摘要:
A pilot selection method adapted for selecting rank-2 pilot patterns for a macrocell advanced base station (ABS), a femtocell ABS and a non-macrocell and non-femtocell ABS is proposed along with a wireless communication system and a base station thereof. Different rank-2 pilot pattern is selected for a femtocell ABS from its overlay macrocell ABS and non-macrocell and non-femtocell ABS rank-2 pilot patterns. Another pilot selection method for selecting a rank-1 pilot pattern for a femtocell ABS co-located with at least a macrocell ABS is also proposed. Different rank-1 pilot pattern is selected for a femtocell ABS from its overlay macrocell ABSs using rank-1 and/or rank-2 pilot patterns, where some of the macrocell ABSs can use rank-2 pilot patterns and the rest of the macrocell ABSs just use rank-1 pilot patterns. Also, different rank-1 pilot pattern is selected for the femtocell ABS from its neighboring femtocell ABSs using rank-1 pilot patterns.

摘要:
A method of providing resource unit based data block partitioning may include determining, for a bit stream to be encoded in a coding scheme including an upper layer coding and a physical layer coding, whether upper layer coding is enabled. The method may further include, in response to the upper layer coding being enabled, partitioning the bit stream into one or more blocks for forward error correction coding. The one or more blocks may have a block size determined based on a size of a resource unit. The resource unit size may correspond to one or more units predefined in the physical layer for the resource allocation. A corresponding apparatus is also provided.

A method of designing a reference signal pattern for a network in a wireless communication system is disclosed. The method comprises transmitting a plurality of cell-specific reference signal (CRSs) in a subframe, the subframe comprising a plurality of resource elements that are divided in time across a plurality of subcarriers to form a plurality of orthogonal frequency division multiplexed (OFDM) symbols, each of the plurality of resource element occupying a predetermined amount of time on a respective one of the plurality of subcarriers. wherein, a first set of the plurality of CRSs is allocated to a first set of the plurality resource elements on a first symbol and a second symbol over a third subcarrier, a sixth subcarrier, a ninth subcarrier and a twelfth subcarrier.

摘要:
An apparatus for data processing in a multi-channel communication system is provided. The apparatus includes an encoder configured to encode a number of bits for transmission via channels in the multi-channel communication system into coded bits and split the coded bits into a number of first sets of bits at a first ratio, a number of first rate units coupled to the encoder, each of the first rate units being configured to adjust one set of the first sets of bits in size at at least one rate, and a controller configured to assign the first ratio to the encoder and the at least one rate to each of the first rate units based on conditions of the channels.
