Abstract: Provided is a transmitter which improves the flexibility of SRS resource allocation without increasing the amount of signaling for notifying the cyclic shift amount. In the transmitter, with regard to each basic shift amount candidate group having a basic shift amount from 0 to N?1, a transmission control unit (206) specifies the actual shift amount imparted to a cyclic shift sequence used in scrambling a reference signal transmitted from each antenna port, said specification being performed based on a table in which cyclic shift amount candidates correspond to each antenna port, and based on setting information transmitted from a base station (100). With regard to basic shift amount candidates for shift amount X, the table differentiates between an offset pattern comprising offset values for cyclic shift amount candidates corresponding to each antenna port and an offset pattern corresponding to basic shift amount candidates of X+N/2.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device, such as a user equipment (UE), may receive a message that includes downlink control information (DCI) pertaining to system information that is scheduled to be received from a base station. The UE may determine, based at least in part on the message, whether the system information that is scheduled is remaining minimum system information (RMSI) or is other system information (OSI), and searching a downlink bandwidth part for the scheduled RMSI or OSI determined from the message. The described techniques may serve to resolve ambiguity between RMSI and OSI, for instance, when scheduled in the same control region and having overlapping search spaces.

Abstract: Embodiments of the present application provide a method and a device for transmitting data, which are capable of achieving timely data transmission. The method includes: starting, by a receiving end, a timer of a first delivery mode when determining that data delivered and data to be delivered are not continuous, where the first delivery mode is used to indicate that the receiving end directly delivers data to an upper layer upon the receipt of the data; and delivering, the receiving end, the data to be delivered to the high level using the first delivery mode in a case where the timer of the first delivery mode does not expire.

Abstract: Intelligent hybrid automatic repeat request (HARQ) feedback can better support link adaption. Thus, in addition to the traditional HARQ feedback, which is to relay acknowledgement (ACK) and negative acknowledgement (NAK) data based on a decoding result, a new state for the HARQ feedback can be represented as “ACK+”. Consequently, ACK+ can be used to indicate to the network that a modulation and coding scheme (MCS) of a current data packet is too conservative, and the user equipment (UE) is capable of supporting a more aggressive MCS.
