摘要:
Within a wireless network, feedback information from user equipment (UE) to a control node (eNodeB) is necessary to support various functions. A UE receives an allocation from the eNodeB comprising a plurality of periodic transmission instances for a channel quality indicator (CQI) and a schedule comprising a plurality of periodic transmission instances for a rank indicator (RI), wherein the CQI comprises RI and other CQI fields. The UE then transmits an RI without transmitting the other CQI fields in a transmission instance allocated for both RI and other CQI fields.

Within a wireless network, feedback information from one node to another node is necessary to support various functions. The first node receives an allocation of resources for data transmission. The first node generates cyclic redundancy check (CRC) bits for a selected feedback control information type and encodes the selected feedback information and the CRC bits. The encoding of the feedback information and the CRC bits is adaptive based the amount of allocated resources. The encoded feedback information and CRC bits are then transmitted to the other node using a subset of the allocated resources on the physical shared channel that is normally used only for data transmissions.

For transmission of a block of control information within a wireless network, the control information is interleaved to form an ordered set of control bits, wherein more important information bits of the control information are placed into a first portion of the ordered set of control bits, with less important information bits of the control information placed into a second portion of the ordered set of controls bits. The ordered set of control bits is encoded to form an encoded block of data. The encoded block of data is transmitted to a serving base station, wherein bits from the first portion of the ordered set of control bits will statistically have a lower bit error rate (BER) than bits from the second portion of the ordered set of control bits during transmission.

Transmission with multiple antennas in a wireless network is performed by selecting between adaptive precoding and fixed precoding based on a selection criterion. Transmission using spatial multiplexing with adaptive precoding is performed if the selection criterion is fulfilled. Transmission using spatial multiplexing with fixed preceding is performed if the selection criterion is unfulfilled.

摘要:
A transmission of information within a wireless network may include a first and second type of feedback information, wherein the second type of feedback information is derived based on the first type of feedback information. The first type of feedback information is embedded in a configured frame every T1 frames. The second type of feedback is embedded in a configured frame every T2 frames, wherein T1 is greater than or equal to T2. A sequence of frames is transmitted from one node in the network to a second node on an uplink control channel.

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.
摘要:
Transmission with multiple antennas in a wireless network is performed by transmitting a plurality of reference sequences (RS) from a UE. A first RS s1[k] is produced using a first cyclic shift and a base sequence s0[k], wherein k={1, 2 . . . K} is an element index. A second RS s2[k] is produced using a second cyclic shift and s0[k]. A first symbol sequence x1[k] is produced using at least s1[k] and s2[k], for at least one k. A second symbol sequence x2[k] is produced using at least s1[k] and s2[k], for at least one k. x1[k] is transmitted using a first transmit antenna and x2[k] is transmitted using a second transmit antenna.
