Embodiment 1

[0145]Embodiment 1 of the present invention provides a method for obtaining a set of control resources. In this method, a network device determines at least one piece of configuration information, the at least one piece of configuration information includes a first time-domain resource location, and the first time-domain resource The location is unavailable for control information transmission; the network device sends at least one indication information to the terminal device, and the at least one indication information is used to indicate the at least one configuration information; the network device obtains the at least one configuration information according to the at least one configuration information A second control resource set; the network device sends the control information on the second control resource set. The terminal device receives at least one indication information from the network device, where the at least one indication information is used to indicate a f...

Embodiment 2

[0242] Embodiment 2 of the present invention is further described in detail below.

[0243] Embodiment 2 of the present invention provides a method for obtaining a set of control resources, as follows Figure 7 A specific implementation manner of the method for obtaining a control resource set in Embodiment 2 of the present invention will be described. What needs to be explained here is that Embodiment 2 of the present invention is applied to the same scenario as Embodiment 1 of the present invention, and the difference is that the time-frequency position of the control resource set in Embodiment 2 is not changed by its resource position in the time domain. Effects of transport unavailability. Even if the network device determines the first time-domain resource location and at least one indication information as in Embodiment 1 of the present invention, the control information is still transmitted on the first set of control resources. For the terminal device, according to t...

Abstract

The application relates to the field of wireless communication, and provides a method for acquiring control resource sets. The method comprises the following steps that: a terminal device receives atleast one piece of indication information from a network device, wherein at least one piece of indication information is used to indicate a first time domain resource location, and the first time domain resource location is unavailable for control information transmission; the terminal device acquires a second control resource set according to at least one piece of indication information; and theterminal device detects the control information on the second control resource set. The method reduces the signaling overhead caused by the reconfiguration for the control resource sets by the high layer signaling, and reduces the control information detection delay.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to the configuration of control resource sets in a wireless communication system. Background technique [0002] In an existing long term evolution (Long Term Evolution, LTE) system, control channels include two types: a physical downlink control channel (Physical Downlink Control Channel, PDCCH) and an enhanced physical downlink control channel (Enhanced Physical Downlink Control Channel, EPDCCH). In the time domain, the time-frequency resource area where the PDCCH is located is located in the first 0-3 Orthogonal Frequency Division Multiplexing (OFDM) symbols of a subframe, and the time-frequency resource area where the EPDCCH is located is within a subframe. All or part of the downlink OFDM symbols other than the PDCCH; in the frequency domain, the time-frequency region where the PDCCH is located occupies the entire system bandwidth, and the time-frequency region where the EP...
