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: Methods, systems, and devices are described for wireless communication at a user equipment (UE). In some examples, the UE may identify an initialization and refresh (IR) packet at the radio link control (RLC) layer based the size of the IR packet, where the IR packet comprises a larger ciphered PDU size than a compressed RoHC packet. Accordingly, once the UE identifies the received packet as an IR packet, the UE may attempt to decipher the IR packet using one or more HFN offset values. In one example, the UE may determine whether the IR packet is deciphered correctly based on cyclic redundancy check (CRC) value of the deciphered IR packet. As a result, the present disclosure allows the UE to re-synchronize with the transmitting device by at least one of incrementing or decrementing an HFN value at the receiving device.
Abstract translation: 描述了用于用户设备（UE）的无线通信的方法，系统和设备。 在一些示例中，UE可以基于IR分组的大小来识别在无线电链路控制（RLC）层处的初始化和刷新（IR）分组，其中IR分组包括比压缩的RoHC分组更大的加密的PDU大小。 因此，一旦UE将接收的分组识别为IR分组，则UE可以尝试使用一个或多个HFN偏移值来解密IR分组。 在一个示例中，UE可以基于解密的IR分组的循环冗余校验（CRC）值来确定IR分组是否被正确解密。 结果，本公开允许UE通过在接收设备处递增或递减HFN值中的至少一个来与发送设备重新同步。

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.

Abstract: In one aspect, a method of wireless communication includes determining a number of bytes in a compressed queue and a number of bytes in an uncompressed queue. The method also includes transmitting a buffer status report (BSR) indicating at least the number of bytes in the compressed queue. The method includes receiving an uplink grant indicating one or more uplink grant resources and a number of bytes allocated for the one or more uplink grant resources. The method also includes generating a transport block (TB) based on the uplink grant and the BSR and from data of at least the compressed queue, wherein the TB includes one or more compressed packets and one or more uncompressed packets. The method further includes transmitting a PUSCH transmission including the TB during an uplink grant resource of the one or more uplink grant resources. Other aspects and features are also claimed and described.

Abstract: A recovery mechanism for robust header compression (ROHC) is disclosed for wireless communication systems. The ROHC recovery mechanism may allow a receiver and/or transmitter in the wireless systems to establish or reestablish a context of a packet transmission session when an initialization and refresh message is lost. In the ROHC recovery mechanism, upon receiving a compressed packet that is not associated with a context, a receiver sends a message to a transmitter suggesting the transmitter to transition to another mode. Upon receiving a subsequent packet transmission that is not associated with a context, the receiver sends another message indicating that a context has not been established or has been lost. The transmitter may then send the receiver necessary information to establish a context for the packet transmission session.

Abstract: Apparatus and methods, in one or more aspects, provide for status report management of received data packets at a wireless device. The wireless device may determine that a first status report, generated in response to identifying a number of missing data packets within a sequence of a plurality of data packets received at the UE, includes information associated with fewer than the number of missing data packets. The wireless device may transmit the first status report. The wireless device may also disable a status prohibition timer in response to the transmitting based on the determination. The wireless device may transmit a second status report including information associated with a remainder of the number of missing data packets not included in the first status report.

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: 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.
