The method comprises selecting (210), based on at least one parameter related to transmission of the CSI-only report, a transport block out of two or more available transport blocks, such that the at least one parameter is derivable from an indication of which transport block was selected.

摘要： In a heterogeneous network cell deployment a mobile terminal may need to receive control data transmissions from a macro node at the same time as a pico node is transmitting user data for the mobile terminal, using the same frequency or set of frequencies. This can result in a problematic interference situation. According to several embodiments of the present invention, at least one of two general approaches is used to mitigate the interference situation described above. In a first approach, the pico node's transmission power is reduced in some time intervals, thereby reducing the interference to a level where reception from the macro node is possible. In a second approach, which may be combined with the first approach in some cases, relevant data (e.g. control information) transmitted from the macro node is provided by the pico node, either alone or in combination with the macro node (i.e. simultaneously to the macro node during the same protected transmission time intervals).
摘要翻译：在异构网络小区部署中，移动终端可能需要在微微节点正在使用相同的频率或频率集合为移动终端发送用户数据的同时从宏节点接收控制数据传输。这可能导致有问题的干扰情况。根据本发明的几个实施例，使用两种一般方法中的至少一种来减轻上述干扰情况。在第一种方法中，微微节点的传输功率在一些时间间隔内减小，从而将干扰降低到可能从宏节点接收的水平。在一些可能与第一种方法组合的第二种方法中，从宏节点发送的相关数据（例如，控制信息）由微微节点提供，单独或与宏节点组合（即同时到达宏节点在相同的受保护传输时间间隔期间）。

摘要： A technique for generating a reference signal for use in a communication system in which for reference signal generation multiple base sequences are defined is presented. A method implementation of the technique comprises generating a first reference signal sequence from a first base sequence and a second reference signal sequence from a second base sequence. In a next step, a reference signal is generated that comprises the first reference signal sequence and the second reference signal sequence. The first reference signal sequence occupies a first spectral fragment of the reference signal, and the second reference signal sequence occupies a second spectral fragment of the reference signal. The second spectral fragment and the first spectral fragment do not overlap.

摘要： A reference signal, RS, is generated in a wireless communication system based on a starting position, in the frequency domain, of the RS and a transmission channel bandwidth of the RS. At least one of the starting position of the RS and the bandwidth allocated to a transmission channel for the RS is/are ascertained. A base sequence index, BSI, is then derived by mapping at least one ascertained of the RS starting position and transmission channel bandwidth (12) according to a predefined mapping rule (14) to the BSI (16). The RS is determined based on the derived BSI.

摘要： According to some embodiments, there is provided a base station, system configured to, among other things, (a) detect whether a particular UE is using too much power to transmit uplink data and (b) in response, transmit a message to the UE instructing the UE to detect a power control RS (PCRS) that is intended only for the particular UE. In some embodiments, the PCRS is transmitted such that the power (actual or nominal) of the PCRS as received by the UE is higher than the power of the previous CRS detected by the UE, thereby leading the UE to calculate a lower PL values which ears lead to the UE lowering its output power.

摘要： Techniques are disclosed for signaling a pattern of cyclic shifts and orthogonal cover codes for use by a wireless device (110, 120) 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 p re-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： Downlink control information, DCI, messages used for signaling downlink resource grants are employed for triggering sounding reference signal transmission in the uplink. An index of the uplink component carrier that should be used for the transmission is derived from SIB-2 linking between the downlink component carrier targeted by the downlink DCI message and one of the uplink component carriers configured for the mobile station, when the linking is available. In some cases the downlink component carrier targeted by the downlink DCI message is identified by a carrier identification field in the downlink DCI. Variants of the disclosed techniques involve a default uplink component carrier, which is used in the event that the SIB-2 based allocation is not possible or desired. The default uplink component carrier can be statically defined or semi- statically signaled by Radio Resource Control, RRC, signaling.
