Abstract: A method for adjusting transmit timing is disclosed. The method includes determining a reference timing advance value TAref, 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 TAref and the time offset parameter.

Abstract: An apparatus comprising at least one processor and at least one memory including computer code for one or more programs, the at least one memory and the computer code configured, with the at least one processor, to cause the apparatus at least to support for a determined period at least one hop within a multi-hop self-backhaul communications, wherein the determined period comprises: a first part within which information for controlling dynamic allocation between backhaul and access links within resource slots is passed between the apparatus and at least one further apparatus in the multi-hop self-backhaul communications; and a second part within which a dynamic slot pattern is implemented based on the information for controlling dynamic allocation between backhaul and access links within resource slots is passed between the apparatus and at least one further apparatus in the multi-hop self-backhaul communications.

Abstract: 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.

Abstract: A technique may include transmitting, by a user device in a proximity-based services wireless network via a first time-frequency resource identified by a first logical time index within N logical time resources and a first logical frequency index in the range from 0 to M−1, a first occurrence of a signal for the user device during a transmission period; determining a time index adjustment associated with the first logical frequency index; determining, by the user device, a second logical time index of a second time-frequency resource for transmitting from the user device a second occurrence of the signal within the transmission period, the second logical time index being determined based on the first logical time index and the time index adjustment associated with the first logical frequency index; and transmitting, by the user device via the second time-frequency resource, a second occurrence of the signal during the transmission period.
