The UE may use Discontinuous Reception (DRX) in RRC_IDLE and RRC_INACTIVE state in order to reduce power consumption.
The UE monitors one Paging Occasion (PO) per DRX cycle.
A PO is a set of PDCCH monitoring occasions and can consist of multiple time slots (e.g. subframe or OFDM symbol) where paging DCI can be sent.
Different UEs based on their UE_ID are divided into the multiple paging groups per every DRX cycle duration and each paging group is linked to a specific Paging Frame(PF). Every Paging Frame (PF) may contain multiple Paging Occasions (POs).
UE first should calculate its Paging Frame(PF) and then identifies its PO within the PF.

Here is an example that 16 UEs with their IDs are going to be paged through 5G NR Air Interface (5G NR Uu) using RRC protocol. I also use all the necessary formulas from 3GPP specs that are vital to calculate the Paging Frames, Paging Occasions and the paging groups.

Netflix: Four things which have driven its success

Image
  Netflix got a big boost from the pandemic last year, as demand for streaming movies and television soared. On Thursday, it shared its full-year results with investors and its plans for next year. Here's what we learned.    1. Netflix is making a lot of money The company now has more than 200 million paid members, up more than 30% from 2019. About 37 million people subscribed last year, including 8.5 million in the last three months alone. The additions - as well as price increases in the US, UK and elsewhere - helped revenue rise 24% in the most recent quarter to $6.6bn (£4.8bn), while profit hit $542m. For the year, it reported nearly $25bn in revenue and almost $2.8bn in profit. Netflix, which has taken on major debt to fuel its expansion, said the gains meant it expects to be able to stop borrowing to finance its operations and is considering using excess cash to buy back shares. The disclosures helped the firm's shares shoot up more than 9% in after-...

Trump decree on Covid visiting rules rebuffed as he enters final day

Image
US President-elect Joe Biden has moved to dismiss a new White House decree on Covid travel rules, as Donald Trump enters his final full day in office.   In one of his last orders, Mr Trump had tried to end travel bans for visitors from much of Europe and Brazil. Mr Biden's spokeswoman said now was not the time to be easing travel measures. Joe Biden will take office at 12:00 (17:00 GMT) on Wednesday. However, much of the spotlight is on Trump's final moves, including presidential pardons. Security is intense in Washington DC ahead of the inauguration ceremony. Thousands of National Guard reserve soldiers have been deployed in the wake of the storming of the Capitol building by a pro-Trump mob on 6 January that left five people dead. The FBI had earlier warned of possible protests across the nation by right-wing extremists emboldened by the invasion. Joe Biden and his wife, Jill, are expected to travel to Washington from their home in Wilmington, Delaware, on Tuesd...

Pakistan set to launch 5G connectivity by 2022 after ‘loud, clear’ test call

Image
KARACHI: Pakistan is set to launch 5G mobile phone connectivity in the country by December 2022 following a successful trial call between Islamabad and Beijing earlier this month. Minister for Information Technology and Telecommunications Syed Aminul Haque on Sunday told Arab News that the test call on Nov. 4 had been “a wonderful experience. The voice was loud and clear, and the video (quality) was also wonderful. “I think December 2022 is the ideal date (to launch the 5G service) as it would take one to two years to improve infrastructure and increase optic fiber penetration across the country,” he said. Once implemented, it would place Pakistan among several emerging market countries – such as Azerbaijan, Bangladesh, Kazakhstan, India, and Sri Lanka – to launch the ultra-fast mobile internet service in the next two years. “It means that when the modern state-of-the-art technology comes to Pakistan, the country will make great economic progress,” Haque added. According to a...
