The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or TRP. In one aspect, the apparatus can receive, on a first CC, first DCI from a first TRP and second DCI from a second TRP, the first DCI indicating one of a first set of TCI states and the second DCI indicating one of a second set of TCI states. The apparatus can also receive, on a second CC, a first PDSCH from the first TRP and a second PDSCH from the second TRP, a first time offset being between the first DCI and the first PDSCH and a second time offset being between the second DCI and the second PDSCH. The apparatus can also determine a QCL assumption based on at least one of the first time offset, the second time offset, and a QCL time duration.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication identifying one or more blocked beams that are unavailable to use for uplink or downlink communication. The UE may determine one or more beams to use for communication with the base station based at least in part on the indication identifying the one or more blocked beams. Numerous other aspects are provided.

A system and method for providing time domain allocations in a communication system. In an embodiment, an apparatus operable in a communication system and including processing circuitry is configured to receive an indication of a time domain allocation in downlink control information associated with a radio network temporary identifier (“RNTI”) identifying the apparatus, and employ the time domain allocation associated with the RNTI for transmissions associated with the apparatus. In another embodiment, an apparatus operable in a communication system and including processing circuitry is configured to associate a time domain allocation with a RNTI identifying a user equipment, and provide an indication of the time domain allocation in downlink control information to allow the user equipment to employ the time domain allocation associated with the RNTI for transmissions associated therewith.

Embodiments of the present disclosure provide a wireless communication method and device, and a network device. A wireless communication method includes: determining a target reception power value; performing control on at least one of a first transmission power or a second transmission power according to the target reception power value, thereby enabling a difference between a first reception power and a second reception power to be less than a preset power threshold. A wireless communication method includes: determining a reference time; performing control on at least one of a first transmission time or a second transmission time according to the reference time, thereby enabling a difference between a first reception time and a second reception time to be less than a preset time difference.

The present disclosure provides an analytical framework to investigate judicious topology reweighting of radio networks of clocks, when distributed time transfer and synchronization are based on physical layers and subject to the presence of false timing signals. Protagonist clocks exchange timing information pairwise, which is modeled as clocks tending to follow the majority of their neighbors. Antagonist clocks inject false timing signals, thereby, influencing the timing synchronization of (some of) the other protagonist clocks they meet. A class of pursuit-evasion graphical games subject to complete state observations and exploitation of phase noise disturbances, is proposed in designing clock steering protocols for resilient time metrologies that will be immune to erroneous timing signals injected into remote time dissemination networks.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine its position based on one or more position reference signals (PRSs), which the UE receives via different component carriers (CCs). The UE may maintain an active state with a first CC transmitting a PRS, while activating and deactivating a secondary CC that may transmit PRSs based on a periodic interval. Additionally, the UE may apply similar techniques for inactive BWPs where a PRS spans multiple BWPs. In some implementations, the position of the UE may enhance a UE mobility procedure based on determining a resource to use for the UE mobility procedure that is dependent upon the position of the UE. For example, the UE mobility procedure may include a random access procedure or a handover procedure. Additionally, the resources used for the mobility procedures may be quasi co-located with PRSs.

The present disclosure relates to a communication method and system for converging a 5.sup.th-Generation (5G) communication system for supporting higher data rates beyond a 4.sup.th-Generation (4G) system with a technology for Internet of Things (IoT).

According to the present invention, distribution characteristics of communication time delay are fully considered, accurate relative frequency offset estimation can be implemented, so the synchronization precision of average consensus-based clock synchronization is effectively improved, the maximum likelihood estimation solving is performed by adopting the iterative method, an estimation algorithm is simplified, and storage overhead is reduced.
