    摘要: Embodiments of present invention provide a linear-drive pluggable optics (LPO) transceiver. The LPO transceiver includes a receiver path, which includes a receiver optical subassembly (ROSA) converting an input optical signal into an ingress electrical signal; and a linear transimpedance amplifier (TIA) with adjustable frequency transfer function (AFTF), the ingress electrical signal passing through the linear TIA to a host.

    摘要: A method of notifying resource allocation for Demodulation Reference Signal (DMRS) is provided. A base station notifies to a user equipment a power offset value between an average EPRE value for data symbols and an average EPRE value for the DMRS at each layer in a semi-static or static manner. Also, the base station dynamically notifies to the user equipment a current channel rank or a current DMRS distribution pattern for the user equipment. The user equipment determines an allocated DMRS antenna port based on a correspondence between the received channel rank and an allocation of DMRS antenna port, thereby obtaining resource allocation information for the DMRS. The signaling overhead for power allocation in the system can be reduced, the efficiency of power amplifier can be improved and the flexibility of system scheduling can be increased. A method of notifying antenna port resource allocation for DMRS is also provided.

    摘要: A method of resource allocation for Channel State Information (CSI) feedback is provided, which comprises the following steps of: configuring a downlink transmission approach and a feedback mode for each User Equipment (UE); allocating feedback resources required for CSI feedback by each UE based on the configured downlink transmission approach and feedback mode, such that different types underlying different feedback modes for a single UE will not collide with each other within one sub-frame; and notifying each UE of the corresponding configured downlink transmission approach and feedback mode and allocated feedback resources. Further, a method of Channel State Information (CSI) feedback is provided, which comprises the following steps of: feeding downlink CSI back to a base station (BS) based on a downlink transmission approach and a feedback mode configured by the BS; and solving, when different types underlying different feedback modes collide with each other within one sub-frame, the collision based on a collision solution rule.

    摘要: The present invention provides a method and a coder for jointly coding Pre-coding Matrix Index #1 (W1) and Rank Index (RI) for channel state information feedback of a double codebook precoding frame. In the present invention, it is determined whether Rank Index RI is more than 2; if the RI is no more than 2, a first half branch of a coding binary tree is used to represent joint coding of the RI and W1 when RI=1 and RI=2; if the RI is more than 2, a second half branch of the coding binary tree is used to represent remaining separate codings and/or joint codings when the RI is more than 2; and processing results of the above coding steps are output. The present invention may be applied to an equal-length coding or an unequal-length coding. The present invention has advantages such as easy implementation, lower signaling overhead etc., and may be suitable for an LTE-A/4G cellular communication system and a future 5G cellular communication system.
