US 2026/0280611 A1 · COMMUNICATIONS VIA TRANSMISSIVE SURFACES USING DIFFERENT BEAMS FOR UPLINK AND DOWNLINK

Abstract

Methods, systems, and devices for wireless communications are described. Structures such as buildings or vehicles may include transmissive surfaces (TSs) on glass surfaces that allow penetration of radio frequency signals through the glass surface. A user equipment (UE) within such a structure may communicate with a network entity outside of the structure via beams that are refracted through such TSs. In some examples, different TSs, and thus different sets of beams, may be used for uplink and downlink communications involving a UE and a network entity. Accordingly, a UE may receive downlink messages via a first set of beams and a first TS and may transmit uplink messages via a second set of beams and a second TS. In some examples, such decoupling of uplink and downlink beams in association with the use of different TSs may be based on satisfaction of a triggering condition.

Dependent claims

A user equipment (UE), comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the UE to:
communicate, with a network entity, control signaling associated with downlink beamforming via a first transmissive surface between the UE and the network entity, wherein the control signaling is further associated with uplink beamforming via a second transmissive surface between the UE and the network entity;
receive, via a first set of beams associated with the first transmissive surface, one or more downlink messages based at least in part on the control signaling;
and
transmit, via a second set of beams associated with the second transmissive surface, one or more uplink messages based at least in part on the control signaling, wherein the first set of beams are different from the second set of beams, and wherein the first transmissive surface is different from the second transmissive surface.

A method for wireless communications at a user equipment (UE), comprising:

communicating, with a network entity, control signaling associated with downlink beamforming via a first transmissive surface between the UE and the network entity, wherein the control signaling is further associated with uplink beamforming via a second transmissive surface between the UE and the network entity;
receiving, via a first set of beams associated with the first transmissive surface, one or more downlink messages based at least in part on the control signaling;
and
transmitting, via a second set of beams associated with the second transmissive surface, one or more uplink messages based at least in part on the control signaling, wherein the first set of beams are different from the second set of beams, and wherein the first transmissive surface is different from the second transmissive surface.
