Universal Mobile Telecommunications System (UMTS); Continuous connectivity for packet data users

inactive
Organization: ETSI
Publication Date: 1 April 2017
Status: inactive
Page Count: 145
scope:

The present document summarizes the work done under the WI "Continuous Connectivity for Packet Data Users" defined in [1] by listing technical concepts addressing the objectives of the work item (see below), analysing these technical concepts and selecting the best solution (which might be a combination of technical concepts).

"The objective of this work item is to reduce the uplink noise rise from physical control channels of packet data users, e.g. for users which have temporarily no data transmission.

This is intended to significantly increase the number of packet data users (i.e. HS-DSCH/E-DCH users without UL DPDCH) in the UMTS FDD system that can stay in CELL_DCH state over a long time period, without degrading cell throughput, and that can restart transmission after a period of inactivity with a much shorter delay (<50ms) than would be necessary for reestablishment of a new connection

The objective covers also schemes which could allow improving the achievable UL capacity for VoIP users with its inherent periodic transmission through reducing the overhead of the control channels.

Mobility and downlink transmission should not be impacted for these users."

The present document provides the base for the following preparation of change requests to the corresponding RAN specifications.
