    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit two or more connection requests prior to expiration of a UE connection response window. In some examples, the UE may re-set a UE connection response window each time the UE transmits a connection request. In some examples, the base station and UE may set their respective connection response windows after the UE transmits connections requests in a set of consecutive transmission opportunities. In some examples, the base station and UE may set their respective connection response windows based at least in part on a first available transmission opportunity. In some examples, the UE may include an indication of a position in a transmission sequence in the connection response, and the base station may set the UE connection response window based at least in part on the indication.

    Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for adjusting communication timings of beams (e.g., of beam pair links) within a beam timing advance group (TAG). In some cases, a base station may determine that transmission timing at a UE may be misaligned between multiple beams. The base station may configure a set of beams into a beam TAG, and may send a timing advance (TA) command for the beam TAG. A common timing reference value may be identified based on the TA command. UEs performing uplink transmissions may determine a TA value for the beam TAG based on the common timing reference value, and may adjust a communication timing for one or more of the beams within the beam TAG based at least in part on the common timing reference value and the timing advance value.

    Abstract: Methods, systems, and devices for wireless communication are described. A base station may select a waveform configuration and a resource for a user equipment (UE) to use to transmit a random access channel (RACH) message 3 (msg3). The base station may transmit a value indicative of the waveform configuration to the UE, wherein the waveform configuration is further indicative of the selected resource. The UE may receive the value indication and identify the waveform configuration. Based on the waveform configuration, the UE may identify the resource to use to transmit the RACH msg3. The UE may transmit the RACH msg3 using the resource and according to the waveform configuration.

    Abstract: Methods, systems, and devices for wireless communication are described in relation to a Multiple Subscriber Identify Module (MSIM) user equipment (UE). The UE associated with multiple network subscriptions may determine a first timing of a first set of paging occasions associated with a first network subscription of the multiple network subscriptions, wherein the first network subscription is associated with a first network; determine a second timing of a second set of paging occasions associated with a second network subscription of the multiple network subscriptions, wherein the second network subscription is associated with a second network; compare the first timing and the second timing; detect a paging time adjustment condition based on the comparing; and based on the detecting, transmit to the first network, the second network or both a random access signal using a random access resource configured to convey a paging time adjustment request.

    Abstract: Techniques are provided for power control in directional beam environments. A user equipment (UE) may determine one or more power parameters on a beam-by-beam basis. Each directional uplink transmission beam in a communication link between the UE and the base station may be independently controlled using these beam-specific power parameters. Examples of these beam-specific power parameters may include a maximum output power for a given directional uplink transmission beam and a difference between the maximum output power for the given directional uplink transmission beam and an estimated transmit power for the given directional uplink transmission beam. The UE may report one or more of these beam-specific power parameters to a base station using a beam-specific report.

    Abstract: A UE may receive a beam modification command that indicates a set of transmit beam indexes corresponding to a set of transmit beams of a base station, and each transmit beam index of the set of transmit beam indexes may indicate at least a transmit direction for transmitting a transmit beam by the base station. The UE may determine a set of receive beam indexes corresponding to receive beams of the UE based on the set of transmit beam indexes, and each receive beam index of the set of receive beam indexes may indicate at least a receive direction for receiving a receive beam by the UE. The UE may receive, from the base station, a signal through at least one receive beam corresponding to at least one receive beam index included in the set of receive beam indexes.
