摘要： Methods and apparatus are disclosed for receiving user data in a wireless communication system (300) that employs coordinated multi-point transmission of the user data from a first cell serving a wireless terminal (635) and a second cell site neighboring the first cell site. In an exemplary system, the first cell site maps control signals (110, 230, 240) and user data to a time-frequency resources (220) according to a first mapping pattern, while the second cell site maps control data (1 10, 230, 240) and traffic data to the time-frequency resources (220) according to a second mapping pattern. An exemplary method comprises extracting (520) user data, according to the first mapping pattern, from time-frequency resources (220) of a first transmission for the wireless terminal (635) transmitted from the first cell site; detecting (540) a control element transmitted by one of the first and second cell sites, the control element indicating that user data associated with the control element is mapped to the time-frequency resources (220) according to the second mapping pattern; and, responsive to said detecting, extracting (550) user data according to the second mapping pattern from time-frequency resources (220) of a second transmission for the wireless terminal (635) transmitted from the second cell site.

摘要： A system, method and node of single-carrier layer shifting for multiple- stream transmission in a network. Per-symbol layer shifting for multiple-stream transmission is implemented using DFTS-OFDM as an access technique. Code word-to-layer mapping is fixed within a DFTS-OFDM symbol and only shifted across consecutive DFTS-OFDM symbols. The method begins by receiving a multiple-stream transmission by a mapping module for transmission. The transmission includes a plurality of subframes and information carrying symbols transmitted on a plurality of layers. A per-symbol layer shifting scheme is then implemented on the transmission where layer shifting is conducted upon each symbol.

摘要： A transmission scheme for spatial multiplexing MIMO systems allows use of SIC at the receiver with a single HARQ process or multiple HARQ processes. Error detection bits are added to an information block to generate and transport block (TDB) for a single HARQ instance having information bits and error detection bits. The transport block is then divided into two or more parts referred to herein as sub-blocks. Each sub-block is encoded according to a different modulation and coding scheme (MCS). The sub-blocks are combined to form two or more codewords for transmission to a receiving station.

摘要： The present invention relates to a method and arrangements in a communication system for Multi User Multiple-Input-Multiple-Output (MU-MIMO) signaling via Multiple-Input-Multiple-Output (MIMO) antennas between a base station and one of a plurality of mobile terminals supporting both Single User and Multi User Multiple- Input-Multiple-Output (SU-MIMO and MU-MIMO) signaling modes. Switching between the modes is supported in the system and the modes have partly shared signaling. SU-MIMO mode signaling which is redundant, i.e. not needed, for MU- MIMO mode signaling is identified. Bits, i.e. data bits, of the identified redundant signaling is re-interpreted or re-defined to comprise signaling information associated with MU-MIMO mode. The signaling information associated with MU-MIMO mode is signaled to the mobile terminal by using the reinterpreted redundant bits.

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： Systems and methods are disclosed for using multiple configuration groups having corresponding configuration identity (CID) parameters to configure a trans-mission channel and a reception channel for a user equipment device in a cellular communication network. In one embodiment, a user equipment device "in a cellular communication network obtains CID values for CID parameters for a number of configuration groups. Each of the configuration groups includes one or more transmission channel or reception channel parameters. For each of the configuration groups, the user equipment device configures the parameters in the configuration group based on the CID value obtained for the CID parameter for the configuration group. In this manner, the transmission channel and the reception channel for the user equipment device are configured based on multiple CID values rather than a single physical layer cell identifier for a cell in which the user equipment device is located.

摘要： A high-power point (110) and one or more low-power points (120) transmit signals associated with the same cell-identifier in a heterogeneous cell deployment. Coverage areas corresponding to the low-power points (120) fall at least partly within the coverage area for the high-power point, so that mobile stations (130) within range of a low-power point are also within range of the high-power point (110). A low-power point (120) measures timing or frequency, or both, of one or more signals received at the low-power point (120) from the high-power point (110), and adjusts the timing or frequency, or both, of a transmission from the low-power point (120) to a mobile station (130), to align the transmission with signals received by the mobile station (130) from the high-power point (110).
