Various embodiments provide for the management of wireless resources, which can reduce call blocking by allowing high priority services, under suitable conditions, to use resources allocated to low priority services. Thus high priority services can pre-empt the usage of wireless resources by low priority services. This has the advantage of reducing call blocking for high priority calls, while permitting low priority calls to have more access to radio resources than conventional systems with the same call blocking rate. Thus a base station can implement a preemption mechanism that would reclaim Walsh Code and Forward Power resources from an active Supplemental Channel (SCH) burst in order to accommodate incoming Fundamental Channel (FCH) requests.

Managing wireless resources

A method and system for achieving a link budget improvement in a diverse OFDM radio system by addressing the timing misalignment issue that can occur due to the differences in propagation time in signals between mobile stations and Radio Access Nodes. Timing misalignment is shared or split between the primary path to a primary Radio Access Node and a diverse path to a diverse Radio Access Node. The relative timing offsets between mobile stations are adjusted, the mobile stations are grouped into zones using a variety of different grouping techniques, and the transmission for each mobile station is scheduled, using one or more of a variety of scheduling techniques.

Transmitter time adjustments for groups of receivers

A method and system for coordinated interference suppression in a communication system. The communication system implements at least a first radio access technology via a first base station and a second radio access technology via a second base station. The first and second radio access technologies differ from one another. Information relating to an interference signal received at the first base station via the first radio access technology is received at the second base station from a first device associated with the first base station. At a second device associated with the second base station, an interfering user equipment accessing the second base station via the second radio access technology is identified. The identification is based on the information received from the first device associated with the first base station. Interference caused by the identified interfering user equipment is suppressed by the second base station.

Inter-radio access technology interference coordination for multi-standard radio access networks

A method and mechanism to reduce the energy consumption of a single-carrier wireless transmission system such as a base station or a subnet of multiple base stations in relation to the loading of the system. Energy savings may be achieved by withholding the transmission of the system over some time slots, decreasing the available frequencies for user traffic transmission, dynamically adjusting the system to a lower bandwidth, or a combination of these techniques in proportion to the system transmission load at a given time. The lower the system load, the more transmission resources may be withheld or reduced, and, hence, the more savings in energy consumption. Energy savings may be most prominent during periods of low traffic loading of the single carrier-based wireless transmission system.

Interference caused by the identified interfering user equipment is suppressed by the second base station.

Method and system for diversity using orthogonal frequency/division multiplexing

To provide space division multiple access in a wireless network, plural beams are transmitted within a cell segment. Different information sets are sent in the corresponding plural beams, where one or more of the information sets are detectable by a mobile station depending upon a location of the mobile station in the cell segment. An indication responsive to which of the different information sets is detected by the mobile station is received, and beam selection from among the plural beams is performed according to the received indication.

Providing space division multiple access in a wireless network

A Packet Control Function (PCF) may not have enough knowledge about packet data arriving on a bearer path via a Packet Data Serving Node (PDSN) to appropriately decide how best to handle the packet data. Thus, the PDSN may provide bearer-specific information by encapsulating the packet data within the payload of a Generic Routing Encapsulation (GRE) frame, and for a requested feature, setting a protocol-type field in the header of the GRE frame indicating that the packet includes an attribute field, and adding an attribute field to the payload of the GRE packet to provide attribute data corresponding to the requested feature. The PCF may send an A-11 request to the PDSN indicating which features the PDSN is requested to enable. For example, for short data indication, the PCF may request the PDSN add to the GRE frame an attribute field containing attribute data indicating when a Short Data Burst is suitable.

The invention provides for the management of wireless resources, which can reduce call blocking by allowing high priority services, under suitable conditions, to use resources allocated to low priority services. Thus high priority services can pre-empt the usage of wireless resources by low priority services. This has the advantage of reducing call blocking for high priority calls, while permitting low priority calls to have more access to radio resources than conventional systems with the same call blocking rate. Thus a base station can implement a preemption mechanism that would reclaim Walsh Code and Forward Power resources from an active Supplemental Channel (SCH) burst in order to accommodate incoming Fundamental Channel (FCH) requests.

The Packet Control Function (PCF) has limited knowledge about the nature of the packet data arriving on a bearer path connected via the Packet Data Serving Node (PDSN), and cannot make an intelligent decision on its own as to how best to handle the packet data. Thus, the PDSN provides bearer-specific information by classifying the priority of received packet data; encapsulating the packet data within the payload of a Generic Routing Encapsulation (GRE) frame; and for high priority packet data i) setting a protocol type field in the header of the GRE frame indicating said packet includes an attribute field; and ii) adding an attribute field to the payload of the GRE packet which provides an indication of said high priority data. Furthermore, the PCF can send an A-request to the PDSN indicating the features that the PCF is requesting the PDSN enable. For example, for a short data indication, the PCF would request the PDSN enable adding the attribute field to the GRE frame when an Short Data Burst (SDB) is suitable.

The present invention provides a method and apparatus for improving wireless communication network performance and efficiency, based on detecting the occurrence of grant loss in relation to the transmission of scheduling grants to mobile terminals over a downlink control channel. Grant loss detection is based on detecting erasure events corresponding to the transmitted scheduling grants, and the incidence of grant loss with respect to a given mobile terminal can be tracked and used to compensate the control value(s) used for link adaptation of the downlink control channel, with respect to that terminal. Additionally, or alternatively, when a given grant is determined to be lost, a new grant is sent and the HARQ redundancy version is reset for the newly scheduled transmission.
