摘要： A radio resource allocation method in a communication node is disclosed. The method comprises determining (424) that a first time reference or a first communication using a first component carrier has a time shift compared to a second time reference of a second communication using a second component carrier. The method further comprises determining (426) a duration of a communication sub-frame based on the time shift, and scheduling (428) the determined communication sub-frame on a first component carrier to a first communication device. The determined frame duration is equal to the time shift or equal to the normal sub-frame length minus the time shift so as to avoid any overlap or interference. Corresponding computer program product, arrangement, communication node and first communication device are also disclosed.

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”.

摘要： According to the teachings herein, an LTE or other wireless communication network provides for independent control of SRS transmissions by a UE or other wireless device. The network advantageously sends DCI messages for SRS power control using a modified format 3/3A, where the message length conforms to that used for conventional format 3/3A messages but where the message is masked using a distinct RNTI. Correspondingly, the wireless device is configured to recognize from the distinct RNTI that the received TPC commands are targeted to controlling the uplink transmit power used by the wireless device for SRS transmissions.

摘要： A method of operating a first wireless communication device to perform D2D discovery includes obtaining multiple discovery message detection results, and determining a D2D discovery status of a second wireless communication device based on the multiple discovery message detection results. Using multiple discovery message detection results to determine the D2D discovery status of the second wireless communication device significantly increases the reliability of D2D discovery, thereby increasing the likelihood that a device available for D2D communication will be detected, while reducing the likelihood of false detections.
