What is ue in lte

The signal measurements may be made by the UE or the eNode B. Hybrid positioning using multiple methods from the list of positioning methods above is also supported. The MME receives a request for some location service associated with a particular target UE from another entity e. In the case of a location service requested by an entity other than the MME e.

Advertise with us. Figure 5 shows an example of dynamic IP address allocation. Figure 5. IP address allocation and format. An eNB is responsible for allocating radio resources to UEs on uplink and downlink. Many UEs stay connected to an eNB at the same time. Figure 7. Figure 8. Thanks again for your kind comment. In fact, there is no such interface. Just a comment on fig. Great doc here! I loved the simplicity and preciseness here. Excellent job!

It is brief and clear to the point. I like the diagrams -very intuitive with necessary info. Netmanias USA : 36th Ave. All rights reserved. English Korean About Us. HFR, Inc. Download PDF File. Table of Contents 1. Closing and References 3.

But the size increase by FGI was minor. The real explosion of the size came out with the support of Carrier Aggregation. However, as higher carrier aggregation i.

As of Release 13, we have almost several hundreds possible band combinations. The current several hundred different combination is not with 3CC CA. The root cause was a kind of message buffer overflow, meaning that the size of the incoming signaling message hit the size of memory allocated to store the message. What would be the solution for handling this kind of too over-sized message? One brutal solution would be to reserve super-large message buffer size and ensure that your ASN decoder works properly for such a super large tree structure.

Another possible solution seemingly better solution would be to limit the scope of the information that UE report in UE Capability Information message. The Enquiry item is configured very simple. If the UE support full capability of Rel 13 and a lot of band combination.. With this, Network can force UE to send the only capability information that are necessary to the current Network. As can be seen in the table below, the different LTE categories have a wide range in the supported parameters and performance.

It is also worth noting that UE class 1 does not offer the performance offered by that of the highest performance HSPA category. Additionally all LTE UE categories are capable of receiving transmissions from up to four antenna ports. Note: Maximum datarates shown are for 20 MHz of channel bandwidth.

Categories 6 and above include datarates from combining multiple 20 MHz channels using Carrier Aggregation. Maximum datarates will be lower if less bandwidth is utilized. Note: These are L1 transport data rates not including the different protocol layers overhead. Depending on cell BW, cell load, network configuration, the performance of the UE used, propagation conditions, etc.
