lte scheduling

Basic Introduction of LTE physical layer (1) The LTE physical layer implements significant technological innovation and performance enhancement. Key Technical innovations are mainly embodied in the following aspects: flexible configuration of time-frequency resources using OFDMA as the basic multi-access technology, and significant improvement in spectrum efficiency through MIMO technology; the use of AMC,

Failure phenomenon:The first time to open "Lenovo understand the Internet", did not appear input Lenovo account and password interface, but prompted: "Mobile network has not yet opened." This condition is run in connection with WiFi and you see the LTE icon in change adapter settings is not enabled.Reason Analysis:The use of pre-installed WIN10 system, in the WIN10 system under the flight mode has a separate set of wireless network, Bluetooth,

Designed for the 3g/lte Core networ

Recently, Shanghai released the "12th Five-Year Plan" for the development of the communications industry (hereinafter referred to as the "Plan"), proposing that by the end of the "12th Five-Year Plan", the number of mobile phone users would reach 30 million, 3G and LTE accounts for over 70% of users. According to the plan, by the end of the 12th Five-Year Plan, the number of telephone users in Shanghai reached 38 million, and the number of fixed phon

was opening quickly, which led us to the station, but too late.In the case of slow channel changes, such as indoor or nomadic access services in large cities, it is necessary to use the closed-loop MIMO to further improve the performance of the shampoo.Closed-loop system is the receiving end of the information channel feedback to the transmitter, and then the transmission of data encoding, beamforming or antenna selection and other operations.The feedback method is divided into full feedback or

ICIC:Inter Cell interference coordination, inter-cell interference coordination technology. For cellular network cell throughput is the key limit of the target is the cell disturbance, especially the cell edge users. Because the LTE system supports a frequency multiplexing factor of 1, the meticulous management of inter-cell interference is particularly important.The Icic design guideline is to increase the throughput of edge users without decreasing

Redirection in LTE means that the system uses redirectedcarrierinfo in the rrcconnectionrelease message to indicate that the UE will attempt to reside in the specified system/frequency point after leaving the connection state.LTE supports intra-system redirection and bidirectional inter-system redirectionCommunity redirection is divided into based onMeasurementAndNon-MeasurementU when you select measurement-based redirection, after receiving the measu

The format is one map bar item per line: /etc/network/interfaces: Host network interface configuration file, both Ifup and Ifdown commands depend on it./ETC/RESOLV.CONF: Name Server (DNS) configuration file, and actually /etc/resolv.conf is a linked file that points

Can I combine networking?EPS HSS and HLR are respectively responsible for 4G user data and 2G/3G user data storage, the two main differences are:(1) different stored data, including user dynamic information and static contract data, HSS storage user 4G dynamic i

4g lte network protocol vulnerability discovered by researchers Recently, four US university researchers have discovered problems with the 4g lte protocol. This vulnerability can be exploited to fabricate false information and monitor users and address tracking. In the current phase of 5G deployment, we should also pay attention to the 4G problem discovered this time: the vulnerability is found in the

1. Why you need to add system information change mechanismFrom the LTE System Information (2)-sib Cycle Schedule We already know that the most of the system information required by UE is contained in different SIB blocks, which are broadcast to UE by SIB1 messages and SI messages, respectively. These parameters will not change in general, but there is no absolute, considering that some parameters may need to be modified in some specific cases, such as

In this era of rapid development of network information, 3G networks are currently difficult to meet people's current needs, and 4G networks have gradually entered people's lives. The competition is also intense. A 3G competition is about to kick off. A 4G network competition has already begun, and the three major operators will be able to see how they leverage the world's largest Chinese market to shake a global industrial chain. This leads the world's network development. TD-

What are the LTE downlink reference signals and upstream reference signals?In R9, the downlink defines four reference signals, respectively, for the cell-specific reference signal (C-RS), the user-specific reference signal (UE-RS, also known as Dm-rs), MBSFN reference signal, position reference signal (P-RS).In R10, the downlink defines five reference signals, namely, the cell-specific reference signal (C-RS), the user-specific reference signal (UE-RS

This paper mainly describes the difference between competitive access and non-competitive access process under different scenarios.In the article "LTE-TDD Random Access Process (1)-purpose and classification" has been mentioned that random access can be divided into two types: competitive access and non-competitive access.Competitive scenarios include:(1) Initial access of UE(2) the reconstruction of UE(3) The UE has uplink data sent, but the uplink o

In a wireless network, a device (such as ENODEB) sends data to another device, such as a UE, by block. The sender uses the data in the block to calculate a CRC and sends it along with the block to the receiving end. The receiving end calculates a CRC based on the received data and compares it with the received CRC, and if the two are equal, the receiving end is deemed to have successfully received the correct data and reply an "ACK" to the sender; If the two are not equal, the receiver thinks th
