Abstract: An approach is described for a user equipment (UE) to receive a channel state information (CSI) reporting configuration message from a source device of a first cell and receive a channel state information reference signal (CSI-RS) from a second cell via the source device. The UE determines a first number of CSI-RS resources of a first time slot duration corresponding to the first cell, a second number of CSI-RS resources of a second time slot duration corresponding to the second cell, an overall time slot duration based on the first and the second time slot duration, an overall number of CSI-RS resources of the overall time slot duration based at least on the first and the second number of CSI-RS resource, generates a capability report at least based on the overall number of CSI-RS resource, and transmits the capability report to the source device.

Abstract: A method for wireless communication includes: requesting transmission, by a wireless device, of uplink (UL) transmissions to a wireless station; receiving, by the wireless device, a UL cancellation indication (CI) to be applied to a determined reference region; determining, by the wireless device, a set of UL resources for cancellation based on the UL CI received from the wireless station (e.g., by determining an indication of particular interlaces and/or particular Physical Resource Blocks within such interlaces that are to be canceled), wherein at least a subset of the UL resources for cancellation are interlaced; and canceling, by the wireless device, UL transmissions over at least the determined set of UL resources for cancellation (i.e., additional UL transmissions may be cancelled, too). The wireless device may then perform UL transmissions that do not overlap with the determined set of UL resources for cancellation in any UL CI to the wireless station.

Abstract: Switching schemes at a mobile device may include, in response to being within range of a transmission and reception point (TRP) of a plurality of TRPs associated with a high speed train (HST), decoding a communication received from a network. The communication may include a first radio resource control (RRC) information element (IE) having an HST configuration associated with an HST scheme. The HST configuration may be applied to thereby operate using the HST scheme. In response to being out of range of the plurality of TRPs associated with the HST, a communication received from the network may be decoded. The communication may include a second RRC IE having a non-HST configuration associated with a non-HST scheme. The non-HST configuration may be applied to thereby operate using the non-HST scheme.

Abstract: A base station of a network provides a user equipment (UE) with information relating to monitoring a Physical Downlink Control Channel (PDCCH) of multiple component carrier (CCs) in a carrier aggregation (CA) scheme. The base station configures a first CC and a second CC of a CA combination for a user equipment (UE) and provides the UE with information for the CA combination, wherein the information comprises an indication whether the first CC and the second CC are collocated.

Abstract: A user equipment (UE), or other network component can operate to configure different sets of resources for an uplink (UL) physical channel for an uplink (UL)-to-downlink (DL) channel occupancy time (COT) sharing to coexist with another radio access technology (RAT). An energy detection (ED) threshold can be selected from the different sets of resource configurations for an UL transmission based on one or more conditions. A gap can be configured between a physical random access control channel (PRACH) transmission and a PUSCH transmission based on one of at least a first value associated with a numerology between the PRACH and the PUSCH and a second value greater than the first value. The UL transmission can be provided based on the ED threshold or the configured conditional gap via the UL physical channel.
