Abstract: Certain aspects of the present disclosure provide techniques for an improved encoder for reducing repetition in polar codewords. An apparatus for wireless communication is provided. The apparatus includes at least one processor. The at least one processor is coupled with a memory. The at least one processor includes at least one encoder circuit configured to encode a set of information bits based on a cyclic redundancy check (CRC)-aided polar code to produce a codeword including polar encoded information bits and CRC bits. The at least one encoder circuit is configured to place one or more of the CRC bits at a start of the codeword and to set a value of the one or more CRC bits to a non-zero value. The apparatus includes a transmitter configured to transmit the codeword in accordance with a wireless technology across a channel via one or more antenna elements situated proximate the transmitter.

Abstract: Antenna ports on wireless devices may be QCL. QCL antenna ports may be useful in improving channel statistics related to the antenna ports. UEs and base stations may be able to determine candidate QCL ports, transmit information identifying the candidate QCL ports, and receive feedback indicating whether the candidate QCL ports are QCL at the receiving device such as a UE or a base station.

Abstract: A first apparatus may communicate with a user equipment through a first active beam. The first apparatus may determine that beam tracking is to be performed with the UE, including identifying a new beam for communication between the UE and the apparatus. The first apparatus may perform beam tracking with the UE based on the determination that beam tracking is to be performed. The first apparatus may communicate with the UE through a second active beam based on the beam tracking.

Abstract: Aspects of the present disclosure provide a mechanism for flexible scheduling of grants for downlink or uplink transmissions. In some examples, a grant may be scheduled using multiple control signals, where subsequent control signals may modify one or more properties of the grant. For example, the grant may be modified to add a packet to the grant for transmission on a different set of time-frequency resources or a different set of multiple-input multiple-output (MIMO) layers, modify a time-frequency resource allocation of the grant, modify the waveform utilized for the grant, modify the transmit-diversity scheme utilized for the grant, or indicate specific processing for the packet.

Abstract: A control resource region of an New Radio system slot structure may be separated into control resource sets, only some of which may be used for control transmissions. Aspects presented herein improve the efficient utilization of resources by enabling data transmission in resources of the DL control resource region and/or the UL control resource region. A UE receives an indication of a control resource set in a control resource region of a slot that may provide a control channel resource or a data channel resource and performs rate matching for data transmissions in the data channel based at least in part on the indication. The indication may be a semi-static indication, e.g., RRC signaling, of the control resource set.

Abstract: Certain aspects of the present disclosure provide techniques for assisted power control for an uplink signal transmitted during a RACH procedure. A UE may determine a transmit power for transmitting a message during a RACH procedure with a secondary BS, based at least in part, on communication between the UE and a primary BS. The UE may transmit the message to the second BS during the RACH procedure based, at least in part, on the determined transmit power.

Abstract: In millimeter wave systems, user equipment may not be able to receive RACH parameters through a PDCCH when the information is transmitted with an omni-directional beam. In an aspect of the disclosure, an apparatus, such as a base station, may determine the RACH parameters and transmit a subset of the RACH parameters via a PBCH. The user equipment may receive the RACH parameter subset and initiate a RACH procedure.

Abstract: In a process of beam change, the base station transmits a beam change instruction to a user equipment to confirm a change from a current beam to another beam. The base station determines to change from a first beam to a second beam. The base station generates a beam change instruction to indicate the determination to change from the first beam to the second beam. The base station transmits, to a UE, the beam change instruction in a downlink control information (DCI). The base station determines whether or not the beam change instruction is detected by the UE.
