    Abstract: Methods, systems, and devices for wireless communication are described that support overriding a beam monitoring pattern for control channel transmissions based on channel conditions between a user equipment and a base station. A base station may select a beam monitoring pattern for transmitting control channel transmissions, which may include a pattern in which two or more beams are used for control channel transmissions. In the event that a first beam of the beams used in the beam monitoring pattern meets certain metrics, the use of one or more additional beams according to the beam monitoring pattern may be overridden and transmissions continued using the first beam. The metrics for continuing use of the first beam may include channel quality metrics, a number of consecutive successful transmissions using the first beam, one or more other metrics, or any combination thereof.

    Abstract: Techniques providing opportunistic frequency switching for frame based equipment (FBE), such as may be configured to minimize opportunistic frequency switching delay in FBE new radio (NR) unlicensed (NR-U) networks and/or to provide frequency diversity FBE access based on offset sequences of medium sensing occasions for the carrier frequencies are disclosed. Within the FBE mode network, a base station may configure a pattern of sensing locations in each frame for each frequency transmission unit of the plurality of frequency transmission units, wherein an inter-unit delay of sensing locations between a first frequency transmission unit and a next adjacent frequency transmission unit and between a last frequency transmission unit and the first frequency transmission unit is a fixed duration. Opportunistic frequency switching of embodiments may utilize the medium sensing locations for opportunistically switching between a sequence of the frequency transmission units for implementing frequency diversity FBE access.

    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.

    Abstract: A discovery measurement timing configuration (DMTC) window reservation signal is disclosed for new radio (NR) shared spectrum (NR-SS) networks. The DMTC window is defined providing a reserved location for transmission of essential control signaling and potentially high priority traffic that may be transmitted in a prioritized manner. Access within the DMTC window may be provided with a clear channel assessment (CCA) exempt transmission (CET) option or a non-CET option. When the CET option is used, the reservation duration and period may be conveyed through the channel reservation signal. User equipments (UEs) that detect the reservation signal may re-transmit with added offset to inform neighboring base station that may not be within range of the serving base station. Base station that receive either the transmitted or re-transmitted reservation signal will refrain from communications that may interfere with the reception at the UEs.

    Abstract: Systems and methods are provided for physical cell identifier (PCI) and physical random access channel (PRACH) offset joint planning by a network entity that determines an energy level for each of a plurality of PRACH frequency offsets and selects a PRACH frequency offset from the plurality of PRACH frequency offsets, based at least in part on the determined energy levels. The network entity determines a plurality of possible physical cell identifiers (PCIs) for the selected PRACH frequency offset and selects a PCI from the plurality of possible PCIs.
