Abstract: Example embodiments of the present disclosure relate to channel information transmitting for dormant bandwidth part. According to embodiments, a solution for channel information transmitting for dormant bandwidth part has been proposed. A terminal device is configured a periodicity when an active downlink (DL) bandwidth part (BWP) is a dormant BWP. The periodicity is different from a further periodicity which is configured and used when the active DL BWP is a non-dormant BWP. The terminal device uses resourced configured for the active uplink (UL) BWP but with the different periodicity. In this way, it allows sounding reference signal (SRS)/channel state information (CSI) reporting without duplicating configurations of BWPs. It can configure a required longer periodicity but reduce the SRS configuration for each UL BWP.

Abstract: Improved techniques of intra and inter distributed unit mobility include determining, by a user equipment served by a source cell, whether a target cell belongs to the same distributed unit as the source cell based on information sent by the central unit (control plane) after a connection with the network node has been established. The information sent by the network node includes, for each cell, a group identifier identifying the distributed unit with which that cell is associated. When measurement data provided by the user equipment indicates readiness for a serving cell change to a target cell, the user equipment uses the group identifier to determine whether the target cell belongs to the same distributed unit as the source cell (intra-distributed unit mobility scenario) or a different distributed unit as the source cell (inter-distributed unit mobility scenario).

Abstract: Techniques of wireless communications include enabling the UE to indicate region in the channel bandwidth of a band combination where the MSD is zero or small. The indication defines a frequency boundary where MSD is “low” (e.g., small or zero dB) and MSD is “high” (e.g., >0 dB), and may contain a frequency offset from the centre of the MSD originating source to the boundary. The UE indication may be given as part of UE capabilities (e.g., UE indicates per BC the MSD region and MSD value within the region), or as a part of UE response to a network request (e.g., network requests UE to report MSD values for a given band combination and UE provides the information), with a UE capability for supporting such request-response mechanism.

Abstract: A technique of performing a HO includes the source BS sending a HO resume message to the UE at the conclusion of a RACH access procedure that occurs in response to a HO command while a second TRX of the UE continues to exchange data packets with the source BS as if no HO command were issued. By continuing to exchange data with the source BS as if there were no HO command until the HO resume message reintroduces a RACH-less HO procedure, the interruption may be reduced to about 4 msec. At any point in time the UE handles only one protocol stack and only one security, which avoids the complexity of the advanced prior art methods.
