Abstract: Systems and methods for UE state machine to support multiple services or air interfaces are described. The UE may have one configuration of the state machine for multiple services or air interfaces. The UE may have multiple state machines for different services or air interfaces that work independently. The UE may have multiple state machines for different services or air interfaces that work collaboratively. The UE may have a state machine that uses a state machine configuration selected out of a plurality of state machine configurations according to the services used. The configuration of this state machine may be adapted to services. At initialization, the configuration of this state machine may be default or be determined according to the services the UE may use. During operation, the configuration of this state machine may change according to the change in services for the UE.

Abstract: A demodulation reference signal (DMRS) indicating method, a DMRS receiving method, and an apparatus are described. A transmit end determines, from a plurality of groups of demodulation reference signal DMRS configuration information, DMRS configuration information corresponding to a current DMRS transmission scheme. The transmit end obtains DMRS indication information based on the DMRS configuration information, where each group of DMRS configuration information includes a plurality of pieces of DMRSs configuration information. The transmit end sends the DMRS indication information. The described method and the apparatus are implemented to match a plurality of New Radio (NR) scenarios. The described operations can satisfy a requirement for transmitting more layers of data and reduce indication overheads.

Abstract: This application provides a data transmission method and an apparatus. The method includes: obtaining, by user equipment, to-be-sent user data; performing, by the user equipment, channel encoding on the to-be-sent user data to obtain N sets of encoded data; performing, by the user equipment, codebook mapping on each of the N sets of encoded data by using a codebook, to obtain N sets of codebook-mapped data, where different sets of encoded data use codebooks that occupy mutually different non-zero physical REs, the non-zero physical RE means a non-zero waveform obtained after mapped data is mapped to a physical RE, and N is a positive integer greater than or equal to 2; and sending, by the user equipment, the N sets of codebook-mapped data to a base station.

Abstract: Signal processing complexity in fifth generation (5G) networks can be reduced by communicating wireless signals over self-contained partitions of a carrier such that the wireless transmission communicated over each self-contained partition of the carrier includes all physical control channel signaling required to decode data carried in a physical data channel of the partition. The control signaling may include resource assignment within the partition, modulation and coding scheme indication, reference signal configuration and retransmission information. In some embodiments, an anchor partition of a carrier is used to communicate initial access information for self-contained partitions of the carrier. The initial access information may include center-frequencies, bandwidths, and/or air interface configurations of the self-contained partitions. The anchor partition may also carry load indications associated with the self-contained partitions.

Abstract: It is possible to reduce overhead when dynamically establishing an air interface configuration by communicating a modification instruction along with an index associated with a predefine air interface configuration. The modification instruction identifies a modification to one or more parameters of the predefined air interface configuration associated with the index. Together, the index and the modification indication specify a modified air interface configuration that is different than any of the candidate air interface configurations predefined for the network. The modification instruction allows networks to achieve similar degrees of flexibility while using substantially fewer predefined air interface configurations, which in turn permits the index associated with the selected air interface configuration to be signaled using fewer bits.
