Abstract: Methods, systems, and devices for wireless communication are described. A base station may receive a first measurement report from a user equipment (UE) that includes an indication of a measurement parameter associated with a first beamformed reference signal. The base station may receive additional measurement reports from the UE for additional base stations. The additional measurement reports may include an indication of measurement parameters associated with additional beamformed reference signals transmitted by the additional base stations. The base station may identify a location of the UE based on the first measurement report and the additional measurement report. Alternatively, the UE may transmit multiple beamformed sounding reference signals to multiple base stations, and a single base station may identify a location of the UE based on multiple reports collected from the multiple base stations.

Abstract: A unified frame structure for communicating in a synchronous and slotted mesh network is provided. Nodes within the mesh network are designated as primary and secondary nodes. For each transmission, a primary node may first send scheduling information to secondary nodes associated with the primary node. The receiver of the scheduled link may send a clear-to-send signal. For uplink scheduled transmissions, the receiver is the primary node. For downlink scheduled transmissions, the receiver is a secondary node. The transmitter of the scheduled link may receive the CTS signal from one or more proximate receivers, including a receiver associated with the scheduled transmission as well as other receivers not associated with the scheduled transmission. The transmitter of the scheduled link may estimate the signal to interference-plus-noise ratio of other links that are of higher priority and may then determine whether to yield or power back off the scheduled transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a number of beam directions that satisfy a transmission power condition. The UE may select a beam direction for a random access signal by choosing one of the beam directions that satisfies additional criteria, such as transmitting a random access message at the next opportunity. The transmission power may be selected based on a target receive power and a path loss for the selected beam. In some cases, if the sum of the path loss for a beam direction and the target receive power exceeds a maximum transmission power by more than a predetermined amount, the random access signal will not be transmitted using that beam. In some cases, if a response to the random access is not received, a different beam direction may be selected, the transmission power may be increased, or both.

Abstract: Methods, systems, and devices are described for wireless communications. A recipient device may receive a session initiation request from an originator device. The recipient device may support a first fragmentation configuration that supports inclusion of multiple data fragments per transmission data unit. The recipient device may determine to use a second fragmentation configuration in place of the first fragmentation configuration, where the second fragmentation configuration supports inclusion of fewer data fragments per transmission data unit than that supported by the first fragmentation configuration. The recipient device may then transmit a session initiation response indicating use of the second fragmentation configuration.

Abstract: A base station may determine a Doppler metric associated with a wireless channel and a user equipment (UE). The Doppler metric may be determined from received information related to Doppler effects measured by the UE or from directly measured Doppler effects associated with uplink data received from the UE. Based on the determined Doppler metric, the base station may select one or both of a reference signal (RS) density and a channel estimation technique for the wireless channel and associated UE. The base station may transmit an indication of the RS density to the UE. Downlink data bursts and uplink data bursts may include RSs and data according to the indicated RS density. Further, the base station may transmit to the UE, an indication to communicate using the selected wireless channel estimation technique.

Abstract: A user equipment (UE) may transmit a random access message to a wireless node using multiple symbols. The random access message may include repetitions of a random access sequence weighted by a spreading code. For example, a random access sequence may be weighted using different elements of the spreading code, where a first repetition may be weighted with a first element and a second repetition may be weighted using a second element. The weighted random access signals may be spread over multiple symbols and transmitted to the wireless node as the random access message. In some cases, a spreading code may include values of one and negative one, and may correspond to a number of symbols used to transmit the random access message. The spreading code may further indicate a downlink transmission beam identification (ID) associated with desirable reception qualities at the UE.

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.
