摘要： The set of resource aggregation levels available for forming an enhanced control channel message may vary from one subframe to another, based on the level of puncturing in the transmitted subframes. An example method begins with determining members of a set of aggregation levels usable to aggregate the non-overlapping subsets of resource elements for transmitting downlink control information. This determining is based on a puncturing level to be used for the transmission of the downlink control information. Downlink control information for the given subframe is mapped to one or more non-overlapping subsets of resource elements in the at least one block of time-frequency resources, according to an aggregation level selected from the determined set, and then transmitted, in the one or more non-overlapping subsets. This method may be repeated for each of several subframes, where the puncturing may differ from one subframe to another.

摘要： In a method of generating a field of a physical layer (PHY) preamble of a data unit, information bits to be included in the field are generated. Respective sets of tail bits are appended after respective sets of information bits corresponding to respective ones of a plurality of groups of subfields of the field, each group including one or more of the subfields of the field, to generate an encoder input bit stream. One or more padding bits are added to the encoder input stream to generate a padded encoder input bit stream, the one or more padding bits to ensure an integer number of puncturing blocks in an encoded output bit stream. The padded encoder input bit stream is encoded to generate the encoded output bit stream. The field is generated to include at least some bits from the encoded output bit stream.

摘要： Systems and methodologies are described that facilitate controlling interference in a heterogeneous wireless communication environment. A Physical Broadcast Channel (PBCH) transmission from an interfering base station can be punctured based upon a puncturing pattern as a function of a cell identifier (ID) and a transmit time. Puncturing can be effectuated by applying power control. Thus, a punctured symbol or subframe can have a reduced transmit power or a transmit power set to zero. Further, the puncturing pattern can be defined on a subframe basis or on a symbol basis.

摘要： Disclosed is an encoding processing apparatus in which reception precision characteristics are improved by specially adapting puncture processing in respect of the code words for each encoding system. A puncture section (130) switches between a puncture pattern for a first code word partial sequence obtained on the basis of the head and tail in a fixed information block, and a puncture pattern for a second code word partial sequence obtained on the basis of the middle portion, excluding the head and tail. Also, the puncture section (130) receives the number of retransmissions of information from a retransmission control section (180) and switches the puncture pattern for the second code word partial sequence in accordance with the number of retransmissions. In addition, the puncture section (130) prioritising systematic bits over parity bits when puncturing the first code word partial sequence.
