Abstract: Various embodiments of the present disclosure provide a method for multicast communication. The method which may be performed by a terminal device comprises receiving a first downlink channel including a first downlink assignment index from a network node. The first downlink channel is associated with a first traffic of the terminal device. The method further comprises determining that the first downlink assignment index is for the first traffic, according to the association between the first downlink channel and the first traffic. According to various embodiments of the present disclosure, hybrid automatic repeat request feedback may be implemented efficiently and flexibly for different traffics such as multicast and unicast traffics.

Abstract: A method and a apparatus for random access. The method for random access implemented at a base station may comprise sending a first message for triggering random access to a terminal device (210), wherein the first message indicates a first UL carrier of two candidate UL carriers for the random access and receiving a random access request from the terminal device (215). The two candidate UL carriers include a normal uplink carrier and a supplementary uplink carrier.

Abstract: Various embodiments of the present disclosure provide a method for multicast communication. The method which may be performed by a terminal device comprises receiving an uplink resource indicator for a multicast traffic of the terminal device from a network node. The uplink resource indicator may be used to indicate different uplink resources for multicast feedback of different terminal devices in a multicast group receiving the multicast traffic. The method further comprises determining an uplink resource for multicast feedback of the terminal device for the multicast traffic, according to the uplink resource indicator. In accordance with various embodiments of the present disclosure, hybrid automatic repeat request feedback may be implemented efficiently and flexibly for different traffics such as multicast and unicast traffics.

Abstract: Various embodiments of the present disclosure provide a method for multicast communication. The method which may be performed by a terminal device comprises receiving a multicast traffic and/or a unicast traffic from a network node. The method further comprises transmitting feedback for the multicast traffic and/or the unicast traffic to the network node, according to a feedback codebook. The feedback codebook is based at least in part on a first feedback codebook type for the multicast traffic and/or a second feedback codebook type for the unicast traffic. According to various embodiments of the present disclosure, hybrid automatic repeat request feedback may be implemented efficiently and flexibly for different traffics such as multicast and unicast traffics.

Abstract: The disclosure relates to methods and nodes for handling sensing of an object in an environment served by a wireless communication network employing joint communication and sensing. A method (1000) by a first radio node comprises transmitting (1002) a first signal having a first parameter setting for detecting a property of the object using sensing and, upon reception of information on a delayed and/or distorted version of the first signal either transmitting (1005) a second signal having a second parameter setting for determining properties of the object using sensing or reporting (1006) information on the property of the object to a further node that causes transmission of the second signal having the second parameter setting for determining the properties of the object in the environment using sensing. The second parameter setting provides for sensing at higher resolution, in a wider range and/or with higher reliability than the first parameter setting.
