20100111069 | SYSTEM AND METHOD OF DOWNLINKING DATA TO AN UNSYNCHRONIZED USER EQUIPMENT IN A TELECOMMUNICATIONS NETWORK - A system, method and node of downlinking transmissions to an unsynchronized UE in a telecommunications network. The method begins by a node in the network requesting synchronization of the UE with the network. A first transmission of data is sent from the node to the UE prior to synchronization of the UE. The UE then synchronizes with the network by the UE performing a Random Access procedure with the node, thereby triggering a time alignment command from the node to the UE to synchronize the UE with the network. A second transmission of data is then sent from the node to the UE after the UE is synchronized. A response feedback message is sent to the node from the UE. The message is a cumulative feedback message of the first transmission of data and the second transmission of data. Thus, data may be transmitted prior to synchronization of the UE. | 05-06-2010 |

20110053602 | REPEATER GAIN CONTROL METHOD AND APPARATUS - This document proposes soft activation and inactivation of (network) repeaters that are, for example, activated on an as-needed basis.

Likewise, with soft inactivation, repeater gain ramps downward at a controlled rate. Soft activation/inactivation results in more gradual changes in the interference contribution of the repeater, thereby improving the performance of interference-compensating radio receivers operating in proximity to the repeater. | 03-03-2011 |
20110269393 | Method and Apparatus for Uplink Scheduling using Relays - In one or more embodiments, the present invention provides a method and apparatus for “early” triggering of a BSR in a relay node.

Of course, that example is non-limiting. More broadly, in at least one embodiment, the present invention provides for triggering a BSR in the relay node right after learning that there is at least one UE connected to the relay node that wants to transmit UL data.

In one embodiment, a (base station) method of AQM for the uplink includes estimating at least one of a transmit buffer size and a transmit buffer queuing delay for a UE, and selectively dropping or congestion-marking packets received at the base station from the UE. The selective dropping or marking is based on the estimated transmit buffer size and/or the estimated transmit buffer queuing delay. | 02-16-2012 |

The terminal determines a first set of time periods during which available access resources, permitted for use by the access class of the terminal, may be used by the terminal to access the radio network. The first time period set is different from other sets of time periods permitted for use by other access classes. The terminal communicates using the available access resources during the first set of time periods to reduce network load. | 11-08-2012 |
