摘要： Methods, systems, and devices for wireless communications are described. A wireless node may receive one or more data messages which may include a set of packets that may each be associated with a sequence number. The set of packets may be received with a gap in the set of sequence numbers, indicating missing packets. The wireless node may forward the set of packets to a processing layer of the wireless node. The wireless node may then accept, from the processing layer of the wireless node, a set of duplicate (DUP) acknowledgment (ACK) messages based on the set of packets being forwarded to the processing layer while having the gap in the set of sequence numbers. The wireless node may transmit, a subset of the set of DUP ACKs rather than all of the set of DUP ACKs to another wireless node, such as a base station.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, via a first connection of a dual connectivity mode, a first packet having a first sequence number. The UE may receive, via a second connection of the dual connectivity mode, a second packet having a second sequence number. The UE may determine, based at least in part on the first sequence number and the second sequence number, that the first packet is received out of order. The UE may maintain a packet order for reception of subsequent packets via the first connection or the second connection. The UE may drop the first packet based at least in part on the determination that the first packet is received out of order. Numerous other aspects are provided.

摘要： Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that data is buffered for transmission via a first logical channel that does not have a valid scheduling request configuration. The UE may transmit, via a scheduling request resource of a second logical channel that has a valid scheduling request configuration, a scheduling request for resources to transmit the data buffered for transmission via the first logical channel. Numerous other aspects are described.

摘要： A method of wireless communication by a user equipment (UE) includes receiving a number of uplink grants from a base station. The method further includes estimating a payload size for data to be transmitted from a UE buffer for a number of logical channels. The payload size corresponds to a sum of a number of data bytes to be transmitted and an amount of overhead bytes to be transmitted. The method still further includes determining a subset of the number of uplink grants to use for uplink transmission based on reducing a total padding size associated with transmitting the payload size, for each combination of the number of uplink grants. The method also includes transmitting the data from the UE buffer within a number of transport blocks, to the base station. The number of transport blocks corresponds to the subset of the number of uplink grants.

摘要： Apparatuses and methods for a wireless communication device having a first Subscriber Identity Module (SIM) and a second SIM to manage communication via the first SIM and the second SIM are disclosed. The method can include, but is not limited to, sending a first message including an indication of an extended signaling capability, receiving a second message including an inquiry regarding the extended signaling capability, and sending a third message including extended capability information, responsive to receiving the second message.

摘要： In wireless communication, uplink communication by a wireless communication system user equipment may include providing data packets by a data source in the user equipment, detecting a pattern relating to uplink transmission of the plurality of data packets, and scheduling transmission of the plurality of data packets by the user equipment. One or more aspects of scheduling transmission of the plurality of data packets may be based on the detected pattern.

摘要： Various aspects of the disclosure relate to techniques for handling out-of-order grants. For example, upon detection of an out-of-order grant, the best scheduling policy for handing the out-of-order grants may be selected based on at least one traffic condition. In some aspects, a scheduling policy may involve canceling and regenerating out-of-order grants. In some aspects, a scheduling policy may involve reordering data units. In some aspects, a scheduling policy may involve designating a reorder time window.

摘要： Apparatuses and methods are described herein for a wireless communication device to request uplink grants associated with the first subscription using at least one Radio Frequency (RF) resource, including tuning away from the first subscription to the second subscription for a tune-away time interval, determining whether the tune-away time interval exceeds a threshold, transmitting at least one scheduling request associated with the first subscription for a throttled count in response to the tune-away time interval exceeding the threshold, wherein the throttled count is less than a default count, determining whether an uplink grant has been received in response to any of the at least one scheduling request transmitted within the throttled count, and initiating an uplink data Random Access Channel (RACH) process in response to not receiving the uplink grant.
