Abstract
Methods, systems, and devices for wireless communications are described. A device may receive a sidelink grant for forwarding a combined uplink grant to a plurality of user equipments (UEs). The device may transmit, based on the combined uplink grant, individual uplink grants to the plurality of UEs in accordance with the sidelink grant. The device may configure, via a control signal, a meta-surface to redirect one or more uplink transmissions from the plurality of UEs to the network entity in accordance with the individual uplink grants.
Claims30
An apparatus for wireless communication at a device, comprising:
- a processor;
- memory coupled with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- receive, from a network entity via an access link, a sidelink grant for forwarding a combined uplink grant to a plurality of user equipments (UEs);
- transmit, based at least in part on the combined uplink grant, individual uplink grants to the plurality of UEs in accordance with the sidelink grant;
- and
- configure, via a control signal, a meta-surface to redirect one or more uplink transmissions from the plurality of UEs to the network entity in accordance with the individual uplink grants.
An apparatus for wireless communications at a network entity, comprising:
- a processor;
- memory coupled with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- receive, from a device via an access link, an indication of a plurality of user equipments (UEs) associated with a meta-surface controlled by the device;
- transmit, via the access link, a combined uplink grant for the plurality of UEs;
- transmit, to the device via the access link, a sidelink grant for relay by the device to the plurality of UEs;
- and
- monitor for one or more uplink transmissions from the plurality of UEs via the meta-surface in accordance with the combined uplink grant.
An apparatus for wireless communication at a user equipment (UE), comprising:
- a processor;
- memory coupled with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- transmit, to a device, a channel measurement report indicating a channel measurement of a channel between the UE and a meta-surface associated with the device;
- monitor for an uplink grant for transmissions that are to be redirected from the UE to a network entity by the meta-surface;
- and
- transmit an uplink transmission in accordance with the uplink grant.
A method for wireless communication at a device, comprising:
- receiving, from a network entity via an access link, a sidelink grant for forwarding a combined uplink grant to a plurality of user equipments (UEs);
- transmitting, based at least in part on the combined uplink grant, individual uplink grants to the plurality of UEs in accordance with the sidelink grant;
- and
- configuring, via a control signal, a meta-surface to redirect one or more uplink transmissions from the plurality of UEs to the network entity in accordance with the individual uplink grants.
