The method of transmitting data is applicable to the UE and includes: transmitting, by the UE, duplicated transmission data to different radio link control (RLC) entities respectively when a network side configures or activates a packet duplication mode for a bearer; transmitting, by one of the different RLC entities, the transmission data through one of logical channels to a master medium access control (MAC) entity and transmitting, by each of the others of the different RLC entities, the transmission data through a different one of the logical channels to a different one of one or more secondary MAC entities; and transmitting, by the master MAC entity and the one or more secondary MAC entities, the transmission data to the network side through different carriers.
Abstract:
Disclosed are a relay terminal reselection method and device. A control node performs relay terminal reselection judgement for a source terminal according to a reselection triggering condition of a relay terminal, and if deciding to perform relay terminal reselection, the control node determines a candidate relay terminal list for the source terminal and determines a destination a destination relay terminal for the source terminal from the candidate relay terminal list according to auxiliary information, wherein the control node is the source terminal or a source relay terminal, such that when in the moving process of the source terminal, a target node and the source relay terminal, the source relay terminal is no longer suitable to be used as a relay terminal, the source terminal or the source relay terminal can reselect a relay terminal for the source terminal.
Abstract:
A method, device and system for interacting link information, which are used for solving the problem that at present there is no solution for a network side to learn the link information about a terminal supporting D2D communications and how to distinguish D2D link information from D2N link information. A link information reporting method in the embodiments of the present invention comprises: a terminal supporting D2D communications determining link information which is required to be reported to a network side, wherein the link information comprises D2D link information and/or D2N link information; and the terminal sending the determined link information to the network side on a D2N link, and indicating a link corresponding to the link information to the network side. Using the method in the embodiments of the present invention enables the network side to learn the link information about the terminal supporting the D2D communications and to distinguish whether the received link information is for the D2D link or the D2N link, so that the network side can more accurately manage and schedule the D2D link and the D2N link.
Abstract:
A buffer state reporting method, a UE, a method of processing a buffer state report and a network side device are provided. The buffer state reporting method includes: determining, by the UE, whether a buffer state reporting triggering condition is met; and reporting, by the UE, buffer state information to a network side device if the buffer state reporting triggering condition is met, wherein buffer state information of a plurality of logical channels corresponding to a same bearer for which a data packet duplication mode is configured/activated are reported separately.
Abstract:
A system message transmission method, transmission device, reception method reception device and a storage medium are provided. The transmission method includes determining, by a network side device, sets to which each of system messages to be transmitted belongs, wherein the sets include a basic system message set and a specific system message set; determining, by the network side device, a transmission mode of each of the system messages, wherein the transmission mode of system messages in the basic system message set is a broadcast transmission mode, and the transmission mode of system messages in the specific system message set includes a broadcast transmission mode and/or a demand-based dedicated signaling transmission mode.
Abstract:
An access method and an access device for a radio network are provided. The access method includes: receiving, by a distributed processing node, an Msg1 message from a UE, the Msg1 message including a dedicated access code or sequence; and transmitting, by the distributed processing node, an Msg2 message configured to respond to the Msg1 message to the UE, the Msg2 message including a temporary RNTI which is a currently-unused RNTI in a set of RNTIs available for the distributed processing node.
Abstract:
A network side device according to embodiments of the present disclosure notifies a first correspondence between PPPs and LCG IDs of each target address to a UE, determines the PPPs corresponding to the LCG IDs of each target address in a sidelink BSR MAC CE in accordance with the first correspondence, and then allocates a resource for each target address of the UE in accordance with the determined PPPs and buffer status information corresponding to the LCG IDs of each target address in the sidelink BSR MAC CE.
Abstract:
The present disclosure provides a resource allocation method and a resource allocation equipment for D2D signal transmission. The resource allocation method includes steps of: determining, by a base station, a resource allocation mode to be adopted by a UE, the resource allocation mode including a network scheduling mode and a UE autonomous selection mode; and transmitting, by the base station, configuration information to the UE, the configuration information including at least one of: indication information indicating whether or not the UE is permitted to determine a resource in accordance with the network scheduling mode and/or UE autonomous selection mode, QoS information of a D2D service corresponding to each resource allocation mode, and resource allocation information for determining the resource in the case that the UE adopts the UE autonomous selection mode.
Abstract:
Disclosed are a data transmission method and device for device to device (D2D) communication, the method comprising: determining D2D communication destinations corresponding to a user equipment (UE) of a transmitting end; allocating a corresponding resource for each D2D communication destination; according to the resource corresponding to each D2D communication destination, generating a medium access control protocol data unit (MAC PDU) corresponding to the D2D communication destinations, and transmitting the MAC PDUs using the resource corresponding to the D2D communication destinations. The present invention separately generates a MAC PDU for each D2D communication destination of a UE of a transmitting end, thus preventing the data from one device to different D2D communication destination devices from being multiplexed into one MAC PDU, further reducing header overhead of the MAC PDU and eliminating unnecessary blind detection of a device of a receiving end, thereby saving power.
