METHOD FOR TRANSMITTING CONTROL AND TRAINING SYMBOLS IN MULTI-USER WIRELESS COMMUNICATION SYSTEM
The present invention relates to a method and an apparatus for transmitting control and training symbols to improve transmission efficiency in a multi-user wireless communication system. The method for transmitting the control and training symbols in the multi-user wireless communication system according to one embodiment of the present invention comprises the steps of: determining whether a required transmission rate of each data can be satisfied through channel estimation in each of terminals when different data are simultaneously transmitted to each of the terminals; and transmitting a data frame to each of the terminals, the data frame being composed to discriminate the control and training symbols in each of the terminals using a combination of time, frequency, and code area when the required transmission rate of each data is not satisfied according to the determined result.
USER TERMINAL
A user terminal according to an aspect of the present disclosure includes: a receiving section configured to receive a downlink shared channel transmitted from different transmission/reception points for each given number of repetitions; and a control section configured to control the reception of the downlink shared channel based on a transmission configuration indicator (TCI) state associated with a repetition among the given number of repetitions of the downlink shared channel or with a redundancy version of the downlink shared channel.

COMMUNICATION DEVICE AND METHOD USED FOR MULTI-USER SPATIAL MODULATION
A communication device includes a processing circuit, the processing circuit being configured as: mapping a first information bit part used for a receiving end to a corresponding channel based on a pre-set mapping rule so as to execute spatial modulation with respect to the first information bit part of the receiving end; allocating a transmission power to the receiving end; and controlling the transmission power allocated through a mapped channel to transmit a second information bit part used for the receiving end. In the case of the first information bit parts used for multiple receiving ends being the same, the channels mapped for multiple receiving ends are the same. The multi-user spatial modulation performs spatial modulation for multiple receiving ends at the same time through a multiplexing channel of the transmitting end, improving the additional modulation order and the data transmission rate which can be obtained by each receiving end.

Supporting or performing distribution of a paging message
A wireless device, a first network node and methods therein, for supporting or performing distribution of paging messages within a Radio Access Network Area, RANA, of a wireless network. The wireless device collects RANA related information from network nodes visited by the wireless device. The RANA related information indicates which RANAs are supported by the respective network nodes. A list of network nodes that support a RANA is extracted from the collected RANA related information, and the list is sent to the first network node to enable distribution of paging messages by the first network node within the RANA.
