Abstract: Current HARQ procedures for grant-based uplink transmissions may not be suitable for implementations in which a UE can simultaneously transmit multiple transport blocks (TBs) to a base station. However, in some scenarios, such as in some grant-free uplink transmission schemes, a UE may simultaneously transmit multiple TBs. Systems and methods are disclosed herein for performing HARQ for situations in which a UE simultaneously transmits multiple TBs to a base station. By using the systems and methods described herein, HARQ may therefore be performed in such situations.

Abstract: New Radio (NR) RRC includes an RRC_INACTIVE state, which introduces ambiguities in the network's knowledge of UE behavior. A mechanism is introduced for handling parameters received when a UE enters RRC_INACTIVE upon the UE attempting to resume an RRC connection and, as a response, receiving a Release or Suspend message. The timer associated to the mobilityControlInfo (equivalent to T320) is stopped and associated parameters discarded upon receiving RRC Release or Suspend. Information received in a Release or Suspend message is discarded upon receiving RRC Release or RRC Suspend.

Abstract: An apparatus of wireless communication is configured to compute an timing advance (TA) estimate for a target cell. The TA estimate may be computed based on a measured TA for the serving cell and a time difference between a cell-specific reference signal (CRS) from the serving cell and a CRS from the target cell. The apparatus is also configured to determine whether an overshoot condition has occurred based on the timing advance estimate for the target cell. Furthermore, the apparatus is configured to refrain from triggering a handover to the target cell if an overshoot condition has occurred.

Abstract: A method to transmit information includes: obtaining, by a terminal in a disconnected state, information about a current coverage class of the terminal; and sending, by the terminal, a first message to an access network device, where the first message carries information about a coverage class of the terminal. The terminal in the disconnected state actively reports the information about the coverage class, so that a network device learns of the information about the coverage class of the terminal in a timely manner. In this way, during communication, a communication limitation or communication resource waste caused by inconsistency between information about a coverage class of the terminal that is stored on a network side and information about an actual coverage class can be avoided, and network resources can be fully used.

Abstract: The present disclosure relates to the prioritization of devices taking part in a multi-user random access wireless communication. Based on some known conditions, devices that comply with the conditions are given preferential treatment during the random access period. The preferential treatment may refer to the eligible devices being allowed to access more resource units during the random access, or it may also mean faster access to the medium during the random access. By taking advantage of the methods described in the present disclosure, it is possible to assign higher priority to selected frame types and/or device categories in a multi-user random access wireless communication system.
