Abstract: A first apparatus may puncture, in at least two subslots, a first type of data or control information with a second type of data or control information. The first apparatus may bundle the least two subslots within a subframe, and the subframe may include a portion for carrying acknowledgment (ACK)/negative acknowledgment (NACK) information associated with the second type of data or control information. The first apparatus may communicate with a user equipment (UE) during the at least two subslots within the subframe. A second apparatus may receive ACK/NACK information associated with a second type of data or control information. The second apparatus may reduce a transmission power for a first type of data or control information during a subsequent subframe when the ACK/NACK information indicates a negative acknowledgement.

Abstract: A receiving device may remain in omni-directional mode while receiving RTS messages from transmitting devices. Multiple devices may transmit RTS messages at the same time, causing interference and preventing intended recipients of the RTS messages from transmitting a CTS message. To increase medium reuse, RTS may be transmitted and received in a slotted and directional manner. A receiving device may select a sweeping pattern for receiving transmission from neighboring devices. The receiving device may also determine one or more time slots allocated to each of the neighboring devices for receiving transmissions from the neighboring devices. The receiving device may transmit an indication of the sweeping pattern and the time slots to one or more of the neighboring devices. Subsequently, during one of the indicated time slots, the receiving device may perform a beam sweep to receive one or more RTS messages from one of the neighboring devices.

Abstract: Certain aspects of the present disclosure provide techniques for assisted power control for an uplink signal transmitted during a RACH procedure. A UE may determine a transmit power for transmitting a message during a RACH procedure with a secondary BS, based at least in part, on communication between the UE and a primary BS. The UE may transmit the message to the second BS during the RACH procedure based, at least in part, on the determined transmit power.

Abstract: The base station that is configured to transmit in a beamformed manner may set different transmission rates for different directions of the beams. During an initial access stage, the base station may determine how densely user equipments are located in various regions surrounding the base station, and may assign more beams for transmission of an initial access signal in an area with more UEs. The apparatus may be a base station. The base station divides a region surrounding the base station into a plurality of sub-regions, where one region of the plurality of sub-regions covers a greater area than at least one other region of the plurality of sub-regions. The base station assigns each beam of a plurality of beams of the base station to a respective sub-region of the plurality of sub-regions. The base station transmits at least one initial access signal in each direction of the plurality of beams using a respective beam of the plurality of beams, each direction of the plurality of beams corresponding to a respective sub-region of the plurality of sub-regions.

Abstract: A method of wireless communication by a user equipment includes determining an allocation of a set of tones in a symbol for conveying data. The method further includes determining to use m-ary phase shift keying (MPSK) to modulate the data onto a subset of tones of the set of tones. The method further includes modulating the data onto the subset of tones based on a mapping, wherein the mapping maps pairs of data values with a largest Hamming distance from each other to pairs of constellation points with a maximum Euclidean distance from each other.
