A method and device are disclosed from the perspective of a first device. In one embodiment, the method includes the first device being configured with a Sidelink (SL) Discontinuous Reception (DRX) configuration. The method also includes the first device performing a sidelink communication with a second device. The method further includes the first device receiving a signaling, from the second device, indicating a new sidelink transmission. In addition, the method includes the first device determining whether to start or restart a timer in response to the signaling at least based on information indicated in the signaling, wherein the first device monitors sidelink control channel when the timer is running.

A terminal according to an embodiment of the present invention can: encode a plurality of UCIs comprising a first UCI and a second UCI; perform resource mapping on the encoded bits of the plurality of UCIs on a single physical uplink channel; and perform uplink transmission on the basis of the resource mapping. Even when the first UCI and the second UCI have different priorities, the terminal can separately encode the first UCI and the second UCI on the basis that the first UCI and the second UCI are configured to be multiplexed on the single physical uplink channel, and perform the resource mapping on the second UCI having the lower priority on the basis of the resource mapping of the first UCI having the higher priority.

Methods and apparatuses are provided for determining a resource for an acknowledgement signal in a wireless communication system. A transceiver of a user equipment (UE) receives a parameter associated with one or more resource blocks (RBs) for periodic transmission of a channel quality indication (CQI) signal in an operating bandwidth. A controller of the UE determines an RB for transmission of the acknowledgement signal, based on the parameter. The transceiver transmits the acknowledgement signal on the determined RB. The RB for the transmission of the acknowledgement signal is not more outer than the one or more RBs for periodic transmission of the CQI signal in the operating bandwidth.

A radio communication device capable of randomizing both inter-cell interference and intra-cell interference. In this device, a spreading section primarily spreads a response signal in a ZAC sequence set by a control unit. A spreading section secondarily spreads the primarily spread response signal in a block-wise spreading code sequence set by the control unit. The control unit controls the cyclic shift amount of the ZAC sequence used for the primary spreading in the spreading section and the block-wise spreading code sequence used for the secondary spreading in the spreading section according to a set hopping pattern. The hopping pattern set by the control unit is made up of two hierarchies. An LB-based hopping pattern different for each cell is defined in the first hierarchy in order to randomize the inter-cell interference. A hopping pattern different for each mobile station is defined in the second hierarchy to randomize the intra-cell interference.

The teachings herein present a method and apparatus that implement and use a factorized precoder structure that is advantageous in terms of performance and efficiency. In particular, the teachings presented herein disclose an underlying precoder structure that allows for certain codebook reuse across different transmission scenarios, including for transmission from a single Uniform Linear Array (ULA) of transmit antennas and transmission from cross-polarized subgroups of such antennas. According to this structure, an overall precoder is constructed from a conversion precoder and a tuning precoder. The conversion precoder includes antenna-subgroup precoders of size N.sub.T/2, where N.sub.T represents the number of overall antenna ports considered. Correspondingly, the tuning precoder controls the offset of beam phases between the antenna-subgroup precoders, allowing the conversion precoder to be used with cross-polarized arrays of N.sub.T/2 antenna elements and with co-polarized arrays of N.sub.T antenna elements.

A radio resource configuration method and device are disclosed. The radio resource configuration method includes: after a piece of user equipment UE establishes a connection with a base station according to a system bandwidth in a broadcast message, determining, by the base station for the UE, resource configuration used for communication between the UE and the base station, where the resource configuration includes at least one of a resource allocation bandwidth, a channel state information CSI pilot bandwidth, and a CSI measurement bandwidth, where the resource allocation bandwidth is a bandwidth used to generate resource block allocation information in downlink control information; and sending, by the base station to the UE by using dedicated signaling or a common message, the resource configuration determined for the UE and used for communication between the UE and the base station.

A user equipment detects that an aggregate of calculated uplink transmit power of the UE exceeds a threshold. In response to the detecting, a power of at least one of a plurality of frequency-division multiplexing (FDM)-based uplink transmissions of the UE over corresponding wireless connections with respective wireless access network nodes is adjusted.

The disclosure discloses a method for Device to Device (D2D) resource pool measurement and reporting. A User Equipment (UE) measures a D2D resource pool, and sends measurement information of the D2D resource pool. The disclosure also discloses another method, Evolved Node B (eNodeB), UE and storage medium for D2D resource pool measurement and reporting.

For CSI reporting mechanisms, a user equipment (UE) includes a transceiver and a processor operably connected to the transceiver. The transceiver is configured to receive channel state information (CSI) process configuration information including at least one beamformed type associated with a plurality of non-zero-power (NZP) CSI reference signal (CSI-RS) resource configurations and receive a CSI-RS resource index (CRI) reporting configuration. The processor is configured to calculate, in response to receipt of the configuration information, a CRI and a channel quality indicator (CQI). The transceiver is further configured to report the CRI and the CQI by transmitting the CRI and the CQI on an uplink channel.

Methods and devices in a wireless communication system are provided. A radio resource control (RRC) reconfiguration message configuring a medium access control (MAC) parameter for the terminal, is received from a base station. An uplink grant on a physical downlink control channel (PDCCH) is received from the base station. A generation of a MAC protocol data unit (PDU) is skipped for the uplink grant in case that skip uplink transmission information indicating the terminal to skip an uplink transmission is configured in the RRC reconfiguration message, the PDCCH is addressed to a cell radio network temporary identifier (C-RNTI), a MAC service data unit (SDU) for the MAC PDU does not exist, and the MAC PDU includes only a padding buffer status report (BSR).
