An apparatus is configured to transmit a preconfigured number of transmissions of a first data with hybrid automatic repeat requests consecutively without waiting between the transmissions for response to any of the requests, wherein the preconfigured number is an integer and greater than one.

Adapting hybrid automatic repeat requests

In a cell where messages having a message type are sent without knowledge of radio frequency conditions for individual ones of user equipment within the cell, measured radio frequency conditions are accessed of multiple user equipment within the cell. Based on the measured radio frequency conditions, a minimum control channel coding rate is determined for a control channel for messages having the message type. Subsequent to a determination of the minimum control channel coding rate, transmission is caused toward all user equipment in the cell of the messages having the message type using the determined minimum control channel coding rate for the control channel. Methods, apparatus, computer programs, and program products are disclosed. The methods may be performed by a base station, self-organizing network server, or other apparatus.

Dynamic resource adaptation

Performing power control by determining a maximum required signal-to-interference plus noise ratio for a nominal packet size of a received data signal, wherein the maximum required signal-to-interference plus noise ratio corresponds to a quantity of physical resource blocks used for the nominal packet size of the data signal. A received signal-to-interference plus noise ratio of the received data signal is compared with the maximum required signal-to-interference plus noise ratio. In response to the received signal-to-interference plus noise ratio exceeding the maximum required signal-to-interference plus noise ratio, power control is performed for the data signal to reduce the received signal-to-interference plus noise ratio.

Performing power control based on nominal packet size

A method, system, and base station for deterministically selecting a downlink transmission mode and rank in a Long Term Evolution (LTE) configured wireless communication system. The Transmission Mode Selection (TMS) utility receives from a wireless device a request for downlink physical downlink shared channel (PDSCH) service using a particular transmission mode and specific rank. The TMS utility determines an estimate of the throughput corresponding to the request. In addition, the TMS utility obtains throughput estimates of other distinct pairings of transmission mode and rank to compare with the throughput estimate corresponding to the request. The TMS utility utilizes device feedback information and HARQ error information that are already existing/available in order to determine the best transmission mode and rank pair, according to the best Error-Adjusted-Throughput.

A method and apparatus for controlling interference in a wireless communication system includes a first step of performinga handoff measurement of a signal parameter for a current site and for nearby sites, and performinga comparison of the signal parameters to select the nearby site having the strongest signal parameter. A next stepincludes defining a target maximum allowable noise rise for the selected nearby site. A next stepincludes calculating an upper bound for at least one operating parameter in the current site. A next stepincludes determining whether a maximum for the at least one operating parameter exceedsthe upper bound. A next stepincludes constraining the at least one operating parameter to no more than the upper bound if the maximum for the at least one operating parameter exceeds the upper bound.

A method and system for adaptively allocating shared communication resources in response to an emergency event are disclosed herein. In one embodiment, the method includes identifying a response zoneassociated with an emergency event and dispatching emergency responders, andhaving communication devices-to the response zone. The dispatching procedure includes adjusting access of the emergency responder communication devices to shared communications resources. Adjusting access to shared communication resources includes identifying one or more of the emergency responder communication devices to be dispatched to the identified response zone and specifying a quality of service (QoS) priority level of at least one of the identified emergency responder communication devices. Adjusting access to shared communication resources further includes specifying a QoS priority level for communication devices located within the identified response zone.

Emergency dispatch management and prioritization of communication resources

This method () adaptively sends control messages and a predetermined number of fast repeats of the control messages on the traffic channel of a mobile communication system. For a control message which has already been lost (), the system sends the control message again with a first number of fast repeats () if the traffic channel is operating at a full rate; and the system sends the control message with a second number of fast repeats if the traffic channel is operating at a subrate. The number of fast repeats is selectable. If the control message has not been previously sent and the traffic channel is operating at a subrate (), the system will send the control message with a third number of fast repeats ().

An RF power fairness method () receives a request for supplemental channel resources (). If sufficient supplemental channel resources (time slots and data rates) are not available, the original request is modified (). If there is multiple call activity on the supplemental channel, RF power is calculated for each of the simultaneous calls on the shared channel (). If successful time slots and data rates are found, a grant message is returned from the time slot manager () to the base station (). If insufficient time slots and data rate power are determined, a deny request message is transmitted to the base station ().

Fairness method for supplemental channel resources

A CDMA system according to an embodiment of the invention employs a technique for power optimized user loading that obtains a desired allocation of different radio configuration calls. The technique takes advantage of the relatively low power requirements of RC3 calls for low load conditions, while increasing the number of RC4 calls for high load conditions. As the load increases, the system determines a target combination of RC3 and RC4 calls based upon the current average power per link measurements for RC3 and RC4 calls, and based upon the power limitations of the system. The technique strives to maximize the capacity of the system while maintaining operation below the overall power limit.

System and method for managing CDMA communication system capacity using power-based metrics

A CDMA system according to an embodiment of the invention employs a technique for power optimized user loading that obtains a desired allocation of different radio configuration calls. The technique takes advantage of the relatively low power requirements of RC3 calls for low load conditions, while increasing the number of RC4 calls for high load conditions. As the load increases, the percentage of RC4 calls increases while the percentage of RC3 calls decreases. The technique strives to minimize overall power consumption in the system for all call load conditions, by maximizing the number of RC3 calls at any given time while keeping Walsh code resources available for both new calls and hand-in traffic.

A method () schedules the utilization of the supplemental channel of a base station transceiver (-). This scheduling includes time slot assignment as well as data transfer rate per time slot. One method simply selects the next time slot with a maximum rate for the primary base station transceiver (). The method then selects the same time slot for each of the secondary links with the secondary base stations (). The data is then simply sent to each of the BTSs (-) for transmission to the mobile station (). In another alternative, a request is made for a supplemental channel usage for the primary link (). Then secondary links are selected for transmission to the mobile station () only if they provide additional diversity gain () and resources are available at the secondary link BTSs.
