Abstract: Methods, systems, and devices are described for providing periodic CSI reports and/or aperiodic CSI reports to provide CSI for both anchor and non-anchor TDD subframes in eIMTA. Periodic CSI reports may be provided based on a reference configuration, and aperiodic CSI reports may be provided based on a time of reception of a CSI request and a reference configuration. A UE may determine to report anchor or non-anchor CSI through explicit or implicit signaling. Aperiodic CSI may be used for transmission of anchor subframe CSI reports and periodic CSI may be used for transmission of non-anchor subframe CSI reports, or aperiodic CSI may be used for transmission of non-anchor subframe CSI reports and periodic CSI may be used for transmission of anchor subframe CSI reports. A determination of the reference subframe for aperiodic CSI estimation may be based on a time of receipt of an aperiodic CSI request.

Abstract: This disclosure provides systems, methods, and apparatuses for low latency handover between secondary nodes (SNs). In one aspect, a user equipment (UE) may receive a configuration for a plurality of SNs, receive a command to communicate via an SN of the plurality of the SNs, and determine a handover procedure that is to be used to establish a connection with the SN. The handover procedure may be a random access channel (RACH)-less or a two-step RACH procedure and is determined to be used based on a determination that uplink time synchronization is established with the SN.

Abstract: Aspects of the present disclosure describe managing beams in wireless communications. A beam management event configuration indicating a type of at least one beam to measure in determining occurrence of a trigger condition for a beam management event can be received. A parameter of a signal received from one or more nodes can be measured, where the signal corresponds to the type of the at least one beam. The occurrence of the trigger condition for the beam management event can be determined based on the parameter of the signal. An indication of the occurrence of the trigger condition can be reported to the one or more nodes or a different node.

Abstract: Certain aspects of the present disclosure provide techniques for a floating synchronization signal block measurement timing configuration (SMTC) for SSB-based radio resource management (RRM) in asynchronous networks, such as new radio (NR). A base station (BS) determines a floating SMTC for measurement of a target cell and provides the floating SMTC to at least one user equipment (UE) in the serving cell, wherein the target cell and the serving cell are asynchronous. The BS determines a measurement gap that covers the floating SMTC. The UE monitors in the measurement gap for a SSB transmission of the target cell based on the floating SMTC.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay user equipment (UE) may establish a sidelink unicast link with a remote UE via a sidelink signaling interface. The relay UE may identify configuration information for an adaptation layer of the sidelink signaling interface, the configuration information including at least one of: a remote UE identifier associated with the sidelink unicast link for a relay service, bearer identifier information identifying one or more bearers between the remote UE and a network entity for the relay service, a radio link control (RLC) channel mapping between a bearer identifier and one or more RLC channels, or data routing information associated with the relay service. The relay UE may relay communications between the remote UE and the network entity based at least in part on the configuration information. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure relate to communication systems, and more particularly, to system information acquisition over bandwidth parts (BWPs) in communications system operating according to new radio (NR) technologies. In an exemplary method, a user equipment (UE) receives system information (SI) via a transmission in a downlink (DL) bandwidth part (BWP) of a system bandwidth and transmits, to a serving base station (BS) and in response to receiving the SI, an indication that the UE has completed SI acquisition.

Abstract: Techniques described provide for a wireless network to establish and implement periodic and aperiodic sidelink gaps. One implementation may include transmitting, by a first user equipment (UE), a sidelink configuration message. The sidelink configuration message may indicate a capability of the first UE to support a sidelink periodic gap and a sidelink aperiodic gap. A message may be received by the first UE indicating whether the first UE is allowed to request a gap according to one or more of the indicated capabilities. The first UE may transmit a sidelink information message comprising an absolute radio frequency channel number (AR-FCN) and an associated gap list. An RRC reconfiguration message may also be received by the first UE having and updated gap list. Other aspects and features are also claimed and described.

Abstract: A wireless device may receive a first synchronization signal block (SSB) in a radio frequency band of a first cell of a neighbor base station, and report a physical cell identifier (PCI) for the first cell to a serving base station. The serving base station may identify, based on the PCI report, whether a radio frequency band of the first SSB is in or off a synchronization raster, and determine whether to instruct the UE to report a global cell identifier (CGI) for the neighbor base station (e.g., CGI for the neighbor cell) based on the identification. The wireless device may identify CGI based system information obtained from the neighbor cell, system information obtained from a master cell associated with the neighbor base station, system information obtained from CGI broadcast from the neighbor cell, or system information requested from the neighbor cell using dedicated resources, based on the instruction.
