Embodiment 1

[0099] Preferred embodiment one (eNB side):

[0100] figure 2 It is a flow chart of parameter configuration during dynamic adjustment of uplink and downlink subframe ratios according to preferred embodiment 1 of the present invention. Such as figure 2 As shown, the process may include the following processing steps:

[0101] S202: The eNB broadcasts a system message in the cell, wherein the configuration ratio of uplink and downlink subframes carried in the system message is ratio 0 (the ratio index is 0, and the uplink subframe corresponding to index 0 can be found from the above Table 1 , downlink subframe ratio).

[0102] S204: The eNB sends an RRC reconfiguration message to the UE, wherein the RRC reconfiguration message contains 4 sets of configuration information, namely configuration 1, configuration 2, configuration 3 and configuration 4; for configurations 2, 3 and 4, signaling can be used Explicitly indicate that it is bound with uplink and downlink subframe ra...

Abstract

Disclosed are an information delivery and processing method and apparatus. The method comprises: sending an RRC layer message to a terminal side device, information carried in the RRC layer message comprising multiple sets of configuration information and each set of the configuration information being bound to one or more ratios of uplink subframes to downlink subframes; and instructing, by using MAC layer signaling or physical layer signaling, the terminal side device to update the current ratio of the uplink subframes to the downlink subframes, and determining that the terminal side device continues to use the configuration information bound to the updated ratio of the uplink subframes to the downlink subframes. According to the technical solutions provided in the present invention, in a case in which no extra RRC signaling load is added in a system enabling dynamitic adjustment of uplink subframes and downlink subframes, different parameters can be configured for each of potential ratios of the uplink subframes to the downlink subframes, and the performance of a UE in different ratios of the uplink subframes to the downlink subframes is effectively improved, thereby improving the user experience.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for issuing and processing configuration information. Background technique [0002] Currently, in a Long Term Evolution (LTE for short) system, the LTE Time Division Duplex (TDD) adopts a frame type 2 (Frame structure type2). In frame type 2, the length of each radio frame is 10ms, which includes: 10 subframes with a length of 1ms, and each subframe can be configured as uplink, downlink or used as a special subframe as required. Table 1 shows the ratio relationship between uplink and downlink subframes defined in the TS36.211 protocol. As shown in Table 1: [0003] Table 1 [0004] [0005] It can be seen from Table 1 that seven types (configurations 0 to 6) of different uplink and downlink subframe configurations are defined in the current protocol. In the early LTE system, the ratio of uplink and downlink subframes used by each cell is statically con...
