Abstract: Certain aspects of the present disclosure provide techniques for 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, a radio resource control (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: Methods, systems, and devices for wireless communications are described. Examples may include receiving, at a user equipment (UE) a random access channel (RACH) configuration message from a base station, where the message indicates a channel metric (e.g., received signal strength indicator (RSSI), reference signal received power (RSRP), reference signal received quality (RSRQ), a signal-to-noise ratio (SNR), signal-to-interference-plus-noise ratio (SINR), or the like) and a threshold associated with the channel metric. The, UE may measure a reference signal (e.g., synchronization signal block (SSB), channel state information reference signal (CSI-RS), or the like) and select a RACH procedure based on comparing the measured channel metric to the threshold. For example, the UE may select a two-step RACH procedure if the measured channel metric satisfies the threshold specified in the configuration. In some cases, the UE may select a RACH procedure or a listen-before-talk (LBT) procedure based on a QoS parameter.

Abstract: A base station may configure a first node and at least one second node with an integrated access and backhaul (IAB) network with the multipath multi-hop transmission configuration. The first node and the at least one second node may communicate with the first node through a direct path and a multi-hop transmission including the base station. The first node and the at least one second node may detect transmission failure on the direct path and retransmit the data packet to the multi-hop transmission, on a set of physical resource blocks (PRBs) configured by the base station. The first node may transmit remote buffer state report (rBSR) to the base station, and the base station may configure the set of PRBs for retransmissions based on the rBSR.

Abstract: Inform a master node about the feasible of secondary node cells during resumption of dual connectivity may require a large message. Additionally, the message may need to be encrypted. A solution to overcome the size and security limitation is to report a short identifier (or index) which is only shared between the UE and the MN. Accordingly, an apparatus, e.g., a UE, may be configured to receive, from a master node, a configuration comprising a mapping of cell identities for a plurality of secondary cells for reporting SN measurements and transmitting an SN report comprising measurements for at least a subset of the plurality of secondary cells using the mapping of cell identities. The apparatus may be configured to receive, from a first master node, a configuration for MN-DC, enter an inactive state or an idle state, and resume a connected state with a second master node.

Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment (UE) may determine to perform a relay selection procedure and receive respective messages from one or more second UEs including one or more parameters for selecting a second UE to relay communications between the first UE and a network entity. The first UE may determine that respective parameters satisfy a threshold and select the second UE associated with the respective parameters. In some cases, the first UE may receive a control message prior to performing the relay selection procedure. The control message may include a configuration for modifying the communication path that includes an indication of one or more candidate UEs for relaying communications between the first UE and the network entity.

Abstract: This disclosure provides systems, methods, and apparatuses to enable a user equipment (UE) and a base station to improve reception of a random access response (RAR) by the UE in an unlicensed spectrum. A network may define a procedure for calculating a random access radio network temporary identifier (RA-RNTI) specific to unlicensed spectrum based on an extended RAR window. The calculation procedure may allow UEs transmitting in the window to calculate a unique RA-RNTI and identify a RAR addressed to the UE using the unique RA-RNTI. Additionally, or alternatively, a base station may transmit a RAR including timing information associated with a corresponding random access request. Accordingly, a UE may receive the RAR and compare the timing information with its own random access request in order to determine whether the RAR is addressed to the UE. Additionally, a UE may monitor a secondary cell or a sub-band for the RAR.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to transmit, to a base station, a capability report indicating a capability of the UE to support multi-transmission time interval scheduling. The UE may then receive, from the base station based on the capability report, a first configuration of a first processing mode for the UE that is associated with communications scheduled for a single transmission time interval, and a second configuration of a second processing mode for the UE that is associated with communications scheduled for a scheduling interval spanning a plurality of transmission time intervals. The UE may receive, from the base station, an indication to apply the first processing mode or the second processing mode, and may communicate with the base station based on the indication.

Abstract: A method, apparatus, and computer-readable storage medium for wireless communication at a first user equipment (UE) is provided. The UE receives an indication of one or more timers associated with a radio resource control (RRC) connection establishment procedure or an RRC connection re-establishment procedure with a network entity via a relay. The UE transmits a request associated with an RRC connection to a second UE to be relayed to the network entity and monitors for a response from the network entity based on the one or more timers associated with the RRC connection establishment procedure or the RRC connection re-establishment procedure via the second UE as the relay.
