Methods and apparatuses for random access procedure. A method at a terminal device comprises receiving information of a physical uplink shared channel (PUSCH) resource allocation mode from a network node. The PUSCH resource allocation mode includes at least one of interlace or non-interlace. The method further comprises transmitting a first message including a random access preamble and payload to the network node. The payload is transmitted on a PUSCH based on the PUSCH resource allocation mode.

Proposed in the present specification is a method for transmitting and receiving urgent information in a wireless communication system supporting machine type communication, and a device for same. Specifically, a method performed by a terminal may include the steps of: receiving information including a Reference Signal Received Power (RSRP) threshold value from a base station; determining a Coverage Enhancement (CE) mode on the basis of the RSRP threshold value and an RSRP measurement value; determining a Physical Random Access Channel (PRACH) resource on the basis of the CE mode; and transmitting a PRACH preamble to the base station on the basis of the PRACH resource.

A wireless device receives: a first maximum total transmit power allowed for a first cell group of a first type of radio access technology; and a second maximum total transmit power allowed for a second cell group of a second type of radio access technology. It is determined that a total transmission power exceeds a value based on: a first power for transmission of first uplink signal(s) via the first cell group, and a second power for transmission of second uplink signal(s) via the second cell group. The first and second powers are less than or equal to the first and second maximum total transmit powers respectively. Scheduled transmission of the first uplink signal(s) of the first cell group is dropped in response to the first cell group being of the first type of radio access technology. Second uplink signal(s) are transmitted to a base station.

A resource management method performed by a CP in C-RAN system includes configuring M user-centric cells for M terminals with a plurality of ANs, and determining a number K of orthogonal resource sharing groups sharing a same orthogonal resource; selecting K user-centric cells as group headers for the K orthogonal resource sharing groups, and adding the selected K user-centric cells as group headers to the K orthogonal resource sharing groups; configuring the K orthogonal resource sharing groups by sequentially adding ungrouped user-centric cells to the K orthogonal resource sharing groups; and dividing total system resources into K orthogonal resources, and mapping the divided K orthogonal resources to the K orthogonal resource sharing groups, respectively.

One example method includes receiving configuration information of a control channel resource set, where the configuration information indicates a quantity of time-frequency resource blocks of the control channel resource set and an offset from a frequency domain center location of a synchronization signal block to a frequency domain center location of the control channel resource set, the synchronization signal block includes broadcast information and a synchronization signal, and the broadcast information includes the configuration information. The control channel resource set is determined based on the quantity of time-frequency resource blocks and the offset, and control information is received within the control channel resource set.

Aspects relate to reporting channel state information (CSI) for a plurality of multiple transmission and reception points (TRPs) in a communication system. Downlink (DL) channels received from multiple TRPs are measured and a plurality of transmission hypotheses based on the measured DL channels from the multiple TRPs. The CSI is transmitted to a network in the communication system and includes a precoding matrix indicator (PMI) having at least a spatial domain basis matrix that is common to all of the transmission hypotheses and at least one coefficient matrix that is based on the spatial domain basis matrix.

The present disclosure describes a method, an apparatus, and a computer readable medium for a multilayer transmission in a wireless network. For example, the method may include generating a group of binary data bits for resources of each layer of a plurality of layers, mapping the group of binary data bits of each layer of the plurality of layers to respective code words in a signal constellation, combining the code words, and transmitting the combined code word to receiver in the wireless network. As such, the multilayer transmission in a wireless network is achieved.

The UE may further be configured to determine, when communicating with the at least one base station in the FD mode, FD UE assistance information including one or more FD UE assistance parameters. The UE may also be configured to transmit, to the at least one base station, an indication of the determined FD UE assistance information including the one or more FD UE assistance parameters. In some aspects, the apparatus may be a base station configured to communicate with at least one UE operating in a FD mode. The base station may further be configured to receive, from the at least one UE, an indication of FD UE assistance information including one or more FD UE assistance parameters.

A first communication device receives one or more aggregate medium access control (MAC) data units from respective one or more second communication devices. Respective aggregate MAC data units include multiple MAC data units from respective ones of the one or more second communication devices. The first communication device generates one or more acknowledgement information fields, including a first acknowledgement information field corresponding to a particular second communication device includes i) a length indication that indicates a length of an acknowledgement field, and ii) the acknowledgment field of the indicated length. The acknowledgement field includes respective acknowledgement information for at least some of the multiple MAC data units received from the particular second communication device. The first communication device generates an acknowledgement data unit to include the one or more one or more acknowledgement information fields, and transmits the acknowledgment data unit to the one or more second communication devices.

In the base station (100), a receiver (112) receives a transmission signal to be repeatedly transmitted over a plurality of allocation units, and a reception signal processor (114) demodulates the transmission signal based on a combination of non-orthogonal multiple access where signals of a plurality of terminals are not orthogonal with each other, and orthogonal multiple access where signals of a plurality of terminals are orthogonal with each other.
