    摘要: Various aspects include a method of providing, by a network to a UE device, a transmission grant. The method includes initiating a process to provide the transmission grant for a transmission within a particular time. The method includes verifying that there is no cancellation indication that overlaps the particular time. The method includes providing, based on the verification, the transmission grant to the UE device. The method includes determining whether there is no transmission that overlaps with a cancellation window associated with a monitoring occasion, and based on the determination, skipping the monitoring occasion. Also disclosed a system for providing a transmission grant to the UE device.

    摘要: A method for performing PDCCH monitoring of component carriers (CCs) in a carrier aggregation scheme that aggregates a first CC and a second CC. In some embodiments, the method includes: calculating a first monitoring occasion start time for a monitoring occasion of the first CC, wherein the first monitoring occasion start time is expressed as a first symbol-index value; calculating a second monitoring occasion start time for a monitoring occasion of the second CC, wherein the second monitoring occasion start time is expressed as a second symbol-index value; and generating a schedule for the monitoring occasion of the first CC and the monitoring occasion of the second CC based on an ascending order of the first monitoring occasion start time and the second monitoring occasion start time.

    摘要: A system and method for setting blind detection and control channel element monitoring limits in a carrier aggregation scheme. In some embodiments, the method includes: receiving, by a network from a first user equipment (UE), a declaration of capabilities of the first UE; sending, by the network, to the first UE, a first search space (SS) configuration for a first component carrier in a carrier aggregation (CA) scheme; and sending, by the network, to the first UE, a second search space configuration for a second component carrier in the carrier aggregation scheme. The first search space configuration may define a first set of monitoring occasions, the second search space configuration may define a second set of monitoring occasions (MOs), and an aligned span pattern, corresponding to the first set of monitoring occasions and the second set of monitoring occasions, may comply with the declaration of capabilities of the first UE.

    摘要: A method of managing multiple transmission and reception point (M-TRP) communications includes receiving, by a user equipment (UE), a plurality of PDSCH communications, wherein: a first subset of the plurality of PDSCH communications is associated with a first TRP, and a second subset of the plurality of PDSCH communications is associated with a second TRP different from the first TRP. The method further includes selecting a first set of one or more PDSCH communications to decode by applying a first management process for the first subset of PDSCH communications; selecting a second set of one or more PDSCH communications to decode by applying a second management process for the second subset of PDSCH communications; and decoding the first set of one or more PDSCH communications to decode and the second set of one or more PDSCH communications to decode.

    摘要: A system and a for dynamic uplink transmitter switching may include configuring, by a user equipment (UE), a first uplink (UL) transmission on one or more carriers out of at least three carriers; configuring, by the UE, a second UL transmission on the one or more carriers out of the at least three carriers; and scheduling, by the UE, an interruption time on one or more of the at least three carriers according to a predetermined criteria based on a state of transmit (Tx) chains for the first UL transmission and a state of Tx chains for the second UL transmission.
