Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently transmitting data and control information in a first RACH message to a base station as part of a two-step RACH procedure. In particular, rather than or in addition to transmitting data and control information in a physical uplink shared channel (PUSCH) in the first RACH message, a user equipment (UE) may transmit the data and control information along with a RACH preamble in a RACH occasion in the first RACH message (e.g., when the number of bytes of data or control information to be transmitted is low). Using these techniques, in some instances, the UE may transmit the data and control information in a first RACH message without transmitting the PUSCH, and the overhead associated with transmitting the PUSCH may be eliminated.

Abstract: Certain aspects of the present disclosure provide techniques performing measurement reporting. One aspect is a method for performing measurement reporting at a user equipment, including: receiving, from a master node, a message comprising a measurement configuration for a secondary node; entering an inactive state; performing measurements according to the measurement configuration for the secondary node immediately after entering the inactive state; generating a measurement report based on the measurements; transmitting, to the master node, an RRC resume request message; receiving, from the master node, an RRC resume message comprising a request for measurement reporting; and transmitting, to the master node, an RRC resume complete message comprising the measurement report; and receiving data from the secondary node.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for performing minimization of drive test (MDT) operations. For example, certain aspects provide a method for wireless communication. The method generally includes receiving, at a radio access network (RAN), a measurement configuration to start a trace of a user-equipment (UE), determining a transition of the UE to an inactive state, and sending one or more messages to coordinate the trace of the UE or indicate that the trace has failed in response to the determination.

Abstract: Methods, systems, and devices for wireless communications are described. A first base station may identify that the first base station is a secondary node for a user equipment (UE) operating in a dual connectivity deployment, where the UE is in a radio resource control (RRC) inactive state. The first base station may receive, from the UE, a request to resume communications with the first base station and a second base station that is a master node in the dual connectivity deployment. The first base station may verify the UE using an access stratum context associated with the UE, and resume communications with the UE based at least in part on the request and the access stratum context. The first base station may resume communications as a secondary node or as a master node. In some cases, the UE may resume communications without entering an RRC idle state.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (HE) may support beam management to determine beams for communicating with a base station, measure characteristics of the beams, and periodically report the measurements to the base station. The beam management may include a beam failure recover), procedure, where the UE detects and resolves a beam failure with the base station. Additionally, the UE may perform radio link monitoring (RLM) on a set of reference signals configured by the base station to determine if a radio link (e.g, beamformed transmission) is synchronized or not between the UE and base station. In some cases, these RLM reference signals (RLM-RSs) may be reconfigured, where the reconfiguration may be based on the periodic beam measurement reports for beam management, a beam monitoring event trigger, a beam failure recovery, or a combination thereof.

Abstract: An apparatus for wireless communication, including a memory and at least one processor coupled to the memory. The at least one processor is configured to receive a pre-allocation resource for a target cell via a handover command and transmit a physical layer acknowledgment based on a target cell downlink packet. The at least one processor is also configured to receive an indication for a communication with the target cell in response to the physical layer acknowledgement and access the target cell using the pre-allocated resource based on the indication for the communication with the target cell.

Abstract: Techniques for co-existence between wireless Radio Access Technologies (RATs) are disclosed. During an active period of a Discontinuous Transmission (DTX) communication pattern, a first signal may be transmitted during a first subframe and a second signal may be transmitted during a second subframe, while during an inactive period the first signal may be transmitted during the first subframe and the second signal may be omitted during the second subframe. Retransmission of one or more packets may take place over a subset of less than all retransmission opportunities based on the DTX communication pattern. A Secondary Cell (SCell) may be reconfigured as the Primary Cell (PCell) and the PCell may be reconfigured as the SCell for one or more access terminals based on a load balancing condition or a channel selection condition.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for linear precoding in full-dimensional MIMO (FD-MIMO) systems. According to aspects, an eNB may compress a larger number of antenna elements to a smaller number of antenna ports. The eNB may use a port precoding matrix to transmit reference signals to a UE, receive feedback regarding CSI based on the reference signals, and transmit data to the UE, based on a mapping of multiple data layers and mapping of antenna ports to the physical antenna elements. Further, aspects include performing elevation beamforming by dynamically forming one or more vertical sectors based on UE feedback in the elevation domain.

Abstract: Methods, systems, and devices for wireless communication are described. A central unit (CU) of a network entity may receive, from a first user equipment (UE) via a second UE, a connection setup request message for a first UE. The CU may establish UE context information for the first UE at an adaptation layer of the CU, the CE context information based at least in part on communications between the first UE and the network entity via the second UE. The CU may transmit, to a distributed unit (DU) associated with the CU, an indication of a relaying configuration for the first UE connecting to the network entity via the second UE, the relaying configuration comprising multiplexing and forwarding information for a connection between the second UE the DU. The CU may communicate with the first UE via the second UE according to the UE context information and the relaying configuration.
