Description

Method for indicating resource allocation and indicating device, base station and terminal

Technical field

The present invention relates to the field of communications technologies, and in particular, to a method for indicating resource allocation when an LTE system operates in an unlicensed frequency band, a pointing device for resource allocation when an LTE system operates in an unlicensed frequency band, a terminal, and A base station.

Background technique

With the dramatic increase in communications ^{traffic, 3GPP (The 3 rd Generation Partnership} Project, the third generation mobile communications partner organization) licensed band increasingly insufficient to provide higher network capacity. To further increase the utilization of frequency band resources, 3GPP is discussing how to use unlicensed bands, such as the 2.4 GHz and 5 GHz bands, with the help of licensed bands. These unlicensed bands are currently mainly used in systems such as Wi-Fi, Bluetooth, radar, and medical.

In general, access technologies designed for licensed frequency bands, such as LTE (Long Term Evolution), are not suitable for use in unlicensed frequency bands because access technologies such as LTE are very demanding on frequency band efficiency and user experience optimization. high. However, the Carrier Aggregation (CA) feature makes it possible to deploy LTE in unlicensed bands. The 3GPP proposes the concept of LAA (LTE Assisted Access), which uses the help of the LTE licensed band to use unlicensed bands. The unlicensed frequency band can have two working modes, one is supplemental downlink (SDL, Supplemental Downlink), that is, only the downlink transmission subframe; the other is the TDD mode, which includes both the downlink transmission subframe and the uplink transmission subframe. . This situation can only be supplemented by the carrier aggregation technology. The TDD mode can be used independently of DC (Dual Connectivity). As shown in Figure 1.

Compared with Wi-Fi systems, LTE systems operating in unlicensed bands have the ability to provide higher frequency efficiency and greater coverage, while relying on the same core network to allow data traffic between licensed and unlicensed bands. Sew switch. For the user, this means a better broadband experience, higher speed, better stability and mobility.

Existing access technologies used in unlicensed bands, such as Wi-Fi, have weaker resistance Disturbance ability. In order to avoid interference, the Wi-Fi system has designed many interference avoidance rules, such as CSMA/CD (Carrier Sense Multiple Access/Collision Detection). The basic principle of this method is Wi-Fi. Before the AP (Access Point) or the terminal sends signaling or data, it must first monitor whether other APs or other terminals are transmitting/receiving signaling or data. If so, continue to listen until it is monitored. If not, a random number is generated as the backoff time. If no signaling or data transmission is detected during this backoff time, the AP or the terminal may start transmitting signaling or data after the end of the backoff time. The process is shown in Figure 2.

In order to ensure fair coexistence with WIFI, LAA proposes a variety of listening mechanisms based on FBE (Frame based Equipment) and LBE (Load based Equipment). When an LTE uses an unlicensed band, it needs to detect that the channel is idle before it can be sent, so that the unlicensed band cannot be continuously transmitted. In addition, in order to ensure the full use of the frequency band and the accuracy of the channel idle detection, the EU also stipulates that the bandwidth usage in the unlicensed frequency band should exceed 80%. In addition, since the coverage of the LAA SCell (Secondary Cell) is small and the number of UEs that can be scheduled is small, the number of Resource Blocks (RBs) allocated to each UE will be relatively large.

The number of bits occupied by the resource allocation (Resource Allocation) field in the traditional DCI (Downlink Control Information) signaling is relatively large. Specifically, it is determined according to the system bandwidth. Table 1 shows the method of indicating resource allocation by the allocation method of type 0. The left column indicates the system bandwidth, which is indicated by the number of RBs occupied by the system bandwidth. The right side indicates the size of the RBG (Resource Block Group), specifically N RBs. For example, when the system bandwidth is 10 RBs, The size of the RBG is one RB. Therefore, the resource Allocation field needs to occupy 10 bits to indicate the resource allocation of 10 RBs. When a certain bit is 1, the RB corresponding to the bit is allocated to the UE, otherwise it is 0. The RB corresponding to the bit is not allocated to the UE.

Table 1 Type 0resource allocation RBG size vs.Downlink System Bandwidth

Taking 50RB as an example, a schematic diagram is given, as shown in FIG. A set of 3 RBs requires a total of 17 bits to indicate.

Figure 4 shows the allocation of resources in the resource allocation mode of type 1, as well as the bandwidth of 50 RB. In Figure 4, the Resource Allocation field is divided into three domains. The first domain occupies the number of bits.

Indicates the RB that uses the first subset (subset), here is the third. The uppercase P here indicates two meanings: one means 50 RB, one RBG is P(3) RBs; the other means that 50 RBs are divided into P(3) subsets as shown in FIG. The second field occupies 1 bit, with 0 being the left-aligned allocation and 1 being the right-aligned allocation. The size of the third field occupying the number of bits is the number of bits in the resource allocation mode of type 0 minus the number of bits in the first two fields, 14 bits.

In the method of class 2 resource allocation to indicate resource allocation, use DCI format1A, 1B or 1D to use 1bit to indicate whether to use Type2 localized (distributed) or distributed (distributed) allocation method, and format 1C is always distributed method. . Regarding the centralized allocation method of Type 2, RB_start (resource block start point) and length (length) may be calculated according to RIV (Resource Indication Information) indication; and if distributed, RB_start and gap (interval) may be known. The Gap values are shown in Table 2 below.

Therefore, how to reduce the number of bits occupied by the resource allocation domain in the DCI signaling in the unlicensed frequency band, thereby reducing the signaling overhead, becomes a technical problem to be solved.

Summary of the invention

The invention is based on the above problems, and proposes a new technical solution, which can effectively reduce the number of bits occupied by the resource allocation domain in the DCI signaling in the unlicensed frequency band, thereby reducing the signaling overhead.

In the technical solution, the resource block group size and/or the resource block group size corresponding to the working bandwidth of the LTE system are adjusted, and the adjusted resource block group size is corresponding according to the working bandwidth. And/or the candidate value of the resource block group size determines the target resource block group size that needs to be notified to the terminal finally, and informs the terminal of the target resource block group size and the resource block group allocation information by target (designated) signaling, so as to achieve The terminal allocates the corresponding resource block, so that the terminal can allocate resources through multiple allocation modes, and can effectively adjust the resource block group size and/or the resource block group size selection value corresponding to the working bandwidth on the unlicensed band. The number of bits occupied by the resource allocation domain in the target signaling is reduced, thereby reducing signaling overhead.

In the above technical solution, preferably, the adjusting the resource block group size and/or the resource block group size selection value corresponding to the working bandwidth includes: increasing the resource corresponding to the working bandwidth. a block group size; or increasing the resource block group size corresponding to the working bandwidth and setting a plurality of selection values of the resource block group size corresponding to the working bandwidth; or setting a plurality of the work The available value of the resource block group size corresponding to the bandwidth.

In this technical solution, there are various options for adjusting the resource block group size and/or the resource block group size selection value corresponding to the working bandwidth of the LTE system in the unlicensed band. Specifically, the solution 1: increase The size of the resource block group corresponding to the working bandwidth, for example, for the resource allocation mode of type 0, the resource block group size corresponding to the working bandwidth of the 50 RB before the unadjusted is 3 RBs, and 17 bits are required for resource allocation indication, if the resource allocation is increased by 50 RBs The resource block group size corresponding to the working bandwidth is adjusted to 6 RBs, and the number of bits required for resource allocation is directly halved, which significantly reduces the signaling overhead, and may of course be increased by other ratios; The value of the resource block group size corresponding to the working bandwidth, for example, the resource block group size corresponding to the 50 RB working bandwidth before the adjustment is only one 3 RB, and the adjusted 50 RB working bandwidth corresponding resource The candidate value of the block group size may have multiple selection values of 6 RB, 7 RB, and 8 RB, and simultaneously increase the resource block group size of the selection value of each resource block group size (for example, 3 RB before adjustment, 6 RB, 7 RB, 8 RB after adjustment, all increase), obviously can further reduce the signaling overhead, and the number of candidate values of the resource block group size and the size of the resource block group increase The ratio can be set as required; scheme 3: setting a plurality of resource block size corresponding to the working bandwidth, for example, for the type 2 distributed resource allocation mode, the resource block corresponding to the 50 RB working bandwidth before the adjustment The selection value of the group size is only one 3 RB, and the available value of the resource block group size corresponding to the adjusted 50 RB working bandwidth may be 2 RB, 3 RB, 6 RB, 7 RB, 8 RB, that is, the original value is included, and the original value is A value with a small value and a value larger than the original value. By adjusting the resource block group size and/or the resource block group size selection value corresponding to the working bandwidth, the number of bits occupied by the resource allocation domain in the target signaling is reduced on the unlicensed band, thereby reducing signaling overhead and passing The above adjustment may allocate multiple resource block groups for each terminal.

In this technical solution, there are various options for adjusting the resource block group size and/or the resource block group size selection value corresponding to the working bandwidth of the LTE system in the unlicensed band. Specifically, the solution 1: increase The size of the resource block group corresponding to the working bandwidth, for example, for the resource allocation mode of type 0, the resource block group size corresponding to the working bandwidth of the 50 RB before the unadjusted is 3 RBs, and 17 bits are required for resource allocation indication, if the resource allocation is increased by 50 RBs The resource block group size corresponding to the working bandwidth is adjusted to 6 RBs, and the number of bits required for resource allocation is directly halved, which significantly reduces the signaling overhead, and may of course be increased by other ratios; The candidate value of the resource block group size corresponding to the working bandwidth, for example, the candidate value of the resource block group size corresponding to the working bandwidth of the 50 RB before the unadjusted is only one 3 RB, and the adjusted 50 RB.
