Abstract: Systems and methods in which one or more wireless communication stations implement duplex-mode remediation to facilitate the signal communication when an issue with respect to self-interference is identified are described. Duplex-mode remediation may be implemented for various communication scenarios, such as for random access phase communications, for communications having different priorities, etc. A wireless communication station may implement one or more changes with respect to the full duplex operation of the wireless communication station based upon determining that an issue with respect to self-interference may be, or is being, experienced, such as to provide for a wireless communication station operating in an in-band full duplex mode to increase interference cancellation and/or to fall back to a sub-band full duplex mode or a half duplex mode, to provide for a wireless communication station operating in a sub-band full duplex mode to increase interference cancellation and/or to fall back to a half duplex mode.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, to a user equipment (UE), a control message in a first control channel occasion associated with a first quasi-colocation (QCL) property, the control message indicating a transmission of a data message within a threshold time period. The UE may receive, from the base station, an indication to skip monitoring of a second control channel occasion within the threshold time period and may receive the data message in accordance with a second QCL property, or drop reception of the data message, based on the indication. Additionally, or alternatively, the base station may transmit a message indicating a unified transmission configuration indicator (TCI) state associated with the second QCL property, and the UE may receive the data message in accordance with the second QCL property based on the unified TCI state.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a signal indicating a wakeup opportunity associated with receiving one or more messages from an application and may identify a mapping between an attribute of the signal and an identifier associated with the application. The UE may determine a wakeup procedure in response to receiving the signal based on the mapping between the attribute of the signal and the identifier associated with the application.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems (e.g., non-orthogonal multiple access (NOMA) systems), a base station may serve a large number of user equipments (UEs) on the uplink. To improve detectability for these uplink transmissions (e.g., if reference signals are not available for the transmissions), the UEs may implement parallel transmissions of preambles with uplink data. A UE may split the uplink data into one or more data layers, and may select one or more preamble layers to transmit superposed with the data layers. These preambles may be sequences known to both the UE and the base station to aid in detectability. The UE may assign different signature sequences to each of these layers based on cross-correlation values (e.g., assigning sequences with higher cross-correlation values to the data layers for improved detectability), and may scramble the layers into a single shared signal for transmission.

Abstract: Methods, systems, and devices for wireless communications are described that relate to a two-step random access procedure. Generally, the described techniques allow different configurations for a first message of a random access procedure depending on a connected-state of the user equipment (UE) performing the random access procedure. A base station may transmit configuration information to the UE and the UE may use the configuration information to determine resources, coding, block size, or other factors for transmitting the first message based on the radio resource control (RRC) connected state of the UE. The UE may then monitor for a random access response from the base station based on the first message from the UE.

Abstract: This disclosure describes methods, devices, and systems for techniques related to random access procedures, such as a two-step random access procedure. Generally, the described techniques support physical uplink shared channel (PUSCH) occasion (PO) aggregation in random access procedures, including aggregation configurations and communication schemes that support enhanced data transmissions, such as small data transmissions, in random access procedures. In some examples, the described techniques may include aggregating POs in a time domain, or a frequency domain, or both. A device, such as a user equipment (UE) may aggregate, in one or more of a time domain or a frequency domain, multiple POs of a set of POs, and transmit, to a device such as a base station, a random access payload of a random access message on a PUSCH using time and frequency resources of the aggregated multiple POs.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a user equipment (UE) may be configured to receive a control message scheduling a multicast transmission, and the UE may identify an open loop power control parameter for transmitting acknowledgment feedback responsive to the multicast transmission. The identification of the open loop power control parameter may be based on the transmission being multicast to a plurality of UEs, and in some cases a UE may identify an open loop power control parameter that is different than an open loop power control parameter associated with feedback responsive to unicast transmissions. In various examples, open loop power control parameters may correspond to respective feedback resources (e.g., according to a configuration for a set of open loop power control parameters), or to respective physical resource indicators (e.g., as signaled in downlink control information).

Abstract: Certain aspects of the present disclosure provide techniques for indicating carrier aggregation capabilities. An example method generally includes signaling, to a base station (BS), carrier aggregation capability information indicating a capability for performing separate operations concurrently on a plurality of component carriers; receiving a carrier aggregation configuration indicating component carriers designated for the separate operations; and receiving or transmitting transmissions based on the carrier aggregation configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to bundle or not bundle demodulation reference signals (DMRS) of multiple downlink data transmissions using an indication from a base station. The indication may be transmitted via control signaling, such as downlink control information (DCI) from the base station to the UE. For example, a bit of the DCI may be used to dynamically indicate a current precoding in relation to a preceding precoding. For example, the bit may indicate if the current precoding is the same as a previous precoding (e.g., UE may bundle the DMRS), or the bit may indicate that the current precoding is different than the previous precoding (e.g., UE may not bundle DMRS).

Abstract: Methods, systems, and devices for wireless communications are described. A set of reference signal resources that are configured for sounding reference signal transmissions may be shared among user equipments (UEs) that are enabled to receive multicast communications. Each of the shared set of reference signal resources may be associated with set(s) of channel state information. UEs may measure a multicast channel to determine channel state information for the multicast channel and transmit sounding reference signals over one of the shared reference signal resources that is associated with the set of channel state information determined by the UE. A base station that receives the sounding reference signal may transmit a subsequent multicast transmission for the UEs using transmission parameters that are adapted for the set(s) of channel state information associated with the occupied sounding reference signal resource.
