US 12,750,117 B2 · Systems and methods for responding to a maximum permissible exposure condition

Abstract

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for responding to a maximum permissible exposure (MPE) condition in uplink communications. In one aspect, a user equipment (UE) wireless device may detect an MPE condition associated with a cell in an uplink channel from the UE in the wireless communication network. The UE may configure a medium access control layer control element (MAC-CE) to indicate information related to the cell associated with the detected MPE condition and an alternative beam that avoids an MPE condition for use in uplink communications. The configured MAC-CE may include a synchronization signal/physical broadcast channel resource block indicator (SSBRI) or a channel state information resource indicator (CRI) that indicates an alternative UE panel, a feasible UE panel, Tx beam for UL transmissions or Tx beam for UL transmissions taking into account the detected MPE condition.

Dependent claims

A method performed at a user equipment (UE), comprising:

configuring, by the UE, a medium access control control element (MAC-CE) that indicates information related to a cell, wherein the information indicates a maximum permissible exposure (MPE) condition and an alternative beam that avoids the MPE condition, wherein the alternative beam is a candidate beam for use in communications, wherein the MPE condition is between the UE and the cell, wherein the information indicates an identifier of the alternative beam for uplink beam switching that avoids the MPE condition, and wherein the identifier of the alternative beam that avoids the MPE condition includes information related to a reference signal identifier associated with the alternative beam;
and
transmitting the MAC-CE for transmission.

An apparatus for wireless communications, comprising:

a processing system that includes one or more processors and one or more memories coupled with the one or more processors, the processing system configured to cause a user equipment (UE) to:
configure a medium access control control element (MAC-CE) that indicates information related to a cell, wherein the information indicates a maximum permissible exposure (MPE) condition and an alternative beam that avoids the MPE condition, wherein the alternative beam is a candidate beam for use in communications, wherein the MPE condition is between the UE and the cell, wherein the information indicates an identifier of the alternative beam for uplink beam switching that avoids the MPE condition, and wherein the identifier of the alternative beam that avoids the MPE condition includes information related to a reference signal identifier associated with the alternative beam;
and
transmit the MAC-CE for transmission.

A user equipment (UE), comprising:

a processing system that includes one or more processors and one or more memories coupled with the one or more processors, the processing system configured cause the UE to:
configure a media access control control element (MAC-CE) that indicates information related to a cell, wherein the information indicates a maximum permissible exposure (MPE) condition and an alternative beam that avoids the MPE condition, wherein the alternative beam is a candidate beam for use in communications, wherein the MPE condition is between the UE and the cell, wherein the information indicates an identifier of the alternative beam for uplink beam switching that avoids the MPE condition, and wherein the identifier of the alternative beam that avoids the MPE condition includes information related to a reference signal identifier associated with the alternative beam;
and
a transmitter configured to transmit the MAC-CE.
