Embodiment 2

[0057] According to an embodiment of the present invention, a CB uplink transmission method is provided, Figure 7 It is a flow chart of the CB uplink transmission method according to Embodiment 2 of the method of the present invention, as shown in Figure 7 As shown, the method includes the following steps S702 to S704:

[0058] Step S702, the network side notifies the terminal of a CB-RNTI and a predetermined rule, and sends an uplink scheduling authorization signaling corresponding to the CB-RNTI to the terminal, wherein the predetermined rule includes that the resource size used by the terminal for CB uplink transmission is N, and the uplink scheduling The signaling is used to notify the resource information allocated to the terminal. The resource information includes the resource location and the allocated resource size. The allocated resource size is M×N, and M is a positive integer.

[0059] Step S704, the terminal performs CB uplink transmission according to predeterm...

Embodiment 3

[0063] According to an embodiment of the present invention, a CB uplink transmission method is provided, Figure 8 It is a flow chart of the CB uplink transmission method according to Embodiment 3 of the method of the present invention, as shown in Figure 8 As shown, the method includes the following steps S802 to S804:

[0064] Step S802, the network side notifies the terminal of a CB-RNTI, the first predetermined rule and the second predetermined rule, and sends high-level signaling to the terminal, wherein the first predetermined rule includes: the size of the resource used by the terminal for CB uplink transmission is N , the second predetermined rule includes: arranging rules for resources allocated by the network side for CB uplink transmission for the terminal, high-level signaling is used to notify resource information allocated for the terminal, the resource information includes the allocated resource size, the allocated resource size It is M×N, and M is a positive ...

Abstract

A contention-based uplink transmission method and device are provided in the invention. The method includes the following steps: an network side informs a terminal of one or more shared resource identifiers Contention Based - Radio Network Temporary Identifiers (CB-RNTIs) and sends uplink scheduling grant signalings corresponding to one or more CB-RNTIs to the terminal (S602), wherein: the uplink scheduling grant signalings are used for informing the terminal of resources which are allocated to the terminal for Contention Based (CB) uplink transmission and located between resources occupied by an uplink control signaling and that occupied by frequency hopping, and there is a one-to-one correspondence between CB-RNTIs and uplink scheduling grant signalings; the terminal performs CB uplink transmission by using the resources (S604). The invention reduces the overhead of Physical Downlink Control Channel (PDCCH) and the probability of collision between terminals, and alleviates the load of PDCCH public search space; meanwhile, it reduces the effect on frequency domain scheduling or Physical Uplink Shared Channel (PUSCH) frequency hopping, and improves the entire performance of the contention-based uplink signal transmission scheme.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a contention based (abbreviated as CB) uplink transmission method and device. Background technique [0002] In a Long Term Evolution (LTE for short) wireless system, a terminal (User Equipment, UE for short) sends a Scheduling Request (SR for short) through a Physical Uplink Control Channel (PUCCH for short) and The process of obtaining and sending uplink data is as follows: figure 1 As shown: the terminal sends an SR; the base station allocates an uplink scheduling grant (Uplink Scheduling Grant, UL Grant) to the terminal through a physical downlink control channel (Physical Downlink ControlChannel, referred to as PDCCH); The configured uplink grant) sends a buffer status report (BSR); the base station allocates an uplink grant for sending uplink data to the terminal through the PDCCH according to the scheduling strategy; Send uplink data for PUSCH). [0003] The above-ment...
