Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect beam failure on a secondary cell (SCell), wherein the UE is configured with a primary cell (PCell) and the SCell for carrier aggregation with a base station; identify one or more resources for transmission of a beam failure recovery request based at least in part on detecting the beam failure, wherein the one or more resources are on one or more SCells configured for the UE; and transmit the beam failure recovery request to the base station using the one or more resources. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A serving cell may configure one or more neighbor cells to perform measurements on sounding reference signals (SRSs) received from a user equipment (UE). The serving cell and a subset of the one or more neighbor cells may then transmit data to the UE in a single frequency network (SFN) transmission based on the SRS measurements. For instance, the serving cell may determine whether to add each of the one or more neighbor cells to an SFN cell group for an SFN transmission to a UE based on measurements performed by each neighbor cell on SRSs received from the UE. A neighbor cell of the one or more neighbor cells may also determine which beam to use for an SFN transmission to a UE based on measurements performed by the neighbor cell on SRSs received from the UE.

Abstract: Systems, methods, and devices for wireless communication that support mechanisms for enabling sidelink demodulation reference signal (DMRS) bundling in a wireless communication system. In aspects, a transmitting user equipment (UE) may be configured for sidelink communication with a receiving UE, and a sidelink DMRS transmission may be determined to be transmitted from the transmitting UE to the receiving UE. In aspects, determining whether to enable bundling of the sidelink DMRS transmission from the transmitting UE to the receiving UE or not (e.g., whether to enable or to forego enabling bundling of the sidelink DMRS transmission) may be determined in accordance with various aspects of the present disclosure.

Abstract: Systems, methods, and apparatuses for performing a beam recovery procedure using a second CC are disclosed. A UE may perform a beam recovery procedure using two component carriers (CCs): for example, first component carrier may be a beam formed millimeter wave (MMW) carrier having a beam recovery procedure and second component carrier may be an assisting carrier such as a sub-6 GHz carrier or a different MMW carrier. In a first example, a UE may trigger beam recovery for first component carrier (on second component carrier), generate a beam measurement report, and transmit the beam report on resources allocated for uplink transmission on second component carrier. In a second example, a new scheduling request (SR) may be defined on first component carrier for second component carrier beam recovery. In a third example, RACH resources or procedures on second component carrier may be used to perform the beam recovery for first component carrier.

Abstract: Methods, systems, and devices for wireless communications are described in which spatial relations for one or more uplink reference signal transmissions, such as sounding reference signal (SRS) transmissions, may be configured and a particular spatial relation indicated in a medium access control (MAC) control element (CE). A base station may configure a pool of available spatial relations for use in SRS transmissions, and the MAC-CE may indicate which spatial relation of the set of available spatial relations is to be used. In other cases, the MAC-CE may provide all of the spatial relation information for an associated SRS transmission. The UE, responsive to receiving the MAC-CE, may transmit a SRS to the base station using the indicated spatial relation.
