Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH) during a random access channel (PRACH) procedure. The UE receives a physical random access channel (PRACH) resource on a first sub-band of a component carrier (CC), wherein the CC is divided into a plurality of sub-bands and receives a Type1-PDCCH CSS (Physical Downlink Control Channel Common Search Space) set on a second sub-band of the CC, wherein the Type1-PDCCH CSS set corresponds to the PRACH resource.

Abstract: Techniques of beamforming in reference signal (RS) transmissions, applicable to frequency ranges including frequencies between 52.6 GHz and 71 GHz, are described. Such techniques may include determining a communication channel is unoccupied for an initial duration, determining a number of communication slots of the communication channel to defer for transmission, and counting one or more communication slots of the communication channel that are not in use. The techniques may include determining the number of counted one or more communication slots is not equal to the determined number of communication slots of the communication channel to defer, and transmitting one or more data units based on the determination that the number of the counted one or more communication slots is not equal to the determined number of communication slots of the communication channel to defer.

Abstract: A user equipment (UE) is configured to handle physical downlink shared channel (PDSCH) transmissions during multi-transmission/reception point (TRP) operation. The UE receives a physical downlink control channel (PDCCH) transmission configured with downlink control information (DCI) in a single-DCI, multi-transmission/reception point (TRP) operation, wherein the DCI schedules reception of a physical downlink shared channel (PDSCH) transmission, determines whether or not a TCI field is configured in the DCI, when the TCI field is not configured in the DCI, determining a default beam based on a control resource set (CORESET) with the lowest ID in the PDCCH and when the TCI field is configured in the DCI, determining whether the TCI field indicates a TCI codepoint includes two TCI states.

Abstract: A user equipment (UE) reports channel state information for multiple transmission reception points (TRPs) to a network. The UE collects channel state information (CSI) corresponding to multiple transmission reception points (TRPs), receives a signal configured to trigger a semi-persistent CSI (SP-CSI) report from a first TRP of the multiple TRPs, generates a SP-CSI report that includes CSI corresponding to each TRP of the multiple TRPs and transmits the SP-CSI report to a cell associated with the multiple TRPs.

Abstract: This disclosure describes the following enhancement to improve the PDCCH reliability: PDCCH aggregation and multi-beam PDCCH reception for a 5G wireless communication system. The disclosed techniques entail obtaining repeated PDCCH by processing a PDCCH-Config, ControlResourceSet, or SearchSpace configuration parameter including an information element (IE) indicating a number of consecutive slots in which the PDCCH is repeated. In another embodiment, a gNB generates the PDCCH-Config, ControlResourceSet, or SearchSpace configuration parameter for configuring a UE to receive the repeated PDCCH and employ the multi-beam PDCCH reception.

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 network may authenticate a user equipment (UE) to access an edge data network. The network generates a first credential based on a second credential, the second credential generated for a procedure between the UE and a cellular network corresponding to the network component, receives an identifier associated with the first credential from a further network component in response to the UE transmitting an application registration request to a server associated with an edge data network and retrieves the first credential based on the identifier. The network also receives a multi-access edge computing (MEC) authorization parameter, verifies the MEC authorization parameter and transmits an authentication verification response to a second network component.

Abstract: The exemplary embodiments relate to signaling between a user equipment (UE) and a cell over the unlicensed spectrum. The UE may receive a signal broadcast by a cell of the network over a channel in the unlicensed spectrum. The signal includes a set of channel state information reference signals (CSI-RS) each corresponding to a set of synchronization signal blocks (SSB) and is transmitted during a discovery reference signal (DRS) window. The UE may then determine a location of the set of CSI-RS within the DRS window and perform an operation based on the set of CSI-RS.

Abstract: A user equipment (UE) and a network agree on the use of a hybrid automatic repeat request (HARQ) codebook. The UE receives a plurality of downlink control information (DCI) transmissions during a corresponding plurality of physical downlink control channel (PDCCH) monitoring occasions from the base station, wherein each DCI transmission schedules multiple physical downlink shared channel (PDSCH) transmissions on a corresponding one of a plurality of component carriers (CCs), receives a time domain resource allocation (TDRA) table configuration from the base station, determines a maximum number of PDSCH transmissions per CC based on the TDRA table configuration, groups the plurality of CCs together and determines a hybrid automatic repeat request (HARQ)-acknowledgement (ACK) codebook size based on a number of the multiple PDSCH transmissions, the maximum number of PDSCH transmissions, and a resulting ACK or negative acknowledgement (NACK) for each of the multiple PDSCH transmissions.
