Problems solved by technology

[0047] 4. DCI blind decoding complexity
Furthermore, in case new DCI formats with different sizes are defined, this increases the search space in the UE (i.e. increases the DCI blind decoding complexity at the UE)

Embodiment Construction

[0249] figure 1 A network device 100 for receiving a scheduling request 111 and sending a first message 101 according to various embodiments of the present invention is schematically shown.

[0250] The BS 100 is configured to receive a scheduling request 111 from a UE 110 , in particular a scheduling request for a multi-hop transmission 112 .

[0251] The BS 100 is further configured to send a first message 101 to one or more UEs 110, 120, 130, 140 in response to the scheduling request 111, wherein the first message 101 indicates that for the one or more UEs 110, 120, 130 , 140 perform multi-hop transmission 112 of one or more sidelink resources and / or sidelink resource allocation information.

[0252] For example, BS 100 may provide multi-hop DCI type 1 (MH-DCI type 1), which may include a baseline DCI that initially transmitting UE 110 may use. In addition, BS 100 can also provide corresponding resource allocations for intermediate UEs (eg, UE2 120 and UE3 130 ) with res...

Abstract

The present disclosure provides a network device (BS). The network device is configured to receive a scheduling request from a User Equipment (UE), in particular for a multihop transmission; and send a first message to one or more UEs in response to the scheduling request, wherein the first message indicates one or more sidelink resources and / or sidelink resource allocation information for the one or more UEs to perform a multihop transmission. It is also provided a wireless communication device (UE) configured to in particular send, to a network device or to another wireless communication device, a scheduling request for a multihop transmission; and receive a first message from the network device or the another wireless communication device in response to the scheduling request, wherein the first message indicates one or more sidelink resources and / or sidelink resource allocation information for one or more UEs to perform the multihop transmission.

Description

technical field [0001] The present disclosure relates generally to the field of mobile communications. Specifically, the present invention relates to a network device (network device, BS), a wireless communication device (UE), a method for the network device, and a method for the wireless communication device to provide multi-hop transmission. To this end, the present disclosure proposes new control information for multi-hop communication (for example, configured with downlink control information (DCI) (ie, multi-hop DCI) and / or multi-hop radio resource control (RadioResource Control, RRC) configuration form) to reduce the signaling overhead of multi-hop communication. Background technique [0002] Generally speaking, according to the New Radio (NR) vehicle-to-everything (V2X) research project (Study Item, SI) with the reference number "RP-181429", in the 3GPP wireless access network ( In the RadioAccess Network (RAN) plenary meeting, sidelink frequencies for frequency ran...
