Abstract: Methods, systems, and devices for wireless communications are described. One method may include receiving, by a user equipment (UE) from a base station, a resource allocation indicator corresponding to a total number of resource elements to allocate for uplink control information within a resource allocation of a shared data channel. The UE may determine anchor resources within the resource allocation, and determine a plurality of transmission parameters for an autonomous uplink transmission based on the total number of resource elements. The UE may transmit, to the base station, the uplink control information within the anchor resources to indicate the plurality of transmission parameters for the autonomous uplink transmission.

Abstract: Wireless communications systems and methods related to communicating in a shared communication medium with flexible scheduling are provided. A first wireless communication device communicates, with a second wireless communication device during a reservation period, a channel reservation request for a first transmission opportunity (TXOP) in a spectrum. The first wireless communication device communicates, with the second wireless communication device during a response period in response to the channel reservation request, a channel reservation response. The first wireless communication device communicates, with a third wireless communication device during a first time period between the reservation period and the response period, a first communication signal.

Abstract: Wireless communications systems and methods related to coordinating shared radio resources for spectrum sharing are provided. A spectrum resource control unit allocates a first resource for exclusive access by a first network operating entity in a spectrum. The exclusive access is configured for at least one of a network information communication or a feedback communication. The spectrum resource control unit allocates a second resource in the spectrum for shared access by the first network operating entity and a second network operating entity. The shared access is configured for at least a downlink control information communication. The spectrum resource control unit transmits, to the first network operating entity and the second network operating entity, a configuration indicating the first resource allocated for exclusive access by the first network operating entity and the second resource allocated for shared access by the first network operating entity and the second network operating entity.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a coreset of time and frequency resources within a control region of a coreset bandwidth. In one aspect, the coreset bandwidth may be based on a minimum bandwidth configuration associated with one or more UEs in a set of UEs. The apparatus may also transmit a PDCCH as a single-carrier waveform via the coreset of time and frequency resources. In one aspect, the PDCCH may be transmitted to each UE in the set of UEs using the coreset bandwidth.

Abstract: Aspects of the disclosure relate to a dynamic, configurable time division duplex (TDD) frame structure for hopping superframes utilized in narrowband Internet of Things (NB-IOT) wireless communication systems. The configurable frame structure includes an anchor segment residing on a plurality of anchor hopping frequencies and a data segment residing on one of a plurality of non-anchor hopping frequencies. The data segment includes a downlink portion, an uplink portion, and a configurable portion between the downlink control portion and the uplink control portion that may be configured to include at least one of downlink information or uplink information.

Abstract: Methods, systems, and devices for wireless communications are described that provide for refinement of receive beam beamforming parameters at a user equipment (UE). A UE may transmit two or more signals in an uplink transmission that have different beamforming parameters. A base station receiving the uplink transmission may measure the two or more signals, and identify a first signal of the two or more signals based at least in part on the measuring. The base station may inform the UE of the identified first signal, which the UE may use to set receive beam beamforming parameters for one or more subsequent downlink transmissions.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for sounding reference signal (SRS) coordination, power control, and synchronization for distributed coordinated multipoint (CoMP) using communications systems operating according to new radio (NR) technologies. For example, a method for wireless communications by a network entity includes determining a first amount of transmission (Tx) power for transmission of signals originating from a first cluster center that is connected to the network entity, determining a second amount of Tx power for transmission of signals originating from at least a second cluster center that is connected to the network entity, and transmitting signals for one or more user equipment (UEs) served by the first cluster center and one or more UEs served by the second cluster center based on the first amount of Tx power and the second amount of Tx power.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless networks (e.g., MulteFire networks), a base station may transmit control information to a user equipment (UE) to enable the UE to access the network and establish a connection with the network. The base station may transmit the control information to the UE in search spaces of an enhanced physical downlink control channel (ePDCCH). In some cases, resources used to transmit control information in a first common search space of the ePDCCH may overlap with resources used to transmit control information in a second common search space of the ePDCCH. In such cases, using the techniques described herein, a base station may encode control information transmitted in the different types of search spaces using different scrambling sequences. As such, a UE may be able to differentiate between the control information transmitted in the different types of common search spaces.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. In one configuration, the apparatus may receive, from a base station, first information associated with one or more resources allocated for at least one PRACH transmission. In one aspect, the one or more resources may be allocated in an unlicensed spectrum. In another aspect, the one or more resources may be allocated based on a multi-tone PRACH bandwidth. The apparatus may also receive second information associated with a frequency hopping configuration from the base station. In one aspect, the frequency hopping configuration may be associated with at least one of the one or more allocated resources or the multi-tone PRACH bandwidth. The apparatus may transmit, to the base station, the at least one PRACH transmission using the one or more allocated resources within the multi-tone PRACH bandwidth and the frequency hopping configuration.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may schedule an autonomous uplink (UL) transmission and a scheduled UL transmission during the same time period. The wireless device may determine that it is operating in a limited power state and therefore cannot transmit both the autonomous UL transmission and the scheduled UL transmission. The wireless device may prioritize one of the autonomous UL transmission and the scheduled UL transmission based at least in part on a priority configuration. The wireless device may receive the priority configuration from a base station (e.g., in radio resource control signaling).
