Various aspects described herein relate to techniques for frequency hopping for a wideband allocation in wireless communications. A wideband allocation of resources for transmitting uplink wireless communications can be determined, as well as a frequency hopping offset related to one or more narrowbands for transmitting uplink wireless communications. In addition, it can be determined whether to apply the frequency hopping offset to the wideband allocation in communicating data. The data can be communicated over resources related to the wideband allocation with the frequency hopping offset applied communicating, based on determining to apply the frequency hopping offset.

Disclosed are a mobile terminal, a base station and a non-transitory computer-readable medium to securely receive a signal. When the mobile terminal sends information, randomly implementing an XNOR calculation is randomly implemented on corresponding digits of a low-frequency digital sequence which is to transmit the information and a first cyclic PN sequence or a second cyclic PN sequence so as to obtain spread sequences. The spread sequences are modulated and sent. The base station or the mobile terminal receives the spread sequence, and despreads the same using the first and second cyclic PN sequences. The present invention effectively prevents lawbreakers from decoding and monitoring a communication process.
