    Abstract: Techniques for performing inter-frequency and/or inter-radio access technology (RAT) measurements are disclosed. A multi-receiver wireless transmit/receive unit (WTRU) may receive downlink transmissions via a plurality of downlink carriers, of a set of configured downlink carriers, simultaneously. The WTRU may receive gap configuration information for at least one of the set of configured downlink carriers. The WTRU may further perform inter-frequency measurements on carriers outside of the set of configured downlink carriers during a measurement gap in response to the received gap configuration information. The WTRU may further receive information that at least one of the set of configured downlink carriers is to be disabled. The WTRU may then perform measurements on the frequency of the disabled downlink carrier without using measurement gaps. The WTRU may perform measurements on the disabled carrier without measurement gaps maintaining a status of the disabled carrier as disabled at a physical layer.

    Abstract translation: 公开了用于执行频率间和/或无线电间接入技术（RAT）测量的技术。 多接收机无线发射/接收单元（WTRU）可以同时经由一组配置的下行链路载波经由多个下行链路载波接收下行链路传输。 WTRU可以为所配置的下行链路载波的集合中的至少一个接收间隙配置信息。 响应于接收到的间隙配置信息，WTRU可以在测量间隙期间进一步对配置的下行链路载波集合之外的载波执行频率间测量。 WTRU可以进一步接收要被禁用的所配置的下行链路载波中的至少一个的信息。 然后，WTRU可以在不使用测量间隙的情况下对禁用的下行链路载波的频率执行测量。 WTRU可以在禁用的载波上执行测量，而没有将物理层上的禁用的载波的状态保持为禁用的测量间隙。

    Abstract: A WTRU may receive downlink control information (DCI) from a first transmission/reception (TRP). The DCI may indicate that the WTRU is to transmit a physical random access channel (PRACH) transmission. The DCI may include an indication of a preamble, an indication of a first PRACH mask, and/or an indication associated with a first synchronization signal block (SSB), and/or an indication of a reference signal (RS). The WTRU may be configured to transmit the preamble, to a second TRP, the preamble in a first PRACH resource. The first TRP and/or the second TRP may be associated with a same physical cell identity (PCI). The WTRU may receive, from the second TRP, a first response to the preamble. The first response may include a first timing advance (TA) command for the second timing alignment for transmission to the second TRP and/or an index indicating the second TRP.

    Abstract: Systems, methods, and instrumentalities are disclosed herein associated with transmission of demodulation reference signals (DMRS) in wireless systems. DMRS symbols may be placed in a slot for channel estimation operations. For example, channel estimation performance may be enhanced based on using an increased number of DMRS symbols. Channel estimation enhancements may be performed by transmitting DMRS symbols in an extended slot, for example, to avoid data degradation (e.g., which may result from replacing data transmission symbols with DMRS symbols). An extended slot may be a slot that includes symbols spanning across multiple slots (e.g., two slots, consecutive slots), for example, such as a slot n and a slot n+1.

    Abstract: Methods, apparatuses, systems, etc. directed to beam management for, and/or for use in connection with, multiple cells and/or multiple transmission/reception points are provided. Among the methods is a method that may include any of determining first and second reference signals sets (RS sets) associated with first and second sets of beams; receiving information for first and second beam failure recovery (BFR) sets corresponding to the first and second RS sets, wherein the information indicates an RS set associated with candidate beams (CB-RS set) and an uplink resource set for each of the first and second BFR sets; determining beam failures based on the first and second RS sets; selecting the CB-RS set and UL resource set from the first or second BFR set; determining an RS of the selected CB-RS set; and transmitting information indicating the beam failures using uplink resources of the selected uplink resource set.
