摘要： A method performed by a wireless device (120) for transmitting a Random Access, RA,message to a radio network node (110). The wireless device and the radio network node operate in a wireless communications network (100). The wireless device determines a preamble from a group of preambles associated with an RA message size larger than the threshold value. This is done when the wireless device has a message to transmit that is larger than a threshold value. The wireless device transmits the determined preamble to the radio network node. Further, the wireless device receives, from the radio network node, an indication indicating that repetitions of transmission of an RA message are to be applied. Furthermore, the wireless device transmits, to the radio network node, the message in the RA message in accordance with the indication.

摘要： According to certain embodiments, a method in a wireless device for performing a random access procedure comprises preparing a first random access radio resource control (RRC) message that includes random access data and preparing a second random access RRC message that includes the same random access data split into a first part and a second part. The 5 method further comprises receiving a first uplink grant for transmission of a random access RRC message. The method further comprising determining whether the first random access RRC message can be transmitted in the amount of transmission resources granted by the first uplink grant. Upon determining the first random access RRC message cannot be transmitted in the transmission resources granted by the first uplink grant, the method comprises 0 transmitting the first part of the second random access RRC message to a network node.

摘要： Systems and methods for delivery of on-demand system information in a cellular communications network are disclosed. In some embodiments, a method of operation of a network node comprises transmitting, to a User Equipment (UE), minimum system information including a set of signal quality indication levels and corresponding random access parameter(s) and detecting a random access request from the UE that uses the random access parameter(s) configured for the signal quality indication level that corresponds to a signal quality level measured at the UE. The method further comprises deciding whether to deliver on-demand system information to the UE via a broadcast or dedicated signaling based on the signal quality level measured at the UE, broadcasting on-demand system information upon deciding to deliver on-demand system information via a broadcast, and delivering on-demand system information to the UE via dedicated signaling upon deciding to deliver on-demand system information via dedicated signaling.

摘要： Embodiments herein relate to a method implemented by a wireless communication device(10). The wireless communication device (10) transmits data to a radio node (12) of a wireless communication network(1). The wireless communication device (10) monitors for a positive acknowledgement or a negative acknowledgement of the data from the radio node(12). The wireless communication device (10) retransmits the data to the radio node(12) when said monitoring indicates reception of a negative acknowledgement of the data. The wireless communication device (10) refrains from retransmitting the data to the radio node(12) when said monitoring indicates reception of a positive acknowledgement of the data. The wireless communication device (10) also refrains from retransmitting the data to the radio node(12) when said monitoring indicates neither reception of a positive acknowledgement of the data nor reception of a negative acknowledgement of the data.

摘要： A radio base station, a relay node and a respective method therein are provided for communicating data to a user equipment, the relay node being associated with the base station, wherein a downlink transmission to the user equipment is scheduled on subframe(s) available for the base station. The method in the radio base station comprises detecting that at least a part of the available subframes are not needed for downlink transmission to the relay node; and un-reserving at least one of the not needed subframes. The method further comprises transmitting, to the relay node, a release notification message notifying the relay node of the unreserved subframes for enabling the relay node to use the unreserved subframes for downlink transmission.

摘要： Systems and methods are disclosed herein for Control Resource Set (CORESET) enhancements for initial access. In one embodiment, a method performed by a wireless communication device comprises receiving and decoding a Physical Downlink Control Channel (PDCCH) transmission in a CORESET in accordance with at least a portion of a Control Channel Element (CCE) to Resource Element Group (REG) mapping. The PDCCH transmission comprises one or more CCEs. The CCE to REG mapping comprises an interleaved portion that maps the one or more CCEs to a first set of REGs that are spread across a bandwidth of the CORESET, and a second portion that maps at least a portion of an additional CCE to at least a REG in a frequency gap between two REGs in the first set of REGs, the additional CCE corresponding to one of the CCEs mapped to the first set of REGs.

摘要： Systems, methods, and apparatus for handling communications relating to suspending a user equipment in a radio access network (RAN) are disclosed. An example method includes receiving, by a user equipment that is operating in a connected state, a radio resource control (RRC) release message. The user equipment determines, based on an indication in the RRC release message, whether to suspend the user equipment to an inactive state or an idle state, the indication comprising a presence or absence a suspend configuration field in the RRC release message. Responsive to determining that the indication is to suspend to an inactive state, the user equipment transitions to the inactive state.

摘要： According to one exemplary embodiment of inventive concepts, a UE that operates in a RAN may be configured to receive (1300) new radio, NR, radio resource control, RRC, messages from a secondary network node. The NR RRC messages may each contain a number that the secondary network node added to the NR RRC messages to indicate their respective order in a sequence which the NR RRC messages were sent by the secondary network node. The NR RRC messages may each contain parameters that the UE uses to configure its communications through a NR interface with the secondary network node. The UE may send (1302) NR RRC complete messages toward the secondary network node responsive to receipt of the NR RRC messages, wherein the NR RRC complete messages each contain an indication of the NR RRC message that was received. The UE may control (1304) the sending of the NR RRC complete messages to indicate to the secondary network node whether the NR RRC messages are received in an order that is the same as the sequence.

摘要： Embodiments herein disclose a method performed by a wireless device (10) for handling connections in a wireless communication network, wherein the wireless device (10) is configured with a split signaling radio bearer to a first radio network node (12), being a master radio network node, and a second radio network node (13), being a secondary radio network node. The wireless device detects a radio link problem to the first radio network node (12); and transmits a failure report to the first radio network node (12) over the split signaling radio bearer via the second radio network node (13). The failure report indicates the radio link problem to the first radio network node (12).
