Low power downlink control channel monitoring
Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may monitor sets of decoding candidates over a search space in each monitoring occasion to detect downlink control transmissions. Such a monitoring process may be resource intensive. To reduce the processing power involved in monitoring the control channel, a UE may measure resources associated with the downlink control channel to obtain a quality metric. The UE may compare the quality metric to one or more thresholds and may perform a decoding process on a set of configured decoding candidates for the downlink control channel based on the comparing. In some cases, if the channel quality is relatively good, the UE may perform a list decoding process using a list size less than a maximum list size or may perform partial data tone processing to reduce the processing complexity for some of the decoding candidates.
Receiving apparatus and decoding method
A decoding method includes: receiving a plurality of subcarrier signals each including encoded data; acquiring a predetermined amount of data from each of the plurality of subcarrier signals; correcting errors in the plurality of subcarrier signals by performing decoding arithmetic processing on the respective predetermined amounts of data acquired from the plurality of subcarrier signals in a time-division manner; and causing the decoding arithmetic processing to be consecutively performed on each of the predetermined amounts of data a predetermined number of times.
Systems And Methods For Nyquist Error Correction
The present invention is directed to communication systems and methods. In a specific embodiment, the present invention provides a receiver that includes an error correction module. A syndrome value, calculated based on received signals, may be used to enable the error correction module. The error correction module includes an error generator, a Nyquist error estimator, and a decoder. The decoder uses error estimation generated by the Nyquist error estimator to correct the decoded data. There are other embodiments as well.
Resource-Efficient Custom Downlink Search-Space in 5G/6G
In 5G and 6G, a user device is expected to perform an arduous blind search in each downlink control space to detect its DCI (downlink control information) messages. To save energy and complexity, especially for reduced-capability IoT applications, low-complexity procedures are disclosed that enable each user to request a custom search-space comprising one or more specific times and frequencies. Each downlink control or data message then starts in the custom search-space. The data or control messages may include the user's ID code, in plain text (as opposed to complex encoding) and/or the length of the message, so that the user can readily identify its messages. The user device may thereby readily separate its messages from the stream of incoming data. Result: saved time and energy, fewer dropped messages, and generally improved network performance, especially for simpler processors and devices.
