Certain aspects of the present disclosure generally relate to wireless communications, and more specifically, to physical broadcast channel (PBCH) or other type channel repetition for enhanced machine type communication (eMTC). According to certain aspects, a method is provided for wireless communications by a base station (BS). The method generally includes determining a repetition pattern indicating subframes of a radio frame in which a channel is to be transmitted and transmitting the channel according to the determined repetition pattern.

A satellite reception assembly may comprise a first module operable to demodulate a first one or more channels of a signal output by a direct broadcast satellite (DBS) low noise block downconverter (LNB). The first module may output a signal to a second module which may demodulate a second one or more channels of the signal output by the DBS LNB. The second module may be installed after the satellite reception assembly has been deployed upon a number of clients served by the satellite reception assembly reaching a threshold.

A wireless communication system that includes a base station and one or more terminals carries out wireless data communication by use of a first frequency band. The wireless communication system includes a wireless access system that employs a CSMA/CA and/or TDMA/TDD system as the wireless access system of the wireless communication system and a control signal at the first frequency band is periodically broadcasts from the base station, where the control signal includes a control information configured to manage wireless data transmission by the one or more terminals. In addition to the first frequency band, one or more frequency bands different from the first frequency band for the wireless data transmission by the one or more terminals can be allocate by the base station, where the control signal at the first frequency band indicate the location of the one or more frequency bands which can be used.

A satellite reception assembly that provides satellite television and/or radio service to a customer premises may comprise a wireless interface via which it can communicate with other satellite reception assemblies. Wireless connections between satellite reception assemblies may be utilized for providing satellite content between different satellite customer premises. Wireless connections between satellite reception assemblies may be utilized for offloading traffic from other network connections.

Disclosed are a method and a device for receiving a frame in a wireless LAN. A method for receiving a frame in a wireless LAN comprises the steps of: an AP transmitting an RTS frame to a plurality of STAs, wherein the RTS frame comprises information for NAV setting of an STA other than the plurality of STAs; the AP receiving from each of the plurality of STAs, as a response to the RTS frame, a CTS PPDU and an additional CTS PPDU on overlapped time resources; and the AP transmitting an uplink transmission indication frame to the plurality of STAs, wherein the uplink transmission indication frame triggers transmission of an uplink frame of each of the plurality of STAs.

A method of providing spatial diversity for critical data delivery in a beamformed mmWave smallcell is proposed. The proposed spatial diversity scheme offers duplicate or incremental data/signal transmission and reception by using multiple different beams for the same source and destination. The proposed spatial diversity scheme can be combined with other diversity schemes in time, frequency, and code, etc. for the same purpose. In addition, the proposed spatial diversity scheme combines the physical-layer resources associated with the beams with other resources of the same or different protocol layers. By spatial signaling repetition to avoid Radio Link Failure (RLF) and Handover Failure (HOF), mobility robustness can be enhanced. Mission-critical and/or time-critical data delivery can also be achieved without relying on retransmission.

Disclosed is a method for monitoring the wavelength of a tunable laser device of user by local OLT. The method is applied to a wavelength division multiplexing passive optical network framework. The framework comprises an ONU, a first athermal array waveguide grating, a transmission optical fiber, a second athermal array waveguide grating and the OLT, which are sequentially connected. ONU comprises tunable wavelength optical transmitters. The method comprises: starting handshaking is carried out between the OLT and the ONU; and the OLT carries out wavelength drifting monitoring during operation of the ONU. Wavelength adjustment can be carried out on the multi-channel tunable laser device in an external auxiliary monitoring environment, thus channel wavelengths of the multi-channel tunable laser device can be accurately controlled, and the requirement for calibration accuracy of channels of the tunable laser device at the ONU is greatly reduced.
