Description

Control information processing method, terminal and transmission point

Technical Field

The present application relates to communication technologies, and in particular, to a control information processing method, a terminal, and a transmission point.

Background

In a deployment scenario of a wireless communication system, for example, a heterogeneous network (Heterogeneous Network, hetnet), more and more micro base stations are deployed as required in a network where only a macro base station originally achieves full coverage, and when a system message update is required, the macro base station or the micro base station sends a Paging message to a terminal in a corresponding cell, and notifies the terminal of the update of the system message through the Paging message. After receiving the paging message, the terminal may acquire the updated system message from the corresponding macro base station or micro base station.

However, due to multiplexing of time-frequency resources, the terminals in the cells corresponding to the micro base station may be interfered by the macro base station or other micro base stations, or the terminals in the cells corresponding to the macro base station may be interfered by the micro base station, so that the interfered terminals cannot correctly receive the updated system message, which results in a decrease in reliability of system message acquisition. Similar problems can exist with the acquisition of other common control information.

Detailed Description

In a heterogeneous network (Heterogeneous Network, hetnet) deployment scenario of a wireless communication system, one cell identity may correspond to one transmission point (Transmission Point, TP), or one cell identity may also correspond to multiple TPs, each TP typically having different Reference Signal (RS) resources. The TP may include Macro base stations (Macro) and Micro base stations, for example, the Micro base stations may be stations such as Micro base stations (Micro), pico base stations (Pico), remote radio heads (Remote Radio Head, RRH for short), relay devices (Relay), or Femto base stations (Femto).

The technical scheme of the application can be applied to various communication systems, such as a global system for mobile communication (Global System for Mobile Communications, abbreviated as GSM), a general packet radio service (General Packet Radio Service, abbreviated as GPRS) system, a code division multiple access (Code Division Multiple Access, abbreviated as CDMA) system, a CDMA2000 system, a wideband code division multiple access (Wideband Code Division Multiple Access, abbreviated as WCDMA) system, a long term evolution (Long Term Evolution, abbreviated as LTE) system or a worldwide interoperability for microwave access (World Interoperability for Microwave Access, abbreviated as WiMAX) system.

The macro base station may be a base station (Base Transceiver Station, abbreviated as BTS) in a GSM system, a GPRS system, or a CDMA system, or a base station (NodeB) in a WCDMA system, or an evolved base station (Evolutional Node B, abbreviated as eNB or eNodeB) in an LTE system, or a network element such as a base station (Access Service Network Base Station, abbreviated as ASN BS) of an access service network in a WiMAX network.

In addition, the term "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.

Fig. 1 is a flowchart of a control information processing method according to an embodiment of the present application, as shown in fig. 1.

101. The terminal determines at least one first resource of a first common control channel.

102. And the terminal receives the public control information sent by the transmission point through the first public control channel according to the at least one first resource.

It should be noted that the first resource may include a time domain location and a frequency domain location.

Alternatively, in one possible implementation of this embodiment, the common control information may include, but is not limited to, one or more of a master message block (Master Information Block, MIB) information, control information for MIB information scheduling, scheduling information for first system message block (System Information Block, sib1) information, SIB1 information, and a synchronization signal. The synchronization signals may include, but are not limited to, primary synchronization signals (Primary Synchronization Signal, PSS) and secondary synchronization signals (Second Synchronization Signal, SSS), among others.

Wherein the MIB information may include all or part of the MIB information in the current system, or may further include other information than the MIB information in the current system.

Specifically, MIB information in the current system includes downlink bandwidth, system frame number, configuration information of a physical hybrid automatic request retransmission indicator channel (Physical HARQ Indicator Channel, PHICH) and antenna configuration information of Cell-specific reference signals (Cell-specific Reference Signal, CRS).

In particular, the other information may include one or more combinations of scheduling information, enhanced PHICH configuration information based on UE-specific reference signal (UE-specific Reference Signal, UERS) demodulation, antenna port configuration information of the UERS, and resource configuration information of a common search space.

For example, as for the scheduling information, the scheduling information is used for scheduling a physical channel, for example, a physical downlink shared channel (Physical Downlink Shared Channel, PDSCH), and the control information for MIB information scheduling is carried in the physical channel, for example, the control information for MIB information scheduling may include a system frame number, antenna port configuration information of UERS, resource configuration information of a common search space, resource configuration information of scheduling information of SIB1 information, and the like, and other combinations of control information are not excluded. The resources occupied by the physical channel, e.g., PDSCH, scheduled by the scheduling information may be within a preconfigured bandwidth, e.g., a bandwidth of 6 physical resource blocks (Physical Resource Block, PRB), and other preconfigured bandwidths are not excluded, so that a UE of a low cost type, e.g., a UE of a machine type communication (Machine Type Communication, MTC), may be supported, and the reception bandwidth of the UE of the type is limited.

For example, for the antenna port configuration information of the UERS, which of the two configurations, for example, antenna port 7 of the uers+antenna port 9 of the UERS, or antenna port 8 of the uers+antenna port 10 of the UERS, is used for demodulating the physical downlink control channel carried in the common search space may be notified.

Wherein MIB information in the current system is transmitted on a physical broadcast channel (Physical Broadcasting Channel, PBCH) that is not used to schedule other physical channels. The MIB information in the present application may be used to schedule other physical channels, e.g., physical downlink shared channels (Physical Downlink Shared Channel, PDSCH), which may carry control information for MIB information scheduling.

Optionally, in a possible implementation manner of this embodiment, the at least one first resource is one first resource.

Accordingly, in 102, the terminal may specifically receive, on the determined one first resource, common control information sent by the transmission point through the first common control channel.

Specifically, in 101, the terminal may specifically determine the one first resource, e.g. a protocol contract, according to pre-configured resource information. For example, the time domain position of the one first resource may be a fixed subframe number, e.g. subframe 0, the frequency domain position of the one first resource may be a fixed physical resource block (Physical Resource Block, PRB) or a PRB pair, e.g. the frequency domain position of the one first resource may also be within a frequency bandwidth of 6 PRB pairs of the carrier center.

Optionally, in a possible implementation manner of this embodiment, the at least one first resource is at least two first resources.

Accordingly, in 102, the terminal may specifically determine one first resource from the at least two first resources; and the terminal receives the public control information sent by the transmission point through the first public control channel on the determined first resource.

For example, the terminal may receive second indication information sent by the transmission point, where the second indication information is used to indicate one of the at least two first resources.

Correspondingly, in 102, the terminal may specifically perform blind detection on the at least two first resources, so as to receive common control information sent by the transmission point through the first common control channel.

Specifically, in 101, the terminal may specifically determine the at least two first resources, e.g. protocol conventions, according to pre-configured resource information. For example, the time domain positions of the at least two first resources may be some subframes of 10 subframes of one radio frame, or the time domain positions of the at least two first resources may be some subframes of 20 subframes of two radio frames, the frequency domain positions of the at least two first resources may be 6 PRB pairs within a frequency bandwidth that the terminal can identify when the downlink carrier bandwidth is not acquired, or the frequency domain positions of the at least two first resources may be 6 PRB pairs within a frequency bandwidth occupied by the synchronization channel, and other frequency bandwidths are not excluded, e.g., 8 PRB peering.

The minimum unit of each first resource in the at least one first resource is a physical resource block (Physical Resource Block, PRB), a PRB pair, a resource set corresponding to an enhanced control channel element (Enhanced Control Channel Element, eCCE), or an enhanced resource element group (Enhanced Resource Element Group, eREG).

For example, 2 PRB pairs may be defined as the resource location of one first resource.

For another example, 2 eregs may be defined as resource locations of one first resource. The eREG in the first resource may be dispersed in a plurality of PRB pairs to obtain a frequency diversity gain.

Specifically, in 101, the terminal may specifically further receive first indication information sent by the transmission point, where the first indication information is used to indicate the at least two first resources. Specifically, the terminal may specifically receive the first indication information sent by the transmission point through a synchronization channel, a higher layer signaling, or a control channel.

For example, the first indication information is a cell identifier carried in the synchronization channel, where the cell identifier may indicate at least two first resources to the UE. Taking the time domain resource as an example, the cell identity may indicate that the set of transmission subframes of the first resource is one of subframes numbered 0 to 4 or subframes numbered 5 to 9. Of course, other cases are not excluded. Taking the frequency domain resource as an example, assuming that the preconfigured bandwidth is 8 PRB pairs and each first resource occupies 2 PRB pairs, the cell identity may indicate that the frequency domain resource of the first resource is the resource sets {0,1} and {2,3}, or the resource sets {4,5} and {6,7}. Of course, other cases are not excluded.

For example, the higher layer signaling may be a radio resource control (Radio Resource Control, RRC) message, specifically, the first indication information may be carried by an information element (Information Element, IE) in the RRC message, where the RRC message may be an RRC message in the prior art, for example, an RRC connection reconfiguration (RRC CONNECTION RECONFIGURATION) message, etc., which is not limited in this embodiment, and the first indication information may be carried by extending an IE of an existing RRC message, or the RRC message may also be an RRC message different from the existing RRC message in the prior art.

For another example, the higher layer signaling may be a media access Control (Media Access Control, MAC) Element (CE) message, and specifically, the first indication information may also be carried by adding a new MAC CE message.

As another example, the control channel may be a physical downlink control channel (Physical Downlink Control Channel, PDCCH) or an Enhanced PDCCH (ePDCCH), the latter demodulated based on UERS, the former demodulated based on a common reference signal (Common Reference Signal, CRS). Specifically, the terminal may receive the first indication information that the transmission point sends to the terminal through the PDCCH, or may also receive the first indication information that the transmission point sends to the group to which the terminal belongs through the PDCCH.

Optionally, after determining the set of at least two first resources by using the method, the terminal may perform blind detection on MIB information in the set to receive MIB information and/or MIB information scheduling control information; or the terminal can also perform blind detection on the scheduling information of the SIB1 information in the set so as to receive the scheduling information of the SIB1 and/or the SIB1 information; or the terminal may further receive the second indication information, where the second indication information is used to indicate one of the at least two first resources. For example, the second indication information may be cell identification information carried in a synchronization channel.

Further, the determined one first resource is different in at least two subframes. Specifically, taking MIB information as an example (similar processing for scheduling information of SIB1 information), the same MIB information may be repeatedly transmitted a plurality of times over a plurality of subframes, for example, four times over four radio frames, each of which is transmitted once, the contents of the four times being the same, so as to obtain combining gain improvement performance. Assuming that MIB information of one cell is transmitted on the first two PRB pairs {0,1} of the 6 PRB pairs in the bandwidth center of the current downlink carrier, even if four combinations are available, if the two PRB pairs are in deep fading of the channel for a certain UE, the performance is poor, and even correct demodulation is not possible. In addition, the current MIB information has 4 symbols in 6 PRB pairs in the bandwidth center, so there is an influence on the resource mapping of the ePDCCH, that is, the ePDCCH with the PRB or PRB pair as the resource allocation granularity can occupy fewer resource units in each PRB pair in the 6 PRB pairs in the bandwidth center, which is also the reason that the ePDCCH in the LTE system of release 11 cannot transmit the ePDCCH on the PRB pair in which the MIB information is located. Therefore, a certain rule can be introduced to ensure that the MIB information repeatedly transmitted for four times occupies different frequency domain resource positions to obtain frequency domain diversity gain, and the demodulation performance of the MIB information can be improved by combining the four times of combining gain. For example, MIB information is transmitted N times in a first period, the N times of MIB information transmitted are identical, and N times of MIB information transmitted in a next first period may be changed; and, N times of MIB information in the first period are transmitted in the second period, and frequency domain resource patterns occupied by at least two transmissions of the N times of MIB information are different. Alternatively, the resource pattern of N times of transmission of MIB information in one first period is repeated in each first period, i.e., the resource positions of the above MIB information in a plurality of first periods are cyclic. The first period and the second period may be preconfigured or indicated by a cell identity. For example, the first period is 40 milliseconds and the second period is 10 milliseconds. The above N is equal to 4. For example, a preconfigured rule is adopted, or based on blind detection of the UE or based on indication of cell identification, so that PRB pairs occupied by MIB information of four repeated transmissions in one first period are {0,1}, {2,3}, {4,5} and {0,1}, respectively, and four transmissions in other first periods are repetitions of the above resource pattern. Of course, other resource distribution rules are not excluded nor are other minimum resource granularities excluded, e.g. four different resource patterns in PRB pairs, ecces or eregs. In this embodiment, different transmission points may select different first resources to implement interference avoidance of a common control channel, so as to avoid the problem in the prior art that a terminal in a cell corresponding to a micro base station may be interfered by a macro base station or other micro base stations due to multiplexing of time-frequency resources, or a terminal in a cell corresponding to a macro base station may be interfered by a micro base station, so that the terminal may correctly receive common control information sent by the transmission point. In addition, the MIB information is used for resource mapping in PRB or PRB pair units, for example, MIB information may occupy all symbols on 1 or 2 PRB pairs or all symbols except for symbols occupied by the synchronization signal, so that there is no influence on the resource mapping of ePDCCH, and therefore ePDCCH may not be used for MIB information mapping on the same PRB pair, and resource utilization is improved. In addition, although the frequency domain bandwidth occupied by the transmission of the MIB information at a time is reduced compared with the bandwidth of the previous 6 PRB pairs, the scheme of the present application can realize that the frequency domain resources occupied by the MIB information transmitted by a plurality of subframes are different to obtain the frequency domain diversity gain, and in addition, the different frequency domain resources can also carry other information, such as part of the information of the system radio frame number, the information of the antenna ports, and the like.

Optionally, in a possible implementation manner of this embodiment, after 102, the terminal may further determine the second resource according to the common control information.

It should be noted that the second resource may include a time domain location and a frequency domain location.

Specifically, for the case where the common control information is MIB information or control information scheduled by MIB information. Accordingly, the second resource may then include a time-frequency resource of a second common control channel carrying scheduling information of SIB1 information.

For example, the terminal may specifically determine one second resource from at least two second resources according to the common control information, or the common control information and a cell identifier of a cell in which the terminal is located. Wherein the at least two second resources may be preconfigured, e.g. protocol defined. Specifically, the frequency domain resource may be a PRB pair of full bandwidth, because the information of the downlink bandwidth is already available in the MIB information; the time domain resource may be 1 subframe or may also be several subframes of a plurality of radio frames.

Specifically, the terminal may specifically determine one second resource from the at least two second resources according to a cyclic redundancy check (Cyclic Redundancy Check, CRC) of the MIB information and/or bits in the MIB information. For example, if the frequency domain resource is assumed to have 4 and the time domain resource is assumed to be fixed subframe 5, one of the second resources may be indicated by two bits in MIB information, or one of the second resources may also be indicated by two CRCs of MIB information and one bit in MIB information.

Specifically, the terminal may determine one second resource from the at least two second resources according to the CRC of the MIB information and/or bits in the MIB information, and a cell identifier. For example, if there are 4 frequency domain resources and the time domain resource is assumed to be fixed subframe 5, 2 second resources of the 4 assumed resources may be determined by the cell identity, and then one of the second resources may be specifically indicated by one bit in MIB information or two CRCs of MIB information. Similarly, other resource hypotheses numbers and indication methods are not precluded.

Optionally, after the terminal determines one second resource from at least two second resources according to the common control information, or the common control information and the cell identifier of the cell where the terminal is located, the terminal may further receive, on the determined one second resource, scheduling information of SIB1 information sent by the transmission point through the second common control channel.

For example, the terminal may specifically determine at least two second resources from at least two second resources according to the common control information, or the common control information and a cell identifier of a cell in which the terminal is located.

It will be appreciated that the terminal determines a small set of second resources from a large set of second resources. The large set of second resources may be preconfigured, e.g. protocol defined. Specifically, the frequency domain resource may be a PRB pair of full bandwidth, because the information of the downlink bandwidth is already available in the MIB information; the time domain resource may be 1 subframe or may also be several subframes of a plurality of radio frames.

Specifically, the terminal may specifically determine at least two second resources from the at least two second resources according to a cyclic redundancy check code (Cyclic Redundancy Check, CRC) of the MIB information and/or bits in the MIB information. For example, if the frequency domain resource is assumed to be 16, the time domain resource is assumed to be fixed subframe 5, and each small set of second resources includes 4 second resources, the small set of second resources may be indicated by two bits in MIB information, or may also be indicated by two CRCs of MIB information and one bit in MIB information.

Specifically, the terminal may determine at least two second resources from the at least two second resources according to the CRC of the MIB information and/or bits in the MIB information, and a cell identity. For example, if the frequency domain resource is assumed to have 16, the time domain resource is assumed to be fixed subframe 5, and each small set of second resources includes 4 second resources, 8 second resources in the 16 assumed resources may be determined through the cell identification first, and then the small set of second resources may be specifically indicated through one bit in MIB information or two CRCs of MIB information. Similarly, other resource hypotheses numbers and indication methods are not precluded.

Optionally, after determining at least two second resources from at least two second resources according to the common control information or the common control information and the cell identifier of the cell where the terminal is located, the terminal may further perform blind detection on the determined at least two second resources, that is, on the set of small second resources, so as to receive scheduling information of SIB1 information sent by the transmission point through the second common control channel.

It should be noted that the at least one first resource may be within a pre-configured bandwidth. For example, the downlink bandwidth that the UE can assume before acquiring MIB information, such as a bandwidth of 6 PRBs, is not limited to any other bandwidth as long as it is predefined.

Specifically, the terminal performs blind detection on the determined at least two second resources (i.e. the small set of second resources), and takes scheduling information of SIB1 information sent by the transmission point through the second common control channel as an example. Wherein the small set of second resources may comprise several PRB pairs on one or more subframes. Taking the time domain resource as an example, the time domain resource may be a fixed subframe, for example, subframe No. 5, i.e. subframe No. 5; taking frequency domain resources as an example, the frequency domain resources may be PRB pairs 1,2,3, and 4. The scheduling information of SIB1 information may be detected on the 4 PRB pairs, respectively, assuming that the scheduling information of SIB1 information is detected on a certain PRB, for example, from PRB pair 2.

Specifically, for the case where the common control information is MIB information or control information scheduled by MIB information. Accordingly, the second resource may then comprise a time-frequency resource of the common search space.

For example, the terminal may specifically determine one second resource from at least two second resources according to the common control information, or the common control information and a cell identifier of a cell in which the terminal is located. Wherein the at least two second resources may be preconfigured, e.g. protocol defined. Specifically, the frequency domain resource may be a PRB pair of full bandwidth, because the information of the downlink bandwidth is already available in the MIB information; for the common search space, the time domain resource is all subframes, and is not the second common control channel like the scheduling information carrying SIB1 information, but is only transmitted on a specific subframe.

Specifically, the terminal may specifically determine one second resource from the at least two second resources according to a cyclic redundancy check (Cyclic Redundancy Check, CRC) of the MIB information and/or bits in the MIB information.

For example, the determined one second resource is different in at least two subframes.

Specifically, there are second resources that are completely non-overlapping in the frequency domain among the at least two second resources.

For example, the PRB pair occupied by the ePDCCH transmitted in the second resource is the same as the PRB pair occupied by the second resource. For example, assuming that the common search space occupies 4 PRB pairs (other sizes are similar) on the frequency domain, the bandwidth of the downlink carrier is 100 PRB pairs, there are 25 candidate positions of the common search space that are not overlapped in total, that is, 25 frequency domain resources are included in a predefined set of at least two second resources, that is, large second resources, so that 5 bits in MIB information are needed for indication, or 2 CRC bits in MIB information and 4 bits in MIB information are needed for indication, or bits in CRC and/or MIB information of MIB information are needed for indication, and cell identity joint indication. Each candidate position in the above example is non-overlapping, and this non-overlapping manner may be applied to one or each ePDCCH in the common search space that may occupy resources in the 4 PRB pairs, i.e., one ePDCCH may be scattered over the 4 PRB pairs to obtain as large a frequency diversity gain as possible, so that the 4 PRB pairs occupied by each candidate position are not overlapped with each other to implement interference coordination of ePDCCH transmitted in the common search space between cells.

Specifically, there are second resources that overlap partially in the frequency domain among the at least two second resources.

For example, the PRB pair occupied by the ePDCCH transmitted in the second resource is part of the PRB pair occupied by the second resource. The candidate positions of the public search space can be mutually overlapped partially to improve the resource multiplexing capability, and the interference coordination of the ePDCCHs sent in the inter-cell public search space is kept, and the partially overlapped mode can be suitable for the following scenes: assuming that the size of the public search space still occupies 4 PRB pairs, but one or each ePDCCH occupies only 2 PRB pairs in the 4 PRB pairs, where the scenario includes a case where the bandwidth is smaller, such as a case where the bandwidth is 6 PRB pairs or 15 PRB pairs, where one ePDCCH cannot occupy too much bandwidth, such as 4 PRB pairs, where the capacity of the data channel may be limited due to excessive overhead of the control channel, so that candidate positions of the public search space in the case of the small bandwidth may be partially overlapped, such as a case where the bandwidth is 6 PRB pairs, where the public search space of cell 1 occupies PRB pairs {0,1,2,3}, where the public search space of cell 2 occupies PRB pairs {2,3,4,5}, where the public search space of cell 3 occupies {0,1,4,5}, i.e.e., partially overlaps with each other, but interference of the epdchs transmitted in the public search space between cells may still be achieved, such as at a certain moment, where cell 1 transmits 0 and 2 epdchs with the cell 2, and 3 dcch are not transmitted; while at other moments cell 1 transmits ePDCCH with PRB pairs 2 and 3, cell 3 transmits ePDCCH with PRB pairs 4 and 5, cell 2 does not, and so on.

For example, the terminal may specifically determine one second resource from the at least two second resources according to the jointly encoded downlink bandwidth indication information and the second resource indication information in the MIB information. In the MIB information, second resource indication information for indicating the second resource and downlink bandwidth indication information for indicating the downlink bandwidth may be jointly encoded. Specifically, the downlink bandwidth indication information in the MIB information, which indicates the downlink bandwidth, is 3 bits, specifically indicates 6 downlink bandwidths, and indicates the number of available PRB pairs {6, 15, 25, 50, 75, 100}; if the indication manner of the second resource is independent, for example, taking the indication of the common search space with each candidate position being 4 PRB pairs as an example, for a bandwidth of 100 PRB pairs, 5 bits are needed to indicate, that is, the total information bits in MIB information indicating the downlink bandwidth and the common search space is 8. In contrast, if the joint coding method of the downlink bandwidth indication information and the second resource indication information is adopted, signaling overhead can be saved, taking the indication information as a bit indication as an example, for the above 6 bandwidths, candidate positions of the included non-overlapping common search spaces are {1,3,6, 12, 18, 25}, and 65 in total, 7 bits are needed, and if 1 candidate position of 6 PRB pairs is fixed (assuming that the PRB pairs {0,1,2,3 }), 64 positions in total are needed, and 6 bits are needed. Alternatively, the method may include a case of partially overlapping common search space candidate positions, and if the number of partially overlapping PRB pairs is 2 for 6 PRB pairs of a small bandwidth, there are 3 candidate positions, and if the number of partially overlapping PRB pairs is 2 for 15 PRB pairs, there are 7 candidate positions, and if the number of partially overlapping PRB pairs is 3+7+6+12+18+25=71 for all PRB pairs, 7 bits are required.

Taking the LTE system as an example, since there are bandwidths of multiple downlink carriers in the LTE system, for example, there are 100 PRB pairs, 75 PRB pairs, 50 PRB pairs, 25 PRB pairs, 15 PRB pairs, or 6 PRB pairs, and bandwidths of adjacent cells may be different, the division of the frequency domain candidate positions needs to be considered, and the division is performed based on the bandwidth center of the downlink carrier, for example, the common search space size of 6 PRB pairs is also used as an example, and the division of the candidate positions is performed based on 6 PRB pairs in the frequency center of the current downlink carrier, and then the candidate positions are respectively arranged on two sides of the carrier. For example, the position of the common search space is indicated with 3 bits, and assuming that one frequency domain candidate position of the common search space occupies 6 PRB pairs, the state indication order of 3 bits is "000" representing the 6 PRB pairs in the center of the bandwidth, and "001" and "010" representing 6 PRB pairs adjacent to each other around the 6 PRB pairs in the center of the bandwidth, and so on, i.e., the arrangement order from the center to the both sides.

Specifically, the second resources included in the large set of second resources adopt a frequency hopping manner in the set, and parameters of the frequency hopping are determined by cell identification and time domain information, wherein the time domain information can be one or more of a combination of a frame number, a subframe number and a time slot number. The terminal may determine, according to the rule of frequency hopping, a time-frequency resource of the current common search space among the second resources included in the set. Therefore, the randomization effect of the time-frequency resource of the public search space on the frequency domain can be achieved, and the special channel of a certain terminal cannot be blocked greatly. Thus, the determined one second resource may be different in at least two subframes. In particular, the resource allocation of a group of public search spaces can be allocated to the terminal, and the resource allocation of different public search spaces in the group can be used on different subframes. The pattern of resource allocation of different common search spaces in the group may be directly notified to the terminal, or the terminal may be notified of the pattern of resource allocation of the common search spaces on sub-frames of the terminal, and then the terminal calculates the pattern of resource allocation of the common search spaces on other sub-frames based on a certain rule, which may be constructed based on one or more combinations of frame number, sub-frame number, slot number and cell identity.

For example, the terminal may specifically determine at least two second resources from at least two second resources according to the common control information, or the common control information and a cell identifier of a cell in which the terminal is located. Specifically, the method for determining at least two second resources may refer to related descriptions in the method for determining one second resource, which are not described herein.

It will be appreciated that the terminal determines a small set of second resources from a large set of second resources.

Optionally, after determining at least two second resources from at least two second resources according to the common control information or the common control information and the cell identifier of the cell in which the terminal is located, the terminal may further perform blind detection on the determined at least two second resources, so as to receive scheduling information of SIB1 information sent by the transmission point through the second common control channel; and the terminal can determine one second resource according to the scheduling information of the SIB1 information and/or the SIB1 information. That is, after blind detection of the scheduling information of the SIB1 information and the SIB1 information, the time-frequency resource of the common search space may be determined according to the scheduling information of the SIB1 information and/or the SIB1 information.

In particular, the terminal may determine at least two second resources (a set of large second resources) from the at least two second resources (a set of small second resources) in particular according to a cyclic redundancy check (Cyclic Redundancy Check, CRC) of the MIB information and/or bits in the MIB information.

For example, blind detection is performed on the second resources included in the small set of second resources to receive scheduling information of SIB1 information. The scheduling information of the SIB1 information is detected in which candidate location, it may be determined that the candidate location is a time-frequency resource of the common search space of the current cell, or the time-frequency resource of the common search space may be further indicated by the detected information in the SIB1 information.

Optionally, after the terminal determines one second resource from at least two second resources according to the common control information, or the common control information and the cell identifier of the cell where the terminal is located, or after the terminal determines one second resource according to the scheduling information of the SIB1 information and/or the SIB1 information, the terminal may further perform blind detection on the determined one second resource, so as to receive the common control information sent by the transmission point.

Specifically, for the case where the common control information is scheduling information of SIB1 information and/or SIB1 information. Accordingly, the second resource may include one or more of a combination of a time-frequency resource and a system radio frame number of the common search space, a downlink carrier bandwidth, configuration information of an enhanced physical hybrid automatic repeat request indicator channel (Physical Hybrid ARQ Indicator Channel, PHICH), an antenna port of a User Equipment (UE) Reference Signal (RS), and a scrambling code of the UERS.

For example, if the second resource is a time-frequency resource of the common search space, the terminal may specifically determine the time-frequency resource carrying the scheduling information of the SIB1 information as the second resource.

Specifically, taking a common downlink control channel of a scheduled SIB1 as an example of blind detection at a plurality of time-frequency resource locations, the plurality of time-frequency resources may be configured by a synchronization channel and/or MIB information, or pre-configured without signaling, and the plurality of time-frequency resources may include a plurality of PRB pairs on one or more subframes. Taking a fixed subframe as an example, assume that the time domain resource is a fixed subframe, such as subframe 5; assuming that there are 8 PRB pairs, each of which is further divided into N parts, for example, 4 parts a, b, c and d, the UE detects the scheduling information of SIB1 on the a part of the PRB pairs of 1 to 4 and on the a part of the PRB pairs of 5 to 8, respectively, and the 4 PRB pairs, i.e., PRB pairs 5 to 8, are resources of the common search space, provided that the scheduling information of SIB1 is detected from the a part of the last 4 PRB pairs.

For another example, if the second resource is a time-frequency resource of a common search space, the terminal may specifically determine the time-frequency resource carrying the scheduling information of the SIB1 information as a first portion of the second resource, and determine, according to the scheduling information of the SIB1 information and/or the SIB information, a second portion of the second resource, where the second resource is composed of the first portion and the second portion.

Specifically, taking a common downlink control channel of a scheduled SIB1 as an example of blind detection at a plurality of time-frequency resource locations, the plurality of time-frequency resources may be configured by a synchronization channel and/or MIB information, or pre-configured without signaling, and the plurality of time-frequency resources may include a plurality of PRB pairs on one or more subframes. Taking a fixed subframe as an example, assume that the time domain resource is a fixed subframe, such as subframe 5; for a plurality of PRB pairs, assuming that PRB pairs 1,2,3 and 4 are respectively detected on the 4 PRB pairs, if the SIB1 scheduling information is detected on a certain PRB, for example, detected from PRB pair 2, the PRB pair 2 is a resource of the SIB1 scheduling information, and it may be further determined that the resource is a part of the common search space resource; then, according to the scheduling information of the SIB1 information and/or the SIB information, a second part of the public search space is determined, namely the public search space is composed of the first part and the second part.

For another example, if the second resource is a time-frequency resource of a common search space, the terminal may specifically determine the second resource according to the scheduling information of the SIB1 information and/or the SIB1 information. Wherein, the second resource is independent of the time-frequency resource carrying the scheduling information of the SIB1 information.

Specifically, taking a common downlink control channel of a scheduled SIB1 as an example of blind detection at a plurality of time-frequency resource locations, the plurality of time-frequency resources may be configured by a synchronization channel and/or MIB information, or pre-configured without signaling, and the plurality of time-frequency resources may include a plurality of PRB pairs on one or more subframes. Taking a fixed subframe as an example, assume that the time domain resource is a fixed subframe, such as subframe 5; for a plurality of PRB pairs, assuming that PRB pairs 1,2,3 and 4 are respectively detected on the 4 PRB pairs, if the SIB1 scheduling information is detected on a certain PRB, for example, detected from PRB pair 2, the PRB pair 2 is a resource of the SIB1 scheduling information, but the resource may not be a part or all of the common search space resources; and further determining the resources of the common search space according to the scheduling information and/or the SIB information of the SIB1 information, wherein the resources of the common search space are independent from the resources of the scheduling information of the SIB 1.

In this embodiment, the method for receiving the scheduling information of the SIB1 information by the terminal may be one of the following methods:

A. and the terminal receives the scheduling information of the SIB1 information according to a pre-designated load size, wherein the load size corresponds to the bandwidth of a carrier wave in which the terminal works currently.

Assuming that the UE has not acquired the downlink bandwidth when detecting the common downlink control channel of the scheduling SIB1, the payload size (payload size) of the common downlink control channel of the scheduling SIB1 may be determined according to a maximum downlink carrier bandwidth reserved or other preconfigured bandwidths, and after the detection, the downlink bandwidth may be carried in the scheduling information of the SIB1 and/or in the SIB1 information. For ePDCCH carried in SIB1 scheduling information, i.e. scheduling SIB1 information, any combination of redundancy bits or redundancy states in the ePDCCH, e.g. new data indication (New Data Indicator, NDI) bits, transmit power control (Transmit Power Control, TPC) bits or states, bits or states of HARQ process numbers may be employed.

B. And the terminal performs blind detection by utilizing at least two pre-designated load sizes so as to receive scheduling information of SIB1 information sent by the transmission point.

The UE may blindly detect the payload sizes of SIB1 scheduling information corresponding to different downlink bandwidths, i.e. blindly detect ePDCCH corresponding to different bandwidths, where the ePDCCH is used to schedule SIB1 information, and after detection, the downlink bandwidth may be corresponding to the detected payload sizes of the ePDCCH, or the downlink bandwidth may also be indicated by the scheduling information of SIB1 and/or SIB1 information. For ePDCCH carried in SIB1 scheduling information, i.e. scheduling SIB1 information, any combination of redundancy bits or redundancy states in the ePDCCH, e.g. new data indication (New Data Indicator, NDI) bits, transmit power control (Transmit Power Control, TPC) bits or states, bits or states of HARQ process numbers may be employed.

Assuming that the PBCH carrying MIB information is not transmitted in the system, information in the MIB information may be carried in SIB1 information or a common downlink control channel for scheduling SIB1, for example, at least one of system radio frame number, downlink bandwidth, configuration information of enhanced PHICH, antenna port of UERS, scrambling code of UERS, and the like. For notification by scheduling the common downlink control channel of SIB1, it may be specifically indicated by a redundancy bit or state in the common downlink control channel, such as a new data indication (New Data Indicator, NDI) bit, a transmit power control (Transmit Power Control, TPC) bit or state, and any combination of bits or states of a hybrid automatic repeat (Hybrid Automatic Retransmission Request, HARQ) process number.

Specifically, the common control information is at least one of MIB information, control information of MIB information scheduling, SIB1 information and scheduling information of SIB1 information. Accordingly, the second resource may include at least one of virtual cell identification information, virtual radio network temporary identification information, and demodulation reference signal information of common scheduling information for scheduling at least one of SIB information, RACH response information, and paging information.

Specifically, the virtual cell identification information includes at least one virtual cell identification, the virtual cell identification is used for scrambling demodulation reference signals of the public scheduling information and/or information of the public scheduling information scheduling, and the information of the public scheduling information scheduling includes at least one of SIB information, random access channel (Random Access Channel, RACH) response information, paging information and group power control information.

For example, in a heterogeneous network scenario, a large number of microcells are deployed within the coverage of one macrocell, and these cells can obtain combining gain with the same physical cell identity, but since the same physical cell identity is adopted, the capacity of common control information (SIB information, paging information, RACH response information, group power control information, etc.) is limited, and thus these cells share the same common search space. The scheme of the application is that at least one of demodulation reference signal information of virtual cell identification information, virtual wireless network temporary identification information and public scheduling information is notified in MIB information or control information of MIB information scheduling or SIB1 information or scheduling information of SIB1 information.

The virtual cell identification information may be at least one virtual cell identification, or may be one virtual cell identification and at least one offset with respect to the virtual cell identification, and a plurality of virtual cell identifications may be obtained according to the offset, or may be at least one offset with respect to a physical cell identification, and a plurality of virtual cell identifications may be obtained according to the offset. The virtual cell identifies demodulation reference signals used for scrambling the common scheduling information and/or information scheduled by the common scheduling information, wherein the scheduled information comprises at least one of SIB information, RACH response information, paging information and group power control information. This allows independent configuration of common control information between the plurality of microcells and the macrocell and may interfere with randomization.

For the virtual radio network temporary identification information, virtual radio network temporary identification information corresponding to system information, paging information, RACH response information, and group power control information, respectively, may be used. The virtual wireless network temporary identifier information may be at least one virtual wireless network temporary identifier, or may be one virtual wireless network temporary identifier and at least one offset relative to the virtual wireless network temporary identifier, where a plurality of virtual wireless network temporary identifiers may be obtained according to the offset, or may be at least one offset relative to the wireless network temporary identifier, and a plurality of virtual wireless network temporary identifiers may be obtained according to the offset. The virtual wireless network temporary identification information is used to scramble Cyclic Redundancy Check (CRC) bits of the common scheduling information. This allows independent configuration of common control information between the plurality of microcells and the macrocell and may interfere with randomization.

For the demodulation reference signal information of the common scheduling information, at least one scrambling sequence of the demodulation reference signal of the common scheduling information may be used. The scrambling sequence is used to determine demodulation reference signals for common scheduling information.

Further, the terminal may further receive the common control information according to the second resource.

In this embodiment, different transmission points may select different first resources to implement interference avoidance of a common control channel, so as to avoid the problem in the prior art that a terminal in a cell corresponding to a micro base station may be interfered by a macro base station or other micro base stations, or a terminal in a cell corresponding to a macro base station may be interfered by a micro base station, so that the terminal may correctly receive common control information sent by the transmission point, thereby improving reliability of obtaining the common control information.

Furthermore, the application includes another embodiment:

specifically, the common control information is a synchronization signal. Accordingly, the second resource may be MIB information. Specifically, MIB information may be descrambled by a first sequence determined by a synchronization signal transmitted in a first synchronization channel.

Further, the terminal may further acquire a second sequence, and determine a time-frequency resource of the common search space and/or a resource of a second common control channel carrying scheduling information of SIB1 information through the second sequence. The terminal may further descramble the control channel and the data channel transmitted in the common search space through the second sequence. Specifically, the terminal may detect the second synchronization channel and determine the second sequence through the second synchronization channel, or the terminal may acquire the second sequence by reading MIB information. According to the scheme, MIB information and a public search space can be scrambled respectively through the synchronous signals, so that flexibility is improved, and interference randomization is optimized.

Specifically, the common control information is a synchronization signal. Accordingly, the second resource may then be a carrier type. The terminal may determine a carrier type of a current carrier from the first synchronization channel and the first reference signal.

Specifically, the terminal may determine the carrier type of the current carrier by jointly detecting the first reference signal and the synchronization signal transmitted in the first synchronization channel.

The first synchronization channel may be a synchronization channel of an LTE release 8 system, or a translated copy of the synchronization channel of the LTE release 8 system in time.

The first reference signal may be a cell-specific reference signal CRS of an LTE release 8 system, or may also be a part of a CRS of an LTE release 8 system, for example, the CRS of the LTE release 8 system is transmitted every 5 subframes, or may also be a reference signal for making Radio Resource Management (RRM) measurements, or may also be a reference signal for making time-frequency synchronization tracking.

The carrier type may be a carrier of a backward compatible LTE release 8 system, i.e. an LTE UE of release 8 may be allowed to access the carrier, or a carrier of a non-backward compatible LTE release 8 system, i.e. a new carrier type not allowed to be accessed by an LTE UE of release 8, where the specific characteristics of the new carrier type may be one or more of the following characteristics: the resource position of the PSS/SSS of the synchronous channel is changed compared with that of the PSS/SSS of the version 8 system; no control channel region, i.e., no PDCCH; the data scheduling applies ePDCCH, namely PDCCH which can be precoded; the CRS is transmitted only on a portion of the subframe and/or on a portion of the carrier bandwidth.

For example, assuming that the PSS/SSS of the new carrier type is a translated copy of the PSS/SSS of the backward compatible carrier, when the UE accesses the carrier, the type of the carrier cannot be identified simply by detecting the PSS/SSS, and further, it is necessary to continue blind detection of the possible positions of the CRS based on the detected positions of the PSS/SSS, where the possible positions are two, one corresponding to the backward compatible carrier and one corresponding to the new carrier type, so that the UE can determine the type of the current carrier by jointly detecting the PSS/SSS and the CRS.

Fig. 2 is a flowchart of a control information processing method according to another embodiment of the present application, as shown in fig. 2.

201. The transmission point determines at least one first resource of a first common control channel for the terminal.

202. And the transmission point sends common control information to the terminal through the first common control channel according to the at least one first resource.

Accordingly, in 202, the transmission point may specifically send common control information to the terminal on the determined one first resource through the first common control channel.

Specifically, in 201, the transmission point may specifically determine the first resource, for example, a protocol contract, for the terminal according to the pre-configured resource information. For example, the time domain position of the one first resource may be a fixed subframe number, e.g. subframe 0, the frequency domain position of the one first resource may be a fixed physical resource block (Physical Resource Block, PRB) or a PRB pair, e.g. the frequency domain position of the one first resource may also be within a frequency bandwidth of 6 PRB pairs of the carrier center.

Accordingly, in 202, the transmission point may specifically determine one first resource from the at least two first resources; and the transmission point sends common control information to the terminal through the first common control channel on the determined first resource.

Optionally, before 202, the transmission point may further send first indication information to the terminal, where the first indication information is used to indicate at least two first resources of the first common control channel, so that the terminal receives, according to the first indication information, common control information sent by the transmission point through the first common control channel. Specifically, the transmission point may specifically send the first indication information to the terminal through a synchronization channel, a higher layer signaling or a control channel.

As another example, the control channel may be a physical downlink control channel (Physical Downlink Control Channel, PDCCH) or an Enhanced PDCCH (ePDCCH), the latter demodulated based on UERS, the former demodulated based on a common reference signal (Common Reference Signal, CRS). Specifically, the transmission point may specifically send the first indication information to the terminal through a PDCCH, or may also send the first indication information to a group to which the terminal belongs through the PDCCH.

Optionally, after 201, the transmission point may further send second indication information to the terminal, where the second indication information is used to indicate one first resource in the at least one first resource, so that the terminal determines one first resource from the at least one first resource according to the second indication information.

Optionally, in a possible implementation manner of this embodiment, before 202, the transmission point may further determine a second resource for the terminal; correspondingly, the common control information, or the common control information and the cell identifier of the cell in which the terminal is located, are used by the terminal to determine the second resource.

For example, the common control information may include jointly encoded downlink bandwidth indication information and second resource indication information.

Specifically, the second resources included in the at least two second resources adopt a frequency hopping mode in the set, and parameters of the frequency hopping are determined by cell identification and time domain information, wherein the time domain information can be one or more of a frame number, a subframe number and a time slot number. The terminal may determine, according to the rule of frequency hopping, a time-frequency resource of the current common search space among the second resources included in the set. Therefore, the randomization effect of the time-frequency resource of the public search space on the frequency domain can be achieved, and the special channel of a certain terminal cannot be blocked greatly. Thus, the determined one second resource may be different in at least two subframes. In particular, the resource allocation of a group of public search spaces can be allocated to the terminal, and the resource allocation of different public search spaces in the group can be used on different subframes. The pattern of resource allocation of different common search spaces in the group may be directly notified to the terminal, or the terminal may be notified of the pattern of resource allocation of the common search spaces on sub-frames of the terminal, and then the terminal calculates the pattern of resource allocation of the common search spaces on other sub-frames based on a certain rule, which may be constructed based on one or more combinations of frame number, sub-frame number, slot number and cell identity.

Specifically, in the case where the common control information is MIB information or control information of MIB information scheduling or SIB1 information or scheduling information of SIB1 information. Accordingly, the second resource may include at least one of virtual cell identification information, virtual radio network temporary identification information, and demodulation reference signal information of common scheduling information for scheduling at least one of SIB information, RACH response information, and paging information.

Specifically, the virtual cell identification information includes at least one virtual cell identification, the virtual cell identification is used for scrambling demodulation reference signals of the public scheduling information and/or information scheduled by the public scheduling information, and the scheduled information includes at least one of SIB information, RACH response information, paging information and group power control information.

Furthermore, the application includes another embodiment:

specifically, the common control information is a synchronization signal. Accordingly, the second resource may be MIB information. According to the scheme, MIB information and a public search space can be scrambled respectively through the synchronous signals, so that flexibility is improved, and interference randomization is optimized.

Specifically, the common control information is a synchronization signal. Accordingly, the second resource may then be a carrier type. The carrier type may be a carrier of a backward compatible LTE release 8 system, i.e. an LTE UE of release 8 may be allowed to access the carrier, or a carrier of a non-backward compatible LTE release 8 system, i.e. a new carrier type not allowed to be accessed by an LTE UE of release 8, where the specific characteristics of the new carrier type may be one or more of the following characteristics: the resource position of the PSS/SSS of the synchronous channel is changed compared with that of the PSS/SSS of the version 8 system; no control channel region, i.e., no PDCCH; the data scheduling applies ePDCCH, namely PDCCH which can be precoded; the CRS is transmitted only on a portion of the subframe and/or on a portion of the carrier bandwidth.

Further, those skilled in the art will also appreciate that the embodiments described in the specification are all preferred embodiments, and that the acts and modules referred to are not necessarily required for the present application.

In the foregoing embodiments, the descriptions of the embodiments are emphasized, and for parts of one embodiment that are not described in detail, reference may be made to related descriptions of other embodiments.

Fig. 3 is a schematic structural diagram of a terminal according to another embodiment of the present application, and as shown in fig. 3, the terminal of this embodiment may include a determining unit 31 and a receiving unit 32. Wherein the determining unit 31 is configured to determine at least one first resource of a first common control channel; a receiving unit 32, configured to receive, according to the at least one first resource determined by the determining unit 31, common control information sent by a transmission point through the first common control channel.

Wherein the MIB information may include all or part of the MIB information in the current system, or may further include other information than the MIB information in the current system. The detailed description may be specifically referred to the related description in the corresponding embodiment of fig. 1, and will not be repeated herein.

Accordingly, the receiving unit 32 is specifically configured to

On the determined one first resource determined by the determining unit 31, common control information transmitted by the transmission point through the first common control channel is received.

Specifically, the determination unit 31 is specifically configured to

The one first resource, e.g. a protocol contract, is determined based on pre-configured resource information. For example, the time domain position of the one first resource may be a fixed subframe number, e.g. subframe 0, the frequency domain position of the one first resource may be a fixed physical resource block (Physical Resource Block, PRB) or a PRB pair, e.g. the frequency domain position of the one first resource may also be within a frequency bandwidth of 6 PRB pairs of the carrier center.

Accordingly, the receiving unit 32 is specifically configured to

Specifically, the determination unit 31 is specifically configured to

In particular, the receiving unit 32 is specifically configured to

Specifically, the receiving unit 32 may specifically receive the first indication information sent by the transmission point through a synchronization channel, a higher layer signaling, or a control channel.

Further, the one first resource determined by the receiving unit 32 is different in at least two subframes.

For example, the common control information is MIB information; the one first resource determined by the receiving unit 32 is different in at least two subframes, including:

Specifically, taking MIB information as an example (similar processing for scheduling information of SIB1 information), the same MIB information may be repeatedly transmitted a plurality of times over a plurality of subframes, for example, four times over four radio frames, each of which is transmitted once, the contents of the four times being the same, so as to obtain combining gain improvement performance. Assuming that MIB information of one cell is transmitted on the first two PRB pairs {0,1} of the 6 PRB pairs in the bandwidth center of the current downlink carrier, even if four combinations are available, if the two PRB pairs are in deep fading of the channel for a certain UE, the performance is poor, and even correct demodulation is not possible. In addition, the current MIB information has 4 symbols in 6 PRB pairs in the bandwidth center, so there is an influence on the resource mapping of the ePDCCH, that is, the ePDCCH with the PRB or PRB pair as the resource allocation granularity can occupy fewer resource units in each PRB pair in the 6 PRB pairs in the bandwidth center, which is also the reason that the ePDCCH in the LTE system of release 11 cannot transmit the ePDCCH on the PRB pair in which the MIB information is located. Therefore, a certain rule can be introduced to ensure that the MIB information repeatedly transmitted for four times occupies different frequency domain resource positions to obtain frequency domain diversity gain, and the demodulation performance of the MIB information can be improved by combining the four times of combining gain. For example, MIB information is transmitted N times in a first period, the N times of MIB information transmitted are identical, and N times of MIB information transmitted in a next first period may be changed; and, N times of MIB information in the first period are transmitted in the second period, and frequency domain resource patterns occupied by at least two transmissions of the N times of MIB information are different. Alternatively, the resource pattern of N times of transmission of MIB information in one first period is repeated in each first period, i.e., the resource positions of the above MIB information in a plurality of first periods are cyclic. The first period and the second period may be preconfigured or indicated by a cell identity. For example, the first period is 40 milliseconds and the second period is 10 milliseconds. The above N is equal to 4. For example, a preconfigured rule is adopted, or based on blind detection of the UE or based on indication of cell identification, so that PRB pairs occupied by MIB information of four repeated transmissions in one first period are {0,1}, {2,3}, {4,5} and {0,1}, respectively, and four transmissions in other first periods are repetitions of the above resource pattern. Of course, other resource distribution rules are not excluded nor are other minimum resource granularities excluded, e.g. four different resource patterns in PRB pairs, ecces or eregs. In this embodiment, different transmission points may select different first resources to implement interference avoidance of a common control channel, so as to avoid the problem in the prior art that a terminal in a cell corresponding to a micro base station may be interfered by a macro base station or other micro base stations due to multiplexing of time-frequency resources, or a terminal in a cell corresponding to a macro base station may be interfered by a micro base station, so that the terminal may correctly receive common control information sent by the transmission point. In addition, the MIB information is used for resource mapping in PRB or PRB pair units, for example, MIB information may occupy all symbols on 1 or 2 PRB pairs or all symbols except for symbols occupied by the synchronization signal, so that there is no influence on the resource mapping of ePDCCH, and therefore ePDCCH may not be used for MIB information mapping on the same PRB pair, and resource utilization is improved. In addition, although the frequency domain bandwidth occupied by the transmission of the MIB information at a time is reduced compared with the bandwidth of the previous 6 PRB pairs, the scheme of the present application can realize that the frequency domain resources occupied by the MIB information transmitted by a plurality of subframes are different to obtain the frequency domain diversity gain, and in addition, the different frequency domain resources can also carry other information, such as part of the information of the system radio frame number, the information of the antenna ports, and the like.
