Abstract: A partial sounding method for sounding-reference-signal (SRS) is proposed. The network node may transmit higher-layer signal configuring a fractional SRS resource for partial sounding in configured resource blocks (RBs) to user equipment (UE). The UE may determine an SRS sequence length and a frequency-domain starting position of the fractional SRS resource based on the higher-layer signal to increase the SRS capacity.

Abstract: A method for providing multiple physical uplink control channel (PUCCH) resources for a uplink control information (UCI) report can include receiving one or more PUCCH resource configurations from a base station (BS) at a user equipment (UE) in a wireless communication system, and determining a first PUCCH resource configuration from the one or more PUCCH resource configurations for reporting a UCI. The first PUCCH resource configuration can indicate multiple frequency domain transmission occasions in a bandwidth. The UCI can be transmitted on at least one of the multiple frequency domain transmission occasions indicated by the first PUCCH resource configuration.

Abstract: Apparatus and method for beam failure recovery (BFR) are proposed. The network node may allocate channel state information-reference signal (CSI) configuration for the user equipment (UE). The CSI configuration may comprise at least one CSI-reference signal (CSI-RS) associated with a serving transmission configuration indication (TCI) for the UE. In addition, the network node may transmit the CSI configuration to the UE. The UE may perform BFD procedure to determine whether a beam failure happens and transmit a beam failure recovery (BFR) request to the network node when the beam failure happens. In addition, the UE may perform operations based on the CSI-RS associated with the serving TCI when the UE receives a response from the network node for the BFR request.

Abstract: A user equipment terminal (UE) operates in a wireless network according to a configuration. The UE receives the configuration for a physical downlink control channel (PDCCH), and detects downlink control information (DCI) in the PDCCH. From the DCI, the UE receives control information for a serving cell configured with one or more bandwidth units in a frequency domain. The control information is provided for each bandwidth unit of the serving cell. According to the control information, the UE performs a downlink reception from the serving cell or an uplink transmission to the serving cell.

Abstract: Aspects of the disclosure provide a user equipment (UE). The UE receives configuration information of multiple transmission configuration indication (TCI) states. The UE receives one or more activation commands that associate a first subset of the TCI states with one or more codepoints of a TCI field and a second subset of the TCI states with the one or more codepoints of the TCI field. The UE receives a codepoint associated with a first TCI state in the first subset of the TCI states and a second TCI state in the second subset of the TCI states. The UE determines at least one first quasi co-located (QCL) assumption according to the first TCI state and at least one second QCL assumption according to the second TCI state. The UE receives a downlink transmission based on the at least one first QCL assumption and the at least one second QCL assumption.

Abstract: A method of default uplink beam determination after a beam failure recovery (BFR) procedure in a beamforming system is proposed. For uplink (UL) transmission, the BS provides physical uplink control channel (PUCCH) resource configuration to UE. The configuration includes spatial relation information that indicates the spatial filter to be used by UE for the corresponding PUCCCH transmission. After BFR procedure is completed and before the first spatial relation information indication for a PUCCH resource is received by UE, a default UE TX beam for the PUCCH resource can be determined based on the UE TX beam used during the BFR procedure, e.g., the UE TX beam used to transmit a beam failure recovery request (BFRQ) during the BFR procedure.

Abstract: In one novel aspect, configurations for PDCCH transmission and reception with multiple transmission points are provided. The UE configures a PDCCH associated with a CORSET comprising multiple CCEs, partitions the CORSET into multiple TCI-state sets, wherein each TCI state set includes multiple CCE groups associated with corresponding TCI-state, which corresponds to a source TRP, activates one TCI state set, and receives DCI via the PDCCH, wherein the PDCCH is transmitted from at least the first source TRP and the second source TRP, and wherein each source TRP transmits corresponding portion of DCI data mapping to the corresponding first and second CCE group. The CORSET is partitioned in FDM or TDM way. In another novel aspect, a first and a second PDCCH associated with a first and a second TRP are configured for repetition transmission. The second PDCCH configuration is dependent upon the first PDCCH configuration.

Abstract: Examples pertaining to measurement resource and report configuration for a communication apparatus supporting device collaboration in mobile communications are described. A user equipment (UE) receives a first report configuration associated with at least a first measurement resource allocated in a first frequency band from a network node. The UE determines information regarding a second measurement resource allocated in a second frequency band which is different from the first frequency band. The UE receives a first radio frequency (RF) signal carrying one or more reference signals on the first measurement resource and receives a second RF signal carrying identical one or more reference signals on the second measurement resource.
