Problems solved by technology

This increases complexity and requires higher capability hardware
[0013] Another disadvantage of FCC is that it will substantially increase the block error rate (BLER) of the target UE as FCC
This can especially cause problems for UEs with relatively high QoS requirements
At this point, the FCC scheme cannot be exploited aggressively, some load margin still needs to be preserved

Embodiment Construction

[0047] Hereinafter, embodiments of the present disclosure will be described based on the drawings. In the following description, some specific embodiments are for illustrative purposes only, and should not be construed as any limitation to the present disclosure, but as examples thereof. Descriptions of conventional structures or constructions will be omitted so as not to obscure the understanding of the present disclosure.

[0048] To alleviate the problems with the FCC approach (i.e., high demand for fast RoT measurements that may not be supported by current mainstream Node B hardware), proposed in U.S. Provisional Application No. 61 / 555,669, filed November 4, 2011 The Slow Congestion Control (SCC) scheme, the entire contents of which are incorporated herein by reference. In the SCC scheme, congestion control is based on radio frame-based RoT measurements (eg, a sampling rate of 10 ms). The basic idea is that when a newly received RoT measurement is above a configurable SC...

Abstract

The present disclosure relates to uplink congestion control schemes. In one embodiment, an uplink congestion control method is provided, comprising the following steps: determining whether the congestion status of the serving cell has changed based on thermal noise rise RoT measurement; sending signaling indicating the change of the congestion status to a set of user equipment UEs and performing uplink congestion control based on the RoT measurement and utilizing at least one UE in the set of UEs at least based on the signalling-based Enhanced Transmission Format Combination E-TFC reselection.

Description

technical field [0001] The present disclosure relates to a wireless communication system, and more particularly, to an uplink congestion control scheme. Background technique [0002] In the uplink, the common radio resource shared by user terminals is the total amount of tolerable interference, which is defined as the average interference over all receive (Rx) antennas. A relative measure of total interference is lift over thermal (RoT), ie total interference relative to thermal noise. [0003] Uplink load control adjusts the load headroom of the cell to steer the measured RoT towards the target RoT. Typically, RoT measurements are available every radio frame (eg, 10 ms). The uplink scheduler allocates the available uplink (UL) load to the scheduled UEs that require higher bit rate, and reduces the granted uplink bit rate of some scheduled UEs when the system is overloaded . Large RoT oscillations (either above or below RoT target), and the RoT summit lasts long before ...
