Techniques for adapting communication procedures based on device characteristics

#The following relates to wireless communications, including techniques for adapting communication procedures based on device characteristics.

#Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power). Examples of such multiple-access systems include fourth generation (4G) systems such as Long Term Evolution (LTE) systems, LTE-Advanced (LTE-A) systems, or LTE-A Pro systems, and fifth generation (5G) systems which may be referred to as New Radio (NR) systems. These systems may employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal FDMA (OFDMA), or discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-S-OFDM). A wireless multiple-access communications system may include one or more base stations or one or more network access nodes, each simultaneously supporting communication for multiple communication devices, which may be otherwise known as user equipment (UE).

#In some wireless communication system, UEs may modify communications with a base station for the purpose of coverage enhancement. In some cases, the UE may consider signal strength indicators to determine when coverage enhancement may be beneficial. Such techniques, however, may provide inaccurate estimates for the determination of whether coverage enhancement techniques may be beneficial as a measured signal strength at a UE (or other measured indicators) depend on a variety of factors.

#In some wireless communications systems, different channels or signals utilized during uplink procedures may require coverage enhancement (e.g., in frequency range 2 (FR2)). In one case, resources for coverage enhancement may be allocated to all user equipment (UEs) within a cell. However, allocating resources for coverage enhancement to all UEs may be inefficient and may result in coverage enhancement techniques being overutilized by UEs that have adequate coverage. In cases where coverage enhancement is specific to each UE of a cell (e.g., a UE may first determine if it may benefit from coverage enhancement and carry out uplink procedures based on the determination), the UE may not consider characteristics of the base station (e.g., antenna arrangement, transmit power, etc.) when determining whether it may benefit from coverage enhancement. As such, the wireless communications system may configure different criteria for activating coverage enhancement at the UEs based on the properties of the base station and indicating this criteria to the UEs may result in an increase in signaling (e.g., extra fields in system information or other signaling).

#In some examples, a UE may utilize a profile indicating a communication procedure and measurement configuration for performing a coverage enhancement technique, where the profile is based on communication parameters of a base station. The base station may select a profile from a set of profiles that may be predefined, preconfigured, or part of a communication standard. The base station may select the profile based on its current communication parameters (e.g., transmit power or antenna configuration) and transmit an indication of the profile to the UE. In some examples, the UE may identify or may be configured with a set of profiles including the selected profile. The UE may receive the indication of the profile and utilize the indicated profile to perform the communication procedure based on the measurement configuration indicated in the profile. In some examples, the communication procedure may be a random access channel (RACH) procedure and the profile may include one or more thresholds related to synchronization signal block (SSB) measurements which, if satisfied, may trigger a modified RACH procedure such as performing RACH repetitions over multiple RACH occasions. Such modifications to communication procedures may enhance coverage, an result in a higher likelihood of successful communications, among other benefits. The communication procedure may also include other communication procedures such as connection reestablishment or procedures performed after a RACH procedure such as a beam failure recovery (BFR) procedure, which may be modified based on the measurement configuration indicated in a profile for coverage enhancement. By taking into account base station communication parameters through the use of a profile, the UE may accurately determine when to modify a communication procedure and when coverage enhancement may be beneficial. According to aspects herein, UEs within a cell may efficiently utilize resources and reduce overhead signaling.
