    摘要: In a wireless network that operates according to the Long-Term Evolution Advanced standard, a mobile station determines a number of resource elements to be used for HARQ-ACK (hybrid automatic-repeat-request acknowledgement information) or RI (rank indication) on a MIMO (multiple-input multiple-output) PUSCH (physical uplink shared channel). In an embodiment, the mobile station determines a number O of bits in a payload for HARQ-ACK or RI. When the payload O is within a first range, the mobile station determines a minimum number Qmin of resource elements to be used according to a first equation. When the payload O is within a second range, the mobile station determines the minimum number Qmin of resource elements to be used according to a second equation. The mobile station then determines the number Q′ of resource elements according to Qmin and a third equation.

    摘要: A base station is provided. The base station includes a transmit path circuitry to transmit an indication of whether a subscriber station is configured with precoding matrix indicator/rank indicator (PMI/RI) reporting. The transmit path circuitry sets a pre-coding granularity to multiple physical resource blocks in the frequency domain to perform a same pre-coding over a bundled resource block if the subscriber station is configured with PMI/RI reporting. The bundled resource block includes multiple consecutive physical resource blocks in the frequency domain. The base station also includes a receive path circuitry to receive feedback from the subscriber station.

    摘要: Methods and apparatus for downlink Physical Hybrid Automatic Repeat-reQuest (HARQ) Indicator Channel (PHICH) mapping and channelization in a communication system. First, a base station assigns uplink (UL) physical resource block (PRB) indices to a set of units of user equipment in a cell. Then, for each user equipment, the base station calculates an index triple (KPHICH,0,KPHICH,1,KPHICH,2) for three repetitions of a PHICH signal to be transmitted to the user equipment, with KPHICH, i being a PHICH index indicating a PHICH resource for transmitting the i-th repetition of the PHICH signal to the user equipment, and i=1, 2, 3. When a data packet is received from a unit of user equipment transmitted via at least one physical resource block (PRB) indicated by the at least one PRB index that is assigned to the user equipment, the base station transmits PHICH signals to the user equipment by using the PHICH resources indicated by the PHICH indices assigned to the user equipment.

    摘要: A mobile station is capable of exchanging control information in a communication system. A mobile station transceiver receives downlink control information on an Enhanced Physical Downlink Control Channel (EPDCCH) comprising a Enhanced Control Channel Elements (ECCE). A mobile station controller identifies a first resource for uplink control information based on the first ECCE of the at least one ECCE, a resource offset configured for the EPDCCH, and ACK/NACK resource offset on the EPDCCH, when the EPDCCH is distributed transmission, and also identifies a second resource for uplink control information based on the first ECCE of the at least one ECCE, a resource offset configured for the EPDCCH, ACK/NACK resource offset on the EPDCCH and C-RNTI, if the EPDCCH is localized transmission. The transceiver also transmits the uplink control information on the first resource or the second resource according to whether the EPDCCH is distributed transmission or localized transmission.

    摘要: A base station includes a transmit path circuitry to transmit an uplink grant in a DCI format to a subscriber station. The base station also includes a receive path circuitry to receive only UCI on a PUSCH from a subscriber station when the uplink grant includes a MCS of an enabled transport block (TB) with a value of 29, or a redundancy version of the PUSCH with a value of 1; a CSI request field with a non-zero value; and a total number of physical resource blocks allocated for the subscriber station, NPRB, with a value less than or equal to a threshold number of physical resource blocks, TPRB. TPRB is based at least partly upon one of a total number of CSI information bits to be transmitted on the PUSCH, Ntotal, and a number of DL CCs reported in a current CSI reporting, NCCs.

    摘要: 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.

    摘要: A subscriber station is provided. The subscriber station includes a transmit path circuitry to transmit uplink control information (UCI) in a subframe comprising one or more resource blocks, each resource block comprising S SC-FDM symbols. Each of the S symbols comprises N virtual subcarriers, and each subcarrier of each symbol comprises a resource element. The subscriber station also includes a UCI symbol allocator to allocate a first vector sequence of HARQ-ACK bits to a control region of each of four symbols of a resource block, the control region allocated for HARQ-ACK bits. The UCI symbol allocator also allocates a second vector sequence of HARQ-ACK bits to a control region of a fifth symbol of the resource block when a condition is met. The control region of the fifth symbol can be allocated for rank information (RI) bits.
