This document is directed generally to wireless communications, and in particular to 5G communications.
With the development of wireless multimedia services, demands for high data rate and great user experience continuously increase, resulting in higher requirements of the system compacity and coverage of conventional cellular networks. On the other hand, demands for proximity services also increase because of application scenarios such as public security, social network, near-field data sharing and local advertisement. Traditionally, the cellular network using the base station as the center may have obvious limitations on supporting the high data rates and the proximity service. In order to satisfy such requirements, device-to-device (D2D) communication technology is proposed. By applying the D2D communication technology, the burden of the cellular network can be relieved, power consumption of the user equipment (UE) can be reduced and the data rate can be increased and the robustness of the network infrastructure can be improved. Thus, the demands for high data rate and proximity services are greatly satisfied. In this context, D2D communication technology is also named proximity services (ProSe) or sidelink communications, wherein an interface between the UEs is called sidelink interface.
The UE using the sidelink communications support two resource modes, i.e., mode1 and mode2. For the mode1, the UE uses resources scheduled by the network to transmit sidelink data. For the mode2, the UE selects transmission resources by itself to transmit the sidelink data.
In addition, the wireless communications are performed on carriers or frequency bands. Two different frequency ranges are available for the 5G technology including sidelink and the different ranges have been designated FR1 (frequency range 1) and FR2 (frequency range 2). The bands in the FR1 are envisaged to carry much of the traditional cellular mobile communications traffic. The higher frequency bands in the FR2 are aimed at providing short range very high data rate capability for the 5G radio. With 5G wireless technology anticipated to carry much higher speed data, the additional bandwidth of these higher frequency bands will be needed. Originally, the FR1 band was intended to define bands below 6 GHZ, but with anticipated additional spectrum allocations, the FR1 range was extended to 7.125 GHz after the WRC19 (World Radio Conference in 2019) where global spectrum allocations were agreed. Currently, the UE may be able to communicate directly with each other (i.e., without use of a base station) on the carrier within the FR1. To improve the data rate, sidelink communications may be applied on the carrier within the FR2.
When low-range and mid-range of frequency are used, a signal can be transmitted in all direction or relatively wide angles. However, when the very high frequency (e.g., the carrier in the FR2) is used, a huge antenna array may be necessary. As a result of using such huge antenna array, the resulting radiation would be a beam. The corresponding technology is called beamforming. For a device, each beam occupies a specific direction. By adopting different transmission parameter, wireless device can control the direction of the beam. However, when communicate with other device, questions of which beam should be used, whether the used beam still works well and how to select a resource for transmitting data by using the beam need to be addressed.
This document relates to methods, systems, and devices for the D2D communications, and in particular to methods, systems, and devices for the D2D communications using a carrier in a frequency range (e.g., the FR2).

In an embodiment, the TX UE (e.g., the first user device in
In an embodiment, the beam measurement configuration may include a beam RS configuration.
In an embodiment, the beam measurement configuration may include a sorting quantity.
In an embodiment, the beam measurement configuration may include a reporting quantity.
For example, the sorting or reporting quantity may be/comprise at least one of: a Reference Signal Receiving Power (RSRP), a Reference Signal Receiving Quality (RSRQ), Received Signal Strength Indicator (RSSI), Signal to Interference plus Noise Ratio (SINR), a preferred level, a recommendation level, a channel busy ratio, or non-preferred level.
In an embodiment, the RX UE sends beam measurement result(s) to the TX UE.
The beam measurement result can be at least one of: RSRP, RSRQ, RSSI, or SINR
In an embodiment, the beam is represented by the beam ID.
In an embodiment, the beam measurement result(s) includes at least one beam ID (identifier), where the beam ID may be an ID of a beam RS (reference signal), a beam index, an index of the beam RS.
In an embodiment, the RX UE includes the beam ID in an order of decreasing sorting quantity. For example, if the sorting quantity is preferred level and N beam IDs are included in the beam measurement result, the first (1st) beam ID in the beam measurement result is the most preferred beam to be used for communication from RX UE's perspective. The last beam ID in beam measurement result is the least preferred beam to be used for communication.
In an embodiment, if the sorting quantity is non-preferred level and N beam IDs are included in the beam measurement result, the first beam ID in the beam measurement result is the most non-preferred beam to be used for communication from the perspective of the RX UE. That is the last beam ID in the beam measurement result is the least non-preferred beam to be used for the communications.
In an embodiment, the RX UE includes the beam ID in order of increasing sorting quantity. For example, if the sorting quantity is the preferred level and N beam IDs are included in the beam measurement result. The last beam ID in the beam measurement result is the most recommended beam to be used for communication from RX UE's perspective. The first beam ID in the beam measurement result is the least recommended beam to be used for communication.
In an embodiment, the beam measurement configuration may further include a measurement result report threshold. In this embodiment, the RX UE includes a beam ID in the beam measurement result if the beam measurement result of the bead corresponding to the beam ID is above the measurement result report threshold.
In an embodiment, the beam measurement result can be at least one of: RSRP, RSRQ, or SINR.
In an embodiment, the network configures the beam measurement configuration to the TX UE for the RX UE to report the beam measurement result.
In an embodiment, when detecting beam failure, the UE may trigger a beam failure recovery. In response to the beam failure recovery being triggered, the UE sends a beam failure recover signaling to the peer UE. The beam failure recovery signaling may include the beam measurement result.
In one embodiment, due to change of channel quality, the selected beam may be not appropriate to be used for the communications. Under such conditions, the UE (e.g., TX UE or first user device shown in
In one embodiment, the UE may need to select an appropriate beam from a candidate beam list for a specific destination (e.g., another UE or peer UE or second user device in
In one embodiment, when the UE performs the beam (re-)selection, the UE determines that all the beams are included in the candidate beam list.
In one embodiment, the peer UE may only report, to the UE, the beam(s) with measurement result(s) higher than a measurement result report threshold. In this embodiment, the UE determines the beam(s) reported by the peer UE as candidate beam.
In one embodiment, when/if the UE performs the beam (re-)selection, the UE excludes the non-preferred beam received from the peer UE from the candidate beam list.
In one embodiment, when/if the UE performs the beam (re-)selection, the UE selects a beam from a preferred beam list received from the peer UE.
In one embodiment, when/if the UE performs the beam (re-)selection, the UE selects a beam from a recommended beam list received from the peer UE.
In one embodiment, when/if the UE performs the beam (re-)selection, the UE determines the beam with the measurement result above a beam selection threshold as a candidate beam. The beam selection threshold may be received from the network. As an alternative or in addition, the beam selection threshold may be received from the peer UE.
In one embodiment, if/when UE performs the beam (re-)selection, the UE selects the beam within an intersection of the candidate beam list and the preferred beam list received from peer UE. That is the selected beam is in both the candidate beam list and the preferred beam list.
In an embodiment, for the beam (re)selection, the TX UE performs at least one of following:
In an embodiment, the beam selection threshold is configured by the network.
In an embodiment, the TX UE may trigger a beam re-selection or beam switching if at least one of the following conditions is met:
In one embodiment, the beam re-selection threshold is configured by the network.
In an embodiment, if the UE determines that beam re-selection is triggered, the UE triggers resource re-reselection.
In an embodiment, if the UE determines that beam switching is triggered, the UE triggers resource re-reselection.
In one embodiment, after receiving the resource assistance information from the peer UE (e.g., RX UE or second user device shown in
If the condition is met, the UE take the assistance information into consideration during resource selection. For example, the UE selects the resource within the intersection of preferred resource set and its own sensing result.
In one embodiment, if/when the UE performs beam (re-)selection, the UE selects the beam within the intersection of the candidate beam list and the recommended beam list received from the peer UE.
The resource assistance information may include a set of resource, e.g., preferred resource, non-preferred resource. The resource assistance information may be generated by using beam forming, i.e., the RX UE may provide the resource assistance information in granularity of beam. Therefore, the resource assistance information include the beam ID. The Beam ID can be ID of beam RS. The Beam ID can be index of beam RS.
In one embodiment, it is possible that the transmission resource is associated to the beam direction, i.e., different beam may have different candidate resource set. For example, the UE has two beams with different beam directions BD1 and BD2. Based on the result of monitoring result on the different beam directions BD1 and BD2: On beam direction BD1, slots 1, 2 and 3 are available and considered as a candidate resource set associated with the beam direction BD1. On the beam direction BD2, slots 3,4 and 5 are available and considered as a candidate resource set associated to the beam direction BD2.
In one embodiment, if/when the UE needs to select a transmission resource, the UE selects a beam from a candidate beam and selects the resource from the candidate resource associated to the selected beam.
In one embodiment, the UE may not select a beam during resource selection. The UE can determine which beam to be used when MAC PDU is generated. Therefore, the resources associated to the candidate beam can be selected. As an alternative or in addition, when the UE needs to select a transmission resource, the UE selects the resource from the candidate resources associated to the candidate beam. As an alternative or in addition, when the UE needs to select a transmission resource, the UE selects the resource from the candidate resource associated with any candidate beam of a destination (e.g., RX UE) having a logical channel with the highest priority.
In one embodiment, the UE determines the selected transmission resource is a sidelink grant or selected grant or selected sidelink grant.
In one embodiment, after selecting the transmission resource, the UE needs to allocate the transmission resource. In response to the UE needing to select a destination for resource allocation, the UE selects the destination (e.g., if the beam of the sidelink grant is one candidate beam of the destination.
The beam of the sidelink grant is the beam of the transmission resource selected from the resource set of the beam. For example, the transmission resource 1 is selected from the resource set(1, 2, 3) of beam 1, and the transmission resource-1 is considered as a selected sidelink grant, then the beam 1 is the beam of the sidelink grant.
In one embodiment, in response to the UE needing to select a destination for resource allocation, the UE selects the destination if the measurement result received from the destination UE of beam of the sidelink grant is higher than the beam selection threshold. For example, UE select the transmission resource-1 from resource set of beam-1, and considers the selected transmission resource as grant. Then the beam of sidelink grant is on the beam direction BD1. For a destination-1, the measurement result of the beam on the beam direction BD1 is 53 which is higher than the beam selection threshold=38. The destination-1 can be selected. For the destination-2, the measurement result of the beam on the beam direction BD2 on is 20 which is smaller than the beam selection threshold=38. Thus, the destination-2 should not be selected.
In one embodiment, the peer destination UE may only report the beam with the measurement result higher than the measurement result report threshold. If the UE needs to select a destination (UE) for the resource allocation, the UE selects the destination (UE) if the beam of the sidelink grant is within the beam list reported by the destination (UE). For example, the transmission resource (1) is selected from the resource set(1, 2, 3) of a beam-1 and considered as the selected sidelink grant. The destination UE-1 measures the beam-1 and determines not to include the beam-1 in the measurement report since the measurement result of the beam-1 is lower than the measurement result report threshold. In other words, the beam measurement report may only include (beam 2, 3, 4). During the destination selection for the destination UE-1, since the selected beam-1 is not within the beam list (2, 3, 4) reported by the destination UE-1, the destination UE-1 should not be selected. For a destination UE-2, the beam list (1, 2, 3) is reported. During destination selection, since the selected beam-1 is within the beam list (1, 2, 3) reported by the destination UE-2, the destination UE-2 can be selected.
In one embodiment, the UE may have a power saving requirement. To save the power, the UE may performs Discontinuous Reception (DRX). Specifically, the UE only monitors the channel for reception in an active time of the DRX, wherein the active time is a time duration. The active time includes at least one of following:
In an embodiment, the UE considers it is in an active time of the Sidelink relay DRX if a discovery message is transmitted and a response message is received.
In an embodiment, the UE considers it is in the active time of the Sidelink relay DRX if a beam failure is detected. In this embodiment, the UE considers it is not in the active time of the Sidelink relay DRX after the beam failure is recovered.
In an embodiment, the UE detects a failure on an indirect path to a destination (e.g., second wireless communication device) and cannot transmit SRB1 to the destination, the UE applies a default SRB configuration on a Uu path with the destination and performs the transmission via the Uu interface/path.
In an embodiment, the indirect path refers to a path on which the first wireless communication device communicates with the second wireless communication device via the third wireless communication device (e.g., relay (terminal).
In an embodiment, the dedicated configuration is for a standalone signal.
In an embodiment, the standalone signaling comprises at least one of a beam RS, sidelink control information, or a request of the beam RS measurement.
In an embodiment, the beam RS may be CSI (channel state information) RS, an SRS (sounding reference signal) or a sidelink SSB (synchronization signal/physical broadcast channel block).
In an embodiment, the first user device (e.g., TX UE) sends at least one of the following standalone signaling transmission information to the second user device (e.g., network) and receive a sidelink grant (e.g., dedicated configuration) for the standalone signaling from the second user device network:
In an embodiment, standalone signaling transmission information is included in at least one of: an RRC signaling, a MAC CE (media access control control element), or a buffer status report MAC CE,
In an embodiment, the second user device sends at least one of the following configurations of standalone signaling to the first user device and the first user device sends the standalone signaling (e.g., to another user device):
In an embodiment, if the first user device does not has resources for transmitting the standalone signaling, the first user device triggers a scheduling request.
In an embodiment, the storage unit 510 and the program code 512 may be omitted and the processor 500 may include a storage unit with stored program code.
The processor 500 may implement any one of the steps in exemplified embodiments on the wireless terminal 50, e.g., by executing the program code 512.
The communication unit 520 may be a transceiver. The communication unit 520 may as an alternative or in addition be combining a transmitting unit and a receiving unit configured to transmit and to receive, respectively, signals to and from a wireless network node (e.g., a base station).
In an embodiment, the storage unit 610 and the program code 612 may be omitted. The processor 600 may include a storage unit with stored program code.
The processor 600 may implement any steps described in exemplified embodiments on the wireless network node 60, e.g., via executing the program code 612.
The communication unit 620 may be a transceiver. The communication unit 620 may as an alternative or in addition be combining a transmitting unit and a receiving unit configured to transmit and to receive, respectively, signals to and from a wireless terminal (e.g., a user equipment or another wireless network node).
In
When/If the UE has not connected to the network (e.g., the UE is in an RRC IDLE or RRC INACTIVE state), the UE can connect with the network via either the direct path or the indirect path. After connecting to network, the network can add another path to the UE. For example, the UE may initiate the connection with the network via the direct path and the network may add the indirect path to (communicate with) the UE. As an alternative, the UE initiates the connection with network via the indirect path, and the network adds the direct path to the UE.
For each radio bearer (RB) of the UE, each RB can be configured on the direct path or the indirect path or both (i.e., multiple paths) the direct and indirect paths. In other words, the RB type can be direct path RB, indirect path RB, or multiple path RB. For the direct path RB, the RB is configured with a Uu RLC (radio link control) configuration. For the indirect path RB, the RB is configured with a sidelink RLC configuration. For multiple path bearer, the RB is configured with both the Uu RLC configuration and the sidelink RLC configuration.
Upon/after the connection of one path is failure due to at least one of radio link failure, beam failure, or listen before talk failure, the UE can report the failure information via another path. For example, if the direct path is failed, the UE reports the failure information via the indirect path. If the indirect path is failed, the UE reports the failure information via the direct path.
In one embodiment, the failure information can only be transmitted via a specific RB, e.g., SRB1 (Signalling Radio Bearer 1).
If the specific RB is the indirect path bearer and if the indirect path is failed, the UE changes the RB type of this RB from the indirect path bearer to the direct path bearer, applies the default sidelink RLC configuration for this specific RB and transmits the failure information to network.
If the specific RB is the direct path bearer and if the direct path is failed, the UE changes the RB type of this RB from the direct path bearer to the indirect path bearer, applies the default Uu RLC configuration for this specific RB and transmits the failure information to the network.
In one embodiment, when the UE (e.g., remote UE) connects to the network via the indirect path (i.e., via relay UE), the relay UE needs to be configured with an RLC configuration. The RLC configuration is used for relay UE to forward the packet of the remote UE. To allow the relay UE to differentiate the received RLC bearer belongs to the remote UE or the relay UE, the RLC configuration includes an first indication. After receiving the RLC configuration with the remote UE indication, the relay UE determines that this RLC configuration is used for forwarding the traffic/data of the remote UE. In one embodiment, the UE receives at least one of following first indication from network: remote UE indication, remote UE ID, indirect path indication, relay UE indication, relay UE ID, direct path indication, UE aggregation indication. In one embodiment, the first indication is included in the RLC configuration.
In one embodiment, the UE receives the Channel Occupancy Time (COT) sharing information including shared COT from peer UE. The COT is a consecutive or non-consecutive time duration occupied by performing listen before talk. It is possible that the selected transmission resource is not within the shared COT. To utilize the COT sharing information as much as possible, if the selected transmission resource is not within the shared COT, the UE may trigger a resource re-selection. For example, if all selected transmission resources is not within the shared COT, or there is candidate resource which is not selected and this candidate resource is within the shared COT, the UE may trigger the resource re-selection. The selected transmission resource is considered as a selected grant.
In one embodiment, if no selected transmission resource is within the shared COT, the UE triggers the resource re-selection.
In one embodiment, if there are no resources within the intersection of the sensing results of the UE and the COT shared by peer UE, the UE selects the transmission resource from its own sensing results.
In one embodiment, if there are no resources within the intersection of the sensing results of the UE and the COT obtained by the UE, the UE selects the transmission resource from the sensing results.
In one embodiment, if the candidate resource is available and is within the shared COT, UE shall trigger resource re-selection.
In one embodiment, if any selected transmission resources is not within the shared COT, UE shall trigger resource re-selection.
In an embodiment, the sensing results comprise a set of candidate resource set determined by the UE.
In one embodiment, except the COT sharing, the UE obtains a COT by performing a type1 listen before talk. If the selected transmission resource is not within the obtained COT, the UE triggers the resource re-selection. As an alternative, if all selected transmission resources are not within the obtained COT, the UE triggers the resource re-selection. As an alternative, if all selected transmission resources are not within the obtained COT, the UE shall trigger resource re-selection. As an alternative, if no selected transmission resource is within the obtained COT, the UE shall trigger resource re-selection. Optionally, if the candidate resource is available and is within the obtained COT, the UE shall trigger resource re-selection. Optionally, if any selected transmission resource is not within the obtained COT, the UE shall trigger resource re-selection.
In one embodiment, if negative-only acknowledgement was enabled and no negative acknowledgement was received for the transmission of MAC PDU, the UE considers the remaining transmission resources of this MAC PDU as transmission resource of another MAC PDU.

By way of example, and not limitation, such computer-readable media can include RAM, ROM, EEPROM, CD-ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other medium that can be used to store desired program code in the form of instructions or data structures and that can be accessed by a computer.
In this document, the term “unit” as used herein, refers to software, firmware, hardware, and any combination of these elements for performing the associated functions described herein. Additionally, for purpose of discussion, the various units are described as discrete units; however, as would be apparent to one of ordinary skill in the art, two or more units may be combined to form a single unit that performs the associated functions according embodiments of the present disclosure.
Additionally, memory or other storage, as well as communication components, may be employed in embodiments of the present disclosure. It will be appreciated that, for clarity purposes, the above description has described embodiments of the present disclosure with reference to different functional units and processors. However, it will be apparent that any suitable distribution of functionality between different functional units, processing logic elements or domains may be used without detracting from the present disclosure. For example, functionality illustrated to be performed by separate processing logic elements, or controllers, may be performed by the same processing logic element, or controller. Hence, references to specific functional units are only references to a suitable means for providing the described functionality, rather than indicative of a strict logical or physical structure or organization.
Various modifications to the implementations described in this disclosure will be readily apparent to those skilled in the art, and the general principles defined herein can be applied to other implementations without departing from the scope of the claims. Thus, the disclosure is not intended to be limited to the implementations shown herein, but is to be accorded the widest scope consistent with the novel features and principles disclosed herein, as recited in the claims below.
This application is a continuation of International Patent Application No. PCT/CN2023/076649, filed on Feb. 17, 2023, the disclosure of which is incorporated herein by reference in its entirety.
