摘要： Embodiments include methods, performed by a user equipment (UE), for hybrid ARQ (HARQ) feedback in relation to multicast transmissions from a network node in a radio access network (RAN). Such methods include receiving, from the network node, first downlink control information (DCI) scheduling a first multicast transmission associated with the UE and determining a HARQ feedback mode for the first multicast transmission. Such methods also include, based on the first DCI, attempting to decode the first multicast transmission; and selectively transmitting HARQ feedback related to the first multicast transmission to the network node based on the determined HARQ feedback mode and on whether the attempt to decode is successful or unsuccessful. Embodiments also include complementary methods for a network node, as well as UEs and network nodes configured to perform such methods.

The methods further include evaluating the measurement or the demodulated and decoded information for each of the plurality of resources against a predetermined criterion, and then discontinuing the performing and evaluating of measurements, or discontinuing the demodulating and decoding and evaluation of information, in response to determining that the predetermined criterion is met, such that one or more resources in the predetermined set of resources are neither measured nor demodulated and decoded. The methods further comprise deactivating receiver circuitry, further in response to determining that the predetermined criterion is met. The method further comprises receiving, in a first downlink subframe, a first Orthogonal Frequency-Division Multiplexing transmission formatted according to a first numerology and receiving, in a second downlink subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology.

摘要： A relay node (150) for a wireless network is configured for transmissions on the basis of a radio frame with a plurality of subframes. The relay node (150) comprises a first relay path (630) and a second relay path (640). The first relay path (630) is configured to receive, in a first subframe of the subframes, first unicast transmission signals, to decode the first unicast transmission signals to obtain unicast data, and to forward the decoded unicast data by sending second unicast transmission signals in a second subframe of the subframes. The second relay path (640) is configured to receive, in a third subframe of the subframes, multicast transmission signals, to amplify the received multicast transmission signals, and to send the amplified multicast transmission signals in the third subframe. The relay node (150) may switch between the first relay path (630) and the second relay path (640) in order to implement a hybrid Decode-and-Forward and Amplify-and-Forward relaying operation.
