  • Publication number: 20240284218
    Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC). The UE determines if the UE is operating in carrier aggregation (CA) mode having a first CC in a first frequency band and a second CC in a second frequency band. When the UE is operating in CA with a first CC in the first frequency band and the second CC in the second frequency band, the UE determines a span pattern for PDCCH symbols being received on the first and second CC and selects a PDCCH monitoring type based on, at least, the span pattern. A UE also determines if a first CC and a second CC of a CA combination are collocated and selects a PDCCH monitoring type based on, at least, the determination of whether the first and second CC are collocated.

  • Publication number: 20240106617
    Abstract: Systems and methods provide multiple cell activation. A user equipment (UE) receives, from a wireless network, a command to activate multiple cells simultaneously. In response, the UE initiates cell activation procedures for the multiple cells. The cell activation procedures include waiting for an active transmission configuration indicator (TCI) indication. The UE monitors for the active TCI indication on any of the multiple cells. In response to receiving the active TCI indication on a first cell of the multiple cells, the UE determines one or more second cells of the multiple cells that share a same spatial relationship with the first cell according to one or more predetermined rule, and autonomously continues the cell activation procedures for the first cell and the one or more second cells.

  • Patent number: 11792881
    Abstract: Systems and methods are provided for a user equipment (UE) to perform frequency offset (FO) delta tracking. For an anchor component carrier (CC), the UE wakes up to perform tracking updates on a plurality of successive DRX cycles. For the non-anchor CC, the UE determines a minimum update interval ?tupd, and schedules wake-ups on a first subset of the plurality of successive DRX cycles based on the minimum update interval ?tupd. For the first subset of the plurality of successive DRX cycles with scheduled wake-ups, the UE performs the tracking updates on the non-anchor CC and updates an FO delta between the anchor CC and the non-anchor CC. For a second subset of the plurality of successive DRX cycles without the scheduled wake-ups on the non-anchor CC, the UE applies the FO delta to correct for a frequency error.

  • Patent number: 11765732
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to communicate with a base station on different channels or messages with different processing timelines. In order to prevent a collision between processing communications associated with the different length TTIs, the UE may drop one or more communications on corresponding channels with longer processing timelines to receive and/or process the transmission on the channel with a shorter processing timeline. Additionally, the UE may transmit uplink control information (UCI) for the one or more dropped communications, where the UCI may include hybrid access request (HARQ) acknowledgement/negative acknowledgement (ACK/NAK) feedback, channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), etc. If a downlink transmission is dropped, the UE may transmit a NAK message. Alternatively, if an uplink transmission is dropped, the UE may transmit at least a portion of the UCI.

  • Patent number: 11743840
    Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems may support communication between a user equipment (UE) and a base station on multiple carriers (i.e., carrier aggregation). In some cases, the UE may be scheduled to transmit uplink signals on the different component carriers during transmission time intervals (TTIs) that have different durations. In such cases, it may be appropriate for the UE to determine a maximum transmit power limit relating to the amount of power used for the uplink transmissions on the multiple carriers. As described herein, the UE may identify one of the component carriers as a reference component carrier, and the UE may determine the maximum transmit power limit for a duration of a TTI associated with the reference component carrier. The UE may then transmit on the multiple carriers in compliance with the maximum transmit power limit.
