A method performed by a UE is provided. The method determines a first size of a first DCI format and a second size of a second DCI format monitored in a common search space (CSS). The method determines a third size of the first DCI format and a fourth size of the second DCI format monitored in a USS. The method aligns the first size with the second size, and aligns the third size with the fourth size. The method determines at least one of a size of a third DCI format and a size of a fourth DCI format monitored in the USS, and adjusts at least one of the determined sizes of the third and fourth DCI formats, such that the adjusted size is not equal to any of the aligned first size, the aligned second size, the aligned third size, or the aligned fourth size.

This application discloses a packet loss management method. The method includes: A controller determines, based on a network quality requirement of service traffic and a network quality parameter of each segment link on a forwarding path of the service traffic, a packet loss concealment policy that needs to be executed on each segment link on the forwarding path, and delivers the packet loss concealment policy for each segment link to a forwarding node, and the forwarding node executes the corresponding packet loss concealment policy.

This application presents an adaptive data recovery from distorted signals (ADRDS) of original data symbols from intervals or parameters of tone signals derived from a received OFDM signal, including responding to dynamic distortions introduced to the received OFDM signal by an OFDM transmission channel. Such ADRDS is implemented by converting back the derived intervals or parameters into original data symbols corresponding to distinctive sets of the intervals or parameters which the derived intervals or parameters belong to.

An adaptive downlink control channel structure is provided to enable a transmitter to switch between forward error correction codes that use either Chase combining or incremental redundancy hybrid automatic repeat request (HARQ) techniques. Chase combining HARQ can be more efficient for forward error correction codes that use higher code rates, while incremental redundancy can be more effective for forward error correction codes that use lower code rates. The transmitter will also selectively comprise the redundancy version indicator bits depending on the HARQ method selected, which can reduce the sizes of the transport blocks when not using incremental redundancy. A receiver device can also decode transport blocks and determine whether a redundancy version indicator is present based on the forward error correction code selected.

A packet analysis apparatus, method, and non-transitory computer readable medium thereof are provided. The packet analysis apparatus stores a plurality of packets whose formats are unknown. The packet analysis apparatus calculates a plurality of cross-correlation values of the packets. The packet analysis apparatus decides at least one group according to the cross-correlation values and at least one first threshold, wherein each group includes a subset of the packets. The packets included in a specific group of the groups define a plurality of bit positions. Each packet included in the specific group has a plurality of bits. For each of the bit positions, the packet analysis apparatus calculates a variation degree of the bits corresponding to the bit positions. The packet analysis apparatus selects the at least one bit position whose variation degree(s) is/are smaller than a second threshold as at least one field boundary of the specific group.

The present invention relates to providing control information within a search space for blind decoding in a multi-carrier communication system. In particular, the control information is carried within a sub-frame of the communication system, the sub-frame including a plurality of control channel elements. The control channel elements may be aggregated into candidates for blind decoding. The number of control channel elements in a candidate is called aggregation level. In accordance with the present invention, the candidates of lower aggregation levels are localized, meaning that the control channel elements of one candidate are located adjacently to each other in the frequency domain. Some candidates of the higher aggregation level(s) are distributed in the frequency.
