The UTRAN long-term evolution (LTE) specifications provide flexible means to achieve micro-sleep operation for user equipment (UE) even though it is in active mode and running a service.

Long term evolution (LTE) is the next step forward in cellular 3G services. LTE technology is a based on a 3GPP standard that provides for a downlink speed of up to 150 megabits per second (Mbps) and an uplink speed of up to 50 Mbps. Fixed wireless and wired standards are already approaching or achieving 100 Mbps or faster, and LTE is a way LTE Standby CDRX Standby (10 MHz) CDRX Standby (20 MHz) 3G (WCDMA) Talk) 3G (HSDPA) 7.2 Mbps 3G (HSDPA) 21 Mbps LTE Cat 3 10 MHz (68/23 Mbps) LTE Cat 3 20 MHz (100/50 Mbps) LTE Cat 3 20 MHz (150/50 Mbps) Standby Active Snapdragon Competitor C Jul 14, 2017 · DRX used in Idle state is called Idle mode DRX and one in Connected state is called Connected mode DRX (C-DRX). Idle mode DRX is related to paging, and thus used in 3G as well. C-DRX was defined with the arrival of LTE. - RRC_Idle state: When radio connection (RRC connection) between base station and device Jan 15, 2019 · With legacy LTE (4G) it was decided that all devices (UE) should be capable of the maximum carrier bandwidth of 20MHz (UE can also support 10/15/5/3 MHz).

See full list on ericsson.com Discontinuous Reception (DRX) is one of the battery-saving technologies that are used in LTE. It allows devices to enter sleeping mode (RF transceiver off) when there is no traffic, and wake up entering active mode (RF transceiver on) and deliver traffic when there is traffic. Operating a UE device having a single radio configured to communicate using a first and second RAT. The UE may begin operating in a connected discontinuous reception (CDRX) mode of the first RAT, Figure 1 shows a cDRX paging event. The average current, length and charge within the cursors are given in the OPP plot, as shown in figure 3. The maximum current (44,4 mA) is not included in the OPP plot. Figure 2 shows the average current during the cDRX paging, the average current is given in the RRC connected mode table, as shown in figure 3. As you know, SFN (System Frame Number) and Subframe is the timer being used in current LTE for most of the synchronized operation.

Discontinuous reception (DRX) is a method used in mobile communication to conserve the battery of the mobile device.. The mobile device and the network negotiate phases in which data transfer occurs. During other times the device turns its receiver off and enters a low power state.. This is usually a function designed into the protocol that allows this to happen - most notably how the

Here we will try to give general idea for DRX feature in Idle Mode and Connected Mode. This is why the sleeping mode is called 'Discontinuous Reception'. There are largely two types of DRX in LTE. One is Idle mode DRX. This idle mode DRX is more commonly known as Paging Cycle which is explained in detail in Pagingpage. The other type is called C-DRX (Connected Mode DRX) which is described in C-DRXpage. C-DRX: Connectedmode DRX,连接态下的DRX. UE在连接态下，如果没有数据传输的话，会根据DRX的规则停止监听PDCCH (监听PDCCH可参考：PDCCH),从而达到省电的目的。.

This was a reasonable assumption at the time given the relatively modest bandwidth compared to NR, Whereas NR is designed to support very wide bandwidths up to 400MHz (for FR2) and 100Mhz In long term evolution (LTE) network, CDRX is controlled by the radio resource control (RRC) protocol. RRC signaling sets a cycle where the user equipment's (UE) receiver is operational for a certain period, typically when all the scheduling and paging information is transmitted.

(cdrx); % So after the Turbo decoding, it will have 4096 bits rather than 4032 bits, due to addition of filler bits and CRC. DRX (Discontinuous Reception) is a basic LTE feature, eDRX (extended DRX) is used in LTE-M and NB-IoT. Interested Parties: Orange (Grenoble), Orange (Cairo), B-Com, Fujitsu I'm requesting a feature (since I can't find a way to do this?) to read all relevant LTE network parameters from the connected network when using the nRF9160. When using the Online Power Profiler there are some parameters that need to be entered. It would be good if these parameters could be read from the nRF9160.

Even though CDRX is a very important feature in terms of energy saving on UE side and a lot of live network enables this feature, it is not the mandatory requirement on UE. Therefore, even though most of UE would support this feature, there would be some UE (especially UE released at very early stage of LTE) that may not support this feature.
