    摘要： Techniques for facilitating dedicated transmissions over preconfigured uplink resources. Embodiments include techniques to configure subsequent PUR resource utilization (e.g., one-at-a-time basis or on a periodic basis), changes to EDT signaling to allow functioning with PUR, etc. An example method performed by a wireless device configured for use in a wireless communication network includes transmitting (90), in an uplink message, a request for a configuration of preconfigured uplink resources. The method further includes receiving (100), during a connected mode in which the wireless device has a connection with the wireless communication network, control signaling indicating a first preconfigured resource configuration that configures a first preconfigured resource. The method also includes transmitting or receiving (120) user data using the first preconfigured resource.

    摘要： 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.

    摘要： In some embodiments, a method performed by a wireless device comprises: obtaining a timing advance (TA) value for uplink transmissions; receiving a grant for a radio resource control (RRC) inactive mode uplink transmission; measuring a reference signal associated with each beam of a plurality of beams at a first time; selecting a first beam based on the measured reference signals; measuring a reference signal associated with each beam of a plurality of beams at a second time in preparation for the RRC inactive mode uplink transmission; selecting a second beam for which the measuring was performed at the second time; and when the first selected beam is the same as the second selected beam and the reference signal for the first selected beam is within a threshold value of the reference signal for the second selected beam, transmitting the RRC inactive mode uplink transmission using the obtained TA.

    摘要： Exemplary embodiments include methods for transmitting uplink (UL) data, by a user equipment (UE), using preconfigured uplink resources (PUR) in a radio access network (RAN). Such methods include receiving, from a network node in the RAN, a first PUR configuration, and transmitting, based on the first PUR configuration, a first UL data message to the network node Such methods also include receiving, from the network node, a first acknowledgement (PUR ACK) of the first UL data message. The first PUR ACK indicates whether the first UL data message was correctly or incorrectly received by the network node, and includes information related to subsequent UL transmissions using PUR (e.g., a second PUR configuration, a fallback indication, etc.). Some embodiments also include transmitting a second UL data message. Other embodiments include complementary methods performed by a network node, as well as UEs network nodes and UEs configured to perform such methods.
