Referring to
transmitting resource indication information to a device at a receiving side, where the resource indication information is used to indicate the device at the receiving side to determine, from consecutive time-domain resources repeated in a first periodicity and corresponding to a full configuration mode, a part or all of the time-domain resources as radio transmission resources for the device at the receiving side to interact with the network-side device.
Thus, based on the method for resource indication of the embodiment of the present disclosure, by transmitting the resource indication information to the device at the receiving side, a device at the receiving side can determine a part or all of the time-domain resources, from the consecutive time-domain resources, as the radio transmission resources, and the selected radio transmission resources may be either discretely distributed or continuously distributed from the consecutive time-domain resources, thereby achieving a flexible resource allocation.
Architecture of a typical mobile communication system in related art is as shown in
Certainly, there may also be another case that the relay base station interacts with the primary base station through the first part of the consecutive time-domain resources, and interacts with the terminal through the second part of the consecutive time-domain resources, while the primary base station interacts with the terminal though a third part of the consecutive time-domain resources.
If the relay base station interacts with the primary base station and the terminal simultaneously by using all of the consecutive time-domain resources, and receiving and transmitting data at same time in certain subframes may be expected. For example, Physical Downlink Control Channel (PDCCH) information from a Donor base station (primary base station) requires to be listened and to be forwarded both in a subframe header, which adversely affects transmission quality. Alternatively, both the primary base station and the relay base station transmit synchronization signals at a same location in a subframe, which adversely affects synchronization of the relay base station and detection of synchronization signal for the terminal. However, according to the method of the embodiments of the present disclosure, the above problems may be avoided, and transmission quality may be increased.
Furthermore, for a general network architecture, “Almost Blank Subframes (ABS)” may be formed in the time-domain resources by using the method of the embodiments of the present disclosure, to implement better interference elimination in a system with a high interference elimination requirement.
In the embodiments of the present disclosure, the resource indication information may be used to indicate quantity information and location information related to the radio transmission resources. It should be noted that, the quantity information and location information related to the radio transmission resources may not be necessarily included in the resource indication information, but must be indicated by the resource indication information.
The resource indication information may include segmentation information, starting point information and/or ending point information, which are used to indicate the quantity information and the location information related to the radio transmission resources.
The radio transmission resources may be either discretely distributed or continuously distributed in the consecutive time-domain resources, and thus a manner for indicating the radio transmission resources will be described hereinafter from both discrete distribution and continue distribution perspective, respectively.
(1) Radio Transmission Resources are Discretely Distributed in the Time Domain.
In the case that the radio transmission resources are discretely distributed in the time domain, there may be several manners for indicating radio transmission resource distribution in the time domain, for example, a first manner, a second manner and a third manner.
The First Manner
In the first manner, radio transmission resources are evenly segmented in the time domain. The resource indication information may include segmentation information and starting point information.
For instance, referring to
For another instance, referring to
The Second Manner
In the second manner, radio transmission resources are unevenly segmented in the time domain. The resource indication information may include segmentation information and starting point information.
For instance, referring to
The Third Manner
In the third manner, radio transmission resources are unevenly segmented in the time domain. The resource indication information may include starting point information and ending point information.
For instance, referring to
(2) Radio Transmission Resources are Continuously Distributed in the Time Domain.
In the case that the radio transmission resources are continuously distributed in the time domain, there may be several manners for indicating radio transmission resource distribution in the time domain, for example, a first mode, a second mode, and a third mode described below.
The First Mode
In the first mode, the starting point or the ending point may be default, and the resource indication information may only include segmentation information.
For instance, referring to
Parameter design can be simplified in the first mode, as only one parameter is needed.
The Second Mode
In the second mode, the resource indication information may include segmentation information and starting point information (or ending point information).
For instance, referring to
In the first mode, any continuous part of the time-domain resources may be assigned flexibly, thereby improving the flexibility of resource allocation.
It should be noted that, each of the above basic time scheduling units may be a basic time scheduling unit in the time domain, for example, a transmission time interval (TTI), or the smallest time scheduling unit (an OFDM symbol), or other time-domain units larger or smaller than the TTI in LTE system in related art, which are not limited in the present disclosure.
In terms of data included in the above resource indication information, when the radio transmission resources are discretely distributed in the time domain, the resource indication information may at least include more than three fields. The more segments which the radio transmission resources are segmented into are, the more fields included in the resource indication information are. While the radio transmission resources are continuously distributed in the time domain, only two fields may be enough to indicate the number and distribution of the radio transmission resources. Therefore, compared with the case that the radio transmission resources are discretely distributed in the time domain, the system overhead may be reduced in a case that the radio transmission resources are continuously distributed in the time domain.
Therefore, in order to reduce the system overhead, it's preferred that the radio transmission resources are continuously distributed in the time domain in the embodiments of the present disclosure.
In the case that the radio transmission resources are continuously distributed in the time domain, the resource indication may be only the offset of a starting point of the radio transmission resources relative to a starting point of the consecutive time-domain resources, which may indicate the quantity information and the location information related to the consecutive time-domain resources. Alternatively, the resource indication information may be a location of a starting point of the radio transmission resources in the consecutive time-domain resources and the quantity of basic time scheduling units contained in the radio transmission resources.
In a specific embodiment of the present disclosure, the first periodicity may be a repeat cycle of radio frames in a mobile communication system, a repeat cycle of uplink basic time scheduling units in a TDD mobile communication system, a repeat cycle of a synchronization signal in a mobile communication system, or an occurrence cycle of the uplink basic time scheduling units, and the like, which is not limited in the present disclosure.
It should be noted that, the basic time scheduling unit in LTE system here may be a subframe having a length of 1 ms, and it may also be other units having a shorter duration, such as a subframe having a duration of 0.5 ms, or may even be an OFDM symbol.
In a specific embodiment of the present disclosure, the method for resource indication may further include: transmitting the full configuration mode to the device at the receiving side. The full configuration mode may be used in determining the consecutive time-domain resources repeated in the first periodicity by the device at the receiving side.
The full configuration mode may include: a periodicity parameter used to describe the first periodicity, or a resource structure parameter, or a resource configuration parameter.
The resource structure parameter may be used to describe a structure of the consecutive time-domain resources.
The resource configuration parameter may be used to describe configuration information about forming the consecutive time-domain resources.
For example, the structure of the consecutive time-domain resources described by the resource structure parameter may be as shown in the following table 1:
For another example, the configuration information described by the resource configuration parameter may be as followed: the consecutive time-domain resources include ten subframes, the proportion of the number of uplink subframes, the number of downlink subframes and the number of special subframes is 4:2:4, the uplink subframes are between two special subframes, and the first subframe and the sixth subframe are the two special subframes. Accordingly, the structure of the consecutive time-domain resources as shown in the following table 2 can be formed based on the foregoing configuration information.
It should be noted that, the foregoing is merely an example of how to determine the periodicity of consecutive time-domain resources and the type of subframes from resource configuration parameters, and the present disclosure is not limited to the foregoing particular subframe structure.
Certainly, the less the indication information is, the less the system overhead is required. Therefore, in a specific embodiment of the present disclosure, which parameters may be applied to the full configuration mode can be decided according to actual applications.
Additionally, in a specific embodiment of the present disclosure, the consecutive time-domain resources repeated in the first periodicity and corresponding to the full configuration mode may also be defined by a network-side device and a device at the receiving side.
In a specific embodiment of the present disclosure, the transmitting the resource indication information may indicate that the receiving side requires to determine the transmission resources based on the resource indication information, and for the network side, it may be determined, in accordance with the resource indication information, whether or not the transmission resources will be selected.
In a specific embodiment of the present disclosure, indication information about a transmission result may also be transmitted by the network side. When the indication information about the transmission result indicates that the resource indication information has been transmitted, it is necessary for the device at the receiving side to detect and receive the resource indication information. When the indication information about the transmission result indicates that no resource indication information has been transmitted, the device at the receiving side may determine directly the consecutive time-domain resources as the radio transmission resources for interaction with the network-side device, instead of detecting and receiving resource indication information.
In this manner, the method for resource indication according to the embodiments of the present disclosure may further include: transmitting, to the device at the receiving side, transmission result indication information that indicates whether the resource indication information has been transmitted, to indicate the device at the receiving side whether to receive the resource indication information or not.
When the transmission result indication information indicates that the resource indication information has been transmitted, the device at the receiving side receives the resource indication information, and determines the radio transmission resources based on the resource indication information. When the transmission result indication information indicates that no resource indication information has been transmitted, the device at the receiving side directly determines the consecutive time-domain resources as the radio transmission resources for the device at the receiving side to interact with the network-side device.
The transmission result indication information may be transmitted by a base station through high-layer signaling and/or downlink control information. A mobile communication terminal is taken as an example as followed.
First Manner: Configuration Through High-Layer Signaling
In the case that a terminal is able to support the ability of determining part or all of time-domain resources from the consecutive time-domain resources as the radio transmission resources (hereinafter referred to as a resource selection mode), whether to transmit the resource indication information may be configured by a high layer signaling for the terminal.
If it has been configured by the high-layer signaling to transmit the resource indication information for the terminal, the resource selection mode is adopted in transmission directly by the terminal, according to the high-layer signaling.
Second Manner: Configuration Through Physical Layer Dynamic Control Information
In the case that base station may be aware of that a terminal is able to support the ability of determining part or all of time-domain resource from the consecutive time-domain resources as the radio transmission resources (hereinafter referred to as resource selection mode), a scheduling indication information bit may be added to downlink control information by adding a new bit or by using a reserved field, which indicates that the resource selection mode is to be adopted in transmission this time.
For example, the scheduling indication bit is added, if the bit is 1, it may indicate that the resource selection mode is to be adopted in transmission, i.e. resource indication information has been transmitted; and if the bit is 0, it may indicate that the resource selection mode is not to be adopted in transmission, i.e. no resource indication information has been transmitted. Alternatively, if the bit is 0, it may indicate that the resource selection mode is to be adopted in transmission; and if the bit is 1, it may indicate that the resource selection mode is not to be adopted in transmission.
Specifically, with respect to a terminal with the above ability, control information including the above scheduling indication may be used at network side, while with respect to a terminal without the above ability, existing protocol may be used.
At the terminal side, the foregoing downlink physical layer dynamic control information including the scheduling indication may be detected by a terminal with the foregoing ability, and whether the resource selection mode is to be adopted in transmission may be determined based on the value of the scheduling indication bit.
Third, joint configuration through high-layer signaling and physical layer dynamic control information
The third manner is a combination of the first manner and the second manner. The high-layer signaling configuration and dynamic indication may be performed simultaneously at the network side. For the terminal that supports the foregoing ability, the foregoing downlink physical dynamic control information including the scheduling indication may further be detected, if it has been configured, through high-layer signaling, that resource selection mode is to be used in transmission, and the type of current scheduling may be determined based on the value of scheduling indication bit.
If it has been configured, through the high-layer signaling, that the resource selection mode is not to be adopted in transmission, existing protocol may be used.

The transmitter may be configured to transmit the resource indication information to a device at a receiving side, and the resource indication information may be used to indicate the device at the receiving side to determine a part or all of time-domain resources, from consecutive time-domain resources repeated in a first periodicity and corresponding to a full configuration mode, as radio transmission resources for the device at the receiving side to interact with the network-side device.
The above embodiments may be referred to for specific implementations, which will not be described herein.
Referring to
In a specific embodiment of the present disclosure, the resource indication information may indicate quantity information and location information related to the consecutive time-domain resources.
In order to reduce system overhead, it is preferred that radio transmission resources are continuously distributed in a time domain.
Specifically, the resource indication information may be a location of a starting point of the radio transmission resources in the consecutive time-domain resources and the quantity of basic time scheduling units contained in the radio transmission resources.
In a specific embodiment of the present disclosure, the first periodicity may be a repeat cycle of radio frames in a mobile communication system, a repeat cycle of uplink basic time scheduling units in a TDD mobile communication system, a repeat cycle of a synchronization signal in the mobile communication system, or an occurrence cycle of the uplink basic time scheduling units.
In a specific embodiment of the present disclosure, the device for resource determination may further include:
a receiving module, configured to receive the full configuration mode from the network-side device; and
a second determining module, configured to determine the consecutive time-domain resources repeated in the first periodicity based on the full configuration mode.
The full configuration mode may include: a periodicity parameter, or a resource structure parameter, or a resource configuration parameter.
The periodicity parameter may be used to describe the first periodicity.
The resource structure parameter may be used to describe a structure of the consecutive time-domain resources.
The resource configuration parameter may be used to describe configuration information used for forming the consecutive time-domain resources.
Additionally, in a specific embodiment of the present disclosure, the consecutive time-domain resources repeated in a first periodicity and corresponding to full configuration mode may be pre-defined by the network-side device and the device at the receiving side.
In a specific embodiment of the present disclosure, the device for resource determination may further include: a selecting module, configured to directly select the consecutive time-domain resources as the radio transmission resources for interaction with the device at the network side, when no resource indication information has been received from a network-side device, or when transmission result indication information is received from the network-side device, and the transmission result indication information indicates that no resource indication information has been transmitted.
Therefore, based on the device for resource determination according to the embodiments of the present disclosure, part or all of time-domain resource are determined, based on the resource indication information received from the network-side device, from the consecutive time-domain resources repeated in the first periodicity and corresponding to the full configuration mode, as the radio transmission resources for interaction with a network-side device. The selected radio transmission resources may be either discretely distributed or continuously distributed from the consecutive time-domain resources. In such a manner, a flexible resource allocation can be achieved
Optionally, a device for resource determination is provided according to an embodiment of the present disclosure, which is applied in a device at a receiving side. The device includes: a processor, a memory connected with the processor via a bus interface, and a receiver connected with a processor via a bus interface. The memory may be configured to store programs and data used by the processor when the processor performs an operation.
The processor may be configured to call and execute programs and data stored in the memory, so as to: determine a part or all of time-domain resource, from consecutive time-domain resources repeated in a first periodicity and corresponding to a full configuration mode, as radio transmission resources for interaction with a network-side device, based on resource indication information, when the resource indication information is received from the network-side device by the receiver.
In addition, a network-side device is further provided according to an embodiment of the present disclosure, including the above-mentioned device for resource indication.
A device at a receiving side is further provided according to an embodiment of the present disclosure, including the above-mentioned device for resource determination.
