20110076969 | Gating Control Loop - The present invention is about tuning the gating scheme according to the performance of the application used. This can mean that in some situations gating is not used at all while in other occasions gating is used where the cycle length, burst length, number of preambles and offset are adjusted. The performance is monitored and the gating is increased or decreased depending on the results of the monitoring and demands of the application. Furthermore, the gating scheme adapts to the current performance and is chosen to optimize performance in terms of system capacity. The monitoring also takes into account which of the gating cycles that needs to be changed. The algorithm is self tuning/configuring meaning that it will control the gating scheme to find and keep an optimal level for the used application. The method may be implemented both in a mobile terminal (UE) and in an infrastructure node (BS) and executed by instruction sets belonging to a computer program. | 03-31-2011 |
20110110245 | Code Assignment in HS-SCCH Less Operation Mode - In a method and a system a good spread of users per code is obtained by providing a value related to the current load for each code in the system. The estimated load value can be used by the network to assign the HS-PDSCH code for users in HS-SCCH less operation, and may also be used in the dynamic transmission process, i.e. which codes are to be used by which user during this and future TTIs. If one code is over a given utilization threshold, where the threshold is set in order to avoid code blocking of VoIP users, enough users can be re-assigned to a different code. In the case that all of the current codes used in the HS-SCCH less operation model are over the utilization threshold, yet another code can be made available for HS-SCCH less operation. | 05-12-2011 |
