A computer readable storage medium is presented, having computer readable program instructions thereon for causing a processor to carry out the steps of: sub-dividing a time slot into consecutive time intervals, the time slot belongs to multiple time slots allocated to a first node for transmitting to a second node using a wireless time-division duplex communication link between the first node and the second node, the second node transmitting during separate time slots allocated to said second node; and disrupting communication between said first node and said second node by transmitting, using a transmitter, respective interference signals during at least some of said time intervals, each of said interference signals being transmitted on one of said frequency bands, wherein for at least two of said time intervals said interference signals are transmitted on different frequency band.

Systems and methods in which one or more wireless communication stations implement duplex-mode remediation to facilitate the signal communication when an issue with respect to self-interference is identified are described. Duplex-mode remediation may be implemented for various communication scenarios, such as for random access phase communications, for communications having different priorities, etc. A wireless communication station may implement one or more changes with respect to the full duplex operation of the wireless communication station based upon determining that an issue with respect to self-interference may be, or is being, experienced, such as to provide for a wireless communication station operating in an in-band full duplex mode to increase interference cancellation and/or to fall back to a sub-band full duplex mode or a half duplex mode, to provide for a wireless communication station operating in a sub-band full duplex mode to increase interference cancellation and/or to fall back to a half duplex mode.

Techniques and apparatus for achieving multi-cell synchronization for dual connectivity and carrier aggregation are described. In one technique, a timing difference between a first base station (BS) and a second BS is determined, where the first BS is in an asynchronous timing configuration with respect to the second BS. A measurement configuration for measuring signal(s) from the second BS is determined, based on the timing difference. The measurement configuration is signaled to a user equipment (UE) served by the first BS. The UE performs a measurement procedure for the signal(s) in accordance with the measurement configuration. In another technique, the second BS receives a synchronization request, which includes a first time stamp, from the first BS via a network interface between the first BS and the second BS. The second BS sends a synchronization response, which includes a second time stamp, to the first BS.

Methods, systems, and devices for wireless communications are described. An example method for wireless communication at a first user equipment (UE) may include receiving at least a first sidelink transmission from a second UE, wherein at least a second sidelink transmission from a third UE is scheduled contemporaneously with at least the first sidelink transmission from the second UE. The method may also include transmitting an indication in a transmission occasion to at least one of the second UE or the third UE based at least in part on a prioritization of information for the transmission occasion, wherein the indication indicates that at least the first sidelink transmission from the second UE is scheduled contemporaneously with at least the second sidelink transmission from at least the third UE.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may select, from a plurality of slot formats for supporting time division duplexing, a slot format for use during time division duplexing; transmit an information element that includes a half-slot slot-type to identify the slot format for use during time division duplexing; and communicate with a user equipment (UE) in a time division duplexing mode in accordance with the slot format. Numerous other aspects are provided.

A configuration information indication method and apparatus, applicable to systems such as a vehicle to everything V2X communication system and a vehicle-to-vehicle V2V communication system, to resolve a problem that SL transmission causes interference to DL transmission due to relatively poor indication accuracy of UL transmission time in the conventional technology. The method includes: receiving an uplink-downlink time division duplex TDD configuration from a network device; determining, based on first periodicity information included in the uplink-downlink TDD configuration, a first subcarrier spacing SCS corresponding to the first periodicity information, where the first SCS is used to indicate a sidelink SL reference SCS; and sending indication information to a second terminal device based on the uplink-downlink TDD configuration and the first SCS, where the indication information is used to indicate uplink UL transmission time corresponding to the first periodicity information.
