    摘要: A downlink subframe on a single downlink carrier supports physical layer acknowledgment signaling for multiple physical uplink shared channel (PUSCH) transmissions. The physical layer acknowledgement signaling may take the form of physical hybrid ARQ indicator channel (PHICH) signaling. A base unit reserves resource elements groups (REGs) for default PHICH signaling of default PUSCH transmissions. The base unit reserves control channel elements (CCEs) for physical downlink control channel (PDCCH) signaling. A CCE contains multiple interleaved REGs. The base unit takes any unreserved CCEs and maps those CCEs for physical layer acknowledgement signaling of additional PUSCH transmissions.

    摘要: A wireless communication terminal receives a first set of pilot signal resource elements and control information in spatial layers in a first resource block in a subframe and a second set of pilot signal resource elements and data in spatial layers in a second resource block in the subframe, wherein the first and second resource blocks span a set of time symbols in a sub-frame, the first resource blocks span a first set of frequency carriers in the sub-frame, and the second resource blocks span a second set of frequency carriers in the sub-frame. The terminal decodes the spatial layers in which the control information is received using the first set of pilot signal resource elements. The terminal also decodes the spatial layers in which the data are received in the second resource block using the second set of pilot signal resource elements.

    摘要: A wireless user terminal includes a controller communicably coupled to a transceiver. The controller is configured to determine scheduling grant information and additional scheduling grant information from a channel encoded scheduling grant received at the transceiver, wherein the channel encoded scheduling grant includes encoded parity bits combined with the scheduling grant information and the encoded parity bits include the additional scheduling grant information exclusive OR-ed with parity bits obtained from the scheduling grant information.

    摘要: A method and apparatus for performing resource allocation with lower required overhead is provided herein. Resource allocations for data transmissions are chosen in such a way as to provide channel quality information for various parts of the channel bandwidth (frequency selective channel quality information), such as allocating two different resource blocks (on different sets of subcarriers) to a mobile unit for two different transmissions. These data transmissions are used to estimate frequency selective channel quality information, thereby eliminating or greatly reducing the need for channel sounding with a broadband pilot. As a result, the overhead on the uplink of the communication system may be significantly reduced.

    摘要: A method and apparatus for generating a single statically defined downlink reference MCS table consisting of transport block sizes (TBSs) computed for 29 MCSs for each of j PRBs where j=1, . . . , NRBDL. Three entries of the MCS table are reserved for implicit modulation order signaling (e.g. in the downlink) or implicit redundancy version signaling (e.g. in the uplink). Each MCS entry in the table is populated by a TBS and the table entries are accessed based on a 5-bit MCS index and resource allocation information, indicating the number of PRBs is signaled via a scheduling message which may be a grant or assignment message. A grant or assignment message may further include a 5-bit MCS field for each transport block which, along with the resource allocation information, enables the UE to determine the scheduled TBS.
