Description

IMPEDANCE MATCHING USING A TRAFFIC PATTERN IN A WIRELESS COMMUNICATION SYSTEM CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of U.S. Patent Application No. 18/930,795, entitled, “IMPEDANCE MATCHING USING A TRAFFIC PATTERN IN A WIRELESS COMMUNICATION SYSTEM,” filed on October 29, 2024, which is expressly incorporated by reference herein in its entirety. TECHNICAL FIELD [0002] Aspects of the present disclosure relate generally to wireless communication systems, and more particularly, to impedance matching in a wireless communication system. DESCRIPTION OF THE RELATED TECHNOLOGY [0003] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and the like. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing the available network resources. Such networks may be multiple access networks that support communications for multiple users by sharing the available network resources. [0004] A wireless communication network may include several components. These components may include wireless communication devices, such as base stations (or node Bs) that may support communication for a number of user equipments (UEs). A UE may communicate with a base station via downlink and uplink. The downlink (or forward link) refers to the communication link from the base station to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the base station. [0005] A base station may transmit data and control information on a downlink to a UE or may receive data and control information on an uplink from the UE. On the downlink, a transmission from the base station may encounter interference due to transmissions from neighbor base stations or from other wireless radio frequency (RF) transmitters. On the uplink, a transmission from the UE may encounter interference from uplink transmissions of other UEs communicating with the neighbor base stations or from other wireless RF transmitters. This interference may degrade performance on both the downlink and uplink. QLXX.P2144WO [0006] Wireless communication devices increasingly use antennas to communicate wireless signals. Techniques such as multiple-input, multiple-output (MIMO) and carrier aggregation (CA) may increase the amount of data communicated between wireless communication devices and may also involve a relatively large number of antennas. The antennas may be “tuned” using an antenna tuner (e.g., to adjust for an impedance mismatch and other conditions). A particular setting of an antenna tuner may be referred to as, or may correspond to, an antenna tuner codeword. [0007] Some wireless communication devices increasing use large display screens and large batteries. Such display screens and batteries may reduce or limit the amount of physical space for such antennas and antenna tuners. As a result, performance of some such wireless communication devices may be reduced or limited. SUMMARY [0008] The systems, methods and devices of this disclosure each have several innovative aspects, no single one of which is solely responsible for the desirable attributes disclosed herein. [0009] In some aspects, an apparatus for wireless communication includes a processing system including one or more processors and one or more memories coupled to the one or more processors. The processing system is configured to dynamically adjust antenna impedance matching circuitry in accordance with a codeword and as a function of a traffic pattern. The processing system is further configured to perform a wireless communication operation associated with the traffic pattern and in accordance with the codeword. [0010] In some additional aspects, a method of wireless communication performed by a device includes dynamically adjusting antenna impedance matching circuitry in accordance with a codeword and as a function of a traffic pattern. The method further includes performing a wireless communication operation associated with the traffic pattern and in accordance with the codeword. [0011] In some further aspects, a non-transitory computer-readable medium stores instructions executable by one or more processors to initiate, perform, or control operations. The operations include dynamically adjusting antenna impedance matching circuitry in accordance with a codeword and as a function of a traffic pattern. The operations further include performing a wireless communication operation associated with the traffic pattern and in accordance with the codeword. QLXX.P2144WO [0012] While aspects and implementations are described in this application by illustration to some examples, those skilled in the art will understand that additional implementations and use cases may come about in many different arrangements and scenarios. Innovations described herein may be implemented across many differing platform types, de
