    Abstract: In a wireless network, a frame structure may include a padding duration at the start of every half subframe to ensure that an integer number of symbols fit within a duration of the half subframe. In some aspects, to avoid wasting time domain resources, the padding duration may be utilized for other purposes. For example, because a single carrier waveform is not bound to a fixed Fast Fourier Transform size, a wireless node may use the padding duration to transmit a single carrier symbol that has a shorter length than a full symbol associated with a subcarrier spacing. Additionally, or alternatively, in cases where a wireless node is configured to transmit or receive a signal in a first symbol of a half subframe that is associated with a different power level than a preceding symbol, the padding duration may be used to adapt a transmit power or a receive gain.

    Abstract: Methods, systems, and devices for wireless communications provide techniques for multiplexing, in a frequency domain, a synchronization signal block (SSB) and a control resource set (CORESET) to form a multiplexed block that is transmitted using a set of symbols. A base station may transmit multiple multiplexed blocks using multiple different beams with a switching gap provided between each multiplexed block that allows for switching of radio frequency (RF) components between different beams. The switching gap is longer than a duration of a cyclic prefix (CP) that is associated with each symbol of the set of symbols of each multiplexed block. Within one or more of the multiplexed blocks, an associated SSB may use a different waveform than the CORESET. The multiplexed blocks may use a common reference signal for both the SSB and CORESET.

    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may communicate according to a combined cyclic prefix and guard interval-based waveform format. The base station may transmit control signaling to the UE. The control signaling may indicate a slot configuration. The UE may identify a format of a slot including a set of symbols based on the slot configuration. The format may indicate that a first portion of a first symbol of the set of symbols includes at least two cyclic prefixes and a second portion of the first symbol includes a guard interval. The UE and the base station may perform wireless communications during the first symbol in accordance with the format.

    Abstract: Methods, systems, and devices for wireless communications are described. Wireless communications systems may support implementation of narrow bandwidth parts (NBWPs). For example, a NBWP may be established over a reduced bandwidth to support user equipment (UEs) with reduced complexity features (e.g., such as UEs with reduced bandwidth capabilities). Wireless communications systems may provide for UE transitioning to a NBWP (e.g., after initial cell search), as well as for UE transitioning amongst NBWPs (e.g., subsequent transitions to other NBWPs after an initial transition to a NBWP after initial cell search). For example, a UE may initially transition to a NBWP (e.g., transition to monitor the NBWP for reference signals or to utilize the NBWP for uplink/downlink communications) to support reduced bandwidth capabilities of the UE. Subsequently, the UE may transition amongst other NBWPs for network load balancing, UE frequency hopping gain, etc.

    Abstract: Methods, systems, and devices for wireless communications are described. Devices in a wireless communications system may support different configurations to support intra-symbol multiplexing for communications between the devices using a single carrier waveform. For example, the different configurations may include symbol level cyclic prefixes, device-specific or channel-specific cyclic prefixes, device-specific or channel-specific guard intervals, or a combination thereof to support the intra-symbol multiplexing. That is, the cyclic prefixes or guard intervals may separate different fractions of a symbol, such that individual signals communicated in each of the different fractions do not leak into a subsequent fraction to cause interference. In some implementations, the cyclic prefixes or guard intervals may be enabled for a subset of devices or channels. A configuration for this intra-symbol multiplexing with device-specific or channel-specific cyclic prefixes or guard intervals may be signaled in a control message to the corresponding devices.

    Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a base station may transmit, to a user equipment (UE), an indication of a dynamic switch between slot formats. The base station and the UE may communicate first data in one or more first slots according to a first slot format. The first slot format may be a first cyclic prefix-based or guard interval-based slot format. The base station may transmit control signaling to the UE to indicate a second slot format different from the first slot format. The second slot format may be a second cyclic prefix-based or guard interval-based slot format. The UE and the base station may switch to communicating second data in one or more second slots in accordance with the second slot format based on the control signaling.
