Embodiments of the disclosure provide a method for scheduling shared physical resource blocks (PRBs) by a user equipment (UE) in a wireless network and minimizing/reducing contention on the shared PRBs. The method includes: receiving PRBs from a network device, where the PRBs are shared among multiple UEs in the wireless network; detecting data at the UE for transmission; determining a modulation and coding scheme (MCS), a number of PRBs, and a size of a transport block required for data transmission in response to detecting the data; self-scheduling the shared PRBs based on at least one of the determined MCS, the number of PRBs, and the size of the transport block; and sending the data based on the self-scheduling along with self-scheduling information to the network device.

A wireless device receives one or more radio resource control (RRC) messages. The RRC messages comprise configuration parameters, of a cell, indicating a first bandwidth part (BWP) and a second BWP. A first downlink control information (DCI) scheduling one or more first uplink resources for a first transmission of a first uplink transport block (TB) is received via the first BWP of the cell. A second DCI is received before the first transmission of the first uplink TB. The second DCI indicates: a switch from the first BWP to the second BWP of the cell; and one or more second uplink resources for a second transmission of a second uplink TB via the second BWP. The first transmission of the first uplink TB is cancelled.

A base station includes a transmit path circuitry to transmit an indication of whether a subscriber station is configured with precoding matrix indicator/rank indicator (PMI/RI) reporting. The transmit path circuitry sets a pre-coding granularity to multiple physical resource blocks in the frequency domain to perform a same pre-coding over a bundled resource block if the subscriber station is configured with PMI/RI reporting. The bundled resource block includes multiple consecutive physical resource blocks in the frequency domain. The base station also includes a receive path circuitry to receive feedback from the subscriber station.

The disclosure is related to a method and a system for selecting a communication interface. The method is applicable to a local area network including multiple access points. A main access point is first selected. The main access point acquires every access point's information within a local area network. The information relates to the access points that are in an idle state or not performing a critical task. A target antenna can be selected for performing a specific function. For example, the target antenna can be used to scan for the channels specified in dynamic frequency selection. After that, the scan result may result in changing channels. Through the above mechanism, the resources in every AP within the LAN can be adequately used, and the performance of wireless communication can be effectively improved.

A hybrid cellular and non-cellular multi-hop communication device, including a hand-held wireless device having one or more antennas, a cellular wireless interface connected to at least some of the one or more antennas, and a non-cellular wireless interface connected to at least some of the one or more antennas. The non-cellular wireless interface may include a rate allocator configured to select a physical-layer rate of transmission of data from the non-cellular wireless interface based on a queue length of data to be transmitted from the hand-held cellular device and a transmitter configured to wirelessly transmit data from the queue and adjust physical-layer transmission parameters based on a physical-layer rate selected by the rate allocator.

A base station, a processor thereof, and a communication control method thereof receive a notification from a first user terminal before starting direct device to device (D2D) communication, the notification indicating a desire for performing D2D communication, receive a measurement report including results of measurement of a cell reference signal from the first user terminal, and based on the measurement report, determine to cause the first user terminal to perform D2D communication, perform a process for starting the D2D communication between the first and second user terminals, receive a first data amount notification indicating an amount of first data to be transmitted from the first user terminal to the second user terminal, and based on the first data amount notification, allocate first radio resources to the first user terminal, where the allocated first radio resources are used by the first user terminal to transmit the first data.

Methods and devices are disclosed from the perspective of a first wireless transmit/receive unit (WTRU). In one method, the method includes triggering a first buffer status report (BSR), wherein the first BSR indicates an estimated amount of data expected to arrive.

A wireless communication network serves wireless user devices over a radio channel that is allocated into subchannels for wireless network slices. A wireless access node schedules resource blocks from the subchannels to the wireless user devices based on their wireless network slices. The wireless access node detects a subchannel has available resource blocks and other subchannels need the available resource blocks. The wireless access node schedules the available resource blocks to the wireless user devices that need the available resource blocks and that use a higher priority wireless network slice. The wireless access node wirelessly exchanges user data with the wireless user devices over the scheduled resource blocks and exchanges the user data with the wireless network slices. The wireless network slices exchanging at least some of the user data with external systems.

Methods, systems, and devices for on-demand multicast control channel (MCCH) messages are described. A user equipment (UE) may receive, from a base station, system information indicating an MCCH message configuration. Based on receiving the MCCH message configuration, the UE may transmit a request for an MCCH message. For example, the UE may transmit the request for the MCCH message by a random access preamble or a radio resource control (RRC) message. After transmitting the request, the UE may receive the MCCH message in accordance with the MCCH message configuration. That is, the base station may receive the request and transmit the MCCH message in response to the request. The MCCH message may indicate a multicast service radio bearer (MRB) configuration for receiving multicast traffic. Thus, the UE may receive multicast traffic from the base station in accordance with the MRB configuration.
