Abstract: Methods, systems, and devices for wireless communication are described. A transmitter, such as a user equipment and/or a base station, may perform polar coding to encode bits. The polar coding may be associated with a plurality of component channels associated with a polar code length. The transmitter may interleave the encoded bits. The transmitter may map the interleaved encoded bits to a modulation symbol. The interleaving and mapping of each encoded bit may be based on an asymmetry of a polar code construction. The transmitter may transmit the interleaved encoded bits based on the mapping.

Abstract: A UE may identify a first indication associated with a first signaling to be received in a time interval and identify a second indication associated with a second signaling to be received in the time interval. The UE may select to receive and receive, in the time interval, at least one of the first signaling or the second signaling based on at least one of the first or second indications. One or more of the first and second indications may be received from a BS or determined by the UE via predefined or other means. A BS may convey indications of the first and/or second signaling. The first and second indications may be transmitted sufficiently before the signaling in an effort to allow the UE to select and tune its receiver beam in the direction of the signaling to be received.

Abstract: Certain aspects of the disclosure provide techniques for a user equipment (UE) to determine a receive beam of a plurality of receive beams for receiving an upcoming transmission from a base station, wherein the determining is based on whether an indication is received from the base station indicating if the upcoming transmission includes a reference signal (RS) multiplexed with additional data. The techniques further provide for the UE to receive the upcoming transmission using the determined receive beam.

Abstract: Methods, systems, and devices are described for wireless communication. In one method, a method of wireless communication at a user equipment (UE) includes receiving a synchronization signal. The synchronization signal may be common to a plurality of cells within a network. The method further includes acquiring a timing of the network based on the synchronization signal, and transmitting a pilot signal in response to acquiring the timing of the network. The pilot signal may identify the UE and be concurrently receivable by the plurality of cells within the network. Other aspects, features, and embodiments are also claimed and described.

Abstract: 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.

Abstract: The choice of a transmit (Tx)-Receive (Rx) beam pair out of many available beam pairs between a base station and a millimeter wave (mmW)-capable UE is directly related to the performance of transmission between the base station and the UE. A method, apparatus, and computer-readable medium at a transmitting user equipment (UE) capable of (mmW) communication are disclosed to determine a new serving Tx-Rx beam pair based on priorities of the plurality of Tx-Rx beam pairs. The UE may select a Transmit (Tx)-Receive (Rx) beam pair from a plurality of Tx-Rx beam pairs available at the UE for measurement, based in part on a priority of the Tx-Rx beam pair, and update the priority of the selected Tx-Rx beam pair based in part on a combination of static information and dynamic information of the selected Tx-Rx beam pair.

Abstract: According to an aspect of the disclosure, a base station may convey the parameter information to the UE based on selection of particular resources to be used for transmission of synchronization signals, where the selected resources correspond to the particular parameter information. The UE may blindly detect the synchronization signals on various candidate resources and determine the parameter information based on the resources where the synchronization signals are detected. The apparatus may be a base station. In an aspect, the base station determines parameter information of one or more parameters. The base station selects, based on the parameter information, synchronization resources from a plurality of candidate resources for transmission of one or more synchronization signals, where the selected synchronization resources correspond to the parameter information. The base station transmits the one or more synchronization signals using the selected synchronization resources.

Abstract: Embodiments herein maximize frame usage by selectively arranging the data within the frame thereby giving the transmitting processor additional time generate and transmit the data within the frame without increasing the time gap G of the frame and without increasing the overall length of the frame. Further, the selective arrangement also gives the receiving processor additional time to process the data of the frame and send Ack/Nack information regarding the success/failure of the processing without increasing the time gap G of the frame and without increasing the overall length of the frame. Other aspects, embodiments, and features are also claimed and described.
