Abstract: An access point may perform a method for X2 communication set up in a wireless communication network. The method may include discovering a neighbor node at an access point, optionally in response to detecting a new neighbor node, or an address parameter change at a neighbor node. The method may further include transmitting to an X2 gateway (X2-GW), a registration message comprising an address of the neighbor node for X2 communication. The registration message may include at least two addresses of the at least one neighbor node, the two addresses corresponding to addresses at a higher protocol layer and a lower protocol layer, for example a transport network layer (TNL) address and radio network layer (RNL) address of the at least one neighbor node. The access point may further receive an acknowledgement message from the X2-GW for the registration message.

Abstract: Methods, systems, and apparatuses are described for managing communications in a wireless communications system. An inter-access point communications link between a first access point and a second access point is established. At the first access point, one or more performance statistics from the second access point are received via the inter-access point communications link. Communication to or from a mobile device via the first access point and the second access point, is managed based at least in part on the received performance statistics.

Abstract: A method of wireless communication by a user equipment (UE) includes receiving, from a network entity, a request for one shot hybrid automatic repeat request (HARQ) feedback for multiple HARQ processes. The method also includes transmitting, to the network entity, the one shot HARQ feedback in response to receiving the request. The method further includes starting or restarting a discontinuous reception (DRX) HARQ round trip time (RTT) timer for one of the multiple HARQ processes based at least on satisfying a condition, after transmitting the one shot HARQ feedback.

Abstract: Wireless communications systems and methods related to use of cyclic prefix (CP) extensions for channel occupancy time (COT) sharing among sidelink user equipment devices (UEs) are provided. A first UE detects a first sidelink transmission in a COT, the COT for sharing with multiple sidelink UEs including the first sidelink UE. The first UE may determine a CP extension length for transmitting a second sidelink transmission after the first sidelink transmission, where a gap duration between the first sidelink transmission and the second sidelink transmission satisfies a listen-before-talk (LBT) gap time threshold. The first UE may apply a CP extension having the CP extension length to the second sidelink transmission and transmit, to a second sidelink UE, the second sidelink transmission with the CP extension.

Abstract: Methods, systems, and devices for updating timing advance values for deactivated cells are described. A user equipment (UE) may transmit, to a first cell that is deactivated, a random access message for a timing advance probing procedure. The UE may transmit the random access message to the first cell. In some examples, the UE may receive, from a second cell, an activation command that activates the first cell and an indication of a timing advance value for the first cell generated based on the random access message. In other examples, the UE may monitor for a random access response (RAR) message from the first cell, the RAR message including an activation command that activates the first cell and an indication of a timing advance value generated based on the random access message. The UE may communicate with the first cell based on the activation command and the timing advance value.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a user equipment (UE) may support dual connectivity. That is, the UE may establish communications with a master node and a secondary node of a wireless communications network. The master node may correspond to a master cell group (MCG) and the secondary node may correspond to a secondary cell group (SCG). In some examples, as described herein, the UE operating in dual connectivity may collect data for optimization of the wireless communications network or upon detecting a failure associated with the master cell group or the SCG and transmit the collected data to a network entity (e.g., one of the master node or the secondary node), where the collected data is based on the SCG being in a deactivated state. In some examples, upon receiving the collected data, the network entity may attempt to recover from the failure.

Abstract: The present disclosure provide various methods, computer-readable media, and apparatuses for managing communication paths, which may include at least one direct communication path between UEs, such as a sidelink communication path. Illustratively, an apparatus of the present disclosure may be a UE or component thereof that is configured to establish a direct wireless communication link and an indirect wireless communication link with another UE to carry data associated with one traffic stream. Further, the apparatus may be configured to communicate with the other UE over at least one of the direct communication link or the indirect communication link after the direct communication link and the indirect communication link are established with the other UE.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a network entity, an indication of multiple transmission occasions for a transmission of a sidelink communication in an unlicensed spectrum. The first UE may transmit, to a second UE, the sidelink communication in a selected transmission occasion of the multiple transmission occasions for the transmission of the sidelink communication in the unlicensed spectrum. Numerous other aspects are described.

Abstract: An on-demand scheduling request (SR) design is disclosed. Such an on-demand or triggered SR operation provides pre-configuration of user equipments (UEs) with triggered SR resources. Base stations may also configure UEs to monitor for a trigger signal within a bit field of control signaling from the base station. Upon detecting the trigger signal within such bit field, the UEs may use the triggered SR resources for transmitting triggered SR requests. Such use of the triggered SR resources may be in response to UEs detected cancelation of other periodic configured SR resources.
