Abstract:
A method for transmitting and receiving data by a mobile station (MS), a method for transmitting and receiving data by a base station (BS), and a mobile communication terminal are provided. The method for transmitting and receiving data by an MS includes generating an uplink subframe by placing an uplink control channel so as to have a margin with a time allocated to a MAP of a downlink subframe and transmitting the uplink subframe to a BS. A new frame structure compatible with a full duplex FDD MS is applied in a mobile communication system.
Abstract:
A method of allocating an uplink radio resource includes transmitting a scheduling request signal for requesting allocation of the uplink radio resource, wherein the scheduling request signal comprises control information, a request of the allocation of the uplink radio resource is represented by transmitting the scheduling request signal and the control information is represented by a value of the scheduling request signal, and receiving a scheduling grant message in response to the scheduling request signal.
Abstract:
The present invention relates to allocating a radio resource in a wireless communication system utilizing orthogonal frequency division multiplexing (OFDM). Preferably, the present invention comprises receiving in a mobile station data associated with a radio resource allocation map from a base station, wherein the radio allocation map comprises control parameters for transmitting an uplink channel, wherein the uplink channel comprises at least one OFDM tile comprising a first set of subcarriers associated with representing at least part of an n-bit data payload, and a second set of subcarriers associated with representing at least part of a non-pilot m-bit data payload wherein each subcarrier carries a modulated data, and the first and the second set of subcarriers are exclusive to each other, and transmitting the uplink channel from the mobile station to the base station.
Abstract:
A method for transmitting and receiving a control channel with additional information is disclosed. To this end, a mobile station acquires information of at least one control channel, which supports additional information transmission through phase rotation, and phase rotation value information for representing the additional information, and transmits control information through any one of the control channels and the additional information through phase rotation of the control information. A base station provides information of at least one control channel, which supports additional information transmission through phase rotation, and phase rotation value information for representing the additional information, and simultaneously receives specific control information and additional information from the mobile station based on the control channel information and the phase rotation value information.
Abstract:
A method of transmitting and receiving data in a wireless communication system is disclosed. According to an embodiment of the present invention, a base station (BS) transmits downlink data to a first mobile station supporting a first system via a first zone of a frame and transmitting downlink data to a second mobile station supporting a second system via a second zone located behind the first zone by a frame offset on a time axis, wherein the first zone includes the odd number of OFDM symbols and wherein the frame offset is an offset between a start point of a frame for the first system and a start point of a frame for the second system.
Abstract:
A method for transmitting/processing data in a wireless communication system, and a transmitter are disclosed. A method processing method for data transmission at a transmitting side of a wireless communication system employing multiple carriers comprises performing a symbol mapping process on a binary data sequence, and generating a symbol sequence, converting the symbol sequence into a time-domain symbol using a plurality of sub-carriers having a variable sub-carrier spacing therebetween, and adding a cyclic prefix to the time-domain symbol.
Abstract:
The present invention relates to allocating data regions in an orthogonal frequency division multiplexing access system. The present invention comprises receiving a message comprising information for locating a data region of a data map allocated to a mobile station identified in the message for transmitting and receiving information, and identifying the data region of the data map allocated to the identified mobile station by reading the received message, wherein the data region is identified independent of identifying data regions of another data map.
Abstract:
A method of transmitting feedback information in a wireless communication system is disclosed. More specifically, the method comprises a mobile station (MS) which determines whether to transmit feedback information to a base station (BS) without solicitation from the BS. After determining to do so, the MS transmits a request message to request the BS to allocate an uplink resource for transmitting at least one unsolicited header and thereafter receives the uplink resource allocation from the BS. Lastly, the MS transmits the at least one unsolicited header via the allocated uplink resource.
Abstract:
A method for transmitting control messages is disclosed. The method includes grouping a plurality of control messages for at least one user equipment based on at least one criteria of whether or not uplink ACK/NACK channel indexes are allowed to be implicitly used in the control messages, whether or not the user equipment corresponding to the control messages is able to implicitly use the uplink ACK/NACK channel indexes, sizes of Information Elements (IEs) of the control messages, whether or not the control messages are segmented into a predetermined number of subblocks, MCS levels applied to the control messages, sizes of allocated IEs of the control messages after applying the MCS levels, and frequency partitions in which the IEs of the control messages are present, and transmitting the grouped control messages. The control messages included in each of the groups generated by grouping are equal in at said least one criteria.
Abstract:
A method of transmitting control signals includes configuring a multiplexing indicator indicating that a plurality of control signals are multiplexed on a control channel, generating a multiplexed control signal by multiplexing a first control signal and a second control signal according to the multiplexing indicator and transmitting the multiplexed control signal on the control channel. Overhead due to control signaling can be reduced by transmitting a multiplexed control signal on a control channel.
