Buffer Status Report (BSR)
When introducing Sr, we know that the resources required for uplink data transmission are obtained through BSR, the buffer status report process is used to provide the service ENB with information about how much data the UE has to send in the upstream buffer. RRC uses the configured two timers.Periodicbsr-timerAndRetxbsr-timerAnd for each logical channel through signaling indicati

xTable of Contents [1] lexical [2] dynamic front wordsMost of the time, the main reason we are confused about scopes is whether we should make variable lookups in terms of the nesting order of function locations or in the order in which functions are called. Coupled with this mechanism of interference, so that variable lookup is very error-prone. This is actually caused by the two scope work model, which is divided into lexical
Concept:A static scope refers to a piece of code that has its scope defined before it executes, simply to determine where it can be applied (variables) before it executes.A dynamic scope determines its scope, and the scope chain, when the code executes.Static scope:var a = t
In the previous article "Scopes keywords (keyword) and departments discussion (English video)", we have done some basic introduction to the keyword in scope. But we don't have a corresponding tutorial. In this article, we'll show you how to use keyword with Youku scope so that a scope can be rendered differently in different aggregation scopes.If you are not fami

The scope is one of the most important concepts of JavaScript, and to learn JavaScript well you need to understand how JavaScript scopes and scope chains work. Today's article provides a simple introduction to JavaScript scope and scope chain, hoping to help you learn more about JavaScript.

Any programming language has the concept of scope, in short, the scope is the accessibility of variables and functions, that is, the scope controls the visibility and life cycle of variables and functions. In JavaScript, the scope of a variable has two kinds, global

The scope of a variable is the region of the variable that is defined in the program's source code.

Ref: 1190000002773689Whenever an instruction is created, there is an option to inherit its own parent scope (typically the scope or root scope ($rootScope) provided by the external controller), or to create a new scope of its own, of course angularjs for our instructions. The scope

In a recent lecture on JavaScript on the podcast, many friends feel that JavaScript is so simple, but I don't know how to use it, so I have some content for you to share.This series focuses on the content of the advanced part of JavaScript, including
in the 12th chapter of the description of variable objects, we already know that the data of an execution context (variables, function declarations, and formal parameters of functions) is stored as attributes in the variable object. We also know that the variable object is created each time the context is entered, and the initial value is filled in, and the update of the value appears in the Code execution phase. This chapter deals with more details that are directly related to the execution con
ObjectiveIn the 12th chapter, in the description of variable objects, we already know that the data (variables, function declarations, and function parameters) of an execution context are stored as attributes in the variable object.
We also know that the variable object is created each time the context is entered, and the initial value is filled in, and the update of the value appears in the Code execution phase.
This chapter is devoted to more details directly related to the execution context,
Global variablesScope: Global scope (global variables can be used for all source files only if they are defined in one source file.) )Life cycle: Program run time is always presentReference method: The global variable to be referenced must be declared with the extern keyword in other files.Memory Distribution: Global Data areaNote: If a global variable of the same name is defined in two files, the connection error: variable redefinitionGlobal static v
It can be said that each mybatis is centered on a sqlsessionfactory instance. Sqlsessionfactory instances can be built by Sqlsessionfactorybuilder. One is that the sqlsessionfactory can be built in the form of an XML configuration file, and the second is built through the Java API. However, there is a configuration through which all the configurations are implemented through the config instance.This article is intended to implement the scope and life
