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.

Abstract: A method performed by a User Equipment (UE) for handling a Synchronization Signal Block (SSB) from a network node in a wireless communications network is provided. The UE operates with a reduced bandwidth. The UE detects an SSB from the network node, and that a bandwidth of the SSB is larger than the bandwidth of the UE. The UE determines which part of the SSB to skip to make the bandwidth of the SSB equal or smaller than the bandwidth of the UE, such that the UE is capable of receiving the SSB. The part of the SSB to be skipped is determined based on a predicted decoding performance of the SSB.

According to some embodiments, the indication whether the wireless device is to provide a RedCap indication via the message 1 is provided by whether a physical random access channel, PRACH, partition between RedCap wireless devices and other wireless devices is configured.

Abstract: A wireless device performs an uplink transmission, such as an idle-mode uplink transmission using preconfigured uplink resources (PUR). The wireless device determines whether a serving-cell signal measurement M2 was completed within a predetermined range of time before a reference time T2, the reference time T2 corresponding to an uplink transmission opportunity. Responsive to determining that the serving-cell signal measurement M2 was not completed within the predetermined range of time, the wireless device either defers transmission to a subsequent transmission opportunity, or drops the uplink transmission, or collects an additional serving-cell measurement M2? that falls within the predetermined range of time, for use in validating a TA for transmitting at the transmission uplink opportunity and/or for estimating a PL for power control of a transmission at the uplink transmission opportunity.
