Problems solved by technology

[0007] However, in order to realize the real-time dynamic adjustment of the carrier, Fast Carrier Selection (FCS) needs to be achieved when the carrier is activated or deactivated. In the prior art, the activation or deactivation status of the carrier is indicated to the user through the MAC CE equipment, because the transmission delay of MAC signaling is difficult to meet the requirements of FCS; and the activation or deactivation status of its carrier is indicated to each user equipment one by one, occupying channel resources, which will increase the network load and further increase the activation of the carrier Or deactivation delay, carrier activation or deactivation state indication efficiency is low

Embodiment 1

[0469] An embodiment of the present invention provides a carrier state indication method, which can be applied to a base station, such as figure 1 As shown, the carrier state indication method includes:

[0470] S101. The base station determines a carrier state of a carrier, where the carrier state is an activated state or a deactivated state.

[0471] Specifically, the base station may determine the carrier state of at least one carrier according to channel state information (CSI Channel State Information, CSI) of the user equipment, load state of the cell, indication of other base stations, and the like. Wherein, the CSI may include at least: a channel quality indicator (Channel Quality Indicator, CQI), a precoding matrix indicator (Precording Matrix Indicator, PMI), and a rank indicator RI.

[0472] It should be noted that the method for the base station to determine the carrier state of at least one carrier includes but is not limited to the methods listed in the embodime...

Embodiment 2

[0483] An embodiment of the present invention provides a carrier state indication method, which can be applied to a base station, such as figure 2 As shown, the carrier state indication method includes:

[0484] S201. The base station determines a carrier state of a carrier, where the carrier state is an activated state or a deactivated state.

[0485] It should be noted that, the specific method for the base station to determine the carrier state of the carrier in this embodiment is similar to the method for the base station to determine the carrier state of the carrier in Embodiment 1, which will not be repeated here in this embodiment.

[0486] S202. The base station indicates the first carrier information to the user equipment through the physical broadcast channel or the physical downlink shared channel indicated by the downlink control information.

[0487] Wherein, the first carrier information includes a carrier state of the carrier, and the first carrier information...

Embodiment 3

[0497] The embodiment of the present invention also provides a carrier state indication method, which can be applied to user equipment, such as image 3 As shown, the carrier state indication method includes:

[0498] S301. The user equipment receives a downlink physical control channel sent by a base station. The downlink physical control channel includes first carrier information, and the first carrier information includes a carrier state of a carrier, where the carrier state is an activated state or a deactivated state.

[0499] It should be noted that the carrier state of the carrier included in the first carrier information includes: the carrier state of the carrier on the base station and / or the carrier state of the carrier on other base stations.

[0500] Wherein, for other base stations in the embodiment of the present invention, reference may be made to the relevant description in Embodiment 1 of the present invention, and details will not be repeated here in the embo...

Abstract

Disclosed are a carrier state indication method and device, relating to the field of telecommunications, reducing the delay in indicating that a carrier is in an activated or a deactivated state, and improving the efficiency of indicating that a carrier is in an activated or a deactivated state. The specific solution is: a base station determining the carrier state of a carrier, said state being an activated state or a deactivated state; indicating a first carrier information to a user device via a physical downlink control channel, said information comprising the carrier state of the carrier, and being used to allow the user device to communicate on the carrier, based on the state thereof. The present invention is applicable during carrier switching.

Description

[0001] This application claims the priority of submitting to the Chinese Patent Office on July 1, 2013, the application number is PCT / CN2013 / 078588, and the title of the invention is "a carrier state indication method and device", the entire content of which is incorporated in this application by reference middle. technical field [0002] The present invention relates to the communication field, in particular to a carrier state indication method and equipment. Background technique [0003] Carrier Aggregation (CA, Carrier Aggregation) technology introduced in the 3rd Generation Partnership Project (The 3rd Generation Partnership Project, 3GPP), the user equipment (User Equipment, UE) can use multiple component carriers (Component Carrier, CC) at the same time Uplink and / or downlink communication can improve the transmission rate and service quality of the network, and guarantee the rate of general users without greatly increasing the configured bandwidth, while providing hig...
