, and the random access process selects only one of the NZC-length sequences sent to eNB. 4. Interface mappingFor Pusch RB, each sub-carrier accounts for 15K of bandwidth, so 6 RB (12 sub-carriers per RB) is a total of 1.08M of bandwidth. In particular, the RB for the Prach channel, each sub-carrier is 1.25K, so there is a total of 864 sub-carriers. When the UE chooses a certain preamble, it is mapped to 83

phone products to meet the needs of carriers ." Yu Chengdong did not shy away from saying that he was about to cut down more than 80% models in the second half of the year. He said that Huawei relied on operators to sell mobile phones, which led to a lack of distribution channels. According to reports, in 2011, 65% of Huawei's mobile phones were sold by carriers, and the remaining 35% were sold by retaile

organizations, developed 2G, 3G, 4G ,..., Or even nG standard specifications. They have made great efforts in Baseband Communication (corresponding to the BP function of mobile phones) and are promoting the development of the entire industry. The basic difference between smartphones and functional mobile phones is AP + BP (please refer to [5]). The advantages of carriers and traditional communication vendors are BP, BP mainly supports voice calls, te

developers. By providing an urgently needed universal platform for wireless data application development and execution, brew has become an engine for promoting the growth of the entire industry. Developers can write applications faster, quickly enter the mass market, and ensure that benefits can be obtained. OEMs can launch new devices more quickly by doing a very small amount of internal development and integration work. By providing a wide range of applications, content, and services,

For example, the previous time was in more than 20, the word Baidu index is very high, I just want to push it to the first page, every day to give it more to do some outside the chain, the result, not a few days no rankings, ran to 100 away, only to suddenly realize that I was too pushing the word, leading to excessive optimization, Below I think what should do to make Baidu think is natural optimization, the fi

Text, numbers, language, informationnumbers, words and natural languages are the carriers of information, and they are created to record and disseminate information .But it seems that the relationship between mathematics and linguistics is not big, for a long time, mathematics is mainly used in astronomy, mechanics.In this chapter, we will review the development of the information age and see how linguistics is slowly associated with mathematics.Infor

Recently, has been studying, default APN settings When we see from the code and the phone, the default APN display is from the CONTENT://TELEPHONY/CARRIERS/PREFERAPN data, and this is saved through the shared preference, when the first time the phone card boot, After we have preferapn.xml the file, we find that it has been written with a value, but from the Telephonyprovider.java file, we do not find any written place, then the default APN exactly how

There are still many things worth learning about the IP router technology. Here we will mainly introduce the experience of IP phones and IP router technology. There are still many problems to solve when the IP Phone is transferred to the local device. There will be many policy issues to solve, such as operating licenses. There are also problems that need to be solved in different technical and policy fields such as number resources and interconnection between networks. Apart from these problems,

At present, there is no technical problem in upgrading from IPv4 to IPv6. The problem is the industrialization of technology. If we do not push the core technology of computing to industrialization, the final result will be that a pot of good meat will not be able to produce practical significance. Industrialization of IPv6 is a business related to the future of the country and the fate of the enterprise. It is not enough to rely solely on a research institution such as the Institute of computin

Architects need to place HTML5 security first in the form of new attacks The Enterprise Architects we introduced earlier may encounter some problems when starting HTML5. This article will continue to introduce new security attacks as HTML5 functions increase. New Function = New Attack One of the concerns of security experts is that HTML5 stacks can run in both mobile and Web browsers. Shreeraj Shah is the founder and director of a network security attack supply company named Blueinfy Solutions

How and when does carriers get involved? Who is all of the players? How much quicker or fewer steps is there for developer or Google Play editions? When does manufacturers see t

: -AppleIt seems strange that android was developed by its main rival? Let me analyze it. With the unprecedented iPhone success and Apple's arrogant and harsh attitude towards network operators, carriers are eager to find a cheaper option; therefore, the largest operators at the first layer began to use android to develop mobile phones for users who could not afford the iPhone. More importantly, they don't have to pay a 300 euro discount for apple eve

controversial, but we all agree that Google has carefully deployed a series of control points behind the simulated reality of "free openness to everyone" to bring a platform to the public, let Google's main business (advertising) reach more places. At first glance, it seems that android is doing well in this aspect. Google has won many partners (carriers and mobile phone manufacturers) and is supported by developers. Every day, a large number of Andr

the mobile ecosystem. In doing so, they do not realize that HTML5 is a technology that provides capabilities and is still a key factor in the lack of platforms. Successful application platforms have five key factors: 1. Software basics: Manages fragmented APIs and creates a tool set for applications. 2. the developer community uses the same API set for writing, promoting innovation and meeting different application scenarios. 3.
