  • Publication number: 20220377736
    Abstract: Provided is a radio communication base station device which can prevent lowering of use efficiency of a channel communication resource for performing a frequency diversity transmission when simultaneously performing a frequency scheduling transmission and the frequency diversity transmission in a multicarrier communication. In the device, a modulation unit (12) executes a modulation process on Dch data after encoded so as to generate a Dch data symbol. A modulation unit (22) executes a modulation process on the encoded Lch data so as to generate an Lch data symbol. An allocation unit (103) allocates the Dch data symbol and the Lch data symbol to respective subcarriers constituting an OFDM symbol and outputs them to a multiplexing unit (104). Here, when a plurality of Dch are used for a Dch data symbol of one mobile station, the allocation unit (103) uses Dch of continuous channel numbers.

  • Publication number: 20220345961
    Abstract: The present disclosure relates to a user equipment (UE) that comprises a receiver of the UE receives, from a source base station of a source radio cell, a common timing advance value for a target radio cell. The UE is connected to the source radio cell and is involved in a handover procedure to hand over the UE from the source radio cell to the target radio cell. Further, the common timing advance value is received from the source base station in a first message of the handover procedure, which also comprises a timing indication for transmitting a second message from the UE to the target base station. Then, a processor of the UE determines a first uplink timing of uplink transmissions to the target base station with respect to downlink transmissions from the target base station, based on the received common timing advance value and the timing indication. A transmitter of the UE transmits a second message of the handover procedure to the target base station based on the determined uplink timing.

    Abstract: The invention relates to a method, apparatus and system for configuring control channels in a mobile communication network and a mobile station. In order to suggest another improved scheme for configuring control channels, in particular control channels related to the transmission of user data the invention suggests aligning the size of the control channel information of different formats to an equal number of coded control channel information bits and/or modulation symbols for each control channel. The control channels may comprise scheduling related control information. According to another aspect of the invention, the size of the control channel information is aligned by means of modulation and/or coding, however the control channel information is aligned to one out of a set of numbers of coded control channel information bits and/or modulation symbols for each control channel.

  • Patent number: 11477767
    Abstract: A radio terminal in a radio communication system receives a physical downlink control signal comprising a control field and a new data indicator (NDI) field and determines that a value of the NDI field is one of a first value and a second value. A physical uplink shared channel signal is generated according to both a specific transport format and a specific redundancy version. The control field is used to determine the specific transport format when the NDI field is determined to be the first value, and the control field is used to determine the specific redundancy version when the NDI field is determined to be the second value.

  • Publication number: 20220264485
    Abstract: Provided are a wireless communication terminal device and a power allocation method, wherein transmission channel quality information, regarding a Pcell having a high probability that UCI is multiplied therein, can be accurately estimated by an SRS having high priority in power allocation, and an eNB can instruct appropriate transmission power to an UL channel which transmits the subsequent UCI. A power scaling detection unit detects whether or not a total transmission power value of the UL channels transmitted by the plurality of CC exceeds the maximum transmission power specific to the UE. When a plurality of SRS are simultaneously transmitted using a Pcell and a Scell, and power scaling occurs, a power scaling control unit performs power allocation so that transmission power of the SRS of the Pcell has the higher priority than that of the SRS of the Scell.
