  • Patent number: 11870627
    Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless device maps data, a unique word (UW) sequence, and a suppression signal to a set of reserved time-domain resources based on a time-domain resource mapping and reservation rule to produce DFT input data. DFT processing is performed on the DFT input data to produce IFFT input data. IFFT processing is performed on the IFFT input data to produce the GI-based waveform with a data part (e.g., non-zero part) and a tail part (e.g., zero tail part). The wireless device may further transmit the GI-based waveform.

  • Patent number: 11844033
    Abstract: Certain aspects of the present disclosure provide techniques for detecting a potential collision between a scheduled uplink transmission and a synchronization signal block (SSB) and transmitting the scheduled uplink transmission. For example, in cases of inter-cell multi-transmission and reception points (multi-TRP), a user equipment (UE) may not be capable of simultaneously transmitting and receiving on the multiple serving cells. A first serving cell may indicate to the UE of SSB indices that are actually transmitted for a second serving cell. If there is a slot collision between one of the SSB to be transmitted and a scheduled uplink transmission, the UE may not be able to handle such collision. The present disclosure provides techniques for detecting a potential collision between a scheduled uplink transmission and one of the SSBs and transmitting the scheduled uplink transmission when one or more conditions are met.

  • Patent number: 11805026
    Abstract: Systems, apparatuses, and methods for utilizing training sequences on a replica lane are described. A transmitter is coupled to a receiver via a communication channel with a plurality of lanes. One of the lanes is a replica lane used for tracking the drift in the optimal sampling point due to temperature variations, power supply variations, or other factors. While data is sent on the data lanes, test patterns are sent on the replica lane to determine if the optimal sampling point for the replica lane has drifted since a previous test. If the optimal sampling point has drifted for the replica lane, adjustments are made to the sampling point of the replica lane and to the sampling points of the data lanes.
