- a UE gets access to the network by searching for DL synchronization channel first. After it is synchronized on downlink, it could get essential system information from a master information block (MIB) and a system information block (SIB) . It could also get synchronized with network on uplink by going through a random access channel (RACH) procedure. After synchronization on both links are completed, it could set up connection with the network at different levels and start to communicate with the network.

- an area covered by a base station is denoted as a cell and has a cell ID associated with it, and if multiple carriers are also supported in this case, each carrier could be denoted as a separate cell as well and have separate cell ID associated with each of the carrier (as each carrier is separate in frequency domain) .
- Conventional cellular system provides good solution for wireless communication such that frequency reuse, interference mitigation can be utilized. However, it has some drawbacks that need to be overcome. One of them is the handover (HO) , namely, when UE moves from one cell to the other, it needs HO procedure to hand over the UE from one cell to the other, which may take longer time and incur more latency.
- HO handover
- UE centric no cell (UCNC) concept is considered by some companies but most companies are not clear about its benefits. In the end, some of the mechanism on UCNC was specified but there still exists ambiguity and gap for a complete solution. For example, in Rel-18 low-layer trigger mobility (LTM) is introduced for node switch at lower layer which will reduce the HO latency. However, overall cell concept is still used.
- LTM low-layer trigger mobility
- the system could be more hybrid and comprise different types of TP nodes including both base station and TRP (either a remote antenna head or a simple transmit/receive point) .
- the function of each TP could be different, some for coverage enhancement and some for capacity enhancement, the coverage of each TP could be overlapped as well.
- More component carriers (CC) could also be used to expand the frequency bandwidth. From the energy saving perspective, certain TP could be turn on/off and such behaviors could be quite dynamic to save both network and UE energy without sacrificing the performance. More latency sensitive application also requires more smooth and continuous service even when UE moves around in the system, which makes the conventional HO difficult to handle.

- the link between DL and UL may also be transmitted to different TRPs, different Macro BS, or different small stations.
- one UE in the middle, e.g., UE#2 can receive and transmit the DL/UL PDSCH/PUSCH through the small station near it (e.g., TP#2) . It could also transmit the uplink signals to the small station (e.g., TP#3) on the right.

- the service from other TRPs e.g., the TP#3 and TP#6
- the UE#3 and UE#4 could fully fill the need of UEs (e.g., the UE#3 and UE#4) .
- Another kind of level is sleep level, which means that the BS could fall asleep for a while, like several minutes.
- the BS may find that the Service at the moment can full-fill the need of the UEs (e.g., UE#1) .
- the two TRPs TP#4 and TP#5 in the right hand of the figure are powered off, as the control channel can be done by the Macro BS (TP#6) , and the UEs in the field is with small numbers of activated, so Two of all TRPs can choose to power-off for power saving.
- a network node when a network node enters a power saving mode, it causes the change of communication between the UE and the network side.
- the change of network nodes is a complicated procedure in conventional communication system.
- An anchor carrier may be set up to carry specific signaling (e.g., control signaling) or provide specific services (e.g., recovering connection from interrupting) .
- an anchor carrier may be a low-frequency carrier, such as 2.6GHz, so that the anchor carrier generally has good coverage. Therefore, the anchor carrier can guarantee the reliable transmission of signaling, and UE may always access the anchor carrier.
- An initial access carrier may be a carrier to which the UE initially accesses (or initial attaches) .
- a serving carrier may be set up to carry specific signaling (e.g., data) .

- the anchor carrier may be the most guaranteed carrier, the UE can access the anchor carrier first when it initially accesses, or wakes up from sleep mode, or recovers from interruption. The UE may then be configured by the network side to other carriers for further connection after the connection is established with the anchor CC. This avoids reconnecting in a huge number of carriers, which may take a long time. This is not limited to this application.

- CSI-RS and other RS i.e. DMRS of PDCCH, DMRS of PDSCH, and so on for downlink, and SRS, DMRS for PUCCH, DMRS for PUSCH, and so on for uplink
- the UE should know all the information about the signals will send. Apart from this, even some report priority or measurement priority can also be sent to UE based on the UE capability report or the network side preference.
- the UE can assume that it has enough information about the serving CC or related signals. This is due to the fact that the SSB measurement is considered for idle or inactive type measurement. Like the UE just wakes up from sleep, the UE has no sufficient information and can only do the SSB detection and the RSRP measurement. But if it is the connected type for the UE, it means the UE has efficient information from the network side, and the measurement can be large bandwidth by using the CSI-RS or other related reference signals (RS) for downlink or uplink physical layers. So in the activated type, the UE can measure the Channel more accurate, and has more ways to reduce the measurement, because it can relate to more other channels and larger BW.
