Abstract: A method for radio communication between a transmitting node and receiving nodes comprises obtaining (S1) of directions from the transmitting node to the receiving nodes and antenna gains needed for each direction. A beam forming solution having a high gain in the directions of a set of receiving nodes and with antenna gains adapted to the need of the link is obtained (S2). User data to be transmitted to the receiving nodes is obtained (S3). The user data is overlay-coded (S4) by a code-domain overlaid code and/or a frequency-domain overlaid code, separately for each respective receiving node. The overlaid-coded user data is combined (S5) into at least one combined signal stream. Analogue beamforming, hybrid beamforming or constrained beamforming is performed (S6) on the combined signal stream(s) according to the beam forming solution. The beamformed data is transmitted (S7) from the transmitting node to the receiving nodes.

Abstract: Exclusion functionality for License Assisted Access, LAA, in LTE is defined. LAA exclusion is a temporary deactivation or throttling of scheduling on LAA Secondary Cells (SCells), which allows a requesting UE (11) to periodically, or upon demand, send data or perform measurements on Wi-Fi networks using the same receiver circuitry (18), e.g., radio front end, without risk of losing LAA traffic. A UE sends an exclusion request to its serving base station, eNB (31) and receives an acknowledgement. The UE (11) may include parameters, e.g., duration or periodicity, in the request, and the acknowledgement may include overriding parameters. By the introduction of the exclusion functionality, the UE (11) can share receiver circuitry (18) between Wi-Fi and LAA, hence reducing hardware device size, cost, and power consumption.

Abstract: A second device that is in communication with a first device receives transmissions of the first device and detects a SILENCE period status of the first device, which corresponds to a status wherein the first device has no speech samples to be transmitted towards the second apparatus. The second device determines the type of the received transmissions, counts the number of received transmissions of a first type, and times a time interval between the last received transmission of the first type and the last received transmission of a second determined type. At reception of a transmission of the first type, the second device detects whether the first device is in the SILENCE period status on an evaluation of the counted number of transmissions of the first type and the time interval of the last received transmission of the first type and the last received transmission of the second type.

Abstract: A method includes a base station in a distributed antenna system having a set of antennas. For each antenna, the base station stores state information indicating that the antenna is either in a transmit state or a do_not_transmit state.

The base station adjusts the state information in accordance with a transmit status.
