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.

Abstract: Methods, systems, and devices for wireless communication are described. A method at a user equipment (UE) includes receiving signaling that indicates a carrier aggregation (CA) configuration (having carriers configured for UL and downlink (DL) data transmissions) and an auxiliary uplink (UL) configuration (having carriers configured for UL reference signal transmissions). The method also includes receiving a resource assignment on a DL carrier of the CA configuration, and transmitting an aperiodic sounding reference signal (A-SRS) using the one or more carriers of the auxiliary UL configuration based at least in part on the received resource assignment. Another method is performed by a UE having a CA configuration and an A-SRS configuration, including receiving a resource assignment on a DL carrier in the CA configuration, detecting a trigger for transmitting an A-SRS, determining UL resources of the A-SRS configuration for transmitting the A-SRS, and transmitting the A-SRS on the determined UL resources.

Abstract: Methods and apparatuses for adaptive subcarrier spacing in wireless communication networks are described. For example, the described aspects include transmitting, from the UE to a network entity, a first PRACH transmission with a first subcarrier spacing; determining, by the UE, that the first PRACH transmission to the network entity is not successful; and transmitting, from the UE, a second PRACH transmission with a second subcarrier spacing in response to determining that the first PRACH transmission is not successful, wherein the first subcarrier spacing is different from the second subcarrier spacing.

Abstract: A wireless entity, such as a user equipment (UE) or transmission reception point (TRP), receives and processes aggregated positioning reference signals (PRS) to increase the effective PRS bandwidth, thereby increasing positioning accuracy, such as time of arrival measurements. An aggregated PRS includes one or more PRS components that are transmitted from a same transmitting entity. Each PRS component may be, e.g., a separate PRS resource associated with a contiguous frequency-domain bandwidth or may be, e.g., a plurality of frequency-domain bandwidths spanned by a single PRS resource. PRS components of an aggregated PRS that are unpunctured, e.g., do not collide with higher priority signals, are aligned in time domain, and are configured with common constraints are processed jointly assuming that the PRS components are transmitted from a same antenna port, thereby increasing the effective PRS bandwidth.

Abstract: Certain aspects of the present disclosure provide techniques for aperiodic channel state information (A-CSI) feedback scheduling for cross-carriers. Certain aspects provide a method for wireless communication. The method generally includes receiving on a first component carrier (CC) signaling indicating an aperiodic channel state information (CSI) report request for a plurality of CCs; determining schedules for at least CSI reference signal (CSI-RS) transmissions on the CCs based on the received signaling; monitoring CSI-RS transmissions on the CCs according to the determined schedules; and reporting CSI feedback based on CSI-RS measurements of the CSI-RS transmissions.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive multiple uplink grants that schedule uplink transmissions for two different radio access technologies (RATs) during overlapping time resources. The UE may adjust the power for one of the uplink transmissions based on the temporal proximity of the second received uplink grant relative to the first uplink transmission. The UE may adjust the power of the uplink transmission by partially or completely reducing its power.

Abstract: Wireless communication devices, systems, and methods related to mechanisms to implement PUCCH resource configuration for two-step RACH for subsequent HARQ messaging. After a UE transmits msgA to a BS, the BS responds with msgB including a PUCCH resource indicator in a DCI of PDCCH, or a PUCCH resource indicator in PDSCH. The UE attempts to decode PDCCH or PDSCH, respectively. Upon decoding, the UE will use the configuration identified by the resource indicator. With the PUCCH resource configuration information, the UE signals a HARQ message.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently signaling configurations of physical resources and transmission parameters to a user equipment (UE) for small data transmissions (for example, data transmissions in an inactive or idle state). A base station may broadcast or multicast downlink control information (DCI) in one or more control channels that schedules data transmissions in a set of data channels. The base station may then multicast one or more configurations in each of the data channels, and a UE may decode one of the data channels to determine a configuration for a small data transmission. Because the configurations may be transmitted in the data channels in addition to system information or paging information, a base station may have access to sufficient resources to provide suitable configurations to a UE for communications in an inactive or idle state.

Abstract: In some aspects, the SIB1 message is transmitted in a subframe 0 and a subframe 5 of alternating radio frames of the non-anchor carrier. In some aspects, the SIB1 message is transmitted in a subframe 0 of alternating radio frames of the anchor carrier. In some aspects, the frequency domain location parameter is associated with a physical resource block offset relative to a center frequency, and the anchor carrier is in a first frequency range greater than the center frequency by the physical resource block offset and the non-anchor carrier is in a second frequency range less than the center frequency by the physical resource block offset, or the non-anchor carrier is in the first frequency range greater than the center frequency by the physical resource block offset and the anchor carrier is in the second frequency.
