    Abstract: Methods, systems, and devices for wireless communication are described. A base station may configure a system bandwidth of shared spectrum partitioned into a plurality of bandwidth parts based on interference associated with each of the plurality of bandwidth parts. The base station may then transmit the configuration of the system bandwidth to a plurality of devices. A UE may receive, from a base station, a configuration of a system bandwidth of shared spectrum. The system bandwidth may be partitioned into a plurality of bandwidth parts based on interference associated with each of the plurality of bandwidth parts. The UE may then communicate with the base station on at least one of the bandwidth parts.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station and user equipment (UE) may utilize an enhanced physical downlink control channel (ePDCCH) within a common search space to establish a MulteFire connection. The common search space may include a common PDCCH (C-PDCCH) and a MulteFire system information block (SIB-MF1) grant. The base station may define one or more common search spaces for the SIB-MF1 grants and C-PDCCH and signal the resource allocation for the common search spaces to the UE within a master information block (MIB). Each common search space may include a fixed set of control elements that the UE monitors for decoding the SIB-MF1 grants and C-PDCCH. In some cases, the base station may hardcode resources for the SIB-MF1 grants and C-PDCCH. Alternatively, the base station may signal the resources for each of the SIB-MF1 grants and C-PDCCH via reserved bits in the MIB.

    Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support multi-band operation. Different frequency bands may experience different communication characteristics (e.g., frequency-dependent fading), which may result in undesirable interference patterns and/or coverage gaps. The described techniques provide for a network architecture that optimizes throughput while considering interference metrics. The network architecture may in some cases adapt to changes in the communication environment (e.g., dynamically or semi-statically), and the adaptation may be autonomous or may be performed in conjunction with a coordinating entity. Additionally, the described techniques provide for improved mobility procedures for devices within the network, which may improve throughput, reduce latency, or otherwise benefit the wireless communications system.

    Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support multi-band operation. Different frequency bands may experience different communication characteristics (e.g., frequency-dependent fading), which may result in undesirable interference patterns and/or coverage gaps. The described techniques provide for channel access methods for multi-band operation. The channel access methods may allow for improved throughput for a wireless communications system. Additionally or alternatively, the described techniques may improve energy efficiency for communicating devices, reduce signaling overhead, or otherwise benefit a wireless communications system. Generally, the described techniques provide for efficient anchoring of high-band communications to low-band transmissions.

    Abstract: Methods, systems, and devices for wireless communication are described. The described techniques provide for transmission of uplink data from a user equipment (UE) in the absence of scheduled uplink resources for the uplink data transmission that are allocated to the UE prior to the transmission of the uplink data. Various examples provide uplink configurations that may be used for unscheduled uplink transmissions of a UE, which may be selected dynamically or semi-statically. Unscheduled uplink transmissions may be transmitted in shared radio frequency spectrum according to one or more frame structures, and access to the shared radio frequency spectrum may be determined based on a priority of an operator associated with a UE for accessing the spectrum. Beamforming techniques may be used for transmissions and beam widths may be selected based on the information in a transmission, an operator priority for use of shared radio frequency spectrum, or any combination thereof.

    Abstract: Random access channel (RACH) configurations for new radio (NR) shared spectrum (NR-SS) networks are disclosed. A base station may perform a listen before talk (LBT) procedure on a shared communication channel at a beginning of a discovery measurement timing configuration (DMTC) window. In response to a successful LBT, the base station may transmit synchronization signals over a plurality of directional beams according to a predetermined sequence. The user equipment (UE) may determine the predetermined sequence through the detected synchronization signals. The base station may signal configuration of additional random access resources when the LBT procedure delays beyond dedicated random access resources. The base station may then monitor for UEs to transmit random access signals from each direction corresponding to directional beams within the additional random access resources according to the predetermined sequence.
