Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to random access channel (RACH) procedures in deployments where a RACH transmission may be sent on different UL carriers. An exemplary method performed by a base station includes receiving a random access (RA) preamble on a first component carrier (CC) of a plurality of CCs including at least one uplink (UL) CC and at least one supplemental uplink (SUL) CC and transmitting a response to the RA preamble, wherein the response indicates the first CC.

Abstract: Certain aspects of the present disclosure provide techniques for multiplexing channel state information (CSI) reference signals (CSI-RSs) and synchronization signals in wireless communications systems operating according to new radio (NR), e.g., 5th generation (5G), techniques. An exemplary method includes sampling subcarriers of a synchronization signal (SS) block based on a frequency density of channel state information (CSI) reference signals (CSI-RSs) multiplexed in a symbol period with the SS block, and performing at least one of: measuring at least one of reference signal received power (RSRP) or CSI, based on the sampled subcarriers and the CSI-RSs, or reporting at least one of the RSRP or the CSI, based on the sampled subcarriers and the CSI-RSs.

Abstract: The present application relates to slot format indicator signaling in wireless communication systems. For example, a network entity may configure a slot format to include one or more symbol partitions and a transmission assignment for each of the one or more symbol partitions, and communicate with to at least one UE according to the configured slot format. In another example, a UE may configure at least one slot format according to at least one of a semi-static configuration via a broadcast or unicast transmission, or a dynamic configuration via a group common physical downlink control channel (GC-PDCCH), and communicate with the network entity according to the slot format.

Abstract: A method and apparatus for downlink and uplink control management of component carriers during carrier aggregation in a new radio wireless communication system is disclosed. For example, the method and apparatus include receiving, at a user equipment (UE), a slot format indicator in at least one slot of at least one component carrier of a plurality of component carriers from a network entity, where the at least one component carrier includes a group common Physical Downlink Control Channel (PDCCH), the slot format indicator within the group common PDCCH indicating at least slot structure information for one or more other component carriers from the plurality of component carriers; and communicating, with the network entity, using the at least slot structure information for the one more other component carriers.

Abstract: The present disclosure relates to signaling information in physical broadcast channel (PBCH) demodulation reference signals (DMRS). In one example, a network entity may transmit the signaling information carried by a DMRS in one or more resource elements of physical broadcast channel (PBCH) symbols within a bandwidth of a primary synchronization signal and a secondary synchronization signal of a synchronization signal block. In another example, a user equipment (UE) may receive the signaling information carried by the DMRS within one or more resource elements of PBCH symbols within a bandwidth of a primary synchronization signal and a secondary synchronization signal of a synchronization signal block on a broadcast channel from the network entity.

Abstract: A method and apparatus for enhancing channel estimation by using a binary tree based PDCCH search space in a new radio wireless communication system is disclosed. For example, a UE may identify an aggregation level profile having an aggregation level value for one or more aggregation levels, wherein each aggregation level corresponds to a respective number of resources to use for decoding a PDCCH, determine one or more decoding candidates for the UE from among a plurality of available decoding candidates defined as nodes in a binary tree for a search space based on the aggregation level profile, determine respective CCEs corresponding to each of the one or more decoding candidates, each respective CCE including one or more REGs, and performing channel estimation for each of the respective CCEs for use in demodulating and decoding downlink control information for the UE in the PDCCH.

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: 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
