Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.
Referring to fig. 2, fig. 2 is a flowchart illustrating a resource allocation method according to a first embodiment of the present invention, where the method is applied to a network side device, and includes the following steps:
step 201: sending resource configuration information of a broadcast service to a terminal, wherein the resource configuration information comprises: frequency domain information of a Bandwidth Part (BWP) allocated to the broadcast service.
According to the resource allocation method provided by the embodiment of the invention, the resource allocation granularity of the broadcast service can be optimized by adding the frequency domain information in the resource allocation information, the resource allocation efficiency and the flexibility of the system are improved, and the resource waste is avoided.
In the above embodiment, the bandwidth part is a part of the system bandwidth.
Preferably, the frequency domain information includes: a Physical Resource Block (PRB) index of a frequency domain start position and a PRB index of a frequency domain end position; or, a PRB index of a frequency domain start position and a bandwidth size of the bandwidth part.
That is, the frequency domain location of the broadcast traffic is determined by a PRB index indicating a frequency domain start location and a PRB index indicating a frequency domain end location (e.g., 10 th PRB to 13 th PRB), or a PRB index indicating a frequency domain start location and a bandwidth size of a bandwidth part.
In the L TE system, the time domain indication is performed by configuring the MBSFN subframe, which is used to carry the service data of the eMBMS service.
Specifically, the resource configuration information further includes: time domain information of the broadcast service;
the broadcast service is an enhanced multimedia broadcast and multicast service, and the time domain information includes: and the position parameter of the MBSFN time slot is used for bearing the service data of the enhanced multimedia broadcast and multicast service.
That is, in the 5G era, the time domain indication is performed by configuring an MBSFN slot (slot) that is used to carry service data of the eMBMS service.
Wherein the location parameters include: position information of an MBSFN radio frame and bitmap information used for determining the position of an MBSFN time slot in the MBSFN radio frame;
the location information includes: radio frame location periodicity and radio frame location offset.
Specifically, the terminal receives the resource configuration information, determines an MBSFN radio frame for transmitting the eMBMS according to the radio frame position period and the radio frame position deviation, and determines the MBSFN time slot in the MBSFN radio frame according to bitmap information for determining the position of the MBSFN time slot in the MBSFN radio frame.
For example, there are 16 radio frames in a repetition period of 160ms, and each radio frame includes 10 slots.
First, it is determined which frames of the 16 radio frames are MBSFN radio frames.
The radio frame satisfying the following formula is an MBSFN radio frame:
SFN mod radioFrameAllocationPeriod＝radioFrameAllocationOffset
the SFN is a frame number of a wireless frame;
the radioFrameAllocationPeriod is a radio frame position period;
the radioFrameAllocationOffset is a radio frame position offset.
And after the MBSFN radio frames are determined, determining which time slots in the MBSFN radio frames are MBSFN time slots according to the bitmap information for each MBSFN radio frame.
For example: if the bit in the bitmap information is "1" indicating that the corresponding timeslot in the MBSFN radio frame is allocated as the MBSFN timeslot, and the bitmap information corresponding to an MBSFN radio frame is 0111001110, it indicates that timeslots 1, 2, 3, 6, 7, and 8 in the MBSFN radio frame are MBSFN timeslots, and timeslots 0, 4, 5, and 9 are not MBSFN timeslots.
The eMBMS service has more cells to transmit together, which results in multipath superposition between cells, and needs to use an Orthogonal Frequency Division Multiplexing (OFDM) symbol with an Extended cyclic prefix (Extended CP, CP) length, i.e., an Extended Cyclic Prefix (ECP). For the 3.5GHz band planned by the current 5G, the mainly used 30KHz subcarrier spacing does not support ECP, and only supports ECP at 60KHz and above.
Of course, there are fewer cells (e.g., 1-3) in the broadcast service to send service data, and in this case, only a Normal Cyclic Prefix (CP) is used.
Therefore, in some preferred embodiments of the present invention, ECP or CP may be indicated for a segment of bandwidth alone in a large bandwidth system.
Specifically, the resource configuration information further includes: the type of cyclic prefix supported by the wideband portion.
The types of cyclic prefixes supported by the bandwidth part include: a normal cyclic prefix or an extended cyclic prefix.
That is, whether the bandwidth part supports ECP or CP is indicated in the resource configuration information.
In some preferred embodiments of the present invention, the resource configuration information further includes: the subcarrier spacing.
Specifically, the subcarrier spacing may be 2n× 15KHz (n is an integer), such as 7.5KHz, 15KHz, 30KHz, 60KHz, 120KHz, 240KHz, etc.
The present invention will be explained in detail below by comparing the resource allocation information in the L TE system with the specific allocation manner of the resource allocation information in the embodiment of the present invention.
L TE system, the resource allocation information is allocated as follows:
as can be seen from the configuration of the L TE system, the resource configuration information indicates the time domain position of the MBSFN subframe in the broadcast service, but does not include the frequency domain information of the broadcast service.
In the embodiment of the present invention, the resource configuration information includes not only time domain information but also frequency domain information, and the specific configuration mode is as follows:
in the configuration of the above embodiment of the present invention, the bold characters are portions different from the configuration of the L TE system.
The field radioframe allocation period indicates the radio frame location period.
The field radioFrameAllocationOffset indicates a radio frame position offset.
The field MBSFN-BWP indicates frequency domain information of the bandwidth part, and in the resource allocation information, any PRB from the 0 th PRB to the 37949 th PRB indicates the frequency domain position of the bandwidth part (in other resource allocation information, a plurality of consecutive PRBs may indicate the frequency domain position of the bandwidth part).
The field subanticriersspacing indicates the subcarrier spacing.
The field cyclicPrefix indicates the type of cyclic prefix supported by the wide-band part, which supports extended cyclic prefixes in the above configuration information.
The field radioslotAllocationPeriod indicates the allocation period of the MBSFN slot, which corresponds to an integer multiple of 10 slots.
The field slotlocation indicates bitmap information for determining the position of the MBSFN slot in the MBSFN radio frame.
The field oneFrame represents bitmap information corresponding to the MBSFN slot positions in 1 MBSFN radio frame.
The field fourFrames indicates bitmap information corresponding to MBSFN slot positions in 4 consecutive MBSFN radio frames.
