Aspects of the disclosure provide an electronic device including processing circuitry and a method for beam failure recovery. The processing circuitry can determine whether beam failure occurs on at least one of a plurality of cells configured for serving an electronic device. When the beam failure is determined to occur on the at least one of the plurality of cells, the processing circuitry can send an uplink message that includes a first portion and a second portion to a network. The first portion indicating the beam failure is transmitted using a physical random access channel (PRACH) resource. The second portion indicates at least one of cell information of the at least one of the plurality of cells and new beam information of one or more new candidate beams for the at least one of the plurality of cells and is transmitted using a physical uplink shared channel (PUSCH) resource.

Aspects of the disclosure relate to minimizing the block error rate (BLER) experienced by a user equipment (UE) upon a downlink beam switch at the base station. The base station may mitigate the link adaptation convergence transient upon performing a beam switch by modifying the modulation and coding scheme (MCS) according to a difference in reference signal received power (RSRP) between the old beam and the new beam. The base station may further adjust the MCS utilizing an outer-loop link adaptation process or channel state feedback (CSF) provided by the UE after the beam switch. Other aspects, features, and embodiments are also claimed and described.

In embodiments, a base station may send to a user equipment (UE) a P3 beam management (BM) channel state information reference signal (CSI-RS) having two ports, and may receive from the UE a P3 BM report in response. The P3 BM report may include a proactive UE beam switch indication and a CSF report corresponding to the best UE beam determined by a UE based on the P3 BM CSI-RS. The base station may determine whether the P3 BM report includes an indication that the UE will perform a beam switch from a first UE beam to a second UE beam, and may determine a UE beam switch slot during which the UE will perform the beam switch. Starting at the beam switch slot, the base station may send a physical downlink shared data channel (PDSCH) transmission to the UE using the adjusted downlink transmission parameters.

A communication device for handling a physical downlink (DL) control channel (PDCCH) reception comprises at least one storage device; and at least one processing circuit, coupled to the at least one storage device. The at least one storage device stores instructions, and the at least one processing circuit is configured to execute the instructions of changing from a first active bandwidth part (BWP) of a serving cell of a network to a second active BWP of the serving cell according to at least one first indicator; and determining whether to detect a PDCCH according to at least one search space (SS) set for the serving cell, after changing to the second active BWP.

Systems and methods provide inter-band EN-DC coverage combinations to wireless devices in a cell wherein each inter-band coverage has corresponding handover criteria. The method includes determining a power class for at least one wireless device, wherein the power class is one of a high-power class and a low power class. The method additionally includes comparing the handover criteria of at least two inter-band coverage combinations to identify relaxed handover criteria and assigning the high-power class wireless device to an inter-band coverage combination having the relaxed handover criteria.

A computer-implemented method may include providing, to a cell, a selection of a number of neighboring tiers for selection by the cell. The method also provides a database storing in a first list: frequencies broadcasted from the cell, neighboring co-site cells of the cell, and neighboring cells surrounding the cell for a selected number of tiers. The method provides a database storing defined frequency relations for the cell and frequencies corresponding to the defined frequency relations to provide a second list of frequencies. The second list includes frequencies available for handover to a user equipment in the cell. The method determines if the second list is missing any of the frequencies of the first list. If the determining is positive, the method processes a request to add frequency relations corresponding to the missing frequencies to the defined frequency relations of the cell.

Various examples pertaining to enhancements for faster bandwidth part (BWP) switching in mobile communications are described. An apparatus, implementable in a user equipment (UE), receives a trigger from a network node. In response to receiving the trigger, the UE performs BWP switching with a restriction on software (SW) or radio frequency (RF) reconfiguration such that the BWP switching is faster with the restriction than without the restriction. The UE then performs a transmission to the network node after the BWP switching.
