Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message indicating a resource configuration for uplink and downlink transmissions. The UE may determine an uplink buffer threshold for a modem buffer of the UE based on the resource configuration. The UE may transmit, to the base station, a feedback request message requesting that the base station provide feedback for at least one previously transmitted uplink packet based on a comparison of an amount of previously transmitted uplink data and scheduled uplink data stored in the modem buffer relative to the uplink buffer threshold. The UE may receive, based on transmitting the feedback request message, a feedback response message corresponding to a first previously transmitted uplink packet of the at least one previously transmitted uplink packet.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may determine to discard a number of packets from a plurality of packets included in a packet stream. The plurality of packets may be associated with a context. The wireless communication device may determine that the number of packets to discard does not satisfy a threshold associated with the context. The wireless communication device may discard the number of packets. The wireless communication device may transmit the plurality of packets after discarding the number of packets based at least in part on the determination that the number of packets does not satisfy the threshold. Numerous other aspects are provided.

Abstract: Methods and equipments provide mechanisms for delivering out-of-order PDCP PDUs to the PDCP sublayer. In a user equipment configured for dual connectivity between LTE and NR, upon delivering at least one out-of-order PDCP PDU from the RLC sublayer to the PDCP sublayer, a PDCP reordering timer may be initialized. To prevent discarding of LTE PDCP PDUs while the RLC sublayer is performing a retransmission procedure, prior to expiration of the PDCP reordering timer, the out-of-order LTE PDCP PDUs mapped to decoded LTE RLC PDUs may be delivered from the RLC sublayer to the PDCP sublayer without reordering thereof. When the PDCP reordering timer expires, any LTE PDCP PDUs mapped to missing LTE RLC PDUs may be discarded.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a resource grant for an uplink transmission of uplink information on a logical channel. The uplink information may be stored in an uplink buffer. The UE may initiate a buffer status report retransmission timer in response to receiving the resource grant. The UE may determine that the resource grant allocates resources that are sufficient to transmit a portion of the uplink information that satisfies a threshold. The UE may stop the buffer status report retransmission timer in response to the determining.

Abstract: Methods, systems, and devices for wireless communication are described. Different robust header compression (RoHC) schemes may be used when a change in a header extension flag between packets of a communication session is determined. For example, a transmitting device may determine a value of a header extension flag in a packet has changed with respect to header extension flags in preceding packets. Upon detecting the change in the header extension flag, the device may compress the header using different RoHC schemes. For instance, the device may compress the header by reverting to an initialization and refresh (IR) state. Additionally or alternatively, the device may compress the header using a compression profile that refrains from compressing a certain portion of the header. In some cases, the RoHC scheme used for compressing the header may be based on how frequently the value of the extension flag changes between packets.

Abstract: A method and apparatus for prioritizing data packets when stateful compression is enabled for wireless communications is disclosed. For example, the aspects include receiving a plurality of data packets scheduled in a first order for transmission. The described aspects further include prioritizing one or more data packets of the plurality of data packets as one or more prioritized data packets, each prioritized data packet being scheduled in an order for transmission different from the first order for transmission. The described aspects further include compressing one or more unprioritized data packets of the plurality of data packets into one or more compressed unprioritized data packets. The described aspects further include scheduling the one or more prioritized data packets and the one or more compressed unprioritized data packets in a second order for transmission, the second order differing from the first order.

Abstract: Methods, systems, and devices may implement a header repair mechanism to deal with a loss of successive compressed headers (e.g., due to radio interface). The present methods and apparatus exploit the fact that once a correct timestamp (TS) from a previous decompression success (called "last successfully decomp_TS") is known, another (e.g., a subsequent) TS should be in the form: last successfully decomp_TS + n*min_TS_STRIDE, where n is a positive integer if the estimated sequence number (SN) is higher than the last successfully decompressed SN, and a negative integer if the estimated SN is lower than the last successfully decompressed SN, and min_TS_STRIDE is the expected minimum TS increment, which is known and directly related to the medium sample rate and frame rate, for example.

Abstract: Methods and devices are disclosed for managing diversity tune-away on a wireless communication device configured with at least two radio frequency (RF) receive resources associated with a connection in a high speed data network. The wireless device may monitor data communications and downlink channel conditions in the high speed data network, and determine whether a diversity tune-away mode has been entered. Upon determining that the diversity tune-away mode has been entered, the wireless device may perform a deliberate acknowledgment procedure by ignoring normal error detection for received data and sending an acknowledgment message for the received data to the high speed data network. The wireless device may determine whether the diversity tune-away mode has ended, and in response to determining that the diversity tune-away mode has ended, and halt the deliberate acknowledgment procedure in response to determining that the diversity tune-away mode has ended.
