Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method for configuring frequency domain resources and a base station.
Background
For the EMTC (enhanced machine Type communication) technology of the LTE (Long Term Evolution) network, currently, in the process of randomly accessing an EMTC cell in the LTE network by some terminals, in the prior art, there is a deviation in understanding the parameter configuration of the randomly accessed PUCCH frequency domain resource information of the PUCCH (Physical Uplink Control Channel).
The EMTC technology includes a CE (Channel Element) mode A, CE mode B two transmission modes, and the CEMode a includes two access classes, namely a CE level 0 and a CE level 1, where the CE mode a includes two access classes, namely a CE level 0 and a CE level 1, and the CE mode B includes two access classes, namely a CE level 2 and a CE level 3. For two access levels, namely, CE level 0 and CE level 1, included in CE mode A, the base station configures different PUCCH dynamic frequency domain resources for each access level.
The process of randomly accessing the EMTC cell in the LTE network by the terminal is to select a CE level of a PRACH (Physical Random access channel) according to RSRP (Reference signal receiving Power), and the base station configures frequency domain resources according to the CE level carried in a Random access request (for example, sent by MSG 1) at the terminal side. The n1PUCCH-AN-InfoList-R13 information in the protocol PUCCH-ConfigCommon-v1310 field of version R13 of 3GPP (3rd Generation Partnership Project) 36.331, 36.213 indicates the configuration of the frequency domain resources of the PUCCH. The frequency domain resource of PUCCH is used for ACK of MSG4 and ACK of HARQ. . At present, the base station has different configurations for the dynamic frequency domain resources of the PUCCH at CE level 0, CE level 1, CE level 2, and CE level 3, and 4 different pieces of field information are configured for the parameter n1PUCCH-AN-InfoList-r13 in the PUCCH at the 4 CE levels. That is, the base station configures different PUCCH frequency domain resources for two access classes included in the same CE mode
For example, for a terminal with an access level of CE level 0, the frequency domain resource indication information is configured for the terminal to be 40; for a terminal with an access level of CE level 1, configuring frequency domain resource indication information for the terminal to be 64; at this time, the indication information of the scheduled PUCCH frequency domain resource configured by the terminal with the access level CE level 0 is 40, and the actually scheduled PUCCH frequency domain resource of the terminal with the access level CE level 0 may not be the frequency domain resource of the configured indication information 40, for example, the actually scheduled PUCCH frequency domain resource is the frequency domain resource of the indication information 64, which may cause a failure in scheduling the frequency domain resource of the terminal with the access level CE level 0, so that the terminal cannot perform the random access to the EMTC cell in the LTE network. For example, part of terminals cannot well distinguish and use resources allocated under CE level 0 or CE level 1, which causes an exception to the MSG4ACK of the EMTC terminal, and thus cannot access the EMTC cell. The same situation occurs for both access levels in CE mode B, as well.
It can be seen that, in the process of randomly accessing an EMTC cell in an LTE network, for two different access classes in the same access mode, since frequency domain resources configured for a physical uplink control channel PUCCH of a terminal are different, a problem occurs that the terminal cannot randomly access the EMTC cell in the LTE network.

Detailed Description
In order to solve the technical problem, the technical scheme in the embodiment of the invention has the following general idea: a method and a base station for configuring frequency domain resources comprise the following steps: a base station receives a random access request sent by an Enhanced Machine Type Communication (EMTC) terminal when an EMTC cell stays in an LTE network, wherein the random access request carries a Channel Element (CE) mode; based on the random access request, the base station obtains a Channel Element (CE) mode carried in the random access request; when the CE mode is a first CE mode, a base station configures a first dynamic frequency domain resource for a Physical Uplink Control Channel (PUCCH) of the terminal, wherein an access grade included in the first CE mode is CE grade 0 or CE grade 1; and when the CE mode is a second CE mode, configuring a second dynamic frequency domain resource for a Physical Uplink Control Channel (PUCCH) of the terminal, wherein an access level included in the second CE mode is CE level 2 or CE level 3, the first dynamic frequency domain resource is different from the second dynamic frequency domain resource, the first dynamic frequency domain resource includes a plurality of frequency domain resources, and the second dynamic frequency domain resource includes a plurality of frequency domain resources different from the first dynamic frequency domain resource. That is to say, in the embodiment of the present invention, the base station obtains the CE mode in the random access request sent by the terminal, and the base station configures the same frequency domain resource for both of two different CE levels in the CE mode.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
As shown in fig. 1, a method for configuring frequency domain resources according to an embodiment of the present invention is applied to a base station, and includes:
s101, receiving a random access request sent by an Enhanced Machine Type Communication (EMTC) terminal when the EMTC terminal stays in an LTE network in an EMTC cell, wherein the random access request carries a Channel Element (CE) mode;
s102, based on the random access request, obtaining a Channel Element (CE) mode carried in the random access request;
s103, when the CE mode is a first CE mode, configuring a first dynamic frequency domain resource for a Physical Uplink Control Channel (PUCCH) of the terminal, wherein an access level included in the first CE mode is CE level 0 or CE level 1, and the first dynamic frequency domain resource includes a plurality of frequency domain resources.
The step S103 may specifically include:
and when the CE mode is a first CE mode, configuring a first dynamic frequency domain resource of which the frequency domain resource indication information is a first enumeration value for a random access PUCCH of the terminal. For example, when the CE mode is a first CE mode (regardless of whether the access level included in the mode is CE level 0 or CE level 1), the base station configures a PUCCH-n-InfoList-r 13 (indication information for characterizing frequency domain resources configured for the terminal by the base station) in a PUCCH-ConfigCommon-v1310 field (which is used for characterizing random access PUCCH frequency domain resource information) as a first enumerated value X; the value range of any value in the first enumerated value X is 0-2047, the specific value of X may be determined according to actual communication requirements, and the specific value of X may be multiple values in the range, for example, the value of X is {40, 41, … …, 63, 64} or {40, 64 }. That is, the base station configures, for the terminal, the first dynamic frequency domain resource whose frequency domain resource indication information is the first enumerated value.
As shown in fig. 2, after the step S102 is performed, the method may further include:
and S104, when the CE mode is a second CE mode, configuring a second dynamic frequency domain resource for a Physical Uplink Control Channel (PUCCH) of the terminal, wherein an access level included in the second CE mode is CE level 2 or CE level 3, and the second dynamic frequency domain resource includes a plurality of frequency domain resources different from the first dynamic frequency domain resource.
The step S104 may specifically include:
and when the CE mode is a second CE mode, configuring a second dynamic frequency domain resource of which the frequency domain resource indication information is a second enumerated value for a random access PUCCH of the terminal, wherein the first enumerated value and the second enumerated value are different. For example, when the CE mode is the second CE mode (regardless of whether the access class included in the mode is CE level 2 or CE level 3), the base station configures the PUCCH-ConfigCommon-v1310 field (which is used to characterize the random access PUCCH frequency domain resource information) with n1PUCCH-AN-InfoList-r13 (which is used to characterize the frequency domain resources configured for the terminal) as the second enumerated value Y. The specific value of Y is different from the specific value of X, that is, for a value where the first enumerated value X is already used in the range of 0 to 2047, the second enumerated value Y is not used, for example, the first enumerated value X is {40, 41, … …, 63, 64}, and the second enumerated value Y takes a value outside the set of {40, 41, … …, 63, 64 }. The value range of any value in the second enumerated value Y is also 0-2047, the specific value of Y may be determined according to actual communication requirements, and the specific value of Y may be one or more values in the range, for example, the value of Y is {65, 66, … …, 79, 80} or {66, 80 }. That is, the base station configures, for the terminal, the second dynamic frequency domain resource whose frequency domain resource indication information is the second enumerated value.
For better understanding of the present embodiment, the method for configuring frequency domain resources provided by the present embodiment is further illustrated as follows:
assuming that an EMTC terminal stays in an EMTC cell in an LTE network, the terminal sends a random access request to a base station, wherein the random access request carries a Channel Element (CE) mode;
the base station obtains the CE mode;
when the CE mode is CE mode a, the base station configures n1PUCCH-AN-InfoList-r13 in the PUCCH-ConfigCommon-v1310 field as a first enumerated value X, which is specifically 40 and 64, regardless of whether the access level included in CE mode a is CE level 0 or CE level 1.
Thus, when the access class included in CE mode a is CE class 0, configured for the terminal are the first dynamic frequency domain resources indicating information of 40 and 64; the base station returns acknowledgement information for the CE mode a to the terminal (e.g., sent via MSG 5); the terminal may schedule the configured first dynamic frequency domain resource according to its own needs.
When the access level included in the CE mode a is CE level 1, configuring a first dynamic frequency domain resource for the terminal, which is also the indication information of 40 and 64; the base station returns acknowledgement information for the CE mode a to the terminal (e.g., sent via MSG 5); the terminal may schedule the configured first dynamic frequency domain resource according to its own needs.
When the CE mode is CE mode B, the base station configures n1PUCCH-AN-InfoList-r13 in the PUCCH-ConfigCommon-v1310 field as a second enumerated value Y (different from the aforementioned X) regardless of whether the access level included in the CE mode B is CE level 2 or CE level 3, specifically {65, 66, … …, 79, 80 }.
Thus, when the access class included in CE mode B is CE class 2, the frequency domain resource configured for the terminal is the second dynamic frequency domain resource whose indication information is {65, 66, … …, 79, 80 }. The base station returns an acknowledgement for this CE mode B to the terminal (e.g., sent via MSG 5). The terminal may schedule the configured second dynamic frequency domain resource according to its own needs.
When the access class included in CE mode B is CE class 3, the frequency domain resource configured for the terminal is also the second dynamic frequency domain resource whose indication information is {65, 66, … …, 79, 80 }. The base station returns an acknowledgement for this CE mode B to the terminal (e.g., sent via MSG 5). The terminal may schedule the configured second dynamic frequency domain resource according to its own needs.
That is to say, the base station configures the same first random access PUCCH frequency domain resources for two access levels CE level 0 and CE level 1 in CE mode a; and the base station configures the same second random access PUCCH frequency domain resources for two access levels CE level 2 and CE level 3 in the CE mode B (the second random access PUCCH frequency domain resources are different from the first random access PUCCH frequency domain resources). The base station well realizes compatibility processing of the abnormal terminal by optimizing the distribution of PUCCH frequency domain resources in the CE mode, and improves the fault tolerance of the base station.
As shown in fig. 3, a second embodiment of the present invention provides a base station, including:
a receiving module 301, configured to receive a random access request sent by an EMTC terminal in an LTE network when the EMTC terminal stays in an EMTC cell, where the random access request carries a channel element CE mode;
a first obtaining module 302, configured to obtain, based on the random access request, a channel element CE mode carried in the random access request;
a first configuring module 303, configured to configure a first dynamic frequency domain resource for a physical uplink control channel, PUCCH, of the terminal when the CE mode is a first CE mode, where an access level included in the first CE mode is CE level 0 or CE level 1, and the first dynamic frequency domain resource includes multiple frequency domain resources.
Further, the first configuring module 303 is specifically configured to configure, for the random access PUCCH of the terminal, a first dynamic frequency domain resource whose frequency domain resource indication information is a first enumerated value. For example, when the CE mode is the first CE mode (regardless of whether the access level included in the mode is CE level 0 or CE level 1), the first configuration module 303 configures a PUCCH-ConfigCommon-v1310 field (which is used to characterize random access PUCCH frequency domain resource information) with n1PUCCH-AN-InfoList-r13 (which is used to characterize frequency domain resources configured for the terminal) as a first enumerated value X; the value range of any value in the first enumerated value X is 0-2047, the specific value of X may be determined according to actual communication requirements, and the specific value of X may be multiple values in the range, for example, the value of X is {40, 41, … …, 63, 64} or {40, 64 }. That is, the first configuration module 303 configures the terminal with the first dynamic frequency domain resource whose frequency domain resource indication information is the first enumerated value.
As shown in fig. 4, the base station further includes a second configuring module 304, after the first obtaining module 302 obtains the channel element CE pattern carried in the random access request based on the random access request,
the second configuring module 304 is configured to configure a second dynamic frequency domain resource for a physical uplink control channel, PUCCH, of the terminal when the CE mode is a second CE mode, where an access level included in the second CE mode is CE level 2 or CE level 3, and the first dynamic frequency domain resource is different from the second dynamic frequency domain resource.
Further, the second configuring module 304 is specifically configured to, when the CE mode is a second CE mode, configure a second dynamic frequency domain resource whose frequency domain resource indication information is a second enumerated value for a random access PUCCH of the terminal, where the first enumerated value and the second enumerated value are different, and the second dynamic frequency domain resource includes a plurality of frequency domain resources different from the first dynamic frequency domain resource. For example, when the CE mode is the second CE mode (regardless of whether the access level included in the mode is CE level 0 or CE level 1), the second configuring module 304 configures PUCCH-ConfigCommon-v1310 field (which is used to characterize random access PUCCH frequency domain resource information) with n1PUCCH-AN-InfoList-r13 (which is used to characterize frequency domain resources configured for the terminal) as the second enumerated value Y. The specific value of Y is different from the specific value of X, that is, for a value where the first enumerated value X is already used in the range of 0 to 2047, the second enumerated value Y is not used, for example, the first enumerated value X is {40, 41, … …, 63, 64}, and the second enumerated value Y takes a value outside the set of {40, 41, … …, 63, 64 }. The value range of any value in the second enumerated value Y is also 0-2047, the specific value of Y may be determined according to actual communication requirements, and the specific value of Y may be one or more values in the range, for example, the value of Y is {65, 66, … …, 79, 80} or {66, 80 }. That is, the second configuration module 304 configures the terminal with the second dynamic frequency-domain resource whose frequency-domain resource indication information is the second enumerated value.
For better understanding of the present embodiment, the base station provided in the present embodiment is further exemplified, and the base station includes a receiving module 301, a first obtaining module 302, a first configuring module 303, and a second configuring module 304:
assuming that a terminal stays in an EMTC cell in an LTE network, the terminal sends a random access request to a receiving module 301 in a base station, where the random access request carries a channel element CE mode;
the first obtaining module 302 obtains the CE mode;
when the CE mode is CE mode a, the first configuration module 303 configures the PUCCH-AN-InfoList-r13 in the PUCCH-ConfigCommon-v1310 field as the first enumerated value X, which is 40 or 64, regardless of whether the access level included in the CE mode a is CE level 0 or CE level 1.
In this way, when the access level included in the CE mode a is CE level 0, the first configuration module 303 configures, for the terminal, the first dynamic frequency domain resource whose indication information is 40 and 64; the base station returns acknowledgement information for the CE mode a to the terminal (e.g., sent via MSG 5); the terminal may schedule the configured first dynamic frequency domain resource according to its own needs.
When the access level included in the CE mode a is CE level 1, the first configuration module 303 configures, for the terminal, the first dynamic frequency domain resource also indicating that the information is 40 and 64; the base station returns acknowledgement information for the CE mode a to the terminal (e.g., sent via MSG 5); the terminal may schedule the configured first dynamic frequency domain resource according to its own needs.
When the CE mode is CE mode B, the second configuring module 304 configures the n1PUCCH-AN-InfoList-r13 in the PUCCH-ConfigCommon-v1310 field as a second enumerated value Y (different from the aforementioned X) regardless of whether the access level included in the CE mode B is CE level 2 or CE level 3, where Y is {65, 66, … …, 79, 80 }.
Thus, when the access class included in CE mode B is CE class 2, the frequency domain resource configured for the terminal by the second configuration module 304 is, for example, a second dynamic frequency domain resource whose indication information is {65, 66, … …, 79, 80 }. The base station returns an acknowledgement for this CE mode B to the terminal (e.g., sent via MSG 5). The terminal may schedule the configured second dynamic frequency domain resource according to its own needs.
When the access class included in CE mode B is CE class 3, the frequency domain resource configured by the second configuration module 304 for the terminal is also the second dynamic frequency domain resource whose indication information is {65, 66, … …, 79, 80 }. The base station returns an acknowledgement for this CE mode B to the terminal (e.g., sent via MSG 5). The terminal may schedule the configured second dynamic frequency domain resource according to its own needs.
That is to say, the base station configures the same first random access PUCCH frequency domain resources for two access levels CE level 0 and CE level 1 in CE mode a; and the base station configures the same second random access PUCCH frequency domain resources for two access levels CE level 2 and CE level 3 in the CE mode B (the second random access PUCCH frequency domain resources are different from the first random access PUCCH frequency domain resources). The base station well realizes compatibility processing of the abnormal terminal by optimizing the distribution of PUCCH frequency domain resources in the CE mode, and improves the fault tolerance of the base station.
A third embodiment of the present invention provides a computer apparatus, which includes a processor, and the processor is configured to implement the steps of the method according to the first embodiment when executing the computer program stored in the memory.
A fourth embodiment of the present invention provides a computer-readable storage medium, on which a computer program is stored, where the computer program, when executed by a processor, implements the steps of the method as described in the first embodiment.
