Abstract: Aspects of the present disclosure relate to deriving spatial receive parameters for quasi-colocation at a user equipment (UE). An exemplary method generally includes receiving a plurality of beams from a base station in a plurality of coarse directions, determining, based on the plurality of beams, a first spatial colocation parameter, transmitting an indication of a coarse direction associated with a beam having a highest receive strength of the plurality of beams, receiving a plurality of second beams from the base station based on the indication, the plurality of second beams having a narrower beam width than the plurality of beams and covering a beam width of the beam associated with the indicated coarse direction, determining, based on the plurality of second beams, a second spatial colocation parameter, transmitting an indication of the second beam having a highest receive strength, and refining at least one of the first or second spatial colocation parameters.

Abstract: Aspects of the present disclosure relate to techniques that may enhance radio link failure (RLF) procedures. In some cases, a UE may perform radio link monitoring (RLM) based on reference signals (RS) transmitted using a first set of beams, perform beam failure recovery (BFR) monitoring based on transmissions using a second set of beams, and adjust one or more radio link failure (RLF) parameters based on both the RLM monitoring and the BFR monitoring.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to sending and monitoring for a decoding candidate. Certain aspects provide a method for decoding information sent via a wireless transmission. The method generally includes receiving an indication of an association between a first decoding candidate and a second decoding candidate, monitoring the first decoding candidate in a search space of a first set of resources, the first decoding candidate received from a wireless node, and monitoring the second decoding candidate in a search space of a second set of resources, the second decoding candidate received from the wireless node, wherein the monitoring of the second decoding candidate is based on the association between the first and second decoding candidates.

Abstract: A base station may maintain multiple beam pair links, with one being actively used for communication. The active beam pair may become blocked. Accordingly, it may be necessary to switch to another beam pair. The apparatus may be an apparatus for wireless communication. The apparatus for wireless communication may include a memory and at least one processor coupled to the memory. The at least one processor is configured to determine a set of active beam pairs including at least a first beam pair and a second beam pair and select the first beam pair. The at least one processor is also configured to predict that the first beam pair is blocked, the prediction based on an expiration of a timer and sweep through the set of active beam pairs based on predicting that the first beam pair is blocked.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for data transmission in synchronization slots. A method for use by a base station for data transmission in synchronization slots includes transmitting a synchronization signal (SS) burst, wherein different SS blocks of the burst are transmitted using different transmit beams and performing frequency division multiplexing (FDM) or time division multiplexing (TDM) to include one or more other types of signals that need to be multicast and are also transmitted using the different transmit beams.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may determine a signal configuration for transmitting a tracking reference signal (TRS) to a user equipment (UE). The signal configuration may identify a subset of locations, of a set of locations included in a transmission window, that is to be used to transmit the TRS, and the signal configuration may be selected to assist the UE with one or more measurements. The apparatus may transmit, based at least in part on the signal configuration, the TRS in the subset of locations. Numerous other aspects are provided.

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 generally relate to wireless communications and, more particularly, to methods and apparatus for code rate selection for control channels. An exemplary method generally includes selecting, from a set of code rates, a code rate to be used to encode a stream of bits using a polar code, based on at least one of a downlink control channel aggregation size, an uplink control channel assignment, or a payload size of the stream of bits, encoding the stream of bits using the polar code and the selected code rate, and transmitting the encoded stream of bits.
