Description

Methods, devices, and media for sidelink sensing resource allocation under base station control TECHNICAL FIELD

[0001] The present disclosure relates generally to communication technologies, and more particularly, to sidelink (SL) sensing resource allocation under base station control. BACKGROUND

[0002] User Equipment (UE) supporting sidelink communication can employ sidelink resource allocation under base station control (also referred to as resource allocation Mode 1), which is divided into dynamic resource allocation (referred to as Dynamic Grant (DG)), static resource allocation (referred to as Configured Grant Type 1 (CG Type 1)), and semi-static resource allocation (referred to as Configured Grant Type 2 (CG Type 2)).

[0003] The three allocation modes are shown in (A) to (C) in FIG. 1. In (A) of FIG. 1, dynamic resource allocation DG is shown. In this mode, a Tx UE that needs to transmit data sends a scheduling request (SR) to a base station gNB. The base station responds to the SR by sending downlink control information (DCI) for scheduling resources. The DCI is used to schedule resources that support data transmission. The Tx UE performs data transmission with a Rx UE via sidelink control information (SCI) and a physical sidelink shared channel (PSSCH) using the allocated resources.

[0004] Static resource allocation CG Type 1 is shown in (B) of FIG. 1. In this mode, the base station configures periodic resources for the UE through radio resource control (RRC) signaling. The RRC configuration parameters can include a configuration index, a time offset, a time-frequency allocation, a periodicity for the UE to transmit data, etc. The Tx UE transmits packets using the periodic resources configured by the base station through RRC without having to request resources before each data transmission.

[0005] Semi-persistent resource allocation CG Type 2 is shown in (C) of FIG. 1. In this mode, the base station configures periodic resources for the UE through Radio Resource Control (RRC) signaling. The RRC configuration parameters can include the periodicity at which the UE transmits data. Unlike CG Type 1, in CG Type 2, the base station needs to send a specific DCI activation signal after sending the RRC signaling, which is used to configure, for example, configuration index, time-frequency allocation, etc. The UE, after receiving the DCI activation signal, can transmit data according to the parameters configured through RRC signaling and DCI.

[0041] The features and aspects of the present disclosure will become apparent from reading the following detailed description, with reference to the attached drawings. DETAILED DESCRIPTION

[0042] In the following, various exemplary embodiments of the present disclosure will be described in detail with reference to the attached drawings. In this specification, all implementations of the embodiments are not described in order to be clear and brief. However, it should be noted that many implementation-specific settings can be made in order to achieve specific goals of developers in implementing the embodiments of the present disclosure, according to specific needs. In addition, it should also be appreciated that although development work can be relatively complex and time-consuming, it is only a routine task for those skilled in the art who benefit from the present disclosure.

[0043] In addition, it should be noted that, in order not to obscure the disclosure due to unnecessary details, only the processing steps and / or device structures closely related to the technical solutions of the disclosure are shown in the drawings. The following description of the exemplary embodiments is merely illustrative and is not intended to be any limitation on the disclosure and its applications.

[0044] In the 3GPP RANP#102 meeting, it is proposed to study the integration of sensing in Rel-19. In the scenario of sensing integration, the sending end of the sensing signal can be a transmission and reception point (TRP) / user equipment (UE), the receiving end of the sensing signal can be a TRP / UE, and the sensing target can be an object without connection capability / with connection capability. The sensing receiving end analyzes the shape, position and speed of the sensing target by receiving the radio waves reflected by the sensing target, and tracks the sensing target.

[0045] Unlike the one-to-many mode of base station and user, the sensing between UEs under sidelink communication is often a many-to-many scenario. If multiple sidelinks share the same sensing resource pool, resource collision behavior is easy to occur. The sensing between UEs under the control of the base station is the preferred solution.

[0046] The embodiments of the disclosure consider improving the existing sidelink resource allocation mode under the control of the base station for sidelink data transmission in the case of using UEs to implement sensing. The embodiments of the disclosure consider indicating in the resource allocation information whether the allocated resource is a resource allocated for the UE to perform sensing with another UE through a sidelink. The embodiments of the disclosure design a new DCI format (for example, a new DCI format 3_x) and / or RRC configuration signaling (more specifically, a new information element for configuring sensing resources) to indicate whether the allocated resource is a resource allocated for the UE to perform sensing with another UE through a sidelink. In the case where the UE needs to perform sensing, the sensing signal is transmitted using the allocated sensing resource, and feedback about the sensing signal is received via the sidelink between the UE and another UE capable of receiving the sensing signal or the reflected sensing signal.

[0047] Sensing service and data service share resource pool

[0048] When the sensing service is introduced in the sidelink communication, the sensing service can share the resource pool with the data service.

[0049] Dynamic resource scheduling

[0050] In the case that the Tx UE actively performs sensing, the resource allocation manner for sensing service can directly reuse the existing resource allocation manner for data transmission. Specifically, the Tx UE can request SL resources from the base station (e.g., gNB) by sending an SR to the base station, for example, and the base station allocates non-conflicting SL resources for it, which can be decided by the SL UE itself whether to be used to provide sensing service or to perform data transmission. In other words, the interaction process between the SL UE and the base station is similar to the interaction process between the Tx UE and the gNB shown in (A) of FIG. 1.

[0051] FIG. 2 shows an example scenario in which the base station needs SL UE assistance for sensing according to an embodiment of the present disclosure. As shown in FIG. 2, for sensing target 1, the base station can directly send a sensing signal to it, which is reflected to UE 2, and sensing feedback is performed by UE 2 through uplink (UL). For sensing target 2, the base station wants to sense the position of target 2, but UE1 blocks in front of target 2, so the sensing signal of the base station cannot sense the existence of target 2, and therefore the base station needs UE1 to perform sensing through SL to assist the base station in confirming target 2 in the coverage. In this case, the base station needs to actively allocate SL resources for UE1 for sensing, and therefore the resource allocation process needs to be changed to the existing standard.

[0052] FIG. 3 shows a flowchart of a base station triggered dynamic resource scheduling method 300 according to some embodiments of the present disclosure.

[0053] Unlike the existing dynamic resource scheduling, in the example of FIG. 2, the resource allocation of the SL link is not because UE1 (Tx UE) has SL data to transmit, but because the base station side has sensing needs, and therefore there is no step of UE1 (Tx UE) sending an SR to request SL resources in the resource request process. In the DCI issued by the base station, it needs to be explicitly indicated that the allocated resources are for sensing purposes. In this case, a new DCI format can be added to indicate whether the allocated resources are resources allocated for a user device UE to perform sensing with another UE through a sidelink.

[0054] The new DCI format includes DCI format 3_x. The DCI format 3_x can be scrambled with a sensing related scrambling sequence to distinguish it from other DCI formats. In other words, a scrambling sequence specific to sensing can be configured, and when the DCI format 3_x is scrambled with the scrambling sequence specific to sensing, it indicates that the allocated resources are for sidelink sensing service.

[0055] A field can also be added in DCI format 3_x to indicate that the DCI format is control information for scheduling sensing resources. Different values of the added field in DCI format 3_x can be used to indicate whether the allocated resources are for sidelink data transmission or sidelink sensing service. Whether the allocated resources are for sidelink data transmission or sidelink sensing service can also be indicated by whether the DCI format 3_x contains the added field.

[0056] As shown in FIG. 3, when the base station needs Tx UE to assist in sensing, the base station sends a new DCI format, such as DCI format 3_x as described above, to the Tx UE. The Tx UE transmits a sensing signal using the sensing resources scheduled by the DCI format and receives feedback from the Rx UE about the sensing signal. The Rx UE can be any sidelink communication enabled UE that receives the sensing signal or the reflected sensing signal.

[0057] FIG. 2 only shows one example scenario in which the base station needs SL UE to assist in sensing. In some cases, the sensing target can be in a relatively remote area, and when the base station directly transmits a sensing signal to the sensing target, the sensing signal cannot reach the sensing target, or when the sensing signal reaches the sensing target, the quality of the sensing signal is not good enough. In this case, the base station can first transmit data to a nearby Tx UE, and then the Tx UE can sense the sensing target. Those skilled in the art can think of various example scenarios in which the base station needs SL UE to assist in sensing.

[0058] • Static resource configuration & semi-static resource configuration

[0059] In the case of static resource configuration or semi-static resource configuration, the interaction between the Tx UE and the base station is similar to the flow shown in (B) or (C) in FIG. 1.

[0060] FIG. 4 shows a flowchart of a static resource configuration method 400 according to an embodiment of the present disclosure.

[0061] As shown in FIG. 4, the base station (e.g., gNB) can configure periodic resources for the Tx UE (e.g., UE1 in FIG. 2 or any UE that needs to transmit a sensing signal) through RRC signaling, and in the resource configuration, it is clear which configuration is for sensing service resources and which configuration is for data service resources. In the case of needing to perform sensing, the Tx UE transmits a sensing signal using the periodic resources configured by the base station for sensing, and receives feedback about the sensing signal sent from the Rx UE.

[0062] FIG. 5 shows a flowchart of a semi-static resource configuration method 500 according to an embodiment of the present disclosure.

[0063] As shown in FIG. 5, the base station (e.g., gNB) can configure periodic resources to the Tx UE through RRC signaling. In this case, a new DCI format is added to activate the configured resources, for example, DCI format 3_x as described above, to indicate whether the activated periodic resources are sensing service resources or data service resources. In the case of performing sensing, the Tx UE transmits sensing signals using the resources configured for sensing by the activation DCI and receives feedback on the sensing signals transmitted from the Rx UE after receiving the DCI activating the periodic resources.

[0064] When the base station configures periodic resources through RRC signaling in the static resource configuration or semi-static resource configuration mode, an information element (IE) for configuring sensing resources is added.

[0065] The following shows an exemplary IE "SL-ScheduledConfig" for configuring sensing resources. The IE "SL-ScheduledConfig" specifies the sidelink communication / positioning / sensing configuration for network-scheduled NR sidelink communication / positioning / sensing.

[0066] Wherein, sl-PeriodCG-rXX indicates the period of the configured grant resources, sl-TimeOffsetCG-Type1-rXX indicates the time domain offset configured relative to the logical slot, sl-TimeReferenceSFN-Type1-rXX indicates the logical slot determined that can be used to transmit SL data, sl-ResourcePoolID-rXX indicates the resource pool ID of the configured periodic grant resources, and sl-TimeResourceCG-Type1-rXX indicates the time domain location of SL CG Type1.

[0067] Those skilled in the art can understand that the above is only an example of an information element (IE) for configuring sensing resources. Those skilled in the art can make different designs according to actual needs.

[0068] Sensing service and data service do not share resource pools

[0069] If the sensing service and the data service both have specific resource pools, the three resource allocation modes shown in FIG. 1 also need to be modified accordingly.

[0070] • Dynamic resource scheduling

[0071] FIG. 6 shows a flow chart of a dynamic resource configuration method 600 according to an embodiment of the present disclosure.

[0072] As shown in FIG. 6, the flow chart is of a UE-triggered dynamic resource configuration method. The Tx UE sends an SR to the base station to request scheduling resources. Unlike (A) of FIG. 1, when the Tx UE needs to acquire information of surrounding sensing targets through sensing, the Tx UE also sends a Buffer Status Report (BSR) to the base station to request resources for transmitting sensing signals from the base station. The Tx UE can help the base station to allocate resources by distinguishing in the BSR whether the current request is for sensing resources or data resources.

[0073] FIG. 7 shows a structure of an exemplary BSR MAC CE according to an embodiment of the present disclosure. As shown in FIG. 7, the BSR MAC CE can include three fields, in addition to the LGC ID indicating the logical channel ID, the buffer size indicating the buffer capacity, and a service field indicating the service class. The service field can inform the base station whether the resources requested this time are requested for data transmission service or for sensing service.

[0074] The BSR can not include a destination ID, because the transmission of the sensing signal does not limit the destination UE. In other words, the Tx UE does not send the sensing signal to a specific Rx UE. The Tx UE receives feedback about the sensing signal from the Rx UE that can receive the sensing signal or the reflected sensing signal.

[0075] In response to the BSR, the base station can schedule resources for sensing service for the Tx UE via a new DCI format, such as the above-mentioned DCI format 3_x. When indicating the scheduled resources by DCI, it is necessary to distinguish whether the current scheduling is for data transmission resources or sensing service resources. In the case where the Tx UE needs to perform sensing, the Tx UE can send the sensing signal according to the configured sensing resources. The Rx UE that receives the sensing signal or the reflected sensing signal sends feedback about the sensing signal to the Tx UE.

[0076] • Static resource configuration & semi-static resource configuration

[0077] The base station configures periodic resources to the Tx UE through RRC signaling, and in the resource configuration, it is clear which configuration is the resource of the sensing service and which configuration is the resource of the data service. If it is a semi-static resource indication mode, it also needs to indicate in the DCI that activates the configuration resource whether the activated periodic resource this time is the resource of the sensing service or the resource of the data service. The DCI is, for example, the DCI format 3_x as described above. The modification of the specific signaling is basically similar to the signaling modification in the case of multiplexing the sensing service and the data service in the same resource pool. The specific process is similar to the method processes shown in FIG. 4 and FIG. 5.

[0078] FIG. 8 shows a flowchart of a method 800 of sidelink resource allocation according to embodiments of the present disclosure. The method 800 can be performed by a UE (e.g., a Tx UE) or a processor of the UE.

[0079] As shown in FIG. 8, the method 800 can include operation 801 of receiving, from a base station, resource allocation information including information indicating whether allocated resources are resources allocated for a user device, UE, to perform sensing with another UE over a sidelink.

[0080] The method 800 can further include operation 803 of transmitting, based on the resource allocation information including the information indicating that the allocated resources are resources allocated for the UE to perform sensing with another UE over the sidelink, a sensing signal using the allocated resources.

[0081] The method 800 can further include operation 805 of receiving, from another UE (e.g., a Rx UE in FIGS. 3-6) that receives the sensing signal or the reflected sensing signal, feedback about the sensing signal.

[0082] FIG. 9 shows a flowchart of a method 900 of sidelink resource allocation according to embodiments of the present disclosure. The method 900 can be performed by a TRP or a base station, or a processor of the TRP or the base station.

[0083] As shown in FIG. 9, the method 900 can include operation 901 of transmitting, to a user device, UE, resource allocation information including information indicating whether allocated resources are resources allocated for the UE to perform sensing with another UE over a sidelink.

[0084] In some embodiments, the resource allocation information includes a new DCI format, for example, the DCI format 3_x as described above. The new DCI format can indicate whether the allocated resources are resources allocated for the UE to perform sensing with another UE over the sidelink.

[0085] In some embodiments, the resource allocation information can also include an information element included in the RRC configuration for configuring the sensing resource to explicitly indicate which configuration is for the resource of the sensing service and which configuration is for the resource of the data service.

The gNB can be a gNB of a small cell covered by a macro cell, such as a pico gNB, a micro gNB, and a home (femto) gNB. Alternatively, the base station can be implemented as any other type of base station, such as a NodeB, an eNodeB, and a base transceiver station (BTS) or a network-side infrastructure in a next-generation communication standard.

[0094] Hereinafter, an example of a base station and user equipment to which the technology of the present disclosure can be applied will be briefly introduced.

[0095] It should be understood that the term "base station" used in the present disclosure has all the breadth of its ordinary meaning and at least includes a wireless communication station used as a part of a wireless communication system or a radio system to facilitate communication. In a D2D, M2M, and V2V communication scenario, a logical entity having a control function for communication can also be referred to as a base station. In a cognitive radio communication scenario, a logical entity playing a role of spectrum coordination can also be referred to as a base station. In an automated factory, a logical entity providing a network control function can be referred to as a base station.

[0096] First application example of base station

[0097] FIG. 10 is a block diagram illustrating a first example of a schematic configuration of a base station to which the technology of the present disclosure can be applied. In FIG. 10, the base station can be implemented as a gNB 1400. The gNB 1400 includes a plurality of antennas 1410 and a base station apparatus 1420. The base station apparatus 1420 and each of the antennas 1410 can be connected to each other via an RF cable.

[0098] The antennas 1410 include a plurality of antenna elements, such as a plurality of antenna arrays for massive MIMO. The antennas 1410, for example, can be arranged in a matrix of antenna arrays and used for the base station device 1420 to transmit and receive wireless signals. The plurality of antennas 1410, for example, can be compatible with a plurality of frequency bands used by the gNB 1400.

[0099] The base station device 1420 includes a controller 1421, a memory 1422, a network interface 1423, and a wireless communication interface 1425.

[0100] The controller 1421 can be, for example, a CPU or a DSP, and operates various functions of a higher layer of the base station device 1420. For example, the controller 1421 generates data packets from data in a signal processed by the wireless communication interface 1425, and delivers the generated packets via the network interface 1423. The controller 1421 can bundle data from a plurality of baseband processors to generate bundled packets, and deliver the generated bundled packets. The controller 1421 can have a logical function that performs control such as radio resource control, radio bearer control, mobility management, admission control, and scheduling. The control can be performed in conjunction with a nearby gNB or a core network node. The memory 1422 includes RAM and ROM, and stores programs executed by the controller 1421 and various types of control data such as a terminal list, transmission power data, and scheduling data.

[0101] The network interface 1423 is a communication interface used to connect the base station device 1420 to a core network 1424 (e.g., a 5G core network). The controller 1421 can communicate with a core network node or another gNB via the network interface 1423. In this case, the gNB 1400 and the core network node or other gNBs can be connected to each other by logical interfaces such as an NG interface and an Xn interface. The network interface 1423 can also be a wired communication interface or a wireless communication interface for a wireless backhaul line. If the network interface 1423 is a wireless communication interface, the network interface 1423 can use a higher frequency band for wireless communication than a frequency band used by the wireless communication interface 1425.

[0102] The wireless communication interface 1425 supports any cellular communication scheme such as 5G NR and provides wireless connectivity to terminals located in the cell of the gNB 1400 via the antennas 1410. The wireless communication interface 1425 can generally include, for example, a baseband (BB) processor 1426 and an RF circuit 1427. The BB processor 1426 can perform, for example, encoding / decoding, modulation / demodulation, and multiplexing / demultiplexing, and perform various types of signal processing of layers (e.g., physical, MAC, RLC, PDCP, SDAP layers). The BB processor 1426 can have a part or all of the logical functions described above instead of the controller 1421. The BB processor 1426 can be a memory that stores a communication control program, or a module including a processor and related circuitry configured to execute the program. Updating the program can cause the functions of the BB processor 1426 to change. The module can be a card or a blade that is inserted into a slot of the base station device 1420. Alternatively, the module can also be a chip mounted on a card or a blade. Meanwhile, the RF circuit 1427 can include, for example, a mixer, a filter, and an amplifier, and transmit and receive wireless signals via the antennas 1410. Although FIG. 10 shows an example in which one RF circuit 1427 is connected to one antenna 1410, the present disclosure is not limited to this illustration, but one RF circuit 1427 can be connected to multiple antennas 1410 at the same time.
