摘要:
A base station includes a transmit path circuitry to transmit DL grant, data streams, and a control signal to configure a number of uplink transmit antenna ports PUCCH to a subscriber station. The base station also includes a receive path circuitry to receive ACK/NACK modulation in response to the data streams. If the subscriber station is configured to transmit ACK/NACK using one uplink transmit antenna port and channel selection with PUCCH format 1B, a modulation symbol is transmitted on one (PUCCH) i determined based at least partly upon a channel selection mapping table. If the subscriber station is configured to transmit ACK/NACK using two uplink transmit antenna ports and channel selection with PUCCH format 1B, the ACK/NACK modulation symbol is transmitted on two PUCCHs.

A base station for use in a wireless network capable of communicating with a plurality of mobile stations. The base station transmits to a first mobile station downlink subframes of OFDM symbols. Each downlink subframe comprises a plurality of resource blocks and is associated with a subframe (SF) type that is determined according to whether or not a PDSCH region of a resource block in a downlink subframe includes at least one of: 1) a cell-specific reference signal (CRS) resource element and 2) a channel-state-information reference signal (CSI-RS) resource element. The base station receives from the first mobile station at least one of COI, PMI, modulation scheme, and transport block size and interprets the received at least one of COI, PMI, modulation scheme, and transport block size according to a default SF type used by the first mobile station to determine the at least one of COI, PMI, modulation scheme, and transport block size.

A base station includes a reference signal sequence generator configured to generate a reference signal sequence for a reference signal for each of n antenna ports using one initialization seed with n being a positive integer. The initialization seed is defined as: cinit=(└ns/2┘+1)·(2NIDcell+1)·216+NIDgroup, where ns is a first slot number in a subframe, NIDcell is a cell identifier of the base station, and NIDgroup is a group identifier. The base station also includes a transmit path circuitry configured to transmit a downlink grant and the reference signal. In some embodiments, the group identifier NIDgroup is a one-bit group identifier dynamically indicated in a codepoint in the downlink grant transmitted by the base station.

A base station includes a transmit path circuitry to scramble CRC bits of a DCI format using a C-RNTI for dynamic scheduling, and scramble the CRC bits of the DCI format using an SPS C-RNTI for semi-persistent scheduling. If C-RNTI is used, the circuitry generates a downlink transmission grant using the DCI format being a fallback format to indicate a transmit diversity transmission scheme or a single-layer beamforming scheme, and uses the DCI format being a dual-layer beamforming format to indicate a dual-DRS port transmission scheme or a single-DRS port transmission scheme.If SPS C-RNTI is used, the circuitry generates a downlink transmission grant using the DCI format being the fallback format to indicate a single-DRS port transmission scheme, and uses the DCI format being the dual-layer beamforming format to indicate a dual-DRS port transmission scheme or a single-DRS port transmission scheme.

A system and method for interference mitigation. The system and method includes a number of base stations configured to coordinate with each other to perform a joint transmission to one or more subscriber stations. The base stations allocate a portion of a frequency band for the joint transmission and jointly schedule the joint transmission. Further, the base stations are configured to select a common codebook or separate codebooks to perform the joint transmission. Thereafter, the joint transmission is performed wherein the one or more subscribers stations substantially simultaneously receive the joint transmission from each of the base stations.
