Abstract:
Disclosed are a competition-based resource selection method and device. The method includes that: a first interception result is received in a (n+1)th time domain unit, the first interception result at least including channel occupation information and/or collision information in a nth time domain unit; and a time-frequency resource for data sending is selected according to the first interception result, where n is 0 or a positive integer. The present disclosure also discloses a computer storage medium.
Abstract:
The present document discloses a communication data sending method and device, and user equipment, herein the communication data sending method includes: UE indicating a D2D data channel resource through D2D data channel resource indication information in D2D control indication information and/or index information corresponding to the D2D control indication information; and the UE sending D2D communication data on the D2D data channel resource. Through the present document, the problem that a transmitting UE for D2D communication is unable to indicate the used D2D data channel resource by using an eNB scheduling indication resource in the cellular communication is solved, and the indication of the D2D data channel resource is realized.
Abstract:
The present disclosure provides a method and device for processing Device-to-Device (D2D) communication, a D2D communication device and an Evolved Node B (eNodeB). Wherein, the method includes that: resources configured for Scheduling Assignment (SA) and/or data of D2D communication are divided into M resource groups, each resource group including X ResourceUnits (RUs) formed by N time-domain RUs*K frequency-domain RUs, each RU including O symbols on a time domain and including P subcarriers on a frequency domain, the X RUs in each resource group being configured to configure T logical channels, each logical channel including Num RUs according to a number Num of sending times and locations of each logical channel in the resource groups being determined according to a preset rule; and D2D communication processing is performed according to a determined resource configuration.
Abstract:
Disclosed are a method for determining a resource priority, a processing device, a processing system and a UE. The method for determining the resource priority can include: performing, on a physical sidelink control channel (PSCCH), at least one of the following operations: performing energy detection to obtain a detection result and performing information decoding to obtain a decoding result; and weighting at least one of the detection result and the decoding result to determine a priority of a PSCCH resource, or determining the priority of the PSCCH resource according to at least one of the detection result and the decoding result.
Abstract:
Provided are methods and devices for transmitting or receiving Device-to-Device (D2D) broadcast information, and a transmission system. The method for transmitting the D2D broadcast information includes that: classification information of service information to be transmitted is acquired; control information corresponding to the classification information is acquired, wherein the control information is used for indicating resource scheduling information used during transmission and/or retransmission of the service information; and the service information and the control information are transmitted in a broadcast manner according to a preset rule.
Abstract:
The present disclosure discloses a method, apparatus, device and system for sending device discovery signals. The method includes: acquiring configuration information indicating discovery resources for device discovery; determining discovery resource elements for sending the device discovery signals in a discovery resource period indicated by the configuration information, the discovery resource elements being obtained by dividing radio resources in the discovery resource period in a manner of time division multiplexing and/or frequency division multiplexing; and sending the device discovery signals on the determined discovery resource elements.
