Abstract: Methods and apparatus for wireless communication include monitoring, by a user equipment, a signal quality value from at least one of a serving cell or a target cell. The methods and apparatus further include determining, at an expiration of an internal time to trigger (TTT) less than a network-configured TTT, that at least one of the signal quality value from the serving cell is below a serving cell threshold value, or the signal quality value from the target cell is above the signal quality of the serving cell by a comparative threshold value. Moreover, the methods and apparatus include triggering generation of a measurement report based on the determination.

Abstract: Methods and apparatus for wireless communication include applying a compression algorithm to a data flow, and evaluating a level of compression of the data flow resulting from the applying of the compression algorithm. Further aspects include determining when the level of compression of the data flow is below a first threshold, and disabling compression of the data flow when the level of compression is below the first threshold. Additional aspects include determining when the level of compression of the data flow is above a second threshold, and enabling compression of the data flow when the level of compression is above the second threshold, wherein the second threshold is greater than the first threshold.

Abstract: The described aspects include a user equipment (UE) apparatus and corresponding method of performing a High-Speed Uplink Packet Access (HSUPA) transmission. The aspects include determining availability of information for transmission while the UE is in a Cell_FACH state and an idle mode. Further, aspects include generating a message including a scheduling information (SI) indicator during a collision resolution phase of an uplink procedure when SI data is allowed to be transmitted during the collision resolution phase, wherein the SI indicator identifies whether the SI data is included in a Medium Access Control-i (MAC-i) Packet Data Unit (PDU). Additionally, the aspects include transmitting the message, destined for a network component, during the collision resolution phase. The described aspects also include a corresponding network component and method for receiving the message and unambiguously determining presence of SI data in the MAC-i PDU.

Abstract: Certain aspects of the present disclosure provide techniques for handling coordinated beamforming in wireless communications systems. An example method performed by a first access point (AP) generally includes outputting, for transmission to a second AP, at least one of a first indication that the first AP supports spatial reuse of transmission resources or a second indication that the first AP supports asymmetric coordinated beamforming (CBF); and outputting, for transmission, signaling to one or more stations (STAs) supported by the first AP without intent to form nulls directed toward other STAs supported by the second AP.

Abstract: The disclosure relates in some aspects to enabling a user terminal (UT) to obtain information about nearby cells and any beams generated by nearby cells. For example, a network can send a neighbor cell list to UTs, where the list identifies the cells in that neighborhood and provides information about any beams generated by those cells. Thus, a UT can learn the neighboring beams/cells that the UT can reselect to if the current beam/cell becomes weak. In some aspects, the UE can learn the attitude (e.g., pitch, roll, yaw, or any combination thereof) profile of neighboring satellites as well as the pointing angles and the ON-OFF schedules of their beams. In some aspects, the UT can learn a start angle and a span for a satellite and use this information to identify a satellite the UT can reselect to if the current beam/cell becomes weak.

Abstract: The disclosure relates in some aspects to managing paging area information for a user terminal (UT) and connection signaling. In some aspects, paging area information is provided for an idle UT by defining a default paging area code (PAC) that is known by the network and the UT. In some aspects, paging area information is communicated via connection signaling. In some aspects, connection signaling may be used to force a UT to invoke an update procedure (e.g., a reconnection).

Abstract: The disclosure relates in some aspects to location reporting and paging for satellite communication. In one aspect, the disclosure relates to a user terminal (UT) sending a message to report information about the UT's location. A threshold may be used to control whether (e.g., when) the UT reports its location. The location information may be used to enforce area (e.g., country) restrictions for the UT. In one aspect, the disclosure relates to forwarding paging messages between network access controllers. For example, a network access controller that is not able to page a UT may forward a paging message to another network access controller. In one aspect, the disclosure relates to a list of paging areas that indicates where a UT need not perform a paging area update.

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: 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).
