    摘要: A method performed by a wireless device. The method is for handling uplink transmission to a network node. The wireless device determines, in inactive state, whether a size of a buffer of data for uplink transmission obtained in inactive state is smaller than a threshold. The wireless device then sends, to the network node, at least a first transmission comprising a first subset of the data, and an explicit or implicit indication of a number of remaining transmissions that are needed to send the remaining data. The sending of the first transmission is based on a result of the determining and is in inactive state. The wireless device also sends the remaining transmissions in inactive or in connected state based on one or more further indications. The one or more further indications are received from the network node or configured.

    摘要: A method is performed by a network node. The method comprises determining to use an extended random access preamble identifier, RAPID, for a random access procedure with a wireless device. The method further comprises transmitting a medium access control, MAC, protocol data unit, PDU. The MAC PDU comprises a header and one or more random access responses, RARs. Each RAR is associated with a corresponding subheader within the header of the MAC PDU. The random access procedure is associated with a first RAR of the one or more RARs and the extended RAPID for the random access procedure is indicated by a combination of one or more bits in the first RAR and one or more bits in the subheader that corresponds to the first RAR.

    摘要: In a wireless communication network that implements the RRC Resume procedure, an eNB (11) sends to a radio network device (30), which was previously connected and has been given a Resume ID, a paging message or Random Access Response message including an RRC Resume directive. The RRC Resume directive comprises at least an indication whether or not the radio network device (30) should perform an RRC Resume procedure. If the RRC Resume directive indicates the radio network device (30) should not perform an RRC Resume procedure, the radio network device (30) performs an RRC Connection procedure. If the RRC Resume directive indicates the radio network device (30) should perform an RRC Resume procedure, it may include additional information to optimize or otherwise assist the RRC Resume procedure. In this manner, RRC Resume signaling is avoided when the eNB (11) knows that it will not be successful, such as if a prior RRC connection context is not available or readily retrievable, or is invalid.

    摘要: A communication system for enabling/disabling EDT comprises UEs and a network node. The network node is configured to collect measurements regarding cell information, determine whether EDT is allowed to be used by the UEs to transmit data prior to completing an access procedure, and send a message comprising an EDT indication instructing whether EDT is allowed to be used by the UEs. The UE is configured to initiate a transmission to the network node, receive the message comprising the EDT indication, and determine whether EDT is allowed to be used based on the EDT indication. The communication system may be able to enable or disable EDT for the UE based the status of cell, such that the communication system may avoid a resource waste caused by an early indication in Msg1 or a larger uplink grant in Msg2, and further improve the network performance.

    摘要: A method of operating a wireless device in a wireless communication network. The method includes detecting first synchronization signaling of a first cell on first time and frequency resources. The first synchronization signaling comprises at least a first synchronization signal and a second synchronization signal. The method further includes detecting indication signaling on second time and frequency resources. The second time and frequency resources are derived based on the first time and frequency resources. The method further includes accessing the first cell if the indication signaling is detected on the second time and frequency resources. Accessing the first cell includes decoding a first system information message on a broadcast channel of the first cell. The first system information message indicates time and frequency resources of a first resource set. The disclosure also pertains to related devices and methods.
