摘要： Methods and apparatus disclosed herein enable a half-duplex, HD, wireless communication device, WCD (16), to remain synchronized to a supporting communication network (10), during uplink transmissions that use a large repetition factor, also referred to a using a large bundle size. For example, the WCD (16) uses a rule whereby the WCD (16) tunes back to the downlink carrier from time to time while making an uplink transmission that uses a large repetition factor. Re-tuning to the downlink carrier from time to time in this manner allows the WCD (16) to correct and maintain its time and frequency synchronization with respect to the network (10).

摘要： The solution presented herein discloses a method of reducing inter-symbol jitter caused while processing each of a plurality of OFDM symbols in a received signal. For each of the plurality of OFDM symbols, the method comprises receiving a plurality of radio samples produced by a sampling of an OFDM symbol at a reduced sampling rate, where the reduced sampling rate causes inter-symbol jitter between the plurality of OFDM symbols. The method further comprises determining a sample offset corresponding to a symbol number for the OFDM symbol, transforming the samples of the OFDM symbol into a plurality of frequency-domain resource elements, and determining a phase offset for each of the resource elements using the sample offset. The method then reduces the inter-symbol jitter by rotating each resource element using the corresponding phase offset to generate phase-rotated resource elements. Corresponding narrow-band wireless receiver, narrow-band wireless receiver apparatus, jitter compensation circuit and computer program product are also disclosed.
