摘要： An apparatus and method for feeding back hybrid automatic repeat request-acknowledgement (HARQ-ACK) information are provided. The apparatus and method include user equipment (UE) that first receives a downlink grant (DL-GRANT) which schedules downlink HARQ transmission in a time-frequency bundling window corresponding to an uplink subframe used for feeding back HARQ-ACK, obtains a DL downlink assignment index (DL DAI) in the DL-GRANT, and determines a mapping value of each DL DAI. Then, according to the mapping value of the corresponding DL DAI, the HARQ-ACK bit of each HARQ feedback unit is mapped to a corresponding bit of a feedback bit sequence. According to the method and apparatus provided by the present disclosure, useless HARQ-ACK bits may be effectively removed, and efficiency for feeding back HARQ-ACK may be increased. As such, a downlink peak rate of a UE is ensured.

摘要： A method of SRS transmission in a terminal in a mobile communications system using multiple antennas and a Sounding Reference Signal (SRS) hopping is disclosed. The method comprises generating an SRS to be transmitted to a base station. A transmission band is set for transmitting the SRS. An antenna index is determined for transmitting the SRS so that antennas which transmit the SRS are not overlapped in the same transmission band of a first transmission section and a second transmission section. Each transmission section comprises at least one transmission time point. The SRS is transmitted to the base station according to the antenna index and the transmission band. The number of the transmission time point within the transmission section corresponds to the number of the transmission bands.

摘要： The present disclosure provides a method for transmitting a synchronization signal (SS), the method comprising: performing a listen-before-talk (LBT) operation in a pre-defined window; if the LBT operation succeeds, transmitting an SS block (SSB) in the window, wherein the SSB comprises the SS, or the SSB comprises the SS and a physical broadcast channel (PBCH). Compared with the prior art, the present disclosure may significantly improve the efficiency of data transmission and the access performance for the communication system by relaxing the time when the base station implements the LBT, that is, allowing the base station to implement the LBT in the pre-defined window and transmit the SSB after the LBT succeeds.

摘要： A sounding reference signal transmission method which is efficient in an uplink wireless telecommunications system using a multiple antenna technique and sounding reference signal hopping. A terminal using the multiple antenna technique is equipped with a plurality of antennas, and a base station receives the sounding reference signal transmitted from these antennas and estimates the uplink channel state of each antenna. Moreover, the sounding reference signal performs frequency hopping so that the base station determines the channel condition for the entire bandwidth to which data is transmitted in the uplink system. The sounding reference signal is transmitted through an antenna pattern in which the sounding reference signal can be transmitted through the entire data transmission bandwidth of the uplink system for each antenna of the terminal without additional overhead in this environment.

摘要： A base station can communicate with a plurality of subscriber stations in a Multi-User (MU) Multiple-Input Multiple-Output (MIMO) system. The base station includes a transmitter and plurality of antenna configured to transmit control information. The base station can transmit a resource block to a first subscriber station. The resource block includes at least two downlink reference signal (DRS) patterns. The base station can assign a first DRS pattern for use by the first subscriber station. The base station informs the subscriber station regarding the assignment by reserving a state in a downlink grant. In response, the subscriber station can utilize the first DRS pattern as a pilot resource element and, optionally, avoid other DRS patterns.

摘要： A method for transmitting an uplink sounding reference signal includes indexing Single Carrier Frequency Division Multiple Access (SC-FDMA)symbols within a single radio frame for transmitting a Sounding Reference Signal (SRS) as a number k, and calculating a value of n SRS according to number k and an index number of the radio frames for transmitting the SRS, determining an index number of a frequency-domain start sub-carrier mapped from time-domain SRS symbol with n SRS , and transmitting the SRS through the sub-carrier with the determined index number determined. Before transmitting the SRS, the start frequency position for SRS should be changed according to the specific frequency-hop pattern to guarantee that the UE may uniformly sound the entire SRS frequency-hop bandwidth after multiple soundings.
