The present application relates to scheduling SSB measurements on SSB beams. In an example, a base station can transmit SSBs on SSB beams that form a serving cell. Depending on an SSB measurement on one of the SSB beams, a UE can schedule an additional SSB measurement on this SSB beam only or schedule SSB measurements on the different SSB beams.

Serving cell measurements in idle mode

The present application relates to devices and components including apparatus, systems, and methods for reference signal indication for idle or inactive user equipments.

Technologies for reference signal indication

Methods, systems, and devices for wireless communications at a user equipment (UE) are described. Aspects of the described techniques may include the user equipment measuring signal aspects for a plurality of respective receive beams for receiving communications associated with a synchronization signal block transmitted by a base station on a transmit beam. From the measured signal aspects, the UE may determine that a receive beam from the plurality of receive beams is a preferred beam for receipt of communications from the base station transmitted on the transmit beam. With the determined preferred beam, the UE may initiate a beam-sweeping procedure to re-measure the plurality of UE receive beams, where the UE measures the first UE receive beam before measuring others of the plurality of UE receive beams.

Virtual serving beam tracking in millimeter wave wireless systems

A method and apparatus of a device that switches bandwidth parts for a user equipment device and a base station is described. In an exemplary embodiment, the device receives an indication to switch to the bandwidth part for the user equipment on the wireless link from the base station. In addition, the device switches to the new bandwidth part for the user equipment. The device further signals that the switching to the new bandwidth part has occurred in a time period smaller than a predefined time period. The deice additionally communicates information on the wireless link using the new bandwidth part.

Methods and apparatus for radio resource control based bandwidth parts switching

A wake up signal scheme between a network and a user equipment (UE) operating in a Discontinuous Reception (DRX) state. The UE monitors a wake up signal (WUS) occasion to determine whether a WUS is received during the WUS occasion, when the WUS is received, determines whether the WUS identifies the UE, when the WUS is received and identifies the UE, monitors an OnDuration of a Discontinuous Reception (DRX) cycle corresponding to the WUS and when the WUS is not received or the WUS does not identify the UE, remains in a sleep state during the OnDuration corresponding to the WUS.

Wake-up signal for discontinuous reception operations

Apparatus, methods, and computer-readable media for facilitating UE beam selection based on service demands are disclosed herein. An example method of wireless communication includes determining to select an UL beam having a higher EIRP capability than an EIRP capability associated with a current beam for transmitting on UL when at least one of a target transmit power based on a TPC exceeds an EIRP capability associated with the current beam or when an amount of data in a buffer of the UE is greater than a data threshold. The example method also includes determining, upon determining to select the UL beam, a set of UL beams with an EIRP capability satisfying an EIRP capability threshold and a respective beamforming direction corresponding to a beamforming direction associated with the current beam, selecting one UL beam of the set of UL beams, and transmitting on UL on the selected UL beam.

User equipment beam selection based on service demands

A user equipment (UE) receives reference signals during a discontinuous reception (DRX) cycle to perform frequency and timing tracking or automatic gain control (AGC). The UE receives configuration information corresponding to a reference signal that is to be transmitted to a user equipment (UE) when the UE is in a first operating state, receives the reference signal from a cell of a network when the UE is in the first operating state, performs one of frequency and timing tracking or automatic gain control (AGC) using the reference signal and receives a signal from the cell during a time window that the UE is scheduled to utilize an active mode of data exchange processing.

Tracking reference signal enhancements for new radio

Systems and methods are provided for a user equipment (UE) to perform frequency offset (FO) delta tracking. For an anchor component carrier (CC), the UE wakes up to perform tracking updates on a plurality of successive DRX cycles. For the non-anchor CC, the UE determines a minimum update interval &#x394;t, and schedules wake-ups on a first subset of the plurality of successive DRX cycles based on the minimum update interval &#x394;t. For the first subset of the plurality of successive DRX cycles with scheduled wake-ups, the UE performs the tracking updates on the non-anchor CC and updates an FO delta between the anchor CC and the non-anchor CC. For a second subset of the plurality of successive DRX cycles without the scheduled wake-ups on the non-anchor CC, the UE applies the FO delta to correct for a frequency error.

Frequency offset delta tracking for NR connected mode discontinuous reception carrier aggregation

Methods and apparatus to facilitate user equipment beam selection based on service demands

A user equipment (UE) may monitor multiple beam pair links (BPLs) including a first BPL currently used by the UE to communicate with a network node (e.g., a base station), and a second BPL. The first BPL comprises a first network beam and a first UE beam, and the second BPL comprises a second network beam and a second UE beam. The UE may decide to switch beams from using the first BPL to using the second BPL based on signaling from the network node or autonomously. When the beam switch is made, the UE switches uplink (UL) transmission from over the first UE beam to over the second UE beam. After the beam switch is made, the UE transmits in the UL over the second UE beam using UL timing adjusted based on the first and second propagation delays.

Uplink timing compensation

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, for a candidate UE uplink beam, a transmit power due to a maximum permissible exposure (MPE) constraint; estimate, for the candidate UE uplink beam, a receive power for a base station based at least in part on the transmit power due to the MPE constraint; determine a target receive power for the base station; and select the candidate UE uplink beam as an active UE uplink beam based at least in part on the estimated receive power for the base station and the target receive power for the base station. Numerous other aspects are provided.

Uplink beam selection in millimeter wave subject to maximum permissible exposure constraints

Methods and apparatuses relate to sounding reference signal (SRS) transmit antenna selection in wireless communication systems. For example, a user equipment (UE) may select, from a set of antennas, a subset of antennas for SRS transmission based on at least one antenna selection parameter. The UE may further transmit, on an uplink communication channel, the SRS using the subset of antennas to a network entity. In some aspects, the at least one antenna selection parameter may include a reference signal receive power (RSRP) value, a signal-to-noise ratio (SNR) value, a spectrum efficiency value, and/or an SNR value and a channel correlation value.

Sounding reference signal (SRS) transmit antenna selection

Aspects of the present disclosure relate to wireless communications and, more particularly, to how to allocate transmission power for uplink transmissions on different component carriers.

Power allocation for uplink transmissions

Aspects of the present disclosure provide techniques for the user equipment (UE) to select a power management mode from a plurality of power management modes supported by the UE based on decoding of a portion of the downlink subframe. For example, when the UE receives a subframe from a base station, the UE may decode a control channel region of the subframe to determine whether the subframe includes a channel grant allocated to the UE. If no channel grant is included in the subframe, the UE may select a power management mode for the UE from the plurality of power management modes supported by the UE that maximizes the UE's sleep opportunities while balancing the deficient performance costs.
