example 1

[0332] In this example, the resource allocation method specifically includes the following steps:

[0333] Step a1: The terminal determines the mapping relationship between logical channels and logical channel priority restriction parameters.

[0334] Here, the mapping relationship between logical channels and logical channel priority restriction parameters is determined by the terminal itself.

[0335] Specifically, determining the mapping relationship between logical channels and logical channel priority restriction parameters may include:

[0336] Determine the mapping relationship between the logical channel and the logical channel priority limit parameter through the terminal high layer;

[0337] Or, determine the mapping relationship between the logical channel and the logical channel priority restriction parameter based on the indication information of the high layer through the terminal MAC layer or the RRC layer;

[0338] Alternatively, the RRC layer or the MAC layer ...

example 2

[0371] In this example, the resource allocation method specifically includes the following steps:

[0372] Step a2: The terminal obtains the mapping relationship between the logical channel configured by the resource allocation management node and the priority restriction parameter of the logical channel.

[0373] Here, the mapping relationship between logical channels and logical channel priority restriction parameters is completely determined by the resource allocation management node (network side device or group head).

[0374] Specifically, the mapping relationship between the logical channel directly configured by the resource allocation management node and the priority restriction parameter of the logical channel may specifically include:

[0375] The terminal reports the logical channel of each direct communication interface and the radio access technology and / or resource type corresponding to the logical channel of each direct communication interface to the resource a...

example 3

[0396] In this example, the resource allocation method specifically includes the following steps:

[0397] Step a3: The terminal obtains the mapping relationship between the logical channel configured by the resource allocation management node and the priority restriction parameter of the logical channel.

[0398] Here, the mapping relationship between logical channels and logical channel priority restriction parameters is completely determined by the resource allocation management node (network side device or group head).

[0399] Specifically, the mapping relationship between the logical channel directly configured by the resource allocation management node and the priority restriction parameter of the logical channel may specifically include:

[0400] The resource allocation management node directly configures the mapping relationship between the QoS parameters corresponding to the logical channels of the direct communication interface and the priority restriction parameter...

Abstract

The invention provides a resource allocation method, a terminal and node equipment, and solves the problem of how to execute an LCP process of a direct communication interface when the terminal performs data transmission by using the direct communication interface. The resource allocation method comprises the steps of determining a scheduling permission corresponding to the direct communication interface; and performing resource allocation on logical channels of the direct communication interface according to the scheduling permission and a mapping relationship between the logical channels ofthe direct communication interface and logical channel priority limit parameters. According to the invention, after the terminal receives the scheduling permission corresponding to the direct communication interface, data packets can be organized at the direct communication interface, and resource allocation of logical channels of the direct communication interface can be executed.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to a resource allocation method, terminal and node equipment. Background technique [0002] The processing procedure of the LCP (LogicalChannel Prioritization, logical channel priority) of the direct communication interface of the LTE (Long Term Evolution, long-term evolution) system is as follows: [0003] 1) Step 0: Select the destination destination; [0004] Specifically, the destination corresponding to the LC with the highest priority of the currently available data available is selected. [0005] 2) For each MAC (Medium Access Control, Media Access Control) PDU (Protocol DataUnit, Protocol Data Unit): [0006] Step 1: Allocate resources for the LC with the highest priority and data available corresponding to the destination selected in Step 0. [0007] Step 2: If there are remaining resources, allocate resources in descending order to the data av...
