Abstract: Using a first access node, a set of wireless devices are communicated with using a first frame configuration. The communication using the first frame configuration meets a first throughput threshold criteria for both a first and second subsets of the wireless devices A second frame configuration having a second ratio of uplink subframes to downlink subframes is selected. Based on the selection of the second frame configuration, a second access node is used concurrently with the first access node to communicate with the second subset of wireless devices using the second frame configuration.

Abstract: Systems and methods are described for providing multiple voice service modes to a wireless device using data packet transmission through a wireless network. Application requirements including a signal level threshold for a wireless device may be determined. Signal level information for the wireless device may be received and transmitted among various network nodes. The received signal level may be compared with the signal level threshold for the wireless device. The wireless device and the access node may communicate wirelessly to provide voice services to the wireless device application. Data transmission may be converted between a first mode and a second mode depending upon a relative position of the received signal level with respect to the signal level threshold. The second mode of data transmission may be used where the first mode of data transmission cannot because the second mode may consume less network resources.

Abstract: Systems and methods are described for determining structures for frequency bands. A signal area for an access node may be partitioned into a first partition and a second partition, wherein a first antenna is associated with the first partition and a second antenna is associated with the second partition. The first partition may be assigned a first frequency band and a third frequency band, and the second partition may be assigned a second frequency band and a fourth frequency band. A first frame structure may be selected for the first frequency band, a second frame structure may be selected for the second frequency band, a third frame structure may be selected for the third frequency band, and a fourth frame structure may be selected for the fourth frequency band, wherein the first frame structure differs from the third frame structure and the second frame structure differs from the fourth frame structure. Additionally, data may be communicated between the access node and a plurality of devices over each of the first, second, third, and fourth frequency bands using each respective frame structure selected for each frequency band.

Abstract: Contention-based random access operations are enhanced by enabling wireless devices to transmit a plurality of orthogonal preambles simultaneously to an access node, thereby increasing the probability of at least one preamble being heard by the access node, and minimizing the risk of preamble collision with another wireless device. Different classes of devices may be configured to transmit different numbers of preambles, depending on a priority level for that class, for purposes such as emergency communications, real-time applications, etc. Parameters including relationships between specific priority levels, device classes, application classes, quality of service, and number of preambles permitted, may be broadcast or otherwise communicated to wireless devices by the wireless network.

Abstract: Systems and methods are described for implicit information transfer. Neighboring access nodes may coordinate an Almost Blank Subframe (ABS) pattern for ABS transmissions. Implicit transmit symbols may be assigned to ABS′ of the ABS pattern. Traffic may be scheduled for a wireless device on at least one ABS of the ABS pattern. The neighboring access nodes may use the scheduled ABS to decode implicit information associated with the implicit transmit symbols.

Abstract: Systems and methods are described for improving capacity of voice services for data packet transmission through a wireless network. Application requirements including a data rate for a wireless device may be determined. An access node may determine available resources to transmit data as indicated by the application requirements. The wireless device and the access node may communicate data transmissions wirelessly for use by the wireless device application. Data transmission may be in a first mode or in a second mode depending whether there are sufficient available network resources for the determined data rate. The first and second transmission modes may be generated from a common input such as a wireless device user's voice; however, the second mode of data transmission may be converted in order to consume less network resources.

Abstract: Retransmission parameters are determined for a wireless device based on a desired retransmission success rate, that is, a probability that subsequent random access requests transmitted from the wireless device re-initiating a contention-based random access procedure with an access node will reach the access node. The retransmission parameters are determined based on at least a quality of service associated with the wireless device, a distance of the wireless device from the access node, and a cell load of the access node. The retransmission parameters include a retransmission power and a retransmission backoff window size. A product of the power and backoff window is scaled such that it can be equated with a retransmission success rate.

Abstract: Systems and methods for offloading traffic in a wireless communication system are provided. It can be determined at a network node that a performance parameter of an access node meets a performance threshold. A profile of a wireless device in communication with the access node can be determined where the profile comprises an acceptable offloading condition. A plurality of offloading mechanisms can be identified based on the performance parameter and the acceptable offloading condition. An estimated change in the performance parameter can be determined for each combination of one of the plurality of offloading mechanisms and the acceptable offloading condition. An offloading mechanism can be selected based on the estimated change in the performance parameter and the acceptable offloading condition. The wireless device can be instructed to establish communication with the wireless communication system using the selected offloading mechanism.
