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: 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: 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 of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a coreset of time and frequency resources within a control region of a coreset bandwidth. In one aspect, the coreset bandwidth may be based on a minimum bandwidth configuration associated with one or more UEs in a set of UEs. The apparatus may also transmit a PDCCH as a single-carrier waveform via the coreset of time and frequency resources. In one aspect, the PDCCH may be transmitted to each UE in the set of UEs using the coreset bandwidth.

Abstract: When a base station is capable of using multiple different types of waveforms for a downlink communication to a UE, the UE may waste processing resources attempting to receive and/or process the downlink communication. For example, the UE may cycle through various possible types of waveforms in an attempt to process the downlink communication. Techniques described herein use waveform signaling for downlink communications to notify the UE of a type of waveform being used for a downlink communication, thereby conserving UE resources (e.g., processing resources, memory resources, RF resources, and/or the like) that would otherwise be wasted attempting to process the downlink communication using multiple types of waveforms.

Abstract: Aspects of the disclosure relate to wireless communication networks having a capability of controlling the mapping of reference signals onto a carrier based on one or more Doppler parameters. A demodulation reference signal (DMRS) is mapped to a carrier according to a pattern based on one or more Doppler parameters, such as a Doppler frequency and/or a rate of change of channel conditions. In a further example, if an initial transmission of an information packet fails due to a high Doppler scenario, the probability of success of the retransmission may be improved by altering the DMRS configuration to account for the high Doppler scenario. Other aspects, examples, and features are also claimed and described.
