Abstract: Aspects described herein relate to managing and/or configuring, for a user equipment (UE), unicast and/or multicast radio bearers for unicast and/or multicast cells based on measurement reports generated by the UE.

Abstract: Aspects are provided allowing a first base station to distinguish between cross-link interference and remote interference caused to a second base station and to apply different mitigation mechanisms based on the type of interference. A UE receives from a second base station a reference signal based on a reference signal identifier that indicates a location of the second base station that is experiencing interference from the first base station. The UE sends to the first base station an indication of the reference signal received from the second base station. The first base station receives from the UE the indication of the reference signal from the second base station based on the reference signal identifier. The first base station applies a mitigation mechanism based on whether the reference signal identifier indicates that the second base station is a remote base station or a neighbor base station.

Particularly, in order to compensate for the loss of downlink coverage and improve load balancing, aspects of the present disclosure configure the UE to perform random-access channel (RACH), a procedure that is a shared channel used by wireless terminals to access the mobile network, on the anchor carrier in time division duplex (TDD) band and after initial access, the UE may be configured to switch to SDL to receive subsequent downlink signals.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a beam used for communicating with a network entity, the beam associated with multiple bandwidth parts (BWPs) including a reference BWP with a first frequency. The UE may receive a BWP configuration from the network entity, the BWP configuration based on changing a frequency for at least one BWP of the multiple BWPs form the first frequency to a second frequency. Additionally or alternatively, the UE may identify a timing threshold associated with a BWP switching operation for multiple BWPs associated with the beam.

Abstract: Wireless communications systems and methods related to receiving uplink carrier aggregation transmit chain switch scheduling. A UE may be configured for both inter-band and intra-band CA. When the UE receives uplink scheduling information for UL CA, the UE may analyze multiple component carriers in a frequency band, instead of just one component carrier per frequency band. The UE may derive antenna port configurations from the scheduling information, and map the antenna port configurations to an RF chain case. The RF chain case identifies an RF chain allocation configuration. Once mapped, the UE may determine whether an uplink RF chain switch should occur to accommodate the new RF chain allocation configuration. If different from the current RF chain allocation configuration, the switch is made. Further, the UE may add uplink transmission preparation time in response to the analysis and change if necessary.

Abstract: A base station (BS) may determine (estimate) a preparation time for at least one uplink (UL) transmission by a user equipment (UE) on at least one radio frequency (RF) carrier. The BS may determine the preparation time so that the BS will send a grant for the at least one transmission to the UE a sufficient amount of time (based on the estimated preparation time) before the at least one transmission is scheduled to occur to enable the UE to conduct the at least one UL transmission on a selected one of the RF carriers or on both RF carriers. The BS may select the longest preparation time from the preparation times of different RF carriers. The BS may select the subcarrier spacing (SCS) index from the SCS indexes for different RF carriers that provides a longer preparation time. The BS may add a defined value to a preparation time.

The apparatus receives, from the wireless communication device, channel state information in response to the one or more reference signals. The apparatus determines a channel estimate for the OTA space based on the received channel state information.

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.
