The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing (OFDM) transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology. Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed.

Network architecture, methods, and devices for a wireless communications network

Systems and methods are disclosed herein for exchanging Sidelink (SL) User Equipment (UE) context and configurations between a Master Node (MN) and a Secondary node (SN), e.g., in normal Multi-Radio Dual Connectivity (MR-DC) operations. In some embodiments, the SL UE context and configuration are exchanged between the MN and the SN via inter-node Radio Resource Control (RRC) messages. In this way, the two network nodes (the MN and the SN) are aware of the SL transmission going on under their coverage and can take the necessary actions to guarantee a stable and reliable SL connectivity.

Sidelink transmission continuity

A method includes: obtaining a first sequence, where the first sequence includes T first subsequences; determining T encoding vectors based on the T first subsequences; generating T second subsequences based on one or more codebooks and the T encoding vectors, where each first subsequence corresponds to one column vector group in the one or more codebooks, and a column vector group corresponding to at least one of the T first subsequences includes at least two column vectors; and sending the T second subsequences.

Data transmission method and apparatus

Embodiments herein relate to a method performed by a UE () for handling communication in a wireless communication network. The UE () handles one or more data units based on a communication range requirement of one or more services, wherein the one or more data units are associated with the one or more services, by using a mapping of an indication of a communication range requirement and a radio resource for communication.

Method performed by a user equipment for handling communication in a wireless communication network

A method of establishing connections between wireless devices in a multi-hop sidelink communication network. The method comprises, at a wireless device: receiving a communication request message from a source wireless device; relaying the communication request message over a sidelink; receiving, from a target wireless device that received the relayed communication request message, a communication acceptance response message over a sidelink to establish a communication link between the wireless device and target wireless device; and relaying the communication acceptance response message received from the target wireless device to the source wireless device to establish a multi-hop communication link between the source wireless device and the target wireless device.

The present application generally relates to wireless communication technology. More particularly, it relates to a method and apparatus for controlling sidelink (SL) Quality of Service (QoS). According to one or more embodiments, a method for controlling sidelink (SL) Quality of Service (QoS) comprising the following steps carried out at a User Equipment (UE): a) generating QoS requirement from characteristics for one or more packets to be transmitted via a sidelink; b) determining bearer configuration corresponding to the QoS requirement; and c) performing SL transmission on the basis of the bearer configuration.

Method and apparatus for controlling sidelink QoS

Example wireless communication methods and apparatus are described. In one example method, a relay device receives a first signal sent by a first device, where the first signal carries a plurality of bits. The relay device decodes the first signal to determine first information corresponding to each of a plurality of first bits. The first information corresponding to each first bit is determined based on a probability that the first bit is 1 and a probability that the first bit is 0. The relay device sends the first information in a second signal to a second device, so that the second device can use the first information to decode the first signal.
