International Classification:

H04B007/216

US Classification:

370335, 4554221

Abstract:

Disclosed is a method of integrating voice and data services onto a same frequency channel using available transmit power information to determine data rates, wherein the available transmit power information indicates an amount of transmit power available for future data transmissions over one or more data channels. In a “distributed” embodiment, a transmitter or base station transmits, via a forward link, an available power message to a receiver or mobile-telephone indicating an amount of available transmit power at some future time t+z. The mobile-telephone performs signal-to-interference measurements corresponding to the received forward link and received interference, and uses such signal-to-interference measurements and the available power message to determine a data rate that can be supported by the mobile-telephone. Preferably, the determined data rate corresponds to a maximum data rate at which a minimum level of quality of service can be achieved at the mobile-telephone. In a “centralized” embodiment, the mobile-telephone transmits the signal-to-interference measurements to the base station, and the base station determines the data rate based on the available transmit power at future time t+z.

International Classification:

H04B001/38
H04M001/00

US Classification:

4555621, 4555757, 4555501, 455101

Abstract:

A communication system's transmit configuration is reconfigured based on mobile station associated conditions such as the capability of the mobile receiver, carrier to interference or signal to noise ratios, and the degree of mobility associated with the mobile station. As a result, the transmit configuration is optimized for the conditions associated with a particular mobile receiver. In one embodiment, the transmit configuration may be selected to operate in configurations such as a single transmit antenna configuration, a space time spreading configuration, a selective transmit diversity, and a multi-output and multi-input configuration.

International Classification:

H04J011/00

US Classification:

370209, 370331, 370335, 455442, 455444

Abstract:

The code space associated with the communication system is divided into at least two subspaces where each subspace is assigned to a different mode of operation. In one mode, such as a voice mode, each user is given full time access to a portion of the subspace associated with that mode of operation. In a second mode, such as a data mode, each user uses the entire subspace associated with that mode on a time shared basis. Additionally, in-sector handoffs from one Walsh code to another are used to more efficiently distribute the code space.

International Classification:

H04Q007/20

US Classification:

455/562000, 455/450000, 455/453000, 455/507000

Abstract:

A method for increasing the capacity of a communication network by assigning subscribers of the communication network to individual antennas of an antenna array and allowing the antenna array to convey information to the assigned subscribers under the control of a scheduling algorithm. Antennas—under the control of the scheduling algorithm—in the antenna array are thus able to convey information to different subscribers at different times. The scheduling algorithm determines when to convey information to an assigned subscriber based on channel condition information it receives from the subscribers. The scheduling algorithm also uses the channel condition information to assign certain subscribers to certain antennas.

Abstract:

A service group based dynamic optimization of WWAN and WLAN aggregation in user equipment (UE) is described. The UE has a first radio access technology (RAT) interface associated with a Wireless Wide Area Network (WWAN) based interface that is served by a corresponding base station (BS), and a second RAT interface associated with a Wireless Local Area Network (WLAN) based interface that is served by an Access Point (AP), wherein, for downlink communications, the first and second RAT interfaces are aggregated. Each UE belongs to at least one service group, wherein the UE performs service group based dynamic optimization of WWAN and WLAN aggregation, with flow split ratios and resource allocation between RAT interfaces being jointly optimized for each service group and each RAT interface.

International Classification:

H04W 28/08

Abstract:

Any one of the following dual connectivity attributes is assigned to a group profile of each service group: (1) macro cell only (serving both data/control planes via a macro cell base station.), (2) small cell only (serving data/control planes via a small cell base station), (3) dual connectivity enabled-A (serving data plane of UEs via a small cell base station, and serving control plane via a macro cell base station), and (4) dual connectivity enabled-B (serving data plane via both a macro cell base station and a small cell base station, and serving control plane via a macro cell base station), wherein the RAN controller calculates and sets the optimal splitting between the macro cell base station and the small cell base station dynamically, such that desired load balancing is achieved.

Abstract:

Base stations as well as Radio Access Network (RAN) controllers have embedded communication agents that are responsible from control messaging between these entities that enable creation and management of RAN Slices. At a given time, it is possible that multiple active RAN slices co-exist on the same base station, where each RAN slice may run its own scheduler, its own admission control and have its own handoff management parameter values.
