Abstract: Certain aspects of the present disclosure relate to methods and apparatus for buffer management for a user equipment (UE) for multiple radio access technologies (RATs). Certain aspects provide transmitting data using a first RAT and second RAT to the UE based on an assumed size of a first portion of a buffer at the UE assumed allocated for storing data received by the UE using the first RAT and an assumed size of a second portion of the buffer assumed allocated for storing data received by the UE using the second RAT. The size of the first portion is based on a first number of resources the UE is capable of using for communicating and a second number of resources the UE is configured or allocated to use. The size of the second portion is based on an overall size of the buffer and the size of the first portion.

Abstract: Aspects of the present disclosure describe receiving synchronization signals in wireless communications. A block of synchronization signals can be received from a base station in a first time interval. A beam identifier and a redundancy version associated with the block of synchronization signals can be determined. A broadcast channel can be received based at least in part on a timing associated with the beam identifier. The broadcast channel can be descrambled based at least in part on a scrambling code associated with the redundancy version

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 relate to methods and apparatus for radio link monitoring with BWPs and interference measurements using communications systems operating according to new radio (NR) technologies. Certain aspects provide a method for wireless communication. The method generally includes determining one or more bandwidth parts (BWPs) for radio link monitoring (RLM) based on one or more signals; and configuring a user equipment (UE) to monitor the one or more signals on the one or more BWPs within a maximum channel bandwidth.

Abstract: A method and apparatus for configurable synchronization signal transmissions that reduce complexity of cell synchronization in a new radio wireless communication system is disclosed. For example, the method and apparatus may include generating a first synchronization signal burst set having a first set of synchronization signal blocks, generating at least a second synchronization signal burst set having a second set of synchronization signal blocks, transmitting the first synchronization signal block over a first frequency, and transmitting the second synchronization signal block over a second frequency.

Abstract: A multi-band user equipment (UE) is configured to operate in a single frequency band mode or a multiple frequency band mode. When operating in a single frequency band mode, the UE activates a bypass switch to route uplink signals of a first band around a multiplxer and reduce the insertion loss for the band.

Abstract: Various aspects described herein relate to a user equipment (UE) that can receive a configuration for a radio bearer with an SCell in a radio resource control (RRC) reconfiguration procedure initiated by a primary cell (PCell) serving the UE. A component carrier with the SCell can be activated based at least in part on receiving a control element indicating to activate the component carrier for the radio bearer. It can be determined whether a first deactivation timer, for deactivating the component carrier with the SCell after a period of detected inactivity on the SCell, is configured by the PCell. A second deactivation timer can be configured for deactivating the component carrier with the SCell based at least in part on a determination that the first deactivation timer is not configured by the PCell or that a first configured duration of the first deactivation timer achieves a threshold.

Abstract: Techniques for channel selection in a shared communication medium are disclosed. A communication apparatus may include one or more transceivers, a processor, and memory coupled to the processor and configured to store data and/or instructions. The one or more transceivers may be configured to monitor signaling on a plurality of available channels associated with a communication medium. The processor may be configured to determine an interference level for each of the plurality of available channels based on the monitored signaling, determine that the interference level for each of the plurality of available channels is greater than a first threshold, determine whether a triggering condition is met, and select the first channel of the plurality of channels as an operating channel for a primary radio access technology based on the triggering condition being met, the first channel having an interference level that is greater than a second threshold.

Abstract: Aspects for balancing power output on the plurality of antennas for the transmission of a transport block are disclosed. In accordance with the present disclosure, a transmitter may balance the power output on a plurality of transmit antennas in a multiple-input multiple-output (MIMO) system by having a precoded data block bypass a virtual antenna mapping of the overhead channels (e.g., control channels). Additionally or alternatively, the transmitter may balance the power output on the plurality of transmit antennas by applying an inverse mapping parameter during the precoding process to the transport block to generate a plurality of inverse mapped precoded data blocks. In some examples, the inverse mapping parameter may be an inverse of the mapping parameter. Thus, in accordance with the present disclosure, precoding a transport block may include selecting a precoding weight for each of the plurality of antennas from an unrestricted precoding weight set.

Abstract: Aspects described herein relate to selecting a rank for wireless communications using multiple transmit antenna layers. A first effective throughput achievable using a first rank and based at least in part on a first block error rate (BLER) associated with the first rank can be estimated along with a second effective throughput achievable using a second rank and based at least in part on a second BLER associated with the second rank. The first rank or second rank is selected to be used for transmitting communications over multiple transmit antenna layers based at least in part on comparing the first effective throughput to the second effective throughput, and the selection can be indicated to a transmitting entity from which the communications over the multiple transmit antenna layers are received.
