A Wi-Fi radio transitions to deep sleep mode from active mode while a Bluetooth radio remains active. An active Wi-Fi connection to the access point can be maintained by the station while in deep sleep mode as needed to prevent being disassociated. Responsive to the indication of data packets waiting at the access point, sent over the Bluetooth radio, the Wi-Fi radio at the station can be transitioned from the deep sleep mode to the active mode. A notification of active mode is sent to the access point currently associated with the Wi-Fi radio so that packets can be forwarded.

  • Patent number: 10244516
    Abstract: In order to reduce the HS-SCCH overhead, a fixed time allocation approach could be used. In that case, the scheduling time of each VoIP user is semi-static and thus there is no need to transmit e.g. HS-SCCH toward the UE for the initial transmissions, if the UE knows when to receive data on the HS-DSCH and what transport format is used. There are at least two ways of implementing this: 1) HS-SCCH/E-DPCCH signalling to indicate parameters of a first transmission, with subsequent transmissions using the same parameters (and HS-SCCH/E-DPCCH always sent when changes needed), or 2) fixed allocation, RRC signalling used to allocate users and tell the default transport parameters.

    Abstract: A low-complexity Radio Resource Allocation method (100,200) efficiently assigns frequency resources, such as a set of contiguous subcarriers, to Mobile Terminals in SC-FDMA uplink systems. The inventive method initially finds the resource allocation that leads to maximum efficiency in terms of transmitted data rate, without considering any resource adjacency constraint. Subsequently, the method iteratively redefines the resource allocation in order to find a resource allocation that is in accordance with resource allocation adjacency required by the SC-FDMA multiple access scheme.

  • Patent number: 9955480
    Abstract: A low-complexity, efficient Radio Resource Allocation method performed by a base station of a wireless communication network allocates a first plurality of frequency resources among a second plurality of requesting mobile terminals. Each mobile terminal employs a service such that two or more services are represented in the second plurality. The RRA method satisfies all of an exclusivity constraint that each frequency resource is allocated to only one mobile terminal, an adjacency constraint that all frequency resources allocated to any given mobile terminal are contiguous in a frequency domain, and a minimum service requirement constraint that a predetermined number of the mobile terminals employing each service be granted a required data rate. The RRA method comprises two phases: Unconstrained Maximization and Reallocation.

    Abstract: Where first and second reference signals for a first and second communication system, respectively, are transmitted, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS for LTE-A, last half symbols in a time direction of a resource unit RB/Sub-frame defined in a frequency-time domain are used, and the CSI-RS is allocated in a position up to the last two symbols or in the last symbol, or the like, of a particular RB/Sub-frame and transmitted when a reference signal 4RS for LTE is transmitted to a reception apparatus in addition to transmitting CSI-RS for LTE-A. The reception apparatus receives CSI-RS allocated in the last half symbol of RB/Sub-frame based on CSI-RS allocation information, measures channel quality by using this CSI-RS, and transmits and reports feedback information.
