Abstract: Methods, systems, and devices for delivering system information (SI) in a wireless communications system are described. Approaches described herein include determining different sets of SI corresponding to different sets of devices that might use the SI, and using directional transmissions to transmit the different sets of SI in different directions, so as to only transmit in a given direction SI that may be useful for devices in that direction. Also described herein are approaches for dividing a set of SI into different portions, and transmitting one portion via one or more reference signals and another portion less frequently via a scheduled data channel.

Abstract: A UE may receive a beam modification command that indicates a set of transmit beam indexes corresponding to a set of transmit beams of a base station, and each transmit beam index of the set of transmit beam indexes may indicate at least a transmit direction for transmitting a transmit beam by the base station. The UE may determine a set of receive beam indexes corresponding to receive beams of the UE based on the set of transmit beam indexes, and each receive beam index of the set of receive beam indexes may indicate at least a receive direction for receiving a receive beam by the UE. The UE may receive, from the base station, a signal through at least one receive beam corresponding to at least one receive beam index included in the set of receive beam indexes.

Abstract: Backhaul resources may be allocated to different wireless communication links between different base stations, and local redistribution of resources among base stations may be utilized to account for variations in signal quality and/or variations in traffic experienced by different nodes of the backhaul network. A first access node function (ANF) may determine a need for additional backhaul resources, and may transmit a request message to one or more user equipment functions (UEFs) for additional backhaul resources. A UEF that receives the request message may forward the request to an associated second ANF. The second ANF, if it has backhaul resources available that the first ANF can use, may send a response to the first ANF, via the associated UEF, and the first ANF may use the additional resources that were originally allocated to the second ANF.

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: Various aspects of the disclosure provide for methods of communication. One method, at a base station, involves determining a maximum number of consecutive MSG1 retransmissions that a user equipment (UE) is permitted to perform, and transmitting the maximum number of consecutive MSG1 retransmissions to the UE. Another method involves receiving a maximum number of consecutive MSG1 retransmissions to be performed, and transmitting consecutive MSG1 retransmission signals for the maximum number of times.

Abstract: Antenna ports on wireless devices may be QCL. QCL antenna ports may be useful in improving channel statistics related to the antenna ports. UEs and base stations may be able to determine candidate QCL ports, transmit information identifying the candidate QCL ports, and receive feedback indicating whether the candidate QCL ports are QCL at the receiving device such as a UE or a base station.

Abstract: A transmitting device may determine that a first neighbor device is communicating with a second neighbor device based on a signal received from the first device (e.g., a request-to-send (RTS) signal) during a listen-before-talk (LBT) period. The transmitting device may also identify a direction of the second neighbor device (e.g., based on signals received during a previous LBT period), and determine the amount of interference that a directional transmission may cause at the second neighbor device. The determination may be based on whether the transmission direction (i.e., a beam direction of a directional transmission) is in a same direction as the second neighbor device. If the interference level is below a threshold, the transmitting device may perform the transmission despite receiving the signal during the LBT period. If the interference level is above the threshold, the transmitting device may refrain from transmitting.

Abstract: Methods, systems, and devices for wireless communication are described. Synchronization signals may be transmitted using a set of phase offsets over different component carriers or using a single component carrier for each antenna port. For example, a base station may identify a set of synchronization signals (e.g., a set of primary synchronization signals (PSSs)) to be transmitted over one or multiple component carriers. In some cases, each PSS may be associated with a different component carrier, and the base station may apply a different phase offset to each PSS when transmitting the set of PSSs on the component carriers. In some examples, the base station may transmit the PSSs on the component carriers using a different antenna port for each component carrier.

Abstract: Methods, systems, and devices for wireless communication are described. In particular, a backhaul network that may be established between access nodes and/or base stations is shown and described. To support communications via the backhaul network, a synchronized frame structure and unique network topologies may be established. Resources may be allocated to different wireless communication links based on the synchronized frame structure. Occupancy/availability indications are shown and described, which enable the local redistribution of resources to account for variations in signal quality and/or variations in traffic experienced by the backhaul network.

Abstract: Methods, systems, and devices for wireless communication provide for split symbol control by varying tone spacing and symbol duration for control channels in a subframe. The control symbols may be transmitted at various locations within the subframe and may be transmitted to different mobile devices. In some examples, multiple control symbols may be transmitted in a subframe to multiple mobile devices depending on the capabilities of each of the multiple mobile devices.
