Abstract: The stability of a channel in a wireless network is evaluated at a node. Upon transmitting a packet from the node on a network channel, a first counter associated with the channel is incremented. Upon receiving an acknowledgment packet responsive to the transmitted packet, a second counter associated with the channel is incremented. A stability metric for the channel is computed based on values stored in the first and second counters. Additionally, interference on a channel of the network is measured at a node. Upon determining that no packet is received during a predetermined time-period on the channel, a received signal strength (RSS) is measured on the channel at an end of the predetermined time-period. Alternatively, upon determining that a packet is received during the predetermined time-period on the channel, the RSS is measured on the channel following completion of the transmission of the packet on the channel.

Abstract: Methods and devices may be provided for aggregating component carriers in the licensed spectrum with at least one component carriers in the licensed exempt spectrum. Control information may be processed in a wireless transmit/receive unit (WTRU) while receiving and sending information on a primary component carrier (PCC) and a supplementary component carrier (SuppCC). A PCC subframe with a control portion and a data portion may be received. Resource assignment information associated with a downlink shared channel on the PCC may be embedded in the control portion of the subframe. Based on the resource assignment information on the PCC, resource assignment information associated with a downlink shared channel on the SuppCC may be identified in the data portion of the PCC subframe. A SuppCC subframe of the shared channel on the SuppCC may be processed as per the identified resource assignment information associated with the downlink shared channel on the SuppCC.

Abstract: A method for transmitting channel status information of a user equipment (UE) in a wireless communication system. The UE reports first channel information to a base station periodically; and reports second channel information to the base station periodically. The first channel information and the second channel information are pieces of information combined to indicate one precoding matrix. The second channel information reported in a specific subframe is calculated based on last reported first channel information. A channel quality indicator (CQI) reported in the specific subframe is calculated based on one precoding matrix indicated by the last reported first channel information and the second channel information reported in the specific subframe.

Abstract: A method for establishing wireless communication between a transmitter and a receiver in a wireless communication system is disclosed. The receiver includes an adaptive array that has at least two antennas. Each antenna receives a signal and produces a received signal. The transmitter includes at least two transmission channels for communicating the signal from the transmitter to the receiver. The wireless communication system suppresses interference at the receiver by applying an interference suppression technique when combining the received signals. The selection of a channel at the transmitter is based on the channel performance at the receiver for each transmission channel. The channel performance is based on a combining technique different from the interference suppression technique.

Abstract: An LTE preemption system may allow authorized users to access LTE spectrum when needed by the authorized users and allow commercial users to access the LTE spectrum when not in use by the authorized users. An authorized transmission unit may transmit noise in at least one of a primary synchronization channel, a secondary synchronization channel, or a physical broadcast channel. The noise may prevent commercial users from accessing the LTE spectrum. At least one of the primary synchronization channel, the secondary synchronization channel, or the physical broadcast channel may be offset by a known time or frequency, and authorized devices may utilize the LTE spectrum by searching for the channels at the offset locations.

Abstract: In order to flexibly manage and broadcast content to electronic devices in a multicast group, a multicast group management protocol allows one or more multicast group masters to be specified. In addition to controlling membership in the multicast group, a multicast group master can define or specify a multicast session, in which content from one or more sources is broadcast to at least a subset of the electronic devices or sinks in the multicast group. The multicast group management protocol supports concurrent broadcasts of content to different multicast sessions. Moreover, the broadcasts in the different multicast sessions may have different: priorities, encoding techniques, quality-of-service policies, reliability, and/or number of parity bits. For example, the different encoding techniques may include different layers in H.264 Scalable Video Coding. Alternatively or additionally, the different number of parity bits may be associated with application layer forward error correction.

Abstract: A system and method for managing offer and user equipment movement driven cell system load balancing that overcomes the disadvantages of the prior art. Network elements determine whether a user or user equipment in a first location is within a threshold distance of a second location of better coverage, which is separated from the first location by an intervening region of worse coverage. Upon such a determination, the network can provide a higher level of service as the user moves incrementally between the first and second locations.

Abstract: Wireless transmission is performed by storing, in a local memory, a header in association with reference(s) to memory locations in a separate, shared memory storing a payload for a given transmission. Each header can be associated with a QoS queue. When a selected payload is to be transmitted, a PHY preamble can begin, followed by a header from local memory, while a DMA transaction initiates to retrieve payload from the shared memory. Each retrieved portion of payload can include a link to a next location storing a next part of payload. A subsequent DMA is initiated for that part of the payload. A relatively fixed function circuit can initiate DMA and receive payload data; a programmable element can perform payload selection, for example. Multiple payloads can be aggregated (just before transmitting of a preamble) using header information stored in the fast local memory. Memory can be released after ACK of a corresponding payload.

For a case where two 106-RUs are arranged and a plurality of user stations (STAs) are multiplexed to the respective 106-RUs, a SIG-B field may be used to perform signaling. More specifically, the number of STAs to be multiplexed may be indicated by using first and second identification bits in a user-common field of the SIG-B field.

The processor is configured to execute an instruction to cause content of a select one of the first or second header field's TTL field to be copied to the destination header field.

Abstract: The invention provides a base station that does not cause the number of blind decodings to be increased and further can prevent the flexibility of resource allocation from degrading. A search space setting unit sets search spaces each of which is constituted by one or more control channel elements (CCEs) and each of which is to be decoded in the terminals and each of which is defined by a plurality of to-be-decoded candidates. An allocating unit places, in one of the plurality of to-be-decoded candidates included in the search space, a control channel. The number of connections of CCEs constituting the to-be-decoded candidate is associated with the number of to-be-decoded candidates. The search space setting unit causes, in accordance with the control channel to be transmitted, the association of the number of connections of CCEs constituting the to-be-decoded candidate with the number of to-be-decoded candidates to differ.
