    摘要: A system and method for enhancing the performance in heterogeneous wireless access networks employing a distributed antenna system is disclosed. A control unit comprises a distributed antenna system management server which collects load information from each of the carriers. The control unit further comprises a power management decision engine which determines the optimal downlink transmission power level for the carriers based on the collected load information and a set of parameters related to the power for the carriers. Power levels may decrease to baseline parameters when the load on carriers decreases.

    摘要: A system and method for dynamically optimizing the transmission power levels for downlink voice and data signal transmitted from a base station to user equipment is disclosed. The user equipment measures the strength and quality of the downlink signal, and transmits this downlink signal information to a control unit. The control unit analyzes the downlink information and employs an adaptive self-learning traffic algorithm which determines optimized power levels for the downlink signals. The control unit may optimize only one carrier signal or a subset of the multi-carrier signals in a preferred embodiment. The values of the optimized power levels are sent to the base station which then increases or decreases the downlink transmission power of one or more carrier signals based on this level. As a result, the area associated with dead spots is reduced and the quality of the downlink signals is enhanced.

    摘要: A method selects mobile station candidates for use with virtual multiple-input multiple-output (“V-MIMO”) in a communication system. The communication system includes at least one base station and a plurality of mobile stations. At least one downlink metric is determined for a first mobile station. The at least one downlink metric is used to determine eligibility for uplink V-MIMO candidate list selection. Responsive to determining that the first mobile station is eligible for uplink V-MIMO candidate list selection, the first mobile station is paired with a second mobile station eligible for uplink V-MIMO candidate list selection.

    摘要: Systems, methods and apparatuses of determining whether to admit the mobile device to the hot spot are disclosed. One method includes establishing communication between a hot spot and a mobile device, determining a first level of communication directly between the mobile device and a cellular network, determining a second level of communication between the mobile device and the cellular network through the hot spot, and identifying a fraction of other mobile devices having a level of communication directly with the cellular network. The method further includes determining whether to admit the mobile device to the hot spot based on a comparison of the first level of communication with the second level of communication, and the fraction of other mobile devices having a level of communication directly with the cellular network that is either better or worse than the first level of communication.
