    Abstract: In some embodiments, only one multicast connection identifier is used in a WiMAX network per zone. This may result in power savings because it is not necessary for the mobile station to query a base station to obtain the correct information about how to locate desired channels in a WiMAX multicast. Instead, the mobile station may be maintained in a lower power consumption mode in which it need not transmit, but only receives information. This is because the mobile station has all the information it needs about what channels are available and can simply tune using a logical media channel identifier to the appropriate channel to receive the desired content without having to transmit a message to the base station to identify the correct channel.

    Abstract translation: 在一些实施例中，在每个区域的WiMAX网络中仅使用一个多播连接标识符。 这可能导致功率节省，因为移动台不需要查询基站以获得关于如何在WiMAX多播中定位所需信道的正确信息。 相反，移动台可以维持在不需要发送的较低功耗模式中，但是仅接收信息。 这是因为移动台具有所需的关于哪些信道可用的所有信息，并且可以简单地使用逻辑媒体信道标识符调谐到适当信道以接收所需内容，而不必向基站发送消息以识别正确的 渠道。

    Abstract: A system and method for optimizing random access control, and for optimizing transmission efficiency of data packets over reverse common channels between access terminals and a base station, in a wireless communications system. In the communications system, at least one of the access terminals is adapted to transmit at least a portion of an access data packet to the base station, and the base station is adapted to receive the portion of the access data packet and, in response, to transmit a message for receipt by the plurality of access terminals which indicates receipt of the access data packet portion by the base station and identifies the access terminal from which said access data packet portion is received. The message can control the other access terminals to refrain from transmitting an access data packet, while indicating receipt of the access data packet portion to the certain access terminal from which the access data packet portion had been transmitted. The base station can also provide power control signals to control transmission power of that certain access terminal, and to control that certain access terminal to transmit over certain reverse channels. Accordingly, interference between access data packets being transmitted by multiple access terminals and being received in the same time slot by a base station in a wireless communications system can also be minimized.

    Abstract: A communication system is used to transmit and receive a plurality of relatively narrow-band signals and wideband signals. The two signal types share a common electromagnetic spectrum by employing spreading gain and maintaining orthogonality between simultaneously transmitted wideband and narrow-band signals. Signal orthogonality is maintained by selectively choosing orthogonal codes and aligning or spacing a wideband carrier frequency with respect to the narrow-band carrier frequencies in accordance with the ratio of the wideband to the narrow-band chip frequencies. A pilot signal is preferably transmitted contemporaneously with the transmission of the first spreaded signal, and a control data signal, associated with a plurality of users on the first bandwidth, is transmitted on a common control channel using a single Walsh code that is shared by a plurality of users in a TDMA protocol. Further, if the length of the message intended for transmission by the wideband transceivers is below a message length threshold, the message can be transmitted using a common access channel shared by the wideband transceivers. Still further, by adapting the data transmission rate, in response to the data error rate and transmitter power level, the transmission range and/or the data transmission rate can be optimized.

    Abstract: Briefly, in accordance with one or more embodiments, user equipment receives unicast services from a first carrier of a primary serving cell and determines if Multimedia Broadcast and Multicast services (MBMS) services are available on a second carrier based at least in part on information in a broadcast carrier channel that indicates the second carrier or an identification (ID) of the second carrier. If MBMS services are available on the second carrier, the user equipment at least temporarily switches to the second carrier to receive the MBMS services. The user equipment may provide feedback to the network or the primary serving cell when it starts and stops receiving MBMS services, and then may switch back to the primary serving cell when MBMS services have ended or the user equipment no longer desires to receive MBMS services.

    Abstract: Embodiments of the present disclosure describe devices, methods, computer-readable media, and systems configurations for configuration of downlink coordinated multipoint (CoMP) communications in a wireless communication network. A user equipment (UE) may receive, from an evolved Node B (eNB), a radio resource control (RRC) transmission including channel state informations (CSI) reference signal (RS) parameters for a plurality of transmission points. The UE may subsequently receive a medium access control (MAC) control element (CE) including a plurality of index bits corresponding to one or more activated transmission points of the plurality of transmission points for which the feedback module is to generate CSI-RS feedback. The eNB may dynamically update the transmission points that are activated for CSI-RS feedback. The UE may receive another MAC CE from the eNB to notify the UE of the updated set of activated transmission points.
