The present disclosure describes various examples of a method, an apparatus, and a computer readable medium for signaling synchronization block patterns in wireless communications (e.g., 5th Generation New Radio (5G NR)). For example, one of the methods described may include receiving, by a user equipment (UE), a message including information of a configuration. The configuration includes at least a group of repetitions of one or more synchronization signal (SS) blocks in an SS burst set, and the repetitions of the one or more SS blocks are configured into at least two groups. The method may further include determining, by the UE, which group of the at least two groups to search for during a synchronous neighbor cell search based on the information and at least one condition at the UE.

Facilitating semi-open loop based transmission diversity for uplink transmissions in a communications network is provided herein. A system can comprise a processor and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations can comprise receiving, from a network device, information related to a sounding reference resource. The information related to the sounding reference resource can be based on a sounding reference signal resource transmission detected during a defined time interval. The operations can also comprise, based on a selected weight vector cycling, selecting a weight vector from defined weight vectors stored in the memory, resulting in a selected weight vector. Further, the operations can comprise transmitting, to the network device, a signal that comprises the selected weight vector multiplied with the sounding reference signal, during the selected weight vector cycling.

The present disclosure provides for centralized, scheduler-based handling for UEs which transmit data to and receive data from a maneuver coordinator based on V2X communication. Once a UE is aware of the maneuver coordinator, the UE may send a request to the maneuver coordinator for maneuver operation scheduling. The maneuver coordinator then schedules and coordinates the UE's operation.

Methods and systems for coordinating simultaneous transmission by two or more access points over a single channel of a wireless medium are disclosed. In one aspect, a method includes determining, by a first access point, a time when the first access point and a second access point will transmit simultaneously over the channel, and transmitting, by the first access point, over the channel at the time.

Methods, systems, and devices for wireless communication are described for dynamic frozen bits of polar codes for early termination and performance improvement. A wireless device may receive a signal comprising a codeword encoded using a polar code. The wireless device may perform decoding of the codeword including at least: parity check of a first subset of decoding paths for making a decision on early termination of decoding of the codeword based on dynamic frozen bits, and generating path metrics for a second subset of the decoding paths that each pass the parity check based on the dynamic frozen bits, and performing error detection on a bit sequence corresponding to one of the second subset of the decoding paths based at part on error detection bits and the generated path metrics. The wireless device may process the information bits based on a result of the decoding.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a downlink (DL) signal from a base station on one or more DL beam(s). The UE may identify a selected DL beam of the one or more DL beam(s) for communications from the base station to the UE. The UE may transmit a beam recovery or beam tracking message to the base station using at least one of a resource or a waveform selected based at least in part on the selected DL beam.

There is a need to support narrowband TDD frame structure for narrowband communications. The present disclosure provides a solution by supporting one or more narrowband TDD frame structure(s) for narrowband communications. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a narrowband TDD frame structure for narrowband communications from a group of narrowband TDD frame structures. In one aspect, the narrowband TDD frame structure may include a set of downlink subframes and more than one special subframe. The apparatus may determine a set of narrowband carriers and a minimum set of subframes on the set of narrowband carriers based at least in part on the set of downlink subframes and more than one special subframe on which a NRS should be transmitted. The apparatus may transmit the NRS using the narrowband TDD frame structure determined for the narrowband communications.

Bandwidth part (BWP) switching may benefit a wireless communications system. Such BWP switching may include indication of one or more timing parameters used for time domain resource allocation. For example, the timing parameters may be indicated based on an index to a look-up table (e.g., a bit field in a control transmission). In some cases, one or more tables may be configured for a given BWP, and different tables may contain a different number of rows. The size of the bit field indexing the table may in turn depend on the number of rows. When switching from a first BWP to a second BWP, the size of the bit field may be based on the table of the first BWP, but the bit field may index the table of the second BWP. Techniques supporting improved timing parameter management during BWP switching are discussed herein.

The apparatus may communicate with a UE using the narrowband TDD frame structure determined for the narrowband communications.
