Various solutions for physical downlink control channel (PDCCH) monitoring enhancement for carrier aggregation (CA) with respect to user equipment and network apparatus in mobile communications are described. An apparatus may transmit a capability report to indicate a supported PDCCH monitoring capability to a network node. The apparatus may receive a PDCCH monitoring configuration compliant with the supported PDCCH monitoring capability from the network node. The apparatus may determine a monitoring budget based on the PDCCH monitoring configuration and the supported PDCCH monitoring capability. The apparatus may perform a PDCCH monitoring according to the monitoring budget.

The invention refers to a method at a user equipment for performing a random access procedure, wherein the UE randomly selects a random access preamble from a given set of preambles to be used for the random access procedure, the method comprising the steps of detecting (420) a partitioning of the given set of random access preambles into a first and a second partition, detecting (430) a certain capability of the UE, and selecting (440) a random access preamble from the fist partition to indicate the certain capability to a base station; the invention further refers to a corresponding method in a base station, a corresponding UE, and a corresponding base station.

Systems, apparatuses, and methods are described for wireless communications. A base station and wireless device may communicate capability information associated with a wireless device. The capability information may include information indicating support for an Ethernet type packet data unit session or header parameter compression. An Ethernet type packet data unit session may be instantiated based on the capability information.

Improved techniques of managing measurement gaps for MPUEs include identifying an idle time for the UE in a coordinated and network-controlled manner during which the UE is able to perform SSB/CSI-RS based measurements for a serving cell using non-serving panels. Such idle time is defined as an omitted operation time (i.e., an idle time of a certain pre-defined length) in which the network has to apply the scheduling restrictions in the SSBs' symbols to the UE. Note that currently as per the RAN4 requirements, the network must apply scheduling restrictions in all SSB symbols for all UEs in FR2 at any time (i.e., worst case scenario).

A user equipment that is provided in a wireless communication system including a base station and the user equipment includes an acquisition unit that acquires information indicating a resource position where a downlink data channel is mapped or a resource position where an uplink data channel is mapped in a radio frame and a timing when an HARQ response to downlink data is transmitted from the user equipment or a timing when an HARQ response to uplink data is received from the base station and a communication unit that transmits an HARQ response to downlink data received by the downlink data channel at a timing when the HARQ response to the downlink data is transmitted and receives an HARQ response to data transmitted by the uplink data channel or retransmission data scheduling information at a timing when the HARQ response to the uplink data is received.

Aspects relate to mechanisms for a wireless communication device to configure and indicate one or more beams for sidelink communication with another wireless communication device. The sidelink communication can include first stage sidelink control information (SCI) and second stage SCI that may be communicated on a first beam configured on the wireless communication devices. The sidelink communication can further include sidelink data traffic that may be communication on a second beam. The second beam may be the first beam or a different beam based on at least one of a beam capability of at least the first wireless communication device or a gap between the sidelink data traffic and at least one of the first stage SCI or the second stage SCI.
