Abstract: The present disclosure is related to methods, user equipments (UEs), and network nodes for managing time alignment (TA). The method at a UE for managing TA related configuration comprises: receiving, from a net-work node, one or more TA related configurations; determining a TA related configuration from the received one or more TA related configurations at least partially based on at least one of a beam in which the UE is currently camped, a reference signal which is currently detected by the UE, and a configured grant (CG) configuration which is currently applied at the UE; and applying the determined TA related configuration.

Abstract: A first wireless communication device (401, 404), WCD, transmits a first indication to a second WCD (401, 404) or receives a first indication from the second WCD. The first indication indicates a first time period (501) during which the first WCD is expected to monitor for receipt of a transmission. The first WCD monitors for receipt of a transmission during the first time period. The first WCD is not expected to monitor for receipt of a transmission during a second time period (502) before the first time period begins. The first WCD performs the transmission or receipt of the first indication after a link has been established between the first WCD and the second WCD for relaying of information to and/or from a network via one or more sidelink transmissions between the first WCD and the second WCD.

Abstract: Systems and methods for determining timing advance (TA) validity are disclosed. In some embodiments, systems and methods are disclosed herein in which a wireless device implicitly considers a TA to be valid in a full cell when no TA validation mechanisms are explicitly configured. In other embodiments, systems and methods are disclosed herein in which a timer serves a dual purpose. If the timer is set to infinity, a wireless device will always consider a TA to be valid within a given cell, and at the same time will disable other TA validation mechanisms. Otherwise, the wireless device will interpret the timer as indicating for how long the TA value that the wireless device possesses is considered to be valid. Benefits of the solutions described herein include reducing signaling bits in the configuration and avoiding the possibility of conflicting configurations.

The first and/or second condition may for example include that the WCD experiences a loss of connection or loss of coverage, or that the WCD experiences a radio link failure.

Abstract: A method of controlling an indication of user data in a buffer of a User Equipment (UE) is provided. The user data is for Small Data Transmission (SDT) when the UE is in inactive mode. Based on a threshold value related to an amount of the user data for SDT, the UE determines whether to include an indication into a first uplink grant allocation transmission. The indication would indicate that user data is in the buffer. When an indication of user data in a buffer is not included in the first uplink grant, this indicates that the amount of data left in the buffer is less than the threshold value minus the first allocated grant transmission size, and when an indication of user data in a buffer is included, the indication indicates how many further transmissions are needed for transmitting the rest of the pending data.

Abstract: A method performed by a user equipment (UE) for handling communication in a wireless communications network is described. The UE obtains an indication of a first size of a grant for a first type of data transmission and transmits an access request to a radio network node to perform data transmission of the first type of data transmission. Then the UE receives a grant from the radio network node. The grant indicates a size for granted data transmission, or comprises a type indication of type of data transmission of the granted data transmission. The UE compares the first size with the indicated size in the grant, or the first type of data transmission and the type of data transmission indicated by the type indication in the received grant and based on the comparison, determines whether to use the received grant for performing data transmissions or not.
