摘要： Techniques are disclosed for signaling a pattern of cyclic shifts and orthogonal cover codes for use by a wireless device in multi-layer transmissions. In one example method, a signal includes B bits for identifying a reference signal is received, wherein each of several available reference signals is defined by a cyclic shift and an orthogonal cover code. The B bits are used to identify the cyclic shift and orthogonal cover code according to pre-determined tables that map each value of the B bits to a pattern of cyclic shift and orthogonal cover code combinations for a multi-layer transmission scheme. The patterns for the multi-layer transmission scheme include first and second patterns based on the same cyclic shifts, but where some, but not all, of the cyclic shifts in the first pattern are associated with the same corresponding orthogonal cover codes in the second pattern.

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： Some embodiments provide a method for channel estimation in a wireless device. According to the method, the wireless device obtains an indication that a set of antenna ports, or antenna port types, share at least one channel property. The wireless device then estimates one or more of the shared channel properties based at least on a first reference signal received from a first antenna port included in the set, or having a type corresponding to one of the types in the set. Furthermore, the wireless device performs channel estimation based on a second reference signal received from a second antenna port included in the set, or having a type corresponding to one of the types in the set, wherein the channel estimation is performed using at least the estimated channel properties.
