Description

Technical Field

[0001] The present disclosure relates to the field of communication technologies, and particularly to a method, apparatus, and storage medium for determining a support resource set.

Background Art

[0002] Since Long Term Evolution (LTE), the Third Generation Partnership (3GPP) has been developing the specification of Sidelink (SL, also called direct link) as the specification for direct communication from terminal to terminal. In July 2020, the first specification of New Radio (NR) Sidelink was completed in Release 16 (hereinafter abbreviated as Rel-16), and the solution of NR Sidelink in it is mainly used for Vehicle to Everything (V2X) and public safety. For V2X and public safety, due to time constraints, Release 16 does not fully support service requirements and operation plans, and Service and System Aspects (SA) makes some extensions in Release 17 NR Sidelink, for example, extensions of the architecture and system to support advanced V2X services for 3GPP. In addition, the SA working group is considering other business use cases related to NR Sidelink, such as network control interactive services, enhanced energy efficiency relays, wide coverage, and creation of audio-visual services. Therefore, at the 86th plenary session of 3GPP, when initiating Release 17, the extension of NR Sidelink is set as a work item, aiming at extending the reliability of Sidelink transmission and reducing latency.

[0003] In the expansion of NR Sidelink, for user equipment A in sidelink communication, one assistance resource set can be transmitted to user equipment B with a resource selection method of mode 2, and user equipment B considers it when performing resource selection for its own data transmission. However, in related technologies, when user equipment A transmits an assistance resource set, since the number of resources in the sensed assistance resource set is large, the signaling overhead for user equipment A to transmit the assistance resource set becomes large.

[0058] Here, exemplary embodiments will be described in detail, and examples thereof will be shown in the drawings. When the following description relates to the drawings, unless otherwise expressed, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices and methods consistent with some aspects of the present disclosure described in detail in the scope of the appended claims.

[0059] The support resource set determination method provided by the embodiments of the present disclosure is applicable to the sidelink communication system shown in FIG. 1. As shown in FIG. 1, in a scenario where sidelink communication is performed between sidelink communication devices, the network device sets various transmission parameters for data transmission to sidelink communication device 1. Sidelink communication device 1, sidelink communication device 2, and sidelink communication device 3 perform sidelink communication. There may be an obstacle between sidelink communication device 2 and sidelink communication device 3. The link for communication between the network device and the sidelink communication device is an uplink / downlink, and the link between sidelink communication devices is a sidelink.

[0060] In the present disclosure, the communication scenario of direct communication between sidelink communication devices may be a Vehicle to Everything (V2X) service scenario. Here, V represents an in-vehicle device, and X represents any object that interacts with the in-vehicle device. Currently, X mainly includes in-vehicle devices, handheld devices, roadside infrastructure, and networks. The information patterns of V2X interactions include interactions between in-vehicle devices (Vehicle to Vehicle, V2V), between in-vehicle devices and roadside devices (Vehicle to Infrastructure, V2I), between in-vehicle devices and handheld devices (Vehicle to Pedestrian, V2P), and between in-vehicle devices and the network (Vehicle to Network, V2N).

[0061] With the development of the next-generation 5G mobile communication technology, in 3GPP Rel-16, by using 5G NR technology, support for new V2X communication services and scenarios such as Vehicles Platooning, Extended Sensors, Advanced Driving, and Remote Driving has been realized. Generally speaking, 5G V2X sidelink can provide higher communication speed, shorter communication delay, and higher reliability communication quality.

[0062] The communication scenario of direct communication between side communication devices may be a device - to - device (D2D) communication scenario. The side communication devices performing direct communication in the embodiments of the present disclosure can include various handheld devices with wireless communication functions, in - vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, and various forms of user equipment (UE), mobile stations (MS), terminals, terminal equipment, etc. For the sake of easy explanation, the embodiments of the present disclosure will be described by taking the following side communication devices as user equipment as an example.

[0063] Here, through the extension of NR Sidelink, the transmission reliability can be improved and the time delay can be reduced. In the extension of NR Sidelink, in terms of extending mode 2 resource allocation, the 3GPP working group concluded that it is necessary to consider a method to assist resource selection between user equipment. In this method, two user equipment are defined. For example, user equipment A is the assisting user equipment of user equipment B, and user equipment B refers to the user equipment that needs to perform resource selection for the data transmitted by itself. Here, user equipment A determines a resource set and transmits it to user equipment B in the mode 2 manner. When user equipment B performs resource selection, it can be understood that user equipment B considers the assisting resource set transmitted from user equipment A, that is, user equipment B performs resource selection using the assisting resource set cooperation mechanism. Here, user equipment B can transmit data to user equipment A and / or other user equipment.

[0064] However, when the user equipment A transmits a support resource set, if all candidate support resource sets sensed by the user equipment A are transmitted to the user equipment B via control signaling, when the number of resources in the sensed candidate support resource set is large, it will result in a large overhead of control signaling.

[0065] To reduce the overhead of control signaling, embodiments of the present disclosure provide a support resource set determination method, in which the user equipment A selects some time-frequency resources from the sensed candidate support resource sets Support resource set as, and reports this Support resource set to the user equipment B, reducing the number of resources reported by the user equipment A to the user equipment B, and assisting the user equipment B to perform resource selection.

[0066] In the embodiments of the present disclosure, for the sake of easy explanation, the device that provides support resources is called the first device, and the device that performs resource selection using a support resource set cooperation mechanism is called the second device.

[0067] FIG. 2 is a flowchart of a support resource set determination method shown by an exemplary embodiment. As shown in FIG. 2, the support resource set determination method is applied to the first device and includes the following step S11.

[0068] In step S11, Support resource set is determined.

[0069] Here, Support resource set includes some time-frequency resources in the candidate support resource set sensed by the first device.

[0070] The support resource set determination method provided by the embodiments of the present disclosure selects some time-frequency resources in the candidate support resource set sensed by the first device Support resource setBy determining as such, the number of resources reported to the second device can be reduced, and furthermore, the signaling overhead can be reduced.

[0071] FIG. 3 is a flowchart of a method for determining a support resource set shown by an exemplary embodiment. As shown in FIG. 3, the method for determining a support resource set is applied to a first device and includes the following steps.

[0072] In step S21, Support resource set is determined.

[0073] Here, Support resource set includes some time-frequency resources within the candidate support resource set sensed by the first device.

[0074] In step S22, Support resource set is transmitted.

[0075] The method for determining a support resource set provided by an embodiment of the present disclosure determines some time-frequency resources within the candidate support resource set sensed by the first device as Support resource set and, by transmitting this Support resource set to the second user equipment, the number of resources reported to the second device can be reduced, and furthermore, the signaling overhead can be reduced.

[0076] In an embodiment of the present disclosure, the second device receives Support resource set transmitted from the first device and, when performing resource selection, can perform resource selection using a support resource set cooperation mechanism in consideration of Support resource set transmitted from the first device.

[0077] FIG. 4 is a flowchart of a method for determining a support resource set shown by an exemplary embodiment. As shown in FIG. 4, the method for determining a support resource set is applied to a second device and includes the following step S31.

[0078] In step S31, Support resource set is received.

[0079] Here, Support resource set includes some time-frequency resources within the candidate support resource set sensed by the first device.

[0080] In an embodiment of the present disclosure, the second device Support resource set receives, and this Support resource set includes some time-frequency resources within the candidate support resource set sensed by the first device, and the signaling overhead for the second device to receive the support resource set can be reduced.

[0081] Embodiments of the present disclosure will hereinafter describe Support resource set sent from the first device and / or Support resource set received by the second device.

[0082] In one embodiment, in the support resource set determination method provided by the embodiments of the present disclosure, Support resource set may be a resource list ( l ist).

[0083] Here, in the embodiments of the present disclosure, Support resource set The resource list to be used has a list length, hereinafter referred to as the first list length.

[0084] In the support resource set determination method provided by the embodiments of the present disclosure, the first device reports Support resource set in the form of a resource list, and can report a resource list with the first list length. Assume that the first list length is L. The first device reports Support resource set in the form of a resource list, and reports a Support resource set with a list length of L.

[0085] In the method for determining a support resource set provided by an embodiment of the present disclosure, a second device receives a resource list with a list length of L, and based on this resource list, Support resource set can be determined.

[0086] Here, in the method for determining a support resource set provided by an embodiment of the present disclosure, the Support resource set first list length of the resource list in the form may be a fixed list length. For example, the first list length is a preset fixed list length.

[0087] In an embodiment of the present disclosure, when determining Support resource set , the first device can be determined based on the resource selection window of the second device. Here, the second device conveys the resource selection window of the second device to the first device in a support request transmitted to the first device via control signaling. The first device numbers the resources in the sensed candidate support resource set and the resource selection window of the second device to form a resource list. Here, the method of numbering the resource list is something that the first device and the second device have agreed on in advance. In other words, both the first device and the second device can determine the resource list and the number of the resource list. Here, the resource list number is numbered with a frequency domain unit in the frequency domain and a time domain unit in the time domain as the granularity. The frequency domain unit may be a channel, a subchannel, a subband, a band, etc. The time domain unit may be a slot, a radio frame, a subframe, a mini-slot, a symbol, a transmission time interval (TTI), etc. In an embodiment of the present disclosure, the resource list number is numbered with a subchannel in the frequency domain and a slot in the time domain as the granularity, but the present disclosure is not limited thereto.

[0088] In the support resource set determination method provided by the embodiments of the present disclosure, Support resource set It may be a time-frequency resource that is randomly selected from the candidate support resource set and conforms to the first list length. That is, in the embodiments of the present disclosure, the first device selects a time-frequency resource that conforms to the first list length from the candidate support resource set Support resource set and can be randomly selected as.

[0089] FIG. 5 is a schematic diagram of a first device randomly selecting a time-frequency resource that conforms to the first list length from a candidate support resource set sensed by the first device as a support resource set in an exemplary embodiment of the present disclosure. As shown in FIG. 5, the candidate support resource set sensed by the first device performs resource list numbering with subchannels in the frequency domain and slots in the time domain as the granularity. As shown in FIG. 5, the time-frequency resources in the resource list are the candidate support resource set sensed by the first device. Assuming that the first list length L = 8 is preset, the first device randomly reports a resource list with a list length of 8 in the candidate support resource set. For example, randomly select time-frequency resources with numbers {2, 4, 5, 7, 8, 10, 12, 20} Support resource set and can be transmitted to the second device as.

[0090] In the support resource set determination method provided by the embodiments of the present disclosure, Support resource set It may be a time-frequency resource that is selected from the candidate support resource set based on the Reference Signal Receiving Power (RSRP) and conforms to the first list length. That is, the first device selects a time-frequency resource that conforms to the first list length from the sensed candidate support resource set based on the RSRP Support resource set as.

[0091] In one embodiment, the first device selects time-frequency resources that match the first list length from the candidate assistance resource set in ascending order of the received reference signal power value.

[0092] FIG. 6 shows a time-frequency resource that matches the first list length from a candidate assistance resource set sensed by a first device based on RSRP in an exemplary embodiment of the present disclosure. Support resource set It is a schematic diagram of selection. As shown in FIG. 6, within the time period Tproc,0 of the candidate assistance resource set sensed by the first device, among the monitored resources, the RSRP values of the demodulation reference signals (DMRS) of the measured physical sidelink control channels (PSCCH) are sorted in ascending order, and resources with lower RSRP values are preferentially selected. According to the list length L of the preset reported resource list, the first device selects resources with a list length of 8 and lower RSRP values, such as {5, 7, 8, 10, 12, 20, 22, 25}, and these time-frequency resources have the least interference for data transmission by the second device. The time-frequency resources numbered {5, 7, 8, 10, 12, 20, 22, 25} are Support resource set transmitted to the second device.

[0093] In the assistance resource set determination method according to the embodiment of the present disclosure, the first list length of the reported resource list is preset, and the first device belongs to the candidate assistance resource set sensed by the first device, and the assistance resource set with a length of L is Support resource set reported as.

[0094] In the assistance resource set determination method provided by the embodiment of the present disclosure, the first list length of the resource list may be a preset fixed list length. On the other hand, it may be a flexible and dynamically changing list length.

[0095] In one embodiment, in an embodiment of the present disclosure, the first list length is determined based on the minimum ratio satisfied by the ratio between the resources in the candidate support resource set and the resources in the resource selection window of the second device.

[0096] Here, in an embodiment of the present disclosure, for ease of explanation, the minimum ratio satisfied by the ratio between the resources in the candidate support resource set and the resources in the resource selection window of the second device is referred to as the first ratio. Here, based on the communication protocol R16, in order to ensure the randomness of resource selection, the ratio between the resources in the candidate support resource set determined in step 1 of resource sensing and the resources in the resource selection window needs to satisfy the requirement of ≧ X% (the first ratio). Here, X% is defined by the protocol, thus ensuring that there are more resources and satisfying the randomness of resource selection.

[0097] In one embodiment, in the candidate support resource set determination method provided by the embodiment of the present disclosure, a ratio offset value (Y%) with respect to the first ratio can be set. The first list length is determined based on the ratio offset value with respect to the first ratio.

[0098] In one embodiment, in an embodiment of the present disclosure, the first list length can be determined based on the number of resources in the resource selection window of the second device, the first ratio, and the ratio offset value with respect to the first ratio. For example, the first device determines the first list length by L = S * (X% + Y%). Here, S is the number of resources in the UEB resource selection window, X% is the first ratio, Y% is the ratio offset value with respect to the first ratio, and L is the first list length.

[0099] Here, in the embodiments of the present disclosure, the ratio offset value Y% for the first ratio is preset by Radio Resource Control (RRC). The number of resources S within the UEB resource selection window is calculated based on the position within the resource selection window. Here, the first device obtains the position of the resource selection window according to the assistance request of the second device.

[0100] In the embodiments of the present disclosure, the first device notifies the second device of the determined resource list via control signaling by calculating the first list length of the resource list. The first device randomly selects, from the sensed candidate assistance resource set, one resource list with a list length of L Support resource set and reports it to the second device. By determining the first list length based on the number of resources within the resource selection window of the second device, the first ratio, and the ratio offset value for the first ratio, the reported first list length changes according to the number of resources within the candidate assistance resource set sensed by the first device, making the solution more flexible.

[0101] In a possible embodiment, assuming that the first ratio X% is 40%, when the first device performs candidate assistance resource set sensing, the finally determined resource ratio needs to satisfy being greater than X%. For example, in the embodiments of the present disclosure, the ratio of the candidate assistance resource set is set to be 75%. FIG. 7 is a schematic diagram of the candidate assistance resource set determined by the prior art. As shown in FIG. 7, the first device needs to select 21 time-frequency resources from 28 time-frequency resources and transmit them to the second device as assistance resources.

[0102] FIG. 8 is a schematic diagram showing that a first device determines a first list length based on the number of resources, a first ratio, and a ratio offset value with respect to the first ratio in a resource selection window of a second device, and performs support resource set determination. As shown in FIG. 8, in an embodiment of the present disclosure, when the first device Support resource set determines, the selected resource needs to satisfy being greater than the first ratio X% and less than (X% + Y%). Assuming that the first ratio X% is 40% and (X% + Y%) is 50%, the first device can select 12 time-frequency resources from 28 time-frequency resources and transmit them to the second device as support resources.

[0103] Here, the first device can select 12 time-frequency resources from 28 time-frequency resources and transmit them to the second device as support resources, and compared with selecting 21 time-frequency resources from 28 time-frequency resources and transmitting them to the second device as support resources, the number of reported support resources can be reduced, and the signaling overhead can be reduced.

[0104] In the support resource determination method provided by the embodiment of the present disclosure, the first device can determine based on the resource selection window of the second device Support resource set can be determined.

[0105] In one embodiment, Support resource set is a time-frequency resource having a first slot length within the resource selection window of the second device. Here, the first slot length is smaller than the slot length within the resource selection window of the second device.

[0106] In one embodiment, the support resource set is determined based on a first time and is a continuous time-frequency resource having a first slot length. Here, the first time is the start time or the end time of the resource selection window of the second device.

[0107] FIG. 9 is a schematic diagram showing that a first device according to an exemplary embodiment of the present disclosure can determine based on a resource selection window of a second device Support resource set As shown in FIG. 9, user equipment A is before slot n+T2 at the end position of the resource selection window of selected user equipment B, and selects time-frequency resources of L slots (L≤the number of slots in the resource selection window of user equipment B, and the value of L is preset by RRC) with a fixed slot length Support resource set and reports it to user equipment B.

[0108] Here, the position of slot n+T2 at the end position of the resource selection window of user equipment B is notified by user equipment B to user equipment A in an assistance request via control signaling. Here, the value of slot length L is preset via RRC signaling.

[0109] In the embodiment of the present disclosure, user equipment A knows the resource selection window [n+T1, n+T2] of user equipment B. Here, user equipment A senses the time-frequency resources within the resource selection window of user equipment B, but selects the time-frequency resources with a reporting slot length of L Support resource set and reports it to user equipment B. That is, one time-frequency resource subset of the time-frequency resources within the resource selection window of user equipment B is reported.

[0110] The assistance resource set determination method provided by the embodiment of the present disclosure is such that a first device selects a resource within the resource selection window of a second device and smaller than the slot length within the resource selection window of the second device Support resource set and transmits it to the second device, thereby reducing the number of assistance resources to be transmitted and reducing the signaling overhead.

[0111] Note that the method for determining a support resource set provided by an embodiment of the present disclosure can be applied to an interaction process in which a first device and a second device transmit and receive a support resource set. Regarding the process in which the first device and the second device interact to realize the transmission and reception of the support resource set, the first device and the second device have corresponding functions for realizing the method for determining the support resource set according to the above embodiment, and the embodiments of the present disclosure will not be described in detail here.
