    摘要: Techniques are provided for synchronized radio link control (RLC) and/or media access control (MAC). For example, there is provided a method that involves generating an RLC protocol data unit (PDU) according to a segmentation protocol for maximizing RLC PDU size while allowing the RLC PDU to fit into a defined MAC transport block, the RLC PDU comprising at least one RLC service data unit (SDU) or RLC SDU segment. The method may involve determining a PDU data size for each given RLC SDU. The method may further involve (a) attaching a given RLC SDU to the RLC PDU and (b) delivering the RLC PDU to a lower layer, in response to a SDU data size for the given RLC SDU exceeding a defined size limit.

    摘要: Methods and apparatuses are provided for determining cyclic shift (CS) values and/or orthogonal cover codes (OCC) for a plurality of demodulation reference signals (DM-RS) transmitted over multiple layers in multiple-input multiple-output (MIMO) communications. A CS index can be received from a base station in downlink control information (DCI) or similar signaling. Based at least in part on the CS index, CS values for the plurality of DM-RSs can be determined. In addition, OCC can be explicitly signaled or similarly determined from the CS index and/or a configured CS value received from a higher layer. In addition, controlling assignment of CS indices and/or OCC can facilitate providing orthogonality for communications from paired devices in multiuser MIMO.

    摘要: Techniques for transmitting data from multiple transmit antennas using space orthogonal resource transmit diversity (SORTD) are described. For the SORTD scheme, a different orthogonal resource may be assigned to each transmit antenna. Data may be sent from the multiple transmit antennas using multiple orthogonal resources. In one design, a UE may process at least one information bit (e.g., with joint or independent coding) to obtain first and second sets of at least one modulation symbol. The UE may process the first set of modulation symbol(s) for transmission from the first transmit antenna using a first orthogonal resource. The UE may process the second set of modulation symbol(s) for transmission from the second transmit antenna using a second orthogonal resource. Each orthogonal resource may include a different reference signal sequence or a different set of reference signal sequence and orthogonal sequence.
