Abstract: Certain aspects provide methods and apparatus for wireless communications. One example method generally includes receiving a shared channel within a subframe, determining the same precoding may be used across resource blocks belonging to the same precoding resource block group (PRG) of the shared channel, and processing the shared channel based on the determination.

Abstract: Methods, systems, and devices for wireless communication are described. One method may include receiving, at user equipment (UE), a control resource set configuration message from a base station; identifying an overlap between a first control resource set and a second control resource set of a wireless channel; identifying a priority level of the first control resource set and a priority level of the second control resource set based on the control resource set configuration message; and monitoring the first control resource set based on the identified overlap, the priority level of the first control resource set, and the priority level of the second control resource set.

Abstract: Techniques are described for wireless communication. A first method includes winning a contention for access to an unlicensed radio frequency spectrum band, and transmitting at least a portion of a channel usage beacon signal (CUBS) over the unlicensed radio frequency spectrum band. The at least portion of the CUBS is transmitted in a number of frequency interlaces of the unlicensed radio frequency spectrum band. A second method includes winning a contention for access to an unlicensed radio frequency spectrum band; determining whether the contention is won within a threshold time before a next symbol period boundary; and transmitting at least a portion of a CUBS over the unlicensed radio frequency spectrum band. The at least portion of the CUBS is transmitted during a preamble including a fractional period of a first symbol period. The at least portion of the CUBS may be based at least in part on the determining.

Abstract: The present application relates to slot format indicator signaling in wireless communication systems. For example, a network entity may configure a slot format to include one or more symbol partitions and a transmission assignment for each of the one or more symbol partitions, and communicate with to at least one UE according to the configured slot format. In another example, a UE may configure at least one slot format according to at least one of a semi-static configuration via a broadcast or unicast transmission, or a dynamic configuration via a group common physical downlink control channel (GC-PDCCH), and communicate with the network entity according to the slot format.

Abstract: Wireless communication devices are adapted to facilitate multiple synchronization channels within a single carrier. In some examples, an apparatus for wireless communication may transmit a first synchronization channel at a first frequency in a carrier bandwidth, and at least one additional synchronization channel at a different respective frequency in the carrier bandwidth. In some examples, an apparatus for wireless communication may scan a carrier bandwidth for one of a plurality of synchronization channels conveyed at different respective frequencies in the carrier bandwidth, and discover a synchronization channel from among the plurality of synchronization channels. The apparatus may further receive information conveyed over the discovered synchronization channel and utilize the information to access the carrier. Other aspects, embodiments, and features are also included.

Abstract: Methods, systems, and devices for wireless communication are described. Wireless communications systems as described herein may be configured to support several service types with different latency, reliability, or throughput rates or standards. One such service type may be referred to as ultra-reliable, low-latency communications (URLLC). Enhancements to improve URLLC performance in coexistence with and as a complement to legacy service types, such as LTE are described. These include, for example, enhanced timing resource allocations, enhanced transmission repetition schemes, enhanced feedback mechanisms, or a combination of these features to achieve certain reliability and latency targets.

Abstract: A modified subframe structure is defined for a subset of a plurality of subframes. The modified subframe structure includes a first portion with one or more blank symbols over which a network node can measure monitor to determine whether the subframe is used as a downlink (or uplink) subframe by a neighboring network node. The modified subframe structure can also include a second portion of symbols for communicating control information or data in the subframe, which can be based on determining whether the subframe is used as a downlink (or uplink) subframe by the neighboring network node. This can lessen the impact of possible interference caused by the network nodes dynamically switching time division duplexing (TDD) subframe configurations by enabling network nodes to determine when a neighboring node is transmitting in a subframe, and accordingly avoiding transmitting in the subframe.

Abstract: Aspects of the disclosure relate to wireless communication systems configured to provide techniques for strategically placing a sounding reference signal (SRS) within a slot to improve the decoding timeline. Aspects of the disclosure further relate to wireless communication systems configured to optimize the physical downlink control channel (PDCCH) search space within a slot to improve the decoding timeline. Features may also include placing the SRS near the end of the slot, such as after the uplink user data traffic and the corresponding uplink demodulation reference signal (DMRS). In addition, features may also include identifying the PDCCH search space within the slot based on at least a slot index of the slot. Other aspects, embodiments, and features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for sounding reference signal (SRS) triggering and power control for coordinated multi-point (CoMP) operations. One method generally includes maintaining separate power control processes for at least a first aperiodic SRS (A-SRS) and a second A-SRS, receiving, in a first subframe, a downlink transmission triggering transmission of at least one of the first and second A-SRS in a subsequent subframe, identifying which of the first and second A-SRS to transmit in the subsequent subframe, receiving a first power control command that indicates a power control value to apply to the identified A-SRS, and transmitting the identified A-SRS based in accordance with the first power control command.

Abstract: Various aspects described herein relate to rate matching around reference signaling. A discovery reference signal (DRS) configuration is received that identifies first resources related to non-zero power reference signals for DRS transmitted by a cell over a first bandwidth and second resources related to zero power reference signals for the DRS over a second bandwidth. The first bandwidth can be less than or equal to the second bandwidth. At least one channel can be received from the cell along with an instance of the non-zero power reference signals and the zero power reference signals. Rate matching can be performed for the at least one channel around the second resources over the second bandwidth.
