Problems solved by technology

However, as the number of users increases, the communication load concentrated on one PRB will gradually increase, causing service congestion. At the same time, the increased communication load will also limit the flexibility of scheduling and bring greater scheduling delay.

Embodiment 1

[0189] image 3 is a signaling flowchart of an information receiving method shown in an exemplary embodiment of the present application, as shown in image 3 As shown, the method includes:

[0190] In step S301, the base station determines the set of PRBs used to transmit the scheduled PDSCH of the current PDCCH.

[0191] The set of PRBs used to transmit the scheduled PDSCH of the current PDCCH may be determined according to the generated second configuration information, or the set of PRBs may be determined according to a preset rule.

[0192] In addition, optionally, after the PRB set is determined according to the generated second configuration information, the second configuration information may be sent to the UE through high layer signaling.

[0193] In step S302, the base station sends the current PDCCH to the UE through the current PRB, and indicates the PRB used to transmit the scheduled PDSCH in the PRB set through downlink control information (DCI) in the current ...

Embodiment 2

[0211] Figure 4 is a signaling flow chart of another information receiving method shown in an exemplary embodiment of the present application, such as Figure 4 As shown, the method includes:

[0212] In step S401, the base station determines a PRB set for transmitting a PDCCH and its scheduled PDSCH starting from the time point corresponding to the current PDCCH that exceeds a preset duration.

[0213] Wherein, the PRB set used to transmit the PDCCH and its scheduled PDSCH longer than the preset duration starting from the time point corresponding to the current PDCCH can be determined according to the generated third configuration information, or can be determined according to the preset rule. The time point corresponding to the PDCCH is the PDCCH whose starting point exceeds the preset duration and the PRB set for scheduling the PDSCH.

[0214] In addition, optionally, after the PRB set is determined according to the generated third configuration information, the third conf...

[0230] Figure 5 is a signaling flow chart of another information receiving method shown in an exemplary embodiment of the present application, such as Figure 5 As shown, the method includes:

[0231] In step S501, the base station determines, based on the generated first configuration information, for repeated transmission of the PDCCH whose time point corresponding to the current PDCCH exceeds a preset duration and the PRB for scheduling the PDSCH and the repeated transmission of the corresponding channel on each PRB frequency.

[0232] Wherein, the base station may determine the PRB used for repeated transmission of the corresponding channel according to the generated first configuration information, the first configuration information includes one of the interval between the PRB to be determined and the current PRB, the PRB index to be determined and the corresponding channel The number of repeated transmissions on each PRB, the corresponding channel includes the PDCCH ...

Abstract

The present disclosure relates to an information transmission method and device, an information receiving method and device, a base station, user equipment, and a computer-readable storage medium. Wherein, the information transmission method includes: determining the physical resource block PRB used to transmit the associated channel of the current physical downlink control channel PDCCH, wherein the determined PRB includes a PRB different from the current PRB used to transmit the current PDCCH; through the determined The channel corresponding to the PRB transmission. In the embodiment of the present disclosure, the PRB used to transmit the associated channel of the current PDCCH or the PRB used to repeatedly transmit the current PDCCH is determined. Since the determined PRB includes a different PRB from the current PRB used to transmit the current PDCCH, the selected When the determined PRB transmits the corresponding channel, service congestion due to excessive load on a certain PRB can be avoided, and scheduling flexibility can be improved.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular, to an information transmission method and device, an information receiving method and device, a base station, user equipment, and a computer-readable storage medium. Background technique [0002] Narrow Band Internet of Things (NB-IoT for short) is a very promising cellular Internet of Things technology, widely used in smart cities, such as meter reading, smart agriculture, such as temperature, humidity and other information collection, smart Transportation, such as shared bicycles and many other fields. [0003] At present, the NB-IoT communication framework has been formed in Long Term Evolution (LTE for short), which has the characteristics of supporting low complexity or low cost, coverage enhancement and power saving. [0004] In order to realize the low-complexity and low-cost characteristics of NB-IoT, the communication bandwidth of NB-IoT terminals is...
