Abstract: It is possible to improve the spectral efficiency of multi-layer multiple input multiple output (MIMO) transmissions by estimating the magnitude parameter at the receiver side, rather signaling the magnitude parameter from the transmitter to the receiver. In long term evolution (LTE) networks, the user equipment (UE) may estimate the power allocation (Pa) parameter by executing a series of steps. For example, the UE may define a single unknown variable from a received downlink MIMO signal, extend the single unknown scalar variable to a multivariate signal model for multiple channels (N), convert the multivariate signal model to a MIMO configured signal model, and then obtain the Pa parameter from the MIMO configured multivariate signal model.

Abstract: A system and method manages call connections between mobile subscribers and an EP-based wireless telecommunications network through a wireless access point. Communications between the mobile subscribers and the IP-based wireless telecommunications network are initiated by a registration request. During the registration request various identifiers (IMSI, MAC address, IP Address, etc.) are communicated to the system. The system is arranged to log the identifiers and associate those identifiers with the entry point (e.g., the wireless access point) into the IP based wireless network. Call connections from the mobile subscribers are monitored for various throughput and call quality based metrics. Call handoffs between the IP-based wireless communications network and the cellular telephony network are managed by the system based on the monitored call quality and throughput metrics on a per-access point basis using the registered identifiers.

Abstract: Some embodiments provide an elastic architecture for providing a service in a computing system. To perform a service on the data messages, the service architecture uses a service node (SN) group that includes one primary service node (PSN) and zero or more secondary service nodes (SSNs). The service can be performed on a data message by either the PSN or one of the SSN. However, in addition to performing the service, the PSN also performs a load balancing operation that assesses the load on each service node (i.e., on the PSN or each SSN), and based on this assessment, has the data messages distributed to the service node(s) in its SN group. Based on the assessed load, the PSN in some embodiments also has one or more SSNs added to or removed from its SN group. To add or remove an SSN to or from the service node group, the PSN in some embodiments directs a set of controllers to add (e.g., instantiate or allocate) or remove the SSN to or from the SN group.
