Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] In the LTE system and its evolved system, multiple PDCCHs can be transmitted simultaneously in one subframe, and one PDCCH is composed of n consecutive CCEs. Four different types of PDCCHs are supported in LTE, and their formats are 0, 1, 2, and 3; the corresponding aggregation levels are 1, 2, 4, and 8; where the aggregation level represents the consecutive CCEs occupied by a PDCCH number.

[0028] According to different scopes, t...

Abstract

The invention discloses an RNTI distribution method and device. In the method, a base station selects the RNTI for user equipment, and the base station determines the starting position of the search space special for the UE based on the selected RNTI, if the starting position of the search space special for the UE is the same as the starting position of the common search space, the base station re-selects the RNTI for the user equipment, and if the starting position of the search space special for the UE is different from the starting position of the common search space, the selected RNTI is distributed to the user equipment. Before the RNTI is distributed to the user equipment, whether the starting position of the search space special for the UE is the same as the starting position of the common search space is determined in advance, so that the problem that the uplink scheduling generated when the PDCCH resources to be scheduled by some of the sub-frames are greater than two is insufficient can be prevented, and the user experience feeling can be improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an RNTI allocation method and device. Background technique [0002] In LTE (Long Term Evolution, Long Term Evolution), uplink and downlink resource scheduling information is carried by a PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel). PDCCH mainly carries PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) and PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel), and the PDCCH information of different terminals passes its corresponding RNTI (Radio Network Temporary Identity, wireless network temporary identification ) information distinction. [0003] Multiple PDCCHs can be transmitted simultaneously in one subframe, and one PDCCH is composed of n consecutive CCEs (Control Channel Elements, Control Channel Elements), and the aggregation level is used to indicate the number of CCEs occupied by one...
