Patent number: 9930665Abstract: Methods and apparatuses are provided for communication between a UE and a Node B in a communication system. The UE receives a control signal including one bit of frequency hopping information, a resource allocation type, a resource allocation, and a cyclic shift for a reference signal from the Node B. It is determined that the frequency hopping information is used as a part of resource allocation information, if the resource allocation type indicates that two sets of resource blocks are allocated. The UE transmits data based on the frequency hopping information, the resource allocation type, and the resource allocation included in the control signal. Each of the resource blocks comprises one or more resource block groups, and a size of each resource block group is determined based on an uplink bandwidth.Type: GrantFiled: June 22, 2015Date of Patent: March 27, 2018Assignee: Samsung Electronics Co., LtdInventors: Aris Papasakellariou, Joon-Young Cho, Ju-Ho Lee

Patent number: 9893849Abstract: In a base station, a control unit and a data size regulation unit control the data size of downstream assignment control data and upstream assignment control data in the PDCCH signal based on the communication format used between the base station and a terminal, the number of base station antennas (M) (nonnegative number), the number of terminal antennas (N) (nonnegative number), the bandwidth of the downstream band, and the bandwidth of the upstream band. Specifically, the control unit determines it is unnecessary to adjust the aforementioned data size when the selected communication format is first established between multiple antennas and when where there are multiple for one of M and N and only one for the other.
