    摘要: According to an example embodiment, a method may include determining, by a first wireless node in a wireless network, a number N of resource blocks available for transmitting data within a cell, the N resource blocks each including V resource block orthogonal frequency division multiplexing (OFDM) symbols, the V resource block OFDM symbols each including U resource block subcarriers. The method may also include mapping the N resource blocks into N subchannels based on a permutation formula, the permutation formula assigning, based on permutation parameters including the number N and a random or pseudorandom variable, U subchannel subcarriers for each of V subchannel OFDM symbols to each of the N subchannels and thereby allocating a subchannel index for each of the N subchannels. The method may also include sending a message to a second wireless node indicating the permutation parameters and the allocated subchannel index of at least one of the N subchannels for communication between the first wireless node and the second wireless node.

    摘要: M physical resource blocks PRBs are allocated for localized resource allocation LRA and N−M PRBs are allocated for distributed resource allocation DRA. Each PRB has U subcarriers. Subcarriers of the N PRBs are permuted to result in N subchannels. Serially for each mth one of the M PRBs allocated for LRA, the subcarriers for an mth one of the M PRBs allocated for LRA are punctured from the permuted subchannels. After puncturing, subcarriers of one of the subchannels are filled with subcarriers of all other subchannels which were punctured in the mth one of the M PRBs. The result after puncturing and filling for all M PRBs allocated for LRA is N−M PRBs each having U subcarriers and M PRBs each having U subcarriers. Then there is a wireless communication using at least one of a LRA on the resulting M PRBs or a DRA on the resulting N−M PRBs.

    摘要: A pair of slide cutting shears that have identical cutting angles of approximately 53 degrees on the thumb and finger blades, and where the thumb blade has approximately only 40% of the top end of the blade sharpened and the remaining section of the working blade is radiused and cannot cut. The shears have a four finger grip, and adjustable bump stop and a tightenable pivot pin assembly to draw the blades closer.
