摘要:
This invention extends the coverage and improves the capacity of wireless communication networks using relay nodes. The relay nodes are wirelessly connected to the base station. The base station uses the same radio access technology for a link between the base station and user equipment and between the base station and the relay node. The relay node uses the same radio access technology for a link between the base station and the relay node and between the relay node and the user equipment. The relay node supports at least a Physical Layer (PHY), a Medium Access Control (MAC) sub-layer and a Radio Link Control (RLC) sub-layer protocol.

A transmitter is for use with multiple transmit antennas and includes a precoder unit configured to precode data for a transmission using a precoding matrix selected from a codebook, wherein the codebook corresponds to the following three transmission properties for an uplink transmission: 1) all precoding elements from the precoding matrix have a same magnitude, 2) each precoding element from the precoding matrix is taken from a set of finite values and 3) there is only one non-zero element in any row of the precoding matrix. The transmitter also includes a transmit unit configured to transmit the precoded data.

This invention is a method and an apparatus to up link transmission of data from a user equipment to a base station for single user multiple input, multiple output. This invention includes receiving at least one codeword, permuting the received codewords, precoding the permuted codewords and transmitting the predecoded codewords on plural antennas. The codewords may be permuted by layer permutation or by codeword permutation.

This invention is a method of downlink, multiuser, multiple input, multiple output communication between a single base station and plural user equipment. Resource buffers are distributed into sub-bands. Each user equipment is assigned to a sub-band with at least one sub-band assigned plural user equipment. The base station transmits user equipment according to assigned sub-bands. A single user equipment may be assigned one sub-band while plural user equipment are assigned to another sub-band. In one embodiment the base station has N transmit antennas. N user equipment is assigned to a first sub-band and less than N user equipment is assigned to a second sub-band. In another embodiment a first second user equipment is assigned a first sub-band and the first and a third user equipment are assigned to a second sub-band.

This invention concerns multiplexing in Long Term Evolution (LTE) and Long Term Evolution-Advanced (LTE-A) in Evolved Universal Terrestrial Radio Access Network (E-UTRAN) wireless telephony. Joint processing down link coordinated multi-point reference signaling includes combining resource signal types at a user equipment, determining conflicts between resource signals of plural user equipment, puncturing resource signals of other cell upon determining conflicts between resource signals of plural user equipment and transmitting non-punctured combined resource signals from a user equipment.

摘要:
This invention is a method for extending the coverage and/or improving the capacity of wireless communication networks comprising inserting a Relay Node (RN) in the Radio Access Network (RAN). The relay node relays the signal between the Base Station node (eNB) and the User Equipment (UE). The relay node is wirelessly connected to the base station. The base station uses the same radio access technology (RAT) for the base station to user equipment link and the base station to relay node link. The relay node uses the same radio access technology for the base station to relay node link and the relay node to user equipment link. The relay node is non-transparent and seen as base station by the user equipment.

This invention is a method of predecoding for joint processing coordinated multi-point transmission. The invention identifies for a particular transmission the cooperating point and the transmit antenna. The invention selects a code by reference to a selected one of a super-cell codebook for each combination of cooperating point and transmit antenna and a multi-cell codebook for each transmit antenna regardless of the cooperating point.
