Abstract:
The disclosure provides a network access method and a user equipment (UE) using the same method in an environment of a 5G communication system. In an exemplary embodiment in accordance with the disclosure, the disclosure is directed to a network access method for a UE. The method would include not limited to: receiving a Synchronization Signal/physical broadcast channel Block (SSB) which comprises at least one of a physical broadcast channel (PBCH), a primary synchronization signal (PSS), a secondary synchronization signal (SSS) or mapping information; and determining from the SSB at least one of a SSB candidate number, a SSB index or a SSB pattern.

A method of handling a cell selection for a communication device comprises performing the cell selection in a first one of a normal mode and a coverage enhancement mode, to select a cell; and camping on the cell in a second one of the normal mode and the coverage enhancement mode.
Abstract:
A data transmission method of a device comprises the following steps: transmitting a data to another device; receiving a feedback information from the another device; and when the feedback information indicates a transmission error of the device occurs, determining whether to perform retransmission according to the feedback information.
Abstract:
UE-specific search spaces (UE-SS) for a carrier-aggregated communication system are introduced to decrease the number of blind decoding attempts, decrease downlink control information (DCI) blocking probability, and maintain good blind decoding performance. In the proposed control channel allocation method, the control channel searching method and the communication apparatus thereof, the UE-specific search spaces are extended except control channel element (CCE) aggregation level one. Further, a new CCE aggregation level is created in the UE-specific search spaces. The sum of the number of control channel candidates for all aggregation levels is bounded by the maximum number of PDCCH candidates. In addition, uplink MIMO grant command is just allocated in a pre-configured component carrier or a set of pre-configured component carriers, but uplink MIMO grant command is not allocated in the remaining component carriers.
Abstract:
A method of handling a hybrid automatic repeat request (HARQ) feedback in a subframe for a first communication device in a wireless communication system comprises determining whether the HARQ feedback exists in a physical HARQ indicator channel (PHICH) in a downlink (DL) control region of the subframe transmitted by a network of the wireless communication system according to a first uplink (UL)/DL configuration of the first communication device and a second UL/DL configuration of a second communication device in the wireless communication system communicating with the network; detecting the HARQ feedback in the PHICH of the subframe, if the HARQ feedback exists in the PHICH; and detecting the HARQ feedback in an enhanced PHICH (ePHICH) of the subframe, if the HARQ feedback does not exist in the PHICH.
Abstract:
