[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 377,434, filed on September 28, 2022, entitled “ESOURCE RESERVATION SUITABLE FOR BEAM-BASED SIDELINK COMMUNICATION FOR BETTER SPATIAL REUSE,” the entire contents of which are incorporated herein by reference. Technical Field

[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 Art

[0003] Sidelink communication technology enables direct communication between two or more devices (e.g., two or more vehicles in vehicle-to-everything (V2X) communication). The first vehicle in the sidelink communication can provide its resource reservation information to one or more other vehicles, for example using periodic broadcasts of sidelink signals, so that other vehicles can avoid selecting the same resources for transmission. This scheme can work well for sidelink communications using low frequency bands (e.g., 5.9 GHz or lower). However, resource reservation and resource selection for sidelink communications using high frequency bands (e.g., millimeter wave bands) may be more complex. For high-frequency radio signals that suffer from high 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 other vehicles to accurately and efficiently determine the resources to be selected or excluded. This is especially the case when the first vehicle and the other vehicles are moving. Summary of the invention

[0011] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings, in which the same reference numerals in different figures represent the same or similar elements unless otherwise indicated. The implementations set forth in the following description of the exemplary embodiments do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of systems, devices, and methods consistent with various aspects of the present disclosure as described in the appended claims.

[0012] Figure 1 is a flow chart illustrating a method 100 for resource selection in sidelink communications; Figure 2A It shows that according to Figure 1 A schematic diagram of a resource candidate determination process of the method; and Figure 2B It is to show that some embodiments consistent with the present disclosure are based on Figure 1 A table of correspondence between the SCS and resource subsets of the method. Method 100 can be performed by a UE in sidelink communication. For example, method 100 can be performed by a vehicle in V2X communication. Method 100 can be performed in a mode that adopts Orthogonal Frequency Division Multiplexing (OFDM) for sidelink communication at the physical (PHY) layer. An example of this mode is 3GPP Release 16 / 17 5G NR-V2X PC5 Mode 2.

[0013] like Figure 2A As shown in , in this mode, the time-frequency radio resources are divided into time slots in the time domain and sub-channels in the frequency domain. In one embodiment, this mode can support 15*2 μ kHz SCS, where μ is the OFDM value, μ∈{0,1,2,3,4}. For sub-6 GHz frequencies, 15 kHz, 30 kHz, and 60 kHz (i.e., μ∈{0,1,2}) SCSs are supported, while for frequencies above 6 GHz, 60 kHz, 120 kHz, and 240 kHz (i.e., μ∈{2,3,4}) SCSs are supported. Each time slot is 1 / 2 μ ms length and consists of 14 OFDM symbols. Each subchannel can be composed of multiple consecutive physical resource blocks (PRBs), where each PRB occupies 180*2 μ kHz, and consists of 12 with 15*2 μkHz SCS subcarrier composition. The size of the subchannel (i.e., the number of PRBs per subchannel) is configurable or preconfigurable. To support multiple SCSs and different Doppler spreads, multiple demodulation reference signal (DMRS) density options are supported (2 to 4 DMRS symbols per time slot). Each UE can transmit the first stage SCI and data (e.g., transport block (Transport Block, TB)) in the physical sidelink control channel (Physical Sidelink Control Channel, PSCCH), and the second stage sidelink control information (Sidelink Control Information, SCI) in the physical sidelink shared channel (Physical Sidelink Shared Channel, PSSCH). Hybrid Automatic Repeat Request (HARQ) feedback (e.g., Acknowledgement (ACK) / Negative Acknowledgement (NACK), or only NACK) can be transmitted in the physical sidelink feedback channel (Physical Sidelink Feedback Channel, PSFCH).

[0014] Figure 2B The SCS and the sensing window and the selection window (T SL proc,0 and T SL proc,1 ) parameters. For example, when SCS is 15kHz, Figure 2B As shown in the second and third columns, T SL proc,0 corresponds to 1ms, while T SL proc,1 Corresponds to 3ms. For another example, when SCS is 30kHz, T SL proc,0 corresponds to 0.5ms, while T SL proc,1 Corresponding to 2.5ms.

[0015] Return to see Figure 1 , the method 100 includes: step 102, performing channel sensing (eg, background sensing or any other type of full sensing or partial sensing). Figure 2A As shown in FIG. , the UE can sensing (For example, T sensing=[T0,T SL proc,0 ], where T0 = 100 or 1100 ms, and T SL proc,0 exist Figure 2B Channel sensing is performed in the UE to collect resource reservation information of other UEs. Channel sensing with a sensing window of 100 ms can be used for non-periodic services, while channel sensing with a sensing window of 1100 ms can be used for periodic services.

[0016] The method 100 includes: step 104, collecting resource reservation information of other UEs and measuring the corresponding sidelink reference signal received power (SL-RSRP). Figure 2A As shown in , the UE can perform channel sensing in the sensing window and collect resource reservation information of other UEs based on SCI decoding to identify candidate resources. In one embodiment, in order to perform channel sensing and obtain information to receive packets from other UEs, the UE first decodes the SCI. SCI decoding may include two stages: the first stage SCI (SCI format 1-A) and the second stage SCI (SCI format 2-A or 2-B) as defined in the 3GPP specification. The first stage SCI may carry resource reservation information for future transmissions, information related to resource allocation, modulation and coding scheme (MCS) for PSSCH, DMRS mode, and second stage SCI format, etc. The second stage SCI may carry control information for HARQ processes, source / destination IDs, information for distance-based groupcast (e.g., UE area ID and communication range requirements), etc. Based on the resource reservation information contained in the first stage SCI, the UE may avoid using time and / or frequency resources reserved by other UEs when the UE performs resource selection or reselection.

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

[0018] Method 100 includes: step 108, selecting a resource from the candidate resources. The selection may be a random selection. For example, Figure 2A As shown in , the UE can select a resource from the candidate resources in the selection window. The selected frequency resource can be used multiple times for Semi-Persistent Scheduling (SPS) at fixed time intervals or only once for One-Shot Transmission (OST).

[0019] In some embodiments, the method 100 may utilize an inter-UE coordination scheme in which one or more other UEs send coordination information about resources to the UE, and the UE utilizes the information to perform its resource selection or reselection. The inter-UE coordination scheme may include a first inter-UE coordination scheme and a second inter-UE coordination scheme. According to the first inter-UE coordination scheme, the UE may receive from one or more other UEs an indication of resources that are preferably to be included in the selected or reselected resources of the UE or that are preferably to be excluded. In one embodiment, when the indication of the resource indicates that a given resource is included, if the indication does not support sensing and / or resource exclusion, the UE may rely only on these resources. In one embodiment, before making a final selection, the UE may also combine the indication of the resource with the resource identified by its own sensing process. 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 inter-UE coordination scheme, the UE may receive an indication that the resources reserved for the UE's transmission will or may conflict with the transmission from another UE. In this case, the UE may reselect new resources. The UE may receive the indication via the PSFCH. The UE may use a mapping table that defines the mapping rules between PSSCH allocations (e.g., one or more time slots and subchannels) and PSFCH resources. Using the mapping table, the UE (and the transmitter UE) may determine the PSSCH allocation to which the information in the PSFCH resource refers. When more than one subchannel is reserved in the PSSCH, multiple PSFCH resources may be used. The mapping table may be predefined, preconfigured at the UE, or configured by a network node.

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

[0021] The method 100 includes: step 112, determining whether resource reselection is required. If it is determined that resource reselection is required, the method can iterate from step 104. On the other hand, if it is determined that resource reselection is not required, the method can continue with: step 114, transmitting a packet based on the SPS or the OST. The packet can be an initial packet or a retransmitted packet. The UE can 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, the method 100 can be repeated from step 102.

[0022] Figure 3Ais a schematic diagram illustrating transmission of resource reservation information in sidelink communication; and Figure 3B It is to illustrate the use of some embodiments consistent with the present disclosure Figure 3A Schematic diagram of resource conflict avoidance for resource reservation information in sidelink communication. Figure 3A and Figure 3B , the sidelink communication system includes UE 302, UE 304, UE 306, UE 308 and UE 310. For simplicity, Figure 3A Only UE 302 and UE 304 are shown. In sidelink communication, UE 302 is a transmitter (Tx) UE (e.g., an omni-directional Tx UE) and UE 304 is a receiver (Rx) UE (e.g., an omni-directional Rx UE). UE 302 can reserve resources for data transmission. UE 302 can also encode resource reservation information into the SCI and transmit the SCI together with the packet, for example, using one or more omni-directional antennas. The SCI can include time and / or frequency resources, SPS time intervals, and other information for retransmissions scheduled at UE 302. Other UEs ( Figure 3B UE 306, UE 308, and UE 310) can receive the packet, decode the SCI received from UE 302, and obtain the resource reservation information of UE 302. Since UE 306, UE 308, and UE 310 have the resource reservation information of UE 302, they can avoid using the time and / or frequency resources reserved by UE 302 when they perform resource selection or reselection. In this way, resource conflicts are avoided.

[0023] The above-mentioned resource reservation and resource selection mechanisms can be helpful for sidelink communications based on low frequency bands (e.g., omnidirectional FR1 signals). In the present disclosure, FR1 is defined as a frequency range of 410Mhz to 7125Mhz (including sub-6GHz spectrum). However, resource reservation and resource selection for sidelink communications based on high frequency bands (e.g., FR2) are more complicated. In the present disclosure, FR2 is defined as two frequency sub-ranges: FR2-1 from 24250MHz to 52600MHz, and FR2-2 from 52600MHz to 71000MHz (including millimeter wave spectrum). For high-frequency radio signals that suffer from high propagation losses, beamforming with narrow beams is typically used to provide sufficient beamforming gain to compensate for the propagation losses.

[0024] Figure 4 is a schematic diagram illustrating sidelink beamforming in a communication system consistent with some embodiments of the present disclosure. Figure 4, the communication system 400 includes a first UE (UE 402) and a second UE (UE 404) that communicate with each other via sidelink communication using a high frequency band signal (e.g., FR2). For example, the sidelink communication may be V2X communication, and both UE 402 and UE 404 are vehicles. In the communication system 400, UE 402 may be a Tx UE, and UE 404 may be an Rx UE. Since the sidelink communication between UE 402 and UE 404 uses a high frequency signal, sidelink beamforming is used so that the Tx beam 406 from UE 402 and the Rx beam 408 from UE 404 can be aligned. The terms "beam alignment" and "beamforming" are used interchangeably in the present disclosure. The above-mentioned resource reservation and resource selection mechanisms designed for low frequency band (e.g., FR1) sidelink communication may not be applicable to resource reservation and resource selection in high frequency sidelink communication, especially when both UEs are moving. At least some embodiments of the present disclosure relate to resource reservation and resource selection in sidelink communication based on a high frequency band by considering the locations of Tx and Rx UEs and Tx / Rx beam directions.

[0025] Figure 5A is a schematic diagram showing side information exchange in low frequency sidelink communication; and Figure 5B is a schematic diagram illustrating side information assisted beam alignment in sidelink communications consistent with some embodiments of the present disclosure. Figure 5A and Figure 5B , the communication system includes a first UE (UE 502) and a second UE (UE 504) communicating with each other via sidelink communication. For example, the sidelink communication may be V2X communication, and both UE 502 and UE 504 are vehicles. In the communication system, UE 502 may be a Tx UE, and UE 504 may be an Rx UE. In some embodiments, as Figure 5A As shown, UE 502 and UE 504 use, for example, omnidirectional antennas to exchange side information using low-band signals (e.g., below 6 GHz). The exchanged side information may include at least one of the current position, speed, acceleration, or heading of the transmitting UE. UE 502 and UE 504 may periodically (e.g., every 100 ms) exchange side information. For example, UE 502 and UE 504 may exchange side information by periodically broadcasting sidelink signals (such as, Cooperative Awareness Message (CAM) or Basic Safety Message (BSM)).

[0026] In some embodiments, after the side information exchange, for beam-based sidelink communication, UE 502 and UE 504 may use a limited (restricted) number of candidate training pairs (e.g., three beam pairs, such as Figure 5B The selected three beam pairs may cover a certain angle space determined based on the exchanged CAM or BSM information, rather than the entire angle space. In this way, the beam alignment overhead may be reduced.

[0027] Figure 6 is a schematic diagram showing resource reservation information for beam-based sidelink communication consistent with some embodiments of the present disclosure. Figure 6 , a communication system includes a first UE (UE 602) and a second UE (UE 604) communicating with each other via a beam-based sidelink communication. The sidelink communication may be V2X communication, and both UE 602 and UE 604 are vehicles. In the communication system, UE 604 may be a Tx UE, and UE 602 may be an Rx UE. In some embodiments, UE 604 transmits resource reservation information, which includes future beam information for future transmissions (e.g., indicators, directions, and / or beam widths of Tx beams and Rx beams) and / or estimated future position information of UE 602 and / or UE 604 for expected future transmissions. UE 604 may transmit the resource reservation information via SCI. UE 604 may obtain future beam information (e.g., indicators, directions, and / or beam widths of Tx and Rx beams) for future transmissions, and estimated future position information of UE 602 and / or UE 604, for example, based on previous communications with UE 602. For example, UE 604 may estimate the future position of UE 602 by utilizing information in a Society of Automotive Engineers (SAE) BSM and / or a European Telecommunications Standards Institute (ETSI) CAM sent by UE 602. The information in the BSM or CAM may include at least one of the current position, velocity, acceleration, or future planned trajectory of UE 602. Alternatively or additionally, UE 604 may estimate its future position when future transmissions occur, and send the information to UE 602 at a PHY layer, a MAC layer, or a higher layer. The higher layer may include at least one of the following: a network layer, a transport layer, or an application layer.

[0028] UE 604 may transmit resource reservation information via omnidirectional sidelink communication at a low frequency band (e.g., 5.9 GHz) or via beam-based sidelink communication at a high frequency band (e.g., a millimeter wave band) using a wide beam or beam scanning to cover sufficient angular space. UE 604 may transmit resource reservation information via SCI at the PHY layer so that other UEs may consider future beam and location information during resource sensing. Alternatively or additionally, UE 604 may transmit resource reservation information using MAC CE at the MAC layer and / or higher layers.

[0029] Based on the resource reservation information, other UEs in the communication system ( Figure 6 604 and 602. In this way, improved spatial reuse and reliability in beam-based sidelink communications may be achieved.

[0030] Figure 7 is a schematic diagram illustrating an exemplary resource conflict avoidance system 700 consistent with some embodiments of the present disclosure. Figure 7 , the communication system 700 includes a UE 702 (e.g., Tx UE) and a UE 704 (e.g., Rx UE) communicating with each other via beam-based sidelink communication, and a UE 706 (e.g., Tx UE) and a UE 708 (Rx UE) also communicating with each other via beam-based sidelink communication. The system 700 also includes other UEs, such as a UE 710. Figure 7 As shown, the direction of the Tx beam of UE 710 is substantially the same as the direction of the Tx beam of UE 702. Figure 7 , UE 702 transmits information such as future beam information (e.g., indicators, directions, and / or beam widths of Tx and Rx beams), estimated future locations of UE 702 and / or UE 704. Based on the information, UE 710 avoids using overlapping resources in Tx beam transmission, because this may cause interference to beam-based sidelink communication between UE 702 and UE 704. On the other hand, Tx beam and Rx beam directions of UE 706 and UE 708 are different from Tx beam and Rx beam directions of UE 702 and UE 704. Therefore, even if resources overlapping with those of UE 702 and UE 704 are used, UE 706 and UE 708 are allowed to perform beam-based sidelink communication, because due to different beam directions, transmission / reception between UE 706 and UE 708 is less likely to interfere with communication between UE 702 and UE 704.

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

[0032] Fig. 9A is a schematic diagram showing a method for indicating estimating future beam information, and Fig. 9B is a schematic diagram showing another method for indicating estimated future beam information consistent with some embodiments of the present disclosure. In some embodiments, 2D azimuth beam information is used to indicate beam information (beam direction and beam width) of an estimated future beam (Tx beam or Rx beam). For example, Fig. 9A and Fig. 9B As shown, multiple beam regions are configured in a 2D polar coordinate system. The total number of beam regions may be configured by the network or preconfigured at the UE. Fig. 9A As shown, the beam start ID (A) and the beam end ID (B) are used to indicate the beam information (beam direction and beam width) for estimating the future beam. Fig. 9B As shown, beam information (beam direction and beam width) for estimating a future beam is indicated using a beam start ID (A) and the number of beam regions (eg, 3).

[0033] In some embodiments, for a given beam (Tx beam or Rx beam), the corresponding beam region may be selected based on some criteria (e.g., beam IDs that overlap with the given beam for some beam width metric (e.g., half-power beam width)). A reference point (or origin) of a coordinate system and (x, y) direction may be specified. For example, Fig. 9A and Fig. 9B As shown, the reference point can be set to the center of the 2D area. In one embodiment, the absolute (x, y) direction is used to indicate the estimated future beam direction. For example, the x direction and the y direction can be set to the west and the north, respectively. In another embodiment, the relative (x, y) direction is used. For example, the x direction and the y direction relative to the vehicle heading are used to indicate the future beam direction. In some embodiments, instead of 2D polar coordinates, a 3D polar coordinate system is used to include vertical beam information, which is useful for 3D beamforming (e.g., horizontal and vertical beamforming). In some embodiments, 2D (or 3D) azimuth beam information can be indexed by a future time instance or time window after which the shared beam information is valid. In some embodiments, when multiple beams are transmitted simultaneously in different directions, an overlap of azimuth beam information associated with each of these beams can be sent. Otherwise, the information can identify each beam in the form of a bitmap. In this way, future beam information (beam direction and beam width) is indicated with low overhead.

[0034] The methods described in the present disclosure may be applied to any sidelink communication, for example, Long-Term Evolution (LTE) or 5G New Radio (NR) or future generation (sixth generation (6G), seventh generation (7G) or any future generation) sidelink communication.
