摘要： A node classifies data packets into different classes and replicates the data packets according to a number of redundant links configured for transmission of the data packets to obtain, for each of the redundant links, a redundant version of the data packets. For a first one of the classes, the node marks all redundant versions of the data packets with a first indication that the data packet is a guaranteed data packet. For a second one of the classes, the node marks at least one of the redundant versions of the data packets with a second indication that the data packet is a guaranteed data packet and marks at least one other of the redundant versions of the data packets with a third indication that the data packet is a non-guaranteed data packet.

摘要： Method and apparatus for use within a wireless OFDM network that receives a first packet type in a first channel bandwidth and a second packet type in a second channel bandwidth, the first channel bandwidth being at least two times wider than the second channel bandwidth. The first packet type has a header field with two parts with each part comprising a different set of header bits. The two parts of the header field are received using two OFDM symbols. The second packet type has a header field with four parts with the first and second parts comprising the same first set of header bits and the third and the fourth part comprising the same second set of header bits. The four parts of the header field are received using four OFDM symbols. The second packet type provides more reliable reception than the first packet type.

摘要： Systems and methods are provided for deriving channel feedback for a physical channel based on an indication of the number of transmission repetitions. In some embodiments, a method for use in a wireless device for determining channel feedback for a physical channel includes receiving control signaling including an indication of a number of transmission repetitions of the physical channel. The method also includes deriving the channel feedback for the physical channel based on the indication of the number of transmission repetitions, where a code rate corresponding to the channel feedback corresponds to an effective channel code rate of the physical channel occupying a group of physical resources including the number of transmission repetitions. In this way, the wireless device may report channel conditions that are better than the channel conditions corresponding to a single transmission, according to some embodiments.

摘要： Modulated signal A is transmitted from a first antenna, and modulated signal B is transmitted from a second antenna. As modulated signal B, modulated symbols S2(i) and S2(i+1) obtained from different data are transmitted at time i and time i+1 respectively. In contrast, as modulated signal A, modulated symbols S1(i) and S1(i)′ obtained by changing the signal point arrangement of the same data are transmitted at time i and time i+1 respectively. As a result the reception quality can be changed intentionally at time i and time i+1, and therefore using the demodulation result of modulated signal A of a time when the reception quality is good enables both modulated signals A and B to be demodulated with good error rate performances.

摘要： A system is provided that can introduce data redundancy into wireless communications, and in particular ultra-wideband (UWB) wireless communications to increase the communication range when transmitting data that has low transmission rates. Multipath degradation, introduced by the extended communications range, can be mitigated by frequency hopping between the orthogonal frequency-division multiplexed symbols of the ultra-wideband waveform. Frequency hopping can place adjacent symbols in different frequency channels for filtering. Data redundancy can be expanded in the time domain and/or the frequency domain, resulting in extended range.

摘要： When receiving a first data frame sent by a transmitting apparatus, a receiving apparatus may return error indication information including an identifier of at least one erroneous codeword group to the transmitting apparatus if it is found that an error occurs in an initial codeword of the first data frame. The transmitting apparatus may obtain the erroneous codeword group and encode the erroneous codeword group, and retransmit a part of a sub check codeword obtained through encoding to the receiving apparatus. The receiving apparatus may obtain a third check matrix based on a first check matrix, a second check matrix, and a location of the at least one erroneous codeword group in the initial codeword, and re-decode the retransmitted partial sub check codeword and content of the first data frame together based on the third check matrix, so as to obtain a correct initial codeword.
