Abstract: Certain aspects of the present disclosure provide techniques for rate matching PDSCH around NZP CSI RS transmissions in multi-TRP scenarios. In some cases, a network entity may signal a rate matching behavior to a user equipment (UE) for processing a physical downlink shared channel (PDSCH) configured with a first quasi co-location association and transmitted from a first transmission reception point (TRP) that potentially collides with one or more types of non-zero power (NZP) reference signals (RS) configured with a second quasi co-location association and transmitted from a second TRP using one or more resource sets.

Abstract: Methods, systems, and devices for wireless communications are described. A transmission reception point (TRP) may determine a configuration for downlink transmission of group-common control information associated with a plurality of TRPs. The TRP may identify a set of downlink resources allocated for transmission of the group-common control information. A user equipment (UE) may receive the configuration from at least one TRP of the plurality of TRPs. The UE may monitor downlink resources for reception of the group-common information based on the configuration. The TRP may transmit, and the UE may receive, the group-common control information over the downlink resources. The group-common control information may indicate communication parameters for communications between the UE and at least one TRP.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that uplink communications are to be performed between the UE and a first cell group associated with a first radio access technology (RAT) and between the UE and a second cell group associated with a second RAT. The UE may determine that the UE is configured for power sharing for the uplink communications with the first cell group associated with the first RAT and the second cell group associated with the second RAT. The UE may calculate, based at least in part on the power sharing and the uplink communications, a power reduction factor for the uplink communications between the UE and the second cell group. The UE may perform the uplink communications with the first cell group and selectively perform the uplink communications with the second cell group.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a random access (RACH) procedure based on a selected synchronization signal block (SSB). During this RACH procedure, a base station may transmit physical downlink control channel (PDCCH) messages for UE RACH message handling. To receive PDCCH signaling for RACH Messages 2, 3, or 4 (Msg 2/3/4), the UE may identify a set of time resources used by the base station for transmitting SSBs that are not quasi-co-located (QCL) with the selected SSB. The UE may identify a Msg 2/3/4 search space that does not overlap with this identified set of resources, and may monitor this identified search space. The search space may correspond to a modified remaining minimum system information (RMSI) search space indicated by the base station, or a valid RMSI search space not indicated by the base station.

Abstract: Methods, systems, and devices for wireless communication are described. In some cases, due to blind decoding and channel estimation (CE) limits, one or more user equipment (UE) specific search sets may be pruned for blind decoding and/or CE purposes. For instance, after hashing a set of common decoding candidates to control channel elements (CCEs) within the control region, the UE specific search sets may be pruned so as to conform to the blind decode limitation, since a common search space has already occupied a portion of the total blind decode limit. Following pruning, the UE may hash the sets of UE-specific decoding candidates associated with the one or more UE specific search sets to CCEs within the control region. The UE may further prune UE specific search sets, based on CE limits, while reusing CE for overlapping hashed locations.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a remaining minimum system information control resource set (RMSI CORESET) monitoring configuration based at least in part on information received by the UE in a first frame; and monitor, during a second frame and based at least in part on the RMSI CORESET monitoring configuration, for an RMSI CORESET based at least in part on a synchronization signal block (SSB), associated with the RMSI CORESET, that is received in the first frame.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine that a triggering event associated with a user equipment (UE) has occurred. The UE may receive, based at least in part on an occurrence of a triggering event associated with the UE, a trigger signal that identifies resources to be used for transmission of an aperiodic tracking reference signal (TRS). The UE may receive the aperiodic TRS based at least in part on the trigger signal and the identified resources. The UE may perform at least one of a tracking function, or a synchronization function, or an alignment function, or a combination thereof, in response to the occurrence of the triggering event and based at least in part on the aperiodic TRS.

Abstract: RESUMEN Se describen métodos, sistemas y dispositivos para comunicaciones inalámbricas. Un dispositivo inalámbrico puede recibir información de control de enlace descendente que corresponde a una transmisión de un bloque de transporte a través de una pluralidad de intervalos de tiempo de transmisión (TTI). El dispositivo inalámbrico puede identificar una secuencia de versión de redundancia para el bloque de transporte. La versión de redundancia puede ser una secuencia predefinida o puede estar configurada por señalización de capa superior con base en un criterio de secuencia. El dispositivo inalámbrico puede transmitir o recibir una pluralidad de versiones de redundancia del bloque de transporte en la pluralidad de TTI con base, al menos en parte, en la secuencia de versión de redundancia. En algunos ejemplos, la pluralidad de versiones de redundancia puede estar determinada con base, al menos en parte, en una versión de redundancia inicial identificada por otro dispositivo inalámbrico.

Abstract: Certain aspects of the present disclosure provide techniques for performing, by a user equipment (UE), radio link monitoring based on discontinuous reception mode operation of the UE. Certain aspects provide a method for wireless communication. The method generally includes operating, at a user equipment (UE), in a discontinuous reception (DRX) mode of operation. The method further includes evaluating, by the UE, link quality between the UE and a base station (BS) at least once every time period, wherein the time period is based on a length of a DRX cycle of the UE operating in the DRX mode of operation and a reference signal (RS) period, wherein the BS is configured to transmit RS periodically every RS period.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to efficient data scheduling in systems having a supplemental uplink carrier (SUL) configured. In some aspects, a method for wireless communications by a user equipment (UE) is provided. The UE receives signaling configuring the UE for uplink control channel transmission on a primary uplink carrier (PUL) or a SUL. The SUL is an uplink carrier not paired to a downlink carrier. The UE monitors in at least one search space for downlink control information (DCI) scheduling the UE for uplink data transmission to a cell on the PUL or the SUL. The UE sends one or more uplink data transmissions to the cell on the primary uplink carrier or the supplemental uplink carrier based on the DCI.
