    Abstract: A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations. The transmission from the secondary to primary node in a wireless network is obtained using an orthogonal covering sequence and a second sequence. Embodiments of the present invention mitigate interference by calculating a first orthogonal covering (OC) index and a second OC Index from an indicator received from a serving base station (NodeB). A first index n1 is derived and a second index n2 is derived using the first index n1. A first orthogonal covering (OC) index and a first cyclic shift (CS) is determined using the derived index n1. A second OC and a second CS is derived using the derived index n2. A first slot of a subframe is generated using the OC indexed by the first OC index and the first CS and a second slot of the subframe is generated using the OC indexed by the second OC index and the second CS.

    Abstract: 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.

    Abstract: In ACK/NAK responses with repetition, the ACK/NAK response from the user equipment to a Physical Downlink Shared CHannel (PDSCH) transmission is repeated in consecutive frames a predetermined number of frames following receipt. This repeat ACK/NAK causes a problem when a PSCCH transmission directed to the same user equipment occurs in consecutive subframes. In a first embodiment, the first ACK/NAK response repeats preempting any ACK/NAK response to the later PDSCH transmission. In a second embodiment, the first ACK/NAK response does not repeat and the ACK/NAK response to the later PDSCH transmission occurs.

    Abstract translation: 在具有重复的ACK / NAK响应中，从用户设备到物理下行链路共享信道（PDSCH）传输的ACK / NAK响应在接收后以预定数量的帧在连续帧中重复。 当连续的子帧中发生指向同一用户设备的PSCCH传输时，这种重复ACK / NAK引起问题。 在第一实施例中，第一ACK / NAK响应重复抢占对稍后的PDSCH传输的任何ACK / NAK响应。 在第二实施例中，第一ACK / NAK响应不重复，并且发生对稍后的PDSCH传输的ACK / NAK响应。

    Abstract: A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations on an uplink channel in a wireless network. A scheme for mapping between logical uplink control channel (PUCCH) resource blocks (RBs) and physical RBs (PRBs) used by PUCCH is described. A logical uplink control resource block index nLRB is derived by the secondary node in response to information from the primary node. The secondary node then maps the logical uplink control resource block index nLRB to a first uplink physical resource block index nPRB,1 of a plurality of uplink physical resource blocks, wherein nPRB,1=nLRB/2 if nLRB is even and nPRB,1=NPRB−ceil(nLRB/2) if nLRB is odd; wherein NPRB is the total number of the plurality of uplink physical resource blocks; and wherein ceil denotes the ceiling operation. The secondary node then transmits an uplink control information in a subframe using one of the plurality of uplink physical resource blocks indexed by nPRB,1.
