Abstract: Acknowledgement feedback is conveyed to a network node (100) for unicast and multicast transmissions received by a wireless device (200). The wireless device (200) configures (310) uplink control channel resources responsive to an uplink channel format indicated by an uplink channel format indicator. Each possible ACK or NAK combination for the unicast and multicast transmissions maps to a different cyclic shift of a base sequence defined according to the uplink control channel format. The wireless device (200) receives (320) a unicast transmission and a multicast transmission. Further, when in a joint acknowledgement mode, the wireless device (200) configures (330) acknowledgement feedback for the received unicast and multicast transmissions according to the cyclic shift mapping and jointly transmits (340) the acknowledgement feedback for both the received unicast transmission and the received multicast transmission to the network node (100) in an acknowledgement time slot

Abstract: Embodiments herein include a method performed by a radio network node (12) configured for use in a wireless communication network (10). The method comprises receiving a message (16) of a procedure for random access by a wireless device (14) to a cell served by the radio network node (12). The method also comprises selecting, as a function of on which uplink bandwidth part (30-0…30-N) of the cell the message (16) was received and/or as a function of an information field (16A) of the message (16), a format of a random access response (18) to be transmitted as a response to the message (16). The method also comprises transmitting the random access response (18) with the selected format (16).

Abstract: A wireless device (14) receives a downlink control information message (20) on a physical downlink control channel. In some embodiments, the downlink control information message (20) schedules two or more non-redundant downlink transmissions to be transmitted to the wireless device (14) in respective transmission time intervals, TTIs, on a first downlink serving cell (16A) and one or more non-redundant downlink transmissions to be transmitted to the wireless device (14) in one or more respective TTIs on a second downlink serving cell. In other embodiments, the downlink control information message (20) schedules one or more non-redundant uplink transmissions to be transmitted from the wireless device (14) in one or more respective TTIs on a first uplink serving cell (18A) and one or more non-redundant uplink transmissions to be transmitted from the wireless device (14) in one or more respective TTIs on a second uplink serving cell (18B).

Abstract: The method is performed in network node for reducing the impact of interference in a cell from at least another neighbouring cell. The cell operates using a time division duplex, TDD, configuration, and the neighbouring cell operating using another TDD configuration. The TDD configurations are divided into different time units for at least downlink, DL, and uplink, UL, transmissions. The method includes identifying time units in the TDD configuration. The identification of a time unit is based on whether the time unit has a different configuration compared to the time unit in the another TDD configuration used in the neighbouring cell. The method further includes defining a restricted TDD configuration for use in the cell, where the restricted TDD configuration excludes transmission in the identified time units. Furthermore, the method further includes identifying a physical direction in which to apply the restricted TDD configuration. A network node, a computer program, and a computer program product for reducing the impact of interference from at least another wireless device operating in a neighbouring cell using another TDD configuration are also provided.
