There is disclosed method for a network apparatus, the method comprising configuring the network apparatus to use a first transmit and/or receive pattern selected from a plurality of available transmit and/or receive patterns for performing discovery procedures with another network apparatus, wherein the first transmit and/or receive pattern is selected from said plurality in dependence on at least the mobility of said network apparatus and/or on the relative mobility of said network apparatus to said another network apparatus.

Systems, methods, apparatuses, and computer program products for semi-static pattern for change of cell for physical uplink control channel (PUCCH) are provided. One method may include configuring at least one user equipment (UE) with a configuration for more than one serving cell for physical uplink control channel (PUCCH) transmission within at least one physical uplink control channel (PUCCH) cell group, and configuring the at least one user equipment (UE) with a configuration for a time-domain pattern of an applicable physical uplink control channel (PUCCH) cell within the at least one physical uplink control channel (PUCCH) cell group.

Semi-static pattern for change of cell for physical uplink control channel (PUCCH)

According to an aspect, there is disclosed a method that includes aligning, by a radio access network node wirelessly connected to at least two parent nodes and to a child node, an uplink reception timing associated with the child node with a downlink reception timing associated with a parent node of the at least two parent nodes.

Timing control in a radio access network node

A method for adjusting transmit timing is disclosed. The method includes determining a reference timing advance value TA, receiving a time offset parameter; and adjusting downlink transmit timing based on i) detected downlink receive timing of radio node and ii) the reference timing advance value TAand the time offset parameter.

Integrated access backhaul node downlink timing adjustment in presence of frequency offset

A distributed unit, DU, of a radio access node configured to operate in a scenario where the DU is one of multiple DUs serving links to a multi-connected entity, acquires a first DU radio resource configuration for the DU, acquires a first link radio resource configuration corresponding to a first link of a multi-connectivity link of a multi-connected entity, wherein the first link is served by the DU, acquires a multiplexing configuration of the multi-connectivity link, and determines availability of at least one radio resource for the multi-connectivity link based on the first DU radio resource configuration, the first link radio resource configuration, and the multiplexing configuration.

Dual connectivity conflict resolution for distributed units

A set of specific sequences including a set of root sequences and cyclic shifts thereof is searched, wherein it is started from a root sequence index indicating a root sequence of ordered root sequences, available cyclic shifts of the root sequence are included, and it is continued with a next root sequence if necessary for filling the set, interpreting the ordered root sequences in a cyclic manner.

Allocation of preamble sequences

A technique of performing a handover procedure involves providing a proper timing adjustment indication for the UE performing RACH-less HO. Even though the discussion herein is on IAB scenarios and the idea takes an advantage of IAB nodes being in fixed locations (i.e., not moving in the network), it can be applied to UEs in general. The timing adjustment provided in performing a HO in an IAB network according to the improved techniques involves computing a timing advance (TA) to be used by an IAB node prior to executing HO to an alternative serving node. Such a use of a TA may enable a bypassing of a RACH procedure when accessing a cell.

Timing advance for rach-less backhaul handover

According to the disclosure there is provided an apparatus comprising means for performing: receiving a configuration for a distributed unit of the apparatus for transmitting reference signals using a time domain resource of the apparatus, in accordance with a time domain transmission pattern; and receiving a configuration for a mobile termination unit of the apparatus for reception of reference signals using the time domain resource of the apparatus, in accordance with a time domain reception pattern; and selectively measuring received reference signals in dependence on a determination of whether measurement of received reference signals is required.

Implementations of advanced frequency synchronization in a mobile integrated access backhaul deployment are disclosed. An apparatus includes at least one processor, and at least one non-transitory memory including computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to perform: estimate a change in a propagation delay at two time instants, measure a time period of the two time instants using a local clock of a network node, wherein the two time instants correspond to a known timing of a received signal, subtract the change of the propagation delay from the measured time period, calculate a difference between the subtracted time period and a known timing of the received signal; and convert the difference to a frequency offset value to synchronize downlink transmission frequency between the network node and a parent node.

Various communication systems may benefit from inter-operator device-to-device operation. For example, communication systems of the third generation partnership project (3GPP) long term evolution (LTE) advanced (LTE-A) release12/13 (Rel-12/13) or future releases may use such operation with respect to D2D communications. A method can include preparing, at a network element operated by an operator, radio resource information related to one or more operators other than the operator. The method can also include broadcasting, by the network element, the radio resource information. The radio resource information can be configured to permit a user equipment served by the network element to perform device-to-device discovery and/or communication with another user equipment served by at least one of the one or more operators.
