摘要： Aspects are provided allowing a MSIM UE to transmit a controlled pattern of fake HARQ-ACK and a controlled RLC status report in response to un-decoded data transmissions from a base station, while suspending SRS antenna switching during performance of an activity in a different network subscription, in order to relieve MCS penalties in response to such suspension while minimizing RLC holes. The UE sends a plurality of SRSs to a base station in a first network using a first SIM of the UE, where each of the SRSs is sent using a different antenna. The UE suspends SRS transmission from the different antennas while performing an activity in a second network using a second SIM of the UE. The UE sends a HARQ-ACK to the base station while the SRS transmission is suspended in response to at least one of a plurality of un-decoded data transmissions from the base station.

摘要： Certain aspects of the present disclosure provide techniques for avoiding scheduling outages at a scheduler of a base station. A method that may be performed by a user equipment (UE) includes receiving, via a first subscription, one or more packets of a plurality of packets from a wireless node during a first duration of a discontinuous reception (DRX) mode, detecting at least one missing packet of the plurality of packets, transmitting a request to the wireless node, requesting resources for transmitting a report associated with the plurality of packets, and receiving the at least one missing packet during the first duration of the DRX mode based, at least in part, on the transmission of the request.

摘要： Aspects of the present disclosure relate to optimization of packet processing when packets are received out of order in sequence. For example, a user equipment (UE) may determine whether a difference between a sequence number of a first packet and a sequence number of a second packet received subsequent to receiving the first packet exceeds a sequence jump threshold. The UE may disregard the second packet from processing in response to at least determining that the difference is greater than the sequence jump threshold. The UE may receive and process a plurality of packets respectively associated with a plurality of sequence numbers that are greater than the sequence number of the first packet and less than the sequence number of the second packet.

摘要： Certain aspects of the present disclosure relate to methods and apparatus for improving MT call performance upon RACH failure for page response using communications systems operating according to LTE and new radio (NR) technologies in conjunction with other legacy technologies. For example, certain aspects provide a method for wireless communication by a user equipment (UE). The method generally includes receiving a page from a network for a mobile terminated (MT) call, determining a random access procedure by the UE corresponding to a response to the page failed, and transmitting, in response to the determining, an indication to the network after initiating a cell reselection procedure that the page was received by the UE.

摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may receive a priority list associated with preferred radio frequencies from a serving base station. In certain aspects, each radio frequency of the preferred radio frequencies associated with a first set of base station may operate on a first RAT. In certain other aspects, the apparatus may determine if the UE is able to reselect to the first RAT. In certain other aspects, the apparatus may perform a rank-based cell reselection procedure based on signal strength when the UE is unable to reselect to the first RAT.

摘要： A wireless communication device is described. The wireless communication device includes a memory and a processor in electronic communication with the memory. The processor is configured to determine a packet data convergence protocol (PDCP) packet count corresponding to a last radio link control (RLC) packet received in-sequence. The processor is also configured to detect a missing PDCP packet based on a comparison of the PDCP packet count and a sequence number of a last PDCP packet received in-sequence.

摘要： A multi-subscriber identity module (SIM) wireless communication device performing early camping in initial cell selection or reselection may detect an active communication on a modem stack associated with a first SIM, and a condition requiring initial cell selection/reselection on a modem stack associated with a second SIM. In response to receiving a paging message for the second SIM, the wireless communication device may trigger a radio resource to tune to a frequency of an identified target cell of the second SIM, receive a first portion of system information broadcast by the identified target cell, and determine whether initial cell selection/reselection to the identified target cell is complete. In response to determining that initial cell selection/reselection to the identified target cell is not complete, the wireless communication device may save the received paging message, and raise a priority level for the activity on the modem stack associated with the second SIM.
