摘要： Backhaul data may be communicated between an access node and a relay wireless device, wherein the relay wireless device serves as backhaul for a plurality of end-user wireless devices and a set of the plurality of the end-user wireless devices comprise a quality of service metric that meets a quality of service criteria. Wireless resources may be scheduled for the relay wireless device using semi-persistent scheduling such that wireless resources are pre-allocated for the relay wireless device based on a periodicity. And data may be transmitted according to the semi-persistent scheduling from the access node to the relay wireless device based on the periodicity, wherein data for the set of end-user wireless devices that is received at the access node between transmissions for the semi-persistent scheduling is queued such that it is transmitted to the relay wireless device at a next transmission for the semi-persistent scheduling.

摘要： At least one retransmission request is received from each of a plurality of wireless devices receiving a multicast broadcast, and a number of retransmission requests received from each of the plurality of wireless devices is determined. A first group of wireless devices is selected from among the plurality of wireless devices, and a delay time is determined for each wireless device in the first group based on the respective number of retransmission requests from each wireless device. When a data packet is not received at the one or more wireless devices of the first group, a timer is started at each of the wireless devices of the first group using the respective delay times. When the shortest delay time expires, another retransmission request is received from the wireless device comprising the shortest delay time of the one or more wireless devices.

摘要： Estimating uplink interference includes determining any wireless devices having available uplink resources, and instructing the wireless devices to estimate and report uplink interference. A method for estimating uplink interference in a wireless network includes determining that a wireless device attached to an access node has available resources within an uplink schedule of the wireless device, and instructing the wireless device to enter a listening mode during the available resources of the uplink schedule. In the listening mode, the wireless device determines a measurement of an uplink interference caused at the wireless device. The method further includes receiving the measurement of the uplink interference from the wireless device via an uplink channel.

摘要： A transmit power level of a wireless device is adjusted based on an uplink interference to neighboring sectors caused by the transmit power level. The wireless device can estimate the uplink interference using a reference signal transmitted by each neighboring sector. The uplink interference is based on a loss of signal strength of the reference signal as measured at the wireless device, i.e. a path loss. A determination is made to adjust the transmit power level of the wireless device so as to improve a coverage area of the serving sector, without generating excessive interference in neighboring sectors. Consequently, a transmit power level increase is based on a function of the data demand of the wireless device, the interference caused to neighbors, and the load on neighboring sectors.

摘要： Systems and methods are described for allocating resources using enhanced semi-persistent scheduling (SPS) in a wireless network. A plurality of wireless devices may be in wireless communication with an access node. Based on application requirements of the wireless devices, the access node may allocate dedicated resource slots on a persistent schedule for each wireless device requesting SPS services. The wireless devices having the SPS allocations of dedicated resource slots are monitored at intervals for changes in amount of resource usage above or below the size of the dedicated resource slot for each wireless device. If a data transmission for a wireless device exceeds the dedicated resource slot allocated to that wireless device, then the transmission may be truncated, with a first portion being transmitted in the dedicated resource slot and a second portion being transmitted in one or more non-dedicated resource slots.

摘要： Systems and methods are described for allocating resources between frequency bands in a wireless network. A wireless device may establish multiple default channels for wireless communication with two or more cells associated with different frequency bands. The default channels on each of the cells may be used to communicate control signals between the two or more cells and the wireless device. Application requirements may be determined and each of the cells may assign a dedicated channel for service, and one of the dedicated channels may be selected to provide service to the wireless device based on the determined application requirements.

摘要： 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.
