  • Patent number: 12096489
    Abstract: A method performed by a wireless device. The method may be understood to be for handling a random access procedure in a wireless communications network via a network node. The wireless device operates in the wireless communications network. The wireless device refrains, after having sent a first message to the network node requesting random access and having received a first random access response message from the network node, from stopping a timer. The timer is for a time window for receiving the random access response message. The wireless device also continues monitoring both: a) a radio channel for further random access response messages from the network node addressed to a temporary identifier, and b) the radio channel, addressed to a temporary identifier specifically addressing the wireless device.

  • Publication number: 20240259088
    Abstract: According to some embodiments, a method performed by a wireless device operating in a non-terrestrial network (NTN) comprises obtaining a first timing advance (TA) value for uplink transmission in the NTN. The first TA value comprises a reference TA value. The method further comprises obtaining a trigger condition for reporting a TA used by the wireless device for uplink transmission in the NTN and autonomously obtaining an adjusted TA value for uplink transmission. The adjusted TA is obtained via autonomous adjustment to the reference TA value based on a propagation delay between the wireless device and a serving satellite of the NTN. The method further comprises, upon determining the trigger condition for reporting the TA is satisfied, reporting the adjusted TA to a network node.

  • Patent number: 11968134
    Abstract: A method, in a wireless device that supports carrier aggregation (CA), the method comprising: receiving a configuration message, from a wireless network node, indicating that the wireless device is to directly activate two or more secondary cells. The method further comprises determining that at least a first one of the two or more secondary cells is to be activated by a first time and that at least a second one of the two or more secondary cells is to be activated by a second time, following the first time. The method also comprises activating the first one of the secondary cells by the first time and subsequently activating the second one of the secondary cells by the second time.

  • Patent number: 11956180
    Abstract: Example methods and apparatuses provide for the advantageous use of “first” and “second” indicators for cell state control with respect to a wireless communication device. When sent singularly, the first indicator indicates activated/deactivated state transitions according to corresponding sequential state transition logic implemented in the device, and the second indicator indicates activated/dormant state transitions according to corresponding sequential state transition logic implemented in the device. When sent jointly for a given serving cell of the device, the first and second indicators operate as a combinational pair that indicates what the operational state of the cell shall be for the device, irrespective of the current cell state.

  • Patent number: 11849420
    Abstract: According to certain embodiments, a method for synchronous control of timing configurations includes operating a wireless device according to a first timing configuration associated with a first delay duration for transmitting feedback to a network node. A second timing configuration associated with a second delay duration for transmitting feedback to the network node is received from the network node. The second delay duration is different from the first delay duration. In response to a first downlink transmission from the network node, a first feedback is scheduled for transmission at a transmission time determined based on the second delay duration associated with the second timing configuration.

  • Publication number: 20230088550
    Abstract: A wireless device operating in a communication network can, responsive to receiving a downlink control indication (“DCI”) command to activate or reactivate a configured grant (“CG”) configuration that is associated with a first transmission block (“TB”) having a first transmission block size (“TBS”), handling a non-idle hybrid automatic repeat request (“HARQ”) process on the CG configuration based on whether the first TBS is different than a second TBS of a second TB associated with the non-idle HARQ process. The non-idle HARQ process can include a process of retransmitting the second TB using the CG for which an associated media access control (“MAC”) protocol data unit (“PDU”) has been submitted to lower layers for transmission to a network node, but for which successful reception acknowledgment has not been received from the network node.
