Abstract: Embodiments of a User Equipment (UE), Generation Node-B (gNB) and methods of communication are disclosed herein. The UE may attempt to decode sidelink synchronization signals (SLSSs) received on component carriers (CCs) of a carrier aggregation. In one configuration, synchronization resources for SLSS transmissions may be aligned across the CCs at subframe boundaries in time, restricted to a portion of the CCs, and restricted to a same sub-frame. The UE may, for multiple CCs, determine a priority level for the CC based on indicators in the SLSSs received on the CC. The UE may select, from the CCs on which one or more SLSSs are decoded, the CC for which the determined priority level is highest. The UE may determine a reference timing for sidelink communication based on the one or more SLSSs received on the selected CC.

Abstract: Systems and methods configured to provide size matching of downlink control information (DCI) formats to restrict a number of DCI format sizes for a set of DCI formats for concurrent use are described. In accordance with embodiments of the present disclosure, size matching at least two DCI formats of a set of DCI formats to restrict a number of DCI format sizes for the set of DCI formats for concurrent use is implemented. Restrictions with respect to the number of DCI format sizes for the set of DCI formats may correspond both to a first number of DCI sizes parameter based on a total number of DCI format sizes per wireless communication slot, and to a second number of DCI sizes parameter based on a total number of DCI format sizes for DCI formats used to carry DCI payload encoded using an identifier per wireless communication slot.

Abstract: Certain aspects of the present disclosure provide techniques for quasi-colocation (QCL) assumption for an aperiodic channel state information (A-CSI) reference signal (RS) configured with multiple transmission reception point (mTRP). A user equipment (UE) may receive signaling configuring the UE with a plurality of index values associated with different control resource sets (CORESETS). The UE may receive, from a base station (BS), first downlink control information (DCI) triggering an A-CSI-RS resource set for A-CSI reporting. The first DCI is received in a first CORESET of the different CORESETs associated with a first index value of the plurality of index values. The UE may determine a first time offset between the first DCI and the A-CSI-RS resource set. When the first time offset is smaller than a threshold time offset, the UE may determine a QCL assumption for receiving the A-CSI-RS based, at least in part, on the first index value.

Abstract: The present invention introduces a system, which comprises a telecommunication network structure, which can be called as an intelligent combination of Push-To-Talk (i.e. Direct Mode Operation, DMO) communication technique and cellular network application. The DMO can be set as a preferred choice if it is available. The subscriber devices retransmit (i.e. forward) the data message further until the message reaches the called subscriber terminal. The total cumulative hop between subscriber terminals may comprise both DMO-based hops and cellular connections. ID means are provided, and telemetric information can be sent from the terminals. The invention allows emergency information submissions from the terminals, and forced broadcast information from an administrator to the terminals as well. Dynamic Talk Groups (DTG) can be defined based on geographic locations on each registered user.

More specifically, the present invention relates to a method and a device for reporting CSI in a wireless communication system, the method comprising: a step for configuring a plurality of serving cells; and a step for reporting the CSI of only one serving cell in a corresponding subframe, wherein the step for reporting the CSI of only one serving cell comprises: excluding reporting the CSI of a lower priority when CSI reports of the plurality of serving cells in the corresponding subframe collide; and excluding reporting the CSI of serving cells other than the serving cell having the smallest index when the CSI reports of different serving cells having the same priority in the corresponding subframe collide.

Abstract: Handling of UE capability information in a mobile telecommunications network wherein an eNodeB receives information regarding the UE capability information from the UE and stores the information. The eNodeB sends the UE capability information to the EPC, i.e., to an MME, which receives and stores the UE capability information. When the UE transits from idle to active state, does an initial attach, or when a part of the UE capabilities have changed, it sends a message to the eNodeB regarding the update. The eNodeB forwards the message to the MME, which sends a response associated with the previously stored UE capability information to the eNodeB. The eNodeB decides whether the UE capabilities stored in the MME is up-to-date based on the message from the UE and the response from the MME. If the UE holds updated UE capabilities the eNodeB can request updated UE capability information from the UE.

Abstract: This application provides a data processing method and apparatus, and a computer storage medium. When a PDCP entity over a UM DRB is re-established, or when a cell handover occurs and the PDCP entity over a UM DRB uses a key used before the handover, the PDCP entity determines a first SDU, where the first SDU is an SDU that is associated with a sequence number by the PDCP entity but whose corresponding data has not been transmitted through an air interface; and delivers a PDU corresponding to the first SDU to an RLC entity. Data corresponding to the first SDU is redelivered, to avoid a data packet loss caused by preprocessing of the PDCP entity.

Abstract: In one embodiment, an offload platform is an compute platform, adjunct to a router or other packet switching device, that performs packet processing operations including determining an egress forwarding value corresponding to the next-hop node of the packet switching device to which to send an offload-platform processed packet. The offload platform downloads forwarding information from the router, and augments it, such as, but not limited to, representing interfaces of the router as identifiable virtual interface(s) on the offload platform, and including each of one or more next-hop nodes of the router represented as an identifiable virtual adjacency and identifiable tunnel (e.g., identified by the egress forwarding value). In one embodiment, the egress forwarding value is an Multiprotocol Label Switching (MPLS) label or Segment Routing Identifier. The router identifies packets of certain packet flows to send to the adjunct offload platform, rather than processing per its routing information base.

Each RAT has a flexible subcarrier spacing and symbol duration, which are integer multiples of a base subcarrier spacing and symbol duration, and is associated with at least one of different temporal and frequency resources. The symbol and/or frame structure of each RAT are independent. A Transmission Time Interval (TTI) boundary between the RATs is common, and the RATs comprise a common reference TTI duration. The information of the RATs is provided either via a different RAT than the RAT used by the UE for communication or via a dedicated carrier in the RAT used by the UE for communication.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) to provide hybrid automatic repeat request (HARQ) feedback for multiple physical channels (e.g., multiple physical downlink shared channels (PDSCH)) scheduled via cross component carrier. The UE may monitor control channel occasions, to receive wireless communications from a base station. For example, the UE may receive downlink control information (DCI) messages that may schedule multiple PDSCH over different component carriers. The DCI messages may include an indication of a timing offset for HARQ feedback for the multiple PDSCH. In some examples, the UE may be configured to receive multiple DCI messages and order the DCI messages based on component carrier indices or a PDCCH occasion, or both. The UE may then determine a slot to transmit HARQ feedback for the multiple PDSCH based on an indication in a latest DCI message identified according to the ordering.

Abstract: A method and apparatus provides for receiving an indication of an uplink resource allocation of resource blocks for a transmission on a master cell group. An indication is received of an uplink resource allocation of resource blocks for a transmission on a secondary cell group. A total additional maximum power reduction is determined based on the indication of the uplink resource allocation of the resource blocks for the transmission on the master cell group and the indication of the uplink resource allocation of the resource blocks for the transmission on the secondary cell group. A remaining power is determined for the secondary cell group by reducing a signaled maximum dual-carrier power by the total additional maximum power reduction and subtracting a configured master cell group power. A secondary cell group additional maximum power reduction is determined as the difference between a signaled maximum secondary cell group power and the remaining power for the secondary cell group.
