Description
Technical Field
The present invention relates to the field of communications, and in particular, to a resource allocation method and a network device.
Background
The LTE (Long Term Evolution) technology supports two duplex modes, FDD (frequency division duplex) and tdd (time division duplex). The TDD mode refers to the transmission of uplink and downlink signals at different moments by using the same working frequency band by uplink and downlink; the FDD mode means that the uplink and downlink use different operating frequency bands, and uplink and downlink signals can be transmitted on different frequency carriers at the same time.
In the LTE system, one radio frame in FDD mode and TDD mode has a length of 10ms, and includes 10 subframes with a length of 1ms, i.e., 1 ms.
For a radio frame in a TDD mode, different TDD uplink and downlink subframe configurations are defined, and specifically, as shown in table 1, D represents a downlink subframe, U represents an uplink subframe, S represents a special subframe, and each configuration sequence number corresponds to one uplink and downlink subframe configuration.
TABLE 1
As can be seen from table 1, the uplink and downlink timeslot configurations of the existing TDD system are determined in advance and cannot be changed. Taking the configuration sequence number of 5ms repetition as an example, the downlink-uplink-downlink repeated transmission switching is usually involved. Meanwhile, the length setting of GP (guard interval, a kind of special subframe S, located between an uplink subframe and a downlink subframe) cannot be adjusted according to actual requirements, so that the problem of transmission interference between base stations due to insufficient GP length often occurs.
In view of the above, for TDD communication systems, including but not limited to 5G systems, it is necessary to consider introducing a new frame structure configuration to improve the flexibility of TDD configuration.

Wherein the notification signaling comprises two or more first transmission transition periods.
The second transmission switching period configured by the target cell to the mobile communication terminal is the same as the first transmission switching period, and the quantity of the downlink transmission resources in each second transmission switching period is less than or equal to the first upper limit of the corresponding first transmission switching period, and the quantity of the uplink transmission resources in each second transmission switching period is less than or equal to the second upper limit of the corresponding first transmission switching period.

The scheme of the invention has the following beneficial effects:
the scheme of the invention only configures the upper limit of the uplink and downlink transmission resources in the conversion period, and can flexibly adjust the uplink transmission resource occupation ratio and the downlink transmission resource occupation ratio in the conversion period according to the transmission requirement on the premise of not exceeding the upper limit. For example, the base station configures a first upper limit of a transmission resource for downlink transmission and a second upper limit of a transmission resource for uplink transmission in the transition period on the premise of ensuring that the GP length in the transition period is long enough to avoid generating no interference with the neighboring base station, and informs the neighboring base station to achieve coexistence. Based on the limitation of the first upper limit and the second upper limit, the finally determined time slot structure of the switching period can effectively avoid transmission interference between the base stations.

Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments. In the following description, specific details such as specific configurations and components are provided only to help the full understanding of the embodiments of the present invention. Thus, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
The invention provides a solution to the problem that the subframe structure of the existing transmission and conversion cycle is fixed and flexible configuration cannot be realized based on the network condition.
In one aspect, an embodiment of the present invention provides a resource allocation method, as shown in fig. 1, including:
step 101, sending a notification signaling to a neighboring base station, where the notification signaling is used to indicate: the target cell uses at least one first transmission switching period, and a first upper limit of transmission resources for downlink transmission and a second upper limit of transmission resources for uplink transmission in each first transmission switching period.
The resource allocation method of this embodiment only allocates the upper limit of the uplink and downlink transmission resources in the conversion period, and on the premise that the upper limit is not exceeded, the uplink transmission resource proportion and the downlink transmission resource proportion in the conversion period can be flexibly adjusted according to the transmission requirement. For example, the base station configures a first upper limit of a transmission resource for downlink transmission and a second upper limit of a transmission resource for uplink transmission in the transition period on the premise of ensuring that the GP length in the transition period is long enough to avoid generating no interference with the neighboring base station, and informs the neighboring base station to achieve coexistence. Based on the limitation of the first upper limit and the second upper limit, the finally determined time slot structure of the switching period can effectively avoid transmission interference between the base stations.
Further, when the occupation proportion of the uplink transmission resource and the occupation proportion of the downlink transmission resource in the conversion period are specifically determined based on the limitations of the first upper limit and the second upper limit, flexible setting can be further performed according to the actual uplink and downlink transmission data volume. For example, if the amount of data currently transmitted in downlink is greater than the amount of data currently transmitted in uplink, the occupation ratio of the downlink transmission resources in the conversion period may be controlled to be greater than the occupation ratio of the uplink transmission resources in the conversion period, so as to more effectively utilize the network transmission resources and ensure the data transmission efficiency.
It should be noted that, the first upper limit may be regarded as a maximum proportion of the total resources of the first transmission switching period occupied by the downlink transmission resources, and therefore, in practical applications, the first upper limit may be a maximum number of downlink transmission units (time slots, symbols, and the like that the downlink transmission units can transmit uplink) in the first transmission switching period, and may also be a maximum occupied time of downlink transmission in the first transmission switching period. Similarly, the second upper limit may be regarded as a maximum ratio of the uplink transmission resource to the total resource of the first transmission conversion period, and therefore, in practical applications, the second upper limit may be a maximum number of uplink transmission units (time slots, symbols, and the like that the uplink transmission units may transmit uplink) in the first transmission conversion period, or may be a maximum occupation time of uplink transmission in the first transmission conversion period.
In addition, if the first upper limit and the second upper limit of this embodiment are respectively used to limit the maximum number of the downlink transmission units in the first transmission conversion period and the maximum number of the uplink transmission units in the first transmission conversion period, the lengths corresponding to each downlink transmission unit and each uplink transmission unit are not unique, and the setting can be flexibly performed. That is, the scheme of this embodiment does not limit the granularity of transmitting the uplink data and transmitting the downlink data in the transmission switching period.
Further, after the base stations inform each other of the restriction of the transmission switching period used by the target cell, the target cell further needs to configure a second transmission switching period, which is finally applied to data transmission, for the communication terminal under the condition that the restriction of the first upper limit and the second upper limit is met.
It should be noted that, in practical applications, data interaction between the target cell and the mobile communication terminal may consume several second transmission switching periods. In the data interaction process, the data interaction process may be a second transmission conversion period repetition cycle, or may be no less than two second transmission conversion periods repetition cycles.
For the notification signaling, the first transmission switching period indicated by the notification signaling needs to correspond to the second transmission switching period one by one. That is, there are several second transmission switching periods required for transmitting data, and several first transmission switching periods need to be set in the notification signaling. The downlink transmission resource quantity and the uplink transmission resource quantity in the second transmission conversion period are respectively restricted by a first upper limit and a second upper limit in a corresponding first transmission conversion period in the notification signaling.
And the upper limit requirements of the quantity of the downlink transmission resources and/or the upper limit requirements of the quantity of the uplink transmission resources corresponding to different types of second transmission conversion periods are different. Therefore, when the target cell and the mobile communication terminal need to use at least two second transmission switching cycles, the signaling is notified that the first upper limits corresponding to the at least two first transmission switching cycles are different, and/or the second upper limits corresponding to the at least two first transmission switching cycles are different.
Taking the example that the data interaction process between the target cell and the communication terminal is only composed of one transmission switching cycle, the second notification signaling only includes one first transmission switching cycle:
the second transmission switching period configured by the target cell to the mobile communication terminal is the same as the first transmission switching period, the number of downlink transmission resources in the second transmission switching period is less than or equal to a first upper limit, and the number of uplink transmission resources in the second transmission switching period is less than or equal to a second upper limit.
That is, the notification signaling between base stations indicates as follows: the duration of the uplink and downlink transmission conversion period is T (the duration of T is not unique and may be set according to the use requirement), the upper limit of the downlink transmission resource in the period is K time slots (the upper limit of the downlink transmission resource may also be limited by symbols, such as L symbols, the upper limit of the downlink transmission resource may also be limited by time slots and symbols, such as D time slots and C symbols), the upper limit of the uplink transmission resource is M time slots (the upper limit of the uplink transmission resource may also be limited by symbols, such as N symbols, the upper limit of the uplink transmission resource may also be limited by time slots and symbols, such as a time slots and B symbols), where K, L, M, N, D, C, A and B are both non-negative integers.
Correspondingly, the target cell, based on the notification signaling indication, needs to configure the uplink and downlink switching cycle for the communication terminal, which is the same as the time length of the switching cycle interacted in the notification signaling, and is T; the maximum number of downlink resources can not exceed the downlink resource upper limit for informing signaling interaction, namely the downlink resources do not exceed a set of K time slots or L symbols or D time slots and C symbols; and the maximum number of the uplink resources can not exceed the uplink resource upper limit for informing signaling interaction, namely the uplink resources do not exceed the set of M time slots or N symbols or A time slot and B symbols.
By way of exemplary introduction, assuming that the notification signaling indicates that the duration of the first transmission switching period is 5ms, a first upper limit of the number of downlink transmission slots is defined as 4, a second upper limit of the number of uplink transmission slots is defined as 3, and the transmission unit is a slot.
As shown in fig. 2, the target cell configures, according to the indication of the notification signaling, a second switching period 200 for the communication terminal, which includes 4 downlink transmission time slots DL, 2 uplink transmission time slots UL, and the remaining undefined transmission time slots un-known (the undefined subframe may be used as GP).
Based on the frame structure shown in fig. 2, in the second conversion period 200, the timeslot arrangement sequence is a downlink transmission timeslot DL, an undefined transmission timeslot, and an uplink transmission timeslot in turn. Since the total number of timeslots in the second switching cycle 200 is determined, the communication terminal can specifically determine which timeslots are used for uplink transmission and which timeslots are used for downlink transmission in the second switching cycle only based on the arrangement sequence and the number of uplink and downlink transmission timeslots.
Of course, the ordered sorting of the timeslots in the second switching period according to categories is only used for exemplary description, and as another feasible scheme, an undefined transmission timeslot may be arranged in front of the downlink transmission timeslot and the uplink transmission timeslot, and the ordered sorting may be predetermined by a protocol, and the communication terminal and the target cell may be directly applied.
Further, the slots of the second switching cycle may not be ordered by slot type. That is, the downlink transmission slots, undefined transmission slots, and uplink transmission slots in the second conversion period may be arranged alternately. For the frame structure design of the interspersing arrangement mode, the target cell can inform the communication terminal of the position information of at least two of the downlink transmission time slot, the undefined transmission time slot and the uplink transmission time slot in the second conversion period through message signaling, so that the communication terminal can specifically determine which time slots are used for uplink transmission and which time slots are used for downlink transmission in the second conversion period based on the position information.
By comparison, it can be seen that: if the time slots of the second conversion period are orderly arranged according to the categories, the terminal only needs to perform transmission conversion from downlink to uplink once in one second conversion period; if the time slots of the second conversion period are arranged alternately according to the category, more various frame structure configurations can be realized.
Of course, the first upper limit and the second upper limit in the above notification signaling are described by taking the number of time slots as an example. As another feasible solution, the first upper limit and the second upper limit of this embodiment may also be a ratio that the downlink transmission resource occupies the second conversion period and a ratio that the uplink transmission resource occupies the second conversion period, respectively.
That is, as shown in fig. 3, the notification information indicates: there is a first transmission transition period. The horizontal length represents time, the duration of the first transmission switching period 300 is T, the upper limit of the downlink transmission resource occupies T by X, and the uplink transmission resource occupies T by Y.
Correspondingly, there are four possibilities for the second transmission switching period configured by the target cell for the communication terminal:
a second transmission switching period 301, in which the occupation of the downlink transmission resource reaches the maximum upper limit X and the occupation of the uplink transmission resource is less than the maximum upper limit Y;
a second transmission switching period 302 in which the occupation of the downlink transmission resource is smaller than the maximum upper limit X and the occupation of the uplink transmission resource reaches the maximum upper limit Y;
a second transmission switching period 303, in which the occupation of the downlink transmission resources is smaller than the maximum upper limit X, and the occupation of the uplink transmission resources is smaller than the maximum upper limit Y;
in the second transmission switching period 303, the occupation of the downlink transmission resource reaches the maximum upper limit X, and the occupation of the uplink transmission resource reaches the maximum upper limit Y.
As can be seen from fig. 3, the downlink resource of the second transmission switching period finally configured by the target cell for the communication terminal is a subset or a full set of the first upper limit corresponding to the first transmission switching period in the notification signaling. Similarly, the uplink resource of the second transmission switching period finally configured by the target cell for the communication terminal is a subset or a full set of the second upper limit corresponding to the first transmission switching period in the notification signaling.
In practical application, if a second transmission conversion period is configured according to the resource proportion, the finally determined second transmission conversion period may be arranged according to the sequence of the downlink transmission resource, the undefined transmission resource and the uplink transmission resource; the target cell informs the communication terminal of the occupation ratio of the downlink transmission resource and the occupation ratio of the uplink transmission resource through message signaling, so that the communication terminal can determine which time slots are used for downlink transmission and which time slots are used for uplink transmission in the second transmission conversion period. Or the downlink transmission resources, the undefined transmission resources, and the uplink transmission resources of the second transmission switching period may also be arranged alternately, and the target cell informs the communication terminal of the location information of at least two of the downlink transmission resources, the undefined transmission resources, and the uplink transmission resources in the second transmission switching period through a message signaling, so that the communication terminal specifically determines which timeslots are used for uplink transmission and which timeslots are used for downlink transmission in the second switching period based on the location information.
In addition, taking an example that the data interaction process between the target cell and the communication terminal is formed by two or two kinds of second transmission switching cycles in a repeating cycle, the notification signaling includes two or more than two first transmission switching cycles (the first transmission switching cycles and the second transmission switching cycles correspond to each other one by one).
The second transmission switching period configured by the target cell to the mobile communication terminal is the same as the first transmission switching period, and the quantity of the downlink transmission resources in each second transmission switching period is less than or equal to the first upper limit of the corresponding first transmission switching period, and the quantity of the uplink transmission resources in each second transmission switching period is less than or equal to the second upper limit of the corresponding first transmission switching period.
For example, assuming that the data interaction process between the target cell and the communication terminal includes two types of second transmission switching cycles (the principle of the two or more types of second transmission switching cycles is the same, and description is omitted for example), the notification signaling between the base stations indicates as follows: there are two first transmission transition periods in succession.
Wherein, the duration of the uplink and downlink switching period of the first transmission switching period is T1(T1The duration of the downlink transmission is not unique and can be set according to the use requirement), the upper limit of the downlink transmission resource is K1One time slot (the upper limit of the downlink transmission resource can also be calculated in symbols, such as L1The upper limit of the individual symbols, downlink transmission resources, can also be calculated in time slots and symbols, e.g. D1A time slot and C1One symbol), the uplink transmission resource is limited to M1One time slot (the upper limit of the uplink transmission resource can also be calculated by a symbol, such as N1The individual symbol, uplink transmission resource upper limit can also be calculated in time slot and symbol, such as A1A time slot and B1Symbol), K1、L1、M1、N1、D1、C1、A1And B1Are all non-negative integers;
the duration of the uplink and downlink switching period of the second first transmission switching period is T2(T2The duration of the downlink transmission is not unique and can be set according to the use requirement), the upper limit of the downlink transmission resource is K2One time slot (the upper limit of the downlink transmission resource can also be calculated in symbols, such as L2The upper limit of the individual symbols, downlink transmission resources, can also be calculated in time slots and symbols, e.g. D2A time slot and C2One symbol), the uplink transmission resource is limited to M2One time slot (the upper limit of the uplink transmission resource can also be calculated by a symbol, such as N2The individual symbol, uplink transmission resource upper limit can also be calculated in time slot and symbol, such as A2A time slot and B2One symbol); k2，L2，M2、N2、D2，C2，A2And B2Are all non-negative integers, and K2，L2，M2、N2、D2，C2，A2And B2And the value of at least one parameter of the group K1、L1、M1、N1、D1、C1、A1And B1The corresponding values are the same.
For the target cell, the uplink and downlink switching period configured for the communication terminal is the same as the switching period interacted in the notification signaling, and the switching period comprises a time length T1The first and second transmission switching periods and duration of T2Second transmission switching period.
In the first and second transmission switching period, the maximum number of downlink resources can not exceed the upper limit indicated by the notification signaling, namely K1One time slot (or L)1A symbol or D1A time slot and C1One symbol); the maximum number of uplink resources cannot exceed the upper limit indicated by the notification signalling, i.e. M1A time slot (or N)1A symbol or A1A time slot and B1One symbol).
In the second transmission switching period, the maximum number of downlink resources can not exceed the upper limit indicated by the notification signaling, namely K2One time slot (or L)2A symbol or D2A time slot and C2One symbol); the maximum number of uplink resources cannot exceed the upper limit indicated by the notification signalling, i.e. M2A time slot (or N)2A symbol or A2A time slot and B2One symbol).
By way of exemplary introduction, it is assumed that the first transmission unit represents a downlink transmission slot and the second transmission unit represents a downlink transmission slot. The structure of the first second transmission switching period 401 and the second transmission switching period 402 that the target cell may finally configure for the communication terminal based on the indication of the notification signaling is shown in fig. 4: the duration of the second transmission switching period 401 and the duration of the second transmission switching period 402 are both 1 ms; the number of downlink transmission time slots DL and the number of uplink transmission time slots UL of one second transmission switching period 401 are 3, and the rest are undefined transmission time slots undown; the number of downlink transmission time slots DL and the number of uplink transmission time slots UL of another second transmission switching period 402 are 2, and the rest are undefined transmission time slots un-known.
After the second transmission switching periods 401 and 402 are configured in the target cell, the communication terminal is notified to perform application, so that the communication terminal continuously and repeatedly circulates the second transmission switching periods 401 and 402 in the time dimension to perform data transmission.
In practical applications, the time slots in the second transmission switching cycles 401 and 402 may also be ordered and sorted according to categories, that is, the target cell only needs to notify the communication terminal of the number of downlink time slots and the number of uplink time slots in the second transmission switching cycles 401 and 402, so that the communication terminal determines the specific frame structures of the second transmission switching cycles 401 and 402. Or the time slots in the second transmission switching cycles 401 and 402 may not be ordered according to the type of the time slots, the target cell needs to notify the communication terminal of the location information of at least two of the downlink transmission time slots, the undefined time slots, and the uplink transmission time slots in the second transmission switching cycles 401 and 402, so that the communication terminal determines the specific frame structures of the second transmission switching cycles 401 and 402.
Of course, the first upper limit and the second upper limit in the notification signaling with two or more first transition periods may also be the ratio of the downlink transmission resource occupying the transition period and the ratio of the uplink transmission resource occupying the transition period, respectively, and the principle is introduced above, so the description is omitted here for example.
The above is an explanation of the resource allocation method of the present embodiment. It should be noted that the present embodiment is not limited to the duration of the first transmission switching period and the second transmission switching period.
