Abstract: Method and apparatus for transmitting downlink control information (DCI) are provided. The method includes: scheduling traffic channels in multiple transmission time intervals (TTIs) through a single DCI, where a subcarrier spacing of a carrier where the scheduled traffic channel is located is not smaller than a subcarrier spacing of a carrier where the DCI scheduling the traffic channel is located; and transmitting the DCI. A problem of how to use a multi-TTI scheduling for a cross-carrier scheduling in which a subcarrier spacing of a scheduling carrier is smaller than a subcarrier spacing of a scheduled carrier in the related art may be solved, and the effects of scheduling the multiple TTIs through a single DCI and reducing the overhead are achieved.

Abstract: The disclosure provides an information transmission method and apparatus. The method includes: carrying a first parameter in physical layer signaling corresponding to a Physical Downlink Shared Channel (PDSCH); and transmitting, according to an indication of the first parameter, a Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK) corresponding to the PDSCH, which may be specifically identifying an indication meaning of the current first parameter on a predetermined basis and selecting which positions are used to transmit the HARQ-ACK. By adopting the above solution, a first communication node itself sets a position at which an HARQ-ACK is transmitted, and a second communication node feeds back, according to an indication, the HARQ-ACK corresponding to a PDSCH in time, thereby solving the problem of greater delay for HARQ-ACK feedback in the related art, and ensuring the low delay processing of a service.

Abstract: Methods, systems, and devices for generating sequences for reference signals in mobile communication technology are described. An exemplary method for wireless communication includes transmitting data, which is modulated using a pi/2-binary phase shift keying (BPSK) modulation, and a reference signal using a plurality of subcarriers, where the reference signal comprises a sequence from a subset of sequences that contains 30 sequences, each with a predetermined length, and where the subset of sequences include at least a first number of fixed sequences and a second number of selected sequences. The method further enables constructing the sequences, which have low peak-to-average power ratio (PAPR) properties, for sequence lengths N=6, 12, 18, 24 and 30.

Abstract: A wireless communication method includes configuring, by a first communication node, a first set of parameters related to random access procedure by a second communication node on a first communication link between the first communication node and the second communication node, and receiving, from the second communication node, a random access signal that uses the first set of parameters on the first communication link. The first communication node also provides wireless connectivity to a third communication node via a second communication link that shares at least some transmission resources with the first communication link. The first set of parameters includes one or more of a random access format, a random access sequence index set, a random access sequence root sequence index, a random access cyclic shift, and random access time-frequency resources.
