Description

Embodiments of the present invention relate to the field of wireless communication technology, in particular to information transmission methods and devices.

In wireless communication, the base station needs to send system information to the UE. The UE can acquire the relevant network configuration information only after receiving the system information in order to access the base station and communicate with the base station.

The system information transmitted by the base station to the UE includes system information such as a system information block (SIB) and / or a master information block (MIB). The system information is information broadcast by the base station to all UEs in the coverage area. The base station further transmits information such as paging information, random access response (RAR) messages, and conflict resolution messages to the UE. The characteristics of this information are as follows. The information is broadcast to the UE by the base station, which can send the same information to a group of UEs, and the base station can send different information to multiple groups of UEs. In addition, the base station provides the UE with control information for scheduling system information, control information for scheduling RAR messages, control information for scheduling paging messages, or control information for scheduling conflict resolution messages. Need to send more.

Currently, with the development of Machine-to-Machine (M2M) technology, there are multiple UEs with low complexity or low cost in the network. Low-complexity or low-cost UEs support (radio frequency and / or baseband) bandwidth below the maximum carrier bandwidth specified in the system or below a specific frequency bandwidth. If a low-complexity or low-cost UE is served on a carrier that has more bandwidth than the low-complexity or low-cost UE supports, the UE will only have one subband resource of the carrier. Data can be received or transmitted at the same time. The base station provides information such as system information, RAR messages, paging messages, or conflict resolution messages (or control information for scheduling information such as system information, RAR messages, paging messages, or conflict resolution messages). When transmitting on only one subband resource, information such as RAR messages, paging messages, or conflict resolution messages (or control information for scheduling information such as RAR messages, paging messages, or conflict resolution messages) Capacity is limited.

To increase the capacity of information such as RAR messages, paging messages, or conflict resolution messages (or control information for scheduling information such as RAR messages, paging messages, or conflict resolution messages), the base station is a system. Information such as information, RAR messages, paging messages, or conflict resolution messages (or control information for scheduling information such as system information, RAR messages, paging messages, or conflict resolution messages) in all subbands of the carrier. Transmit on resources. However, as a result, the base station transmits a lot of repetitive system information (or control information for scheduling the system information), wasting system resources and increasing the power consumption of the base station.

Also, in a carrier aggregation scenario, if multiple carriers are configured in the base station, system information, RAR messages, paging messages, or conflict resolution messages (or system information, RAR messages, paging messages, or conflict resolution messages, etc.) (Control information for scheduling information) is transmitted only on the primary component carrier. Therefore, the problem of limited capacity still exists.

In wireless communications, the bandwidth supported by low-complexity or low-cost UEs for signal reception / transmission is less than the maximum carrier bandwidth specified by the system, or less than a specific carrier bandwidth. For example, current Long Term Evolution (LTE) communication systems specify a total of six system bandwidths of 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz, and 20MHz, but with low complexity or low complexity. The bandwidth supported by cost UE is typically less than 20MHz. For example, the signal bandwidth that can be supported by a low complexity or low cost UE is 1.4MHz, or a frequency bandwidth of Physical Resource Block (PRB) N (N is a positive integer, eg N = 6). Is. In LTE systems, one PRB occupies a frequency resource of 180KHz.

For convenience, frequency resources that can be supported or processed by low complexity or low cost user equipment can be referred to as subbands (in the present invention, subbands can be narrowbands). When a low complexity or low cost UE is serviced, the UE may need to receive information on multiple subband resources. For example, multiple subband resources are defined on carriers whose bandwidth is greater than the bandwidth supported by low complexity or low cost UEs. A low-complexity or low-cost UE can receive or send information about only one subband resource at a time. A subband resource refers to a frequency resource that occupies a specific frequency width on a carrier. For example, a subband can include one or more PRBs, or can include one or more subcarriers. Alternatively, the frequency resource width and frequency resource location of the subband are predetermined or preset. Typically, the frequency width occupied by a single subband resource is less than or equal to the bandwidth that can be supported by a low complexity or low cost UE. In the present invention, low complexity or low cost UEs are used as examples of UEs to illustrate methods of implementing embodiments of the present invention.

From Figures 3 and 4, system information, RAR messages, paging messages, and conflict resolution messages (or control channels for scheduling system information, RAR messages, paging messages, or conflict resolution messages) are on the primary component carrier. Only transmitted on or the system information, RAR message, paging message, and conflict resolution message (or control channel for scheduling system information, RAR message, paging message, or conflict resolution message) is of the carrier. It can be seen that it is transmitted only on one common subband resource. Transmit system information, RAR messages, paging messages, and conflict resolution messages (or control channels for scheduling system information, RAR messages, paging messages, or conflict resolution messages) on the primary component carrier or common subband resource. The capacity for is very limited. For example, the control channel for scheduling system information, RAR messages, paging messages, or conflict resolution messages is a control within the Common Search Space (CSS) or the enhanced common search space (eCSS). Limited by the number of channel elements, resulting in a limited number of control channels for scheduling system information, RAR messages, paging messages, or conflict resolution messages. Similarly, the transmission of system information, RAR messages, paging messages, and conflict resolution messages is limited by the size of the primary component carrier or the size of common subband resources, and as a result, system information, RAR messages, paging messages that may be supported. , And conflict resolution messages are restricted. In particular, considering the transmission of system information, RAR messages, paging messages, and conflict resolution messages to the UE with a single receiving antenna, the amount of system information that can be transmitted on limited resources, or on limited resources. The RAR, paging, or conflict resolution messages that can be transmitted by are further limited.

To solve the problem of limited capacity when sending information over carriers with multiple subbands as shown in Figure 4, system information, RAR messages, paging messages, and conflict resolution messages (or) are currently available. , System information, RAR messages, paging messages, or control channels for scheduling conflict resolution messages) can be transmitted over multiple subband resources on a carrier. As shown in FIG. 5, FIG. 5 is a schematic diagram for transmitting information on a plurality of subbands on a carrier including the plurality of subbands.

In the solution shown in Figure 5, the RAR message, paging message, and conflict resolution message are messages for a group of UEs. In the solution shown in Figure 5, the step of transmitting RAR messages, paging messages, and conflict resolution messages (or control channels for scheduling RAR messages, paging messages, or conflict resolution messages) over multiple subbands is , May increase paging capacity or affect random access of more UEs.

The solution shown in FIG. 5 can solve the problem of limited capacity when transmitting information on the carrier. However, since the system information (or the control channel for scheduling the system information) is a common message for all UEs, the system information (or the control channel for scheduling the system information) is used for all subband resources. When transmitted, a lot of repetitive system information (or control channels for scheduling system information) is transmitted, which wastes system resources and wastes power consumption of the base station.

Optionally, low complexity or low cost UEs have limited receive or transmit bandwidth. Therefore, low complexity or low cost UE unicast information (unicast data and / or control information for scheduling unicast data) is low complexity or low cost UE RAR message, paging message, or If not sent on the same subband resource as the conflict resolution message (or RAR message, paging message, or control channel for scheduling conflict resolution messages), the UE will use the subband resource to receive unicast information. , RAR messages, paging messages, and conflict resolution messages (or control channels for scheduling RAR messages, paging messages, or conflict resolution messages) must perform a handover with a subband resource. Must be. As a result, UE power consumption is wasted and standard complexity increases.

As a result, in the solution of FIG. 5, the system information is transmitted in each subband resource, and as a result, a lot of repeated system information is transmitted, the system resource is wasted, and the power consumption of the base station is wasted. .. Also, low complexity or low cost UE unicast information (unicast data and / or control information for scheduling unicast data) can be low complexity or low cost UE RAR messages, paging messages, or If not sent on the same subband resource as the conflict resolution message (or RAR message, paging message, or control channel for scheduling conflict resolution messages), the UE will unicast information (unicast data and / or unicast). Subband resources to receive (control information for scheduling data) and RAR, paging, or conflict resolution messages (or control channels for scheduling RAR, paging, or conflict resolution messages). Must be performed to and from the subband resource to receive. As a result, UE power consumption is wasted and standard complexity increases.

As a result, in multi-subband or carrier aggregation scenarios, the transmission of information such as system information, RAR messages, paging messages, and conflict resolution messages has certain drawbacks. Embodiments of the present invention provide information transmission methods and devices for solving the above drawbacks.

The information transmission method and apparatus according to the embodiment of the present invention can be applied to any communication system. If an entity in the communication system can send one or more of system information, RAR messages, paging messages, or conflict resolution messages, then in the communication system, for example, a Long Term Evolution (LTE) system Or there is another entity that can receive one or more of system information, RAR messages, paging messages, or conflict resolution messages, such as Long Term Evolution Advanced (LTE-A) systems. ..
