Abstract: A dynamic spectrum management (DSM) engine may determine the channel quality of one or more channels associated with the DSM engine when packets are not being transmitted over the channels. For example, the DSM engine may trigger a channel quality measurement on a non-primary channel on a condition that a predetermined period of time has lapsed since the last activity associated with the non-primary channel. Channel quality measurement may be triggered via a data sending event on the non-primary channel such as sending a data frame on the non-primary channel. The DSM engine may perform respective quality measurements on multiple channels and store the respective quality values in a database. Time-averaged channel qualities for the channels may be computed based on the stored quality values for computing transmit power distribution of across the channels.

Abstract translation: 动态频谱管理（DSM）引擎可以在不通过信道发送分组时确定与DSM引擎相关联的一个或多个信道的信道质量。 例如，DSM引擎可以在从与非主信道相关联的最后活动经过预定时间段的情况下在非主信道上触发信道质量测量。 信道质量测量可以通过非主信道上的数据发送事件来触发，例如在非主信道上发送数据帧。 DSM引擎可以对多个通道执行相应的质量测量，并将相应的质量值存储在数据库中。 可以基于用于计算跨信道的发射功率分布的存储的质量值来计算信道的时间平均信道质量。

Abstract: Methods and devices are disclosed to configure a wireless transmit receive unit (WTRU) with multiple physical downlink control channel (PDCCH) control resource sets (CORESETs) including at least a first PDCCH CORESET identifying first frequency resources of a downlink (DL) bandwidth part (BWP) for detection of downlink control information (DCI) and a second PDCCH CORESET identifying second frequency resources of the DL BWP for detection of DCI. The WTRU monitors one or more search spaces linked to active PDCCH CORSETs for transmissions of DCI. On determination that an interferer may impact PDCCH resources, a network sends, and a WTRU receives, signaling to suspend monitoring of search spaces linked to one of the first PDCCH CORSET or the second PDCCH CORESET for a suspend time period. Upon expiration of the suspend time period or sending/receiving unsuspend signaling, the WTRU resumes monitoring search spaces linked to a previously suspended PDCCH CORESET.

Abstract: A wireless transmit receive unit (WTRU) and methods are disclosed for mitigating radar interference with uplink control channels may include receiving configuration information including a set of dedicated physical uplink control channel (PUCCH) resources for scheduling requests (SRs), the set includes first PUCCH resources of an UL BWP, and second PUCCH resources of the UL BWP different from the first PUCCH resources. SRs are sent using the first PUCCH resources while the second PUCCH resources are suspended from use. The WTRU receives signaling from a network to suspend one or more of the first PUCCH resources, and unsuspend one or more of the second PUCCH resources. Thereafter, subsequent SRs are sent using only unsuspended PUCCH resources of the UL BWP and not the suspended PUCCH resources, in response to the received signaling from the network. Additional embodiment are disclosed.

Abstract: Examples for ensuring robust SRS transmission and reception can occur when coexisting with interference include moving WTRU SRS transmissions out of the interference band to mitigate interference to and from the interferer, increasing the number of OFDM symbols and/or the repetition factor for SRS to overcome the interference, dynamic switching/suspending of semi-persistent SRS and/or aperiodic SRS to mitigate interference to and from the interferer, and power boosting of SRS transmissions to overcome the interference.

Abstract: The system and method detect at least one cell defining SSB (CD-SSB), extract information associated with at least one other CD-SSB, the information including at least the absoluteFrequencyotherSSBs for the at least one other CD-SSB, extract an absoluteFrequencySSB from a network, determine if absoluteFequencySSB is in a list of absoluteFrequencyotherSSBs and if so, the CD-SSB indicated by the absoluteFrequencySSB, read the SIB1 associated with the CD-SSB indicated by the absoluteFrequencySSB and perform random access using RACH resources corresponding to the read SIB1. The system and method may further include if the absoluteFrequencySSB is determined to not be in the list of absoluteFrequencyotherSSBs, read at least one SIB1 associated with at least one other CD-SSB indicated by an absoluteFrequencyotherSSB in the list of absoluteFrequencyotherSSBs and perform random access using RACH resources corresponding to the read at least one SIB1.
