LTE downlink Physical layer transport mechanism (1)-Antenna port antenna port and cell specific reference signal CRS

In the Last Post, "LTE Physical Transmission Resources (3)-time-frequency resources," the final mention of Pcfich and other downstream physical channels, this blog post originally wanted to write Pcfich channel, but in preparation for writing Pcfich, found the need to use the antenna port related content, and these content is not yet written. So this paper first write the antenna port and downlink reference signal related content.1. Relationship of an

The EPC allows the use of IPV4 networks to connect to LTE devices. In other words, conventional ns-3 applications and IPV4 sockets

The method of importing DBM data into MySQL database

First of all, I used Perl to save files in the DBM database with more than 50,000 records and 15 fields per record. Now want to use MySQL, to the record guide over. The first step, all the DBM records are imported into a text file, each field is separated by a tab ("T"), and the end of each line wraps. The second section reads the data into an array and opens the database and defines preprocessing as foll

What does VoWi-Fi bring to the voice communication experience in the LTE age?

What does VoWi-Fi bring to the voice communication experience in the LTE age? In the Internet era, users have high requirements on business experience, including voice services. To some extent, this can be explained that compared with the global LTE construction climax, the VoLTE business is growing more slowly. As the first telecom-level public voice service, VoLTE puts forward high requirements on the op

Ack/Nack bundling and multiplexing in TDD LTE

In tdd lte, upper and lower lines are not necessarily symmetric. When the number of downstream sub-frames is higher than that of the upstream sub-frames, the harq of multiple downstream sub-frames is reported in one upstream sub-frame. The number of harq records reported in an uplink sub-frame depends on the configuration of the LTE uplink and downlink MIMO modes. Through upper layer configuration,

LTE CAT1 to CAT10, CAT0 and the Internet of Things

Cat. That is ue-category, according to the definition of 3GPP, ue-category is divided into 1~10 a total of 10 levels, of which cat.1-5 is R8 definition, cat.6-8 is R10 definition, cat.9-10 is R11 definition. As shown above, ue-category mainly defines the upper and lower line rates that the UE terminal can support. The cat.0 is an LTE terminal grade that is written to the 3GPP rel.12 Standard and supports a lower-rate, lower-power version. cat.0 and

"Turn" db/dbm

DB, which represents a relative value. When calculating A's power compared to b large or small number of db, can be calculated as the formula 10LG A/b. For example: A power is one-fold larger than B power, then 10lg A/b = 2 lg = 3dB, that is, the power of a is greater than the power of B 3dB; If the power of a 46dbm,b is 40dBm, it can be said that a is greater than B 6dB; if the a antenna is 12dBm, b antenna is 14dBm, can say a than B small 2dB.

Brief Introduction to the development status of LTE access Bearer Network

At present, LTE access bearer network is not widely used, but there are still many problems. So I have studied the development status and problems of the LTE access bearer network. I will share with you here, hoping it will be useful to you. From 2G/3G to LTE access bearer network, more than 90% of wireless site addresses will be reused, and 2G/3G will coexist wi
