Abstract: A method and device for controlling call forwarding are provided. In the method for controlling call forwarding, a call request is received, where the call request is sent when a second terminal takes a first terminal as a call forwarding destination; whether the first terminal permits reception of the call request forwarded from the second terminal or not is judged; and under a condition that a judgment result is that the first terminal does not permit the reception of the call request forwarded from the second terminal, the call request is denied.

Abstract: Techniques are described for selecting root pairs for Zadoff-Chu sequences for random access preamble and for signaling one or more values associated with the root pair to a user equipment (UE) by a base station. The described root pair selection methods for two-root physical random access channel (PRACH) preamble can enable the peak differences received at the UE from different frequency offsets (FOs) to be disjointed even considering error in UE side. The selection techniques can improve the performance of PRACH FO and time offset (TO) estimation.

Abstract: Methods, systems, and devices for the design of symbol-group based spreading schemes are described. An exemplary method for wireless communication includes transmitting, by a terminal, a first spread signal that is generated by spreading a first group of N data symbols using a first set of N sequences, where N is a symbol-group length, L is a spreading length, each of the first set of N sequences is from an orthogonal spreading sequence set that comprises L sequences, and each of the L sequences is of length L. Another exemplary method for wireless communication includes transmitting, by a network node, an indication of a first set of N sequences, and receiving a first spread signal comprising a group of N data symbols spread using the first set of N sequences.

Abstract: Optimizing the resource configuration or selection for grant-free contention-based non-orthogonal multiple access (NOMA) transmissions is an effective way to increase network capacity and reduce multi-user interference at the user equipment (UE). In some embodiments, a network node may determine the current traffic load, select multiple access (MA) sequences for the UE based on the determination, and transmit this selection to the UE for subsequent transmissions. In other embodiments, the UE may receive a message with an indication of the traffic load being experienced by the base station that the UE is attempting to connect to, and then may randomly select an MA sequence for subsequent transmissions.
