Abstract: Example embodiments of the present disclosure provide a solution for handling expiry of at least one time alignment timer (TAT) of multiple timing advance groups (TAGs) associated with a serving cell. In an example method, the terminal device receives determines at least two TAGs for a serving cell, wherein the at least two TAGs comprise a primary TAG and a secondary TAG. The terminal device determines whether at least one TAT of the at least two TAGs has expired and maintain, based on determining that the at least one TAT has expired, one of the primary TAG and the secondary TAG. In this way, only a single TAG is maintained once the terminal device has single TAT/no TAT running removing ambiguities in RA procedure/UL signal transmissions. Since the network is aware of the TAT expiry, it knows behaviour of the terminal device and can act accordingly.

Abstract: Example embodiments of the present disclosure relate to spatial pattern adaptation. An apparatus determines, based at least on a spatial pattern switching between at least two spatial patterns of a network device, one or more reference signal, RS, resources or RS occurrences from a plurality of RS resources or RS occurrences. The apparatus transmits, to the network device, at least one report comprising one or more measurements based at least on the one or more RS resources or RS occurrences. In this way, channel and interference measurement performance can be adapted to the dynamic switching of antennal or spatial pattern. Both the UE and the gNB have a common knowledge of which resources are used by the UE for deriving channel and interference measurement.

Abstract: Systems, methods, apparatuses, and computer program products for reporting of feasibility of activated transmission configuration indicator/transmission coordination indication (TCI) states. For example, a user equipment (UE) may determine whether one or more measurements satisfy one or more thresholds for one or more TCI states, and may transmit an indication of whether the one or more measurements satisfy the one or more thresholds. The UE may then deactivate at least one of the one or more activated TCI states, or may activate one or more additional TCI states, based on the indication, and may use one or more of the activated TCI states for a downlink (DL) or uplink (UL) transmission.

Abstract: The present disclosure relates generally to the field of wireless communications and, in particular, to techniques for issuing criteria-based retransmission grants for pending Media Access Control (MAC) Protocol Data Units (PDUs) generated and buffered in a user equipment (UE) in a wireless communication network. In particular, the UE is configured with at least one criterion for determining which of the pending MAC PDUs stored in the UE (e.g., in the HARQ buffers) could be transmitted by using radio resources of a retransmission grant issued by a network node. In other words, the UE should determine whether at least one of the pending MAC PDUs meets the at least one criterion. The at least one criterion may be signalled to the UE either in the retransmission grant or independently from the retransmission grant. If none of the pending MAC PDUs meets the at least one criterion, it is also allowed to apply the at least one criterion to a new MAC PDU, thereby making it possible to use the retransmission grant issued by the network node as a new transmission grant (provided that the new MAC PDU meets the at least one criterion). Thus, by using such a retransmission grant, it is possible to provide efficient MAC PDU recovery and resource usage.
