Disclosed are enhancements for a Mode 2 TPMI list indication, including TPMI capability reporting design, TPMI list enhancement for four-port partial coherent UE, and TPMI list enhancement for four-port non-coherent UE.

Full power transmission mode 2 TPMI list signaling enhancement

An invention to perform a method of cell measurement in a wireless network, wherein the wireless network comprises a plurality of frequency layers, the invention configured to: determine a Measurement Gap Length, MGL, for each one of the plurality of frequency layers operational in the wireless network; determine a gap bitmap to indicate a measurement gap availability in a time sequence for each one of the plurality of frequency layers of the wireless network; and transmit gap assistance information for each one of the plurality of frequency layers of the wireless network to a User Equipment, wherein the gap assistance information comprises at least the determined Measurement Gap Length and the determined gap bitmap.

Measurement design for next radio (NR) and long term evolution (LTE)

Some embodiments include an apparatus, method, and computer program product for simultaneous multiple secondary cell (SCell) fast activation in a wireless communications system. Some embodiments include a user equipment (UE) that can simultaneously activate multiple SCells. In some embodiments, after receiving an activation command, the UE can receive two or more temporary reference signals (T-RSs) which are user equipment (UE) specific reference signals. The UE can use the T-RSs for fine time/frequency (T/F) tracking and Automatic Gain Control (AGC) adjustment of corresponding SCells resulting in reduced SCell activation latency compared to utilizing a Synchronization Signal (SS)/Physical Broadcast Channel (PBCH) Block Measurement Timing Configuration (SMTC).

Simultaneous multiple secondary cell (SCell) fast activation

A wireless network may include a base station and user equipment (UE). The UE may transmit uplink (UL) signals to the base station using a dynamically adjustable maximum UL duty cycle. When the UE identifies that a user is in proximity to the UE, the UE may transmit an indicator to the base station. The indicator may identify that a radio-frequency exposure (RFE) event has occurred and/or a suggested maximum UL duty cycle that would allow the UE to satisfy limits on RFE. The base station may limit a UL grant to the UE so that the UE performs subsequent communications using the suggested maximum UL duty cycle or a different maximum UL duty cycle. Coordinating adjustment of UL duty cycle in this way may allow the UE to meet limits on RFE without requiring the UE to perform maximum transmit power level reductions.

Systems and methods for controlling uplink duty cycle

The present application relates to devices and components including apparatus, systems, and methods for configuring an uplink gap for a 5G NR user equipment.

Systems and methods for uplink gap configuration for transceiver calibration and transmit power management

The present application relates to devices and components including apparatus, systems, and methods to provide uplink spatial relation switch delay for an uplink spatial relation switch based at least in part on a pathloss reference signal associated with uplink spatial relation switch.

Uplink spatial relation switch delay

A cellular base station (BS) which determines an aperiodic sounding reference signal (SRS) triggering offset configuration specifying an offset between an aperiodic SRS trigger received by a user equipment (UE) and transmission of the SRS by the UE. The cellular base station may determine that the SRS triggering offset should be adjusted. In response, the cellular base station may transmit signaling to the UE specifying a new value for the aperiodic SRS triggering offset. The new SRS triggering offset value may be partly based on a minimum timing offset for the UE and may be contained in a medium access control (MAC) control element (CE) or in downlink control information (DCI). Additionally, the new triggering offset value may be applicable for a plurality of component carriers or bandwidth parts. The cellular base station may also determine a new triggering offset value due to conflicts regarding the AP-SRS transmission.

Dynamic configuration of aperiodic sounding reference signal offsets in cellular communications systems

Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for support mobility in a wireless network for user equipments (UEs) with varying capabilities. A UE can receive a first system information from a serving base station, where the first system information includes a UE capability condition associated with a neighbor base station, and determine whether a UE capability meets the UE capability condition associated with the neighbor base station. When the UE capability condition is met, the UE can determine whether a first measurement of a first reference signal received from the serving base station and a second measurement of a second reference signal received from the neighbor base station satisfy a threshold condition. When the threshold condition is met, the UE can obtain a second system information from the neighbor base station, indicating the UE has performed handover to the neighbor base station.

Mobility support for user equipments with varying capabilities in a wireless network

Techniques discussed herein can facilitate the use of reference signals in active TCI switching. One example aspect is a user equipment (UE), comprising: a memory interface; and processing circuitry communicatively coupled to the memory interface and configured to: receive a physical downlink shared channel (PDSCH) message that includes an activation command indicating a target transmission configuration indicator (TCI) state; decode the activation command within a decoding period, where the decoding period is a time period allocated for the UE to decode the activation command; receive a TCI resource where the TCI resource is a reference signal; perform time and frequency tracking associated with the target TCI state according the TCI resource; and switch to the target TCI state after performing time and frequency tracking.

Reference signals in active TCI switching

This disclosure relates to techniques for aligning wireless device and cellular network expectations and behavior in conjunction with neighbor cell measurements in a wireless communication system. A wireless device may determine that a reference signal is configured for a neighbor cell measurement when communication with the serving cell is also configured. The wireless device may determine whether the reference signal for the neighbor cell measurement is configured with same or different subcarrier spacing as the communication with the serving cell. The wireless device may select one or more of the reference signal for the neighbor cell measurement or the communication with the serving cell to receive based at least in part on whether the reference signal for the neighbor cell measurement is configured with same or different subcarrier spacing as the communication with the serving cell.

Wireless device scheduling availability during neighbor cell measurements

Embodiments of the present disclosure describe methods, apparatuses, storage media, and systems for configuring and implementing radio resource management (RRM) measurements for monitoring neighboring cells based on synchronization signal block (SSB) timing groups in an radio resource control (RRC) connected (RRC_CONNECTED) state. Various embodiments describe how to determine a set of SSB timing groups, and how to generate a receiver switching pattern based on the set of SSB timing groups and or SSB scanning measurements. The embodiments also describe determination and implementation of an SSB scanning mode and an SSB Other embodiments may be described and claimed.

Dynamic radio frequency switching in new radio for radio resource management in radio resource control connected state

A user equipment (UE) is configured to receive a measurement configuration from a serving cell, wherein the measurement configuration comprises event configuration associated with radio resource management (RRM) relaxation, perform measurements of the serving cell, transmit a measurement report to the serving cell and receive an indication from the serving cell that RRM relaxation for radio resource control (RRC) connected mode is enabled at the UE.

Radio resource management relaxation for radio resource control connected mode

This disclosure describes methods, systems, and devices for handover of a user equipment (UE) from a source node of a radio access network (RAN) to a target node of the RAN. In one example, a method involves receiving, by the UE and from the source node, a RACH-498 handover message comprising: (i) an uplink grant for establishing a connection with the target node, and (ii) an identifier of a reference signal associated with a beam of the target node. The method also involves performing, by the UE, a handover based on the RACH-less handover message.

Enhanced RACH-less handover

Techniques discussed herein can facilitate enhanced radio resource management measurements for wireless technology including New Radio (NR). One example aspect is a baseband processor of a user equipment (UE), including one or more processors configured to receive a measurement link information state link information. The one or more processors are further configured to determine, from the measurement link information, a number of synchronization signal block based measurement timing configurations (SMTCs) (Y) per Rx beam of a number of receive (Rx) beams (N); generate at least one of a subset number of Rx beams (N) of the number of Rx beams based on the measurement link information, or an increased number of SMTCs (Y) of the number of SMTCs corresponding to the number of Rx beams; and perform radio resource management (RRM) measurements according to one or more of the subset number of Rx beams or the increased number of SMTCs.

Enhanced radio resource management measurements

A base station communicates with a first user equipment (UE) and a second UE. The base station determines a first configuration for the first UE for a channel state information reference signal (CSI-RS) on a symbol, schedules a data transmission for the second UE on the symbol where the CSI-RS is configured so that the CSI-RS and the data transmission collide on the symbol and determines a second configuration for the first UE when the CSI-RS and the data transmission collide on the symbol.
