A method, system and apparatus are disclosed. A network node configured to communicate with a wireless device is provided. The network node includes processing circuitry configured to indicate, in downlink control information, DCI, a first modulation and coding scheme, MCS, associated with first transport block, TB, indicate, in the DCI, a second MCS associated with a second TB where the first MCS is indicated by a first MCS field size and the second MCS is indicated by a second MCS field size less than the first MCS field size, and communicate with the wireless device based on the first MCS and the second MCS.

Modulation and coding scheme (MCS) signalling for multi-carrier scheduling

Methods, wireless devices (WD), and network nodes are disclosed. For example, there is disclosed a network node configured to communicate with a wireless device in a cell. The network node is further configured to, and/or includes a radio interface and/or includes processing circuitry configured to communicate a timing advance offset to the wireless device for adjusting the uplink transmission relative to the downlink reception in the cell. The timing offset is based on the timing offset used by another wireless device in another cell to adjust the timing of uplink transmission relative to the downlink reception timing. Furthermore, the cells are configured to operate using TDD configurations.

Timing alignment for wireless device to wireless device measurements

There is disclosed a method of operating a network node () in a radio access network, the method comprising detecting Physical Random Access CHannel, PRACH, transmission from a user equipment (), wherein the PRACH transmission covers a plurality of time intervals, wherein detecting comprises associating different weights to different time intervals. The disclosure also pertains to related devices and methods.

PRACH detection in a radio access network

Embodiments include exemplary methods and/or procedures for receiving a physical uplink shared channel (PUSCH) in a cell of a time-division-duplexed (TDD) radio access network (RAN). Embodiments include determining whether remote base station interference is present in uplink transmissions in the cell and, based on the determining result, configuring activation or deactivation of code block group (CBG) based retransmissions in the cell, sending control messages to one or more UEs in the cell, for applying the configuration, and decoding subsequent PUSCH transmissions received from the one or more UEs based on the configuration. Embodiments also include network nodes configured to perform the exemplary methods and/or procedures.

Remote interference mitigation for physical uplink shared channel (PUSCH)

Embodiments include exemplary methods for CLI mitigation. The methods comprise receiving (), from at least one sending network node, a TDD configuration of the at least one sending network node, the TDD configuration identifying at least one slot of the TDD configuration as either a fixed uplink slot or a fixed downlink slot, and at least one slot of the TDD configuration as a flexible slot for which at least one symbol has an undefined transmission direction and the remaining symbols of the slot, if any, have a defined transmission direction. The methods also comprise adapting () operations in a cell based on the received TDD configuration for mitigating CLI with the at least one sending network node. Embodiments also include network nodes configured to perform the exemplary methods and/or procedures.
