Problems solved by technology

If different beam scanning timings are used for different signals or channels, then there will be many beam scanning timings, resulting in the need to design a large number of downlink symbols in the system, which increases the performance of Hybrid Automatic Repeat reQuest (HARQ) feedback. delay, which increases the complexity of system design

Embodiment Construction

[0045] As mentioned in the background art, how to design a common control channel to achieve better resource utilization is an urgent problem to be solved.

[0046] In the embodiment of the present invention, by configuring the common control channel and the primary synchronization signal and / or secondary synchronization signal to perform frequency division multiplexing, the common control channel and the primary synchronization signal and / or secondary synchronization signal can be sent on the same symbol (or time resource). The synchronization signal achieves better resource utilization; furthermore, it can reduce the timing of beam scanning, reduce the delay of HARQ feedback, and reduce the complexity of system design.

[0047] Furthermore, the technical solution of the present invention implements frequency division multiplexing or time division multiplexing by configuring common control messages and synchronization signal blocks, so as to realize the flexibility of public c...

Abstract

A method and device for configuring and receiving a common control channel, the method for configuring the common control channel includes: configuring the common control channel and a primary synchronization signal and / or a secondary synchronization signal in a user equipment in a frequency division multiplexing manner In the subbands; using the configured resources to send the common control channel. The technical solution of the present invention can improve resource utilization by configuring the common control channel.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a common control channel configuration and reception method and device. Background technique [0002] In the fifth-generation mobile communication technology (5th-Generation, 5G) system, the primary synchronization signal (Primary Synchronization Signal, PSS), the secondary synchronization signal (Secondary Synchronization Signal, SSS) and the physical broadcast channel (Physical Broadcast Channel, PBCH) are in the same Synchronization Signal block (Synchronization Signal block, SS-block). Each synchronization signal block can be regarded as a beam (analog domain) resource in a beamsweeping process. Multiple sync signal blocks form a sync signal burst (SS-burst). The synchronization signal burst can be regarded as a relatively concentrated piece of resource including multiple beams. Multiple synchronization signal bursts form a synchronization signal burst set (...
