Abstract

Methods, systems, and devices for wireless communications are described. Information related to an accessory installable on the UE may be transmitted to a network entity. The installation of the accessory on the UE may be associated with an effect on a signal coverage pattern of the UE. Based on transmitting the information, communications between the UE and network entity may be performed in accordance with a set of parameters that are based on the effect of the accessory on the signal coverage pattern of the UE.

First claim

What is claimed is:

1 . 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:
transmit, to a network entity, information related to an accessory that is installable on the UE and configured to at least partially cover the UE, wherein installation of the accessory on the UE is associated with an effect on a signal coverage pattern of the UE; and
communicate, with the network entity, in accordance with a set of parameters that are based at least in part on the effect of the accessory on the signal coverage pattern of the UE.

2 . The UE of claim 1 , wherein, to transmit the information related to the accessory, the one or more processors are individually or collectively operable to execute the code to cause the UE to:
transmit an indication of one or more beam property changes associated with the accessory being installed on the UE.

3 . The UE of claim 1 , wherein, to transmit the information related to the accessory, the one or more processors are individually or collectively operable to execute the code to cause the UE to:
transmit an indication of whether the accessory is installed on the UE.

4 . The UE of claim 1 , wherein, to transmit the information related to the accessory, the one or more processors are individually or collectively operable to execute the code to cause the UE to:
transmit an indication of one or more properties of the accessory.

5 . The UE of claim 4 , wherein the one or more properties of the accessory includes one or more materials included in the accessory, a dielectric constant associated with the accessory, a loss tangent associated with the accessory, a thickness of the accessory, or any combination thereof.

6 . The UE of claim 4 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
query a database for the one or more properties of the accessory; and obtain, from the database, the one or more properties of the accessory based at least in part on querying the database.

7 . The UE of claim 1 , wherein, to transmit the information related to the accessory, the one or more processors are individually or collectively operable to execute the code to cause the UE to:
transmit an indication of one or more signal coverage metrics for the UE associated with the installation of the accessory on the UE, wherein the one or more signal coverage metrics are based at least in part on the signal coverage pattern of the UE associated with the installation of the accessory on the UE.

8 . The UE of claim 7 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
receive, from the network entity, a message indicating whether a signal coverage metric of the one or more signal coverage metrics satisfies a corresponding signal coverage metric threshold.

9 . The UE of claim 7 , wherein the one or more signal coverage metrics comprises an indication of an in-coverage signal coverage, an indication of an out-of-coverage signal coverage, or both.

10 . The UE of claim 7 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
receive, from the network entity, a message indicating a modulation and coding scheme that is based at least in part on the one or more signal coverage metrics indicated via the information related to the accessory, wherein the set of parameters for communicating with the network entity comprises the modulation and coding scheme.

11 . The UE of claim 1 , wherein, to transmit the information related to the accessory, the one or more processors are individually or collectively operable to execute the code to cause the UE to:
transmit a first indication of one or more signal coverage metrics for a first frequency range and associated with the installation of the accessory on the UE and a second indication of the one or more signal coverage metrics for a second frequency range and associated with the installation of the accessory on the UE.

12 . The UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
configure a set of beam weights at the UE based at least in part on one or more beam property changes associated with the accessory being installed on the UE, wherein the set of parameters for communicating with the network entity includes the set of beam weights.

13 . The UE of claim 12 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
load, from memory of the UE and base at least in part on the one or more beam property changes associated with the accessory being installed on the UE, a codebook associated with the accessory being installed on the UE; and select, from the codebook, the configured set of beam weights.

14 . The UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
receive, from the network entity, an indication of one or more reference signal resources based at least in part on the accessory being installed on the UE, the one or more reference signal resources associated with adapting one or more beam weights at the UE, wherein the set of parameters for communicating with the network entity includes the one or more beam weights; and adapt the one or more beam weights based at least in part on the one or more reference signal resources, wherein the set of parameters comprises the one or more adapted beam weights.

15 . The UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
perform a first signal quality measurement on a communication link between the UE and the network entity before the accessory is installed on the UE; perform a second signal quality measurement of the communication link while the accessory is installed on the UE; and transmit, to the network entity, a message indicating a difference between the first signal quality measurement and the second signal quality measurement.

16 . The UE of claim 1 , wherein the one or more processors are individually or collectively further operable to execute the code to cause the UE to:
receive, from the network entity, a message comprising an indication of a signal quality of a communication link between the UE and the network entity when the accessory is installed on the UE.

17 . The UE of claim 16 , wherein, to receive the message indicating the signal quality of the communication link, the one or more processors are individually or collectively operable to execute the code to cause the UE to:
receive, from the network entity, an indication of whether to keep the accessory installed on the UE, an indication of a change to a modulation and coding scheme that is based at least in part on the accessory being installed on the UE, an indication to switch beams that is based at least in part on the accessory being installed on the UE, or any combination thereof; and transmit, to the network entity, a second message indicating of whether the accessory remains installed on the UE, whether the modulation and coding scheme is changed, whether the beams are switched, or any combination thereof.
