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.

Coreset enhancement for reduced bandwidth UEs initial access

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

Wireless communication device, network node and methods for handling data transmissions

Embodiments herein relate to a method, performed by a User Equipment (UE), for handling discontinous reception (DRX) operation. The method comprises applying a delay for at least one action performed as a response to data and/or signaling received by the UE during a predefined first time period after the UEhas entered an active state. Embodiments herein further relate to a method, performed by a network node, for handling discontinous reception (DRX) operation. The method comprises sending a configuration message to a User Equipment (UE), which message comprises information regarding actions to be delayed by the UE

Method and apparatus for handling discontinuous reception in a communications network

A method for a transfer of a UE context within a secondary network from a source secondary network node to a target secondary network node. The UE is served by a master network node and the source secondary network node. The method includes the following steps performed by the UE: receiving a first message indicative of a secondary network node measurement configuration; based on the measurement configuration, performing measurements of potential candidates for a target secondary network node; and sending a second message comprising a measurement report indicative of the measurements of potential candidates for a target secondary node.

Secondary node change measurement signaling in next generation radio network

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 the user equipment receiving a radio resource control (RRC) release message from a network node. The user equipment determines that the RRC release message includes a suspend configuration field. The user equipment applies delta signalling corresponding to a suspend configuration indicated by the suspend configuration field and transitions to an inactive state.

Release cause for transition from connected state

A wireless communication device is configured for use in a wireless communication system. The device in this regard is configured to receive a command that commands the device to perform a link switch from a source link to a target link responsive to fulfillment of a condition. The command may indicate a target link configuration relative to a source link configuration. The device is also configured to store information from which the target link configuration indicated by the command is determinable irrespective of any change to the source link configuration occurring after receipt of the command. In some embodiments, the device is configured to, responsive to fulfillment of the condition, perform a link switch from the source link to the target link using the target link configuration as determined from the stored information.

Link switch in a wireless communication system

A wireless communications device, operating according to a DRX configuration and configured to receive two-step grants for uplink transmissions, determines whether the device has received a first trigger of a two-step grant. The device enters a state in which the device listens on a physical downlink control channel for messages from the network, in response to determining that the device has received the first trigger, without necessarily receiving the second trigger.

Active time handling with 2-step granting

A method for dynamic link selection that comprises providing at least two wireless links between one or more network nodes and a wireless device. The at least two wireless links associated with at least two different radio access technologies. The method additionally includes obtaining control data to be sent to a first network node of the one or more network nodes. The control data is associated with a first radio access technology. The method additionally includes selecting one or more wireless links from among the at least two wireless links. The one or more links selected based on a first selection parameter. The one or more selected wireless links are to be used for the transmission of the control data to the first network node. The one or more selected wireless links comprise at least a first wireless link associated with a second radio access technology. The method further includes transmitting the control data associated with the first radio access technology to the first network node via at least the first wireless link associated with the second radio access technology. The method also includes obtaining the control data at the first network node and determining whether the received control data is duplicated control data.

Dynamic link selection

The invention refers to a transfer of a User Equipment, UE, context within a secondary network from a secondary network node (A) to a new secondary network node (B), wherein the UE () is served by a master network node () and the secondary network node (A), the method comprising: the UE receiving a first message () indicative measurement configuration constructed by the secondary network node (A); the UE performing, based on the measurement configuration, measurements of potential candidates for anew secondary network node (B); and the UE sending a second message () comprising a measurement report indicative of the measurements of potential candidates for the new secondary node. The invention further relates to a secondary network node adapted to perform the method steps of initiating sending a first message () indicative of a secondary network node measurement configuration to the UE (); and receiving a second message () comprising a measurement report indicative of the measurements of potential candidates for a new secondary node from the UE ().

Methods, systems and network devices for operating a network node to provide dual connectivity in a handover of a user equipment, UE, in a new radio telecommunications system are provided. Methods include sending, from the network node and to a target secondary node, an addition request message to allocate resources for the UE in the handover. Operations include receiving an addition request acknowledgement message from the target secondary node. The addition request acknowledgement message includes a context indication regarding a full radio resource control, RRC, context or a delta RRC context. The delta RRC context includes data that is updated relative to data in a current UE context. Operations include determining, based on context indication, a type of RRC context to provide to the target secondary node.

Full RRC configuration in EN-DC

A UE operating in a network that supports dual connectivity operation is configured to minimize the transmission of unnecessary UE failure indications. The UE detects secondary cell group (SCG) failure for the UE, in response to detecting one of a plurality of SCG failure-triggering events. The UE sends a UE failure indication message, in response to the detecting SCG failure, and refrains from sending further UE failure indication messages in response to SCG failure-triggering events, until the sending of further UE failure indication messages is reenabled. In some cases, the UE sets a state of the UE to a UE prohibit state to prohibit sending further UE failure indication messages while in the UE prohibit state. In other cases, the UE starts a prohibit timer to prohibit sending further UE failure indication messages during the prohibit timer.
