Abstract: Methods and apparatuses for downlink data buffering considering cross carrier scheduling in a wireless communication system are disclosed herein. In one method, the UE receives configuration of a first serving cell and a second serving cell from a network. The UE receives and/or monitors a first PDCCH transmitted on a scheduling CORESET of the second serving cell, wherein the first PDCCH schedules a first PDSCH transmitted on the first serving cell. The UE receives and/or monitors a second PDCCH transmitted on a scheduling CORESET of the second serving cell, wherein the second PDCCH schedules a second PDSCH transmitted on the second serving cell. The UE receives and/or buffers the second PDSCH via a TCI state used for PDCCH quasi co-location indication of the CORESET with the lowest CORESET-ID in the latest slot in which one or more CORESETs are configured for the UE, before the UE decodes successfully the second PDCCH. The UE does not receive and/or buffer the first PDSCH before the UE decodes successfully the first PDCCH.

Abstract: Facilitation detection of control channels with different transmission time intervals (TTIs) in wireless communications systems is described herein. In one example, a computer-implemented method comprises: monitoring, by a mobile device comprising a processor, a first control channel in the beginning of a first TTI; and receiving, by the mobile device, a first downlink control information (DCI) on the first control channel in the first TTI, wherein information of the first DCI indicates a pattern of a second TTI associated with a second control channel, and wherein the second control channel occurs later than the first control channel and the second TTI is shorter than the first TTI. The computer-implemented method can also comprise determining, by the mobile device, whether to monitor the second control channel of the second TTI based on the information of the first DCI.

Abstract: Control structures and techniques for transmission time interval (TTI) shortening in wireless communication systems are provided. Exemplary techniques can comprise establishing a UE device connection to a base station having a first TTI, wherein the UE device is configured to employ TTI shortening and has a second TTI different from the first TTI and monitoring a first short physical downlink control channel (PDCCH) region for a scheduled downlink (DL) transmission via the second TTI, wherein a time distribution associated with multiple second TTIs within the first TTI is determined based on a control format indicator (CFI) value indicated via the first TTI. Exemplary techniques can further comprise receiving a DL transmission via the second TTI and transmitting a hybrid automatic repeat request (HARD) acknowledgement (ACK) (HARQ-ACK) feedback on an associated UL channel for HARQ-ACK feedback, wherein for a number of DL transmissions via the second TTI within one of the first TTI on the associated DL, a number of associated UL channels for HARQ-ACK feedback occur within the same one of the first TTI on the associated UL. Further control structures and techniques for TTI shortening for wireless communication systems are described.
