Abstract: A wireless communication system utilizes a synchronization signal block (SSB) structure to enable beam switching at higher sub carrier spacing (SCS) or uplink transmissions within an SSB. The SSB structure has a first SCS for an SSB transmission and a second SCS for a data transmission. The SSB structure is based on the first SCS and the second SCS, with the SSB structure including at least one gap between SSB symbols or between SSBs. The wireless communication system transmits or receives an SSB based on the SSB structure. A base station may transmit a downlink signal during the gap, for example, where the second SCS is much greater than the first SCS. A user equipment may transmit an uplink signal such as an acknowledgment during the at least one gap. The user equipment or the base station may perform analog beam switching during the at least one gap between SSBs.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for performing rate matching when resources for a physical downlink shared channel (PDSCH) overlap with resources of a control resource set (CORESET) in which a physical downlink control channel (PDCCH) that scheduled the PDSCH. As used herein, rate matching generally refers to the process of repeating or puncturing bits on a transport channel.

Abstract: Subcarrier spacing (SCS) for data may be adapted or dynamically configured based on the occurrence or presence of a synchronization signal block (SSB) transmission. For example, during a SSB transmission, the SCS of data may be automatically switched from some default data SCS to a second SCS (e.g., the SCS of the SSB) to allow for frequency division multiplexing (FDM) of data and SSB where the data and SSB use the same numerology. As such, communicating devices (e.g., a base station and a user equipment (UE)) may identify some location or configuration for a SSB, and may determine a second subcarrier spacing (e.g., a subcarrier spacing associated with the SSB) such that the SCS of data may be adapted to the second subcarrier spacing during the FDM of the SSB and the data. The SSB and data may thus be contemporaneously transmitted or received using the second SCS.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify control information to be transmitted, in a slot, to a user equipment (UE). The base station may determine a configuration for splitting a control resource set for the control information into a first component control resource set and a second component control resource set within a supported bandwidth of the UE. The first component control resource set may be frequency diverse and time diverse from the second component control resource set. The base station may transmit the configuration to the UE.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to a control resource set (coreset) for transmitting physical downlink control channels using a single-carrier waveform in communications systems operating according to new radio (NR) technologies. In an exemplary method, a base station may determine a first control resource set (coreset) of time and frequency resources within a control region of system bandwidth, to transmit a physical downlink control channel (PDCCH) to a user equipment (UE) and transmit the PDCCH to the UE as a single-carrier waveform via the first coreset of time and frequency resources.

Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example a first grant associated with the second DCI part is offset relative to a slot position of the second DCI part, whereas a second grant associated with the second DCI part is offset relative to the slot position to which the first grant is offset. In another aspect, two or more grants are grouped together, with the respective group being mapped to a PUCCH.

Abstract: Certain aspects of the present disclosure provide techniques for communication of downlink control information (DCI) piggybacked on a physical downlink shared channel (PDSCH) configured using semi persistent scheduling (SPS). A method that may be performed by a user equipment (UE) includes receiving a message having a configuration for semi persistent scheduling (SPS) of data channels, receiving an indication associated with at least one first downlink control information (DCI) for transmission in at least one of the data channels, and monitoring for the data channels in accordance with the configuration for SPS.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, in a control channel, a first grant identifying a first set of resources of a first data channel on which the UE is to monitor for one or more second grants, the first data channel being downlink. The UE may monitor the first set of resources in the first data channel for the one or more second grants, the one or more second grants identifying a second set of resources of a second data channel on which the UE is to perform data communications. The UE may transmit, based at least in part on the monitoring the first set of resources, a feedback message associated with receipt of the one or more second grants.
