Description

System information sending method, receiving method and device

Technical Field

The present invention relates to the field of communications, and in particular, to a method and an apparatus for sending and receiving system information.

Background

Cellular mobile communication technology has entered the 4G era through a few decades of development, and research into 5G technology has been undertaken in order to meet the anticipated future demands for higher, faster, and more up-to-date communications. In 2G, 3G and 4G mobile communication systems, the transmission mechanism of system information is generally similar, but there are some differences in detail, and the common features are:

each cell transmits complete system information in a broadcast (broadcast) mode; the system Information is divided into a plurality of system Information blocks SIB (System Information Block) according to characteristics and functions; from the view point of the configuration mode of the information such as the resources and control parameters used by the broadcast, 3 modes of fixing (predefining), pre-configuring and dynamic allocation are generally adopted. Wherein fixed (predefined) generally refers to configuration information where the system explicitly defines the relevant resources and control parameters through some form (e.g., standard specification); dynamic scheduling generally means that configuration information of relevant resources and control parameters is dynamically sent to a receiving party through a physical layer channel, and the relevant configuration information is only valid within a time range defined by dynamic scheduling; pre-configuration generally means that the relevant resources and control parameters are configurable and their configuration information is sent to the receiver in the form of layer 2 and layer 3 messages, as long as the sender is not updated, the relevant configuration information is valid. In 3G and 4G systems, the resources and control parameters related to a system Information block MIB (main Information Block) adopt a fixed (predefined) configuration mode, the resources and control parameters related to an SIB1 in 4G adopt a mode of combining fixed and dynamic allocation, the resources and control parameters related to other SIBs in 3G and 4G adopt a pre-configuration mode wholly or partially, the configuration Information related to the SIB adopting the pre-configuration mode comprises scheduling Information, wherein the scheduling Information of 3G is sent through MIB or a special SB (scheduling block), and the scheduling Information of 4G is sent through SIB 1. The scheduling information includes resource and control information related to each SIB broadcast, such as in time domain, including time point (or window) and transmission period of transmission, each SIB will be broadcast and transmitted periodically continuously according to the scheduling information; from the perspective of UE usage, the effective range of almost all system information is limited to only the cell where it is transmitted, i.e. when the UE moves from one cell and reselects to another cell, the system information transmitted by the new cell needs to be received completely again in the new cell.

Under the above system information transmission mechanism, with the continuous introduction of new technologies, the number of transmission blocks increases, the content of system information becomes larger, and the number of consumed resources increases. Moreover, the chances that a number of transport blocks for a particular new technology are actually required are relatively limited, and the continuous broadcast transmission may result in wasted resources and increased power consumption of the network-side device.

In view of the above problems, a new system information transmission mechanism is proposed, which is summarized as follows:

the system information is divided into two categories according to the importance degree of the information, one category is necessary system information which is called Minimum system information (Minimum SI) in the text, and the information is still transmitted by adopting a broadcasting mechanism; another category includes all Other system information, referred to herein as Other SI, transmitted on-demand (on-demand) and using dedicated signaling (dedicated signaling), broadcast or multicast mechanisms.

The Minimum SI generally includes very critical system information related to cell selection and initial access (including acquisition of Other SI), and the information is transmitted in a periodic broadcast manner, so that information to be broadcast and transmitted is greatly compressed; other system information is transmitted according to the needs of the user equipment or the network side base station equipment, such as Node B, and may be transmitted in a dedicated signaling (dedicated signaling) or broadcast (broadcast) or multicast (multicast) manner, instead of continuously and periodically, so as to improve the resource utilization efficiency.

For both types of system information described above, a structure is still used which is divided into a plurality of system information blocks SIB by feature and/or function.

For broadcast transmission, the proposed scheme is shown in fig. 1, and fig. 1 is a schematic diagram of a broadcast transmission mechanism of Other SI.

The transmission is performed based on an SI window (system information window), which has a similar concept to LTE; i.e. some periodic SI windows are predefined in the form of scheduling information in which the SIB of the Other SI will be broadcast. The SI window comprises a sending window and a window period, and is a period of time defined by a time and/or radio frame, subframe or time slot isochronous domain concept; the setting of the sending window comprises a starting point and a window length, or the starting point and an end point, and the window period comprises a period length.

The SI window scheduling information related to the Other SI is broadcasted in the Minimum SI, wherein the mapping relationship between the SIB of the Other SI and the SI window is also possibly included; whether a certain SIB is being broadcast is indicated by whether the Minimum SI includes scheduling information for the SIB.

An important development direction of the 5G mobile communication system is to use a high frequency spectrum with a large bandwidth to carry a large amount of traffic. Considering that the path loss increases exponentially with the frequency of a radio signal, the coverage of the high-frequency mobile communication technology becomes a fatal problem, that is, if an omnidirectional transmission method as low frequency is adopted, a high-frequency system with a certain transmission power can only cover a small area. To overcome this problem, a directional transmission technique using a beam forming (beam forming) technique will be used for high-frequency wireless signal transmission. The beamforming technology can longitudinally expand the signal coverage in a radius, but the coverage in a transverse direction is greatly reduced, and the number of beams (beam) which can be simultaneously transmitted by a network side device base station is often limited, so that the beam scanning (beam scanning) technology is introduced to meet the requirement of transverse signal coverage for the transmission of broadcast or multicast signals. The beam scanning technique may be implemented using time and/or frequency domain based methods. As shown in fig. 2, the concept of Scanning Block (SB) is introduced in the time domain, a beam transmitted in one scanning block can only cover a part of a cell, and a plurality of scanning blocks are used to cover the whole cell, and the plurality of scanning blocks are called scanning arrays (scanning bursts). However, the beam scanning technique imposes a great limitation on the use of resources, for example, when the scanning of the broadcast channel requires the beam to be transmitted to a certain direction, although the broadcast channel uses only a few frequency domain resources, other frequency domain resources are also limited to be used only in the certain direction, which greatly affects the use efficiency of the frequency spectrum resources. The beam scanning technique is therefore used as little as possible, including minimizing the time required to scan the block and scan the array.

The amount of information of the Other SI is variable, but the amount of information is relatively large, so that the occupied time domain and/or frequency domain resources during broadcasting may also be large, which is contradictory to the requirements of the beam scanning technology.

and the base station sets all the indication bits in the beam transmission indication information in the MIB, namely to 1, and transmits the indication bits through a fourth broadcast channel.

And the base station sends (broadcasts or multicasts) one or more SIBs of the Other SI through a fifth broadcast channel by all the sweet blocks in one sweet burst in the SI window corresponding to the Other SI according to the scheduling information of the Other SI. The transmission may also be transmitted multiple times within a predefined time period according to a predefined periodicity within one SI window time range and/or multiple times within a predefined periodicity within multiple SI window time ranges. In particular, the SIBs of one or more Other SIs transmitted by all listening blocks are typically the same.

Optionally, before the sending, the base station may also send an Other SI update notification message through a sixth broadcast channel.
