Nov 20, 2013 PCell Functionality in LTE-Advanced. In LTE Rel-1o, the concept of Primary Cell ( PCell) and Secondary Cell (SCell) was introduced to support

즉, Pcell, Scell 모두 serving cell이 됩니다. UE를 위해 serve 한다는 개념입니다. Pcell 은 security에 관련된 기능을 수행하고, Scell은 오로지 data 전송에만 주력합니다. pCell isn’t just LTE. Each pCell supports a different protocol to each device in the same spectrum concurrently. pWave Minis support multiple current and future protocols at once. For example, the same pWave Mini deployment will concurrently support 5G-class LTE devices and Fixed Wireless CPEs in the same spectrum.

Pcell and scell

This cell is called PCell. As the name implies, PCell most "main" cell in MCG. The PCell under MCG and the SCell under MCG are united together by Carrier Aggregation (CA) technology. (see figure shown above) In CA the UE is camped to only one cell (PCell) called the Primary serving cell, served by the Primary component carrier (PCC). The other component carriers are all referred to as Secondary component carriers (SCC), served by the Secondary serving cells (SCell). During Handover, if the same SCell is in use in the target PCell (i.e., SCell is not released during Handover), the SCell in the target Cell in initially in the deactivated state. Activation/Deactivation of SCells will be discussed in detail in further posts.

pCell isn’t just LTE. Each pCell supports a different protocol to each device in the same spectrum concurrently. pWave Minis support multiple current and future protocols at once. For example, the same pWave Mini deployment will concurrently support 5G-class LTE devices and Fixed Wireless CPEs in the same spectrum.

At least, it was confusing to me. In stead of describing in general terms, just giving you a couple of example cases would clarify a lot.

A method for controlling downlink HARQ timing according to an embodiment of the present invention comprises the steps of: configuring, by a base station, different duplex modes for a PCell and an SCell and transmitting the configuration information to a terminal; transmitting, by the base Version: V AT Command Reference Guide 2.0 Date: 2018-07-12 LTE Module Series ME3630 Website: www.gosuncnwelink.com E-mail: welink@gosuncn.com When CA is conducted, a User Equipment (UE) will firstly select a Primary Serving Cell (PCell) for mobility support and then add Secondary Serving Cells (SCell) for higher experienced data rate. When and how to add/remove SCell is a very important issue, especially in heterogeneous network where the radio condition of different Component Carriers (CC) are totally different.

Cell towers as we know them today can be visualized as giant umbrella tops.

carriers are compared every 200ms. If it is not time to . In 5G NR, for the procedures such as handover to a stronger cells or adding a new Carrier Component (CC) in the case of Carrier Aggression, it is required to measure the serving cell and neighbor cell signal strength or signal quality matrix i.e. RSRP or RSRQ. 設定したSCell（PUCCH-SCell）のいずれかに関連付けられてグルーピングされる．UEは，設定されたグループごとに，各CCのUCIをPCell またはPUCCH-SCellで送信する．これにより，スモールセルに位置するUEに対し，PCellはマクロセルに設定しつつ，SCellとして設定さ A: At this time, PCell and SCell are essentially different carrier frequencies covering the same geographic area (e.g., a given 120 degree cell).

Now, there is a. 3. Multiple Carrier with no Simultaneous PUCCH and PUSCH. concept of Timing Advance Group (TAG).

The SCell(s) transmit PDCCH and PDSCH (downlink control and data) and receives the PUSCH (uplink data) .SCells may optionally not use the PDCCH if a feature called cross-carrier scheduling is supported by both the UE and the network; cross-carrier scheduling is a process where scheduling for all the bearers are managed by one of them, namely the PCell bearer .This reserves the SCell traffic
