摘要： Techniques for facilitating and performing frequency-offset estimation are disclosed. The disclosed techniques include methods and apparatus for maintaining phase coherence among reference symbols on different transmission-time intervals (TTI) for an accurate estimation of frequency offset. Corresponding techniques utilize channel estimation or measurements of channel-related parameters based on multiple reference symbols belonging to different TTIs. An example method in a radio transceiver for facilitating frequency offset estimation at a remote receiver begins with determining that phase coherence between reference symbol transmissions in a first TTI and a second TTI is required. The radio transceiver selectively maintains phase coherence between reference symbol transmissions in the first and second TTIs, in response to said determining. The radio transceiver then transmits during at least part of a third TTI, following the second TTI, without maintaining phase coherence to the reference symbol transmissions in the first and second TTIs.

摘要： Orthogonality in cyclic shift (CS) and orthogonal cover code (OCC) selection for DMRS in MIMO is improved by new nDMRS to nDMRS(2) mapping patterns. Values in the mapping tables are arranged in sets, with minimum CS separation between the values in each set. Additionally, the semi-static nDMRS is independently configurable for each UL component carrier (CC) in the case of cross-CC scheduling in carrier aggregation, and the PHICH allocation formula that defines the allocation of the PHICH process relative to the kth codeword (CW) on the cth UL CC is a function of both the CS index nDMRS,k,c(2) that is dynamically assigned to a certain layer of the considered CW and the semi-static CS offset nDMRS,c(1) for the cth CC.

摘要： According to one aspect of the teachings herein, a set of rules for transmitting Downlink Control Information (DCI) messages containing Transmit Power Control (TPC) commands is known to a wireless communication network (10) and to any number of wireless devices (20) supported by network (10). A device (20) receiving a given TPC DCI message knows the uplink channel(s) to which the received TPC command(s) are to be applied based on interpreting the given TPC DCI message according to the known rules. The rules may be defined as internal within the DCI format, such as bits, states or code points. Additionally, or alternatively, the rules may be defined according to external attributes for DCI message transmission, such as whether the DCI message is transmitted on a Physical Downlink Control Channel, “PDCCH” or on an enhanced PDCCH, “ePDCCH”.
