Description

Techniques for synchronization signal block transmission in full duplex communications Cross reference This patent application claims the benefit of U.S. patent application Ser. No. 18/500,861, entitled "TECHNIQUES FOR SYNCHRONIZATION SIGNAL BLOCK TRANSMISSION IN FULL-DUPLEX COMMUNICATIONS (technique for synchronous signal block transmission in full duplex communications)" filed by ZHANG et al at 2023, 11, 2, which is assigned to the assignee of the present application and expressly incorporated herein by reference. Technical Field The following relates to wireless communications, including techniques for synchronization signal block transmission in full duplex communications. Background Wireless communication 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 able to support 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 techniques 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 communication system may include one or more base stations, each supporting wireless communication for communication devices, which may be referred to as User Equipment (UEs). In some systems, certain devices (e.g., base stations, transmit-receive points, radio heads, or other network entities) may operate in a full duplex mode in which the devices transmit and receive signals using the same set of radio resources (e.g., the same or overlapping set of time and frequency resources). Efficient techniques for reliable communications when devices operate in full duplex mode may help to improve network efficiency, improve network throughput, and result in an enhanced user experience. Disclosure of Invention The described technology relates to improved methods, systems, devices, and apparatus supporting techniques for Synchronization Signal Block (SSB) transmission in full duplex communications. For example, the described techniques provide one or more symbols in a set of symbols to be configured for full duplex communication at a network entity, wherein the network entity receives uplink communications and transmits downlink communications on each of the one or more symbols. Further, according to the SSB configuration, at least the first symbol configured for full duplex communication may also be configured for SSB. According to some aspects, a User Equipment (UE) configured to monitor a first symbol for SSB may use a priority rule to determine whether to transmit uplink communications on the first symbol or to receive SSB on the first symbol. In some aspects, the priority rule may specify that the dynamically scheduled uplink transmission has a priority over receiving SSB and that the grant uplink transmission is configured to have a priority below receiving SSB. Thus, in such an aspect, if the uplink transmission is dynamically scheduled, the UE transmits the uplink transmission on the first symbol and skips receiving the SSB. In the case where the uplink transmission is a configuration grant transmission, the UE may skip the configuration grant transmission and receive SSB if the UE is configured to receive SSB on the symbol, and may transmit the configuration grant transmission on the symbol if the UE is not configured to receive SSB on the symbol. Additionally or alternatively, the UE may transmit capability information indicating whether the UE supports full duplex operation configured in SSB symbols. A method for wireless communication by a User Equipment (UE) is described. The method may include receiving first configuration information for full duplex communication of a set of symbols, the full duplex communication providing uplink communication and downlink communication for each symbol in the set of symbols, receiving second configuration information for a synchronization signal block transmission, wherein the second configuration information indicates that at least a first subset of symbols in the set of symbols is configured in symbols overlapping one or more symbols configured for the synchronization signal block transmission, receiving scheduling information indicating that uplink transmission is scheduled for transmission in at least a first symbol in the first subset of symbols, and configuring the first symbol for uplink communication or downlink communication based on a priority rule associated with the full duplex communication, wherein
