Abstract: A method performed by a wireless device for determining a timing advance (TA) offset in a new radio (NR) network is described herein along with associated network devices and systems. An exemplary method includes obtaining an indication of whether a carrier frequency of the NR network coexists with a carrier frequency of a long term evolution (LTE) network, determining, based on whether the carrier frequency of the NR network coexists with carrier frequency of the LTE network, a TA offset for uplink transmission; and transmitting an uplink transmission using the determined TA offset.

Abstract: A method of operating a wireless device may be provided. A wireless device may receive a release message from a network node of a radio access network. The release message may include an identification of a redirected carrier. In response to the release message omitting synchronization block related parameters for the redirected carrier, the wireless device may check in measurement information configured for the wireless device for the synchronization block related parameters for the redirected carrier; and may perform synchronization signal measurements for the redirected carrier using the synchronization block related parameters in the measurement information.

Abstract: In New Radio, NR, when a SR PUCCH resource to which a triggered SR is mapped overlaps with a PUCCH carrying UCI, such as HARQ-ACK and/or CSI, an indication of the corresponding schedulingRequestID, which determines the logical channel ID with new data, is directly encoded in the UCI. That is, rather than directly transmit the relevant SR PUCCH resource(s), which indirectly identifies the SR ID, an indication of the SR ID is directly transmitted on the PUCCH transmission. The encoding of an indication of SR ID may comprise adding bits to UCI to be transmitted, for PUCCH formats 2, 3, or 4. For PUCCH format 0, encoding the indication of SR ID comprises adding an initial cyclic offset indicating the triggered SR.

Abstract: According to an aspect, a UE in an uplink split-bearer configuration is configured to transmit PDUs by a first RLC entity via a first uplink transmission path and/or by a second RLC entity via a second uplink transmission path. The UE determines a total amount of data volume from PDCP data volume and RLC data volume pending for initial transmission in the two RLC entities. The UE decides whether submission of PDCP data volume is allowed to either of the two RLC entities or to only the first RLC entity, based on whether the total amount of data volume meets or exceeds a first threshold. The UE also reports the PDCP data volume to both the first and second uplink transmission paths or only the first uplink transmission path, based on whether the total amount of data volume meets or exceeds a first threshold.

Abstract: Among other things, the method and apparatus examples herein provide a solution to the problems that arise regarding the need for a wireless device to achieve source synchronization in a beam-based system, where the wireless communication network does not define “cells” for connected-mode wireless devices. The problems relate to how a wireless device can re-synchronize with its source access node in a beam-based system that mainly relies on self-contained transmissions from transmission points in the network. As one example advantage, the contemplated methods and apparatus enable wireless devices to perform measurements to support mobility procedures even when no data transmissions are scheduled.

Abstract: Power headroom reporting and report handling are discussed in the context of a Physical Uplink Shared Channel (PUSCH), on which a user equipment (UE) has no valid uplink grant, and a Physical Uplink Control Channel (PUCCH) on which a UE has no transmission.

Accordingly, exemplary embodiments provide for predetermined, known values to be used by the UE to calculate the power headroom, and by the eNodeB to understand the meaning of a received power headroom report.
