Abstract: Methods, systems, and devices are described for wireless communication. A user equipment (UE), for example, may determine a content size of an uncompressed buffer and a content size of a compressed buffer. The UE may then generate a buffer status report (BSR) based on the content sizes of the uncompressed buffer and the compressed buffer. Alternatively, a base station may receive a BSR based on a size of an uncompressed buffer of the UE. The base station may then receive a compressed packet from the UE and may determine a compression gain based on a size of the compressed packet and a size of a corresponding uncompressed packet. The base station may then adjust the received BSR based on the compression gain.

Abstract: Aspects of the present disclosure provide techniques for compressing data packets for cellular internet of things (CIoT) communications. An example method generally includes establishing at least one prefill buffer common to one or more UEs, wherein the prefill buffer includes a plurality of common strings, generating a compressed packet by finding matches to the common strings in at least one of a header portion or payload portion of the packet and associating identifiers with the common strings, and transmitting the packet.

Abstract: Methods, systems, and devices are described for wireless communication at a UE. In aspects, a receiver may receive a transmission requesting information about support for data compression. The receiver may determine parameters related to the types of supported data compression and communicate the information to the transmitting device. In some cases, the receiver may then receive a message from the transmitting entity that requests establishment of a data compression configuration. The receiver may respond with confirmation or rejection of the proposed compression configuration. If the configuration is confirmed, the transmitter and receiver may exchange compressed data packets according to the configuration. The devices may exchange status and control information related to the compression configuration (e.g., in a compression header of a compressed message or a separate status and/or control information message).

Abstract: Aspects of the present disclosure generally relate to wireless communications. In some aspects, a device may receive a first uplink grant for a first cell that uses a first component carrier, and may receive a second uplink grant for a second cell that uses a second component carrier. The device may determine at least one of: a number of subframes for which uplink data is transmitted on both the first cell and the second cell during a time period, or a resource block allocation associated with the first cell and the second cell. The device may drop at least one of the first uplink grant or the second uplink grant based at least in part on at least one of: a determination that the number of subframes satisfies a threshold number of subframes, or a determination that the resource block allocation satisfies a condition.

Abstract: Aspects of the present disclosure generally relate to wireless communications. In some aspects, a user equipment (UE) may determine whether to configure the UE for a first type of resource sharing or a second type of resource sharing between a first radio access technology (RAT) and a second RAT, wherein one or more UE resources are configured for use with the first RAT. The UE may reconfigure the one or more UE resources for use with the second RAT based at least in part on determining whether to configure the UE for the first type of resource sharing or the second type of resource sharing.

Abstract: A first method includes transmitting, to a network, an indication of a capability to operate in an uplink aggregation dual connectivity mode or in a fast switching dual connectivity mode; and receiving, from the network, a dual connectivity configuration for the UE based at least in part on the indication of the capability. A second method includes communicating with a first network access device; transmitting, to a second network access device, a request to perform fast switching from the first network access device to the second network access device; receiving, from the second network access device, a dual connectivity configuration for communicating with the second network access device; and communicating with the second network access device based at least in part on the dual connectivity configuration.

Abstract: Techniques are described herein to dynamically control a number of hybrid automatic repeat requests (HARQ) transmissions based at least in part on flow characteristics of a data flow. Data included in a transport block may be grouped into one or more data flows based on a variety of factors. A set of performance benchmarks may be associated with each data flow. Flow characteristics for each data flow may be measured. A network entity may determine a number of HARQ transmissions to be transmitted during a HARQ procedure based on measured flow characteristics satisfying the performance benchmarks. For example, if a performance benchmark is not satisfied by its associated flow characteristic, the network entity may request additional HARQ transmissions during the HARQ procedure.
