Mobile communication system, user equipment and base station
The present invention has an object to provide a communication system capable of minimizing effects due to a delay among a plurality of base station devices as much as possible in scheduling for communication with a terminal device in cooperation among the plurality of base station devices. Cells1 to 3 can each perform scheduling without using information for scheduling notified from one or a plurality of cells among pieces of information for scheduling notified from other cells. For example, in a case where an interface between the cell1 and cell3 has a large delay amount, the cell1 performs scheduling without using information S13 notified to the cell1 by the cell3, and the cell3 performs scheduling without using information S11 notified to the cell3 by the cell1.
Resource allocation for transmission with configured grant in unlicensed spectrum
Methods and devices are provided that enable configuration of a selected set of electronic devices (EDs) that are allocated the same time-domain resources and either orthogonal or the same frequency interlaces on a same unlicensed channel. Configuring the selected set of EDs in order to align transmission starting points in the unlicensed channel and utilizing blocking symbols for at least some of the transmission starting points, may mitigate mutual blocking during LBT procedures.
Sidelink multi-user multiple input multiple output
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of one or more reception parameters, of the UE, for sidelink communication and downlink communication. The UE may receive, based at least in part on the one or more reception parameters, at least one of one or more sidelink streams or one or more downlink streams. Numerous other aspects are provided.
Radio link monitoring in a multi-TRP scenario
A wireless device receives one or more radio resource control messages comprising configuration parameters for a cell. The configuration parameters indicate a plurality of coreset groups corresponding to a plurality of transmission and reception points (TRPs). Each coreset in the plurality of coreset groups is associated with a transmission configuration indicator (TCI) state. A coreset group of the plurality of coreset groups is selected for a radio link monitoring of the cell. The selection is in response to the coreset group comprising a coreset with a pre-defined index value. One or more reference signals are monitored based on one or more TCI states of one or more coresets of the coreset group.
Operating with multiple schedulers in a wireless system
Systems and methods are disclosed for a WTRU to operate using multiple schedulers. The WTRU may exchange data with the network over more than one data path, such that each data path may use a radio interface connected to a different network node and each node may be associated with an independent scheduler. For example, a WTRU may establish a RRC connection between the WTRU and a network. The RRC connection may establish a first radio interface between the WTRU and a first serving site of the network and a second radio interface between the WTRU and a second serving site of the network. The RRC connection may be established between the WTRU and the MeNB and a control function may be established between the WTRU and the SCeNB. The WTRU may receive data from the network over the first radio interface or the second radio interface.
METHOD FOR TRANSMITTING POWER HEADROOM, TERMINAL DEVICE, AND NETWORK DEVICE
A method for transmitting a power headroom, a terminal device, and a network device are provided. The method includes: sending a power headroom PH value of a serving cell to a network device, where the PH value is a first PH value of a first sounding reference signal SRS and/or a second PH value of a second SRS; and the first PH value is obtained based on first configuration information of the first SRS, the first SRS is an SRS used for positioning, and the second SRS is an SRS used for measurement.
SLEEP INDICATION METHOD, USER EQUIPMENT, NETWORK SIDE DEVICE AND STORAGE MEDIUM
The present disclosure provides a sleep indication method, a UE, a network side device and a storage medium. The sleep indication method includes: receiving, by a UE, first information, the first information being used to indicate to perform a PCell sleep behavior; and performing, by the UE, the PCell sleep behavior for a PCell in accordance with the first information.
Apparatus and Methods for Transmission and Reception of Data in Multi-Antenna Systems
Methods and apparatus adapted to address asymmetric conditions in a multi-antenna system. In one embodiment, the multi-antenna system comprises a wireless (e.g., 3G cellular) multiple-input, multiple-output (MIMO) system, and the methods and apparatus efficiently utilize transmitter and receiver resources based at least in part on a detected asymmetric condition. If an asymmetric condition is detected by the transmitter on any given data stream, the transmitter can decide to utilize only a subset of the available resources for that stream. Accordingly, the signal processing resources for that data stream are adapted to mirror the reduction in resources that are necessary for transmission. The transmitter signals the receiver that it will only be using a subset of the resources available, and the receiver adapts its operation according to the signaling data it receives. The multi-antenna system can therefore reduce power consumption as well as increasing spectral efficiency on the network.
Dynamic single frequency network area with listen before talk uncertainty
Methods, systems, and devices for wireless communications are described. A base station may determine a transmission beam configuration for transmitting multicast data to a user equipment (UE) in a joint transmission using a set of transmission/reception points (TRPs) based on outcomes of listen before talk (LBT) procedures performed at the TRPs. In some examples, the base station may indicate to the UE that the UE is to determine a UE beam configuration and a quasi co-location (QCL) relationship associated with the TRPs for receiving the multicast data based on signaling from the TRPs. In some examples, the base station may transmit multicast data from a first TRP (e.g., a serving cell) during a first transmission opportunity (TxOP), and the UE may determine the QCL relationship for the set of TRPs. During a second TxOP, the base station may transmit multicast data in a joint transmission from the set of TRPs.
Methods, Terminal Device and Base Station for Random Access Procedure
Methods, a terminal device and a base station for random access procedure are disclosed. According to an embodiment, the terminal device determines a frequency hopping configuration for transmission of one or more physical uplink shared channels (PUSCHs) in a request message for random access. The terminal device transmits the one or more PUSCHs in the request message based on the frequency hopping configuration. The request message at least comprises a physical random access channel (PRACH) preamble and the one or more PUSCHs.
