 404. The direction of the Tx beam 406 from the UE 402 and the Rx beam 408 from the UE 404 can be aligned. In this disclosure, the terms "beam alignment" and "beamforming" are used interchangeably. The above-described resource reservation and resource selection mechanisms designed for sidelink communications in a low frequency band (e.g., FR1) may not be applicable to resource reservation and resource selection for high frequency sidelink communications, especially when both UEs are moving. At least one embodiment of the present disclosure is directed to resource reservation and resource selection in high frequency band-based sidelink communications taking into account the locations of the Tx and Rx UEs and the Tx / Rx beam directions.

[0025] 5A is a schematic diagram illustrating side information exchange in low frequency sidelink communication according to an embodiment of the present disclosure, and FIG. 5B is a schematic diagram illustrating side information-assisted beam alignment in sidelink communication according to an embodiment of the present disclosure. Referring to FIG. 5A and FIG. 5B, a communication system includes a first UE (UE 1) and a second UE (UE 2) communicating with each other via sidelink communication. 5A , the sidelink communication may include a first UE (UE 502) and a second UE (UE 504). For example, the sidelink communication may be V2X communication, and the UE 502 and the UE 504 are both vehicles. In the communication system, the UE 502 may be a Tx UE, and the UE 504 may be an Rx UE. In one embodiment, as shown in FIG. 5A , the UE 502 and the UE The UEs 502 and 504 exchange side information using low frequency band signals (e.g., below 6 GHz), for example, using omnidirectional antennas. The exchanged side information may include at least one of the current position, velocity, acceleration, or heading of the transmitting UE. The UEs 502 and 504 may exchange side information periodically (e.g., every 100 milliseconds). For example, the UEs 502 and 504 may exchange side information by periodically broadcasting a sidelink signal such as a cooperative awareness message (CAM) or a basic safety message (BSM).

[0026] In one embodiment, after exchanging side information, for beam-based sidelink communication, UE 502 and UE 504 may perform beam alignment using a limited number of candidate training pairs, e.g., three beam pairs, as shown in Figure 5B. The selected three beam pairs may cover a specific angle space determined based on the exchanged CAM or BSM information, rather than the entire angle space. In this way, the overhead of beam alignment may be reduced.

[0027] FIG. 6 is a schematic diagram illustrating resource reservation information for beam-based sidelink communication according to an embodiment of the present disclosure. Referring to FIG. 6, a communication system includes a first UE (UE 602) and a second UE (UE 603) communicating with each other via beam-based sidelink communication. The sidelink communication may be V2X communication, and the UE 602 and the UE 604 are both vehicles. In the communication system, the UE 604 may be a Tx UE, and the UE 602 may be an Rx UE. In one embodiment, the UE 604 transmits resource reservation information including future beam information for future transmissions (e.g., Tx beam and Rx beam indicators, direction, and / or beam width) and / or future estimated location information of UE 602 and / or UE 604 for anticipated future transmissions. UE 604 may transmit the resource reservation information via the SCI. UE 604 may obtain the future beam information for future transmissions (e.g., Tx beam and Rx beam indicators, direction, and / or beam width) and future estimated location information of UE 602 and / or UE 604, for example, based on previous communications with UE 602. For example, UE 604 may receive the Society of Automotive Engineers (SAE) BSM and / or European Telecommunications Standards Institute (ETSI) BSM transmitted from UE 602. The UE 604 may estimate a future location of the UE 602 using information from the BSM or CAM. The BSM or CAM information may include at least one of the UE 602's current location, velocity, acceleration, or future planned trajectory. Alternatively or additionally, the UE 604 may estimate its future location at the time the future transmission occurs and transmit that information to the UE 602 at the PHY layer, MAC layer, or higher layer. The higher layer may include at least one of the network layer, transport layer, or application layer.

[0028] The UE 604 may transmit the resource reservation information via omnidirectional sidelink communication in a low frequency band (e.g., 5.9 GHz) or via beam-based sidelink communication in a high frequency band (e.g., mmWave) using wide beams or beam sweeping to cover a sufficient angular space. The UE 604 may transmit the resource reservation information via SCI at the PHY layer to facilitate other UEs taking future beam and location information into account in resource sensing procedures. Alternatively or additionally, the UE 604 may transmit the resource reservation information using the MAC CE and / or higher layers at the MAC layer.

[0029] Based on this resource reservation information, other UEs (not shown in FIG. 6) in the communication system may avoid using the reserved time and / or frequency resources and Tx and / or Rx beams that may cause interference to reserved transmissions at UE 604 and UE 602. In this manner, spatial reuse and improved reliability in beam-based sidelink communications may be achieved.

[0030] 7 is a schematic diagram illustrating an example of a resource collision avoidance system 700 according to an embodiment of the present disclosure. Referring to FIG. 7, the communication system 700 includes a UE 702 (e.g., a Tx UE) and a UE 704 (e.g., an Rx UE) that communicate with each other via beam-based sidelink communication, and a UE 706 (e.g., a Tx UE) and a UE 708 (an Rx UE) that also communicate with each other via beam-based sidelink communication. The system 700 also includes other UEs, such as a UE 710. As shown in FIG. 7, the UE The direction of the Tx beam of UE 710 is substantially the same as the direction of the Tx beam of UE 702. Referring to FIG. 7, UE 702 transmits information such as future beam information (e.g., Tx and Rx beam indicators, directions, and / or beam widths), future estimated locations of UE 702 and / or UE 704, etc. Based on this information, UE 710 avoids using overlapping resources for Tx beam transmission, which may cause interference in beam-based sidelink communications between UE 702 and UE 704. Meanwhile, the directions of the Tx and Rx beams of UE 706 and UE 708 are different from the directions of the Tx and Rx beams of UE 702 and UE 704. Therefore, because the beam directions are different, transmission and reception between the UEs 706 and 708 is unlikely to interfere with communication between the UEs 702 and 704, allowing the UEs 706 and 708 to perform beam-based sidelink communication even using resources that overlap with those of the UEs 702 and 704.

[0031] FIG. 8 is a schematic diagram illustrating a method for indicating an estimated location of a future UE according to an embodiment of the present disclosure. In one embodiment, as shown in FIG. 8, a plurality of two-dimensional (2D) zones are established. Each zone has a unique identification (ID) number (e.g., 1, 2, 3, 4, ..., 132). For example, a zone with an ID of 1 is established. Each dimension (e.g., width and length) L of the zone is also established from, for example, 1, 5, 10, 20, 30, 40, 50 m (e.g., when each zone is two-dimensional (2D) and has a substantially square shape). The zone dimension L can be any other value, such as less than 1 m or more than 50 m. In this manner, the estimated location of the future UE is indicated using the ID of the zone where the UE is expected to be located. In one embodiment, instead of 2D zones, 3D zones corresponding to 3D beamforming (i.e., horizontal and vertical beamforming) are also established. In one embodiment, the future predicted position is calculated using a simple estimation technique based on the current position, speed, and orientation, for example, assuming constant speed and orientation, or using a more advanced estimation technique that takes into account vehicle dynamics. Alternatively or additionally, the future position may be estimated and represented at the application layer by an SAE BSM or ETSI CAM (e.g., current position, speed, orientation, future planned trajectory, etc.).

[0032] FIG. 9A is a schematic diagram illustrating a method for indicating estimated future beam information according to an embodiment of the present disclosure, and FIG. 9B is a schematic diagram illustrating another method for indicating estimated future beam information according to an embodiment of the present disclosure. In one embodiment, the beam information (beam direction and beam width) of an estimated future beam (Tx beam or Rx beam) is indicated using 2D azimuth beam information. For example, as shown in FIGS. 9A and 9B, multiple beam zones are set in a 2D polar coordinate system. The total number of beam zones may be set by the network or may be pre-configured in the UE. In one embodiment, as shown in FIG. 9A, the beam information (beam direction and beam width) of an estimated future beam is indicated using a beam start ID (A) and a beam end ID (B). In another embodiment, as shown in FIG. 9B, the beam information (beam direction and beam width) of an estimated future beam is indicated using a beam start ID (A) and a beam zone number (e.g., 3).

[0033] In one embodiment, for a given beam (Tx beam or Rx beam), the corresponding beam zone may be selected based on some criteria, such as a beam ID that overlaps with the given beam in terms of a particular beam width metric (e.g., beam half-width). The reference point (or origin) and (x, y) directions of the coordinate system may be specified. For example, as shown in FIGS. 9A and 9B, the reference point may be set as the center of a 2D zone. In one embodiment, absolute (x, y) directions are used to indicate the estimated future beam direction. For example, the x and y directions may be set to west and north, respectively. In other embodiments, relative (x, y) directions are used. For example, the x and y directions relative to the vehicle's heading are used to indicate the future beam direction. In one embodiment, instead of 2D polar coordinates, a 3D polar coordinate system may be used to include vertical beam information, which can be useful for 3D beamforming (e.g., horizontal and vertical beamforming).
