Abstract: Certain aspects of the present disclosure relate to methods and apparatus for transitioning between short DRX and long DRX cycles based on service type to improve performance (e.g., reduce delay) while limiting power consumption. In one example, the UE switches to a long DRX cycle after a DRX Short Cycle Timer, or drxShortCycleTimer, expires. The UE may also switch to a long DRX if the UE receives long DRX MAC control element (CE) from a gNB. In another example, a gNB may configure a radio bearer from a set of radio bearers (data radio bearer (DRB) and/or signal radio bearer (SRB)), denoted by S, to trigger the UE to enter a short DRX cycle.

Abstract: Certain aspects of the present disclosure propose methods for determining power level of one or more transmitters based on a power level of a primary transmitter when the transmitters are located in close proximity of each other. The power levels may be determined such that a combined power of all the transmitters is compliant with regulatory radio frequency (RF) safety requirements. For certain aspects, power level of the lower priority transmitters may be determined utilizing one or more look-up tables. For another aspect, power level of the lower priority transmitters may be calculated using an algorithm based on the power level of the priority transmitter. In aspects, the power level of lower priority transmitters and the time duration for which the transmitters are active may be selected dynamically so that the time averaged power of the transmitters for a defined period of time falls below the RF exposure limit.

Abstract: Systems, methods, and apparatus are described that provide for communicating coexistence messages over a multi-drop serial bus. A method performed at a device coupled to a serial bus includes receiving first coexistence information directed to a first device coupled to the serial bus, generating a first coexistence message representative of the first coexistence information, converting the first coexistence message to obtain a first datagram including the first coexistence information, and transmitting the first datagram to the first device over the serial bus. The first coexistence message may be configured for communication through a point-to-point data link. The first datagram may be configured according to a first protocol associated with the serial bus.

Abstract: Systems, methods, apparatuses, and media are provided for recovery of information from redundancy version packets in systematic encoding environments when a redundancy version packet containing primarily systematic information may be corrupted. A plurality of redundancy version packets may be received at a user equipment device from a transmission device. Each redundancy version packet of the plurality of redundancy version packets may be based on a same group of information bits. A first redundancy version packet of the plurality of redundancy version packets may contain more bits of the same group of information bits than do the other redundancy version packets of the plurality of redundancy version packets. The same group of information bits may be recovered based on one or more second redundancy version packets of the plurality of redundancy version packets but not based on the first redundancy version packet.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless devices (e.g., dual subscriber identity modules (SIM) devices) may support two subscriptions such that while one subscription is actively transmitting or receiving, the other subscription is put on standby. The wireless device may identify collisions in time between monitored paging messages associated with the first and second subscriptions. Accordingly, the wireless device may modify a radio access technology (RAT) priority setting for one of the subscriptions, such that paging messages may be received via a RAT different that the RAT used for the other subscription (e.g., following a cell reselection procedure performed according to the modified RAT priority). Operation using a modified RAT priority setting may be referred to as a fallback mode, which may be exited upon expiration of a timer. Additionally, discontinuous reception (DRX) durations associated with the RATs used for subscription paging may be reduced.

The obp may be indicated on a per UE basis, a per band basis, a per band combination basis, a per band, per band combination basis; and/or a per CC, per band, per band combination basis. Each band combination may indicate a combination of a numerology, a layer and a bandwidth. In another example, a plurality of basebands may be defined, each baseband indicating a combination of a numerology, a layer and a bandwidth.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may detect a collision of paging messages for a first subscription and a second subscription of the wireless device during a paging processing duration, the first receive chain including at least one antenna path. The wireless device may determine that, in a connected mode, it is configured to operate a second receive chain with one or more additional antenna paths, and may allocate, for a subsequent instance of the paging processing duration, the first subscription to one of the first receive chain or the second receive chain, and the second subscription to the other of the first receive chain or the second receive chain. The wireless device may monitor, during the subsequent instance of the paging processing duration, for a first paging message and a second paging message using the first and second receive chains.

Abstract: Methods and apparatus are provided for quick recovery of missed packets after a user equipment (UE) tunes back to a first network after tuning away from the first network. The UE may determine that a trigger event has occurred, and in response to the determination, modify a negative acknowledgement (NACK) timing configuration from a default configuration. Modifying the NACK timing configuration may include using an aggressive NACK timing configuration for a configurable period of time, in response to detecting a trigger event. The trigger event may include detecting missed packets after a tune back, unavailability of sufficient memory to hold packets until a gap created by missed packets may be filled, or tuning back to a network.

Abstract: Aspects of the disclosure relate to dual connectivity reporting. In one example, a dual connectivity communication is established, which includes a communication with a master node according to a first radio access technology (RAT), and a communication with a secondary node according to a second RAT. A change in measurement capability is then detected, and subsequently reported to the master node and/or secondary node. In another example, a scheduling entity establishes a first or second communication of a dual connectivity communication with a scheduled entity. The first communication is established according to a first RAT when operating as a master node, and the second communication is established according to a second RAT when operating as a secondary node. An indication is then received from the scheduled entity of a change in measurement capability, and the first and/or second communications are reconfigured in response to the change in measurement capability.
